The invention discloses an underground positioning method. The underground positioning method disclosed by the invention comprises the following steps of: 1, mounting position information collectors, a data transmission device, RFID (radio frequency identification) cards and monitoring equipment; 2, drawing an underground tunnel diagram; 3, sending a wireless signal carrying number of each RFID card by the RFID cards; 4, by virtue of the position information collector, receiving the wireless signal, recording signal intensity of the wireless signal, and adding the signal strength and the number of the RFID card into the received wireless signal, and then sending the wireless signal to the data transmission device; 5, by virtue of the data transmission device, receiving and storing a data packet, and then sending data to the monitoring equipment; and 6, by virtue of the monitoring equipment, positioning according to the data recorded in a database by adopting an adaptive positioning method. According to the method disclosed by the invention, a concrete position of the RFID card is calculated according to a signal strength ratio received by two position information collectors within a known distance, an error caused by wireless signal attenuation in different environments is eliminated, and positioning accuracy is high.
Description
technical field [0001] The invention belongs to the technical field of underground positioning, in particular to an underground positioning method. Background technique [0002] The underground working environment is harsh, the geological conditions are complex, and various harmful gases may be filled at any time, and dangerous accidents such as water seepage and roof fall may also occur at any time. However, the complex environment of the mine determines that not all situations can be detected or predicted by equipment. Therefore, when a dangerous accident occurs in a mine, it is necessary to use an effective underground positioning method to accurately and quickly grasp the exact location and environmental conditions of the underground staff, and communicate information with the trapped personnel in a timely manner, so as to efficiently rescue the trapped personnel and ensure underground work. safety of personnel. [0003] The principle of the existing downhole positionin...
