Description
Technical field
The utility model relates to a kind of magnetic suspension train and tests the speed, locatees and reflect to device.
Background technology
At present, the conventional wheel rail railway is mainly determined the speed and the position of train by track circuit and vehicle-mounted photoelectric encoder, promptly transmits signal by track circuit, realize overspeed protection, automatic interlock and train in each interval with respect to the accurate position of circuit etc.Because magnetic suspension train is suspended on the track, no touch between train and the track is so conventional way can not be used for testing the speed, locating of magnetic suspension train.This is a kind of new, practical and be used for magnetic suspension train efficiently and test the speed, locate and reflect to device with regard to needing.The utility model satisfies these needs just and proposes.
Summary of the invention
The purpose of this utility model provides a kind of magnetic suspension train and tests the speed, locatees and reflect to device, and it is simple in structure, with low cost, practical.
Test the speed, locate and reflect according to magnetic suspension train of the present utility model, comprise the sensor that is installed on the car body to device; Measure processing equipment with described sensor bonded assembly; And be arranged on identification marking on the described car body running route.
Described sensor can be installed on the car body bottom, and can adopt a plurality of.Described identification marking can be to comprise the metallo-object.

Embodiment
Fig. 1 is the structural representation of an embodiment of the present utility model, and wherein 1 is car body, the 2nd, and sensor, the 3rd, sensor stand, the 4th, be used for the identity markings that sensor is discerned, the 5th, measurement mechanism.
On the magnetic suspension train circuit, (D rice) is provided with identity markings 4 at a certain distance, the sleeper that identity markings 4 is to use steel to make in the present embodiment, also can be that other metallic materials are made, or include other objects of metallo-, so long as can all be can be used as the identity markings that is used for sensor identification by the object that sensor is discerned.The sensor of installation and measuring identification marking on the magnetic suspension train car body.Sensor is to be installed on the bottom of train 1 by support 3 in Fig. 1.The output of sensor offers the measurement mechanism of installing on the train 15.When train 1 process sleeper, sensor 2 produces electric impulse signals.5 pairs of described electric impulse signals of measurement mechanism are handled calculating, draw the gait of march of train, the advanced positions and the direct of travel of train.
The groundwork that speed, advanced positions are advanced by calculated column garage is as follows:
Measure the time T (second) between adjacent two electric pulse, just can draw train speed V according to following formula (1).
V=D
*1/T (meter per second) ... (1)
Wherein, V is a train speed, and D is the spacing distance of identification marking, and T is the pulse interval time.
To 5 quenching pulses of measurement mechanism, and then the sensor 2 of adding up produces each electric pulse N, just can record the position S of train with respect to originating station according to formula 2 at originating station.
S=N
*D (rice) ... (2)
Wherein, S is the distance that train has been advanced with respect to originating station, and D is the spacing distance of identification marking, and N is an impulse singla number that sensor produced.
Fig. 2 is that of the present utility model another is the structural representation of embodiment, has adopted a plurality of sensors among this embodiment, and other device settings are identical with Fig. 1 embodiment's, used identical label.
In the present embodiment, be to improve real-time and accuracy that train speed is measured, adopts that a plurality of (2≤n) sensors 2 are vertically arranged setting along train 1, distance between the adjacent sensors is subdivided into D/n (rice), promptly adorns 1 sensor every the D/n meter ampere on the car body mounting frame for sensor.Like this can be according to formula 3 and 4 more accurate speed per hour and the positions that record train 1.
V=D/n
*1/t (meter per second) ... (3)
Wherein, t is the time difference that two adjacent sensors produce impulse singla.
S=N
1 *D+D/n
*X (rice) ... (4)
Wherein, N
1Be that first sensor produces the pulse sum, X is that X at end produces N
1The sensor of individual pulse, 0＜X＜n.
Magnetic suspension train in the present embodiment tests the speed, locatees and reflects has mirror to function to device.In order to record the travel direction of train, the travel direction of train is differentiated in two of the fronts of n sensor before utilizing by following phase detecting method.
The groundwork of measuring direct of travel is as follows.
During the train forward travel, the waveform of two sensors as shown in Figure 3, during the train backward going, the waveform of two sensors is as shown in Figure 4.During the train forward travel, the phase place of impulse singla B hysteresis impulse singla A is (1/n) among Fig. 3
*360 degree, during the train backward going, the phase place of impulse singla B hysteresis impulse singla is A (1-1/n) among Fig. 4
*360 degree.If n=4, pulse signal B hysteresis impulse singla A90 degree during the train forward travel, therefore pulse signal B hysteresis impulse singla A270 degree during the train backward going can be differentiated the travel direction of train by impulse singla B with respect to the phase place of impulse singla A.
The signal of sensor output is an on-off signal, represent to detect sleeper such as high level, low level represents not retrieve sleeper, because sleeper is mounted in the field, under this vehicle environment, can be subjected to some interference, disturb and mainly show as spike, these spikes can influence the precision that tests the speed, also can cause the saltus step of speed, so when testing the speed, will get rid of these interference as far as possible, so the task of measurement mechanism is carried out pretreatment to switch output signal exactly, comprises High frequency filter, shaping, isolate, signal process after treatment comprises that the programming of the micro controller system of CPU records the speed of train, position and travel direction.
Fig. 5 is the circuit block diagram of measurement mechanism 5 in the utility model.Pre-process circuit 51 inputs come the signal after the detection signal of self-inductor output also will be handled to offer CPU53 among Fig. 2, CPU is according to the computing program of storage in the memory device 52, signal is carried out speed, position and the travel direction data that computing draws train, export to (not shown)s such as display equipment, digital distance scope, speech ciphering equipment.
