[0067] An inflatable bag capable of intelligently monitoring the pressure of the air valve, comprising an inflatable bag body 1, an air pipe 2 and an air column body 3, wherein the inflatable bag body 1 is provided with air pipes 2 at equal intervals on the surface, the top of the air pipe 2 is communicated with the inflation port 4 of the inflatable bag body 1, the bottom of the air pipe 2 is communicated with the air column body 3, the inside of the air pipe 2 is provided with a sealing structure 6, the lower part of the sealing structure 6 is provided with an air valve 9, the lower part of the air valve 9 is provided with a pressure monitoring instrument 5, one end of the inflatable bag body 1 is provided with a Velcro surface 7, the other end of the inflatable bag body 1 is provided with a Velcro surface 8, and the inflatable bag body 1 is adhered by using the Velcro surface 8 and the Velcro surface 7, which is simple to operate and convenient to use. The pressure is monitored in real time by using the pressure monitoring instrument 5, so as to avoid the rupture or insufficient inflation of the inflatable bag body 1 caused by overcharging or undercharging, thereby prolonging the service life.

[0068] The sealing structure 6 comprises a fixed plate 61, a movable plate 62, a hydraulic rod 63, a mounting piece 64 and a fixing piece 65, the mounting piece 64 is rotatably installed on the fixed plate 61, the hydraulic rod 63 is fixedly installed on the mounting piece 64, one end of the hydraulic rod 63 away from the mounting piece 64 is installed on the movable plate 62 through the fixing piece 65, the movable plate 62 is movably installed in the fixed plate 61, and the fixed plate 61 is fixedly installed on the inner wall of the air pipe 2.

[0069] In operation, the air column 3 is inflated through the air pump connected to the inflation port 4. At this time, the hydraulic rod 63 operates to retract the movable plate 62 into the fixed plate 61, open the sealing structure 6, and enable the gas to smoothly enter the air column 3. At the same time, the pressure monitor 5 operates to close the sealing structure 6 when the pressure in the air column 3 approaches the predicted pressure, so as to ensure that the pressure of the inflatable bag body 1 is always within the pressure threshold range, avoid the risk of explosion of the inflatable bag body 1 due to excessive pressure, and prevent the packaged product from being damaged during transportation.

[0070] The air valve 9 comprises an outer cylinder 91, an inner cylinder 92, a core cylinder 93, a spring 94, a sealing gasket 95, a limiting plate 96, and a plug rod 97. The inner cylinder 92 is sleeved in the outer cylinder 91, the core cylinder 93 is installed in the inner cylinder 92 in a threaded manner, the limiting plate 96 is arranged at the bottom of the core cylinder 93, the limiting plate 96 is provided with a through hole, the sealing gasket 95 is arranged on the side of the outer cylinder 91 facing the air column 3, the spring 94 is fixed on the sealing gasket 95, the plug rod 97 is fixed on the side of the sealing gasket 95 close to the outer cylinder 91, the plug rod 97 penetrates the insertion hole of the limiting plate 96, and the sealing gasket 95 moves in the axial direction of the air inlet direction of the core cylinder 93.

[0072] When the sealing gasket 95 is attached to the bottom of the core cylinder 93, the air valve 9 is in a sealed state. When the inflatable bag body 1 is inflated, the sealing gasket 95 is pushed away from the bottom of the core cylinder 93 under the action of air pressure to inflate the inside of the air column 3. When the inflation is completed, the sealing gasket 95 loses the pushing force and returns to the bottom of the core cylinder 93 under the action of the spring 94 to seal the air valve 9.

[0073] The pressure monitor 5 is provided with a control system, which comprises:

[0074] A data acquisition module is configured to acquire the effective area and inflation force of the inflatable bag body 1, calculate the standard pressure of the inflatable bag body 1 according to the effective area and inflation force of the inflatable bag body 1, and acquire the pressure data of the inflatable bag body 1.

[0075] A monitoring module is configured to monitor the pressure in the inflatable bag body 1 in real time and continuously collect the pressure data, and transmit the collected pressure data to a judgment module.

[0076] An analysis module is configured to determine whether the real-time monitored pressure data exceeds a preset pressure threshold and transmit the determination result to the control module.

[0077] The control module is configured to feedback adjust the pressure in the air cylinder 3 through the hydraulic rod 63 according to the air pressure data monitored by the monitoring module.

[0078] By monitoring the pressure of the inflatable bag body 1 in real time, the pressure condition of the inflatable bag body 1 during the inflation process can be understood, the gas inlet pressure of the air valve 9 can be adjusted according to the real-time pressure condition of the inflatable bag body 1, the risk of explosion of the inflatable bag body 1 caused by excessive pressure can be avoided, and the packaged product can be prevented from being damaged during transportation.

