One, technical field
The present invention relates to a kind of measurement sorting unit, specifically a kind of semi-automatic separator of switching Hall components.
Two, background technology
Hall device can be made response to the variation in magnetic field, thereby can be applied to industry and civilian control field.
According to the different modes to magnetic responsiveness, hall device is divided into linear unit and switching mode device.For the switching mode device, under certain magnetic field condition, only reach certain specific requirement, just can think certified products.In certified products,, need carry out the specification classification to the switching mode hall device according to the difference of response device sensitivity.
At present switching Hall components is adopted mostly the mode of artificial separation, the artificial separation device generally is made up of a plurality of voltmeters, ammeter, potentiometer, indicator lamp etc., need the manual adjustment magnetizing current to change the magnetic field size, and by switch change magnetic direction, come the decision device classification by reading or the status indicator lamp of observing ammeter, voltmeter again, thereby the False Rate height; And do not have the statistic of classification function, efficiency is extremely low.
Three, summary of the invention
The purpose of this invention is to provide a kind of semi-automatic separator of switching Hall components, this sorting unit can be according to setting, automatically regulate the size and the direction in magnetic field, online magnetic field is detected, and automatically device is carried out specification classification and quantity statistics according to the response condition of device.
The objective of the invention is to be achieved through the following technical solutions:
A kind of semi-automatic separator of switching Hall components, it is characterized in that: it comprises control module, field generating unit, state detection unit, status display unit and input block, described control module is accepted the signal of input block, and the size of current and the direction in field generating unit generation magnetic field are controlled; State detection unit feeds back to control module with the detected magnetic field situation (size and Orientation) that is used for the switching Hall components measurement; Control module receives the output signal of the tested switching Hall components that is arranged in magnetic field; Control module is judged, is classified the specification of the switching Hall components surveyed according to predefined class definition, and by status display unit measured result is shown.
Among the present invention, control module is the control core with the single-chip microcomputer, by additional peripheral circuitry driving magnetic field generating unit, state detection unit, status display unit, input block etc.Single-chip microcomputer carries out the differential counting statistics according to detected state to measuring element, when reaching some, gives prompting.
Field generating unit utilizes electromagnet to produce magnetic field, and the maximum magnetic induction in the magnet gap reaches about 2000 Gausses.The Single-chip Controlling current feedback circuit, thus the size and Orientation of the magnetizing current that produces magnetic field can be controlled; According to measuring purpose, control module can be finished the alternation step by step in magnetic field and the change of magnetic direction automatically.
State detection unit is utilized the linear hall-effect device of known features, detects the size and Orientation in the magnetic field that field generating unit produced that is used for measuring switch type Hall element, thereby reaches the purpose that FEEDBACK CONTROL is regulated magnetic field, guarantees certainty of measurement; Be arranged in the detected state of Hall switch device under corresponding magnetic field in magnetic field, reach the TTL logic level, directly read by single-chip microcomputer through signal condition.Through with criteria for classification relatively after, single-chip microcomputer draws the measured device specification.
Status display unit is presented at the indicator lamp of measured device specification with different colours on the instrument panel, and the digital display circuit of MCU driving shows statistical counting simultaneously.
Input block sends to control module by special-purpose enter key and detects instruction; Can also the leaf through counting situation of detected different size device of enter key; Can the count initialized value.
Among the present invention, measurement data is kept in the data buffer zone of single-chip microcomputer.Described control module is connected with the PC computer, and measurement data and relevant communication instruction are combined into packet send the PC computer to.
The present invention can be according to measuring process, automatically change the direction and the size of the magnetizing current of electromagnet, according to class definition in advance, automatically the specification of decision device classification, thereby device is carried out sorting, and, showing corresponding indicating status according to the device specification of automatic differentiation, the device to different size carries out statistic of classification and sum statistics automatically simultaneously.Compared with prior art, the present invention has reduced the manual intervention in the measuring process, and accuracy of detection is good, the detection efficiency height, and labour intensity is little.
