On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

The terms used herein in the specification of the application are only for the purpose of describing specific embodiments, and are not intended to limit the application.

It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element, or connected to the other element through an intervening element. In addition, "connection" in the following embodiments should be understood as "electrical connection", "communication connection" and the like in the case of the transmission of electrical signals or data between the connected objects.

It should also be understood that the terms "comprising/comprising" or "having" etc. specify the presence of stated features, integers, steps, operations, components, parts or combinations thereof, but do not exclude the presence or addition of one or more The possibility of other features, integers, steps, operations, components, parts or combinations thereof.

In one embodiment, as shown in FIG. 1 , a method for locating an Internet of Things module is provided, and the application of the method to an electronic device with an Internet of Things module is used as an example for illustration, including the following steps:

S102. Detect the strength of the satellite signal, and compare the strength of the satellite signal with a threshold.

S104, when the result of the comparison is that the strength of the satellite signal is less than the threshold, switch the Bluetooth state to the search state, and periodically search for the Bluetooth broadcast message; the Bluetooth broadcast message includes the location information of another IoT module; the Bluetooth broadcast message is another It is output when the strength of the satellite signal detected by the IoT module is greater than the threshold.

S106. When the Bluetooth broadcast message is found, use the location information of another IoT module in the Bluetooth broadcast message as the location information of the main body.

Among them, the Internet of Things module can support the satellite positioning function, which is used to realize the tracking of the position information of the main body. It can be understood that the ontology refers to the Internet of Things module itself, and the location information of the ontology refers to information on the location of the Internet of Things module itself. The IoT module also supports Bluetooth function, which includes Bluetooth broadcast function and Bluetooth search function. The size of the threshold can be set according to the actual situation.

Specifically, the IoT module detects the strength of the satellite signal in real time, and compares the strength of the satellite signal with the threshold. If the result of the comparison is that the strength of the satellite signal is less than the threshold, it indicates that the strength of the detected satellite signal is weak, and the currently detected position information may be inaccurate. Therefore, the IoT module switches the Bluetooth state to the search state, and periodically searches whether there is a Bluetooth broadcast message nearby. The Bluetooth broadcast message is output when the strength of the satellite signal detected by other IoT modules is greater than the threshold. The Bluetooth broadcast message includes location information detected by another IoT module.

When the Internet of Things module searches for a Bluetooth broadcast message output by another Internet of Things module, it uses the location information of another Internet of Things module in the Bluetooth broadcast message as the location information of the main body. It can be understood that the Bluetooth broadcast message is output by another IoT module when the intensity of the detected satellite signal is greater than a threshold. When the satellite positioning system fails or the satellite signal in the area is weak, the IoT module realizes repositioning by sharing the high-precision location information detected by other nearby IoT modules, thereby improving the accuracy of the positioning information of the body . The electronic device with the Internet of Things module can also upload the positioning information of the main body to the server. Even in an area where the satellite signal is weak in the environment where the electronic device is located, the electronic device can upload the high-precision location information of another IoT module searched through the Bluetooth function as the main body location information to the server. The server can monitor the location of the electronic device in real time, and can find the electronic device at any time according to the location information uploaded by the Internet of Things module, which expands the application scenarios of the Internet of Things module.

The application detects the strength of the satellite signal, and switches the Bluetooth state to the search state when the strength of the satellite signal is lower than the threshold, and periodically searches for nearby Bluetooth broadcast messages. When the Bluetooth broadcast message is found, the location information of another IoT module in the Bluetooth broadcast message is used as the location information of the main body. Furthermore, this application can effectively improve the positioning of the body by using the obtained high-precision location information shared by other nearby IoT modules as the location information of the body when the satellite signal in the area where the body is located is weak or the body positioning system fails. precision.

In one of the embodiments, the satellite signal is a GPS (Global Positioning System, Global Positioning System) signal; the data type of the location information is NMEA data; the search mode of the search state is BLE (Bluetooth Low Energy, Bluetooth Low Energy) search; The broadcast mode of broadcast state is BLE broadcast.

Specifically, the IoT module can use a GPS positioning chip, and the detected satellite signal is GPS information. The GPS positioning data may be NMEA data, that is, the data type of the location information is NMEA data. Moreover, the IoT module supports the BLE function, and the power consumption of BLE is low. Adding the BLE function to the IoT module will not increase excessive power consumption. When the Internet of Things module switches the Bluetooth state to the search state, the search mode is the BLE search mode, and the Internet of Things module performs periodic searches. Similarly, when the IoT module switches the Bluetooth status to the broadcast status, the broadcast mode is the BLE broadcast mode, and the IoT module broadcasts periodically.

