Among the present invention, the time threshold of reservation can be determined according to the tag readable degree time of radio system.The tag readable degree time can be determined flexibly according to speed of production, the occupation area of equipment (affecting the device synchronization distance) of ticket and security printing equipment.
The below introduces operation logic and the concrete example of ticket online quality control equipment of the present invention in detail.
Fig. 3 has shown the ticket array schematic diagram of the specific embodiment of the invention.
In the large plate 16 of ticket as shown in Figure 3, ticket 17 arrays of exemplary employing 4 * 3, the direction of arrow is the moving direction of the large plate of ticket among Fig. 3.But, the present invention is not restricted to this, also can be according to actual conditions (for example, dissimilar bank's ticket, and the varying number of every edition ticket in the production process) radio frequency card reading module and radio-frequency antenna arrangement mode and quantity are set, as long as guarantee that arranging of radio frequency card reading module and radio-frequency antenna is identical with the ticket arrangement mode, the position is corresponding one by one.
Accordingly, the radio frequency card reading module and the radio-frequency antenna that arrange on the radio-frequency transmissions cylinder drive also are 4 * 3 arrangement, and the spacing of row and column and ticket corresponding spacing are consistent so that each ticket under correspondence a radio-frequency antenna 14 and radio frequency card reading module 15 are set.In the present embodiment, the length of transmission device is set to 30cm, is the tourelle power supply of radio-frequency transmissions cylinder by the 220V alternating current, adopt the brush mode to power take the 5V direct current as the radio frequency card reading module, but the present invention is not restricted to this.
In the present embodiment, the print speed printing speed s that supposes bank's ticket is 200-300cm/s, the short label recognition time t of radio system
0Be 100 milliseconds, can be by the shortest synchronic distance l of calculative determination transmission device and printing machine
0, synchronic distance l
0Be radio-frequency antenna and the distance of corresponding ticket along the ticket direction of advance, with the time of the reading t long enough of the reality that guarantees the radio frequency card reading module, namely at least greater than short label recognition time t
0Specifically, synchronic distance l equal print speed printing speed s and read the product of time t (l=s * t), corresponding, the shortest synchronic distance l
0Equal print speed printing speed s and short label recognition time t
0Product (l
0=s * t
0).Therefore, in the situation that tag readable degree time t is constant, synchronic distance l is determined by print speed printing speed s.
Based on the above-mentioned relation formula, when print speed printing speed s is 300cm/s, the short label recognition time t of radio system
0When being 100 milliseconds, calculate the shortest synchronic distance l of emission rotor drive
0Be 30cm.In addition, when print speed printing speed<300cm, if synchronic distance still is 30cm, the tag readable degree time can prolong, but does not affect printing process.When print speed printing speed>300cm, then synchronic distance needs corresponding increase to adapt to new print speed printing speed.
At present, the print speed printing speed of existing ticket and security printing machine can not surpass 300cm/s usually, and still, along with technological progress, this speed may have continuous lifting.Simultaneously, because the long meeting of synchronic distance causes the ticket and security printing occupation area of equipment to increase, time and the distance also corresponding increase of ticket on production line.

Step S105, if the identification signal of not receiving, main control unit judges whether recognition time surpasses scheduled time threshold value.
Main control unit with the time point of ticket and the contact of corresponding radio-frequency antenna as time zero, if main control unit does not receive the ticket identification signal that radio-frequency antenna returns from the radio frequency card reading module, the time that main control unit can be judged the identification ticket, whether (this time threshold was usually very short above scheduled time threshold value, for example 100 milliseconds), if do not surpass this time threshold, main control unit can continue to wait for that the radio frequency card reading module sends identification signal, until receive identification signal in this time threshold, perhaps recognition time surpasses this time threshold.
Step S106, if recognition time surpasses scheduled time threshold value, main control unit is regarded as the problem ticket with ticket.
After recognition time surpassed scheduled time threshold value, when main control unit did not still receive the ticket identification signal from the radio frequency card reading module, main control unit assert that the label in this ticket is invalid, and it is considered as the problem ticket.
Step S107 obtains the positional information of problem ticket.
To there being the electronic bill of quality problems, main control unit obtains the positional information of this ticket by the light sensation device.
Step S108 is to problem ticket ink-jet mark.
Main control unit sends the ink-jet instruction based on the positional information of the problem ticket that obtains to ink discharge device, starts the jet orifice corresponding with this ticket, ink discharge device by inkjet mouth to unidentified to the problem ticket carry out ink-jet marking.
So far, finish the online testing process to ticket, for normal ticket, equipment carries out initialization process, and for the problem ticket, equipment will carry out the ink-jet mark, so that subsequent treatment.
