Each user is equipped with an RFID radio frequency identification card for carrying and storing information such as identity, each At least one CNC manager is available in the office or in each home (multiple rooms can be set up with multiple CNC controls) , each CNC manager can determine the number of user cards in its room or home (by the number of users) Consistent) and related information, the RFID radio frequency identification card periodically transmits the RF signal modulated by the encoded data, the number The control manager reads the radio frequency identification card signal through the RFID radio frequency identification internal card, and judges by the CPUI of the numerical control manager Confirm whether it is the user of this room, and then make corresponding control. The system timing workflow is divided into the following two cases:

(1) If the CNC manager is set for a period of time (the length of time can be set by the user according to the user's needs) After reading the transmission signal of the RFID radio frequency identification card carried by the user in the room, it is determined that no one in the room passes the electricity.

In addition to using the Internet of Things technology to automatically judge that there is no one in the room, the present invention can also adopt the following two working modes. Control of heating boilers, central air conditioning system end equipment (ie electric or solenoid valves, heat exchangers and end fans) The working condition: First, call the CNC controller to open the heating boiler and the central air conditioning system terminal equipment in advance. The second is to start the user's preset timing on mode by the numerical control manager. Both modes of work are unmanned In the case of the case, the terminal heating and cooling are started in advance.

By using the invention, the user only needs to carry the RFID radio frequency identification card with him, and not only automatically closes when the user leaves Closed heating boilers, central air conditioning system end equipment (or keep it in a state of heat preservation), and can also collect heating in real time The working condition of each end equipment of the boiler and central air conditioning system and the temperature of each room, as well as the heating boiler or central air Adjust the total return pipe and total outlet pipe temperature values of the system mainframe, and calculate the required boiler combustion intensity or central Air conditioning system main engine operating conditions, fan speed and pump head flow, and through the boiler control system, or to the air Adjust the host controller to send control commands, and at the same time control the frequency converter to control the frequency conversion of the fan and the water pump.
