In order to solve the problem of missing position information, an inertial navigation device or a triangulation method is usually adopted to perform point compensation on the missing position information, but the accuracy of point compensation in the later period is low.
Therefore, how to obtain the position of the terminal at the time when the position information is lost and improve the accuracy of the obtained position information become problems to be solved urgently.

Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Referring to fig. 1, fig. 1 is a schematic flow chart of a position location method according to an embodiment of the present invention.
As shown in fig. 1, the position locating method includes steps S101 to S103.
Step S101, receiving the position request information sent by the first terminal, and acquiring the position information of the second terminal based on the position request information.
The first terminal is a terminal which fails to collect the position information, and the second terminal is a terminal which can normally collect the position information.
When the terminal fails to collect the position information, the terminal serves as a first terminal to send position request information, and the position information of a second terminal is obtained based on the position request information.
In a specific implementation process, after the first terminal sends the location request information, each second terminal may obtain its own location information based on the location request information, so as to calculate the location information of the first terminal. Or the cloud end can respectively acquire the position information of each second terminal based on the position request information, so as to calculate the position information of the first terminal.
It is understood that the number of the first terminal and the second terminal may be plural. When the number of the first terminals is multiple, each first terminal sends a position request message, and after receiving the position request message, the position information of each second terminal is obtained, so that the position information of the first terminals can be calculated conveniently.
In a specific implementation process, the location information includes a MAC address, an IP address, a collection time of the location information, and location information collected at each collection time of the second terminal, where the location information collected at each collection time of the second terminal is geographical location information including a location longitude and a location latitude.
It is to be understood that, in the present application, when the position information of the first terminal is calculated based on the position information of the second terminal, the calculated position information of the first terminal is also geographical position information. In the calculation process, address information such as the MAC address and the IP address of the second terminal does not participate in data calculation.
In an embodiment, the location request information includes a starting time when the first terminal fails to acquire the location information; acquiring the position information of the second terminal based on the position request information, comprising: and acquiring a plurality of pieces of position information of the second terminal before the starting time based on the starting time.
The location request information includes a starting time when the first terminal fails to acquire the location information, that is, at which time the first terminal starts to acquire the location information abnormally. In a specific implementation process, the location request information may further include information such as a failure reason for failure in acquiring the location information and an IP address of the first terminal. For example, the reason for failure to collect location information may be that the GPS signal is weak.
When the position information of the second terminal is obtained, the position information may be obtained based on a starting time at which the first terminal cannot obtain the position information, that is, a plurality of position information collected by the second terminal before the starting time is obtained.
In one embodiment, the position information includes position information of the start time and a plurality of consecutive position information before the start time. That is, the acquired location information of the second terminal includes location information acquired by the second terminal at a start time when the first terminal cannot normally acquire the location information, and a plurality of continuous location information acquired by the second terminal before the start time.
For example, when the first terminal cannot normally acquire the location information from time T0, the starting time is time T0, and the location information acquired by the second terminal at time T0 and the location information acquired by the second terminal at several consecutive acquisition times before time T0 are acquired.
And step S102, calculating the sharing weight of the second terminal according to the position information of the second terminal.
After the position information of the second terminal is acquired, the sharing weight of the second terminal may be calculated according to the position information of the second terminal. The sharing weight refers to a capability weight of the second terminal contributing its own location information to the first terminal.
Because in the continuous smaller time window, the object is in the state of uniform motion. Whereas, generally speaking, the time interval between two adjacent acquisition instants of the second terminal is the same. For example, the second terminal collects position information at time T0, time T0+1 and time T0+2, respectively, and the time intervals between the three collection times are the same.
Therefore, it can be theoretically assumed that the moving distances of the second terminal between adjacent acquisition instants should be equal. That is, the moving distance D1 of the second terminal from time T0 to time T0+1 should be equal to the moving distance D2 of the second terminal from time T0+1 to time T0+2, i.e., D1 is equal to D2.
In consideration of the time-varying property of the GPS signal and the surrounding environment, the position information from the same terminal acquired at the same geographic position has time-domain fluctuation, that is, the position information of the second terminal has certain fluctuation. Thus, the sharing weight of the second terminal may be determined based on the change in the movement distance of the second terminal between the respective acquisition instants over a period of time.
If the change of the movement distance of the second terminal between the acquisition moments is larger, the accuracy of the position information acquired by the second terminal is considered to be not high, and correspondingly, the sharing weight of the second terminal is lower. On the contrary, if the change of the movement distance of the second terminal between the acquisition moments is smaller, the accuracy of the position information acquired by the second terminal is considered to be higher, and correspondingly, the sharing weight of the second terminal is higher.
In an embodiment, since each second terminal has a plurality of collected position information, the change state of the collected position information is different according to the difference of the motion state of the second terminal.
For example, when the moving speed of the second terminal is fast, the position of the second terminal changes more sharply, and when the moving speed of the second terminal is slow, the position of the second terminal changes more gently.
Therefore, in order to reduce the amount of calculation and improve the accuracy of the result of calculation, different amounts of position information can be selected from the collected position information according to the motion state of the second terminal for calculation, thereby ensuring that the sample point contribution can be more accurately positioned in the high-speed motion state.
