[0002] At present, in the construction process of the electricity consumption information collection system, there are problems that the original electricity consumption information collection terminals have mismatching functions and requirements and single communication methods in some areas, which cannot meet the differentiated needs of various regions. In addition, the types of terminals There are many, and the requirements for manufacturing enterprises are relatively high, which restricts the large-scale production of production enterprises; in 2014, the State Grid organized a modular terminal pre-research project, and designed the power consumption information collection terminal into a module structure with multiple independent functions According to the actual needs of each region, the corresponding module combination can be prepared to form terminals with different functions to meet the market's diverse needs for power consumption information collection terminals. Based on the above reasons, intelligent terminals with modular design came into being. After several years of development and improvement, this type of smart terminal has gradually entered the stage of mass production

[0003] At present, the production test method for this type of intelligent terminal is: conduct communication test and load test for each interface respectively, first connect the communication module to the interface, test whether the communication of the interface is normal, and then connect the load to the interface to 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; The production testing of smart terminals mostly relies on manual testing, which requires testing of all module interfaces. The testing efficiency is low and the time required is long. At the same time, manual testing is inconvenient for a single person to perform load testing during transient load testing. The adjustment requires the cooperation of someone, and the test data cannot be stored in real time, which heavily depends on the technical level and responsibility of the testers. During mass production, the demand for testers is large and the labor cost is relatively high; in view of this, there is an urgent need A device for conveniently detecting the interface of an intelligent terminal
