Description

Systems and methods for testing sensor units
Field of the Invention
The present invention concerns systems and methods for testing sensor units, particularly presence detectors. More particularly, but not exclusively, the invention concerns systems comprising remote devices that indicate the detection of a presence by a sensor unit.
Background of the Invention
Building lighting and security systems often include sensor units for detecting a presence, e.g. of an individual entering a room, upon which lighting and/or alarms of the system is activated. Once a sensor unit has been configured using a commissioning tool (a hand-held control device used for configuration and adjustment of the components of a system such as a building lighting and/or security system) / it is desirable to verify the operation of the sensor unit by performing a walk test". A walk test is performed by the sensor unit being put into test mode, and then an individual moving around the periphery of the area covered by sensor unit while observing the operation of the sensor unit. Traditionally, the operation of the sensor unit is ascertained by observing a light-emitting diode (LED) built into the sensor unit, which is activated when the sensor unit detects a presence.
However, it is a disadvantage of such systems that it can be difficult to observe the LED at the same time as moving around the periphery of the area oovered by sensor unit, partioularly when trying to move in a "natural" manner. Observation can be particularly difficult when the sensor unit is a wide-viewing detector for an area with low ceiling height. Difficulty in observing the LED has been exacerbated by recent fashions in design, for which it is desirable to keep the profile of the sensor unit as shallow as possible (for example sensors units may be recessed into the ceiling) , with the LED being mounted behind, or in proximity to, the sensor element of the sensor unit.
The present invention seeks to solve and/or mitigate the above-mentioned problems. Alternatively and/or additionally, the present invention seeks to provide improved systems and methods for testing presence detectors.
Summary of the Invention
In accordance with a first aspect of the invention there is provided a system for testing a presence detector, comprising: a sensor unit mounted on a surface of a building, the sensor unit comprising a sensor element for detecting a presence; a remote device arranged to communicate with the sensor unit using wireless signals, the remote device comprising an indicator; wherein the sensor unit is arranged to operate in a test mode in which, in response to the detection of a presence by the sensor element of the sensor unit, it sends a detect signal to the remote device; and wherein the remote device is arranged, in response to receiving a detect signal from the sensor unit, to activate the indicator to indicate the detection of a presence.
The senscr unit may be mcunted on the ceiling or wall of a room, or an extericr wall of a building, for example.
By having the sensor unit communicate with the remote device, and the remote device comprise an indicator that is activated when the sensor unit detects a presence, a user testing the system can ascertain whether the sensor unit has detected a presence or not by observing the indicator of the remote device, rather than having to try to observe an indicator comprised in the sensor unit itself. As the remote device and sensor unit communicate using wireless signals, when used for testing the remote device can be positioned anywhere that it can be easily observed by the user doing the testing. Further, the indicator can be positioned on the remote device so that it can be easily observed by the user, which would be disadvantageous for the sensor unit due to the design considerations that apply to them (in other words that they are unobtrusive and not unattractive) Advantageously, the remote device is a commissioning tool for the sensor unit. This means that the commissioning tool can be conveniently used both for configuring and testing the sensor unit, and an additional remote device for testing is not required. Preferably, the commissioning tool is hand-held.
Preferably, the remote device is arranged to send a test-mode signal to the sensor unit; and the sensor unit is arranged, in response to receiving a test-mode signal from the remote unit, to operate in the test mode. The remote device may also be arranged to send a normal-mode signal to the sensor unit; and the sensor unit arranged, in response to receiving a normal-mode signal from the remote unit, to operate in normal mode, in other words the normal mode of operation of the sensor unit.
Preferably, the sensor element is an infra-red sensor (for example a PIR sensor element) . However, the sensor element may be any other type of sensor element that is suitable for detecting the occupancy of the room, such as an ultrasound sensor, or a camera with appropriate movement-detection functionality.
Preferably, the sensor unit and remote device are arranged to communicate using infra-red signals. However, any other type of suitable wireless signals may be used, for example ultrasound signals, radio-freguenoy (RE') signals or the like.
The indicator may comprise a light-emitting device, such as a light-emitting diode (LED) . Alternatively and/or additionally, the indicator may comprise an audio device, such as a speaker that emits a beeping sound to indicate that the sensor unit has detected a presence, or a buzzer.
Alternatively and/or additionally, the indicator may comprise a display screen of the device, such as the display screen used for general use of the remote device when it is a commissioning tool for the sensor unit. The indicator may provide an indication that a presence has been detected for the entire time it is detected, for example by providing a continuous light and/or sound. Alternatively, the indicator may indicate only when a presence is initially detected.
Alternatively and/or as well as providing a simple indication of the detection of a presence (such as an LED lighting up or a beep sound) , the remote device may indicate using the indicator detailed information from the sensor unit, detection, such as the strength of the signal detected by the sensor element. The information may be indicated using numbers, graphs or the like. An oscilloscope-type display may be provided showing the change in the analogue signal generated by the sensor element due to detected movement along with background noise. The skilled person will appreciate that any other suitable indicator device and style of indication by the indicator device could be used.
Preferably, the remote device is shaped and configured so that the indicator is easily observed when the remote device is positioned on a flat surface such as the floor of a room. The remote device may comprise a stand to facilitate this.
The sensor unit is preferably part of a lighting control system. The sensor unit preferably comprises a controller for controlling lighting in dependence on the detection of a presence/absence.
