Since the seventies of last century, since the electrical power plant into the era of automation, power plant technology shape with the development of technology and development, the concept of wisdom in recent years the plant is particularly hot. From the point of view of the direction of development of thermal power plants, power plants upgrade to digital wisdom power plant is the inevitable road.
Wisdom plants through information and network technology to achieve plant-wide each control system, control interconnection equipment, etc.; three-dimensional virtual plant visualization achieved through virtualization technology; integrated use of big data, intelligent optimization control, intelligent decision support, intelligent technical means, and ultimately business assets within the plant lifecycle optimal allocation, optimal production quality control, to achieve the best economic and social benefits. Wisdom is essentially a power plant safety information + + efficiency, where security is the top priority, to do intelligence power plants must consider the safety of wisdom.
Security personnel cool Intelligence cloud security concept is the most important part of the safety management personnel working relationships with the fundamental operation of power plants, is a prerequisite for all security work, the existing problems:
The lack of timely security risk management and control and alarm means
Traditional security management to online program, the next line, the implementation of online feedback manner, and the line executed mainly in personnel, the lack of timely, advanced management tools, the lack of means to detect hidden dangers, failed to effectively implement security management of landing.
Not for duty in place effective monitoring and statistics
Safety regulations require that requires a security management positions for duty in place of regular inspection and two votes in field operations management in place based on the duty of the lack of effective monitoring and statistical tools. The need for duty personnel in the end there is no place to live?-Site dwell time enough? Patrol route that nothing is missing? These are difficult to trace, leaving a security risk.
Confined space work safety supervision and low reliability
Confined space operations using artificial supervision, low reliability, can not be effective early warning, danger of irreparable once, causing very serious consequences.
Lack of safety warning showcase platform, the lack of timely security pre-control means
Typically power plants have been built or ready to construction safety production management-related video surveillance system, building staff area positioning system and the production system, the above system will be composed of plant personnel with comprehensive security management and control platform device, it will produce a large number of security management information flow and management data, but the current system through the transverse vertical integration independent, did not achieve the information flow between the system and data, such as live video information, personnel location information, production information so scattered in the respective sub-systems, not all levels emergency management personnel to provide comprehensive management and decision support platform, the lack of centralized data display platform.
Personnel management solutions
Can be drawn from the above-mentioned problems, the problem is that the safety of personnel working at the time of uncertainty, if we do a good job positioning management personnel will be able to solve the problem. Based on this cool cloud UWB technology use ultra-wideband technology as the main body, Lora technical assistance for the design direction, with UWB technology penetration, low power consumption, multi-path effect, low high security, system complexity, precise positioning and other characteristics, combined with a complex power plant operating environments and different business requirements, design a three-dimensional visualization management personnel positioning system combining software and hardware (Figure I), for plant personnel to address security issues.
Positioning System Scheme
The system uses three-dimensional virtual power plants as the main function display platform, two-dimensional plan as an auxiliary display platform. The main job ticket integration operation order, the assigned personnel, hidden defect, duty place, inspection, and other information related to operational safety, while access to video surveillance equipment, access control equipment, positioning device, and various information integration of staff position, and ultimately the operator position, see the linkage with the supervision and management work content, access status, video surveillance.
● real-time location
Commission staff and outside workers carry the label positioning, constantly ranging between electronic label and positioning equipment, real-time location and displayed on the three-dimensional map. While achieving location tracking, key personnel monitoring, historical trajectory query.
● work area management
For easy management and rapid positioning and viewing video linkage, we put the whole plant is divided into N work area, make the appropriate classification based on the level of risk the work area safe, easy to focus on monitoring key areas, hazardous area real-time monitoring, staging area laid electronic fence monitoring, improve management efficiency.
● Job distribution management
The job ticket associated with the audience and each region hidden defects to achieve remind distribution operations, rapid query operations, major work in three-dimensional platform.
● management of assigned staff
Positioning technology to achieve real-time location supervision of peripheral staff by the density distribution of the assigned personnel, historical trajectory queries, electronic anti-intrusion fence, supervision and limited space operations, combined with the realization of the phone APP inspections illegal entry management.
● routine patrol duty in place and management
According to the rules in place for duty and routine inspection of the plant in conjunction with positioning technology, supervision and inspection for duty in place: the system records and personnel for duty in place of inspection time, frequency and routes, and to provide duty rate, absenteeism statistics, while not yet reached corresponds to the staff, route deviation inspection, inspection is not in place to alert.
● video surveillance linkage
Automatically retrieved based on the corresponding video surveillance personnel current position.
● other location-based applications to expand
Visitor location management, industrial equipment management, vehicle location management, location management and other important equipment.
● wisdom security brain
Massive historical location data generated in the course of the power plant, habits data, security management data and so on. System uses big data analytics platform abnormal behavior analysis and forecasting security risks, change from passive safety to active safety.
By positioning personnel, video surveillance, video and key regional linkage, to achieve the assigned personnel, cross-border police officers patrol outside the appointed officer low security level alarm, no alarm signal or overtime work, timely field operations personnel to monitor the situation, especially in high-risk work effectively to achieve security personnel real-time monitoring and risk control.
