     Building automation system (BA)
    This system carries on the monitoring and the control to the following building units: the air conditioning refrigeration system, the water supply and drainage system, the electrical power distribution system, the lighting system, the heating system as well as the elevator electromechanical device and so on as comprehensively computerized. Through the monitoring, control and information records to each subsystem, it makes the realization of the dispersed energy conservation control and the centralized scientific management, so as to provide the good working conditions for the construction users, present the convenient management method for the construction superintendents, reduce the building energy consumption and the cost for the construction operators and offer the material base for the estate management modernization.
　
　

     Communication automation system (CA)
    This system guarantees the foundation of pronunciation, data and image transmission in the building. It simultaneously is connected with an exterior communications network, exchanging the information with the outside world. The communication automation system can provide the customers with the quick, effective, safe and reliable information services, including language text, graph, image and computer data and so on as the multimedia correspondence services.

 ★The comprehensive wiring system sources to the development of computer technology and communication. It is a product based on the integration of the construction technology and the information technology. This system aims at the signaling line of the construction interior intelligence system (computer and network, voice equipment, building automatic control equipment, video equipment and so on). This may cause the voice equipment, the data equipment, the commutation equipment and each kind of control device and information management system becoming connected with each other. Simultaneously, this causes these equipment becoming connected with the external communication network, thus progressing good voice correspondence, data picture processing, control and so on in that foundation, so as to complete the intellectualized construction.

　
　

     Office automation system (OA)
    This system uses the advanced information processing equipment, takes the computer as the center and uses the facsimile machine, the duplicator, the email (E-mail), the internet local area network and so on as a series of modernized-work and communication facilities, on maximum enhances the office efficiency and makes the improvement of work quality, environment and condition, so as to cause the work activity developing in the digitized direction and finally realize the free-paper work.
　

     Fire alarm and fire linkage automation system (FA)
    This system is playing the extremely important safety-control role in the modern intelligence construction. The fire alarm system is in an intelligent construction sub-system but it completely is separated from other systems or it makes the independent movement and operation in the network situation, completely taking the fire-fighting functional measures against natural disasters with the absolute priority. Through the information of different positions in building that smoke and fire control device provides, it carries on the alert and simultaneously starts the fire interlock systems, including the closing of air conditioning, the opening of the fume discharging installment, the starting of fire prevention special-purpose ladder and the starting of fire prevention system operation, with the urgent broadcast for dispersing the crowd, thus as far as possible reducing the life and property losses.
　
　

     The safety and security automated system (SA)
    This system mainly provides the environment without external interference, thus avoiding the personnel injury and the finance loss, preventing the illegal-event occurrence and creating security the convenient and comfortable work and living conditions.

     The background-music and emergency-broadcast system

    The basic function of this system is providing the background music or some essential broadcast information to the building, in order to create one kind of easy, harmonious, graceful and romantic atmosphere. When the fire or other dangerous situation occurs, the background music is automatically switched into the emergency broadcast system through the voltage signal which transmits through the fire prevention system, in order to inform the personnel to disperse and guarante the personnel safety.
