Method for detecting and controlling abnormal speed of coke oven locomotive

Abstract

The invention relates to a method for detecting and controlling the abnormal speed of a coke oven locomotive. The method includes the following steps that 1, a displacement identification device is arranged in a vehicle deceleration area, the displacement identification device adopts an encoding mode of 8421 codes for encoding, signals can be read by a vehicle-mounted control system, and the vehicle-mounted control system calculates the current location of the locomotive through the read information and conducts timing; 2, collection of standard time through different displacement segments iscompleted, the vehicle-mounted control system collects the time of the coke oven locomotive passing by each segment in the deceleration process to obtain standard passing time, the actual time of thelocomotive passing by each segment is collected and recorded in real time during production and compared with the standard passing time of the segment, if the time difference is large, that is to saythat the speed is abnormal, and an alarm signal is output; 3, automatic protection of the abnormal speed is achieved. After the vehicle-mounted control system automatically confirms that the speed isabnormal, deceleration or emergency stop protection is automatically performed according to a set protection method to avoid accidents caused by the abnormal speed of the locomotive.

Description

technical field [0001] The invention relates to a method for detecting and controlling the abnormal speed of a coke oven locomotive, belonging to the technical field of coke oven control. Background technique [0002] The coke pushing car, coke holding car, coal feeding car and electric locomotive system (referred to as the four major cars) of the coke oven are important equipment in coke oven production, and their operating conditions directly determine the quality and output of coke oven production. The running system of the four major coke oven vehicles is an important link in the production and operation of each vehicle. Heavy-duty, high-speed locomotives run at high speed on the track. If the speed control is abnormal, it will cause serious consequences such as crashes. Taking the electric locomotive as an example, it includes a power locomotive and two transport vehicles (see figure 1 Side view and top view), the power locomotive drags the 1# carrier car and the 2# ca...

AI Technical Summary

Problems solved by technology

Since the track is installed in the open air, the wheel may change from a rolling state to a sliding state on the track when the load changes drastically, but the original speed monitoring system fails to detect, and the speed setting device gives the speed value according to the wrong feedback signal , leading to loss of speed control and serious accidents

Especially in the case of fully automatic alignment, due to the lack of a reliable speed detection device and speed control method, the out-of-control coke oven locomotive still runs at the original set speed, resulting in particularly serious consequences, requiring a new technical solution to solve the above problems
