3rd moisture meter transducer, the Rice Kernel Moisture Content that the 3rd moisture meter transducer will be detected compares with preset value, if being equal to or small
In preset value, then Rice Kernel Moisture Content numerical value is sent to display screen and enters next step, if being more than preset value, paddy contained
Water rate score is sent to display screen and continues to detect Rice Kernel Moisture Content；
S3：The Rice Kernel Moisture Content that 3rd moisture meter transducer will be detected compares respectively with the Rice Kernel Moisture Content for sending
Compared with, if the 3rd moisture meter transducer detection Rice Kernel Moisture Content it is identical with the Rice Kernel Moisture Content that the second moisture meter transducer is detected or
Approximately the same, then the 3rd moisture meter transducer sends alarm signal to warning device, if the rice of the 3rd moisture meter transducer detection
Paddy moisture content is different from the Rice Kernel Moisture Content that the second moisture meter transducer is detected, then return to step S2.
Present invention tool has the advantage that：
The system that the present invention is provided sets three moisture meter transducers, and three moisture meter transducers are located at tempering room respectively
At different height on the wall of side, because the paddy for detecting is by tempering or at least part of tempering, the 3rd moisture meter transducer
Detection is complete tempering, and it is identical with the numerical value that the second moisture meter transducer is detected or approximately the same, turns out paddy and obtains
When having arrived complete tempering, and the numerical value of the 3rd moisture meter transducer detection simultaneously equal to or less than preset value, paddy is turned out
Overall moisture content has reached the target of requirement, and testing result of the invention is closer to real moisture content, the rice of detection
Paddy moisture content is more accurate.
