[0002] With the accelerated pace of smart grid construction, the development of prefabricated cabins has become increasingly mature, and the requirements for cabin environmental control systems have gradually increased. At present, the intelligent integrated environmental auxiliary control centralized control system for prefabricated cabins generally uses different equipment systems such as general auxiliary control systems, environmental monitoring, and hydrogen leak alarm monitoring to respectively realize the environmental parameter monitoring and environmental status control functions of the prefabricated cabin environment site, thereby meeting the prefabricated cabin on-site environmental monitoring needs. The cabin environmental control devices need to operate independently, with single equipment functions. When using different monitoring equipment, each device can only realize partial functions.
