Monitoring device and monitoring method for real-time voltage of communication chip

Abstract

The invention discloses a monitoring device and a monitoring method for real-time voltage of a communication chip. The monitoring device comprises a master control module, a detection module, a display module, a storage module, a clock module, a communication module and a power source module, wherein the detection module, the display module, the storage module, the clock module, the communication module and the power source module are connected with the master control module. The detection module connected with the to-be-protected communication chip is used for detecting the real-time voltage of the to-be-protected communication chip. The master control module controlled by a single chip microcomputer is used for performing A / D (analog to digital) conversion on collected analog quantity signals and comparing the signals with a preset voltage range, displaying an input voltage value through the display module when the input voltage value is not within the preset range, and sending an analysis result to a monitoring unit through the communication module. By the monitoring device for the real-time voltage, the voltage of the communication chip can be monitored in real time, and warning signals are sent out by the display module and the communication module.

Description

technical field [0001] The invention relates to a communication chip real-time voltage monitoring device and a monitoring method thereof, belonging to the technical field of electric power. Background technique [0002] With the rapid development of the power industry, the scale and capacity of the power grid are increasing day by day, and the types and quantities of power grid equipment are increasing year by year. Among these devices, some are specially used for real-time monitoring of power grid operation values, etc., so that the power grid is in a "knowable" and "controllable" state to ensure reliable operation of the power grid. When a fault occurs on the transmission line, in order to prevent the fault range from expanding, a component is needed to correctly judge the fault state of the transmission line and cause the switch to trip to reduce the fault range. It is called a line protection device, referred to as: line protection. Its basic task: When a fault or abnor...

AI Technical Summary

Problems solved by technology

When the communication chip fails, it is generally a failure that must be resolved immediately. Once it is not handled in time, the background and dispatchers will not be able to obtain effective data from the substation, and will lose monitoring of the substation. This will affect the reliability of power supply at the slightest level, and cause a large-scale interruption of communication in the entire substation. , and even endanger personal safety
