1. An air-conditioning control device to control operation of a plurality of air conditioners, the air-conditioning control device comprising:
air conditioner management circuitry to manage operating states of the air conditioners;
image analysis circuitry to analyze image information obtained from an image sensor, to ascertain a person in each of air conditioning areas, the air conditioners providing controlled air conditioning for the air conditioning areas, and to identify a position where a person is present from a position of a block, the block being obtained by dividing each of the air conditioning areas into a plurality of blocks;
air-conditioning communication line connectors respectively for the air conditioning areas, the air-conditioning communication line connectors being connectable with air-conditioning communication lines, the air conditioners being connected to the air-conditioning communication lines;
air-conditioning communication line connection determination circuitry capable of determining whether or not each of the air conditioners is connected to a corresponding one of the air-conditioning communication line connectors via a corresponding one of the air-conditioning communication lines; and
an air-conditioning controller to provide, on a basis of number of persons in each of the air conditioning areas, air conditioning area-specific operation control for the air conditioners connected to the air-conditioning communication line connectors via the air-conditioning communication lines.
