The control assembly 300 is a hand-held remote control that can control the forward, reverse, left and right turns of the chassis longitudinal frame 102, the ignition and extinction of the engine 205, and the adjustment of the size of the engine throttle 205b. Meanwhile, the remote control output channels are reserved for standby, and besides the 2 paths of digital channels and the 1 path of analog channels, 4 paths of load digital channels and 2 paths of analog channels are reserved for expanding equipment.
Preferably, the remote control is preferably in a PWM control mode, the signal transmission frequency is 2.4GHz, the frequency band signal can effectively prevent the interference of common signals, the transmission speed is high, the distance is long, and the work of the remote control crawler mower can be effectively controlled within the distance of 500 meters.
Referring to fig. 1 to 4, the control method of the remote control crawler chassis of the present invention includes the remote control crawler chassis, and indirectly controls the functions of forward, backward, left turn, and right turn of the chassis longitudinal frame 102 by controlling analog output of the throttle rocker and the direction rocker through a hand-held remote control.
The hand-held remote control comprises three parts, namely a radio transmitter, a receiver and an actuator. The transmitter mainly comprises a coding circuit and a transmitting circuit. The coding circuit is controlled by a manipulator (a manipulation switch or a potentiometer on a handheld remote control, etc.), and the manipulator passes through the manipulator; causing the encoding circuit to generate the required control instructions. These control commands are electrical signals that are easily distinguishable from each other with certain characteristics, such as: a sine signal with the frequency of 270Hz is used as a command for controlling left turning, and a sine signal with the frequency of 350Hz is used as a command for controlling right turning, namely, sine signals with different frequencies represent different control commands. In addition to the available frequency characteristics, various instructions can be represented by amplitude and phase characteristics of sinusoidal signals, amplitude, width and phase characteristics of pulse signals, code group characteristics, and the like.
The command signal generated by the coding circuit is an electric signal with lower frequency and cannot be directly transmitted to a remote control target, and the command signal is also transmitted to the transmitting circuit so that the command signal is carried on a high-frequency signal (carrier wave) and can be transmitted by the transmitting antenna. Just as the goods are transported by a vehicle such as a train or an airplane, the command signal corresponds to the goods, and the carrier wave corresponds to the vehicle. The process by which the command signal is carried onto the carrier wave is called modulation, which is accomplished by the modulator of the transmitting circuit. The main function of the transmitting circuit is to generate carrier wave, and the modulator modulates the command signal on the carrier wave, and the modulated carrier wave is sent out through the antenna. The receiver is composed of a receiving circuit and a decoding circuit. The receiving circuit further includes a high frequency portion and a demodulator portion. Weak signals from the receiving antenna are selected and amplified by the high frequency part of the receiver and sent to the demodulator. Just as in the case of unloading cargo after arrival of a vehicle such as a train, aircraft, etc., the demodulator functions to "unload" the command signal from the carrier wave. Since the various command signals are mixed together, they are sent to the decoding circuit for decoding. The decoding circuit works like identifying and classifying the unloaded goods, and sends the goods to the using place respectively, and the decoding circuit labels various command signals and sends the command signals to the corresponding execution amplifying circuit. The execution amplifying circuit amplifies the instruction signal to have certain power for driving the execution mechanism. The actuating mechanism converts electric energy into mechanical actions, such as rotation of a motor, suction of an electromagnet and the like, and drives a controlled adjusting mechanism (such as a control surface), so that the controlled target is controlled.
Wherein the throttle rocker is in a static state at 1500 mu s, in a forward state at 1500 mu s-2000 mu s and in a backward state at 1000 mu s-1500 mu s; the direction rocker is in a static/straight running state at 1500 mu s, in a left turning state at 1500 mu s-2000 mu s and in a right turning state at 1000 mu s-1500 mu s; electrical control 301 will implement DA conversion by processing, outputting the corresponding voltage value.
When the throttle rocker is in a forward state or a backward state, namely, outputting 1500 mu s-2000 mu s or 1000 mu s-1500 mu s, the first driving motor 201a and the second driving motor 202a of the steering throttle are driven to rotate in a differential mode, and differential steering is performed at the moment; when the throttle rocker is in the middle position, namely 1500 mu s is output, the first driving motor 201a and the second driving motor 202a of the toggle direction throttle can reversely rotate at the same speed, and in-situ steering is performed at the moment.
Since the first drive motor 201a and the second drive motor 202a are placed in opposite positions, the rotation speeds of the motors at both sides are opposite in a normal state, the first drive motor 201a is rotated forward, and the second drive motor 202a is rotated backward.
It should be noted that the engine 205 is ignited and extinguished as digital output control, and the engine throttle 205b is adjusted in size by analog output.
The mowing assembly 400 drives the driving assembly 200 to advance, retract, etc. at the place where mowing is required through the cutter drive shaft 402a and the belt clutch 401a of the engine output shaft 205a.
