本分布式小区智能网络模型采用符合现场总线(Fieldbus)要求
的CAN技术，以带CAN总线端口的主控机和单元控制器CAN端接口构成的
CAN网络层，下层为由带RS485端口的住户采集器和单元控制器RS485端
接口构成了RS485网络层，向上则利用PC机连接CAN网络层，作为智能
化小区管理中心，从而基本实现智能小区管理、控制、报警、信息采
集和自我检测的功能。
本文从智能小区、现场总线、CAN技术到“CAN+RS485”双底层网
络模型的软、硬件研究，较为详细的介绍了其设计、调试运行和期间
各种问题的解决。

在电子技术中，频率是最基本的参数之一，又与许多电参量的测量方案、测量结果都有十分密切的关系，因此频率的测量就显得更为重要。测量频率的方法有多种,其中电子计数器测量频率具有精度高、使用方便、测量迅速，以及便于实现测量过程自动化等优点，是频率测量的重要手段之一。在本次毕业设计中我们选择使用单片机来制作数字频率计，并在实际制作中采用了直接测频法。利用延时产生的时基门控信号来控制闸门，通过在单位时间内计数器记录下的脉冲个数计算出输入信号的频率，最终送入LCD中显示。这样制作出来的频率计不仅可以满足设计题目的参数要求，而且具有了单片机的稳定性和成熟性，且控制能力强，是一种低成本，高可靠的设计方案。-In electronic technology, the frequency is one of the most basic parameters, but also with a number of electrical parameters of the measurement program, the measurement results have a very close relationship between the frequency of measurement, therefore it is even more important. Measurement of the frequency of a number of means, electronic measurement of the frequency counter with high precision, easy to use, rapid measurement, and measurement is easy to realize the advantages of process automation is an important means of measuring the frequency of one. Graduates in this design we have chosen to make use of single-chip digital frequency meter, and used in the actual production of a direct
