Embodiment Construction

[0009] Referring to Fig. 2, a central air-conditioning controller for radio-frequency wireless data communication, on the basis of the original air-conditioning outdoor controller, indoor controller, and wired controller, adds a radio-frequency wireless transceiver system and an address setting function circuit. The radio frequency wireless transceiver circuit can be composed of core chips such as nRF905 launched by Nordic VLSI company in Norway; it can work in 3 ISM channels of 433 / 868 / 915 MHz for free, and the address setting can be set by two sets of 8-bit parallel input and serial output Shift register implementation (such as 74LS165), on the parallel input side, D0-D7 is connected to GND with a dial switch to form a 16-bit address of A0-A15, a total of 65536 addresses can be selected, which can ensure that in the same residential area, no The same address system will exist. When installing and debugging on site, in the same residential area, set different bits of the DIP ...

Abstract

The invention relates to a central air conditioner controller using radio frequency wireless data communication to mainly solve the problem that regarding to various types of central air conditioning systems, such as water-circulation multi-couple unit air conditioning system and air-cooling multi-couple unit air conditioning system, when the complete machine is arranged outdoor and the terminal is arranged at different positions in the room, the wire data communication has problems of high cost, large arrangement difficulty, and poor stability and reliability. A central air conditioner controller using radio frequency wireless data communication comprises a plurality of outdoor controllers, indoor machines and wire controllers, wherein the outdoor controllers, indoor machines and wire controllers are communicated. The invention is characterized in that the outdoor controllers, indoor machines and wire controllers are communicated by radio frequency wireless transceivers. The micro computers (MCUs) of the mainboards of the outdoor controllers, indoor machines and wire controllers are both connected with an address setting circuit. The address setting selection function is added, the data of communication between the outdoor controllers and indoor machines and between the indoor machines and wire controllers has bits with different length. The outdoor controllers transmit data, the indoor machines and auxiliary machines receive data, so that the communication for each controller and machine pair is exclusive. The invention is mainly used for data communication among outdoor controllers, indoor machines and wire controllers.

Description

Technical field: [0001] The invention relates to a multi-connected one-drag-multiple controller of a central air conditioner. In particular, it relates to a central air-conditioning controller and communication setting method for radio frequency wireless data communication, which is mainly used for data communication of multi-connected one-to-multi-controllers of air conditioners, that is, between outdoor parallel hosts, between hosts and terminals, and between terminals and terminals Data communication between the terminal, the wire controller (that is, the wired controller) or the remote control. Background technique: [0002] With the continuous change of market demand, air conditioner manufacturers also need to continuously introduce various models and styles of air conditioners, especially commercial and residential central air conditioners (such as air-cooled cold air air conditioning systems, air-cooled cold water air conditioning Air conditioning systems, etc.) have...