The BLE broadcast and search functions of this application will not significantly increase the power consumption of the IoT module, and achieve more energy saving and controllable power consumption.

In one of the embodiments, the positioning method of the Internet of Things module may also include: when the result of the comparison is that the satellite signal strength is greater than the threshold, switching the Bluetooth state to the broadcast state, and periodically performing the Bluetooth broadcast message including the current position information Broadcasting; the broadcasting power in the broadcasting state satisfies the power condition; the power condition is for the purpose of reducing the coverage of broadcasting.

Specifically, when the Internet of Things module detects that the strength of the satellite signal is greater than the threshold, it means that the satellite signal in the environment where the Internet of Things module is located is strong and the positioning information is accurate, so the Internet of Things module can switch the Bluetooth state to the broadcast state, which will include detection The Bluetooth broadcast message of the current location information is periodically broadcast, and the detected high-precision location information is shared with other nearby IoT modules. Other IoT modules that detect weak satellite signals in the vicinity can search for the Bluetooth broadcast message, thereby using the location information in the Bluetooth broadcast message as its location information, realizing high-precision location sharing between IoT modules, and effectively The positioning accuracy of each IoT module is improved.

In addition, the broadcast power of the Bluetooth state in the broadcast state can be adjusted to meet the power condition, and the power condition is aimed at reducing the coverage of the broadcast. By reducing the power of the Bluetooth broadcast, the coverage of the Bluetooth broadcast is reduced, so that the distance between the IoT module and other IoT modules that have searched for the Bluetooth broadcast message is reduced, that is, the high precision detected by the IoT module is reduced. The actual position error between the location and other IoT modules that have searched for the Bluetooth broadcast message, so that other IoT modules that receive the Bluetooth broadcast message that includes the high-precision location information use the location information in the Bluetooth broadcast message as When using its location information, the location shared through Bluetooth location is closer to its actual location, thereby improving the location accuracy.

This application compares the strength of the detected satellite signal with the size relationship between the threshold, selectively switches the Bluetooth state to the search state or the broadcast state according to the comparison result, and periodically searches for the information output by another Internet of Things module that includes another Internet of Things module. The Bluetooth broadcast message of the location information, or the periodic broadcast including the Bluetooth broadcast message of the detected current location information, enables the sharing of high-precision location information among the IoT modules. When the GPS positioning chip of the IoT module fails or the positioning signal of the current environment is weak, the high-precision positioning information of other nearby IoT modules can be obtained as the ontology positioning information, which effectively improves the position accuracy. Moreover, the broadcast power of the IoT module of the present application satisfies the power condition aimed at reducing the broadcast coverage, which can further improve the location accuracy of the IoT module that uses the location information in the received Bluetooth broadcast message as its own location information.

In one of the embodiments, as shown in Figure 2, the IoT module positioning method may also include the following steps:

S202. Confirm the area where the main body is located.

S204. Adjust the search period of the search state according to the usage intensity of the Internet of Things modules in the area where the Ontology is located.

Specifically, when the GPS positioning chip of the Internet of Things module fails or the signal strength of the GPS satellite at the location is weak, in the case of switching the Bluetooth state to the search state and periodically searching for nearby Bluetooth broadcast messages, the Internet of Things module can Adjust the search cycle according to the intensive use of IoT modules in the area where Ontology is located. Due to the mobility of devices equipped with IoT modules, in areas where IoT modules are used intensively, devices come and go frequently, that is, devices with IoT modules enter and leave the area more frequently, and the IoT modules search for each other's BLE The probability of broadcasting is relatively high. Therefore, when the Bluetooth state is switched to the search state, the IoT module can increase the search cycle. Similarly, when the IoT modules in the area where the Ontology is located are less intensively used, the probability of finding each other’s BLE broadcasts between IoT modules is relatively low due to the small number of devices in the area. Therefore, the Bluetooth search cycle can be set to reduce.

That is, by confirming the area where the IoT module body is located, the search cycle of the search state is adjusted according to the intensive use of the IoT module in the area. When it is confirmed that the IoT modules in the area where Ontology is located are highly intensively used, increase the search cycle. When it is confirmed that the Internet of Things modules in the area where the main body is located are less intensively used, the search cycle is reduced, so that the application can further reduce the power consumption of the Internet of Things modules and achieve the effect of energy saving.

This application reasonably adjusts the Bluetooth search cycle according to the intensive use of the IoT module in the area where the main body is located, so as to further achieve the effects of reduced power consumption, controllable power consumption, and energy saving.

