The following describes a method and an apparatus for controlling a bluetooth low energy device according to the present invention with reference to fig. 1 to 6.
Fig. 1 is a schematic flow chart of a bluetooth low energy device control method provided by the present invention, as shown in fig. 1, including:
step S1, under the condition that a plurality of first pre-selected Bluetooth low energy gateways with the Bluetooth low energy device proxy function exist, calculating the comprehensive network quality score value of each first pre-selected Bluetooth low energy gateway, wherein the first pre-selected Bluetooth low energy gateways report the data information of the Bluetooth low energy devices to a cloud platform and are in an online state;
specifically, the Bluetooth Low Energy (BLE) device described in the present invention refers to a terminal device using BLE technology, such as a switch, a socket, a lamp, a lock and other BLE smart devices supporting BLE control.
Usually, the BLE device does not have the capability of being connected with the internet independently, and at this time, a relay communication device needs to be introduced to report data of the BLE device and issue a control instruction of an internet cloud platform.
The BLE gateway in the embodiment of the present invention is a device for providing relay communication between a BLE device and an internet cloud platform.
The first pre-selected BLE gateway described in the present invention refers to a BLE gateway that satisfies three conditions, namely, a Bluetooth low energy device proxy function, and reports data information of a Bluetooth low energy device to a cloud platform, and the BLE gateway is in an online state.
The Bluetooth low-power-consumption device proxy function described in the invention specifically means that if BLE devices communicate by adopting BLE connection, a BLE gateway must have the function of BLE connection, and the BLE gateway can analyze data of the BLE devices according to a protocol; the BLE gateway and the BLE device can be bound under the same user or in the same family;
the data information of the Bluetooth low-power consumption device reported to the cloud platform described by the invention means that the BLE gateway reports the data of the BLE device in the original data of the Internet cloud platform.
In an embodiment of the application, the first pre-selected BLE gateway may receive data of the BLE device and report the data to the cloud platform, and the cloud platform may store all data, such as the data of the BLE device reported by the first pre-selected BLE gateway, and store the data as raw data.
The online state described in the present invention refers to a connection state between an intelligent device, such as a BLE gateway, and a cloud platform, and if the intelligent device and the cloud platform are connected to each other, the connection state is referred to as "online"; the intelligent device is disconnected from the cloud platform, and the connection is called as off-line; if the cloud platform is notified before the smart device enters the low power consumption or sleep mode, the cloud platform may also record the state of the device as "sleep".
The integrated network quality score value described in the invention is obtained by calculation based on the signal strength between the first pre-selected BLE gateway and the cloud platform and between the first pre-selected BLE gateway and the BLE device, and can be used for evaluating the integrated network quality of the BLE gateway.
Further, in the case where there are a plurality of first pre-selected BLE gateways, an aggregate network quality score value is calculated for each of the first pre-selected BLE gateways.
Step S2, according to the comprehensive network quality score value of each first pre-selected Bluetooth low energy gateway, determining a second pre-selected Bluetooth low energy gateway corresponding to the minimum comprehensive network quality score value;
specifically, according to the characteristics of the signal strength of the receiving end, the signal strength of the receiving end is generally a negative value, and the smaller the value, the better the representative sensitivity is, and therefore, the smaller the integrated network quality score value of the first preselected bluetooth low energy gateway is, the better the integrated network quality thereof is.
Further, after calculating the comprehensive network quality score value of each first pre-selected Bluetooth low energy gateway, determining the minimum comprehensive network quality score value.
The second pre-selected bluetooth low energy gateway described herein refers to a BLE gateway corresponding to the minimum integrated network quality score value.
Step S3, determining a master agent bluetooth low energy gateway of the bluetooth low energy device based on the second pre-selected bluetooth low energy gateway.
Specifically, the master-agent bluetooth low energy gateway described in the present invention is a BLE gateway for issuing a control instruction to BLE devices to effectively control the BLE devices.
