Mining rail transport vehicle wireless communication control system and control method

Abstract

The invention provides a mining rail transport vehicle wireless communication control system and a control method. The system comprises a leakage communication device, the leakage communication device comprises a leakage cable arranged along a rail transport roadway, one end of the leakage cable is connected to a base station, and the base station is in intercommunication connection with main control equipment; a wireless vehicle-mounted control device comprises a wireless vehicle-mounted control box, a signal receiving and transmitting antenna is arranged on the wireless vehicle-mounted control box, the signal receiving and transmitting antenna is used for receiving signals of the leakage cable or transmitting the signals to the leakage cable, and an encoder used for measuring the speed of the transport vehicle is connected to the wireless vehicle-mounted control box; and the wireless vehicle-mounted control box is electrically connected with an oil pressure sensor arranged on the transport vehicle and a pilot electromagnetic valve arranged on a brake loop of the transport vehicle. The invention further provides a control method of the control system. The leakage communication device can synchronously transmit signals of oil pressure, speed, control instructions and the like in real time during communication talkback, and signal transmission is clear, complete and accurate.

Description

technical field [0001] The invention belongs to the technical field of communication control of rail transport vehicles for mines, and in particular relates to a wireless communication control system and control method for rail transport vehicles for mines, which are used for wireless communication transmission and control in underground mines. Background technique [0002] Mine underground rail transport vehicles run back and forth in the rail transport lane. In order to ensure the safety of operation, it is necessary to detect, control and protect their operating conditions. The control technology currently used uses analog leakage as the main communication medium. The operator uses a handheld device for operation and control, the vehicle-mounted control device uses a flameproof control box, and the vehicle speed detection adopts a centrifugal mechanical method. [0003] There are some problems in the actual application of the communication method of the prior art: [000...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide a wireless communication control system and control method for rail transport vehicles used in mines, which solves the problem that the oil pressure signal and the oil pressure signal of the transport vehicle cannot be transmitted in real time in the prior art that uses the analog leakage method as the main communication medium for control. The speed signal, the on-board braking system cannot be effectively communicated with the main control equipment, etc.
