LIGHTING CONTROL SYSTEM AND LIGHTING CONTROL METHOD

摘要

The centralized lighting and air conditioning controller controls the light emission of lighting devices using brightness configuration values, and an environmental sensor transmits illuminance measurement values to the centralized lighting and air conditioning controller by wireless communication. The centralized lighting and air conditioning controller receives the illuminance measurement values, and based on the change in the illuminance measurement values and the change in the RSSI when the illuminance measurement values are received, acquires the degree of influence on the environmental sensor by the light from each of the lighting devices, and acquires the unknown or indeterminate position of the environmental sensor based on the degree of influence.

主权项

1. A lighting control system comprising:
a plurality of lighting devices configured to emit light; a control device configured to control the plurality of lighting devices; and a measuring device configured to measure an illumination, wherein the measuring device comprises:
a transmitter configured to transmit a wireless signal indicating an illumination measurement to the control device, the control device comprises:
a receiver configured to receive the wireless signal indicating the illumination measurement from the measuring device; anda position acquirer, and the position acquirer is configured:
to acquire a disturbance generated in an illumination target region, based on a strength of the received wireless signal received by the receiver, and based on a value of the illumination measurement indicated by the wireless signal received by the receiver, using a correspondence relationship between the value of the illumination measurement, a strength of the received signal, and a disturbance preventing acquisition of a position of the measuring device;to acquire an emission pattern for each lighting device of the plurality of lighting devices based on the acquired disturbance using a correspondence relationship between the disturbance, the measurement value, and a pattern of change of each lighting device in order to remove an effect of the disturbance from the received signal intensity;to control the plurality of lighting devices to emit light according to the acquired emission pattern;while the plurality of lighting devices emits the light according to the acquired emission pattern, based on the illumination measurement measured by the measuring device and the emission pattern per the lighting device, to acquire a degree of influence of emission per the lighting device relative to the illumination measurement by the measuring device; andto acquire, based on positions of the plurality of lighting devices and the degree of influence per the lighting device, the position of the measuring device relative to the positions of the plurality of lighting devices.
