Design And Implementation Of Safety Monitoring System For Trackless Rubber-tyred Vehicles In Mines

Mining trackless rubber-tyred truck is an important equipment for the auxiliary transportation system in coal mines.It undertakes the task of underground production materials and personnel transportation.Due to the harsh working environment in coal mines,heavy transportation tasks of trackless rubber-tired vehicles,and frequent use,as well as the existing safety devices have problems such as fewer types of vehicle condition parameter monitoring,inaccurate vehicle positioning,and high noise of monitoring parameter data,etc.,resulting in accidents.Occurs frequently.In view of the above problems,this paper analyzes the shortcomings of the current trackless rubber-tired vehicle safety monitoring work,and proposes a trackless rubber-tyred vehicle safety monitoring system with high positioning accuracy,comprehensive functions and stable performance to ensure the safety of the vehicle.run.The accurate positioning and scheduling of vehicles can ensure the safe operation of trackless rubber-tired vehicles and improve transportation efficiency.This paper analyzes several commonly used positioning algorithms,and combines RSS1 and TOF ranging and positioning algorithms to propose a hybrid ranging and positioning algorithm based on on-site Bluetooth devices.On the basis of theoretical analysis,this paper designs a safety monitoring system for trackless rubber-tyred vehicles.The system consists of two parts:the upper computer and the terminal device.The upper computer part is mainly used for remote viewing of vehicle condition parameters,and the terminal device part is mainly used to monitor the cooling water temperature,oil temperature,vehicle speed,gas volume concentration,and exhaust gas of the trackless rubber tire.Collection and display of parameters such as temperature.At the same time,the reversing anti-collision device is one of the important measures to ensure the safe operation of the vehicle.This paper analyzes the performance characteristics of different ranging sensors,selects multiple ultrasonic ranging sensors as ranging instruments,and monitors blind spots,alarm methods and The ultrasonic interference problem is analyzed and designed in detail,and an omnidirectional and high-precision reversing anti-collision device based on multiple ultrasonic ranging sensors working together without interference is proposed.Finally,on the premise of completing the overall function design of the system,the system power supply intrinsic safety,circuit anti-interference,and fault monitoring are analyzed and designed.According to the above design,the host computer in this paper is based on the Android Studio development platform,and the terminal device is based on the FPGA controller and various peripheral devices.The system is developed and the laboratory test is completed.The test results show that the safety monitoring system for the trackless rubber-tyred vehicle proposed in this paper is feasible and effective,and the real-time monitoring of the trackless rubber-tyred vehicle is realized.The research results have certain reference significance for theoretical research in the same industry,and also have certain practical and promotion value.