After the second pre-selected BLE gateway is determined, the primary proxy BLE gateway of the BLE device can be determined through analysis of data information reported by the second pre-selected BLE gateway in the cloud platform raw data.
According to the method provided by the embodiment of the invention, the first pre-selected BLE gateway has the function of acting on BLE equipment, reports data information of the BLE equipment to the cloud platform, and calculates the comprehensive network quality of the first pre-selected BLE gateway by combining a plurality of factors such as the signal intensity of the first pre-selected BLE gateway and the signal intensity of the BLE equipment on the basis of the online state; the method comprises the steps of determining a second pre-selected BLE gateway corresponding to the minimum comprehensive network quality based on the characteristics of the receiving end comprehensive network quality, and then screening out a main proxy BLE gateway from the second pre-selected BLE gateway in real time, avoiding the situation that the BLE equipment cannot be controlled after the BLE gateway is removed, issuing a control instruction to the BLE equipment through the main proxy gateway, and realizing effective control on the BLE equipment in a complex and changeable network environment, such as increase or decrease of gateways, enhancement or decrease of signal strength, online or offline of gateways and the like.
Optionally, the calculating the integrated network quality score value of each of the first pre-selected bluetooth low energy gateways includes:
acquiring a signal intensity data set and an optimization parameter data set of each first pre-selected Bluetooth low energy gateway, wherein the signal intensity data set comprises a first signal intensity value and a second signal intensity value, and the first signal intensity value is a signal intensity value between the first pre-selected Bluetooth low energy gateway and the cloud platform; the second signal strength value is a signal strength value between the first pre-selected bluetooth low energy gateway and the bluetooth low energy device; the optimized parameter data set comprises at least one of a network connectivity performance parameter and a network round trip delay parameter of the first pre-selected Bluetooth low energy gateway;
and calculating the comprehensive network quality score value of each first pre-selected Bluetooth low energy gateway according to the signal intensity data set and the optimization parameter data set.
Specifically, from the signal strength data set, an integrated network quality score value for each first pre-selected bluetooth low energy gateway may be calculated.
In an embodiment of the present invention, the raw data of the cloud platform includes data reported by the first pre-selected BLE gateway, which mainly includes two parts of data:
the first part of data is self data of the first pre-selected BLE gateway, including but not limited to proxy capability of the BLE gateway, Signal Strength between the BLE gateway and the cloud platform, which can be represented by Received Signal Strength Indication (RSSI), wherein the RSSI is used for determining connection quality of the device; wide area network connectivity of a BLE gateway; local area network connectivity of a BLE gateway; a wide area network round-trip delay (ms) of a BLE gateway; the local area network round-trip delay (ms) of the BLE gateway, and the like. If the first pre-selected BLE gateway cannot directly report the RSSI, the cloud platform needs to convert the signal strength reference value (strengthh) into the RSSI according to an applicable algorithm according to the signal strength reference value (strengthh) reported by the first pre-selected BLE gateway, and then store the RSSI as original data of the signal strength of the first pre-selected BLE gateway.
The second part of data is proxy data of the BLE gateway, including but not limited to received BLE device data, signal strength between the BLE device and the BLE gateway (RSSI), and the like.
Therefore, according to the original data information of the cloud platform, a signal strength indicator (RSSI) value between the last reported first pre-selected BLE gateway and the cloud platform can be determined, that is, a first signal strength value RSSI _ GC is obtained; and determining the signal strength (RSSI) value between the first pre-selected BLE gateway and the BLE device, which is reported by the last proxy, to obtain a second signal strength value RSSI _ GD, and the signal strength data group is (RSSI _ GC, RSSI _ GD).
