In addition, when constant pressure is continuously operated in the pure water and ultrapure water production system, a solenoid valve is applied to operate the pressure during operation to prevent internal damage of the device and to remove the pressure at the operation stop.
    [62] 8 is a flowchart illustrating the overall control of the pure and ultrapure water control system according to the present invention.
    [63] First, the pure water and ultrapure water production system is initialized (S501), and the sensor for measuring pressure, capacity, pure and ultrapure water purity values, and filter values through system initialization is inspected (S502), and the result is output to the initial screen. (S502).
    [64] According to whether the key is input (S503), if the key is input, the key input is determined (S504), the mode is switched (S505), the sensor value is input (S506), and if the key is not input, the sensor value is immediately input (S506). Then, the sensor value is determined (S507), and the state determination, the pump control, and the corresponding surface are output (S508 to S510).
    [65] In the initial execution step, as shown in FIG. 9, when the set values of the 1st and 2nd regions are set in the power-on state (S511) (S512), the LED is turned on and turned off again (S513), the sensor test, the touch test, and the input key test. To execute in sequence (S514 ~ S515). Then, the flushing cycle (F / S) and the flushing time are checked (S517), and the prefilter is checked (S518), depending on whether the set value is about 200 mW / cm or more (S519). The pure LED display is turned on (S520), if it is less than or equal to the system initialization (S521), the touch graphic LCD is operated (S522) and the logo display is displayed on the main screen with reverse osmosis (RO), flushing (Flushing), system, Ultra Pure (UP), Recirculation (R / C), and Mode are displayed respectively, and if the corresponding state is turned off, execution ends (S523 ~ S525).
    [66] In the recirculation step, as shown in FIG. 10, the LED is turned on (S530) and the ultrapure water is applied according to the application of the ultrapure water (S531). If the ultrapure water is executed (S532), and the ultrapure water is not displayed, the main screen is displayed (S533). While the status is displayed on the screen (S533), depending on whether it is main (S534), if it is main, it is displayed on the main screen (S535), and if it is not main, it is pure (S536). Ask (S537), if not pure water (S538), depending on the application of ultrapure water, if the ultrapure LED is turned off to perform the ultrapure operation (S539 ~ S540), if not the ultrapure water and at the same time stop the regeneration device (S541).
    [67] In the flushing step, when the flushing starts as shown in FIG. 11, the state is turned on by the LED (S550), and depending on the application of ultrapure water (S551), and the ultrapure water is displayed on the screen together with the water drain (S552 to S553). Depending on whether it is main, pure, or ultrapure water (S554 ~ S557), if pure water is used to produce pure water with LED lighting (S558 ~ S559), if it is ultrapure water, it is displayed as an error (S560), and the flushing is paused. (S561).
    [68] The ultrapure water execution step is performed via the pre-filter as shown in FIG. 12 (S570), depending on whether the pressure is about 0.5kg / cm or more (S571), and when it is below, the low pressure is output together with the LED lighting (S572 to S573). If the pressure is checked and the reference pressure or more, the pressure level is checked (S574).
    [69] If the pressure is at high level, the LED is turned on and the high level is output (S575 ~ S577) .If it is not at the high level, depending on whether it is an error (S578), if it is an error, at least 1st is set according to the purity value (S579). ), If the 1st purity value, the LED is turned on (S580), the ultrapure water pack replacement is displayed on the LCD (S581), and if it is not the above 1st setting value, the ultrapure water pack on the LCD is executed with a purity value of 2nd or higher set as the ultrapure setting value. Display the replacement and exit with LCD off (S582 ~ S584).
    [70] If the pressure is not a high level error, recirculation, water drain and conductivity are displayed on the screen (S585 ~ S587), and then the production of main, pure and ultrapure water is stopped, and the result is displayed on the main screen (S588).
    [71] The pure execution steps are similar to the ultrapure water execution order as shown in FIG. That is, with pure running, the LED is turned on and passed through the pre-filter (S590 ~ S591), depending on whether the pressure is about 0.5kg / cm (S592). (S593 to S594), if the reference pressure or more, the pressure level is checked (S595).
