Abstract
The utility model provides a portable intelligent mass tester, which comprises a casing, a data display unit arranged on the casing, a scale for placing a load, an intelligent measuring circuit connected with a display screen, and a standard mass block with known mass. The intelligent measuring circuit is connected with pressure sensors respectively arranged below the standard mass block and the scale. Through measuring the weight value of the standard mass block with known mass in real-time, the current local acceleration of gravity is calculated by a singlechip, and based on the real-time weight value of an object to be measured and the current local acceleration of gravity, the mass value of the object to be measured is obtained through calculation. The intelligent mass tester not only has high precision, but also has the advantages of simple structure, convenience in use and portability.
Description
Technical field
The utility model relates to a kind of mass measurement instrument, particularly a kind of portable intelligent quality instrument.
Background technology
In the mass measurement field, balance is widely used, but its precise structure, and range is little, and uses loaded down with trivial detailsly, and surface level is first-class such as being placed on, and its result too depends on the correct correction and the precision of counterweight, influenced by environmental factors.At this situation, a kind of electronic balance has appearred on the market, come weighed object physique amount by the electromagnetic force equilibrium principle, though its precision and intelligent degree height, operate comparatively simple, same complex structure, cost is higher, and is unfavorable for carrying.
Summary of the invention
In order to solve the shortcoming that overcomes above-mentioned technology, the utility model proposes a kind of novel portable quality measuring instrument, adopt single-chip microcomputer that the weight of load and standard component is compared, to draw the mass value of load.
The technical solution adopted in the utility model can be described as:
A kind of portable intelligent quality instrument, it comprises shell, be arranged on the data display unit on the shell and use and the scale pan of placing measuring object, described quality instrument also comprises intelligent measure circuit and the known standard quality piece of quality that is connected with described data display unit, described intelligent measure circuit also be separately positioned on the standard quality piece and be connected with pressure transducer under the scale pan.
As a kind of improvement of above technical scheme, described intelligent measure circuit is made up of single-chip microcomputer.
As a kind of improvement of above technical scheme, described data display unit is charactron or LCD panel.
The beneficial effects of the utility model are:
The gravimetric value of the standard quality piece of the known quality by real-time measurement, calculate the acceleration of gravity of current locality by single-chip microcomputer, the mass value that calculates measuring object by the gravimetric value that measures in real time and current, the local acceleration of gravity of measuring object, this intelligent quality instrument is the precision height not only, and it is simple in structure, be easy to use, be easy to carry.
Description of drawings
Fig. 1 is a system architecture diagram of the present utility model.
Embodiment
As shown in Figure 1, a kind of portable intelligent quality instrument, comprise shell, be arranged on the data display unit 1 on the shell and use and the scale pan of placing load, it also comprises intelligent measure circuit 2 and the known standard quality piece 3 of quality that is connected with described data display unit 1, described intelligent measure circuit also be separately positioned on standard quality piece 3 and be connected with 5 with pressure transducer 4 under the scale pan.In the present embodiment, intelligent measure circuit 2 is made up of single-chip microcomputer, is this portable intelligent quality instrument in Fig. 1 frame of broken lines, is measuring object 6 on the frame of broken lines.When having measuring object gravity to be applied on the pressure transducer 5, connect the power supply of system.Two pressure transducers are sent to single-chip microcomputer with the gravity value G1 of the standard quality piece 3 that measures and the gravity value G2 of measuring object 6 respectively, and the quality m1 of known standard mass 3 is stored in the single-chip microcomputer.After single-chip microcomputer receives gravity G1 and G2 data, calculate current, local gravity acceleration g=G1/m1.Calculate the mass value m2=G2/g of measuring object 6 then.And send data display unit to show the result of calculation.Pressure transducer can be any sensor that pressure can be converted to electric current, and standard quality piece 3 is generally got the weight that quality is not perishable, the corrosion of 1kg, and sealing, to make anti-corrosion treatment after-applied on pressure transducer 4.Data display unit 1 can be charactron, LCD panel or other display device.
The quality of this device Intelligent Calculation load also shows that it is simple in structure, and is easy to carry and use.
