Fig. 2, in a kind of Fig. 1 of realization, music is rung a bell the composition frame chart of playing circuit.

Embodiment

Below in conjunction with accompanying drawing and preferred scheme, principle of work of the present utility model is described further.

As shown in Figure 1, it is composition frame chart of the present utility model, a composition frame chart for system of specifically ringing a bell based on GPS time service Intelligent Single-Chip Based music, this system comprise power module, GPS, ring a bell playing circuit and button of AVR single chip, human body infrared induction module, LCD MODULE, temperature detecting module, music arrange module; Described power module playing circuit of ringing a bell with GPS time service module, AVR single chip, human body infrared induction module, LCD MODULE, temperature detecting module and music is respectively electrically connected, and power supply module provides working power for the module be attached thereto; Described AVR single chip is control core, and what be attached thereto is GPS time service module, LCD MODULE, music ring a bell playing circuit, button arranges module and temperature detecting module; The output terminal of described human body infrared induction module connects the input end of LCD MODULE.

As shown in Figure 2, be that in a kind of Fig. 1 of realization, music is rung a bell the composition frame chart of playing circuit, this circuit take MCU as control core, and it is connected with MCU, decoding chip, SD card module and storer.

Following principle of work composition graphs 1 and Fig. 2 and preferred version illustrate, and described AVR single chip adopts is ATmega16 single-chip microcomputer, and the EEROM data storage area that its inside carries stores separately the time data of ringing a bell arranged by button.After each single-chip microcomputer power-off restarts, the time data of ringing a bell arranged before automatically reading, uses more convenient.

What described GPS time service module adopted is U-BLOX NEO-6M GPS module receiving demodulation gps signal, time in gps signal is produced by cesium-beam atomic clock, time precision is high, therefore therefrom extraction time signal as the time reference of the system of ringing a bell, the accuracy of timekeeping of the system of ringing a bell can be made greatly to improve.

Adopting in described LCD MODULE is LCD12864 display screen, and it is mainly provided with 3 groups of display interfaces: (1) opening initialization interface; (2) perpetual calendar display interface, has the information such as Gregorian calendar year, month, day, week, the lunar calendar and Temperature displaying; (3) ring time arranges interface, for arranging ring time, often organizing 3 setting options, can arrange 50 groups of ring time altogether.

Employing in described temperature detecting module be DS18B20 temperature sensor, its precision is high.The temperature detection of DS18B20 and numerical data export and are integrated on a chip, thus interference resistance is stronger, and an one work period can be divided into two parts, i.e. temperature detection and data processing.

Described button arranges module for the setting to ring time, be respectively equipped with setting, move to left, move to right, addend, subtrahend and confirmation totally 6 buttons, press " setting " key system entry time and interface is set, regulation time utilizes " move to left, move to right, addend, subtrahend " key, setting completed presses " confirmation " key, system will keep the time of setting.

Principle of work: after system electrification, by the backlight of human body infrared induction module control LCD12864 display screen, the backlight that its induction range then opens LCD12864 is entered when there being people, people leave induction range then automatic time delay close the backlight of LCD12864, to reach the object of energy saving of system, U-BLOX NEO-6M GPS module enters initialization procedure, and LCD12864 shows initialization interface; ATmega16 single-chip microcomputer serial ports receives the data message of GPS module, and is parsed the time signal of needs by program, as the time reference of the system of ringing a bell; After U-BLOX NEO-6M GPS module receives and solution is transferred to reliable and stable gps data information, system enters perpetual calendar display interface, ATmega16 single-chip microcomputer gathers the temperature information of DS18B20 temperature sensor simultaneously, is presented on LCD12864 screen by gps time and DS18B20 temperature information; According to daily schedule, LCD12864 can arrange 50 groups altogether ring a bell the time, when the time of ringing a bell arranged is identical with the reference time of GPS time service module, ATmega16 Single-chip Controlling music is utilized to ring a bell playing circuit using voice broadcast and the of short duration music the tinkle of bells as upper and lower class that sounds.

The utility model adopts gps time to be the system of ringing a bell of benchmark, accurate when it is walked, easy to use, man-machine interface is friendly alternately, and this system of ringing a bell successfully achieves trial run in Wuxi Engineer College of Jiangsu Province at present.If the data transmission of native system adopts wireless transparent module to transmit, be separated with single chip control module by gps signal module, then can realize the control overflow only using a GPS module to ring a bell to Multi-Machine Synchronous easily.Visible, native system has certain promotional value.
