Description

Technical Field

[0001] The present disclosure relates to the field of positioning technology, and in particular to a method, device, equipment and medium for positioning and screening and matching personnel in an exhibition. Background Art

[0002] In recent years, with the vigorous development of "Internet of Things" technology, various spatial location positioning technologies and related systems are developing rapidly. At present, the "GPS" positioning system and the "Beidou" positioning system are widely used in positioning and navigation. However, due to the shielding of buildings, the signal strength of the above two positioning systems is greatly attenuated, which seriously affects the indoor positioning accuracy. Therefore, how to achieve precise indoor positioning has become an important research topic in various fields and research institutions.

[0003] At present, the more mainstream indoor positioning methods mainly include: ZigBee technology, UWB technology, wireless LAN technology and Bluetooth technology. ZigBee technology has the advantages of good penetration and low energy consumption, but it is easily interfered with and has low positioning accuracy, so the positioning system is difficult to popularize; wireless LAN technology has the advantages of low deployment cost and simple algorithm, but its signal is easily interfered with, and Wi-Fi beacons need to be connected to a wired power supply during deployment, which limits its application; UWB positioning technology has high energy consumption and high cost, and requires specific tags (compared to mobile phones and other terminals which are natural tags); the advantage of Bluetooth technology is that the device is small and can be integrated into tiny mobile terminals. With the development of Bluetooth technology, the power consumption is lower, the transmission distance, stability and security have been greatly improved, and it has great advantages in indoor positioning.

[0004] In certain indoor scenarios, such as large-scale exhibitions, indoor technology is not yet popular, and more traditional technical means are still used. Some large-scale exhibitions do not even involve the application of indoor positioning technology, which greatly limits the cooperation between exhibitors and exhibition organizers.

[0074] The technical solution of the present disclosure is described in detail with specific embodiments below. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0075] Figure 1 The flowchart of the method for locating and screening people in an exhibition according to the embodiment of the present disclosure is shown as an example. Figure 1 As shown, the method includes:

[0076] S101, based on a pre-installed positioning base station, obtaining the location information and / or movement trajectory of each target node in the environment where the positioning base station is located, wherein:

[0077] The target node includes a node that has been pre-registered with Bluetooth and has a wireless communication function;

[0078] Exemplarily, the embodiments of the present disclosure take exhibitions as exemplary application scenarios. In actual applications, users can wear badges integrated with Bluetooth modules. When users enter the venue, guest data is collected through a Bluetooth scanner, and the collected data is sent to a cloud server in real time to provide instant dynamic reports.

[0079] In an optional embodiment,

[0080] The method for obtaining the location information of each target node in the environment where the positioning base station is located based on the pre-installed positioning base station includes:

[0082] Determine the signal strength of the wireless signal and the arrival time of the wireless signal based on the wireless signal of each target node;

[0083] Determine the arrival angle between each target node and the positioning base station according to the signal strength and the arrival time;

[0084] The location information and / or movement trajectory of each target node is determined according to a pre-trained indoor positioning model through the arrival angle between each target node and the positioning base station and the signal strength of the wireless signal.

[0085] Exemplarily, a positioning base station may be pre-installed in the exhibition, wherein the positioning base station is used to acquire wireless signals of various target nodes in the exhibition environment, and determine the location information and / or movement trajectory of each target node based on the wireless signals of the target nodes.

[0086] Figure 2 A schematic diagram exemplarily shows the first positioning method of the embodiment of the present disclosure, as shown in FIG. Figure 2 As shown in the figure, MS represents the target node, BS1-BS3 represent base stations, and the three base stations can measure the distances from the MS, which are r1-r3 respectively. With the measured distances of each base station as the center, three circles are drawn, and their intersection is the position of the MS. When the three base stations are all LOS base stations, the estimated position of the MS can generally be calculated according to the least squares (LS) algorithm.

[0087] The method for calculating the estimated position of the MS may be as follows:

[0088]

[0089] Where x represents the horizontal coordinate of the base station, y represents the vertical coordinate of the base station, and r i represents the radius of the circle corresponding to the base station, N represents the number of base stations or target nodes, x i Indicates the horizontal coordinate of the i-th node, y i Represents the vertical coordinate of the i-th node.

[0090] Expanding the above formula, we can get the following formula (2):

[0091]

[0092] The following formula (3) can be obtained by the least squares method:

[0093] X=(A T A) -1 A T Y

[0094] Figure 3 A schematic diagram exemplarily shows a second positioning method according to an embodiment of the present disclosure, as shown in FIG. Figure 3 As shown in the figure, MS represents the target node, BS1-BS2 represent base stations, and the arrival angle between the signal mobile station and the base station is measured. The ray formed with the base station as the starting point must pass through the mobile station, and the intersection of the two rays is the position of the mobile station. This method only requires two base stations to determine the estimated position of the MS.

[0095] Exemplarily, the embodiment of the present disclosure may determine the estimated position of the MS through TOA / AOA hybrid positioning, and the embodiment of the present disclosure will not be described in detail herein.
