Description

Technical Field

[0001] This application relates to the technical field of gas monitoring, and in particular to a visual management method and related equipment for a liquid oxygen station. Background Technology

[0002] Liquid oxygen is oxygen cooled below its boiling point, resulting in a liquid form with a higher density, allowing for the storage of larger quantities within a container. A liquid oxygen station typically refers to a facility used for storing and supplying liquid oxygen. These stations are commonly used to supply oxygen to various applications, including medical facilities, industrial production, and rocket engines.

[0003] With the widespread production and use of liquid oxygen, its storage and filling technologies have developed rapidly. However, the highly flammable, explosive, high-pressure, and low-temperature properties of liquid oxygen pose safety hazards during storage and filling. Personnel need to promptly understand and monitor the operating status and data of each liquid oxygen tank to ensure the safe supply of oxygen to liquid oxygen stations.

[0004] In existing technologies, the safety monitoring of liquid oxygen storage and filling mainly relies on manual inspections and on-site monitoring by on-site personnel, requiring regular manual inspections and recording. However, this on-site monitoring method suffers from problems such as poor timeliness, failing to reflect the real-time operating status of the liquid oxygen station in a timely manner, and making it difficult to promptly detect and address safety hazards. This situation needs to be improved. Summary of the Invention

[0005] To address the issue of poor timeliness in existing liquid oxygen station monitoring methods, this application provides a visual management method and related equipment for liquid oxygen stations, employing the following technical solution:

[0020] Optionally, determining whether the target liquid oxygen tank has any abnormalities based on the current state parameters includes:

[0021] Determine whether the current state parameter falls within the range of the standard state parameter;

[0022] If the current state parameter falls within the range of the standard state parameter, it is determined that the target liquid oxygen tank is not in any abnormal condition.

[0023] If the current state parameter does not fall within the range of the standard state parameter, then the target liquid oxygen tank is determined to have an abnormal condition.

[0024] Optionally, displaying the online device information, the anomaly information within the current period, and the output air pressure change trend on the overview page includes:

[0025] Set the summary area and display area on the overview page;

[0026] The online device information and the abnormal information within the current period are displayed in the summary area;

[0027] The trend of output air pressure change is displayed in the display area.

[0028] By adopting the above technical solution,

[0029] Optionally, after displaying N navigation tabs in the navigation area of ​​the visual control interface, the method further includes:

[0030] The monitoring page corresponding to the monitoring navigation tag is displayed according to the user's third navigation instruction, and the monitoring navigation tag is one of the N navigation tags;

[0031] Real-time acquisition of status information, liquid level value, and gas pressure value of each of the M liquid oxygen tanks;

[0032] On the monitoring page, set the monitoring area corresponding to each of the M liquid oxygen tanks;

[0034] Optionally, after displaying N navigation tabs in the navigation area of ​​the visual control interface, the method further includes:

[0035] The data page corresponding to the data navigation label is displayed according to the user's fourth navigation instruction. The data navigation label is one of the N navigation labels. The data page includes a periodic display area and a prompt information display area.

[0036] The target period identifier in the period display area is determined based on the user's data query instruction;

[0037] Obtain the alarm information of each of the M liquid oxygen tanks within the period corresponding to the target period identifier;

[0038] The alarm information of each of the M liquid oxygen tanks is displayed in the prompt information display area.

[0039] Secondly, this application provides a visual management device for a liquid oxygen station, comprising:

[0040] The first display module is used to display N navigation labels in the navigation area of ​​the visual control interface, wherein N is an integer greater than or equal to 1;

[0041] The second display module is used to display the device page corresponding to the device navigation label according to the user's first navigation instruction, wherein the device navigation label is one of the N navigation labels;

The target liquid oxygen tank is the liquid oxygen tank corresponding to any one of the M liquid oxygen tank labels.

[0044] The first judgment module is used to determine whether there is an abnormality in the target liquid oxygen tank based on the current status parameters;

[0045] The first processing module is used to adjust the valve flow rate of the target liquid oxygen tank according to the user's second setting command if the target liquid oxygen tank has the abnormal situation.

[0046] Thirdly, this application provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the above-described visual management method for liquid oxygen stations.

[0047] Fourthly, this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the above-described visual management method for liquid oxygen stations.

