Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In a bluetooth wireless communication system including a plurality of mobile devices and a plurality of fixed devices, the communication between the mobile devices and the fixed devices needs to be kept stable and orderly, and matching association between the mobile devices and the fixed devices is required. One method that is more common in the art is to use correlation manually or with the aid of peripheral devices (nfc, PC, phone, etc.).
However, as the number of mobile devices and fixed devices in a wireless communication system increases, the workload is greatly increased by establishing a connection between the mobile devices and the fixed devices using a conventional method; moreover, when the wireless communication system is deployed and implemented, the workers also face greater challenges, increasing the difficulty of deployment, implementation and maintenance.
In addition, the traditional method of establishing connection manually can greatly improve the error probability caused by manual participation.
It should be noted that, the mobile device mentioned in this embodiment of the present application refers to a bluetooth slave device, and may actively send a broadcast request signal to a bluetooth gateway, or perform data interaction with the bluetooth gateway through a connection method. The fixed equipment is a Bluetooth main equipment which can receive and transmit Bluetooth signals and communicate with the Bluetooth equipment. Such as bluetooth gateways, cell phones, etc.
The embodiment of the application provides a BLE-based adaptive association networking method and equipment, which aim to solve the problem that the workload is increased sharply when the conventional Bluetooth connection method is applied to a multi-equipment wireless communication system; and when deployment is carried out, inconvenience is brought to installation and maintenance of workers; and the error rate can be greatly improved due to the manual participation. The technical solutions provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1 is a schematic view of a topology of a multi-device wireless communication system according to an embodiment of the present disclosure. As shown in fig. 1, the wireless communication system includes a plurality of fixed devices such as a fixed device 1, a fixed device 2, and a fixed device 3, and a plurality of types of mobile devices. Wherein the number of mobile devices of each type is variable. And a plurality of fixed devices can communicate with the upper server and upload data information sent by various types of mobile devices.
When a mobile device needs to communicate with a fixed device, the mobile device issues an association request broadcast with multiple fixed devices. The association request broadcast can be received by a plurality of fixed devices, the mobile device establishes connection with the fixed devices as much as possible, and when the mobile device is successfully associated with the fixed device with the strongest received signal strength, the communication process between the mobile device and the fixed device can be orderly. The specific implementation process is shown in fig. 2.
Fig. 2 is a schematic flowchart of a method for adaptive association networking based on BLE according to an embodiment of the present disclosure.
As shown in fig. 2, an adaptive association networking method based on BLE according to an embodiment of the present application is implemented by the following steps:
In a wireless communication system including a plurality of mobile devices and a plurality of fixed devices, when the mobile devices need to communicate with the fixed devices or the mobile devices need to upload data information to a server, the mobile devices send out association request broadcast with the fixed devices.
In one embodiment of the present application, the association request broadcast from the mobile device includes information about the mobile device.
In another embodiment of the application, the relevant information of the mobile device includes any one or more of: device code of the mobile device, MAC address of the mobile device, device name of the mobile device.
Further, after the mobile device sends out an association request broadcast including the related information of the mobile device, the plurality of fixed devices identify whether the mobile device belongs to the wireless communication system in which the fixed device is located or determine whether the mobile device and the fixed device belong to one manufacturer by associating the related information of the mobile device included in the request broadcast.
Furthermore, when the fixed devices successfully identify the association request broadcast information sent by the mobile device through the pre-stored relevant information of the mobile device, the fixed devices can all successfully establish connection with the mobile device.
In step 202, the mobile device establishes a connection with n fixed devices in the plurality of fixed devices through BLE.
The mobile device establishes a connection relationship with n fixed devices of the plurality of fixed devices through Bluetooth Low Energy (BLE). Wherein n is more than 1 and less than or equal to the number of the plurality of fixed devices.
In one embodiment of the present application, the plurality of fixed devices refer to fixed devices that have received the association request broadcast and that, based on the pre-stored relevant information of the mobile device, identify the fixed device that successfully associates the information in the request broadcast.
In one embodiment of the present application, the association request broadcast is received by multiple fixed devices in the same communication system after the mobile device issues the association request broadcast. When several fixed devices receive the association request broadcast and identify information in the successful association request broadcast, the several fixed devices may all attempt to connect to the mobile device that originated the association request broadcast. And the mobile device has the capability of establishing connection with one or more fixed devices, and when the association request broadcast sent by the mobile device is received by a plurality of fixed devices and the identification is successful, the mobile device can establish connection with the fixed devices as much as possible.
However, since the number of fixed devices to which the mobile device can connect through BLE is limited, the mobile device establishes a connection with n fixed devices of several fixed devices.
