Integrated building management system and control method using middleware module {TOTAL BUILDING MANAGEMENT SYSTEM USING MIDDLEWARE MODULE AND CONTROL METHOD THEREOF}

The present invention relates to an integrated building management system using a middleware module and a control method thereof, and more particularly, to a transmission control protocol / Internet protocol in an integrated building management system (hereinafter referred to as a "TCP / IP protocol"). The present invention relates to an integrated building management system using a middleware module that minimizes development and maintenance costs by constructing an integrated system irrespective of the type of the subsystem using a plurality of subsystems using middleware and a control method thereof.

Recently, with the modernization of building facilities, an automatic control system that automatically controls various subsystems such as air conditioning / hygiene, cooling, power / lighting, parking, elevator, etc. installed in the building is spreading. Development of an integrated building management system that can be managed efficiently is underway.

1 is a block diagram showing a configuration of a conventional integrated building management system, and a plurality of sub-systems (10 to 12) for controlling the air conditioning / sanitation, power / lighting, parking, elevator, etc., respectively, as shown therein; A building integrated management system (50) which receives information transmitted from the plurality of subsystems (10-12) through a TCP / IP Ethernet LAN (1) and manages it; It is composed of a database server 60 for storing the data transmitted from the plurality of subsystems (10 to 12) and for transmitting data in accordance with the event occurred in the building management system 50, the plurality of subsystems (10) And 12) a plurality of direct digital controllers 40 to 48 which collect data at each control point and transmit the data to the upper layer; Gateways 30 to 32 for transmitting position information of data transmitted from the plurality of direct digital controllers 40 to 48 to upper positions; Subsystem servers 20 to 22 converting the data transmitted from the gateways 30 to 32 into valid data desired by the higher level system and transmitting the same are described in detail.

First, the plurality of direct digital controllers 40 to 48 in the plurality of subsystems 10 to 12 control the operation of each control point, collect data, and use the dedicated communication line 2 to control the respective gates. It is transmitted to the subsystem servers 20 to 22 via the way 30 to 32, and the subsystem server 20 to 22 transmits it to the building integrated management system 50.

In this case, the plurality of subsystems 10 to 12 respectively perform data communication and command transmission operations with various devices therein using a unique protocol set by the manufacturer, and thus, the plurality of subsystems 10 to 12. When the data is to be transmitted to the building integrated management system 50, the unique protocol is converted into the TCP / IP protocol by the respective subsystem servers 20 to 22 and transmitted.

Therefore, the manufacturer of the subsystems 10 to 12 must separately prepare a TCP / IP protocol conversion part for connecting to a higher system, that is, for converting to a protocol set by the manufacturer of the building integrated management system 50. do.

That is, when adding a subsystem using a protocol different from the communication protocol used in the conventional sub-system and the building integrated management system as described above, protocol compatibility is very difficult, and when adding or changing a function to the building integrated management system. There is a problem in that the maintenance cost increases as the TCP / IP protocol for higher data communication is changed.

In addition, it is very difficult for a system administrator to implement without understanding the standard / non-standard protocols of each subsystem, and in addition to knowing the address and exact protocol of each subsystem in the building integrated management system, As data is transmitted, its implementation is very difficult.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, using a plurality of subsystems using standard and non-standard protocols using middleware such as JAVA, DCOM, COBRA, etc. Therefore, an object of the present invention is to provide an integrated building management system using a middleware module that minimizes development and maintenance costs by building an integrated system regardless of the type of the sub system, and a control method thereof.

Hereinafter, with reference to the accompanying drawings, the operation and effect of an embodiment of the present invention will be described in detail.

Figure 2 is a block diagram showing the configuration of an integrated building management system using the middleware module of the present invention, a plurality of subsystems (100 ~ 102) for controlling air conditioning / sanitation, power / lighting, parking, elevator, etc. )and; A building integrated management system (150) for receiving information transmitted from the plurality of subsystems (100 to 102) through a TCP / IP Ethernet LAN (1) and controlling it; A database server (160) for storing data transmitted from the plurality of subsystems (100 to 102) and transmitting data according to an event occurring in the building integrated management system (150); Consists of a remote building integrated management system 170 to control from an external remote location using the TCP / IP protocol, the plurality of subsystems (100 to 102) are each a plurality of direct to collect the data at the control point and transmit to the upper Digital controllers 110-118; A plurality of gateways (120 to 122) for transmitting position information of data transmitted from the plurality of direct digital controllers (110 to 118) through a dedicated communication line (2) to upper positions, respectively; Regardless of whether or not the conversion unit converts to the TCP / IP protocol, the middleware modules 140 to 142 for data communication and command delivery with scalable data are embedded to store data transmitted from the gateways 120 to 122. The building integrated management system 150, which is an upper system, is configured as the subsystem servers 130 to 132 which are converted into desired valid data and transmitted.

The middleware modules 140 to 142 each include a middleware server unit 143 which performs a unique function of the system as shown in FIG. 3; A middleware header unit 144 having information on a function of the middleware server unit 143; The middleware client unit 155 is configured to select and implement a function required by the system from the function information of the middleware header unit 144, and FIGS. 4 and 5 attached to the operation process according to the present invention configured as described above. It demonstrates in detail with reference.

First, operations of the unique functions of the plurality of subsystems 100 to 102 operate in the same manner as in FIG. 1, but operations of the middleware modules 140 to 142 of the plurality of subsystems 100 to 102 are similar to those of the middleware. Operate in accordance with the Universal Protocol.

First, in the case of the middleware modules 140 to 142 of the respective systems 100 to 102, as shown in FIG. 4, each middleware server unit 143 objectizes the unique functions of each mounted system to the object. If you declare several such systems as objects and define the methods of the objects in each system, the definition of them is specified in the middleware header unit 144.

Therefore, the middleware header unit 145 includes functions in the middleware modules 140 to 142 of the plurality of subsystems 100 to 102, and the middleware client unit 145 is the middleware header unit 144. The functions of the middleware modules of my various systems are used to implement the functions required by those systems.

That is, the middleware modules 140 to 142 in the plurality of subsystems 100 to 102 select an object for the target system for data communication and command transmission, and the function of the object in the middleware header unit 144 is selected. Look up to find out the address and unique function of the object.

The plurality of middleware modules 140 to 142 automatically find an address of a corresponding system according to a middleware protocol corresponding to a corresponding object, respectively, and transmit information on a desired function in the corresponding system.

In addition, the system transmits and receives such information through each of the mounted middleware modules 140 to 142, and then finds the delivered function in the corresponding middleware server unit 143 to perform the function.

For example, the middleware module 140 in the system A of FIG. 4 is the first unique function of the system A and the system B, which are functions designated by the middleware client unit 145 among the functions of each system of the middleware header unit 144. It performs two unique functions, and the middleware modules 141 and 142 in other systems each perform a function designated by the middleware client unit.

In addition, the system equipped with the middleware module may be used as the middleware server unit 143 that performs the corresponding function, or may be used as the middleware client unit 145 that requests the function of another system. The plurality of subsystems 100 to 102 can be controlled and managed through the middleware header unit 143 of the middleware modules 140 to 142 in the subsystems 100 to 102.

As described in detail above, the present invention includes a TCP / IP protocol in each subsystem, including a middleware module that delivers data communication and commands having extensibility regardless of whether a conversion unit is included. It is effective to minimize development and maintenance costs by establishing an integrated system regardless of type.

In addition, the system can be easily expanded by adding new functions only by changing the functions of the middleware module while efficiently performing data communication with each subsystem through the middleware module in any system connected to the TCP / IP protocol. There is.
