[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] It should be noted that this application is made based on the inventor's understanding and research of the following issues:

[0032] PLC-IOTPLC-IOT communication module detection device in related technology Figure 1As shown, PC 400 (Personal Computer) communicates with the test base plate 10 through a USB (Universal Serial Bus) port, and PC 400 has a host computer test software. The test base plate 10 and the IoT communication module 200 to be tested use a service serial port for data exchange, such as USART (Universal Synchronous / Asynchronous Receiver / Transmitter) or RS485, and the test base plate 10 is used to perform hardware testing on the IoT communication module 200 to be tested. The test base plate 10 is plugged with a test companion communication module 300, and the test companion communication module 300 can be a single-phase IoT communication module, a three-phase IoT communication module, or a concentrator IoT communication module. The test process and control center in the related art are the host computer test software, the PC 400 end is the main control center and data storage center, and the PC 400 end is responsible for reading the detection scheme script file and the detection process control, so as to complete the detection of a single IoT communication module.

[0033] Therefore, the detection device in the related art only supports the test of a single IoT communication module, and the detection efficiency is low. Moreover, because one PC 400 detects one IoT communication module, when multiple IoT communication modules need to be detected, each PC 400 needs to configure the detection scheme and detection parameters, so the operation is difficult, the cost is high, and it takes a long time to modify the detection scheme. In addition, because each PC 400 stores the detection results and detection logs of the corresponding IoT communication module, the detection results and detection logs cannot be centrally managed, and the maintenance workload is large.

[0034] Based on this, an embodiment of the utility model provides a PLC-IOT communication module detection device and detection system. After receiving the detection plan, the control unit can send the detection plan to multiple test boards at the same time, so that multiple IoT communication modules to be tested can be detected at the same time, thereby improving the detection efficiency.

[0035] The following describes the PLC-IOT communication module detection device and detection system of the embodiment of the utility model with reference to the accompanying drawings.

When the control unit 20 receives the pre-configured detection scheme, it can determine which test baseboards 10 correspond to the IoT communication modules 200 to be tested that need to be tested according to the detection scheme, and then send the detection scheme to the corresponding test baseboard 10, and the corresponding test baseboard 10 detects the corresponding IoT communication modules 200 to be tested according to the detection items in the detection scheme.

[0039] In an optional implementation, the control unit 20 may be a control chip 101 , and a maximum of 10 test baseboards 10 may be provided in the PLC-IOT communication module detection device 100 .

[0047] Specifically, because the IoT communication module 200 to be tested and the corresponding accompanying communication module 300 need to communicate, the IoT communication module 200 to be tested and the corresponding accompanying communication module 300 need to be different types of communication modules, so that the IoT communication module 200 to be tested and the corresponding accompanying communication module 300 can be successfully networked. Therefore, when the IoT communication module 200 to be tested is a single-phase IoT module or a three-phase IoT module, the corresponding accompanying communication module 300 is a concentrator IoT module; when the IoT communication module 200 to be tested is a concentrator IoT module, the corresponding accompanying communication module 300 is a single-phase IoT module or a three-phase IoT module.

The voltage conversion module 102 includes a DC-DC (direct current-direct current) switching regulator chip (not shown), and the DC power supply is converted by the DC-DC switching regulator chip to generate a power supply for the control chip 101, thereby supplying power to the control chip 101 and the peripheral circuit. For example, assuming that the voltage of the DC power supply is 24V, the voltage conversion module 102 steps down the DC power supply to generate multiple power supplies, and the voltages of the multiple power supplies are 12V, 5V and 3.3V respectively, to supply power to the control chip 101 and the peripheral circuit. The voltage acquisition module 103 includes 6 ADC (Analog-to-Digital Converter) voltage acquisition submodules (not shown), each ADC voltage acquisition submodule supports a maximum of 24V voltage acquisition, and each ADC voltage acquisition submodule contacts the test point (e.g., 12V, 3.3V, 1.2V) of the corresponding IoT communication module 200 to be tested through a probe to collect the test point voltage of the corresponding IoT communication module 200 to be tested. The accompanying test communication module 300 can be directly inserted into the accompanying test module interface 104. The adapter interface 106 is connected to the weak current interface of the corresponding IoT communication module 200 to be tested through the adapter 30, and the weak current interface includes GPIO (General Purpose Input / Output), USART and network port, and the adapter 30 is a communication conversion unit between the test base plate 10 and the corresponding IoT communication module 200 to be tested. The current acquisition module 105 acquires the current of the corresponding IoT communication module 200 to be tested, and obtains the current sampling value. According to the current sampling value, the static power consumption and dynamic power consumption of the corresponding IoT communication module 200 to be tested can be calculated. The control chip 101 is connected to the control unit 20 through the communication interface 107 and the hardware interface 108. The communication interface 107 is used to perform TCP (Transmission Control Protocol) communication with the control unit 20. The hardware interface 108 can be a USB interface.
