Description
Technical field
The utility model relates to the foreign body limit-intruding monitoring system of high speed railway, belongs to International Classification of Patents B61K technical field.
Background technology
When the low speed railroad train is with low cruise in the past, based on artificial driving, when on the circuit obstacle being arranged, from the visual finding to the train braking, stop, time and distance is last still can guarantee safety, unexpected less.The point section of crossing over railway at the parallel next-door neighbour of highway and railway, road bridge, automobile might take place, relatively large object pours or crashes into the situation on the railway line, when the railway line for passenger traffic train moved with the speed more than the 250km/h, Mu Shi lookout can not guarantee traffic safety, and danger increases greatly.Therefore, the foreign body intrusion monitoring should be built the same period with railway line for passenger traffic and be realized, it is the indispensable safety control of railway line for passenger traffic operation.In the driving safety monitoring system of railway information system, earthquake measuring, windproof early warning and monitoring, foreign body intrusion monitoring are the safety control information that belongs to highest ranking together.Because earthquake measuring has relative independentability, so the foreign body intrusion monitoring should be implemented with network design with windproof early warning monitoring.External existing way with the direct car controlling of foreign body intrusion alarm message.In China, it is in the ascendant that railway line for passenger traffic is built, and construction unit should pay attention to the harm of foreign body intrusion, even if wouldn't car controlling, also should determine as early as possible to report to the police and drive a vehicle management method.The windproof prewarning monitoring system of railway line for passenger traffic seminar has finished the Primary Study of windproof early warning monitoring and has passed through institute-level evaluation in January, 2007, as the foreign body intrusion monitoring of driving safety monitoring system component part.To the monitoring of foreign body intrusion, mainly contain three kinds of technological means: infrared correlative detector, video identification technology and two power network monitoring both at home and abroad.Infrared and video scheme poor anti jamming capability to the monitoring of foreign body intrusion, can not be used the mode of infrared or video separately, because infrared or video no matter all be not so good as pair power network monitoring schemes accurately and reliably.So the foreign body intrusion monitoring should be based on two power network monitoring schemes,, replenish its intuitive if the scale of investment permission is aided with infrared or video scheme again.Therefore, two power network monitoring schemes are supporting technology means of foreign body intrusion monitoring, should take the lead in being verified in engineering.Though several foreign body intrusion monitoring technique schemes are comparatively clear, all do not have ripe application practice in China railways.Particularly in conjunction with conditions such as railway line for passenger traffic circuit, bridge, communication, power supply, information-based systems, still lack a whole set of Networking Design standard that relates to system design, construction and installation standard, equipment facility standard, report to the police and upload and Regularia foundations such as emergency preplan, demand urgently obtaining above-mentioned file behind the actual engineering verification.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of antijamming capability strong foreign body limit-intruding monitoring system.
The purpose of this utility model is achieved through the following technical solutions.
A kind of foreign body limit-intruding monitoring system, it comprises electrical network sensor, field control case and monitoring unit; The electrical network sensor is connected with the field control case, and the field control case to monitoring unit, also has row controlled relay and central apparatus with the monitoring unit bonded assembly by cable connection, and monitoring unit also connects dispatch terminal by network; Described monitoring unit comprises the monitoring unit main frame that is connected with power module, and this monitoring unit main frame also is connected with the input end of combination relay.
The electrical network sensor is installed on the electrical network, and the electrical network horizontal protective that is laid in is online, and horizontal protective net is erected on the support post at high speed railway two ends.
Central apparatus mainly is made of data server, application server, disk array, exchange, monitor terminal.
Dispatch terminal equipment comprises exchange, the communication server, serial server and monitor terminal.
The utility model adopts the power network monitoring scheme, and the antijamming capability of monitored control system is strong, monitors more intuitive and reliable.Through contrast, the actual tests on Beijing-Tianjin inter-city railway is used, and is respond well.
Description of drawings
Accompanying drawing is a structural representation block diagram of the present utility model.
Among the figure: 1, monitoring unit, 2, the field control case, 3, the electrical network sensor, 4, the row controlled relay, 5, central apparatus, 6, dispatch terminal.
The specific embodiment
Referring to accompanying drawing, foreign body limit-intruding monitoring system, it comprises electrical network sensor 3, field control case 2 and monitoring unit 1, electrical network sensor 3 is connected with field control case 2, field control case 2 arrives monitoring unit 1 by cable connection, also have row controlled relay 4 and central apparatus 5 with monitoring unit 1 bonded assembly, monitoring unit 1 also connects dispatch terminal 6 by network; Monitoring unit 1 comprises the monitoring unit main frame that is connected with power module, and this monitoring unit main frame also is connected with the input end of combination relay.
The field monitoring of the utility model foreign body limit-intruding monitoring system adopts the power network monitoring scheme, promptly lays the lead with specific toughness on the net at horizontal protective, constitutes electrical network according to the design-calculated cabling mode.When the cross-sectional plane that weighs down thing greater than the electrical network grid and when weighing down the weight that thing weight can bear greater than electrical network, electrical network is pounded disconnected, system alarm.
Foreign body limit-intruding monitoring system takes into full account aspect reliability, the integraty of electrical network sensor is judged the electric current detection of dynamic mode that adopts, can effectively suppress extraneous common mode interference, make that system stability is good, antijamming capability is very strong, long transmission distance.Also can in time find the internal fault of testing circuit simultaneously by detection of dynamic.The electrical network detection module can find that electric leakage between grid short circuit, bad contact, line, electrical network mix strange phenomenies such as electricity, and failure message can be sent to the maintenance terminal, reminds the maintainer in time to handle.
