The embodiment provides a cart positioning method, wherein the method is applied to a communication positioning system, the communication positioning system is installed on a cart, and the communication positioning system comprises a first positioning module and a second positioning module.
Referring to a flowchart of a method for positioning a cart shown in fig. 1, the method specifically includes the following steps:
step S102, positioning a target cart by using a first positioning module to obtain position information corresponding to the target cart;
The above location information can be understood as a specific location of the target cart in the world map.
Step S104, judging whether a connection request sent by a user terminal is received;
The user terminal may be understood as a device having a networking function, such as a smart phone or a tablet computer, used by a user, and typically, an application program corresponding to the communication positioning system is pre-installed on the user terminal, and the user may send a connection request to the communication positioning system through the application program.
If a connection request sent by a user terminal is received, the user is indicated to want to connect with a communication positioning system on the target cart through the user terminal, and then the positioning of the target cart can be performed by executing the step S106; if the connection request sent by the user terminal is not received, it indicates that the user does not currently want to connect to the communication positioning system on the target cart through the user terminal, and the current positioning of the target cart can be obtained by executing step S108.
Step S106, positioning the target cart by using a second positioning module;
Step S108, the position information of the target cart obtained by the first positioning module is sent to the user terminal.
When the user is not connected with the communication positioning system and needs to acquire the current position of the target cart, the position information of the target cart acquired by the first positioning module can be sent to the user terminal for display, so that the user can quickly position the target cart according to the position information.
The embodiment of the application provides a method for positioning a cart, wherein the method is applied to a communication positioning system, the communication positioning system is arranged on the cart, and the communication positioning system comprises a first positioning module and a second positioning module; positioning the target cart by using a first positioning module to obtain position information corresponding to the target cart; when judging that the connection request sent by the user terminal is received, positioning the target cart by using a second positioning module; if the connection request sent by the user terminal is not received, the position information of the target cart obtained by the first positioning module is sent to the user terminal; according to the application, the target cart can be positioned through the two positioning modules, so that the problem that the target cart cannot be positioned due to poor signals of the single positioning module can be effectively avoided, and the use experience of a user is improved.
The embodiment provides another cart positioning method, which is realized on the basis of the embodiment; this embodiment focuses on a specific implementation of positioning a target cart using a first positioning module or a second positioning module. As shown in fig. 2, the method for positioning a cart in this embodiment includes the following steps:
Step S202, positioning information of each positioning device on a target cart is respectively obtained;
In this embodiment, the first positioning module includes a plurality of positioning devices, where the number of the plurality of positioning devices is at least 2, for example, the first positioning module includes but is not limited to four positioning devices including a beidou system, a GPS (Global Positioning System, a global positioning system), a GLONASS (GLOBAL NAVIGATION SATELLITE SYSTEM, a global satellite navigation system), and a Galileo (Galileo satellite navigation system), where the positioning devices included in the first positioning module may be set according to actual needs, and are not limited herein.
The positioning information is the position information obtained by positioning the target cart through the positioning device. Continuing the previous example, the positioning information of each positioning device on the target cart can be obtained by using the four positioning devices.
Step S204, carrying out weighted average calculation on a plurality of positioning information to obtain the position information of the target cart;
According to the embodiment, the positioning information of the plurality of positioning devices is subjected to weighted average calculation, the positioning result of the weighted average calculation of the positioning devices is determined to be the final position information of the target cart, and the plurality of positioning devices can cooperatively work to realize seamless positioning service coverage in a large range, so that the positioning precision is improved.
Step S206, judging whether a connection request sent by a user terminal is received;
If yes, step S208 is performed, and if no, step S210 is performed.
Step S208, positioning the target cart based on the second positioning module and the user terminal;
When the second positioning module is a Bluetooth positioning device, the positioning of the target cart is realized according to the Bluetooth positioning device and the user terminal, and the specific realization process is as follows: and sending a broadcast signal to the user terminal through the Bluetooth positioning device so as to trigger the user terminal to extract an RSSI (received signal strength Indication) value carried by the broadcast signal, and calculating the position distance between the user terminal and the target cart based on the RSSI value.
The positioning mode based on the bluetooth positioning device and the user terminal is the same as the existing bluetooth positioning mode, so detailed description is omitted here.
