Special RTU (remote terminal unit) for gas turbine based on Loongson chip

Abstract

The invention discloses a gas turbine special RTU remote terminal device based on a Loongson chip, which comprises a mounting seat, an RTU device body is mounted in the mounting seat, two sliding cylinders are mounted on the top of the mounting seat, sliding rods are slidably connected in the two sliding cylinders, one end of each sliding rod is provided with a limiting block, and the other end of each sliding rod is provided with a limiting block. A spring sleeves the sliding rod, a first air bag is installed on the inner bottom surface of the mounting base, second air bags are installed on the inner left side wall and the inner right side wall of the mounting base, connecting pipes are installed on the two second air bags, and the two second air bags make contact with the left side face and the right side face of the RTU device body correspondingly. The RTU device body is pressed downwards, so that the two second air bags can clamp the RTU device body, meanwhile, the RTU device body cannot move upwards through the limiting blocks, then the RTU device body is fixed in the mounting base, and the first air bag and the second air bags can provide a certain damping effect for the RTU device body.

Description

technical field [0001] The invention relates to the field of remote terminal control, in particular to an RTU remote terminal device dedicated to gas turbines based on a Godson chip. Background technique [0002] The gas turbine is an internal combustion power machine that uses continuous flowing gas as the working medium to drive the impeller to rotate at high speed, and converts the energy of the fuel into useful work. It is a rotary impeller heat engine. The English full name of the RTU device is RemoteTerminal Unit, and the Chinese full name is the remote terminal control system. It is generally used to monitor and control on-site signals, industrial equipment operation, and gas usage. Because it is used remotely, it has a remote communication module. [0003] However, the existing RTU remote terminal device dedicated to gas turbines based on the Godson chip has the following shortcomings in use: [0004] First, the installation method of multiple screws is often used, ...

AI Technical Summary

Problems solved by technology

[0004]First, multiple screws are often used for installation, the installation steps are cumbersome, and it is not conducive to later removal and replacement;

[0005] Second, the lack of cooling function, can not effectively cool down the RTU remote terminal device, resulting in reduced service life of the RTU remote terminal device