In one of the embodiments, as shown in Figure 3, the IoT module positioning method may also include the following steps:

S302. When the Bluetooth broadcast message is found, determine whether the number of relay broadcasts of the Bluetooth broadcast message reaches a preset number of times; the number of relay broadcasts is the number of times the Bluetooth broadcast message is forwarded by other IoT modules.

S304. If the result of the judgment is that the number of relay broadcasts does not reach the preset number of times, switch the Bluetooth state to the broadcast state, and broadcast Bluetooth broadcast messages periodically.

Wherein, the preset number of times may be set according to actual conditions.

Specifically, the Internet of Things module may also determine whether the number of relay broadcasts of the searched Bluetooth broadcast message reaches a preset number of times when the Bluetooth broadcast message is found. When the judgment result is that the number of relay broadcasts does not reach the preset number, the IoT module can switch the Bluetooth state to the broadcast state, and periodically broadcast the received Bluetooth broadcast messages.

The number of relay broadcasts is the number of times a Bluetooth broadcast message is forwarded by other IoT modules, that is, the number of relay broadcasts is the number of times a certain IoT module receives a Bluetooth broadcast message including the location information of another IoT module. The number of times the message continues to broadcast, and after another IoT module receives it, the other IoT module continues to broadcast the same Bluetooth broadcast message. For example, when the A IoT module detects high-precision location information, it periodically broadcasts a Bluetooth broadcast message including the location information. The B-IoT module receives the Bluetooth broadcast message, and the number of relay broadcasts of the Bluetooth broadcast message received by the B-IoT module is 0. After receiving the Bluetooth broadcast message, the B IoT module uses the location information in the Bluetooth broadcast message as the body location information of the B IoT module, and continues to broadcast the Bluetooth broadcast message. When the C-IoT module searches for the Bluetooth broadcast message broadcast by the B-IoT module, the number of relay broadcasts of the Bluetooth broadcast message found by the C-IoT module is 1. The C Internet of Things module uses the location information in the Bluetooth broadcast message as the body location information of the C Internet of Things module, and continues to broadcast the Bluetooth broadcast message. And when the D IoT module searches for the Bluetooth broadcast message, the number of relay broadcasts of the Bluetooth broadcast message received by the D IoT module is 2, because the Bluetooth broadcast message has been forwarded by the B IoT module and the C IoT module .

However, if the number of relay broadcasts of the Bluetooth broadcast message output by a certain Internet of Things module is large, it means that the Bluetooth broadcast message has been forwarded by more Internet of Things modules. Since each IoT module has a certain broadcast range, in the case of a large number of relay broadcasts of the Bluetooth broadcast message, the IoT module receiving the Bluetooth broadcast message may be different from the IoT module that originally sent the Bluetooth broadcast message. The distance between the networking modules is relatively large. At this time, the location information in the Bluetooth broadcast message and the actual location of the IoT module that received the Bluetooth broadcast message may have a large error. When the location information in the message is used as the location information of the ontology, the location accuracy is low. Therefore, by limiting the number of relay broadcasts, when the number of relay broadcasts of the searched Bluetooth broadcast messages does not reach the preset number of times, switch the Bluetooth state to the broadcast state, and continue to periodically broadcast the Bluetooth broadcast message without affecting the next Receive the Bluetooth broadcast message, and use the location information in the Bluetooth broadcast message as the location accuracy of the IoT module of the main body location information. When the number of relay broadcasts of the searched Bluetooth broadcast message reaches the preset number of times, the Bluetooth state is no longer switched to the broadcast state, and the Bluetooth broadcast message is no longer broadcast, so that all Internet of Things that can receive the Bluetooth broadcast message When the module uses the location information in the Bluetooth broadcast message as the location information of the main body, the error with its actual location will not be too large, which effectively improves the location accuracy.

Based on the above, this application is based on the huge foundation of the current Internet of Things module and a certain degree of mobility, relying on the BLE search and broadcast mechanism, according to the strength of the detected satellite signal, automatically switch the way of Bluetooth search and broadcast status, to realize the Internet of Things The positioning information is shared between networked modules, and the positioning accuracy is not greatly affected. And according to the reasonable setting of BLE broadcast power and the number of relay broadcasts of Bluetooth broadcast messages, the GPS positioning error is reduced to a controllable range in a small range, effectively improving the location accuracy. The application can also flexibly adjust the BLE search state cycle according to the intensive use of the IoT module in the area where the IoT module is located, effectively reducing the power consumption of the module, and achieving the effect of energy saving and power saving.

It should be understood that although the steps in the flow charts involved in the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed sequentially in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders.
