High-speed train operation natural environment monitoring device based on ZigBee

Abstract

The invention discloses a high-speed train operation natural environment monitoring device based on ZigBee. The device comprises a ZigBee terminal, a ZigBee coordinator, a data transmission module, ascheduling management module and an intelligent decision-making module, the RF module is wirelessly connected with a ZigBee terminal; the signal amplification module comprises a single-chip microcomputer, a voltage input module, a signal controllable amplifier, a voltage output module, an AD conversion module and a DA conversion module, the single-chip microcomputer is connected with the DA conversion module, and the input end of the signal controllable amplifier is connected with the voltage input module. In the voltage signal amplification part, the voltage signal is amplified by using a method of setting gain by software, so that the traditional mode of manually adjusting an amplification gear is changed; an intelligent decision-making unit is additionally arranged on an existing natural disaster monitoring device, the intelligent decision-making unit is composed of a data fusion model, the collected data can be fused, and then the safety evaluation level of the train operation natural environment is obtained and analyzed by dispatching commanders.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a ZigBee-based high-speed train operating natural environment monitoring device. Background technique [0002] High-speed trains, also known as high-speed trains, refer to trains that can run continuously at high speeds, and the maximum speed generally reaches more than 200km / h. High-speed train is a modern high-speed transportation tool, which is a concentrated expression of the top science and technology of trains, which can greatly increase the speed of train travel and improve the efficiency of train transportation. High-speed trains are fast, comfortable, stable, safe, energy-saving and environmentally friendly, and are very popular among contemporary people. All countries in the world strongly support the use of new high-speed trains to meet the growing travel needs.

AI Technical Summary

Problems solved by technology

[0003] The main disadvantages of high-speed trains are: the cost of the whole vehicle is high, the maintenance cost is high, the technology is extremely difficult, the basic dependence on electricity, and the strict requirements on the railway system. With the rapid development of my country's railway transportation industry, the total mileage of my country's high-speed railways has exceeded 22,000 kilometers

The high-speed railway has a long operating mileage, and the region and climate it passes are complex and changeable. Knowing the natural environment of the high-speed railway operation in a timely manner can provide alarm information for dispatching command and maintenance management, which can effectively prevent natural disasters along the line from affecting the safety of high-speed railway traffic and the line; Because high-speed trains have very strict requirements on the railway system, if there is a problem in the railway system, it will directly affect the operation of the high-speed train. Therefore, the environmental monitoring of the railway system along the high-speed train is extremely important. At present, the existing natural environment monitoring devices along the railway are generally The wired monitoring station method is used, that is, the connection between the monitoring terminals is connected by buried wires. However, this method has limitations such as troublesome wiring, narrow monitoring range, single monitoring data, poor flexibility of monitoring terminals, and high maintenance costs. In addition, This device can only complete the acquisition of environmental data, but cannot complete the analysis and processing of the data in the later stage, so the environmental safety assessment level along the railway line cannot be obtained, and the management and service level is low. In view of the above problems, the present invention is specially designed. solve
