Description

Technical Field

[0001] The utility model relates to the technical field of electric hoists, in particular to an intelligent wireless remote controller for controlling a DC electric hoist. Background Art

[0002] Electric hoists can be divided into DC electric hoists and AC electric hoists. They are a type of small lifting equipment with wide applications, widely used in production lines, assembly machines, and logistics conveyors in modern industries such as machinery manufacturing, automobiles, shipbuilding, and workpiece assembly. Due to its good portability and potential for intelligent upgrading, the DC electric hoist belongs to the new development trend in the lifting equipment industry and has a very broad application prospect. However, the control part of the current DC electric hoist basically still uses a wired control handle. During use, due to the limitations of the length and space of the wired control handle, the operator needs to be close to the DC electric hoist, unable to freely choose the best ideal operation position, and unable to avoid using it in places with poor visibility and dangerous operation locations, posing significant safety hazards. Although traditional AC electric hoists also use wireless remote control receivers, the receiving circuit main board uses discrete components, including at least two contactors, air switches, relays, and capacitors, which have unsafe factors such as large volume and use of strong electricity. After frequent use, it is easy to cause damage to its internal components and even burn out the machine. At the same time, there is no human-machine interaction interface, and the relevant parameters of the electric hoist cannot be observed in real time. Therefore, it is an urgent problem to develop an intelligent wireless remote controller with a small volume, convenient installation, and good safety performance. Summary of the Invention

[0003] To overcome the above problems existing in the prior art, the purpose of the utility model is to provide an intelligent wireless remote controller for controlling a DC electric hoist with a reasonable structural design, small volume, simple and convenient operation, safe and reliable use, and good human-machine interaction.

[0004] The technical solution adopted by the present utility model to solve the above technical problems includes a transmitting unit, a receiving unit and a driving unit. The transmitting unit includes a transmitting handle, on which a transmitting micro-control unit, a two-way wireless transmitting module, a transmitting power supply module, a buzzer, an LCD intelligent display screen, a start / reset button, an emergency stop button, an up / down button and a left / right button are correspondingly installed. The receiving unit includes a receiving micro-control unit, a two-way wireless receiving module and a receiving power supply module. The driving unit includes a driving controller and a DC electric hoist. The transmitting micro-control unit receives and processes the control signals of rising, falling, moving left or moving right sent by the transmitting handle, transmits through the two-way wireless transmitting module and receives through the two-way wireless receiving module, and then the receiving micro-control unit controls the driving controller to drive the DC electric hoist to rise, fall, move left or move right. The receiving micro-control unit receives and processes the working parameters and warning information of the driving controller and the DC electric hoist, transmits through the two-way wireless receiving module and receives through the two-way wireless transmitting module, and then the transmitting micro-control unit transmits them to the LCD intelligent display screen on the transmitting handle for display.

[0005] A further solution of the present utility model is that the transmitting power supply module provides power for the transmitting micro-control unit and the two-way wireless transmitting module, and is powered by 2 No. 5 batteries or a 9V battery. The receiving power supply module provides power for the receiving micro-control unit and the two-way wireless receiving module, and is powered by the working power supply on the driving controller.

[0006] A further solution of the present utility model is that the driving controller is installed on the control box of the DC electric hoist, and a socket is provided on the driving controller. The receiving unit is installed on the socket of the driving controller in a plug-in manner.

[0007] A further solution of the present utility model is that an NFC module for controlling the operation of the transmitting handle and an NFC key paired with the unique serial number of the NFC module are installed on the transmitting handle. When the user approaches the paired NFC key to the NFC module, the transmitting micro-control unit controls the buzzer to emit a beeping sound to unlock, and the start / reset button, up / down button and left / right button on the transmitting handle can be used to control the operation of the DC electric hoist. When the user does not press the start / reset button, up / down button and left / right button for a period of time, the transmitting micro-control unit controls the buzzer to emit a beeping sound to automatically lock, and the user needs to unlock with the NFC key again to use it.

[0008] A further solution of the present utility model is that the working parameters of the driving controller and the DC electric hoist include working mode, working current and voltage, lifting speed and load weight parameters, and the warning information includes under-voltage, over-current, over-temperature and overload information.

[0009] A further solution of the present utility model is that when the LCD intelligent display screen is powered on, the battery voltage and power of the transmitting power supply module are displayed.

[0010] A further solution of the present utility model is that the start reset button is used to control the wireless connection between the two-way wireless transmission module and the two-way wireless reception module; when the start reset button is turned on or off, the two-way wireless transmission module and the two-way wireless reception module are wirelessly connected or disconnected, and the start reset information is displayed on the LCD intelligent display screen.

[0011] A further solution of the present utility model is that the emergency stop button controls the drive controller through the transmitting unit and the receiving unit, and then the drive controller controls the DC electric hoist to stop.

