The LoRa networking adopts a star network, and 1 LoRa gateway is connected with a plurality of LoRa collection modules. There may be multiple LoRa gateways on site, distributing multiple LoRa networks, and the LoRa networking mode is described according to fig. 1.
Fig. 1 shows that 2 block terminals distribute in the power distribution room, and the loRa equipment in each block terminal constitutes mutually independent loRa network, and 1 loRa network 1 of block terminal comprises loRa gateway A and loRa collection module A1~ AN, and 2 loRa networks 2 of block terminal comprises loRa gateway B and loRa collection module B1~ BN, and different loRa networks work avoids mutual interference in different channels promptly.
The loRa gateway possesses 2 loRa modules, is loRa module a and loRa module b respectively, and wherein loRa module a is used for carrying out electric power parameter collection communication with loRa collection module, and loRa module b is used for the network deployment and receives the warning message that loRa collection module uploaded. The loRa modules a of the field LoRa gateways work in different channels, and the LoRa modules b of all the field LoRa gateways work in the same channel. The LoRa gateway is provided with a networking button, namely a LoRa module b starts a networking mode when the button is pressed; the default is the networking mode when leaving factory for the loRa collection module, and leaves factory the operating channel the same with loRa module b of loRa gateway to possess "reset button", loRa collection module resumes the networking mode when the button is pressed promptly.
For convenience of networking description, assuming that the LoRa module b and the LoRa acquisition module of the LoRa gateway are arranged on the channel 1, the LoRa gateway a and the LoRa acquisition modules a 1-AN are installed first during field engineering implementation, that is, the LoRa devices planned to be implemented on the same LoRa network in advance are installed. After the LoRa gateway A and the LoRa acquisition modules A1-AN are installed and powered on successfully, the LoRa module b is in a networking mode after the LoRa gateway A presses a networking button. The LoRa module a of the LoRa gateway a searches for an unused channel other than the channel 1, and if the channel 2 is not used, the operating frequency band of the LoRa module a is set in the channel 2. LoRa module b and the LoRa collection module of LoRa gateway A just carry out the network deployment and verify, after the LoRa collection module network deployment succeeds, LoRa module b sends the LoRa collection module of switching channel instruction to the LoRa network 1, and then LoRa collection module operating frequency switches to channel 2 to convert into operating mode from the network deployment mode, LoRa gateway A's LoRa module a alright carry out data acquisition communication with LoRa collection module. LoRa module b closes the network deployment mode when LoRa gateway A detects that the LoRa collection module that LoRa module b links to each other all is in operating mode, and LoRa module b only accepts the alarm information that LoRa collection module uploaded this moment.
After the implementation of the loRa equipment in the distribution box 1 is completed, the installation of the loRa equipment in the distribution box 2 can be carried out, and when the loRa equipment of the distribution box 2 is in a networking mode, the loRa equipment in the distribution box 1 can not be networked due to being in a working mode. And sequentially implementing different LoRa network construction on site according to the steps.
When having the loRa collection module to change or add on the scene, can press this loRa collection module's "reset button" and the loRa gateway's in the loRa network that will join "network deployment button", loRa collection module alright network deployment authentication join in the loRa network. If the old LoRa acquisition module is replaced, the LoRa gateway finds that the device is not online for 3 consecutive days under the power-on condition, and the device can be deleted from the device management library after being considered to be replaced.
The examples should not be construed as limiting the present invention, but any modifications made based on the spirit of the present invention should be within the scope of protection of the present invention.
