Abstract
The utility model discloses a central air-conditioner temperature collection and control system based on Modbus protocols. The central air-conditioner temperature collection and control system comprises a PC (Personal Computer) system control terminal in which central air-conditioner temperature collection and control system software is set up; and the central air-conditioner temperature collection and control system is characterized by also comprising system collection terminals, wherein each system collection terminal comprises a temperature sensor, an MCU (Microprogrammed Control Unit) master control unit, an LCD ( liquid Crystal Display), a communication module, a storage module and a fan coil controller, and data transmission is carried out between the system collection terminals based on the Modbus protocols through RS485 interfaces of the communication modules. The central air-conditioner temperature collection and control system not only solves the problem that a conventional central air-conditioner for buildings has high energy consumption and a poor energy saving effect, but also solves the problem that as centralized collection and control cannot be realized due to different environments of conventional buildings, human cost is high.
