During preceding equipment 2 and rear equipment 3 are activated by actuating component 14, this ensures the personnel on ground, if truly having, position
In the safe distance from tractor 1 to avoid accident.The predetermined vehicle speed is the minimum speed that tractor is advanced on the ground
Degree.In the case where car speed is lower than predetermined vehicle speed, actuating component 14 can not be moved by operator from off-position
Position to operating position.Actuating component 14 includes switch, control stick or knob.
Predetermined vehicle speed is detected by velocity measuring device S1 to generate sensed speed signal In1.Velocity measuring device
It is sensor or global positioning system (GPS).Sensed speed signal In1 is sent to controller 12, the processing sensing of controller 12
Speed signal In1 is to determine predetermined minimum car speed.When determining predetermined vehicle speed, controller 12 generates output signal
Op1, output signal Op1 are sent to actuating component 14 so that actuating component 14 can be made to be moved to operating position from off-position.
According to the requirement of operator, actuating component 14 is moved to off-position from operating position.According to the working position of actuating component 14
It sets and off-position, actuating component 14 transmits trigger signal T to controller 12.
Controller 12 receives the PTO mechanism 16 of tractor 1 by associated sensor S2, S3 and S4 respectively, four-wheel drives
The first operative configuration and the second operative configuration of motivation structure 18 and coupling mechanism 20.Sensor S2, S3 and S4 are respectively to controller
12 transmission input signal In2, In3 and In4.Input signal In2, In3 and In4 correspond to the PTO mechanism 16 of tractor 1, four-wheel
The first operative configuration and the second operative configuration of driving mechanism 18 and coupling mechanism 20.
When actuating component 14 is at operating position, input signal In2, In3 and In4 are by the processing of controller 12 to generate pair
Output signal Op2, Op3 and the Op4 answered.Output signal Op2, Op3 and Op4 from controller 12 are respectively transmitted to corresponding
Mechanism, it is controlled motor-driven to be executed at the edge of a field such as PTO mechanism 16, four-wheel drive mechanism 18 or coupling mechanism 20.Thus, according to
The requirement of operator, when actuating component 10 at the edge of a field everywhere when operating position, PTO mechanism 16 be operated to preceding PTO and
The power-fail of PTO or deactivated afterwards, four-wheel drive mechanism 18 is disabled or deactivates, to operate tractor in two-wheel drive mode
1, and coupling mechanism 20 is operable to promote preceding equipment 2 and rear equipment 3 passes through predetermined position.
Referring to fig. 2, after the motor-driven 1c to position of position arm 1a, tractor 1 is positioned to along programme path P operation.
Programme path P is planned by automatic tracking system, or is determined by operator.It can be by means of automatic tracking mechanism (not shown)
Tractor 1 when manipulation is located at the 1c of position along programme path P in auto-steering mode.Do not intervene manually in operator
In the case where, in auto-steering mode, automatic tracking mechanism can make tractor 1 advance along programme path P.However, operation
Member can manually manipulate tractor 1 along programme path P the auto-steering mode of override tractor 1.
Fig. 4 illustrates the alternative embodiment of the actuating mechanism 10 of Fig. 3 diagram.In the alternative embodiment of actuating mechanism 10
In, as shown in figure 4, include with actuating mechanism 10 be integrally formed module 22, the module 22 be configured for from couple
The associated sensor S4 of mechanism 20 receives input signal In4, and receives trigger signal T from actuating component 14.Module 22 is suitable
According to actuating component 14 operating position and off-position, handle input signal In4, with generate sent out with by actuating component 14
The corresponding output signal In4 ' of the trigger signal T sent.Output signal In4 ' is sent to controller 12 associated with module 22
Or pilot controller 24.Output signal Op4 is with the operation of controller control mechanism 20 for the transmission control of pilot controller 24.By sensor
The input signal In2 and In3 of S2 and S3 transmission is handled by controller 12, as described above with respect to fig. 3.
Each mechanism associated with tractor 1 can also such as PTO mechanism 16, coupling mechanism 20 and four-wheel drive mechanism 18
It is operate separately by means of associated actuating component such as control stick or switch.Override (not shown) be provided with
Control signal Op2, Op3 for enabling operator's override (override) of tractor 1 to be transmitted by controller 12 or module 22 and
Op4, with the operation for controlling PTO mechanism 16, coupling mechanism 20 and four-wheel drive mechanism 18.It is specific that this can be such that operator is based on
It is required that selectively controlling the operation of PTO mechanism 16, coupling mechanism 20 or four-wheel drive mechanism 18 if truly having.
Thus, edge of a field operation control system of the invention can be such that multiple mechanisms operate by the operation of operating member 14.This
Reduce operator due to respectively activating fatigue caused by multiple mechanisms at the edge of a field.
