[0024] This utility model provides an automatic atmospheric data collection system 10 suitable for unattended environments. For example... Figure 1 and Figure 2As shown, the automatic atmospheric sampling system 10 of this embodiment generally includes a sampling gas cylinder assembly 100 and a gas sampling assembly 200. The sampling gas cylinder assembly 100 includes one or more sampling gas cylinders 110. The gas sampling assembly 200 includes an inlet 210, a gas pump 220, and a collection connector 230. The inlet 210 is used to receive gas from the monitored environment. The gas pump 220 is disposed on a pipeline between the inlet 210 and the collection connector 230, connected to the inlet 210, and is used to provide power for gas flow. The collection connector 230 is connected between the gas pump 220 and the sampling gas cylinder assembly 100, and is used to supply gas to the sampling gas cylinders 110. The automatic atmospheric sampling system 10, powered by the gas pump 220, achieves automatic gas flow from the inlet 210 to the collection connector 230 and then to the sampling gas cylinder assembly 100, eliminating the need for manual operation of the sampling process. This allows the automatic atmospheric data collection system 10 to avoid frequent on-site human intervention when used in remote areas, harsh environments, or scenarios requiring long-term continuous monitoring, thus saving labor costs and potential risks during operation.

[0025] In some optional embodiments, there are multiple sampling gas cylinders 110 arranged in the same direction. The automatic atmospheric sampling system 10 also includes a support frame 300 for fixing the multiple sampling gas cylinders 110. The support frame 300 includes a first support member 310 and a second support member 320. The first support member 310 is located near the inlet end 111 of the multiple sampling gas cylinders 110, and the second support member 320 is located near the outlet end 112 of the multiple sampling gas cylinders 110. The first and second support members 310 together fix the multiple sampling gas cylinders 110. The first and second support members 320 of the support frame 300 are fixed from both ends of the sampling gas cylinders 110, forming a relatively stable structure and avoiding tilting and shaking problems that may occur when a single support member only fixes one end. Especially in unattended outdoor environments, this effectively prevents the sampling gas cylinder assembly 100 from tipping over and the pipeline from falling off, ensuring the integrity of the sampling gas cylinder assembly 100 and its connecting pipelines.

[0026] Furthermore, the support frame 300 also supports the entire automatic atmospheric data collection system 10, enabling the automatic atmospheric data collection system 10 to be stably fixed in the operating environment.

[0027] It should be noted that "first support 310" and "second support 320" should be understood as the side closer to the inlet end 111 of the sampling gas cylinder 110 being the first support 310, and the side closer to the outlet end 112 of the sampling gas cylinder 110 being the second support 320. Furthermore, the support frame 300 consisting of the first support 310 and the second support 320 is merely an example; those skilled in the art can select different numbers of support members according to the actual usage environment to ensure the stability of the sampling gas cylinder assembly 100 in the automatic atmospheric sampling system 10.

[0028] The automatic atmospheric data collection system 10 may also include a main inlet valve 410 and multiple inlet valves 411. The main inlet valve 410 is located on the inlet pipe 420 between the gas pump 220 and the collection connector 230, near the inlet port 210, and is used to regulate the opening and closing state of the inlet pipe 420. As the main switch for the inlet pipe 420, it can uniformly control the opening and closing of the passage for collecting gases from the environment. For example, when the system is in standby, maintenance, or when collecting ambient gases is not required, closing the main inlet valve 410 can cut off the entry of external gases, preventing contamination of the pipes or calibration components by impurities. When forced cessation of data collection is required, the rapid closure of the main inlet valve 410 can more directly block gas flow than controlling the individual inlet valves 411, improving emergency response efficiency.

[0029] Each of the multiple inlet valves 411 is correspondingly set with an inlet end 111 of a sampling gas cylinder 110 and connected to a collection connector 230, thereby controlling the gas flow between the collection connector 230 and the corresponding sampling gas cylinder 110. This allows for independent control of each sampling gas cylinder 110's inlet end 111, achieving "one valve per cylinder." By switching different inlet valves 411 on and off, one or more sampling gas cylinders 110 can be flexibly selected for connection, meeting diverse needs for automatic atmospheric sampling.

