JP 2022-78440 A

It is difficult for one work manager to issue appropriate work instructions while receiving reports from multiple work vehicles because the work environment and work progress status of each work vehicle changes.

An object of the present invention is to enable one work manager to receive work progress reports from a plurality of work vehicles and issue work instructions without confusion.

The above problems of the present invention are solved by the following technical means.

The invention of claim 1 provides a control management system for multiple work vehicles in which a management terminal 7 receives work progress reports from a plurality of automatically traveling work vehicles 1 and instructs the work. This control management system for a plurality of work vehicles is characterized by displaying positions and work progress reports on a management terminal 7 at regular time intervals.

The invention of claim 2 is a control and management system for multiple work vehicles as described in claim 1, characterized in that it manages the consumables carried by each work vehicle 1, and when the remaining amount of the consumables reaches a predetermined amount, displays the work vehicle 1 preferentially on the management terminal 7.

The invention of claim 3 is a control and management system for multiple work vehicles as described in claim 1 or claim 2, characterized in that each work vehicle 1 holds a work plan, and the work progress status of a work vehicle 1 that deviates greatly from the work plan is preferentially displayed on the management terminal 7.

In the invention of claim 1, the manager checks the work progress of each work vehicle 1 while looking at the screen of the management terminal 7, but while the work is being performed normally, the manager looks at the screen of the management terminal 7. The work progress status of each work vehicle 1 can be sequentially displayed and understood on the screen just by being there, so management can be performed easily.

In the invention of claim 2, when the work vehicle 1 is performing work using consumables, if the consumables are running low and it is necessary to add them, the work vehicle 1 has priority over the screen of the management terminal 7. Since it is displayed, the administrator can easily notice and instruct the replenishment of consumables, eliminating work stagnation due to lack of consumables and continuing efficient work.

In the invention of claim 3, each working vehicle 1 proceeds with the work according to the work plan in the field in charge, but if the progress of the work deviates from the work plan, that working vehicle 1 is prioritized and displayed on the screen of the management terminal 7. As a result, the manager can plan the movement to the next field and adjust the work speed so that the work completion time coincides with that of other work vehicles 1, making the management of the work vehicle 1 more efficient. can be done.

1 is a schematic explanatory diagram of a work vehicle control management system according to an embodiment of the present invention. It is a control block diagram of the work vehicle control management system same as the above. It is a top view of the working state of the multiple work vehicle of the system same as the above. FIG. 2 is a diagram showing a screen of a management terminal of the system.

EMBODIMENT OF THE INVENTION Hereinafter, regarding an embodiment of the present invention, the configuration and operation of a control management system for multiple work vehicles will be specifically described with reference to the drawings.

Figure 1 is an overview diagram of a control management system for multiple work vehicles, showing three tractors 1a, 1b, and 1c as work vehicles 1, and data transmitted by each of the tractors 1a, 1b, and 1c is transmitted via the cloud 30 to a work machine management server 6 and a management terminal 7 held by the work manager.

Tractors 1a, 1b, and 1c are work vehicles that can perform tilling, plowing, leveling, sowing, fertilizing, etc. by changing the implements attached to the rear.

In FIG. 2, the control unit Ca of the tractor 1 as an example of a control means, the control unit Cb of the server 6, and the control unit Cc of the management terminal (tablet terminal) have an input/output interface I/O for inputting and outputting data from and to the outside. The control units Ca to Cc also have a ROM (read-only memory) in which programs and information for performing necessary processing are stored. The control units Ca to Cc also have a RAM (random access memory) for temporarily storing necessary data. The control units Ca to Cc also have a CPU (central processing unit) that performs processing according to the programs stored in the ROM or the like. In other words, the control units Ca to Cc in the embodiment are configured as information processing devices, so-called computers. Thus, the control units Ca to Cc can realize various functions by executing programs stored in the ROM or the like.

The control unit Ca of the tractor 1 receives data from an obstacle sensor 2, a GPS device 3, a consumables sensor 8 indicating the remaining amount of consumables such as seeds, fertilizers, and fuel, and other data input members (not shown). Ru. A plurality of obstacle sensors 2 are installed on the tractor 1 and are configured to be able to detect surrounding obstacles such as in front and on the sides. Note that the obstacle sensor 2 can be any conventionally known sensor, such as one that uses light reflection, one that uses sound waves, or one that detects obstacles by image analysis using a camera. Moreover, the positioning device 3 is a GPS device as an example, and can measure the position of the aircraft through communication with GPS satellites.

The control unit Ca of the tractor 1 outputs control signals to the engine 11, the handle 12, the brake 13, the work equipment 14, and other controlled elements (not shown) of the tractor 1.

Furthermore, the control unit Ca of the tractor 1 has the following functions (functional means, program module). The obstacle detection means C1 detects obstacles based on the detection results of the obstacle sensor 2. The positioning means C2 measures the position of the tractor 1 based on the positioning result of the GPS device 3. The communication means C3 transmits and receives data, that is, communicates with the server 6. The communication means C3 of the embodiment transmits the detection results of obstacles, position information of the tractor 1, and the status of the tractor 1 (working, moving, stopped, work progress, etc.) to the server 6. , the location information of the field where the next work will be performed, the work area and work contents in the field, information on movement and stopping instructions, etc. are received from the server 6.

