Abstract
Description
Die Erfindung betrifft eine Vorrichtung nach der deutschen Patentanmeldung 196 47 970.3-32.The invention relates to a device according to the German patent application 196 47 970.3-32.
Die Erfindung bezweckt eine weitere Verbesserung der früheren Patentanmeldung.The invention aims to further improve the earlier patent application.
Bei der Vorrichtung nach der früheren Patentanmeldung war die Empfangsfrequenz des Empfängers 433,42 MHz und die Sendefrequenz des Sender 433,92 MHz. Dies kann zu Störungen führen, wenn mehrere Sender auf der freien Frequenz 433,92 sen den. Ferner ist für den Energieverbrauch nicht nur die Frequenz maßgeblich und zwar deshalb, weil die Frequenz die Größe der Antenne bestimmt, die Antennen leistung bestimmt, die Technologie der Bausteine bestimmt, die Größe der Uhr mitbe stimmt usw. Vielmehr ist auch die Betriebsart hierbei wichtig und die Abstimmung der Ströme und Spannungen.In the device according to the earlier patent application, the reception frequency was of the receiver 433.42 MHz and the transmission frequency of the transmitter 433.92 MHz. This can cause interference if several transmitters on the free frequency 433.92 sen the. Furthermore, frequency is not the only decisive factor for energy consumption because the frequency determines the size of the antenna, the antennas performance determines, the technology of the building blocks determines the size of the watch true etc. Rather, the mode of operation is important and the coordination of the Currents and voltages.
Schließlich möchte man ja mehrere Sender empfangen, z. B. einen weiteren Sender, wobei die Senderzahl durchaus 2-stellig werden kann.After all, you want to receive several stations, e.g. B. another transmitter, where the number of stations can be 2 digits.
Gemäß dem kennzeichnenden Teil des Anspruchs 1 macht es nunmehr nichts mehr aus, wenn andere "Vorrichtungen", wie z. B. Garagentore auf der Frequenz 433,92 MHz senden, denn erfindungsgemäß wurden die Sender und Empfänger-Frequenzen ver tauscht. Dies allein reicht aber nicht aus. Vielmehr wurde die Zwischenfrequenz ver schoben und zwar nach plus (+) verschoben und wegen der hier gewählten Differenz zwischen Senderfrequenz und Empfängerfrequenz auf den numerischen Wert von 500 KHz. Seither lag die Zwischenfrequenz bei minus (-) 500 KHz. Insoweit muß auch die Zwischenfrequenzstufe des Empfängers umdimensioniert werden.According to the characterizing part of claim 1, it now does nothing from when other "devices" such as. B. Garage doors on the frequency 433.92 MHz send, because according to the invention the transmitter and receiver frequencies were ver swaps. But this alone is not enough. Rather, the intermediate frequency was ver shifted to plus (+) and because of the difference selected here between transmitter frequency and receiver frequency to the numerical value of 500 kHz. Since then, the intermediate frequency has been minus (-) 500 KHz. To that extent also the intermediate frequency stage of the receiver can be re-dimensioned.
Gemäß Anspruch 2 wird automatisch getastet. Da die Sendezeit kürzer ist als die Empfangszeit, wird in diesem Maße auch weniger Energie verbraucht, so daß die Batterie geschont wird.According to claim 2 is automatically keyed. Because the airtime is shorter than that Reception time, less energy is consumed to this extent, so that Battery is protected.
Stromspannungswerte gemäß dem Anspruch 3 haben sich bei der in der voraufgehenden Patentanmeldung 196 47 970 verwendeten Technologie sehr bewährt.Current voltage values according to claim 3 have in the previous patent application 196 47 970 technology very proven.
Gemäß Anspruch 4 ist die Sendephase gegenüber der Empfangsphase außerordentlich kurz, und dementsprechend sehr hoch ist auch die Energieeinsparung.According to claim 4, the transmission phase is compared to the reception phase extremely short, and accordingly the energy saving is very high.
Zahlenwerte gemäß Anspruch 5 haben sich in der Praxis sehr bewährt.Numerical values according to claim 5 have proven very useful in practice.
Durch die Merkmale des Anspruchs 6 erreicht man, daß man sich an die Anzahl der Sender anpassen kann. Wenn z. B. fünf Sender empfangen, dann wird zeitlich um einen Betrag von T/5 verschoben.Due to the features of claim 6 one achieves that the number of Can adjust transmitter. If e.g. B. receive five transmitters, then time is one Amount shifted from T / 5.
Die Zeichnung zeigt ein bevorzugtes Ausführungsbeispiel der Erfindung in Form von Zeitdiagrammen. Gemäß Fig. 1 ist der Sender der Uhr während 200 msec. tätig und etwa 5 sec. lang hört der Empfänger, ob irgend jemand Zweiter, Dritter usw. sendet. Wenn insofern nichts empfangen wird, beginnt der gleiche Zyklus nach 5 sec. Die Zustände gemäß Fig. 1 setzen sich dann regelmäßig fort, solange die Vorrichtung (Uhr, Taschengerät oder dgl.) eingeschaltet bleibt.The drawing shows a preferred embodiment of the invention in the form of time diagrams. Referring to FIG. 1, the transmitter of the watch during 200 msec. active and for about 5 seconds the receiver hears whether someone is sending second, third, etc. If nothing is received, the same cycle begins after 5 seconds. The states according to FIG. 1 then continue regularly as long as the device (watch, pocket device or the like) remains switched on.
Gemäß Fig. 2 wurde ein einziger Sender empfangen, was die Vorrichtung veranlaßt, den Start der Sendephase um T 1/2 zu verschieben. Diese Verschiebung findet statt unabhängig davon, ob eine Code-Übereinstimmung zwischen der eigenen Vorrichtung und der fremden Vorrichtung vorliegt.Referring to FIG. 2, a single transmitter has been received, which causes the device to move the start of the transmit phase to T 1/2. This shift takes place regardless of whether there is a code match between the own device and the external device.
