Abstract
Biochip reading system, including computer, CCD, slide holder, its characterized in that: a uniform lighting system is added between the CCD and the slide holder, and a slide holder control circuit is arranged to control the automatic in and out of the slide holder, wherein the uniform lighting system consists of a large divergence angle light emitting diode and an optical equalizer positioned below the large divergence angle light emitting diode; the control circuit of the slide holder is composed of a single chip microcomputer, a motor power supply, a motor, a relay A for controlling the power supply of the motor to be switched on, a relay B and a relay C for enabling the motor to be combined in an attracting mode and a disconnecting mode. The invention ensures that the biochip reading system is uniformly illuminated in the detection process, the slide holder can automatically enter and exit, the accuracy of detection data is ensured, and the invention has the advantages of simple structure, easy realization, economy, safety and reliability.
Description
Affiliated technical field
The present invention relates to a kind ofly have even illumination and slide holder automatically into and out of the biochip reading system of control circuit.
Technical background
In biochip reading system testing process, for small size, closely illumination is prone to ZhaoMing Center with general means of illumination and crosses bright or the phenomenon of blackspot on every side, if to the illumination unevenness of print, then on the detection data of print very big error can appear.In addition, the testing staff will constantly be put, be got the chip of detection in testing process, if at every turn all will be, draw slide holder with hand push, and complex operation so not only, and easily cause the cross pollution of detected print in the testing process, make prohibited data detection true.
Summary of the invention
Technology of the present invention is dealt with problems and is: for the unevenness that solves illumination and overcome the problem that manual push-and-pull slide holder is brought, design and a kind ofly have even illumination and slide holder automatically into and out of the biochip reading system of control circuit, make that the biochip reading system throws light on evenly, slide holder can pass in and out automatically in testing process, accurate to guarantee detecting data.
The technical solution adopted for the present invention to solve the technical problems is: the biochip reading system, comprise computing machine, CCD, slide holder, it is characterized in that: between CCD and slide holder, add uniform illumination system, the automatic turnover of slide holder control circuit control slide holder is set simultaneously.
Described uniform illumination system is by forming with the big Optical Equalizer that looses the angle light emitting diode and install below it.
Relay A, relay B and the relay C that makes motor carry out adhesive and open combinations that described slide holder control circuit is connected by single-chip microcomputer, motor power, motor, control motor power form, by Single-chip Controlling relay A, make motor power open and close, Single-chip Controlling relay B and the adhesive of relay C and the combination of disconnection simultaneously, motor is changed turn to, realize that slide holder passes in and out automatically.
Principle of the present invention is: the big uniform illumination system that looses angle light emitting diode and Optical Equalizer composition of employing can remove ZhaoMing Center's bright spot and the blackspot on every side that throws light on, and realizes evenly illumination; When slide holder need move, the single-chip microcomputer in the slide glass control circuit sent control signal to relay B and relay C as required, and relay changes the adhesive combination, made motor change sense of rotation, thereby drove the turnover of slide holder.Detected print is sent into detection system by slide holder, gathers the image of detected print after uniform illumination system illuminates by CCD, and CCD gives the data delivery that collects computing machine and finishes data collection and analysis by computing machine.
The invention has the beneficial effects as follows: the uniform illumination system with big loose angle light emitting diode and Optical Equalizer composition is simple in structure, easily realizes; And the estrade control circuit has guaranteed just to walk after the reliable commutation of motor, the misoperation of having avoided estrade in the motor commutation process, might occur effectively, and this control circuit is simple in structure, and has not only economy but also safe and reliable advantage.
Description of drawings
Fig. 1 is that system of the present invention forms theory diagram;
Fig. 2 is the uniform illumination system structural representation among Fig. 1.
Embodiment
As shown in Figure 1, the embodiment of the invention is made up of computing machine 10, CCD9, uniform illumination system 8, motor power 1, relay A2, single-chip microcomputer 3, relay B4, relay C5, motor 6, slide holder 7.After system opened electricity, uniform illumination system 8 was radiated at even illumination light on the slide holder 7, gathers the image of tested print by CCD9, and sent into computing machine 10 and carry out data processing.Slide holder 7 into and out of being that the change of motor 6 sense of rotation by driving its walking realizes.After start resetted, slide holder 7 was in closed condition.When slide holder 7 need stretch out operation, 3 of single-chip microcomputers send control signal to relay B4, relay C5 as required, relay B4, relay C5 carry out the adhesive combination, make the voltage at motor 6 two ends be+the V direction, after this, single-chip microcomputer 3 pilot relay A2 power up motor 6, and 7 of slide holders are to stretching out the direction operation.When slide holder 7 need be return operation, 3 of single-chip microcomputers send reverse control signal to relay B4, relay C5 as required, relay B4, relay C5 carry out reverse adhesive combination, the voltage at motor 6 two ends is become-the V direction, after motor commutation is finished, single-chip microcomputer 3 pilot relay A2 once more powers up motor 6, and then slide holder 7 is to the direction operation of returning.
As shown in Figure 2, uniform illumination system 8 is made up of eight light emitting diode 81 and Optical Equalizers 82 with Vernonia parishii Hook angle that are installed on the ring, eight light emitting diodes 81 are evenly distributed on 360 degree circles, and connect with certain angle of inclination with series system.Optical Equalizer 82 is to be made of translucent optical mirror slip, it be installed in light emitting diode 81 below.
