[0021] The present invention is further described in detail below through the accompanying drawings and specific implementation methods.

[0022] like Figure 1 As shown, an embodiment of the utility model provides a wireless remote control device for a shovel, wherein the wireless remote control device communicates with a wireless receiver, and the wireless receiver is arranged on the shovel, and the wireless remote control device includes a shell 1 and a control panel; a control circuit is arranged inside the shell 1, and the control circuit includes a microprocessor, a power supply, a communication module and a drive module; the control panel includes a display screen 2, a plurality of dip switches 3 and a plurality of control buttons 4; each of the control buttons is respectively connected to a drive module, the drive module is connected to a microprocessor, and the microprocessor is connected to a communication module; the microprocessor, the communication module, the drive module and the display screen 2 are respectively connected to a power supply.

[0023] As shown in FIG. 1 , the plurality of dip switches 3 include a power switch and a plurality of standby switches. The power switch is connected to the power supply in the box. When the power switch is turned on, the power supply is supplied as a whole. The power supply can be a rechargeable lithium battery.

[0024] The microprocessor adopts STM32 series chips, and specifically the main control chip can be STM32F103ZET6, and the microprocessor is connected to an AD acquisition module. The AD acquisition module adopts a chip model of AD7705.

[0025] like Figure 2 As shown, the driving module is composed of a plurality of adjustable resistors, and the adjustable control end of each adjustable resistor is connected to a control button, and the other end is connected to the AD acquisition module. Figure 2 As shown in , each control button is connected to the potentiometer SW during wiring. Multiple control buttons can control the telescopic cylinder horizontal movement, mechanical arm rotation, boom lifting, boom telescopic, arm lifting, bucket lifting, bucket opening and closing, etc. The potentiometer SW is connected to 7 variable resistors (P1-P7). When the staff operates the control button, the variable resistor connected to the control button changes its resistance value, and the output voltage also changes accordingly. At this time, the transistor Q1 and operational amplifier U1 connected to each variable resistor are amplified, and then the signal is collected by AD7705. The collected signal is processed by the microprocessor STM32F103ZET6 and sent to the communication module and display screen. The control action being implemented is displayed on the display screen, such as: the telescopic cylinder moves 20% to the left.

[0026] The communication module adopts a 433MHZ wireless transmission module, and the model of the 433MHZ wireless transmission module is XL4456. It should be noted that the same 433MHZ wireless communication protocol is also adopted at the receiver end, specifically, XL520 is adopted as the receiving chip. The same microprocessor is set at the receiver end. After receiving the information using the 433MHZ antenna, the microprocessor is used to process it and then sends the control command to the shovel controller. The shovel controller controls the corresponding electromagnetic regulating valve. The electromagnetic regulating valve can control the hydraulic cylinders of various parts of the shovel, such as the telescopic cylinder, the big arm, and the small arm. When the shovel controller outputs different degrees of current or pulse signals, the electromagnetic regulating valve is controlled to move at different openings, so as to achieve the purpose of controlling the hydraulic cylinder to move according to the opening of the control command.
