Example 1

The embodiment provides a dust load valid data extraction system. Referring to fig. 1, a schematic diagram of a dust load effective data extraction system provided by the present invention is shown, and the system includes a color sensor emitting module, a color sensor receiving module, and a data processing module. The color sensor transmitting module is connected with the receiving module, and the other end of the receiving module is connected with the data processing module. The color sensor transmitting module and the color sensor receiving module are installed at a position suitable for monitoring the color of the tire, for example, at the front position of a fender tile of each tire, as shown in fig. 2. The color sensor emitting module emits light beams at a fixed angle towards the direction of the wheel, the installation direction of the color sensor receiving module is consistent with that of the emitting module, and the emitting module and the receiving module are not in direct contact with the tire.

The color sensor emitting module emits light beams to the surface of the tire, the light beams formed on the surface of the tire are reflected to the receiving module, and the data processing module can judge whether the current road surface contains water according to different spectral intensities received by the receiving module, so that the judgment on the dust load monitoring data at the moment is made. Because the receiving module receives different spectral intensities of the dry and wet tires, the data processing module restores the spectral intensities of the tires into corresponding color data, and the color of the tires can be measured.

The embodiment also provides a dust load effective data extraction method. Referring to fig. 3, a flow chart of a method for extracting effective data of dust load provided by the present invention is shown, which includes the following steps:

step 301: when the dust load monitoring equipment is operated, the color sensor emitting module emits a light beam to the surface of the tire;

step 302: the color sensor receiving module receives reflected light from the tire surface;

step 303: the data processing module extracts spectral intensity from the reflected light received by the color sensor receiving module;

step 304: the data processing module judges whether the spectrum intensity is within a numerical range a, if so, the step 305 is carried out, otherwise, the step 306 is carried out;

step 305: when the road surface is water, the collected dust load data has deviation, so the monitored dust load data is removed, and the road surface containing water is marked;

step 306: and judging that the monitored dust load data is valid, and extracting.

Preferably, the humidity sensor is mounted to point in the direction of travel of the vehicle at a height of one-half of the distance of the tire from the ground.

When the vehicle runs on a water-containing road surface, water drops are thrown to the position of the humidity sensor through rotation of the tire, the humidity sensor receives the water drops and sends the generated humidity signal to the data processing module, the data processing module converts the humidity signal into a humidity value and judges whether the value is within a value interval c of the water content of the road surface, and therefore whether the current road surface contains water is judged, and judgment is made on the acceptance of dust load monitoring data at the moment.

step 603: the data processing module judges whether the humidity value is within a value interval c, if so, the step 604 is executed, otherwise, the step 605 is executed;

step 604: when the road surface is water, the collected dust load data has deviation, so the monitored dust load data is removed, and the road surface containing water is marked;

step 605: and judging that the monitored dust load data is valid, and extracting.

Wherein, the numerical range c is the water-containing numerical range of the road surface, and the range can be 1-100, so that the water drop amount thrown up by the tire is accurately calibrated; when the tire is dry, the data measured by the data processing module is 0 when no water is attached to the surface of the tire; when the road surface is wet and water adheres to the surface of the tire, and water drops are thrown to the humidity sensor, the data measured by the data processing module is 1-100.

More excellent, at the actual motion in-process, the vehicle is gone through dry road surface again behind the wet road surface, and the water droplet gets rid of humidity transducer department after, needs the longer time just can dry, can lead to effective data loss. The rear end of the humidity sensor is provided with a heating module which can be composed of PTC heating sheets, and when the value measured by the data processing module is in the range of 1-100, the heating module is started to evaporate water within 3s, so that the monitoring data is the real-time value of throwing water drops on the road surface.
