Description

Active protection device for vehicle tires

technical field

The invention relates to the field of vehicle tire protection. the

Background technique

During the driving process of the car, there may be sharp objects on the road that can puncture the car tires, such as iron nails, iron wires, sharp stones, etc. After being pierced by iron nails or other sharp objects, the tires will leak air, which will cause an explosion. Tire, the consequence that burst tire causes is often very serious, also does not have an invention to handle at this situation at present. the

Contents of the invention

The object of the present invention is to provide a device for finding sharp objects on the road surface that may puncture automobile tires, such as iron nails, iron wires, sharp stones, etc., during the running of the automobile, and promptly disposing of them. the

The invention includes a detection device, an information processing device, and a processing device for suspicious objects. The three parts of the device work through the road surface condition acquisition circuit, the image processing circuit and the display circuit respectively; the detection device is installed on the front of the vehicle body, and the infrared detection system is the detection device. The core of the infrared detection system is composed of an infrared receiver, a detector, an amplifier circuit and a filter circuit; the information processing device includes an A/D conversion circuit, a microprocessor and a memory; the processing device for suspected objects is a high-pressure water jet and an electromagnetic device , including water tank, overflow valve, one-way valve, fine filter, accumulator, hydraulic pump, electromagnetic switch valve, coarse filter, motor, fan nozzle; detection device, information processing device and processing device for suspected objects through data interface to connect. the

The working principle of this device is that the detection device works continuously. The infrared detection system in the detection device is used to collect and collect road surface information and convert it into an electrical signal. The amplifier circuit and filter circuit further process the signal output by the infrared detector. To obtain sufficient signal energy and filter out clutter; the information processing device performs accurate and real-time processing on the information collected by the detection device, judges the information according to the size and shape of road objects, identifies the suspected objects, and sends out instructions to eliminate the suspected objects Instructions, after the processing device for suspicious objects receives the instructions from the information processing device, the high-pressure liquid in the accumulator forms a jet through the nozzle to quickly remove road objects. the

Among them, the A/D conversion circuit converts the signal output by the detection device into a digital signal, which is convenient for further processing by the microprocessor. The microprocessor is used for program and data control, and realizes target recognition and command control by processing road surface information. The algorithm takes the target feature database as the core, and can set different safety levels according to the road conditions on which the vehicle is driving. When the road conditions are good, a higher safety level is adopted to ensure driving safety; Lower safety level to reduce excessive misjudgment caused by complex road conditions. the

During the whole working process, the microprocessor monitors the pressure of the accumulator in real time. Once the pressure of the accumulator is lower than the set pressure, the microprocessor sends an instruction, the motor works, and the pressure of the accumulator is replenished. The microprocessor strictly The control motor and the accumulator do not work at the same time. In the process of processing, it is necessary to ensure the safety of the vehicle and take into account the safety of other vehicles and pedestrians. the

Detailed ways

During the driving process of the car, the infrared detection system in the detection device collects road surface information on the road surface that may be touched. The infrared receiver and detector are used to collect and collect road surface information and convert it into an electrical signal. The signal output by the detector is further processed to obtain sufficient signal energy and filter out clutter; the information processing device performs accurate and real-time processing on the information collected by the detection device, and judges the information according to the size and shape of road objects. Identify objects and issue instructions to exclude suspicious objects. The A/D conversion circuit converts the signal output by the detection device into a digital signal, which is convenient for further processing by the microprocessor. The microprocessor is used for program and data control. Through the road surface information The target recognition and command control are realized by the processing of the target. Using the target recognition algorithm and taking the target feature database as the core, different safety levels can be set according to the road conditions on which the vehicle is driving. When the road conditions are good, a higher safety level is adopted to ensure driving safety; in the case of bad road conditions, a lower security level is adopted to reduce excessive misjudgments caused by complex road conditions; the detection device works continuously and transmits the signal to the information processing device. For sharp objects that may cause damage to tires, the two electromagnetic switch valves work in the left position, and the high-pressure liquid in the accumulator forms a jet through the nozzle to quickly remove road objects. the
