Abstract

PURPOSE:To prevent erroneous operation and reliably avoid a mistake in setting a model by providing a controller which checks the combination of each setting operation of a power source setting means for setting a single phase/three phases and a voltage setting means for setting 100V/200V and detects the presence of a mistake in setting a model of a grain drying machine. CONSTITUTION:Respective setting means 33, 35, 37 for moisture, the kind of grain and the loaded quantity thereof in an operation unit 14 are manipulated while being brought into agreement with the displays of respective display lamps 34, 36, 38, and respective setting means 41', 42' for a power source and a voltage are manipulated while being brought into agreement with a model. When a starting time key 31b is manipulated to start drying work after setting each item in such ways as menetioned above, each signal set by a model setting means, the power source setting means 41' for setting a single phase/three phases and the voltage setting means 42' for setting 100V/200V is read, and whether these combinations are correct is determined. In the case where the combinations are not good, it is displayed on a display unit 43, and, in the case of the correct combinations, hot air is blown to start the drying of grain when all the combinations in a drying machine 1 become correct.

And so on.

The type determination is performed as shown in FIG. 1. In the type determination abnormality processing, when the type determination is unknown, only the inspection mode for detecting an abnormality can be shifted and other operations and operations cannot be performed. I am trying. This type determination abnormality is a type determination jumper wire combination abnormality, and, for example, a connector contact failure of the paddy flow sensor 46 may be considered, and the display on the display unit 43 is displayed by, for example, an abnormality display 25E0 and a number and a symbol. In addition, when the setting means 41 ', 42' for setting the type determination has a setting error, the abnormality display is indicated by 25E1, a numeral and a symbol. (It has a structure as shown in the type determination abnormality table of FIG. 8.) The power supply setting means 41 'is a single phase depending on the operation position.
Alternatively, the configuration is such that three phases are input to the control device 45 only once when the power is turned on, and the setting of this switch of the slide switch system is such that single phase is short-circuited and three phases are open.

The voltage setting means 42 'is 100 V depending on the operating position of the slide switch type switch.
In this configuration, either 200 V or 200 V is input to the control device 45 only once when the power is turned on. The setting is 100 V short-circuited and 200 V open. Hereinafter, the operation of the above embodiment will be described.

Each setting means 33, 35, 3 of the operating device 14
7 is operated according to the predetermined display position of each display lamp 34, 36, 38, and each setting means 41 ', 42' is operated according to the model, various items are set, and the drying operation is started. By operating the starting means 31b, the dryer 1 is started and started (step 101), the model setting means is read, the operation of the setting means 41 'for single-phase / three-phase setting is read, and 100V / 200V. Setting means 4 for setting
The operation 2'is read (step 102), a combination OK is detected (step 103), and if it is detected as NG, a combination abnormality is displayed on the display unit 43 (step 10).
4) and then returned (step 105). Step 1
When it is detected as OK in 03, the process proceeds to step 105. When all the combinations of the dryer 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 passes through the grain drying chambers 8 and 8 from the blower chamber 10 to After passing through the exhaust chambers 9 and 9 and the exhaust passage chamber 16, the exhaust device 15 sucks and exhausts the air.

The grains stored in the grain storage chamber 7 are dried by being exposed to dry hot air while flowing down from the storage chamber 7 into the drying chambers 8, 8. It is fed out and flows down, and from the grain collecting gutter 12 through the supply gutter 28, the grain raising machine 2
5 is transferred and supplied by the lower transfer spiral to the inside of the container 5, is conveyed to the upper part by the bucket conveyor 26, and is transferred and supplied by the upper transfer spiral from the ejection cylinder 27 to the diffusion plate 24 through the transfer gutter 5 by the diffusion plate 24. It is uniformly diffused and reduced into the storage chamber 7 and circulated and dried.

When the moisture sensor 2 detects the grain moisture which is equal to or less than the finishing target moisture set by the operation of the moisture setting means 33, it is determined that the drying is completed, and the controller 45 automatically controls the dryer to dry it. 1 is automatically stopped, and the drying of the grain is stopped. FIG. 9 is a diagram showing another action, showing action control of communication processing. Drying work is turned on by communication
-OFF, information is passed, and various items are displayed on the display unit 43. Control output is turned ON-OFF.
At the time, even if it is the communication timing, the control for delaying the timing for the predetermined time is performed as follows. Drying is started (step 201), it is detected whether it is the communication timing (step 202), and if YES is detected, it is detected whether the control output is ON → OFF or OFF → ON (step 203), and YES. If it is detected that the 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 is returned (step 207). .

NO in step 202 and step 205
If it is detected, the process proceeds to step 207 and returns.
When NO is detected in step 203, step 205
The process proceeds to step 206 and returns after step 206. Due to the above, noise is always generated when the control output is turned on and off, but if this noise is transmitted to the communication, it may malfunction due to garbled communication data. Further, it takes man-hours and cost to suppress this noise by the circuit, but by shifting the communication timing, it is possible to suppress the increase in communication accuracy, malfunction due to noise, and cost increase due to circuit noise handling.

FIG. 10 is a view showing another operation, showing the operation control of the communication processing. By communication, the drying work is turned on and off, information is passed, and the display unit 43
It is configured to display various items to, the communication data number is provided in the communication data, and from the communication baud rate and the communication data number,
The communication end time is calculated, and if the communication is not ended within that time, it is determined that the communication is abnormal, and the control for performing the retry (retransmission) process is performed as follows. Control on the communication side during drying (step 301), it is detected whether it is receiving (step 302), if YES is detected, it is detected whether the number of communication data has been acquired (step 303), and if YES is detected, communication is performed. The end time is calculated (step 304), it is detected whether reception is completed (step 305), and if NO is detected, the communication end time UP is detected (step 306), and YE
If S is detected, a retry (retransmission) process is performed due to communication abnormality (step 307), and the process is returned (step 30).
8).

NO is detected in steps 302, 303 and 306, and YE is detected in step 305.
When S is detected, the process proceeds to step 308 and returns. As described above, when the communication data is interrupted or shifted due to noise or the like, the communication abnormality can be promptly determined by the communication end time. In addition, since the number of communication data is unstable for each communication, the judgment of communication abnormality is delayed at a fixed communication end time, work is stopped, judgment by information,
Display screen processing and the like may be delayed, but by eliminating these problems, the accuracy of handling a communication error can be improved.