[0012] After adopting the above structure, compared with the prior art, there are the following advantages and effects: First, the intelligent wireless remote control is used to control the up and down lifting, left and right walking, and start reset of the DC electric hoist. The operator can freely choose the best operation position, avoid poor visibility and dangerous operation locations, liberate personal freedom, ensure personal safety, is simple and convenient to operate, has good running continuity, high work efficiency, and low labor intensity. Second, the human-machine interaction interface is added, and the working parameters and warning information during operation are fed back to the LCD intelligent display screen. The operator can timely understand the working state of the equipment and the faults that occur, and timely solve various problems that occur during use, making the control process more intelligent, safe, comprehensive, and intuitive. Third, the unique single serial number and the matching NFC key are adopted, which can track the dynamic information such as the production, sales, and use of the product, is conducive to the manufacturer's product quality management, and can prevent safety accidents caused by incorrect operation of the equipment. Fourth, the power supply adopts weak current control, and the operation is safer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0016] Figure 1 and Figure 2As shown in the figure, this is a specific implementation of an intelligent wireless remote control for a DC electric hoist of the present utility model. It includes a transmitting unit 1, a receiving unit 2, and a driving unit 3. The transmitting unit 1 includes a transmitting handle 13, on which a transmitting microcontroller unit, a two-way wireless transmitting module, a transmitting power supply module, a buzzer, an LCD intelligent display screen 6, a start / reset button 4, an emergency stop button 5, up / down buttons 7, 8, left / right buttons 9, 10 are correspondingly installed; the receiving unit 2 includes a receiving microcontroller unit, a two-way wireless receiving module, and a receiving power supply module; the driving unit 3 includes a driving controller and a DC electric hoist. The transmitting power supply module provides power for the transmitting microcontroller unit and the two-way wireless transmitting module, and is powered by 2 AA batteries or a 9V battery; the receiving power supply module provides power for the receiving microcontroller unit and the two-way wireless receiving module, and is powered by the working power supply on the driving controller. The driving controller is installed on the control box of the DC electric hoist, and a socket is provided on the driving controller. The receiving unit 2 is installed on the socket of the driving controller in a plug-in manner. The transmitting microcontroller unit receives and processes the control signals of rising, falling, moving left or moving right sent by the transmitting handle 13, through the transmission of the two-way wireless transmitting module and the reception of the two-way wireless receiving module, and then the receiving microcontroller unit controls the driving controller to drive the DC electric hoist to rise, fall, move left or move right.

[0017] In order to achieve human-computer interaction, display working parameters and warning information, and timely understand the working status of the equipment and the faults that occur, the receiving microcontroller unit receives and processes the working parameters and warning information of the driving controller and the DC electric hoist. The working parameters of the driving controller and the DC electric hoist include working mode, working current and voltage, lifting speed, and load weight parameters. The warning information includes under-voltage, over-current, over-temperature, and overload information. Through the transmission of the two-way wireless receiving module and the reception of the two-way wireless transmitting module, and then transmitted by the transmitting microcontroller unit to the LCD intelligent display screen 6 on the transmitting handle for display. When warning information is displayed, the buzzer emits a beeping sound to ensure that the operator can timely solve various problems that occur during use.

[0018] To prevent misoperation and facilitate device management, an NFC module 11 for controlling the operation of the transmitting handle 13 and an NFC key 12 paired with the unique serial number of the NFC module 11 are installed on the transmitting handle 13; when the user brings the paired NFC key 12 close to the NFC module 11, the transmitting micro-control unit controls the buzzer to emit three beeping sounds, indicating that it has been unlocked. At this time, the start / reset button 4, up / down buttons 7, 8, left / right buttons 9, 10 on the transmitting handle 13 can be used to control the operation of the DC electric hoist; when the user does not press the start / reset button 4, up / down buttons 7, 8, left / right buttons 9, 10 for a period of time, such as 15 minutes, the transmitting micro-control unit controls the buzzer to emit three beeping sounds to automatically lock, and the user needs to use the NFC key 12 to unlock it again.

[0019] To prevent being unable to control due to too low battery power, the LCD intelligent display screen 6 displays the battery voltage and power of the transmitting power supply module when it is powered on. When the power is too low, the buzzer of the LCD intelligent display screen 6 emits a display and beeping sound in time.

[0020] To achieve the normal power-on function, the start / reset button 4 is used to control the wireless connection between the two-way wireless transmitting module and the two-way wireless receiving module; when the start / reset button 4 is turned on or off, the two-way wireless transmitting module and the two-way wireless receiving module are wirelessly connected or disconnected, and the start / reset information is displayed on the LCD intelligent display screen 6. Press the start / reset button 4 once, and the two-way wireless transmitting module and the two-way wireless receiving module establish a wireless connection. Press it again, and the two-way wireless transmitting module and the two-way wireless receiving module are disconnected, and the connection status is displayed on the LCD intelligent display screen 6.

[0021] To ensure safe use, the emergency stop button 5 controls the drive controller through the transmitting unit 1 and the receiving unit 2, and then the drive controller controls the DC electric hoist to stop. In any case, when the emergency stop button 5 is pressed, the transmitting micro-control unit wirelessly transmits through the two-way wireless transmitting module and the two-way wireless receiving module to control the receiving micro-control unit. The receiving micro-control unit controls the drive controller to cut off the power supply of the DC electric hoist to achieve shutdown, and then cuts off the power supply of the transmitting power supply module. When the emergency stop button 5 is turned on, the transmitting power supply module is powered on, and the wireless transmission between the two-way wireless transmitting module and the two-way wireless receiving module is in a disconnected state, and this state is displayed on the LCD intelligent display screen 6.

[0022] In addition to being used as an intelligent wireless remote control for controlling DC electric hoists, the utility model can also be widely applied to DC electromechanical products with the same control method.

[0023] The above are only specific embodiments of the present utility model, and do not impose any formal restrictions on the present utility model. Without departing from the technical solution of the present utility model, simple modifications, equivalent changes or modifications made all fall within the protection scope of the present utility model.
