Problems solved by technology

[0003] The existing scheme of locating the device based on the location information of all wireless network access points that can be scanned around the device, when there are one or more mobile routing devices that are not fixed in the wireless network access points around the device (such as smart phones with personal hotspot sharing functions, 3G routers, car routers, etc.), the positioning system will use the historical location of the mobile routing device as reference data for positioning the device, and the location of these mobile routing devices that are not fixed It is very unstable, and it is very likely that the historical location corresponds to location A, while the mobile routing device may actually be in location B. Therefore, if the historical location of the mobile routing device is used as reference data for device positioning, it will greatly affect the location. precision
[0004] It can be seen that the existing device positioning scheme needs to use the historical location of the mobile routing device as the reference data for device positioning when locating the device, so the positioning accuracy is poor

Embodiment 1

[0034] Reference figure 1 , Shows a flow chart of the steps of a device positioning method according to the first embodiment of the present invention.

[0035] The device positioning method of the embodiment of the present invention includes the following steps:

[0036] Step S102: Determine the MAC address corresponding to each wireless network access point that can be scanned by the device.

[0037] There may be multiple routing devices around the device to be positioned. When positioning the device to be positioned, the positioning system installed in the device needs to determine the wireless network access points that can be scanned around the device, and obtain access to each wireless network. The MAC address corresponding to the entry point is screened for the obtained MAC address, the historical location corresponding to each MAC address is searched from the preset database according to the screened MAC address, and the device is located based on the searched historical locat...

Embodiment 2

[0047] Reference figure 2 , Shows a flow chart of the steps of generating a MAC address blacklist according to the second embodiment of the present invention.

[0048] When locating the device, a necessary prerequisite is to have a MAC address blacklist. The MAC address blacklist can be generated by the positioning system and updated at a set time interval. It can also be pre-set by those skilled in the art and stored after being imported by the system.

[0049] Refer below figure 2 , A preferred method for the positioning system to generate the MAC address blacklist is described. The specific steps for generating the MAC address blacklist are as follows:

[0050] Step S202: The positioning system obtains MAC addresses with historical locations exceeding the preset number from the preset database.

[0051] The positioning system can be set in the device to be located, and the preset database stores multiple MAC addresses, as well as the SSID and historical location corresponding to...

Embodiment 3

[0077] Reference image 3 , Shows a flow chart of the steps of generating a MAC address blacklist according to the third embodiment of the present invention.

[0078] In the embodiment of the present invention, a preferred way for the positioning system to generate the MAC address blacklist is described. The specific steps for generating the MAC address blacklist are as follows:

[0079] Step S302: The positioning system obtains a preset SSID public keyword list.

[0080] Among them, the SSID public keyword can be manually added to the SSID public keyword list by a technician, or it can be obtained by the positioning system based on the SSID stored in the preset database.

[0081] Step S304: The positioning system filters out the MAC address corresponding to the service set identifier containing any common keyword in the list from the preset database.

[0082] After the SSID public keyword list is obtained, each SSID in the preset database is filtered through the list, and the SSID cont...

Abstract

The invention provides an equipment positioning method and apparatus. The method comprises steps of determining MAC addresses corresponding to wireless network accessing points which can be scanned by equipment; obtaining an MAC address black list, and screening the scanned MAC addresses according to the black list; according to the screened MAC addresses, searching a historical position corresponding to each MAC address in a preset database; and based on the historical positions, positioning the equipment. By the equipment positioning scheme provided by the invention, the positioning deviation caused by the historical positions of the mobile wireless network accessing points is avoided, and the positioning accuracy is improved.

Description

Technical field [0001] The present invention relates to the technical field of equipment positioning, in particular to a method and device for equipment positioning. Background technique [0002] At present, when the device is positioned without the GPS (Global Position System) positioning function enabled, the following positioning schemes are mainly used: First, the positioning system will collect and analyze the wireless network access that can be scanned around the device Point to determine the MAC (Media Access Control) address of each wireless network access point; secondly, according to the MAC address of these wireless network access points, search the database for historical location information corresponding to the wireless network access point ; Finally, the center point of the location indicated by the historical location information of these surrounding wireless network access points is determined as the current location of the device to complete the positioning of t...