The traveling control means C4 includes a deviation determining means C4A, and controls the engine 11, handle 12, brake 13, etc. of the tractor 1 to control the traveling of the tractor 1.

The travel control means C4 of the embodiment controls the tractor to move to the target farm field 9 along the movement route 22 transmitted from the server 6 when an instruction to move to the target farm field 9 is given from the server 6. 1 (inter-field movement mode). Further, when an instruction to work in the field 9 is given from the server 6, the tractor 1 is controlled to travel along the work route 23 transmitted from the server 6 (work mode). When the server 6 instructs the tractor 1 to stop and wait, the tractor 1 is stopped (standby mode). Note that when the server 6 instructs the tractor 1 to move to a specific standby position 24 and wait, the tractor 1 is moved to the standby position 24 and then stopped. In addition, when the obstacle detection means C1 detects an obstacle, the travel control means C4 of the embodiment stops the tractor 1 (abnormal stop, emergency stop) and makes it stand by on the spot (abnormal stop mode). ).

The deviation determining means C4A determines whether the tractor 1 has deviated from the movement route 22 or the work route 23, which are examples of predetermined routes.

The work machine control means C5 controls the work machine to perform work in the field 9. The work machine control means C5 of the embodiment operates the work machine to perform work when the tractor 1 enters the field 9, which is transmitted from the server 6. When the tractor 1 moves outside the work area 25, the work machine is stopped. In addition, when the working machine is used for tilling, plowing, etc., the working machine is lowered when working, and raised when not working. Note that the work machine control means C5 of the embodiment stops the work machine (abnormal stop, emergency stop) when the obstacle detection means C1 detects an obstacle.

The control unit Cc of the management terminal 7 receives signals from a screen (touch panel) 7a, which is an example of a display unit and an example of an input unit, and other signal input members (not shown). The touch panel 7a detects the position touched by the operator's finger.

The control unit Cc of the management terminal 7 outputs control signals to the touch panel 7a and other controlled elements (not shown). The touch panel 7a displays an image in response to a control signal transmitted from the server 6 or the control unit Cc.

The display control means C11 controls the touch panel 7a to display an image. As shown in FIG. 4, the touch panel 7a displays images showing the working positions and working conditions of each tractor 1a, 1b, 1c, and can enlarge the touched image or enlarge the tractors 1a, 1b, 1c in an emergency. Display images for setting the work plan of tractor 1 (field to be worked on, content of work, scope of work, work route, etc.), or display priority display of tractor 1 in an abnormal situation such as abnormal stoppage. or

In addition, when the consumables sensor 8 of each tractor 1a, 1b, 1c detects a decrease in the remaining amount, the tractor 1 is enlarged and displayed, and the progress of the work plan in the field 9 input to each tractor 1a, 1b, 1c is displayed. The situation is managed and when the work is about to be completed earlier than other tractors 1, an enlarged priority display is given.

The administrator who monitors the management terminal 7 instructs the tractor 1 that displays a decrease in consumables to supply consumables, and instructs the tractor 1 whose work is progressing too quickly to slow down its work speed. or instruct preparations for moving to the next planned field 9. Furthermore, if there is no planned field for work, an instruction may be given to slow down the work speed of other tractors 1 in accordance with the work completion time of the tractor 1 with the slowest work progress.

In addition, the conditions for interrupt display on the touch panel 7a include when a person approaches within 30 meters of the tractor 1, when the working speed changes by more than 10% of the set speed, and when the spraying is performed while sowing or fertilizing. If the fuel consumption changes by more than 10% from the set value, if the fuel consumption changes by more than 10%, if the engine temperature becomes overheated, or if the engine exhaust gas temperature becomes abnormally high, , when the engine speed becomes abnormally high, when the travel route deviates from the planned work route 23, or when traveling between crops for pest control, etc., the spray width may fluctuate beyond the setting. If an interrupt condition occurs in a plurality of tractors 1, those tractors 1 are displayed alternately, and all tractors 1 with a high degree of urgency are instructed to stop.

In addition, if multiple interrupt conditions occur on one tractor 1 or an error occurs in the control device, the tractor will automatically stop traveling.

Furthermore, an arrangement may be made in which the interrupt display can be set on the management terminal 7, and a warning may be issued if an emergency situation occurs when the display is canceled. If the warning is ignored for a predetermined period of time, the tractor 1 will automatically stop running.

When the manager receives the warning and determines that there is no problem and sends the message, the tractor 1 continues its work and returns to the sequential display at predetermined intervals. If there is no problem, interrupt display is not performed for a predetermined period of time.

If a failure occurs in Tractor 1, the stopped Tractor 1 will be sent to tow it, but if there is no Tractor 1 that is not working, the tractor 1 that is working nearby will automatically interrupt its work and start towing. make them go to
