Description

Technical Field

[0001] The present invention relates to the technical field of sensor monitoring devices, and in particular to a real-time safety monitoring device and method based on multi-sensor fusion. Background Art

[0002] Real-time security monitoring based on multi-sensor fusion is a technology that integrates data from multiple sensors and uses advanced algorithms and computing platforms to achieve real-time, high-reliability security status assessment of the target environment or system.

[0003] Food and beverage fermentation tanks need to be installed with various sensors to monitor various parameters inside the tanks. However, in the existing technology, most sensors are installed by adding flange pipes to the outside of the tank body and then bolting the sensors to the flange pipes. Connecting the flange pipes to the sensors with bolts requires turning multiple bolts, which is cumbersome and slow to disassemble and assemble. In addition, the monitoring data requires manual supervision. Therefore, a real-time safety monitoring device and method based on multi-sensor fusion is proposed to solve the above problems. Summary of the Invention

[0004] (1) Technical problems solved In response to the shortcomings of the existing technology, the present invention provides a real-time safety monitoring device and method based on multi-sensor fusion, which has the advantages of quick disassembly and assembly, multi-level alarm, etc., and solves the problem that connecting the flange pipe to the sensor with bolts requires turning multiple bolts, which is cumbersome, disassembly and assembly is slow, and monitoring data requires manual monitoring.

[0005] (2) Technical solution The technical solution of the present invention to solve the above technical problems is as follows: a real-time safety monitoring device based on multi-sensor fusion, comprising a tank flange tube, a columnar probe, a fluorescence lifetime sensor, a temperature sensor and an infrared absorption sensor, the columnar probe being adapted to the tank flange tube, an assembly column being fixedly connected on the right side of the columnar probe, an adjustment component extending to its right side being provided inside the assembly column, a transmission disk being transmission-connected to the adjustment component and located inside the assembly column being provided on the outside of the assembly column, return hooks being distributed in an annular array and extending to the outside of the assembly column being provided inside the assembly column, the return hooks being transmission-connected to the transmission disk and adapted to the tank flange tube, elastic reset components extending to the right wall of the inner cavity of the assembly column being provided on opposite sides of the return hooks located inside the assembly column, a fluorescence lifetime sensor, a temperature sensor and an infrared absorption sensor being embedded in the right end of the columnar probe, a protective cover being fixedly connected on the right side of the assembly column, an analysis and processing component being electrically connected to the fluorescence lifetime sensor, the temperature sensor and the infrared absorption sensor being provided inside the protective cover.

[0006] The beneficial effects of the present invention are: 1) The real-time safety monitoring device based on multi-sensor fusion places a columnar probe into the tank flange tube so that the return hook is located on the peripheral side of the flange at the right end of the tank flange tube. The adjustment component is driven to rotate by an electric wrench. Since the adjustment component is connected to the transmission disk, the transmission disk is driven to move. The transmission disk drives the return hook to move to the opposite side and compresses the elastic reset component at the same time. Since the return hook is adapted to the tank flange tube, when the return hook contacts the flange at the right end of the tank flange tube, it drives the left side of the assembly column to approach the tank flange tube until it is tightly fitted, completing the installation of the device, which has the advantage of quick disassembly and assembly.

[0007] 2) This real-time safety monitoring method based on multi-sensor fusion installs a columnar probe in the tank flange tube. The fluorescence lifetime sensor, temperature sensor and infrared absorption sensor embedded at the left end of the columnar probe monitor the dissolved oxygen, temperature and carbon dioxide concentration in the tank flange tube in real time. The analysis and processing component analyzes and processes the data it obtains, and then makes corresponding alarm processing step by step according to the changes in dissolved oxygen, temperature and carbon dioxide concentration, which has the advantage of multi-level alarm.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the adjustment assembly includes a hexagonal screw and a sliding rod. The left wall of the inner cavity of the assembly column is rotatably connected to the hexagonal screw extending to its right side. The sliding rods are fixedly connected between the left and right walls of the inner cavity of the assembly column and are symmetrically distributed up and down. The outer side of the hexagonal screw is threadedly connected to a transmission plate that is slidably connected to the sliding rod.

[0010] The beneficial effect of adopting the above-mentioned further scheme is that the hexagonal screw is driven to rotate by the electric wrench. Since the hexagonal screw is threadedly connected to the transmission plate, and the transmission plate is slidingly connected to the slide rod, the force generated by the rotation of the outer thread of the hexagonal screw then drives the transmission plate to slide on the outside of the slide rod.

[0011] Furthermore, a truncated cone-shaped countersunk hole is opened on the right side of the transmission disc, and one end of the loop hook located inside the assembly column is adapted to the truncated cone-shaped countersunk hole on the right side of the transmission disc; Furthermore, one end of the loop hook located outside the assembly column is adapted to the tank flange pipe.

[0012] The beneficial effect of adopting the above-mentioned further scheme is that when the transmission disc moves toward the end of the return hook located inside the assembly column, the side wall of the frustum-shaped countersunk hole on the right side of the transmission disc contacts the return hook, forcing the return hook to move to the opposite side. At the same time, the return hook contacts the flange at the right end of the tank flange tube, and then drives the left side of the assembly column to approach the tank flange tube until it is tightly fitted.

