Description

Intelligent vehicle-tracing system and Intelligent car-searching method

[technical field]

The present invention relates to a kind of Intelligent vehicle-tracing system and Intelligent car-searching method, particularly a kind of Intelligent vehicle-tracing system and Intelligent car-searching method of saving electric power.

[background technology]

In large parking lot, car owner is often because space, parking lot is large when returning to parking lot, and the reason such as environment and mark are similar, direction is difficult for distinguishing is easily got lost in parking lot, finds the vehicle less than oneself.

Seek car function and utilize exactly remote control or warning device, the loudspeaker that press the button rear car can ring, and two flashing lights also can be glittering, the convenient car of oneself that finds fast in the more place of car.

Section opens up Intelligent car-searching and guiding integral system is, by the place ahead on each parking stall in parking lot, video frequency car position sense terminals is installed, image information real-time grasp shoot to parking stall, video frequency car position sense terminals by candid photograph to parking stall image information by network cable transmission, to multi-channel video processing device, carry out parking space state processing and car plate is identified, again by the network switch the number-plate number information of parking space state and identification, the automobile image information that has Parking Stall, the parking of automobile time, automobile parking positional information and central processing unit carry out communication, and finally these communications are given in the database of central processing unit and carry out unified management.Central processing unit is after receiving the parking space state of multi-channel video processing device transmission, can carry out data processing, and empty wagons figure place is upgraded to data and assign to central processing unit, central processing unit sends LED parking stall induced screen update instruction to multi-channel video processing device by network switch, by multi-channel video processing device, control LED parking stall induced screen and show, thereby realize parking stall guiding function.When car owner is when being arranged on the seeking car inquiry terminal and input the car plate of own automobile of porch, parking lot, after touch-screen reception instruction, can transfer the data of central processing unit, and on screen, show the parking lot map at the current place of car owner, on map, can indicate the seat that car owner seat of living in and its vehicle are parked, and select the best route of picking up the car to be presented on this parking lot map according to parking lot general route situation, thereby guiding car owner picks up the car.Section opens up Intelligent car-searching and guiding integral system is mainly applicable to large and medium-sized underground parking, is widely used in the large parking lots such as government house, railway station and shopping center.

But section opens up Intelligent car-searching and the image information real-time grasp shoot of guiding integral system to parking stall, relatively power consumption.And car owner must be by being arranged on seeking car inquiry terminal and just can inquiring about parking spot of porch, parking lot, comparatively inconvenience.
