According to the technical scheme, the signal strength of the connection between the Bluetooth terminal and at least two Bluetooth gateways is obtained, and at least two signal strengths are obtained; adjusting the transmitting power of the Bluetooth terminal according to the at least two signal intensities so as to enable the Bluetooth terminal to be connected with a target Bluetooth gateway in the at least two Bluetooth gateways; based on the connection established between the Bluetooth terminal and the target Bluetooth gateway, the measurement parameters of the Bluetooth terminal are reported to the cloud platform through the target Bluetooth gateway, namely, the transmitting power of the Bluetooth terminal is adjusted through the signal intensity of the connection between the Bluetooth terminal and the Bluetooth gateway, so that the Bluetooth terminal is connected with the target Bluetooth gateway.
It should be noted that the bluetooth terminal of the present invention is preferably a bluetooth low power device, but is not limited to a bluetooth low power device.
There are many implementation manners of step S204, and the present invention provides an implementation manner, in an exemplary embodiment, a first power adjustment broadcast is sent to the at least two bluetooth gateways; and receiving response information returned by the at least two Bluetooth gateways responding to the first power adjustment broadcast, wherein the response information carries at least two signal strengths of the connection between the Bluetooth terminal and the Bluetooth gateway, which are detected by the Bluetooth gateway.
Specifically, to adjust the transmission power of the bluetooth terminal according to at least two signal intensities, first, the signal intensities of the connection between the bluetooth terminal and at least two bluetooth gateways need to be obtained, and the method for obtaining the signal intensities of the connection between the bluetooth terminal and at least two bluetooth gateways includes that the bluetooth terminal sends a first power adjustment broadcast, the bluetooth gateway receives the first power adjustment broadcast, responds to the first power adjustment broadcast, and sends response information carrying the signal intensities of the connection between the bluetooth terminal and the bluetooth gateways detected by the bluetooth gateway to the bluetooth terminal, where the bluetooth gateway may include a first bluetooth gateway, a second bluetooth gateway, a third bluetooth gateway, and the like, and the signal intensity in the response information sent by the first bluetooth gateway is the signal intensity of the connection between the first bluetooth terminal and the bluetooth gateway.
After the bluetooth terminal receives the response information carrying the signal strength of the connection between the bluetooth terminal and the bluetooth gateway, which is detected by the bluetooth gateway, in an optional embodiment, when the signal strength carried in the response information is greater than the first threshold, the transmission power of the bluetooth terminal is reduced, so that the bluetooth terminal is connected with a target bluetooth gateway of the at least two bluetooth gateways.
After receiving the response information, the Bluetooth terminal detects the relationship between the signal intensity of the Bluetooth terminal carried by the response information and the signal intensity of the Bluetooth gateway connection and a preset threshold, reduces the transmitting power of the Bluetooth terminal under the condition that the signal intensity carried by the response information is greater than the first threshold, and finally connects the Bluetooth terminal with a target Bluetooth gateway of the at least two Bluetooth gateways.
Specifically, in the process of reducing the transmission power of the bluetooth terminal, the transmission power of the bluetooth terminal is reduced to a first transmission power corresponding to a next level, where a difference between the transmission power of the bluetooth terminal and the first transmission power is smaller than a second threshold; transmitting a second power adjustment broadcast to the at least two Bluetooth gateways based on the first transmit power; receiving response information returned by the at least two Bluetooth gateways responding to the second power adjustment broadcast, wherein the response information carries at least two signal strengths of the Bluetooth terminal and the Bluetooth gateway, which are detected by the Bluetooth gateways; and reducing the first transmission power to a second transmission power corresponding to a next level of the first transmission power under the condition that the signal strength carried in the response information is greater than the first threshold.
