摘　　要：介绍一种以DSP(数字信号处理器)为核心的油井液面测试系统。该系统控制声波发射器发射声波,接收传感器将回波信号转化为电信号后传送给DSP,然后DSP再根据预先设置的参数和相应的算法计算出油井液面深度。同时,该系统通过USB总线将测试数据传送到PC上位机,通过上位机监控软件查看测试数据。In this paper,an oil well liquid level measurement system based on DSP（digital signal processor） is introduced.The system controls acoustic transmitter to send sound wave.The receiving sensor converts the echo to electric signal and sends it to the DSP unit.Then the oil well liquid level is calculated with corresponding algorithm and the pre-set parameter by DSP.Contemporary,the test data are sent to the PC by USB bus and are checked through PC monitoring software.
