[Example 1]
Next, operation | movement of the agricultural machine control system 10 which concerns on Example 1 of the agricultural machine 30 of this invention is demonstrated using FIG. FIG. 2 is a flowchart according to the first embodiment of the control system shown in FIG.
First, in step S1, a time (theft alarm setting time) when the farm work machine 30 is not used is set. That is, the agricultural machine 30 such as a combine or a rice transplanter does not work early in the morning or at night, and the tractor may work from evening to night, but does not work at midnight. Therefore, a time during which no work is performed is set for each agricultural machine. However, since combine and rice transplanter work is limited, it is possible to set the date. This time setting is input by the input unit 22 of the portable terminal 20 or the input means 40 of the farm work machine 30.
Next, in step S2, it is determined whether the anti-theft system is turned on. ON (operation) and OFF (release) of the anti-theft system are set in advance by the user operating the input unit 22 of the mobile terminal 20 or the input means 40 of the agricultural machine 30. This anti-theft system is released when inspection or maintenance is performed at the end of work or storage, or when it is moved, etc., and is activated at other times. If this determination is “NO” (if the theft system is not turned on), the process returns to step S2. If the determination is “YES” (if the theft system is ON), the process proceeds to step S3.
In step S3, it is determined whether the engine is started and engine start information is detected by the engine output unit 48. If this determination is “NO” (if engine start information is not detected), the process returns to step S3 again. If the determination is “YES” (if engine start information is detected), the process proceeds to step S4.
In step S4, the current time is transmitted to the set time control means 34.
Next, in step S5, it is determined whether or not the current time is within the theft alarm setting time detected in step S5. If the determination is “YES” (if the current time is within the burglar alarm setting time detected in step S5), the engine start is treated as non-regular, that is, the possibility of theft. Proceed to S6. If the determination is “NO” (if the current time is not within the burglar alarm setting time detected in step S5), the engine start is treated as normal and the series of processes ends.
That is, when the engine is started in a state where the anti-theft system is operating, the engine start state detecting means 46 arranged in the engine output section 48 is turned on and the signal is transmitted to the agricultural machine control means 31 and the current time Is transmitted to the set time control means 34. In the set time control means 34, when the current time is not within the theft alarm set time, it is a work time zone, so it is possible to travel and work without issuing an alarm.

Next, in step S6, an alarm is issued. That is, the buzzer or horn is sounded and the alarm lamp blinks. However, the alarm means is not limited, and an alarm can be given by voice. If the engine is started for maintenance without accidentally releasing the anti-theft system and an alarm is issued, the anti-theft system is released using the input means 40 or the portable terminal 20. When canceling with this input means 40, a password can be set, another key can be used, or it can be canceled in conjunction with other operations so that it cannot be easily canceled.
In step S7, simultaneously with the operation of this alarm, the position information detecting means (GPS) 38 is operated to detect the position information where the agricultural machine 30 is currently located.
Next, in step S <b> 8, this position information is transmitted to the portable terminal 20 by the communication means 32 of the farm work machine 30. In addition, it becomes possible to track even if it is moving by operating this antitheft system every predetermined time until it is released. Moreover, a long time alarm can be actuated by issuing a warning for a predetermined time every predetermined time.
On the other hand, the mobile terminal 20 to which the position information is transmitted causes the display unit 23 to display the position information on the map and stores the position information in the storage unit 24. Here, the user confirms the position information displayed on the display unit 23 to notify the police that the user is stolen other than the position where the farm equipment 30 is stored, and based on the position information. Can be tracked and easily retrieved.

  As described above, in the agricultural machine 30 including the communication unit 32 that communicates with the portable terminal 20, the position information detection unit (GPS) 38 that detects the position information of the machine body, and the engine start state detection unit that detects the start state of the engine 46 and a setting time control means 34 for setting a theft alarm setting time on the portable terminal 20 or the farm work machine 30 and determining whether or not it is within the theft alarm setting time when the engine is started, When it is determined by the set time control means 34 that it is within the theft alarm set time, the position information detected at that time is transmitted to the portable terminal 20 and an alarm is notified.