The sensor unit may further comprises a photosensor sensor element for detecting light level. In test mode the sensor unit may send a light level signal to the remote device. The remote device may be arranged, in response to receiving a light level signal from the sensor unit, to indicate the light level. Such an arrangement is especially beneficial because a user testing the system can obtain an indication of the light level being sensed by the sensor, without needing to be in proximity to the sensor unit. This reduces the chance of the user causing any changes to the light level during testing (for example by casting a shadow and/or increasing the reflected light received by the photosensor sensor element) In accordance with a second aspect of the invention there is provided a method of testing a presence detector comprising a sensor unit mounted on a surface of a building, the sensor unit comprising a sensor element for detecting a presence, using a remote device arranged to communicate with the sensor unit using wireless signals, the remote device comprising an indicator, the method comprising the steps of: a) the sensor unit, in response to the detection of a presence by the sensor element of the sensor unit, sending a detect signal to the remote device; b) the remote device, in response to receiving the detect signal from the sensor unit, activating the indicator to indicate the detection of a presence.
Advantageously, the remote device is a commissioning tool for the sensor unit.
Preferably, the method further comprises the steps performed prior to step a) of: zi) the remote device sending a test-mode signal to the sensor unit; and z2) the sensor unit, in response to receiving the test-mode signal from the remote unit, operating in the test mode.
Preferably, the sensor element is an infra-red sensor.

Description of the Drawings
Embodiments of the present invention will now be described by way of example only with reference to the accompanying schematic drawings of which: Figure 1 shows a system for testing a presence detector in accordance with an embodiment of the invention; Figure 2 is a flowchart showing the operation of the system of Figure 1 when testing is initiated; Figure 3 is a flowchart showing the operation of the system when testing is in progress; and Figure 4 is a flowchart showing the operation of the system of Figure 1 when testing is finished.
Detailed Description
A system for testing a presence detector in accordance with an embodiment of the invention is shown in Figure 1. The system comprises a sensor unit 110, which is mounted on the ceiling 100 of a room. The sensor unit 110 comprises an infra-red sensor element 111, which is intended to detect the presence of individuals within a detection area defined -11 -by a circle 101 on the floor of the room beneath the sensor unit 110. The sensor unit is in a lighting control system.
In accordance with known lighting control systems, the sensor unit comprises a controller (not shown) for controlling the lighting in the room (not shown) in response to its detection of the presence/absence of persons in the room.
The sensor unit 110 of the first embodiment of the invention also comprises an infra-red communication unit (not shown in Figure 1), with which it can communicate by sending and receiving infra-red signals.
The system further comprises a hand-held commissioning tool 120, which is positioned on the floor of the room in the centre of the circle 101 that defines the detection area for the sensor unit 110. The commissioning tool 120 comprises an LED indicator 121. Ihe commissioning tool 120 also comprises an infra-red communication unit (not shown in Figure 1) with which it can communicate by sending and receiving infra-red signals, and in particular with which it can communicate with the sensor unit 110.
The use and operation of the system is now described with reference to Figures 2 to 4.
Figure 2 is a flow chart showing the operation of the system when testing is initiated. Initiaily, a user wiil be holding the commissioning tool 120 in their hand, and may for example have just finished using it to configure the sensor unit. Io initiate the testing process, first the user instructs the commissioning tool 120 that test mode is to begin (step 1), for example by choosing an appropriate menu option on the commissioning tool 120. In response, the -12 -commissioning tool 120 sends a test-mode signai to the sensor unit 110 (step 2) using its infra-red communication unit, to instruct the sensor unit 110 to enter test mode.
On receiving the test-mode signal using its infra-red communication unit, the sensor unit 110 enters test mode (step 3) . The operation of the sensor unit 110 in test mode is described in more detail below. The user then places the commissioning tool 120 in the centre of the circle 101 that defines the detection area (step 4) , to give the arrangement shown in Figure 1.
Figure 3 is a flow chart showing the operation of the system when testing is in progress. To test the system, the user walks the periphery of the circle 101 defining the detection area (step 11) . In particular, the user will move into and out of the detection area, and will wish to know when they are detected by the sensor unit 110 so that they know if it is operating correctly. (For example, they will want to know if it is erroneously falling to detect them when they are within the detection area.) If the sensor unit 110 detects the user using its sensor element 111 (step 12), it sends a detect signal to the commissioning tool 120 (step 13) using its infra-red communication unit. On receiving the detect signal using its infra-red communication unit, the commissioning tool 120 activates its LED indicator 121 (step 14), in other words the LED indicator 121 is lit.
In this way, the user can ascertain when the sensor unit 110 has detected a presence by observing when the LED indicator 121 of the commissioning tool 120 is activated.
(Similarly, they can ascertain when sensor unit 110 has not -13 -detected a presence by observing when the LED indicator 121 of the commissioning tool 120 is inactive) . As the commissioning tool 120 is placed in an easily observed position (in other words on the floor in the centre of the circle 101), and the LED indicator 121 is easily observed on the device itself, detection of a presence can be much more easily observed than would be possible using an LED mounted in the sensor unit 110 itself.
Figure 4 is a flow chart showing the operation of the system when testing is finished. Initially, a user will pick up the commissioning tool 120 from its position on the floor, and instruct it to leave test mode is to begin (step 21), again for example by choosing an appropriate menu option. In response, the commissioning tool 120 sends a normal-mode signal to the sensor unit 110 (step 22), to instruct the sensor unit 110 to leave test mode. On receiving the normal-mode signal, the sensor unit 110 enters normal mode (step 3), in other words its normal mode of operation. The user may then make further changes to the configuration of the sensor unit 110 with the commissioning tool 120, based on the results of the testing; for example the testing may have revealed that the sensitivity of the sensor unit 110 needs to be increased as it was failing to detect the user in certain positions within the detection area. Once any configuration changes have been made, the new configuration can be tested by repeating the process of Figures 2 to 4.
Whilst the present invention has been described and illustrated with reference to particular embodiments, it will be appreciated by those of ordinary skill in the art -14 -that the invention lends itself to many different variations not specifically illustrated herein.
