Description

Technical Field

[0001] The utility model relates to the field of building control, in particular to a dual-network-port building controller. Background Art

[0002] In modern building management systems, building controllers play a vital role. They are responsible for integrating and controlling various systems in the building, such as lighting, security, air conditioning and communication services. With the development of intelligent building technology, the functions of building controllers have also expanded from simple monitoring to comprehensive energy management and environmental monitoring to improve the energy efficiency of equipment in the building and ensure comfort and safety.

[0003] In related technologies, building controllers are usually equipped with a single network interface, which enables them to have network connection functions and access the local area network or the Internet through wired or wireless means, so that building managers can remotely monitor and control various systems in the building. This configuration can meet basic building management needs to a certain extent and support basic data collection and equipment control functions.

[0004] However, in the related technology, all data of the building controller is transmitted through the same network interface.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0037] The utility model provides a dual-network port building controller, such as Figure 1 , which is a module connection diagram of a dual-network-port building controller 1 in an embodiment of the utility model.

[0040] In this way, the utility model performs classified data interaction through two independent network interfaces, which not only ensures the quality of important management data, but also does not affect the real-time nature of field data, while also enhancing the remote transmission capability of management data, thereby achieving optimization and improvement of the building control system.

[0041] For ease of understanding, the following further describes the modules of the dual network port building controller 1 provided by this embodiment in combination with the above embodiments. Figure 2 , Figure 2 It is another module connection diagram of an embodiment of the utility model.

If the first network port 1011 or the second network port 1012 is disconnected, the corresponding red LED light can be lit to indicate that the network port is disconnected. If the network port connection is normal, the green LED can be lit to indicate that the network is normal.

[0056] In some embodiments, the dual-network-port building controller 1 further includes a central processor 105 and a buzzer 112 . The buzzer 112 is electrically connected to the central processor 105 and is used to receive an alarm instruction from the central processor 105 and to sound an alarm when a fault or abnormality occurs in the dual-network-port building controller 1 .

[0057] Specifically, the buzzer 112 can adopt an active buzzer 112 module connected to the GPIO interface of the controller.
