Description

Technical Field

[0001] The present invention relates to the technical field of safety management of hydrogen refueling stations, and in particular to a hydrogen leakage tracing system based on multi-source information coupling. Background Art

[0002] Hydrogen is colorless and odorless, has strong fugitive properties, and has a low explosion limit, making it difficult to be quickly monitored. Currently, the gas leak monitoring content of hydrogen refueling stations is relatively simple, mainly focusing on the use of combustible gas detectors based on catalytic combustion, infrared optics and other principles, as well as hydrogen detectors based on catalytic combustion, electrochemistry and other principles, to achieve monitoring and alarm for larger leaks, but it is unable to effectively prevent leaks in a timely manner. When a change in the concentration of leaked gas in the environment is detected, the detector will transmit an electrical signal to the console and sound and light alarms according to the set alarm value. This requires the sensor to have circuit structure components, and even construction wiring is required during the installation process, which poses a certain risk of explosion.

[0003] In the process of hydrogen storage, transportation and sales, hydrogen refueling stations involve key equipment or pipelines in systems such as gas unloading, pressurization, hydrogen storage, hydrogenation and release, which pose certain safety risks of gas leakage.

[0004] The hydrogen leakage monitoring of hydrogen refueling stations disclosed in the prior art mainly relies on hydrogen detectors, which are arranged above hydrogen refueling machines, process equipment areas, gas unloading columns and other areas. The hydrogen detectors are used to detect whether hydrogen exists in the area and the detection results are fed back to users.

[0005] Regarding the above-mentioned prior art, the inventors believe that since hydrogen has a low density and is easy to diffuse after leakage, the use of a hydrogen detector can only detect whether hydrogen exists in the area, but it is difficult to accurately determine the specific location where the hydrogen leakage occurs. Summary of the invention

[0006] In order to solve the problem in the prior art that it is difficult to accurately determine the specific location of a hydrogen leak using a hydrogen detector, the present invention proposes a hydrogen leak tracing system based on multi-source information coupling, by using a first detection unit to collect the pressure, flow and temperature of hydrogen at the air inlet and outlet of the hydrogen equipment, and using a second detection unit to collect the pressure, flow and temperature of hydrogen at the air inlet and outlet of each hydrogen station pipeline, the first detection unit and the second detection unit respectively transmit the collected data to the control module, and the processing unit compares the data based on the constructed hydrogen environment mechanism model, and transmits the information of the first detection unit or the second detection unit corresponding to the abnormal data in the comparison result to the user's display, so as to facilitate the user to check the abnormal data in the hydrogen station according to the corresponding information, thereby improving the speed of the user to determine the hydrogen leakage point in the hydrogen station.

[0035] like Figure 1 As shown, the present invention provides a hydrogen leakage tracing system based on multi-source information coupling, comprising:

[0036] A plurality of first detection units are respectively arranged at the air inlet and the air outlet of the hydrogen-facing equipment, and are used to collect first detection information of the hydrogen-facing equipment in real time, wherein the first detection information includes the pressure, flow rate and temperature of hydrogen at the air inlet and the air outlet of the hydrogen-facing equipment;

[0037] A plurality of second detection units are respectively arranged at the air inlet and the air outlet of each hydrogen station pipeline, and are used to respectively collect the second detection information of each hydrogen station pipeline in real time, wherein the second detection information includes the pressure, flow rate and temperature of hydrogen at the air inlet and the air outlet of each hydrogen station pipeline;

[0038] A processing unit is used to receive the first detection information and the second detection information, and compare them based on a pre-built hydrogen environment mechanism model. If there is abnormal data in the comparison result, the information of the first detection unit or the second detection unit that generates the abnormal data is transmitted to the user's display screen.

