<p>PURPOSE:To provide a sensor-checking system in a mobile farming machine such as a combine harvester, enabling sensor abnormalities to be detected easily and assuredly. CONSTITUTION:This sensor-checking system has a sensor for automatic control giving outputs according to displacement, a switching means to be operated when the detection status of the sensor is checked, a memory for sensor detection output, and a comparison means to compare the state changes in sensor detection output by using data in the memory. In this case, both the sensor and switching means are set up on the input side. Besides, this system has a control section to give driving output when the change in sensor detection output is determined in the state that the switching means is being in operation and an informing means formed on the output side of the control section and actuating by driving output.</p> |
