Currently, most of positioning functions of tracking wearable electronic devices (Tracker products) are realized by a positioning module (generally acquiring Tracker geographic position coordinates through fusion positioning) and a data communication module (uploading position information to a cloud server through a wireless network). Once the positioning function related module is abnormal, the product cannot work normally. Moreover, tracker type products have higher requirements on power consumption, and when in real-time positioning, the positioning function must keep a working state, so that the power consumption and the cruising ability of the products are extremely high.
In view of the foregoing, an embodiment of the present application provides a positioning system, as shown in fig. 1, including: the system comprises a cloud server 2, a wearable electronic device 1 in communication connection with the cloud server 2 and an auxiliary positioning device 3. Wherein, the wearable electronic device 1 and the auxiliary positioning device 3 are both internally provided with a short-distance wireless communication module, for example: bluetooth module, wireless WIFI module, zigBee module, etc.).
The wearable electronic equipment 1 and the auxiliary positioning equipment 3 are communicated with the cloud server 2 through the wireless communication module, so that the wearable electronic equipment 1 and the auxiliary positioning equipment 3 can receive instructions of the cloud server 2 and send relevant information of the wearable electronic equipment 1 and the auxiliary positioning equipment 3 to the cloud server 2, and the wearable electronic equipment 1 and the auxiliary positioning equipment 3 can communicate with each other through the short-distance wireless communication module.
The auxiliary positioning device 3 may be a tracking wearable device, i.e. a Tracker device or other accessible internet device with a short-range communication module, and may be specifically classified into three types: fixed location auxiliary equipment (hereinafter FLT, placed in a fixed location, such as a building, pole, etc.), if the equipment is a Tracker, a positioning module is not required, and the equipment can also be other communication equipment (such as a wireless router); if the fixed route auxiliary equipment (hereinafter referred to as RRT) is a Tracker, the fixed route auxiliary equipment (hereinafter referred to as RRT) is placed on a fixed route vehicle, such as a bus, a subway, a high-speed rail and the like, and the fixed route auxiliary equipment does not need a positioning module, and can be other communication equipment (such as an Internet of vehicles equipment); a free route aid (hereinafter FRT) placed on other vehicles, which may be a Tracker or other communication device (e.g., a car networking device). All the auxiliary positioning devices 3AT are powered by an external power supply.
The function of each device in the positioning system of this embodiment is as follows.
The wearable electronic device 1 sends an auxiliary positioning request to the cloud server 2, wherein the auxiliary positioning request comprises the position information of the wearable electronic device 1. There may be various conditions for transmitting a request, a user manually transmitting a request, automatically transmitting a request according to the power value of the wearable electronic device 1, and the like. For example: when the positioning module of the wearable electronic device 1 is damaged or the electric quantity of the wearable electronic device 1 is insufficient, the wearable electronic device 1 can be automatically triggered to send an auxiliary positioning request.
The cloud server 2 responds to the auxiliary positioning request, searches the auxiliary positioning device 3 within a preset range according to the position information of the wearable electronic device 1, and if the auxiliary positioning device 3 is found, sends an auxiliary positioning mode entering instruction to the wearable electronic device 1 and sends an auxiliary positioning device 1 entering instruction to the auxiliary positioning device 3 within the preset range.
In response to entering the assisted positioning mode instruction, the wearable electronic device 1 turns off the positioning module and turns on the short-range wireless communication module. The wearable electronic equipment 1 is provided with an auxiliary positioning mode in advance, and the positioning module of the wearable electronic equipment 1 is closed and the short-distance wireless communication module is opened during the auxiliary positioning mode.
The wearable electronic device 1 entry instruction includes device information, such as a device ID, of the wearable electronic device 1. The auxiliary positioning device 3 responds to the entering instruction, stores the device information of the wearable electronic device 1 in a supporting device list, starts a short-distance wireless communication module, searches the device information of the nearby wearable electronic device 1, matches the device information in the supporting device list, generates auxiliary positioning information according to the self-position information and the device information of the wearable electronic device 1 if the matched wearable electronic device 1 exists, and sends the auxiliary positioning information to the cloud server 2.
