摘　　要：介绍了一种基于TMS320F2812 DSP、仪表放大器的传感器数据采集系统的设计。传感器信号调理是对传感器直接输出的信号进行调节,信号调理的原理以及硬件实现电路在文中都做了说明。给出了DSP和传感器信号调理电路的接口设计;同时,结合作者实际工作的一个成功应用TMS320F2812 DSP与仪表放大器以及同步采样16 b ADC通过CPLD硬件接口的实例。通过验证此电路系统有非常好的性能和可扩展性。This paper introduces a kind of design based on TMS320F2812 DSP and IN - AMP in sensor data collection system. Sensor signal adjustment is used to adjust the direct output signal of sensors. The principle of signal adjustment and the hardware circuit implementation are both discussed in this paper. It applies the design of interface between DSP and sensor signal adjust circuit. Meanwhile,it produces the example that the TMS320F2812 DSP integrated with IN - AMP through using CPLD and 16bit ADC successfully by hardware based on my work.
