Embodiment Construction

[0030] exist figure 1 A device with a signal generator 10 and a signal receiver 20 can be seen in FIG.

[0031] The signal generator 10 has a time reference 11 and a control device 12 which can be, for example, a programmable computing device. The signal receiver 20 has a time reference 21 and a control device 22 . The control device 22 can also be, for example, a programmable computing device.

[0032] If the control device 12 of the signal generator 10 determines that an event has occurred which should be reported to the signal receiver 20, the signal generator generates a corresponding event signal E(Ta, Taz). The event signal E(Ta, Taz) describes the event that occurred and specifies the event time, ie the event time Ta as the time reference 11 according to the signal generator 10 . Furthermore, the event signal E(Ta, Taz) gives the event time point Taz according to the time reference 21 of the signal receiver 20 . Because the control device 12 of the signal generator ...

Abstract

The invention relates inter alia to a method for transmitting an event signal (E (Ta, Taz)) from a signal transmitter (10) to a signal receiver (20), wherein the event signal characterises an event and the time of the event. According to the invention, the signal transmitter produces an event signal which characterises the time (Ta) of the event according to the time base (11) of the signal transmitter and a correction value (Taz) which indicates, indirectly or directly, the time lag, estimated by the signal transmitter, between the time base (21) of the signal receiver and the time base of the signal transmitter. After receiving the event signal, the signal receiver estimates the time of the event according to the time base of the signal transmitter, taking into account the time of the event estimated by the signal transmitter according to the time base of the signal receiver and a time lag estimated by the signal receiver between the time base of the signal receiver and the time base of the signal transmitter. When evaluating the event signal, the signal receiver takes into account the time of the event indicated in the event signal according to the time base of the signal transmitter and the time of the event estimated by the signal receiver after receiving the event signal according to the time base of the signal transmitter.

Description

technical field [0001] The invention relates in particular to a method for transmitting an event signal from a signal generator to a signal receiver, wherein the event signal characterizes an event or an event occurrence and an event time point. Background technique [0002] If, in addition to events like this one, the time of event occurrence is to be safely handled by the signal receiver, it must be ensured that the signal receiver takes into account the correct point in time of the event. This becomes difficult when the signal generator and the signal receiver are operated with independent time bases, which may have offsets and time offsets. Contents of the invention [0003] The technical problem underlying the invention is therefore to provide a method for transmitting an event signal from a signal generator to a signal receiver, in which path differences and time offsets between time references can be taken into account. [0004] This technical problem is solved acc...
