Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] The invention provides a low-cost position sensing system, which can be widely used in vehicle anti-theft, prevention of personnel loss, and centralized management of crowds and vehicle groups. By using the existing wireless communication network, the location of the positioning target is realized. Change tracking.

[0051] Such as figure 1 As shown, the sensing terminal 100 is generally attached to a positioning target, such as being installed on a vehicle or a safe or other items, or carried on the body of an elderly person or a child. The sensing terminal 100 receives the wireless signa...

Abstract

The present invention is applicable to the field of wireless communication and provides a position induction system, equipment and method. The described system includes; induction terminal, it is used for monitoring service quarter change-over information, reading quarter marker of current service quarter, according to the quarter marker of current service quarter monitoring position change of positioned object and outputting position change information of positioned object; wireless network, it is used for sending wireless signal to the described induction terminal, controlling the described induction terminal and executing quarter change-over; and receiving device, it is used for receiving position change information of described positioned object.

Description

technical field [0001] The invention belongs to the field of wireless communication, in particular to a system, device and method for position sensing of a positioning target through a wireless network. Background technique [0002] With the popularity of vehicles, vehicle theft has become a growing problem, and one way to solve this problem is to attach a device to the vehicle that can track the vehicle's position changes. [0003] In the prior art, the vehicle can be positioned by GPS (Global Positioning System). The accuracy of GPS positioning is relatively high, within 10 meters, even at the level of centimeters and millimeters, but the cost of equipment is high and it is difficult to Widespread application. It is also possible to perform ranging and positioning through multiple base stations. The accuracy depends on the cell. It can reach 200 meters or even higher in the center of the city. However, this solution has high operating costs. Greater impact. Contents of...
