The intelligent clock control system of this thesis mainly refers to the household appliances of the clock display, timing setting and timer switch. This system is based on PIC16F72 microcontroller core, 4 LED digital display time, and used the DS1302 clock chip to complete the basic functions of the real-time clock. Also used the 24C02 to store timing data,to achieve the timing control of vertical freezers. This paper does in-depth analysis and research on time control for vertical freezers, discusses structure and design project of the control system, introduces system design and working principle of the device, and gives detailed analysis of the hardware circuit and physical design based on PIC16F72 MCU used as control unit. The software design is used to experiment with the clock display and timer control, and the result proves feasibility of the schemes. Experimental results show that design of time control for vertical freezers is reliable. Novelty of the show is easier to attrac
