Description

Technical Field

[0001] The present invention relates to an arm-type aerial work platform, and in particular to a remote control system and method for an aerial work platform with good motion coordination consistency and high working efficiency. Background Art

[0002] Aerial work platforms are a type of aerial work equipment used worldwide, primarily in construction and other locations. They offer numerous advantages, including flexibility, safety, and ease of operation. However, when operating in confined spaces or during the transportation and loading and unloading of containers and carts, these platforms and turntables face limitations due to factors such as the driving environment, limiting operator flexibility and posing safety risks. Furthermore, when coordinated actions such as lifting and lowering multiple devices simultaneously are required, manual operation is inconsistent, and the naked eye cannot accurately determine the difference in lifting height with other devices to adjust the movements accordingly. Consequently, multi-machine collaboration is ineffective, leaving significant room for improvement in efficiency and other aspects.

[0003] The current remote control methods for boom-type aerial work platforms are mostly used for the control of a single device during loading, unloading and transportation. They require a dedicated remote control and a dedicated receiving device installed on the aerial work platform to receive the remote control's transmission signal for remote control. They are mainly used for loading and unloading operations during the transportation of containers and flatbed trucks on boom-type aerial work platforms. The remote control systems used in the existing technology for boom-type aerial work platforms use a dedicated remote control as a transmitter to remotely control a single aerial work platform device, which cannot meet the control requirements of multiple devices working in coordination. In addition, such remote controls need to be further improved in terms of miniaturization and lightweighting, otherwise it will be difficult to meet the user's demand for flexible and portable terminal operating equipment. At the same time, the receiver, as a device for receiving signals, also requires additional installation space, and an installation location needs to be reserved in advance, otherwise it will be inconvenient to add remote control functions later.

[0004] With the widespread application of boom-type aerial work platforms, it is necessary to design a remote control system for aerial work platforms to improve manual operation errors and personnel safety, improve work efficiency, and enhance the consistency of collaborative work. Summary of the Invention

[0005] Purpose of the invention: The purpose of the present invention is to provide a remote control system and method for an aerial work platform with good motion coordination consistency and high work efficiency.

[0006] Technical solution: The aerial work platform remote control system described in the present invention includes a smart phone terminal, a relay module, a turntable controller and aerial work platform equipment. The smart phone terminal is used to download application software and perform remote login. A connection is established between the smart phone terminal APP and the relay modules installed on multiple aerial work platforms in the area through a local area network. The relay module processes the instructions sent by the mobile phone and converts them into bus signals and forwards them to the turntable controller. The turntable controller makes a judgment and outputs the received signals. The pumps and valve components installed on the aerial work platform equipment start working after receiving the output signals of the turntable controller, thereby realizing the boom lengthening and extension of multiple aerial work platform equipment.

[0007] Furthermore, the user enters the account number and password for identity verification during the remote login.

[0008] Furthermore, the relay module includes multiple GPS gateways.

[0009] Furthermore, the aerial work platform device is provided with multiple devices.

[0010] Furthermore, the turntable controller receives the bus signal, makes a judgment, and outputs a corresponding control signal, which is transmitted to the hydraulic motor solenoid valve through a hardware circuit.

[0011] Furthermore, the solenoid valve starts to operate after being energized, and the aerial work platform equipment starts to perform the boom luffing action.

[0012] Furthermore, the smart phone terminal includes a tablet and a laptop.

[0013] The remote control method for an aerial work platform according to the present invention comprises the following steps:

[0014] (1) Enter the password on the turntable control panel of the aerial work platform equipment to successfully activate the wireless module of the whole machine and turn on the Bluetooth or WiFi mode of the mobile phone;

[0015] (2) Log in to the control software on your mobile phone and enter the password for identity authentication to establish a connection with the aerial work platform equipment;

[0016] (3) After the connection is successful, enter the mobile phone APP control page, click the corresponding action name entry, and the action command will be sent to the GPS gateway via the mobile phone Bluetooth or WiFi;

[0017] (4) The GPS gateway processes the received signal and forwards it to the turntable controller. The turntable controller makes a judgment after receiving the signal and outputs it through the output module. The components that receive the signal start to move, thereby realizing the corresponding movement of the entire boom platform.

[0018] Furthermore, the GPS gateway in step (3) is used as a signal receiving device by means of the local Bluetooth and wireless network provided by the GPS.

[0019] Furthermore, the output module of step (4) includes control plugs of various action pumps and valve components of the aerial work platform.

[0020] Beneficial effects: Compared with the existing technology, the present invention has the following significant advantages: by coordinating the control of multiple aerial work platform equipment, the consistency of equipment movements and work efficiency can be improved, manpower can be liberated, and safety can be improved; the remote control system uses a smart phone as an operating terminal device to replace the traditional remote control, which is flexible and lightweight; the gateway is integrated with the GPS, and the local Bluetooth and wireless network of the GPS are used as signal receiving devices, which significantly improves the system's after-installation portability and effectively reduces costs.

[0025] Users can download the application software on the smartphone terminal 1 and log in remotely. When logging in, they need to enter their account and password for identity authentication. At the same time, a connection is established between the smartphone APP and the GPS gateway installed on multiple aerial work platforms in the area through Bluetooth or WiFi local area network. The GPS gateway receives the command sent by the mobile phone, processes it, converts it into a bus signal, and forwards it to the turntable controller 3. After receiving the signal, the turntable controller 3 makes a judgment and outputs it. The various pumps and valve components installed on the aerial work platform equipment 4 start working after receiving the output signal of the turntable controller 3, thereby realizing the boom luffing, extension and retraction of multiple aerial work platform equipment. For example, after a staff member logs in to the mobile terminal APP and successfully connects to the equipment, he enters the mobile terminal APP control page and clicks on the boom luffing entry, which is to issue a luffing command, which is forwarded by the GPS gateway to the turntable controller. After receiving it, the turntable controller makes a judgment and outputs the corresponding control signal, which is transmitted to the hydraulic motor solenoid valve through the hardware circuit. The solenoid valve starts to operate after receiving the power, and the aerial work platform begins to perform the boom luffing action.

[0026] like Figure 2 As shown, the remote control method of the aerial work platform of the present invention includes the following steps:

[0027] (1) Enter the password on the turntable control panel of the aerial work platform equipment to successfully activate the wireless module of the whole machine and turn on the Bluetooth or WiFi mode of the mobile phone;

[0028] (2) Log in to the control software on your mobile phone and enter the password for identity authentication to establish a connection with the aerial work platform equipment;

[0029] (3) After the connection is successful, enter the mobile phone APP control page, click the corresponding action name entry, and the action command will be sent to the GPS gateway via the mobile phone Bluetooth or WiFi;

[0030] (4) The GPS gateway processes the received signal and forwards it to the turntable controller. The turntable controller makes a judgment after receiving the signal and outputs it through the output module. The components that receive the signal start to move, thereby realizing the corresponding movement of the entire boom platform.

[0031] The input signal is a mobile phone APP; the relay module is a GPS gateway; the control module is a turntable controller; and the output module is the control plug of various action pumps, valves and other components of the aerial work platform.
