Some wireless network node configurations in the prior art have many drawbacks. For example, currently, online configurations are typically employed for the configuration of a large number of wireless network nodes, which is inefficient. For another example, in the configuration process of network nodes by wifi, because the broadcast range is larger, the number of nodes in the broadcast range is numerous, and there is a problem of identifying a large number of network nodes, it is difficult to configure a designated node, but the complexity of the technology is increased by using infrared technology or other auxiliary technology. Moreover, the distribution network communication distance is usually far, and because the distribution network process is in clear text transmission, the far distribution network communication distance easily enables the secret key to be intercepted, and further malicious invasion to the wireless network is easily caused. In addition, the installer needs to be familiar with the use of APP related to configuring network nodes, and the parameter configuration of wireless network nodes, and the existing complex network increases the technical requirements and training costs for the installer.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In order to solve the above technical problems, the embodiments of the present invention provide a method for configuring a wireless network node, where the method is applied to a wireless network configuration device with BLE (Bluetooth Low Energy ) function, where the wireless network configuration device may be a handheld terminal device or other mobile devices (such as a smart phone, a tablet computer, a smart watch, etc.). Fig. 1 shows a flow diagram of a method of configuring a wireless network node according to one embodiment of the invention. Referring to fig. 1, the method includes steps S102 to S106.
Step S102, limiting the communication range of the BLE function according to the preset parameters.
In this step, the preset parameter may be a communication range parameter that the wireless network configuration device communicates with using the BLE function. For example, if the preset parameter is 2 meters, the BLE communication range of the wireless network configuration device is set to be 2 meters by using the preset parameter, and at this time, the wireless network configuration device may communicate with each wireless network node device within the range of 2 meters. The BLE technology is a robust wireless technology with low cost, short distance and interoperability and works in unlicensed 2.4GHz ISM radio frequency band.
Step S104, the BLE function is started, and a configuration request is sent to each wireless network node device within the limited BLE communication range.
In this step, the wireless network node device may be a sensor or other devices requiring configuration parameters, for example, a sensor (such as a photoelectric sensor for controlling a lighting fixture), a wireless communication module installed inside the lighting fixture and used for remotely controlling the lighting fixture, and controlling on/off of the intelligent device, adjusting lighting brightness or color, and the like according to a control signal received by the wireless communication module. And, the wireless network node device also has a BLE function to realize communication with the wireless network configuration device with the BLE function.
Step S106, receiving a confirmation message returned by any wireless network node equipment aiming at the configuration request, and establishing BLE connection with the wireless network node equipment meeting the preset condition.
In this embodiment, the communication range of the BLE function is defined according to the preset parameter, for example, the communication range is defined within a reasonable small value range, so that after the wireless network configuration device starts the BLE function, information configuration can be performed on the designated wireless network node device within the defined communication range, so that the configuration of the wireless network node device is more targeted, and the problem of difficulty in identifying a large number of wireless network node devices is avoided. In addition, the embodiment of the invention simulates near field communication by utilizing BLE technology, thereby effectively avoiding the problem that the wireless network node equipment is maliciously intercepted and invaded in the information configuration process and improving the security of the wireless network node configuration.
Furthermore, the configuration mode of the wireless network node in the embodiment of the invention is simple and quick, thereby not only reducing the skill requirements of related technicians, but also effectively improving the working efficiency of the related technicians.
Referring to step S102, in an embodiment of the present invention, when the communication range of the BLE function is defined according to the preset parameters, the number of radio network node devices in the BLE communication range may be preset, and then an appropriate preset parameter is selected according to the set number of radio network node devices to define the communication range of the BLE function. For example, in order to enable the wireless network configuration device to connect with the wireless network node device more specifically within its communication range, the number of wireless network node devices within its BLE communication range may be set to be substantially kept between 1 and 2, and then, in combination with the distance between the devices, the preset parameter is determined to be 2 meters, that is, the BLE communication range of the wireless network configuration device is 2 meters. Of course, the BLE communication range of the wireless network configuration device may also be set to other values, such as 1 meter, 3 meters, 4 meters, etc., which is not limited in the embodiment of the present invention.
Referring to step S104 above, in an embodiment of the present invention, before the radio network configuration device performs data configuration on the radio network node device, it is required to start the BLE function, and then send a configuration request to each radio network node device within the limited BLE communication range. In this embodiment, the wireless network configuration device may send a configuration request to each wireless network node device within the BLE communication range defined above in the form of a configuration network request broadcast packet, where the configuration network request broadcast packet may carry address information of the wireless network configuration device, so that the wireless network node device that receives the configuration network request broadcast packet may subsequently use the address information to establish a connection with the wireless network configuration device.
