[0021] It should be noted that the embodiments in the invention and the features in the embodiments can be combined with each other if there is no conflict.

[0022] In the description of the invention, it should be understood that the terms "center", "vertical", "horizontal", "upper", "lower", "front", "rear", "left", "right", The orientation or positional relationship indicated by "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention The creation and simplification of the description does not indicate or imply that the pointed device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the invention. In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of these features. In the description of the invention, unless otherwise specified, the meaning of "multiple" means two or more.

[0023] In the description of the invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection or an optional connection. Detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication between two components. For those of ordinary skill in the art, the specific meaning of the above terms in the creation of the present invention can be understood through specific circumstances.

[0024] The invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0025] Such as figure 1 Said, a video monitoring system, including a monitoring center set in a monitoring room, video monitors, fire fighting systems, energy saving systems, air purification systems distributed in various rooms in the building, and the video monitor, fire fighting system , Energy-saving system, control terminal connected to air purification system, KNX bus;

[0026] The control terminal includes a processor, and an interface module, a wireless communication module, and a KNX bus transceiver module that are electrically connected to the processor through pins; the processor is a single-chip microcomputer, and the interface module, wireless communication module, and KNX bus transceiver are connected through pins. Module electrical connection;

[0027] The monitoring center includes a monitoring host and a server;

[0028] The control terminal is connected to the monitoring center through the KNX bus;

[0029] An electromagnetic shielding camera cover is provided on the video monitor.

[0030] The energy saving system includes infrared sensors, lighting lamps, air conditioners, and electric fans.

[0031] The air purification system includes a dust sensor, a carbon dioxide concentration sensor, and an air purifier.

[0032] The output communication interface of the server is respectively connected to the input communication interface of the control terminal of each controlled room through Ethernet or wireless communication.

[0033] The wireless communication module includes one of WIFI, ZigBee, 2G, 3G, and 4G networks.

[0034] The server is a cloud server.

[0035] It also includes a mobile phone client, which communicates with the monitoring center through a wireless network.

[0036] The working process of the invention is as follows: the invention uses the monitoring system distributed in each room to monitor the indoor situation in real time, and transmits it to the control device through the data line or wireless network. The control device transmits the data to the monitoring center through the KNX bus for data Storage and management; KNX provides power signals on the one hand and data transmission on the other, saving energy and reducing energy consumption;

[0037] The indoor smoke concentration is detected by the smoke detector in the fire fighting system. The smoke detector and alarm device are connected to the control device through a data line or wireless network. The control device transmits data to the monitoring center through the KNX bus for data storage and management; If the smoke concentration exceeds the preset range, an alarm will be used to alert people around;

[0038] The infrared sensor in the energy-saving system detects whether there are people in the room. The infrared sensor transmits data to the control device through a data line or wireless network. The controllers of lighting, air conditioner and electric fan are all connected to the control device through a data line or wireless network. The data is transmitted to the monitoring center through the KNX bus for data storage and management; when it is detected that there is no one in the room, the lights, air conditioners and electric fans are controlled to stop working to reduce energy consumption;

[0039] The air quality is detected by the dust sensor and carbon dioxide concentration sensor in the air purification system, and the data is transmitted to the control device through the data line or wireless network. The air purifier is connected to the control device through the data line or wireless network. When the single-chip microcomputer detects the air dust If the concentration or carbon dioxide concentration exceeds the preset range, the air purifier is controlled to provide a healthy working environment for users;

[0040] It also includes a mobile phone client, through which building managers can query the indoor environment in real time to facilitate timely handling of abnormalities.

[0041] The invention creates an electromagnetic shielding camera cover to suppress the interference of other equipment to the monitoring system and improve the anti-interference ability of the system.

[0042] The above are only the preferred embodiments created by the present invention, and are not intended to limit the creation of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in Within the scope of protection created by the present invention.
