Research And Design Of Intelligent Monitoring System For Survival Environment Parameters Of Mine Life-saving Capsule

China is rich in coal resources. But because of the deep coal mining, complex geological environment, coalmine accidents occur frequently. Mine life-saving capsule is an effective means of relief after the accident, and the survival environment parameters controlling is the most important part of the capsule system. The intelligent control of the capsule survival environment parameters can be beneficial to save the limited survival resources, can effectively prolong the survival time of the refuge personnel, and can improve the success rate of rescue. However, there are still some problems in survival environment parameters control of capsule system. An intelligent monitoring system for survival environment parameters of mine life-saving capsule based on the theory of single neuron and PID control method is studied and designed in this paper.In terms of the survival environment control of mine rescue capsule, the relevant literatures are mostly to control the single parameter or some parameters in our country. According to the requirement of environmental parameters monitoring system, this paper comprehensively designs its structure and function relatively. It contains the oxygen concentration, harmful gas concentration, temperature, humidity monitoring subsystem. The control scheme of each subsystem is determined, and the corresponding mathematical model is established according to the selected scheme of the subsystem.Capsule survival environment parameter control system has many characteristics, such as time lag, time-varying, nonlinear and coupling. The traditional PID control is difficult to get satisfactory results. A single neuron adaptive PID controller based on the theory of single neuron control is designed in this paper. And that is used in the parameters control subsystem. The decoupling designed in this paper could decouple the parameters that have the coupling relationship between each other. The monitoring system is simulated in the paper with the help of MATLAB. The simulation results compared with the traditional PID control system simulation results confirm the design of monitoring system in this paper has a better control performance.The system selects FPGA as the core controller and uses Verilog HDL language to carry out the hardware and software design. The system consists of data acquisition, intelligent PID controller, output, decoupling, work mode adjustment, time limit estimation and system communication and so on. Finally, the test and experiment carried out by using the prototype of the KJXXX rescue capsule, show that the intelligent monitoring system which designed of living environment parameters can realize the basic functions such as automatic adjustment of environmental parameters, model adjustment, time limit estimation, manual adjustment and so on. And the system has a certain significance and application value.
