Air pressure measuring device 10
The invention relates to an air pressure measuring device for testing
Compressed air brake systems with at least one pressure sensor and at least one compressed air connection, as well as an associated brake pressure test system and a method for testing the compressed air brake systems of rail vehicles. 15
Rail vehicles have several for safety reasons
Brake mechanisms, wherein the service brake are generally air brakes. These air brake systems require periodic maintenance and inspection. From the prior art Bremsprobe- or brake testers for 20 testing the air brake systems of vehicles, especially trucks or rail vehicles are known. For example, AT 504 084 A1 describes a device for testing pneumatically actuated brakes of rail vehicles, which is connected via a compressed air hose to the rail vehicle to be measured. 25
During brake pressure measurement, the air pressure in the air brake system to be measured is monitored while the brake is activated or deactivated. The brake response time is the time from exceeding a certain pressure start value to the application of a required pressure stop value, and the brake release time is that time from falling below the pressure stop value to below the pressure start value. In the simplest case, such a brake pressure measurement can be done manually with a stopwatch and manometer, but this can not meet the accuracy requirements. Instead, automatic brake testing systems are used which are connected via compressed air hoses with the t ··· Ι · Μ

be connected to be measured air braking systems. The control of the brake test process is automatic, for example with a programmable logic controller (PLC).
One problem with automatic brake testing systems is that the compressed air hoses used to pressurize the compressed air brake system with compressed air should not exceed a certain length, for example 30 meters, in order to avoid pressure loss and resulting measuring errors. Thus, in a train, which often reaches lengths over 200m, the brake tester must be repositioned for each car to be tested. 10
To remedy this problem, EP 1 103 437 A2 describes a brake test system for checking the function of brakes in rail vehicles, which in particular has additional devices which are connected to a central brake test device by an electrical signal line or a radio link. Such additional devices include, in particular, pressure sensors for measuring the pressure drop, and transmission means for transmitting the measured values to the brake test system. Although these additional devices make it possible to carry out a sufficiently accurate test of the brake function at a large distance from a central brake tester, they are fixed in place, which makes versatile use of these devices much more difficult. In particular, a check can only be made at certain points. Furthermore, simultaneous testing of the air brake systems of several cars is not possible.
In addition, modern rail vehicles usually have more than 25 independent independent braking systems
Compressed air brake systems that can be tested with the known brake testers just as little at the same time, since, for example, always only one air pressure measuring device is provided for a car stationary. The technical object of the invention is thus to provide an air pressure measuring device which is portable and can be used independently of the location of the brake test system. Another technical problem is that several air pressure measuring devices are used simultaneously, and in particular that multiple air brake systems of a wagon
* ···································································································. · · · Can be checked simultaneously. Finally, the duration of the braking process should not only be measured centrally, but also locally on the air pressure measuring device itself. The measurement should be as accurate as possible and pressure losses due to long lines avoided.
These technical objects are achieved according to the invention in that the air pressure measuring device is designed to be portable and comprises control electronics, a user interface, a radio transmission unit and a time detection unit which measures the response times 10 of the compressed air brake systems.
Such an air pressure measuring device makes it possible to carry out measurements of the air pressure of one or, when using a plurality of air pressure measuring devices 15, also of a plurality of compressed-air brake systems, independently of location and at considerable distances from the central brake pressure test system. By providing a user interface on the air pressure measuring device itself, the measuring process can also be influenced locally, and not only centrally at the central brake testing system. For the same reason, a time detecting unit is also provided on the air pressure measuring device itself. It may be provided according to the invention, air pressure measuring device comprises a radio transmission option. This can be a WLAN, GSM or any other radio transmission option which communicates with a corresponding radio transmission unit of the central brake pressure test system. The communication can also take the form of UIC or other 25 wired connections, in particular bus connections for connecting multiple devices.
Furthermore, the air pressure measuring device may include a status display, an electric battery for power supply and one or more buttons. In particular, in local use without a central brake tester is thereby made possible to carry out the test of compressed air brake systems locally. For this purpose, it can be provided that the status display can also itself display measurement data, in particular measurement times. However, the status indicator is not a necessary part of the invention. 4 ··· ♦ # ♦ · »• * • · · ·
It can be provided that the status display comprises an LED, which in particular indicates the state of charge of an internal battery. When the air pressure measuring device is switched on, the status display can also be used to indicate that a zero point calibration must be carried out before the measurement can be started. The zero point adjustment itself can be done for example by pressing a button on the air pressure measuring device.
