[0002] Considering the inherent hazards of hydrogen refueling station operations, it is necessary to monitor these stations to improve safety.

[0082] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0083] A hydrogen refueling station typically comprises multiple operational areas, such as entry / exit areas, refueling areas, unloading areas, and central control areas. Various operations occur at different times. For example, in the refueling area, staff operate hydrogen dispensers to refuel vehicles; in the unloading area, long-tube trailers unload hydrogen; in the central control area, staff monitor and control operations; and there may even be onboard personnel moving around. In short, hydrogen refueling stations involve diverse operations, complex personnel, and large activity areas. In this context, relying on manual inspections to monitor and identify the safety of personnel, vehicles, and equipment at the refueling station results in a high rate of error, a large workload, and low timeliness. Furthermore, relying solely on data collected from environmental sensors at the refueling station for monitoring is clearly insufficient, leading to low reliability.

[0084] In view of this, in order to monitor the safety influencing factors of each working area in a hydrogen refueling station in real time and provide data support for the automatic identification of safety issues in the station, this invention provides a hydrogen refueling station monitoring method, device, system, computer equipment and storage medium.

[0085] Please see Figure 1This is a schematic diagram of the architecture for monitoring a hydrogen refueling station provided by the present invention. It can be seen that cameras are installed in multiple operating areas of the hydrogen refueling station. Cameras in the entry / exit area are mainly used to collect vehicle information, such as license plate information and entry / exit time. Cameras in the refueling area are mainly used to collect equipment information, vehicle information, and personnel information. Cameras in the unloading area are used to collect equipment information, vehicle information, and personnel information. Cameras in the central control area are used to collect personnel information. Environmental sensors are used to collect environmental information such as physical quantities and real-time values. Data collected by cameras or environmental sensors can be stored and displayed in various forms such as charts. The following section combines... Figure 1 The hydrogen refueling station monitoring method provided in the embodiments of the present invention will be described.

[0086] Example 1

[0087] like Figure 2 The diagram shown is a first flowchart of the hydrogen refueling station monitoring method provided by the present invention, which may include the following steps:

[0088] Step S101: Determine the current operating mode of the target work area within the hydrogen refueling station.

[0089] The target operating area includes one or more of the following: entry / exit area, refueling area, unloading area, and central control area; the operating mode includes at least refueling mode or unloading mode.

[0090] It is understandable that a hydrogen refueling station includes multiple work areas, and the operating conditions of different work areas within the station are not the same. Therefore, when monitoring the target work area of ​​a hydrogen refueling station, it is necessary to first determine its current operating condition so that subsequent processing can be carried out based on that current operating condition.

[0091] In one implementation, taking the refueling condition as an example, it can be determined whether it is a refueling condition by collecting relevant parameters of equipment in the hydrogen refueling station, such as hydrogen dispensers, hydrogen guns, compressors, etc., as well as whether there is an operator holding a hydrogen gun. In another implementation, taking the unloading condition as an example, it can be determined whether it is an unloading condition by collecting relevant parameters of equipment in the hydrogen refueling station, such as unloading columns, compressors, etc.

[0092] It should be noted that the above implementation methods are merely two specific forms of determining the current operating mode of the target working area within the hydrogen refueling station, and should not be construed as limiting the present invention.

[0093] Step S102: Obtain the current image and / or video data corresponding to the current working condition mode.

[0094] When monitoring hydrogen refueling stations, the specific form of the monitoring image can be selected depending on the monitoring object. For example, when it is necessary to extract vehicle license plate information, image data can be acquired; when it is necessary to extract personnel movement information, video data can be acquired. Of course, a combination of image data and video data can also be used, and those skilled in the art can make a reasonable choice based on the specific circumstances of the actual application.

[0095] In one implementation, acquiring the current image and / or video data corresponding to the current operating mode includes: acquiring current image and / or video data collected according to a set period. This invention does not limit the period size for collecting the current image and / or video data; those skilled in the art can set it according to the actual monitoring needs of the hydrogen refueling station.

[0096] Step S103: Extract the monitoring data corresponding to the current operating mode from the current image and / or video data.

[0097] The monitoring data includes vehicle information and personnel information.

[0098] Step S104: Obtain the equipment information corresponding to the current operating mode.

[0099] During the monitoring process at hydrogen refueling stations, the specific content of vehicle, personnel, and equipment information will differ for different operating areas. The following provides the specific content of the extracted vehicle, personnel, and equipment information for different operating areas.

[0100] For the entry and exit area, first vehicle information is extracted from the current image and / or video data, wherein the first vehicle information includes license plate number, entry and exit time, and whether there is temporary parking.

