Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conveyed object monitoring and discrimination method for conveying paper leaf-like objects such as banknotes and identifying them while monitoring the conveyance state.
This is to obtain iWiL.

In general, in this type of conveyed object monitoring and discrimination system, such as a banknote discrimination device, monitoring of the conveyance state of a paper sheet-shaped conveyed object, discrimination of the conveyed object, and output of the discrimination result, that is, opening of an interface with an external device, is performed. Conventionally, a single processor or a device with similar functionality was used to perform these opening operations. However, in such conventional methods, these opening operations have to be performed sequentially in chronological order, so the conveyance of the paper sheet-like object is performed continuously at high speed, and the interface with external equipment is irregular. I was forced to do INK9
In principle, a single processor cannot handle such a situation, for example, when a subsequent conveyed object must be identified at the same time as the identification result of the preceding conveyed object is output to an external device. 9,
Therefore, there is a drawback that the speed of transporting objects and the speed of processing identification results are limited by the processing capacity of the processor.

An object of the present invention is to eliminate the above-mentioned conventional drawbacks, and to monitor the conveyance state of a conveyed object, identify the conveyed object, and open an interface with an external device in response to the discrimination results independently of each other. It is an object of the present invention to provide a conveyed object monitoring and identification system that operates in a manner compatible with the above requirements.

That is, the monitoring and identification method of the present invention processes data detected regarding a plurality of continuously transported objects by multiple processors separately, thereby monitoring the transport state of the objects and identifying the objects. The present invention is characterized in that the interfaces for the identification results and the external devices are connected to each other so that they can be shared.

The present invention will be described in detail below with reference to the drawings.

An example of the circuit configuration of the conveyed object monitoring and identification device O according to the method of the present invention is shown in No. 1m, and an example of the configuration arrangement of the monitoring and identification section is shown in No. 2@I.
Show K. In the circuit configuration shown in tfg, the processor l
is used to interface with an external device (not shown) and monitor the conveyance status of the conveyed object.
The processor identifies the conveyed object and checks the operation of the entire apparatus based on instructions from the processor l. These processors 1 and 3 are, respectively,
Data is mutually transferred in both directions via ports 3 and j, and each has separate random access memories 3 and 3.

Therefore, as mentioned above, with a single processor,
Alternatively, there is no memory access conflict unlike in conventional devices equipped with only a single memory device, and various data processes can be smoothly performed at high speed. However, on the other hand, since the processors I and Hiroshi can operate independently of each other, the system basically operates asynchronously, and there is a risk that the system will go down.

Therefore, in the monitoring and discrimination method of the present invention, the processor l that interfaces with external devices and monitors the conveyance state is the upper processor, and the processor l that discriminates the conveyed object is the lower processor, and by positioning the respective processors, This prevents the occurrence of a system down due to the above-mentioned asynchronous operation, avoids competition between the processors 1 and 2, eliminates the disadvantages of the multiprocessor system, and promotes only the advantages of high-speed data processing.

Next, the basic operation of the conveyed object monitoring and discrimination method according to the method of the present invention will be explained.

As mentioned above, the monitoring and discrimination method of the present invention basically operates asynchronously as a system, but when the system starts operating when the power is turned on, there is a difference! /&Processor l at the time of restarting operation by Th9 set.

Since it is necessary to synchronize only for the rise of the peak,
In order to synchronize the initial operation, initial operation communication as shown in FIG. 3 is performed. That is, at the start of the initial operation, first, a signal is sent from the upper processor to the bidirectional path.
'91', and then the signal X't'
Wait until it is sent and returned. On the other hand, upon detecting the signal X'9t' from the processor l, the lower-level buseser-tei immediately transmits the signal X'91' to the processor l.
/ and then sends the next signal x'yy
Wait until ' is transmitted. Then, Pl11-
Is the signal X'? When it is confirmed that r' has been sent and returned, the next signal XIF' is sent to the bidirectional path to complete the initial operation, and the state remains in the initial loop state of P level until an operation command is received from the external device. Become. On the other hand, when the processor confirms that the next signal Until an operation command is received from the processor I, the same initial loop error occurs at the P level.