That is to say, when the bluetooth terminal detects that the signal strength carried in the response information is greater than the first threshold, the transmission power of the bluetooth terminal is reduced to the first transmission power corresponding to the next level, that is to say, the transmission power of the bluetooth terminal is reduced according to the level, different levels correspond to different transmission powers, after the transmission power of the bluetooth terminal is reduced to the first transmission power corresponding to the next level, the bluetooth terminal continues to send a second power adjustment broadcast to the bluetooth gateway, and after receiving the second power adjustment broadcast, the bluetooth gateway responds to the second power adjustment broadcast and sends the response information carrying the signal strength of the connection between the bluetooth terminal and the bluetooth gateway, which is detected by the bluetooth gateway, to the bluetooth terminal.
It should be noted that, the bluetooth terminal receives the response information carrying the signal strength of the connection between the bluetooth terminal and the bluetooth gateway detected by the bluetooth gateway again, and detects that the signal strength carried in the response information is still greater than the first threshold, the above operations are continuously executed, that is, the transmission power of the bluetooth terminal continues to decrease according to the level, the bluetooth terminal continues to send the third power adjustment broadcast to the bluetooth gateway, and after receiving the third power adjustment broadcast, the bluetooth gateway responds to the third power adjustment broadcast and sends the response information carrying the signal strength of the connection between the bluetooth terminal and the bluetooth gateway detected by the bluetooth gateway to the bluetooth terminal until the signal strength in the response information is less than the preset threshold, so that the bluetooth terminal is connected with only one bluetooth gateway.
In an exemplary embodiment, the transmitting power of the bluetooth terminal is adjusted according to the at least two signal strengths, so that after the bluetooth terminal is connected with a target bluetooth gateway of the at least two bluetooth gateways, a first gateway probe broadcast is sent to the bluetooth gateway according to a preset period; and under the condition that the Bluetooth terminal does not receive a gateway probe response of the Bluetooth gateway to the first gateway probe broadcast in the preset period, increasing the transmission power of the Bluetooth terminal by one level to a third transmission power.
After the transmission power of the Bluetooth terminal is adjusted, the Bluetooth terminal starts Bluetooth gateway exploration at regular time, and sends a first gateway exploration broadcast to the Bluetooth gateway according to a preset period, if the Bluetooth terminal does not receive a gateway exploration response of the Bluetooth gateway to the first gateway exploration broadcast in the preset period, that is, no Bluetooth gateway receives the first gateway exploration broadcast sent by the Bluetooth terminal, that is, no Bluetooth gateway can receive measurement parameters sent by the Bluetooth device at the moment, and then the transmission power of the Bluetooth terminal needs to be increased by one level to a third transmission power, so that the Bluetooth gateway can receive the first gateway exploration broadcast sent by the Bluetooth terminal, and if the Bluetooth terminal receives the gateway exploration response of the Bluetooth gateway to the first gateway exploration broadcast in the preset period, the Bluetooth terminal continues to maintain a second transmission power.
In one exemplary embodiment, after the transmission power of the Bluetooth terminal is increased by one level to a third transmission power, a second gateway probe broadcast is sent to a Bluetooth gateway based on the third transmission power; and under the condition that the Bluetooth terminal does not receive a gateway probe response of the Bluetooth gateway to the second gateway probe broadcast in the preset period, adjusting the third transmitting power of the Bluetooth terminal to the default power of the Bluetooth terminal.
Specifically, after the transmission power of the bluetooth terminal is increased by one level to a third transmission power, the bluetooth terminal continues to send a second gateway probe broadcast, if the bluetooth terminal receives a gateway probe response of the bluetooth gateway to the second gateway probe broadcast within a preset period, the bluetooth terminal keeps transmitting the third transmission power to the bluetooth gateway, and if the bluetooth terminal does not receive the gateway probe response of the bluetooth gateway to the second gateway probe broadcast within the preset period, the bluetooth terminal adjusts the third transmission power of the bluetooth terminal to a default power of the bluetooth terminal, where the default power may be a factory power, and the embodiment of the present invention does not limit this.
Further, if the bluetooth terminal does not receive a gateway probe response of the bluetooth gateway to the second gateway probe broadcast within the preset period, the transmission power of the bluetooth terminal may be increased by one level to a fourth transmission power again, so that the bluetooth gateway may receive the gateway probe broadcast sent by the bluetooth terminal.
