Embodiment Construction

[0037] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0038] like figure 1 As shown, the hydraulic switch control and display system according to the present invention includes a feedback unit 10 , a processing unit 20 , an action control unit 30 , a display unit 40 and a monitoring unit 50 . The hydraulic switch control and display system involved in the present invention is aimed at a five-wire AC electric switch machine, such as a ZY7 series electrohydraulic switch machine.

[0039]The feedback unit 10 includes a command processing module 101, a state acquisition module 102 and a state feedback module 103, wherein the command processing module 101 receives the control command sent by the interlocking machine, and performs voltage conversion processing on it, and converts the 24V / 5HZ signal sent by the interlocking machine The control command is converted into a 5V / 5HZ pulse, and the process...

Abstract

The invention discloses a hydraulic turnout junction control and representation system which comprises a feedback unit, a processing unit, an action control unit and a representation unit. The representation unit acquires representation states of turnout junctions and feeding the representation states to the feedback unit; the feedback unit acquires the turnout representation states fed by the representation unit and level states of protection relays and transmits the turnout representation states, the level states and control commands acquired from interlocking machines to the processing unit; the processing unit is used for receiving the control commands, the representation states and the level states which are transmitted by the feedback unit and transmits driving commands to the action control unit according to the control commands and state information; the action control unit is used for receiving the driving commands transmitted by the processing unit and completes corresponding actions according to the driving commands. The hydraulic turnout junction control and representation system has the advantages of small size, compact equipment, rich information and representation forms, easiness in fault control and analysis and the like.

Description

technical field [0001] The invention relates to the control field of railway turnouts, in particular to a control and display system of hydraulic turnouts. Background technique [0002] ZY (ZYJ) 7 series electro-hydraulic switch machine and its supporting installation device and external locking device are new switch switching systems developed to meet the needs of speed-up lines in my country. It can convert and lock domestic existing internal and external locking turnouts of various specifications and models, and can correctly reflect the positions and states of switch rails and movable center rail frogs. The ZYJ7 electro-hydraulic switch machine passed the technical appraisal of the Ministry of Railways in 1997, and obtained the national key new product certificate in December of the same year. [0003] At present, the electro-hydraulic switch machine is controlled by means of relays, and 11 relays are needed to control a group of electro-hydraulic switch machines. The d...
