Device for intelligently selecting and inspecting onsite bus of electric power meter

Abstract

The invention provides a device for intelligently selecting and inspecting an onsite bus of an electric power meter, and the device comprises a power supply, an MCU control circuit, an RS485 input circuit, an RS485 output circuit, and a fault indication LED array. The output end of the RS485 input circuit is connected with the input end of the MCU control circuit, and an output end of the MCU control circuit is connected with the RS485 output circuit. The power supply is connected with the RS485 input circuit and the MCU control circuit. The MCU control circuit is connected with the fault indication LED array. Through the grouped analysis of intelligent units, the device detects the data of any intelligent equipment in a group, and enables the data to be gathered and transmitted in a packaged manner, thereby achieving the monitoring of a local equipment communication network, achieving the timely finding of a fault defect of equipment, indicating the position of a fault unit in a mode of sound light alarm, and bringing convenience to an operation and maintenance worker for inspecting the fault equipment and processing the fault defect timely.

Description

technical field [0001] The invention belongs to the field of electric power detection, in particular to a field bus intelligent selection and detection device for electric power meters. Background technique [0002] The field bus intelligent selection and detection device of the power meter is mainly used in various low-voltage equipment in the power system. In the low-voltage network, there are generally many low-voltage equipment, and the various intelligent units are often connected in parallel through the data bus. If any Anomalies in nodes, such as communication interruptions, data anomalies, etc., will affect the working status of the entire system, and anomalies will be reported in the background monitoring, but it is very troublesome to find, because it is difficult to Quickly lock the fault point, there is a problem that the staff cannot handle and solve the fault defect in time. Contents of the invention [0003] The problem to be solved by the present invention...
