用于运行超声波传感器的方法以及相应的超声波传感器
摘要：
本发明提出超声波传感器在双工运行中的运行。这通过用于在双工运行中运行超声波传感器的方法、相应的超声波仪和超声波传感器控制装置(21)实现。用于触发声学发送信号(25)的发送触发信号通过第一双工通道(23)以超声波传感器(22)的超声波换能器(224)的数倍谐振频率由控制装置(21)传送给超声波传感器(22)(S1)；发送触发信号通过分频装置(222)在超声波传感器(22)中分频到换能器谐振频率(S2)；基于声学渡越时间和在物体上的反射而比声学发送信号(25)延迟的至少一个声学接收信号(26)通过超声波换能器转换成电接收信号并通过第二双工通道(24)以超声波换能器(224)的谐振频率从超声波传感器(22)传送给控制装置(21)(S3)。
摘要（英）：

The invention provides operation of an ultrasonic sensor in duplex mode, which is realized by a method for operation of an ultrasonic sensor in duplex mode, a corresponding ultrasonoscope and a control device (21) of the ultrasonic sensor. A transmission trigger signal for triggering an acoustic transmitted signal is transmitted from the control device (21) to the ultrasonic sensor (22)(S1) via a first duplex channel (23) at a multiple of a resonance frequency of an ultrasonic converter (24) in the ultrasonic sensor (22); the transmission trigger signal is demultiplied to the resonance frequency (S2) of the converter in the ultrasonic sensor (22) through a dividing device (222); based on acoustic transit time and reflection of the object, at least one acoustic receiving signal (26) delayed than acoustic transmitting signal (25) is converted into electric receiving signal by the ultrasonic converter and is transmitted to the control device (21)(S3) from the ultrasonic sensor (22) with the resonance frequency of the ultrasonic converter (224) via a second duplex channel (24).
