Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply vehicle technology, specifically to a power supply vehicle with status monitoring and leakage visualization and location functions. Background Technology
[0002] As an important emergency mobile power supply equipment, electric vehicles are gradually incorporating clean and efficient hydrogen fuel cells as their power generation units. The operation of hydrogen fuel cells relies on an onboard hydrogen storage system to supply hydrogen. However, hydrogen is flammable, explosive, and highly prone to leakage; ensuring the safety of the hydrogen storage system is the primary prerequisite for the widespread application of hydrogen-powered electric vehicles.
[0003] Existing hydrogen leak monitoring methods for power vehicles mostly rely on a small number of sensors distributed throughout the cabin. When a sensor alarms, staff can only know that a leak has occurred, but cannot quickly and accurately determine which hydrogen storage tank, valve, or connecting pipeline is leaking. For complex cylinder groups consisting of multiple hydrogen storage tanks, locating leaks requires staff to check all possible leak points one by one, which is time-consuming, inefficient, and can delay response in emergencies, posing significant safety risks. Utility Model Content
[0004] The purpose of this invention is to provide a power vehicle with status monitoring and leak visualization and location functions, which solves the problem that existing hydrogen leak detection technologies can only alarm and cannot achieve real-time and accurate location of the leak point.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A power supply vehicle with condition monitoring and leak visualization and location functions includes:
[0007] A hydrogen storage chamber, which contains a hydrogen storage system; the hydrogen storage system includes a frame and multiple hydrogen storage tanks; the multiple hydrogen storage tanks are arranged in rows and stacked on the frame.
[0008] The status monitoring system includes a control unit, an alarm, a power supply, a display, and multiple hydrogen sensors;
[0009] The alarm, the power supply, the display, and the plurality of hydrogen sensors are all electrically connected to the control unit;
[0010] The multiple hydrogen sensors are evenly distributed on the upper, lower, left, right and front and back areas of the inner wall of the hydrogen storage chamber to form a three-dimensional spatial sensing and detection network surrounding the hydrogen storage system, so as to realize the full-area monitoring of the hydrogen concentration in the hydrogen storage chamber.
[0011] The control unit is configured to: automatically generate a corresponding three-dimensional cabin monitoring model based on the spatial coordinate relationship of the three-dimensional spatial sensing and detection network, and display it on the display in real time; when any of the hydrogen sensors detects a hydrogen leak signal, the control unit controls the alarm to issue an alarm and simultaneously displays a visual alarm indication at the corresponding position on the three-dimensional frame model on the display.
[0012] A further technical solution is that the visual alarm indication is indicated by flashing or changing color at the location corresponding to the leak point in the three-dimensional frame model.
[0013] A further technical solution is that the display is a touch screen, and it supports rotating, scaling, and partial magnification of the three-dimensional cabin monitoring model in order to observe the leakage status from different angles or levels.
[0014] A further technical solution is that the hydrogen sensor is an electrochemical hydrogen sensor or a semiconductor hydrogen sensor.
[0015] A further technical solution is that the status detection system also includes a pressure sensor; the pressure sensor is installed on the inner wall of the hydrogen storage chamber and electrically connected to the control unit, and is used to monitor the gas pressure changes in the hydrogen storage chamber in real time and display them synchronously on the display.
[0016] A further technical solution is that the status detection system also includes a temperature sensor; the temperature sensor is installed on the inner wall of the hydrogen storage tank and electrically connected to the control unit, used to monitor the temperature distribution and abnormal temperature rise in the hydrogen storage tank, and displayed on the display in the form of visual data.
[0017] A further technical solution is that the control unit is also communicatively connected to a remote monitoring terminal; the remote monitoring terminal can receive alarm information and status data of the three-dimensional cabin monitoring model in real time, and upload them to the remote management platform.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] This application constructs a three-dimensional spatial sensing and detection network surrounding the hydrogen storage system by uniformly deploying multiple hydrogen sensors on the inner wall of the hydrogen storage chamber. The control unit then generates a corresponding three-dimensional chamber monitoring model based on the sensor spatial coordinates, achieving real-time monitoring of the hydrogen concentration throughout the chamber. When an abnormal leak signal is detected, the control unit can simultaneously trigger an audible and visual alarm and display a visual prompt at the corresponding location on the monitor, enabling operators to quickly identify the leak area.

Detailed Implementation
[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] Example:
[0026] like Figures 1-2 As shown, this utility model provides a power vehicle with status monitoring and leakage visualization and location functions, including a hydrogen storage tank 1 and a status detection system 2; the hydrogen storage tank 1 is used to install a hydrogen storage system, which includes a frame 11 and multiple hydrogen storage tanks 12; the frame 11 is composed of a base frame 111, columns 112 and transverse connecting parts 113, and multiple hydrogen storage tanks 12 are arranged in layers along the direction of the columns 112 and fixed between the transverse connecting parts 113 by fasteners to form a stable tank array structure.
[0027] The status detection system 2 includes a control unit 21, an alarm 22, a power supply 23, a display 24, and multiple hydrogen sensors 25. The hydrogen sensors 25 are distributed on the upper wall, lower wall, left side wall, right side wall, and front and rear walls of the hydrogen storage chamber 1 to form a three-dimensional sensing and detection network covering the space surrounding the hydrogen storage system.