In order to better understand the process of the reporting method of the measurement parameter, the following describes a process of the reporting method of the measurement parameter with reference to an optional embodiment, but is not limited to the technical solution of the embodiment of the present invention.
With the popularization of bluetooth low power (BLE), the internet of things access of various devices adopts a BLE access scheme at present, pure BLE devices are generally devices only using batteries, such as door locks, body fat scales, toothbrushes and the like, and the pure BLE devices generally need to access an internet of things cloud platform through a BLE gateway. BLE gateways are generally plug-in devices, such as BLE sound devices, BLE lamps, and the like. The pure BLE equipment generally establishes an uplink data channel with the BLE gateway in a broadcasting mode, transmits related data, for example, a body fat scale reports measurement parameters such as weight to the BLE gateway, and sends the measurement parameters to the cloud platform through the BLE gateway for recording and storing. The pure BLE device generally establishes an uplink and downlink path with a BLE gateway or a user terminal in a GATT (generic Attribute Profile, abbreviated as generic Attribute configuration file) manner, provides uplink and downlink channel capability for the pure BLE device, and facilitates a cloud or a user to issue an instruction to the BLE device. That is, pure BLE devices operate in a broadcast mode most of the time. The BLE equipment that uses at present all has a plurality of gateways, for example a BLE lock equipment, BLE audio amplifier gateway in sitting room, BLE lamp gateway in bedroom. If the transmitting power of BLE equipment sets up great, BLE audio amplifier gateway and BLE lamp gateway can both receive the message of BLE lock to cloud platform is forwarded to the message that will receive. Therefore, it is necessary to solve the problems in the related art that the transmission Power of the bluetooth terminal is large, multiple gateways can receive the measurement parameters of the bluetooth terminal, and the cloud platform receives the measurement parameters of multiple same bluetooth terminals, and the like.
Fig. 3 is a flowchart of a method for reporting a measurement parameter according to an alternative embodiment of the present invention, which is implemented on the premise that BLE equipment establishes an uplink data channel with a BLE gateway in a broadcast manner, and as shown in fig. 3, the specific steps are as follows:
step S301: a BLE terminal (corresponding to a bluetooth terminal in the above embodiment) receives broadcast information of one or more BLE gateways (corresponding to bluetooth gateways in the above embodiment);
step S302: determining whether to start a power adjustment process according to whether Received Signal Strength Indication (RSSI) in BLE gateway broadcast information reaches a threshold value and whether a BLE terminal adjusts power; starting a power adjustment process under the condition that the signal strength (RSSI) in the BLE gateway broadcast information reaches a threshold value and the BLE terminal does not adjust the power;
it should be noted that, as long as there is a signal strength reaching the threshold and no power adjustment is performed by the BLE terminal, the power adjustment procedure is started according to the signal strength in the BLE gateway broadcast information received by the BLE terminal.
Step S303: the BLE terminal sends power adjustment broadcast;
step S304: after the BLE gateway 1 and the BLE gateway 2 simultaneously receive the power adjustment broadcast sent by the BLE terminal, the BLE gateway 1 and the BLE gateway 2 send power adjustment response broadcast to the BLE terminal and carry the RSSI of the BLE terminal measured by the BLE gateway;
step S305: the BLE terminal determines whether to adjust the power according to the RSSI carried in the response message returned by the gateway, and if the power needs to be adjusted, the first-level power is reduced; if the power does not need to be adjusted, the power adjustment link is exited;
step S306: the BLE terminal transmits the power adjustment broadcast again, i.e. returns to step S303 and loops step S303-step S305;
step S307: if the power is adjusted, the BLE terminal starts the BLE gateway to probe at regular time;
step S308: the BLE terminal sends a gateway probing broadcast;
step S309: if the BLE gateway does not receive the gateway probe response broadcast sent by the BLE gateway, increasing the primary power, returning to the step S308 and circulating the steps S308-S309;
step S310: and if the BLE gateway receives the gateway probe broadcast sent by the BLE terminal, sending a gateway probe response message,
step S311: after the BLE terminal receives the message, the gateway probing process is ended;
step S312: and if the gateway probe response broadcast is not received all the time, restoring the default power and finishing the power adjustment.
