[0046] The inventors found in their research that special gases are needed in many technical fields. The meaning of special gases can be simply understood as non-air, toxic, harmful, and dangerous gases that are only used for special purposes. In the process of using special gases, gas cylinders are generally used to store special gases. Automatic gas filling devices can be used for filling special gases, but the automatic gas filling system and the front-end and back-end equipment of the automatic gas filling system usually rely on manual operation and decentralized monitoring, which has the following problems: manual monitoring has a slow response speed and is difficult to achieve real-time dynamic adjustment, resulting in low efficiency; if the front-end and back-end equipment fail during the filling process, it may cause gas leakage, pipeline bursting or even explosion. For some special gases, escaping into the air will also cause harm to the environment and operators; the front-end and back-end equipment and the filling device operate independently, lack unified monitoring and linkage control, and fault handling is delayed; at the same time, some equipment is in the startup state for a long time, which increases energy consumption and reduces equipment life.

[0047] Therefore, how to improve the above problems has become one of the technical problems that need to be solved urgently at this stage.

[0048] In view of this, the present disclosure provides a monitoring system and a monitoring method for an automatic gas filling device, at least to improve the above-mentioned problem.

[0050] It should be noted that the present disclosure provides a monitoring system 100 for an automatic gas filling device 10, which is used to monitor the front-end and rear-end equipment of the automatic gas filling device 10. When an abnormality occurs in the front-end and rear-end equipment of the automatic gas filling device 10, the working status of the automatic gas filling device 10 and its front-end and rear-end equipment is adjusted in time.

[0051] Specifically, the front and rear end equipment of the automatic gas filling device 10 includes a filling front end device 20 and a filling rear end device 30.

[0052] The monitoring system 100 is provided with a monitoring device 40, which monitors the working status of the filling front-end equipment 20, the filling back-end equipment 30 and the automatic gas filling device 10, and makes timely adjustments to the relevant equipment. In some optional embodiments, the monitoring device 40 monitors the working status of the filling front-end equipment 20, and when an abnormality occurs in the filling front-end equipment 20, the filling front-end equipment 20 and the automatic gas filling device 10 are stopped in time.

[0053] The monitoring system 100 of the automatic gas filling device 10 provided by the present disclosure monitors the front-end and rear-end equipment by setting a monitoring device 40. When the front-end and rear-end equipment are abnormal, the working status of the front-end and rear-end equipment and the automatic gas filling device 10 is adjusted in time. Such a setting is conducive to timely response to the abnormal state of the equipment, thereby realizing dynamic adjustment, which is conducive to improving the working efficiency of the entire system; for some special gases (special gases can be toxic, harmful, and dangerous gases), if the front-end and rear-end equipment are abnormal, the monitoring system 100 can timely control the relevant equipment to stop working, which is conducive to preventing damage to the environment and operators caused by problems such as gas leakage and pipeline burst, and improving the safety of the automatic gas filling process; and, the present disclosure is conducive to improving the degree of automation of the automatic gas filling process by linking the automatic gas filling device 10 and its front-end and rear-end equipment; at the same time, the start and stop of the corresponding equipment can be controlled according to the status of different equipment, which is conducive to preventing the equipment from being in the startup state for a long time, thereby also helping to reduce energy consumption and increase the life of the equipment.

[0054] Figure 2The figure shows a schematic diagram of the automatic gas filling device provided by the embodiment of the present disclosure. Figure 1 and Figure 2 In an optional embodiment of the present disclosure, the automatic gas filling device 10 includes a filling pipe 102 and a gas cylinder 105, and the automatic gas filling device 10 is used to fill the target gas into the gas cylinder 105; the filling front-end equipment 20 includes a compression device, and the filling back-end equipment 30 includes a vacuum pump; the compression device is used to pressurize the target gas, and the vacuum pump is used to extract the gas in the filling pipe.

[0055] Specifically, in the automatic gas filling device 10, the target gas is transported through the filling pipe 102 and then filled into the gas cylinder 105. It should be noted that this disclosure only illustrates some components of the automatic gas filling device 10 and does not represent the actual structure of the automatic gas filling device 10, nor is it limited to this.