[0030] The design of the main intake valve 410 and multiple intake valves 411 enables the automatic atmospheric data acquisition system 10 to achieve refined management. It comprehensively optimizes the system performance in terms of path flexibility, data accuracy, automation capabilities and ease of maintenance. In particular, it is suitable for the core requirements of automation, reliability and low intervention in unattended environments, and provides a more stable and controllable technical guarantee for automatic atmospheric data acquisition and calibration.

[0031] The automatic atmospheric data acquisition system 10 may also include an intake master valve support 430 and multiple intake valve supports 440 for supporting the intake master valve 410 and multiple intake valves 411. The intake master valve 410 and intake valves 411 are connected to components such as the gas pump 220 and sampling gas cylinder 110 via intake pipes 420. Without support, the weight of the valves themselves and the intake pipes 420 may cause the connection points to bear additional stress for a long time, which may easily lead to pipe loosening, interface deformation or sealing failure, and thus gas leakage. By fixing the installation positions of the main intake valve 410 and the multiple intake valves 411, the intake master valve support 430 and the multiple intake valves 440 can distribute the weight of the main intake valve 410 and the multiple intake valves 411 and the stress of the intake pipeline 420 to the support structure, reduce the mechanical load at the interface, reduce the risk of component aging or damage due to long-term stress, and extend the service life of the main intake valve 410, the multiple intake valves 411 and the intake pipeline 420.

[0032] The automatic atmospheric sampling system 10 may also include an exhaust assembly 500, which includes an exhaust pipe 510 and an exhaust port 520. The exhaust pipe 510 is connected to the outlet 112 of the sampling gas cylinder 110 to discharge the gas inside the cylinder. The exhaust port 520 is connected to the exhaust pipe 510 to discharge the gas discharged from the sampling gas cylinder 110 into the external environment. If the outlet 112 of the sampling gas cylinder 110 is closed, and the gas pump 220 continues to supply gas or the high-pressure gas inside the sampling gas cylinder 110 cannot be released, the pressure inside the pipe may rise abnormally, posing a risk of pipe rupture or port detachment. The exhaust assembly 500, as a pressure relief channel, can promptly discharge excess gas, maintain stable pressure inside the pipe, and protect core components such as the sampling gas cylinder 110, the main inlet valve 410, multiple inlet valves 411, and the gas pump 220 from high-pressure damage.

[0033] The automatic atmospheric sampling system 10 may also include a main exhaust valve 610 and multiple exhaust valves 611. The main exhaust valve 610 is located on the exhaust pipe 510 near the exhaust port 520 and is used to regulate the opening and closing state of the exhaust pipe 510. Each of the multiple exhaust valves 611 is correspondingly provided with an outlet end 112 of a sampling gas cylinder 110 and is connected to the exhaust pipe 510 to control the gas flow between the exhaust pipe 510 and the corresponding sampling gas cylinder 110.

[0034] Each exhaust valve 611 corresponds to the outlet 112 of a sampling gas cylinder 110, and can independently control the opening and closing of the exhaust passage of that sampling gas cylinder 110. For example, when the system is calibrating a particular sampling gas cylinder 110, the corresponding exhaust valve 611 can be opened, and the exhaust valves 611 of other sampling gas cylinders 110 can be closed, ensuring that only the gas from the currently used sampling gas cylinder 110 flows through the system and is discharged, preventing gas leakage or interference from other unused sampling gas cylinders 110. As another example, when a sampling gas cylinder 110 needs to be replaced, maintained, or is idle, its exhaust valve 611 can be closed to achieve physical isolation, preventing backflow of outside air or accidental discharge of residual gas from the cylinder.

[0035] The main exhaust valve 610 is located on the main path of the exhaust pipeline 510 near the exhaust port 520, and can centrally control the opening and closing of the entire exhaust pipeline 510. For example, when the entire system is shut down, under maintenance, or when exhaust is not required, closing the main exhaust valve 610 cuts off the exhaust path of all sampling gas cylinders 110, forming double protection and reducing the risk of gas leakage. Alternatively, when it is necessary to operate on the exhaust pipeline 510 itself, closing the main exhaust valve 610 can isolate the gas from all upstream sampling gas cylinders 110, ensuring operational safety.

