摘要
介绍了芬兰VTI公司生产的SCA100T倾角计的特性,结构,工作原理以及与单片机SPI串行接口连接的工作模式、命令格式、操作方法,并给出了与单片机连接的双轴测量应用实例。具有结构简单、可靠性高、抗干扰能力强,不需要扩展外围器件等特点,根据不同需要可以应用于各种倾角,位移测控系统中。
Introduced the characteristic, internal structure and operation elements of the SCA100T inclinometer which belongs to the VTI technologies. The work mode, command format and operation method of the SPI serial interface are described. Some measurement application cases of 2-axis inclination measurement connected with the single-chip computer are also given. The system has the characteristics of simple structure , high reliability, strong noise resistances, no peripheral chip, etc, and may be applied many inclination, displacement measurement and control system.
