In table 1, Compatibility content is used to identify whether the protocol version numbers are compatible, 0x00 indicates version incompatibility, and 0x01 indicates version Compatibility;
the Connection content is used for identifying whether the protocol docking is completed, 0x00 indicates that the protocol docking is in the process of authentication, and 0x01 indicates that the protocol docking is completed;
referring to fig. 1, the specific process of controller authentication and protocol docking includes:
1) after the Tcp Connection is established, the controller sends a first heartbeat request to the IBMS, at the moment, the OUI is an initial value, Version content is 0x00, Compatibility value is 0x01, Connection value is 0x00, namely v0.0, Payload content comprises a controller serial number and a password, wherein the first 8 characters are serial numbers, the last 9 characters are passwords, and the Length value is the Length of an actual message.
2) After receiving a first heartbeat request of the controller, the IBMS detects a serial number and a password of the controller:
if the controller serial number and password are registered in the server, the OUI is changed to the OUI of the IBMS, and Version is changed to the highest Version number supported by the IBMS, such as: 0x2a, namely v2.10, the Compatibility value and the Connection value are unchanged, Payload content is empty, the Length value is the Length of an actual message, and the IBMS sends a first heartbeat response to the controller;
if the controller serial number and password are not registered in the server, the IBMS does not send the first heartbeat response to the controller any more.
3) After receiving the first heartbeat response of the IBMS, the controller checks Version content in the message and sends a second heartbeat request to the IBMS:
if the highest protocol Version number supported by the controller is compatible with the protocol Version number in the first heartbeat response message, the value of a Version field is unchanged, the Compatibility value and the Connection value are unchanged, Payload content is temporarily not specifically defined, and the Length value is the Length of the actual message;
if the highest protocol Version number supported by the controller is not compatible with the protocol Version number in the first heartbeat response message, the value of the Version field fills the highest Version supported by the controller, the Compatibility value is changed to 0x00, the incompatibility is shown, the Connection value is 0x00, Payload content is temporarily not specifically defined, and the Length value is the Length of the actual message.
4) After receiving the second heartbeat request of the controller, the IBMS checks Compatibility content and sends a second heartbeat response to the controller:
if the Compatibility value is 1, the value of the Compatibility field is unchanged, the Connection value is changed to 0x01, the controller authentication and protocol docking process is completed, Payload content is temporarily not specifically defined, and the Length value is the Length of an actual message; comparison Compatibility;
if the Compatibility value is 0, the alert contents are incremented, indicating that the versions do not match.
And step 3: transmitting protocol messages, and after an intelligent integrated system (IBMS) is authenticated and matched with a controller terminal, transmitting the protocol messages; the protocol message transmission comprises a configuration operation request and response, and an information acquisition operation request and response.
The operation type, in this embodiment, is specifically as shown in table 2 below, and when the operation type in the message sent by the IBMS backend management platform to the controller is Set Request, the operation type is used for the IBMS backend management platform to configure the controller, and the operation type in the message that the controller responds to the IBMS backend management platform is Set Response, which is used for the controller to return a configuration operation result to the IBMS backend management platform;
when the operation type in the message sent to the controller by the IBMS rear-end management platform is Get Request, the IBMS rear-end management platform is used for obtaining information from the green bus, and the operation type in the message responded to the IBMS rear-end management platform by the controller is Get Response, and the controller is used for returning the operation result of obtaining the information to the IBMS rear-end management platform.
The operation types Set Request and Get Request are provided with timing instructions for limiting Response time, and specifically, after a Set/Get Request message is successfully sent, if a corresponding Set/Get Response is not received within two seconds, the Response message is discarded. After the operation is repeated for three times, the corresponding response message is not received according to the requirement, and the server side generates an alarm.
The above operation types can be added with other types according to requirements, such as Software Download for online Software upgrading operation and Alarm for Alarm.
