A method for judging the precise alignment of coke quenching cars

Abstract

The invention relates to a method for judging the precise alignment of a coke-quenching car, comprising the following steps: 1) assigning the real-time measurement value S of the encoder to S at the moment when the code plate reading head is aligned with the code plate 0 , S 0 That is, the measured value of the encoder representing the position of the code plate; 2) Calculate the real-time position difference between the current position of the quenching car and the position of the currently displayed code plate, that is, the real-time code plate deviation S1; S 1 =S-S 0 ; 3) Deviation S to the real-time code plate 1 Limit the range, ‑100mm≤S 1 ≤100mm; when S 1 When the value of is within the limited range, it is considered that the furnace number of the reading head shown is accurate, and the focus can be pushed; when S 1 When the value of is outside the limited range, it is considered that the furnace number of the reading head shown is distorted and the focus cannot be pushed. The advantages are: the accuracy and reliability of the coke quenching car furnace number are greatly improved, the utilization rate of the four-car interlocking system is improved, and the occurrence of red coke landing accidents and secondary safety accidents is avoided.

Description

technical field [0001] The invention relates to the field of coking automation control, in particular to a method for judging the precise alignment of a coke quenching car. Background technique [0002] In coking production, the coke pushing car, coke blocking car, and coke quenching car must be aligned with the same furnace number to complete the coke pushing operation. Therefore, all coking enterprises have basically installed a four-car interlock protection system. However, in the actual production process, the location of the coke quenching station is often inaccurate due to the wrong address of the coke quenching vehicle, resulting in red coke landing accidents, threatening the personal safety of operators. [0003] See figure 1 , the displayed furnace number of the coke quenching car is calculated from the code plate reading head furnace number and the encoder furnace number, and its accuracy depends on the accuracy of the reading head reading of the code plate and th...

AI Technical Summary

Problems solved by technology

The furnace number distortion of the encoder comes from the cumulative error caused by wheel slippage, which will cause the measured value to be greater than the actual value, resulting in furnace number distortion

The distorted furnace number is as follows Figure 5-Figure 7 As shown, such a furnace number cannot meet the requirements for precise alignment of the quenching car, and there are potential safety hazards
