Abstract

The utility model relates to an automatic factory settings recovery device for a liquid crystal display or a television, which comprises an IIC communication module, a singlechip, a line PLC control module and a peripheral control module, wherein the IIC communication module, the line PLC control module and the peripheral control module are all connected with the singlechip; the IIC communication module is connected with the liquid crystal display or the television whose factory settings need to be recovered; a video signal generator is connected with the IIC communication module; and the line PLC control module is connected with a line PLC phase. The automatic factory settings recovery device automatically calls the product factory settings recovery function, combines the line PLC blocking function and transforms steps required by the manual operation into a mode of instruction execution to realize automation by an IIC communication protocol. By automatically detecting signal plugging, the automatic factory settings recovery device guarantees the display or the television to 100% take the motion of recovering the factory settings. When the abnormal phenomena occur, the automatic factory settings recovery device guarantees no loss.

Description

LCD or television set automatically resetting factory settings device

[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 device.

[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.

[utility model content]

Technical problem to be solved in the utility model be for LCD or television set provide a kind of anti inert, automatically, automatically resetting factory settings device cheaply.

The utility model 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 advantage of the utility model LCD or television set automatically resetting factory settings device 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 in the utility model.

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.

The utility model 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.