[0079] Preferably, the hydraulic rod 63 comprises:

[0080] A first control rod, one end of which is fixedly connected with the mounting member 64, the first control rod being hollow inside;

[0081] A second telescopic rod, one end of which is built in the first control rod and is in sliding connection with the other end of the first control rod;

[0082] A driving module, built in the second telescopic rod, for providing driving force for the movement of the hydraulic rod 63;

[0083] A control module, in communication connection with the driving module, the control module issuing instructions to control the movement of the driving module, the control module being in communication connection with the control system;

[0084] A first position distance sensor, built on the inner wall of the other end of the first control rod, for measuring the sliding distance of the second telescopic rod during the telescopic sliding movement of the second telescopic rod relative to the first control rod, the first position distance sensor being in communication connection with the control module;

[0085] A second laser distance sensor, built on the inner wall of the connecting end of the first control rod and the mounting member 64, for measuring the sliding distance of the second telescopic rod during the telescopic sliding movement of the second telescopic rod relative to the first control rod, the second laser distance sensor being in communication connection with the control module;

[0086] A calculation and analysis module, for receiving the first sliding distance detected by the first position distance sensor and the second sliding distance detected by the second laser distance sensor, calculating the arithmetic mean of the first sliding distance and the second sliding distance to obtain a calibrated sliding distance, and transmitting the calibrated sliding distance information to the control module;

[0087] The control module adjusts the driving movement of the driving module on the second telescopic rod in combination with the calibrated sliding distance.

[0088] The principle and effect of the above technical solution are that the hydraulic rod 63 is arranged as two parts of the first control rod and the second telescopic rod, and the second telescopic rod moves in sliding relative to the first control rod, so as to adjust the length of the whole hydraulic rod 63. When the whole length of the hydraulic rod 63 changes, the movable plate 62 is driven to move synchronously. Specifically, when the second telescopic rod is retracted relative to the first control rod, the second telescopic rod drives the movable plate 62 to retract into the fixed plate 61. When the movable plate 62 moves, the hydraulic rod 63 rotates along the mounting piece 64, so that the sealing structure 6 can be smoothly opened, and the gas can smoothly enter the gas column body 3. When the second telescopic rod is elongated relative to the first control rod, the second telescopic rod drives the movable plate 62 to extend from the lower end of the fixed plate 61, and gradually seals the sealing structure 6, so that the gas cannot enter the gas column body 3. The telescopic length of the second telescopic rod corresponds to the rotation angle of the movable plate 62. Combined with the length of the whole telescopic rod and the size of the movable plate 62 and the fixed plate 61, the two have a matching relationship. The driving module is used to provide driving force for the second telescopic rod, so as to drive the second telescopic rod to slide relative to the first control rod, thereby adjusting the length of the whole hydraulic rod 63. The driving module is controlled and started by the control module, so as to realize intelligent opening and closing without manual operation. The control module can accept the instruction of the control system, that is, when the control system judges that the sealing structure 6 needs to be opened or closed, the control module sends an instruction to start adjustment. The control module controls the movement of the driving module, so as to drive the second telescopic rod to slide relative to the first control rod. In this process, the opening or closing of the sealing structure 6 is realized. The sliding distance of the second telescopic rod directly affects the degree of adjustment, so the first position distance sensor and the second laser distance sensor simultaneously detect the sliding distance of the second telescopic rod. Two different types of distance sensors are mainly used to calibrate the error generated in the distance measuring process. The first sliding distance and the second sliding distance detected by the first position distance sensor and the second laser distance sensor are obtained respectively. The calibrated sliding distance can be matched with the rotation angle or rotation condition of the movable plate 62 relative to the fixed plate 61 by calculating the arithmetic mean. The matching relationship can be pre-stored in the control module. Therefore, the control module controls the driving of the second telescopic rod by the driving module, so as to realize the opening and closing of the sealing structure 6 and the adjustment of the opening size, thereby improving the inflation progress and inflation effect, and further realizing the adjustment of the pressure in the gas column body 3, which has high intelligence.

[0089] Specifically, the control system further comprises:

[0090] The pressure value real-time monitoring module is used to monitor the pressure in the inflatable bag body 1 in real time, and obtain the pressure change rate according to the pressure in the inflatable bag body 1 obtained by real-time monitoring.

