Step 100: start;

Step 101: initialization external equipment;

Step 102: have the display of connection or TV in signal lines? be, proceed to step 103, no, continue to detect;

Step 103: gating iic bus, to holding wire, connects communication loop;

Step 104: send to arrange by IIC agreement and recover order;

Step 105: judge whether display or TV have recovered to arrange? to proceed to step 106; No, proceed to step 107;

Step 106: send departures order to line body PLC, proceed to step 102;

Step 107: reporting to the police and showing error message proceeds to step 102.

As a further improvement on the present invention, in described step 102, holding wire is two.

The advantage of liquid crystal display of the present invention or television set automatic factory settings recovery device and method thereof is: by IIC communications protocol, Automatically invoked product factory reset function, and joint line body PLC barrier functionality, reach the step that manual operation is needed and be converted into the form that instruction is carried out, to realize automation.By automatic detection signal, plug, guarantee that display or television set 100% do the action of factory reset.Occur when abnormal, guarantee without leakage.

[embodiment]

Refer to shown in Fig. 1, liquid crystal display or television set automatic factory settings recovery device, comprise IIC communication module, single-chip microcomputer, line body PLC control module, peripheral hardware control module; Wherein IIC communication module, line body PLC control module, peripheral hardware control module are all connected with single-chip microcomputer; IIC communication module is connected with needing liquid crystal display or the television set of factory reset; IIC communication module is also connected with video signal generator; Line body PLC control module is connected with line body PLC.

Please refer to Fig. 2 to Fig. 6, it is each module hardware conspectus in the present invention.

Single-chip microcomputer: single-chip microcomputer be take the Strong MCU of any model 8051 kernels as main, the compiled software of its operation preliminary election, completes the function of software appointment by the I/O pin of single-chip microcomputer, as above-mentioned IIC communication, peripheral hardware are controlled, the communication of line body PLC etc.It is the carrier of software, and major function is embodied on the algorithm of software.

IIC communication module: circuit is by electronic switch U101 (CD4052 or similar model), and Jiang Yi road IIC communication output is converted to 2 tunnels, can realize the asynchronous operation of 2 products simultaneously.

Line body PLC control module: by 4 groups of switches, formed, mono-group of K switch 100, K101, mono-group of K102, K103, the PLC of each corresponding 1 product controls.Work as K100, when K101 is closed, control PLC stopper declines, and K102, K103 function are consistent, and they are controlled by single-chip microcomputer.

Peripheral hardware control module: be a LCDs (LCD101), possess keyboard and screen, be directly connected with single-chip processor i/o.U105 (74LS05) will send into single-chip microcomputer analysis after keyboard signal separation buffering, to show or to obtain the data of outside input.

The course of work: product flows into specifies after erect-position, is blocked by line body PLC resistance frequency modulator, and product can not flow to next processing procedure; Operator connects product signal line, and video signal generator provides a vision signal to make product work under normal condition.Now hardware is by whether there being machine on automatic detection signal line, if had, the IIC communication module in hardware sends each order and the relevant parameter by peripheral hardware, inputted in advance to product, automatically controls the action that product completes factory reset; Complete after the action of factory reset, line body PLC control module sends a short-circuit signal (K100～K104 is closed) to line body PLC, and line body PLC receives after this signal, control stopper declines, machine flows out erect-position voluntarily, and operator is pulled out holding wire, and operation has been moved.

Concrete software execution flow journey figure as shown in Figure 3.Detailed step is as follows:

Step 100: start;

Step 101: initialization external equipment;

Step 102: detect and have the display of connection or TV on first holding wire? be, proceed to step 103, no, proceed to step 109;

Step 103: gating iic bus, to holding wire, connects communication loop;

Step 104: send to arrange by IIC agreement and recover order;

Step 105: judge whether display or TV have recovered to arrange? to proceed to step 106; No, proceed to step 107;

Step 106: send departures order to line body PLC;

Step 107: report to the police and show error message;

Step 108: detecting first holding wire is to disconnect with being connected of display or TV? be, proceed to step 102, no, continue to detect;

Step 109: detect and have the display of connection or TV on second holding wire? be, proceed to step 110, no, proceed to step 102;

Step 110: gating iic bus to the second holding wire, connects communication loop;

Step 111: send to arrange by IIC agreement and recover order;

Step 112: judge whether display or TV have recovered to arrange? to proceed to step 113; No, proceed to step 114;

Step 113: send departures order to line body PLC;

Step 114: report to the police and show error message;

Step 115: detecting second holding wire is to disconnect with being connected of display or TV? be, proceed to step 102, no, continue to detect;

The present invention can be embedded in the control system of production line, realizes the fool proof that Default Value recovers action, avoids leakage.The step that manual operation is needed is converted into the form that instruction is carried out, to realize automation.By automatic detection signal, plug, guarantee that display or television set 100% do the action of factory reset.Occur when abnormal, guarantee without leakage.
