Description

Matrix-Based Integrated Control System The present invention relates to a matrix-based integrated control system, and more specifically, to a matrix-based integrated control system that determines the operating conditions of an output device by referring to a matrix table set based on complex input conditions such as time, date, and season. In various industrial control fields, such as building automation, water treatment facilities, and smart city infrastructure, systems that control output devices like pumps, valves, and HVAC equipment based on environmental information including temperature, humidity, water level, and power consumption are widely utilized. These systems primarily follow a structure that adjusts output in real-time according to sensor input, but they have limitations in reflecting multidimensional control logic based on specific time or seasonal conditions. Since most existing control systems rely on code-based control logic or simple PLC schedule control methods, changing control conditions or reflecting detailed schedules entails complex program modifications. Furthermore, the capability to determine outputs by analyzing complex conditions such as time, date, day of the week, and season in real time is currently lacking. Due to these constraints, maintenance costs increase in public sites or industrial facilities with frequent environmental changes, and the consistency and flexibility of control logic decrease, and problems arise where setting changes are difficult without specialized technicians. In particular, when differential control based on specific conditions such as regular inspection days, holidays, or nighttime is required, existing systems perform only uniform operations according to a fixed schedule, which can lead to energy waste or malfunctions. Therefore, research is required on a matrix-based integrated control system that determines output conditions based on matrix data set by simultaneously considering date, time, and seasonal conditions, allows non-experts to easily manage settings, and enables condition changes without modifying logic.

FIG. 2 is a conceptual diagram illustrating the process of performing matrix-based integrated control according to an embodiment of the present invention. Specific embodiments of the present invention will be described in detail below with reference to the drawings. However, the concept of the present invention is not limited to the presented embodiments. Those skilled in the art who understand the concept of the present invention may easily propose other inventions that are inferior or other embodiments included within the scope of the concept of the present invention by adding, changing, or deleting other components within the same scope of the concept, and such are also to be considered to be included within the scope of the concept of the present invention. Additionally, components with the same function within the scope of the same concept appearing in the drawings of each embodiment are described using the same reference numeral. FIG. 1 is a block diagram illustrating a matrix-based integrated control system according to an embodiment of the present invention, and FIG. 2 is a conceptual diagram illustrating a process of performing matrix-based integrated control according to an embodiment of the present invention. Referring to FIGS. 1 and 2, the matrix-based integrated control system (100) includes an input unit (110), a matrix storage unit (120), a matrix comparison unit (130), and an output control unit (140). The input unit (110) receives input data including at least one of time information, date information, and season information from one or more input devices. More specifically, the input unit (110) periodically receives input data including at least one of the following: time information (e.g., current time, time zone), date information (e.g., month and day, day of the week, whether it is a public holiday), and seasonal information (e.g., classification of spring, summer, autumn, and winter, or determination based on ambient temperature) from various input devices such as a Real Time Clock (RTC), an external calendar linkage system, an environment sensor, and a controller linkage module. This input data is used as a key criterion for determining control conditions and may be composed of complex conditions such as, for example, 'Tuesday, July 1, 2025, 8:00 AM, Summer'. The input unit (110) can automatically determine whether each input data exists within a normal range and the validity of the format or value, and can be configured to transmit a separate warning flag or correction request signal to the upper control logic if an abnormality is detected. In addition, the input unit (110) can also perform a preprocessing function of receiving data from multiple input devices simultaneously and a
