Abstract

The invention discloses an active prevention device for vehicle tires, which can be used for timely finding and getting rid of iron nails, iron wires and pointed stones and other pointed and sharp objects on a road, which can puncture vehicle tires, during the running of a vehicle. The active prevention device comprises a detection device, an information processing device and a suspect treatment device which work respectively through a road condition acquisition circuit, an image processing circuit and a displaying circuit, wherein the detection device is installed at the front part of a vehicle body, an infrared detection system is a core of the detection device and consists of an infrared receiver, a detector, an amplification circuit and a filtering circuit; the information processing device comprises an A/D conversion circuit, a microprocessor and a memorizer; the suspect treatment device mainly refers to a high-pressure water jet and electromagnetic device which comprises a water tank, an overflow valve, a one-way valve, a fine filter, an energy accumulator, a hydraulic pump, an electromagnetic switch valve, a rough filter, a motor and a fan-shaped nozzle; and the detection device, the information processing device and the suspect treatment device are connected through data interfaces.

Description

Tire for vehicles is protective device initiatively

Technical field

The present invention relates to tire for vehicles protection field.

Background technology

In the vehicle traveling process; Possibly have the sharp object that punctures motor tire on the road surface, like iron nail, iron wire, sharp stone etc., after by iron nail or other sharp object punctures; The tire phenomenon that can leak air; And then cause and blow out that the consequence that causes is often very serious, does not also have an invention to handle to this situation at present.

Summary of the invention

The present invention seeks to find may puncture on the road surface sharp object of motor tire in order to provide a kind of in vehicle traveling process, like iron nail, iron wire, sharp stone etc., and to its device of in time handling.

The present invention includes detector, signal conditioning package, to the processing equipment of doubtful thing, three partial devices are carried out work through condition of road surface Acquisition Circuit, image processing circuit and display circuit respectively; Detector is installed in body forward structure, and IRDS is the core of detector, and IRDS is made up of infrared remote receiver, detector, amplifying circuit and filter circuit; Signal conditioning package comprises A/D change-over circuit, microprocessor and memory device; Processing equipment to doubtful thing is high-pressure water jet and calutron, comprises water tank, by pass valve, check valve, fine filtering, energy storage, Hydraulic Pump, electromagnetic switch valve, coarse filtration, motor, fan nozzle; Detector, signal conditioning package are connected through data-interface with processing equipment to doubtful thing.

The principle of work of this device is that detector carries out uninterrupted duty; IRDS in the detector is used to compile, gather information of road surface; And convert electric signal to; Amplifying circuit and filter circuit are further handled the signal of infrared detector output, to obtain enough signal energies and filtering clutter; Signal conditioning package carries out accurately handling in real time to the information of detector collection; Size, shape according to the road surface object are judged information; Discern for doubtful thing; And send the instruction of getting rid of doubtful thing, the processing equipment of doubtful thing is received the instruction that signal conditioning package sends after, the highly pressurised liquid in the energy storage forms jet through nozzle and gets rid of the road surface object rapidly.

Wherein the A/D change-over circuit converts the signal of detector output into digital signal, is convenient to the further processing of microprocessor, and microprocessor is used for program and Data Control; Realize target recognition and instruction control through the road pavement information processing; Utilizing Target Recognition Algorithms is core with the target signature data bank, the different security rank can be set, according to the condition of road surface of vehicle ' in the good driving process of road conditions; Take higher level of security, guarantee the safety of going; Under the bad situation of road conditions, take lower level of security, to reduce the too much erroneous judgement that complicated road surface situation causes.

Microprocessor is monitored the pressure of energy storage in real time in entire work process; In case the pressure of energy storage is lower than setting pressure, microprocessor sends instruction, machine operation; Energy storage is carried out pressure to be replenished; Microprocessor strict control motor and energy storage are not worked simultaneously, in treating process, should guarantee this car safety, take into account the safety of considering other vehicles and pedestrian again.

The specific embodiment

In the automobile traveling process; Through the IRDS in the detector information of road surface collection is carried out on the road surface that possibly contact; Infrared remote receiver and detector are used to compile, gather information of road surface; And converting electric signal to, amplifying circuit and filter circuit are further handled the signal of infrared detector output, to obtain enough signal energies and filtering clutter; Signal conditioning package carries out accurately real-time processing to the information of detector collection, according to size, the shape of road surface object information is judged, discerns for doubtful thing; And the instruction of sending the doubtful thing of eliminating; Wherein the A/D change-over circuit converts the signal of detector output into digital signal, is convenient to the further processing of microprocessor, and microprocessor is used for program and Data Control; Realize target recognition and instruction control through the road pavement information processing; Utilizing Target Recognition Algorithms is core with the target signature data bank, the different security rank can be set, according to the condition of road surface of vehicle ' in the good driving process of road conditions; Take higher level of security, guarantee the safety of going; Under the bad situation of road conditions, take lower level of security, to reduce the too much erroneous judgement that complicated road surface situation causes; Detector carries out uninterrupted duty; And pass the signal along to signal conditioning package; In case find the pricking object that possibly damage tire, two electromagnetic switch valves get into the work of position, a left side, the highly pressurised liquid in the energy storage forms jet through nozzle and gets rid of the road surface object rapidly.
