Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail。

As shown in Figure 1-2; this utility model one Intelligent eyesight protection desk lamp; it includes the lamp holder 1 connected on lamp socket 5, lamp stand 6 and lamp stand 6; and it is connected to supply unit with lamp socket; the surface of described lamp socket 5 is provided with sensor group 3; and sensor group 3 is connected with the ultrasonic ranging within lamp socket 5/light-metering module and humidity detecting module; lamp socket 5 is internally provided with control module; it is attached thereto and is provided with alarm module, and ultrasonic ranging/light-metering module and humidity detecting module are also coupled to control in module；The front of described lamp stand 6 is provided with display module 2 and is linked in control module。

Preferably, described control module is also associated with light correction module, and light correction module is arranged in the supply line of lamp holder 1。

Preferably, described lamp stand 6 is rods, and elevation angle is adjustable。

Preferably, it is provided with voice broadcast module in described lamp socket 5, and is linked in control module。

Preferably, described display module 2 includes display screen and the control circuit being attached thereto, and is linked in control module；Display screen has clock and text importing module。

What ultrasonic ranging/light-metering module adopted be one has temperature-compensating range finding, thermometric, the strong Trinitarian ultrasonic sensor modules of light-metering。Module comprises the high accuracy range measurement of real-time temperature compensation, and scope of measuring, up to 1CM ~ 600CM, uses the interface of I2C to communicate with controlling module (main frame), it is possible to automated to respond to control the I2C control instruction of module (main frame)。

In this utility model, alarm module adopts buzzer alarm circuit, and it includes the audion of a buzzer, a resistance, a positive-negative-positive。Wherein resistance plays the effect of dividing potential drop current limliting, and audion plays the effect of a switch。The base stage of one termination audion of resistance, an end receives the P1.0 port controlling module (main frame), realizes the alert operation of buzzer by controlling the height of P1.0 port level, when P1.0 port exports high level, buzzer works, and during output low level, buzzer does not work。

This utility model except from conventional sitting posture, light intensity, protect vision by these three aspect between at the moment except, also add Humidity Detection, such as Fig. 2。When people's reading with single-hearted devotion or operating computer too plenty for the eye to take it all in, frequency of wink can significantly reduce, eyes are stared at for a long time on screen, not only result in eyestrain, cause visual deterioration, due also to xerophthalmia, " turn a blind eye to " between cornea and eyelid and easily cause scratch, thus cause that eyes are dry and astringent, inflammation and pain, form xerophthalmia。So, protection vision also to pay special attention to the moisturizing of eyes。And when surrounding is excessively dry; easily lead to our visual impairment; therefore ambient humidity be also us it should be noted that index; when ambient humidity is not up to standard; report to the police; remind people's current environment less by eyes work, it is possible to select to increase ambient air humidity, protect our vision with this。Humidity sensor adopts modular organization, belongs to rate-adaptive pacemaker formula Integrated Humidity Sensor, and the output frequency when 55%RH is 8750Hz(offset), when relative humidity changes to 95% from 10%, output frequency is just reduced to 8030Hz from 9560Hz。This sensor has that the linearity is good, capacity of resisting disturbance strong, is easy to join digital circuit or control module (main frame), and it is generally single-chip microcomputer。

The work process of light correction module is that the LED luminance in light correction module reaches the highest when outside light intensity is less than 400 lux, along with the increase of outside light intensity, LED descending luminance, when exterior light powerful in 600 lux time, extinguish LED。What the light correction module in this device adopted is PWM dimming mode。Control to flow through LED electric current by the PWM cycle and dutycycle adjusting single-chip microcomputer output, change the brightness of LED with this。Light correction and LED illuminating circuit include one and play the audion of on-off action, the resistance of two blood pressure lowering metering functions, an electrochemical capacitor, a Qiao Dui and one group of LED for illuminating, as shown in Figure 2。When one-chip machine port exports high level, triode ON, LED is lighted, and audion cut-off during output low level, LED is extinguished。When changing the dutycycle of one-chip machine port output pulse, the electric current flowing through LED just changes, the visual persistence effect of recycling people, reaches to regulate the effect of LED luminance。

What display module adopted is the Chinese display screen of one piece of 128*64。128X64 with Chinese word library is that one has 4/8 parallel-by-bits, 2 lines or 3 line serial multiple interfaces modes, the internal dot-matrix lcd module containing GB one-level, two grades of simplified form of Chinese Character character libraries；Its display resolution is 128 × 64, built-in 8192 Chinese characters, and 128 ascii character-sets. utilize this module interface mode flexibly and operational order simply and easily, may make up full Chinese man-machine interaction graphical interfaces。The Chinese character of 8 × 4 row 16 × 16 dot matrix can be shown. also can complete figure and show. Low-voltage Low-power is its another distinguishing feature。By the liquid crystal display scheme of this module composition compared with the dot matrix LCD module of same type, and though hardware circuit or display program will be succinct many, and the price of this module is also slightly below the graphic LCD module of identical dot matrix。

Adding voice module in this utility model, this voice module can work with alarm module simultaneously, while warning can voice broadcast, remind people to note the protection of vision。When single-chip microcomputer internal clocking 45 minutes, it is possible to play eye exercises by this module, so can better more fully protect prevention our vision good。Voice broadcast module adopts the product I SD4004 that American I SD company releases。ISD4004 speech chip adopts CMOS technology, include the many electrical level flash storage displays of crystal oscillator, antialiasing filter, smoothing filter, automatic silencing, audio-frequency power amplifier and high density etc., therefore, little peripheral components is only needed just to may make up a complete Sound Record & Playback System。Single-chip microcomputer exchanges data with ISD4004 by serial line interface SPI。All serial data transmissions start from SS trailing edge. and rising edge clock moves into data, and trailing edge removes。Data command form is that 8 control codes add 16 bit address codes。
