Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention, as shown in Figure 1, the present invention is a kind of image collecting device that is used for score-clearing system, comprising: camera, sensor, synchronizing circuit, capture card, CPU and storer; And,
Described camera and described capture card are coupled; Described sensor is coupled by described synchronizing circuit and described capture card; Described capture card and described CPU are coupled; Described storer and described CPU are coupled;
What described sensor will be sensed is sent to described synchronizing circuit by sorting thing entering signal; Described synchronizing circuit sends synchronizing signal, and sends this synchronizing signal to described CPU through described capture card; Described CPU sends acquisition instructions through described capture card to described camera; Described camera sends the view data of gathering to described CPU through described capture card to by sorting thing continuous acquisition and generate view data; Described CPU handles described view data, deposits the view data after handling in described storer.
Be that example describes with a check score-clearing system below:
As shown in Figure 3, gathering visual equipment comprises: capture card, line-scan digital camera, synchronizing signal device.The process of its image acquisition is as follows:
When 1) check arrived sensor, synchronizing signal became high level, triggering collection.
2) synchronizing signal is kept high level, and camera continuous acquisition data are in buffer zone.
3) check is by behind the sensor, and synchronizing signal becomes low level, finishes the collection of a hardwood figure.
Wherein, the distance dependent between vertical resolution and camera and the cleaning-sorting machine track, the more little resolution of distance is high more.Horizontal resolution is relevant with the sweep velocity of camera.The resolution that sweep velocity (line/second)=orbital velocity (inch per second) * requires.Should make vertical consistently, guarantee that image can distortion with horizontal resolution.The size difference of check is provided with the acquisition buffer district according to the size of maximum check.
As shown in Figure 2, the system design ability is 1200DPM, and the processing time of every hardwood image is 50MS.The flow process of handling has 5 steps: gather, cut out, rotate, compress, store.The processing time of each step is all less than 50MS, but summation is greater than 50MS, so these 5 steps are arranged to a streamline.Each step all has the processing buffer zone of oneself, in circular treatment, takes out first pending image in the buffer zone successively, puts it into after disposing in the processing buffer zone of next procedure.These 5 steps show as 5 processing threads in program.
The processing speed of total system depends on the slowest step in 5 steps, but also relevant with the processing power of CPU.
The flow process of image program and sorting Program Synchronization is:
1) uses the TCP communication between sorting program and the visual program.
2) send serial number and time behind sorting programmed acquisition to a magnetic code to visual program.
3) visual program puts it into the serial number formation after receiving serial number.
4) visual programmed acquisition is behind a hardwood image, and taking out article one serial number from the serial number formation is the image name.
5) for preventing that image from losing, acquisition time and the difference of serial number time of image be foundation as a comparison, when current difference during greater than averaging time of preceding 20 hardwoods, thinks that image has taken place to be lost, and the transmission error message makes the cleaning-sorting machine shutdown to the sorting program.
6) when several checks connect together, might one the magnetic code data can a corresponding more than hardwood image, so need to shut down during the magnetic code overlength.
7) when the folder ticket, when losing situation such as image, need deletion magnetic code data so that magnetic code and image are corresponding one by one, the bill of deletion needs sorting again.
The circuit diagram of synchronizing circuit (synchronizing signal device) is seen accompanying drawing 4, wherein the major function of sensor signal time-delay synchronizing circuit plate is that the appropriate location is extracted and obtained sensor signal from the cleaning-sorting machine, through certain time-delay, image pick-up card is delivered in requirement according to signal level, for image acquisition provides synchronous.
Synchronizing circuit mainly is divided into three parts: the driving output of the generation of sensor signal, the time-delay of signal, signal.
The generation of sensor signal, i.e. JSENSOR interface in the circuit, the pin of this interface connects the anode and the negative electrode of infrared-emitting diode, and the collector and emitter of infrared reception triode.Infrared-emitting diode and reception triode are that pairing is used, and are installed in cleaning-sorting machine and run appropriate location on the ticket track, and the extraction output point of synchronizing signal SENSOR at pin 3..Under the normal condition, when promptly not having bill to pass through, the infrared light that infrared reception triode receives from emitting diode is in state of saturation, and this point is low level; When bill passed through, bill stopped infrared light, and this is a high level under the effect of pull-up resistor.The synchronizing signal high level lasting time equals the time of bill through the sensor acceptance point.
Because the synchronous signal sensor mounting points is subjected to the restriction of cleaning-sorting machine structure, can not be installed on the image acquisition point, can only be installed in the anticipated future position of image acquisition point, synchronous in order to guarantee the image acquisition zero hour and bill traveling process, need delay time to synchronizing signal.
The time-delay of signal realizes by singlechip chip, obtains SENOUT after sensor signal process Schmidt's phase inverter circuit U2A shaping and the paraphase, delivers to the pin 12 of single-chip microcomputer U1, through internal delay time, by the synchronizing signal SYNC after the pin 11 output time-delays.The single-chip microcomputer inner loop detects this pin 12, and when SENOUT was low level, single-chip microcomputer time-delay output SYNC signal was a low level; When SENOUT was high level, the SYNC signal was a high level.Rising edge and the negative edge of output synchronizing signal SYNC are respectively rising edge and the negative edge of signal SENOUT after constant time lag.The size of delay time is to determine that by the distance between the mounting points of sensor and the image acquisition point distance is long more, and the delay time that needs is long more.
For the image pick-up card that external synchronization signal is had the software delay function, can utilize its software delay function, at this moment, in this circuit, need with the JS interface pin 1., 2. through the jumper wire device short circuit.
The driving output of signal comprises that TTL (transistor-transistor logic) drives output, and LVDS (low-voltage differential signal) drives output.TTL drives output and is finished by U2B and U2C, exports through interface JHEADER3; LVDS drives output and is finished by differential signal chip for driving U3, through interface JOUT and JHEADER1 output.The selection of the synchronizing signal way of output is to determine that by the requirement of image pick-up card to synchronizing signal the image pick-up card of different company and brand requires different to the input mode of external synchronization signal.
The auxiliary circuit part:
Power input interface J1 provides power supply by the outside to the synchronizing signal plate;
The power supply indication is finished by LED 1;
The synchronizing signal indication is finished by LED 2;
Interface JAVRISP is a single-chip microcomputer run time version download interface.
The beneficial effects of the utility model are, by a kind of image collecting device that is used for score-clearing system is provided, provide the colored bill image of high-quality, high definition, for sorting provides convenience with the bill Flame Image Process.Simultaneously, equipment cost is lower, and is easy to utilize.
Above embodiment only is used to illustrate the present invention, but not is used to limit the present invention.
