There are a lot of drawbacks in this testing scheme.Need change the complete machine of respective model when testing the DVD-P/DVD-R front panel of different model, make and use complete machine not possess versatility, increase the complicacy of operation process, increase cost of manufacture simultaneously as proving installation; In addition, because starting when moving, DVD-P/DVD-R need be written into the time, so this scheme operating efficiency is lower.
Summary of the invention
For addressing the above problem, the present invention proposes a kind of general DVD-P/DVD-R front panel proving installation, comprises power supply and master chip, reset key, crystal oscillator and pilot lamp, wherein:
Master chip is connected with described power supply, is used for control, judgement and test transmission information;
Reset key is connected with described master chip, is used to proving installation that reset signal is provided;
Crystal oscillator is connected with described master chip, and the clock frequency that provides described proving installation required is provided;
Pilot lamp is connected with described master chip, is used for display power supply state and test mode.
Described master chip can be a single-chip microcomputer, and described crystal oscillator is preferably the clock frequency that described proving installation provides 12MHz, and described pilot lamp can be a laser diode.
The present invention proposes a kind of general DVD-P/DVD-R front panel method of testing simultaneously, and it may further comprise the steps:
The DVD-P/DVD-R front panel of need test is connected to general DVD-P/DVD-R front panel proving installation;
Be sent to the master chip of general DVD-P/DVD-R front panel proving installation after the key information of this DVD-P/DVD-R front panel is encoded;
Can described master chip be judged and be discerned the described coded message that receives;
If can not discern, then described master chip sends to the DVD-P/DVD-R front panel with error message, and shows test errors by the pilot lamp of general DVD-P/DVD-R front panel proving installation;
If can discern, be transferred to the DVD-P/DVD-R front panel after then described master chip is deciphered coded message and show.
General DVD-P/DVD-R front panel proving installation of the present invention and method of testing have used MCU (micro-control unit) to replace original complete machine, and the original test of simulation machine performance, saved testing cost, improve the versatility of proving installation, and improved testing efficiency to a great extent.

Embodiment
Below in conjunction with accompanying drawing to a preferred embodiment of the present invention will be described in detail.
Fig. 1 is present DVD-P/DVD-R front panel proving installation.As shown in the figure, in this scheme, the DVD-P/DVD-R front panel need be installed on the new DVD-P/DVD-R test complete machine and test.
Fig. 2 is the general DVD-P/DVD-R front panel proving installation of the preferred embodiment of the present invention.
As shown in the figure, the general DVD-P/DVD-R front panel proving installation of present embodiment comprises power supply, master chip, reset key, crystal oscillator and pilot lamp.Wherein pilot lamp has adopted laser diode.
Power unit offers proving installation with the 220V voltage transitions for 5V voltage.Master chip adopts functions such as chip microcontroller data processing and control.If situations such as instability appear in master chip, can provide reset signal for master chip by reset key, rerun so that start master chip.
Pilot lamp comprises the laser diode that is used for the display power supply state and is used to indicate the laser diode of test errors.When proving installation was powered on, the laser diode that is used for the display power supply state lighted.
Crystal oscillator provides the clock frequency of 12MHz for master chip.
Need the DVD-P/DVD-R front panel of test to comprise LED, led driver and button.Wherein, LED is used for display button information, and for example when the information of pushing button was the button of " 1 ", LED just showed " 1 ".Led driver is used for driving LED, is used to scan key information simultaneously, and carries out communicating by letter of detecting information with the system master chip.
Fig. 3 is the general DVD-P/DVD-R front panel proving installation course of work process flow diagram of the preferred embodiment of the present invention.
As shown in the figure, the beginning step is connected to general DVD-P/DVD-R front panel proving installation for the front panel that will test; In the S1 step, the key information that button sends is transferred in the led driver; In the S2 step, led driver is delivered to master chip after the key information of receiving is encoded; In the S3 step, can master chip be judged and be discerned the coded message that receives; If can not discern, then enter the S4 step, master chip sends to led driver and pilot lamp with error message, in the S5 step, is used to indicate the lamp of test errors to light in the pilot lamp subsequently; Enter the S6 step after the S5 step, master chip is transferred to led driver after coded message is deciphered, and if in the S3 step master chip can discern the coded signal that receives and also enter the S6 step; The S7 step is that led driver is converted to display message to the decoding information that receives, and shows by LED; Finish subsequently.
