Rail transit vehicle POST automatic control system

Abstract

The invention relates to the technical field of rail transit, and discloses a rail transit vehicle POST automatic control system which comprises a POST main control module and a constant voltage module. The POST main control module is connected with an instrument module, and an instrument in the instrument module adopts a two-component food-grade heat-resistant silica gel casting one-step molding electric appliance integrated modular design; and the POST main control module comprises a switching power supply, an anti-corrosion electrode, a magnetic induction floater, a heat dissipation module and a waterproof module, the switching power supply is connected with an oscillating circuit, and the oscillating circuit is connected with a signal comparison module. When a train runs at a high speed, a condensation phenomenon caused by a heating temperature difference of electric devices is eradicated, the components are ensured to be prevented from being damaged by wind, sand, stone and the like, certain elasticity is achieved, waterproof performance is good, a liquid level in an operation distribution water tank can be accurately detected under the vibration condition, and stability is good.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a POST automatic control system for rail transit vehicles. Background technique [0002] Rail transit refers to a type of vehicle or transportation system that operating vehicles need to run on specific tracks. The most typical rail transit is the EMU system composed of traditional trains and standard EMUs. With the diversified development of train and railway technology , Rail transit presents more and more types, not only in long-distance land transportation, but also widely used in short- and medium-distance urban public transportation. [0003] In the operation of rail transit vehicles, it is generally necessary to detect the water level of the water tank in order to replenish it in time. However, due to the inertia of the train, the water in the tank is in a fluctuating state, causing the quantity display to be untrue and unstable, resulting in a virtual reflection of t...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the present invention provides a POST automatic control system for rail transit vehicles, mainly to solve the problem that the water in the box body is in a fluctuating state due to the inertia or slope of the train, causing the quantity display to be untrue and unstable, and causing the virtual reflection of the comprehensive use of the train state, and the waterproof and dustproof performance of components is not good enough to meet people's requirements
