(1-2. Functional configuration of agricultural work detection control system)
FIG. 5 is a functional block diagram configured by each component of the agricultural work detection control system 1. As shown in FIG.

The microcomputer 11 of the farm work sensor unit 10 has functional units that control a program (farm work detection program) that implements the farm work detection function. As shown in FIG. 5, the microcomputer 11 includes, as functional units, an acquisition unit 11a1, a determination unit 11a2, a first setting unit 11a3, a second setting unit 11a5, a measurement unit 11a7, and a transmission unit 11a9.

The acquisition unit 11 a 1 has a function of acquiring sensing information (acceleration signal, farm work detection information) transmitted from the sensor 13 .

The first setting unit 11a3 has a function of setting the control mode of the microcomputer 11 based on the acquired farm work detection information. In this example, the first setting unit 11 a 3 switches the microcomputer 11 from sleep mode (also referred to as first control mode) to wake-up mode (also referred to as second control mode) according to an acceleration signal in the X-axis direction acquired from sensor 13 . set to

The second setting unit 11a5 has a function of setting the detection frequency of the sensor 13 according to the control mode. In this example, the second setting unit 11a5 sets the detection frequency of the sensor 13 to 1 Hz when the microcomputer 11 is in sleep mode. Alternatively, the second setting unit 11a5 sets the detection frequency of the sensor 13 so that when the microcomputer is in the wakeup mode, it is higher than the detection frequency of the sensor 13 in the sleep mode. Specifically, the second setting unit 11a5 sets the detection frequency of the sensor 13 to 1000 Hz when the microcomputer is in the wakeup mode.

The transmitting section 11 a 9 transmits various information to the receiver unit 20 via the communication section 15 .

The determination unit 11a2 has a function of determining based on the information acquired from the acquisition unit 11a1 or the measurement unit 11a7. For example, the determination unit 11a2 determines whether the sensing information acquired from the acquisition unit 11a1 satisfies a predetermined condition (also referred to as a first setting condition). The first setting condition is that the acquired acceleration signal in the X-axis direction is greater than or equal to a preset first threshold. Alternatively, the determination unit 11a2 determines whether the time information measured by the measurement unit 11a7 satisfies a predetermined condition (also referred to as a second setting condition).

The microcomputer 21 of the receiver unit 20 includes an acquisition section 21a1, a generation section 21a3, and a display control section 21a5 as functional sections.

Moreover, the generation unit 21a3 may generate field mapping information together with the GPS information. The generated various information is stored in the storage unit 23 .

The display control unit 21a5 has a function of controlling the display unit 25a to display various information generated on the display unit 25a.

(1-3. Agricultural work detection control process)
Next, farm work detection control processing in the farm work detection control system 1 will be described in detail with reference to the drawings. FIG. 6 is a flowchart showing an example of farm work detection control processing in the farm work sensor unit 10. As shown in FIG. FIG. 7 is a flowchart showing an example of farm work detection control processing in the receiver unit 20. As shown in FIG.

First, the microcomputer 11 of the agricultural work sensor unit 10 is set to sleep mode in advance when the agricultural work machine 100 is not operating (S101). The receiver unit 20 is on standby in a state in which wireless reception is possible (S201).

The sensor 13 (three-axis acceleration sensor) is set to the low power mode while the agricultural implement 100 is not operating (S103). The detection frequency of the sensor 13 is set to 1 Hz in the low power mode. In this case, sensing data is acquired intermittently (S103), so the amount of data detected by the sensor 13 can be reduced. This can prevent a large number of unnecessary information from being detected. In addition, by intermittently acquiring data, power consumption in the agricultural work sensor unit 10 can be reduced when the agricultural work machine 100 is not operating. Acquisition unit 11 a 1 acquires agricultural work detection information (specifically, an acceleration signal in the X-axis direction) detected by sensor 13 .

Next, the determination unit 11a2 determines whether the acceleration signal in the X-axis direction acquired by the acquisition unit 11a1 satisfies a predetermined condition (first setting condition) (in this example, whether it is equal to or greater than a preset first threshold value). whether) is determined (S105). The acceleration signal in the X-axis direction varies according to the operation of the rotary working unit 102, that is, the rotating operation of the tillage tines 103 provided on the rotary working unit 102 (tillage shaft 104). Therefore, when the agricultural implement 100 is not operating, the acceleration signal in the X-axis direction is less than the first threshold value (S105; No), so the process loops.

