Description

A controller, method, and computer program for controlling multiple facilities provided in a building {CONTROLLER, METHOD AND COMPUTER PROGRAM FOR CONTROLLING EQUIPMENTS INSTALLED IN BUILDING}

The present invention relates to a controller, a method, and a computer program for controlling a plurality of facilities provided in a building.

Building facilities are mostly controlled by control devices such as PLC (Programmable Logic Controller) or DDC (Direct Digital Controller). The input/output module is integrally mounted in such a control device. However, since the input/output module mounted in the control device provides a limited number of ports, if the number of sensors (sensors installed in the facility) connected to the control device increases, the number of control devices must also increase. Accordingly, there is a problem in that the purchase cost of the control device increases, and an additional space is required for the increased control device.

In addition, the conventional building automatic control system takes a lot of time because the facility manager of the building directly connects the control device and a plurality of facilities. In addition, in the conventional building automatic control system, it is difficult to provide a cloud web service because the number of control devices increases as facilities increase.

Referring to FIG. 1, the facility control system may include a controller 100, a remote server 110, a plurality of input/output modules 120, 122, 124, and a plurality of facilities 130, 132, 134. However, since the facility control system of FIG. 1 is only an embodiment of the present invention, the present invention is not limitedly interpreted through FIG. 1, and may be configured differently from FIG. 1 according to various embodiments of the present invention.

In general, each component of the facility control system of FIG. 1 is connected through a network (not shown). A network refers to a connection structure that enables information exchange between nodes such as terminals and servers, and is a local area network (LAN), a wide area network (WAN), and the Internet (WWW: World). Wide Web), wired and wireless data communication networks, telephone networks, wired and wireless television networks, etc. Examples of wireless data networks include 3G, 4G, 5G, 3GPP (3rd Generation Partnership Project), LTE (Long Term Evolution), WIMAX (World Interoperability for Microwave Access), Wi-Fi, Bluetooth communication, infrared communication, and ultrasound.

The controller 100 may map and control a plurality of facilities provided in a building to a plurality of input/output modules 120, 122, and 124. Here, the plurality of facilities are, for example, heat source equipment (e.g., refrigerators, boilers), mechanical equipment (e.g., air conditioners, heat exchangers), lighting equipment, power equipment (e.g., switchboard), demand management equipment, water supply wide area equipment ( For example, gas, water) and the like may be included.

Specifically, the controller 100 may communicate with the external server 110 and receive an input/output mapping table from the external server 110. Here, the input/output mapping table includes information on each of the plurality of input/output modules 120, 122, 124 connected wirelessly or wired to the controller 100, and a facility connected to the input/output modules 120, 122, 124.
