  The above-described conventional technology controls the working unit of the fertilizer spreader based on the current position information output from the GPS receiver, and controls the working unit by the GPS receiver and the GPS reception signal for each working unit. Since it is necessary to equip the apparatus, there is a problem that the working machine becomes expensive. And since this apparatus cannot be externally attached to an existing machine, even if you own a fertilizer spreader, you need to purchase the fertilizer spreader itself again.

  In addition, the above-mentioned conventional technology is a technology related to a fertilizer spreader (broadcaster) that is attached to a traveling vehicle and is suitable for full-scale spraying, and is intentionally applied to the application of soil improver and chemical fertilizer to the field before crop cultivation. If it is used for partial topdressing that is applied to the growth variation after growing the crop, the crop is damaged by the traveling vehicle. Also, in a paddy paddy field, the traveling vehicle may sink due to its own weight, making it impossible to travel.

  On the other hand, in direct sowing cultivation of large-compartment paddy fields, there may be a variation in growth depending on the location in the field due to unevenness of the geological force, etc., and grasping such a variation in growth by the normalized vegetation index (NDVI) etc. Is possible. However, a working machine suitable for performing partial topdressing at a specific position in the field has not yet been developed based on a growth map by NDVI or the like.

  In addition, not only topdressing after growth, but in large-compartment fields, operations such as weeding and chemical spraying may be performed in partial areas within the field. There is a need for a general-purpose work assistance device that can perform work.

  This invention makes it a subject to cope with such a situation. In other words, using an existing working machine that does not have an expensive control device, it is possible to accurately perform partial topdressing that is performed for growth variations after crop growth, and work after grasping the appropriate work position It is an object of the present invention to provide a general-purpose work assisting device that can perform the operation at low cost.

In order to solve such a problem, a work position indicating device according to the present invention has the following configuration.
A GPS receiver that outputs position information of the current position as needed, information storage means that stores position information of a work target area partially set in the work area, and a position of the current position that is output by the GPS receiver Comparing the information with the position information of the work area, the processing means for outputting whether or not the current position is within the work area, and the current position is operated by the output of the calculation processing means A work position indicating device comprising: an informing means for informing that the area is within the target area.

  The present invention having such features can accurately perform partial topdressing performed on the growth variation after crop growth using an existing working machine that does not include an expensive control device. In addition, a general-purpose work assistance device that can perform work after grasping an appropriate work position can be provided at low cost.

As shown in FIG. 1A, a work position indicating device 1 according to an embodiment of the present invention includes a GPS receiver 2, an information storage unit 3, a calculation processing unit 4, and a notification unit 5 as a basic configuration. The information storage means 3 and the arithmetic processing means 4 here can be integrally mounted on the microcomputer chip.

  The GPS receiver 2 receives radio waves from a plurality of GPS sanitations and outputs the current position at the current time as needed. The information storage means 3 is a storage medium such as a memory, and stores position information of a work target area partially set in the work section. The arithmetic processing means 4 is a control unit (for example, a CPU) that performs various arithmetic processes according to an incorporated program, and the work target area in which the information storage means 3 stores the position information of the current position output by the GPS receiver 2. Whether the current position is within the work area or not is output.

As shown in FIG.1 (c), it equips the outer side of the housing | casing 1A.

  FIG. 2 shows a setting example of work target areas S1, S2, S3, S4, S5, S6,... Partially set in the work section S. The work section S here is, for example, a field of a large section paddy field surrounded by the road R, and the work target areas S1, S2, S3, S4, S5, S6, etc. are normalized vegetation indices (NDVI) and the like. It is the additional fertilization work area specified in the work section S based on the growth map by.

  One work target area S1 is set by an area surrounded by three or more point positions, for example, as shown in FIG. In the example shown in FIG. 3, four point positions P1 (X1, Y1), P2 (X2, Y2), P3 (X3, Y3), P4 (X4) represented by the coordinate position information of (latitude, longitude) are used. The area surrounded by Y4) is defined as one work target area S1.

