Small horizontal water turbine generator set state monitoring device based on radio frequency identification technology

Abstract

The invention relates to a small horizontal water turbine generator set state monitoring device based on the radio frequency identification technology. The device comprises wireless radio frequency identification labels, an edge calculating unit and a monitoring terminal. The wireless radio frequency identification labels are installed on monitoring parts of a small horizontal water turbine generator set and are used for collecting running parameters of all monitoring parts of the set in real time, and the running parameters include the vibration, pressure pulsation, rotating speed, swing andtemperature. The edge calculating unit is used for receiving running parameter data, and the physical quantity corresponding to running parameters are obtained through data processing. The monitoringterminal is used for receiving physical quantity data, and state monitoring is conducted on the small horizontal water turbine generator set based on the physical quantity data. The RFID radio frequency labels are adopted, expansibility is good, effective management is achieved, the real-time performance is high, installation is simple, maintenance is avoided, and monitoring on the running state of the set can be achieved.

Description

Technical field [0001] The invention belongs to the technical field of water conservancy and hydropower, and in particular relates to a state monitoring device for a small horizontal hydroelectric generating set based on radio frequency identification technology. Background technique [0002] At present, large and medium-sized hydropower stations are designed and installed with online status monitoring systems for measuring and monitoring process parameters and stability parameters during unit operation, such as unit speed, power, temperature, vibration, swing, Pressure pulsation, air gap, etc., have become important ways to quickly obtain the operating status of the hydropower unit and find the cause of the fault. [0003] Traditional online monitoring systems are generally wired transmission methods, consisting of a sensor unit, a data acquisition unit and a host computer unit. However, the on-line monitoring device of hydropower unit status is rarely used in small hydropower ge...

However, the online monitoring device for the status of hydropower units is rarely used in small hydropower units

For small hydropower units, the number of operation and maintenance personnel and technical level are lower than those of medium-sized units, and the status parameters of the equipment in operation cannot be obtained in real time, which is not conducive to the safe and stable operation of the unit, and also increases the labor intensity of operation and maintenance personnel
