Description
[technical field]
The utility model relates to a kind of detection calibration equipment of financial utensil.
[background technology]
We know, finance utensil (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 to be to information such as the sensor signal of obtaining financial utensil, CIS signal (if fruit has), program operation information, code-disc speed, and then detected.In addition, the finance utensil is after dispatching from the factory, arrived after dealer or user used a period of time on hand, the signals such as transducing signal in it likely can change (gain or decay) and affect the use of whole utensil, at this moment also need to be detected its transducing signal, code-disc speed etc.
Therefore, financial utensil before dispatching from the factory or dispatch from the factory and use a period of time after often all need to be detected.Present stage, when financial utensil is detected, there is following deficiency:
One, aspect the sensor signal that gathers financial utensil: current, the detection of finance utensil before dispatching from the factory is all generally the method for using oscillograph directly to observe, the number of sensors of using due to financial utensil inside is many and kind is different, often need to use one or more multichannel oscillographs to remove 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, the equipment that also has some a plurality of signals simultaneously to gather in other field, but this equipment is to use outside trigger pip, and, because many signals of financial utensil are all to use the code-disc pulse as gathering benchmark, such equipment can not meet the demand of financial utensil collecting sensor signal.Moreover, if having left producer, financial utensil arrived the user on hand, at this moment seldom user or dealer have the sensor signal that such equipment removes to detect financial utensil.
While two, gathering the CIS image of correcting financial utensil: present stage, when financial utensil is detected to the CIS image, is all generally to test financial utensil or directly use online oscillograph to detect with external circuits.Because CIS is the electron device of a condition of work more complicated, the certain peripheral circuit of its need of work coordinates, thus its maintenance many with a peripheral circuit by its work and with analysis instruments such as logic analysers, the signal collected is carried out to imaging analysis.Also have directly on target finance utensil, use himself hardware, the pattern paper by walking a black and cross a pure white pattern paper, thus utilize the hyperchannel oscillograph signal simply to be observed to the situation of judgement CIS.These maintenance ways all have that cost is high, the image of shortcoming, and the image obtained not intuitively and financial utensil itself often has some difference.Once, after financial utensil dispatches from the factory, these conditions are difficult to realize in user or dealer's hand.
Three, when the cycle tests discrimination: generally use staff check and correction or use log file that the log file by evaluating objects finance utensil carries out the discrimination test by special-purpose computer program.The former need the tester one by one sequence number and the machine recognition sequence number out of contrastive test bank note inerrancy is arranged, efficiency is very low.The latter need to write special-purpose program for the log file saving format of target finance utensil, and portability of program is low, and could process after will importing the log file of target finance utensil, can not in test, just how know discrimination.
Four, when code-disc speed is tested: generally use oscillograph directly to measure.Such test mode its essence is the spacing read before random two continuous code-disc signals in the code-disc signal, and this needs an oscillograph to complete.In addition, because the code-disc speed of cash inspecting machine when the actual operation is not an absolute fixed value, such test can only be measured the speed of the signal representative between these two signals, can not represent the average velocity of code-disc within a period of time, therefore the code-disc speed accuracy tested out like this is lower, is difficult to really obtain the real code-disc speed of financial utensil.
Five, when obtaining the program operation information: when the work of target finance utensil is undesired, the state that obtains the controller of current goal finance utensil inside is very valuable, these information can characterize the state of current controller, why help the developer to understand mistake can occur, perhaps reduce wrong scene (reappear the same mistake), thereby improve accordingly.Current, the operation information of the program that the developer will live must be downloaded emulation by special cable by the emulator that uses this control chip special use, reduce the processor information of wrong scene can gather wrong the generation time simultaneously, this operating efficiency is low, and operating personnel's Specialized Quality is had relatively high expectations, substantially do not possess such condition outside producer.
