Abstract

The utility model provides a precise lock synchronous bell ringer which comprises a synch signal receiving module, a main control module, a bell ringing control module and a time display module; the main control module is respectively connected with the synch signal receiving module, the bell ringing control module and the time display module; the synch signal receiving module is used for receiving unified precise time information, the main control module displays the precise clock information through the time display module and drives the bell ringing module to ring the bell according to the preset time.

Description

The synchronous Belling apparatus of precision clock

Technical field

The utility model relates to a kind of electronic equipment, the synchronous Belling apparatus of especially a kind of precision clock.

Background technology

Traditional school, the Belling apparatus of factory all adopt the local microcontroller timing mode, the time error of every day can reach 1 second, cumulative errors can reach ten minutes more than, and the time of ringing a bell of different Belling apparatus also has difference, cause the same daily schedule that different ringing a bell constantly arranged, for going to school and leaving school and the daily schedule on and off duty is caused very adverse influence.

Summary of the invention

The shortcoming of above-mentioned traditional Belling apparatus for a change, the utility model provides a kind of precision clock synchronous Belling apparatus.

The utility model comprises synchronizing signal receiver module, main control module, jingle bell control module, the time showing module, it is characterized in that, main control module respectively with synchronizing signal receiver module, jingle bell control module, the time showing module connects, the synchronizing signal receiver module is used for receiving unified precise time information, main control module shows precision clock information on the time showing module, and driving jingle bell control module is carried out jingle bell control on the time point that is provided with, all Belling apparatus all have same precise time, ring a bell at synchronization.

The beneficial effects of the utility model are, the time is accurate, and the time unification of ringing a bell has higher utility, economic worth.

Description of drawings:

Fig. 1 is a schematic diagram of the present utility model, and Fig. 2 is the utility model electricity structural drawing.

Embodiment:

As shown in Figure 1, the utility model comprises synchronizing signal receiver module 1, main control module 2, jingle bell control module 3, time showing module 4, it is characterized in that, main control module 2 respectively with synchronizing signal receiver module 1, jingle bell control module 3, time showing module 4 connects, synchronizing signal receiver module 1 is used for receiving unified precise time information, main control module 2 shows precision clock information on time showing module 4, and driving jingle bell control module 3 is carried out jingle bell control on the time point that is provided with, all Belling apparatus all have same precise time, ring a bell at synchronization.

As shown in Figure 2, the synchronizing signal receiver module adopts GPS receiving circuit receiving demodulation gps signal, therefrom signal is as the time reference of Belling apparatus extraction time, because gps clock is produced by cesium-beam atomic clock, time precision is high thereby can make the very high microprocessor of accuracy of timekeeping of Belling apparatus adopt the PIC16F873 of Microchip company.This chip adopts 14 class RISC order set, and aboundresources in the sheet includes A/D converter, EEPROM etc., makes Belling apparatus save external A/D change-over circuit and eeprom chip, has simplified circuit system.Single-chip microcomputer can be judged whether power down of primary power by the branch pressure voltage of R1 and R2.When primary power had electricity, the 5V DC voltage was GPS receiver module and single-chip microcomputer power supply behind D1, provides trickle charge for battery BAT1 after the R3 current limliting; When the primary power power down, battery BAT1 is single-chip microcomputer and the power supply of GPS receiver module behind D2, and when system still can normally walk during with the primary power power down of assurance system, but system stops other functions.The branch pressure voltage of R4 and thermistor Rt1 changes with the variation of environment temperature, and single-chip microcomputer carries out the A/D conversion to this branch pressure voltage, tables look-up and can measure environment temperature.Hummer BAK1 and LED 1 are pressed the acousto-optic hint that effectively reaches jingle bell output for button.Whether the external electric bell of Single-chip Controlling relay J 1 decision jingle bell.The internal pull-up resistor that connects 5 I/O pins of button is opened.LCD MODULE YDS12864 and single-chip microcomputer adopt serial port to link to each other, and show the information when information such as current year, month, day, hour, min, second, week, temperature and system are provided with in Chinese mode.

Claims

1. synchronous Belling apparatus of precision clock, comprise synchronizing signal receiver module (1), main control module (2), jingle bell control module (3), time showing module (4), it is characterized in that, main control module (2) respectively with synchronizing signal receiver module (1), jingle bell control module (3), time showing module (4) connects.