Specifically, when the auxiliary positioning device 3 receives an entry instruction of the wearable electronic device 1, the entry instruction is parsed to acquire device information of the wearable electronic device 1, and the device information of the wearable electronic device 1 is stored in a supporting device list of the auxiliary positioning device 3 in response to the entry instruction, because 1 or more wearable electronic devices 1 needing auxiliary positioning may exist in the vicinity of 1 auxiliary positioning device 3, 1 auxiliary positioning device 3 may support 1 or more wearable electronic devices 1 needing auxiliary positioning, and therefore, the supporting device list may include device information of 1 or more wearable electronic devices 1.
The auxiliary positioning device 3 also starts a short-distance wireless communication module of the auxiliary positioning device 3 in response to the entering instruction, searches device information of nearby wearable electronic devices 1 by using the short-distance wireless communication module, matches the searched device information of the wearable electronic devices 1 with the device information of the wearable electronic devices 1 in the supporting device list, and if the matching is successful, indicates that the wearable electronic devices 1 in the supporting device list are nearby the auxiliary positioning device 3, and at the moment, the position information of the wearable electronic devices 1 nearby the auxiliary positioning device 3 can be determined according to the position information of the auxiliary positioning device 3. Assuming that the device information of the successfully matched wearable electronic device 1 includes a plurality of pieces, at this time, the auxiliary positioning device 3 generates auxiliary positioning information according to its own position information and the device information of the nearby wearable electronic devices 1, and the device information of each wearable electronic device 1 corresponds to a set of auxiliary positioning information, and the auxiliary positioning information is used for determining the position information of the wearable electronic device 1 nearby the auxiliary positioning device 3. The auxiliary positioning device 3 sends the generated 1 or more groups of auxiliary positioning information to the cloud server 2.
Wherein the position information of the auxiliary positioning device 3 is acquired in different ways for different types of auxiliary positioning devices. If the auxiliary positioning device 3 is a fixed position auxiliary device FLT, the position information is a fixed value because of being placed at a fixed position, so that a positioning module is not needed, and when auxiliary positioning is needed, the auxiliary positioning device 3 sends its fixed position to the cloud server 2 every time. If the auxiliary positioning device 3 is a fixed route auxiliary device RRT, since the moving route is fixed and the mileage number and the position information corresponding to the mileage number are fixed each time the fixed route is moved, the position information can be corresponding only according to the mileage number. The detailed method for acquiring the position of the RRT is as follows: because the RRT is a fixed line, each mileage on the fixed line can correspond to a determined position coordinate, a corresponding table of the mileage and the position is stored in the RRT, and the calculated mileage of the position is cleared before the fixed line is moved each time, so that the corresponding position can be found according to the mileage. If the auxiliary positioning device 3 is a free route auxiliary device FRT the function of the wearable electronic device 1 is substantially the same. According to the characteristics of the auxiliary positioning devices 3 of different types, the auxiliary positioning devices 3 are utilized to position the normally used Tracker and report the position information, so that the power consumption of the normally used Tracker can be effectively reduced, the cruising ability of a Tracker product is improved, and the normal positioning of the Tracker device can be ensured when the positioning module and the network module cannot work; and the external power supply of the auxiliary positioning device 3 does not need to consider the power consumption problem.
The cloud server 2 determines the position information of the wearable electronic device 1 successfully matched with the auxiliary positioning device 3 according to the auxiliary positioning information. The cloud server 2 analyzes the auxiliary positioning information after receiving the auxiliary positioning information to obtain the position information of the auxiliary positioning device 3 and the device information of the wearable electronic device 1, and determines the device information of the wearable electronic device 1 according to the position information of the auxiliary positioning device 3.
Optionally, the auxiliary positioning information further includes a short-range signal strength of the auxiliary positioning device 3, and if the cloud server 2 receives multiple auxiliary positioning information related to the same wearable electronic device 1. Because the closer the auxiliary positioning device 3 is to the wearable electronic device 1, the stronger the short-distance signal strength of the auxiliary positioning device 3 is, the position information of the auxiliary positioning device 3 with the strongest short-distance signal strength in the plurality of auxiliary positioning information can be selected, and the position information of the wearable electronic device 1 is determined by the position information of the auxiliary positioning device 3 with the strongest short-distance signal strength, so that the accuracy of the position information of the wearable electronic device 1 is further ensured.
