Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
At present, the measurement and calculation of the inflated helium quantity are mainly divided into two methods, namely a method for measuring the total quantity of helium filled into an aerostat and a method for measuring and accounting the residual helium quantity of a high-pressure helium container. The former method generally performs an additive calculation of the total helium gas by connecting a flowmeter in series between high-pressure helium gas pipes. The latter algorithm typically performs an accounting of the total helium content by measuring the state of the helium inside the high pressure vessel. Since the measurement accuracy of the former is directly determined by the accuracy of the flowmeter, the high pressure change flow rate of the helium gas inflation process of the aerostat is fast. The requirement for realizing high-precision measurement is high on the flowmeter, however, the high-precision flowmeter has high cost and large accumulation of process errors for unsteady flow measurement for a long time. Accounting of the total amount of aerostat helium charge is therefore dependent on the second method.
The key to the second algorithm for accounting the total amount of high pressure helium is how accurately the condition inside the high pressure vessel is measured. The core of the second method is that the mass of helium left in the high-pressure container is calculated each time, and the total mass of helium in the initial state of each inflation minus the total mass of helium in the end state is the total inflation amount of all helium in the inflation process. The high pressure helium affects the density of helium within the vessel depending on the pressure of the high pressure helium and the helium temperature. And obtaining helium density by measuring the temperature and pressure and looking up the table difference value, and calculating the medium mass of helium.
However, according to the analysis of the actual inflation process conditions, the arrangement of the gas temperature sensor inside the high-pressure helium bottle is hardly realized.
In order to solve the above problems, the multi-path temperature distribution measuring aerostat inflation amount measuring system according to the present invention will be described with reference to fig. 1, in which an aerostat 100 is disposed in an aerostat storage area, the aerostat 100 is communicated with an inflation bottle 300 through an inflation pipe 200, and the inflation bottle 300 can inflate the aerostat through the inflation pipe 200. Depending on the different needs of the inflation, the inflation bottle 300 may be a helium bottle or other gas bottle.
As shown in fig. 1, the multi-path temperature distribution measurement aerostat inflation amount measurement system includes: a pressure sensor 400, an accounting terminal 500, and a temperature sensor 600.

The first charge of the aerostat 100 may be determined based on the first mass and the second mass. Wherein first charge = first mass-second mass.
According to the multi-path temperature distribution measurement aerostat inflation volume measurement system provided by the invention, the pressure sensor 400 is arranged at the bottle mouth of the air charge bottle 300, the temperature sensor 600 is arranged on the air charge bottle 300, and the accounting terminal 500 is electrically connected with the pressure sensor 400 and the temperature sensor 600, so that the accounting terminal 500 controls the pressure sensor 400 and the temperature sensor 600 to acquire initial pressure and initial temperature in the air charge bottle 300 before the air charge bottle 300 is inflated, and the accounting terminal 500 controls the pressure sensor 400 and the temperature sensor 600 to acquire current pressure and current temperature in the air charge bottle 300 after the air charge bottle 300 is inflated, so that the first inflation volume of the aerostat 100 is determined through the initial pressure, the initial temperature, the current pressure and the current temperature, and the measurement accuracy of the aerostat 100 at the maximum can be greatly improved through the measurement mode, and the static buoyancy of the aerostat 100 can be accurately calculated, so that the most important technical support is provided for the success of the test of various aerostat 100.
