Embodiment Construction
[0028] The present invention is illustrated below in conjunction with the accompanying drawings.
[0029] Such as figure 1 As shown, an active collision avoidance method for mining electric locomotive based on risk factor,
[0030] Including: sensors, central processing units and actuators;
[0031] The sensor includes a photoelectric encoder disc sensor and an infrared distance sensor;
[0032] The sensor collects information, and transmits the collected information to the central processor unit for processing, and the central processor unit drives the corresponding actuator to perform actions after processing;
[0033] Specific steps:
[0034] Step 1: Collect the current motion information of the electric locomotive, including running speed, distance from obstacles in front, time, and obtain running status data;
[0035] Step 2: According to the collected data on the running status of the electric locomotive, calculate the risk factor of the possible collision accident o...

The invention discloses an initiative collision avoidance method of a mining electric locomotive based on a danger coefficient, and belongs to a mining electric locomotive safety auxiliary brake method. The method comprises the steps of acquiring current motion information of an electric locomotive, and acquiring operating state data; calculating the danger coefficient for the electric locomotive to have the collision accident according to the acquired operating state data of the locomotive, and calculating a danger grade; transmitting acoustic-optic alarming signals of different grades and corresponding brake signals according to the danger grade; repeatedly acquiring the operating state data of the electric locomotive. The initiative collision avoidance method is reasonable in design, the needed brake safety distance and danger coefficient can be calculated according to the current running speed and following distance, the alarming and brake in different grades can be realized, the rear-end or head-on crash probability of the electric locomotive can be greatly reduced, safeguard can be provided for the underground safety production, the control priority of a driver can be guaranteed, and the method is suitable for being popularized in coal mine well.
Description
technical field [0001] The invention belongs to the field of safety auxiliary braking methods for mine electric locomotives, in particular to an active collision avoidance method for mine electric locomotives based on a risk factor. Background technique [0002] With the vigorous development of the coal industry, the underground transportation tasks closely related to the production of raw coal in coal mines are becoming increasingly heavy. Generally, the speed of driving is increased, or the number of transportation vehicles and number of vehicles are increased. However, this also brings many unfavorable factors and potential safety hazards, especially in the case of irresponsibility, dislocation of the switch, mistakenly switching the switch, and the driver's inattention, slow response, fatigue, drowsiness, or mistakes in observation and judgment. Rear-end collisions and head-on collision accidents of electric locomotives in underground alleys occur frequently. Due to the ...
