It is configured to detect and transmit it to the controller 9 serving as control means. As a result, the controller 9 outputs a switching command to the switching control valve, and supplies and discharges pressure oil to and from the cylinder 16 to move the cutter housing 15 up and down.
[0013]
A PTO lever 2 for setting the rotation of the PTO shaft 19 is provided below the cockpit 20 so that the rotation of the coaxial 19 is switched between LL speed, L speed, M speed, and H speed in four stages. I have.
Further, in front of the cockpit 20, a steering handle 25 for steering the left and right front wheels 3F and a meter panel 26 for displaying a working state or a running state are provided.
[0014]
As shown in FIG. 3, the meter panel 26 is provided with an engine water temperature gauge 30 and a fuel gauge 31 on the front left side, a tachometer 32 at the center, and a liquid crystal monitor 8 serving as a display unit on the right side. Has a receiving seat having a concave portion 36 for fixing the mobile phone 7 (communication device), and a communication connector 37 for connecting to the controller 9 is provided on the bottom surface of the concave portion.
[0015]
The communication device may have another form such as a permanent installation of a communication modem in a meter panel instead of the detachable mobile phone 7.
In the inside of the meter panel, a GPS receiver 5 serving as a vehicle position detection sensor, a gyro sensor 34, a thermometer 6a detecting temperature as weather information around the vehicle, a hygrometer 6b detecting humidity, and further, A wind speed sensor 6c is provided, and these detected values are transmitted to the controller 9 and displayed on the liquid crystal monitor 8.
[0016]
Next, the controller 9 will be described with reference to FIG.
The controller is control means of the present invention, and includes therein a CPU for processing various information, an EEPROM for storing a control program according to the present invention, a RAM for temporarily reading and storing various sensor values and a control program, and the like. Is provided.
[0017]
Then, a potentiometer 21s, a thermometer 6a, a hygrometer 6b, a wind speed sensor 6c, a GPS receiver 5, a gyro sensor 34, a vehicle speed sensor 14, a PTO rotation sensor 19s, and the like are connected to this input unit. The output unit is connected to solenoids 40u and 40d of a switching control valve for raising and lowering the cutter housing 15, a liquid crystal monitor 8, an alarm buzzer 41, various pilot lamps 42, and the like.
[0018]
The controller 9 is provided with the communication connector 37 so that the controller 9 can be connected to external data, for example, a site published on the Internet or a database of an information service company that can be connected via a dedicated line, through the mobile phone 7.
In the lawn mower configured as described above, as shown in FIG. 5, control for instructing a set value is performed.
[0019]
First, when the engine key switch of the riding lawn mower 10 is turned on, the engine 12 is driven and the controller 9 is energized. Then, the controller 9 reads the setting information of various sensors and setting devices on the vehicle, and determines the current position of the vehicle by the GPS receiver. In this case, as shown in FIG. 6, the information is displayed on the map of the liquid crystal monitor 8. Further, current weather information around the vehicle is displayed from the temperature sensor 6a, the hygrometer 6b, and the like. (STEP 1-4)
Next, it is determined whether or not the mobile phone 7 is connected. If the determination is YES, first, time information is obtained from a database on the Internet set in advance, and a clock of the vehicle is set.
[0020]
Thereby, even when the riding lawn mower 10 is stored for a long period of time and the time or date is shifted, the accuracy is improved each time the connection to the database is made, and malfunction of control using time such as weather information described later is prevented. Can be prevented.
Then, after connecting to the database having weather information, past weather information before a predetermined time, for example, weather information such as temperature, humidity, rainfall, and weather 12 hours before is fetched (STEP 8).
[0021]
The current weather information and the weather information received from the database are compared and displayed, and the recommended work speed and fan speed are set based on the rules set for each model by predicting the moisture state of the turf currently working from these values. Is displayed on the liquid crystal monitor 8.
