By operating the starting means 31b, the dryer 1 is started and started (step 101), reading of the type setting means, reading of the operation of the setting means 41 'for single-phase / three-phase setting, and 100V / 200V. The setting means 4 for setting
The operation 2 'is read (step 102), a combination OK is detected (step 103), and if an NG is detected, a combination error is displayed on the display unit 43 (step 10).
4), and the process returns (step 105). That is,
It is determined as a combination other than OK in FIG. 2, for example,
(A) kW motor specification is three-phase 100V, (B) kw
The motor specifications are for single-phase 100V and three-phase 100V. If OK is detected in step 103, the process proceeds to step 105. When all of the combinations of the dryers 1 are OK, hot air is generated from the burner 3, and the dry hot air in which the hot air and the outside air are mixed is sent from the blowing chamber 10 to each of the grain drying chambers 8,
8, the air is sucked and exhausted by the exhaust fan 15 through the exhaust chambers 9, 9 and the exhaust path chamber 16. The grains stored in the grain storage chamber 7 are dried by being exposed to hot dry air while flowing down from the storage chamber 7 through the drying chambers 8, 8. It is fed out and flows down, and the grain raising machine 2
5 is transported and supplied by a lower transport spiral, is transported upward by a bucket conveyor 26, is transported and supplied by an upper transport spiral from a discharge tube 27 through a transport gutter 5 onto a diffusion board 24, and is transported by the upper transport spiral. It is evenly diffused and reduced into the storage chamber 7 and circulated and dried. When the moisture sensor 2 detects the same or less than the target moisture content set by the operation of the moisture setting means 33, it is determined that the drying has been completed, and the control unit 45 automatically controls the drying device. 1 is automatically stopped, and drying of the grain is stopped. FIG. 9 is a diagram showing another operation, and shows the operation control of the communication processing. Drying work ON by communication
-OFF, transfer information, and display various items on the display unit 43.
At this time, even if it is a communication timing, the control for delaying the predetermined time timing is performed as follows. Drying is started (step 201), it is detected whether it is communication timing (step 202), and if YES is detected, the control output is detected as ON → OFF or OFF → ON (step 203), and YES Is detected, a communication start timer is set (step 204), the communication start time UP is detected (step 205), and if YES is detected, communication processing is performed (step 206), and the process returns (step 207). . NO at steps 202 and 205
Is detected, the process proceeds to step 207 and returns.
If NO is detected in step 203, step 205
The process proceeds to step 206 and is returned. As described above, when the control output is turned on and off, noise always occurs. However, if this noise occurs in communication, communication data may be garbled or malfunction. In order to suppress this noise with a circuit, man-hours and cost are required. However, by shifting the communication timing, it is possible to improve communication accuracy, malfunction due to noise, and suppress cost increase due to noise in the circuit. FIG. 10 is a diagram showing another operation and shows the operation control of the communication processing. By communication, the drying operation is turned ON / OFF, information is transferred, and the display unit 43
It is a configuration to display various items in the communication data, the communication data number is provided in the communication data, and the communication baud rate and the communication data number
The communication end time is calculated, and if the communication does not end within the time, it is determined that the communication is abnormal, and control for performing a retry (retransmission) process is performed as follows. The control on the communication side during drying (step 301) detects whether reception is being performed (step 302), and if YES is detected, it is detected whether the number of communication data has been acquired (step 303). If YES, communication is performed. The end time is calculated (step 304), and it is detected whether the reception is completed (step 305). If NO is detected, the communication end time UP is detected (step 306), and YE is detected.
If S is detected, a retry (retransmission) process is performed due to a communication error (step 307), and the process returns (step 30).
8). NO is detected in steps 302, 303 and 306, and YE is detected in step 305.
If S is detected, the process proceeds to step 308 and returns. As described above, when communication data is interrupted or shifted due to noise or the like, a communication abnormality can be quickly determined based on the communication end time. In addition, since the number of communication data is unstable for each communication, at a constant communication end time, the determination of the communication abnormality is delayed, and the work stoppage, the information determination,
Display screen processing and the like may be delayed, but by eliminating these, the accuracy of response to a communication error can be improved.
