摘要
针对工业领域环境复杂、需要采集和传输的数据量大、实时性要求高的特点,开发了一种基于PXA322与CAN总线的手持式工业检测终端。该系统以性能先进的PXA322嵌入式处理器为CPU,采用CAN控制器SJA1000和收发隔离器CTM1050搭建CAN网络硬件。该手持终端可用于各种支持CAN接口的工业现场,对设备运行状态进行监控、检测以及诊断等,实现了对工业现场数据的采集与传输,并保证了实时性、可靠性以及传输距离。
Aiming at the characteristics of complex environment, large amounts of data acquisition and transmission and high re- al-time demand in industrial areas, a kind of handheld industry detection terminal was developed based on PXA322 and CAN bus. In the system, the CPU was the advanced PXA322 embedded processor, CAN controller SJA1000 and CTM1050 transceiver isolator were used to set up the system hardware. The terminal can be used for a variety of industrial fields which support CAN interface, to monitor and detect the equipment running status, to achieve industrial field data collection and transmission. And the high real-time, reliability and transmission distance are ensured.
