Abstract

A facilities control device includes control point acquiring means for acquiring control point data for monitoring and controlling the operation of the facilities equipment; monitoring interval setting means for setting monitoring intervals depending on the types of the control point data; control point data monitoring means for comparing the previous-cycle value and the present-cycle value of control point data to monitor whether or not there has been a change within the monitoring interval; and monitoring result notifying means for providing notification in the event that that there is a determination that there has been no change in control point data within the monitoring interval.

Claims

1. A facilities control device for monitoring the operation of equipment within a facility, comprising:

a control point data acquiring device acquiring, at predetermined intervals, control point data for monitoring and controlling the operation of equipment;

a control point data monitoring device comparing the previous-cycle value and the present-cycle value for the control point data acquired by the control point data acquiring device, and for monitoring whether or not there is a change over a specific monitoring interval; and

a monitoring result notifying device providing notification when there is a determination by the control point data monitoring device that there has been no change in control point data within the monitoring interval.

2. The facilities control device as set forth in claim 1, further comprising:

a monitoring interval setting device setting a monitoring interval for each type of control point data.

3. The facilities control device as set forth in claim 1, further comprising:

a monitoring result notifying device displaying, on a monitoring screen, information for each equipment, ranked in order by the length of time over which the previous-cycle values and the present-cycle value have matched.

4. A facilities control method for monitoring the operation of equipment within a facility, comprising the steps of:

a control point data acquiring step, acquiring, at predetermined intervals, control point data for monitoring and controlling the operation of equipment;

a control point data monitoring step, comparing the previous-cycle value and the present-cycle value for the control point data acquired in the control point data acquiring step, and for monitoring whether or not there is a change over a specific monitoring interval; and

a monitoring result notifying step, providing notification when there is a determination in the control point data monitoring step that there has been no change in control point data within the monitoring interval.

5. The facilities monitoring device as set forth in claim 4, further comprising the step of:

a monitoring interval setting step, setting a monitoring interval for each type of control point data;

wherein, in the control point data monitoring step, monitoring is performed as to whether or not there is a change in the monitoring point data within the monitoring interval set in the monitoring interval setting step.

6. The facilities monitoring device as set forth in claim 4, further comprising the step of:

a monitoring result displaying step comprising the steps of;

receiving a notification from the monitoring result notifying step, and

displaying information for each equipment on a monitoring screen, ranked in order by the length of time over which the previous-cycle values and the present value have matched.