[0048] In summary, it can be seen that in the embodiments provided in this application, N navigation labels are displayed in the navigation area of ​​the visual control interface. The page is switched by receiving user commands for any one of the N navigation labels. For example, based on the user's first navigation command, the device page corresponding to the navigation label is displayed, and M liquid oxygen tank labels are displayed on the device page. The target liquid oxygen tank can be viewed by receiving user commands for any one of the M liquid oxygen tank labels. For example, based on the user's first setting command, the real-time monitoring video of the target liquid oxygen tank and its current status parameters are displayed on the device page. Then, the target liquid oxygen tank is determined based on the current status parameters. If any abnormalities are found in the target liquid oxygen tank, the valve flow rate of the target liquid oxygen tank can be adjusted according to the user's second setting command. This can increase, decrease, or close the valve flow rate of the target liquid oxygen tank. Compared with the existing technology that relies on manual inspections by on-site personnel for the management of liquid oxygen stations, which cannot reflect the real-time operating status of the liquid oxygen station in a timely manner, the solution in this application has a visual control interface that can monitor the status of each liquid oxygen tank in the liquid oxygen station in real time. Furthermore, if the target liquid oxygen tank is in an abnormal situation, the valve flow rate of the target liquid oxygen tank can be adjusted according to the user's second setting command. This is conducive to timely detection and handling of safety hazards, thereby solving the problem of poor timeliness in the existing liquid oxygen station monitoring methods.

[0059] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to any or all possible combinations including one or more of the listed items.

[0060] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0061] This application discloses a visual management method for liquid oxygen stations.

[0062] Reference Figure 1 , Figure 1 The flowchart illustrates the visual management method for an oxygen station provided in this application embodiment. The method includes the following steps:

[0063] S10. Display N navigation labels in the navigation area of ​​the visual control interface, where N is an integer greater than or equal to 1;

[0064] Among them, reference Figure 2 , Figure 2 This is a schematic diagram of the visual control interface provided in an embodiment of this application. Figure 2 The 201 in the example represents N navigation labels, such as... Figure 2 As shown, the N navigation tabs include an overview navigation tab, a device navigation tab, a monitoring navigation tab, and a data navigation tab. These N navigation tabs are presented as tab pages, allowing users to see the tabs for different pages at the top or bottom of the interface. This ensures that each navigation tab is associated with a corresponding page, and users can distinguish different pages using tab names, icons, or colors, ensuring easy identification.

[0065] S20. Display the device page corresponding to the device navigation label according to the user's first navigation instruction. The device navigation label is one of N navigation labels.

[0066] Among them, such as Figure 2 As shown, Figure 2 The number 202 in the text refers to the equipment navigation label. Since the equipment navigation label is associated with the equipment page, when the user clicks the equipment navigation label (i.e., the user's first navigation command), the equipment page is displayed. The navigation area is used to display N navigation labels, and the equipment page is used to display detailed information about the liquid oxygen tanks in the liquid oxygen station.

[0067] Specifically, the N navigation labels can be device names, icons, or other identifiers, and the N navigation labels are dynamically displayed on the interface. By associating each navigation label with its corresponding page object (associating device navigation labels with device pages), when the user clicks on a device navigation label, the user is switched to the device page, which displays detailed information about each liquid oxygen tank in the liquid oxygen station.

[0068] In one embodiment, after displaying N navigation labels in the navigation area of ​​the visual control interface, the following steps are further performed:

[0069] The overview page corresponding to the overview navigation tab is displayed according to the user's second navigation command. The overview navigation tab is one of N navigation tabs.

[0070] Obtain the current online equipment information of the liquid oxygen station, the abnormal information within the current period, and the output pressure change trend of the target liquid oxygen tank within a preset time period;

[0071] The overview page displays online device information, abnormal information within the current cycle, and output air pressure change trends.

[0072] In this embodiment, refer to Figure 3 , Figure 3 A schematic diagram of an overview page provided for an embodiment of this application. Figure 3 The "301" in the header refers to the overview navigation tab. When a user clicks the overview navigation tab (i.e., the user's second navigation command), the overview page is displayed. Data is collected from each liquid oxygen tank in the liquid oxygen station, including but not limited to information on currently online equipment (i.e., liquid oxygen tanks), anomaly information within the current period, and the output pressure change trend of the target liquid oxygen tank within a preset time period.

[0073] It should be noted that this data can be acquired through data acquisition devices such as sensors and monitoring equipment, and thresholds can be set to detect abnormal information within the current period, as well as analyze the output pressure data of the target liquid oxygen tank to obtain the output pressure change trend within a preset time period. The online equipment information, abnormal information within the current period, and output pressure change trend are then displayed on the overview page so that users can intuitively observe the status information of each liquid oxygen tank in operation at the liquid oxygen station.

