Description

The The invention relates to a wireless motion detector / actuator system with at least one motion detector, which wirelessly via a Transmitter having at least one receiver and at least a lighting fixture controlling actuator communicates.

From the US 2003 00 20 611 A1 a wireless motion detector / actuator system is known with at least one motion detector which communicates wirelessly via a transmitter with at least one actuator having a receiver and activating at least one lighting fixture. The system has a possibility for monitoring the system state in that the operating status of the actuator can be checked by means of a signal emitted by a remote control unit and received by the actuator. A display device of the actuator is used to indicate which motion detector has sent a signal to the actuator as a result of a detected movement.

From the DE 38 03 277 A1 For example, there is known an infrared radiation receiver which is particularly suitable for motion detectors and which contains a power source and a transmitter (radio transmitter or infrared transmitter) which is controlled by the signals of the radiation receiver and in turn emits wireless control signals to a remote signal receiver. The device is independent of a supply network, has a battery (accumulator) and can be used anywhere in a room to influence different circuits.

From the DE 101 50 128 C2 a wireless sensor system is known, which has a solar cell with downstream energy storage and which by means of a transmission telegram information wirelessly -. B. via radio - to a mains-connected reception and evaluation - z. B. a lighting control - passes. The sensor system can be used to determine the position or to determine an illuminance. The state of charge of the energy storage is monitored. There is a timer circuit which can be triggered as a function of a voltage level of the energy store and which activates the sensor system for transmitting at least one transmission telegram after a certain time interval in order to thus provide an improved status inquiry. The data transfer takes place at fixed or variable intervals even without movement of the monitored devices.

Generally A motion detector is in a daytime sleep during the day. Only after a given light value (depending on the set Twilight setting) is reached, the motion detector is in active Operating condition. Is during the dusk In the morning or in the evening a motion detector inactive, it is for one User can not directly see if the motion detector is defective or is the motion detector due to still sufficient Brightness is in daytime sleep. The same is true in general known wireless motion / actuator systems no possibilities to recognize in good time a defect of a system component.

This second embodiment according to 2 In addition to the monitoring of the activity state of the motion detector / actuator system explained in detail above, it is additionally possible to monitor the system component state:

• 1. The monitoring devices 18 - 20 monitor the correct functioning of the motion detectors 1 . 4 . 7 For example, to detect hardware errors. For example, these monitoring devices can check the detected temperatures or detected brightness values for plausibility. Anyone who recognizes the interference, so there is a transmission of corresponding signaling signals SA to the actuator, at For example, "sensor module defective".
• 2. The monitoring devices 18 - 20 measure the current voltage of the batteries or accumulators. Optionally, a transmission of a signaling signal SA "battery or accumulator heavily discharged" to timely indicate a required battery change or required battery charging. In this way it is prevented that, for example, a dead battery can be mistakenly interpreted as a device defect.
• 3. The monitoring devices 18 - 20 Check if the lighting fixture 17 of the actor 10 is functional or defective. Optionally, there is a transmission of a message signal SA "lighting body defective" to the actuator 10 , Details are under the 3 and 4 explained.
• 4. The monitoring devices 18 - 20 Check the condition - especially the degree of soiling - of the solar panel. Optionally, a transmission of a message signal SA "clean solar panel" to the actuator 10 , Details are under 4 explained.

In 3 is a first way to check the lighting fixture 17 of the actor 10 For functionality see above 3 , It is assumed that the coverage area 27 of the motion detector 1 and the lighting area 28 of the lighting fixture 17 cover in sections and an overlap area 29 form. digit 30 denotes a path to be monitored. Sets the sensor module (infrared sensor) of the motion detector 1 within a predetermined period of time TR after sending the command signal "Switching on the lighting fixture" a significant increase in the detection range 27 measured brightness value, so this is interpreted as an indication that the lighting fixture 17 is functional.

In 4 is a second way to check the lighting fixture 17 of the actor 10 For functionality see above 2 , This involves the use of a solar panel 24 / accumulator 21 for power generation / energy storage for the motion detector 1 provided. Furthermore, it is assumed that the solar panel 24 partly in the lighting area 28 of the lighting fixture 17 is arranged. Represents the motion detector 1 over the solar panel 24 including accumulator 21 and monitoring device 18 within a predetermined period of time TR after sending the command signal BS "switch on lighting fixture" an increase in the detection area 28 measured brightness value - which of course has a significant increase in solar cell voltage and energy production result - so this is interpreted as an indication that the lighting fixture 17 is functional.

A third way to check the lighting fixture 17 of the actor 10 on functionality is the lighting fixture 17 to undergo a continuity test, which is expedient by the monitoring device 31 of the actor 10 he follows. If the lighting fixture 17 is defective, this is directly through the display device 13 brought to the display.

As an alternative to the above explanations, it is of course also possible for the aforementioned plausibility checks to be carried out by the monitoring device with respect to temperatures and / or transmitted brightness values detected by the motion detector and transmitted to the actuator 31 of the actor 10 be made.

4 further shows the possibility of checking the state - in particular the degree of contamination - the solar panel - see the preceding paragraph 4 , It is again assumed that the solar panel 24 partly in the lighting area 28 of the lighting fixture 17 is arranged. As already stated above, the motion detector 1 over the solar panel 24 including accumulator 21 and monitoring device 18 within a predetermined period of time TR after sending the command signal BS "switch on the lighting fixture" an increase ΔH in the detection area 28 measured brightness value, as that on the solar panel 24 Light emitted by the lighting unit results in an increase in the solar cell voltage and thus in the generation of energy. It is understandable that ΔH with clean solar panel 24 larger than with a dirty solar panel 24 will be, ie .DELTA.H represents a meaningful size with respect to the degree of contamination.

Another way to check the condition - especially the degree of soiling - of the solar panel is that the verification by comparing the solar panel 24 detected signals with the signals of a brightness sensor of the motion detector 1 be compared. In the new condition, these signals have a certain signal relationship, which can be stored. If the currently detected signal relationship deviates significantly from the stored signal relationship, this is interpreted as contamination of the solar panel.

at the above explained embodiments It is assumed that the overrun time / off delay is exceeded via the Setting device of the motion is specified. alternative this is also possible the delay time / switch-off delay at the actuator. In this case will be in normal operation in the wirelessly transmitted Signal (radio protocol) from the motion detector (sensor) to the actuator only a pure "ON command" (command "switch on the lighting fixture").
