IBM—PC与Intel8031构成的两级微机控制系统的数据通信

Data Communication of Two-level Microcomputer Control System Composed of IBM-PC and Intel 8031

提供能满足实时控制要求的可靠的数据通信,是实现两级微机控制的一个技术关键。本文提出一种低成本的数据通信方案,并详细讨论其通信网络结构、通信控制与管理方式、数据表示形式与相互间转换以及提高可靠性的有效措施。测试结果表明,该通信系统简单、可靠,能满足实时控制要求。

To provide reliable data communication which can meet the requirements of real-time control is a technical key problem when two-leve microcomputer control is put into action. In this paper the data communication scheme of low cost is presented, and the structure of communication network, the mode of communication control and management, the represented forms of the data and the conversion between themselves and effective measures to improve reliability are discussed in detail. Test results demonstrated that the data communication system which is simple and reliable can meet the need of real-time control.
