Problems solved by technology

The first method is more reliable, but it requires professionals to operate. The test tool is a computer. If the identification fails once, it is necessary to change the RS485 wiring again and test again.
The second method is more commonly used in the field and requires less tools, but it is inefficient to go back and forth between the upper and lower equipment.

Abstract

The invention discloses a negative control terminal communication interface bidirectional tester based on electricity larceny preventing device. The tester comprises a shell (2). A display (1), a state indicating lamp (3), an operating panel (4) and an RS485 wiring terminals are disposed in front of the shell (2), a battery case (6) is disposed at the bottom of the shell (2), a 220V AC (alternating current) power supply interface (7) is arranged on the side of the shell (2), and an electronic circuit formed by mounting electronic devices on a circuit board is arranged in the shell (2). Reliability of computer test is utilized, the requirements for convenient carrying and simple operation of field test are satisfied, communication failure can be checked easily, and help is provided for communication networks for collecting power application information of power users of national power grid companies.

Description

technical field [0001] The invention relates to a load control terminal communication interface two-way tester for an anti-stealing device based on a load management system, and is an electronic instrument suitable for detecting the RS485 interface communication function of related equipment in the power user information collection system of the State Grid Corporation of China. Background technique [0002] State Grid Corporation of China is in the process of constructing the electricity consumption information collection system for power users. Because of the reliable communication of the RS485 bus, strong anti-interference ability, simple interface circuit and wiring, many devices in the system (such as: concentrators, collectors, meters, etc.) Inter-communication adopts the way of RS485 bus. Because the RS485 interface connection line has the difference between A line and B line, in the actual construction process, due to the wiring of RS485 equipment, A and B lines often...