Furthermore, the invention comprises a brake pressure test system for testing the 10 compressed air brake systems of rail vehicles with at least one compressed air connection, a data processing unit and a user interface, the brake pressure test system comprising a radio transmission unit, which communicates with at least one air pressure measuring device according to the invention. According to the invention, the radio transmission unit of the brake pressure test system may comprise a WLAN, GSM or any other radio-based transmitting and receiving unit. But it is also any other radio transmission unit part of the invention, as well as a wired transmission unit.
It may be provided according to the invention that the brake pressure test system 20 comprises compressed air connections, in particular a factory air connection, a main air connection and a main air container connection. Furthermore, at least one additional compressed air connection may be provided for the connection of further compressed-air brake systems, in particular for the connection of an automatic load-dependent brake. 25
Furthermore, the Btemsdruckprüfanlage invention can be connected to a connected to a rail vehicle ramp controller in order to reduce the line resistance in the measurement of a longer Zuggamitur (train). In this case, not only the valve on the brake pressure test system, but also a second valve on the ramp controller is opened when venting of the measured 30 air brake system of the rail vehicle, whereby the venting takes place faster and delays are avoided due to long compressed air lines in train assemblies. The connection between the brake pressure test system and the ramp controller can also be wirelessly transmitted in the form of a 5 »** ♦ ♦♦ * ·
GSM, WLAN or any other wireless connection, or wired, for example in the form of an UlC connection.
Finally, the invention comprises a method for testing the
Pneumatic brake systems of rail vehicles with a 5 Bremsdruckprüfanlage invention comprising the following steps: a. Connecting the air pressure monitoring device according to the invention to the compressed air line of the compressed air brake system of the rail vehicle to be tested; that of the 10 b. wireless transmission of a command data packet brake pressure test system to the air pressure measuring device; from the c. Measurement of brake response time or brake release time Air pressure gauge device; through the d. Wireless transmission of a measurement data package Air pressure measurement device to the brake pressure test system. from the 15th
It may be provided according to the invention that step c) of the method according to the invention comprises the triggering of the brake function on the compressed-air brake system and step d) the measurement of the brake response time between the time of the pressure increase and the time of the filled state by the time-recording unit of the air pressure measuring device according to the invention.
It can be inventively further provided that the step c) in the process according to the invention, the termination of the brake function (solution of the brake 25) on the compressed air lines and the step d) the measurement of the brake release time between the time of pressure drop and time of the unpressurized state by the time recording unit Air pressure measuring device comprises.
In this context, 'non-pressurized' always means that the air pressure falls below a certain threshold, while 'filled1' means that the air pressure exceeds a certain threshold. For example, the control operating pressure of the main air line is usually 5. At this pressure, the brake is released. If the driver initiates braking, the pressure in the main air line is lowered. The normal service braking is initiated with a pressure reduction of 0.4-6 1.5 bar (full braking), while the quick, forced or emergency brake (NB) vents the main air line to ambient pressure. To release the brake, the pressure is raised again to the normal operating pressure.
Furthermore, a plurality of air pressure measuring devices can be provided, wherein the measured data packets are transmitted sequentially from one air pressure measuring device to the next air pressure measuring device until the last one
Air pressure measuring device, the collected data packets sent back to the brake pressure test.
Analogously, the command data packets can first be transmitted from the brake pressure test system to a first air pressure measuring device, and then sequentially from one air pressure measuring device to the next air pressure measuring device to the last air pressure measuring device.
For this purpose, it can be provided that each air pressure measuring device has a unique identification (ID), and each air pressure measuring device only evaluates those command data packets which have their own ID.
The measured data packet, which is transmitted from the air pressure measuring device back to the brake pressure test system, may comprise at least one unique identification of the air pressure measuring device (in particular its own ID) and the measured time span in the form of the brake response time or brake release time measured in step c). Furthermore, the measurement data packet may include the measured pressure value, a correction factor, as well as the current state of the user interface. In particular, the current state of the user interface may include one or more depressed keys.
Finally, as mentioned above, the command data packet may include at least one unique identifier of the air pressure measuring device (its ID) and at least one unique identifier specifying whether pressure drop or pressure increase should be measured. The command data packet may also include the print start value and / or print stop value to be used.

