Wherein, optical strain gauge theory of operation: when the strain of the environment where the fiber grating is located changes, the period of the grating or the refractive index of the fiber core changes, so that the wavelength of reflected light changes, and the change condition of the strain can be obtained by measuring the change of the wavelength of the reflected light before and after the strain change.
The working principle of the resistance strain gauge is as follows:
when the measured part is subjected to linear deformation along the direction of the resistance wire, the resistance wire is deformed (extended or shortened) along with the resistance wire, so that the resistance of the resistance wire is changed (increased or reduced), the change value is in direct proportion to the strain on the surface of the part adhered with the strain gauge, and finally, the change condition of the strain capacity can be obtained by measuring the change condition of the electric signal of the strain gauge.
The battery unit 1-1-02 is composed of one or more of dry batteries, lead storage batteries, lithium batteries and solar batteries.
The working principle of the embodiment is as follows: when the gas cylinder is charged or discharged, the deformation of the gas cylinder body causes the strain sensing device 3 to generate a strain signal, the strain signal is transmitted to the signal acquisition processing device 1-1 in the signal processing integrated module 1 through the signal wire 4, the signal is analyzed by the signal acquisition processing device 1-1 and transmitted to the signal display device 1-2, the signal display device 1-2 displays the pressure value in the pressure dial 1-2-01 through pointer scales, the pressure range is displayed in the pressure zone disc 1-2-02 through a pointer and different lights, wherein the pressure zone disc is set to be a low pressure zone in a range from zero to half of rated working pressure, a medium pressure zone in a range from half of rated working pressure to rated working pressure, a high pressure zone beyond the rated working pressure, and when the gas cylinder pressure is respectively in the three zones, the alarm lamps 1-2-03 are respectively lightened in yellow, green and red colors. The maximum strain value distribution position of the gas cylinder is displayed by lamplight in a strain position display table 1-2-04, the maximum strain value is real-time maximum strain at each position of A, B, C of the gas cylinder, namely when the gas cylinder is used, if the strain value at the position A exceeds the strain value at the position A when the rated working pressure of the gas cylinder is exceeded, the lamp at the area A is on, and similarly, when the strain value at the position B exceeds the strain value at the position B when the rated working pressure is exceeded, the lamp at the area B is on, and the area C is similar.
Through each index displayed by the signal display device 1-2, the using state of the gas cylinder and the strain condition of each part can be easily observed, and the health of the gas cylinder can be monitored in real time.
Wherein, the transformation principle of strain and pressure:
when the gas cylinder is inflated and deflated, the cylinder body expands and contracts along with the change of the pressure of the gas cylinder, so that the strain sensor on the surface of the cylinder body can also generate the change of a strain signal, namely the charging pressure of the gas cylinder and the strain value generated by the strain sensor have a corresponding relation, as shown in fig. 5.
Therefore, an empirical formula Y = F (X) or X = F of the filling pressure Y of a certain gas cylinder and the dependent variable X at a certain position of the bottle body can be obtained according to the corresponding relation between the two -1 And (Y) editing and designing a signal analysis module in the signal processing integration according to the empirical formula, so that the dependent variable of the gas cylinder can be converted into a pressure value.