[0091] a pressure change rate comparison module, configured to compare a pressure change rate in the inflatable bag body 1 with a preset pressure change rate threshold value;

[0092] a pressure change stability coefficient acquisition module, configured to, when the pressure change rate in the inflatable bag body 1 exceeds the preset pressure change rate threshold value, acquire a pressure change stability coefficient according to the pressure values collected each time and the current pressure change rate;

[0093] wherein the pressure change stability coefficient is acquired by the following formula:

[0094] wherein S represents the pressure change stability coefficient; m represents the total number of pressure collection in the inflatable bag body 1; R b represents the standard deviation of the pressure change rate corresponding to the m times of pressure collection in the inflatable bag body 1; R fmax represents the maximum value of the pressure change rate floating corresponding to the m times of pressure collection in the inflatable bag body 1; P b represents the standard deviation of the pressure value corresponding to the m times of pressure collection in the inflatable bag body 1; P fmax represents the maximum value of the pressure value floating corresponding to the m times of pressure collection in the inflatable bag body 1; R represents the pressure change rate in the inflatable bag body 1 when exceeding the preset pressure change rate threshold value; R y represents the preset pressure change rate threshold value, P i represents the pressure value corresponding to the i times of pressure collection in the inflatable bag body 1;

[0095] a data collection frequency adjustment module, configured to adjust the data collection frequency of the pressure in the inflatable bag body 1 by using the pressure change stability coefficient, to obtain an adjusted data collection frequency; wherein the adjusted data collection frequency is acquired by the following formula:

[0096] wherein F t represents the adjusted data collection frequency; F0 represents the data collection frequency before adjustment; S represents the pressure change stability coefficient; S y represents the preset pressure change stability coefficient reference value; R fmin represents the minimum value of the pressure change rate floating corresponding to the m times of pressure collection in the inflatable bag body 1; P fmax represents the maximum value of the pressure value floating corresponding to the m times of pressure collection in the inflatable bag body 1; P fmin represents the minimum value of the pressure value floating corresponding to the m times of pressure collection in the inflatable bag body 1; R b represents the standard deviation of the pressure change rate corresponding to the m times of pressure collection in the inflatable bag body 1;

[0097] a data acquisition control module for controlling the acquisition operation of the pressure value in the air bag body 1 according to the adjusted data acquisition frequency.

[0098] The technical effects of the above technical solution are: through the pressure value real-time monitoring module, the system can continuously and accurately monitor the pressure change in the air bag body 1 and instantly calculate the pressure change rate. This function provides real-time and reliable data basis for subsequent decision-making, ensuring that the system can respond to abnormal pressure changes in the first time. The pressure change rate comparison module compares the real-time monitored pressure change rate with the preset threshold, which can accurately judge whether the pressure state in the air bag body 1 is abnormal. This precise evaluation capability helps to avoid equipment damage or performance decline caused by excessive pressure fluctuation, thereby improving the stability and reliability of the system. When the pressure change rate exceeds the preset threshold, the system calculates the stability coefficient through the pressure change stability coefficient acquisition module. This index comprehensively reflects the stability and controllability of the pressure change in the air bag body 1 by considering multiple factors such as the standard deviation and maximum floating of the pressure change rate, the standard deviation and maximum floating of the pressure value, etc. This comprehensive evaluation method is more accurate than a single index in reflecting the actual situation, which helps the system make more reasonable decisions. The data acquisition frequency adjustment module dynamically adjusts the data acquisition frequency using the pressure change stability coefficient, realizing the intelligentization and self-adaptation of data acquisition. When the pressure change is stable, the acquisition frequency is reduced to reduce resource consumption; when the pressure change is severe, the acquisition frequency is increased to more accurately capture the pressure dynamics. This dynamic adjustment mechanism not only improves the efficiency of data acquisition, but also ensures the accuracy and integrity of the data. The data acquisition control module controls the acquisition operation of the pressure value in the air bag body 1 according to the adjusted data acquisition frequency, realizing accurate control of data acquisition. This control mechanism can ensure that the system runs efficiently while meeting the requirements of data acquisition accuracy and real-time performance in actual applications. In summary, this technical solution significantly improves the overall performance of the air bag body 1 pressure control system through real-time monitoring, precise evaluation, comprehensive index calculation, dynamic adjustment, and data acquisition control. It not only improves the stability and reliability of the system, but also reduces resource consumption, improves the efficiency and accuracy of data acquisition. These performance improvements are of great significance in improving product quality, prolonging equipment life, and reducing maintenance costs.

[0099] In summary, the application of this technical solution in the air bag body 1 pressure control system not only realizes real-time monitoring and precise evaluation of pressure changes, but also significantly improves the overall performance and reliability of the system through dynamic adjustment of data acquisition frequency and efficient data acquisition control.

[0107] The judgment module judges whether the pressure of the inflatable bag body 1 exceeds the pressure threshold value of the inflatable bag body 1 according to the comparison result.

