Multi-circuit processing monitoring system for hydraulic turbine temperature signals based on network technologies

Abstract

The present invention discloses a multi-circuit processing monitoring system for turbine temperature signals based on network technologies, which is mainly composed of a master station system and a substation system connected to the master station system through a wireless network; the main station consists of a first single chip microcomputer, a data store, a display, a data processor and a signal processing unit, and a first wireless transmission module; the substation system consists of a second single chip microcomputer, a second wireless transmission module, an air cooler, RS-485 bus and a temperature cruiser A, B and C connected to the second single-chip microcomputer.The signal collected by the substation system of the invention is sent to the master station through the wireless network, which does not need to be connected through the line so that the whole monitoring system is simpler, the monitoring information transmission is quicker and the cost is lower.

Description

technical field [0001] The invention relates to a network technology, specifically, a water turbine temperature signal multi-circuit processing monitoring system based on the network technology. Background technique [0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy, and it belongs to the turbomachinery in fluid machinery. As early as around 100 BC, a prototype of a water turbine appeared in China, which was used to lift irrigation and drive grain processing equipment. Most modern water turbines are installed in hydropower stations to drive generators to generate electricity. However, when the water turbine is under a large load, the temperature of the water turbine will be too high, that is, the temperature of the water turbine driving the engine can be as high as 500°C. If the water turbine works at a high temperature of 500°C for a long time, it will fail. , causing the turbine to fail to drive the genera...
