Description: 利用SPCE061A，RS485 多路数据采集系统
本系统采用双CPU控制，主机与从机的CPU都是使用SPCE061A单片机。从CPU负责采集七路数据，同时应答主CPU发送的命令。主CPU进行数据处理，数据显示，键盘输入，系统报警，语音播报通道的电压值。在主CPU与从CPU的通讯中，采用国际标准的RS485差分方式接口，使通讯的速率和传输距离均大于RS232的标准接口方式，并且用线最少（只要两根）。本系统实现了一种具有语音播报、语音提示的高性能、高智能的实用型远距离多路数据采集系统。-The use of SPCE061A, RS485 multi-channel data acquisition system using dual-CPU of the system control, the host machine s CPU from SPCE061A Singlechip use. From the CPU is responsible for collecting data on seven routes, while answering the main CPU to send commands. The main CPU for data processing, data display, keyboard input, the system alarm, voice broadcast channel voltage. In the main CPU and the communications from the CPU, using international standards, the way RS485 differential interface to enable communication rate and transmission distance were greater than the standard RS232 interface mode, and with lines at least (as long as 2). The system achieved a voice broadcast, voice prompts, high-performance, high intelligence, practical long-range multi-channel data acquisition system.

Description: RS-232、RS-422与RS-485都是串行数据接口标准，最初都是由电子工业协会（EIA）制
订并发布的，RS-232在1962年发布，命名为EIA-232-E，作为工业标准，以保证不同厂家产品
之间的兼容。RS-422由RS-232发展而来，它是为弥补RS-232之不足而提出的。为改进RS-232
通信距离短、速率低的缺点，RS-422定义了一种平衡通信接口，将传输速率提高到10Mb/s，
传输距离延长到4000英尺（速率低于100kb/s时），并允许在一条平衡总线上连接最多10个接
收器-RS-232, RS-422 and RS-485 serial data interface standards are the first by the Electronics Industry Association (EIA) and published in, RS-232 issued in 1962, named for the EIA-232-E, as the industry standard to ensure that different manufacturers of compatible products. RS-422 by the development of RS-232, which is designed to remedy the lack of RS-232 made. RS-232 to improve the short-distance communications, the shortcomings of low-rate, RS-422 defines a balance between communication interface transfer rate up to 10Mb/s, transmission distance was extended to 4000 feet (at rates of less than 100kb/s), the and allow the balance on a bus to connect up to 10 receivers