FIG. 2 shows a schematic block diagram of the air pressure measuring device 1 according to the invention, the essential functional elements being illustrated. First, a control electronics 5 is provided, which may be 5 in particular in the form of a microcontroller. The control electronics 5 is powered by an electric battery 10 and is connected to the user interface 6. Furthermore, it is in connection with a time recording unit 8, the pressure sensor 3, a status display 9 and a radio transmission unit 7, which may be designed in particular as a WLAN transmitting and receiving module io. The pressure sensor 3 is connected to the compressed air connection 4, wherein additionally a (not shown) valve, in particular solenoid valve, may be provided to selectively block the compressed air connection 4.
FIG. 3 shows a schematic block diagram of a brake pressure testing system 12 according to the invention. The latter in turn has a data processing unit 15, which can be embodied, for example, in the form of a built-in computer, laptop or a microcontroller unit. The data processing unit 15 is connected to a user interface 16 and a radio transmission unit 17, wherein the user interface may include means for inputting and outputting data. The radio transmission unit can in turn be set up for WLAN or GSM networks. In the present exemplary embodiment, the brake pressure testing system has a factory air connection 18 for connection to a compressed air supply, as well as numerous compressed air connections 14. These include, in particular, a main air connection 19, 25, a main air container connection 20, as well as further compressed air connections 21. These are compressed air outlets that are specifically supplied with compressed air can be acted upon, for example, a weighing valve. To control these compressed air connections, in particular a programmable logic controller (35) may be provided, which communicates with the data processing unit 15, but the device according to the invention should not be limited thereto. Furthermore, the Bremsdruckprüfanlage 12 has an electric emergency brake lock (NBÜ) 36, which serves to continue the train when the emergency brake is actuated and to bring only at a suitable location to a standstill. • ft * ♦ • ··········································· •

4 shows an exemplary embodiment of a brake pressure test system 12 according to the invention, which is connected to a rail vehicle 13 and communicates with an air pressure measuring device 1 according to the invention for testing the air pressure brake system 41, which is connected to the rail vehicle 13 via compressed air hoses. The rail vehicle 13 comprises the compressed air lines 2, in particular the main air line and the main air reservoir line, which has valves 34 (compressed air coupling HL) and 39 (compressed air coupling HBL) at both ends of the rail vehicle for connecting further vehicles. Via a brake cylinder line, the brake cylinders 40 of the rail vehicle are connected to a control unit. When lowering the pressure in the main air line, the pressure in the brake cylinder line increases and braking is initiated. Of course, the air brake system of a railway vehicle is much more complex and, for clarity, only selected details are shown in this figure.
The Bremsdruckprüfanlage 12 is connected to the factory air 33 and supplied at their compressed air connections 19, 20 and 21, the various compressed air lines 2 of the rail vehicle 13. In particular, it is provided that the main air line and the Hauptluftbehäiterleitung are connected to the main air port 19 and the main air tank port 20. The compressed air connections 21 are connections for supplying an automatic load-dependent brake. Fig. 5 shows the time profile of the air pressure in a brake cylinder of a rail vehicle 13 with a dashed line and the main air line with a solid line using the method according to the invention. First, the air pressure in the main air line is high, in particular above the 30, which for example has a value of 4.8 bar. The brake 30 is actuated, whereupon the air pressure in the main air line decreases and the pressure in the brake cylinder rises.
As soon as the air pressure rises above the pressure start value 31 at the time of the pressure increase 28, the brake response time 23 is measured until the air pressure reaches the level of...... *
Ol 'Fl) Η
Pressure stop value 30 reached. This time is referred to as the time of the filled state 29, the brake is actuated.
