Description

  The present invention relates to a combine remote control system.

  Conventionally, a system for remotely controlling a combine using a portable wireless controller has been considered. However, these are based on a one-to-one relationship between a combine to be operated and a wireless controller on the driver side. Therefore, when a plurality of combiners are approaching, there is a problem in that radio interference occurs during these remote operations and malfunctions occur. For this reason, a technique is used to prevent interference with other combines by providing a characteristic signal in the radio wave transmitted and received between the control device on the combine side and the wireless controller constituting the communication relationship. .

In addition, as shown in Patent Document 1, there is a technique for displaying a combine working state on a screen of a mobile phone.

  Then, as shown in FIG. 2, on the input side of the control device 28 provided in the control unit 3, the communication device 29 that forms the communication state with the telephone line and the remote operation switch for switching the remote operation state between the valid state and the invalid state. The switch 30 is connected. Further, on the output side of the control device 29, a speed increasing relay 31 and a speed reducing relay 32 for operating the speed change electric motor 27 for tilting the speed change lever 15, and a steering hydraulic valve for operating the left and right push cylinders. The steering solenoids 33 and 34 for switching operation, the ascending solenoid 35 and the descending solenoid 36 for operating the lifting hydraulic cylinder 26, and the engine control unit 37 are connected.

  On the other hand, as shown in FIG. 3, on the input side of the control unit 41 of the mobile phone 40, the power key 42 for turning on / off the power, the cross key 43 in the cross operation direction for selecting the operation menu, and the call state A call key 44 for entering operation, a numeric keypad 45 for inputting numbers from 1 to 0, and a microphone 48 are connected. Further, a display unit 46 made of color liquid crystal, a communication control unit 47 for communicating with the nearest relay station, and a speaker 49 are connected to the output side of the control unit 41 of the cellular phone 40.

  With the above configuration, when the power key 42 of the mobile phone 40 is turned on and operated, the cross key 43 is operated to select the remote operation mode and this is switched to the valid state, the communication control is performed from the control unit 41 of the mobile phone 40. An output is made to the unit 47, a radio wave output for dial-up is made from the communication control unit 47, and this radio wave is received by the nearest relay station 50. (The conceptual diagram of this communication system is shown in FIG. 4.) When the relay station 50 transmits to the main station 51, the connection destination combine A stored in advance is specified, and the main station 51 again transmits the relay station. The signal returned to 50 is emitted from the relay station 50 as a radio wave, and the communicator 29 on the combine A side receives it. As a result, the dial-up is completed, the line is connected, and the combine A can be remotely operated. Therefore, the cellular phones 40 having different station numbers are not connected to the same combine A side. In an environment where it is necessary to perform communication between a plurality of main stations 51, the main stations 51 are connected via the Internet I so that they can communicate with each other. In this case, various information from the Internet I can be downloaded to the mobile phone 40 side and displayed on the display unit 46, and this information can be used for remote operation of the combine A. For example, a map of the workplace can be downloaded from a map information site on the Internet I and displayed on the display unit 46 of the mobile phone 40, and the operator can safely drive the combine A while viewing the map.

  In this state, when the upper side of the cross key 43 of the cellular phone 40 shown in FIG. 5 is pressed, this operation state is input from the cross key 43 to the control unit 41 and output from the control unit 41 to the communication control unit 47. A shift command signal is transmitted from the communication control unit 47 in response to the command. This signal is transmitted to the main station 51 through the relay station 50 through the above-mentioned line, and is transmitted from the main station 51 to the combine A side through the relay station 50 again. Then, when the communicator 29 on the combine A side receives this shift command signal, an output is made from the control device 28 to the speed increasing relay 31 or the speed reducing relay 32 of the speed changing electric motor 27, and the speed changing electric motor 27 forwards or reverses the speed change. The lever 15 is tilted in the front-rear direction, and the output rotation of the hydrostatic continuously variable transmission is continuously adjusted in the forward and reverse directions. Further, the tilting direction and tilting position of the shift lever 15 are operated according to the operation direction and operation time of the cross key 43 of the mobile phone 40, and when the upper side of the cross key 43 is pressed, the speed increases. The speed increasing state is continued only while this push operation is maintained. Further, when the lower side of the cross key 43 is pressed, the vehicle is decelerated, and the decelerating state is continued only while the pushing operation is continued.

  This allows the operator to arbitrarily adjust the traveling speed of the combine A when the operator leaves the combine A and performs remote control when loading and unloading the combine A onto the truck bed, or when moving the truck, running on slopes, etc. Can improve safety.

  6 is connected to the input side of the control unit 41 of the mobile phone 40, and a dedicated vehicle speed shift operation button consisting of a vehicle speed increase button 52 and a vehicle speed decrease button 53 is connected. As shown, the vehicle speed may be changed by a constant speed each time the buttons 52 and 53 are pressed once. Thereby, the vehicle speed of the combine A can be accurately adjusted.

