Abstract

This paper studies the calendar system controlled by STC89C52, with DS1302 clock chip timing, DS18B20 temperature sensor collecting the environmental

temperature, the 15 bit of nixie tube displaying. The hardware circuit is composed of single-chip microcomputer controlling circuit, temperature sensor module, clock module, nixie tube displaying module and time synchronization circuit. Schematic is simulated by Proteus ISIS 7 Professional. Program is written in C language by Keil uvison4.Proteus ARES 7 Professional is used to layout PCB production. The production of the hardware circuits uses the method of heat transfer. This paper mainly introduces design ideas, demonstration program and working principle of hardware circuit. By hardware circuit debugging, the hardware production achieves the design requirements at the beginning, and proves the feasibility of the design scheme. The calendar hardware circuit has the advantages of visual display, excellent night vision effect, data conveniently reading, reasonable element layout and rich extension function under test in the actual environment.

Keywords: Nixie tube, STC89C52, DS1302, DS18B20, Digital calendar
