【摘要】： 校園作息時間控制系統(tǒng)主要用于學(xué)校，對一些以24小時為周期的開關(guān)量進(jìn)行自動控制。如上下課打鈴、教學(xué)樓照明的定時開與關(guān)、學(xué)生宿舍燈及校園路燈的定時開關(guān)、水泵的定時啟動以及自來水供水時間控制等等。
該控制系統(tǒng)是采用AT89S52單片機(jī)來實(shí)現(xiàn)對上述開關(guān)量的控制，利用DS12887時鐘芯片來提供時鐘信息，設(shè)有六位數(shù)碼管、可以實(shí)時顯示時間、系統(tǒng)還設(shè)有輸入鍵盤，用以修改實(shí)時時鐘，體現(xiàn)了系統(tǒng)簡單、工作穩(wěn)定可靠、價廉、控制時間精確及系統(tǒng)體積小等優(yōu)點(diǎn)。
【Abstract】: The campus the daily timetable control system which is mainly used in the campus, it auto-control some switches which have periods of 24 hours. Such as the bells ringing when classes begin or finish, the time switches of lamps in teaching buildings and student dormitories, the time start-up of water pump, and the tap water supply control system, etc.
This control system carries out the switch parameter controls all above by SCM AT89S52. It uses the clock chip called DS12887 to provide the clock information. It could show the real time with 6 bit digital tube. And it could modify the real time clock with the input keyboard. The system is simple, the running is steady and dependable, the controlled time is exact, and the physical volume of the system is small, all the advantages above can be incarnated in this system.
