Abstract
The invention provides a sand table model car automatic tracking technique for rail teaching. The sand table model car automatic tracking technique comprises radio frequency tag location, wireless communication and an anti-collision radar. The sand table model car automatic tracking technique provided by the invention can solve the problem in automatically tracking the sand table model car for rail teaching.
Description
Technical field
The invention belongs to track traffic information engineering and control field, particularly a kind of track teaching sand table model car tracer technique.
Background technology
The train tracer technique is the train Advanced Control technology of control automatically, and especially the automatic tracer technique of track traffic teaching sand table model car does not also have a kind of technology to follow the trail of automatically by reasonable completion model car at present.In the teaching of each relevant speciality of railway universities and colleges, often to simulate the on-the-spot practice process of railway, need the combining with teaching sand table to carry out the practical operation training, the car that need use a model in the operation training is controlled automatically and is followed the trail of automatically.
Existing train is followed the trail of main the employing automatically; The ground control centre through car ground, the position and the speed of service of all trains on the car communication grasp track circuit; Mobile mandate (driving permission) through calculating each train sends to corresponding train; Train is accepted the mobile mandate that send the ground control centre, based on the mobile authorization control train of accepting in mobile safe operation within the scope of authority.Problem is position and the travelling speed that train on the track circuit is grasped in the ground control centre comprehensively, need a large amount of car ground, car communication, be a kind of technology of concentration of risk, control center has the initiative in hands, all passive execution of train on the circuit.
Summary of the invention
The technical matters that the present invention solved is to provide a kind of simple track teaching sand table model car automatic tracer technique.
Realize that the object of the invention technical solution is: the automatic tracer technique of a kind of track teaching sand table model car.Comprise RF tag location, radio communication, collision avoidance radar.
The automatic tracer technique of this said track teaching sand table model car adopts the RF tag location, reads the RF tag numbering of each root sleeper in the model car walking process, through the recognition radio frequency label numbering, confirms the position that model car is current.
Principle of the present invention is: model car adopts the communication position that this car is current in time to notify the back car.
Back car receives the position of front truck and the distance that the position of self calculates two cars, and according to two following distance controlling models car travelling speed, distance is quickened, and distance is closely slowed down.
The present invention compared with prior art, its remarkable advantage is: 1) the present invention adopts RF tag location, front truck adopts the communication position that this car is current in time to notify the back car; 2) the back car receives the position of front truck and the distance that the position of self calculates two cars, and according to two following distance controlling models car travelling speed, distance is quickened, and distance is closely slowed down; 3) after the nearly deceleration of distance, when distance reaches the operating distance of collision avoidance radar, stop by collision avoidance radar control back car, the assurance train is followed the trail of safety.4) the present invention cancels the ground control centre, and all trains adopt the scattered risks technology according to the position and speed information calculations safe distance of front truck wireless transmission.5) because the cancellation ground control centre has avoided a large amount of ground car, train-ground communications to reduce the round transmission time-delay of information, make the rapid more real-time of control command obtain enhancing, reduced the time-delay of control command.
Below in conjunction with accompanying drawing the present invention is described in further detail.
Description of drawings
Fig. 1 ground control centre control train is followed the trail of the working condition synoptic diagram automatically.
Fig. 2 train Autonomous Control train is followed the trail of the working condition synoptic diagram automatically.
Embodiment
In conjunction with Fig. 1, existing ground control centre control train technology, train sends to the ground control centre through train-ground communication with the position and the travelling speed of this car.The ground control centre receives the Position And Velocity of all trains on the track circuit; The mobile mandate that draws each train through COMPREHENSIVE CALCULATING sends to corresponding train through ground car communication; Train receives the mobile mandate that send the ground control centre, and the control train is in mobile safe operation within the scope of authority.
In conjunction with Fig. 2; Train Autonomous Control train automatic tracking system of the present invention; Trains all on the circuit are all in time notified follow-up following train with own current position and speed through radio communication, and follow-up following train receives the position and speed information of front truck, the computationally secure distance; Distance is quickened, and distance is closely slowed down.
After the nearly deceleration of distance, when distance reaches the operating distance of collision avoidance radar, stop by collision avoidance radar control back car, the assurance train is followed the trail of safety.