For example, if the second terminal collects N pieces of location information, where N is greater than or equal to 1, when the moving speed of the second terminal is slow, the location change of the second terminal is not obvious, and therefore, less sample location information can be selected from the N pieces of location information for calculation. At the time of selection, random selection or other selection methods may be adopted.
When the moving speed of the second terminal is higher, the position change of the second terminal is more obvious, so that more position information can be selected from the N position information for calculation, and the position sharing precision is improved.
In an embodiment, please refer to fig. 2, and fig. 2 is a flowchart illustrating sub-steps of a position location method according to an embodiment of the present invention. Step S102 includes sub-step S1021 and sub-step S1022.
And a substep S1021, calculating a position weight of the second terminal according to the position information of the second terminal.
The position weight refers to the fluctuation of the movement distance of the second terminal between the acquisition moments, and specifically, the position weight may be determined by calculating a standard deviation of a position change of the second terminal.
In one embodiment, calculating the location weight of the second terminal according to the location information of the second terminal includes: determining a position change standard deviation of the second terminal according to the position information of the second terminal; and carrying out normalization processing on the position change standard deviation to obtain the position weight of the second terminal.
In a specific implementation process, a plurality of pieces of location information of the second terminal may be acquired, and then the standard deviation of location change of the second terminal may be determined according to the acquired plurality of pieces of location information. The position variation standard deviation refers to a distance variation standard deviation of a moving distance of the second terminal between the respective acquisition moments.
For example, when the first terminal cannot normally acquire the position information from the time T0, the position information acquired by the second terminal at K sampling times before the time T0 is acquired, and the moving distance of the second terminal between two adjacent acquisition times is calculated based on the K position information to calculate the position change standard deviation according to the moving distance.
In a specific implementation process, the calculation formula of the standard deviation of the position change may be:
where σ denotes a standard deviation of a position change, K denotes a sampling time, and d (t)i) The motion distance of the second terminal between the (i-1) th sampling moment and the ith sampling moment is represented, and r represents the mean value of the motion distances of the second terminal between every two adjacent sampling moments in the K sampling moments.
In a specific implementation process, the movement distance of the second terminal between two adjacent sampling moments can be calculated through the position information acquired by the second terminal at each sampling moment, and then the movement distance mean value is calculated according to a plurality of movement distances, so that the position change standard deviation can be calculated.
For example, if the sampling time is K, and the position information acquired by the corresponding second terminal is also K, the second terminal calculates that the movement distance between two adjacent sampling times is K-1. The calculated K-1 motion distances are added and divided by (K-1), and then the motion distance mean value can be obtained.
After the position change standard deviation σ of the second terminal is calculated, the position change standard deviation of the second terminal is normalized, so that the position weight w of the second terminal is obtained.
And a substep S1022 of calculating a sharing weight of the second terminal according to the location weight of the second terminal based on a sharing weight formula.
The smaller the value of the position standard deviation is, the smaller the fluctuation of the position information acquired by the second terminal in the K sampling moments is, the greater the sharing reliability of the position information is, that is, the greater the sharing weight of the position information is. Therefore, a sharing weight formula may be employed to calculate the sharing weight of the second terminal according to the location weight of the second terminal.
In a specific implementation process, the sharing weight formula may be:
wherein, ω isjRepresenting the sharing weight, w, of the second terminal jjIndicating the location weight of the second terminal j and N the total number of second terminals.
And step S103, transmitting the position information and the sharing weight of the second terminal to the first terminal, and enabling the first terminal to calculate the position information of the first terminal based on the position information and the sharing weight of the second terminal.
The position information of the second terminal and the sharing weight are transmitted to the first terminal together, so that the first terminal can calculate the position information of itself based on the acquired information, and the calculated position information is used as the position information at the time of the position missing.
In a specific implementation, the first terminal may calculate its location information based on the following formula.
Wherein x isT0Position information in x-direction, x, indicating absence of the first terminalT0Position information, ω, indicating the y-direction in which the first terminal is missingjRepresenting the sharing weight, x, of the second terminal jjIndicating the position information of the second terminal j in the x-direction, yjIndicating the position information of the second terminal j in the y direction, N indicating the second terminalThe total number of the cells.
In the position location method provided in the foregoing embodiment, the position request information sent by the first terminal is received, the position information of the second terminal is obtained based on the position request information, the sharing weight of the second terminal is calculated according to the position information of the second terminal, and finally the position information and the sharing weight of the second terminal are sent to the first terminal again, so that the first terminal calculates the position information of the first terminal based on the position information and the sharing weight of the second terminal, thereby implementing position location of the first terminal. The first terminal is a terminal which fails to collect the position information, and the second terminal is a terminal which can normally collect the position information. Through multi-terminal joint positioning, when the first terminal loses the positioning capability, the missing position information of the first terminal can be supplemented according to the position information of the second terminal, so that the first terminal can obtain the missing position information, and the accuracy of the obtained position information is improved.
Referring to fig. 3, fig. 3 is a schematic flow chart of another position location method according to an embodiment of the present invention.
