Abstract
A method for transmitting measured data from a sensor device to a control device is disclosed. The method is distinguished in that synchronization messages sent by the control device can be received in the sensor device and, on the basis of the reception of synchronization messages, the sensor device is put into a synchronous mode (SM) in which the sensor device sends data messages comprising the measured data to the control device in sync with the reception of the synchronization messages. A sensor device is also disclosed which is suitable for carrying out the foregoing method.
Claims20
A method for transmitting measured data from a sensor device to a control device, wherein synchronization messages sent by the control device are received in the sensor device and, on the basis of the reception of synchronization messages, the sensor device is put into a synchronous mode (SM) in which the sensor device sends data messages comprising the measured data to the control device in sync with the reception of the synchronization messages,
- wherein a check is performed to determine when synchronization messages sent by the control device are received in the sensor device, and the sensor device is put into the synchronous mode (SM) if the result of the check is that synchronization messages sent by the control device are received in line with a first time pattern, and wherein the sensor device is put into an asynchronous mode (AM) if the result of the check is that the synchronization messages are not received in the sensor device in line with the first time pattern, wherein in the asynchronous mode (AM) the sensor device sends data messages comprising the measured data to the control device at a prescribed frequency.
A sensor device comprising at least one sensor whose measured data are transmitted to a control device, wherein the sensor device is configured to receive synchronization messages sent by the control device, wherein, on the basis of the reception of synchronization messages, the sensor device is configured to be put into a synchronous mode (SM) in which the sensor device sends data messages comprising the measured data to the control device in sync with the reception of the synchronization messages,
- wherein the sensor device is configured to perform a check to determine when synchronization messages sent by the control device are received in the sensor device, and the sensor device is put into the synchronous mode (SM) if the result of the check is that synchronization messages sent by the control device are received in line with a first time pattern, and wherein the sensor device is put into an asynchronous mode (AM) if the result of the check is that the synchronization messages are not received in the sensor device in line with the first time pattern, wherein in the asynchronous mode (AM) the sensor device sends data messages comprising the measured data to the control device at a prescribed frequency.
A method for transmitting measured data from a sensor device to a control device comprising the steps of:
- transmitting synchronization messages via the control device;
- receiving the synchronization messages at the sensor device;
- operating the sensor device in a synchronous mode (SM), on the basis of the reception of synchronization messages, wherein in the synchronous mode (SM) the sensor device transmits data messages comprising the measured data to the control device in sync with the reception of the synchronization messages that are transmitted by the control device, and
- wherein a check is performed to determine when synchronization messages sent by the control device are received in the sensor device, and the sensor device is put into the synchronous mode (SM) if the result of the check is that synchronization messages sent by the control device are received in line with a first time pattern, and wherein the sensor device is put into an asynchronous mode (AM) if the result of the check is that the synchronization messages are not received in the sensor device in line with the first time pattern, wherein in the asynchronous mode (AM) the sensor device sends data messages comprising the measured data to the control device at a prescribed frequency.
