Problems solved by technology

[0002] Industrial computer motherboards often encounter various complex situations such as repeated power-on, power-off or illegal power-off. In the R&D and testing phase, it is necessary to test the stability of repeated power-on and power-off and the adaptability of illegal power-off of industrial computers. At present, manual testing is used. In this way, the industrial computer is repeatedly turned on and off and illegally powered off to test its stability, so as to determine the performance of the computer and provide guarantee information for putting into production. However, the cost of manual testing is relatively high, and the efficiency value is relatively low. Especially in the face of different test environments and aging tests, manual work is time-consuming and laborious

Embodiment 1

[0050] Such as Figure 1-7 As shown, a switch machine stability test module is connected between the industrial computer host and the AC power supply, including the main control circuit, a level detection circuit connected to the main control circuit, a 232 communication circuit, a relay circuit, a display circuit and The key circuit, the level detection circuit is used to connect the ON / OFF key of the industrial computer main board, the communication circuit is connected to the RS-232 serial port of the industrial computer main board through the serial port connection line, and the relay circuit is also connected to the AC power supply and the industrial computer The power interface of the computer motherboard, the main control circuit controls the power supply to the industrial computer motherboard through the control relay circuit, the display circuit is used to display the setting and status of the test mode, and the button circuit is used to set and select the test mode. ...

Embodiment 2

[0053] Such as Figure 8-12 As shown, a method for testing the stability of power on and off is based on the hardware structure in Embodiment 1, copying the program for automatically sending serial port signals at startup to the startup item of the industrial computer operating system, setting the power on and off cycle mode and the illegal power-off control mode , by selecting different power-on / off cycle modes or illegal power-off control modes to test the industrial computer host, and feed back the test results to the power-on / off stability test module and display them on the display. Among them, setting the cycle mode of switching on and off and the illegal power-off control mode include the first time from the AC power on to triggering the power-on, the second time from the AC power cut-off to the re-starting of the AC power, and the third time to judge whether the power-on is successful by receiving the serial port signal. The fourth time when the power-off mode enters t...

Embodiment 3

[0057] Such as Figure 9 As shown, the difference between this embodiment and Embodiment 2 is that this embodiment selects the WINDOWS incoming call self-starting mode, and the test process is: select the WINDOWS incoming call self-starting mode, click the OK button to enter this mode, and enter the first mode of this mode. The first setting item is "AC OFF2ON TIME", which is to set the second time, the default is 5S, and the maximum can be set to 999 seconds. This item sets the time from cutting off to turning on the AC power; then set the third time, that is, 232 communication The time for the circuit to receive the serial port signal is set to 5 minutes in this embodiment. After the setting is completed, click the OK button to confirm and enter the test. The main control circuit turns on the AC power switch through the relay circuit to power on the main board of the industrial computer; the industrial computer starts up automatically, and the main board of the industrial c...

Abstract

The invention provides an on / off stability test module and an on / off stability test method. The test module comprises a main control circuit, and a level detection circuit, a 232 communication circuit and a relay circuit connected with the main control circuit, wherein the level detection circuit is connected with an ON / OFF key of an industrial computer mainboard; the communication circuit is connected with an RS-232 serial port of the industrial computer mainboard through a serial port connection line; the relay circuit is further connected with an alternating-current power supply and a power interface of the industrial computer mainboard; and the main control circuit controls power supply of the industrial computer mainboard by controlling the relay circuit. By use of an intelligent hardware circuit, the industrial computer mainboard can be subjected to multi-mode on / off stability testing without attended operation, so that the labor cost is greatly reduced, different test environments can be simulated, and the stability of the industrial computer mainboard can be repeatedly tested; and the test module and the test method are low in cost, simple in operation and high in practicality, and have the advantages of powerful functions, outstanding anti-interference capability, high stability and high universality.