[0039] The first detection unit is used to detect the pressure, flow rate and temperature of hydrogen at the air inlet and outlet of the hydrogen-containing equipment. The first detection unit may include a pressure sensor, a speed sensor and a temperature sensor; the pressure sensor is used to measure the pressure of the hydrogen flowing at the air inlet and outlet of the hydrogen-containing equipment, and the speed sensor is used to measure the speed of the hydrogen flowing at the air inlet and outlet of the hydrogen-containing equipment, and the flow rate of hydrogen at the air inlet and outlet of the corresponding hydrogen-containing equipment is obtained in combination with the inner diameter of the pipeline at the air inlet and outlet of the hydrogen-containing equipment; the temperature of the hydrogen at the air inlet and outlet of the hydrogen-containing equipment is measured by the temperature sensor, and the obtained pressure, flow rate and temperature are transmitted to the processing unit, so that the processing unit can obtain the movement of hydrogen at the air inlet and outlet of the hydrogen-containing equipment in real time.

[0040] The second detection unit can also be implemented as a pressure sensor, a speed sensor and a temperature sensor. The pressure sensor is used to measure the pressure of the hydrogen flowing at the air inlet and outlet of the pipeline of each hydrogen refueling station. At the same time, the speed sensor is used to measure the speed of the hydrogen flowing at the air inlet and outlet of the pipeline of each hydrogen refueling station. In combination with the inner diameter of the pipeline at the air inlet and outlet of each hydrogen refueling station pipeline, the flow rate of hydrogen at the air inlet and outlet of the pipeline corresponding to each hydrogen refueling station is obtained; the temperature sensor is used to measure the temperature of the hydrogen at the air inlet and outlet of the pipeline of each hydrogen refueling station, and the obtained pressure, flow rate and temperature are transmitted to the processing unit, so that the processing unit can obtain the movement of hydrogen at the air inlet and outlet of each hydrogen refueling station pipeline in real time.

[0041] The processing unit can be implemented as a processor, which may be a central processing unit (CPU), or other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. It is the computing core and control core of the terminal, which is suitable for implementing one or more instructions, specifically suitable for loading and executing one or more instructions in a storage medium to implement the corresponding method flow or corresponding functions, so as to implement the steps in the above embodiments.

[0042] The processing unit is used to receive the first detection information of each first detection unit and the second detection information transmitted by each second detection unit, so as to obtain the distribution of hydrogen in the hydrogen equipment in the hydrogen refueling station and in the pipeline of each hydrogen refueling station, and compare them based on the pre-built hydrogen environment mechanism model, and judge the abnormal data in the first detection information or the second detection information according to the comparison result to obtain the abnormal data.

[0043] Abnormal data refers to real-time detection information that exceeds or falls below a threshold value of distribution in hydrogen-prone equipment or pipelines of multiple hydrogen refueling stations when no hydrogen leakage occurs. This indicates that a hydrogen leakage may occur at the installation location of the first detection unit or the second detection unit that provides abnormal data to the processing unit, or that the first detection unit or the second detection unit at the corresponding installation location detects and sends erroneous information due to its own fault. At this time, the information of the first detection unit or the second monitoring unit corresponding to the abnormal data is transmitted to the user's display screen through the processing unit, so that the user can obtain the pipeline inspection of the abnormal area in time, improve the efficiency of the user in obtaining the location of hydrogen leakage in the hydrogen refueling station, and also facilitate the user to accurately locate the location of hydrogen leakage in the hydrogen refueling station.

[0044] The present application utilizes a first detection unit to collect the pressure, flow rate and temperature of hydrogen at the air inlet and outlet of hydrogen-prone equipment, and utilizes a second detection unit to collect the pressure, flow rate and temperature of hydrogen at the air inlet and outlet of each hydrogen refueling station pipeline. The first detection unit and the second detection unit respectively transmit the collected data to the control module, and the processing unit compares the data based on the constructed hydrogen environment mechanism model. The information of the first detection unit or the second detection unit corresponding to the abnormal data in the comparison result is transmitted to the user's display, so as to facilitate the user to check the abnormal data in the hydrogen refueling station according to the corresponding information, thereby improving the speed at which the user determines the hydrogen leakage point in the hydrogen refueling station.