Then, when the actual monitoring and discrimination operation begins (9), the operation command from the external device is notified to the processor 1 through interrupt processing, so the processor 1 shifts to the interrupt level state. In this interrupt level state, the upper processor I performs its own data processing operation in accordance with the command data O output from the external device to the Inter7 Ace bus. Notify operation command to processor #. Such a processor
The notification of operation commands from the processor to the processor is also notified by the embedding process, so the processor is notified.

Similarly, in the interrupt level state, depending on the contents of the command data output from processor l to the bidirectional bus,
The system branches to each assigned operation mode, and then repeats the above-mentioned mental movement process to perform a predetermined monitoring and discrimination operation.

Next, to explain the basic operations of the processor 1 and processor 1 in the discrimination operation mode for paper as a conveyed object that is being conveyed continuously, the conveyance state of the banknote that is being conveyed is monitored as shown in FIG. The banknotes are discriminated based on the detection output signals of the monitoring sensors St-S distributed on the conveyance path X, and a plurality of discrimination sensors Is distributed on the conveyance path It is performed by the combination K of the detection output signals from / ~ engineering St. These monitoring and discrimination sensors, for example, use 7 sensors to monitor the conveyance state of the banknotes, or
Distributing and distributing banknotes at appropriate positions for different purposes.

In the banknote discrimination mode, the upper processor/ sends the detection output signals of the monitoring sensor 8/ and Sr, 39 through the inverter// and the Nantes gate/3, respectively.
The banknotes are constantly accepted through the input/output port, and in order to monitor the conveyance status of banknotes, the distance between the banknotes being continuously conveyed is measured. In other words, the preceding banknote is the monitoring sensor 'V''
By measuring the elapsed time to determine how far the subsequent banknotes have been conveyed since they entered the position of the monitoring sensor Sl at the time when they passed through the sr and svo positions, the continuously conveyed banknotes can be measured. Constantly measure the mutual spacing between.

On the other hand, the lower processors are the monitoring sensor S, S3
From the moment the bill enters the monitoring sensor Si! , the period up to the time when the position of S7 is passed is calculated by the sensors S, 83 and 84, 87
Detection output signals received from the input/output boat j via the Nant gates /f and /3, respectively, and the detection output from the monitoring sensor S/ via the input/output boat j via the inverter l. Detected by signal. During this period, the detection output signals of the patterns on the banknote surface obtained simultaneously from each of the identification sensors Is/-IS4 are read from the amplifier group into the random access memory/σ via the analog-to-digital converter GSL. Based on the read output from the random access memory/σ, the type, authenticity, etc. of the banknote are identified. Then, at the time when the bill passes through the monitoring sensors Sa and Sγ, the processor S/K transmits the result of the discrimination to the upper processor S/K, and the processor S/K transmits the data of the discrimination result and the above-mentioned bill. Banknote discrimination information is finally created based on the data of the mutual distance measurement results, and is reported to an external device after a certain period of time has elapsed since the banknote passed through the monitoring sensors sr and sde at the final position.

In addition, the position, number, etc. of each sensor in the above-mentioned example of the configuration and arrangement can be appropriately changed and set arbitrarily according to the shape, size, pattern, etc. of the banknote to be discriminated, that is, the conveyed object. In addition, each of the above-mentioned operations is controlled by timing pulse generation @7 connected to processor #.

As is clear from the above description, according to the present invention, when monitoring the conveying state of conveyed objects in the form of banknotes and identifying the objects, high-speed processing that cannot be processed by a single processor is It is possible to reliably and easily identify the type of a conveyed object that is continuously conveyed at a high speed, and accurately monitor any interface with an external device and the conveyance state. Note that such effects are not limited to the above-mentioned example of banknotes, but can also be obtained in the same way when monitoring and identifying conveyed objects in the form of paper sheets that are inserted in batches and conveyed at high speed.
