Hand-held performance monitoring system and monitoring method for electricity consumption information collection system

Abstract

The invention discloses a hand-held performance monitoring system and a monitoring method for an electricity consumption information collection system. The monitoring system includes: a carrier sampling unit, a switch matrix unit, a receiver unit, a spectrum analyzer and an embedded computer unit, and the embedded computer unit It is used to receive and store the vectorized data output by the receiver unit and draw the eye diagram and constellation diagram according to the vectorized data, and receive and store the signal output by the spectrum analyzer and draw the spectrum diagram according to the signal output by the spectrum analyzer . The invention also discloses a monitoring method of a hand-held performance monitoring system used in an electricity consumption information collection system. The present invention can accurately locate the cause of the fault on site, effectively and accurately realize the drawing of frequency spectrum diagram, eye diagram and constellation diagram, and accurately realize the performance monitoring of communication channel, the judgment of protocol consistency and sequence identification; thus, it is simple and fast to assist judgment on the spot Collection terminal communication failure.

Description

technical field [0001] The invention relates to the technical field of electricity consumption information monitoring, in particular to a hand-held performance monitoring system and a monitoring method for an electricity consumption information collection system. Background technique [0002] The electricity consumption information collection system improves the informatization level of electricity consumption management, saves a lot of labor and improves production efficiency. Generally, the electricity consumption information collection system mainly consists of the system master station, public network base station, concentrator, collector, smart meter and so on. Due to factors such as long construction period, multiple technical standards, openness and time-varying nature of the power grid, and lack of optimal communication technology solutions, there are many communication solutions in the existing power consumption information collection system, including wired solutio...

Problems solved by technology

However, after the existing collection terminal equipment has a communication failure during on-site operation, it is usually difficult to determine the cause of the failure on site due to the limited professional skills of the on-site maintenance personnel and the lack of professional maintenance tools. It needs to be dismantled and sent for repair, which takes a lot of time. and manpower, and because some communication failures are caused by on-site electromagnetic environment factors, the on-site situation cannot be reproduced after repairing, so that the fault cannot be accurately located, especially the fault in carrier communication, and the on-site personnel cannot determine the communication capability of the module , and it is impossible to know whether the communication is affected by the electromagnetic environment on site, and the communication failure often still exists after replacing the module

At present, there is a lack of an effective performance monitoring method that can assist in judging the communication failure of the above-mentioned collection terminal on site in the existing technology
