Description
[technical field]
The present invention relates to a kind of detection calibration equipment of financial.
[background technology]
We know, financial (paper money counter, currency counting and detecting machine etc.) needs to correct its sensor signal, CIS signal (if sometimes), sequence number discrimination (if sometimes), anti-counterfeit recognition rate, code-disc speed etc. before dispatching from the factory, at this moment just need the information such as the sensor signal obtaining financial, CIS signal (if fruit has), program operation information, code-disc speed, and then detect.In addition, financial is after dispatching from the factory, arrived after dealer or user employ a period of time on hand, the signals such as the transducing signal in it likely can change (gain or decay) and affect the use of whole utensil, at this moment also need the transducing signal, code-disc speed etc. that carry out detecting it.
Therefore, financial is before dispatching from the factory or dispatch from the factory and often all need to detect after using a period of time.Present stage, when detecting financial, there is following deficiency:
One, in the sensor signal gathering financial: current, the detection of financial before dispatching from the factory is all generally the method using oscillograph directly to observe, due to the many and distinct of the number of sensors that uses of financial inside, often need to use one or more multichannel oscillograph to go to gather these signals, not only acquisition step is complicated, wiring is loaded down with trivial details for this, also needs a large amount of funds to buy these oscillographs.Certainly, also the equipment that some multiple signals gather simultaneously is had in other field, but this equipment to use outside trigger pip, and due to many signals of financial be all use code-disc pulse as collection benchmark, such equipment can not meet the demand of financial collecting sensor signal.Moreover if financial has left producer arrived user on hand, at this moment then seldom user or dealer have had the sensor signal that such equipment goes to detect financial.
When two, gathering the CIS image correcting financial: present stage, when carrying out detection CIS image to financial, is all generally use external circuits to test financial or directly to use oscillograph to detect online.Due to the electron device that CIS is a condition of work more complicated, the certain peripheral circuit of its need of work coordinates, therefore its maintenance uses a peripheral circuit by its work and use the analysis tools such as logic analyser to carry out imaging analysis to the signal collected.Also have directly on destination financial utensil, use himself hardware, by walking the pattern paper of a black and crossing a pure white pattern paper, utilize hyperchannel oscillograph simply observe signal thus judge the situation of CIS.These maintenance ways all have high, the inadequate shortcoming intuitively of cost, and the image of the image obtained and financial itself often has some difference.Once after financial dispatches from the factory, these conditions are difficult to realize in user or dealer's hand.
Three, when cycle tests discrimination: general staff check and correction or the use log file of using carries out discrimination test by special computer program by the log file of evaluating objects financial.The former need tester one by one the sequence number of contrastive test bank note and machine recognition sequence number out have inerrancy, efficiency is very low.The latter needs to write special program for the log file saving format of destination financial utensil, and portability of program is low, and could process after will importing the log file of destination financial utensil, just how can not know discrimination in testing.
Four, when testing code-disc speed: the general oscillograph that uses directly is measured.Such test mode its essence is the spacing read in code-disc signal before random two continuous code-disc signals, and this needs an oscillograph to complete.In addition, because when the operation of reality, the code-disc speed of cash inspecting machine is not an absolute fixed value, such test can only measure the speed of the signal representative between these two signals, the average velocity of code-disc within a period of time can not be represented, therefore the code-disc speed accuracy tested out like this is lower, is difficult to really obtain the real code-disc speed of financial.
Five, when obtaining program operation information: when the work of destination financial utensil is abnormal, the state obtaining the controller of current goal financial inside is very valuable, these information can characterize the state of current controller, help developer to understand mistake why can occur, or the scene of reduction mistake (reappearing the same mistake), thus improve accordingly.Current, the operation information of the program that developer will live must download emulation by the emulator using this control chip special by special cable, reduce simultaneously mistake scene can gather mistake occur time processor information, this operating efficiency is low, and require higher to operating personnel's Specialized Quality, outside producer, substantially do not possess such condition.
