Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, in particular to a communication device identification method based on the longest associated separation distance. BACKGROUND

[0002] With the continuous popularity of mobile communication devices and the rapid development of Internet of Things technology, wireless communication has become an indispensable part of modern society. Because wireless networks are open, they are more vulnerable to large-scale malicious attacks than traditional networks. In order to improve their security, it is necessary to identify the communication devices connected to the wireless network. Communication device identification mainly includes location identification and identity identification. Identity identification is mainly transmitted by the communication device itself. This makes identity information easy to tamper with, so identity identification needs to be added to device identification.

[0003] The location identification of the communication device is received by the receiving station to receive the area information of the communication device, and then multiple receiving stations fuse and settle the area information. This requires that the area information received by multiple receiving stations can be correctly combined to achieve the accurate location of the communication device. However, in the prior art, when the communication device is located at a distance from multiple receiving stations that reaches the longest associated separation distance, the area information received by multiple receiving stations cannot be correctly combined, which will cause the communication device to have multiple locations, and thus the location of the communication device cannot be accurately determined. SUMMARY

[0004] The purpose of the present application is to provide a communication device identification method based on the longest associated separation distance to solve the problem of inaccurate combination of location information when the communication device is located at a distance from multiple receiving stations that reaches the longest associated separation distance.

[0005] To achieve the above purpose, the present application provides the following technical solution: a communication device identification method based on the longest associated separation distance, which is as follows:

[0006] Step one: select four receiving stations with different separation distances from the communication device from multiple receiving stations that receive the area information of the communication device, and then correctly combine the area information received by the four receiving stations to determine the accurate location of the communication device;

[0007] Step two: as the communication device moves, the accurate location of the communication device also changes, and the different points formed according to the accurate location of the communication device construct the moving track of the communication device;

[0008] Step three: when the distance between the communication device and the selected four receiving stations reaches the longest accompanying separation distance, after the area information between the four receiving stations is arranged and combined, two or more virtual position points are displayed, the virtual position points are brought into the moving track for inspection, and the qualified ones are the real position points, which are the accurate position of the communication device.

[0009] Preferably, in step one, after the multiple receiving stations receive the area information of the communication device, the ambiguous area of the position of the communication device is determined, and in step one, the four receiving stations with different separation distances from the communication device are selected, two of which are located in the ambiguous area and have the longest separation distance, and the other two are located outside the ambiguous area and have the shortest separation distance.

[0010] Preferably, when the distance between the communication device and the selected four receiving stations reaches the longest accompanying separation distance, or the distance between the communication device and one of the receiving stations exceeds the longest accompanying separation distance, it is necessary to start again to select four receiving stations with different separation distances from the communication device from the multiple receiving stations.

[0011] Preferably, when the distance between the communication device and the selected four receiving stations reaches the longest accompanying separation distance, or the distance between the communication device and one of the receiving stations exceeds the longest accompanying separation distance, it is necessary to start again to select four receiving stations with different separation distances from the communication device from the multiple receiving stations.

[0012] Preferably, when the accurate position of the communication device is single and discontinuous with the moving track of the communication device, two receiving stations are introduced to statistically analyze the height of the communication device, and then the accurate position of the communication device is reconstructed.

[0013] Preferably, the four receiving stations judge the area information to select the area information of three receiving stations to calculate the position information of the communication device, so that four position results are obtained, and when the four position results are the same point, the point is the real position point of the communication device.

[0014] Preferably, when the four position results are not unified, two receiving stations are introduced to check the four position results, and the position result meeting the checking result is the real position point of the communication device.

[0015] Preferably, when the four position results are not unified, the four position results are all set as false position points, and then the false position points are brought into the moving track, and the false position points that can form continuity with the moving track are the real position points of the communication device.

[0016] Compared with the prior art, the beneficial effects of the present application are:

[0017] 1) The present application can reduce the number of receiving stations with the maximum distance from the communication device to the maximum separation distance, and further reduce the number of virtual position points, thereby facilitating the calculation of the real position point of the communication device, by reducing the receiving stations involved in the combination of the area information of the communication device.

[0018] 2) The present application can judge the accurate position of the communication device when the distance between the communication device and the receiving station reaches the maximum separation distance, by constructing the moving track of the communication device, and then judging the continuity of the virtual position point and the moving track, and then selecting the real position point.

