An Electronic Procedure System Supporting Team Collaboration

Abstract

The invention discloses an electronic procedure system supporting teamwork, comprising a power plant instrument control network system and a power plant local area network system, the power plant instrument control network system and the power plant local area network system form a T-EPS system; the power plant instrument control network system The system and the power plant LAN system communicate through a one-way gateway; the T-EPS system is composed of multiple clients and servers; the server is composed of a master server and a slave server; the T-EPS system adopts multi-layer client / Server-side architecture; the server is provided with a data service layer and a business processing layer, and the client is provided with a functional interface layer and an interface display layer. The electronic procedure system supporting teamwork of the present invention reduces improper communication among team members, enhances team situational awareness, improves team overall efficiency, avoids human errors, and thus improves the overall safety and economical efficiency of nuclear power plants .

Description

technical field [0001] The present invention relates to an electronic procedure system, in particular to an electronic procedure system supporting teamwork, which belongs to the management and technical support in emergency facilities such as personnel in the main control room of a nuclear power plant, a technical support center outside the MCR, and an emergency command center Personnel communication system technical field. Background technique [0002] The main control room of a nuclear power plant is a highly complex and uncertain environment. The completion of the operator's task requires the cooperation of the team members; the nuclear power plant team is composed of multiple members, generally divided into operators (such as reactor operator, steam turbine operator, electrical system operator), deputy chief / chief / crew chief, technical consultant on duty, supervisor / operation manager on duty, etc. In addition, there will be several On-site operator, whose duty is to mon...

Problems solved by technology

In September 2011, IEEE released the IEEE Guide for HumanFactors Applications of Computerized Operating Procedure Systems (COPS) at Nuclear Power Generatink Stations and Other Nuclear Facilities (IEEE Std.1786-2011), which is an electronic procedure from the perspective of human factors engineering The design and use of the system provide guidance, and abstract three types of electronic procedure systems according to the functional level of the electronic procedure systems that have been developed in various countries; but these systems provide consistent information for all team members. The following factors are not considered: 1. The task characteristics of different team members are inconsistent: for example, the operator generally only needs to pay attention to his current task, while the duty leader needs to pay attention to the operation status of the entire power plant, and assign and coordinate The task of the operator; all users use a unified interface to bring about information redundancy and lack of functions, which brings inconvenience to the operation

Due to the lack of design considerations in this aspect of the system, it is inconvenient and error-prone to only rely on management regulations to coordinate the operation of team members

3. Negative impact of the electronic procedure system with dynamic information of the power plant on team communication: After the digitization of MCR, especially after the electronic procedure integrates the dynamic parameters of the power plant, every member can see the power plant and the implementation All levels of information and execution results required by the procedures, the subjective willingness and need to communicate are reduced, and the impact on the team's situational awareness is more obvious

Moreover, each member's operation mode facing their own VDU increases the independence of members and reduces transparency, which has a negative impact on the team characteristics of the operating team.

Therefore, digitalization also brings certain hidden dangers to safety; the emergence of the above problems, on the one hand, did not fully analyze the impact of the introduction of electronic procedures on team operations, and on the other hand, it was stuck in the stereotyped thinking of paper-based procedures. Make full use of the advantages of digitalization; at the same time, as the scope of the electronic procedure system gradually expands from emergency operation procedures (EOP) and abnormal operation procedures (AOP) to general operation procedures (GOP), system operation procedures (SOP) and serious accidents Guidelines (SAMG), the above problems are becoming more and more prominent
