The products of the work go as followed : develope the uniform asi slave module , which could be linked with many kinds of sensors . the condition of slaves can be configured by the master . develope special transmitter for asi master , which needs only two control wires 课题的研究成果有： （ 1 ）开发了统一的asi从站模块，可以接各种传感器，从站的信息可以由主站来配置； （ 2 ）开发了专用的asi主站传输控制器，只需要两根控制线。
The integral calculus formula is deduced , in which the first derivative of physical measures of system with respect to time equals the partial derivative of physical measures of control field to time plus clear flux of physical measures passing the control line within unit time 推导出交通流系统所具有的物理量对时间的全导数的积分公式，即系统内物理量对时间的全导数等于控制域内该物理量对时间的偏导数与单位时间经过控制线的该物理量的通量之和。
System control module accomplishes many functions , such as systemic initialization , controling work of the system , man - machine interface and selecting channel . it communicates with other modules by i2c bus . timing signals are inputed into microprocessor through p1 port and control signals are provided through p2 port 系统控制模块和其他模块间的通讯基于i ~ 2c总线，并利用了p1口进行各时钟信号的检测和利用p2口的各线作为控制线宋控制相应模块的工作。
The last chapter gives in details the implementation of the system , including a full account of custom files , some import modules and the realization of key use cases , and the methods of how to control the number of threads and to make local resource be consistent with the server ' s 第四章讲述了系统的重要实现细节，包括系统自定义文件格式的说明、重要功能模块和关键用例的具体实现，并说明了控制线程泛滥、同步本地和服务器文件资源等关键技术的实现方法。
Application program mainly contains a multi - thread program , including main control thread , preview thread and encoding thread . main control thread initializes encoder end system and deals with control message delivered from user interface ; preview thread reads preview data and displays it on the screen by the way of user ’ s request ; encoding thread reads encoded data and transfers it to server process . according to user ’ s requirement , server saves the encoded data or transfers it to client by network 主控制线程实现整个编码端系统的初始化和处理用户界面传下来的控制信息;预览线程从编码系统读取预览数据并按照用户界面传下来的要求在屏幕上显示预览视频;编码线程从编码系统读取编码数据并把数据转发给服务器进程,由服务器进程实现数据的录象存盘或通过网络向远程客户端传输。
According to the rule of mine safety regulations , an intrinsically safe pilot circuit with perfect performance for underground motor intelligent protective systems is put forward , which can effectively avoid the phenomenon of self - starting that is caused by the earthing of control lines before starting motors , at the same time , can reliably cut off the switches to ensure the safety of underground production under operation condition no matter what the faults of short circuit , open circuit and earthing in the control circuits happened 根据煤矿安全规程规定设计了性能完善的本质安全型先导电路，起动前它能有效地防止因控制线接地造成自起动现象的发生，而且在运行中无论控制线发生短路、断线还是接地故障，它均能可靠跳闸，确保生产的安全，该先导电路的性能指标达到了国内领先水平。