[0056] The front end of the automatic gas filling device 10 includes a compression device, which is used to compress the low-pressure gas in the gas source to the high pressure required for filling, so that it can be smoothly filled into the gas cylinder. It can be seen that the compression device is an important equipment for gas filling. The present disclosure monitors the operating status of the compression device through the monitoring device 40, which is conducive to ensuring the smooth progress of gas filling. Optionally, the compression device can be a compressor, and further, the compression device can be a diaphragm compressor. It should be noted that the present disclosure is only described by this example and is not limited to this.

[0057] The rear end of the automatic gas filling device 10 includes a vacuum pump, which is used to extract the gas in the filling pipe 102, thereby purifying the gas in the filling pipe 102. The present disclosure provides an optional embodiment in which the process of purifying the filling pipe 102 includes: the vacuum pump extracts the gas in the filling pipe 102, and the purge gas input device inputs purge gas into the filling pipe 102, wherein the vacuum pump extracts the gas in the filling pipe 102 and the purge gas input device inputs purge gas into the filling pipe 102 alternately, thereby gradually replacing the gas in the filling pipe 102 to achieve the purpose of purification. The provision of the vacuum pump is conducive to purifying the filling pipe 102, thereby helping to reduce the contamination of the target gas during the filling process.

[0058] In this embodiment, the coordinated operation of the front-end compression device and the rear-end vacuum pump is conducive to ensuring the purity and filling speed of the filling gas. The present disclosure monitors the front-end compression device and the rear-end vacuum pump, which is conducive to ensuring the normal operation of the compression device and the vacuum pump. When abnormalities occur in the compression device and the vacuum pump, corresponding measures are taken in time, which is conducive to improving the filling efficiency and safety.

[0059] Please continue to refer to Figure 1 and Figure 2 In an optional embodiment of the present disclosure, the monitoring device 40 further includes a control component; the control component is connected to the compression device and the vacuum pump, and the control component is at least configured to control the start and stop of the compression device and / or the vacuum pump.

[0060] Specifically, the present disclosure monitors the working status of the compression device and the vacuum pump through the monitoring device 40. When the working status of the compression device and the vacuum pump is abnormal, a timely response is required. Therefore, the present disclosure sets a control component to control the start and stop of the compression device and the vacuum pump, which is conducive to accurately controlling the start and stop of the equipment, avoiding filling failure caused by overpressure or underpressure and problems such as substandard purity of the filling gas.

[0061] Please continue to refer to Figure 1 and Figure 2 In an optional embodiment of the present disclosure, the automatic gas filling device 10 also includes a control cabinet and an instrument gas source component 101, the instrument gas source component 101 is electrically connected to the control cabinet, and the control cabinet is used to control the instrument gas source component 101 to output the target gas; the control component includes an on-site control box and a remote control module; the on-site control box is located at the gas filling site, and is used to control the start and stop of the compression device and / or the vacuum pump through a touch device; the remote control module is integrated in the control cabinet of the automatic gas filling device 10, and is used to control the start and stop of the compression device and / or the vacuum pump through a programmable logic controller.

[0062] It should be noted that the control cabinet represents a functional device capable of issuing control commands on its own or for an operator to issue control commands. The instrument air source assembly 101 represents a functional device capable of outputting a target gas. Optionally, a filling pipe 102 connects the instrument air source assembly 101 and a gas cylinder 105 , allowing the target gas to flow from the instrument air source assembly 101 through the filling pipe 102 into the gas cylinder 105 .