[0101] For the refueling area, first equipment information, second vehicle information, and first personnel information are extracted from the current image and / or video data. The first equipment information includes valve status and instrument readings. The second vehicle information includes the license plate number of the refueling vehicle, refueling start time, and refueling end time. The first personnel information includes operator identity information, operator posture information, operator appearance time, operator departure time, and vehicle occupant activity information.

[0102] For the unloading area, second equipment information, third vehicle information, and second personnel information are extracted from the current image and / or video data. The second equipment information includes valve status, instrument readings, and long-tube trailer information. The third vehicle information includes the license plate number of the refueling vehicle, the unloading start time, and the unloading end time. The second personnel information includes operator identity information, operator posture information, operator appearance time, operator departure time, and vehicle occupant activity information.

[0103] For the central control area, third-person information is extracted from the current image and / or video data, wherein the third-person information includes operator identity information, operator posture information, operator appearance time, and operator departure time.

[0104] It should be noted that the above is a preferred implementation of the present invention. The information regarding vehicles, personnel, and equipment is not limited to the specific content listed above, and may also include other information. Those skilled in the art can make reasonable settings according to actual applications. In addition, the information regarding vehicles, personnel, and equipment may also be all or part of the information listed above. Those skilled in the art can make settings according to the specific circumstances of actual applications to reduce the amount of data processed.

[0105] Furthermore, in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0106] Step S105: Conduct safety monitoring of the target work area based on the monitoring data and the equipment information.

[0107] In one implementation, the target work area can be monitored for safety in the following manner:

[0108] Based on the monitoring data and the equipment information, a preset condition check is performed on the current working condition mode of the target work area; if the result of the preset condition check is abnormal, a misoperation check is performed based on the personnel information within a preset time period; if the result of the misoperation check is that a misoperation exists, a misoperation reminder signal is generated; if the result of the misoperation check is that no misoperation exists, an interlocking protection measure notification signal is generated.

[0109] It should be noted that corresponding operating condition modes are established for each work area, and each operating condition mode is constructed in the form of "work area + monitoring data / other information + operation steps and detection conditions". The specific details of performing preset condition checks on the current operating condition mode of the target work area based on monitoring data and equipment information are listed below.

[0110] For gas refueling conditions :

[0111] ①Working area: Refueling area;

[0112] ② Monitoring data: Fuel cell vehicles obtain license plate information, vehicle parking location, operator identification information, operator posture, hydrogen concentration sensor, valve status, instrument readings such as pressure gauge pressure value, etc.

[0113] ③ Operating procedures and testing conditions:

[0114] A. When a vehicle is detected entering the refueling area, the license plate of the fuel cell vehicle is recognized based on the current image and / or video data to verify whether the license plate information matches the vehicle records identified and stored in the entry / exit area or other operating areas.

[0115] B. If a match is found, the fuel cell vehicle stops. Based on the current image and / or video data, the vehicle's location information is obtained, and it is detected whether the vehicle's location information is within a preset designated area. Based on the association between the obtained license plate information and the hydrogen refueling machine, the valve identifier of the corresponding valve is determined.

[0116] C. Obtain operator identity information and operator posture information based on current image and / or video data to determine whether the operator has completed the electrostatic discharge operation and to record whether there are any abnormal actions.

[0117] D. Detect the operator's posture and vehicle information based on the current image and / or video data, and identify whether the following operations are performed: pick up the hydrogen refueling gun - open the refueling port - insert the gas receiver into the vehicle, and record whether the operator's refueling operation is complete and whether there are any abnormal actions based on the operator's identification information.

[0118] E. Detect whether the operator performs the action of pulling out the hydrogen refueling gun and putting it back into the hydrogen refueling machine based on the current image and / or video data; generate the operator's action trajectory based on the aforementioned operator records, and detect whether the operator has any abnormal actions by judging whether the action trajectory is correct for the gas refueling condition.

[0119] F. During the execution of steps E and F, periodically detect, collect and store equipment information, and determine whether the recorded equipment information, such as the fluctuation of the pressure gauge value, exceeds the set threshold.

[0120] G. During the execution of steps E and F, periodically detect whether there is any physical contact between non-operating personnel and the hydrogen refueling equipment based on the current image and / or video data. If so, it is determined that there is an abnormal action.

