| 中文摘要: |
| 提出了基于CAN总线的轨道衡数据采集系统。系统以MAX187为模数转换器件，对传感器信号进行采样。采样值通过CAN收发器发送到CAN总线上，通过RS232接口输出到上位机。测试结果表明，利用CAN总线通信解决了通信误差大、通讯速度慢等问题，能够实现长期有效的快速传输，满足轨道衡实时数据传输的要求。 |

| This paper presents a track scale data acquisition system based on CAN bus.The system usesd the MAX187 as the ADC device to sample the signal of the sensor.The sample value is sent to the CAN bus by CAN transceiver to output it to the upper computer via RS232 interface.Testing results showed that it could solve the problems of large communication error and slow communication to realize long-term effective and rapid transmission to meet the requirements of the real-time data transmission of the track scale through CAN bus communication. |
