The invention discloses an electric transmission line monitoring communication system based on a super-distance wireless optical network. The system comprises a wireless private network communication sub-network or a wireless private network and optical fiber mixed communication sub-network, a super-distance optical fiber communication backbone network, a monitoring primary station and a system network manager. The super-distance wireless optical network is characterized in that the wireless private network and optical fiber mixed communication sub-network wirelessly converges monitoring nodes of a plurality of nearby towers in a transmission line, an OPGW (optical fiber composite overhead ground wire) optical fiber communication system realizes uplink of the multiple nodes wirelessly converged, the optical fiber convergence nodes are connected to a transformer substation through an ADSS (all-dielectric self-supporting optic fiber cable), the wireless communication sub-network converges nodes of a plurality of nearby towers from node to multiple nodes, convergence signals are transmitted to the transformer substation by a wireless node-to-node manner, and data transmission between the transformer substation and a power company headquarter is performed through the existing data networks.

The invention discloses a Bluetooth BLE4.0 based infinite networking system. The system is used to form a cluster tree network; the cluster tree network comprises multiple cluster tree nodes; and each cluster tree node comprises a storage module, a sending module, a reception module, a verification module and a connection module, wherein the storage module stores the network characteristic number and information, the sending module sends and broadcasts the network characteristic number and information of the cluster tree node, the reception module receives the characteristic number and information from nodes in the same cluster tree network, the verification module verifies whether the network characteristic number received by the reception module is consistent with that of the node itself, and the cluster tree nodes of the same network characteristic number in the same cluster tree network are successively connected to form the network with the multiple nodes. The cluster tree network can support data interaction of low speed, low data bulk and low power consumption, and the method optimizes network management, simplifies the networking process and is high in networking speed.

The invention discloses a system and a method for improving LoRa network throughput. The system comprises an STM32 controller, a battery connected with the STM32 controller, a LoRa module connected with the STM32 controller, a LoRa gateway connected with the LoRa module, and an upper computer connected with the LoRa gateway. The upper computer provides time service for the terminal nodes through the LoRa gateway, and the STM32 controller uses the timer and the real-time clock to solve the problem of time synchronization of multiple nodes according to the current time.
