Building Management System Bms Server Software Computer Science Essay

Building Management System Bms Server Software Computer Science Essay As we known BMS are created to controlled central computer method which has 3 basis functions, which is controlling, monitoring and also optimizing. However, there is a BMS server software to facilitate the works of facilities management which to functioning within the building and also to fulfill the building operation and maintenance. General Requirement The BMS server system is composed of 3 sets of reducant computers, which communicate with several kinds of input or output devices, subordinate computer system and higher order computer systems. The sections described the software required to achieve the desired functionality of the BMS. The software design is based upon real time data acquisitions and control capability. Data including point values, parameters, messages, instructions, databases access statements, master clock synchronization and other forms of computers data exchange may originates from or be destined for other sub-system and computers and database which may form pat of TAMS. It is responsibility of the BMS Sub-System Contractor to develop, test, document and debug software interface routines and supporting hardware to accomplish the interface requirement of BMS to TAMS and any other system or sub-system with which the BMS is required to communicate. The BMS Sub-System Contractor will provide software for the BMS Sub-System, which is proven in actual field installation of a similar size and scope. The BMS Sub-System Contractor will provide complete information and responses with tenders including reference sites, name, and telephone number of reference site contracts. Software Licensing KLIAB respects the propriety nature of certain software. Commercially available software purchased from a third party such as Microsoft Windows, UNIX, OS/2 and similar software packages are provided. Licenses are bound with the operation and maintenance manuals for BMS system. BMS manufacturer’s proprietary software is provided fully licensed. All BMS manufacturer’s proprietary software will have complete sources codes, programs listings and supporting information deposited in an escrow account at the BMS Sub-System Contractor’s expense. BMS Server Software Operating System The BMS server computers will utilize a multi-user, multi tasking operating system designed for client server operations. The operating system will support all the required software functions and application described in the BMS specifications. Standard services supported by Operating System on serves will include the following: Multi- tasking Multi- user support POSIX 1003, 1 compliance TCP/IP, SLIP Network Support Network File System (NFS) C language complier The BMS Sub-System Contractor will provide to the SMC one complete set of operating system user manuals and programmer’s references manuals bound as part of each BMS Operation and Maintenance Manual. BMS Software Executive The BMS Sub-System Contractor shall provide a complete BMS software executive module which provides at minimum: Workstation communication sport Printer quering and tasking I/O Channel support for up to 99 communication channel Disk optimization routines On-line database backup and restoration Memory management functions Software watchdog functions Networking functions Housekeeping functions Diagnostic routines Server Redundancy Software The BMS Sub-System Contractor will provide six complete server computers arranged as three sets of redundant ‘hot standby’ server system. Each server computer are equipped with all hardware and software with complete capability to support the designated BMS tasks.
