Description

Technical Field

[0001] This utility model relates to the field of marine electrical and control technology, specifically to a tugboat external fire-fighting control system with optimized hardware structure. Background Technology

[0002] Tugs play a vital role in firefighting and rescue operations in ports and at sea. Their external firefighting control systems are the core equipment for accomplishing these tasks. However, existing tugboat external firefighting control systems often suffer from poor stability and high failure rates due to aging or discontinued hardware such as control panels.

[0003] Specifically, early-used dedicated control panels (such as a certain Siemens series) have been discontinued for many years, making spare parts difficult to obtain. Furthermore, their dedicated configuration software is encrypted, making maintenance and modification extremely difficult and prone to problems such as system crashes. Existing PLCs (such as Siemens S7-1200) may have issues such as abnormal program termination and poor compatibility with new and old peripherals. In fire-fighting mode, the main unit may experience overload and speed reduction due to imperfect load control logic, affecting fire-fighting effectiveness. Due to limitations in core control hardware, the reliability and maintainability of the entire system are reduced, severely impacting the tugboat's fire emergency response capabilities. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a tugboat external fire-fighting control system with optimized hardware structure, comprising: a control panel module, a PLC control module, a remote operation module, and an actuator. The control panel module is communicatively connected to the PLC control module, and the PLC control module is connected to both the remote operation module and the actuator. The control panel module is a general-purpose industrial control computer running on a Windows operating system and configuration software, and the PLC control module is a programmable logic controller.

[0005] Furthermore, the model of the general-purpose industrial control computer is Advantech PPC-3150.

[0006] Furthermore, the programmable logic controller is a Siemens S7-200 smart series PLC.

[0007] Furthermore, the control panel module is connected to the PLC control module via an Ethernet interface or an RS485 interface.

[0008] Furthermore, the external mounting dimensions of the Advantech PPC-3150 industrial computer are consistent with the mounting dimensions of the original Siemens control panel.

[0009] Furthermore, the PLC control module is connected to the actuator via a hardwired connection to control the pitch and rotation of the fire monitor, the opening and closing of the valve, and the start and stop of the fire pump.

[0010] Furthermore, the remote operation module is a handheld remote controller, which is connected to the PLC control module via a wireless communication module.

[0011] Furthermore, the wireless communication module is a 2.4G wireless module or a radio communication module.

[0012] Furthermore, the PLC control module contains an optimized control program configured to monitor and limit the load of the ship's main engine in fire-fighting mode.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By adopting Advantech industrial PCs and Siemens S7-200smart PLCs, which are widely available and versatile, the spare parts shortage caused by the original equipment's discontinuation was fundamentally resolved. The system operates more stably and reliably. The new industrial PCs have the same external dimensions as the original control panel, enabling in-situ replacement, simplifying the installation process, and reducing the difficulty and cost of modification. The universal hardware and open configuration software make subsequent maintenance, program modification, and component replacement simple and quick, reducing maintenance costs. By writing optimized control programs into the new PLCs, the load on the main unit is effectively monitored and limited, avoiding speed reduction problems caused by main unit overload during firefighting operations and ensuring the continuous and efficient operation of the fire protection system. The original ship's stable and reliable wireless remote control was retained, and a new operating interface was created to suit the crew's operating habits in conjunction with the new industrial PCs, ensuring ease of operation.

[0014] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings: Figure 1 This is a structural block diagram of the tugboat external fire-fighting control system described in this utility model. Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] like Figure 1As shown, the tugboat external fire-fighting control system with optimized hardware structure in this embodiment includes: a control panel module, a PLC control module, a remote operation module, and an actuator. The control panel module is communicatively connected to the PLC control module, and the PLC control module is connected to both the remote operation module and the actuator. The control panel module is a general-purpose industrial control computer running on a Windows operating system and configuration software, and the PLC control module is a programmable logic controller.

[0017] The model of the general-purpose industrial control computer is Advantech PPC-3150. As a mature general-purpose industrial control computer, the Advantech PPC-3150 has been tested by the market in terms of hardware stability and software support, providing a reliable hardware foundation for this system.

[0018] The programmable logic controller is a Siemens S7-200 smart series PLC. This series of PLCs has stronger processing capabilities and richer communication interfaces, providing hardware support for complex fire protection logic control and future function expansion.

[0019] The control panel module communicates with the PLC control module via an Ethernet interface or an RS485 interface. The use of an Ethernet interface ensures the real-time and high-speed data exchange between the human-machine interface and the controller, resulting in more timely operation response.

[0020] The Advantech PPC-3150 industrial PC has the same external installation dimensions as the original Siemens control panel on the ship. Hardware upgrades do not require any structural modifications to the ship's control console, simplifying the installation process and saving modification time and costs.

[0021] The PLC control module is connected to the actuator via hard-wired connection to control the pitch and rotation of the fire monitor, the opening and closing of valves, and the start and stop of the fire pump. Hard-wired connection (such as direct drive of I / O points) has strong anti-interference ability and stable signal transmission, ensuring direct control and the highest reliability for critical safety equipment such as fire monitors, valves, and pumps.

[0022] The remote operation module is a handheld remote controller that connects to the PLC control module via a wireless communication module. This allows the fire protection system to be controlled from outside the cockpit (such as from the deck, bow, or other optimal observation positions), enabling operators to flexibly choose their positions based on the fire situation and improve firefighting efficiency.

[0023] The wireless communication module is a 2.4G wireless module or a radio communication module. 2.4G communication is low-cost and high-speed; radio communication has strong diffraction capability and long transmission distance.

[0024] The PLC control module contains an optimized control program configured to monitor and limit the load of the ship's main engine in firefighting mode, ensuring the continuous and stable output of the main engine during firefighting operations and guaranteeing the continuity of firefighting work.

[0025] The working principle of this utility model is as follows: By adopting a general-purpose industrial control computer and a new type of PLC to build the core control architecture, the PLC serves as the processing center to receive local screen control and remote wireless commands. After internal optimization program analysis and load monitoring, the fire monitor, valves and fire pumps are reliably driven by hard wiring, forming a closed-loop control system that integrates command input, intelligent processing, power execution and status feedback. This fundamentally solves the stability and reliability problems of the original system caused by hardware aging and load loss, and realizes efficient, stable and intelligent control of tugboats for external fire fighting operations.