Further, the RSSI-GC and RSSI-GD of the first preset BLE gateway may be weighted to obtain an integrated network quality score value RSSI _ T between the first preset BLE gateway and the cloud platform, and between the first preset BLE gateway and the BLE device in the network path, that is, the integrated network quality score value RSSI _ T is obtained
RSSI_T＝(0－RSSI_GC)×M+(0－RSSI_GD)×N；
And M + N is 100%, and the specific numerical values of M and N can be adjusted according to big data analysis on the actual operation conditions of the BLE gateway and the BLE device, but the sum of the M and the N is kept constant at 100%.
As can be known from the characteristics of the RSSI at the receiving end, the smaller the RSSI _ T value is, the better the comprehensive network quality of the first preset BLE gateway is.
Exemplarily, in an embodiment of the present invention, it is assumed that there are 3 first pre-selected BLE gateways, namely BLE gateway A, BLE gateway B, BLE gateway C. Table 1 shows RSSI _ GC and RSSI _ GD data information of BLE gateway A, BLE, gateway B and BLE gateway C, respectively, in the raw data of the cloud platform provided in the present invention.
TABLE 1
As shown in the second column of data in table 1, RSSI _ GC between BLE gateway A, BLE gateway B, BLE gateway C and the cloud platform, respectively, can be determined.
As shown in the third column of data in table 1, the RSSI _ GD between BLE gateway A, BLE gateway B, BLE gateway C and BLE devices, respectively, may be determined.
According to the above weighted calculation formula of RSSI _ T, the RSSI _ T value of each gateway can be obtained, as shown in the fourth column of data in table 1.
Through calculation, the RSSI _ T value of the BLE gateway a is 55, which is the minimum value of the three BLE gateways, that is, the BLE gateway a serves as the master proxy gateway for issuing the instruction to the BLE device at this time.
Preferably, according to the richness of the device data, the invention supports that the network connectivity β of the BLE gateway is included in the calculation range, that is, the optimization parameter data set can be determined as the at least one item of data in the data set as β. In embodiments of the present invention, network connectivity refers to the network connectivity of a device, and generally, a higher value in% indicates a better network connectivity of the device.
Further, a weighting calculation is performed together with the signal strength data sets (RSSI _ GC, RSSI _ GD), so that a more comprehensive result of the network signal quality of the master proxy gateway can be obtained, and at this time:
RSSI_T＝(0－RSSI_GC)×M+(0－RSSI_GD)×N+(1－β)×Y；
wherein M + N + Y is 100%.
Preferably, the present invention further supports to also include the network round trip delay t (ms) of the BLE gateway into the calculation range, that is, the optimization parameter data set may be determined as the at least one item of data in the data set as t. In the embodiment of the present invention, the network round trip delay represents the network transmission delay of the device, and the smaller the value is, the better the network performance is.
Similarly, performing the weighting calculation together with the signal strength data sets (RSSI _ GC, RSSI _ GD) can obtain a more comprehensive result of the network signal quality of the master proxy gateway, when:
RSSI_T＝(0－RSSI_GC)×M+(0－RSSI_GD)×N+t×Z；
wherein M + N + Z is 100%.
Furthermore, the invention also supports the simultaneous inclusion of the network connectivity beta and the network round trip delay t (ms) of the BLE gateway into the calculation range, i.e. the optimized parameter data set (beta, t) can be determined. The optimized parameter data set (β, t) and the signal strength data set (RSSI _ GC, RSSI _ GD) are weighted to obtain a more comprehensive result of the network signal quality of the master proxy gateway, and at this time:
RSSI_T＝(0－RSSI_GC)×M+(0－RSSI_GD)×N+(1－β)×Y+t×Z；
wherein, M + N + Y + Z is 100%.
Thus, the RSSI _ T calculated by the above method is a comprehensive network signal index combining data such as BLE gateway signal strength, BLE device signal strength, BLE gateway network connectivity, and BLE gateway network round trip delay.
In the embodiment of the invention, the strategy for selecting the BLE device master proxy gateway is continuously optimized according to the statistical analysis of the device control data based on the richness of the device data, and the strategy can be effective in real time after being updated because the strategy is maintained by a cloud platform.
