Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
See Fig. 1, be depicted as embodiment of the invention theory diagram.This intelligent dynamometer comprises sensor interface, signal processing circuit and display screen 9, and described sensor interface has one or more; Described signal processing circuit comprises one or more amplifier A3, traffic pilot 4, amplifier B5, analog to digital conversion circuit 6, counter 7 and CPU8, wherein one or more sensor interfaces are connected with one or more amplifier A3 respectively, the output termination traffic pilot 4 of amplifier A3, the output terminal of traffic pilot 4 meets CPU8 through analog to digital conversion circuit 6, counter 7 successively.
The calibrating procedure that in the storer of instrument, has system or instrument, or different sensors demarcated respectively, and the storage calibration result; Also have logging program, the static measurement result is carried out record; Also have dynamic dynamometry program, carry out dynamic dynamometry.Inquiry, print routine can be measured and print (CPU8 directly links to each other with printer) measurement result.Also have operation keyboard 11 to link to each other on the instrument with CPU8.
Described display screen 9 is single LCD or two LCD LCDs, but Chinese display; RS-232 interface is arranged on the dynamometer, can carry out data communication.
Fig. 3 is an embodiment of the invention general flow chart.Comprising four subroutines, respectively shown in Fig. 4-7.Fig. 4 is the embodiment of the invention " record " subroutine flow chart.Fig. 5 is the embodiment of the invention " inquiry " subroutine flow chart.Fig. 6 is the embodiment of the invention " demarcation " subroutine flow chart.Fig. 7 is the embodiment of the invention " dynamically dynamometry " subroutine flow chart.
The electric signal of various force cell 2 outputs is delivered to traffic pilot 4 after high-precision amplifying A3 amplifies.Amplify through one-level, link 16 high-speed a/d converters (i.e. analog to digital converter among the figure) 6, simulating signal is become digital signal send counter 7, CPU8 reads digital quantity from counter 7 again.By processing to digital quantity, send LCD dot matrix screen (being display screen 9) to show result, can select to store this data as required.The operation of instrument is finished by keyboard 11 according to the single prompting of Brunei in the screen.Connect printer 10 by parallel port, link to each other with principal computer by RS-232 mouth 12.
The principle of work of this instrument following (seeing accompanying drawing one): timing signal, proof force value 1 is put on the sensor 2, sensor 2 is connected to sensor interface, proof force value 1 is proportional to the simulating signal of sensor 2 outputs, be proportional to the digital signal of counter 7 outputs, be proportional to the digital quantity that display 9 shows.Therefore, there is following relationship in the digital quantity of proof force value 1 and display 9 demonstrations:
The digital quantity k that proof force value 1=Kx display shows is a coefficient, is chosen automatically by computing machine.The digital quantity that display shows (code value in the instrument), multiply by a certain constant after, send display to show again, what at this moment display showed is exactly proof force value 1 (software configuration is seen accompanying drawing 3 accompanying drawings 4).
During use,, link to each other with relevant sensor 2 respectively, after sensor 2 is numbered, demarcate according to the difference of application target.Nominal data is deposited in computing machine.As checking the stressing conditions of certain sensor 2, only need this sensor 2 is connected to instrument signal input end (the proof force value among Fig. 1 changes the testing force value into), import the numbering of this sensor 2 again, just can measure (can connect 99 sensors 2 at most) one by one.When measuring, data recording is got off.So that inquire about or send principal computer analysis.This instrument also is provided with a passage can carry out dynamic dynamometry, and keeps maximal value (flow process such as Fig. 7).The use of instrument is to carry out under the prompting of middle Brunei list, operates very simple.And provide real-time time to show, the indication of number star voltage, undervoltage warning, the function of shutting down automatically.Instrument can connect mini-printer 10 or line printer 10, printable dynamometry curve or form.
The accuracy of an instrument reaches 0.05 grade, working temperature 040t; Adopt suitcase structure (accompanying drawing 2), internal battery is convenient to field work.
As required, instrument can make multi-point temperature measurement into, pressure detection, the instrument of weighing etc. and to use.Therefore, this instrument is the intelligent dynamometer table on the many ways of a kind of global function, will be used widely in various industries.
