[0021] Test example

[0022] Taking a 16-input / 14-output controller test as an example, first, according to the input and output points of the controller, 2 8-input / 8-output unit modules, a power module, an instrument module, and a communication module are configured on the hardware. On the software, the input and output points and the input and output types of the controller are correctly configured. Then, the device under test is connected to the 2 8I / 8O modules, the power module, and the communication module through a wire harness. The signals shared by different modules are connected through the BNC socket and the insulating terminal at the back, such as the 24V power supply required by each 8-input / 8-output module for the relay module and other devices. The power module will pull the 24V switching power supply signal to the corresponding terminal post at the back, and then the 24V power supply terminal posts of the 2 test 8-input / 8-output modules are connected to the 24V power supply terminal post of the power module. Then, the device under test downloads the test program, and the program communication protocol of the test tool upper computer is consistent, so that the digital high-level input effective (DIH), digital low-level input effective (DIL), analog resistance input (AIR), analog voltage input 0-32V (AIU32), digital high-level output (DOH), and digital low-level output (DOL) test items can be completed. Finally, according to the setting of the tool upper computer program, each port and the input and output types of each port will be tested in turn, and after all the test items are completed, a test report will be automatically generated.

[0023] Taking the analog quantity voltage type 0-32V input (AIU32) of the X01 port as an example, the effective voltage range of the port is 0-32V, when the host computer program of the tool tests the AIU32 port function of the X01, first, the related relay module of the first 8-input 8-output module is switched, the program-controlled power supply for testing the AIU use case is connected to the X01 port, and the program-controlled power supply is adjusted to 0V voltage mode, and is waiting for testing; then, the host computer program communicates with the measured device, and the X01 port is configured to the AIU32 mode (the same port can be configured to multiple port modes, if not, this step is omitted); subsequently, the tool program remotely controls the programmable power supply to output 5V, 20V and 30V voltage, and then the voltage collected by the port of the measured device is fed back to the tool host computer, and the feedback voltage is compared with the 5V, 20V and 30V set by the programmable power supply, if the error is within the error range allowed by the measured device, it is considered that the AIU32 of the port is normal, otherwise, the AIU32 test of the port fails.

[0024] The working principle of the utility model is: first, the host computer controls the devices such as the relay module, the program-controlled power supply and the instrument of the test tool according to the current test item through CAN, RS485 and the like, so that the input or output of the measured device is in the corresponding circuit state, then the host computer communicates with the measured device through CAN communication, the measured device is configured according to the instruction of the host computer, and the output channel is enabled to output or closed to output, so that the current channel of the measured device is normally connected to the tool; finally, the host computer receives the input feedback of the acquisition card, the oscilloscope or the measured device through communication, and compares with the expected value, if consistent, it is considered normal, otherwise, it is not normal, finally the device test is completed, a report is formed, a database is recorded, and it is convenient to review and find problems.

[0025] The system hardware adopts the design idea of modularization, and the overall function is divided into multiple independent and mutually cooperative modules, as shown in Fig. 2 The main modules include 1~n (n<=8) 8-input 8-output unit modules, power supply modules, instrument modules and communication modules, the modules are connected and communicated through well-defined interfaces, and the expandability and maintainability of the system are ensured. As shown in Fig. 2 In the system architecture, 1 8-input 8-output unit module + power supply module + instrument module + communication module is the minimum system, 8-input 8-output units can be selected according to the input and output points of the measured device, and n<=8 in the tool design.