As shown in fig. 3, the position locating method includes steps S201 to 204.
Step S201, a plurality of terminals are pre-configured, so that the terminals are in the same ad hoc network.
The method comprises the steps of pre-configuring a plurality of terminals for collecting position information and constructing an ad hoc network, so that the plurality of terminals are in the same ad hoc network, and position information sharing among the plurality of terminals is facilitated.
In the specific implementation process, each terminal in the ad hoc network respectively creates and maintains a position information summary table of itself. The location information summary table includes the MAC address of the terminal, the IP address allocated by the ad hoc network to the terminal, the time of acquiring the location information, the location information acquired at each acquisition time, the number of ad hoc network members, the start time of the positioning failure, and the like.
In one embodiment, the position location method includes: and receiving a joining request message sent by the terminal to be joined, and sending a joining response message to the terminal to be joined based on the joining request message, so that the terminal to be joined joins the ad hoc network based on the joining response message.
When a terminal to be added needs to be added into the ad hoc network, the terminal to be added sends a join request message to the terminal in the ad hoc network to apply for joining the ad hoc network. And after receiving the joining request message sent by the terminal to be joined, the terminal in the ad hoc network sends a joining response message to the terminal to be joined.
If the terminal to be added receives the addition response message, the terminal to be added can be added into the ad hoc network based on the addition response message, the successful addition message is broadcasted to other terminals in the ad hoc network, and meanwhile, a position information summary table of the terminal to be added is created and used for storing the contents such as position information and the like collected after the terminal to be added is added into the ad hoc network; and if the terminal to be joined does not receive the joining response message, the joining request message is retransmitted.
In the specific implementation process, as there may be a plurality of terminals in the ad hoc network, the terminal to be added may join the ad hoc network after receiving the join response message sent by at least one terminal in the ad hoc network.
In addition, when the terminal in the ad hoc network sends the join response message to the terminal to be joined, the join response message needs to be sent before the timer is cut off, that is, the join response message needs to be sent within the preset response time. If the preset response time is exceeded, the join response message may be considered as an invalid message.
In one embodiment, the position location method further comprises: and receiving IP information sent by the terminal to be added, maintaining the member information of the ad hoc network according to the IP information, and sending an IP receiving message to the terminal to be added based on the IP information.
After the terminal to be added joins the ad hoc network, the terminal to be added sends IP information to other terminals in the ad hoc network, wherein the IP information refers to an IP address distributed by the ad hoc network for the terminal to be added. After receiving the IP information, other terminals in the ad hoc network update their own location information summary table, that is, update the number of ad hoc network members in the location information summary table.
After receiving the IP information, other terminals in the ad hoc network send IP receiving information to the terminal to be added, which indicates that the IP information is received.
Step S202, receiving a position request message sent by the first terminal in the ad hoc network, and acquiring the position information of the second terminal based on the position request message.
The first terminal is a terminal which fails to collect the position information, and the second terminal is a terminal which can normally collect the position information. Therefore, it can be understood that when a terminal in the ad hoc network fails to acquire location information at a certain time, the terminal is referred to as a first terminal, and the rest terminals in the ad hoc network that can normally acquire location information are referred to as second terminals.
After failing to acquire the position information, the first terminal sends a position request message to a second terminal in the ad hoc network so as to acquire the position information of the second terminal based on the position request message.
Step S203, calculating the sharing weight of the second terminal according to the position information of the second terminal.
After the position information of the second terminal is acquired, the sharing weight of the second terminal may be calculated according to the position information of the second terminal. The sharing weight refers to a capability weight of the second terminal contributing its own location information to the first terminal.
In a specific implementation process, the position change standard deviation of the second terminal may be calculated according to the position information of the second terminal, and then the position change standard deviation of the second terminal is normalized to obtain the sharing weight of the second terminal.
When the number of the second terminals is multiple, the sharing weight of each second terminal is calculated respectively so as to calculate the position information of the first terminal.
And step S204, transmitting the position information and the sharing weight of the second terminal to the first terminal, and enabling the first terminal to calculate the position information of the first terminal based on the position information and the sharing weight of the second terminal.
And sending the position information of the second terminal and the sharing weight to the first terminal together, so that the first terminal can calculate the position information of the first terminal based on the acquired position information of the second terminal and the sharing weight, and using the calculated position information as the position information of the first terminal at the time of position missing.
In the position location method provided in the foregoing embodiment, an ad hoc network is formed by a plurality of terminals, then the position request information sent by a first terminal in the ad hoc network is received, the position information of a second terminal is obtained based on the position request information, then the sharing weight of the second terminal is calculated according to the position information of the second terminal, and finally the position information and the sharing weight of the second terminal are retransmitted to the first terminal, so that the first terminal calculates the position information of the first terminal based on the position information and the sharing weight of the second terminal, and the position location of the first terminal is realized. The first terminal is a terminal which fails to acquire the position information, and the second terminal is a terminal which can normally acquire the position information. Through multi-terminal joint positioning, when the first terminal loses the positioning capability, the missing position information of the first terminal can be supplemented according to the position information of the second terminal, so that the first terminal can obtain the missing position information, and the accuracy of the obtained position information is improved.
