The present invention discloses an intelligent operation and maintenance communication method based on the
JSON format, which aims to solve the problems of
high complexity, low security and difficulty in
scalability of existing protocols, thereby improving the reliability, speed and security of
smart grid operation and maintenance. Its characteristics are as follows: the communication protocol between the master and substation of the intelligent operation and
maintenance system is based on the publish / subscribe mechanism of the
MQTT protocol, and adopts the lightweight
JSON format for
data exchange, which is suitable for data communication between the intelligent operation and maintenance
master station and the intelligent operation and maintenance substation; the identity between the master and substation is verified by SSL / TLS
digital signature to ensure communication security; the
protocol design includes management channels and business channels, which are used to transmit management data and
business data of model services and asset services respectively, thereby improving the flexibility of
data management; the master and substation
integrated design concept is adopted to realize
configuration management and
data synchronization, so that the
master station can monitor and manage substations distributed in different locations in real time, thereby improving the operation and maintenance efficiency and response speed of the entire
system.