[0023] Embodiment:

[0024] Please refer to Figure 1 The present application provides a technical solution: a communication device identification method based on the maximum separation distance, which is as follows:

[0025] Step one: select four receiving stations with different distances from the communication device from the multiple receiving stations that receive the communication device area information. When the distance between the receiving station and the communication device is the longest and the distance is accompanied by a separation distance, and when the number of receiving stations that reach the longest distance accompanied by a separation distance from the communication device is two or more, the virtual position point of the communication device determined by the receiving station will become two or more. When the number of receiving stations that reach the longest distance accompanied by a separation distance from the communication device is four or more, the virtual position point of the communication device determined by the receiving station will become a fuzzy area. At this time, the accurate position of the communication device cannot be determined. Then, the area information received by the four receiving stations is correctly combined, and the combination method is set according to the algorithm of the receiving station. The accurate position of the communication device can be determined. The distance between the four receiving stations selected initially and the communication device does not reach the longest distance accompanied by a separation distance, so the accurate position of the communication device can be determined at this time.

[0026] Step two: as the communication device moves, the accurate position of the communication device also changes. The movement of the communication device causes the position point formed by the accurate position of the communication device to move. The movement of the position point forms a continuous line, which is the movement trajectory of the communication device.

[0027] Step three: when the distance between the communication device and the selected four receiving stations reaches the longest distance accompanied by a separation distance, the distance between one receiving station and the communication device reaches the longest distance accompanied by a separation distance, and only one virtual position point appears. When the distance between two receiving stations and the communication device reaches the longest distance accompanied by a separation distance, two virtual position points appear. When the distance between three receiving stations and the communication device reaches the longest distance accompanied by a separation distance, six virtual position points appear. When the distance between four receiving stations and the communication device reaches the longest distance accompanied by a separation distance, twenty-four virtual position points appear. When the distance between more receiving stations and the communication device reaches the longest distance accompanied by a separation distance, too many virtual position points will form a fuzzy area. The virtual position points are brought into the movement trajectory for testing. Only one virtual position point in the multiple virtual position points can have continuity with the movement trajectory. This virtual position point is the real position point, and the real position point is the accurate position of the communication device.

[0028] The multiple receiving stations in step one receive the communication device area information, and can determine the ambiguous area of the communication device position. In step one, four receiving stations with different distances from the communication device are selected, two of which are located in the ambiguous area and have the longest separation distance, and the other two are located outside the ambiguous area and have the shortest separation distance, ensuring that the communication device is located in the area formed by the four receiving stations, and the four receiving stations are divided into two groups, and the geometric relationship of the connecting line between the two receiving stations in each group is intersection.

[0029] When the distance between the communication device and the selected four receiving stations all reaches the longest accompanying separation distance, twenty-four virtual position points will appear at this time, which requires more computing power, or the distance between the virtual position point and one of the receiving stations exceeds the longest accompanying separation distance, at which time there are not enough receiving stations to combine the area information of the communication device, and both need to start again to select four receiving stations with different distances from the communication device. Re-selecting the receiving station can not only save computing power, but also ensure that there are enough receiving stations to combine the area information of the communication device.

[0030] When the receiving station is reselected, four receiving stations with the shortest separation distance from the communication device and different separation distances are selected, and the accurate position of the communication device is obtained at this time. At this time, the selected receiving station is closest to the communication device, and the communication device is surrounded inside the receiving station, so that the communication device has enough moving distance.

[0031] When the accurate position of the communication device is single and discontinuous with the movement trajectory of the communication device, the single accurate position means that the accurate position of the communication device can be determined at this time, and the real position point of the communication device is discontinuous with the movement trajectory, which means that the height of the communication device changes, and two receiving stations are introduced to detect the height of the communication device. According to the distance between the two receiving stations and the area information received by the two receiving stations, a triangle can be formed, and then the height of the communication device is calculated by using the triangle theorem, and then the accurate position of the communication device is reconstructed. The statistical result is removed from the height interference, and the real position point of the communication device is obtained.

[0032] The four receiving stations judge the area information to select the area information of three receiving stations to calculate the position information of the communication device, which will obtain four position results. When the four position results are the same point, it means that the point is the real position point of the communication device, and three receiving stations can construct the accurate position of the communication device, and one receiving station is added to verify the detection result, so as to avoid that the position information of the device is collected incorrectly due to the interference of a receiving station.

[0033] When the four position results are not unified, it indicates that the receiving station is interfered, then two receiving stations are introduced, the two receiving stations are combined with one receiving station in the other four receiving stations respectively, then the position information of the communication device is calculated again, four position results appear again, the position result measured by the interfered receiving station is different from the other three position results, one of the initial four position results is the same as the three position results measured this time, and the position result is the real position point of the communication device.

[0034] When the four position results are not unified, the four position results are set as false position points, then the false position points are brought into the moving track, the false position points which can form the continuous false position points with the moving track are the real position points of the communication device, when the distance between the communication device and the receiving station reaches the longest separation distance, the number of the receiving stations is not more than one, and this method can save the computing power.
