APPARATUS FOR CONTROLLING ELECTRONIC UNIT OF RAILWAY CROSSING

PURPOSE: An apparatus for controlling an electronic unit of a railway crossing is provided to prevent an accident due to errors of railway crossing equipment by checking and predicting each state of the railway crossing equipment. CONSTITUTION: An active unit(100) is formed with a main control portion(110) for monitoring a railway crossing and controlling a control operation, a multiple transmission portion(120) for performing communication with a plurality of railway crossings, a relay(130) and a surge protector(131) for removing external noise, and an interface portion(140) for inputting and outputting data. An alarm control portion and an automatic alarm backup portion(150) generate an alarm sound and operate a circuit breaker. An automatic control box locking portion(166) and a control box monitoring portion locks a control box, automatically. An orbit voltage measuring portion(170) measures a voltage and a frequency between both ends of an orbit circuit. An error detection process portion(180) detects and processes an error generated from the railway crossing. The alarm control portion and a voice processing portion(190) process the alarm sound and a voice message. An automatic switch portion(200) performs a dualization operation.
