Description
Technical field
The utility model relates to the correlative technology field of speed gage calibrating apparatus, the simulation moving pavement device that particularly a kind of speed gage calibrating apparatus is used.
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.
The utility model content
The purpose of this utility model is for the simulation moving pavement device that provides a kind of speed gage calibrating apparatus to use, and 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 utility model has adopted following technical scheme:
The utility model discloses the simulation moving pavement device that a kind of speed gage calibrating apparatus is used, comprise power supply, motor, 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, the inner surface of cog belt is provided with tooth, match with synchromesh gear, synchromesh gear is by motor-driven.
Described motor is connected with a microcomputer electric signal.
Described microcomputer is connected with motor by frequency converter.
Preferably, described motor is a synchronous motor.
Owing to adopted above scheme, the beneficial effect that the utility model is possessed is: a kind of simulation moving pavement is provided, satisfied the photometer head irradiation requirement of tested metrograph, it is the plane of reflection of 80cm*100cm, thereby guaranteed accuracy, the accuracy of detection height to tested metrograph motion transmission of quantity value.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
The simulation moving pavement device that a kind of speed gage calibrating apparatus is as shown in Figure 1 used, comprise power supply, synchronous motor 1, it is characterized in that: device is provided with a synchronous cog belt 2 and is placed on one group of synchromesh gear 3, the outer surface of cog belt 2 is a simulated roadway, the inner surface of cog belt 2 is provided with tooth, match with synchromesh gear 3, synchromesh gear 3 is driven by synchronous motor 1.Microcomputer 4 is connected with synchronous motor 1 by frequency converter 5, and 4 of frequency converter 5 and microcomputers are connected by serial ports 6.During use metrograph 7 is fixed in the top of synchronous cog belt 2, can carries out speed calibrating and cumulative distance calibrating easily.