  Further, as shown in FIG. 7, a neutral button 54 is provided at the center of the cross key 43 of the mobile phone 40, and the neutral button 54 is connected to the input side of the control unit 41 so that the same communication system as described above is provided. Thus, when the neutral button 54 is pushed, whatever the traveling speed of the combine A is output to the deceleration relay 32, the shifting electric motor 27 is operated to the deceleration side, and the combine A travels. You may comprise so that it may stop. Thereby, driving | running | working can be stopped reliably and rapidly at the time of emergency, and safety can be improved.

  In addition, by selectively pressing the left and right sides of the cross key 43, the output direction to the speed increasing relay 31 or the speed reducing relay 32 is alternatively selected and advanced by the same communication system as described above. It may be configured that the traveling speed in the selected forward traveling or backward traveling is changed by switching between traveling or reverse traveling and pressing the upper and lower sides of the cross key 43 in this state.

  When the power key 42 of the cellular phone 40 is pressed, the engine control unit 37 stops the fuel injection of the engine 12 and stops the engine 12 and presses the call key 44 by the same communication system as described above. When operated, the engine control unit 37 may rotate the cell motor and start fuel injection to start the engine 12. Accordingly, an emergency stop can be performed by remote operation, and a trouble caused by carelessness of the operator can be monitored by a remote assistant, and the engine 12 can be stopped according to the situation, thereby improving safety.

  In addition, by pressing the power key 42 of the cellular phone 40, the traveling electric motor 27 for shifting is output to the speed reducing relay 32 regardless of the traveling speed of the combine A by any communication system similar to the above. May be configured to stop the traveling of the combine A by operating to the deceleration side. Thereby, driving | running | working can be stopped reliably and rapidly at the time of emergency, and safety can be improved.

  Further, by pressing the upper or lower side of the cross key 43 of the cellular phone 40, an output is made from the control device 28 to the raising solenoid 35 or the lowering solenoid 36 by a communication system similar to the above, and hydraulic pressure is applied. You may comprise so that the cylinder 26 may be expanded-contracted and the cutting part 11 may raise / lower by this. That is, only while the upper side of the cross key 43 is being pressed, an output is made from the control device 28 to the raising solenoid 35 and the hydraulic cylinder 26 is extended, whereby the cutting portion 11 is raised. Further, only while the lower side of the cross key 43 is pressed, an output is made from the control device 28 to the descending solenoid 36 and the hydraulic cylinder 26 is shortened, whereby the cutting unit 11 is lowered. Thereby, when the combine A is loaded and unloaded on the truck bed, or when the operator is remotely operated away from the combine A, such as the narrowing of the combine A, traveling on an inclined ground, etc., the cutting unit 11 can be adjusted up and down. It is possible to improve safety and operability.

  Further, by selectively pressing the left and right sides of the cross key 43 of the mobile phone 40, the left steering solenoid 33 or the right steering solenoid is controlled from the control device 28 by the same communication system as described above. 34, the oil feeding direction from the steering hydraulic valve is switched, and the left and right side push cylinders are operated. By the operation of the push cylinders, the left and right side clutch mechanisms in the traveling mission case 6 are operated. One of the left and right of them may be detached from the center gear, and the airframe may be turned to this side. As a result, when the combine A is loaded and unloaded on the truck bed, or when the operator remotely operates the combine A away from the combine A, such as when the combine A is moved down or traveled on a sloping ground, the travel direction of the combine A is controlled left and right. Safety and operability can be improved. In addition, side brakes are configured on the left and right outer sides of the side clutch, and at the time of steering, either the left or right side clutch is disconnected and the drive wheel 7 on the side where the side clutch is disconnected is braked. Also good.

  In addition, rotational speed sensors for detecting the rotational speeds of the left and right drive wheels 7 and 7 are provided independently on the left and right sides, and the detection results by the left and right rotational speed sensors are obtained from the control device 28 on the combine A side in the same manner as described above. The information may be sent to the control unit 41 on the mobile phone 40 side through the communication system and displayed on the display unit 46 connected to the control unit 41 as shown in FIG. 7 (G in the drawing). Thereby, the speed difference between the left and right drive wheels 7 and 7 can be confirmed from a remote location and the size of the turning radius can be grasped. Further, the traveling speed of the combine A may be displayed on the display unit 46 (S in the drawing) based on the detection results of the rotational speed sensors on both the left and right sides. In addition, as shown in FIG. 8, the traveling speed of the combine A may be displayed graphically using a battery remaining amount display unit E provided as a function of the mobile phone 40. Further, as shown in FIG. 9, the traveling speed of the combine A may be displayed using a volume display unit V provided as a function of the mobile phone 40. In addition, as shown in FIG. 10, the forward traveling speed and the backward traveling speed of the combine A may be displayed graphically on the display unit 46 of the mobile phone 40 as opposite bars. The forward travel speed and the reverse travel speed can be easily distinguished. In the graphic display of FIG. 10, the bar F for displaying the forward travel speed and the bar R for displaying the reverse travel speed may be displayed in different colors. The speed and the reverse travel speed can be more easily identified.