[0028] The control unit 21 is installed in the electrical control box (not shown in the figure) outside the hydrogen storage tank 1, and is used to collect, analyze and visualize the detection signals of each hydrogen sensor 25; the alarm 22 is located on the outer surface of the electrical control box, close to the operating area, and is used to issue an audible and visual alarm when a leak is detected; the power supply 23 is fixed at the bottom of the electrical control box to provide a stable power supply for the status detection system 2; the display 24 is installed on the front panel of the electrical control box and is used to display the three-dimensional monitoring model and hydrogen concentration distribution generated by the control unit 21 in real time.
[0029] When the power vehicle is in operation, the hydrogen sensor 25 detects the hydrogen concentration in the hydrogen storage tank 1 in real time and transmits the detection signal to the control unit 21. The control unit 21 collects and compares the signals from each detection point, calculates the three-dimensional coordinate information of the sensor, establishes a three-dimensional spatial monitoring model corresponding to the sensor layout, and displays it on the display 24 in real time.
[0030] When any hydrogen sensor 25 detects that the hydrogen concentration exceeds the preset safety threshold, the control unit 21 triggers the alarm 22 to issue an audible and visual alarm. At the same time, the corresponding sensor point is visually indicated in the three-dimensional model on the display 24 by flashing or changing color, so that the operator can intuitively judge the approximate location of the leak.
[0031] This allows operators to quickly identify the leak location via the display interface without having to manually inspect each hydrogen storage tank 12, valve, or pipeline, thus improving emergency response efficiency.
[0032] In this embodiment, the display 24 is a touch-screen liquid crystal display, which can rotate, scale, and magnify the three-dimensional spatial model. The operator can observe the status of the hydrogen storage system from different angles and at different levels as needed, thereby realizing multi-view analysis of potential leakage areas.
[0033] In practical operation, the control unit 21 maps the detection signals based on the spatial distribution coordinates of each hydrogen sensor 25 in the hydrogen storage chamber 1. When a certain local sensor group continuously outputs abnormal signals, the system can calculate the approximate spatial location of the leak source through interpolation algorithm and mark it in the three-dimensional model, making the positioning results more accurate.
[0034] In this embodiment, the status detection system 2 also includes a pressure sensor 26 and a temperature sensor 27; the pressure sensor 26 and the temperature sensor 27 are both arranged on the inner wall of the hydrogen storage tank 1 and are electrically connected to the control unit 21; the control unit 21 receives and comprehensively analyzes the hydrogen concentration, tank pressure and temperature data, and displays them in the form of graphs or curves on the display 24, so that the operator can monitor multiple status changes in the tank at the same time.
[0035] For example, when the hydrogen concentration in a certain area increases while the pressure drops abnormally, the system can determine that there may be a small leak, thus providing maintenance personnel with a basis for locating it. This design not only helps to detect leak trends in advance, but also facilitates the subsequent analysis of gas diffusion patterns under different operating conditions.
[0036] In this embodiment, the control unit 21 is also communicatively connected to the remote monitoring terminal 3. When the control unit 21 detects an abnormal status signal, it can transmit alarm data, sensor numbers, and the visualized status of the three-dimensional cabin monitoring model to the remote monitoring center in real time via the wireless communication module, so as to realize remote monitoring and remote emergency response.
[0037] The remote monitoring terminal 3 can be a host computer system or a mobile monitoring terminal. It displays alarm information through a network platform and can automatically generate safety logs and warning records based on changes in on-site data. In this way, remote synchronization of the power supply vehicle's operating status and linkage with the management system are achieved.
[0038] In this embodiment, the hydrogen sensor 25 can be an electrochemical or semiconductor hydrogen sensor 25; the electrochemical hydrogen sensor 25 can provide high detection sensitivity in a low concentration range; the semiconductor sensor is suitable for long-term stable monitoring; depending on the power vehicle's operating environment and cabin structure, the two types of sensors can be flexibly combined to balance accuracy and response speed.
[0039] In addition, the sensors are connected to the control unit 21 via explosion-proof cables, and the interior of the hydrogen storage chamber 1 is made of fire-resistant and heat-insulating materials to ensure that the system can still operate stably under abnormal conditions.
[0040] Technical effects:
[0041] This application constructs a three-dimensional spatial sensing and detection network surrounding the hydrogen storage system by uniformly deploying multiple hydrogen sensors 25 on the inner wall of the hydrogen storage chamber 1. The control unit 21 generates a corresponding three-dimensional chamber monitoring model based on the sensor spatial coordinates, achieving real-time monitoring of the hydrogen concentration within the chamber. When an abnormal leak signal is detected, the control unit 21 simultaneously triggers an audible and visual alarm and displays a visual prompt at the corresponding location on the display 24, enabling operators to quickly identify the leak area. Combined with the pressure sensor 26 and temperature sensor 27, the system can comprehensively display the changes in chamber pressure and temperature, assisting in judging the leak trend and safety status. Simultaneously, the remote monitoring terminal 3 can achieve synchronous transmission of alarm data and remote response. This technical solution effectively solves the problem of existing hydrogen leak monitoring systems in power vehicles only providing alarms and lacking precise location capabilities, achieving rapid leak point identification, visualization of the chamber's status, and a significant improvement in operational safety.
[0042] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
