With the advancement of the construction of the power Internet of Things,a large amount of intelligent terminal devices and data need to be connected to the Internet of Things platform.Due to the standardization and intelligence of the software and hardware of intelligent terminal devices,the low convenience of device assembly and maintenance,as well as the uneven level of construction skills and the lack of specialized debugging tools,the current installation and debugging quality and efficiency are low,affecting the practical application of the power internet of things.For this purpose,the on site debugging requirements of distribution IoT intelligent terminals were studied,and on site simulation cloud testing technology and signal injection methods for different types of terminals were proposed.Based on this,automatic closed loop debugging of“end,edge,and cloud”was achieved in on site debugging.For the on site debugging of the primary and secondary fusion DTU/FTU,an independent electromagnetic/electronic signal output channel design and high precision output technology was proposed,and fully automatic closed loop debugging was achieved in conjunction with the simulated distribution main station.The paper also elaborates the design of software architecture of debugging tool and the design of automatic test flow of intelligent terminal.The debugging tool based on this technology was tested on site and good results were shown.