[0063] Specifically, the present disclosure implements start / stop control of the compression device and vacuum pump by providing a control assembly. In this embodiment, the control assembly includes an on-site control box and a remote control module. Optionally, the on-site control box is equipped with a touchscreen to control the start / stop of the compression device and / or vacuum pump. Exemplarily, the touchscreen can be a touch screen. This facilitates enhanced automation and visualization of on-site control. Optionally, the on-site control box is also equipped with an emergency stop button or switch and a status indicator light to support local manual operation, allowing operators to promptly address abnormalities in the compression device and vacuum pump. Optionally, the on-site control box can be equipped with separate control boxes for the compression device and vacuum pump, i.e., each control box corresponds to a specific on-site control box. Alternatively, the control boxes for the compression device and vacuum pump can be integrated, i.e., a single control box can control both the compression device and the vacuum pump. This choice is subject to practical application and is not specifically limited in this disclosure. It should be noted that the on-site control box can control the start / stop switch via an AC contactor. This disclosure is merely illustrative of this example and is not intended to be limiting.

[0064] The control component also includes a remote control module, which is integrated into the control cabinet of the automatic gas filling device 10 to achieve remote control of the compression device and the vacuum pump. It should be noted that the remote control module can be implemented through analog or digital control, and the present disclosure is only described as an example and is not limited to this. The present disclosure provides an optional implementation method, that is, when the on-site operators fail to find the abnormal status of the front-end and back-end equipment in time, the remote control module can remotely stop the operation of the compression device, the vacuum pump and the automatic gas filling device 10, which is conducive to timely handling of abnormal situations and improving the safety and automation of the gas filling process. The present disclosure provides another optional implementation method, that is, after the gas filling is completed, the remote control module is set to turn on the vacuum pump, fill the filling pipe with nitrogen m times, evacuate n times, cycle p times, and turn off the vacuum pump, wherein m, n, and p are all positive integers, and the specific values ​​can be set according to needs, and the present disclosure does not make specific limitations.

[0065] The present disclosure realizes the control requirements of different scenarios by setting up an on-site control box and a remote control module, which is further beneficial to improving the safety and automation of gas filling.

[0066] Please refer to Figure 1 In an optional embodiment of the present disclosure, the compression device includes a first abnormality detection component, which is connected to the monitoring device 40; the first abnormality detection component is used to monitor the operating status of the compression device. When the operating status of the compression device is abnormal, the first abnormality detection component alarms and sends an alarm message to the monitoring device 40.

[0067] Specifically, to further achieve accurate monitoring of the compression device, the present disclosure provides a first abnormality detection component for monitoring the operating status of the compression device. For example, the first abnormality detection component detects whether the outlet pressure of the compression device is normal. When the compression device is a diaphragm compressor, the first abnormality detection component detects the wear of the diaphragm of the compression device. The specific setting can be based on the actual parameters to be detected, and the present disclosure does not specifically limit it. When the first abnormality detection component detects that the state of the compression device is abnormal, it executes an alarm and sends an alarm message to the monitoring device 40. The monitoring device 40 promptly shuts down the compression device and the automatic gas filling device 10, which is conducive to ensuring the smooth filling of the gas.

[0068] Please continue to refer to Figure 1 In an optional embodiment of the present disclosure, the vacuum pump includes a second abnormality detection component, which is connected to the monitoring device 40; the second abnormality detection component is used to monitor the operating status of the vacuum pump. When the operating status of the vacuum pump is abnormal, the second abnormality detection component alarms and sends an alarm message to the monitoring device 40.

[0069] Specifically, in order to achieve control of the vacuum pump, a second abnormality detection component is set, and the status of the vacuum pump is detected by the second abnormality detection component. For example, the second abnormality detection component is used to detect whether the pressure switch of the vacuum pump is normal. When an abnormality occurs, an alarm operation is performed and an alarm message is sent to the monitoring device 40. The monitoring device 40 shuts down the vacuum pump and the automatic gas filling device 10 in time, which is conducive to ensuring the cleanliness of the filling pipeline and the purity of the filling gas.

[0070] Please continue to refer to Figure 1 In an optional embodiment of the present disclosure, the vacuum pump includes a temperature sensor, which is used to monitor temperature data inside the vacuum pump.

[0071] Specifically, the temperature of the vacuum pump will increase during operation. This embodiment sets a temperature sensor to detect the temperature of the vacuum pump. When the temperature of the vacuum pump reaches the set value (for example, greater than or equal to 85°C), the vacuum pump is controlled to shut down, and the shutdown signal is transmitted to the monitoring device 40, thereby controlling the automatic gas filling device 10 to shut down urgently. This is beneficial to prevent poor vacuuming effect or vacuum pump abnormality due to excessively high vacuum pump temperature, and is beneficial to improving the safety of the gas filling process and the cleanliness of the filling pipeline.