In this embodiment, when receiving an auxiliary positioning mode entering instruction sent by the cloud server 2, the wearable electronic device 1 closes the positioning module and opens the short-distance wireless communication module in response to the auxiliary positioning mode entering instruction, and the cloud server 2 determines the position information of the wearable electronic device 1 according to the auxiliary positioning information sent by the auxiliary positioning device 3. In this way, even if the positioning module of the wearable electronic device 1, i.e. the Tracker type device, is abnormal, the positioning function can be realized by means of the auxiliary positioning device 3; and because the positioning module does not need to be started when the positioning function is realized by the aid of the auxiliary positioning equipment 3, the power consumption is low.
In some examples, the cloud server 2 is further configured to send an instruction to exit from the auxiliary positioning mode to the wearable electronic device 1 if the auxiliary positioning device 3 within the preset range is not found, and the wearable electronic device 1 starts the positioning module in response to the exit instruction. That is, if the cloud server 2 does not find the auxiliary positioning device 3 within the preset range of the position of the wearable electronic device 1, it indicates that there is no auxiliary positioning device 3 near the wearable electronic device 1, and the position information of the wearable electronic device 1 cannot be determined by means of the auxiliary positioning device 3, at this time, the cloud server 2 sends an instruction for exiting the auxiliary positioning mode to the wearable electronic device 1, and the wearable electronic device 1 starts the positioning module and closes the short-distance wireless communication module in response to the exiting instruction.
In some examples, the auxiliary positioning device 3 is further configured to delete the device information of the wearable electronic device 1 that is not searched from the support device list if the device information of the wearable electronic device 1 in the support device list is not searched within a preset time period or a preset number of times; if the list of support devices is emptied, the short-range wireless communication module is turned off.
In this embodiment, the device information of the wearable electronic device 1 that is not searched in the preset time period or the preset times in the supporting device list is deleted, so that the problem that the auxiliary positioning device 3 consumes a long time when the device information of the wearable electronic device 1 is matched due to excessive device information of the wearable electronic device 1 that is not available in the supporting device list is avoided. If the list of supporting devices is emptied, the Bluetooth module is turned off, and the power consumption of the auxiliary positioning device 3 is reduced.
In the following, a bluetooth BLE module is described with reference to fig. 2, where NT refers to the wearable electronic device 1, cs refers to the cloud server 2, and at refers to the auxiliary positioning device 3.
NT sends a request to the CS to enter an assisted positioning mode (there may be various transmission request conditions, such as a user manually transmitting a request, automatically transmitting a request according to an electric quantity value, etc.); the CS searches the AT in the effective radius according to the geographical position reported by the NT, if the AT is found, the CS sends an instruction for entering the auxiliary positioning mode to the NT, and simultaneously sends an NT entering instruction containing NT equipment information to all the found AT; and after receiving the instruction, the NT closes the positioning and data communication module and enters a BLE Slave mode to start BLE long broadcast, and after receiving the instruction, the AT adds the equipment information of the NT into the own NT equipment list and starts a BLE Master mode to search the long broadcast of the equipment in the auxiliary equipment list.
If ATi (ith AT) searches BLE devices in its own NT device list, ATi assembles the NT device information, its own location information, and BLE signal strength into a message, and sends the message to CS; after receiving the position information message sent by ATi, the CS takes the position information of ATi as the position information of NT, if the CS receives multiple position reports of the same NT AT the same time, the CS selects the position information with the highest BLE signal strength as the position of NT, and AT in the effective radius of ATi is searched again, if so, the CS sends NT entry instructions containing NT equipment information to all the searched ATs.
If the CS does not inquire about available AT, sending a message to the NT to exit the auxiliary positioning mode; if the AT does not search for a certain NT in the NT equipment list within the preset search time or times, deleting the NT from the NT equipment list; if the AT's NT device list is cleared, the AT turns off Bluetooth.