After this measurement, the brake is released again, whereupon the air pressure in the main air line rises and falls in the brake cylinder line. At the time of 5 pressure drop 24, the air pressure is equal to the pressure stop value 31, and the brake release time 27 is measured until at the time of the non-pressurized state 25 in which the brake cylinder pressure is equal to the pressure start value 31 again. and the brake is released. FIG. 6 shows an embodiment in which a central brake pressure tester 12 is provided which communicates with a plurality of air pressure measuring devices 1 mounted on different interconnected rail vehicles 13. In this case, the rail vehicles 13 must be supplied with compressed air only at one point, since both the main air line and the 15 main air reservoir line by compressed air couplings 34, 39 are interconnected. Both the Bremsdruckprüfanlage 12, and the air pressure measuring devices 1 are connected with short compressed air lines to the rail vehicles 13, whereby the accuracy of the measurement can be optimized. Again, further compressed air lines 21 are connected to the rail vehicle to demonstrate that different brake systems, particularly the
Service brake and the load-dependent brake, can be measured simultaneously. In particular, several air pressure measuring devices 1 can be connected to different compressed air lines of a single rail vehicle 13. In order to ensure error-free data transmission of the measured data to the central brake pressure testing system 12, the air pressure measuring devices 1 have unique identifiers (IDs). This is used to identify the measured data and to address a specific air pressure measuring device 1. 30 Furthermore, Fig. 7 shows the connection of a ramp controller (38) to the
Compressed air coupling of the main air line (HL) 34 of the rail vehicle. The ramp controller is also connected to the brake tester 12. When the braking operation is triggered via the brake tester 12, the ramp regulator (38) vents the main air line, making it faster, in particular with long train assemblies
•··············································································································································································································· ··· depressurized. This is useful if the response time of the brake cylinder to be measured, without distorting the measurement results, due to the physical properties of the compressed air in long compressed air lines (breakdown speed about 250 m / s) is necessary. 5
Finally, FIG. 7 shows the course of the message transmission between the brake pressure test system 12 and the air pressure measuring devices 1 of the exemplary embodiment from FIG. 6. In the present exemplary embodiment, four air pressure measuring devices are provided which have the identifications ID1, ID2, ID3, and ID4.
Instruction data 22 is generated by the brake pressure test system 12 (in particular by the programmable logic controller 35 or the data processing unit 15) and sent to the pressure sensor with the ID1. If the command data packets 22 are intended for him, he executes the command. Otherwise, the command data packets 22 are forwarded to the next barometric pressure measuring device 1 with the ID2. For example, if the command relates to the air pressure measuring device having the ID4, the command data is passed until it reaches the air pressure measuring device with the ID4. Command data is passed on for 2o until the brake pressure tester 12 stops sending the command data.
In particular, the format of the command data 22 may be constructed as follows: 25 IDO / 1: start, stop ID ... Air pressure measuring device concerned 0/1 ... Measurement of brake response time / brake release time
Start / Stop ... Pressure start value / Pressure stop value 30
For example, 10: 200,900 is an order for the ID 1 air pressure measurement device to measure the brake response time, taking into account a print start value of 200 digits and a print stop value of 900 digits. The command data 31: 1000,55 is a command for the air pressure measuring device having the ID 3, which is "* *" "*. · A · *** · ···· · «··
12
Brake release time, taking into account a starting pressure value of 1000 digits and a pressure stop value of 55 digits.
With the transmission of the measured data packet 26, the air pressure measuring device 1 s begins with the ID4. The air pressure measuring device with the ID3 is waiting to receive the data. If the ID3 receives the measurement data packet 26, it appends its own measurement data and sends the entire data packet as measurement data packet 26 to the air pressure measurement device with the ID 2, etc. If an air pressure measurement device does not receive any data, the measurement data of the previous cycle are used and forwarded. This happens three times, if then still no data was received, then only the own measuring data are passed on and the faulty air pressure measuring device is not considered. The air pressure measurement device with the ID1 receives the entire measurement data packet 26 and forwards it to the brake pressure test system 12. In the normal case, these are the measurement data of all four air pressure measuring devices.
The format of the measured data 26 can be structured in particular as follows: ID: pressure value, correction factor, measuring time, key definition ID air pressure measuring device involved 20 pressure value Measured pressure value in digits Correction factor Fixed Correction factor Measuring time Measured time in ms Key function, for example 0 pressed for no key, 1 for first key pressed, 25 2 for second key pressed, 3 pressed for both keys.
For example, the measurement data 1: 55.0.5, 4555.3 means that the measurement data of the air pressure measurement device is ID1, the pressure value is 55 digits, the correction factor is 0.5, the latest time measurement is 4555 ms, and at the moment both buttons are operated are.
Of course, the invention is not limited to the exemplary embodiments shown and also includes other devices or methods in FIG. 13
Framework of the inventive concept. In particular, the invention also includes air pressure sensing devices for use with trucks or other non-rail vehicles having pneumatic brakes. * # * ···· «· * · ·« ·· • · · * · · · · ·