[0108] The judgment process of the judgment module specifically comprises:

[0109] The pressure threshold value of the inflatable bag body 1 is set according to the calculated standard pressure of the inflatable bag body 1;

[0110] The next inflatable bag pressure prediction value is predicted according to the real-time collected inflatable bag body 1 pressure data value;

[0111] The pressure prediction value of the inflatable bag body 1 is compared with the pressure threshold value of the inflatable bag body 1;

[0112] The judgment module judges whether the pressure of the inflatable bag body 1 exceeds the pressure threshold value of the inflatable bag body 1 according to the comparison result.

[0113] The calculation formula of the standard pressure is as follows:

[0114] P=F / V

[0115] In the formula, P is the standard pressure, F is the inflation force, and V is the effective area of the inflatable bag body 1.

[0116] The working process of the control system specifically comprises:

[0117] The pressure threshold value of the inflatable bag body 1 is obtained, and the pressure threshold value is a continuous pressure data set with a time identifier;

[0118] Obtain the real-time pressure dataset of the inflatable bag body 1. The real-time pressure dataset is the real-time pressure change inside the inflatable bag body 1. The real-time pressure dataset and the pressure threshold have the same preset pressure and time identifier correspondence.

[0119] The differential pressure calculation module performs pressure difference calculation on the pressure threshold and real-time pressure dataset to obtain the pressure numerical difference.

[0120] The pressure inside the inflatable bag body 1 is determined based on the pressure difference. If it is within the pressure threshold range, there is no need to control the sealing structure 6 to work.

[0121] If the pressure threshold is approached, the sealing structure 6 is controlled to gradually reduce the opening until the pressure threshold is reached and then the sealing structure 6 is closed. By adjusting the inflation pressure, it is possible to better adapt to the packaging needs of various goods and ensure that the goods receive optimal cushioning and protection during transportation.

[0122] Working principle: When using the air bag of this invention that can intelligently monitor the pressure of the air valve, according to... Figures 1-8 This includes the following steps:

[0123] Step 1: Inflate the air column 3 by connecting the air pump to the air inlet 4. At this time, the hydraulic rod 63 works, retracting the movable plate 62 into the fixed plate 61 and opening the sealing structure 6, so that the gas can smoothly enter the air column 3.

[0124] Step 2: At this time, under the action of air pressure, the sealing gasket 95 is pushed away from the bottom of the outer cylinder 91, and the inside of the air column 3 is inflated.

[0125] Step 3: The pressure monitoring instrument 5 continuously monitors the pressure inside the gas column 3 and analyzes and judges the monitoring results;

[0126] Step 4: If the judgment result is that the pressure threshold of the inflatable bag body 1 is exceeded, the pressure regulation command of the inflatable bag body 1 is triggered, and the hydraulic rod 63 is controlled to work to pull the movable plate 62 out to the outside of the fixed plate 61, close the opening, and not inflate the air column 3.

[0127] Step 5: If the judgment result is that the pressure threshold of the inflatable bag body 1 is not exceeded, no response is made and the sealing structure 6 opens normally;

[0128] Step Six: If the judgment result is that the pressure of the inflatable bag body 1 is not exceeded and is close to the pressure threshold, then control the hydraulic rod 63 to work and pull the movable plate 62 out to the outside of the fixed plate 61 to reduce the opening until the pressure threshold is reached and then close the sealing structure 6, so that the pressure of the inflatable bag body 1 is always within the pressure threshold range. This can not only effectively reduce the wear of the inflatable bag body 1, but also avoid the rupture or insufficient inflation of the inflatable bag body 1 due to over-inflation or under-inflation, thereby extending its service life.

[0129] Step 7: After inflation is complete, the sealing gasket 95 loses its thrust and returns to the bottom of the outer cylinder 91 under the action of the spring 94, sealing the air valve 9.

[0130] In summary, the present invention provides an inflatable bag with intelligent valve pressure monitoring. By monitoring the pressure of the inflatable bag body 1 in real time, it can understand the pressure status of the inflatable bag body 1 during the inflation process. Based on the real-time pressure status of the inflatable bag body 1, it can adjust the gas inlet pressure of the valve 9. When the pressure inside the air column 3 is detected to be close to the predicted pressure, the sealing structure 6 is closed, ensuring that the pressure of the inflatable bag body 1 remains within the pressure threshold range. This not only effectively reduces the wear and tear on the inflatable bag body 1, preventing rupture or insufficient inflation due to over-inflation or under-inflation, thus extending its service life, but also, by adjusting the inflation pressure, it can better adapt to the packaging needs of various goods, ensuring optimal cushioning and protection for goods during transportation, and preventing the risk of explosion due to excessive pressure, which could damage the packaged products during transport.
