Problems solved by technology

[0003] However, the existing UWB does not support the communication frame filtering function on the hardware. When the system contains more ranging tag nodes to initiate ranging, it is easy to cause data flow collision interference in communication, causing ranging communication abnormalities or ranging The result is incorrect, causing the positioning to fail

Abstract

The invention discloses an underground locomotive ranging and positioning method and system based on UWB ultra-wideband wireless communication, and the method comprises the steps: transmitting a querydata packet to a communication base station in a ranging region, and obtaining ranging parameters issued by the communication base station, wherein the ranging parameters comprise a ranging permission channel, a ranging time slot, a ranging waiting time delay, and a ranging base station ID; sending a ranging data packet to a ranging base station in a ranging time slot by using the ranging permission channel to obtain a ranging distance between the UWB label and the ranging base station; and uploading the distance measurement distance to a ground server for position calculation to obtain the offset of the UWB label deviating from the track so as to obtain the current locomotive position. According to the underground locomotive ranging and positioning method, conflicts in the UWB label distance measurement process are avoided, so that positioning calculation is more real-time and more accurate.

Description

technical field [0001] The present invention relates to the field of ranging and positioning mine locomotives, in particular to a method and system for ranging and positioning underground locomotives of UWB ultra-wideband wireless communication. Background technique [0002] The underground mine has a special geographical environment, the roadway is long and narrow, and radio signal transmission attenuation is serious. GPS satellite positioning signals cannot reach underground coal mines. However, positioning technologies such as RFID, ultrasonic, and Bluetooth have short communication distances and limited positioning accuracy. At the sub-meter level, the error is relatively large, and it is difficult to meet the needs of coal mine accident rescue, transportation, and electromechanical accident prevention and control. UWB technology is a wireless communication technology based on nanosecond-level ultra-narrow pulses. This technology has the characteristics of strong anti-in...
