Problems solved by technology

But at present, when accessing the network server or application server based on LORA, the session key between the meter terminal and the network server or application server is fixed. In such a long-term situation, the session key is easy to be cracked, which is not conducive to the meter terminal. Secure communication between terminal and web server or application server

Abstract

The invention discloses a data communication method used in a LORA electric power centralized reading system. At the current moment, the data communication between the electric meter terminal and the target server is performed through the initial session key. From the generation time of the initial session key to When the time interval at the current moment satisfies the update period, the initial session key can be updated according to a predefined rule to obtain an updated session key, and then the updated session key is used to realize data communication between the meter terminal and the target server. By setting the update period, the session key for data communication between the meter terminal and the target server in the LORA electric power centralized reading system is updated, so as to avoid the long-term fixed session key between the meter terminal and the target server, and ensure the connection between the meter terminal and the target server. Secure communication between web servers or application servers. In addition, the present invention also discloses a data communication device, equipment and system for the LORA electric power centralized reading system, and the effect is as above.

Description

technical field [0001] The present invention relates to the field of electric power centralized reading system, in particular to a data communication method, device, equipment and system for the LORA electric power centralized reading system. Background technique [0002] The traditional meter reading technology of smart meters is divided into two categories: wireless meter reading technology and mobile cellular network meter reading technology. For wireless meter reading technology, its coverage is limited, its anti-interference ability is insufficient, and its receiving sensitivity is low, so it cannot be used for a long time. For the mobile cellular network meter reading technology, the mobile 4G IoT terminal needs to charge additional data fees, and the cost is relatively high. The ultra-long-range data communication technology (LORA) is a new technology based on the following 1GHZ. It is a technology dedicated to radio modulation and demodulation based on unlicensed sp...
