Lighting controller, lighting system and configuration method
A lighting system controller for a lighting system having lighting units and sensors which together form a communications network. A new sensor may be added to the network as a new network node. In response to this, a high sensitivity mode is implemented, for assisting the user in testing the new sensor function.
1. A lighting system controller for controlling a networked lighting system comprising one or more lighting units, the lighting system controller arranged for:
enabling addition, by a user, of a sensor as a new network node to the networked lighting system,
receiving sensor information from the sensor, and
providing wireless control signals to the one or more lighting units in dependence upon the received sensor information,
wherein the lighting system controller is further arranged for:
in response to addition of the sensor, temporarily switch from a normal operation mode to a high sensitivity mode for assisting the user in testing the sensor function,
wherein in the high sensitivity mode the lighting system controller is arranged for increasing the frequency of the polling of the sensor such that there is an increased frequency of communications between the lighting system controller and the sensor compared to the frequency of communications in the normal operational mode.
2. A lighting system controller as claimed in claim 1 , wherein in the high sensitivity mode the networked lighting system is arranged for operating with a changed sensor threshold level, and wherein the changed threshold level comprises a reduced hysteresis between sensor output transitions.
3. A lighting system controller as claimed in claim 2 , in which the hysteresis is set to zero.
4. A lighting system controller as claimed in claim 1 , wherein in the high sensitivity mode the networked lighting system is arranged for operating with a changed sensor threshold, and wherein the changed threshold level comprises a reduced delay between sensor output transitions.
5. A lighting system controller as claimed in claim 4 , in which the delay is set to zero.
6. A lighting system controller as claimed in claim 1 , wherein the high sensitivity mode ends after a fixed time period or wherein the high sensitivity mode ends based on receiving a user input.
7. A lighting system comprising:
a lighting system controller as claimed in claim 1 ;
one or more lighting units; and
one or more sensors, wherein the one or more lighting units, the one or more sensors and the lighting system controller form a network.
8. A lighting system as claimed in claim 7 , comprising an output device for assisting the user in testing the sensor function, wherein the output device comprises:
at least one of the one or more lighting units; and/or
a portable display device for providing performance information to the user; and/or
a speaker.
9. A method of operating a lighting system controller for controlling a networked lighting system comprising one or more lighting units, the method comprising:
detecting the addition of a sensor, by a user, as a new network node to the networked lighting system;
receiving sensor information from the sensor,
providing wireless control signals to the one or more lighting units in dependence upon the received sensor information, and
in response to addition of the sensor, temporarily switch from a normal operation mode to a high sensitivity mode for assisting the user in testing the sensor function,
wherein in the high sensitivity mode the networked lighting system increases the frequency of the polling of the sensor such that there is an increased frequency of communications between the lighting system controller and the sensor compared to the frequency of communications in the normal operational mode.
10. A method as claimed in claim 9 , wherein in the high sensitivity mode the networked lighting system operates with a changed sensor threshold level, and wherein the changed threshold level comprises a reduced hysteresis between sensor output transitions.
11. A method as claimed in claim 9 , wherein in the high sensitivity mode the networked lighting system operates with a changed sensor threshold level, and wherein the changed threshold level comprises a reduced delay between sensor output transitions.
12. A method as claimed in claim 9 , wherein the high sensitivity mode ends after a fixed time period or wherein the high sensitivity mode ends based on receiving a user input.
13. A computer program product comprising code stored on a non-transitory computer readable storage medium and configured when executed to implement the method of claim 9 .
