For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes a control method and a device for bluetooth low energy equipment according to the present invention with reference to fig. 1 to 6.
Fig. 1 is a flow chart of a control method of a bluetooth low energy device according to the present invention, as shown in fig. 1, including:
step S1, under the condition that a plurality of first pre-selected Bluetooth low-power consumption gateways with Bluetooth low-power consumption equipment proxy functions exist, calculating a comprehensive network quality score value of each first pre-selected Bluetooth low-power consumption gateway, wherein the first pre-selected Bluetooth low-power consumption gateways report data information of Bluetooth low-power consumption equipment to a cloud platform and are in an online state;
in particular, bluetooth low energy (Bluetooh Low Energy, BLE) devices described herein refer to terminal devices that use BLE technology, such as switches, sockets, luminaires, locks, and other BLE smart devices that support BLE control.
In general, the BLE device does not have the capability of connecting to the internet alone, and a relay communication device needs to be introduced to report data of the BLE device and issue control instructions of the 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 by the invention is a BLE gateway which meets the three conditions of having the function of proxy of Bluetooth low-power-consumption equipment and reporting data information of the Bluetooth low-power-consumption equipment to a cloud platform and being in an on-line state.
The function of the Bluetooth low-power-consumption device proxy described by the invention specifically means that if BLE devices communicate by 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 BLE device may be bound under the same user or within the same home;
the data information reported to the cloud platform by the Bluetooth low-power consumption device described by the invention means that in the original data of the Internet cloud platform, the BLE gateway is present to report the data of the BLE device.
In the 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, where the cloud platform may store all data of the BLE device reported by the first pre-selected BLE gateway, and store the data as original data.
The online state described in the invention refers to a connection state between an intelligent device, such as a BLE gateway, and a cloud platform, and is called online if the intelligent device and the cloud platform are connected; the intelligent equipment and the cloud platform are disconnected, namely "offline"; if the cloud platform is notified before the intelligent device enters the low power consumption or sleep mode, the cloud platform can record the state of the device as sleep.
The comprehensive network quality score value is calculated based on the signal intensity between the first preselected BLE gateway, the cloud platform and the BLE equipment, and can be used for evaluating the quality of the comprehensive network quality of the BLE gateway.
Further, in the presence of a plurality of first pre-selected BLE gateways, a composite network quality score value is calculated for each of the first pre-selected BLE gateways.
S2, determining a second pre-selected Bluetooth low energy gateway corresponding to the minimum comprehensive network quality score value according to the comprehensive network quality score value of each first pre-selected Bluetooth low energy gateway;
specifically, as known from the signal strength of the receiving end, the signal strength of the receiving end is generally negative, the smaller the value is, the better the representative sensitivity is, and therefore, the smaller the comprehensive network quality score value of the first pre-selected bluetooth low energy gateway is, the better the comprehensive network quality is.
Further, after calculating the integrated network quality score value of each first pre-selected bluetooth low energy gateway, a minimum integrated network quality score value is determined.
The second pre-selected bluetooth low energy gateway described in the present invention refers to a BLE gateway corresponding to the minimum integrated network quality score value.
And 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 bluetooth low energy gateway with the master agent described in the present invention is a BLE gateway for issuing a control command to a BLE device to effectively control the BLE device.
After the second pre-selected BLE gateway is determined, the master proxy BLE gateway of the BLE device can be determined through data information analysis on the second pre-selected BLE gateway in the cloud platform original data.
According to the method, the first pre-selected BLE gateway has the function of proxy BLE equipment, data information of the BLE equipment is reported to the cloud platform and is in an on-line state, and the comprehensive network quality of the first pre-selected BLE gateway is calculated by combining a plurality of factors such as signal strength of the first pre-selected BLE gateway and signal strength of the BLE equipment; based on the characteristics of the comprehensive network quality of the receiving end, a second preselected BLE gateway corresponding to the minimum comprehensive network quality is determined, and then the main proxy BLE gateway can be selected from the second preselected BLE gateways in real time, so that the situation that BLE equipment cannot be controlled after the BLE gateway is removed is avoided, a control instruction is issued to the BLE equipment through the main proxy BLE gateway, and effective control over the BLE equipment in complex and changeable network environments such as increase or decrease of the gateway, enhancement or weakening of signal intensity, online or offline of the gateway and the like is realized.
