Detailed description of the invention
As shown in Figure 1 or 2, this utility model includes 1 light rain collection box and 1 light rain brush panel；Light rain collection box is arranged on Herba Plantaginis windshield, detects steam material on glass by its optical element carried.Light rain collection box includes rain collection module, light collection module, acquisition control module, the first wireless module and power management module；Other four modules that described power management module is light rain collection box provide power supply, described rain collection module and light collection module electrically connect with acquisition control module respectively, described rain collection module gathers the rainfall data of windshield, the intensity of illumination of described light collection module monitors car external environment light, acquisition control module generates control instruction according to rainfall data and light intensity data, and send control instruction to light rain brush panel by the first wireless module, described light rain brush panel includes that light rain brush drives module, drive control module and the second wireless module, second wireless module connects drive control module, drive control module receives the control instruction of acquisition control module transmission and exports driving instruction to light rain brush driving module, light rain brush drives module can drive car bulb and rain brush.Light rain brush drives module to be mainly controlled car bulb and rain brush by relay and drive circuit, and light rain brush drives module to be directly connected to light and the rain brush of automobile, it is not necessary to automobile line carries out the change of complexity.
Described rain collection module uses mode detection current environment light and the situation of rainfall of interval timing wake-up.
Described rain collection module includes infrared-emitting diode, the first lens, infrared receiving diode and the second lens；Described infrared-emitting diode and infrared receiving diode electrically connect with acquisition control module respectively, the Infrared of the assigned frequency that described infrared-emitting diode is launched is irradiated in windshield after the first lens are adjusted to parastate, described second lens receive through the Infrared of assigned frequency of windshield reflection and are again adjusted to parastate, and the reception of described infrared receiving diode is again adjusted to the Infrared of the assigned frequency of parastate through the second lens.
The wavelength of the Infrared that described infrared-emitting diode is launched is 800 ~ 1000nm.
Described acquisition control module combines fast filtering algorithm and retains useful data to filter invalid data in rainfall size percentage rate ratio and intensity of illumination data, judge different rainfall patterns and the different ambient light patterns such as light rain, moderate rain, heavy rain based on useful data according to the rainfall set and luminosity threshold values again, and then judge whether to need to send rain brush and the control instruction of light to light rain brush panel.
Described power management module includes solar panels and built-in energy storage battery, and described solar panels are connected with built-in energy storage battery.It is powered by solar panels and internal battery self-circulation system, facilitates user's change the most voluntarily to collection point.
Described acquisition control module and drive control module all use low-power scm, and specific in the present embodiment, it is low-power consumption SMT8 processor that described acquisition control module and drive control module all use.
Described first wireless module and the second wireless module are all bluetooth 4.0 modules.Bluetooth 4.0 module, beneficially data over distance is used to forward, the problem solving to need again automobile to be connected up.
Operation principle of the present utility model is as follows:
As in figure 2 it is shown, in light rain collection box, it is the Infrared being sent extraordinary frequency by internal infrared-emitting diode that rain collection module carries out the principle of rain collection, is adjusted to directional light state through the first lens and is irradiated on windshield.When glass is dried, Infrared will be totally reflected, and be again adjusted to directional light state through the second lens and received by infrared receiving diode, and the rainfall size percentage rate ratio that acquisition control module obtains is maximum 100% of its output.When on glass rain, raindrop due to refraction index changing, Infrared can not be totally reflected, but regard water droplet size and occur partially reflective, now infrared receiving diode only receives partially reflective optical signal, now, the rainfall size percentage rate ratio that acquisition control module obtains is less than the maximum of its output.And the environment illumination intensity data outside light collection module monitors car.And then the acquisition control module with low-power consumption STM8 processor as control core is according to rainfall size percentage rate ratio and environment illumination intensity data, and combine fast filtering algorithm to filter invalid data and to provide useful data, judge different rainfall patterns and the different ambient light patterns such as light rain, moderate rain, heavy rain further according to the rainfall set and luminosity threshold values, then judge whether to need to send rain brush and signal light control request signal to light rain brush panel.If needing to be controlled, acquisition control module goes to select corresponding rain brush gear and signal light control function code to generate control instruction with ambient light patterns according to rainfall pattern, finally drives the first wireless module that control instruction is sent to the request of light rain brush panel and controls rain brush and light.Light rain collection module uses the pattern of interval timing wake-up to carry out detecting current environment light and the situation of rainfall, in this mode of operation, significantly lowers the use power consumption of whole control device.
Light rain brush panel receives control instruction by the second wireless module, drive control module with low-power consumption STM8 processor as control core carries out data decoding conversion and is reduced into rain brush gear and the signal light control function code of correspondence control instruction, and then generation driving instruction, described Wiper motor selects rain brush gear according to rain brush shift function code from default interval shelves, the continuous shelves of low speed and high-speed and continuous shelves, and car bulb controls being turned on and off of car light according to signal light control function code.
Above example scheme mainly solves vehicle body and installs a wiring difficult problem for rainfall/sunlight sensor, and realizes rain brush, the automatically controlling of headlight, thus adds and drive the comfort level of driving and decrease vehicle body potential safety hazard.
But it should be recognized that the concrete technical characteristic that above scheme is previously mentioned in implementing, in the case of the most conflicting, without departing from thought technical scheme of the present utility model, it can be all answered to be considered as content belonging to this utility model by any type of combination.
