Buildings Passageway Road Lighting Line Controller Based on Monolithic Computer

According to the characteristics of the buildings passageway road lighting line, to adopt monolithic computer controlling the building passageway road lighting line is researched. There, monolithic computer input signal use the switch signal which reflect the strength of the light (this switch signal is produced by photoelectric sensor). Hence, it can meet the requirements to use MSC-51 Monolithic Computer minimum system, plus the photoelectric sensor, output drive circuit and actuators. Thus, the system hardware and software structure can are simplified, and the costs can is reduced. A road lighting line controller making in this plan, can take light control and light-time double control for multiple road lighting lines simultaneously, can solve the problems that the control number of road lighting line and the allowable load of each channel are restricted, and can automatically adjust the time of power transmission and power outage according to the weather and the season. It can not only be used to control the indoor road lighting lines such as building passageway, its basic methods can also be used to control the outdoor road lighting lines of factories, offices, schools, residential districts and other places.
