Description

LCD or television set automatically resetting factory settings device and method

[technical field]

The utility model relates to display and television set production line detection range, specifically is meant LCD (liquid crystal) display or television set automatically resetting factory settings devices and methods therefor.

[background technology]

In the procedure for producing of LCD display and television set, be in the optimum state of an acquiescence in order to allow product in arriving user's hand the time, must carry out the action of factory reset.Generally speaking, this action is the button by every display of manual operation or television set, accesses its inner OSD (OnScreen Display) menu, selects " factory reset " also affirmation, recovers the Default Value of display or television set.Whole process steps is many, spended time is long and have the operation leakage.

[summary of the invention]

One of technical problem to be solved by this invention be for LCD or television set provide a kind of anti inert, automatically, automatically resetting factory settings device cheaply.

Two of technical problem to be solved by this invention be for LCD or television set provide a kind of anti inert, automatically, automatically resetting factory settings method cheaply.

The present invention one of solves the problems of the technologies described above by the following technical solutions:

LCD or television set automatically resetting factory settings device comprise IIC communication module, single-chip microcomputer, line body PLC control module, peripheral hardware control module; Wherein said IIC communication module, described line body PLC control module, described peripheral hardware control module all are connected with described single-chip microcomputer; Described IIC communication module is connected with LCD that needs factory reset or television set; One video signal generator is connected with described IIC communication module; Described line body PLC control module is connected with line body PLC.

The present invention adopt that following technical scheme solves the problems of the technologies described above two:

LCD or television set automatically resetting factory settings method comprise the steps:

Step 100: beginning;

Step 101: initialization external equipment;

Step 102: the display of connection or TV are arranged on the signal lines? be, change step 103 over to, not, continue to detect;

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

Step 104: the recovery order is set by the transmission of IIC agreement;

Step 105: judge whether display or TV have recovered to be provided with? be to change step 106 over to; , do not change step 107 over to;

Step 106: send the departures order to line body PLC, change step 102 over to;

Step 107: report to the police and the demonstration error message, change step 102 over to.

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

The advantage of LCD of the present invention or television set automatically resetting factory settings devices and methods therefor is: by the IIC communications protocol, automatically call 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 unusual, guaranteeing does not have leakage.

[embodiment]

See also shown in Figure 1ly, LCD or television set automatically resetting factory settings 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 all are connected with single-chip microcomputer; The IIC communication module is connected with LCD that needs factory reset or television set; The IIC communication module also is connected with video signal generator; Line body PLC control module is connected with line body PLC.

Please consulting Fig. 2 to Fig. 6 simultaneously, is each module hardware conspectus among the present invention.

Single-chip microcomputer: single-chip microcomputer is based on the enhancement mode single-chip microcomputer of any model 8051 kernels, and the compiled software of its operation preliminary election is finished the function of software appointment by the I/O pin of single-chip microcomputer, as the communication of above-mentioned IIC communication, peripheral hardware control, line body PLC etc.It is the carrier of software, and major function is embodied on the algorithm of software.

The IIC communication module: circuit is converted to 2 the tunnel by electronic switch U101 (CD4052 or similar model) with one road IIC communication output, can realize the asynchronous operation of 2 products simultaneously.

Line body PLC control module: form one group of K switch 100, K101, one group of K102, K103, the PLC control of each corresponding 1 product by 4 groups of switches.Work as K100, when K101 was closed, control PLC stopper descended, K102, K103 function unanimity, and they are controlled by single-chip microcomputer.

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

The course of work: after product flows into and specifies erect-position, blocked by line body PLC resistance frequency modulator, product can not flow to next processing procedure; Operator connects the product signal line, and video signal generator provides a vision signal that product is operated under the normal condition.Hardware is with whether machine is arranged on the automatic detection signal line at this moment, if having, each order and relevant parameter that the IIC communication module in the hardware will be imported by peripheral hardware in advance send product to, control the action that product is finished factory reset automatically; After finishing the action of factory reset, line body PLC control module sends a short-circuit signal (K100～K104 closure) to line body PLC, after line body PLC receives this signal, the control stopper descends, machine flows out erect-position voluntarily, and operator is pulled out holding wire, and the operation action is finished.

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

Step 100: beginning;

Step 101: initialization external equipment;

Does step 102: detecting have the display of connection or TV on first holding wire? be, change step 103 over to, not, change step 109 over to;

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

Step 104: the recovery order is set by the transmission of IIC agreement;

Step 106: send the departures order to line body PLC;

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

Is step 108: detecting first holding wire to disconnect with being connected of display or TV? be, change step 102 over to, not, continue to detect;

Does step 109: detecting have the display of connection or TV on second holding wire? be, change step 110 over to, not, change step 102 over to;

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

Step 111: the recovery order is set by the transmission of IIC agreement;

Step 112: judge whether display or TV have recovered to be provided with? be to change step 113 over to; , do not change step 114 over to;

Step 113: send the departures order to line body PLC;

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

Is step 115: detecting second holding wire to disconnect with being connected of display or TV? be, change step 102 over to, not, continue to detect;

The present invention can be embedded in the control system of production line, realizes that Default Value recovers the fool proof of 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 unusual, guaranteeing does not have leakage.