The positioning system in the embodiment can be applied to the application scene commonly used by the tracking equipment at present, the main application environment is an urban traffic environment, and the positioning system can have a better improvement effect on the real-time positioning function in the urban traffic environment of the tracking equipment. The Tracker products expand the positioning mode and improve the robustness and usability of related products.
The embodiment of the application provides an auxiliary positioning method which is applied to wearable electronic equipment comprising a short-distance wireless communication module. The flowchart of the assisted positioning method in the present application is shown in fig. 3, and includes:

Specifically, the present embodiment may have various transmission request conditions, in which a user manually transmits a request, automatically transmits a request according to a power value of the wearable electronic device, and the like. For example: when the positioning module of the wearable electronic device is damaged or the electric quantity of the wearable electronic device is insufficient, the wearable electronic device can be automatically triggered to send an auxiliary positioning request.
The auxiliary positioning request comprises the position information of the wearable electronic device, and the cloud server responds to the auxiliary positioning request and searches the auxiliary positioning device in a preset range according to the position information of the wearable electronic device.
Step S12: and judging whether an auxiliary positioning mode entering instruction sent by the cloud server is received or not.
Step S13: and responding to the instruction of entering the auxiliary positioning mode, closing the positioning module, starting the short-distance wireless communication module, and determining the position information of the wearable electronic equipment according to the auxiliary positioning equipment by the cloud server.
Specifically, the wearable electronic device is provided with an auxiliary positioning mode in advance, and the positioning module of the wearable electronic device is closed and the short-distance wireless communication module is opened in the auxiliary positioning mode. If the cloud server finds auxiliary positioning equipment within a preset range of the position of the wearable electronic equipment, the cloud server sends an instruction for entering an auxiliary positioning mode to the wearable electronic equipment. When the wearable electronic equipment responds to an auxiliary positioning mode entering instruction and enters an auxiliary positioning mode, the cloud server determines the position information of the wearable electronic equipment according to the auxiliary positioning equipment within a preset range of the cloud server, so that even if the positioning module of the wearable electronic equipment, namely the Tracker equipment is abnormal, the positioning function can be realized by means of the auxiliary positioning equipment; and because the positioning module does not need to be started when the positioning function is realized by the aid of the auxiliary positioning equipment, the power consumption is low.
Step S14: and receiving an instruction for exiting the auxiliary positioning mode sent by the cloud server, and starting the positioning module by the wearable electronic equipment in response to the exiting instruction.
Specifically, if the cloud server does not find the auxiliary positioning device within the preset range of the position of the wearable electronic device, it is indicated that the auxiliary positioning device is not near the wearable electronic device, and the position information of the wearable electronic device cannot be determined by means of the auxiliary positioning device, at this time, the cloud server sends an instruction for exiting the auxiliary positioning mode to the wearable electronic device, and the wearable electronic device starts the positioning module and closes the short-distance wireless communication module in response to the exiting instruction.
In the following description, with reference to fig. 2, the short-range wireless communication module is a bluetooth BLE module, NT refers to a wearable electronic device, CS refers to a cloud server, and AT refers to an auxiliary positioning device.
And the CS searches the AT in the effective radius according to the position information reported by the NT, if the AT is found, the CS sends an instruction for entering the auxiliary positioning mode to the NT, and simultaneously sends NT entering instructions containing NT equipment information to all the found AT. If the NT does not receive the instruction of entering the auxiliary positioning mode issued by the CS or receives the instruction of failing to enter the auxiliary positioning mode issued by the CS, the NT keeps a normal state; if NT receives the instruction of entering the auxiliary positioning mode issued by CS, the positioning module is closed, NT opens the BLE Slave mode and triggers BLE long broadcast, and NT enters the auxiliary positioning mode. At this time, the cloud server determines the position information of the wearable electronic device according to the auxiliary positioning device.
The embodiment of the application provides an auxiliary positioning method which is applied to a cloud server. The flowchart of the assisted positioning method in the present application is shown in fig. 4, and includes:
step S21: an assisted location request is received from the wearable electronic device, the assisted location request including location information of the wearable electronic device.
