A control system includes: a first human detector that detects the presence or absence of a human within a first detection range; a second human detector that has a second detection range that overlaps with the first detection range, and detects the presence or absence of a human within the second detection range; a determiner that has a plurality of determination modes for determining the presence or absence of a human; a transmitter that transmits a control signal to a control target based on a result of determination made by the determiner; and a load that receives the control signal and serves as the control target whose operation mode is switched according to the control signal. The determiner performs operation in a first determination mode for determining the presence or absence of a human based on at least a result of detection performed by the first human detector when the load is in a first operation mode, and performs operation in a second determination mode for determining the presence or absence of a human based on a result of detection performed by the second human detector when the load is in a second operation mode that is different from the first operation mode.

Control system and sensor unit

A sensor control device which controls: a first sensor which detects, based on a captured image, whether a person is present in a first detection range, and detects, for each of regions into which the first detection range is divided, whether a person is present in the region, based on a captured image; and a plurality of second sensors which detect, based on infrared radiation, whether a person is present in respective second detection ranges includes a determiner which matches, for each of the regions, an on or off state of a detection function of the first sensor in the region with an on or off state of a detection function of a second sensor whose second detection range overlaps the region, among the plurality of second sensors, by controlling the first sensor and the plurality of second sensors.

Sensor control device, sensor system, and load control system

A detection device includes: a first sensor which detects, based on a captured image, whether a person is present in a first detection range; a plurality of second sensors which are disposed around the first sensor, and detect, based on infrared radiation, whether a person is present in respective second detection ranges each of which overlaps at least a portion of the first detection range; and at least one hood which blocks part of infrared radiation directed to at least one of the plurality of second sensors, to reduce a non-overlapping portion of a combined detection range of the first detection range of the first sensor and the second detection ranges of the plurality of second sensors, the non-overlapping portion being a portion in which the first detection range and the second detection ranges do not overlap.

Detection device, load control device, and load control system

A sensor control device includes: a determiner which has a first determination mode for determining whether a person is present, based on a result of detection by a first sensor and a result of detection by a second sensor, and a second determination mode for determining whether a person is present, based on a result of detection by the second sensor, wherein the determiner suspends determination as to whether a person is present in the first determination mode, if a brightness change value indicating a change in brightness in a first detection range during a certain time period is greater than a predetermined value in the first determination mode, and determines whether a person is present in the first determination mode, if the brightness change value in the first detection range is less than the predetermined value in the first determination mode.

A load control system includes: an imaging sensor to capture an image of a target space and detect whether or not a human exists in a detection area in the space; and a display terminal including a display unit to display detection area information corresponding to the detection area thereon. The imaging sensor transmits a transmission signal containing area data indicative of the detection area to the transmission control device, and the transmission control device transmits a transmission signal containing the area data and an address of the display terminal to the display terminal, and the display terminal displays the detection area information on the display unit based on the area data.