[0036] The combined design of the main exhaust valve 610 and multiple exhaust valves 611 allows the independent exhaust valves 611 to support the parallel or time-sharing operation of multiple sampling gas cylinders 110, while the main exhaust valve 610 ensures unified management of the entire exhaust system. This design allows operators to flexibly adjust according to actual usage conditions, and can be compatible with more application scenarios without significant changes to the pipeline structure.

[0037] In some optional embodiments, the exhaust master valve 610 can be an electric ball valve, capable of controlled opening and closing, or controlled implementation of different degrees of opening. Operators can flexibly adjust the opening state according to real-time needs (such as pressure and flow changes) without manual intervention, thus improving the level of automation control. Correspondingly, the intake master valve 410 can also be an electric ball valve, which, in conjunction with the exhaust master valve 610, can greatly improve the level of automation control of the automatic atmospheric data acquisition system 10.

[0038] The automatic atmospheric data collection system 10 may also include an exhaust main valve support 620 and multiple exhaust valve supports 630 for fixing the exhaust main valve 610 and multiple exhaust valves 611.

[0039] Multiple exhaust valves 611 and the main exhaust valve 610 serve as key control nodes in the exhaust pipeline 510, enduring the gas pressure within the pipeline over extended periods. The main exhaust valve support 620 and multiple exhaust valve supports 630 are mechanically secured (e.g., by bolts or snap-fit ​​positioning) to prevent displacement, loosening, or pipeline interface detachment due to pressure fluctuations or equipment vibrations (e.g., resonance during gas pump 220 operation), thus mitigating the risk of gas leakage due to structural instability.

[0040] Multiple exhaust valve supports 630 can be spaced apart from the support frame 300. The exhaust main valve support 620 can be set with one side of the exhaust valve support 630 as support, or the setting method of the exhaust main valve support 620 can be adapted according to the specific setting position of the exhaust main valve 610.

[0041] Correspondingly, the arrangement of the intake master valve support 430 and the multiple intake valve supports 440 can refer to the arrangement of the exhaust master valve support 620 and the multiple exhaust valve supports 630. That is, the multiple intake valve supports 440 can be arranged at intervals with the support frame 300, and the intake master valve support 430 can be set with one side of the intake valve support 440 as support, or the arrangement of the intake master valve support 430 can be adapted according to the specific setting position of the intake master valve 410.

[0042] The automatic atmospheric data acquisition system 10 may also include multiple intake valve connectors 412, each corresponding to an intake valve 411, for connecting the intake valve 411 and the intake pipeline 420. Each intake valve 411 and intake valve connector 412 form an independent module. During installation, only the corresponding intake valve 411 needs to be connected to the intake valve connector 412, eliminating the need for complex pipeline branching designs. When a certain intake valve 411 or intake valve connector 412 malfunctions (such as seal failure or blockage), the module can be disassembled and replaced individually without shutting down the entire system, reducing maintenance downtime.

[0043] Furthermore, the automatic atmospheric data acquisition system 10 may also include multiple exhaust valve connectors 612, each exhaust valve connector corresponding to an exhaust valve 611, for connecting the exhaust valve 611 and the exhaust pipe 510. When a certain exhaust valve 611 or exhaust valve connector 612 malfunctions (such as seal failure or blockage), the module can be disassembled and replaced individually without shutting down the entire system, thus reducing maintenance downtime.

[0044] The automatic atmospheric data acquisition system 10 may also include a temperature sensor 710 and a pressure sensor 720. Both the temperature sensor 710 and the pressure sensor 720 are installed on the air inlet pipe 420 between the gas pump 220 and the collection connector 230, and are used to measure the temperature and pressure of the gas, respectively.

[0045] The temperature sensor 710 can monitor the temperature within the automatic atmospheric data acquisition system, which can then trigger protection mechanisms (such as pausing sampling or activating heating / cooling devices) to extend the equipment's lifespan.

