I. Industry background

A total of 10 major accidents have occurred in the field of hazardous chemicals since 2015, with seven major accidents occurring from 2017 to 2019. Safety production of hazardous chemicals is the most important work in safety production.

1. Status analysis

1) There are many potential safety hazards in the production process and accidents are prone to occur

More than 70% of hazardous chemical products are flammable, explosive, toxic and corrosive in the process of production and operation. If an operator makes a mistake in the production process, it is highly likely to cause a fire, explosion, poisoning and burn accidents.

2) Traditional monitoring methods lag behind and have low intelligence level

The factory supervision system is seriously lagging behind, and the utilization rate of emerging technologies is not high. The traditional video surveillance method is mainly used for surveillance, video recording and playback, which cannot monitor and identify safety risks in real time and report early warning, leading to the low risk prevention ability of factories.

3) Serious data barriers and difficult to share across departments

The supervision of hazardous chemical production involves many responsible departments such as public security, fire control and municipal administration. The level of informatization is not uniform, the degree of data cooperation is not high, the information island is serious, and it is difficult to share the factory supervision data across departments, resulting in the lack of coordinated supervision by government departments.

2. Demand analysis

1) Intelligent monitoring

Real-time monitoring and automatic rapid identification of people, vehicles, objects and dangerous behaviors, such as face recognition, vehicle recognition, fireworks recognition, dangerous area intrusion, perimeter intrusion, timely detection of factory safety risks, make up for the lack of human supervision.

2) Intelligent alarms
