[0011] Using the intelligent control system of the conference room can not only improve the work efficiency of the meeting and reduce the manual operation errors of the equipment, but also greatly enhance the experience of the meeting participants. In addition, the purpose of energy saving and emission reduction can be achieved through intelligent environmental control. With the advancement of technology, the intelligent control system of the conference room will become more efficient, intelligent and personalized.

[0012] The invention patent with patent application number 202310015188.6 discloses a conference room energy-saving system based on IoT intelligent power distribution and control. The system measures the total power consumption of the conference room in real time and collects it periodically; when the authorized administrator or participant enters by scanning the face and opening the door, the infrared sensor is triggered, and the system automatically supplies power to the conference equipment and turns on the lights, curtains and air conditioners. Conversely, when the infrared sensor detects that all personnel have left the conference room, the system delays 2 minutes to cut off the power supply of the conference equipment, and turns off the lights, electric curtains and air conditioning equipment. Combined with the conference room temperature collected by the temperature sensor, the air conditioning temperature is automatically set up or down to the energy-saving temperature target value, so that the conference room temperature is constant at the energy-saving temperature target value.

[0169] Output unit: includes relays and other interfaces, responsible for executing control instructions, such as turning on or off the devices connected to the controller.

[0170] Relay: When its coil is energized, its internal contacts change state (open or closed), thus controlling a load.

[0171] When the relay controller is working, the sensor or command sends a signal to the input unit, the processing unit analyzes these signals and decides whether to activate the relay coil according to the logic. The change of state of the relay contact (open or closed) controls the device connected to the output unit.

[0172] Application Cases

[0173] Home automation: control lighting, air conditioning, security systems, etc.

[0174] Industrial automation: control motor start and stop, valve switch, alarm system, etc.

[0175] Building automation: can be used for lighting, security door control, etc. in buildings.

[0176] Agricultural automation: used to control irrigation systems, greenhouse environment control, etc.

[0177] Laboratory and Education: used for control of experimental equipment, educational demonstrations, etc.

[0178] The selection and application of relay controllers depends on the control requirements, the type and size of electrical loads, and the control environment. Among them, programmable relay controllers (PLCs) are an advanced form of relay controllers that support complex control logic and network connections and are widely used in industrial and high-end automation applications.

[0179] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
