Abstract

The invention discloses a data communication method for an LORA power centralized meter reading system. When data communication between an electricity meter terminal and a target server is performed at a current moment, the data communication is performed through an initial session key, when a time interval between a generation moment of the initial session key and the current moment satisfies anupdate period, the initial session key can be updated with a predefined rule to obtain an updated session key, and then, the data communication between the electricity meter terminal and the target server is implemented by the updated session key. The session key of the data communication between the electricity meter terminal and the target server in the LORA power centralized meter reading system is updated by setting the update period, so that the situation that the session key between the electricity meter terminal and the target server is unchanged for a long time, and the secure communication between the electricity meter terminal and a network server or an application server is guaranteed. In addition, the invention further discloses a data communication apparatus, device and systemfor the LORA power centralized meter reading system, which has the same effects mentioned 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...
