Description
Technical field
The present invention relates to measuring vehicle speed range finding field, the particularly automobile-used stadimeter that tests the speed of one.
Background technology
The existing stadimeter that tests the speed mainly calculates the speed of object moving and two spaces of points or air line distance by the conversion of a pin video camera and movement, but can not good measurement space any two points distance, and measuring accuracy is not high.Driver can accurately not measure the precision of automobile code table and mileometer, uses simultaneously and be difficult to accurately grasp current speed yet in walking or bicycle.
For the problems referred to above, provide a kind of novel stadimeter that tests the speed, improve the accuracy of measuring, guarantee that automobile, pedestrian and bicycle can judge oneself speed accurately.
Summary of the invention
Technical matters to be solved by this invention is, provides a kind of automobile-used stadimeter that tests the speed, improves the accuracy of measuring, guarantee that automobile, pedestrian and bicycle can judge oneself speed accurately.
For achieving the above object, technical scheme of the present invention is, a kind of automobile-used stadimeter that tests the speed, it is characterized in that: the described stadimeter that tests the speed is the speed range information of chip difference pick-up transducers and pin camera, receive the velocity and distance that the next operation information of button transmission calculates objects ahead simultaneously.
The described stadimeter that tests the speed is provided with photosensitizing type accumulator for chip provides electric energy.
Described chip, button, photosensitizing type accumulator, sensor and pin camera are encapsulated in enclosure interior.
Described button is given prominence to and housing, handled easily.
Described surface of shell is provided with micro-heavy plane for the protection of pin camera.
On the goat's horn that the described stadimeter that tests the speed is placed on the broader place of automotive visibility or bicycle or pedestrian can hang over front or the back of the body rearward, the object of motion is placed on a relatively motionless position; After placement, pin camera 2 is aimed at one, roadside point as object of reference; Then press the button 5 and enter duty.
A kind of automobile-used stadimeter that tests the speed, owing to adopting above-mentioned structure, the present invention can check the precision of automobile code table and mileometer, pedestrian and bicycle accurately can judge oneself speed, accurate measurement space or interplanar any two points distance accurately.

Embodiment
As Figure 1-4, the present invention is the speed range information of chip 4 difference pick-up transducers 3 and pin camera 2, and the operation information simultaneously receiving button transmission 5 calculates the velocity and distance of objects ahead.
The stadimeter that tests the speed is provided with photosensitizing type accumulator 6 for chip 4 provides electric energy.It is inner that chip 4, button 5, photosensitizing type accumulator 6, sensor 3 and pin camera 2 are encapsulated in housing 1.Button 5 is given prominence to and housing 1, handled easily.Housing 1 surface is provided with micro-heavy plane for the protection of pin camera 2.
Concrete, photosensitive accumulator 6 (or similar stabilized power source) provides the energy for chip computing, conversion, record, shooting etc.; Sensor 3: touch sensor, a similar switch, perceived distance and time, by the signal processing unit in chip, can accurately calculate space rate and curve speed;
Containing amplification/shaping circuit in chip 4, the processing unit, resistance, electric capacity etc. of voltage regulator circuit, process measuring-signal, chip 4, after reading tactility apparatus perception speed out and speed, makes corresponding conversion:
A, when opening ON, distance knotmeter start to record object of reference, air line distance and space rate can be measured according to moving object;
B, when pressing START, distance knotmeter just can experiment curv distance, and curve speed;
If c presses ON, when pressing START, distance knotmeter just can measure air line distance and space rate and curve distance simultaneously simultaneously, and curve speed;
D, OFF key, only plays closing function to ON part; Display is not affected to the curve distance of START key and curve speed;
E, OVER key, only closes effect to START; Display is not affected to the air line distance of ON key and space rate;
If f, for pressing ON and START simultaneously, after recording a segment distance, presses OFF and OVER part simultaneously, display screen display Distance geometry speed at that time;
G, key have the function of zero concurrently, there will be order of whether making zero continuously, again will make zero by ON by twice ON display screen;
At automotive visibility, the present invention is placed at broader place; Or on the goat's horn of bicycle; Pedestrian can hang over front or the back of the body rearward, the object of motion is placed on a relatively motionless position (allow in a word distance, speed measuring instrumentation on pinhole cameras range of observation large as much as possible); After placement, pin camera 2 is aimed at one, roadside point as object of reference; Then the ON button on switch 5 is pressed; (pressing START key can experiment curv distance, and curve speed to press START button on switch 5 again; If do not press this part only can retain measurement air line distance and space rate); Now distance, speed measuring instrumentation just start to enter duty, now can start from scratch record data and measuring speed, also can record data from a class value of setting; The OFF key pressing the button 5 is terminated if measure.
The anti-electromagnetic interference (EMI) material of housing 1, use does not worry that it has an interference and reduces precision, photosensitizing type accumulator can brake energy accumulation when there being light, similar accumulator as: rechargeable battery is (when lower than trouble free service energy, system can remind user of service to charge in time), solar energy storage device etc., this time distance of invention, the advantage of speed measuring instrumentation: safety, environmental protection, low-carbon (LC), accurately, the ability of detecting distance and speed strong (curve and straight line can measure), to be easy to carry.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that technical solution of the present invention is carried out, or directly apply to other occasion, all within protection scope of the present invention without improving.
