[0030] Embodiment 1:
[0031] Reference Figure 1-6 , a storage tank telescopic bag operation safety monitoring system, including a pillar 1, a bag body 2 is provided on the surface of the pillar 1, and a distributed optical fiber temperature sensor 3 is bonded to the inner wall of the bag body 2. The number of distributed optical fiber temperature sensors 3 is two, and the two distributed optical fiber temperature sensors 3 are respectively located on the left and right sides of the pillar 1. The distributed optical fiber temperature sensor 3 is realized by using the Bragg diffraction phenomenon in the optical fiber grating. Bragg diffraction is a diffraction effect based on wavelength. Under temperature changes, it will cause the wavelength of the Bragg peak to shift. Specifically, the corresponding temperature change can be deduced by measuring the wavelength change of the Bragg peak. The surface of the bag body 2 is bonded with a clamp 4, and the bag body 2 is fixed to the pillar 1 by the clamp 4. The inner wall of the bag body 2 is bonded with a spiral optical fiber filament 5, and the real-time shape of the bag body 2 is restored by the spiral optical fiber filament 5. The front of the bag body 2 and the front of the pillar 1 are fixedly connected with a support 6, and the inner wall of the support 6 A fiber grating tension sensor 7 is fixedly connected. The fiber grating tension sensor 7 is a sensor based on the grating principle and is used to measure the tensile or compressive deformation of the optical fiber. When the optical fiber in the fiber grating tension sensor 7 is subjected to tension, the tension causes the wavelength of the fiber grating to shift. Then, according to the Bragg formula, the magnitude of the tension can be calculated by detecting the change in the incident light wavelength or diffraction angle. The input end of the distributed optical fiber temperature sensor 3, the input end of the spiral optical fiber filament 5 and the input end of the fiber grating tension sensor 7 are all connected to a transmission optical fiber filament 8. The input end of the transmission optical fiber filament 8 is connected to a demodulator 9. Through the demodulator 9 and the transmission optical fiber filament 8, the initial incident light is emitted into the distributed optical fiber temperature sensor 3, the spiral optical fiber filament 5 and the fiber grating tension sensor 7, and the reflected light reflected by the distributed optical fiber temperature sensor 3, the spiral optical fiber filament 5 and the fiber grating tension sensor 7 is received. The demodulator 9 is connected to a processor 10 via a network cable.
[0032] The processor 10 includes a data acquisition module, a data calculation module, a first comparison module, a data storage module, a feedback module and a wireless transmission module. The output end of the demodulator 9 is electrically connected to the input end of the data acquisition module, the output end of the data acquisition module is electrically connected to the input end of the data calculation module, the output end of the data calculation module is electrically connected to the input end of the first comparison module, the output end of the data storage module is electrically connected to the input end of the data calculation module and the input end of the first comparison module respectively, the output end of the first comparison module is electrically connected to the input end of the feedback module, the output end of the feedback module is electrically connected to the input end of the wireless transmission module, the output end signal of the wireless transmission module is connected to the central control display screen and the mobile device, the wireless transmission module includes a 5G module and a WIFI module, and the mobile device includes a mobile phone and a tablet computer.
[0033] The formula used in the data calculation module is nλ=2Λsin(θ), where n is the order of the grating (usually 1), λ is the wavelength of the incident light, Λ is the period of the grating, and θ is the angle of incidence. When the optical fiber is subjected to tension, the period of the grating will change, thereby changing the value of Λ. By measuring the period change of the grating and combining it with the Bragg formula, the tension can be calculated.
[0034] The formula used in the data calculation module is Δλ=λ*α*ΔT, where Δ is the wavelength shift of the Bragg peak, λ is the length of the incident light, α is the thermal expansion coefficient of the optical fiber material, and ΔT is the temperature change. Under temperature changes, the wavelength of the Bragg peak will shift. By measuring the wavelength change of the Bragg peak, the corresponding temperature change can be deduced.

If the calculation result is equal to the data stored in the data storage module, it means that the data calculation module is operating normally. If the calculation result is not equal to the data stored in the data storage module, it means that the data calculation module is abnormal, and the comparison result is fed back to the central control display screen and the mobile device through the feedback module, so that the user can promptly discover the abnormality of the data calculation module.
[0039] Embodiment 4:
[0040] Reference Figure 4 The output end of the wireless transmission module and the input end of the data storage module are both electrically connected to the data input module. Through the cooperation of the wireless transmission module, the data input module and the data storage module, the user can wirelessly input data into the data storage module through a mobile device.
[0041] In the present invention, when the storage tank telescopic bag operation safety monitoring system is in operation, the demodulator 9 sends initial incident light to the distributed optical fiber temperature sensor 3, the spiral optical fiber filament 5 and the optical fiber Bragg grating tension sensor 7, and receives the reflected light reflected by the distributed optical fiber temperature sensor 3, the spiral optical fiber filament 5 and the optical fiber Bragg grating tension sensor 7. Then, the demodulator 9 transmits the received reflected light data to the data acquisition module, and pre-processes the data through the data acquisition module. The pre-processed data is transmitted to the data calculation module. Then, the data calculation module calculates the received data according to the formula stored in the data storage module, and calculates the current shape, temperature and whether the bag body 2 falls off, and then, the data is transmitted to the data calculation module. The calculation result is compared with the threshold value stored in the data storage module through the first comparison module. If the calculation result is less than the threshold value, it means that the state of the bag cover body 2 is normal. Then, the current state of the bag cover body 2 is transmitted to the wireless transmission module through the feedback module, and through the wireless transmission module, the user can view the current state of the bag cover body 2 on the central control display screen and the mobile device. When the calculation result is greater than the threshold value, the first comparison module generates an alarm message. Then, the current state of the bag cover body 2 and the alarm message are transmitted to the wireless transmission module through the feedback module, and through the wireless transmission module, the central control display screen and the mobile device send out an alarm, and the current state of the bag cover body 2 can be viewed on the central control display screen and the mobile device.
[0042] When the storage tank telescopic bag cover operation safety monitoring system is in self-inspection, the data generation module can periodically send a set of pre-set data to the data calculation module, and the data calculation module calculates the received data, and then the retrieval module extracts the corresponding data according to the data generated by the data generation module and transmits it to the second comparison module, and then the calculated data and the stored data are compared by the second comparison module. If the calculation result is equal to the data stored in the data storage module, it means that the data calculation module is operating normally. If the calculation result is not equal to the data stored in the data storage module, it means that the data calculation module is abnormal, and the comparison result is fed back to the central control display screen and the mobile device through the feedback module. At this time, the user is reminded to repair the storage tank telescopic bag cover operation safety monitoring system in time.
