Mine underground vehicle speed measuring device

Abstract

The invention provides a mine underground vehicle speed measuring device which comprises a shell and is characterized in that a microcontroller, a power supply, WIFI, an acceleration sensor, a clock,an EEPROM memory and a buzzer are arranged in the shell, the microcontroller is electrically connected with the power supply, the acceleration sensor, the WIFI, the buzzer, the clock and the EEPROM memory, and the power supply is connected with the acceleration sensor, the EEPROM memory, the clock and the buzzer. After speed data are obtained through the acceleration sensor, the speed data are sent to the microcontroller, signals are sent to the central controller through the WIFI by the microcontroller, and meanwhile the signals are sent to the buzzer to give an alarm, sent to the EEPROM, stored in the clock and timed so as to reserve the position and the speed data of the time point. Underground overspeed alarm and unmanned automatic acquisition and transmission of speed data are realized, the later operation and maintenance workload is reduced, and the operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to a speed measuring device for underground vehicles in mines, belonging to the technical field of microelectronics in electronic information. Background technique [0002] In the process of mine production, safety production is more important than everything else. Among them, the risk of vehicle injury is the most prominent. In order to ensure the safety of underground production operators, a vehicle speed measuring device must be installed on the vehicle going down the mine. The current test method is to install a magnet on the bearing of the vehicle, and install a Hall sensor near the magnet. The Hall sensor continuously detects the pulse signal to calculate the vehicle speed. Due to the complexity of the underground roadway, the road condition is not good, the vehicle body shakes a lot, it is prone to speed measurement error data, and the Hall sensor is also easy to be damaged. In addition, there are many types of vehicles, an...
