Kind Code:
A1
Abstract:
The objective of the present invention is to provide a communication system, a control apparatus, a control method, and a program with which it is possible to acquire highly reliable sensor data at low cost. A communication system 301 according to the present invention comprises a control apparatus 10, a plurality of lighting appliances 20, and an IoT device 30. The lighting appliances 20 output modulated light that has been modulated, the IoT device 30 receives each modulated light, sets information acquired from each modulated light as metadata Dm, and transmits the metadata Dm and collected sensing data Ds to the control apparatus 10 in association with one another, and the control apparatus 10 controls the generation and output of the modulated light with respect to the lighting appliances 20, estimates a position of the IoT device 30 from the metadata Dm, and stores the position of the IoT device 30 and the sensing data Ds in association with one another.
