Background technology
The method that adopts in the conventional instrument calibrating is: at first add specified voltage or electric current for tested instrument by the scale of tested instrument, by manual observation dial plate pointer indication scale and with the scale that should indicate contrast after, whether the record deviation goes beyond the scope thereby examine and determine out precision.Whenever having observed a scale indication, need to adjust a knob when calibrating, whole process relies on operating personnel to finish by the cooperation of eye, hand, brain fully, and not only consuming time but also require great effort, labour intensity is also bigger.Because each operating personnel's experience and working attitude there are differences.Cause in the verification result human factor too much, had a strong impact on the accuracy and reliability of verification result.
Summary of the invention
The purpose of this utility model provides and a kind ofly not only makes testing result degree of accuracy height, good reliability, and the pointer instrument automatic calibrator that can also reduce labour intensity, increase work efficiency.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: the signal acquiring system that this pointer instrument automatic calibrator comprises fuselage, is arranged on the kinematic train on the fuselage, the control system that is connected with kinematic train and is connected with control system.
Described fuselage comprises brace table and column, and column is fixedlyed connected with brace table; Described kinematic train comprises stepper motor, rotating shaft and rotating disk, and stepper motor is fixed on the column, and rotating disk is fixed on the lower end of rotating shaft, also is provided with crossbeam on column, and rotating shaft is hinged on the crossbeam, and stepper motor is connected with the rotating shaft upper end with belt pulley by belt; Described signal acquiring system is a digital light electrical signal collection device, and digital light electrical signal collection device is fixed on the rotating disk.
Described control system comprises instrument box and is arranged on the interior control circuit of instrument box that control circuit is connected with digital light electrical signal collection device with stepper motor respectively by lead; On instrument box, also be provided with display window.
Described control circuit comprises starting switch, memory circuit, comparator circuit and output display circuit, wherein starting switch is connected with digital light electrical signal collection device with motor respectively, and digital light electrical signal collection device is connected with memory circuit, comparator circuit and output display circuit respectively.
Because this pointer instrument automatic calibrator has adopted the digital light electrical signal collection device under the automatic control, by digital light electrical signal collection device the initial scale of dial plate is carried out static scanning, and pointer position carried out dynamic tracking, after memory circuit by instrument box inside and comparator circuit are compared the data that read and canned data respectively again, draw verification result.Manually read thereby replace fully, realized that dial scale reads robotization, avoided the influence of human factor, improved the accuracy and reliability of verification result verification result.Full-automatic verification process owing to this device need not manual shift again, thereby has alleviated labour intensity, has improved work efficiency greatly.
