Detailed Description
Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a method for positioning an intelligent terminal based on 5G signals according to an embodiment of the present invention, where the intelligent terminal includes a mobile terminal such as a mobile phone, and the intelligent terminal includes a position sensor, and the method for positioning an intelligent terminal based on 5G signals according to the present invention may be used for indoor positioning as well as outdoor positioning, but is mainly used for indoor positioning, which can be obtained by referring to fig. 1, and the method for positioning an intelligent terminal based on 5G signals according to the present invention includes:
step S101: and acquiring first position information of the intelligent terminal through a 5G target communication signal corresponding to the intelligent terminal and a 5G target communication base station every preset time length, and acquiring second position information of the intelligent terminal through the position sensor.
Step S102: and acquiring a target signal state corresponding to the current 5G target communication signal, and acquiring a target weight parameter corresponding to the current 5G target communication signal according to the target signal state.
In this step, different signal states correspond to different usage scenarios. For example, in an open field, the signal interference is less, and the signal state is better. When entering a sealed space (such as an elevator), the signal state may be deteriorated due to obstruction of buildings, multipath, and the like.
The present embodiment represents signal states using channel state information reference signal received power (CSI-RSRP), and divides the signal states into 4 levels of an excellent level, a good level, a medium level, and a poor level according to the values of the CSI-RSRP. When CSI-RSRP > -95dBm (decibel-milliwatts), it indicates that the signal state is at an excellent level; when-105 dBm < ═ CSI-RSRP < -95dBm, it means that the signal state is at a good level; when-115 dBm < ═ CSI-RSRP < -105dBm, it means that the signal state is at medium level; when CSI-RSRP < -115dBm, the signal state is represented in a poor level. The Channel State Information (Channel State Information) is called CSI in the field of wireless communication, which is a Channel attribute of a communication link, and describes fading factors of signals on each transmission path, that is, values of each element in a Channel gain matrix H, such as signal Scattering (Scattering), fading or distance fading (power fading) and distance fading (distance) Information. The CSI may adapt the communication system to the current channel conditions, providing a guarantee for high reliability and high rate communication in a multi-antenna system.
In this step, the value of the weight parameter needs to be dynamically adjusted according to the signal state. When the signal state is good, the weight occupied by the position information obtained by the 5G target communication signal is larger, otherwise, the weight is reduced. The specific weights are set as follows: the target weight parameter is set to 1 when the signal condition is of a good grade, set to 0.5 when the signal condition is of a good grade, and set to 0 when the signal condition is of a medium or poor grade.
Step S103: and according to the target weight parameter, performing weighted summation operation on the first position information and the second position information to obtain the current target position information of the intelligent terminal.

(x-x1)2+(y-y1)2+(z-z1)2＝d1 2---(1)；
(x-x2)2+(y-y2)2+(z-z2)2＝d2 2---(2)；
(x-x3)2+(y-y3)2+(z-z3)2＝d3 2---(3)；
wherein d is ZhiThe distance between the terminal and the communication base station, d is obtained by calculating the relation between the signal intensity of the communication base station and the environmental attenuation factor, d1Is the distance between the intelligent terminal and the first communication base station, d2Is the distance between the intelligent terminal and the second communication base station, d3The distance between the intelligent terminal and the third communication base station.
