Abstract
The utility model provides a track teaching sand table model car locating and detecting system. The locating and detecting system comprises a radio frequency tag, a vehicle-mounted tag reader, an antenna and accessory devices and a vehicle-mounted power source. The model car locating and detecting system can solve the problem of the automatic locating of a track teaching sand table model car.
Description
Technical field
The utility model belongs to track traffic information engineering and control field, particularly a kind of track teaching sand table model car position detecting system.
Background technology
The train location is the automatically prerequisite of control of train, and especially track traffic teaching sand table model car is located automatically, does not also have at present a kind of technology can reasonablely finish the 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 the combining with teaching sand table to carry out the practical operation training, the car that needs in the operation training to use a model is location and automatically control automatically.
The main employing in the automatic location of existing train, wheel detector calculates the revolution of wheel, according to the distance that the girth conversion of wheel is travelled, 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 bearing accuracy, and this error is uncertain.Solution is to need absolute fix that cumulative errors is revised every certain distance.The track circuit that has commonly used is crossed the insulation joint correction, GPS correction etc., and these correcting methods can't be realized on model car.
The utility model content
The technical matters that the utility model solves is to provide a kind of track traffic teaching sand table model car automatic position detecting system.
Realize that the utility model purpose technical solution is: a kind of track teaching sand table model car position detecting system.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.
This described model car position detecting system, adopt different radio-frequency (RF) tag of numbering to stick on the centre position of each root sleeper, the vahicles label reader reads the radio-frequency (RF) tag numbering of each root sleeper in the model car walking process, determine the model car position by the radio-frequency (RF) tag numbering, be convenient to the automatic control of model car.
Principle of the present utility model is: the utility model sends detection signal by the vahicles label reader, stick on the centre position radio-frequency (RF) tag of each root sleeper, after receiving the detection signal of vahicles label reader transmission, return to the numbering of a radio-frequency (RF) tag of vahicles label reader.
The utility model compared with prior art, its remarkable advantage is: 1) the utility model adopts REID, vahicles label reader to send detection signal; 2) the utility model has been avoided the cumulative errors of relative positioning; 3) the utility model adopts in the centre position of each root sleeper and pastes radio-frequency (RF) tag, so that model car travels and can both position at any sleeper, avoids occurring the blind area, location.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Description of drawings
Fig. 1 radio-frequency (RF) tag equipment working condition synoptic diagram.
Fig. 2 radio-frequency (RF) identification model car location synoptic diagram.
Embodiment
In conjunction with Fig. 1, radio-frequency (RF) tag equipment working condition is usually, and RFID tag reader maintains static, and when labelled product passed through reader, reader sent radiowave, activates radio-frequency (RF) tag, and the 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 opposite usually, and each labelled root sleeper maintains static, and the vahicles label reader sends read signal when model car traveling process sleeper.Label on the fixed sleeper, receive the detection signal that the vahicles label reader sends after, 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, is included in radio-frequency (RF) tag, vahicles label reader, antenna and auxiliary device, the vehicle power of the centre position stickup of each root sleeper.
2. track teaching sand table model car position detecting system according to claim 1, it is characterized in that, this described model car position detecting system, adopt different radio-frequency (RF) tag of numbering to stick on the centre position of each root sleeper, the vahicles label reader reads the radio-frequency (RF) tag numbering of each root sleeper in the model car walking process, by the recognition radio frequency label numbering, determine the model car position, be convenient to the automatic control of model car.
