    Information storage device and method of traffic information system
    The present invention relates to a traffic information system information storage device and method, and more specifically, to a reservation function of a traffic information system that transmits and receives traffic information using a radio broadcasting system to reflect traffic of a driver to reserve traffic information of a destination section. The present invention relates to a traffic information system information storage device and method for storing and grasping a traffic state of a road when a vehicle is operated.
    In recent years, as vehicle production sharply increased and the number of users increased, problems such as traffic congestion occurred.
    In order to solve the conventional traffic congestion problem, some radio programs provide traffic information such as congested roads, but it has not been practically helped due to local and time limitations.
    In the conventional traffic information, the information transmission method is unclear and based on the subjective judgment of the information, so that it is difficult for the user to understand the content of the information and thus cannot overcome the fragmentation in terms of the quality and quantity of the information.
    Recently, in order to solve the traffic information transmission problem, a traffic information system called a radio data system (RDS) has been developed.
    1 is a conceptual diagram of the above-mentioned traffic information system, which uses a radio broadcast wave, and transmits traffic information encoded by using a frequency modulation (FM) broadcast wave to transmit an in-vehicle traffic information receiver through a decoder of the traffic information system. It is a system that analyzes broadcasting waves and notifies traffic information to users by text or voice in real time.
    The following process of the traffic information system is operated.
    First, if various traffic information collected from an unmanned camera, a traffic operator, and other traffic detectors detecting traffic conditions are provided to the traffic information database in real time, the information collected in the information database is transmitted to the existing radio broadcast by a traffic information server. Deliver to the system (traffic broadcast, etc.).
    The radio broadcast system receives the broadcast wave at the in-vehicle traffic information receiver by outputting traffic information in the vicinity of the broadcast wave.
    When the user selects the destination section point to listen to the traffic information of the destination section, the traffic information receiver notifies the traffic condition by displaying the traffic condition of the point selected by the driver by voice or text.
    However, the function of the in-vehicle traffic information receiver does not have a reservation function so that the user can know the traffic situation of the desired destination section at the moment, but there is a problem that the change cannot guess the flow of the road situation.
    That is, there is a problem in that the driver cannot cope with the road situation of the destination section because the driver does not obtain the information transmitted while away from the vehicle.
    Accordingly, an object of the present invention is to add a reservation information storage function to the above-mentioned traffic information system to receive traffic information of a destination section even when the user is absent by the reservation function and to automatically store the traffic situation before the time required by the vehicle. The present invention provides a traffic information system information storage device and method for coping with a problem such as traffic congestion by checking a road situation of a destination section required when using the A / D.

    Best Mode for Carrying Out the Invention The present invention will be described in detail with reference to the accompanying drawings.
    As shown in FIG. 2, the configuration and operation of the present invention are as follows.
    A tuner unit 10 for tuning and outputting a frequency to receive only necessary traffic information when receiving a broadcast wave from an broadcasting station through an antenna; A control unit 30 which receives the traffic information output from the tuner unit 10 and controls processing, storage, and output; A keypad 20 for outputting a reservation function signal such as a reservation time or a destination section point so that the controller 30 performs a function such as a reservation; A memory unit 60 for storing data about traffic information processed by the controller 30 for each address; A display unit 40 which is displayed for the user to visually check by outputting the processed traffic information data of the control unit 30; By outputting the processed traffic information data of the control unit 30 is composed of a voice unit 50 that is output so that the user can be audibly confirmed.
    When the traffic information input from various traffic detectors on each road is transmitted from the traffic information broadcasting station to the broadcast radio wave, the antenna receives the broadcast wave.
    When the tuner 10 detects by tuning a required frequency among the frequencies received through the antenna, the detected traffic information is input to the controller 30 and processed.
    The controller 30 stores the traffic information in the memory unit 60 when a reservation operation signal is input from the keypad 20, and when the output signal is input from the keypad 20, the display unit 40 or the voice unit 50. Will be output via to notify the user.
