Moreover, the disadvantage is that, as a result of this direct reference, the provision of the sensor value is not decoupled from the sensor dead time and therefore no additional position value is provided

Embodiment Construction

[0069] exist Figure 1a start in Figure 1a -d shows the basic process of synchronous signal generation according to the synchronous method of the present invention. The primary sensor moves forward from the start time at time V 1 at and at a later time V 2 Measure the sensor value V at . Measured value V 1 until the observation time t 3 are available, and the measured value V 2 at time t 3 becomes available everywhere. from V 2 The elapsed time of collection until it is available corresponds to the latency L of the master sensor.

[0070] like Figure 1b As depicted in , the stored parameter values ​​of the extrapolation rules are now calculated and derived from the two available time / measurement pairs (t 1 |V 1 ) and (t 2 |V 2 )supply. In this example, the usage consists of a linear algorithm. If another algorithm, eg based on higher order polynomials, is more convenient, even more time / measurement value pairs are collected and used for parameter value calcul...

Abstract

The method involves providing extrapolation rule and extrapolated time associated with intended value of a master sensor to be predetermined on basis of the extrapolation rule. A first synchronization signal is transmitted to a slave sensor when the extrapolated time occurs and delay time different from the extrapolated time in a temporally defined manner occurs. Recording of slave sensor value is triggered by a first synchronization signal. The intended value and the slave sensor value are provided as connected value tuple. An independent claim is also included for a sensor measuring system.

Description

technical field [0001] The invention relates to a sensor synchronization method according to the preamble of claim 1 and to a sensor measuring system according to the preamble of claim 13 . Background technique [0002] In measurement systems that include multiple sensors, it is often desirable to collect sensor values ​​from all sensors simultaneously in order to generate a connection data record. For example, if the location of a point object is to be fully determined at a particular time, three corresponding coordinates must be collected simultaneously. [0003] One option for this purpose is to simultaneously transmit a trigger signal to all sensors involved which triggers the collection of measured values ​​of the respective sensor. However, a problem therein is that, in general, not all measurements are collected at a single time due to different types of time delays. For example, delays occur due to different signal runtimes of the trigger signal and measurement sig...
