Embodiment 1
[0026] figure 1 is an architecture diagram of a building management system according to an embodiment of the present invention, such as figure 1 As shown, the whole system is divided into four layers: the device layer, the analysis layer, the configuration layer, and the interaction layer.
[0027] The equipment layer is used to manage the equipment connected to the building management system and realize the binding of the communication protocol with the equipment;
[0028] Specifically, the device layer includes a docking protocol frame, a status frame, a fault / alarm frame, a control frame, and an interaction module frame. The site needs hardware equipment connected to the building management system. The equipment communication protocol includes broadcast frames that need to be recognized by the building management system, protocol frames that can be converted by the building management system, and template frames that can automatically create an interactive interface.

Embodiment 2
[0036] figure 2 is a flowchart of a method for automatic device binding according to an embodiment of the present invention, such as figure 2 As shown, the method includes the following steps:
[0037] Step S201, between the building management system and the device newly connected to the network, automatically completes the protocol binding by binding the protocol frame and the standard protocol frame;
[0038] Step S202, in the case that the device includes the interactive template frame, the building management system receives the interactive template frame sent by the device, and assembles the interactive interface according to the interactive template frame;
[0039] Step S203, the building management system notifies the device to send all communication frames normally.
[0040] For the specific implementation of the above step S101, this embodiment provides a preferred implementation, that is, the building management system receives the broadcast frame sent by the de...
Embodiment 3
[0046] image 3 is the operation flow chart of the building management system according to the embodiment of the present invention, such as image 3 shown, the process includes:
[0047] 1) When a new hardware device is connected to the network, the hardware device needs to write a program according to the broadcast frame defined in advance by the same building management system.
[0048] 2) When the building management system receives the broadcast frame of the hardware device, it continues to initiate the request information of the binding protocol frame to the hardware device.
[0049] 3) The hardware device initiates the binding protocol frame (that is, the communication frame containing the binding protocol), and the building management system maps the binding protocol frame in the hardware device according to its own compatible standard frame structure, and maps the binding protocol frame to the Analyze and compare with the standard protocol frame, and finally encapsul...
