Abstract

The invention relates to a remote detect central air conditioner and relative group control method, wherein said air conditioner comprises superior machine and low machine; the superior machine is one computer connected to photoelectric separate converter; the low machine at least comprises one machine group, with one communication module, one outdoor machine, and several indoor machines. The communication module can collect and transmit the data of indoor machines to the superior machine; the superior machine and the indoor machines are communicated with communication module. The user can use superior machine to detect low machine remotely.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to the field of remote operation of central air conditioners. Background technique [0002] With the widespread adoption of central air-conditioning in residential and commercial buildings. At present, the number of central air-conditioning units is increasing day by day, the distribution of each unit in the building is relatively scattered, the network structure is becoming more and more complex, and the user's control of the air-conditioning is also becoming more and more complicated. With the rapid development of computer hardware and software technology, remote monitoring of the operating status of central air-conditioning units by computer has been realized. However, the original remote monitoring mode is generally grouped by unit, that is, all indoor units corresponding to an outdoor unit form a group, and commands are issued to all indoor units in the group at the same time. ...
