Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an abnormality processing control method for agricultural machinery, etc., and a system for displaying the details of an abnormality during control.

It displays whether or not subsequent operation is possible and allows efficient work.
It can also be used for combine harvester work machines, etc.

(Prior Art and Problems to be Solved by the Invention) In a rice huller, if an abnormality occurs during hulling control, the abnormal location is displayed. When this abnormality is restored to a normal state, the abnormality display is canceled. However, with this type of abnormality display, it is difficult to judge what kind of abnormality it is and what kind of response should be taken. 1. It may unnecessarily reduce work efficiency.

The present invention is intended to eliminate such defects, and to perform efficient control work by determining and displaying whether subsequent operation is possible or not, depending on the nature of the abnormality.

(Means for Solving the Problems) This invention displays the content of the abnormality as a message and outputs the buzzer 4 based on the occurrence of an abnormality while reading the inputs of sensors 1 to 3, so that the operation can be continued in other control modes. Turn off the buzzer stop switch 6 to determine whether the main motor 5 is in a running state or a standby state in which the main motor 5 must be stopped.
This is an abnormality processing control system for agricultural machinery, etc., characterized in that a message is displayed by the following.

(Operation and Effects of the Invention) When an abnormality occurs in any part during the control work of agricultural machinery and equipment, a message is displayed indicating the abnormality by reading the input from sensors 1 to 3 related to the abnormality. , the notification is made by the buzzer 4 output. The currently occurring abnormality is switched to an operating state in which operation can be continued in another control mode, or a standby state in which operation is not possible in which the main motor 5 must be stopped, and the operator can stop the buzzer. By operating the switch 6, a message is displayed indicating whether the device is in the operating state or in the standby state.

In this way, by turning off the buzzer 4 by operating the buzzer stop switch 6 that notifies you of an abnormality, the abnormality is displayed as a message whether in the operating state or in the standby state, so that in the operating state, the operation can be continued in other operation control modes. is,
In the standby state, the main motor 5 is stopped, and the operator can continue the operation efficiently and safely while checking whether the operation is proper or not and the primary operation instructions by looking at the message display.

(Example) To explain a rotating huller, it consists of a huller 7 having a pair of dehulling rolls and a sorting device 8 having a rotary sorting tube. The paddy supplied by the opening of the shutter 10 is dehulled while flowing down into the gap between the rolls between a pair of devolatilizing rolls, and is wind-sorted as polished rice by a wind sorting device below. The department is
The structure is such that the de-densation rate sensor 3, which detects the de-pastry rate by sampling, is bypassed. Further, the sorting device 8 includes a sorting tube that receives the scraped rice and sorts it into brown rice and paddy while rotating, and a brown rice grain lifting machine 11 that takes out the brown rice sorted by the sorting tube out of the machine.
etc., and the polished rice is fried by a grain frying machine 12 and fed into the sorting cylinder.

Husking device! The 7th side fuselage has a microcomputer CP.
A controller 13 is provided, and a box of the controller 13 is provided with a character display section 14 for displaying messages such as current values, voltage values, rotation speed, etc. in characters based on the output from the microcomputer CPU. An abnormality monitor LED display section 15 is provided to display the abnormality on a diagram, and an operation switch 16 for starting and stopping the operation of the huller, a stop switch 6 for the buzzer 4 that emits an abnormality alarm, and a rotation speed of the sorting cylinder are installed. A rotation adjustment switch 17, etc., which can be adjusted by pressing it high or low, is provided.

In Fig. 1, there are various types of sensors 1 and 2, such as a paddy sensor that detects the presence or absence of the amount of paddy in the paddy funnel 9, a shutter sensor that detects the opening and closing of the shutter 1o, and a shutter sensor that detects the gap between the rolls. A roll gap sensor to detect the rotation speed of the devolatilizing roll, a roll rotation sensor to detect the rotation speed of the devolatilizing roll, a paddy flow sensor to detect whether or not paddy is flowing down, a sorting tube rotation sensor to detect the rotation speed of the sorting tube, and the sorting status of brown rice. A control configuration is provided in which a brown rice sensor detects the amount of unhulled rice, a layer thickness sensor detects the layer thickness of a certain amount of peeling in the sorting cylinder, etc., and controls the predetermined hulling sorting.

In addition, the deburring rate sensor 3 transmits a sample of rice grain by grain within the sensor light emitting area that emits light to the light receiving element based on a predetermined light amount voltage from the light emitting element, and detects the transmission of this sensor light. The demolition rate is calculated based on the transmittance of the amount of light, and the roll opening/closing control motor 18 adjusts the roll gap while comparing the detected demolition rate with a preset demolition rate.
By controlling the output, the process is controlled in accordance with the set demolition rate.

Further, the sorting cylinder is controlled by the output of the sorting control motor 19 so that the number of revolutions per rotation is maintained in a state suitable for sorting.

When the rice hulling operation starts, the reading of the input from each of the five sensors 1 to 3 is started, and if an abnormality occurs, the content of the abnormality is displayed on the character display section 14, and the abnormal location is lit on the LED display section 15. be done. At the same time, the buzzer 4 is output.

It is determined whether this abnormality allows operation to continue in another control mode or cannot continue operation, and if the abnormality is such that operation cannot be continued, the main motor is stopped and the rice hulling operation is continued. However, if it is possible to continue operation in another control mode, switch the control mode and continue operation. For example, in the devolatilization rate control using the devolatilization rate sensor 3, if an abnormality occurs in the devolatilization rate sensor 3, culling control using load control is automatically performed until the abnormality is cleared. It is like controlling the switching to . At this time, when the abnormality of the devolatilization rate sensor 3 is cleared, load control is automatically returned to devolatilization rate control.

In this way, when the buzzer 4 is output and it is determined whether the operation is possible or not, when the worker presses the buzzer stop switch 6 to turn on the buzzer 4, the warning sound of the buzzer 4 disappears. At the same time, a message indicating the operating status is displayed on the one-character display section 14.

Alternatively, a message in a standby state is displayed. For this reason,
The message indicating the operating state indicates which control mode has been entered, and the message indicating the standby state indicates the next operation instruction, which the operator confirms based on the display.
