[Abstract]:As surface minerals are exploited in large quantities, the mining industry continues to develop deep underground. Due to the poor working environment in the underground, it will not only cause personal harm to the staff, but also seriously interfere with the judgment and execution of the operators of the underground trackless equipment, resulting in accidents occurring from time to time, and at the same time, the production efficiency will also be affected. Working safety of underground trackless equipment has become an important factor restricting the development of mining industry. In order to solve the safety problem of underground trackless equipment, a CSS positioning system based on SDS-TWR algorithm is designed to locate the distance between trackless equipment, workers and other equipments in real time. Feedback distance status information to driver. First of all, combining the particularity of underground working environment and the working characteristics of trackless equipment in underground, this paper analyzes the functional requirements and performance indexes of the system, and then compares the status quo, characteristics and application scope of the commonly used positioning technologies such as Wi-Fi Field-RFID-ZigBee-UWBBCSS, etc. Compared with other aspects, such as economy, reliability, positioning precision and applicability of underground environment, the CSS positioning technology suitable for underground environment is put forward. Based on Nanotron nanoPAN5375 RF module, the hardware of CSS positioning system is designed. Secondly, this paper analyzes the factors that affect the positioning effect in downhole environment, and puts forward an extended Kalman filter method to improve the positioning accuracy, aiming at the problem of the positive error of ranging in the downhole environment. A piecewise least square interpolation algorithm is proposed to improve the real-time stability of the location system. Finally, the upper computer software is written on QT platform to process and analyze the positioning data, and feedback the distance monitoring information of trackless equipment to the driver in real time. The system is tested in ideal environment and simulated underground roadway environment. The test results are analyzed by Matlab, and it is verified that the moving positioning system of underground trackless equipment can be used to locate the moving nodes in the downhole in real time. The precision meets the demand.