  In this work target area S1, the level of the amount of fertilizer to be additionally fertilized can be set. For the position information of each work target area S1, the level of fertilization amount in each work target area S1 is set in consideration of the growth unevenness indicated by the growth map based on the normalized vegetation index (NDVI). The fertilizer application level can be stored in the information storage means 3 in association with the position information of the work area S1.

  The work position indicating device 1 determines whether or not the current position T (Xt, Yt) at the time t output from the GPS receiver 2 is within the work target area S1, and as shown in FIG. When the current position T (Xt, Yt) is not within the work target area S1, the notification means 5 does not perform the notification operation, and the current position T ′ (Xt ′, Yt ′) at time t ′ is the work target. When entering the zone S1, a notification operation of the notification means 5 is executed.

  FIG. 4 shows the operation of the arithmetic processing means 4 of the work position indicating device 1. The arithmetic processing means 4 is driven by a power source of a battery (dry cell) (not shown) provided in the housing 1A. The operation is started when the power is turned on, the position information T of the current position at the current time is acquired from the GPS receiver 2 (STEP 1), and then the positions of the work target areas S1, S2,. An operation of acquiring information is performed (STEP 2), and the position information T of the current position is compared with the position information of the work target areas S1, S2,... To determine whether the current position is within the work target areas S1, S2,. (STEP 3). If the current position does not fall within the work target area S1, S2,... (STEP3: “NO”), the operations of STEP1 to STEP3 are repeated every set time.

  Then, the position information T of the current position is compared with the position information of the work target areas S1, S2,... And if the current position falls within the work target areas S1, S2,. ), A signal for operating the notification means 5 is output (STEP 4). At this time, when the level of fertilization amount is set in the work target areas S1, S2,..., The notification unit 5 performs different notifications according to the level of the fertilization amount. Thereafter, when the work is continued (STEP 5: “YES”), STEPs 1 to 5 are repeated, and when the work is not continued (power is off) (STEP 5: “NO”), the operation is terminated.

  FIG. 5 shows another example of the operation of the arithmetic processing means 4 of the work position indicating device 1. In this example, when the position information of the current position output from the GPS receiver 2 enters the work section S of the large section, the work position instruction apparatus 1 performs primary notification and the GPS receiver 2 outputs the information. When the position information of the current position enters the work target areas S1, S2,.

  In this example, the operation is started when the power is turned on, the position information T of the current position at the current time is acquired from the GPS receiver 2 (STEP 10), and then the position information of the work section S from the information storage means 3 Is acquired (STEP 11), and the position information T of the current position is compared with the position information of the work section S to determine whether or not the current position is within the work section S (STEP 12). If the current position is not within the work section S (STEP 12: “NO”), the operations of STEP 10 to STEP 12 are repeated every set time.

  Then, the position information T of the current position and the position information of the work section S are compared, and when the current position enters the work section S (STE21: “YES”), the primary notification means in the notification means 5 A signal for operating is output (STEP 13). After that, the operation of acquiring the position information T of the current position at the current time from the GPS receiver 2 is performed (STEP 14), and then the position information of the work target areas S1, S2,. (STEP 15), the position information T of the current position is compared with the position information of the work target areas S1, S2,... To determine whether the current position is within the work target areas S1, S2,. Perform (STEP 16). If the current position does not fall within the work target area S1, S2,... (STEP 16: “NO”), the operations of STEP 10 to STEP 16 are repeated every set time.

  Then, the position information T of the current position and the position information of the work target areas S1, S2,... Are compared, and when the current position falls within the work sections S1, S2,... (STE16: “YES”) Then, a signal for operating the secondary notification means in the notification means 5 is output (STEP 17). Thereafter, when the work is continued (STEP 18: “YES”), STEPs 10 to 18 are repeated, and when the work is not continued (power OFF) (STEP 18: “NO”), the operation is terminated.

  Here, the primary notification and the secondary notification can be executed by notification using different notification means, for example, notification by light emission (light emission) and notification by sound generation, or light emission by primary notification. It can also be executed by operating the same notification means in different forms, such as turning on the element and blinking the light emitting element by secondary notification.