    3 and 4 show the control operation of the traffic information system.
    If the user wants to depart to the destination after a few hours with the vehicle equipped with the traffic information system and wants to depart the traffic information of the destination section point before the departure, the user can make a reservation function using the traffic information receiver 100 in the vehicle before the departure of the destination. It works.
    To use the reservation function, the user operates the keypad 20 located on the front panel of the traffic information receiver to generate a reservation signal to operate the traffic information receiver.
    When the user receives the reservation signal generated by operating the reservation function button, the controller 30 requests input of a reservation start time desired by the user and a reservation end time that is time before boarding the vehicle. do.
    When the user selects a desired location from among the destination section points and inputs the reserved area of the button, the controller 30 receives a reserved area signal light in addition to the reserved time (S20, S30).
    For example, the user wants to depart at 6 am as a destination, inputs the reservation start time of the traffic information receiver at 3 am, the reservation end time at 6 am, and specifies 7 destination section points.
    The controller 30 detects a predetermined number of regions using reservation information of a destination section point input from the keypad 20 and allocates addresses and regions as many as the designated number in the memory unit 60 as shown in FIG. S40).
    The controller 30 continuously searches for the time after the operation is completed and detects whether the reservation start time is 3:00 am designated by the user (S50).
    The controller 30 performs a reservation function when it is designated at 3 am during time search (S60).
    The reservation function operation at step S60 is as follows.
    When the reservation start time comes, the controller 30 receives the traffic information continuously output from the external traffic information broadcasting station at the antenna and receives a signal output by being tuned by the tuner unit (R10).
    When the traffic information is input, the controller 30 analyzes the code and data of the input information as shown in FIG. 5 (R20).
    The controller 30 detects a corresponding area code in the analysis and analyzes traffic information of the corresponding code.
    The controller 30 determines whether the previous information stored in the memory address number of the corresponding region is the same as the newly input information (R30).
    The determination of the controller 30 compares the coded traffic information and will be described with reference to Table 1).
    Table 1
    Traffic information codeTraffic information OneThere is a lot of traffic. 10It is operating normally. 11There is a crash. ：：
    For example, if the corresponding address of the area A is 0010 at 1234ｈ and the newly input traffic code of the area A is 0010, the controller 30 compares the two codes to determine whether the other traffic information is the same traffic information. (R30).
    If the same information is input as described above, the controller 30 stores the same information at the same address 1234ｈ (R70).
    When the new traffic information received in the region A is different from the controller 30, the controller 30 checks whether the allocated memory of the data storage memory unit 60 allocated to the region A is full (R30). , R40).
    When the controller 30 determines that there is enough memory, the controller 30 stores and returns traffic information in the area 235h next to the address of the previous information 1235h (R70 and R80).
    If the allocated memory of the region A is in the full state, the controller 30 searches the memory regions allocated for each region to detect a code of the region having the lowest use frequency (R50).
    If the frequency of use of the area B is the smallest, the controller 30 allocates a memory area of a portion of the area B to a storage location for storing traffic information of the area A, and stores and returns the input traffic information. R60, R70, R80).
    The controller 30 continuously operates the reservation function operation until the reservation end time as described above, and when the reservation end time has elapsed or when the user inputs a return signal using the keypad 20 in the middle, the reservation function operation is stopped. (S50, S70).
    If the control unit 30 returns from the reservation function operation, the next operation performs an output operation according to the manipulation of the keypad 20 of the user (S80).
    As described above, in the embodiment of the present invention, when the driver wants to use the vehicle by preserving and storing the traffic information before driving the vehicle, the driver checks the situation before the road departure of the destination to the present and the like. It provides a traffic information system information storage device and method having the effect of selecting the optimal road to prevent abnormal traffic jams and the resulting derivatives to reduce the traffic congestion cost due to traffic congestion.