[0022]
Here, as shown in FIG. 1, the standard working speed is 10 km / h, the PTO rotation is M speed (pattern A), and conditions under which turfgrass is assumed to contain a lot of moisture, for example, the past 12 hours ago Of the weather information, if there is a rainfall (or the weather is "rain") and humidity is still detected at a predetermined value or more, the pattern B is displayed, that is, a value obtained by subtracting the vehicle speed by a predetermined ratio. Is displayed to indicate that the H speed of the PTO rotation is set.
[0023]
In addition, even if the rainfall amount is present (or the weather is “rain”) 12 hours ago, if the current humidity is equal to or less than a predetermined value, the value of the pattern A is displayed as a standard state.
On the other hand, if the rainfall in the past 12 hours is 0 (or the weather is “fine”) and the current humidity is lower than the predetermined value, it is assumed that the turfgrass can perform high-speed work in a state that does not contain much moisture, The value of the pattern C, that is, the value obtained by adding the vehicle speed by a predetermined ratio is displayed, and the PTO rotation is displayed to be set to the H speed.
[0024]
Thus, even when an operator unfamiliar with the work mows the lawn using the lawnmower 10, an appropriate amount of work, that is, the air flow rate of the fan 1 and the work speed can be quickly obtained, and the work can be started quickly. be able to. In addition, the setting position and the shift position are erroneously set, the turfgrass is clogged by insufficient air volume, and the operation is performed at an excessively low speed and the operation with low fuel consumption is performed, thereby not impairing the operation efficiency.
[0025]
When the PTO speed is set automatically, an actuator is provided on the PTO shift lever, and the actuator is switched to a shift position so as to reach the recommended value in response to an energization command from the controller. When the shift position is automatically set, an actuator is provided on the trunnion shaft of the HST transmission 13 or the traveling shift lever 4, and the actuator is set to the set value specified by an energization command of the controller. The shift position is adjusted as follows.
[0026]
Further, the work amount (air volume) and the traveling speed instruction value may be calculated by different formulas in consideration of other weather information, for example, the magnitude of the wind speed value and the temperature level, or may be selected by a map. .
Next, the liquid crystal monitor 8 will be described in detail.
[0027]
As described above, the meter panel 26 is provided with the concave portion 36 for fitting and fixing the mobile phone 7, and the mobile phone 37 is connected to the communication connector 37 in the concave portion 36. However, since the telephone 7 is located far away, there is a problem that it is difficult to see the incoming call display of the telephone, and it is difficult to hear the ringing tone due to the noise of the engine 12 and the fan 1.
[0028]
Therefore, in the meter panel 26, the cord 42 connected to the communication connector 37 is configured in a retractable manner in the meter panel 26, and is configured to be detachable together with the telephone 7 from the concave portion 36, and the telephone 7 receives an incoming call. If there is, the liquid crystal monitor 8 is configured to display the incoming state as an interruption screen from the state of the screen at the time of work (FIG. 7). Further, during a call, as shown in FIG. 8, information on the mobile phone, for example, a call time is displayed on the monitor 8 of the vehicle.
[0029]
Thus, if there is an incoming call on the telephone 7 even during work, the operator can take it without missing it, and can make a call without disconnecting the communication connector 37 during a call.
As another form of the invention, as shown in FIG. 9, a portable information terminal 7 'that can be shared by other work vehicles may be used as a communication device.
[0030]
The difference from the portable telephone 7 is that the portable terminal 7 'has a storage device for storing work data for each model, a monitor of a touch panel type, and a local LAN line, that is, a database having weather information. A configuration in which a wireless communication device to be connected is provided and an infrared communication device is provided, and the portable terminal device 7 'is fixed to the meter panel 26, that is, communicates with the controller 9 of the vehicle by approaching the controller 9 of the vehicle. It has become.
[0031]
As a result, as described above, it is not necessary to connect to the connector 37 on the controller 9 side, so that work data can be taken in, and work information can be viewed even when the terminal 7 ′ is removed from the vehicle. .
