CN202127525U - Road lamp centralized controller based on advanced reduced instruction set computer machine (ARM) processor - Google Patents

Abstract

The utility model relates to a road lamp centralized controller based on an advanced reduced instruction set computer machine (ARM) processor, which comprises a power supply part, a human-machine interaction control part, a clock control part, an ARM 9 central control part, a storage part, a liquid crystal display (LCD) display part, external device interfaces (such as a general packet radio service (GPRS) interface, an Internet interface, a universal serial bus (USB) port and a recommended standard (RS) 232 serial interface) and a relay control part. The ARM 9 central control part is in charge of controlling and coordinating each module to obtain preset functions. The storage part is used for storing preset information of a road lamp controller (information of areas within the administration, control decisions and the like) and working parameters and important history operation data of each road lamp (such as failure occurrence condition, alarming records and the like). The centralized controller can preset a time table for turning on and turning off the road lamp, collecting time of road lamp working parameters, higher and lower limits of current and the like to conduct automatic alarming. An RX0 and a TX0 are connected with S3C2440A and an electric carrier wave module, and an RX1 and a TX1 are connected with the S3C2440A and a GPRS module to transmit control orders and data. An electricity module is used for starting/cutting off power supply of an area which the road lamp is in charge of. When the daytime comes, the road lamp stops working, and the electricity module breaks a relay, thereby avoiding safety problems caused by long term electrification of communication lines. The human-machine interaction interface provides a function of operating on site, system maintaining workers can input orders through a touch screen on site to control the centralized controller and change or acquire control set information in a lighting area.