For example, the wireless communication system includes 20 fixed devices, and among them, there are 12 related information broadcast by the association request sent by the mobile device, identifying the successful mobile device, and determining that the mobile device and the fixed device belong to the same manufacturer or the same wireless communication system. But the mobile device can only establish connection relation with 4 fixed devices at the same time through BLE. Therefore, the mobile device will first establish a connection relationship with 4 fixed devices out of 12 fixed devices.
It should be noted that n fixed devices of the plurality of fixed devices connected to the mobile device may be connected by random selection, may also be connected according to the sequence of the identification of the successful associated broadcast, and may also be connected by selection according to other setting conditions, which is not limited in this application.
After the mobile device establishes connection with n fixed devices of the plurality of fixed devices, the mobile device receives relevant information of the corresponding fixed devices sent by the n fixed devices connected with the mobile device through BLE, and receives Received Signal Strength Indication (rssi) of the n fixed devices connected with the mobile device.
In one embodiment of the present application, the related information of the fixed device recorded by the mobile device corresponds to the rssi of the recorded fixed device one to one.
And, the mobile device can uniquely determine the related information of the fixed device corresponding to the rssi through the rssi of the fixed device.
In one embodiment of the present application, the information about the fixed device is used to enable the mobile device to record the fixed device that has established an over-connection with the mobile device through BLE. And after the mobile device sends the association request broadcast once, the mobile device does not repeatedly establish a connection relationship with one or more fixed devices through BLE until the next association request broadcast is sent.
In one embodiment of the application, the information related to the fixed device comprises any one or more of: the device code of the fixed device, the device name of the fixed device, and the MAC address of the fixed device.
In another embodiment of the application, the mobile device records rssis of the n fixed devices connected to the mobile device, and the recorded rssis are sorted in descending order to determine the strongest rssi of the n fixed devices connected to the mobile device.
And step 204, the mobile device traverses a plurality of fixed devices by taking the number of the fixed devices smaller than or equal to n as a basic unit.
After the mobile device establishes a connection relationship with n fixed devices of the plurality of fixed devices and records the relevant information and the rssi of the n fixed devices connected with the mobile device, the mobile device traverses the plurality of fixed devices to determine the strongest rssi of the plurality of fixed devices, so that the mobile device establishes a connection relationship with the fixed device corresponding to the strongest rssi of the plurality of fixed devices.
The mobile device traverses a plurality of fixed devices, which can be realized by the following two ways:
mode 1: and traversing a plurality of fixed devices by taking the n fixed devices as basic units.
In one embodiment of the application, the mobile device disconnects from n fixed devices in the fixed devices, and establishes a connection relationship with n fixed devices in the remaining fixed devices, which are not connected with the mobile device through BLE, in the fixed devices.
In one embodiment of the application, the mobile device determines, through the recorded information about the fixed devices with which the connection was established, information about remaining fixed devices, from among the plurality of fixed devices, with which the connection was not established through BLE, of the mobile device.
Further, after the mobile device and the n fixed devices in the remaining fixed devices successfully establish a connection relationship through BLE, the relevant information of the corresponding fixed devices sent by the n fixed devices in the remaining fixed devices through BLE and the rsi of the n fixed devices in the remaining fixed devices are received. Wherein n is greater than 1 and less than or equal to the number of remaining fixtures.
Further, the mobile device disconnects from the n fixed devices of the remaining fixed devices.
Further, the mobile device determines again the related information of the rest of the plurality of fixed devices which are not in the connection relationship with the mobile device through the BLE until all of the plurality of fixed devices are in the connection relationship with the mobile device through the BLE.
It should be noted that, the fixed devices herein refer to the fixed devices that identify the broadcast information of the successful association request through the pre-stored relevant information of the mobile device; the remaining fixed devices refer to fixed devices that have not established an over-connection with the mobile device through BLE, among several fixed devices that identify successful association request broadcasts. In addition, in the process that the mobile device traverses the fixed devices by taking n fixed devices as a basic unit, the number of a plurality of fixed devices does not change, but the number of the remaining fixed devices is gradually reduced by taking n as a basic unit and is finally 0. That is, the mobile device eventually establishes an over-connection with all of the fixed devices through BLE.
At this point, the mobile device records the relevant information and rssi of all the fixed devices in the fixed devices, and sorts the rssi according to the descending order to determine the strongest rssi in the fixed devices.
After the strongest rssi of the plurality of fixed devices is determined, the mobile device determines the relevant information of the fixed device corresponding to the strongest rssi of the plurality of fixed devices according to the recorded relevant information of the plurality of fixed devices, and establishes a connection relation with the fixed device corresponding to the strongest rssi of the plurality of fixed devices, thereby completing the communication process.
