Description

Technical Field

[0001] This invention relates to the field of hydrogen storage and transportation technology, and specifically to a hydrogen storage and transportation safety monitoring system and its monitoring method. Background Technology

[0002] With the rapid development of the hydrogen energy industry and the increasing variety of downstream applications, the demand for large-scale hydrogen energy applications will gradually increase. However, China's hydrogen energy industry is still in its early stages of development and faces many challenges in areas such as hydrogen production, storage, and transportation.

[0003] High-pressure gaseous hydrogen storage has the advantages of low cost, low energy consumption, easy dehydrogenation, and wide operating conditions. It is the most mature and commonly used hydrogen storage technology. It mainly uses four types of gas cylinders made of different materials (Type I, Type II, Type III, and Type IV) as hydrogen storage containers. Gaseous hydrogen is stored through high-pressure compression. However, hydrogen molecules are very small and are prone to leakage during storage and use. The ignition point of hydrogen is only 585°C. When its content in air is in the range of 4% to 75%, it will explode when it comes into contact with an open flame. Therefore, leakage must be monitored during the use of hydrogen.

[0004] Existing hydrogen storage and transportation safety monitoring systems have certain shortcomings. They cannot monitor hydrogen storage containers in real time, and the monitoring ranges set for hydrogen safety monitoring, i.e., the triggered threshold ranges, cannot provide adequate protection. Therefore, this invention proposes a hydrogen storage and transportation safety monitoring system and method to improve upon the aforementioned problems. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology in which the regulatory range set for monitoring the safety of hydrogen, i.e. the threshold range of the trigger, cannot provide better protection, thereby providing a hydrogen storage and transportation safety monitoring system and monitoring method.

[0006] To address the aforementioned problems, this invention provides a hydrogen storage and transportation safety monitoring system and method, comprising a data processing device and a data acquisition device installed on a hydrogen storage container, wherein the data processing device includes:

[0007] The data storage module is used to receive and store various types of data collected by the data acquisition device;

[0008] The analysis and monitoring module is used to fuse the data received by the data storage module and perform real-time monitoring according to the set dynamic threshold range;

[0009] The alarm module is used to issue an alarm when it determines that the data collected in real time from the hydrogen storage container exceeds the set dynamic threshold range.

[0010] A communication module, which is used for sending data.

[0011] In some implementations, a server connected to the communication module is also included for storing various types of collected data and analysis results, receiving alert information, and sending it to the user.

[0012] In some embodiments, the data acquisition device includes a pressure sensor, a temperature sensor, and an attitude sensor. The pressure sensor and the temperature sensor are both disposed inside the hydrogen inlet of the hydrogen storage container and outside the hydrogen storage container to collect pressure data and temperature data inside and outside the hydrogen storage container in real time, respectively. The attitude sensor is disposed on the hydrogen storage container to collect attitude offset data of the hydrogen storage container. The pressure sensor, the temperature sensor, and the attitude sensor are all connected to the data storage module.

[0013] In some embodiments, the data storage module includes a device data module and a work log module. The device data module is connected to the pressure sensor, the temperature sensor, and the attitude sensor, respectively, and the work log module is connected to the device data module.

[0014] In some implementations, the analysis and monitoring module fuses and monitors the data received by the data storage module, including:

[0015] The output data of the data acquisition device is transformed by feature extraction to extract the feature vector Yi representing the observation data. The feature vector Yi is then processed by pattern recognition. The descriptive data about the target in the output data is grouped according to the same target, and the data of each group is synthesized using a fusion algorithm.

[0016] The synthesized data is monitored in real time according to the set dynamic threshold range.

[0017] In some implementations, the alarm module includes a warning light and a horn, the horn and the warning light being connected to the analysis and monitoring module respectively to provide audible and visual warnings.

[0018] In some implementations, the communication module uses LTE technology as the transmission method.

[0019] The present invention also provides a method for monitoring the safety of hydrogen storage and transportation, which uses the monitoring system described in any of the preceding claims to monitor the safety of hydrogen storage and transportation, the method comprising at least:

[0020] The collected data is then fused and processed using data acquisition equipment.

