基于FPGA的矿用环境采集传输系统设计

Design of Acquisition and Transmission System ofMine Environment Based on FPGA

随着煤炭产业开采从浅层往深层推进,温度、压力和振动等环境条件都时刻需要检测,防止威胁矿下人员安全和财产安全的现象发生,因此一个实时性,稳定性良好的采集传输系统极为重要;针对这一问题,设计了一种基于FPGA多通道、数模混合的采集与实时发送系统;在系统总体设计的基础上,对系统的硬件电路和软件程序设计进行了相关介绍,通过对程序的仿真,验证了采集传输系统设计的可行性;经实物试验验证,采集传输系统可以正确有效地采集和传输5种传感器输出的信号,各信号精度都满足要求,具有一定的工程实用价值。

As the coal mining industry advances from shallow to deep,environmental conditions such as temperature,pressure,and vibration need to be monitored at all times to prevent phenomena that threaten the safety of personnel and property in the mine.Therefore,a real-time,stable collection and transmission system extremely important.To solve this problem,a multi-channel,digital-analog hybrid acquisition and real-time transmission system based on FPGA is designed.On the basis of the overall design of the system,the hardware circuit and software program design of the system are introduced.Through the simulation of the program,the feasibility of the acquisition and transmission system design is verified.It has been verified by physical experiments that the acquisition and transmission system can correctly and effectively collect and transmit the signals output by the five sensors,and the accuracy of each signal meets the requirements,which has certain engineering practical value.
