Description
Technical field
The present invention relates to a kind of circuit that opens a position fast, particularly a kind of realization disc player circuit that opens a position fast.
Background technology:
At present, the disc player circuit on the market is generally by master control system, form from control system, disc loading device and other control modules.Disc loading device is generally by the communication that links to each other with master control system of SATA (full name is a Serial Advanced Technology Attachment Serial Advanced Technology Attachment, a kind of serial hardware driver interface based on industry standard) or other signal buss.Master control system possesses the encoding and decoding of audio-video signal and format conversion output, user interface show and the user operates functions such as response.So the whole software systematic comparison complexity of master control system, initialization procedure is relatively slow, and particularly some built-in Linuxes or Windows Mobile, Android system generally can need tens seconds even just can finish for tens seconds the initialization of system.
Disc player generally comprises two kinds of duties: a kind of duty is a holding state, under holding state, master control system, disc loading device etc. all non-transformer are supplied with, system has only the unit (as from control system) of few part in work, realizes low-power consumption standby; Another kind of duty is an open state, this state master control system, and nearly all unit such as disc loading device is operate as normal all.When disc player response user's dependent instruction, change open state into by holding state after, by number control signal power circuit being powered from control system needs the element circuit of power supply to master control system and disc loading device etc.Disc loading device has been finished initialization (being generally less than 3 seconds) soon because the systematic comparison of itself is simple; But master control system is because above-mentioned complicacy causes the initialization time of master control system longer.In the initialization procedure of master control system, disc loading device can be in uncontrolled state, and the user can not outwards export (abbreviate as and open a position) or inwardly input (abbreviate as and close the storehouse) by the pallet of telepilot or face control plate respective keys control disc loading device.
The drawback of technology existence now is: after the operator must wait for that the startup of disc player master control system finishes, could open a position and close the storehouse disc loading device and operate, not have to carry out simultaneously the function of master control system initialization and warehouse entry.Start to video disc from disc player and load during this period of time,, lose time man-machine interaction friendliness extreme difference for the operator.
Summary of the invention:
The objective of the invention is to overcome the deficiencies in the prior art, a kind of circuit that opens a position fast that is applied to disc player is provided, when the disc player master control system starts, realize the operation that opens a position disc loading device.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of realization disc player method that opens a position fast, step is as follows:
(1) disc player holding state, the operator presses telepilot related key or face control plate related key, perhaps by the control mode of manually starting shooting, sends the start and the instruction that opens a position to disc player;
(2) order from control system response of step (1) is that each circuit power such as disc loading device, master control system power up, and each functional circuit starts;
(3) disc loading device sends the control command that opens a position from control system to disc loading device after finishing initialization;
(4) disc loading device responds the order that opens a position of sending from control system, carries out the operation that opens a position;
(5) operator loads video disc to the pallet of disc loading device, finishes video disc and loads action;
(6) operator sends and closes the storehouse instruction, and the storehouse instruction is closed in the disc player response, and disc loading device reads in advance to the video disc that the operator loads, and finishes the loading work of video disc in advance;
(7) treat that the master control system initialization is finished after, can directly carry out exchanges data with disc loading device, simultaneously, the operator opens a position and master control system response and execution are transferred in the instruction of closing the storehouse;
(8) before master control system is finished initialization, can respond the operation that repeatedly opens a position and close the storehouse from control system, also can be at the video disc in this stage replacing disc loading device.
A kind of circuit that opens a position fast of using the method that opens a position fast comprises master control system, from control system, disc loading device and control circuit.Interconnect by SATA between master control system and disc loading device, from passing through the RS232 (abbreviation of Recommended Standard between control system and master control system, proposed standard, 232 is identification number, being one of communication interface on the personal computer) serial ports carries out communication, or other modes, as I2C, SPI (abbreviation of Serial Peripheral Interface, Serial Peripheral Interface) etc.Link to each other by control bus (single or many control signal wires) between control system and the disc loading device.In the master control system initialization imperfect tense, by from control system control disc loading device switch storehouse, after the master control system initialization is finished, the disc loading device control is delivered master control system.
Compared with prior art, the invention has the beneficial effects as follows: except master control system that disc player possessed with bus between disc loading device is connected, be used to control the disc loading device He Guancang that opens a position from increasing by one group of control line between control system and disc loading device, can break away from master control system from control system works independently, scope and function have been enlarged from control system, in the master control system initialization procedure, disc loading device just can be accepted the control from control system, the operator can put into video disc in advance, allows disc loading device work in advance; Master control system can obtain information and begin the broadcast of video disc content after finishing initialization from disc loading device.Optimize the start of player and play the video disc flow process, saved the stand-by period, effectively realized human-computer interaction.
Description of drawings:
Fig. 1 is the disc loading device control flow from control system of the present invention;
Fig. 2 is a whole theory diagram of the present invention;
Fig. 3 is a master control system of the present invention and from the control system circuit diagram;