[0045] In some embodiments, in order to facilitate users to accurately determine whether there is a hydrogen leak at the location corresponding to the abnormal data transmitted by the processing unit, the hydrogen leak tracing system based on multi-source information coupling provided by the present application also includes:

[0046] A plurality of hydrogen leakage detection units, respectively arranged at each of the first detection units and each of the second detection units, for detecting leakage of hydrogen in the area;

[0047] The plurality of first alarm units are used to respectively receive the hydrogen leakage information transmitted by each hydrogen detection unit. When a hydrogen leakage detection unit detects the presence of hydrogen leakage, the first alarm unit in the corresponding area sends out a first alarm signal.

[0048] The hydrogen leak detection unit can be implemented as a hydrogen leak sensor, and each hydrogen leak detection unit corresponds to an installation position of a first detection unit or a second detection unit. For example, when a hydrogen leak occurs in a pipeline of a hydrogen refueling station, the processing unit identifies the second detection information transmitted by the second detection unit at the corresponding installation position as abnormal data, and transmits the installation information of the corresponding second detection unit to the user's display. At the same time, the hydrogen leak detection unit set at the corresponding position detects the hydrogen that escapes to the outside, and transmits the corresponding electrical signal to the first alarm unit. The user is prompted by the first alarm unit that there is a hydrogen leak in the corresponding area. According to the information transmitted by the hydrogen leak unit and the first alarm unit, it is convenient for the user to eliminate the malfunction of the second detection unit in the area where he is, and then promptly deal with the hydrogen leak in the corresponding area.

[0049] In some embodiments, in order to facilitate users to obtain hydrogen leakage information in their area in a timely manner, the first alarm unit provided by the present application may include:

[0050] a speaker for issuing a warning as an audible warning when a hydrogen leak detection unit in the area detects the presence of a hydrogen leak;

[0051] The warning light is used to turn on or flash as a light warning when the hydrogen leak detection unit in the area detects the presence of hydrogen leakage.

[0052] Each speaker is electrically connected to a hydrogen leak detection unit in the area where it is located, and the warning light is also electrically connected to the same hydrogen leak detection unit in the area. When the hydrogen leak detection unit detects hydrogen leakage in the corresponding area, it transmits an electrical signal to the corresponding speaker and warning light, the corresponding speaker makes a sound, and the warning light flashes, thereby reminding the user.

[0053] In some embodiments, it also includes:

[0054] The second alarm unit is communicatively connected to the processing unit, and is used to send out a second alarm signal when there is abnormal data in the comparison result transmitted by the processing unit.

[0055] Exemplarily, in order to facilitate users to obtain hydrogen leakage information in their area in a timely manner, the second alarm unit provided in the present application can also be set as a speaker and a warning light. When the processing unit detects that there is an abnormality in the comparison result of the operating status data of the hydrogen in the pipeline, a corresponding control command is generated, and the corresponding control command is transmitted to the speaker and the warning light, thereby reminding the user to promptly determine the location of the suspected hydrogen leakage through the display, and at the same time, the hydrogen leakage detection unit in the area is detected to check whether the hydrogen leakage detection unit is faulty or the first detection unit and the second detection unit are faulty.

[0056] In some embodiments, in order to facilitate the judgment of the leakage of hydrogen in the pipeline of the hydrogen refueling station based on the hydrogen distribution state in the hydrogen refueling station, the hydrogen leakage tracing system based on multi-source information coupling provided by the present application also includes:

[0057] The model building unit is communicatively connected to the processing unit and is used to establish a hydrogen environment mechanism model for simulating the hydrogen equipment and hydrogen distribution in each pipeline of the hydrogen refueling station based on the first detection information and the second detection information of the historical records obtained under normal conditions and using a reinforcement learning algorithm.

[0058] The model building unit is used to construct a hydrogen environment mechanism model for describing the hydrogen equipment and hydrogen distribution in each pipeline of the hydrogen filling station when no hydrogen leakage occurs based on the first detection information and the second detection information of the historical records under normal circumstances (i.e., no hydrogen leakage occurs), through the state equation and the continuity equation, combined with the inner diameter size of each pipeline in the hydrogen filling station, and using the airbag learning algorithm. The model is used to judge the first detection data obtained by the subsequent first detection information and the second detection data obtained by the second detection information, so as to identify the abnormal values ​​in the first detection data and the second detection data, and obtain the corresponding area where hydrogen leakage occurs based on the abnormal values.

