Power automatic control device is a device that automatically controls the power supply of electric heating equipment and other electric heating equipment according to the set condition.As shown in the representative diagram, the temperature sensor unit detects the temperature of the heat storage unit, and supplies it to the power and heating element flowing into the device. Power input detection sensor to detect the input of power, Key operation and display for mode operation and selection, setting and status of the device, Memory to store its own operation and status data, Real time clock to control device It is composed of a Timer unit for providing a power supply unit for supplying AC commercial power to the operating power of the control device, and a power supply signal generator for operating SW2 for supplying power to the heater under the control of the control unit as shown in FIG. have.

In order to check the operation status and abnormality of each block of the power automatic controller which has such a structure, enter the test mode by inputting the combination key on the reserved key control unit and test each block by automatic batch test and manual test. It is a power automatic control device test device that automatically switches to the basic operation mode when all the tests are finished after outputting to the display unit.

Description

Test device of power automatic control device {Test Controller}

The present invention is a self-functional test technology that tests power automatic control device having the same structure as the representative figure (hereinafter referred to as control device) for each block in its own device without any test equipment or equipment and outputs the result to the display unit. to be.

Conventional control devices require separate test equipment for inspection after installation or cause analysis when an unknown abnormality is found, and a professional manpower is also required because testing is impossible without the expert knowledge of the control device. Due to these problems, a lot of time, physical and human resources were required for equipment, inspection, and abnormalities.

In order to solve this problem, the present invention enables self-testing by using a control unit, a display unit, a key operation unit, etc., which are configured together with a control unit without any separate test equipment. In addition, it is possible to test the general users who do not have expertise in the control device by systematicizing the test method and structure, and to obtain the accuracy of time and inspection by the automatic test mode control by Micom.

The test device enters the test mode through one or more promised key combination inputs of the existing key control unit (representative diagram), and after entering the test mode, according to the structured test sequence and method as described in FIG. Test each block of control device automatically or manually. At this time, the inspector has a function of outputting the display part (representative diagram) so that the tester can know the test contents and the result. When all the tests are completed, the control unit is a power automatic control device test device that automatically switches from the test mode to the basic operation mode to perform the basic operation of the control device.

Figure 2. Test Mode Flowchart

Figure 3. Test Run List and Results Display Example Sequence Table

The test apparatus is composed of a test mode entry, an automatic execution test mode, a manual execution test mode, and a test mode exit.

1. Enter Test Mode

: When one or more reservation keys are pressed or a separate Test Mode entry key is pressed on the key control panel of the controller (representative diagram), a test entry signal is transmitted to the controller (representative diagram). Compare the input key with the reserved key to see if the two keys are the same. Then, enter the test mode from the basic operation mode. At this time, the buzzer sound or all display parts of the control device (representative diagram) are turned on to indicate that the test mode has been successfully entered. In addition, when the initial test mode is entered, all display units are turned on, which also serves as a test of the display operation of the control device. Once in Test Mode, set Test_mode to '1' in Step 4 of Figure 4 and jump to Step 3 and 4 through the comparison of Step 2 until you exit Test Mode. do.

2. Run Test

: When entering test mode, as shown in Figure 3, when a scheduled test command is automatically executed in sequence without external manipulation, when one or more key combinations are pressed on the key control panel of a control device (representative diagram) Each time, the control unit judges whether the TestKey is pressed (Fig. 2-5) and increases the Testcount (Fig. 2-7), and the TestKey_count is compared at the bottom (Fig. 2-8) and according to the test execution order shown in Fig. 3 Manual Execution by Steps Run the test in one of the test modes.

At this time, it outputs the TestKey Count that is currently in progress so that the user can know the test status and whether the load is normal or abnormal according to the test execution result on the display on the control device.

① Display operation test

: The display part is made at the same time as entering the test mode without any additional operation, and all the display parts are turned on without checking the TestKey_count and the test result separately, and visually check the operation.

② Test of each sensor operation

: The heat storage tank temperature detected by one or more temperature sensors (Fig. 1) attached to the boiler body heat storage tank is displayed on the display part (representative view) of the automatic control device. Error is displayed. In addition, it tests the operation of the power input sensor (Fig. 1 SS1, SS2) that detects whether the late-night power is supplied from the late-night power supply and whether the power supplied to the heater of the boiler body is supplied.

③ Power supply signal generator test

: Operate the power supply signal generator (Fig. 1) to test whether SW2 (Fig. 1) is normally open or closed, and display an error when an abnormality is found.

④ Memory Test

: Input random data into memory to test whether read / write is normal and display error when error is found. After the memory test, initialize all the data entered for testing.

⑤ Timer Test

: Displays current time on display part of automatic control device and shows error when Micom and Timer communication test error occurs.

1. It is possible to test the function and status by the controller itself without any measurement equipment or test equipment.

2. Due to the systematic structured test method and easy user-centered interface such as simple operation and test result output, even general users who do not have expert knowledge about the control device can easily test the control device and find the cause of failure when abnormality is found. have.

3. Since all tests are done automatically in the control unit using Micom, it prevents wrong cause analysis caused by inspector's mistake and guarantees test reliability.