[0013] Furthermore, the elastic reset assembly includes a stop rod and a reset spring, and the opposite side of the return hook located inside the assembly column is fixedly connected to the stop rod extending to the inside of the right wall of the inner cavity of the assembly column, and the opposite end of the stop rod is provided with a reset spring located inside the right wall of the inner cavity of the assembly column.

[0014] The beneficial effect of adopting the above further solution is that the return hook moves to the opposite side, and at the same time the return spring is squeezed by the stop rod, and the return spring elastically contracts, so that the hexagon socket head screw can be reversed later to drive the transmission disk and the return hook to reset.

[0015] Furthermore, a sealing rubber gasket is bonded to the left side of the assembly column and is located on the circumference of the columnar probe body and is adapted to the flange pipe of the tank body.

[0016] The beneficial effect of adopting the above further solution is that the sealing rubber gasket further strengthens the sealing effect between the assembly column and the tank flange pipe.

[0017] Furthermore, the analysis and processing component includes a signal processing module, a control module, a remote communication module, a buzzer and a warning light. The signal processing module is electrically connected to the fluorescence lifetime sensor, the temperature sensor and the infrared absorption sensor. The control module is electrically connected to the signal processing module, the remote communication module, the buzzer and the warning light. The buzzer and the warning light extend to the right side surface of the protective cover.

[0018] The beneficial effect of adopting the above-mentioned further scheme is that the fluorescence lifetime sensor, temperature sensor and infrared absorption sensor embedded in the left end of the columnar probe monitor the dissolved oxygen, temperature and carbon dioxide concentration in the tank flange pipe in real time, and the signal processing module and the control module analyze and process the data obtained, and then make the control module make corresponding alarm processing according to the changes in dissolved oxygen, temperature and carbon dioxide concentration.

[0019] The present invention also provides a real-time safety monitoring method based on multi-sensor fusion, which is characterized by comprising the following steps: S100: Install the cylindrical probe into the tank flange; S200: The fluorescence lifetime sensor, temperature sensor and infrared absorption sensor embedded in the left end of the columnar probe perform real-time monitoring of the dissolved oxygen, temperature and carbon dioxide concentration in the tank flange pipe; S300: The signal processing module receives and processes the data obtained by the fluorescence lifetime sensor, temperature sensor and infrared absorption sensor; S400: The signal processing module transmits the processed real-time monitoring data to the control module; S500: The control module sends control signals to the remote communication module, buzzer and warning light for graded alarm according to the changes in dissolved oxygen, temperature and carbon dioxide concentration.

[0020] This real-time safety monitoring method based on multi-sensor fusion determines the changes in dissolved oxygen, temperature and carbon dioxide concentration according to the safety thresholds pre-set by the control module. The control module then makes corresponding processing. The first-level alarm control module activates the buzzer and warning light, and the second-level alarm control module activates the remote communication module. The remote communication module notifies engineers via text messages or emails, which has the advantage of multi-level alarms. BRIEF DESCRIPTION OF THE DRAWINGS

The outer side of the hexagonal screw 701 is threadedly connected to a transmission plate 8 that is slidably connected to the slide rods 702. The hexagon socket screw 701 is rotated by an electric wrench. Since the hexagon socket screw 701 is threadedly connected to the transmission plate 8, and the transmission plate 8 is slidably connected to the slide bar 702, the force generated by the rotation of the outer thread of the hexagon socket screw 701 drives the transmission plate 8 to slide on the outer side of the slide bar 702.

Since the hexagonal screw 701 is threadedly connected to the transmission disk 8, and the transmission disk 8 is slidably connected to the slide rod 702, the force generated by the rotation of the outer thread of the hexagonal screw 701 drives the transmission disk 8 to slide on the outside of the slide rod 702; Step 2: When the transmission disc 8 moves toward the end of the return hook 9 located inside the assembly column 6, the side wall of the truncated cone-shaped countersunk hole on the right side of the transmission disc 8 contacts the return hook 9, forcing the return hook 9 to move to the opposite side. At the same time, the return hook 9 contacts the flange at the right end of the tank flange tube 1, and then drives the left side of the assembly column 6 to approach the tank flange tube 1 until they are tightly fitted. The sealing rubber gasket 13 further strengthens the sealing effect between the assembly column 6 and the tank flange tube 1; Step 3: During the above process, the return hook 9 moves to the opposite side, and at the same time, the return spring 102 is squeezed by the stop rod 101, and the return spring 102 elastically contracts, so that the hexagon socket head screw 701 can be reversed later to drive the transmission plate 8 and the return hook 9 to reset.

[0028] Implementation steps for the second innovation point: Step 1: The fluorescence lifetime sensor 3, temperature sensor 4 and infrared absorption sensor 5 embedded at the left end of the columnar probe 2 monitor the dissolved oxygen, temperature and carbon dioxide concentration in the tank flange pipe 1 in real time; Step 2: The signal processing module 121 receives and processes the data acquired by the fluorescence lifetime sensor 3, the temperature sensor 4 and the infrared absorption sensor 5, and transmits the processed real-time monitoring data to the control module 122; Step 3: Based on the safety thresholds preset by the control module 122, the changes in dissolved oxygen, temperature and carbon dioxide concentrations are judged, and the control module 122 makes corresponding processing.
