DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grazing livestock remote management system for accurately obtaining the position of livestock grazing on a pasture on a map of the pasture displayed on the monitoring center side.

[0002]

2. Description of the Related Art When grazing livestock such as cattle, horses, and reindeer, if the range of the pasture is very wide, the position of each livestock cannot be determined.

For this reason, there is a system in which an oscillator is attached to livestock and the position of the livestock is confirmed by relying on radio waves from the oscillator. Such a system is equipped with an airplane receiver and a position data collection device, and once every several days, turns the pasture with an airplane, collects the received radio waves from each animal, and monitors the position of the animal at a monitoring center. Was being analyzed.

In Japanese Utility Model Application Laid-Open No. 5-36383, a GPS (Global Positioning) is disclosed.
system) The position of the cow is detected using hygiene.

In the system disclosed in Japanese Utility Model Laid-Open Publication No. 5-36383, a transceiver for transmitting a current time and a current position when a radio wave from a GPS is received, an alarm generator and an electric shock device are attached to a cow.

At the monitoring center, the signal received from the cow is analyzed to determine whether or not to go from a predetermined grazing area to another grazing area. To generate an alarm sound.

[0007] In addition, if the user goes to another area even if the alarm sound is generated, an electric shock is applied to the cow using an electric shock device.

[0008] This is a system for controlling the behavior of the cow by the learning effect of the cow while performing such control at the monitoring center.

[0009]

However, a system for confirming the position of livestock by relying on radio waves from a livestock oscillator collects radio waves from livestock by airplane and confirms the position of each livestock. Therefore, there was a problem that costs were high.

In addition, since the positional data is collected only once every few days, it is not possible to grasp the behavior pattern as to whether or not the livestock is producing calves, so that the calves are often attacked by vermin. was there.

On the other hand, the system disclosed in Japanese Utility Model Laid-Open Publication No. 5-36383, which detects the position of a cow using GPS satellites, consists of simply receiving position data received from a cow and map data stored in advance (such as the Geographical Survey Institute, latitude and longitude). A comparison is made between the longitude and the indicated absolute coordinates) to determine whether to leave a predetermined area.

However, generally, the radio wave received from the GPS satellite includes a certain error. For this reason, when the position is simply determined based on the position data from the cow, there is a problem that the position is not accurate.

[0013] In particular, it is known that when a calf is born, the cow will return to the place where the calf was born.
Since the position is not accurate, the movement locus cannot be obtained accurately. For this reason, there was a problem that the calf was often attacked by vermin because the behavior of the cow when the calf was born could not be grasped.

The present invention has been made in order to solve the above-mentioned problems, and it is a grazing system that can accurately inform the position of livestock and a behavior pattern in real time from a position distant from the livestock that has been grazed.

To vector conversion. Next, based on this error vector, the position of the main point (river, tree, forest, forest, mountain, road, fence, building, etc.) of the map of the display controller 37 is moved.

Then, the new cow position data Fi (reception time 12:54:54, longitude 50 degrees 10 minutes 46 seconds, latitude 1
(50 degrees, 5 minutes, 10 seconds) is sent to the display control unit 37 to display a point image indicating the cow position on the pasture map on the screen.

Therefore, the image processing device 2 on the monitoring center 2 side
In each of the images of the map displayed in FIG. 3, the point image of the cow position data Fi is drawn on the map moved with the same error amount as the GPS error received by the livestock collar. Position is accurate.

In this case, if there is no area designation, the point image indicating the position of the cow is clustered on the whole map of the pasture as shown in FIG. 9A. Is displayed as

Next, the movement trajectory calculating section 39 reads the position of the point image in the image memory of the display control section 37 as the true cow position data Di on the map on the screen at the present time, and reads this true cow position. The data Di is stored in the locus data
The data is stored separately for each D (S6).

When there is an instruction to display the locus, the stored data of the true bovine position data corresponding to the specified cow ID is read from the moving locus data file 40.
An image connecting the positions indicated by the accumulated data is written as moving path data Ei in the image memory, and the moving path Ei
Is displayed.

Cow position data Di in step S6
Is, for example, as shown in FIG.
Minutes 30 seconds, latitude 151 degrees 10 minutes 10 seconds are stored in the movement locus data file 40. Then, it is determined whether or not the processing is completed (S7). If the processing is not completed, the process returns to step S2 to store the monitoring center position data and the cow position data while displaying the map of the pasture, while receiving the cow position data. The monitoring center position data corresponding to the time is extracted, and the position of each image on the displayed map is moved based on the error between the extracted monitoring center position data and the absolute coordinates of the monitoring center 2 to display the map. Then, a point image based on the cow position data from the cow is displayed on this map.

Further, in step S5, the code attached display determination section 43 determines whether or not an area is designated on the screen 38 and this area is 200 mm square, and notifies the display control section 37 of the determination result.

The display control unit 37 is provided with the code attached display determination unit 3
In the case where the determination result from No. 4 indicates that the designated area satisfies the predetermined condition, as shown in FIG.
G1 to G5, which are the cow ID codes corresponding to the point images, are displayed in the vicinity.

In step S5, the cattle moving locus calculating section 39 receives the moving locus display instruction and the ID (Gx) of the cow displaying the moving locus, and inputs the moving locus calculating section 39.
Assigns all accumulated data corresponding to the input cow ID up to the present from the movement locus data file 40, and moves locus data Ei connecting the positions indicated by these accumulated data.
Is created and written in the image memory of the display control unit 37. When displaying the movement trajectory, the display control unit 37 displays the trajectories in different colors.

Accordingly, as shown in FIG. 10, the moving locus of each cow up to the present in the designated area is displayed in a different color. In FIG. 10, the cow at G5 is always returning to the same place. Therefore, when the movement trajectory Ei of the movement trajectory data file 40 indicates the behavior pattern indicated by G5, the livestock situation determination unit 41 reads the individual data of G5, In this case, it is determined that the calf was born, and a message is displayed to indicate this.

As shown in FIG. 11, when it is determined that there is a cow G3 (for example, within 10 m from the fence) that has left the fence when the movement locus data file 40 is read, it is determined that there is a cow that leaves the pasture. The buzzer 42 sounds.

It is determined that the user leaves the pasture after leaving the fence because the position of each image on the screen of the image processing device is a position based on data from the GPS satellites. This is because the positions of the images have some differences.

The window shown in FIG. 9 or the screen of the moving locus or each item shown in FIG. 10 may be displayed as a window.

When the position of a cow is individually displayed, the position (latitude and longitude) from a point (building, tree, etc.) near the cow is obtained instead of the position from the monitoring center 2 to the cow. It may be displayed.

[0086] Furthermore, cattle on pastures are often grouped around leader cattle. Therefore, the image processing device 5 of the monitoring center 2 may display a different type of display for this leader cow than for other cows.

[0087]

As described above, according to the first aspect, each image of the map displayed on the image processing device on the monitoring center side is:
The livestock is moved with the same error amount as the received GPS error amount. Therefore, when a point image based on the position data of livestock is displayed on the map image on the map, the effect that the position of the livestock displayed on the screen is accurate on the screen is obtained.
