The BMS will have been controlled executive devices operate through information exchange of each infrastructure technology system by operators, ensuring the technical elements as well as safety, security and energy efficient operation, avoid unnecessary waste, reduce the costs of operating the infrastructure technology systems, improve the initiative in management, operating, repair and upgrade technical problems ...

With opening protocol, the BMS will be allowed to connect the high integration and associate with the control utilities, monitoring, integrated communication equipments, digital control equipments of engineering systems has created the BMS to meet fully requirements of technical design.

With many applications in the engineering fields, the BMS software will have been allowed to provide solutions with different building infrastructure technology systems. One of these applications is the module software, which is allowed to be integrated connecting fully electricity, lighting, elevator up to BMS, the connection also contributes to create an overall integrated system.

For the North An Khanh New City Development project, the BMS has ability to integrate technical subsystems by standard protocols. The system will have been provided hardware modules, appropriate software for building infrastructure technology systems and integrated to BMS. Integrated conditions are possible when the software is aptitude for high-integrated connection to all of technical systems using opening protocols, common in the industry as BacNet, LONmark, Modbus, Profibus, EIB, M-Bus, P2 in accordance with the SSPC135/1995 of American ASHREA Association and other BacNet products manufacturers.

DDC control equipment:DDC (Direct Digital Controller), mission of controller is the connection of all control and monitoring equiments. The devices should be controlled and monitored such as emergency ventilation, fire alarm and fire fighting, plumbing, gas equipments. DDC controller is also capable of remote control and monitoring when creating the FLN network by integration.The digital control cabinets are built with 72 MB RAM memory of the processor. Processor is able to store all the information and control program for 30 days without power supply by farming battery attached. The control cabinet can be connected to the server of central control room by via Ethernet LAN TCP / IP 100 BaseT (EALN: Ethernet Automation Level Network).Operator can set the control program and then transmit over LAN TCP / IP Network from the servers to the DDC control cabinet, communication network allows transmitting control drivers on the LAN Networks to control devices without having to stop the control operation program or disrupt the operation of equipments in the building.DDC controllers allow the manager access by personal computers of control operation staffs, make the amendment of work program of the equipment, programming in place. Same time, processors of DDC built in embedded applications help operator set up the driver for the device on the computer control application of Microsoft Window operating system.The DDC controllers have high independence, when the network system from server has problems, the control cabinet has the ability to implement control programs of devices depend on RAM memory.To make the connection of integration of technical systems, control equipments with different protocols, the DDC is capable to fit integrated and opening processors which have protocols corresponding with Bacnet, Lonmark, Modbus, EIB, M-Bus, Profibus... to make transfer of the information to connected system to. This information is sent to the center control computer by via the EALN network and able to be displayed on the screen of the computers of operating stations through the graphical interface.Each DDC is able to establish three Master / Slave control networks, each network includes 32 TEC local digital controllers (Terminal Equipment Controller) to control local devices such as emergency ventilator, pressure fan...When there are problems of power supply, the DDC controller will automatically store information related to the control operation, the parameters are kept at DDC during time appointed by operator from 1 to 30 days to ensure the requirements about storing data. DDCs Implement control and monitoring of devices of the system: Manage operation status of the pressure fans;

Receive fire signals from the central fire alarm panel;

Receive signals from water supply and drainage system...Network structure of the BMS allows each EALN to establish peer relationship of 100 DDC control cabinets and accept the 1000 DDC control cabinets in the entire control network system.Thit b iu khin DDC:

2.1.5. Communications network

EALN control management network:

TCP/IP LAN Ethernet is the communication network of the building management system, the direct digital controller (DDC) of the design of techniques used for the building will connect each other and the server control computer of BMS.

BMS system will create own infrastructure network to serve for connection the center computer stations to the operation computer stations distributed in the buildings. Ensure security in operating systems most effectively.

In the MDF room has a Core Switch, which connects the central control computer to LAN network system of the building.

In each block of the Mixed Use and Apartment has been set the Access Switch to connect all the DDC in the floors with computer of stations.

Two regions of the building are Mixed Use and Apartment, because of geographic location away from each other therefore BMS is designed separately. For link between blocks in each area using fiber cable system.2.1.7. Mng truyn thng

FLN local control network:

Each DDC controller supports three FLN networks according to Master/ Slave of communication mechanism. In Master/ Slave Network, DDC acts as a Master controllers and 32 TEC local controllers act as Slave. Master / Slave Network use RS485 of industry communication standard, the protocol used on network is P1, a communication protocol of the local equipment.FLN communication Bus network use a wisted pair wire of cablet coated metal according to AWG18 standard of America. Communication speed can reach 4800 - 9600 B/s. FLN control network manages local control equipments such as the inverter adjusting speed of the engine (VSD). For the integration of Modbus devices, the FLN network will support to transform protocol, ready for connection.Mng iu khin cp trng FLN:
