Distribution automation is a concept proposed in the 70 th generation of western developed countries, and has been fully developed in japan, europe and the united states. Many attempts have been made in China, but the focus has been mainly on cities. The distribution automation organically integrates monitoring, protection, control and metering of a distribution network under normal and accident conditions with work management of power supply departments, improves power supply quality, establishes a closer and more responsible relationship with users, meets the diversity of user requirements at a reasonable price, and strives for the best power supply economy.
At present, most distribution network automation systems can also play the roles of monitoring the operation condition of a distribution network and remotely controlling to change the operation mode when the distribution network normally operates, and faults can be timely perceived, however, the distribution automation of the current power system mainly depends on a public network to carry out uplink transmission of telemetering data, and in a remote suburb, due to the fact that the network of the public network is poor and even does not have public network signals, the telemetering data of distribution automation cannot be uploaded to a main station, and the distribution automation terminal is in an unsupervised state, even if working information of a distribution line cannot be known.
For places without public networks or public network signal differences, three solutions are generally available, namely a wireless ad hoc network, a microwave station and an optical fiber. In the field of power dispatching, due to the high requirements on real-time performance, reliability and safety, microwave stations and optical fibers are generally adopted, but the two modes have high investment and high cost.

The wireless technologies forming the local area network mainly include 2.4GHz WiFi, Bluetooth, Zigbee and the like, and the wireless technologies forming the wide area network mainly include 2G/3G/4G and the like. The advantages and the disadvantages of the wireless technologies are obvious, and before a Low Power Wide Area Network (LPWAN) is generated, only one of long distance and Low power consumption seems to be selected; after adopting the LPWAN technology, designers can realize both the LPWAN technology and the LPWAN technology, realize longer-distance communication and lower power consumption to the maximum extent, and simultaneously save the cost of an additional repeater.
The LoRa is one of LPWAN communication technologies, and is an ultra-long-distance wireless transmission scheme based on spread spectrum technology adopted and popularized by Semtech corporation in the united states. The scheme changes the prior compromise consideration mode of transmission distance and power consumption, provides a simple system which can realize long distance, long battery life and large capacity for users, and further expands the sensing network. Currently, the LoRa mainly operates in global free frequency bands including 433, 868, 915 MHz, and the like.
