Controller of electric derailer for radio-frequency IC card reader based on field bus

Abstract

A motor driven controller of derailer based on on-site bus radio frequency IC card reader is prepared as using programmable logic controller stored with control program as core to exchange data with radio frequency IC card reader through RS232 communication interface and to make communication with central control computer through PROFIBUS DP bus as well as to connect to motor driven derailer on-position signal detection unit and marker light break -line alarm unit through digital input interface for detecting on-position signal and marker light state of derailer and for controlling derailer to be top cast or to be bottom cast.

Description

Technical field [0001] The invention relates to an electric derailer controller of a radio frequency IC card reader based on a field bus, which is used to control the up and down of the electric derailer at the front and the rear of a railway train inspection operation line to protect the train inspection operation Personal safety of personnel. Background technique [0002] The derailment device is commonly known as iron shoes. It is a device that is placed on the rail when in use and can lift the train off the rail. Train inspectors often need to drill under the wheels when inspecting cars. If a train accidentally breaks in at this time, it will cause personal injury. Therefore, it is necessary to install a derailer at each end of the railway operation line. Its function is to cause accidental entry. When driving, the train can be turned down, thereby protecting the personal safety of the inspectors. [0003] At present, active derailment devices or electric derailment devices b...

Problems solved by technology

[0004] Since the movable derailer often needs to be moved, its weight is lighter than that of the electric derailer, and its reliability factor is not as good as that of the electric derailer. Moreover, it often happens that the inspectors are lazy and do not use the movable derailer, and they tend to forget to remove the derailer after the work is over.

[0005] The electric derailer based on the button operation cannot effectively guarantee the limitation of the operator's authority. It is difficult to realize the special operation and management of the electric derailer due to the scattered equipment of the railway operation line, outdoor operations, and many idlers.

[0006] Both derailers have certain safety hazards

Once an accident occurs, the consequences will be disastrous