[0059] Reference Figure 2 In some embodiments, the processing unit includes:

[0060] An information receiving module, used for receiving first detection information sent by each of the first detection units and second detection information sent by each of the second detection units;

[0061] An information comparison module, used to compare the first detection information and the second monitoring information using a pre-built hydrogen environment mechanism model to obtain a comparison result;

[0062] The result evaluation module is used to determine whether there is abnormal data in the comparison result. If there is abnormal data in the comparison result, the information of the first detection unit or the second detection unit that generates the abnormal data is transmitted to the display; if there is no abnormal data in the comparison result, it is output that there is no hydrogen leakage in the corresponding hydrogen refueling station.

[0063] Exemplarily, the input end of the information receiving module is communicatively connected to each first detection unit and the second detection unit, the input end of the information comparison module is communicatively connected to the output end of the model building unit and the output end of the information receiving unit respectively, and the result evaluation module is communicatively connected to the output end of the information comparison unit.

[0064] In some embodiments, the processing unit further includes:

[0065] The data storage module is communicatively connected with the information receiving module and is used for storing the first detection information and the second detection information received by the information receiving module.

[0066] Exemplarily, the data storage module can be implemented as a memory card, which stores the first detection information and the second detection information received by the information receiving module in its own internal space, so as to realize subsequent detection of the operating status of the hydrogen leakage tracing system based on multi-source information coupling provided by the present invention, thereby reducing the probability of errors occurring in the operation of the hydrogen leakage tracing system based on multi-source information coupling.

[0067] In some embodiments, in order to facilitate users to replace or repair hydrogen leaking pipes, the hydrogen leakage tracing system based on multi-source information coupling provided by the present invention also includes:

[0068] A plurality of blocking valves are respectively arranged on one side of each hydrogenation station pipeline close to the hydrogenation equipment, and are used to cut off or connect the hydrogen supplied from the hydrogenation equipment to the corresponding pipeline.

[0069] The blocking valve can be implemented as a solenoid valve. When a suspected hydrogen leak is detected in any hydrogen station pipeline, the blocking valve is closed to isolate the hydrogen input in the corresponding hydrogen station pipeline, reducing the probability of explosion hazard due to hydrogen leakage. At the same time, it is convenient for users to remotely control the hydrogen transportation situation in each hydrogen station pipeline, thereby improving the user's response speed.

[0070] In some embodiments, it also includes:

[0071] A plurality of valve status display modules are respectively arranged at each of the blocking valves, and are used to detect the operating status of each blocking valve, and transmit the detected operating status of each blocking valve and the corresponding information of the blocking valve to the user's display screen.

[0072] The operating status of each plugging valve is detected by the valve status display module and transmitted to the user's display, so that after the user operates the plugging valve at each hydrogen station pipeline, it can be determined whether the plugging valve in the corresponding area is operating normally, thereby improving the maintenance speed of the hydrogen station.

[0073] The implementation principle of the hydrogen leakage tracing system based on multi-source information coupling provided by the present invention is: by using the first detection unit to collect the pressure, flow and temperature of hydrogen at the air inlet and outlet of the hydrogen equipment, and at the same time using the second detection unit to collect the pressure, flow and temperature of hydrogen at the air inlet and outlet of the pipeline of each hydrogen refueling station, the first detection unit and the second detection unit respectively transmit the collected data to the control module, and use the processing unit to compare based on the constructed hydrogen environment mechanism model, and transmit the information of the first detection unit or the second detection unit corresponding to the abnormal data in the comparison result to the user's display, so as to facilitate the user to check the abnormal data in the hydrogen refueling station according to the corresponding information, and improve the speed of the user to judge the hydrogen leakage point in the hydrogen refueling station.
