As Fig. 2, it is the optical unit partial structurtes schematic diagram of a kind of Biochemical Analyzer light source base linear-movable manner project organization that the present invention designs.Figure comprises light source base 9, work light 4a and standby power source 4b, and two light source internal filaments 5, work light 4a and standby power source 4b are arranged on light source base 9.
As Fig. 3, be the relation of the bracing frame of a kind of Biochemical Analyzer light source base of the present invention linear-movable manner light source base and light source base, and light source base motion track schematic diagram.Figure comprises the bracing frame 18 of light source base, and driving stem 11 is for being arranged on the screw rod on the bracing frame 18 of light source base, and screw rod drives the fixed position on light source base bracing frame 18 to move by drive motor 10, drives light source base 9 to move the replacing realizing light source.
As Fig. 4, it is the track schematic diagram that the light source that designs of the present invention and light source bulb filament and lamp socket move linearly.Figure comprises biochemical instruments optical unit check point 1, and in the device of the present invention's design, on light source base, light source is arranged on the center of lamp socket, and when light source base moves and light source moves, the motion track of light source center is crossing with instrument inspection center's point position overlaps;
And if this light source adopts filament light-emitting bulb to be light source time light source filament position crossing with light source motion track, and filament central point motion track is crossing with instrument inspection center's point position overlaps.
The method of Biochemical Analyzer intelligent light source breakdown judge and replacing, comprises the following steps:
Step 1: when being less than a designated value of less than 45000 when Biochemical Analyzer is in the work of execution once instrument execution water blank detection electric signal AD value, instrument focuses source power supply voltage automatically and stability judges.As supply voltage and rated voltage difference be less than ± 5%, or voltage fluctuation per minute is less than rated voltage 5%, then judge that light source power supply is qualified, otherwise judges that light source power is off quality, and instrument automatic-prompting operator or engineer inspection correct power supply quality.After eliminating power quality issues, and instrument detecting device detectable light signal AD value on the low side time, instrument first automatically starts and detects the automatic focus of work on hand light source, detection signal can not be obtained by automatic focus and reach the AD value intensity of regulation or AD value signal reaches prescribed strength but sensed light signal change is greater than AD200/ minute (stability is bad), and light source power supply meets the requirements, then instrument starts replacing light source operation;
Step 2: the operation of work light refocusing: original-pack have the reaction cup of water to remain on original position, instrument driving motor 10 drives light source base 9 to move along the rectilinear direction of screw rod 11, its concrete act of execution: be set to origination data respectively with the distance within these center line two ends to screw rod 11 slowly each mobile 5mm with this work light seat 9 original position, as in this moving process, photoelectric detector 1 detects the AD value standard that still can not reach and meet the regulation detecting needs, when maybe can not reach the AD value stabilization state of regulation (in 5 minutes, the change of AD value is greater than 200/ minute), instrument then starts changes light source flow process, if but detecting device acquisition sensed signal sources reaches more than appointment AD value in the work light refocusing process of step 2, and light signal stable meet be less than 200AD/ minute then instrument continue to use this light source to detect.In addition, instrument also increases power supply automatic voltage detecting device to power supply quality arbitration functions, when the intelligent function of instrument judges the unstable or deficiency of detection signal whether because power supply caused, power supply caused in this way, instrument starts prompting automatically, and to require that operator or engineer inspection and correction power bad, and do not start replacing light source.
Step 3: light source changed by instrument: after confirmation primary source refocusing is invalid, instrument driving motor 10 rotates and drives screw rod 11 to rotate, automatically working position light source is shifted out original position, standby power source is moved to working position simultaneously, and switch on power by standby power source before mobile, and the power supply of former work light of breaking, and light standby power source and within more than 5 minutes, just start mobile.In moving process, keep detecting device normal operating conditions, detecting the position obtaining maximum AD signal value in optional m igration is the optimum position of standby power source, and is fixed by light source base after its stability of confirmation also meets the demands.So namely, realize automatically completing standby power source and replace former work light flow process, and automatically adopt standby power source to continue to perform Detection task.The light source base of the present invention's design be disc or fan-shaped device time, when carrying out replacing light source, be also, by motor, standby power source is moved to work light position, and after focusing on, standby power supply proceeds to duty, and former working power power-off is in off working state.The present invention design light source fix, with the replacing light source design device of optical fiber movement change light source time, be then motor 10 move drive optical fiber move towards light source one end, to standby power source position be moved at optical fiber and focus on, standby power source is powered, and former work light power-off, thus complete the replacing to light source.
When the cumulative operation time of work light has reached the expected life time of light source, instrument also can directly start replacing light source flow process automatically;
Or instrument does not judge light source power supply quality, allly run into the too low or detection signal stability requirement against regulation of detected signal value, then instrument starts automatic focus automatically, and when instrument automatic focus can not meet instrument testing requirement, instrument then starts replacing light source flow process automatically.The normal request for utilization of instrument then instrument automatic-prompting operator so can not be met as processed successor.
Step 4: after standby power source is enabled, the typical curve of former reservation stopped using automatically by instrument, the data such as scaled values parameter, and automatically require or automatically perform the calibration again of each test item and re-establish typical curve, so far, instrument achieves light source and automatically changes and again correct with instrument, normally can perform Detection task;
When standby power source switches, this device has the self-focusing function of standby power source, standby power source better can be met and detect needs, focusing flow process when starting replacing light source flow process comprises, instrument is powered to standby power source automatically, power more than 5 minutes at standby power source, after light source luminescent signal stabilization, the detection cup that clean water is housed is moved to detecting position by instrument simultaneously, light source base moves towards check point position with the new light sources replaced, the continuous detection light source signal intensity of detecting device in the process of movement, light source autofocus adjustment, best position is selected further by position adjustments when light signal reaches the sensing range suited the requirements, adjustment process completes, instrument can drop into application.
No matter in the various modes of the present invention's design, which kind of design replacing light source or focusing only need a driven by motor light source or fiber optics displacement, and this displacement is the movement of a dimensional space.
This light source switching function also can be realized by manual operation, and namely when work light is not suitable for detecting, instrument automatic-prompting, shifts standby power source onto work light position by hand by operator and realize the switching of standby power source.
After completing replacing light source, instrument acts on prompting user by the either types such as operation interface word, pilot lamp or voice language or various ways simultaneously, and standby power source enabled by instrument, please changes the standby power source of damage as early as possible.Like this after prompting technician nearest at one's leisure between former work light 4a is changed, and when loading onto new qualified light source on this position, eliminate all informations that instrument requirements changes light source simultaneously.Now new clothes light source is just as standby power source, and now the actual light source being in work when be not suitable in use procedure detecting use time, the automatic starter motor 10 of instrument rotates round about, the light source damaged or be not suitable for using is shifted out working position, and new light sources is moved to working position after use.So just can be implemented in and light source base has all the time an available standby power source, just automatically complete replacing light source when instrument needs to change light source at any time.
In the design, standby power source also can be 2 or multiple, can reduce the number of times of manual intervention like this, improves light source for instrument guarantee.
