Abstract
According to the invention, data of several sensors (PIC1, PIC2) is transmitted to a control device (1) via a data bus (6), whereby a data relevance value is established in the sensor (PIC1, PIC2). Said data relevance value of the sensor (PIC1, PIC2) is stored on the bus (6) and only one single largest value of at least sensor (PIC1, PIC2) is transmitted to the control device (1).
Claims11
A method for transmitting data from a number of sensors (PIC 1, PIC 2) to a control device (1) via a data bus (6), with
- a) a data relevance value being determined in the sensor (PIC 1, PIC 2),
- b) the data relevance value of the sensor (PIC 1, PIC 2) being applied to the bus (6), and
- c) only the greatest data relevance value from the sensors (PIC 1, PIC 2) being transmitted to the control device (1).
A circuit arrangement for carrying out the method as claimed in one of the preceding claims, having a number of sensors (PIC 1, PIC 2), having a data bus (6) and having a control device (1) , characterized in that the sensors are connected via the data bus (6) to the control device (1) using the wired-AND principle, so that only one data item from one sensor (PIC 1, PIC 2) is passed through.
