Abstract
A switch monitor system features that a switch information acquisition unit is arranged for each switch group, and each acquisition unit is connected with a switch sub-unit via 2-line electric powder line which has been scrambled and then to switch monitor system connected to signal microcomputer monitor network system via CAN bus.
Description
The present invention relates to the railway signal technology field, is to each disperses the hydraulic performance of actual position, switch closure state and the hydraulic point machine of track switch to monitor and one overlaps monitoring system with what monitoring information combined with microcomputerized signal monitoring network in the railway station specifically.
The trend of railway interests's switch location decision train in case switch location is made mistakes, can cause the generation of great train operation accident immediately.Track switch is pressed interlock connection control by railway signals equipment, at present the signalling set that extensively adopts of the railway system is 6502 electric horn interlocking apparatus, and this equipment is uncontrollable and find to operate against regulations when maintenance, construction the outdoor track switch actual position that causes and the inconsistent problem of expression relay of indoor expression switch location.The applicant is devoted to research, the manufacturing of signalling set microcomputer detecting system for many years, and two degree participate in the tackling key problem of the Ministry of Railways to this project.The applicant is the application for a patent for invention to Patent Office's proposition " switch position checking method " on October 17th, 1997, application number 971066612.The applicant has proposed the application for a patent for invention of " microcomputerized signal monitoring network system " again on March 16th, 2000, application number 00114927X, this system has set up independently track switch extension set to the monitoring of turnout work state, finish monitoring to 6502 electric horn interlocking apparatus track switch actuating relays and track switch action current, but above achievement comprises that " the TJWX-2K signal microcomputer monitoring system " of Ministry of Railways's tackling key problem is fixed to track switch, how the antiposition switching process determines to check whether post falls into the inspection piece and breach is answered＜1.5 ± 0.5mm, whether the closely connected answering＜4mm of track switch stock rail and tongue can not solve, normally can not monitor the hydraulic point machine conversion power of control track switch conversion.The Switch monitor equipment that applicant in 1999 is developed into the three wire system transmission has again been installed on probation, but general station there is no the standby heart yearn of enough cables, and usage condition is limited.
The objective of the invention is on above-mentioned achievement basis, improve a kind of system to the comprehensive monitoring of track switch, promptly track switch is being decided, the antiposition switching process, check that post falls into inspection piece breach and answers＜1.5 ± 0.5mm, whether the hydraulic point machine hydraulic performance of closely connected answering＜4mm of track switch stock rail and tongue and the conversion of manipulation track switch meets the requirements and monitors in real time, and above information is connected with microcomputerized signal monitoring network so that centralized displaying, control, simultaneously tens groups in the station even component up to a hundred are casually arranged with the track switch of putting, utilize the defeated passage of original electric power two-wire system supply line double as Switch monitor information and form a kind of switch monitor system of network.
For finishing the technical scheme that above-mentioned purpose adopts, every group of other harvester of establishing of track switch gathered track switch information, each harvester links to each other with the Switch monitor extension set by original two-wire system 220V (or 110V) electric wireline of handling through electric network noise and forms network, is connected to microcomputerized signal monitoring network system through the CAN bus again.Harvester is finished switching value, analog acquisition respectively by track switch location, antiposition, closely connected sensor and hydraulic point machine sensor.Harvester and Switch monitor extension set are all established multiple lightning protection and are suppressed work frequency circuit, coupling module, spread spectrum module and CPU.Harvester of the present invention is by pizo-resistance R

Simultaneously, the present invention connects by original electric wireline two-wire system, and the track switch of disperseing to install is formed network.Harvester works in real-time monitoring state, monitor that by two-wire system electric wireline and track switch extension set carries out data exchange, the Switch monitor extension set also links to each other perfect, as to have enlarged Ministry of Railways's brainstorm project " TJWX-2K signalling set microcomputer detecting system " function by CAN bus and upper computer----signalling set microcomputer detecting system.
The embodiment of the invention is described in detail in conjunction with the accompanying drawings.
