SENSOR MONITORING DEVICE AND METHOD, AS WELL AS SENSOR Russian patent published in 2013 - IPC G01D21/00 

FIELD: measurement equipment.

SUBSTANCE: group of inventions refers to sensor (12) monitoring device of a transport vehicle, and mainly of an automobile on fuel elements, to the sensor of the transport vehicle with the monitoring device, as well as to monitoring method of sensor (12) connected to the first data processing unit (16). The proposed monitoring device of sensor (12) of a transport vehicle, and mainly an automobile on fuel elements, which includes the following: the first monitoring module (18) intended to monitor operation of sensor (12) for failures, the second monitoring module (20) that is also designed for monitoring of operation of sensor (12) for failures, the third monitoring module (30) designed for monitoring of operation of the second monitoring module (20) of the sensor, the first data processing unit (16) including the first module (18) of the sensor monitoring and connected to sensor (12), the second data processing unit (24) connected to the first data processing unit (36) and having the possibility of outputting signal (26) of response to a failure at detection of malfunction of sensor (12). (dwg.1) Subject of the invention is also represented with a monitoring method of the sensor connected to the first data processing unit, which involves the following operations: monitoring of the sensor operation for failures with the first data processing unit; reserve monitoring of the sensor operation for failures; monitoring of performance of reserve monitoring operation for failures and output of signal of response to failure with the second data processing unit at detection of the sensor malfunction. Advantage of the invention consists in the fact that monitoring modules, and mainly the second and the third monitoring modules of the sensor, can be arranged in each control device connected through a signal bus to controlled sensors. The other advantage of the invention consists in the fact that requests for responses to a failure can be transmitted faster via discrete lines. Such a solution creates big advantages, mainly in electromobiles where a very quick reaction of a driver is required.

EFFECT: providing improved, more efficient and at the same time quick possibility of reliable output of signal of response to a failure at detection of a sensor malfunction; performance of distributed monitoring of components and functions in systems with sensors combined in a network; possibility of transfer of requests for reaction to a failure to other control devices via a non-signal bus, but via discrete lines.