[0074] In one embodiment, displaying online device information, anomaly information within the current period, and output pressure change trends on the overview page includes:

[0075] Set the summary area and display area on the overview page;

[0076] The summary area displays online device information and anomaly information within the current period.

[0077] The trend of output air pressure change is displayed in the display area.

[0078] In this embodiment, as Figure 3 As shown, Figure 3 The 302 in the table is the summary area. Figure 3 The 303 error in the image refers to the display area, which summarizes online device information (such as...). Figure 3 The online devices shown in section 302 are two, and the abnormal information within the current period (such as...) Figure 3 The number of anomalies shown in 302 today is 74. Figure 3 This example uses a 24-hour period for anomaly statistics, but other periods are also possible, such as 48 hours or 7 days. The display area shows the output air pressure change trend. For easier understanding, the following explains the online equipment information, anomaly information within the current period, and the output air pressure change trend:

[0079] The online equipment information includes the number of online devices at the liquid oxygen station, the status of the liquid oxygen tanks, the liquid oxygen tank level, and the liquid oxygen tank pressure. In one embodiment, the number of online devices is the number of liquid oxygen tanks in the liquid oxygen station. For example, if the total number of liquid oxygen tanks in operation today is X, then the online equipment information displays the number X, where X is an integer equal to or greater than 1.

[0080] In one embodiment, reference is made to Figure 4 , Figure 4 This is a schematic diagram of the "Cut Can" pop-up window in the overview page provided in this application embodiment. Figure 4 The 401 in the text refers to the can-switching label. This label is set in the summary area and switches according to the user's can-switching instructions. Figure 4The 402 error message indicates a tank-switching pop-up. After selecting the tank to be switched and clicking "Confirm," the tank-switching operation is complete. It's important to note that the tank-switching operation encapsulates multiple valve operations; the logic is to close the output valve of the currently used liquid oxygen tank and open the output valve of another liquid oxygen tank. To facilitate understanding, the tank-switching operation is illustrated below with an example:

[0081] Since the interface displays equipment data for each liquid oxygen tank in the liquid oxygen station, if the liquid level and / or pressure of a currently operating liquid oxygen tank falls below a certain threshold, a prompt message will be issued, prompting the user to perform a tank switching operation. Alternatively, the user can actively perform a tank switching operation while viewing the liquid level and / or pressure values. After the user operates the tank switching button shown in 401, the interface shown in 402 will be displayed. The user can perform a tank switching operation by selecting options on the interface shown in 402. For example, if the currently online equipment includes liquid oxygen tank 0 and liquid oxygen tank 1, where liquid oxygen tank 0 is in operating mode and liquid oxygen tank 1 is in standby mode, after receiving the user's tank switching operation, the operating status of liquid oxygen tank 0 will be adjusted to the off state, and liquid oxygen tank 1 will be adjusted to the operating state. Compared to existing technologies, where staff rely on the liquid oxygen tank's level and pressure to determine if its liquid oxygen storage is insufficient during inspections, requiring time-consuming manual tank-switching operations, and potentially leading to oxygen supply disruptions due to low liquid oxygen levels, the solution in this application allows users to clearly understand the status of each liquid oxygen tank through an overview page, and to perform tank-switching operations based on user commands when a liquid oxygen tank's storage is insufficient.

[0082] It is worth noting that the liquid level value indicates the amount of liquid oxygen stored in the liquid oxygen tank, usually expressed as a percentage or the actual liquid level height. The gas pressure value indicates the gas pressure inside the liquid oxygen tank, usually expressed in standard atmospheres or other units. To facilitate understanding, the following explanation of how to determine the state of a liquid oxygen tank based on liquid level and gas pressure values ​​is provided:

[0083] Normal state: The liquid level is within the safe range and the gas pressure is within the normal range, indicating that the storage capacity and pressure of the liquid oxygen tank are at normal levels.

[0084] Low liquid level: A liquid level below the safe range may mean that the liquid oxygen tank has insufficient liquid oxygen storage and needs to be replenished in time.

[0085] High liquid level: A liquid level higher than the safe range may indicate an overflow or other problem with the liquid oxygen tank, requiring maintenance.

[0086] Low pressure: A pressure value below the normal range may indicate insufficient gas pressure inside the liquid oxygen tank, requiring inspection for possible leaks or other problems.

[0087] High pressure: A pressure value higher than the normal range may mean that the gas pressure inside the liquid oxygen tank is too high, and it is necessary to check for possible overpressure.

