Abstract

The utility model provides a road gradient angle measurement device which comprises an upper cover, a base, an angle limiting block, a laser emitter, a receiver, a liquid crystal screen and a microcomputer. The road gradient angle measurement device is characterized in that the device is horizontally fixed in a vehicle through the base; when the vehicle runs on a road with a lateral gradient and a longitudinal gradient; under the action of gravity, the laser emitter rotates in a spherical hole of the upper cover and perpendicularly irradiates a laser receiver rectangular array arranged on the base; laser receivers generate voltage, so that an irradiation coordinate position can be judged; and the microcomputer calculates a longitudinal gradient and a transverse gradient of the road according to coordinate values and displays the gradients on the liquid crystal screen. The road gradient angle measurement device is simple in structure, easy to manufacture and high in measurement precision and can help a driver to judge the gradient of the road, so that the driver can easily determine a driving gear position, the openness of an accelerator or the braking strength; and therefore, vehicle driving is facilitated and the driving safety is guaranteed.

Description

The road grade angle measuring device

Technical field

The utility model relates to a kind of road grade angle measuring device, is particularly useful for vehicle-mounted measurement.

Background technology

In the past, known road grade angle measuring device was the pedal line mensuration, the angle of gradient static measurement when this method is applicable to house and road construction, and the problem that this method exists is that measuring speed is slow, efficient is low, and registration automatically; When the vertical and horizontal angle of gradient of kinetic measurement running car road changed, because the restriction of installing space and the dynamic requirement that shows in the car, the vertical collimation method was also inapplicable.

Summary of the invention

The purpose of this utility model is to provide a kind of fixing onboard, and dynamically display line is sailed the road grade angle measuring device of the road vertical and horizontal gradient.

Road grade angle measuring device of the present utility model is made up of loam cake, base, angle limited block, generating laser, receiver and liquid crystal display, it is characterized in that generating laser is directly over base plate, transmitter is swung with the transmitter connecting link, thereby the receiver that shines produces the coordinate position of voltage perception irradiation, and the micro computer computing obtains the vertical and horizontal angle of gradient of road; Loam cake and angle limited block have spherical pore, and transmitter connecting link spheric end is installed between loam cake and the angle limited block, and connecting link can rotate to an angle by any direction in the angle limited block; Base longitudinally and is laterally arranged a series of laser pickoff by matrix-style, offers circular port on the base plate, and the receiver lead passes through from above-mentioned circular hole, is connected with micro computer, forms the computational analysis system; The height of the inner receiver of the aspect ratio of base plate outermost receiver is big, and sensitive surface is bigger.

Described laser pickoff, be arranged in matrix form, receive the position of the receiver of laser signal for judgement, the end formation line that connects together with each each receiver of row, with each other end that is listed as each receiver formation alignment that connects together, the capable n row of such one total n are 2n bar root line altogether, this 2n root line is connected on 2n the I/O mouth of single-chip microcomputer, just can detect n by the program scanning keyboard ²Individual position, thus determine which receiver received laser signal, determined that namely generating laser shines the coordinate position on the base plate.

Suppose that the coordinate position of laser illumination point is (x on the base plate ₁, y ₁), the laser pickoff plane is h to the height at spherical center, laser connecting link upper end, is x axle forward behind the vehicle body Y, upwards is z axle forward, pointing to the vehicle body outside is y axle forward, then road head fall angle $\mathrm{\α}=\arctan \frac{x_1}{h},$ Road cross fall angle is $\mathrm{\β}=\mathrm{arctaan}\frac{y_1}{h}.$

The beneficial effects of the utility model are: this device is installed with car can monitor the gradient of road at any time, and is presented on the liquid crystal display, helps the driver more easily to determine the gear that travels, the aperture of throttle or the intensity of braking, guarantee driving safety.

Embodiment

Below, based on description of drawings a kind of embodiment of the present utility model.

As shown in Figure 1 and Figure 2, the road grade angle measuring device comprises loam cake 1, base 2, angle limited block 3, transmitter connecting link 4, generating laser 5, receiver 6, liquid crystal display 7 and micro computer 8 compositions.

As shown in Figure 1 and Figure 2, generating laser 5 is installed on the transmitter connecting link 4, the last pommel of transmitter connecting link 4 is installed in the spherical pore of loam cake 1, and clamp with angle limited block 3, liquid crystal display 7 is installed on base 2 one sides, the array that receiver 6 is arranged in the capable n row of n is evenly arranged on the base plate of base 2, a part of in Fig. 2, only schematically having drawn receiver 6, and the lead of receiver 6 links to each other with micro computer 8 by the base plate circular hole of base 2; Loam cake 1 covers on the base 2, and uses bolt.

As shown in Figure 3, when road angle of gradient measurement mechanism is placed on the sloping road, the base plate of base 2 is parallel with sloping road, because transmitter connecting link 4 can freely swing in loam cake 1 spherical pore, swing stops back transmitter connecting link 4 under the gravity effect and remains vertically downward, the laser that receiver 6 receives generating laser 5 can be determined corresponding coordinate position, is input in the micro computer 8 by calculating head fall angle and the cross fall angle that can obtain sloping road.

The distortion of embodiment

In addition, the utility model is not limited to above-mentioned embodiment, and all distortion that can realize in the utility model purpose scope improve also being contained in the utility model.