Besides the bluetooth positioning mode, the second positioning module in this embodiment may be an ultra-wideband positioning device, and the accurate positioning is achieved by using an ultra-wideband positioning technology, and the positioning process of the target cart according to the ultra-wideband positioning device and the user terminal is as follows: and sending positioning feedback information corresponding to the received positioning query information to the user terminal through the ultra-wideband positioning device so as to trigger the user terminal to calculate the position distance between the user terminal and the target cart based on the sending time of the sent positioning query information and the receiving time of the received positioning feedback information, and trigger the user terminal to determine the position of the target cart relative to the user terminal based on the positioning feedback information.
In general, the above-described position distance can be expressed by the following formula:
d= (t 2-t 1)/2; wherein D represents the distance between the user terminal and the target cart, t2 represents the receiving time of the user terminal receiving the positioning feedback information, and t1 represents the sending time of the user terminal sending the positioning query information.
In this embodiment, the distance between the current user terminal and the target cart may be calculated based on the sending and receiving time of the information, and the user terminal may also calculate the azimuth of the target cart relative to the user terminal through the positioning feedback information, and may accurately determine the position of the target cart relative to the user through the ultra wideband positioning device and the user terminal; because the positioning method based on the ultra wideband in this embodiment is the same as the existing positioning method using the ultra wideband, detailed description thereof will not be given here.
Furthermore, in order to increase the accuracy of positioning, the positioning of the target cart based on the Bluetooth positioning device and the user terminal can be weighted and averaged with the positioning of the target cart based on the ultra-wideband positioning device and the user terminal, so as to obtain the position of the final target cart.
In order to facilitate the user to know the specific position of the current target cart, in actual use, the position information of the target cart obtained by the second positioning module can be sent to the user terminal for display, so that the user can quickly find the current target cart.
Step S210, the position information of the target cart obtained by the first positioning module is sent to the user terminal.
Generally, the communication positioning system further comprises a communication module, and the communication positioning system is in communication connection with the cloud platform through the communication module; after the first positioning module is used for positioning the target cart to obtain position information, the position information can be sent to the cloud platform for storage through the communication module.
When the user terminal is not connected to the communication positioning system and is positioned by the second positioning module, in order to enable the user terminal to obtain the position of the target cart as well, in this embodiment, the position information corresponding to the target cart stored to the cloud platform may be sent to the user terminal.
Specifically, the above step S210 may be implemented through steps A1 to A2;
step A1, triggering a user terminal to send an acquisition instruction carrying identification information corresponding to a target cart to a cloud platform;
In general, the cloud platform can be in communication connection with a plurality of communication positioning systems, so that position information corresponding to a plurality of different carts can be stored, in order to facilitate a user to find a target cart, the user can inquire through an application program corresponding to the communication positioning system installed on a user terminal, specifically, after logging in the application program, the user can send an acquisition instruction carrying identification information corresponding to the target cart to the cloud platform by utilizing an inquiry interface of the application program; the identification information is understood to be a unique identification of the cart, and may be represented by numerals, characters, letters, or the like, which are not limited herein.
And step A2, triggering the cloud platform to send the position information of the target cart obtained by the first positioning module to the user terminal for display based on the identification information.
After the cloud platform receives the acquisition instruction, the position information matched with the identification information carried by the acquisition instruction can be searched from the plurality of position information and sent to the user terminal so as to display the position of the current target cart.
In actual use, the position information of the cart stored to the cloud platform also carries the identification information corresponding to the cart, so that the process of searching the position information of the target cart is as follows: first, target identification information matched with identification information carried by an acquisition instruction is searched from a plurality of pieces of identification information stored in a cloud platform, and then position information corresponding to the target identification information is determined as position information of a target cart to be searched by a user.
According to the cart positioning method, when the first signal intensity value is larger than the second signal intensity value, the first positioning module is used for positioning the target cart, and when the first signal intensity value is equal to or smaller than the second signal intensity value, the second positioning module is used for positioning the target cart, so that flexible switching between the first positioning module and the second positioning module can be performed in real time according to the intensity of signals received by the positioning modules, and positioning of the target cart is achieved by the positioning module with better signals.
In practical use, in order to enable the communication positioning system to work normally, the communication positioning system further comprises a power supply module to supply power to the communication positioning system by using the power supply module, wherein the power supply module can be powered by a battery or can be charged by solar energy and USB, and the communication positioning system is not limited herein.
