The invention belongs to the field of
transformer substation monitoring, and provides a CMS
encryption remote control communication method and device based on a
transformer substation
monitoring system. The CMS
encryption remote control communication method based on the
transformer substation
monitoring system comprises the following steps: setting an
encryption transmission mode at each of a CMS
server and a CMS
client, and loading a corresponding
database for configuration; the CMS
client side judges whether connection with a CMS
server side port is established or not, and if yes, a
remote control command is issued to the CMS
server side; monitoring a TCP / IP (
Transmission Control Protocol /
Internet Protocol) port at the CMS server to judge whether a
remote control command is received or not, if so, continuing to judge a
positive response, if so, signing a remote control message, putting the signature content into a remote control structure body, coding the remote control message, sending the message, and forwarding a remote control success response to the CMS
client; after the CMS client receives the remote control response, the remote control message is subjected to signature
verification, whether signature
verification is passed or not is judged, if yes, remote control succeeds, and if not, remote control fails.
