Description
Technical field
The present invention relates to the correlative technology field of speed gage calibrating apparatus, particularly a kind of non-contact speed gage calibrating apparatus.
Background technology
Non-contact speed gage is an automobile performance test with one of most important, the most frequently used checkout equipment, it is a core component by microcomputer, adopt photoelectric sensor and correlation filtering technology, be equipped with corresponding I/O interface, irregular specific reflection speckle image is transformed to frequency signal on the collection road surface, become digital quantity through the A/D conversion and send into computing machine, calculate vehicle velocity V, operating range S, acceleration time t and oil consumption etc. by respective formula, and show.The measuring error of metrograph itself reaches ± and 1%.
The way of confirming the accuracy of measurement of contactless metrograph own has only " Road Detection method " and " rotary drum detection method " two kinds at present." Road Detection method " is to select a 1km, and straight road surface is provided with the trigger point of set a distance, condition harshness betwixt.Because the driver is difficult to guarantee " speed stabilizing " when working control, the factor that therefore influences measurement result accuracy is too many." rotary drum detection method " is to make the rotary drum of a diameter greater than 1m, and rotary drum produces different linear velocities to detect the accuracy of metrograph to rotate under the different regulation rotating speed situations.The investment of this method is very big, structure is huge, can not carry out scene detects, and the plane of reflection of the 80cm*100cm of tested metrograph photometer head irradiation requirement can't guarantee, just brings unreliability to measurement result.
Summary of the invention
The objective of the invention is for a kind of non-contact speed gage calibrating apparatus is provided, having solved traditional Road Detection method and rotary drum detection method, to carry out cost height, structure that velograph calibration exists huge, and the problem of poor reliability.
For achieving the above object, the present invention has adopted following technical scheme:
The invention discloses a kind of non-contact speed gage calibrating apparatus, comprise power supply, motor, microcomputer, it is characterized in that: device is provided with a synchronous cog belt and is placed on one group of synchromesh gear, the outer surface of cog belt is a simulated roadway, synchromesh gear is by motor-driven, and motor is connected with the microcomputer electric signal.
Described synchromesh gear is provided with photoelectric encoder, and photoelectric encoder is connected with the input end of microcomputer.
Described microcomputer is connected with motor by frequency converter.
Be connected by serial ports between described frequency converter and microcomputer.
Described microcomputer is connected to LCD and button.
Preferably, described motor is a synchronous motor.
Because adopted above scheme, the beneficial effect that the present invention is possessed is: guarantee the accuracy to tested metrograph motion transmission of quantity value, design science is reasonable, the accuracy of detection height, and also simple to operate, easy to carry, reliable, with low cost.
