Embodiment 1
[0035] This embodiment provides a multi-mode car search method. The method uses a multi-mode car-finding device located on the vehicle to detect the signal that the vehicle is stolen. When the signal that the vehicle is stolen is detected, the location of the stolen vehicle is quickly started and the vehicle is restricted, and then the hand-held detector and Distributed detectors are installed inside and outside the signal blind zone to determine the actual position of the vehicle. The method can realize the accurate positioning and searching of the vehicle in the signal blind area, and can obtain the complete trajectory of the vehicle after it is stolen.
[0036] figure 1 It is a flow chart of the multi-mode car search method in this embodiment. Such as figure 1 As shown, the method includes the following steps:
[0037] S101: the multi-mode car search device detects the signal that the vehicle is stolen;
[0038] The signal of vehicle theft in this embodiment includes b...
Embodiment 2
[0070] This embodiment provides a multi-mode car-finding system, which includes: a multi-mode car-finding device located on the vehicle, distributed detectors located in and outside signal blind areas, portable hand-held detectors and a remote controller. When the vehicle is in the blind spot, it can realize the accurate positioning and search of the vehicle through the communication between all parties in the system, and can obtain the complete movement track of the stolen vehicle.
[0071] figure 2 It is a system connection diagram of this embodiment, which shows a scene where a stolen vehicle is located in a blind spot. Such as figure 2 As shown, the system of this embodiment includes a multi-mode car search device 10 located on the vehicle, a distributed detector 20 located in the blind area, a distributed detector 20' located outside the blind area, a hand-held detector 30 and a remote controller 40, though figure 2 It is not clearly shown in the figure that the han...
Embodiment 3
[0095] This embodiment provides a multi-mode car search device. The multi-mode car-finding device detects the signal that the vehicle is stolen, locates the stolen vehicle in time, and sends key information such as the location information and status information of the stolen vehicle to the hand-held detector and the remote controller. When in the blind area, it also communicates with the distributed detector in the blind area, so that the location information of the vehicle is sent to the hand-held detector and remote controller through the distributed detector, and the vehicle is detected at close range through the hand-held detector.
[0096] Figure 4 It is a schematic structural diagram of the multi-mode car-finding device 10 of this embodiment. The multi-mode car search device 10 fixed on the vehicle is interconnected with the vehicle-mounted electronic system, such as Figure 4 As shown, the multi-mode car finding device 10 of this embodiment includes: anti-disassembl...
