| 摘 要： | 地震监测系统常常使用串口异步通讯监测数据、传输命令，但由于核心器件所带的串口数量不足，通常需要扩展串口。提出以TL16C754B为核心器件的多串口数据采集方法，包括具体的系统电路的设计方法和部分驱动的编程源代码。由于该设计具有成本低、稳定性高、低耗、抗干扰能力强、电路简单等优点，已被成功地运用于微动台阵观测仪器中。

| Abstract: | Universal Asynchronous Receiver Transmitter(UART) is widely used in earthquake monitoring system to monitor data and transmit command.Because of the insufficient quantity of serial ports of some core devices,multiple extended serial ports are needed.A method based on TL16C754B to expand multiple serial ports is proposed and the design of systems circuit and source code are put forward.This design has several advantrages: low cost,high steady,low power,anti-interference ability,compact circuit,etc.so is succ... |
