Mining inclined roadway conveyance monitoring system and method based on radio-frequency technique

Abstract

The invention discloses a mining inclined roadway conveyance monitoring system based on the radio-frequency technique. According to the mining inclined roadway conveyance monitoring system based on the radio-frequency technique, information of a person positioning card which is carried by a person is recognized and read by a controller through a reader; when the controller detects that a person who affects safe operation of a winch exists in a roadway or no specific person exists at the control position of the winch, the winch is forbidden to be started or operation of the winch is stopped through an output unit. A mining inclined roadway conveyance monitoring method based on the radio-frequency technique comprises the steps that (a) information of the positioning card is judged, (b) whether the trinity is effective or not is judged, (c) whether all confirmation is conducted or not is judged, (d) whether a winch driver exists or not is judged, (e) the winch is started, (f) a prompt area is judged, (g) a forbidden area is judged, (h) whether the driver leaves away from the working position is judged. According to the mining inclined roadway conveyance monitoring system and method based on the radio-frequency technique, the person information in the roadway is judged by means of the person positioning card, and the defects that the real-time performance is poor, the workload is heavy when people in the roadway are detected manually, and data are not accurate when people in the roadway are detected through an infrared sensor are overcome.

Description

technical field [0001] The present invention relates to a mining inclined roadway transportation monitoring system and method based on radio frequency technology. "Radio Frequency Technology-Based Mine Inclined Roadway Transportation Monitoring System and Method. Background technique [0002] According to the requirements of "Code for Use and Management of Coal Mine Underground Workers Management System" (AQ1048-2007): All personnel entering the mine must carry identification cards (or wireless communication devices with positioning functions). Coal mine transportation management system requires: "Pedestrians must not drive, vehicles must not pass pedestrians" in the winch lane, that is, in winch transportation, vehicles and pedestrians are not allowed to drive at the same time. At present, the solutions for this situation in coal mines are as follows: the first is to manually check the personnel information in the roadway. The second is to detect personnel information in ...

AI Technical Summary

Problems solved by technology

Due to the relatively random behavior of personnel, when multiple people pass by the sensor side by side and enter the roadway, the sensor will only record one person passing through after receiving a signal, and the controller will record the information of one person, so the recorded information will be inaccurate

When the goods pass through the sensor, the sensor will output a response, and the controller will receive the signal and count, and the count will also be inaccurate

Therefore, this method cannot accurately obtain the information status of personnel in the roadway, and cannot fundamentally realize "pedestrians must not drive, and vehicles must not pass pedestrians"
