[embodiment]
Consulting shown in Figure 1ly, is the hardware structure figure of dynamometer automatic correction system of the present invention.This dynamometer automatic correction system comprises the measurement board 15 of a user end computer 11 and placement dynamometer to be corrected.One load sensor 18 is installed on this measurement board 15.One dynamometer 17 to be corrected places to be measured on the board 15, and links to each other with load sensor 18.This load sensor 18 is used for force measurement, and the gauge outfit 19 of a demonstration load sensor 18 readings is installed on it.
Consulting shown in Figure 2ly, is the functional block diagram of user end computer of the present invention.This user end computer 11 comprises a system initialization module 111, a judge module 112, a data acquisition module 113 and an order sending module 114.System initialization module 111 is used to start this corrective system, sets item number, kind, check point, number of corrections, the correction tasks of dynamometer 17 to be corrected, and the reading of load sensor 18 is made zero.Judge module 112 is used to judge whether dynamometer 17 item numbers to be corrected are set, whether the reading of load sensor 18 receives, whether the reading of load sensor 18 makes zero, whether dynamometer 17 to be corrected arrives check point, whether the check point of dynamometer 17 to be corrected is all proofreaied and correct finishes, this correction tasks of dynamometer 17 to be corrected whether finish and the difference of judging load sensor 18 readings and dynamometer to be corrected 17 readings whether in allowing accuracy rating etc.Data acquisition module 113 is used to obtain the reading of dynamometer 17 to be corrected, the reading of load sensor gauge outfit 19 etc.Order sending module 114 is used for sending corrective command to measuring board 15.
Wherein, the kind of dynamometer has two kinds, and one is electronic type, and one is mechanical.The check point of dynamometer can be set before each the correction, for example for one 50 kilograms electronic type dynamometer, can be by ten kilograms of check points, totally five check points are respectively: ten kilograms, 20 kilograms, 30 kilograms, 40 kilograms and 50 kilograms.The electronic type dynamometer can adopt the operator scheme of pulling force and pressure to measure when using, so its correction tasks has two during correcting electronic formula dynamometer: one for proofreading and correct the pulling force mode; One is the calibrating (base measuring) pressure mode.Five check points when just having when proofreading and correct the pulling force mode five check points and calibrating (base measuring) pressure mode for 50 kilograms electronic type dynamometers.And, can establish five check points equally, but the mechanical type dynamometer has only a kind of metering system of pulling force, so the correction tasks of mechanical type dynamometer has only one promptly to proofread and correct the pulling force mode for one 50 kilograms mechanical type dynamometer.
Consulting shown in Figure 3ly, is the automatic bearing calibration process flow diagram of dynamometer of the present invention.At first, start this corrective system and carry out system initialization by system initialization module 111, comprise the item number of setting dynamometer 17 to be corrected, kind, maximum range (unit K g), allow parameter such as accuracy rating, whether test can receive the reading of load sensor 18, and (step 300) again makes zero the reading of load sensor 18.In this step S300, if the kind of dynamometer to be corrected 17 is electronic type dynamometers, then its measured value can be acquired and be presented on the screen of user end computer 11 by the RS-232C interface; If the tensile force type dynamometer, then its measured value can directly be read by the user and be entered into user end computer 11 then, and shows.
After the system initialization, receive the correction tasks of being selected according to the kind of dynamometer 17 to be corrected by the user, dynamometer 17 to be corrected can be the electronic type dynamometer, also can be the mechanical type dynamometer.Dual mode is drawn, pressed to the correction tasks of electronic type dynamometer, and the correction tasks of mechanical type dynamometer is only drawn a kind of mode (step S301).Send corrective command by order sending module 114 and control dynamometer 17 side-to-side movements to be corrected (step S308).Judge by judge module 112 whether this dynamometer 17 to be corrected arrives check point (step S310).If this dynamometer 17 to be corrected does not arrive check point, then return step S308, if this dynamometer 17 to be corrected arrives check point, then send these dynamometer 17 stop motions to be corrected of order control, and wait for the stable reading (step S312) of load sensor 18 and this dynamometer 17 to be corrected by order sending module 114.Judge whether the reading of load sensor 18 and dynamometer to be corrected 17 stablizes (step S314).If unstable, then return step S312 and continue to wait for, if the reading of the two is stable, then obtain the reading (step S316) of load sensor 18 and dynamometer 17 to be corrected simultaneously.Above-mentioned reading is stored to data storage district 20 (step S317).Whether the difference of reading of judging the reading of this load sensor 18 and dynamometer to be corrected 17 is in allowing accuracy rating (step S318).If the difference of the two is not in allowing accuracy rating, this check point that then will this dynamometer 17 to be corrected is labeled as defective, enters step S319 (step S322) again; If the difference of the two is in allowing accuracy rating then judge whether to arrive last check point (step S319) again.For example: 50 kilograms dynamometer can have five check points, it is respectively ten kilograms, 20 kilograms, 30 kilograms, 40 kilograms and 50 kilograms, after arriving ten kilograms of first check points, obtain reading and send order again and control dynamometer to be corrected 17 and continue motion and arrive second check point, all proofread and correct up to all check points and finish.So in this step S319,, then return step S308, if arrive last check point then judge this correction tasks whether finish (step S320) if do not arrive last check point.If in step S320, judge that drawing correction tasks does not finish, then return step S301 and receive the another kind of correction tasks that the user selects, re-execute this flow process; Draw that correction tasks has finished then with the mode remittance abroad of all correction datas if judge with electrical form (Excel), and, finish this correction (step S328) with the difference mark of the reading of the reading of the load sensor 18 of underproof check point and dynamometer to be corrected 17 come out (step S324).
