Description

Technical Field

[0001] The present application belongs to the field of remote control technology, and specifically relates to a tower crane remote control device and a tower crane remote control system. Background Art

[0002] Tower crane is a rotating crane with a boom mounted on the top of a tall tower. It has a large operating space and is mainly used for vertical and horizontal transportation of materials and installation of building components in housing construction. With the increasing use of tower cranes in construction projects, operators are increasingly demanding convenience in tower crane commissioning and control operations.

[0003] Existing tower crane commissioning and control work is mostly performed by operators in the tower crane or the driver's cab. This operation requires operators to climb up the tower crane to complete the operation, which has safety risks and may threaten the personal safety of operators. In some traditional methods, short-range wireless remote control technology can be used to control the tower crane for hoisting through a remote control on the ground. However, the control distance of this method is limited and is restricted to the vicinity of the tower crane, making it impossible to control the tower crane remotely. Especially for some scenarios that need to demonstrate tower crane control, such as product demonstration activities conducted by marketing personnel, since remote demonstrations cannot be achieved, on-site control must be carried out, which makes this demonstration method inconvenient and the demonstration scenario has great limitations.

[0040] Figure 1 The tower crane remote control device 10 of the first embodiment of the present application is schematically shown. As Figure 1 shown, in an embodiment of the present application, a tower crane remote control device 10 is provided, and the tower crane remote control device 10 includes:

[0041] A wireless remote control transmitter 100;

[0042] A wireless remote control receiver 200, wirelessly connected to the wireless remote control transmitter 100, and used to receive the control signal sent by the wireless remote control transmitter 100;

[0043] A first router 300, connected to the tower crane remotely controlled device through the Internet;

[0044] CAN (Controller Area Network) - Ethernet signal converter 400. The wireless remote control receiver 200 is connected to the first router 300 through the CAN - Ethernet signal converter 400. The CAN - Ethernet signal converter 400 is used to receive the control signal sent by the wireless remote control receiver 200, and after signal conversion of the control signal, it is sent to the first router 300;

[0045] The first router 300 is used to send the control signal after signal conversion to the tower crane remote controlled device 20.

[0046] In this embodiment, it should be noted that the tower crane remote control device 10 is used to realize the remote control of the tower crane, which can make the control of the tower crane not limited to a short distance. Specifically, the tower crane remote control device 10 includes a wireless remote control transmitter 100, a wireless remote control receiver 200, a first router 300, and a CAN - Ethernet signal converter 400. Among them, the wireless remote control transmitter 100 is used to receive the control signal input by the operator and send the control signal to the wireless remote control receiver 200. Wireless communication is a communication method that uses the characteristic that electromagnetic wave signals can propagate in free space for information exchange. In wireless communication, electromagnetic waves are the medium for signal transmission. The electromagnetic waves are emitted into the air through the antenna, and then received by the antenna at the receiving end and demodulated to restore the original information. In this embodiment, wireless communication is used for signal transmission between the wireless remote control transmitter 100 and the wireless remote control receiver 200.

[0047] It should be noted that the first router 300 refers to the router in the tower crane remote control device 10 used for Internet communication. The Internet mainly uses the packet - switching communication method. Packet - switching is a communication method that divides data into packets of a certain length and transmits them in the network in a "store - and - forward" manner. The Internet realizes packet - switching communication on a global scale through the TCP / IP protocol family. The tower crane remote controlled device is set on the tower crane and is used to receive the control signal sent by the tower crane remote control device 10 to control the operation of the tower crane based on this control signal. In this embodiment, Internet communication between the tower crane remote control device 10 and the tower crane remote controlled device is realized through the first router 300, and thus the remote control of the tower crane is realized.

[0048] It should be noted that after the wireless remote control receiver 200 receives the control signal sent by the wireless remote control transmitter 100, it further transmits the control signal via the CAN bus. To achieve remote control of the tower crane, the control signal output based on the CAN bus needs to be further forwarded to the tower crane remote controlled device at the tower crane end via the first router 300. Since the CAN bus is a serial communication protocol based on message broadcasting, mainly used for short-distance and high-reliability data communication between devices; Ethernet is a widely used network protocol that supports long-distance and high-rate data transmission. In this embodiment, the signal conversion between the wireless remote control receiver 200 and the first router 300 is achieved through the CAN-Ethernet signal converter 400, so as to convert the control signal output by the wireless remote control receiver 200 based on the CAN bus into a control signal in Ethernet form and input it to the first router 300, so that the first router 300 sends the control signal to the tower crane remote controlled device at the tower crane end to achieve remote control of the tower crane.

[0049] Specifically, in one embodiment, the CAN-Ethernet signal converter 400 is connected to the wireless remote control receiver 200 via the CAN bus, and the CAN-Ethernet signal converter 400 is connected to the first router 300 via a network cable.

[0050] It should be noted that the CAN-Ethernet signal converter 400 can receive data from the CAN bus and convert it into an Ethernet format data packet. In this embodiment, the control signal output based on the CAN bus sent by the wireless remote control receiver 200 is obtained through the CAN bus, and the control signal is signal-converted to generate a control signal in Ethernet form and output it to the first router 300 via a network cable.

[0051] In this embodiment, the tower crane remote control device 10 includes a wireless remote control transmitter 100, a wireless remote control receiver 200, a first router 300, and a CAN-Ethernet signal converter 400.

By realizing long-distance control of the tower crane, the scene limitation of the tower crane control demonstration is reduced, and at the same time, the convenience of the tower crane control demonstration is improved.

[0052] Specifically, in one embodiment, the wireless remote control transmitter 100 includes a rocker for generating a control signal based on a user operation.

[0053] In this embodiment, it should be noted that the wireless remote control transmitter 100 can be used to receive a user operation and generate a corresponding control signal based on the user operation.

The wireless signal generator generates a corresponding control signal based on the control instruction. In one embodiment, the wireless remote control transmitter 100 may further include components such as a display lamp and a key. Among them, the display lamp can be used to indicate the power-on state, operating state, and device connection state of the wireless remote control transmitter 100, etc. The key can be used for operations such as device reset, password input, and device start / stop control.
