    • The invention relates to a method and a device for monitoring a space for the presence of a foreign body. The monitoring device usually comprises at least one transmitter and a first and second receiving device. Conventional methods for evaluating the signals received by the receiving devices only allow for a limited statement as to whether the received signals possibly contain parasitic signal portions which would falsify an evaluation with respect to the presence of a foreign body. The aim of the invention is therefore to provide a method and device which improve the reliability of such a statement. For this purpose, the signal of the second receiving device which is spaced further apart from the transmitter than the first receiving device is evaluated for its parasitic signal portions. If the distance between the first and the second receiving device is not too great, it can be assumed that parasitic signal portions detected in the second received signal are also contained in the first received signal. In this case, it is recommended to discontinue monitoring the space or to discard any result of this monitoring already obtained at least until no parasitic signal portions are detected in a repeated evaluation of the second received signal.
    • 本发明涉及一种用于监测异物存在的空间的方法和装置。 监视装置通常包括至少一个发射机和第一和第二接收装置。 用于评估由接收装置接收的信号的常规方法仅允许对接收到的信号是否可能包含伪造关于异物存在的评估的寄生信号部分的有限说明。 因此,本发明的目的是提供一种提高这种陈述的可靠性的方法和装置。 为此,针对其寄生信号部分评估与发射机相比间隔得比第一接收装置间隔得更远的第二接收装置的信号。 如果第一和第二接收装置之间的距离不太大,则可以假设在第一接收信号中也包含在第二接收信号中检测到的寄生信号部分。 在这种情况下,建议停止对该空间的监视,或者丢弃迄今已经获得的任何监视结果,直到在第二接收信号的重复评估中没有检测到寄生信号部分。
