Description
Technical field
The utility model relates to a kind of electric energy meter display system, particularly relates to a kind of gesture and controls intelligent meter liquid crystal display systems.
Background technology
At present, intelligent electric energy meter is popularized in China, but in the process that reality uses, find some problems, wherein have a class problem values to obtain everybody to pay attention to, be exactly usually be arranged on the electric energy meter in corridor or outdoor table case, only stay the window of a LCDs size, user can not touch the display button of table, also just inquires about the more relevant informations except following and showing less than oneself ammeter of user.
Present state net intelligent electric energy meter all by following the aobvious and aobvious two kinds of display modes of key, follows aobvious content fewer, when table meter normally works, follows the display time intervals automatic cycle display of aobvious screen content basis setting.Total be exactly follow aobvious screen content mainly show the information on a small quantity such as the current electricity of meter and time.It is then more that key shows content, comprises table number, mailing address, each rate electricity, bimestrially recently freezes electricity and current real-time Monitoring Data (comprising the information such as voltage, electric current, power).Now intelligent electric energy meter in the market, mainly installs concentratedly in table case, if user wants the more electricity consumption situation understanding own home, the mode being difficult to be inquired about by button sees corresponding data, must have been come by the staff of power administration.This understands detailed power information to user and brings great inconvenience.
More domestic intelligent electric meter manufacturers, for meeting customer need, add and to utilize in family conventional telepilot to carry out key to show page-turning function.Although achieve contactless page-turning function when there being telepilot like this, but also there are some problems: the communication protocol of (1) various telepilot and traffic rate disunity, realize infrared key show page-turning function so want telepilot, the instruction sent telepilot is needed not do the judgement of concrete data frame format, this just causes electric energy meter can wake up under the interference of the strong a little light such as daylight, backlight Chang Liang, enter key display mode, the table meter overall power of increase; (2) susceptibility due to table meter infrared receiving tube is variant, the table meter backlight had under causing similarity condition is bright, liquid crystal shows according to key display mode, some table backlights do not work, normal cyclic pattern shows, this just causes very large puzzlement to user, and user can think that the table meter of own home is out of joint, causes the suspection of his-and-hers watches meter metering accuracy; (3) user is when checking that key shows content, can only to scroll down, can not to scroll up, if key aobvious screen number is a lot, user wants the content of checking just to twist over, and will all look into that screen reading through and just can return to and will see by all screens; (4) if subscriber's meter meter out of doors, it is very inconvenient that user will be with telepilot out to check from family.
Summary of the invention
The purpose of this utility model is to provide a kind of gesture to control intelligent meter liquid crystal display systems, and this system IR gesture sensor substitutes button operation, easy to use, few by external environment restriction, ammeter entirety is improved, reduces production cost, improve the class of safety protection that table meter is overall; User is facilitated to check table meter displaying contents.

Embodiment
Below in conjunction with embodiment, the utility model is described in detail.
Structured flowchart of the present utility model as shown in Figure 1.In figure, MCU is core control circuit of the present utility model, the functions such as the calculating of responsible intelligent electric energy meter and control; MCU passes through I
2c bus marco display circuit, the display human-computer interaction interface showing electric energy meter is responsible for by display circuit; Metering circuit is connected by spi bus with MCU, is responsible for electric energy metrical correlation function; Power circuit provides+12V and+5V direct supply for electric energy meter; The I of infrared gestures detection circuit and MCU
2c bus connects, and is responsible for detecting infrared hand signal, and operating key shows content, from left to right still realizes downward page turning and the upwards page turning of screen according to the direction of gesture from right to left; The I of memory circuit and MCU
2c bus connects, and is responsible for correlation parameter and the service data of storage of electrical energy table; Key circuit is connected by IO port with MCU, is responsible for the information input of electric energy meter; Safety certification circuit is connected by ISO7816 interface with MCU, is responsible for the security authentication operation of electric energy meter.
The utility model uses infrared gesture sensor, and the key as intelligent electric energy meter shows input control signal, and infrared gesture sensor detection circuit as shown in Figure 2.In Fig. 2, VCC is+5V power supply; Infrared gesture sensor chip passes through I
2c bus is connected with MCU, and INTB pin is look-at-me, notifies that MCU is to read data when becoming low level; SDB pin is the enable pin of chip, Low level effective; Wherein SDA, SCL, INTB pin needs 4.7K resistance pull-up, and SDB pin needs 100K resistive pull-downs; RX2 is the infrared LED receiver signal input of passage 2, and RX1 is the infrared LED receiver signal input of passage 1, and IRLED is infrared emission pin, connects infraluminescence pipe; First arranging configuration register before using infrared gesture function is infrared gesture mode, can arrange the intensity of infrared emission simultaneously, and this intensity determines to control the gesture of ammeter operation and the distance of table, can reach 15cm farthest.When electric energy meter normally works, if there is hand to pass through in infrared remote receiver effective range before table, MCU will receive the interrupt notification of gesture sensor, when hand is that this direction slips over from PD2 to PD1, the MD position reading the status register of infrared gesture sensor is 01, contrary then what read out is 10, thus by can realize the judgement of these data to liquid crystal display turns over and under the control of turning over.
The software flow that in the utility model, the infrared gesture of intelligent electric energy meter controls as shown in Figure 4, below accompanying drawing explain that the infrared gesture of intelligent electric energy meter controls flow for displaying:
Step 601, MCU passes through I
2c bus is configured infrared gesture sensors register, by model selection, is configured to gesture control model, is selected by infrared emission size of current, the detecting distance of configuration gesture.
Step 602, when there being gesture to pass through in coverage, the INTB pin of infrared gesture sensor sends a look-at-me to MCU.
Step 603, MCU passes through I
2c bus reads the status register of infrared gesture sensor.Judge that gesture is from left to right or from right to left by register value.
Step 604, MCU turns over by determining liquid crystal to turn over still to the judgement in gesture direction.
