Description
Der Erfinder geht aus von einer Vorrichtung nach der Gattung des Hauptanspruches.The inventor starts from a device according to the class of the main claim.
Es sind bereits zahlreiche Vorrichtungen zur drahtlosen Messung von Entfernungen bekannt, die auf optischen, akustischen oder hochfrequenten Effekten beruhen.Numerous devices for wireless distance measurement are already known, based on optical, acoustic or high-frequency effects.
Befindet sich in der zu messenden Entfernung ein reflexionsfähiges Objekt, ist es bekannt, ein impulsform!ges Signal auszusenden und aus der Laufzeit zwischen dem ausgesannten Signal und dem empfangenen reflektiertem Signal die Entfernung zwischen der Meßvorrichtung und dem Objekt zu bestimmen. Üblicher weise werden hierzu Mirkowellensignale , Ultraschallsignale oder Infrarotsignale verwendet.If there is a reflective object at the distance to be measured, it is known to send out a pulse-shaped signal and to determine the distance between the measuring device and the object from the transit time between the transmitted signal and the received reflected signal. Microwave signals, ultrasonic signals or infrared signals are usually used for this purpose.
Nachteil der Erfindungen ist es jedoch, das es nicht möglich ist mit geringen technischem Aufwand eine störsichere räumliche Bestimmung des Objektes herbeizuführen.The disadvantage of the inventions, however, is that it is not possible to achieve an interference-free spatial determination of the object with little technical effort.
Die erfindungsgemäße Vorrichtung mit dem kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber dem Vorteil, durch geringen Kostenaufwand die Kombination von Reflexionsmodulen zu ermöglichen, ausgehend von nur einem Meßsignal und somit das Wirkungsfeld beliebig zu erweitern.The device according to the invention with the characterizing features of the main claim has the advantage of enabling the combination of reflection modules at low cost, starting from only one measurement signal and thus expanding the field of action as desired.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen der im Hauptanspruch angegebenen Vorrichtungen möglich zur räumlichen Differenzmessung und Voluminabestimmung durch Erhöhung der Reflexionsmittel.The measures listed in the subclaims enable advantageous further developments of the devices specified in the main claim for spatial difference measurement and volume determination by increasing the reflection means.

Die Figuren zeigen die Blockschaltbilder der Vorrichtungen zur Messung von Entfernungen und kombiniert zum Messen von räumlichen Entfernugen und Volumina, die Ultraschall und Infrarot oder Ultrakurzwellensignale verwenden.The block diagram of the different embodiments of the device according to the invention is shown in the drawings and explained in more detail in the following description. The figures show the block diagrams of the devices for measuring distances and combined for measuring spatial distances and volumes, which use ultrasound and infrared or ultra-short wave signals.
Die erfindungsgemäße Vorrichtung zur Messung von Entfernungen von einem ersten Punkt zu mehreren anderen Punkten, besteht aus einer frei beweglichen Meßeinheit ( A(I) ) und an mehreren frei beliebig wählbaren unterschiedlichen Punkten fest angebrachten Reflexionsmitteln ( A(2)..A(n)).The device according to the invention for measuring distances from a first point to several other points consists of a freely movable measuring unit (A(I)) and reflection means (A(2)..A(n)) fixedly attached to several freely selectable different points.
- einer Logikschaltung mit Zeitmessern und Anzeigeeinheit(LA).- a logic circuit with timers and display unit (LA).
- einem Ultrschallsender(US) welcher von einer Logik (LA) gesteuert wird.- an ultrasound transmitter (US) which is controlled by a logic (LA).
- einer Empfangseinheit(EU) welche von den Reflexionsmitteln (A(2)..A(n))empfängt und die Signale an die Zeitemesser in der Logiksteuerung (LA) weitergibt.- a receiving unit (EU) which receives from the reflection means (A(2)..A(n)) and forwards the signals to the timers in the logic control (LA).
- einen Raumtemperaturmesser (T) welcher mit der Logik (LA) verbunden ist.- a room temperature sensor (T) which is connected to the logic (LA).
- ein Ultrakurzwelle oder Infrarot Sender/Emfänger (C) zur Datenübertragung an andere externe DV Gräte (F) oder Reflexionsmitteln (A(2) . .A(n)) .- an ultra-short wave or infrared transmitter/receiver (C) for data transmission to other external DV devices (F) or reflection devices (A(2) . .A(n)).
Die Reflexionsmittel *(Ä(2*) . The reflection means *(Ä(2*) . .K(K)) .K(K)) bestehen ausconsist of
- einer Logikschaltung (L) mit Frequenzwandler.- a logic circuit (L) with frequency converter.
- einen Ultraschallempfänger (UE) der über die Logik (L) mit dem Reflexionssender (RS) in Wirkverbindung steht.- an ultrasonic receiver (UE) which is in operative connection with the reflection transmitter (RS) via the logic (L).
- eine Infrarot oder Ultrakurzwellen Sende/Empfangseinheit (C) zur Kommunikation mit andern Modulen (A(I)..A(n) oder (F).- an infrared or ultra-short wave transmitter/receiver unit (C) for communication with other modules (A(I)..A(n) or (F).
Nach in Betriebnahme des Moduls A(I) sendet und empfängt die Logik (LA) über (C) Konfiguationsdaten von den Logiken (L) in den Modulen A(2)..A(n).Jedes Modul (A(2)..A(n)) erhält für den Betrieb eine nur einmal vorkommende Identifikationsnummer I welche die Sendefreqenz von (RS) in A(n) oder die Telegrammkennung von (L) in a(n) bestimmt.After commissioning the module A(I), the logic (LA) sends and receives configuration data via (C) from the logic (L) in the modules A(2)..A(n). Each module (A(2)..A(n)) receives a unique identification number I for operation, which determines the transmission frequency of (RS) in A(n) or the telegram identifier of (L) in a(n).
Nun erzeugt die Logikeinheit (LA) Steuerimpulse, die den Ultraschallsender(US) pulsen. Dadurch gelangen impulsförmige Ultraschallsignale zu den Ultraschallempfängern (UE) in den Reflexionsmitteln (A(2)..A(n)). Die Logik(L) in (A(n)) erzeugt aus diesen Signalen Impulse für den Reflexionssender (RS) in (A(n)). Die Empfangseinheit(EU) in (A(I)) empfängt von Reflexionsmittel (A(2)..(A(n)) die unterschiedlichen Frequenzimpulse oder Telegramme welche unterschiedliche Zeitmesser in (LA) stoppen. In (LA) wird die Gültigkeit der Impulse überprüft und aus der Meßzeit unter Berücksichtigung der Raumtemperatur die Differenzstrecke berechnet. Die Räumlichen Koordinaten oder Volumina (aus Berechung der Raumdifferenzen) werden über (LA) Anzeigt oder über (C) in (A(I) an andere externe DV Geräte (F) übertragen und wenn erwünscht weiterverabeitet.- 7 -The logic unit (LA) now generates control pulses that pulse the ultrasonic transmitter (US). This means that pulse-shaped ultrasonic signals reach the ultrasound receivers (UE) in the reflection means (A(2)..A(n)). The logic (L) in (A(n)) generates pulses from these signals for the reflection transmitter (RS) in (A(n)). The receiving unit (EU) in (A(I)) receives the different frequency pulses or telegrams from the reflection means (A(2)..(A(n)) which stop different timers in (LA). In (LA) the validity of the pulses is checked and the difference distance is calculated from the measurement time taking the room temperature into account. The spatial coordinates or volumes (from calculation of the room differences) are displayed via (LA) or transferred via (C) in (A(I) to other external DV devices (F) and processed further if required.- 7 -