  Thereby, when the engine of the farm work machine 30 is started within the set alarm time, and the farm work machine 30 is likely to be stolen, the occurrence can be detected even in a remote place. Therefore, it is possible to immediately track it and prevent the farm machine 30 from being stolen.

[Example 2]
Next, operation | movement of the agricultural machine control system 10 which concerns on Example 2 of the agricultural machine 30 of this invention is demonstrated using FIG. FIG. 3 is a flowchart according to the second embodiment of the antitheft control system shown in FIG.

Next, in step S2, it is determined whether the anti-theft system is turned on. If this determination is “NO” (if the theft system is not turned on), the process returns to step S2. If the determination is “YES” (if the theft system is ON), the process proceeds to step S3.
In step S3, it is determined whether or not door opening / closing information is detected by the door opening / closing state detecting means 42. If this determination is “NO” (if door opening / closing information is not detected), the process returns to step S3 again. If the determination is “YES” (if door opening / closing information is detected), the process proceeds to step S4.
In step S4, the current time is transmitted to the set time control means 34.
Next, in step S5, it is determined whether or not the current time is within the theft alarm setting time detected in step S5. If the determination is “YES” (if the current time is within the theft alarm set time detected in step S5), the door opening / closing is treated as an unauthorized one, that is, the possibility of theft. Proceed to S6. If the determination is “NO” (if the current time is not within the burglar alarm setting time detected in step S5), the opening and closing of the door is treated as normal, and the series of processing ends.
That is, when the door is opened and closed while the anti-theft system is in operation, the door open / closed state detecting means 42 arranged on the door 44 is turned ON and the signal is transmitted to the agricultural machine control means 31 to set the current time. It is transmitted to the time control means 34. In the set time control means 34, when the current time is not within the theft alarm set time, it is a work time zone, so it is possible to travel and work without issuing an alarm.

Next, in step S6, an alarm is issued. That is, the buzzer or horn is sounded and the alarm lamp blinks.
In step S7, simultaneously with the operation of this alarm, the position information detecting means (GPS) 38 is operated to detect the position information where the agricultural machine 30 is currently located.
Next, in step S <b> 8, this position information is transmitted to the portable terminal 20 by the communication means 32 of the farm work machine 30.
On the other hand, the mobile terminal 20 to which the position information is transmitted causes the display unit 23 to display the position information on the map and stores the position information in the storage unit 24. Here, the user confirms the position information displayed on the display unit 23 to notify the police that the user is stolen other than the position where the farm equipment 30 is stored, and based on the position information. Can be tracked and easily retrieved.

  As described above, in the agricultural machine 30 including the communication unit 32 that communicates with the mobile terminal 20, the position information detection unit (GPS) 38 that detects the position information of the machine body and the door 44 that is disposed at the entrance of the driving operation unit. The door opening / closing state detecting means 42 for detecting the opening / closing state and the portable terminal 20 or the agricultural machine 30 set a theft alarm setting time, and when the door 44 is opened / closed, it is determined whether or not it is within the theft alarm setting time. Set time control means 34, and when the set time control means 34 determines that it is within the theft alarm setting time, the position information detected at that time is transmitted to the portable terminal 20 and an alarm is notified. Is done.

  As a result, when the door of the farm work machine 30 is opened and closed within the set alarm time, and the farm work machine 30 is about to be stolen, the occurrence can be detected even in a remote place. Therefore, it is possible to immediately track it and prevent the farm machine 30 from being stolen.

In step S7, the fact that the authentication code input by the worker does not match the authentication code is transmitted from the communication means 132 as an alarm signal, displayed on the display unit of the portable terminal 120, and the series of processes is terminated.
In step S4, the communication means 132 transmits that the authentication code entered by the worker matches the authentication code, and displays it on the display unit 123 of the portable terminal 120 and the display means 134 of the work vehicle.
In step S5, the power switch is turned on by the authentication, and when the operator turns on the engine start switch 148, the relay 150 is actuated to drive the cell motor serving as the engine start means 139, and in a diesel engine at a predetermined timing. A predetermined amount of fuel is injected, and the gasoline engine is ignited at a predetermined timing.

