With the above structure adopted, a general input and output port of the microcontroller unit is adopted to control the hard reset of the electronic paper screen. The method is simple in design. With the method adopted, hardware cost increase is not needed, and screen errors in the use process of the electronic shelf label can be effectively eliminated.
Description
Technical field
What the present invention relates to is the field, particularly a kind of electronic shelf label of wireless communication technology and the method for correction screen display mistake.
Technical background
Electronic Paper due to power consumption extremely low, contrast is high, can be by force readability, is widely used in electric paper book, Sign Board, the various fields such as electronic shelf label, and electronic bin is exactly a wherein very important utilization.But due to the Particular craft of Electronic Paper, make the display screen to its control overflow is more common high.The data flat cable of electronic paper screen also more crypto set.In the application process of electronic bin, often there will be due to environment temperature, the factors such as vibration, cause display screen to occur the situation of screen mistake, as skew, flower screen etc.Meanwhile, because the refreshing frequency of electronic bin is very low, once there is these situations, mistake will remain on screen for a long time.Even if even there is screen-refresh also cannot eliminate the mistake of screen.Common solution is manually extracted by the battery of electronic shelf label, ressembles back more a moment later, electronic shelf label is resetted.It is loaded down with trivial details that such error correction method uses program in the operating process of reality, will bring operational trouble in time there is large-scale electronic curtain.
Summary of the invention
The technical issues that need to address of the present invention are the one conveniently correcting methods after electronic bin screen display mistake.
For solving the problems of the technologies described above, the present invention is to provide a kind of electronic shelf label, mainly be made up of electronic-paper display screen, storer, microprocessing unit, battery, crystal oscillating circuit and wireless module, the input/output port of described electronic-paper display screen, storer and wireless module is connected to microprocessing unit by data line, described battery is also connected microprocessor unit with the output terminal of crystal oscillating circuit by data line, between microprocessor unit and electronic-paper display screen, be also provided with hard reset device; Described hard reset device is made up of signal deteching circuit, signal generating circuit, signal circuit, normally closed switch, main frame and controller; Described signal deteching circuit, for detecting the signal that microprocessor unit sends timely; Described signal generating circuit, for detecting that N number of reseting pulse signal that microprocessing unit sends changes into hard reset signal; Described signal circuit, for by the Signal transmissions of hard reset to main frame, described main frame is connected to controller, after main frame receives hard reset signal, transfers controller and controls electronic-paper display screen internal register and return to original state by force; Described normally closed switch, is used for controlling the connection of hard reset device.
Mistake is shown in order to what can know electronic shelf label screen timely, so also include the voltage detection module and current detection module that are arranged in parallel in microprocessor unit, in time detecting electric current or voltage has one to occur abnormal, just can start hard reset device;
Further, scan module, conversion module, update module and format library module is also comprised in the microprocessor unit described in technique scheme.Scan module, is used for scanning the data utilizing wireless module to receive, information is effectively classified, dispose some junk information; Conversion module, is used to useful information to change into the formatted output that electronic shelf label can show; Update module, is used for carrying out orderly renewal to the information of in the past long-term storage, ensures that microprocessing unit has enough running spaces; Format library module is the format library in microprocessing unit module, is used for facilitating the format conversion of information.
Correct a method for electronic shelf label screen display mistake, comprise the following steps:
S1: the electronic bin with hard reset device is switched on power;
S2: the current detection module in microprocessor unit and voltage detection module detect electronic bin;
S3: after discovery voltage and current meets ratings, normally closed switch not conduct, system is normally run; In time finding that electric current or voltage have an exception, hard reset device will be started;
S4: normally closed switch is opened, microprocessor can send signal, is delivered to hard reset device;
S5: the signal deteching circuit meeting start detection signal in hard reset device;
S6: the signal that signal is changed into hard reset by signal generating circuit exports;
S7: pass the signal along to electronic-paper display screen, controls its internal register by force and returns to original state.
Wherein hard reset device can be hand.In time running into some small-sized electronic shelf labels, also the mode of manually button can carry out hard reset device to link up.
After adopting said structure, the universal input and output port of micro controller unit is adopted to control the hard reset of electronic paper screen; When screen display is made mistakes, micro controller unit sends hard reset signal, makes the register cell of electronic-paper display screen return to original state, thus eliminates the problem of display mistake.The method simplicity of design, without the need to increasing new hardware cost, effectively can solve the screen mistake in electronic shelf label use procedure.
