Embodiment Construction

[0037] Below we illustrate with the concrete application of the present invention in scenic spot as example:

[0038] What needs to be explained here is that the smart electronic tags in GPS tags can use wireless transceiver modules with different communication distances according to actual application scenarios, such as communication modules with a distance of 150 meters or 1500 meters. The communication distance of these wireless transceiver modules can be adjusted according to needs. Adjustment. In the case of limited scenic area, the short-distance module can be used.

[0039] We install a GPS tag reader at a certain distance in the scenic area, generally about 100-200 meters, and control the communication distance between these readers and GPS tags at about 80-150 meters. Readers (<3w) can be powered by solar energy or general mains power. These readers are connected to the background management computer (server) through wired (such as optical fiber) or wireless (such as...

Abstract

The invention utilizes ultra-low power consumption and ultra-long-distance sleep wakeup technology over 1500 meters to integrate a GPS module with an ultra-long-distance smart electronic tag operating in a low duty cycle mode to form a low-power smart GPS tag. The GPS tag has not only all the functions, including indoor positioning and multichannel collaborative operation of a smart electronic tag, but also a GPS-specific outdoor precise positioning function. The GPS tag does not transmit self-acquired GPS positional information by means of a mobile public network or a WiFi network, has a battery life up to 3 to 5 years, is low in cost and easy and convenient to use, and can be widely used for searching and positioning people in a variety of tourist attractions, recreational areas and cities, people management in tour groups, people search and rescue in remote areas without network coverage, and container search and positioning at large ports and freight yards.

Description

technical field [0001] The invention relates to GPS positioning and low power consumption wireless communication technology. Background technique [0002] The existing outdoor positioning technology basically uses the GPS module to collect location information, and then uses the wireless public network (GPRS or WiFi) to transmit the location information back to the background management computer to realize the location of personnel and assets. [0003] This method has the following problems: [0004] 1. In order to ensure the communication between the positioning module and the background, the GPRS in the positioning module must always be in the working state, which consumes a lot of power. In addition to the power consumption of the GPS module, the positioning terminal must use a power supply that can be charged at any time (such as mobile phones and wearable devices). This greatly limits the application of this positioning technology. [0005] 2. When this method is use...
