For example, if the connected sub-communication module 22 uses a 4G communication scheme in a project and the power supply box installation environment is a negative layer of a shopping mall, a middle of a metal ceiling and reinforced concrete or a top layer of a skyscraper, the 4G signal is weak, and normal data transmission cannot be realized by 4G communication. With reference to fig. 2, a Wifi communication scheme with high signal strength can be selected, the sub-communication module is switched to the sub-communication module 22 for Wifi communication, and under the condition of field accidental communication failure, the problem can be solved immediately by only replacing one sub-communication module 22, so that the communication modes of the terminal machine 2 and the host machine 1 can be switched at will no matter in the early stage, the middle stage or the after-sale stage of a project, rapid communication repair is realized, the field construction after-sale maintenance man-hour can be saved, the normal operation of the central range hood system is ensured, and the problems that the complex environment of a construction field and the fixed communication mode cannot meet the communication requirement are solved; meanwhile, only the sub-communication module is switched, so that the problems of high cost and great difficulty after sale are greatly reduced, and the popularization and the application of the central range hood system are facilitated.
