Design And Implementation Of The Power Room Access Control System

The rapid development of power industry, causes building a large room (substation). As the room (substation) has a wide distribution area and quantity, the security of equipment and property requires a lot of manpower, time, money, so the goal of safe efficient low cost operation and maintenance can not be achieved .Particularly to those unattended substations, the original key to open the door can not be convenient, there are some security risks.Access Control System, also known as access control system, control access and egress feature recognition through the entrance and exit of personnel to intelligent management system. Include signs of identification, determination, and access control permissions. Access Control System can be configured on the staff of the authority, but also on the staff or the entrance of the status information in real-time recording, can be recorded for statistical analysis, so as to ensure well documented, be sure to set the scientific and ensure system practicalThis access control system was designed primarily to save investment and need to use the original part of the equipment, because the original system of front-end equipment configuration is low, and demanding front-end control procedures, in general,it is a smaller footprint, higher efficiency, demanding on the development of language through repeated demonstration, the entire system development tools selected for the VC, the data source using ODBC, data source using ADO for the operation.Ideas in the system, uses the object-oriented design. With the application of main access control system and the application of scale, new functional requirements will continue to the proposal, its scale and complexity of the rating of exponentially growing, So keeping them is more difficult and costly. Compatibility in the system, mainly through the device commands corresponding to the table different approaches to different protocol conversion equipment. Through the system of functional analysis to determine the system and the front gate of the main commands between devices, such as open, closed, etc., determine the instruction code. Equipment Directive through the crack and the original instructions for new equipment, added to the device type associated with the instruction code corresponding to the table, when issued in order, first read the device type, and instructions for the corresponding device can be issuedAccess control system consists of global management and control of software management systems and operations to respond to a variety of instructions corresponding hardware platformIn this thesis, the software management system uses the latest software design techniques, object-oriented design patterns through a systematic analysis and design. Can be applied to a variety of network environments, compatible with a variety of access control equipment can be carried out on the existing access control system upgrade and protect the original capital investment, but also the maximum increase system scalability. Flexibility to choose the data source, you can choose according to the system of large-scale Oracle, small to Acess, suitable for various environments.This study mainly in the following points:1.Access Control System Analysis: introduction to access control system, including introduction, component diagram, development process, design principles and design standards.2.access control system control platform for functional analysis: identification access system control functions of the platform, architecture3.access control system design: the choice of development tools, function model, data dictionary, Serial Communication4.The access control system to achieve: details of server-side access control system, all the features of the client.5.Follow-up Development Outlook access control system: the shortage of access control systems, an improved direction. This system is developed for a particular user-specific circumstances, the main value is to use existing equipment and provide reserve for future expansion interface, easy operation, complete functions, the corresponding fast, low failure rate, get user acceptance. Enterprise remote management platform for enterprise safety escort.
