In elektromechanischen Systemen, wie beispielsweise einem Drehgeber, eingebaute elektronische Auswerte-Schaltungen benötigen meist eine einmalige, beispielsweise werkseitige, d.h. initiale Programmierung der Systemparameter. Diese Programmierung wird typischerweise in einem EEPROM abgelegt, damit sie nach jedem Wiedereinschalten zur Verfügung steht. Die für die Programmierung benötigten Programmierleitungen werden in der Regel nur für diesen Vorgang benutzt und sind danach obsolet und für den Anwender nicht zugänglich.Non-volatile, electronic memory modules of the EEPROM type, which can be erased and reprogrammed using a programming device, are widely used today.

Fig. 1 zeigt eine schematische Darstellung eines Systems aus Sender 100 und Empfänger 200, wobei der Empfänger 200 eine bevorzugte Ausführungsform eines Speicherbausteins, bildet. Das System ist zur drahtlosen Programmierung eines in den Speicherbaustein 200 integriertes EEPROM 230 ausgebildet .Fig. 1 shows a schematic representation of a system of transmitter 100 and receiver 200, wherein the receiver 200 forms a preferred embodiment of a memory module.

Die Funktionsweise der Programmierung wird im Folgenden beschrieben.The functionality of the programming is described below.
Das als Sender 100 ausgebildete Programmiergerät umfasst eine Einrichtung 110 zum Erzeugen eines modulierten Spannungssignals in Abhängigkeit von zu übertragenden digitalen Daten. Durch Anlegen des moduliertenThe programming device embodied as transmitter 100 comprises a device 110 for generating a modulated voltage signal as a function of digital data to be transmitted. By applying the modulated
Spannungssignals an eine als Magnetsender ausgebildete Spule 120 wird ein moduliertes Magnetfeld erzeugt. Die Modulationsspannung kann dem Sender 100 auch von einer separaten, nicht dargestellten Vorrichtung zugeführt werden. Das Magnetfeld wird vorteilhaft so moduliert, dass eine magnetische Störquelle keine versehentliche Programmierung auslösen kann.Voltage signal to a designed as a magnetic transmitter coil 120, a modulated magnetic field is generated. The modulation voltage can also be supplied to the transmitter 100 by a separate device, not shown. The magnetic field is advantageously modulated so that a magnetic source of interference can not trigger accidental programming.
Der Empfänger 200 umfasst eine Empfangseinheit 210 mit einem Hallsensor zum Messen der magnetischen Feldstärke des modulierten Magnetfelds. Hierzu wird beispielsweise zwischen den Anschlüssen A und C ein Stromfluß erzeugt und die durch den Halleffekt erzeugte Spannung zwischen den Anschlüssen B und D gemessen. Die Empfangseinheit 210 ist zur Programmierung direkt oder indirekt mit der als EEPROM ausgebildeten Speichereinheit 230 verbunden. Im dargestellten Ausführungsbeispiel ist zwischen die Empfangseinheit 210 und das EEPROM 230 der Decoder 220 geschaltet, welcher die empfangenen Signale entsprechend einem vorgegebenen Protokoll auswertet. Als Protokoll kommt vorzugsweise ein serielles Datenübertragungsprotokoll wie beispielsweise I2C oder SPI zum Einsatz. Je nach Einsatzzweck können die übertragenen Daten auch verschlüsselt werden. Im vorliegenden Ausführungsbeispiel ist ferner eine herkömmliche Programmierleitung 250 zur elektrischen Programmierung des EEPROMs 230 vorgesehen, mittels derer beispielsweise über eine integrierte Steuerlogik 240 eine Programmierung des EEPROMs 230 auf bekannte Art und Weise ermöglicht wird. Es wird durch die Erfindung im dargestellten Ausführungsbeispiel somit eine zusätzliche Programmierschnittstelle bereitgestellt, welche dem Anwender eine einfache und flexible Programmierung des EEPROMs 230 erlaubt. Da die erfindungsgemäße Programmierung drahtlos über ein Magnetfeld erfolgt, kann für spezielle Einsatzzwecke auf herkömmliche Programmierleitungen auch gänzlich verzichtet werden.The receiver 200 comprises a receiving unit 210 with a Hall sensor for measuring the magnetic field strength of the modulated magnetic field. For this purpose, for example, a current flow is generated between the terminals A and C and the voltage generated by the Hall effect between the terminals B and D measured. The receiving unit 210 is connected for programming directly or indirectly with the storage unit 230 designed as an EEPROM. In the illustrated embodiment, the decoder 220 is connected between the receiving unit 210 and the EEPROM 230, which evaluates the received signals according to a predetermined protocol. The protocol used is preferably a serial data transmission protocol such as, for example, I 2 C or SPI. Depending on the intended use, the transmitted data can also be encrypted. In the present embodiment, a conventional programming line 250 is further provided for electrical programming of the EEPROM 230, by means of which, for example, via an integrated control logic 240, a programming of the EEPROM 230 in a known manner is made possible. Thus, in the illustrated embodiment, the invention provides an additional programming interface that allows the user to easily and flexibly program the EEPROM 230. Since the programming according to the invention takes place wirelessly via a magnetic field, conventional programming lines can also be completely dispensed with for special purposes.
Ein besonderer Vorteil der Erfindung liegt darin, dass das verwendete Magnetfeld in der Lage ist, auch elektrisch geschirmte Systeme zu durchdringen. Der zum Signalempfang eingesetzte Hallsensor verursacht zudem nur geringe Mehrkosten und stellt somit eine geeignete Alternative zur drahtgebundenen Programmierung dar. A particular advantage of the invention is that the magnetic field used is able to penetrate even electrically shielded systems. In addition, the Hall sensor used for signal reception causes only small additional costs and thus represents a suitable alternative to wired programming.