[0088] In one embodiment, after displaying N navigation labels in the navigation area of ​​the visual control interface, the following steps are further performed:

[0089] The monitoring page corresponding to the monitoring navigation label is displayed according to the user's third navigation command. The monitoring navigation label is one of N navigation labels.

[0090] Real-time acquisition of status information, liquid level value, and gas pressure value for each of the M liquid oxygen tanks;

[0091] On the monitoring page, set the monitoring area corresponding to each of the M liquid oxygen tanks;

[0092] The status information, liquid level value, and air pressure value are displayed in the monitoring area.

[0093] In this embodiment, refer to Figure 5 , Figure 5 This is a schematic diagram of a monitoring page provided in an embodiment of this application. Figure 5 501 in the text refers to the monitoring navigation label. The visual control interface receives the user's third-party navigation commands and displays them on the corresponding monitoring page. M monitoring areas are set on the monitoring page, each corresponding to one of the M liquid oxygen tanks. Figure 5 502 in the text refers to the monitoring area of ​​liquid oxygen tank 0. Figure 5 503 in the diagram refers to the monitoring area for liquid oxygen tank 1. This monitoring area contains real-time video recordings of the corresponding liquid oxygen tank, displaying its status information, liquid level, and gas pressure. Figure 5 As shown, 501 is the monitoring area for liquid oxygen tank 0, which displays the status information of liquid oxygen tank 0 as "in use", liquid level as 9.63m, and gas pressure as 0.813MPa; 502 is the monitoring area for liquid oxygen tank 1, which displays the status information of liquid oxygen tank 1 as "standby", liquid level as 8.632m, and gas pressure as 0.481MPa.

[0094] In one embodiment, after displaying N navigation labels in the navigation area of ​​the visual control interface, the following steps are further performed:

[0095] The data page corresponding to the data navigation label is displayed according to the user's fourth navigation instruction. The data navigation label is one of N navigation labels. The data page includes a periodic display area and a prompt information display area.

[0096] The target period identifier in the period display area is determined based on the user's data query command;

[0097] Obtain the alarm information of each of the M liquid oxygen tanks within the period corresponding to the target period identifier;

[0098] The alarm information of each of the M liquid oxygen tanks is displayed in the prompt information display area.

[0099] In this embodiment, refer to Figure 6 , Figure 6 A schematic diagram of a data page provided in an embodiment of this application. Figure 6 The 601 in the text refers to the data navigation label. Figure 6 602 in the image is the periodic display area. Figure 6 603 is the prompt information display area. The periodic display area is shown in 602. The periodic display area has several period identifiers. The target period identifier in the periodic display area is determined according to the user's data query command. The target period identifier is any one of the several period identifiers. The alarm information of each liquid oxygen tank in M ​​liquid oxygen tanks within the period corresponding to the target period identifier is obtained. The prompt information display area 603 is used to display the alarm information.

[0100] In one embodiment, the period display area can be in calendar format, and the period identifier can be a date. For example, if a user needs to obtain the alarm information of each of the M liquid oxygen tanks on the 13th of the current month, the target period identifier is 13. The target period identifier is determined according to the user's query command, and the alarm information within the period corresponding to the target period identifier is displayed in the prompt information display area.

[0101] It should be noted that alarm information includes triggered alarms and all user operation logs. Alarm information refers to notifications of abnormal or dangerous situations detected by the system. Alarm information can include intrusion detection, fire alarms, equipment malfunctions, low liquid levels, high liquid levels, low air pressure, high air pressure, etc. Alarm information provides sufficient detailed information so that administrators or relevant personnel can quickly take appropriate action. Furthermore, it can record all user operations, including logins and data modifications, which helps track system usage and facilitate investigations when problems occur.

[0102] S30. Display the labels of M liquid oxygen tanks on the equipment page, where M is an integer greater than or equal to 1, and the M liquid oxygen tank labels are the labels corresponding to the M liquid oxygen tanks to be managed in the liquid oxygen station.

[0103] Among them, such as Figure 7 As shown, Figure 7 This is a schematic diagram of a device page provided in an embodiment of this application. Figure 7701 represents M liquid oxygen tank labels. These M liquid oxygen tank labels are displayed on the equipment page. The M liquid oxygen tank labels correspond to the M liquid oxygen tanks to be managed at the liquid oxygen station. Providing the M liquid oxygen tank labels on the equipment page helps users view the status information of the corresponding liquid oxygen tanks as needed.

