[0002] With the progress of society, people have higher and higher requirements for the quality of life, and the use of air conditioners has become a standard in office spaces, providing a comfortable office environment indoors in winter and summer. However, due to the public nature of office spaces, the power consumption of air conditioners in the space has no direct interest relationship with office workers. When using air conditioners, office workers usually set the air conditioner temperature too high or too low when starting the air conditioner in order to quickly reach a comfortable body temperature. There are also some employees who do not want to wear bulky cotton-padded clothes in the office in winter, so they take off their coats and turn up the air conditioner temperature to work. And occasionally after get off work, the air conditioner in an inconspicuous corner of the office area is forgotten to be turned off, causing the air conditioner electricity to be wasted all night.

[0003] At present, in the field of intelligent control of air conditioners, the most common ones are the wired remote control APP applications that come with air conditioners of various brands. They are usually used in home air conditioners. Customers use mobile phones to operate the corresponding APP applications to control and manage the air conditioners at home. However, there are many brands and types of air conditioners in public places, and the air conditioners are old and new. The existing wired remote APP cannot adjust the old air conditioner models, resulting in the inability to manage the air conditioners in public areas for energy saving. Because the electricity consumed by air conditioners is the main energy consumed by daily office operations of industry and commerce, intelligent control of their daily operations can save considerable electricity costs, which can reduce the operating costs of owners and meet the top-level guidance of the country for energy saving and efficiency improvement. Therefore, it is necessary to develop a cloud-controlled air conditioner smart companion device for air conditioner energy saving. Utility Model Content
