[0022] like Figure 1 and Figure 2As shown, the present invention discloses an unattended industrial gas supply device based on cloud application, including a gas source 110, the gas source 110 is connected to a plurality of gas storage tanks 120 through a gas supply pipeline 100, the plurality of gas storage tanks 120 are connected to a gas terminal 200 through a gas supply pipeline and a bus 130, a check valve 140 is arranged between the gas source 110 and the gas storage tank 120, and elastic valves 150 are arranged at the gas outlets of the plurality of gas storage tanks 120, the elastic valve 150 can control the opening and closing of the gas outlet of the gas storage tank 120 according to the tank pressure in the gas storage tank 120, and a position sensor 151 for monitoring the opening and closing of the elastic valve 150 is also arranged in the elastic valve 150; the check valve 140 at the gas outlet end of the bus 130 is arranged at the check valve 140, and the check valve 140 at the gas outlet end of the bus 130 is arranged at the check valve 140; the check valve 140 at the check valve 140 at the check valve 140 The proportional pressure control valve 160 is connected to the gas supply pipeline 100; it also includes a pressure transmitter 170, which is arranged on the gas supply pipeline 100 between the proportional pressure control valve 160 and the gas terminal 200, and is used to monitor the gas pressure in the gas supply pipeline 100; it also includes a purification device 180, which is arranged on the gas supply pipeline, and the purification device 180 includes two purifiers 181 arranged in parallel, and the gas inlet ends of the two purifiers are both provided with gas inlet valves, and the gas outlet ends of the two purifiers are both provided with gas outlet valves. The purification device 180 can remove impurity gases and particulates that may remain in the gas, further improve the purity of the gas, and meet the different purity requirements of customers for the gas. In the actual use process, technicians in this field can use different regeneration processes such as replacement regeneration or compound regeneration for the two side-by-side purifiers according to the specific requirements for the gas.

[0023] The cloud processing platform 300 is also included. The cloud processing platform 300 includes a receiving module 310, a storage module 320, an analysis module 330, a processing module 340 and a transmission module 350. The receiving module 310 is used to receive instructions and signals transmitted by the transmission module 350, and transmit the instructions and signals to the analysis module 330. After analyzing the instructions and signals, the analysis module 330 sends the operation command to the processing module 340. The processing module 340 controls the corresponding terminal to make instructions through the transmission module 350; the storage module 320 is pre-set with a pressure threshold of the pressure transmitter 170, the pressure transmitter 170 and the position sensor 151 are connected to the receiving module 310 through the transmission module 350, and the proportional pressure control valve 160 and the check valve 140 are connected to the processing module 340 through the transmission module 350, wherein the transmission module 350 includes wireless communication based on ZigBee and wireless communication modes based on 3G / 4G / 5G, and the receiving module 310 is a 433M wireless receiving module.

[0024] In this solution, industrial gas first enters the gas tank 120 from the gas source 110 through the gas supply pipeline for storage and preliminary buffering. When the gas pressure value in the gas tank 120 is large, it means that a considerable amount of industrial gas has been stored in the gas tank 120. At this time, the elastic valve 150 is opened, and the gas in the gas tank 120 reaches the gas terminal via the bus 130 and the proportional pressure control valve 160. The pressure transmitter 170 set at the proportional pressure control valve 160 obtains the industrial gas pressure value in the gas supply pipeline 100 at the location, and converts this physical quantity into an analog quantity of 4~20mA, and transmits this analog quantity to the cloud processing platform 300 through the transmission module 350. The receiving module 310 of the cloud processing platform 300 transmits the received analog quantity to the analysis module 330. The analysis module 330 determines whether the received pressure value meets the requirements according to the pressure threshold of the pressure transmitter 170 pre-set in the storage module 320. The analysis module 330 makes a judgment on the data analysis result and feeds back the final instruction to the processing module 340. At this time, if the collected pressure value is not within the preset pressure threshold range, the processing module 340 controls the opening amplitude of the proportional pressure control valve 160 through the transmission module 350, so that the industrial gas pressure supplied to the gas terminal 200 meets the requirements. In this case, automatic monitoring and adjustment of the gas pressure flowing to the gas terminal 200 can be achieved, and intelligent gas supply in the gas supply pipeline can be achieved without using manpower.

[0025] In addition, the cloud processing platform 300 in the present solution is also electrically connected to the position sensor 151 provided in the elastic valve 150. The position sensor 151 is used to monitor the opening and closing of the elastic valve 150. When the analysis module 330 analyzes that the elastic valve 150 is closed, that is, at this time, the gas in the gas tank 120 no longer flows to the bus 130 due to the low pressure, indicating that the amount of industrial gas in the gas tank 120 is already small at this time. At this time, the processing module 340 opens the check valve 140 through the transmission module 350, and the gas source 110 inflates the gas tank 120. When the gas pressure in the gas tank 120 is large enough, the elastic valve 150 opens again to enter the next gas supply cycle.

[0026] From the above, it can be seen that the control method of this scheme can realize continuous and automatic gas supply in the pipeline without manual intervention, saving labor costs, and the gas supply pressure is stable. It can perform intelligent gas supply according to the pre-set gas supply pipeline pressure value, with a high degree of automation.