According to the method provided by the embodiment of the invention, based on the richness of the equipment data, a comprehensive network signal index combining data such as BLE gateway signal strength, BLE equipment signal strength, BLE gateway network connectivity, BLE gateway network round-trip delay and the like can be obtained through weighting calculation, and the complex and variable network environment can be better dealt with, so that the most suitable BLE equipment master proxy gateway can be accurately selected when the network environment changes.
Optionally, the determining a master agent bluetooth low energy gateway of the bluetooth low energy device based on the second pre-selected bluetooth low energy gateway includes:
under the condition that a plurality of second preselected Bluetooth low-power gateways exist, determining a third preselected Bluetooth low-power gateway based on the data reporting time of each second preselected Bluetooth low-power gateway in the original data information of the cloud platform;
determining a master agent Bluetooth Low energy gateway for the Bluetooth Low energy device based on the third pre-selected Bluetooth Low energy gateway.
Specifically, the presence of a plurality of second pre-selected bluetooth low energy gateways described herein refers to the presence of a plurality of second pre-selected BLE gateways with the same minimum integrated network quality score value.
The original data information of the cloud platform described in the invention comprises the data of each BLE gateway, and BLE equipment data and reporting time reported by each BLE gateway agent. In this application embodiment, the pan-tilt head stores the data as original data, and updates the original data in real time, so as to provide data support for a primary proxy BLE gateway that selects BLE devices.
The third preselected bluetooth low energy gateway described in the present invention refers to a BLE gateway determined from a plurality of second preselected bluetooth low energy gateways according to corresponding data reporting time in the raw data information of the cloud platform.
The data reporting time described in the present invention refers to a time when the second pre-selected BLE gateway reports data to the cloud platform and the cloud platform receives the reported data.
Further, after the data reporting time of each second pre-selected bluetooth low energy gateway is determined, a BLE gateway which reports data most recently, that is, a BLE gateway whose data reporting time is closest to the current time, is selected as a third pre-selected BLE gateway.
Further, based on the third pre-selected BLE gateway, a primary BLE gateway for the BLE device is determined. At this time, if there is only one third pre-selected BLE gateway, the third pre-selected BLE gateway is used as a primary proxy BLE gateway of the BLE device; if there are multiple third pre-selected BLE gateways, that is, there are multiple last-reported BLE gateways, and the data reporting times of the multiple last-reported BLE gateways are the same, in this case, one of the multiple third pre-selected BLE gateways may be randomly selected as a primary proxy BLE gateway of the BLE device.
According to the method provided by the embodiment of the invention, the data reporting time of the second pre-selected BLE gateway is determined by calling the original data of the cloud platform, and then the master proxy BLE gateway of the BLE equipment is determined by comparing the data reporting times, so that the condition that a plurality of second pre-selected BLE gateways exist can be effectively dealt with, and the most suitable master proxy BLE gateway is selected.
Optionally, the determining a master agent bluetooth low energy gateway of the bluetooth low energy device based on the second pre-selected bluetooth low energy gateway includes:
and under the condition that one second pre-selected Bluetooth low energy gateway exists, taking the second pre-selected Bluetooth low energy gateway as a master agent Bluetooth low energy gateway of the Bluetooth low energy equipment.
According to the method provided by the embodiment of the invention, the second pre-selected BLE gateway is used as the strategy of the primary proxy BLE gateway of the BLE device, so that the situation that only one second pre-selected BLE gateway exists can be effectively dealt with.
Optionally, in the presence of one of the first pre-selected bluetooth low energy gateways, the method further comprises:
and taking the first pre-selected Bluetooth low energy gateway as a master agent Bluetooth low energy gateway of the Bluetooth low energy equipment.
According to the method provided by the embodiment of the invention, the first pre-selected BLE gateway is used as the strategy of the primary proxy BLE gateway of the BLE device, so that the situation that only one first pre-selected BLE gateway exists can be effectively dealt with.
