Abstract
The utility model discloses a digital tester for yarn evenness in the technical field of test, which comprises a sensor, an analogue-to-digital converter, a digital unit and a printing device, wherein, the digital unit is composed of a plurality of universal processing plates which comprises at least one CPU. The universal processing plate are connected in a bus mode. The utility model high the advantages of cost performance, high reliability, convenient adjustment and convenient function expansion.
Description
The utility model relates to the measurement field tests, further relates to the standard metering instrument that a kind of textile industry is used for quality pipe amount.
Fiber strand evenness tester (being called for short the dried instrument of bar) is to be used to measure the pure of various natural fabrics and chemical fibre spin or the quality of blending sliver or the precision electronic device of plucked characteristic.The dried instrument of analog circuit type bar is progressively replaced by the dried instrument of digital circuit type bar owing to there are problems such as circuit complexity, poor stability, platform difference are big.The dried instrument of existing digital type bar has the Uster-3 type of Switzerland and homemade YG131 type at present.The dried instrument of Uster-3 type bar is unfavorable for promoting the use of because operation easier is big, price is high.Then there are problems such as function is few, the partial test data are with a low credibility in the dried instrument of YG131 type bar.
The purpose of this utility model provides a kind of ratio of performance to price height, reliability height, and debugging is convenient, and function is expanded numeric type fiber strand evenness tester easily.
The utility model comprises sensor, analog-digital converter, digital units and PRN device.Digital units is made of the some Universal Process Blade that contain at least one CPU, connects with bus mode between each Universal Process Blade.Sensor is converted to the signal of telecommunication with sliver quality or thickness (non electrical quantity) signal, delivers to digital units after analog-digital converter is converted to data signal.Digital units carries out various processing to the sliver signal, obtains the various parameters of reflection yarn unevenness characteristic, exports the testing journal sheet from PRN device then.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is a block diagram of the present utility model.
Fig. 2 is the syndeton schematic diagram between each Universal Process Blade of digital units.
Fig. 3 is the electrical schematic diagram of Universal Process Blade.
The sensor of being made up of capacitor plate, electric bridge and amplifier etc. (1) is converted to the signal of telecommunication with sliver line density (non electrical quantity) signal, after analog-digital converter (2) is converted to data signal, delivers to digital units (3).What digital units (3) can be controlled sensor (1) moves yarn, roller disengagement etc. certainly; The no sample automatic zero set of also controlled molding number converter (2), mean value are regulated automatically, sampling rate etc.The state that panel (5) is gone up each button is sent to digital units (3), and each led status is subjected to digital units (3) control on it.Under test mode, digital units (3) carries out various real-time processing and non real-time post processing to the sliver signal from analog-digital converter (2), obtains the parameters of reflection yarn unevenness characteristic, then from PRN device (4) output testing journal sheet.
Digital units (3) is made of some Universal Process Blade based on 8751 single-chip microcomputers (8).Every Universal Process Blade (8) all is equivalent to a microcomputer, can independently carry out multiple operations such as computing, processing, management, and they are all received on half-duplex asynchronous communication line (7) and the digital signal bus (6) by twin string line-inset socket.Shared No. one analog-digital converters of all Universal Process Blade (8) (2) are all by the data signal of digital signal bus (6) reception from analog-digital converter (2).Transfer of data between each Universal Process Blade (8) and control are all undertaken by asynchronous communication line (7).Above-mentioned this structure is a kind of bus mode, has that hardware configuration is simple, functional reliability is high, flexible characteristics such as flexible of function.Be equipped with different software for Universal Process Blade (8), can finish different functions.A Universal Process Blade (8) can be finished one or several function, also can finish a function by several Universal Process Blade (8).The quantity of Universal Process Blade (8) determines according to the required function of finishing, and increases or reduce the operate as normal that Universal Process Blade (8) does not influence other Universal Process Blade (8), can be under the situation of not changing hardware and structure the extend testing function.
Universal Process Blade (8) contains at least one CPU(N1), necessary programs and data storage (N1), signal input (12) and gating mouth (11) thereof, several universaling I/O ports (13), middle fracture (10), asynchronous communication mouth (9), reset mouthful (14), DIP switch (S1) etc.Signal input (12) is used to import pending data signal, LS374 data latches (N2 and N3) is equipped with in its inside, utilize gating mouth (11), can be independent of the control of CPU and data on the receiving digital signals bus (6), thereby improved the time availability of CPU.Universaling I/O port (13) is used to input or output some status signal or control signal, as key-press status signal on the panel (5) or indicator lamp control signal, or some parallel data of input and output, as be sent to PRN device (4) treat print data etc.Middle fracture (10) is used to handle some emergencies, as starts or stops test etc.Asynchronous communication mouth (9) links to each other with asynchronous communication line (7), is used to carry out transfer of data and control between each Universal Process Blade (8).DIP switch (S1) is realized with the form of digital quantity some parameter being finely tuned by means of CPU, compare with analog quantity micro actuator (as potentiometer etc.), have characteristics such as stable, reliable, flexible, easy to adjust, can obviously reduce platform poor, reduce debugging requirement to sensor (1) and analog-digital converter (2).A DIP switch can be used as a digital micro actuator and uses, and also can be separated into several digital trimming devices and use.The also available dial-up dish of DIP switch replaces.
Analog-digital converter (2) comprises one tunnel 12 ADC chip, is based on AD574 and designs.Sensor (1) adopts condenser type.PRN device (4) is general nine kinds of needles dot-matrix printer, also can use plotter.
The utility model has been realized the test function of indexs such as the coefficient of variation, fault, wave spectrum, variance-length curve, deviation ratio.Digital units is formed by connecting by the mode of some Universal Process Blade with bus, has the flexible flexible characteristic of function, can be under the situation of not changing hardware and structure the extend testing function.Universal Process Blade is equipped with the digital trimming device, and it is poor obviously to reduce platform, reduces the debugging requirement.One cutting links such as transfer of data between each Universal Process Blade and control are finished by the half-duplex asynchronous communication, have simplified hardware and structure, have improved functional reliability.All Universal Process Blade only uses No. one analog-digital converter, has further simplified hardware, has reduced cost.Signal input on the Universal Process Blade can be independent of the control of CPU and receive data, has improved the time availability of CPU.Universal Process Blade is based on 51 series monolithics and designs, and has the very high ratio of performance to price.Various operations are all undertaken by the button on the panel, have convenience operation.