Optionally, said calculating a composite network quality score value for each of said first pre-selected bluetooth low energy gateways includes:
acquiring a signal strength data set and an optimization parameter data set of each first pre-selected Bluetooth low energy gateway, wherein the signal strength data set comprises a first signal strength value and a second signal strength value, and the first signal strength value is a signal strength 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 network connectivity performance parameters and network round trip delay parameters 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 strength data set and the optimization parameter data set.
Specifically, from the signal strength data set, a composite network quality score value for each first pre-selected bluetooth low energy gateway may be calculated.
In the embodiment of the invention, the original data of the cloud platform comprises data reported by a first pre-selected BLE gateway, and the data mainly comprises two parts of data:
The first portion of data is self data of the first preselected BLE gateway including, but not limited to, proxy capability of the BLE gateway, signal strength between the BLE gateway and the cloud platform, which may be represented using a received signal strength indication (Received Signal Strength Indication, RSSI), wherein the RSSI is used to determine connection quality of the device; wide area network connectivity of BLE gateway; local area network connectivity of BLE gateway; a wide area network round trip delay (ms) of the BLE gateway; local area network round trip delay (ms) of BLE gateway, etc. If the first pre-selected BLE gateway cannot directly report the RSSI, the cloud platform needs to convert the signal strength reference value (strength) into the RSSI according to the signal strength reference value (strength) reported by the first pre-selected BLE gateway and then store the RSSI as the original data of the signal strength of the first pre-selected BLE gateway.
The second portion of data is proxy data for the BLE gateway including, but not limited to, received BLE device data, signal strength (RSSI) between the BLE device and the BLE gateway, and the like.
Therefore, according to the original data information of the cloud platform, the signal strength (RSSI) value between the cloud platform and the first pre-selected BLE gateway, which is reported last time, can be determined, and the first signal strength value RSSI_GC is obtained; and determining the signal strength (RSSI) value between the BLE equipment and the last proxy of the first preselected BLE gateway, namely obtaining a second signal strength value RSSI_GD, wherein the signal strength data set is (RSSI_GC, RSSI_GD).
Furthermore, the RSSI-GC and RSSI-GD of the first preset BLE gateway can be weighted to obtain a comprehensive 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, namely
RSSI_T＝(0－RSSI_GC)×M+(0－RSSI_GD)×N；
Wherein, m+n=100%, and the specific values of M and N can be adjusted according to big data analysis on the actual BLE gateway and BLE device operation conditions, but the sum of the two is kept to be 100%.
As can be seen from the RSSI characteristic of the receiving end, the smaller the RSSI_T value is, the better the comprehensive network quality of the first preset BLE gateway is.
Illustratively, 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 is the rssi_gc and rssi_gd data information of each of the BLE gateway A, BLE gateway B and the BLE gateway C in the original data of the cloud platform provided by the present invention.
TABLE 1
As shown by the second column data in table 1, the rssi_gc between BLE gateway A, BLE gateway B, BLE gateway C and the cloud platform, respectively, may be determined.
As shown in the third column of data in table 1, the rssi_gd between the BLE gateway A, BLE gateway B, BLE gateway C and the BLE devices, respectively, may be determined.
According to the weighted calculation formula of rssi_t, the rssi_t value of each gateway can be obtained, as shown in the fourth column data in table 1.
The calculated rssi_t value of BLE gateway a is 55, which is the smallest value of the three BLE gateways, i.e., BLE gateway a is the master proxy gateway that issues the instruction to the BLE device this time.
Preferably, the present invention supports the inclusion of the network connectivity β of the BLE gateway into the calculation range, i.e. it is possible to determine that the optimized parameter data set is β for at least one item of data in the data set, depending on the richness of the device data. In an embodiment of the present invention, network connectivity represents the network connection situation of a device, usually in% and the higher its value, the better the network connection situation of the device.
Further, the weighting calculation is performed together with the signal strength data set (rssi_gc, rssi_gd), so as to obtain a more comprehensive network signal quality result of the home agent gateway, where:
RSSI_T＝(0－RSSI_GC)×M+(0－RSSI_GD)×N+(1－β)×Y；
wherein m+n+y=100%.
Preferably, the present invention also supports that the network round trip delay t (ms) of the BLE gateway is also included in the calculation range, i.e. it can be determined that the optimized parameter data set is t for at least one item of data in the data set. In the embodiment of the invention, the network round trip delay represents the network transmission delay of the device, and the smaller the value of the network round trip delay is usually in ms (milliseconds), the smaller the network transmission delay is, and the better the network performance is.
