Embodiment 1

[0029] Such as figure 1 As shown, the wireless positioning information device of the present invention includes at least one half-work half-work wireless LAN access point 1, wherein, the half-work half-work wireless local area network access point 1 includes a wireless signal transmitter 11 , a memory 12, a processor 14, the memory 12 is provided with label information, the memory 12 is connected with the wireless signal transmitter 11 through the processor 14, and is sent at the half-work half-work wireless local area network access point 1 When transmitting the beacon frame broadcast signal, the wireless signal transmitter 11 sends out the SSID stored in the tag information in the beacon frame broadcast signal.

[0030] Further, the digital broadcast method adopts the IEEE 802.11 protocol, commonly known as the WiFi method, that is, the processor puts the stored label information in the SSID (service set identifier) ​​in the service identification number, because the SSID bro...

Embodiment 2

[0042] figure 2 shown in figure 1 A solar cell 13 is added to the half-work WLAN access point 1, and the output of the solar cell 13 is the same as the original figure 1 The semi-working wireless LAN access point 1 is connected to the power input, so that in a wide range of implementation, there is no need to pull power lines, and no special maintenance is required, and the location information service can be provided for a long time by solar power.

[0043] In most places in China, the solar system that does not follow the sun can still have an average sunshine of four hours a day throughout the year at the best elevation angle. Together with places in the north like Jiangshi, there is an average of 3.6 hours in December every year. sunshine. Therefore, it is possible to maintain the continuous operation of the half-work WLAN access point 1 without the need for a power line after being equipped with an appropriate solar cell 13 .

[0044] The semi-working wireless LAN acc...

Abstract

The invention discloses a wireless positioning information device which comprises a half-duplex WLAN (wireless local area network) access point conforming to the beacon frame broadcast mode of the 802.11 protocol and only needing transmitting rather than receiving, a memory and a solar battery, wherein the solar battery is connected with a power access end of the WLAN access point; label information is arranged in the memory; and the memory is connected with a wireless signal transmitter through a processor. The label information with the known geographical position is broadcast by the WLAN access point; after entering the signal coverage range of the half-duplex WLAN access point by use of a general WiFi (Wireless Fidelity) handheld device, a user can obtain the position information and other related information; a complete ground network is not required; the position-related content information service can be provided by use of the basic WiFi access point one-way transmitting interface; and the system is relatively cheap, and the effective range of the position information label can be planned and adjusted. Since the solar battery is adopted to provide power to the access point, the power can be supplied without depending on a power line.

Description

technical field [0001] The invention relates to the electrical field, in particular to wireless electronic communication technology, in particular to a wireless positioning information device. Background technique [0002] In the prior art, wireless positioning technology can be divided into three categories. The first category is to use the position of the access point (AP Access Point) connected to the RFID reader connected to the network to locate the RFID reader. position, and then use the positioned RFID reading head to do the second positioning of the RFID tag. The second type is not to use the position location of the network access point, but to add GPS or other wireless positioning devices to the RFID reading head to directly locate the RFID reading head, and then use the positioned RFID reading head to make RFID tags Second positioning. The above two types are all to locate the reading head first, and then use the reading head with a fixed position to locate the ...
