Information presentation device

An information presentation device, comprising:

• a request reception unit which receives a picture request which includes an picture identification (ID) which specifies a request picture from an external program;
• a facility information database (DB) which stores a point ID which is information of external equipment connected to a management device and a value of the point;
• a picture information DB which stores the point ID which is stored in the facility information DB and a picture ID which specifies a picture which displays the value of the point specified by the point ID corresponding to each other;
• a collection time DB which stores a collection time which is required to collect the value of the point corresponded to the picture ID;
• an information collection unit which calculates a request interval when receiving the picture request signal from the request reception unit, a request interval by subtracting a previous request reception time from the request reception time which is a time at which the picture request has been received, which calculates the next request reception time by adding the request interval to the request reception time, which calculates a pre-reading starting time by subtracting the collection time from the next request reception time, and which directs the management device to start the collection of the value of the point when the pre-reading starting time comes;
• and
• a picture generation unit which obtains the value of the point from the facility information DB and generates the picture to transmit the picture from the values of the obtained point when receiving the picture request from the request reception unit.