Similarly, weighting calculations along with the signal strength data set (rssi_gc, rssi_gd) may yield a more comprehensive result of the network signal quality of the primary proxy gateway, at which point:
RSSI_T＝(0－RSSI_GC)×M+(0－RSSI_GD)×N+t×Z；
wherein m+n+z=100%.
Further, the invention also supports the simultaneous inclusion of the network connectivity β and the network round trip delay t (ms) of the BLE gateway into the calculation range, i.e. the optimization parameter data set (β, t) can be determined. Weighting the optimization parameter data set (β, t) together with the signal strength data set (rssi_gc, rssi_gd) yields a more comprehensive result of the network signal quality of the primary proxy gateway, when:
RSSI_T＝(0－RSSI_GC)×M+(0－RSSI_GD)×N+(1－β)×Y+t×Z；
wherein m+n+y+z=100%.
In this way, the rssi_t calculated by the above method is a comprehensive network signal indicator that combines 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 policy for selecting the BLE equipment main proxy gateway is continuously optimized according to the statistical analysis of the equipment control data based on the richness of the equipment data, and the policy can be effective in real time after being updated because the policy is maintained on the 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 the 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 weighted calculation, complex and changeable network environments can be better dealt with, and therefore, the most suitable BLE equipment main proxy gateway can be accurately selected when the network environments change.
Optionally, the determining, based on the second pre-selected bluetooth low energy gateway, a master proxy bluetooth low energy gateway of the bluetooth low energy device includes:
under the condition that a plurality of second pre-selected Bluetooth low-power consumption gateways exist, determining a third pre-selected Bluetooth low-power consumption gateway based on the data reporting time of each second pre-selected Bluetooth low-power consumption gateway in the original data information of the cloud platform;
and determining a master proxy Bluetooth low energy gateway of the Bluetooth low energy device based on the third pre-selected Bluetooth low energy gateway.
In particular, the presence of a plurality of second pre-selected bluetooth low energy gateways as described herein refers to the presence of a plurality of second pre-selected BLE gateways having the same minimum integrated network quality score.
The original data information of the cloud platform described by the invention comprises self data of each BLE gateway and BLE equipment data and reporting time reported by each BLE gateway proxy. In this embodiment of the present application, the platform stores the data as original data and updates the original data in real time, so as to provide data support for a master proxy BLE gateway for selecting BLE devices.
The third pre-selected Bluetooth low-power consumption gateway described in the invention refers to a BLE gateway determined from a plurality of second pre-selected Bluetooth low-power consumption gateways according to corresponding data reporting time in original data information of a cloud platform.
The data reporting time described by the invention refers to the time when the second pre-selected BLE gateway reports data to the cloud platform and the cloud platform receives the reported data.
Further, after determining the data reporting time of each second pre-selected bluetooth low energy gateway, a BLE gateway in which data is recently reported, that is, a BLE gateway in which the data reporting time is closest to the current time, is selected as a third pre-selected BLE gateway.
Further, a primary BLE gateway for the BLE device is determined based on the third pre-selected BLE gateway. At this time, if only one third pre-selected BLE gateway exists, the third pre-selected BLE gateway is used as a master proxy BLE gateway of the BLE device; if there are multiple third pre-selected BLE gateways, that is, there are multiple BLE gateways that report data recently, and the time for reporting data is the same, in this case, one of the multiple third pre-selected BLE gateways is selected randomly as the master proxy BLE gateway of the BLE device.
According to the method, the data reporting time of the second preselected 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 time, so that the situation that a plurality of second preselected BLE gateways exist can be effectively dealt with, and the most suitable master proxy BLE gateway is selected.
Optionally, the determining, based on the second pre-selected bluetooth low energy gateway, a master proxy bluetooth low energy gateway of the bluetooth low energy device includes:
and under the condition that one second pre-selected Bluetooth low energy gateway exists, the second pre-selected Bluetooth low energy gateway is used as a main proxy Bluetooth low energy gateway of the Bluetooth low energy device.
The method of the embodiment of the invention can effectively cope with the situation that only one second pre-selected BLE gateway exists by taking the second pre-selected BLE gateway as the strategy of the master proxy BLE gateway of BLE equipment.
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 main proxy Bluetooth low energy gateway of the Bluetooth low energy device.
The method of the embodiment of the invention can effectively cope with the situation that only one first pre-selected BLE gateway exists by taking the first pre-selected BLE gateway as the strategy of the master proxy BLE gateway of BLE equipment.
