China has become the first reputable country of elevators, but the overall failure rate of the elevators is still high. Taking the data of '96333 elevator emergency disposal platform' in Hangzhou city as an example, 11 ten thousand Hangzhou city elevators in 2017 receive 64040 alarm telephones, begin elevator emergency disposal 11723 (wherein, the trapped person fault is 6239 and the equipment fault is 5484), rescue trapped people total 13762 people, receive 175 alarm telephones on average every day, begin on-site emergency disposal 32 and rescue trapped people 37. With the continuous and high-speed development of the elevator market in China for 20 years, a large number of elevators in use enter the aging stage, the number of the elevators used for more than 15 years reaches 43 thousands, and the safety risk is continuously increased. Meanwhile, with the rapid aging of the population structure in China, the requirements of the social public including disabled people on the quality safety of the elevator are increasingly improved, and the emergency alarm and emergency rescue of the elevator attract high attention of the whole society. According to the technical rules and standards of elevators in China at present, a voice intercom system connected with a duty room on duty is generally adopted in emergency alarm of the elevators, the voice intercom system is not suitable for disabled persons with language and hearing impairment, the alarm reliability is poor, the execution efficiency and the safety level are low, and the humanized safety requirements of passengers are more and more difficult to meet. For the situation, relevant elevator technical rules and standards in China are revising to put higher requirements on an elevator emergency alarm device and an intercom system, and clearly stipulate that a remote alarm system meeting the GB/T24475 requirement is to be set, so that a two-way intercom system is ensured to be continuously linked with rescue service.

In order to solve the above problems, various solutions have been proposed. For example, chinese patent document discloses a utility model patent of smart elevator rescue monitoring and glaring media platform [ grant announcement no: CN 202464976U ], relating to elevator intelligent technology. The utility model discloses an including "elevator thing allies oneself with intelligent media device", have remote alarm function to a certain extent, its external structure schematic diagram is seen in this patent specification figure 3.
