Background technique

At present, in the process of building the electricity consumption information collection system, there are problems with the original electricity consumption information collection terminals in some areas, such as mismatch between functions and demands and single communication mode, which cannot meet the differentiated demands of various regions. In addition, there are many types of terminals, which have high requirements for manufacturing enterprises, restricting the large-scale production of manufacturing enterprises. In 2014, State Grid organized a modular terminal pre-research project, designed the electricity consumption information collection terminal into a plurality of independent functional module structures, and configured corresponding module combinations according to the actual needs of various regions, which can form terminals with different functions to meet the market's diversified demands for electricity consumption information collection terminals. Based on the above reasons, modular intelligent terminals came into being. After development and improvement in recent years, such intelligent terminals have gradually entered the mass production stage.

At present, the method for production testing of such intelligent terminals is: perform communication test and load test on each interface respectively, first connect the communication module to the interface to test whether the interface communication is normal, then connect the load to the interface, adjust the load size, use a multimeter to measure whether the output current and voltage reach the specified standard, and finally use an oscilloscope to measure whether the voltage ripple reaches the specified standard; but since such intelligent terminals adopt modular design and have multiple module interfaces, and currently the production test of such intelligent terminals mostly relies on manual testing, all module interfaces need to be tested, the test efficiency is low, and the time required is long. At the same time, it is inconvenient for a single person to adjust the load during transient load testing, and someone needs to cooperate before it can be carried out. In addition, the detection data cannot be stored in real time, and it is heavily dependent on the technical level and sense of responsibility of the tester. During mass production, a large number of testers are required, and the labor cost is relatively high; in view of this, there is an urgent need for a device that is convenient for detecting the interface of the intelligent terminal.
