BUILDING MANAGEMENT CONTROL SYSTEM WHICH USES STAND-ALONE DIRECT DIGITAL CONTROLLER WITH ANALOG INTEGRATION AND DRIVING TIME INTEGRATION AND METHOD OF DIRECT DIGITAL CONTROLLER

摘要

PURPOSE: An automatic building management control system using a direct digital controller with analog integration and operation integration functions and a method for controlling the direct digital controller are provided to monitor the amount of energy used in real time by obtaining the amount of power and cold and hot water according to time and sections. CONSTITUTION: An input and output unit outputs a control signal and receives a sensor signal. A storage unit(127) stores an operation condition of a control target. A control unit(121) generates a control signal to control the operation of the control target. An operation time adding unit(125) produces the real operation time of the control target. A web service unit(126) forms an operation state of the control target to a web page screen and provides the formed result to a portable terminal. A data input and output unit(123) includes a general input unit. The general input unit includes an input selection unit, an analog to digital converting unit, and a signal selecting unit. A general output unit includes a current converting unit, a voltage converting unit, and an output selecting unit.