Mode 2: and traversing a plurality of fixed devices by taking n-1 fixed devices as a basic unit.
In an embodiment of the application, after the mobile device records the relevant information and the rssi of the n fixed devices connected with the mobile device and determines the strongest rssi of the n fixed devices connected with the mobile device according to a preset rule, the mobile device only keeps the connection between the fixed devices corresponding to the strongest rssi of the n fixed devices connected with the mobile device, and disconnects the connection between the remaining n-1 fixed devices of the n fixed devices connected with the mobile device.
Further, the mobile device establishes connection with n-1 fixed devices in the remaining fixed devices, and records relevant information and rssi of the reconnected n-1 fixed devices.
Further, the mobile device determines the strongest rssi of the currently connected n fixed devices and only maintains the connection with the fixed device corresponding to the strongest rssi of the currently connected n fixed devices, disconnecting the remaining n-1 fixed devices.
Further, the mobile device determines the relevant information of the remaining fixed devices again until all of the fixed devices establish an over-connection relationship with the mobile device through BLE.
So far, the mobile device only keeps the connection relationship with one fixed device, and the currently connected fixed device is the fixed device corresponding to the strongest rssi in the fixed devices.
It will be apparent to those skilled in the art that both of these approaches can enable the mobile device to establish a connection with the fixed device corresponding to the strongest rssi. The two modes differ in that mode 1 has n fixtures as a basic unit. Namely, n fixed devices are connected each time, after relevant information and rssi of the currently connected n fixed devices are recorded, all the fixed devices are disconnected, and the n fixed devices which are not connected before are reconnected. Finally, the related information and the rssi of all the fixed devices in the plurality of fixed devices are recorded, then the strongest rssi is determined, and finally the connection with the fixed device corresponding to the strongest rssi is reestablished. And the mode 2 is that n-1 fixed devices are used as basic units, the mobile device always keeps the connection with the fixed device corresponding to the strongest rssi among the currently connected n fixed devices, the n-1 fixed devices in the rest fixed devices are connected each time, finally, all the fixed devices in the fixed devices are established with connection, and finally, one fixed device is kept to be connected, namely, the fixed device corresponding to the strongest rssi in the fixed devices.
In one embodiment of the present application, if the mobile device moves in position during a communication, the strongest rssi value of several fixed devices may also change.
In an embodiment of the present application, when the variation value of the strongest rssi is lower than the first preset threshold, or the variation value of the strongest rssi is 0, it indicates that the location movement range of the mobile device is small, and the BLE connection relationship between the mobile device and the fixed device corresponding to the strongest rssi is not affected, and at this time, the mobile device continues to maintain the connection between the fixed devices corresponding to the strongest rssi.
In another embodiment of the present application, if the variation value of the strongest rssi is greater than the first preset threshold, or the variation value of the strongest rssi is equal to the first preset threshold, it indicates that the location movement range of the mobile device is large, and the BLE connection relationship between the mobile device and the fixed device is affected. At this point, the mobile device disconnects the fixed device corresponding to the strongest rssi and re-issues an association request broadcast with the fixed device.
Fig. 3 is a schematic diagram of an association process between a mobile device and a fixed device according to an embodiment of the present application.
As shown in fig. 3, the mobile device sends an association request broadcast to the fixed devices 1, 2, and 3. The association request broadcast comprises the relevant information of the mobile equipment, so that the fixed equipment can authenticate the mobile equipment through the prestored relevant information of the mobile equipment, and identify whether the mobile equipment and the fixed equipment belong to the same wireless communication system or belong to the same manufacturer.
After the fixed devices 1, 2 and 3 receive the association request broadcast and the related information of the mobile device is successfully identified, connection is established with the mobile device through BLE, and then the related information of the fixed device is sent to the mobile device. The information related to the fixed device is used for enabling the mobile device to determine whether the fixed device and the mobile device establish an over-connection through BLE through the information related to the fixed device.
And, the mobile device records the rssi of fixed device 1, the rssi of fixed device 2, and the rssi of fixed device 3, and then determines the strongest rssi. As can be seen from fig. 3, the fixed device corresponding to the strongest rssi is the fixed device 3.
Finally, the mobile device disconnects from the fixed devices 1 and 2, and only the connection relation with the fixed device 3 is reserved.
Based on the same inventive concept, the embodiment of the present application further provides a BLE-based adaptive association networking device, and an internal structure of the BLE-based adaptive association networking device is shown in fig. 4.
