Embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
Fig. 1 shows the process flow diagram of the Detection of Stability method of the mechanical platform for print system according to the embodiment of the present invention, comprising:
Step S10, driving device platform transmits stock;
Step S20, detects multiple marks of stock continuously;
Step S30, to the mistiming timing detected between multiple mark;
Step S40, according to the length between timing and multiple mark, determines the actual speed of mechanical platform, and such as, V=Δ S/ Δ T, V is actual speed, and Δ S is the length between two marks, and Δ T detects the mistiming between two marks.
Namely this method judges by the mode detecting the same distance paper feed time used the steadiness that mechanical platform runs.This method, by detecting the mark of stock, solves the test problems of mechanical platform stability in print system, thus has stopped the phenomenon such as (the inaccurate position of cover), ghost image that walks, and improves printing quality.
Preferably, stock is continuous paper, is designated the colour code on continuous paper, adopts color mark sensor to detect colour code.When print system adopts continuous-forms printing, continuous form has printed colour code, and the distance between every two colour codes is equal.Therefore utilize colour code to judge the stability that mechanical platform runs, simple.
Preferably, stock is sheet-fed, is designated two edges of sheet-fed, adopts optical trigger Edge detected.When print system adopts sheet-fed to print, the length of every page of paper is equal, and for the detection of sheet-fed platform, namely measuring table runs the sheet-fed length time used.The program is simple.
Preferably, when adopting counter counts.When mechanical platform runs with a certain speed, after pick-up unit samples useful signal, start counting unit and start counting, after again sampling useful signal, counting unit stops counting.The value that now counting unit obtains is mechanical platform running the paper feed time in a certain distance, so just can assess the steadiness of this mechanical platform under a certain speed by obtaining multiple paper feed time.
Preferably, driving device platform transmits stock with setting speed, and method also comprises: if determine that actual speed is not equal to setting speed, then adjust the transfer rate of mechanical platform, make actual speed equal setting speed.This preferred embodiment achieves the automatic adjustment of the transfer rate to mechanical platform, alleviates the burden of operating personnel.
Fig. 2 shows according to the preferred embodiment of the invention for the process flow diagram of the Detection of Stability method of the mechanical platform of print system, comprises the following steps:
Step S100, runs mechanical platform with a certain speed;
Step S101, detects useful signal, and when mechanical platform adopts continuous paper, useful signal is the colour code on continuous paper, and when mechanical platform adopts sheet-fed, useful signal is two margin signals of sheet-fed;
Step S102, calculates from detecting that a useful signal is to the time that next useful signal is used being detected, and namely mechanical platform runs the time that regular length needs, and along with mechanical platform continuous service, will obtain a series of time value;
Step S103, compares analysis to the time value obtained, and the steadiness of Evaluation Platform under this speed accordingly.
Fig. 3 shows the schematic diagram of the stability detector of the mechanical platform for print system according to the embodiment of the present invention, comprising:
Driver module 10, transmits stock for driving device platform;
Detection module 20, for detecting multiple marks of stock continuously;

Preferably, stock is continuous paper, is designated the colour code on continuous paper, and detection module 20 comprises color mark sensor, for detecting colour code.
Preferably, stock is sheet-fed, and be designated two edges of sheet-fed, detection module 20 comprises optical trigger, for Edge detected.
Preferably, timing module 30 comprises counter, for timing.When detection module samples mark, send signal and notify that corresponding counter starts or stops counting.Altogether can arrange three counters, wherein two counters are used for continuous paper detection module, and another one counter is used for sheet-fed detecting pattern.When mechanical platform adopts continuous paper, use two counters, because the counter at counting colour code interval, after sampling first Color mark signal, start counting, counting is stopped when adopting second Color mark signal, now, when second Color mark signal arrives, represent that next interval starts, but untreated due to a upper Counter Value, the above counter of institute is in down state, in order to not lose interval data, be provided with counter 2, counter 1 and counter 2 use in turn.And when adopting sheet-fed, then only need employing counter because there is certain distance between paper, counter have after completing once counting time enough start on once count.
Preferably, driver module 10 transmits stock for driving device platform with setting speed, and device also comprises: adjusting module, if for determining that actual speed is not equal to setting speed, then adjust the transfer rate of mechanical platform, makes actual speed equal setting speed.
In the middle of practice, can driver module 10, timing module 30, determination module 40 and adjusting module 50 be integrated in a controller, this controller can adopt FPGA (FieldProgrammableGateArray, field programmable gate array) to realize.Selection module can also be comprised in FPGA inside, walk sheet type, continuous paper or sheet-fed for what select mechanical platform, then determine corresponding detecting pattern.
As can be seen from the above description, the above embodiments of the present invention can analyze the steadiness of mechanical platform under certain command speed in print system simply, rapidly, and the stability difference situation under different travelling speed, location can also be helped and analyze picture quality Problems existing in print procedure.
