Description

Technical Field

[0001] The present invention relates to the technical field of ship methanol gas leakage detection, and in particular to a multi-level monitoring methanol leakage point judgment and emergency response system and a use method thereof. Background Art

[0002] The widespread use of methanol as a marine fuel, a volatile, toxic, and explosive gas, poses significant potential risks to the environment and personnel. Failure to promptly detect and address a methanol leak can not only cause serious health hazards but also potentially lead to major safety incidents such as fires and explosions. Therefore, detecting and responding to methanol leaks on board vessels has become a key challenge in the manufacture of methanol-fueled ships.

[0003] Currently, monitoring methanol gas leaks on ships primarily relies on traditional sensor technologies, such as fixed gas detectors and handheld detection devices. These devices typically rely on manual inspections and periodic monitoring, resulting in limited detection range and slow response times. In practice, gas leaks often occur in hidden areas or dynamically changing environments, making comprehensive, real-time monitoring difficult with traditional equipment. Furthermore, existing emergency response systems rely heavily on manual intervention and lack effective automated emergency response mechanisms, hindering timely repairs and risk control.

[0004] Therefore, it is necessary to provide a multi-level monitoring methanol leak point judgment and emergency system and its use method to solve the above technical problems. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies in the existing technology and provide a multi-level monitoring methanol leak point judgment and emergency response system and its use method. Through multi-level monitoring and intelligent control means, rapid detection of methanol gas leaks, leak point judgment and immediate repair are achieved.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A multi-level monitoring methanol leak point judgment and emergency response system includes a methanol gas detection system, an infrared temperature sensing system, an energy and control center, an emergency response system, and a terminal. The methanol gas detection system includes multiple methanol gas detectors arranged around a methanol storage tank, and the infrared temperature sensing system includes multiple infrared temperature sensors arranged around the methanol storage tank, with one methanol gas detector corresponding to one infrared temperature sensor. The emergency response system is a wall-climbing operation robot, which includes a main platform structure on which are mounted a first communication module, an ultrasonic flaw detection module, a single-chip microcomputer, an adhesive repair module, a positioning module, an alarm module, and a path planning and autonomous cruise module. The energy and control center includes a battery, a second communication module, a processor, and a controller. The energy and control center is electrically connected to the methanol gas detection system and the infrared temperature sensing system, respectively. The battery provides power to the methanol gas detection system and the infrared temperature sensing system. The controller is connected to the methanol gas detection system and the infrared temperature sensing system by wired communication. The processor preprocesses information transmitted by the second communication module. The second communication module is in wireless communication communication with the first communication module, and the first communication module is in wireless communication communication with the terminal.

[0008] Preferably, the ultrasonic flaw detection module of the wall-climbing robot is arranged at the bottom of the main platform structure, which is used to detect detailed information at the leakage point of the methanol storage tank. The single-chip microcomputer is used to process the information transmitted by the first communication module and the operation information of the wall-climbing robot. The adhesive repair module includes an adhesive storage tank arranged on the top surface of the main platform structure. A jet pump is provided inside the adhesive storage tank. The injection head of the jet pump passes through the adhesive storage tank and the main platform structure in sequence and extends to the bottom of the main platform structure. The positioning module, alarm module and path planning and autonomous cruise module are all arranged inside the main platform structure.

[0009] A method for using a multi-level monitoring methanol leak point judgment and emergency response system includes the following steps:

[0010] Step 1. The methanol gas detection system monitors the methane gas concentration around the methane storage tank in real time; Step 2. When the methanol gas detector in the methanol gas detection system detects that the methanol gas concentration within its sensing range exceeds the set concentration threshold, the information is fed back to the controller, and the controller sends a start command to the infrared temperature sensor corresponding to the methanol gas detector. The infrared temperature sensor runs and obtains the location information of the methanol storage tank leakage point according to the temperature difference; Step 3. The processor pre-processes the obtained location information of the methanol storage tank leakage point and transmits it to the first communication module through the second communication module. The first communication module sends the location information of the methanol storage tank leakage point to the single-chip microcomputer, and at the same time, the positioning module sends the location information of the wall-climbing operation robot itself to the single-chip microcomputer. The single-chip microcomputer sends the location information of the methanol storage tank leakage point and the location information of the wall-climbing operation robot itself to the path planning and autonomous cruise module. The path planning and autonomous cruise module performs path planning, and the single-chip microcomputer controls the wall-climbing operation robot to move to the methanol storage tank leakage point according to the planned path;

[0011] Step 4: The ultrasonic flaw detection module of the wall-climbing robot begins further detection of the leak point of the methanol storage tank, and controls the adhesive repair module to temporarily repair the leak point of the methanol storage tank based on the leak point size information fed back by the detection;

[0012] Step 5: The wall-climbing robot transmits the information of the methanol tank leakage point to the terminal through the first communication module to notify the staff. At the same time, the alarm module of the wall-climbing robot starts the alarm bell and flashing lights to provide guidance and prompts to the staff.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. The present invention integrates mature methanol gas detection technology, and uses the temperature difference between the methanol gas leakage point and the ambient temperature in combination with an infrared temperature sensing system to monitor methanol gas leakage in real time and independently determine the leakage point information.

[0015] 2. The present invention proposes a fully automatic methanol gas leakage monitoring, emergency maintenance and alarm system, which can quickly and effectively detect the spread of methanol gas, and perform emergency repairs and alarms, and can effectively avoid the risks of toxic and explosive methanol gas diffusion.
