摘要
在小区的每栋楼内设置楼宇集中控制器负责采集用户的耗能量,并将数据分类保存到数据存储单元。楼宇集中控制器和现场数据采集器之间的数据通信是利用CAN总线技术,和上位机之间的数据通信采用了GPRS技术。考虑到采集数据的容量和保存的可靠性采用FM1808铁电存储器。为提高系统的抗干扰能力,硬件方面采取了光电耦合、高频通路、放置去耦电容等措施,软件方面采取了利用DS12887时钟芯片每隔500ms将自动复位微控制器。
In a residential district, building centralized controllers are used to check the power consumed in each building, and store the data into the data storage unit. Building centralized controller could communicate with filed data collector by using CAN bus, and with upper computer by using GPRS. Considering the data capacity and reliability, FM 1808 ferroelectric memory is adopted. To enhance the anti-interference ability, some measurements in hardware, such as fiber-electronic coupling, high frequency channel, decoupling capacitors settlement are taken. Meanwhile, DS12887 is applied to reset microcontroller every 500ms.
