Embodiment Construction

[0027] figure 2 A block diagram showing the architecture of a building management system according to the present invention.

[0028] A building management system (BMS) according to the present invention includes a BMS controller 50 for centrally controlling a plurality of subsystems 60 installed in a building and connected through a LonWorks network, and as one of the subsystems 60 and including an outdoor unit and Air conditioner system 70 for indoor unit.

[0029] Subsystems 60 may include various systems in a building, from simple sensing systems to complex control systems such as equipment, power, lighting, crime prevention, access control, elevators, disaster prevention, and air conditioning systems. Each subsystem 60 is connected to one of the Lon devices 61 to 63, and can be centrally controlled by the BMS controller 50 through the LonWorks network.

[0030] The air conditioner system 70 may be an air conditioner system including a plurality of interconnected indoor...

Abstract

Disclosed herein are a building management system (BMS) and an operating method thereof. A BMS controller of a LonWorks network integrally controls a multi-air conditioner system which uses a different communication scheme, without modification of the structure thereof. The building management system comprises a BMS controller (50) for centrally controlling subsystems (60 and 70) installed in the building and connected to a LonWorks network (N 2 ), an air conditioner system (70) including a plurality of outdoor units (71) and a plurality of indoor units (72) connected to the outdoor units, and a Lon gateway (80) for converting data of an air conditioner system network (N 1 ) into data of the LonWorks network (N 2 ), and vice versa, to enable the BMS controller (50) to centrally control the air conditioner system (70). The building management system can incorporate a multi-air conditioner system which utilizes a different communication technology, without modification. The building management system also facilitates low-cost installation of an integrated control system in the building because each one of the indoor units constituting the multi-air conditioner system can be separately controlled without the need for a communication module to be connected to each indoor unit.

Description

technical field [0001] The present invention relates to a building management system and its operating method, more particularly to a building management system and its operating method, wherein the network structure of the multi-channel air conditioner system based on the RS-485 communication scheme can be changed , the multi-channel air conditioner system is controlled by the building management system (BMS) controller of the Lonworks network. Background technique [0002] In response to modernization of building equipment in recent years, control systems capable of automatically controlling various subsystems installed in buildings, such as power supply / lighting and fire / security subsystems, have become popular. A building management system (BMS) capable of integrally managing these subsystems has been actively developed. [0003] Figure 1a with Figure 1b A block diagram showing the architecture of a conventional building management system. [0004] Figure 1a The co...
