基于电力线载波通信的智能小区的研究与实现
|
摘要
智能小区的普及化发展要求智能小区面向低成本、高性能的目标设计。无论从技术方面或者经济方面考虑,采用电力线载波通信是实现小区智能化的最佳方式。论文建立了低压电力线的传输模型,在此基础上提出采用直接序列扩频载波通信来克服电力线作为传输介质具有的高削减、高噪声、高变形等缺点,使电力线成为一种可靠的通信媒介。在智能小区的设计方案中,小区内采用电力线作为通信介质,采用适合我国电网实际情况的电力线Modem SC1128作为通信接口芯片组成小区网络;家庭网络通过家庭网关与小区管理中心进行通信;小区管理中心一方面对整个小区各个家庭信息进行收集、整理和存储,另一方面和Internet连接,供家人远程查询家庭信息和控制家庭设备。本文设计了小区中家庭内部电力线载波扩频通信模块;并且对主从模块的通信进行了调试,验证系统的可行性。最后,根据小区实际情况进行了上位机软件的探讨,并基于Visual Basic 6.0设计了上位机管理系统,以实现数据记录的保存、维护、分析、查询统计、打印等。
The universalization of intelligent district request it is designed with low cost and high performance. Power line communication (PLC) is the best way to correspond with the respect of technical or economical reasons. The power line transmission model has been established to explain the direct sequence spread spectrum(DSSS) is the the best method to modulate the signal to overcome the power line’s shortcomings of high reduction, high noise, high distortion, and so on and make it possible to be a workable correspondence medium. In the intelligent district design proposal, the power line and the modem chip SC1128 which is adequate for our country’s power line net situation are used to compose the the district–net; The family network can communicate with district administrative center through family gateway. The district administrative center has follow functions: first ,it can collect, reorganize and memory the dates of families,second,it can connect with internet and the family members can make long-distant inquiry and control family equipments. The article designs the PLC net of family based on expanding frequency,and debugs the ability of correspondence between host and guest modules. The facts demonstrate the system is workable. Finally, this paper discusses the software of above machine of the district administrative center, and present above machine management system according to Visual Basic 6.0 to fulfill such operation with data like saving, analysis, maintenance, inquiry and statistic and report forms printing.