[0021] Set a dynamic threshold range and monitor the threshold of the fused data;

[0022] An alarm is triggered after the monitored data is determined to exceed the dynamic threshold range.

[0023] The communication module transmits alarm results to the server in real time for remote alarm notification.

[0024] In some implementations, the dynamic threshold range is:

[0025] Threshold ranges are set for the data collected by the pressure sensor, temperature sensor, and attitude sensor respectively. The threshold ranges of the pressure sensor, temperature sensor, and attitude sensor are weighted and averaged according to the fusion algorithm to generate the dynamic range of the fused data.

[0026] The hydrogen storage and transportation safety monitoring system and method provided by this invention have the following beneficial effects:

[0027] 1. This invention enables the storage and transportation equipment of hydrogen to be monitored in real time by pressure sensors, temperature sensors and attitude sensors, and is equipped with a data storage module, analysis and monitoring module, alarm module and communication module, so that data can be viewed anytime and anywhere, and multiple terminals can be monitored together.

[0028] 2. The present invention also performs a weighted average of the threshold ranges of the pressure sensor, temperature sensor and attitude sensor, and sets different weights so that dynamic threshold range monitoring can be performed after the data of the three sensors are fused. This range is closer to the safety performance monitoring of hydrogen. Attached Figure Description

The attitude sensor is installed on the hydrogen storage container to collect attitude offset data of the hydrogen storage container. The pressure sensor, temperature sensor, and attitude sensor are all connected to the data storage module.

[0037] In some embodiments, the storage module includes a device data module and a work log module. The device data module is connected to the data storage module, the temperature sensor, and the attitude sensor, respectively, and the work log module is connected to the device data module. Figure 1As shown, the storage module includes a device data module and a work log module.

[0038] In some implementations, the analysis and monitoring module fuses and monitors the data received by the data storage module, including:

[0039] The output data of the data acquisition device is transformed to extract features, thereby extracting the feature vector Y representing the observed data. i For the feature vector Y i Pattern recognition processing is performed, and the descriptive data about the target in the output data is grouped according to the same target. Then, a fusion algorithm is used to synthesize each group of data.

[0040] The synthesized data is monitored in real time according to a set dynamic threshold range. For example... Figure 1 As shown, the analysis and monitoring module fuses and analyzes the data received by the data storage module as follows:

[0041] The data acquisition device performs feature extraction transformation on the output data from various sensors to extract the feature vector Y representing the observed data. i For the feature vector Y i Pattern recognition processing, such as clustering algorithms, adaptive neural networks, or other methods that can transform the feature vector Y, is performed. i The data is transformed into statistical pattern recognition methods for target attribute judgment, and then the descriptions of each sensor about the target are completed. The description data of each sensor about the target are grouped according to the same target, i.e., associated. The fusion algorithm is used to synthesize the sensor data of each target, such as a neural network, to obtain a consistent interpretation and description of the target.

[0048] The communication module transmits alarm results to the server in real time for remote alarm notification.

[0049] Specifically, during real-time monitoring, a dynamic threshold range is set. Data collected by pressure sensors, temperature sensors, and attitude sensors are fused and processed. Threshold monitoring is performed on the fused data. If the monitored data exceeds the dynamic threshold range, an alarm is triggered, with flashing warning lights and a horn sounding. The communication module transmits the alarm results to the server in real time for remote alerting, reminding relevant departments to provide timely feedback.

[0050] In some implementations, the dynamic threshold range is:

[0051] Threshold ranges are set for the data collected by the pressure sensor, temperature sensor, and attitude sensor respectively. The threshold ranges of the pressure sensor, temperature sensor, and attitude sensor are weighted and averaged according to the fusion algorithm to generate the dynamic range of the fused data.

[0052] Specifically, the weights for setting the dynamic threshold range can be referenced from historical data, the environment in which the equipment is used, etc. Threshold ranges are set for the data collected by the pressure sensor, temperature sensor, and attitude sensor respectively. The threshold ranges of the pressure sensor, temperature sensor, and attitude sensor are weighted and averaged according to the fusion algorithm to generate the dynamic range of the fused data. This range can be closer to the safety monitoring standards for hydrogen storage and transportation, and the weights of the weighted average can be adjusted at any time.
