Description

Technical Field

[0001] This utility model relates to the field of industrial crane control technology, and in particular to a crane control line optimization device based on a remote I / O module. Background Technology

[0002] In industrial production, overhead cranes are crucial material handling equipment, and the stability and reliability of their control systems directly impact production efficiency and operational safety. Traditionally, multiple sets of cables are used to connect the cab control console to the main control cabinet of an overhead crane to transmit various operational commands. However, this traditional connection method has significant drawbacks: firstly, the complex wiring not only increases installation costs and time, but also occupies more space due to the large number of cables; secondly, numerous cable interfaces are prone to poor contact and signal interference, increasing equipment failure rates and maintenance difficulty. With the development of industrial automation technology, higher demands are placed on the simplification, efficiency, and intelligence of overhead crane control systems, urgently requiring a technical solution that optimizes the connection between cab-operated commands and the remote control cabinet. Utility Model Content

[0003] The technical problem to be solved by this utility model is to solve the problems of complex wiring, high cost and high failure rate between the traditional cab control console and the main control cabinet. By adopting a remote IO module, the original complex wiring can be replaced by a single network cable, simplifying the connection structure and improving system stability and maintenance convenience.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A vehicle control route optimization device based on a remote I / O module includes: Remote control unit: including electrical box, which contains PLC for receiving and processing operation commands to realize the logic control of the vehicle; Remote control receiver unit: installed on the electrical box side, its output terminal is connected to the PLC, used to receive remote control operation commands and transmit them to the PLC; The cab control unit includes a cab control console and a remote I / O module added to the control console. The operation command output terminal of the cab control console is connected to the remote I / O module. The remote I / O module is connected to the PLC in the electrical box via a network cable for transmitting operation commands from the cab to the PLC. Switching Unit: This is a cab / remote control switch added to the cab. The cab / remote control switch is directly connected to the PLC via high and low level switching, and is used to switch between cab operation mode and remote control operation mode.

[0005] The beneficial effects of this utility model are as follows: 1. Simplified wiring structure: By setting up a remote IO module in the cab control panel, a single network cable replaces the traditional multiple complex cables, significantly reducing the number and complexity of wiring installations, and lowering installation costs and space requirements.

[0006] 2. Improve system stability: The number of line interfaces is reduced, which lowers the risk of failure due to poor contact, aging lines, etc. At the same time, the network cable transmission has stronger anti-interference ability, ensuring the stable transmission of operation commands.

[0007] 3. Enhanced maintenance convenience: The simplified circuit structure makes troubleshooting more efficient. Staff do not need to deal with complicated circuits and can quickly locate problems through the communication status of the remote IO module, thus shortening maintenance time.

[0008] 4. Flexible switching: The cab / remote control switch allows for convenient switching of operating modes from inside the cab, meeting the needs of different work scenarios and improving operational flexibility. Attached Figure Description

[0010] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0011] Please refer to Figure 1 The specific embodiment of this utility model relates to a vehicle control route optimization device based on a remote I / O module 21, comprising: Remote control unit: including electrical box 1 added next to the electrical control cabinet of the trolley walkway, and PLC 11 installed in electrical box 1 to receive and process operation commands and realize the logic control of the trolley. Remote control receiver unit: installed on the electrical box 1 side, its output terminal is connected to PLC11, used to receive remote control operation commands and transmit them to PLC11; The cab control unit includes a cab control console 2 and a remote I / O module 21 added to the control console. The operation command output terminal of the cab control console 2 is connected to the remote I / O module 21. The remote I / O module 21 is connected to the PLC 11 in the electrical box 1 via a network cable 3 for transmitting operation commands from the cab to the PLC 11. Switching unit: The cab / remote control switch 22 is added to the cab. The cab / remote control switch 22 is directly connected to the PLC11 through high and low level switching, and is used to switch between cab operation mode and remote control operation mode.

[0012] The above-mentioned improvement description of the vehicle control route optimization device based on remote IO module 21: 1. Hardware Deployment: A new electrical box 1 is added next to the electrical control cabinet of the trolley walkway, with a built-in series PLC 11; a remote IO module 21 is added in the cab control console 2, and the original wiring of the cab control console 2 is connected to the remote IO module 21; a remote control receiver is installed on the side of the electrical box 1, and its output is connected to the PLC 11; a cab / remote control switch 22 is installed in the cab, and the switch output is directly connected to the PLC 11.

[0013] 2. Optimize the wiring connection: Disconnect the original complex wiring connection between the cab control console 2 and the electrical control cabinet, and establish a communication connection between the remote IO module 21 in the cab control console 2 and the PLC11 in the electrical box 1 through a network cable 3.

[0014] 3. Command transmission and control: When the switch is in the cab operation mode, the operation commands of the cab control console 2 are transmitted to the PLC11 via the remote IO module 21 and the network cable 3. The PLC11 controls the driving action according to the command. When the switch is in the remote control operation mode, the remote control receiver receives the remote control command and transmits it to the PLC11. The PLC11 controls the driving action according to the remote control command.

[0015] In the above embodiments, during the modification of a five-speed main and auxiliary hook gantry crane in a factory, the technical solution of this utility model was used to optimize the control circuit: 1. Install a new electrical box 1AN next to the A0 cabinet of the trolley walkway electrical control cabinet, and configure Huichuan EASY series PLC11 as the logic control core inside; 2. Integrate a remote I / O module 21 inside the control panel in the driver's cab, and reconnect the various operation buttons, indicator lights and other wiring on the control panel to the remote I / O module 21; 3. Remove the original multiple control cables between the cab control console 2 and the electrical box 1A0, and connect the remote IO module 21 to the PLC11 in the AN cabinet through an industrial Ethernet cable 3 to establish a data communication link; 4. Install a remote control receiver on the side of the electrical box 1AN, and connect its signal output terminal to the signal input terminal of PLC 11; 5. Install the cab / remote control switch 22 in a suitable location in the cab. Connect the two output pins of the switch to the corresponding input interface of PLC11 through wires. The mode switching control is achieved by changing the high and low levels.

[0016] After the modification is completed, when the driver switches the switch to the "cab" position, the switch sends a high-level signal to the PLC11, and the PLC11 switches to the cab operation mode. The driver's operation commands on the cab control panel 2 are processed by the remote IO module 21 and transmitted to the PLC11 in real time via the network cable 3. The PLC11 controls the trolley movement, main and auxiliary hook lifting and lowering, and other actions of the trolley according to the commands. When the switch is switched to the "remote control" position, the switch sends a low-level signal, and the PLC11 switches to remote control mode. The commands issued by the operator through the remote control are received by the remote control receiver and transmitted to the PLC11 to realize remote control.

[0017] Actual operation has verified that the wiring layout of the crane control system is simple and clear, the failure rate is reduced by more than 60% compared with that before the modification, and the time for maintenance personnel to troubleshoot wiring problems is reduced by 70%, which significantly improves the operational stability and production efficiency of the crane.
