Uwb positioning technology helps personnel to position material safety management, and chemical safety production has always been concerned. With the advent of the industrial Internet era, the transformation of intelligent informatization of personnel safety management in chemical plants is also crucial. The chemical plant personnel positioning adopts UWB high-precision positioning technology. By wearing positioning tags, it deploys and installs positioning base stations in the park. Through face recognition and visualization system, it realizes the real-time positioning of personnel in the park, greatly improving the work safety and processing efficiency of employees.
1. Real time personnel positioning
The personnel positioning system of the chemical plant can locate the position of the factory employees in real time, and query whether they are on duty, overtime, etc. Through the personnel positioning system of the chemical plant, 2D/3D free switching map can be realized to view the movement track. For visitor management, visitors' route, stay time, activity track and other information can be used to prevent immigrants from entering dangerous areas and causing safety accidents, and digital and intelligent processing can be completed.
2. Chemical plant personnel positioning important equipment and materials
Uwb positioning technology can detect the real-time location of fire first aid equipment and products, facilitating the rapid call of products and risks; It can intelligently dispatch and control mobile equipment, material transport vehicles and chemical garbage cans according to the location.
3. Personnel positioning in chemical plant to realize intelligent patrol inspection
The personnel positioning system of the chemical plant is connected with the inspection system, and the inspection point, inspection range, inspection time, inspection route, inspection personnel, inspection dwell time, and inspection cycle can be customized. Prevent personnel from misoperation, omission and reoperation, and effectively ensure that the inspection policy meets the requirements for safe handling.
4. Restrict electronic fence behavior
Electronic fences can be set in important areas such as hazardous chemical raw material storage area and hazardous equipment storage area. Once people or materials enter the area without authorization (tourists enter the hazardous area, employees, overtime, etc.). The system immediately sends out an early warning to prevent security incidents and ensure the safety of personnel, materials and areas.
5. Data statistics and analysis
Uwb positioning technology can make comprehensive statistics on the data of positioning personnel and equipment, and intuitively draw charts. It can view the accumulated number of people on site, the number of on-site real-time personnel and equipment, the on-site heat distribution, the real-time change of on-site heat curve, the real-time monitoring of on-site fence status, the random flow of chemical raw materials in a certain area and other information to prevent personnel from handling negligence.
Intelligent work "Industrial Internet+Safe Production of Dangerous Chemicals" provides a comprehensive solution for the key construction scheme, and the chemical plant personnel positioning system uses covers to ensure the safe operation of "people, machines, materials, environment, and management". It greatly improves the safety and efficiency of production and reduces the cost of enterprise management.
Why is the orientation of chemical plant personnel inclined to UWB technology? As a commercial positioning system with high accuracy and stability, UWB technology is the key requirement of B-end enterprise security control system in the Internet of Things era. UWB has ultra wideband pulse signal to achieve high-precision real-time positioning and positioning capacity. The personnel positioning of the chemical plant can achieve up to 10cm in the actual environment. The positioning accuracy of other positioning technologies is indeed limited, even if it can achieve the UWB positioning accuracy, overall deployment cost and system stability. UWB is the main positioning technology for chemical industry positioning.
1. Three safety problems of chemical plant
a. Lack of real-time supervision: failure to operate according to work regulations, resulting in production safety accidents, and no effective real-time management and analysis system.
b. Lack of active intervention: there is no active safety reminder system or emergency help system in hazardous areas such as high-temperature and high-pressure, flammable and explosive, toxic and harmful, highly corrosive liquids or gases.
c. Lack of accurate rescue: In case of emergency, it is impossible to know the distribution of on-site personnel. At present, there is no effective rescue assistance system.
2. Advantages of uwb positioning technology in chemical positioning application
Strong anti multipath capability: under strong multipath and multi occlusion conditions, the direct path signal can be correctly received
High signal recognition: when the pulse is as short as 2-2nS, the first arrival path signal can be separated from the above 30cm multipath signals in the time domain. At the same time, due to the high signal frequency, the ability to penetrate objects is strong.
High positioning accuracy: 0.1~0.3m
3. Chemical positioning solution of uwb positioning technology
According to the UWB chemical positioning solution, the customized application function is realized under the positioning technology, combined with the rapid secondary development of the actual business, based on the positioning technology, the UWB+Bluetooth positioning technology integrates location awareness, integrates location awareness Zigbee low-power wireless data network, cameras and environmental sensors, and integrates the access control execution device.
The personnel positioning system of the chemical plant brings all production and operation areas of the plant into the scope of wireless rescue network supervision. When production and operation personnel encounter difficulties anywhere in the community, press the emergency rescue button on the card, and the computer screen of the person on duty in the monitoring center will immediately display the location of the production and operation personnel and their personal identity information, providing guidance for quick response and emergency help of rescue personnel. At the same time, it can also monitor the real-time position of employees for standardized management and reasonable scheduling.
Chemical plant personnel positioning UWB high-precision positioning is adopted to comprehensively improve safety, lacking weak links. As different industries have different requirements for the hardware and software functions of the positioning system, different solutions are proposed to help enterprises achieve personnel security management.
