Abstract

The invention discloses a 485 communication detection system. A 485 sending end is controlled by an upper computer to send an original waveform; the original waveform is transmitted to a receiving end485 device through an electronic load; a voltage waveform detection device detects an output waveform passing through the electronic load and transmits an output waveform to a main control module; the main control module calculates 485 loading capacity according to the waveform data, wherein a model and identification and detection on the loading capacity are not needed, thereby simplifying the detection scheme, improving the detection efficiency, and solving the technical problems that an existing 485 communication detection scheme needs to establish the model and needs corresponding identification and detection on the loading capacity, the process is complex, and consumed time is long.

Description

technical field [0001] This application relates to the technical field of 485 communication, in particular to a 485 communication detection system. Background technique [0002] RS485 is a standard defining the electrical characteristics of drivers and receivers in a balanced digital multipoint system, defined by the Telecommunications Industry Association and the Electronic Industries Alliance. At present, the smart meters in the power grid use the RS485 communication interface to communicate. As an important communication unit of the smart meter, the rationality and reliability of the RS485 interface design scheme affect the performance of the smart meter. [0003] The patent application with the patent application number 201520755058.7 discloses a design scheme identification and load capacity detection device for the RS485 interface of an electric energy meter. The scheme first establishes three internal 485 connection schemes of the electric meter and a load capacity ju...