    [72] If the pressure is high level, the LED is turned on and the high level is output (S596 ~ S598) .If the error is not high, the LED is turned on if the error is 1st according to the purity value of 1st or higher set to the pure setting value. Illuminates to indicate pure pack replacement on the LCD (S599 to S602), and if it is not the 1st purity value set to the pure set value, the pure pack replacement indication is displayed on the LCD with a purity value of 2nd or more and ends with the LCD off (S603 to S605). ).
    [73] If the pressure is not a high level error, the water drain and the conductivity is displayed on the screen, and in turn stops the production of the main, pure and ultrapure water, and outputs the result on the main screen (S606 ~ S608). In this case, the pure water is stopped, and when the LED is turned off, the ultra pure water is executed.
    [74] As described above, the present invention can apply a touch input method and a key input method by controlling a touch and a key signal through an operation unit as an input method, thereby realizing diversification of input methods for pure and ultrapure water production.
    [75] As a control method, the value read from the sensor can be matched with the value displayed on the display, so the reliability and accuracy are improved due to the matching of the read value and the output value.
    [76] According to the time setting, it is possible to measure more than 5 times in about 1 second, so it is possible to measure the exact value, and to store the pressure, capacity, information, and reference values necessary for system operation through the memory unit, and graphic that can be controlled through the LCD controller. By applying LCD, you can check the system driving status at a glance, and check the driving status of the pump or error through the pump control unit.
    [77] Also, graphic LCD which displays pure and ultra pure water and error status in graphic, Korean, English, and letters, and a large number of LEDs that display driving status such as power, pure water, ultra pure water, U / V lamp, and check driving status. By applying a touch panel and a speaker that outputs a voice message for errors during overdrive, the display panel can display driving conditions more precisely.
    [78] In the deformation and error display of the reference value, two values that are basically set for the three functions of pure water, ultrapure water, and flushing can be modified using simple operations, and various functions can be operated simultaneously with a single operation.
    [79] In case of error detection, if an error is detected in the set values such as pure water, ultrapure water, and flushing, the error status is displayed after self-diagnosis for each, and the value input from each sensor is compared with the reference value and automatically adjusted. I can display it. In addition, if the filter is a filter pack, it is possible to bundle the filters required for pure and ultrapure water production into one filter.
    [80] Sensors applied as sensing means are approximately four, divided into pressure sensors for measuring pressure, capacitive sensors for measuring capacity, purity value sensors for detecting pure and ultrapure purity values, and free sensors for measuring prefilter values. The sensor that measures the pure and ultrapure water value, especially when the pure water is filled in the tank in the pure container, is to stop the production of the pure water temporarily and keep the value of the pure water constant. It is possible to reduce the fluctuation of the value of, to protect the system and to measure the pure water value more accurately. Pre-sensor is a sensor that measures the value of the filter which has the function of filtering out the green water or particles on the raw water before the pure or ultrapure water is obtained, and the filter value is about 200 to obtain more accurate pure and ultrapure water value. If it is over ㎲ / cm, the filter causes brown transition, so the pure or ultrapure water value drops, and the free sensor is applied to inform the change. Therefore, by applying the free sensor, more accurate pure and ultrapure water values can be measured, and brown transitions can be seen without looking at the filter, and the filter replacement time can be easily known.
    [81] In the conventional case, the display unit was a one-piece structure in which the furnace plate and the display unit were one, but the present invention applied the separated form of the circuit board PCB board and the display unit, so that the screen is freely enlarged, there is little risk of damage, and the display unit is damaged when the display unit is damaged. It can be repaired only by removing it, and it is also possible to adjust the position of the display unit on a commercial basis.
    [82] The present invention can be easily mounted to the drive display device when applied to the pure water and ultrapure water production apparatus can observe and control the driving state at a glance, and the display can be easily, so that the optimal control of the pure and ultrapure water production apparatus and the drive of the system The effect is that the user can easily see the status.
