Abstract
The invention provides a locating detection system of a track teaching sand table model car. The locating detection system of the track teaching sand table model car comprises radio frequency tags, a vehicle-mounted tag reader, an antenna, accessory devices and a vehicle-mounted power source. According to the locating detection system of the track teaching sand table model car, automatic locating of the track teaching sand table model car can be achieved.
Description
Technical field
The invention belongs to track traffic information engineering and control field, particularly a kind of track teaching sand table model car location technology.
Background technology
Train location is the prerequisite that train is controlled automatically, and especially track traffic teaching sand table model car is located automatically, does not also have at present a kind of technology can reasonablely complete model car location.In the teaching of each relevant speciality of railway universities and colleges, often to simulate the practice process of Railway Site, need combining with teaching sand table to carry out practical operation training, the car that needs in operation training to use a model is location and control automatically automatically.
The main employing in location automatically of existing train, wheel detector calculates the revolution of wheel, and the distance that converts and travel according to the girth of wheel, carries out indirect addressing.Namely according to the position of previous moment, and a period of time distance of travelling, calculate this position constantly.This just needs 2 conditions, the position of previous moment, the distance that a period of time travels.Relative positioning has a unavoidable problem, is exactly cumulative errors, and the error of the distance of travelling can produce cumulative errors to later positioning precision, and this error is uncertain.Solution is to need absolute fix to revise cumulative errors every certain distance.The conventional track circuit that has is crossed insulation joint correction, GPS correction etc., and these correcting methods cannot be realized on model car.
Summary of the invention
Technical matters solved by the invention is to provide a kind of track traffic teaching sand table model car automatic positioning technology.
Realizing the object of the invention technical solution is: a kind of track teaching sand table model car location technology.Radio-frequency (RF) tag, vahicles label reader, antenna and auxiliary device, vehicle power are pasted in the centre position that is included in each root sleeper.
Model car position detecting system described in this, adopt different radio-frequency (RF) tag of numbering to stick on the centre position of each root sleeper, vahicles label reader reads the radio-frequency (RF) tag numbering of each root sleeper in model car walking process, by radio-frequency (RF) tag, number and determine model car position, be convenient to the automatic control of model car.
Principle of the present invention is: the present invention sends detection signal by vahicles label reader, stick on the centre position radio-frequency (RF) tag of each root sleeper, receive after the detection signal of vahicles label reader transmission, return to the numbering of a radio-frequency (RF) tag of vahicles label reader.
Compared with prior art, its remarkable advantage is in the present invention: 1) the present invention adopts REID, vahicles label reader to send detection signal; 2) the present invention has avoided the cumulative errors of relative positioning; 3) the present invention adopts in the centre position of each root sleeper and pastes radio-frequency (RF) tag, makes model car travel and can position on any sleeper, avoids occurring blind area, location.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 radio-frequency (RF) tag equipment working condition schematic diagram.
Fig. 2 radio-frequency (RF) identification model car location schematic diagram.
Embodiment
In conjunction with Fig. 1, radio-frequency (RF) tag equipment working condition is conventionally, and RFID tag reader maintains static, and when labelled product passes through reader, reader sends radiowave, activates radio-frequency (RF) tag, and radio-frequency (RF) tag return message is to label reader.
In conjunction with Fig. 2, model car position detecting system working condition is with radio-frequency (RF) tag equipment working condition is contrary conventionally, and each labelled root sleeper maintains static, and vahicles label reader sends read signal when model car traveling process sleeper.On fixed sleeper, label, receive after the detection signal of vahicles label reader transmission, return to the numbering of a radio-frequency (RF) tag of vahicles label reader.
Claims (2)
1. a track teaching sand table model car position detecting system, is characterized in that, radio-frequency (RF) tag, vahicles label reader, antenna and auxiliary device, vehicle power are pasted in the centre position that is included in each root sleeper.
2. track teaching sand table model car position detecting system according to claim 1, it is characterized in that, model car position detecting system described in this, adopt different radio-frequency (RF) tag of numbering to stick on the centre position of each root sleeper, vahicles label reader reads the radio-frequency (RF) tag numbering of each root sleeper in model car walking process, by recognition radio frequency label, number, determine model car position, be convenient to the automatic control of model car.
