Abstract

An object detection system 1 includes a sensor section 10 configured to detect an object within a detection area A; and an adjuster (remote controller) 20 configured to interactively communicate with the sensor section 10. The sensor section 10 includes a driving machine 6 configured to adjust the detection area A. The adjuster 20 includes a transmission unit 13 configured to transmit, to the sensor section 10, a setting signal for setting an operating condition of the sensor section 10 including adjustment of the detection area A by the driving machine 6; and an adjustment notification unit 23 configured to receive a completion signal of operating condition setting from the sensor section 10 and subsequently give notification of the operating condition, setting of which has been completed.

Claims

1. An object detection system comprising:

a sensor section configured to detect an object within a detection area; and

an adjuster configured to interactively communicate with the sensor section,

wherein the sensor section includes a driving machine configured to adjust the detection area, and

wherein the adjuster includes;

a transmission unit configured to transmit, to the sensor section, a setting signal for setting an operating condition of the sensor section including adjustment of the detection area by the driving machine; and

an adjustment notification unit configured to receive a completion signal of operating condition setting from the sensor section and subsequently give notification of the operating condition, setting of which has been completed.

2. The object detection system as claimed in claim 1, wherein when installation position information of a target sensor unit intended for the operating condition setting and setting information of a detection area are inputted to the adjuster, the setting signal is transmitted to the target sensor unit, and a detection area angle adjustment mechanism is caused to operate by driving of the driving machine, thereby automatically setting the detection area.

3. The object detection system as claimed in claim 1, wherein the adjuster causes the adjustment notification unit to generate a sound, a color, or light that gives notification of reception of the completion signal.

4. The object detection system as claimed in claim 1, wherein the sensor section includes an operation confirmation unit configured to confirm an operation of the driving machine for a short time period at arbitrary intervals.

5. The object detection system as claimed in claim 1, wherein when an ambient temperature is lower than an operating temperature of the driving machine, the sensor section is preliminarily powered on, and if the ambient temperature has not reached the operating temperature of the driving machine in setting the detection area, the adjustment notification unit of the adjuster is caused to give notification of setting standby.

6. The object detection system as claimed in claim 1, wherein angle adjustment of the detection area is performed such that an angle of the detection area is set at an angle designated by the adjuster on the basis of a detection ray reference angle determined on the basis of an irradiation state of detection rays from the sensor section.
