Under the trend of large-scale industrial production, the construction of chemical parks is booming. With the hot topic in the field of safety accidents in chemical parks, the public awareness of emergency management has increased remarkably. In response to the current fragmentation dilemma of chemical industry in China, it is necessary to improve the emergency management mechanism. In the paper, four evaluation strategies are proposed on the basis of existing research for the construction of emergency management system in China Chemical Industry Park.

The function of traditional elevator monitoring system is relatively simple. It cannot realize on-demand maintenance and fault warning. To solve such problems, this paper builds an intelligent monitoring system of elevator Internet of Things based on multi-sensor information fusion, bus communication and probability and statistical analysis technology. Managers can access the control platform through smart terminals or web browsers to achieve data query, video monitoring, alarm management of the elevator system, health management and other functions, which can help managers detect hidden dangers of elevator safety in time and ensure safe and efficient operation of elevators.

There are many problems in traditional elevator industry, such as, poor maintenance, unclear elevator operation information and single supervision platform. In this paper, a smart elevator management system based on “BIM + IOT” is proposed. This system combines BIM Technology, Internet technology, embedded technology and software management technology with elevator intelligent management system. It realizes the video monitoring of the whole equipment, equipment status monitoring, multi-party joint rescue and multiplatform information sharing of Government, Enterprise, Property and Maintenance. The system is composed of hardware and software, which realizes the functional coupling between elevator safety and intelligent building, and provides a research direction for Intelligent Building.

The campus is a place where social talents are highly gathered. If an emergency occurs improperly handled, it will directly affect social stability. With the hot topic in the field of safety accidents in campus, the public awareness of emergency management has increased remarkably. In response to the current fragmentation dilemma of campus in China, it is necessary to improve the emergency management mechanism. In the paper, four evaluation strategies are proposed on the basis of existing research for the construction of campus emergency management system in China. It is imperative to build risk assessment capabilities and a collaborative mechanism for campus emergency management, while the campus should focus on the grassroots organization of student management and improve the legal system.

In China, the research on detection technology of elevator fault is relatively late, and most of the technologies are only in the research of theoretical stage and have not yet been tested by practical applications. Organize and summarize the relevant literature and personal research. The research status of fault diagnosis, Prediction and Health Management technology at home and abroad is summarized. And the latest research of elevator fault prediction and health management technology is analysed. Finally, the challenges and the development trend of elevator fault health management are expounded.
