The output of the multipath relay circuit is connected with a liquid crystal display module to be detected. Compared with a product in the prior, the detecting system has beneficial effects of a simple structure, easy detection, and automatic control of multiple powers of the liquid crystal display module achieved just by one button under the control of the 51 single chip microcomputer.
Description
Technical field
The utility model relates to a kind of one-touch automatic control multivoltage liquid crystal display module detecting system, can be widely used in the detection of each liquid crystal display module.Whether the quality that both can be applicable to liquid crystal display module manufacturing enterprise testing product before product export reaches requirement, also can be used as the enterprise of extensive application liquid crystal display module as the basis for estimation of product supplied materials quality.
Background technology
Inner in each liquid crystal display module manufacturing enterprise, no matter be the online detection on the production line, or the final detection before product export, all need quality to product whether to reach requirement and carry out strict differentiation.And on machine, equipment, instrument, instrument as human-computer interaction interface, widely apply the enterprise of liquid crystal display module, when the product supplied materials, often also to the requirement whether product meets application be detected.
For some fairly simple products, testing circuit or test condition are often also fairly simple.After powering up, write different test datas to the inside with single-chip microcomputer, just can realize the detection of indices.But a kind of outside module that the VLCD high voltage supply is provided that needs is arranged, and simple going detected like this.
This module has strict requirement to electric sequence and the power down sequence of each road voltage.Their VLCD module voltage not only requires the outside to provide, and when powering on, also need to just can provide this voltage after other power supply of module has all been stablized in time, and is then just in time opposite during outage.Detection to this series products is the difficult problem of industry, and especially in the production run of product, former detection method often causes a large amount of artificial damages to product in testing process.
Summary of the invention
The purpose of this utility model provides a kind of one-touch automatic control multivoltage liquid crystal display module detecting system, and this system architecture is simple, and is easy to detect, only with a button, under 51 Single-chip Controlling, realizes the automatic control of liquid crystal display module multiple power supplies.
For achieving the above object, the utility model is achieved through the following technical solutions:
One-touch automatic control multivoltage liquid crystal display module detecting system, comprise single-chip computer control system, power-switching circuit, multicircuit relay circuit, described single-chip computer control system is connected with power-switching circuit, multicircuit relay circuit respectively, described power-switching circuit is connected with the multicircuit relay circuit, and the output of multicircuit relay circuit is connected with liquid crystal display module to be measured.
Described single-chip computer control system is 51 series monolithic control system.
Compared with prior art, the beneficial effects of the utility model are: this system architecture is simple, and is easy to detect, only with a button, under 51 Single-chip Controlling, realizes the automatic control of liquid crystal display module multiple power supplies.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Embodiment
Below in conjunction with accompanying drawing technology contents of the present utility model is described in further detail.
One-touch automatic control multivoltage liquid crystal display module detecting system, by 51 single-chip computer control systems, power-switching circuit, multicircuit relay the electric circuit constitute, described 51 single-chip computer control systems are connected with power-switching circuit, multicircuit relay circuit respectively, described power-switching circuit is connected with the multicircuit relay circuit, and the output of multicircuit relay circuit is connected with liquid crystal display module to be measured.
During work, can be inner to 51 single-chip computer control systems with a key-press input, control again powering order and the power down sequence of the required power supply of liquid crystal display module to be measured by the mode of 51 single-chip computer control systems control multicircuit relay circuit.After powering up for module to be measured, single-chip microcomputer can directly write the detection picture that needs by the I/O mouth to module to be measured, realizes the various detections of product.
That the utility model main control MCU adopts is the 51 series monolithic STC89LE516RD+ that produced by STC Corporation, and external multicircuit relay circuit is used for controlling the logical and disconnected of each required road voltage of liquid crystal display module; Control simultaneously each I/O mouth of liquid crystal display module, write various detection data, realizing detecting need to.
The relay that the utility model adopts is a kind of electric control device, and it has control system and by the control system, is comprised of coil and contact sets two parts.Be exactly the characteristic of having used its this controllable switching in the middle of the native system, according to the needs of tested module, control the switch of each road voltage with it.
Described power-switching circuit, adopt a transformer input DC power, then in system, go out the multiple power supplies such as the required power supply of single-chip microcomputer, the required power supply of relay, module group backlight power supply, module power supply, module VLCD power supply with a plurality of mu balanced circuit conversion.
The course of work of native system is: after single-chip microcomputer powers up, postpone certain hour.The output of each road power supply reach stable after, under programmed control, press the sequence power on of module " backlight electric power-〉 module power supply-〉 module VLCD power supply ".In adding electric process, all certain time-delay to be arranged.Power up finish after, begin again the mouth by I/O, write the test data that needs in the module.Whether can observe the picture that shows at module this moment meets the requirements.After having carried out all tests, system can cut off the power supply to module automatically by the order of " module VLCD power supply-〉 module power supply-〉 module group backlight power supply ".After outage, module can be taken off, according to whether meeting the requirements, be included into different classes of in.And then put another module, and clicking and begin to detect key, beginning detects next time.In testing process each time, begin to detect button as long as click, system just can automatically perform complete testing process, so native system is called one-touch automatic control.