  Next, in step S6, after the engine 140 is started, work is started with a work pattern described later. When the operation is finished or the engine is stopped by stopping traveling, the fuel injection is not stopped or ignited when the stop switch (also serving as the start switch 148) or the emergency stop switch is turned on by the driver. The engine 140 is stopped and the power is turned off. When starting the engine 140 again or turning on the power, it is necessary to authenticate by inputting the authentication code as described above.

[Work pattern control]
Next, a control system for reproducing a work pattern will be described with reference to FIG. FIG. 6 is a flowchart according to this embodiment of the work pattern control system shown in FIG. First, in order to store the work pattern in the storage device of the work vehicle in advance, the operator's preference, that is, the most workable pattern is found in the work (remembering the rotation speed, gear position, etc.) When the operation is temporarily interrupted or turned around at the field end, a pattern setting screen is called on the display means 134 of the work vehicle 130 (step S1). In this state, an authentication code is input and transmitted by the input unit 122 of the portable terminal 120 (step S2), and pattern setting is performed (step S3). This authentication code input and pattern setting can also be directly input from the input means 136 of the work vehicle 130. Further, the portable terminal 120 is connected and communicated with a personal computer in advance, and the portable terminal after editing the authentication code and the work pattern with the personal computer. It can also be performed by storing it in 120 and transmitting the authentication code and work pattern.
After performing the pattern setting, when the work is finished with the pattern and the work is continued after moving to the next field (working place), the apparatus can be performed with the work pattern unless the power is turned off. Also, after the work is finished and the engine is stopped, or when it is desired to perform the same work on another day after storing, when the above-mentioned power is turned on, an authentication code is input (step S4). The pattern is also called at the same time, and can be done at the same time as the previous work at the start of the work.

  In the next step S 5, it is determined whether or not the authentication code input from the portable terminal 120 or the work vehicle 130 matches the authentication code stored in the code authentication means 146. If the determination is “YES” (if the code is authenticated), the process proceeds to step S6, and if the determination is “NO” (if the code is not authenticated), the process returns to step S4 again. By authenticating the authentication code in this way (step S5), the work pattern set by the above (specifically, the engine speed, the traveling speed, the height of the work implement, the turning up of the work implement, and the back up) ON / OFF, etc.) is automatically reproduced (step S6).

The mobile terminal 120 can also be used as a remote control for the work machine. That is, a remote control operation is called at the time of work, and a selection procedure for remotely operating the work machine 144 of the work vehicle 130 is displayed on the display unit 123 of the portable terminal 120 so that an operation input of the work machine 144 can be performed. . Specifically, a selection screen for rotating / stopping, ascending / descending, etc. of the work machine 144 is displayed, and the input unit 122 can select / input. The work machine 144 can be directly operated by the worker on the work vehicle 130 as usual, and the means of “operating on the work vehicle” can be selected and input by the input unit 122. However, priority is given to the mobile phone function.
When the operation means is input, the operation means information is transmitted to the work vehicle 130 via the communication unit 125, and the work implement control means 142 operates the work implement. Specifically, the work machine 144 is rotated / stopped, raised / lowered, and the like.

  As described above, the work vehicle 130 includes the communication unit 132 that communicates with the mobile terminal 120 and the code authentication unit 146 that performs the authentication process based on the authentication code received from the mobile terminal 120, and the power vehicle 149 is turned on / off. When the code authenticating unit 146 authenticates the authentication code from the portable terminal 120, the power source 149 is turned on. In addition, the portable terminal 120 includes a remote operation unit for the work machine 144, and the portable terminal 120 and the work vehicle 130 include a work pattern storage unit for the work machine 144. The work machine 144 has a work pattern suitable for the worker. Is configured to be operable.

  As a result, it is possible to eliminate an unprotected state where the key is left unplugged due to forgetting to remove the key or the like, and the troublesomeness of inserting and removing the key can be eliminated. Since the power source 149 can be turned on by remote operation, it is possible to prevent the battery from running out or being stolen. In addition, a dedicated remote controller for operating the work machine (discharge auger, lift device, etc.) 144 becomes unnecessary, and there is no possibility of losing the remote controller. When the work vehicle 130 can be operated by a plurality of workers, the work patterns are different for each worker. Therefore, when the work is changed, the work pattern can be easily changed and easily reproduced. It becomes easy to do.
