报警系统

In this paper, we present a detection technology based on intrusion events in order to overcome the shortcomings of high false alert rate, serious redundant alerts and poor expression about the intrusion activities in today's intrusion detection systems. We describe the design ideas about the important methods used in this technology such as multi-sensor data fusion, raw alert distinguishment based on fuzzy rules and so on in detail.

在本文中，我们针对目前入侵检测系统普遍存在的误报率高、报警信息冗余现象严重和对入侵表述能力不强的缺陷，提出了一种基于入侵事件的检测分析技术，详细描述了该技术所采用主要方法的设计思想，如多传感器数据融合以及基于模糊规则的原始报警信息鉴别等。

At the same time, to make users maintain their system conveniently, we add a human-computer dialogue equipment in the system, users not only can observe all the state of the system but also can deal with the obstacle quickly and efficiently according to the alarm data , which applied by the equipment. It exhibit the humanization design in the new type electric control system of hoist much more.

同时为了用户的操作维护更加方便高效，系统使用了本公司开发的友好人机交互系统，使用户可以观察到系统的所有状态，并可根据该设备提示的报警信息来对系统进行快速有效的故障处理和日常系统维护，更加体现了起重机新型电控系统的人性化设计。

When use this system ,the users have to lay the sensors in the detecting area and lay MCU in indefectible area, then set the sensors address and data bits, after that, the users have to turn on the system by its pin number.

自动拨号报警是指系统借助已经普及的电话网自动拨打用户设定的电话号码并进行语音提示报警，故可实现低成本。

System should can be rise different grades of alarms, for example, high, high-high,low,low-low, and so on, the set of the alarm should can be finished by simply configuration.

系统应可产生不同级别，如高，高高，低，低低等报警。报警的设置应通过简单的组态即可完成。

The system should be able to produce different kinds of alarm levels, such as High Priority,High-High Priority,Low Priority,and Low-Low Priority.

系统应可产生不同级别，如高，高高，低，低低等报警。报警的设置应通过简单的组态即可完成。

Then the types of upper sensors are determined. The CMOS chip AT89C2051 is used in this system because there is only a small quantity of program to be stored. This system uses wireless transmission module D21DL to form the network of wireless transmission. In this way, such disadvantages as low removability and expansibility and longtime construction are avoided. Digital filtering method is applied to improve anti-jamming performance.

由于程序存储量较少，现场的CPU选用ATMEL公司的低档型芯片AT89C2051；为了避免采用有线数据传输导致的系统可移动性差、系统扩充性能差和系统布置线缆繁琐、施工周期长等缺点，本系统采用了无线数据传输模块D21DL构成系统无线网络传输；同时设计了包括电源电路、显示电路、存储电路和报警电路等构成系统的所有电路。

For practicality, this paper designs a new digital access system, which uses the Atmel Corporation's AT89S51 and AT24C02 as the chief chip and data cell store, combined with the function of keyboard input, digital display, intelligent alarm, recording the information of alarm, Video interphone and intelligence alarm.

本文从经济实用的角度出发，采用Atmel公司的AT89S51单片机与AT24C02作为主控芯片和数据存储器单元，结合外围电路设计了一款密码开锁、数字显示、密码储存、报警信息记录、可视对讲和智能报警的数字门禁系统。

The paper emphatically and deeply studied how to design and realize the functions sub-modules of the configurationally monitoring, the sub-modules include safety management sub-module, process flow sub-module, flow measurement sub-module, alarm sub-module, cure sub-module, parameter setting sub-module, report sub-module. The configurationally monitoring module possesses perfect functions of dynamically monitoring the production process of operating area, dynamically displaying parameter records of flow, pressure as well as temperature, inquiring and analyzing parameter records, drawing tendency charts, data alarming, automatic generating and printing all kinds of report forms and safely managing system.

本文继续深入的对构成组态检测模块的七个子模块；系统安全管理模块、工艺流程模块、流量计量模块、报警模块、曲线图模块、参数设置模块、报表模块的设计开发展开了研究，实现了对作业区生产过程的动态显示，流量、压力、温度等参数的动态显示与历史查询、曲线的绘制、数据报警、各种工作报表的自动生成和打印及安全管理等功能。

This system has the function of the thermometric , upper limit to report to the police, bottom the report to the police, temperature control and show on.

本系统具有测温、上限报警、下限报警、温度控制及显示功能。

This system has the function of the thermometric , upper limit to report to the police, bottom the report to the police, temperature control and show on.

数字温度控制系统具有测温、上限报警、下限报警、温度控制及显示功能。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