Among them, a broadcast packet (broadcast packet) interface may be used to transmit broadcast packets to many networks supported by the system. Broadcast is commonly used for two reasons, firstly, an application (e.g. a program in a wireless network configuration device for configuring a wireless network node) wishes to find a resource in the local network without the application having any a priori knowledge of the address of the resource. Second, some important functions, such as routing, require that their information be sent to all found neighbors. In the embodiment of the invention, the wireless network configuration equipment transmits the network allocation request broadcast packet to each wireless network node equipment within the BLE communication range, so that the wireless network configuration equipment does not need to respectively transmit the configuration request for each wireless network node equipment, and the configuration time of the wireless network node equipment is effectively saved.
Referring to step S106 above, in an embodiment of the present invention, after the wireless network configuration device receives the acknowledgement message returned by any wireless network node device for the configuration request, the wireless network node device meeting the preset condition may be selected, and a BLE connection is established with the wireless network node device. If the wireless network configuration device receives the acknowledgement message returned by the at least two wireless network node devices, BLE connection needs to be established with the wireless network node devices meeting the preset rule.
In this embodiment, if the preset rule is the radio network node device with the shortest arrival time of the acknowledgement message. After receiving the acknowledgement messages returned by the at least two wireless network node devices, the wireless network configuration device may first determine the arrival time of the acknowledgement messages returned by the at least two wireless network node devices, then select the wireless network node device corresponding to the acknowledgement message with the shortest arrival time, and establish BLE connection with the wireless network node device. For example, if the wireless network configuration device receives the acknowledgement messages returned by the two wireless network node devices, and it is known by analysis that the time for the two wireless network node devices to return the acknowledgement messages is 2 seconds and 3 seconds, respectively, then the wireless network configuration device is connected with the wireless network node device that returns the acknowledgement messages for 2 seconds.
If the preset rule is the strongest radio network node device of the RSSI (Received Signal Strength Indication ) of the acknowledgement message. After receiving the acknowledgement messages returned by the at least two wireless network node devices, the wireless network configuration device may analyze the RSSI of the acknowledgement messages returned by the at least two wireless network node devices, and then select the wireless network node device corresponding to the acknowledgement message with the strongest RSSI, and establish BLE connection with the wireless network node device.
In this embodiment, after receiving the configuration request of the wireless network configuration device, the wireless network node device may return an acknowledgement message for the configuration request to the wireless network configuration device in the form of an APK packet (message acknowledgement packet), that is, the wireless network configuration device receives the APK packet sent by the wireless network node device, to acknowledge that the wireless network node device successfully receives the configuration request.
In an alternative embodiment of the present invention, after the BLE connection is established with the wireless network node device meeting the preset condition, a read-write operation request may also be sent to the wireless network node device that is successfully connected, so as to perform wireless network information configuration on the wireless network node device. The read-write operation request carries relevant configuration information of the wireless network node equipment. In this embodiment, the relevant configuration information of the wireless network node device may include a unique identifier (such as a unique number, unique geographical location information, etc.) of the wireless network node device, a configuration parameter of the wireless network node device, packet information to which the wireless network node device belongs, scene setting information of the wireless network node device, etc., and may of course also include other configuration information.
In this embodiment, before sending a read-write operation request to a successfully connected wireless network node device, the wireless network configuration device may generate a configuration file in advance, where the configuration file includes relevant configuration information of a plurality of wireless network node devices. When the wireless network configuration equipment is successfully connected with a certain wireless network node equipment, the unique identifier of the wireless network node equipment which is successfully connected is acquired. And then, extracting relevant configuration information of the wireless network node equipment corresponding to the unique identifier from the pre-generated configuration file according to the acquired unique identifier, and sending the relevant configuration information to the wireless network node equipment which is successfully connected, so that the wireless network node equipment is configured with wireless network information.
For example, before sending a read-write operation request to a successfully connected wireless network node device, the wireless network configuration device establishes a plurality of wireless network node devices and a plurality of virtual nodes corresponding to the wireless network node devices respectively, and pre-stores each virtual node and a detailed configuration scheme corresponding to each virtual node in the wireless network configuration device (such as a handheld terminal device) in a configuration file mode. When the information configuration is needed to be carried out on the wireless network node equipment, an installer only needs to search the virtual node corresponding to the wireless network node equipment to be configured from the configuration file according to the node position information of the wireless network node equipment to be configured, obtains the relevant configuration information of the virtual node, and sends the information to the wireless network node equipment by using BLE, so that the information configuration of the wireless network node equipment is realized, and the skill requirement on the installer can be greatly reduced by the information configuration mode.
In order to more clearly embody the schemes of the embodiments of the present invention, the present invention will be described in terms of embodiments in a specific scene. In this embodiment, the wireless network configuration device employs a handheld terminal device.
Firstly, setting the BLE communication range of the handheld terminal equipment to be 2 meters, then starting the BLE function of the handheld terminal equipment, and sending a distribution network request broadcast packet to each wireless network node equipment within the range of 2 meters, wherein the distribution network request broadcast packet contains address information of the handheld terminal equipment. Referring to fig. 2, three radio network node devices, namely, radio network node device 1, radio network node device 2 and radio network node device 3, are included in the communication range of 2 m BLE of the handheld terminal device, and correspond to node 1, node 2 and node 3 shown in fig. 2, respectively. At this time, as shown in fig. 3, the handheld terminal device simultaneously transmits a network allocation request broadcast packet to the wireless network node device of the node 1, the wireless network node device of the node 2, and the wireless network node device of the node 3.
