[Program doc] USB_RS-485_collection

Description: 在工业生产和科学技术研究的各行业中，常常利用PC或工控机对各种数据进行采集。这其中有很多地方需要对各种数据进行采集，如液位、温度、压力、频率等。现在常用的采集方式是通过数据采集板卡，常用的有A/D卡以及422、485等总线板卡。采用板卡不仅安装麻烦、易受机箱内环境的干扰，而且由于受计算机插槽数量和地址、中断资源的限制，不可能挂接很多设备。而通用串行总线（Universal Aerial Bus，简称USB）的出现，很好地解决了以上这些冲突，很容易就能实现低成本、高可靠性、多点的数据采集。-err

[Other] USB

Description: 在工业控制及测量领域较为常用的网络之一就是物理层采用RS-485通信接口所组成的工控设备网络。这种通信接口可以十分方便地将许多设备组成一个控制网络。从目前解决单片机之间中长距离通信的诸多方案分析来看，RS-485总线通信模式由于具有结构简单、价格低廉、通信距离和数据传输速率适当等特点而被广泛应用于仪器仪表、智能化传感器集散控制、楼宇控制、监控报警等领域。但RS485总线存在自适应、自保护功能脆弱等缺点，如不注意一些细节的处理，常出现通信失败甚至系统瘫痪等故障，因此提高RS-485总线的运行可靠性至关重要。

[GUI Develop] communicate

Description: VC++ 6.0做的一个串口通信程序，功能与串口调试助手类似。它可以实现两台电脑的串口之间或者一台电脑的两个串口之间互相收发数据。左上角可以通过下拉列表选择不同的串口，默认的是COM1，考虑到笔记本电脑上一般没有串口，用USB转RS-232转换器之后，其COM口一般不为COM1，所以在程序中不做死COM口而是可以在界面中选择COM口，单击“关闭串口”就停止数据的收发。“接收区”对接收到的数据进行显示，接收可以选择自动接收或手动接收，自动接收状态只有检测到有数据发过来就进行显示，不处于自动接收状态时单击“手动接收”就开始接收数据，再单击这个按钮就停止接收数据，清空接收区就把接收区的所显示的数据进行清空。对于要发送的数据，在“发送区”填写，单击“发送”就把发送区的数据发送出去，单击“清空发送区”就把发送区的数据清空。-VC++ 6.0 to do a serial communication program, function and serial debugging aids like. It can be achieved between the two computers or a computer serial port, two serial ports send and receive data between each other. The upper left corner by the drop-down list to select a different serial port, the default is COM1, taking into account the serial port on laptops generally do not use USB-RS-232 converter, the COM port is generally not as COM1, why not do in the program Death COM port but can select the COM port in the interface, click "Close serial port" to stop sending and receiving data. "Receiving area" dock to display the data received, the receiver can choose to automatically receive or manual reception, automatically receive the state data are issued only to detect over the conduct shows that is not in condition to automatically receive when you click "Manual Receive" began to receive data, and then click this button to stop receiving data, empty reception area put the reception
