介绍了一种可用于化工过程状态远程监测的无线传输系统,并讨论了本地PCI Modem系统的实现。该Modem改变了当前存在的Modem系统取电不方便,不易携带的缺点,地域适用性更广。本文主要分析了系统硬件设计和软件设计,包括器件选型,桥接芯片OX16PCI954配置,硬件构成原理,驱动安装软件开发和应用软件设计等。实际使用表明,该Modem系统适应性较强,性能良好,稳定实用。
A wireless transmission system which can be used for remote monitoring of chemical process conditions is introduced. The realization of local PCI Modem system is also discussed. The Modem changes the shortcomings of the current Modem system that power is inconvenient to carry and is not easy to carry. The geographical applicability is broader. This article mainly analyzes the system hardware design and software design, including device selection, bridge chip OX16PCI954 configuration, hardware composition principle, driver installation software development and application software design. Actual use shows that the Modem system adaptability, good performance, stable and practical.
