After vertically fixing the connection base 12 to the bottom ring wall plate 7 of the tank and horizontally fixing the base 4 to the edge plate 6 of the tank, the worker can measure the distance between the axis of the measuring part 32 of the displacement meter 3 to the bottom surface of the connection base 12 and store it in the computer device.
After receiving the displacement amount a transmitted by the communication part, the distance b between the axis of the measuring part and the bottom surface of the connecting base, which is stored in advance, is acquired.
S503, the computer equipment determines the change amount of the included angle between the bottom ring wallboard and the edge board based on the displacement amount and the distance.
When the computer device receives the displacement amount a sent by the communication component, based on the distance b between the axis of the pre-stored measuring component and the bottom surface of the connecting base, the change amount θ of the included angle between the bottom ring wall plate and the edge plate can be calculated according to the following formula.
tanθ=a/b
I.e.
θ=tan-1(a/b) (1)
Where θ is the amount of change in the angle between the bottom ring wall plate 7 and the edge plate 6, a is the amount of displacement that changes between the housing 31 and the measuring member 32, and b is the distance between the axis of the measuring member 32 and the bottom surface of the connection base 12.
The technical staff can preset a displacement threshold value or an included angle change quantity threshold value of the bottom ring wall plate and the edge plate, when the received value of the displacement a is larger than or equal to the displacement threshold value or the included angle change quantity theta calculated according to the received displacement a is larger than or equal to the included angle change quantity threshold value, warning reminding information is sent to the technical staff, the technical staff can replace or maintain the storage tank to a certain degree based on the warning reminding information, and the technical staff can check the included angle change quantity theta on computer equipment at any time.
In embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless explicitly defined otherwise.
The foregoing description of the preferred embodiments of the present application is not intended to limit the application, but rather, the application is to be construed as limited to the appended claims.
