An optimal alignment method for electric cars at the traction point

Abstract

The invention discloses an optimal alignment method of a tram at a traction place. It adopts the method of changing the distance between two code plates that are too close together, changing the position of an encoder, and stopping the tram after it is out of shape to the target code plate and then checking again. The way is changed to the way of checking in advance during running to ensure that the electric car can achieve accurate alignment in the traction and the nearby code plate position, and ensure the final alignment accuracy, especially in the traction position where the alignment accuracy is higher. Occasions can also meet the alignment requirements, laying the foundation for the automatic control of trams.

Description

technical field [0001] The invention relates to an electric car automatic control technology, in particular to an optimal alignment method of an electric car at a traction place. Background technique [0002] The trolley is an important part of coke oven production, and its duty is to send the coke pots connected with red coke to the CDQ equipment. Such as figure 1 As shown, the tram is composed of a towing car and two coke tank cars, running on the tram track, the tram picks up the empty coke tank from the traction, and then sends the empty coke tank to the bottom of the coke guide car, after the red coke is connected Then send the red coke tank into traction. The tram uses a rotary encoder plus a code plate alignment method to ensure the accuracy of travel. Among them, the code plates are arranged according to the spacing of each coke oven hole of 1.5 meters, and correspond to the coke oven holes one by one. When the code plates are well aligned, it means that the preci...

[0003] The traction of the coke oven in Phase 4 of an ironworks is in the same horizontal area as the coke oven, so the code number of the traction is located in the middle of the code number of the coke oven hole, specifically as follows figure 2 As shown, for example, because the No. 76 coke oven number plate on the right side is too close to the No. 128 traction number plate, only 245mm and less than the length of the number plate by 350mm, the number plate reading head may read the signal of the number plate. The signal of the traction code plate and the coke oven code plate on the right is read at the same time, which will trigger the wrong signal of the reading head and make it impossible to get the correct position, and it will also prevent the tram from running accurately.

Because the traction must ensure accurate alignment, otherwise it will not be possible to pick up the coke tank

In this regard, the current solution is to remove the left and right furnace number plates near the traction code plate to ensure that it can travel to the traction position correctly, and rely on manual confirmation of the position at the two furnace number plates next to it, which is very troublesome and greatly hinders the automated control of the tram