After a certain delay, the wireless network node device of the node 2 sends an ACK packet (i.e. a message acknowledgement packet) to the handheld terminal device according to the address information of the handheld terminal device, i.e. confirms that the wireless network node device successfully receives the distribution network request broadcast packet. Since the handheld terminal device only receives the ACK packet returned by the radio network node device 2, the handheld terminal device establishes a BLE connection with the radio network node device 2.
When the connection between the handheld terminal device and the wireless network node device 2 is successful, the unique number, such as 001, of the wireless network node device 2 is obtained first, then the virtual node corresponding to the number 001 is searched from the pre-stored configuration file, and relevant configuration information related to the virtual node is obtained. For example, if the wireless network node device of the node 2 is a wireless sensor for controlling the lighting fixture, the handheld terminal device may acquire the sensor configuration parameter of the virtual node, and further carry the acquired sensor configuration parameter in the read-write operation request, and send the sensor configuration parameter to the wireless network node device of the node 2. After the wireless network node device of the node 2 receives the sensor configuration parameters, a response message is returned to the handheld terminal device, which indicates that the configuration of the configuration parameters sent at this time is successful.
Further, if the handheld terminal device needs to perform other information interaction with the wireless network node device of the node 2, other configuration parameters may be continuously sent to the wireless network node device of the node 2, for example, the wireless network node device of the node 2 is set to be a "conference scene" or the like, and similarly, after receiving the sensor configuration parameters, the wireless network node device of the node 2 still returns a response message to the handheld terminal device, which indicates that the configuration of the configuration parameters sent this time is successful.
Finally, after the configuration of the wireless network node device of the node 2 by the handheld terminal device is completed, and other wireless network node devices are not required to be configured, the BLE function on the handheld terminal device can be closed.
Based on the same inventive concept, the embodiment of the invention also provides a configuration device of the wireless network node, which is applied to wireless network configuration equipment with a BLE function, wherein the wireless network configuration equipment can be handheld terminal equipment or other mobile equipment. Fig. 4 shows a schematic structural diagram of a configuration apparatus of a wireless network node according to an embodiment of the present invention. Referring to fig. 4, a configuration apparatus 400 of a wireless network node includes a parameter qualifier 410, a request transmitter 420, and a connector 430.

and a connector 430, connected to the request transmitter 420, for receiving a confirmation message returned by any wireless network node device for the configuration request of the request transmitter 420, and establishing BLE connection with the wireless network node device meeting the preset condition.
In an embodiment of the present invention, the parameter definer 410 selects a corresponding preset parameter according to a preset number of wireless network node devices within the BLE communication range, and defines the communication range of the BLE function.
In an embodiment of the present invention, the request transmitter 420 sends a configuration request to each radio network node device within the limited BLE communication range in the form of a network allocation request broadcast packet, where the network allocation request broadcast packet carries address information of the radio network configuration device.
In an embodiment of the present invention, if the connector 430 receives only the acknowledgement message returned by one radio network node device, a BLE connection is established with the radio network node device, and if the connector 430 receives the acknowledgement message returned by at least two radio network node devices, a BLE connection is established with the radio network node device satisfying the preset rule.
In an embodiment of the present invention, if the connector 430 receives acknowledgement messages returned by at least two wireless network node devices, the arrival time of the acknowledgement messages returned by the at least two wireless network node devices is determined, and the wireless network node device corresponding to the acknowledgement message with the shortest arrival time is selected, and a BLE connection is established with the wireless network node device.
In another embodiment of the present invention, if the connector 430 receives the acknowledgement messages returned by the at least two radio network node devices, the RSSI of the acknowledgement messages returned by the at least two radio network node devices is analyzed, and the radio network node device corresponding to the acknowledgement message with the strongest RSSI is selected, and a BLE connection is established with the radio network node device.
The embodiment of the invention also provides another configuration device of the wireless network node, and the wireless network configuration device can be a handheld terminal device or other mobile devices.

Referring to fig. 5, a configuration apparatus 400 of a wireless network node includes a configurator 440, a generator 450, and a receiver 460 in addition to the above-described devices.
And the configurator 440 is connected with the connector 430, and after the connector 430 establishes BLE connection with the wireless network node equipment meeting the preset condition, the configurator sends a read-write operation request to the wireless network node equipment successfully connected by the connector 430, and carries out wireless network information configuration on the wireless network node equipment, wherein the read-write operation request carries relevant configuration information of the wireless network node equipment.
The relevant configuration information of the wireless network node equipment comprises a unique identifier of the wireless network node equipment, configuration parameters of the wireless network node equipment, grouping information of the wireless network node equipment, scene setting information of the wireless network node equipment and the like.
