On November 18, at the 18th China (Shenzhen) Hi-Tech Fair, Zhejiang Science and Technology Department selected exhibitors - Zhejiang New Zelin Science and Technology Co., Ltd. to release a resolution at the product launch event Elevator safety management program system - ladder. The picture shows the new Zaibing and Hangzhou Yuhang government signed Yu ladder landing Yuhang strategic agreement Elevator is convenient for people's daily travel the main means of transport. With the surge in the number of elevators and the aging and maintenance of the elevators, elevator safety accidents are frequent and the elevator people and injuries in various places are also commonly reported by the media. In 2015 alone, the number of reported elevator accidents exceeded the national average From 50. Elevator safety has aroused great concern in society, AQSIQ issued a continuous document, requiring the strengthening of elevator safety management. How to solve the elevator safety problems effectively run? In response to this problem, after more than two years of research and development to overcome a number of technical problems, Zhejiang New Zelin Technology Co., Ltd., with IoT technology to structure a set of intelligent management system for elevator safety - ladder. Ladder in the safety management to achieve an advance warning, comfort and disposal of things, retrospectively after the three effects. Elevator ladder by the four major technical level of the elevator to achieve effective safety management: (1) Signal Transmission: Stable transmission of sensing information with PLC technology; (2) Video Analysis: Video algorithm to effectively identify the status of the elevator door switch, foreign objects door, improper boarding behavior. And can discourage the occurrence of uncivilized riding by video intercom; (3) real-time physical examination: the main prevention to improve the safety of the elevator. By the online sensor records combined with offline maintenance record, real-time elevator safety examination, to make early warning; (4) Intelligent Processing: The ladder is operated by the intelligent system independently on the detection, management and disposal of the elevator. The picture shows the ladder structure The trial operation of the ladder in Hangzhou Binjiang District has been successful and has been well received by government departments and users. At the conference, Mr. Hu Hao, chairman of New Zaanding Company, announced the official launch of Cloud Ladder 3.0. Hangzhou Yuhang District Government and Zhejiang Xin Zailing Science and Technology Co., Ltd. signed a strategic agreement to settle Yuhang in this conference. In 2017, 25,000 elevators in Yuhang District of Hangzhou will implement intelligent safety management. Xin Zaizhen CEO Hu Hao expressed his hope that through the ladder to reduce the incidence of elevator accidents, is committed to the ladder project from Yuhang copied to the country, so that people take the ladder out
