Operation control method and device, air conditioner and computer storage medium

The invention provides an operation control method and device, an air conditioner and a computer storage medium. The operation control method comprises the steps: controlling a narrowband communication assembly to build connection with a server, so as to send a successfully verified equipment serial number to the server; acquiring equipment identity information sent by the server, wherein the equipment identity information is generated by the server according to the equipment serial number; and generating a login request instruction and sending the login request information to the server, executing key negotiation and encryption processing to establish a private encrypted communication channel, wherein the login request carries equipment identity information of the air conditioner. By means of the technical scheme, the connection efficiency of the remote control air conditioner is improved, the steps of connection operation are simplified, and meanwhile the encryption performance and reliability of the remote
