[0002] Traditional AGV hand operators only have the function of moving AGVs, and do not have the ability to display and handle AGV problems. When problems occur during the operation of the AGV, the server is far away from the AGV or the working environment of the AGV is special, and it is not convenient to go to the server to view or handle the problem. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides an AGV hand operator control panel with a liquid crystal display applied to an AGV to solve the problems existing in the above-mentioned background technology.

[0004] The utility model provides the following technical solution: an AGV hand operator control panel with a liquid crystal display applied to an AGV, comprising an AGV hand operator with a liquid crystal display and a control panel, wherein the control panel is provided with a power module, an ADC acquisition module, a key matrix, an MCU module, a CAN bus module, and a liquid crystal display module.

[0005] Preferably, the AGV hand operator with LCD display has three main functions: first, controlling the movement of the AGV. By turning the button of the hand operator, the ADC acquisition circuit collects the information of the button and transmits it to the single-chip microcomputer. The single-chip microcomputer sends instructions to the motor driver through the CAN bus to control the movement of the AGV; second, controlling the online and offline of the AGV. When the single-chip microcomputer detects that a button with a specific function is pressed, it transmits the instruction to the wireless module through the serial port. The wireless module then transmits the instruction to the upper system through the AP, and the interface is called to complete the online and offline; third, LCD display. The upper system transmits the basic information of the AGV to the single-chip microcomputer through the AP and the wireless module, and then displays it through the LCD display module.

[0006] Preferably, the MCU used in the control board is a STM32F1 series single-chip microcomputer.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model provides an AGV hand operator with a liquid crystal display in conjunction with a control panel, and can view the cause of an AGV error through the basic AGV information displayed on the liquid crystal display, and can handle the problem by bringing the AGV online and offline through a key matrix, thereby reducing the difficulty and time consumed in handling AGV problems and reducing the safety issues caused by handling AGV problems.

[0014] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0015] The utility model provides an AGV hand operator control panel with a liquid crystal display for use in AGVs, such as Figure 1-4 As shown, it includes an AGV hand operator with a liquid crystal display and a control board, and the control board is provided with a power module 1, an ADC acquisition module 2, a key matrix 3, an MCU module 4, a CAN bus module 5, and a liquid crystal display module 6.

[0016] Furthermore, the AGV hand operator with LCD display has three main functions. First, control the movement of the AGV. By pressing the button of the hand operator, the ADC acquisition circuit collects the information of the button and transmits it to the single-chip microcomputer. The single-chip microcomputer sends instructions to the motor driver through the CAN bus to control the movement of the AGV. Second, control the AGV to go online and offline. When the single-chip microcomputer detects that a button with a specific function is pressed, it transmits the instruction to the wireless module through the serial port. The wireless module then transmits the instruction to the upper system through the AP, and the interface is called to complete the online and offline. Third, LCD display. The upper system transmits the basic information of the AGV to the single-chip microcomputer through the AP and the wireless module, and then displays it through the LCD display module.

[0017] Furthermore, the MCU used in the control board is a STM32F1 series microcontroller, which has an ARM Cortex-M3 core, 72MHz high-speed operation processing capability, 256KB of FLASH type program storage capacity, 48KB of total capacity RAM, 51 GPIO ports, and the STM32F1 microcontroller is responsible for the sending and receiving of all instructions.

[0018] The working principle of the utility model is as follows: when controlling the movement of AGV: the ADC acquisition circuit transmits the collected information to the MCU single-chip computer by collecting the input of the knob button. The MCU single-chip computer determines whether the AGV needs to move forward, backward, turn left or right, and transmits the instruction to the motor driver through the CAN bus; controlling the AGV to go online and offline: when the MCU single-chip computer detects that a button with a specific function is pressed, the instruction is transmitted to the wireless module through the serial port. The wireless module transmits the instruction to the upper system through the AP, and the interface is called to complete the online and offline; LCD display: the upper system transmits the basic information of the AGV to the single-chip computer through the AP and the wireless module, and then displays it through the LCD display module.
