Fine chemical industry is a highly integrated technology-intensive industry, the core of which lies in the deep processing of primary or secondary chemicals produced by the basic chemical industry to produce specific chemical products with specific functions and uses, small batches, high purity, and multiple varieties. The fine chemical industry includes new materials, functional materials, pharmaceuticals, pesticides and pharmaceutical, pesticide intermediates and other industries.
At present, the production of fine chemicals is mostly intermittent or semi-intermittent reaction, raw materials, intermediate products and product varieties, processes are complex and diverse, and the reaction process is accompanied by a large amount of exothermy, which has the risk characteristics of easy to get out of control of the reaction, which is the main reason for the occurrence of fire and poisoning accidents.
On the one hand, the control technology can not be implemented in large quantities, on the other hand, it leads to a large number of operators operating on site, and once an explosion accident occurs, it will cause mass deaths and injuries. Therefore, compared with other chemical industries, fine chemicals are the hardest hit areas for safety accidents.
In recent years, in the process of promoting the upgrading and transformation of automation control in the chemical industry, the transformation and upgrading of fine chemicals is the top priority, and the personnel positioning system, as a part of the information construction, is an indispensable link, which can help enterprises improve their management level, improve emergency management efficiency, reduce safety risks, and prevent major accidents.
Features of Hangfei Optoelectronic Personnel Positioning System:
1. Closely follow the policy documents and meet the requirements of the Ministry of Emergency Management on the "Industrial Internet + Hazardous Chemical Safety Production" Pilot Construction Plan, "Industrial Internet + Hazardous Chemical Safety Production" Personnel Positioning System Construction Application Guide (Trial), and Personnel Gathering Risk Monitoring and Early Warning Function Construction Application Guide Based on Personnel Positioning System (Trial) issued by the Ministry of Emergency Management.
2. Using Bluetooth + LoRa wireless positioning technology, the system architecture is concise, the product is safe and explosion-proof, and the performance is good, the Bluetooth beacon is based on a new generation of circular polarization antenna design, with long coverage distance, more uniform RF magnetic field, and more accurate positioning effect; LoRa base station high-performance wireless data transmission, large data concurrency, wide coverage, strong penetration, and a small number of comprehensive deployment of equipment.
3. The software is rich in functions and easy to operate; The system has strong scalability, supports secondary development, and can realize data docking with third-party systems such as enterprise access control system, special operation management system, and intelligent inspection system, helping enterprises to achieve data exchange, sharing and integration in the construction of information platform.
Taking a typical fine chemical enterprise in Inner Mongolia as an example, the enterprise is a production and research and development enterprise of pharmaceutical raw materials and pharmaceutical intermediates, covering an area of about 300 acres, with more than 1,000 employees and 12 Class A production workshops, all of which are multi-layer structures. Through the construction of personnel positioning system, the plant focuses on the following functions:
1. All-round personnel positioning management without dead ends in the whole plant, through the three-dimensional electronic map, real-time display of the area, floor and specific room where the personnel are located, the system real-time statistics and dynamic display of the number of personnel in the factory area and each area, and the overall grasp of the personnel distribution situation;
2. For the most dangerous production workshops, storage device areas, restricted spaces, etc., the upper limit of the number of people in the area is set to achieve an overcrowding alarm; So as to control the number of on-site workers and prevent major accidents.
3. Aggregation risk monitoring and early warning is set up within the production area of the whole plant, and if the personnel gather in the early warning area exceeds the early warning threshold, the system will have corresponding early warning reminders, which can help managers strengthen on-site management and effectively control the risk of personnel gathering.
4. The system supports the restoration of the final position of personnel at a specific time, and once an accident occurs, it can provide a location reference for post-event emergency rescue and improve rescue efficiency.
As a professional positioning system provider, Hangfei Optoelectronics has been deeply engaged in the positioning industry for 9 years, and has successfully implemented and delivered a number of large-scale projects in the chemical field, which can provide practical positioning solutions for the actual situation of fine chemical enterprises, deeply meet the needs of enterprise management, and help fine chemical enterprises to refine their management.