[0121] It should be noted that during steps A to G above, if an abnormal action is detected, the system can start checking the operator's logs from the moment the abnormality is detected, within the set time period from the beginning of the current step, for any human error. If such error is found, a warning is issued and the system is reassessed until the requirements are met. Otherwise, the hydrogen refueling station control system is notified to take appropriate interlocking measures to ensure safety. Additionally, by checking for anomalies in the operator's movement trajectory and dwell time using image and / or video data, and by using environmental sensors such as hydrogen concentration sensors to determine if the hydrogen concentration exceeds the standard, the system can also determine whether the hydrogen concentration exceeds the limit.

[0122] For unloading conditions :

[0123] ①Working area: Gas unloading area;

[0124] ② Monitoring data: license plate and parking location of long-tube trailer, operator's identity, operator's posture, pressure gauges and valves, etc.;

[0125] ③ Operating procedures and testing conditions:

[0126] a. When a vehicle is detected entering the unloading area, the license plate information of the long-tube trailer is verified based on the current image and / or video data to match the vehicle records identified and stored in the entry / exit area or other operating areas.

[0127] b. If a match is found, the long-tube trailer stops. Based on the current image and / or video data, the vehicle location information of the long-tube trailer is obtained, and it is checked whether the vehicle location information is within a preset designated area. Based on the obtained license plate information and its association with the unloading position, the corresponding valve identifier is determined.

[0128] c. Based on the current image and / or video data, obtain the operator's identity information and operator's posture information to determine whether the operator has completed the connection of the long-tube trailer to the unloading column hose and to record whether there are any abnormal actions.

[0129] d. Determine the sealing of the pressure gauge hose connection based on the pressure value in the equipment information, and whether the termination conditions have been met (which can be set according to safety and quality). Determine the state of the valves in the equipment record to see if the nitrogen inlet line is open when purging begins and if the nitrogen inlet line is closed and the venting line is open when purging ends. Determine the start and end of the nitrogen purging in sequence to ensure that the nitrogen purging process is complete. Detect any hydrogen leaks and record any abnormal actions.

[0130] Accordingly, based on the current image and / or video data, it detects whether the operator has performed the action of opening the main valve of the tube bundle vehicle, and then determines the start and end of the hydrogen purging process based on the pressure value of the pressure gauge. The two sets of data information are combined to determine whether the hydrogen purging process is completely completed. Based on the valve status, it determines whether the operator has performed the action of opening the pneumatic valve. Based on the pressure value of the pressure gauge in the equipment information, it determines the start and end of the unloading process. The two sets of information are combined to determine whether the unloading process is completely completed. After the unloading is completed, it determines whether the pneumatic valve is closed based on the valve status.

[0131] e. Determine whether the venting pipeline valve is open based on the valve status in the equipment information, and determine whether the hydrogen venting has ended based on the pressure value of the pressure gauge in the equipment information; after the venting ends, determine whether the venting valve is closed based on the valve status.

[0132] f. Determine whether the nitrogen inlet valve is open based on the valve status in the equipment information, and determine whether the purging is complete based on the pressure gauge in the equipment record; after completion, determine whether the nitrogen inlet valve is closed based on the valve status.

[0133] It should be noted that at the start of each operation, based on stored data, a step-by-step check is performed according to the operating mode. Key data (monitoring data, equipment information, environmental information, etc.) for each step are jointly analyzed and judged according to timestamps to avoid safety hazards caused by human error and valve malfunction, ensuring the safe operation of all operations within the hydrogen refueling station. During steps a to f above, if an abnormal action is detected, the system checks the operator records from the time the abnormality was detected, starting from the set time period from the beginning of the current step, for any human error. If found, a reminder is issued and the assessment is re-evaluated until the requirements are met; otherwise, the hydrogen refueling station control system is notified to take appropriate interlocking measures to ensure safety.

[0134] The hydrogen refueling station monitoring method provided by this invention first determines the current operating mode of the target work area to be monitored when monitoring the hydrogen refueling station. Then, multiple cameras are used to extract monitoring data corresponding to the current operating mode, and equipment information under the current operating mode is obtained. Based on the above monitoring data and equipment information, the target work area is then monitored for safety.

[0135] Therefore, the hydrogen refueling station monitoring solution provided by this invention utilizes existing image acquisition equipment within the station to collect monitoring data and environmental sensors to collect equipment information, thereby achieving comprehensive and all-weather monitoring of various work areas. Moreover, it can use image recognition technology to obtain information on equipment status changes, vehicle operation trajectories and work process information, and personnel activity trajectories. Furthermore, it collects different data for different working conditions and work areas, realizing real-time monitoring of equipment, vehicles, and personnel in various work areas within the hydrogen refueling station, and providing data support for the automatic identification of safety hazards and dangerous phenomena within the hydrogen refueling station.
