Summary of the invention
Technical matters to be solved by this invention realizes a kind of system that can shift to an earlier date the removal front windshield frosting of hot car and accumulated snow.
To achieve these goals, the technical solution used in the present invention is: automobile window glass pre-cleaning system, the control unit of this system is provided with independently auxiliary power, described auxiliary power is charged by electric generator of vehicle, be arranged on the laser detector on operator's compartment console and the front windshield reflectivity signals of collection is delivered to control unit, the temperature sensor gathering the outer temperature of car exports the outer temperature signal of car to control unit, described control unit is through the mobile communication of communication unit and user, described control unit outputs control signals to key start unit and an air-conditioning unit of vehicle.
Described laser detector is at least provided with two, and is installed in below front windshield, and the laser vertical that described laser detector is launched injects front windshield, and receives the signal reflected by front windshield.
Control method based on described automobile window glass pre-cleaning system:
Step 1, user are by mobile phone and communication unit communication and arrange system startup plan;
Step 2, according to startup plan open system;
If step 3 laser detector show that front windshield reflectivity is greater than default reflex threshold, simultaneously the outer temperature of car is less than or equal to 0 degree Celsius, then export vehicle launch signal to key start unit and start vehicle, otherwise perform step 6;
Step 4, unlatching air-conditioning heating, and open air-conditioning Inner eycle pattern;
Step 5, operation Preset Time;
Step 6, closedown air-conditioning unit, vehicle are flame-out, shutdown system.
Described step 3, in step 4 process, opens air-conditioning unit after postponing time rating after vehicle launch.
In described step 3, if be provided with at least two laser detectors, if there is one or more laser detector show that front windshield reflectivity is less than or equal to default reflex threshold, be then judged to be no, perform step 6.
Described startup plan comprises time opening system or open system at once.
Described mobile phone is provided with timing reminding function, described timing reminding function be within a definite time with the alarm in moment.
The system of the invention has the advantages that can shift to an earlier date hot car before car owner arrives parking stall, and effectively remove freezing and accumulated snow of front windshield, save the time of the large calorimetric car of car owner and defrosting/snow, and before vehicle travels in the winter time, ensure the preheating of driving engine, be conducive to the life-span of improving driving engine, keep the super performance of driving engine.
Detailed description of the invention
As shown in Figure 1, automobile window glass pre-cleaning system, this system is provided with control unit, and control unit is used for analyzing and processing data information, whole automobile window glass pre-cleaning system is controlled, control unit is provided with independently auxiliary power, because system needs continual and mobile communication, according to storage battery, then there is feed risk, auxiliary power is charged by electric generator of vehicle, the power supply of support system, has also ensured the normal use of vehicle.
Be arranged on the laser detector on operator's compartment console and the front windshield reflectivity signals of collection is delivered to control unit, laser detector is at least provided with two, and be installed in below front windshield, the laser vertical that laser detector is launched injects front windshield, and receive the signal reflected by front windshield, due to accumulated snow and the icing reflectivity that can increase front windshield, and it is lower with the glass-reflected rate of freezing without accumulated snow, by arranging suitable reflectivity threshold value, can measure accurately and freeze or occur accumulated snow, and arrange multiple, can avoid because the external factors such as fallen leaves are on the impact of detection.
When temperature is higher, glass may produce fog or condensation, fog and condensation also can increase the reflectivity of glass, the accuracy of measurement of laser detector is impacted, therefore the temperature sensor gathering the outer temperature of car exports the outer temperature signal of car to control unit, can accurately be judged by temperature, whether condensation or fog can freeze.
Control unit is through the mobile communication of communication unit and user, and realize Long-distance Control, control unit outputs control signals to key start unit and an air-conditioning unit of vehicle, then can control vehicle air conditioning and heat, then can remove in advance and freeze and accumulated snow.
Control method based on above-mentioned automobile window glass pre-cleaning system:
Step 1, user are by mobile phone and communication unit communication, and user can send instruction by mobile phone to communication unit, arrange the system startup plan of control unit;
Startup plan comprises time opening system or open system at once, in addition, in order to improve the hommization function of system, mobile phone is provided with timing reminding function, timing reminding function be within a definite time with the alarm in moment, whether morning (7 point) reminding user such as setting working day (Mon-Fri) wants open system, guarantees that user can use native system in time, effectively and reasonably;
Step 2, according to startup plan open system; Time opening, then reach setting-up time and automatically open, or open at once;
Step 3, system have determined whether frosting or accumulated snow, if laser detector show that front windshield reflectivity is greater than default reflex threshold, the outer temperature of car is less than or equal to 0 degree Celsius simultaneously, then export vehicle launch signal to key start unit and start vehicle, otherwise perform step 6;
If be provided with at least two laser detectors, if there is one or more laser detector show that front windshield reflectivity is less than or equal to default reflex threshold, be then judged to be no, perform step 6, reducing erroneous judgement may;
Step 4, unlatching air-conditioning heating, and open air-conditioning Inner eycle pattern; Step 3, in step 4 process, opens air-conditioning unit after postponing time rating after vehicle launch, improves engine preheating speed, is conducive to energy efficient, and before the non-heat engine of driving engine, is also cold wind, cannot reach the effect raising front windshield temperature;
Step 5, operation Preset Time, such as, run ten minutes;
Step 6, closedown air-conditioning unit, vehicle are flame-out, shutdown system.
After system closing, because vehicle interior temperature is higher, also can not freeze very soon, timely user's setting-up time is not too accurate, also can not have influence on the effect of defrosting snow removing, also can reach warm-up the engine rated functional simultaneously.
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 improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
