Abstract

Device for temperature recording and display, especially the exterior temperature, uses a movement indicator (1) to measure a temperature-representative value which is then wirelessly transmitted over a transmitter (3) to a temperature display device (7) with an associated receiver.

Description

The The invention relates to a device for detection and display the temperature, in particular the outside temperature according to the generic term of claim 1.

at home Weather stations, it is well known, a separate temperature sensor for detection the outside temperature to equip with a radio transmitter, which at periodic intervals one of the current outside temperature corresponding radio telegram to an inside of the house Weather station with radio receiver emits. The weather station has a display for displaying the outside temperature and other measured value signals, such as internal temperature, humidity, Air pressure and the like.

Of the Invention is based on the object, a cost-effective device for recording and displaying the temperature, in particular outside temperature, specify.

These The object is achieved in conjunction with the features of the preamble according to the invention solved specified in the characterizing part of claim 1 features.

• • zur Anzeige der aktuellen Außentemperatur,
• • zur Erzeugung einer Frostwarnung,
• • zur Messwertsignalerfassung einer Wetterstation oder
• • zur außentemperaturgesteuerten Regelung einer Heizungsanlage

ein zusätzlicher Außentemperaturfühler entbehrlich ist. Vorteilhaft wird der zur korrekten Funktionsweise eines Bewegungsmelders ohnehin erfasste Temperaturwert auch für diese weiteren (nicht in unmittelbarem Zusammenhang mit der Nutzung des Bewegungsmelders stehenden) Anwendungen verwendet.The achievable with the present invention consist in particular that

• • to display the current outside temperature,
• • to generate a frost warning,
• • for the measured value signal acquisition of a weather station or
• • for the outside temperature controlled control of a heating system

an additional outside temperature sensor is dispensable. Advantageously, the temperature value already detected for the correct functioning of a motion detector is also used for these other applications (which are not directly related to the use of the motion detector).

Further Advantages will be apparent from the following description.

advantageous Embodiments of the invention are characterized in the subclaims.

The Invention will be described below with reference to the drawing Embodiments explained. It demonstrate:

1 an exemplary embodiment for a transmission of the temperature measured value signal between a motion detector and an actuator,

2 . 3 two exemplary embodiments for a transmission of the temperature measured value signal between a motion detector and a bus system,

4 an embodiment of the transmission of the temperature measurement signal between a motion detector and a weather station.

In 1 an exemplary embodiment for a transmission of the temperature measured value signal between a motion detector and an actuator is shown. It is an outdoor motion detector 1 with adjustment device 2 (for setting the twilight setting or brightness switching threshold and switch-off delay or delay time) and transmitter (preferably radio transmitter) 3 to recognize. An actor 4 with mains connection 5 and receiver (preferably radio receiver) 6 controls a connected lighting fixture 9 - For example, installed in front of a house front door outdoor light - depending on the wireless connection transmitter 3 - Receiver 6 received command signals BS.

For detection of a moving body in the detection area, the motion detector 1 a pyroelectric infrared sensor (PIR motion detector). The range of a motion detector can fluctuate very much in changing conditions. The reasons for this are mainly in the prevailing ambient temperature. Therefore, motion detectors are provided with an automatic range stabilization, in which, depending on the environmental conditions, in particular the ambient temperature, the program of a microprocessor controls the electronic gain and thus reduces fluctuations in the range and coverage to a minimum. For the evaluation, it is necessary to detect the current temperature and to forward the evaluation circuit.

In addition, the temperature measurement value TM determined for the automatic range stabilization is likewise transmitted via the wireless connection transmitter 3 - Receiver 6 transmitted and by means of a temperature display device 7 of the actor 4 brought to the display. Optionally, the temperature indicator is 7 at the actuator 4 or on the associated lighting fixture 9 assembled. If the current temperature measured value TM falls below a critical value, then a frost warning light is additionally emitted 8th driven. This measure is particularly advantageous in an outdoor light installed in front of a house front door as a lighting fixture 9 because one is House leaving person is always up to date about a possible risk of ice risk is informed.

In 2 a first embodiment for a transmission of the temperature measurement signal between a motion detector and a bus system is shown. It is again an outdoor installed motion detector 1 with adjustment device 2 and transmitter 3 to recognize. The command signals of the transmitter 3 arrive at a bus system 10 connected receiver (preferably radio receiver) 13 , To the bus system 10 are among other things an actor 11 with mains connection 23 and connected lighting fixture 12 , a heating control / control device 16 and a temperature display device 17 connected.

The actor 11 is via the connection transmitter 3 - Receiver 13 - Bus system 10 from the command signals BS of the motion detector 1 driven. In addition, the actuator points 11 or the associated lighting fixture 12 a temperature display device 14 and a frost warning light 15 on, so that in itself for the automatic range stabilization determined and over the connection transmitter 3 - Receiver 13 - Bus system 10 additionally transmitted temperature measured value TM at the actuator 11 or lighting fixture 12 brought to the display and a black ice warning can be issued.

The bus system 10 supplied temperature measured value TM also serves as the outside temperature measured value for the heating control / control device 16 , so that advantageously an additional heater outside temperature sensor is unnecessary. Furthermore, the bus system 10 supplied temperature measured value TM at one (or more) temperature display devices) 17 within a house for display.

Generally, that of the motion detector 1 continuously determined temperature measured value TM are transmitted periodically (at specified time intervals) or as required (request) to the actuator or the bus system.

In 3 a second embodiment of a transmission of the temperature measurement signal between a motion detector and a bus system is shown, wherein a central office 24 of the bus system request signals AS to the motion detector 1 whereupon the motion detector sends the current temperature measured value TM to the bus system 10 transmitted. Accordingly, for bidirectional communication between motion detectors 1 and bus system 10 Transmitter / receiver (preferably radio transmitter / receiver) 18 respectively. 19 in place of a transmitter 3 or recipient 6 required. The further arrangement is as below 2 described.

In 4 an embodiment for the transmission of the temperature measurement signal between a motion detector and a weather station is shown. It is the motion detector 1 with adjustment device 2 and transmitter 3 to recognize, with the transmitter 3 on the one hand command signals BS to the receiver 6 of the actor 4 with connected lighting fixture 9 as well as on the other hand for the automatic range stabilization determined temperature measured value signals TM to a receiver (preferably radio receiver) 22 a weather station located inside the house 20 with temperature indicator 21 emits.
