[0025] Example 1
[0026] figure 1 It is the structure diagram of the parking lot guidance system based on the ultra-wideband wireless positioning technology provided by the embodiment of the present invention, and the details are as follows:
[0027] An electronic license plate 1 that is attached to the vehicle and transmits ultra-wide frequency pulse signals;
[0028] At least three interconnected and synchronized base stations 2 located in the parking lot are used to receive the ultra-wideband pulse signal and upload the time when the ultra-wideband pulse signal is received;
[0029] The parking space guidance server 3 connected to the base station 2 is used for generating the real-time coordinates of the electronic license plate 1 according to the positioning algorithm and the moment of receiving the ultra-wide frequency pulse signal uploaded by each of the base stations 2, and calling the pre-stored According to the attachment position of the electronic license plate ...
Example Embodiment
[0056] Embodiment 2
[0057] This embodiment mainly describes the connection relationship between the parking space guidance server and the base station, and details are as follows:
[0058] The parking space guidance server is directly connected to one base station or multiple base stations among the at least three base stations, or the parking space guidance server is connected to one base station or multiple base stations of the at least three base stations through a data exchange device.
[0059] The synchronization between the base stations can be completed by sending a synchronization pulse from one of the at least three base stations to other base stations.
[0060] Among them, there are two connection methods between the parking space guidance server and the base station, which are detailed as follows:
[0061] The first connection method:
[0062] The parking space guidance server 3 is directly connected to one base station or multiple base stations among the at l...
