Description

Technical Field

[0001] The present invention belongs to the technical field of ship design, and particularly relates to an intelligent sprinkler system for a vehicle cabin. Background Art

[0002] Nowadays, more and more ro-ro ships are transporting new energy vehicles, and the fire extinguishing system for new energy vehicles needs to be considered emphatically. The long-term high-temperature environment will cause lithium crystals to form at the negative electrode of the battery, which will eventually pierce the polymer diaphragm and lead to irreversible battery bulging. After getting out of control, it will become a fire. When the battery is thermally out of control, the positive electrode material will also react with the electrolyte and generate a large amount of heat and gas. The increased internal pressure of the battery will quickly eject low-flash-point electrolyte vapor and small-molecule combustible gases, resulting in the spontaneous combustion of new energy vehicles. The high temperature will quickly ignite other combustible materials inside the vehicle. When a local fire occurs in a lithium battery, it will spread rapidly within the lithium battery module in just a few seconds, igniting other adjacent lithium batteries, burning violently, with a fast diffusion speed and great difficulty in extinguishing the fire.

[0003] Traditional fire monitoring needs to meet the requirements of sufficient smoke concentration and temperature rising to the critical value before it can alarm, and it cannot meet the function of rapid fire extinguishing. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, the present invention provides an intelligent sprinkler system for a vehicle cabin, including a CCTV system with thermal imaging monitoring and a sprinkler system.

[0005] The CCTV system with thermal imaging monitoring includes a camera arranged inside the cabin. The camera is an infrared thermal imaging camera, and the camera is arranged directly above the garage deck. If the camera detects abnormal temperature, it will trigger the alarm of the CCTV system; when comprehensively analyzing and determining that the area needs to be extinguished, the CCTV system will transmit the result to the sprinkler system through a signal, and at the same time, close the ventilation system to isolate the air and automatically start the sprinkler system to extinguish the fire.

[0006] The sprinkler system includes a number of nozzles corresponding to each parking space position on the garage deck, and all the nozzles are connected to the ship's fire pipeline.

[0007] Furthermore, it further includes a pre-prevention system. The pre-prevention system includes a handheld thermal imaging device, and the temperature of the vehicle battery pack is checked by a handheld thermal imaging camera before the new energy vehicle is rolled onto the ship.

[0008] Furthermore, the pre-prevention system further includes a vehicle power inspection device to ensure that the remaining battery power of the electric vehicle does not exceed a preset value before uploading.

[0009] Further, it also includes an auxiliary configuration system, which includes a handheld foam fire extinguisher and a combustible gas detector. The vehicle deck loaded with lithium batteries is equipped with no less than two sets of handheld foam fire extinguishers and two sets of portable combustible gas detectors at the same time.

[0010] Further, the auxiliary configuration system also includes: identifying the area where new energy vehicles are loaded with eye-catching paint or signs, and configuring fresh water pipes in the open-air new energy loading area, and automatically starting water sprinkling and cooling under high-temperature climate conditions.

[0011] Further, it also includes a fire extinguishing reminder system. When it is found that the sprinkler system in the current fire area fails and the fire sprinkling effect fails to achieve the expected fire extinguishing effect, it will automatically alarm for fire extinguishing and rescue, and remind the captain to make a judgment.

[0012] Further, it also includes an escape reminder system. The escape reminder system can guide the safe escape route and guide the personnel in the fire area to escape safely nearby; it can also comprehensively analyze and judge that the fire is out of control, or the fire extinguishing in key areas fails and may lead to risks such as explosion, and automatically give an audible and visual alarm to abandon the ship, switch the escape equipment, and guide the crew to escape or abandon the ship according to the instructions.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The present invention makes up for the lack of functions in the traditional system, such as no prevention function, no remedy function, no re-ignition monitoring function, no automatic start function for fire extinguishing, and no judgment function for escape. It has considered all aspects from design, prevention, monitoring, remedy, to escape / abandon ship, and uses new technologies such as thermal imaging and AI integration to maximize the protection of vehicle safety, property, and personal safety; with comprehensive and powerful functions, it realizes the all-round intelligent design of the sprinkler fire extinguishing system.

The purpose is to detect the occurrence of a fire faster than the external temperature fire alarm probe at the early stage of the fire and make a rapid response, so as to be able to carry out fire extinguishing operations during the golden fire extinguishing time at the early stage of the fire.

[0023] Design a CCTV system for thermal imaging monitoring to monitor the temperature change of the garage deck. When the camera detects abnormal temperature, it will trigger the alarm of the CCTV workstation. Timely eliminate new energy vehicles that may catch fire.

[0024] Through a temperature measurement model, strict calibration and standardized inspection processes, effectively improve the accuracy of temperature measurement. Make the temperature difference fluctuation of temperature measurement small and the stability better; the dual-light fusion technology is superimposed in the thermal imaging, which can present light details and is convenient for judgment. Support flexible multi-rule layout of points, lines, and frames to meet the temperature measurement requirements of key areas and special points.

[0025] When through comprehensive analysis, it is determined that a fire needs to be extinguished in a certain area, the CCTV will transmit the result to the sprinkler system via signal, and at the same time, close the ventilation system to isolate the air and automatically start the sprinkler system to extinguish the fire.

[0026] 2) Analyze the situation of smoke and fire appearing in the picture through a set of AI algorithms.

[0027] Based on the smoke and fire recognition algorithm that deeply combines deep learning and AI: Learn from the global new energy battery vehicle fire extinguishing situations and samples in different climates and environments, and conduct comprehensive analysis, so as to obtain the high-precision smoke and fire recognition algorithm most similar to the current ship. Adopt real-time detection of each frame of raw data and adaptive fast dynamic detection to achieve faster detection and alarm of smoke and fire.

[0028] Through thermal imaging technology and AI monitoring, judge the situation after fire extinguishing, determine whether the fire extinguishing effect has been achieved, prevent misoperation and re-ignition of the battery, and also avoid danger caused by personnel being in it frequently.

[0029] 3) Establish a comprehensive management and loading process to reduce the fire probability of new energy transport ships.
