Automatic coke oven signal memorizing method

Abstract

The invention relates to an automatic coke oven signal memorizing method. The method is characterized by comprising steps that: 1), whether control equipment does motions is firstly determined; 2), whether the control equipment is at a proper position is secondly determined; 3), virtual signal compensation is carried out when an oil cylinder is determined to do motions at an improper position, and record is carried out in a control system; 4), simulation compensation is directly carried out through the signal at every time when operation is carried out at the furnace number recorded in the third step; and 5), alarming and artificial intervention are carried out when deformation quantity surpasses a set control stroke. The method can memorize a large deformation quantity signal of a coke oven door, simulation compensation on the deformation quantity signal is carried out, when the deformation quantity surpasses a certain deformation quantity, alarming prompt is carried out.

Description

technical field [0001] The invention relates to electric control technology, is a method designed for unstable signals in the coke oven automatic control process, and belongs to the field of electric technology. Background technique [0002] In the coke oven process, the most common problem is that due to the deformation of the coke oven body structure or the influence of other factors, the detection signals of many of the equipment controlled by the four major vehicles cannot be in place during the actual operation process, such as coke pushing. The signal of pressing the lower latch when the car takes the door is often affected by the deformation of the furnace door and the tar sticking on the latch. Although the oil cylinder presses the lower latch, the oil cylinder is not fully extended to the actual control length, and it cannot be fully in place for signal detection. For the sequence control of the entire vehicle, because the interlock of the signal is not satisfied,...

Problems solved by technology

[0002] In the coke oven process, the most common problem is that due to the deformation of the coke oven body structure or the influence of other factors, the four major vehicles in the actual operation During the process, the detection signals of many of the controlled equipment could not be in place. For example, the signal of pressing the lower latch when the coke pusher took the door was often affected by the deformation of the furnace door and the tar adhesion on the latch. Although the oil cylinder pressed the lower latch, the cylinder did not completely Extending to the actual control length, it cannot be completely in place for signal detection. For the sequence control of the whole vehicle, because the interlocking of the signal is not satisfied, the entire automatic process stops, and only manual intervention can be performed. For a coke oven, the deformation of the furnace door with hundreds of holes is different. In the actual production process, there are many cases where the signal is not in place, but it is not possible to change the system data to meet the large deformation of some parts. furnace door, it is very dangerous for the furnace door with small deformation, so the unstable signal of coke oven control equipment is a key factor that leads to the inability of domestic coke ovens to be fully automatic
