The invention relates to a pressure plate
data acquisition module based on trusted WLAN (
Wireless Local Area Network)
network security authentication, which comprises a secret key and
certificate generation unit, a secret key and
certificate management unit and a pressure plate
data acquisition unit, the
intranet secret key
certificate server is responsible for issuing, verifying and managing equipment, certificates and secret keys used in the
intranet; the trusted pressure plate
data acquisition module provides an equipment
MAC address for the secret key certificate generation unit, when equipment enters a debugging stage after being installed in a
transformer substation, a
transformer substation trusted WLAN network starts a temporary network, an
intranet secret key
certificate server is started, and the intranet secret key
certificate server applies for replacing a formal secret key or certificate; after the application, a formal secret key and a formal certificate are automatically distributed to the equipment after comparison and auditing to an intranet secret key
certificate server are completed. According to the invention, the
network security is improved to a great extent, the
transformer substation pressing plate acquires the secret key certificate of the network to realize automatic management, and the security requirement of state grid intelligent development is further improved.