It should be noted that, if it can be understood that the gateway probe response broadcast is sent twice without receiving the gateway probe response broadcast all the time, the embodiment of the present invention does not limit this.
Through the steps, the problem that system default power is generally adopted in the aspect of the BLE terminal at present can be solved, and according to the embodiment of the invention, the transmitting power of the BLE equipment is adjusted according to the signal strength of connection between the BLE terminal and the BLE gateway, so that the power consumption is further reduced, and the service life of a battery is prolonged. Through adjusting the transmitting power of the BLE terminal, the far BLE gateway with poor signals receives the signals of the BLE terminal, the number of gateways reporting parameters to the cloud platform is reduced, and the pressure of a data deduplication algorithm of the cloud platform is relieved.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention or portions thereof contributing to the prior art may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (which may be a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.

Specifically, to adjust the transmission power of the bluetooth terminal according to at least two signal intensities, first, the signal intensities of the connection between the bluetooth terminal and at least two bluetooth gateways need to be obtained, and the method for obtaining the signal intensities of the connection between the bluetooth terminal and at least two bluetooth gateways is that the bluetooth terminal sends a first power adjustment broadcast, the bluetooth gateway receives the first power adjustment broadcast, responds to the first power adjustment broadcast, and sends response information carrying the signal intensities of the connection between the bluetooth terminal and the bluetooth gateways detected by the bluetooth gateway to the bluetooth terminal, where the bluetooth gateway may include a first bluetooth gateway, a second bluetooth gateway, a third bluetooth gateway, and the like, and the signal intensity in the response information sent by the first bluetooth gateway is the signal intensity of the connection between the first bluetooth terminal and the bluetooth gateway.
After the bluetooth terminal receives the response information carrying the signal strength of the connection between the bluetooth terminal and the bluetooth gateway, which is detected by the bluetooth gateway, in an optional embodiment, the adjusting module is further configured to reduce the transmission power of the bluetooth terminal when the signal strength carried in the response information is greater than the first threshold, so that the bluetooth terminal is connected to a target bluetooth gateway of the at least two bluetooth gateways.
After receiving the response information, the Bluetooth terminal detects the relationship between the signal intensity of the Bluetooth terminal carried by the response information and the signal intensity of the Bluetooth gateway connection and a preset threshold, reduces the transmitting power of the Bluetooth terminal under the condition that the signal intensity carried by the response information is greater than the first threshold, and finally connects the Bluetooth terminal with a target Bluetooth gateway of the at least two Bluetooth gateways.
Specifically, the adjusting module is further configured to reduce the transmission power of the bluetooth terminal to a first transmission power corresponding to a next level in a process of reducing the transmission power of the bluetooth terminal, where a difference between the transmission power of the bluetooth terminal and the first transmission power is smaller than a second threshold; transmitting a second power adjustment broadcast to the at least two Bluetooth gateways based on the first transmit power; receiving response information returned by the at least two Bluetooth gateways responding to the second power adjustment broadcast, wherein the response information carries at least two signal strengths of the Bluetooth terminal and the Bluetooth gateway, which are detected by the Bluetooth gateways; and reducing the first transmission power to a second transmission power corresponding to a next level of the first transmission power under the condition that the signal strength carried in the response information is greater than the first threshold.
That is to say, when the bluetooth terminal detects that the signal strength carried in the response information is greater than the first threshold, the transmission power of the bluetooth terminal is reduced to the first transmission power corresponding to the next level, that is to say, the transmission power of the bluetooth terminal is reduced according to the level, different levels correspond to different transmission powers, after the transmission power of the bluetooth terminal is reduced to the first transmission power corresponding to the next level, the bluetooth terminal continues to send a second power adjustment broadcast to the bluetooth gateway, and after receiving the second power adjustment broadcast, the bluetooth gateway responds to the second power adjustment broadcast and sends the response information carrying the signal strength of the connection between the bluetooth terminal and the bluetooth gateway, which is detected by the bluetooth gateway, to the bluetooth terminal.
