How People Counting System Communicate?

- Jan 25, 2018-

简要说明系统的组成以及各部分的功能如下。

 

前端安装的摄像机把信号通过同轴电缆传到服务端中,

每个服务端上装有多

块图像采集卡,

图像采集卡负责完成图像的模拟信号转换,

每个人数统计模块都

与某一路采集卡的输出连接,负责计算出对应图像的实时出入数据。

 

各文安人数统计模块每若干分钟产生一条出入人数的记录,

表示这期间进出

模块所辖区域的人员数量,

这些记录被称为原始记录,

系统保证它们在任何情况

下都不会被篡改。

每一条原始记录被复制成两份,

其中一份发送给服务器上的数

据服务器模块,

另一份则直接存入服务端本地备份。

这种设计使得数据服务器出

现问题时,

服务端上的人数统计模块仍然能够正常工作,

服务器恢复正常后,

留的数据将从服务端备份中提取重新发送给数据服务器。

 

数据服务器模块接收各人数统计模块发来的数据记录,将其存入中心数据

库。它定期对中心数据库进行自动维护,检查并修订异常数据,生成常规报表。

客户端软件是用户操纵数据服务器模块的主要方式,

通过它用户可以随时了解服

务端的运行情况,

监控各区域的实时数据,

查询或者修订中心数据库的历史数据。

特别地,

客户端还可以向用户提供指定区域的实时视频画面。

此外,

对系统各类

功能的配置也都可以通过监控客户端实现。

 

除了常规报表之外,用户可以随时使用浏览器访问数据服务器上的查询网

站,在这里用户可以对报表模板(包括常规报表模板)进行编辑、管理,完成各

种自定义的数据比较。

A brief description of the people counter ystem components and the functions of each part are as follows. The front-mounted cameras transmit the signals to the server through coaxial cables. Each IPAS server has multiple image acquisition cards. The image acquisition card is responsible for converting the analog signals of the images. Each video passenger counter is connected to a certain collection card of the output connection, is responsible for calculating the corresponding real-time access to the image data.


Every minute, the video passenger counter generates a record of number of people entering and leaving the area, indicating the number of people moving in and out of the module's area during the period. These records are called original records and the system guarantees that they will not be tampered with under any circumstances. Each original record is copied into two copies, one of which is sent to the data server module on the server and the other is directly stored in the local backup of the server.


This design makes the data server problems, the number of people on the server statistics module is still able to work properly, the server back to normal, stranded data will be extracted from the server backup to the data server. The data server module receives the data record sent by the statistics module of each number, and stores it into the central database. It regularly on the central database for automatic maintenance, inspection and revision of abnormal data, generate regular reports. Client software is the main way for users to manipulate the data server module. Users can keep abreast of the operation of the server, monitor the real-time data of each area, and query or revise the historical data of the central database. In particular, the client can also provide the user with a live video of the specified area. In addition, the system configuration of various functions can also be achieved by monitoring the client.


In addition to regular reports, users can always use the browser to access the data server query website, where users can report templates (including regular report templates) to edit, manage, and complete a variety of custom data comparison.
