Full duplex central air conditioning control system based on power carrier communication
The utility model relates to a full duplex central air conditioning control system based on power carrier communication. The full duplex central air conditioning control system is provided with a control center and a plurality of terminal controllers with same structure, wherein the control center is in communication with the plurality of terminal controllers through a power line in a building, the control center is composed of a PC (Personal Computer) supervisor and a communication controller connected with the PC supervisor, and the communication controller is connected with the power line; and each terminal controller comprises a terminal power carrier module, a terminal CPU (Central Processing Unit) a temperature controller, an actuator as well as a first wind disc and a second wind disc which are connected in sequence, wherein the actuator is connected with the terminal CPU, and the first wind disc and the second wind disc are connected with the actuator respectively, the terminal CPU is also connected with a CPU watchdog timer, and the terminal power carrier modules are connected with the communication controllers through the power line. According to the utility model, due to adoption of a power carrier technology in the communication process, the communication network is the power line in the building without deploying a special communication terminal, and a great number of labor and material resources are saved. Because the bidirectional data transmission is adopted in the communication process, the control center displays various terminal states and temperature, so that the full duplex central air conditioning control system is more intuitive to operate and is convenient for integrated control.
