In one embodiment of this embodiment, selecting an access concentrator of the target device among the plurality of concentrators according to the signal strength value includes: selecting a target concentrator with the maximum signal strength value from the plurality of concentrators; and determining the target concentrator as an access concentrator of the target device.
By selecting the target concentrator with the maximum signal intensity value as the access concentrator of the target equipment, the communication stability between the target equipment and the concentrator is improved. In some examples, a plurality of concentrator sets meeting communication conditions (for example, the signal strength value is greater than a preset threshold value) may also be selected based on the signal strength value, and then a concentrator with the least mounted devices is selected from the concentrator sets as an access concentrator of the target device, so as to implement load balancing and reduce communication pressure of the concentrator on the premise of ensuring communication stability.
In an implementation manner of this embodiment, after selecting the access concentrator of the target device among the plurality of concentrators according to the signal strength value, the method further includes: and sending a first control instruction to the access concentrator, wherein the first control instruction is used for instructing the access concentrator to send an address configuration frame to the target device, and the address configuration frame carries the device identifier of the access concentrator.
Because the issued address configuration frame has the device identifier such as the concentrator number, the newly-accessed network device (target device) can be accessed to the concentrator after being received, and the currently-accessed concentrator can be searched subsequently through the device identifier or addressing communication can be carried out.
In an implementation manner of this embodiment, after sending the first control instruction to the access concentrator, the method further includes: generating a node frequency change frame according to the channel value of the access concentrator, wherein the node frequency change frame carries the channel value of the access concentrator; and sending the node frequency change frame to the access concentrator so that the access concentrator forwards the node frequency change frame to the target equipment.
The server puts the value of the frequency change frame of the concentrator into the frequency change frame of the node according to the concentrator currently mounted by the target equipment, sends the frequency change frame to the wireless module 1 of the concentrator, and sends the frequency change frame to the wireless module 2 of the target equipment through the wireless module 1 and a debugging channel. And after receiving the node frequency change frame, the wireless module 2 modifies the channel thereof. The node frequency change frame is used for modifying the channel of the wireless module 2, and the wireless module 1 is switched to the working channel after sending the node frequency change frame. The channel value of the concentrator is the value of the frequency-changing frame of the concentrator, and is the channel value of the wireless module 1 sent to the concentrator by the server. The channel value in the node frequency-changing frame is consistent with the value of the concentrator frequency-changing frame, so that the two devices can communicate with each other after the target device successfully accesses the network.
In an implementation manner of this embodiment, after sending the node change frame to the access concentrator, the method further includes: issuing a second signal strength test frame to the access concentrator so that the access concentrator forwards the second signal strength test frame to the target equipment in a working channel and receives a signal test value replied by the target equipment based on the second signal strength test frame; and after receiving the signal test value uploaded by the access concentrator, sending a state inquiry frame to the access concentrator so that the access concentrator inquires the state data of the target equipment.

Optionally, before issuing the first signal strength test frame to the plurality of concentrators of the network, the method further includes: and switching the plurality of concentrators from the working signal to a debugging channel, switching other concentrators except the access concentrator back to the working channel after selecting the access concentrator of the target equipment, and switching the access concentrator back to the working channel after determining that the target equipment is normally accessed and debugs successfully. In some examples, in addition to switching channels, the concentrator and the target device may perform time division or frequency division communication, and access debugging of the target device and normal communication tasks of the accessed device are performed simultaneously on two channels, respectively.
In a specific implementation scenario of this embodiment, based on fig. 3, the working channels of the wireless modules of each concentrator are different, so as to achieve independent operations without affecting each other. The wireless module 1 executes a dual-channel working mode, and debugs channel transmission: a first signal strength test frame, an address configuration frame and a node frequency change frame; and (3) working channel transmission: a second signal strength test frame, a status query frame. The device networking process comprises the following steps:

s32: the server issues a first signal strength test frame, all wireless modules 1 in the system are switched to a debugging channel, and the first signal strength test frame is issued to newly-accessed monitoring equipment;
s33: after receiving the signal intensity value, the wireless module 2 on the newly-accessed monitoring equipment replies the signal intensity value, and all the wireless modules 1 receive the signal intensity value at the moment;
s34: all concentrators report the received signal strength value to a server, and the server judges which concentrator uploads a large signal strength value;
s35: the server appoints the concentrator with large signal intensity value to send an address configuration frame in a debugging channel, and controls other concentrators to switch to a working channel to continue normal work, and at the moment, the concentrator preference stage is completed;
the issued address configuration frame is provided with equipment identifiers such as a concentrator number and the like, so that the newly-accessed equipment belongs to the concentrator after being received;
s36: then the server sends the node frequency change frame (with the working channel value) to the wireless module 2 according to the value of the frequency change frame of the concentrator, and modifies the wireless module 2 into a working channel;
s37: at the moment, the wireless module 1 is automatically switched to a working channel, and a second signal strength test frame is issued to test whether the frequency change frame of the node is successful or not;
s38: after the second signal strength test frame is replied, the server sends a state query frame, directly queries the state data of the newly-accessed network equipment in the working channel, and if the state data is queried, the network access of the equipment is successful.
By adopting the scheme of the embodiment, when the equipment mounted under the concentrator is connected to the network, the concentrator which normally runs does not need to be powered down, and the matched concentrator can automatically select whether the equipment newly connected to the network is mounted under the equipment name. Meanwhile, the network access debugging of the equipment is conveniently carried out on site, other concentrators which are electrified and normally run are not needed to be disconnected, the newly-networked equipment can be selected to the concentrator with the strongest signals around, and the network access success rate of the equipment and the success rate of subsequent control and information uploading are improved.
