Embodiment 1

[0020] Such as figure 1 , figure 2 As shown, this embodiment provides a system for monitoring characteristic signals of state of plant equipment, which is applied to a plant with a large number of equipment, such as a power plant plant. In this embodiment, the state characteristic signal monitoring system of plant equipment is described by taking the state characteristic signal monitoring of the rotating machinery equipment (referring to pump sets, fans, diesel generators, steam turbine generators and other equipment) of the whole nuclear power plant as an example. The plant equipment status characteristic signal monitoring system includes a characteristic signal sensing unit 1, a signal transmitter, a PLC controller 31, a DCS information collection cabinet 5, and a monitoring platform 6 in the main control room. The characteristic signal sensing unit 1 is used to collect various characteristic signals of the state of the plant equipment. The signal transmitter is connected...

Abstract

The invention discloses a plant equipment state characteristic signal monitoring system. The system comprises a characteristic signal sensing unit, a signal transmitter, a PLC, a DCS information acquisition cabinet and a main control room monitoring platform. The characteristic signal sensing unit is used for collecting various characteristic signals of the plant equipment state. The signal transmitter is respectively connected with the characteristic signal sensing unit and the PLC, and is used for receiving the characteristic signal acquired by the characteristic signal sensing unit, converting the characteristic signal into a physical quantity characteristic signal and sending the physical quantity characteristic signal to the PLC through a communication protocol. The PLC is connected with the DCS information acquisition cabinet and is used for sorting the received signals and sending the sorted signals to the DCS information acquisition cabinet. The DCS information acquisition cabinet is connected with the main control room monitoring platform and is used for transmitting the sorted signals to the main control room monitoring platform. According to the system, DCS interface resources can be saved, so that the hardware cost and the construction difficulty of factory building are reduced.

Description

technical field [0001] The invention belongs to the technical field of equipment detection, and in particular relates to a monitoring system for state characteristic signals of plant equipment. Background technique [0002] The rotating machinery equipment of the nuclear power plant mainly refers to the rotating machinery equipment such as pumps, fans, diesel generators, and steam turbine generators. The detection technology can be used to monitor the state characteristic signals of the rotating machinery equipment. Among them, the state characteristic signals mainly include vibration signals, Key phase signal, speed signal, shaft temperature signal, acoustic emission signal, etc. Usually, manufacturers of nuclear power plant pump sets and fan rotating machinery equipment independently purchase vibration, key phase and speed sensors and supply them as a whole with the mechanical equipment. In the delivery mode, there are large differences in sensor brands, types, interfaces,...