[0072] Based on the same inventive concept, the present disclosure provides a monitoring method for an automatic gas filling device. Figure 3 FIG2 is a schematic diagram of a monitoring method for a gas automatic filling device provided by an embodiment of the present disclosure, please refer to FIG2. Figure 1 and Figure 3 , monitoring methods include:

[0073] Step S10: Acquire the operating status of the filling front-end device 20 and the filling back-end device 30; wherein the filling front-end device 20 is located at the front end of the automatic gas filling device 10, and the filling back-end device 30 is located at the back end of the automatic gas filling device 10;

[0074] Step S20: When the operating status of the filling front-end equipment 20 and / or the filling back-end equipment 30 is abnormal, the automatic gas filling device 10 is controlled to stop filling, and the filling front-end equipment 20 and / or the filling back-end equipment 30 are controlled to shut down.

[0075] It should be noted that the present disclosure provides a monitoring method for an automatic gas filling device, including but not limited to steps S10 to S20.

[0076] Specifically, the monitoring method provided by the present disclosure monitors the operating status of the filling front-end equipment 20 and / or the filling back-end equipment 30. When it is found that the operating status of one of the filling front-end equipment 20 and the filling back-end equipment 30 is abnormal, the filling is stopped in time, and the filling front-end equipment 20 and / or the filling back-end equipment 30 are controlled to shut down. Specifically, when the filling front-end equipment 20 is found to be abnormal, the operation of the filling front-end equipment 20 and the automatic gas filling device 10 is stopped; when the filling back-end equipment 30 is found to be abnormal, the operation of the filling back-end equipment 30 and the automatic gas filling device 10 is stopped; when the filling front-end equipment 20 and the filling back-end equipment 30 are both found to be abnormal, the operation of the filling front-end equipment 20, the filling back-end equipment 30 and the automatic gas filling device 10 is stopped. Such a setting is conducive to timely knowing the operating status of the front-end and rear-end equipment of the automatic gas filling device 10, and timely handling of abnormal situations. On the one hand, it improves the degree of automation of the gas filling process. On the other hand, when the target gas to be filled is a special gas, it is conducive to preventing the special gas from escaping into the air and causing harm to the environment or operators, thereby improving the safety of the filling process.

[0077] Please continue to refer to Figure 1 and Figure 3 In an optional embodiment of the present disclosure, the monitoring method further includes: when the operating status of the filling front-end device 20 is abnormal, the filling front-end device 20 executes an alarm; and / or, when the operating status of the filling back-end device 30 is abnormal, the filling back-end device 30 executes an alarm.

[0078] Specifically, this embodiment is configured such that when the operating status of the filling front-end equipment 20 and / or the filling back-end equipment 30 is abnormal, the relevant equipment performs an alarm operation. Such a configuration is beneficial for the operator or the monitoring system 100 to promptly know the abnormal status of the front-end and back-end equipment of the automatic gas filling device 10, so as to make relevant adjustments in a timely manner, which is further beneficial to improving the safety and timeliness of the filling process.

[0079] Please continue to refer to Figure 1 and Figure 3 In an optional embodiment of the present disclosure, the monitoring method further includes: monitoring the temperature data of the filling back-end equipment 30, and when the temperature data is abnormal, controlling the filling back-end equipment 30 and the automatic gas filling device 10 to stop filling.

[0080] Specifically, optionally, the filling back-end equipment 30 includes a vacuum pump. The temperature of the vacuum pump will increase during operation. When the temperature is too high, the safety of the equipment will be reduced. Therefore, the present disclosure monitors the temperature data of the filling back-end equipment 30. When the temperature data exceeds the threshold range, the filling back-end equipment 30 and the gas automatic filling device 10 are stopped in time, which is conducive to improving the safety of the filling process.