[0104] S40. Based on the user's first setting instruction, display the real-time monitoring video of the target liquid oxygen tank and the current status parameters of the target liquid oxygen tank on the device page. The target liquid oxygen tank is any liquid oxygen tank corresponding to any one of the M liquid oxygen tank labels.

[0105] in, Figure 7 702 in the image refers to the real-time monitoring video. As shown in 702, the current interface is displaying the real-time monitoring video of the liquid oxygen tank 0 selected in 701. Figure 7 703 in the diagram represents the current status parameter of the target liquid oxygen tank. The device page receives the first setting command from the user and displays the monitoring video of the target liquid oxygen tank on the device page according to the first setting command. For example, the current device page displays the monitoring video of liquid oxygen tank A, and also displays the current status parameter of liquid oxygen tank A. If the user needs to view the monitoring video of liquid oxygen tank B, the device receives the user's first setting command, switches the monitoring video of liquid oxygen tank A to the monitoring video of liquid oxygen tank B, and displays the current status parameter of liquid oxygen tank B at the same time.

[0106] S50. Determine whether there is any abnormality in the target liquid oxygen tank based on the current status parameters;

[0107] After obtaining the current status parameters of the target liquid oxygen tank, it is possible to determine whether there are any abnormalities. Key status parameters of the liquid oxygen tank, such as liquid level and gas pressure, need to be considered. A comprehensive assessment of both liquid level and gas pressure is necessary for a more complete evaluation of the tank's condition. For example, a normal liquid level but abnormal gas pressure may indicate other problems requiring further investigation.

[0108] The following example illustrates how to determine if a target liquid oxygen tank has any abnormalities:

[0109] Anomaly 1: If the liquid oxygen level in the target liquid oxygen tank is below the safe range, the system should trigger a low liquid level alarm, indicating that the liquid oxygen storage may be insufficient and needs to be replenished in time.

[0110] 2. If the liquid level is abnormally high, it may indicate an overflow or other problem, requiring maintenance.

[0111] Thirdly, if the gas pressure value of the target liquid oxygen tank is lower than the normal range, it may mean that the internal gas pressure is insufficient, and it is necessary to check for possible leaks or other problems.

[0112] Fourthly, if the air pressure value is abnormally high, it may indicate that the internal gas pressure is too high, and it is necessary to check for possible overpressure.

[0113] Fifthly, compare the current status parameters of the target liquid oxygen tank with historical data to check for any sudden changes or abnormal trends.

[0114] The system monitors the status parameters of the liquid oxygen tank in real time and sets appropriate alarm thresholds. In case of abnormal conditions, the system can trigger an alarm and notify relevant personnel to take necessary measures.

[0115] In one embodiment, before determining whether there is an abnormality in the target liquid oxygen tank based on the current state parameters, the following steps are performed:

[0116] Generate liquid level and pressure data diagrams for the target liquid oxygen tank based on the current state parameters and the standard state parameter range;

[0117] The liquid level data graph and the air pressure data graph are displayed in the status display area of ​​the device page.

[0118] In this embodiment, Figure 7 704 in the text refers to the setting area for the standard state parameter range. Users can set the standard state parameter range for the liquid oxygen tank within this area. Figure 7 As shown, the standard state parameter range includes parameters such as the upper limit of output air pressure, the lower limit of output air pressure, the upper limit of tank air pressure, and the lower limit of tank air pressure. Figure 7 705 in the figure refers to the liquid level data chart. Figure 7 706 in the diagram refers to the pressure data diagram. Based on the current state parameters of the target liquid oxygen tank and the standard state parameter range in setting area 704, the liquid level data diagram and the pressure data diagram are generated and displayed on the equipment page.

[0119] In one embodiment, such as Figure 8 As shown, Figure 8 This is a schematic diagram illustrating the setting of standard parameter ranges provided in an embodiment of this application. After receiving the user's setting parameter command, a parameter preset window pops up. Figure 8 801 in the figure is the parameter preset window, where users can input standard parameters; Figure 8 802 in the code represents the sub-setting area of ​​the standard status parameter range. After receiving a confirmation command from the user, the sub-setting area of ​​the standard status parameter range adjusts the parameters to the standard parameters. Once the adjustment is complete, a pop-up window indicating successful setting appears to notify the user that the standard parameters have been set successfully. Figure 8 The 803 error code indicates a pop-up notification.