[0027] like Figures 3 to 5As shown, the setting of the elastic valve 150 can be realized as long as it can realize the opening and closing of the gas supply pipeline at the gas outlet of the gas tank 120 according to the gas pressure in the gas tank 120. In actual use, it is generally achieved by a pressure sensor set in the gas tank 120 and a solenoid valve set in the gas supply pipeline at the gas outlet of the gas tank. In the present embodiment, the elastic valve 150 includes a transverse base 152 and a longitudinal base 153, in which a transverse pipe 154 and a longitudinal pipe 155 are respectively provided, the transverse pipe 154 is connected to the gas supply pipe 100 at the gas outlet of the gas storage tank 120, and the longitudinal pipe 155 is connected to the gas supply pipe 100 at the gas inlet of the bus 130, and a piston plate 156 is arranged in the transverse pipe 154, and the piston plate 156 is clamped in the transverse pipe 154 by an elastic element, and the piston plate 156 moves along the transverse pipe 154 according to the change of the gas pressure in the transverse pipe, thereby realizing the connection and blocking of the transverse pipe 154 and the longitudinal pipe 155.

[0028] In this solution, the elastic element drives the piston plate 156 to move in the transverse pipe 154 when the gas pressure in the transverse pipe 154 changes. When the gas pressure in the transverse pipe 154 is relatively high, the piston plate moves toward the side away from the gas tank 120, and the transverse pipe 154 is connected to the longitudinal pipe 155. At this time, the gas in the gas tank 120 flows to the bus bar. When the gas pressure value in the gas tank 120 is relatively low, the gas pressure value in the transverse pipe is also relatively low. At this time, the elastic element drives the piston plate 156 to move toward the side where the gas tank 120 is located until the connection between the transverse pipe 154 and the longitudinal pipe 155 is blocked, and the gas tank 120 stops supplying gas to the bus bar 130. In this solution, the position sensor 151 can be set on the piston plate 156 to monitor the opening and closing of the elastic valve 150, and then the gas tank 120 corresponding to the elastic valve 150 can be inflated when the elastic valve 150 is closed.

[0029] The opening and closing of the elastic valve 150 is realized only according to the influence of the gas pressure in the corresponding gas storage tank 120 on the position of the piston plate 156. This control method abandons the traditional pressure sensor and solenoid valve combined control method, and can be realized by using only traditional mechanical parts through clever design. Under the condition of meeting the needs, the control of the opening and closing of the elastic valve 150 is safer and more reliable. As one of the preferred methods, the elastic valve 150 also includes a fixed disk 157, which is fixedly arranged in the transverse pipe 154. The fixed disk 157 is connected to the piston plate 156 through a reset spring 158. The piston plate 156 is fixedly connected to a guide rod 159 on the side facing the fixed disk 157. A guide rod through hole 1571 is provided at the corresponding position of the fixed disk 157, and a plurality of vents 1572 are also provided on the fixed disk 157. When the gas pressure in the transverse pipe 154 is relatively high, the gas passing through the vent hole 1572 pushes the piston plate 156 to move toward the side away from one end of the gas tank. At this time, the transverse pipe 154 and the longitudinal pipe 155 are connected, and the piston plate 156 continues to move until it moves to the inner wall of the elastic valve. At this time, the gas in the gas tank 120 continues to flow into the bus 130. When the gas in the gas tank 120 is less, the reset spring 158 gradually shrinks and resets. When the pressure value in the transverse pipe 154 is small enough, the piston plate 156 gradually blocks the transverse pipe 154 and the longitudinal pipe 155, and the gas tank 120 stops supplying gas to the bus 130. The cooperation between the guide rod 159 and the guide rod through hole 1571 can ensure that the piston plate 156 will not be twisted or offset during the movement, thereby ensuring the sealing effect of the piston plate 156.

[0030] In addition, the gas supply device also includes an audible and visual alarm device 400, which is electrically connected to the processing module 340. The audible and visual alarm device 400 can alarm when the pressure in the gas supply pipeline 100 monitored by the pressure transmitter 170 is continuously lower than the pressure threshold value preset in the storage module 320. Under normal circumstances, when the analysis module 330 analyzes that the pressure value in the gas supply pipeline 100 monitored by the pressure transmitter 170 is lower than the preset pressure threshold value, the opening amplitude of the proportional pressure control valve 160 is controlled by the processing module 340 and the transmission module 350 to increase the gas output of the bus 130. However, if the analysis module 330 analyzes that the pressure in the gas supply pipeline 100 is continuously lower than the pressure threshold value preset in the storage module 320, it means that other conditions other than the monitorable conditions have appeared in the front-end gas supply system before the bus 130, and manual intervention is required at this time. The audible and visual alarm device 400 can remind nearby staff to check and troubleshoot. It is worth noting that the time within which the pressure value in the gas supply pipeline 100 is lower than the pressure threshold preset in the storage module 320 before the sound and light alarm device 400 is activated can be preset according to the actual work demand for industrial gas. Those skilled in the art can make reasonable presets based on actual conditions, so it is not elaborated in this application document.

[0031] In addition, in order to avoid the situation in the above scheme where there are no workers near the gas supply device or the noise in the workplace is too loud, causing the workers to fail to promptly notice that the sound and light alarm device 400 is turned on, in this scheme, the gas supply device includes a mobile terminal 500, and the mobile terminal 500 obtains the monitoring and analysis data of the cloud processing platform through the transmission module 350, thereby realizing remote monitoring of the gas supply device, further improving the intelligence and safety of the gas supply device in this application document.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
