iBMS Integrated System of Building Management “Intelligent buildings” are buildings for different purposes and of different sizes, e.g. office buildings, trade buildings (super and hypermarkets), industry objects, schools, hospitals, mansions, private houses, etc. which possess integrated system of management and supervision. Class A intelligent buildings should provide users with comfortable conditions to make use of all their functions, and the workers with adequate level of work and everyone with high level of security.
Within this structure the crucial role is played by Integrated Management System. The system apart from fulfilling direct functions connected with maintaining optimal climate conditions and supervising energy consumption has at the same time to monitor and integrate other systems of the building, such as e.g. energy systems, lighting, heating, security systems.
System functions, among others, are as follows: - maintaining optimal conditions of work and equipment through direct monitoring and controlling of ventilation devices and installations, heating and cooling, - supervising cost-effective building exploitation through constant monitoring of energy consumption and lighting control in order to minimise exploitation costs, - supervising all technological devices and installations in the building and immediate alarming in case of emergency situations, - building security improvement through integration of controlling and supervising technical installation systems, visual monitoring, access control, fire alarm installation, DSO system, intrusion detection signalling. iBMS Technologies iBMS- is a modern IT system for network communication operation of automatic and tele- technical devices and dispersed workstations in the Internet, guarantee high efficiency of data and highest security level. iBMS is a constituent technology for controlling and monitoring system building of BMS objects. It provides scaled and stable communication platform, located in UNIX operating system. It offers its own iBasic language of communication programming (compatible with VisualBasic), data types, communication protocols, standards for creating network controllers and devices, protocol for joining various systems in “Peer-to-Peer” network, and many others. iBMS is of an open architecture, enabling full integration of popular, open communication standards such as LonWorks, EIB, Modbus, Ethernet, BACnet, CANopen and others, enabling full control over devices and their monitoring in local network and on the Internet Architecture iBMS architecture is logically compatible with star topology. Depending on the model and communication interfaces it possesses, the system can operate at the same time many network buses joined to one device. Parallel RS-232 or RS-485 can be joined with alarm switches, fire alarm, failure feeders, ventilation and air conditioning controllers, or any given devices possessing ability to series communication. All switches and series devices are treated in iBMS like networks and are operated in real time. A unit with iBMS software can operate as an individual system or in dispersed architecture, including many units cooperating with each other e.g. monitoring separate building subsystems such as lighting, access control, or alarm systems. Parameters received from local network objects can be in real time sent over to another unit in local network or on the Internet and collected in their data base. Operators from workstation level (on condition they are authorised) can log in to remote controlled units separately or monitor all the units at the same time by means of a common visualisation interface. The task of iBMS system is to allow installers access to all the parameters, from all joined units, in real time, with possibility to redirect communication, data collecting in base and free mapping of parameters between networks. Main features of the system: - Open architecture of controllers In iBMS technology all the networks and devices can have their own controller. The controllers operate communication with the system core, translating the standard of network variables into a format compatible with iBMS specification. It is a basic mechanism thanks to which integration of different networks on a common platform of data exchange is possible. - System security Because of very high requirements concerning work security in the open Internet environment, iBMS technology was located and fully integrated with OpenBSD operating system. Due to this iBMS makes use of the best protection solutions against potential attacks and integrated cryptography mechanisms for communication with the outside world. Communication between units in local network on the Internet is encoded as well as connections with the administration panel and communication with visualisation interfaces. Moreover a set of precautions intrusion was implemented with iBMS additional protections, such as: algorithms finding log-in errors, automatic password guess trials, strict control of the session period of the user and many others. Units equipped with iBMS software are fully adjusted to safe operating on public IP. To protect against various attacks or burglary trials, FIREWALL software was built in. - Greater reliability In cases when high level of reliability is required, units equipped with iBMS system can be configurated in cluster architecture. It ensures redundancy of collected information in separated data bases, increases the degree of reliability and makes it possible to ensure continuity of work of the whole system. The cluster can be made of two or more units configurated in “active/passive’ mode. The first unit - “Active” collects events from object network and devices for the data base and issues over to other units, operating in “Passive” mode. In case of failure, the units can be exchanged and in this way continuity of object functioning is assured. Logics of connections between units in local network or on the Internet is configurated by an installer. He can freely decide which parameters and where to send. - VDL technology VDL (Virtual Device Library) is a library of programming components made in Flash technology of Macromedia. Programming objects are elements of the library being counterparts of physical devices used in all the types of technical and tele-technical installations and automatics. The examples of such objects are: alarm sensor, bulb, heater, or electromagnetic valve. Each VD object is equipped with software for information projecting, communication with visualisation interface, rights service for users and additional optional functions connected with state configuration interface, rights operation (controls for level setting, value, change observation, etc). Communication operated by VD devices is two- way and operated in real time by visualisation interface. Virtual devices have been divided into ten theme groups: - lighting, - hvac (heating, ventilation, air conditioning), - power supply, (switches, sockets), - cctv (video monitoring), - fds (fire detection systems), - ids (intrusion detection systems), - acs (access control), - multimedia, - industry, (power generation, heat engineering, industry), - misc (miscellanous). - Remote control for visualisation Visualisation enables full control over tele-technical systems in the building. It allows observation of events in real time e.g. alarms, and controlling, changing of the present state of controlled devices in a quick and easy way. It can control switching on the light, setting optimal temperature or activating alarm system. All the operations are done by clicking a mouse on an object or moving a finger e.g. on a touch panel built in the wall Visualisation interface should be designed and executed individually for each building installation using specialist devices and adjusted to the screen on which visualisation will be presented (e.g. PC workstation, mobile phone or PDA device). - Planning of devices activity In order to obtain maximum exploitation savings connected with minimization of energy consumption the System can realise plans of activities of controlled devices, asked by an operator in three time tables in a form of a calendar, of priorities as follows: Weekly activities (repeated cyclically each week) - the lowest priority Holiday activities (usually realised in holidays) – the average priority One-time activities (deleted automatically after executing) – the highest priority. Each plan can be attributed to an individual point, individual device or programme in the system and can determine both the time of enclosing of a given device as well as parameters of its work in a give period of time (e.g. work in a day-night system). An operator is able to change all the parameters in time tables by use of the central computer or by remote connection. These operations are protected by the password. All subsystems can be visualised and connected in a logical whole by superior software. All algorithms and relations between working subsystems can be constructed in such a way that events in a given subsystem could be reflected in a different one if necessary. One such example is a connection between SSWiN and KD systems where in case of unauthorised intrusion into a given zone CCTV system reacts immediately by increasing record density or, if there is a high-speed camera nearby observing a moving person. Relations between subsystems must be realised on an application layer of superior software. - Optimisation of device starting-up time Temperature and lighting volume outside the building is very important for determining the time needed for rising temperature or switching on the lighting inside the building in order to reach the required level which is further necessary for minimisation energy consumption by devices. - Monitoring and energy consumption settlement The system can automatically read out from appropriate meters the consumption of electrical energy and water, providing at the same time data archiving and possibility to control changeability of consumption in time and determining additional parameters such as e.g. peak power. Adequate data will be presented in appropriate units allowing control of bills received from providers and accounting tenants of the rooms (e.g. restaurants). Summary iBMS -Integrated System of Building Management is to enable achieving complex goals in order to realise the most complicated controlling algorithms and work monitoring of all subsystems, installations and building devices. Exploitation costs optimisation, comfort and the highest standard of newly erected buildings require implementation of such technical solutions which will be able to meet the expectations of even the most demanding users. This solution will fully ensure the assumptions and will contribute to making up objects of the highest European and world standards. |
