Description
Technical field
The present invention relates to a kind of in the position of ground detection rail vehicle and the method for translational speed.
Background technology
Chinese invention patent prospectus CN1769845A (open day on May 10th, 2006) discloses a kind of detection method along track moving object position and speed.This method relatively moves based on the baffle-type printing opacity principle judgment object that is in the light, its ground positioning speed-measuring system is by the teeth groove plate, a plurality of partition detector and a Upper Processor are formed, the teeth groove plate is the passive equipment that is in the light, when it and partition detector relatively move, partition detector is calculated the rate of travel of vehicle according to the change frequency of detected positioning states, the sequential decision that shifts in circular list according to positioning states is along the moving direction of track mobile object, and Upper Processor merges position and the speed that calculates mobile object behind the detected signal of all partition detector.There is following problem in the detection method of this track moving object position and speed in practicality:
When 1) circuit is longer, the One's name is legion of partition detector, and Upper Processor will be connected with all partition detector, causes the interface quantity of Upper Processor big, the handling procedure complexity makes design, production, debugging and safeguards all very difficult;
2) only realized the relative positioning function;
3) fault of any partition detector in all fronts all will cause the paralysis of total system;
4) only be applicable to the situation that a car is only arranged completely.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of rail vehicle ground positioning speed-measuring system, it can be carried out preferably than long transmission line rail vehicle positioning-speed-measuring function, realize relative positioning and absolute fix simultaneously, and by equipment redundancy and method for diagnosing faults, make that total system still can operate as normal under the situation that the part partition detector is damaged.
For solving the problems of the technologies described above, rail vehicle ground positioning speed-measuring system of the present invention, include the teeth groove plate that is installed on the rail vehicle, a plurality of partition detector in orbit are installed, a hard-wired Upper Processor, and between partition detector and Upper Processor, have an intermediate processor at least, and the partition detector of some is connected with an intermediate processor, and this intermediate processor is connected with Upper Processor; The installing space of partition detector is made as, and has at least two partition detector can detect the teeth groove plate simultaneously at an arbitrary position; The information of partition detector is transferred to the intermediate processor of last layer earlier, after handling, intermediate processor gives Upper Processor with effective subregion check point information transmission, after getting rid of coincidence and failure message, Upper Processor obtains the number of actual significant positioning-speed-measuring point, it is the number of vehicle on the circuit, and obtain the position and the speed of each car, the coding of output fault partition detector according to the positioning-speed-measuring waveform.
Rail vehicle ground positioning-speed-measuring method of the present invention is by introducing intermediate processor in partition detector and Upper Processor, partition detector is carried out grouping management, on the basis that does not increase the Upper Processor complexity, realize modular design, production, debugging and maintenance, realize positioning-speed-measuring preferably than all rail vehicles on the long transmission line.Under the last layer processor management in the process of one deck processor, except that the pulse information that obtains location usefulness, record provides the partition detector coding of this information simultaneously: when the partition detector that initial alignment information is provided switches, Upper Processor can obtain this information, the position of the vehicle when corresponding partition detector switches is fixed, and so just can obtain the absolute position of vehicle; At non-switching point, the vehicle absolute position adds that by the position of absolute reference point mobile relative quantity obtains, and has taken this to realize the absolute fix of rail vehicle.In addition, at an arbitrary position, have at least 2 partition detector can detect the setting of this partition detector installing space of teeth groove plate simultaneously, make when having 1 to break down in 2 continuous arbitrarily partition detector, can draw the positioning-speed-measuring signal by normal partition detector, can not provide the partition detector of positioning-speed-measuring signal then to be considered to break down, having guaranteed under the situation that equipment component damages still can operate as normal, detects the equipment that breaks down simultaneously.
Description of drawings
The present invention is further detailed explanation below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the information transmission system synoptic diagram of a specific embodiment of rail vehicle ground positioning-speed-measuring method of the present invention;
Fig. 2 is the processing synoptic diagram of intermediate processor of the present invention;
