Abstract

A motion sensor network method for lighting in group units by using an infrared communication sensor according to the present invention comprises the steps of: sensing a first motion of a person or a vehicle by means of a first sensor module and turning on one lighting module; implementing infrared communication with another sensor module adjacent to the first sensor module and turning on another lighting module; maintaining the turning-on of the first lighting module and the other lighting module when the first sensor module or the other sensor module senses a second motion of the person or the vehicle; and turning off the first lighting module and the other lighting module when the first sensor module or the other sensor module fails to sense the second motion of the person or the vehicle for a certain time.

Claims

1. A motion sensor network system for lighting in group units using an infrared communication sensor, the motion sensor network system comprising:

a plurality of lighting modules;

a plurality of sensor modules corresponding to the respective lighting modules and for controlling an on/off operation of the lighting modules,

wherein;

the sensor modules control operations of the lighting modules through wireless communication between the sensor modules in group units;

a group unit comprises at least two lighting modules;

outermost sensor modules among the plurality of sensor modules are installed to be tilted at 30°

to 45°

in up and down direction from a center with respect to the ground; and

the sensor modules except the outermost sensor modules are installed to orthogonally face the ground,

wherein;

each of the sensor module comprises;

a printed circuit board;

a pair of wireless receiver; and

two pairs of wireless transceivers, a first pair of the wireless transceivers being disposed on a side of the pair of the wireless receivers and a second pair of the wireless transceivers being disposed on the other side of the pair of the wireless receivers,

wherein;

a first wireless transceiver of each pair of the wireless transceivers is installed to be horizontal to the printed circuit board and a second wireless transceiver of each pair of the wireless transceivers is installed to be tilted at 30°

to 45°

in up direction with respect to the printed circuit board;

the first wireless transceiver wirelessly communicates with the wireless receiver in a case in which a wireless communication between the sensor modules orthogonally facing the ground is performed, and the second wireless transceiver wirelessly communicates with the wireless receiver in a case in which a wireless communication between the sensor module tilted to the ground and the sensor module orthogonally facing the ground is performed.

2. The method according to claim 1, wherein a one-side lighting module is turned on for predetermined time when a motion of a man or a car is detected by a one-side sensor module or is detected by a neighboring another-side sensor module.

3. The method according to claim 2, wherein:

the one-side lighting module is maintained to be turned on for predetermined time in a case in which the one-side sensor module detects the motion of the man or the car or in a case in which the neighboring another-side sensor module detects the motion of the man or the car; and

lighting brightness in the former case and lighting brightness in the latter case are set to be different.

4. The method according to claim 1, further comprising a remote controller for remotely controlling setting and change of the number of the sensor module in the group units via a non-contact method through infrared communication or local area communication with the sensor module.
