Abstract

The invention discloses a wireless coverage system applied to a parking lot, which comprises a plurality of APs arranged in the parking lot, wherein the APs at least comprise a directional AP, and theradiation direction of the directional AP is the same as or approximately the same as the direction of a channel in the parking lot. According to the wireless coverage system applied to the parking lot, the directional AP and the omnidirectional APs are combined with the parking lot environment to carry out wireless coverage, positioning and navigation in the parking lot can be realized by usingfewer APs, the planning difficulty of AP layout can be effectively reduced, the use number of APs is reduced, the layout density of the APs is reduced, the wireless coverage cost of the indoor parkinglot is effectively saved, and the method is suitable for large-scale popularization and application.

Description

Technical field

[0001] The invention belongs to the field of parking facilities, and in particular relates to a wireless coverage system applied to parking lots. Background technique

[0002] At present, with the development of the city and the automobile industry, more and more attention has been paid to the facilities in the parking lot. In the indoor parking lot, due to the weak satellite positioning signal, it is necessary to perform positioning through Bluetooth, AP (wireless access point), etc., and realize indoor navigation in the parking lot through positioning. In order to ensure the accuracy of positioning, AP positioning usually requires a terminal device to obtain the signal strength of at least three APs, and then determine the location of the terminal device through three or more APs. The AP used in this solution is an omnidirectional AP, which requires a great deal of energy to calculate the placement position of the AP, and the density of the deployed AP is relat...

Embodiment Construction

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0020] Reference Figure 1-2 , Figure 1-2 This is a schematic diagram of the first embodiment of the wireless coverage system applied to the parking lot of the present invention. The wireless coverage system is applied to the parking lot. The wireless coverage system 10 includes several AP1, switch 2 and server 3, and AP1, switch 2 and server 3 in sequence Communication connection, among them, AP1 is arranged in the parking lot.

[0021] Wherein, AP1 includes an omnidirectional AP (not shown in the figure) and at least a certain direction AP11. The directional AP11 is installed on the top of the parking lot and located above the passage. The radiation direction of the directional AP11 is the same or similar to the direction of the passage in the parking lot. the same. Among them, because the directional AP radiat...
