Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0025] figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 with Image 6The shown coke oven electric locomotive automatic driving positioning control method is realized by using the coke oven electric locomotive automatic driving positioning control system. The system includes an address decoder 2 installed in the four-vehicle chain system. The real-time address data of the electric locomotive for positioning the optical code ruler 1 on the ground track, and transmit the real-time address data to the first vehicle-mounted PLC controller 3, and the first vehicle-mounted PLC controller 3 transmits the real-time address data and the set target address to the second vehicle-mounted PLC controller 5, and simultaneously transmitted to the ground master controller 4 of the four-vehicle interlocking system, the second vehicle-mounted PLC controller 5 co...

Abstract

The invention discloses an automatic driving positioning control method for a coke oven electric locomotive, and relates to the technical field of automatic control of coke oven production vehicles inthe coking industry. The realization method comprises the following steps: a second vehicle-mounted PLC controller obtains an address decoder on the electric locomotive through bus communication, andtransmits to the real-time address of a first vehicle-mounted PLC controller and the target address set by a ground main controller of a four-vehicle interlocking system; the distance deviation valueW is obtained after comparing; the running feedback speed of the electric locomotive is calculated according to the distance speed model and the control algorithm, and a gear signal is output to control the walking frequency converter; the electric locomotive is driven to finish the actions of walking positioning, automatic shifting and self-adaptive adjustment. The method can solve the problemsof poor positioning accuracy, long time consumption of vehicle shifting, high labor intensity, easy fatigue of personnel, incomplete linkage and large operation hidden danger in the prior art.

Description

technical field [0001] The invention relates to the technical field of automatic control of coke oven production vehicles in the coking industry, in particular to a method for automatic driving positioning control of electric locomotives. Background technique [0002] In the coking industry, the four major vehicles are the main production equipment of coke ovens, which belong to rail machinery equipment, and have the characteristics of mechanization and large-scale, but the degree of automation is generally low. Although the four major vehicles have been designed and controlled by the PLC system for many years, and are gradually equipped with the four-vehicle interlocking system, they have basic position recognition functions. But for a long time, the four major coke oven vehicles have been operated by manual positioning and manual control. Moreover, these equipment systems require huge investment and high operation and maintenance costs. At present, the number of operatin...
