Electronic calendar is a kind of daily timing tool of widespread use, can to year, the moon, day, the time, branch, second carry out timing, also have the leap year compensation, functions such as quarter-bell.But basically because this electronic calendar does not have other practical functions, people generally also only are provided with it on the wall as common timing tool, and daily life is not had the too big help of performance.
Summary of the invention
The purpose of the utility model is: propose a kind of integrated perpetual calendar inquiry, lunar calendar inquiry, notice of meeting; Prompting every day (historical today and diet are reminded), temperature detection, unit conversion; The multi-functional perpetual calendar of utility functions such as counter is to overcome the deficiency that prior art exists.
For realizing the purpose of the utility model; Adopt following technical scheme to be achieved: a kind of multi-functional perpetual calendar comprises microcontroller, the power supply that is electrically connected with microcontroller at least; The real-time clock unit; And the short in size LCDs that is connected with microcontroller through short in size screen chip for driving, it is characterized in that: described microcontroller also is connected with the keyboard of being handled and being controlled by it, storage unit; Temperature detecting module, alarm clock module and a matrix liquid-crystal display screen that is used for display text information.
As preferred version: described real-time clock unit is provided with independent current source, and the real-time clock unit is connected through iic bus with microcontroller.
As preferred version: described storage unit is the serial FLASH chip that stores historical events information, unit conversion formula and Hanzi font library file, and it is connected with microcontroller through the SPI serial line interface.
Compared with prior art; The beneficial effect of the utility model is: the utility model is on the basis of realizing electronic calendar, time clock feature; Integrated is prompting every day on basis with the clocking capability; Notice of meeting and healthalert function (alarm clock function adds that information shows) help people to realize more regular more healthy life.The utility model is also subsidiary to have the utility function that will use often in the daily lifes such as counter, unit conversion and temperature detection, for the user provides more convenience.