[0120] In one embodiment, determining whether the target liquid oxygen tank has an abnormality based on the current state parameters includes:

[0121] Determine whether the current state parameter falls within the standard state parameter range;

[0122] If the current state parameters fall within the standard state parameter range, it is determined that there is no abnormality in the target liquid oxygen tank;

[0123] If the current state parameters do not fall within the standard state parameter range, it is determined that there is an abnormality in the target liquid oxygen tank.

[0124] In this embodiment, the presence of an abnormality in the target liquid oxygen tank is determined by whether the current state parameter falls within the standard state parameter range. If the current state parameter falls within the standard state parameter range, the target liquid oxygen tank is determined to be free of abnormalities. If the current state parameter does not fall within the standard state parameter range, the target liquid oxygen tank is determined to be abnormal. It should be noted that, in order to improve safety, the liquid level value and gas pressure value in the current state parameter need to be comprehensively judged.

[0125] S60. If there is an abnormality in the target liquid oxygen tank, adjust the valve flow rate of the target liquid oxygen tank according to the user's second setting command.

[0126] Specifically, when the target liquid oxygen tank is in an abnormal condition, the valve flow rate is adjusted according to the user's second setting command, such as... Figure 9 As shown, Figure 9 This is a schematic diagram of adjusting the valve flow rate of the target liquid oxygen tank according to an embodiment of this application. The operation of adjusting the valve flow rate includes operations such as increasing, decreasing, closing, and opening. Figure 9 901 in the diagram refers to the throttling valve of the target liquid oxygen tank. Currently, the throttling valve is in the closed state. After receiving the user's second setting command, an adjustment pop-up window will appear. Figure 9 903 in the text refers to the adjustment pop-up window before adjustment.

[0128] In one embodiment, if the liquid oxygen tank malfunctions, an alarm needs to be issued. For ease of understanding, the types of alarms are described below:

[0129] Alarm 1: Liquid oxygen tank level is below preset parameter, requiring tank shut-off.

[0130] Alarm 2: Liquid oxygen tank pressure abnormality (lower or higher than preset parameter) alarm;

[0131] Alarm 3: Liquid oxygen supply is insufficient. Manual reordering of liquid oxygen is required.

[0132] Alarm 4: Total pressure abnormality in liquid oxygen delivery pipeline (lower or higher than preset parameter) alarm.

[0133] The embodiments of this application have been described above from the perspective of a visual management method for liquid oxygen stations. The embodiments of this application will now be described below from the perspective of a visual management device for liquid oxygen stations. Please refer to [link / reference]. Figure 10 , Figure 10 This is a virtual structural diagram of a visual management device for a liquid oxygen station provided in an embodiment of this application. The visual management device 1000 for the liquid oxygen station includes:

[0135] The second display module 1002 is used to display the device page corresponding to the device navigation label according to the user's first navigation instruction. The device navigation label is one of N navigation labels.

[0136] The third display module 1003 is used to display M liquid oxygen tank labels on the device page, where M is an integer greater than or equal to 1, and the M liquid oxygen tank labels are the labels corresponding to the M liquid oxygen tanks to be managed in the liquid oxygen station.

[0137] The fourth display module 1004 is used to display the real-time monitoring video of the target liquid oxygen tank and the current status parameters of the target liquid oxygen tank on the device page according to the user's first setting instruction. The target liquid oxygen tank is any liquid oxygen tank corresponding to any one of the M liquid oxygen tank labels.

[0138] The first judgment module 1005 is used to determine whether there is an abnormality in the target liquid oxygen tank based on the current status parameters.

[0139] The first processing module 1006 is used to adjust the valve flow of the target liquid oxygen tank according to the user's second setting command if there is an abnormality in the target liquid oxygen tank.

[0140] In this embodiment, the first display module displays N navigation tags in the navigation area of ​​the visual control interface.

For example, the second display module displays the device page corresponding to the navigation tag based on the user's first navigation command. The third display module displays M liquid oxygen tank tags on the device page. It allows users to view the target liquid oxygen tank by receiving user commands for any one of the M liquid oxygen tank tags. For example, the fourth display module displays the real-time monitoring video and current status parameters of the target liquid oxygen tank on the device page based on the user's first setting command. Then, the first judgment module determines the target liquid oxygen tank based on the current status parameters.

Furthermore, when a target liquid oxygen tank is experiencing an abnormality, the system adjusts the valve flow rate of the target liquid oxygen tank according to the user's second setting command. This facilitates the timely detection and handling of safety hazards, thereby addressing the problem of poor timeliness in existing liquid oxygen station monitoring methods.