  Note that, as described above, the combine A is steered by the left and right tilting operation of the operation lever 14 provided in the control unit 3, and the cutting unit 11 is adjusted up and down by the forward and backward tilting operation of the operation lever 14. The configuration is such that the combine A is steered by selectively pressing the left and right sides of the cross key 43 of the mobile phone 40 and the cutting unit 11 is adjusted up and down by alternatively pressing the upper and lower sides of the cross key 43. . That is, since the operation lever 14 provided in the control unit 3 of the combine A and the operation direction of the cross key 43 of the mobile phone 40 coincide with each other, the operation can be easily performed, and erroneous operations are reduced.

  In addition, the auxiliary transmission mechanism of the combine A is provided with a sensor for detecting a shift switching position of the auxiliary transmission mechanism, and various remote operations by the cellular phone 40 can be performed only when the low speed state is detected by the sensor. You may comprise so that it may be in a state. That is, when it is detected by the sensor that the auxiliary transmission mechanism has been switched to a state other than the low speed, even if an operation command is issued from the control unit 41 on the mobile phone 40 side through the same communication system as described above, From the control device 28 on the combine A side to the speed increasing relay 31, the speed reducing relay 32, the left steering solenoid 33, the right steering solenoid 34, the engine control unit 37, the raising solenoid 35, the lowering solenoid 36, and the like. This is to prevent output. Accordingly, when the auxiliary transmission mechanism is switched to the high speed position and the combine A travels at a high speed, the mobile phone 40 cannot be remotely operated, and avoids the fall of the combine A during high speed travel or deviation from the course. be able to. When the travel speed of the combine A is changed with the cross key 43 of the mobile phone 40, the output from the control device 28 on the combine A side to the speed increasing relay 31 is suppressed, and the travel speed of the combine A is set to the set speed. You may comprise so that it may not speed up more than the above.

  Further, an engine rotation control motor may be connected to the output side of the control device 28 on the combine A side so that the engine speed of the combine A can be adjusted by operating the cross key 43 of the mobile phone 40. In this case, even if the cross key 43 is continuously operated, the speed increasing output from the control device 28 to the engine rotation control motor is controlled so that the engine rotation speed does not exceed the set rotation speed. As a result, when adjusting the engine speed by remote control, it is possible to avoid the danger that the engine speed increases abnormally and the combine A runs away.

  Further, in the configuration in which the traveling speed of the combine A is displayed on the display unit 46 of the mobile phone 40 as described above, the traveling shift operation and the steering operation of the combine A, the lifting operation of the cutting unit 11, When an engine start operation or an engine stop operation is performed, an alarm on the combine A side generates an alarm according to an output from the control device 28, and a warning light provided at a high place of the combine A may be turned on. . Thereby, a third party can detect that the combine A is in a remote operation state, and safety can be improved. The warning lamp is effective when provided at the tip of the discharge auger 20 of the grain storage unit 5 or the like.

  Further, in the remote operation state, the alarm is provided from the combiner A side alarm device as described above, and the alarm is also issued from the speaker 49 of the mobile phone 40. Further, as the traveling speed of the combine A increases. The alarm sound volume may be increased. As a result, a third party can perceive a change in the traveling speed due to a change in the volume of the alarm sound, and safety is improved.

  Further, the cross key 43 of the mobile phone 40 in FIG. 5 may be configured to have the same function as the turning / lifting operation lever of the discharge auger 20 provided on the control unit 3 side of the combine A.

A discharge auger raising / lowering command signal is transmitted from. This signal is transmitted to the main station 51 through the relay station 50 through the above-mentioned line, and is transmitted from the main station 51 to the combine A side through the relay station 50 again. When the communicator 29 on the combine A side receives this discharge auger up / down command signal, an output is made from the control device 28 to the operation solenoid of the lift drive cylinder, and the discharge auger 20 is moved by the expansion / contraction operation of the lift drive cylinder. Move up and down.

  On the other hand, when the right or left side of the cross key 43 is pressed, this operation state is input from the cross key 43 to the control unit 41, and from the communication control unit 47 according to an output command from the control unit 41 to the communication control unit 47. A discharge auger turning command signal is transmitted. This signal is transmitted to the main station 51 through the relay station 50 through the above-mentioned line, and is transmitted from the main station 51 to the combine A side through the relay station 50 again.