Next, when the agricultural implement 100 starts to operate, the tillage tines 103 on which the sensor 13 is arranged start to rotate, so the acceleration signal of the sensor 13 in the X-axis direction increases. As a result, if the acceleration signal in the X-axis direction is greater than or equal to the first threshold value (S105; Yes), the first setting unit 11a3 sets the microcomputer 11 to wakeup mode (also referred to as first control mode) (S107). . Further, the second setting unit 11a5 may set the detection mode of the sensor 13 from the low power mode to the normal mode in accordance with the change of the control mode of the microcomputer 11 from the sleep mode to the wakeup mode. At this time, the second setting unit 11a5 sets the detection frequency of the sensor 13 from 1 Hz corresponding to the low power mode to 1000 Hz corresponding to the normal mode (S109).

Further, when the acceleration signal of the tillage tines 103 in the X-axis direction is greater than or equal to the threshold value (S105; Yes), the control unit 11a generates tillage shaft rotation start information. The transmitter 11a9 transmits the generated tillage shaft rotation start information to the receiver unit 20 (S111). The acquisition unit 21a1 of the receiver unit 20 acquires the transmitted tillage shaft rotation start information (S203). At this time, the acquired tillage shaft rotation start information may include identification information (also referred to as a sensor ID) for identifying the sensors 13 arranged on the plurality of tillage tines. That is, it is possible to identify which sensor 13 is operating. Moreover, in the case of the sensor 13 with no battery capacity of the power supply unit 17, the acceleration signal of the sensor 13 is not transmitted. Therefore, it is possible to identify the sensor 13 whose battery has run out.

Next, in the wakeup mode, the measurement unit 11a7 determines that the acceleration signal in the X-axis direction detected by the sensor 13 at 1000 Hz no longer satisfies the first setting condition (the acceleration signal in the X-axis direction that is less than the first threshold The elapsed time (referred to as sleep time) during which the acceleration signal in the X-axis direction less than the first threshold continues to be acquired from the acquired timing is measured (S113). As for the sleep time, the measurement ends when the acceleration signal in the X-axis direction is equal to or greater than the first threshold, and the sleep time is measured again from 0 sec after the acceleration signal in the X-axis direction becomes less than the first threshold again. is started.

If the sleep time does not exceed the predetermined time (S115; No), the determination unit 11a2 determines whether the acceleration signal in the Y-axis direction among the acquired acceleration signals satisfies a predetermined condition (is it equal to or greater than the second threshold). ) is determined (S117). When the acceleration signal in the Y-axis direction is less than the second threshold (S117; No), the process returns to S115.

When the acceleration signal in the Y-axis direction is equal to or greater than the second threshold (S117; Yes), the transmitter 11a9 transmits acceleration signals in the X-axis direction, the Y-axis direction, and the Z-axis direction to the receiver unit 20 (S119). . Subsequently, the control process returns to S115.

At this time, in the receiver unit 20, when the acquisition unit 21a1 acquires the acceleration signal (S205), the generation unit 21a3 generates analysis data (S207). Furthermore, the display control unit 21a5 transmits a display instruction signal to the display unit 25a for the generated analysis data. As a result, the analysis data is displayed on the display section 25a (S209).

On the other hand, if the sleep time satisfies the second setting condition (exceeds the predetermined time) (S115; Yes), the first setting unit 11a3 sets the microcomputer 11 to the sleep mode (S121). Further, the second setting unit 11a5 sets the detection mode of the sensor 13 from the normal mode to the low power mode in accordance with the change of the control mode of the microcomputer 11 from the wakeup mode to the sleep mode. At this time, the second setting unit 11a5 sets the detection frequency of the sensor 13 from 1000 Hz corresponding to the normal mode to 1 Hz corresponding to the low power mode (S109). Subsequently, the control process returns to S101. The above is the farm work detection control process.

By using this embodiment, the sensor can detect an appropriate amount of sensing data according to the timing of farm work. Therefore, unnecessary data detected by the sensor is reduced, and the calculation load on the receiver unit 20 and the amount of data to be transmitted and received can be reduced.

Moreover, by using this embodiment, the detection frequency of the sensor 13 is changed according to the control mode of the farm work sensor unit 10 . In particular, when the microcomputer 11 is in sleep mode, the sensor detection frequency is set to be extremely low. As a result, unnecessary power consumption can be suppressed, so the agricultural work sensor unit 10 can be used for a long period of time.
