Remote-monitoring frequency-conversion intelligent water supply system and method based on power line carrier communication

Abstract

The present invention discloses a remote-monitoring frequency-conversion intelligent water supply system and method based on power line carrier communication. According to the system, an intelligent frequency-conversion water supply controller is connected with a power line carrier communication circuit A through a 232 or 485 communication port, the power line carrier communication circuit A is connected with a power line carrier communication circuit B through a power line, and the power line carrier communication circuit B is installed at a place with radio signals and is connected and communicates with a monitoring center through a power line. Through power line carrier communication, remote monitoring and real-time data remote transmission of the frequency-conversion intelligent water supply system on occasions with weak radio signals and without radio signals are realized, an automatic management level of the system is raised, equipment maintenance costs are lowered, the problem of remote monitoring of radio signal blind areas is effectively solved, and excellent social and economic benefits are generated.

Description

technical field [0001] The invention relates to a remote monitoring frequency conversion intelligent water supply system and method based on power line carrier communication, and belongs to the technical field of remote monitoring of water supply systems. Background technique [0002] Frequency conversion intelligent water supply system has been widely used in water supply for high-rise buildings. Most of its main equipment is installed in the basement of the building. In order to facilitate the management personnel to grasp the operation status of the equipment in real time, find out the faults in time, and quickly deal with them to ensure the safety of water. At present, some frequency conversion intelligent water supply equipment is equipped with remote monitoring function based on GPRS. However, the existing intelligent frequency conversion water supply system has the following shortcomings: because the equipment is installed in the basement, the radio signal is unstable,...