It should be noted that, the bluetooth terminal receives the response information carrying the signal strength of the connection between the bluetooth terminal and the bluetooth gateway detected by the bluetooth gateway again, and detects that the signal strength carried in the response information is still greater than the first threshold, the above operations are continuously executed, that is, the transmission power of the bluetooth terminal continues to decrease according to the level, the bluetooth terminal continues to send the third power adjustment broadcast to the bluetooth gateway, and after receiving the third power adjustment broadcast, the bluetooth gateway responds to the third power adjustment broadcast and sends the response information carrying the signal strength of the connection between the bluetooth terminal and the bluetooth gateway detected by the bluetooth gateway to the bluetooth terminal until the signal strength in the response information is less than the preset threshold, so that the bluetooth terminal is connected with only one bluetooth gateway.
In an exemplary embodiment, after the transmission power of the bluetooth terminal is adjusted according to the at least two signal strengths so that the bluetooth terminal is connected to a target bluetooth gateway of the at least two bluetooth gateways, a sending module is configured to send a first gateway probe broadcast to the bluetooth gateways according to a preset period; and under the condition that the Bluetooth terminal does not receive a gateway probe response of the Bluetooth gateway to the first gateway probe broadcast in the preset period, an adjusting module adjusts the transmitting power of the Bluetooth terminal to a third transmitting power by one level.
After the transmission power of the Bluetooth terminal is adjusted, the Bluetooth terminal starts a Bluetooth gateway probe at regular time, and sends a first gateway probe broadcast to the Bluetooth gateway according to a preset period, if the Bluetooth terminal does not receive a gateway probe response of the Bluetooth gateway to the first gateway probe broadcast in the preset period, that is, no Bluetooth gateway receives the first gateway probe broadcast sent by the Bluetooth terminal, that is, no Bluetooth gateway can receive measurement parameters sent by the Bluetooth device at the moment, and then the transmission power of the Bluetooth terminal needs to be increased by one level to a third transmission power, so that the Bluetooth gateway can receive the first gateway probe broadcast sent by the Bluetooth terminal, and if the Bluetooth terminal receives the gateway probe response of the Bluetooth gateway to the first gateway probe broadcast in the preset period, the Bluetooth terminal continues to maintain a second transmission power.
In an exemplary embodiment, after the transmission power of the bluetooth terminal is increased by one level to a third transmission power, the sending module sends a second gateway probe broadcast to the bluetooth gateway based on the third transmission power; and under the condition that the Bluetooth terminal does not receive a gateway probing response of the Bluetooth gateway to the second gateway probing broadcast in the preset period, adjusting the third transmitting power of the Bluetooth terminal to the default power of the Bluetooth terminal by an adjusting module.
Specifically, after the transmission power of the bluetooth terminal is increased by one level to a third transmission power, the bluetooth terminal continues to send a second gateway probe broadcast, if the bluetooth terminal receives a gateway probe response of the bluetooth gateway to the second gateway probe broadcast within a preset period, the bluetooth terminal keeps transmitting the third transmission power to the bluetooth gateway, and if the bluetooth terminal does not receive the gateway probe response of the bluetooth gateway to the second gateway probe broadcast within the preset period, the third transmission power of the bluetooth terminal is adjusted to the default power of the bluetooth terminal, which may be factory power, where the default power is not limited in the embodiment of the present invention.
Further, if the bluetooth terminal does not receive a gateway probe response of the bluetooth gateway to the second gateway probe broadcast within the preset period, the adjusting module may further increase the transmission power of the bluetooth terminal by one level to a fourth transmission power again, so that the bluetooth gateway may receive the gateway probe broadcast sent by the bluetooth terminal.
