Comprehensive safety protection system for automatic driving of coke oven electric locomotive

Abstract

The invention discloses a comprehensive safety protection system for the automatic driving of a coke oven electric locomotive, which relates to the technical field of automatic control of coke oven production vehicles in the coking industry. The comprehensive safety protection system for the automatic driving of coke oven electric locomotive comprises a first vehicle-mounted PLC controller, wherein the first vehicle-mounted PLC controller is separately connected with a automatic power failure brake protection subsystem, a brake detection fault subsystem, a laser scanning anti-collision safetyprotection subsystem, a forced downshift detection protection subsystem, a coke tank rotation detection fault subsystem, a traveling variable-frequency detection fault subsystem, a system communication detection fault subsystem, an address detection protection subsystem and a manual unconditional switching and emergency stop protection subsystem. The comprehensive safety protection system for theautomatic driving of the coke oven electric locomotive can solve the problems of active derailment or collision accidents caused by out-of-control running of the electric locomotive in the prior art,red coke falling or coke tank lifting and decoupling accidents caused by abnormal rotating control of the coke tank of the electric locomotive, and passive collision safety accidents caused by intrusion of people and objects during the automatic running of the electric locomotive without effective protection.

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 comprehensive safety protection system for automatic driving of coke oven 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, ...