[0046] By combining data from pressure sensor 720, the automatic atmospheric data acquisition system 10 can dynamically adjust the output power of gas pump 220. That is, it reduces the power when the pipeline pressure is stable and increases the power when the pressure is insufficient, thereby reducing ineffective energy consumption while ensuring sampling efficiency, which is especially suitable for long-term monitoring scenarios.

[0047] The automatic atmospheric data acquisition system 10 may also include a control unit 800, which is configured to collect gases from the monitored environment according to a pre-set time sequence and adjust the opening and closing status of the gas pump 220 based on data measured by the temperature sensor 710 and the pressure sensor 720. It can also adjust the inlet and outlet states of the sampling gas cylinder assembly 100 based on the measured data. The control unit 800 dynamically adjusts the main inlet valve 410, multiple inlet valves 411, the main exhaust valve 610, and multiple exhaust valves 611 using temperature and pressure data, thus obtaining relatively accurate calibration data.

[0048] The control unit 800 can also manage the clock of the automatic atmospheric data acquisition system 10, controlling the opening and closing of the main intake valve 410, multiple intake valves 411, the main exhaust valve 610, and multiple exhaust valves 611 via a bus, and adjusting the opening and closing status of each valve based on the collected pressure and temperature data. The control unit 800 can also be equipped with a start button, after which the automatic atmospheric data acquisition system 10 will have a delay of 4 to 12 hours to eliminate the impact of personnel construction and other factors on the on-site environment.

[0049] The control unit 800 can set parameters including the number A of sampling cylinders 110, the number of sampling times B for each sampling cylinder 110, and the sampling period C. It monitors data and outputs sampling commands, outputting one sampling command every time interval C. After outputting B sampling commands, the system proceeds to the next sampling cylinder 110. Once the number of sampling cylinders 110 is A, the system task is completed.

[0050] After receiving the collection command from the control unit 800, the sampling cylinder assembly 100, gas collection assembly 200, and exhaust assembly 500 collect samples from each cylinder one by one. At the start of each sampling cycle, the main inlet valve 410 and the main exhaust valve 610 are opened, along with the inlet valves 411 and 611 of the Nth and N+1th sampling cylinders 110, initiating a gas purging process. The duration of this process can be set according to actual needs. After the purging process is completed, the main exhaust valve 610, the exhaust valve 611 of the Nth sampling cylinder 110, and the inlet and exhaust valves 411 and 611 of the N+1th sampling cylinder 110 are closed, initiating the gas sampling and collection process. When the pressure of the automatic atmospheric collection system 10 reaches the set value, the main inlet valve 410 and the inlet valve 411 of the Nth sampling cylinder 110 are closed. Sampling ends, and the next sampling cycle begins.

[0051] The automatic atmospheric data acquisition system 10 may also include a mounting bracket for fixing the temperature sensor 710 and the pressure sensor 720. During operation, the automatic atmospheric data acquisition system 10 may vibrate, causing the connection between the temperature sensor 710 and the pressure sensor 720 and the intake pipe 420 to loosen, or causing the temperature sensor 710 and the pressure sensor 720 themselves to shake, both of which will affect the calibration results. The mounting bracket rigidly fixes the temperature sensor 710 and the pressure sensor 720 in a preset position, ensuring a tight connection with the intake pipe 420 and no displacement of the sensors themselves. This physically reduces the interference of external vibration or displacement on the measurement, ensuring the accuracy of the temperature and pressure data.

[0052] In some optional embodiments, the automatic atmospheric sampling system 10 may also include a thermal insulation system, which can be adjusted based on temperature data collected by the temperature sensor 710, thereby ensuring that the automatic atmospheric sampling system is always operating at a suitable temperature. The thermal insulation system, combined with the dynamic temperature control design of the temperature sensor 710, can stabilize the operating temperature of the equipment, eliminate the interference of temperature changes on gas sampling, and ensure that the automatic atmospheric sampling system 10 continuously outputs high-quality monitoring data in complex environments.
