Ultrasonic sensor to form a sensor arcade and sensor arcade of ultrasonic sensors

摘要

The present invention concerns an ultrasound sensor (12, 14),in particular as part of an ultrasonic monitoring system (1) with several ultrasonic sensors located in a cascade (10) for a vehicle, with a supply voltage connection (16) for connecting to a DC supply line (18),a mass connection (20) for connecting to mass (22),an input communication line connection (24) to connect to a first segment (26) of a communication line (28),in particular to monitor the reception of signals during an initialisation, an output communication line connection (30) to connect to a second segment (32) of the communication line (28),in particular for the transmission of signals during an initialisation, and a connection unit (36) for the interconnection of the incoming communication line connection (24) and the outgoing communication line connection (30),where the ultrasonic sensor (12, 14) is designed to perform an initialization as master or slave in the cascade (10) depending on the reception of an initialization signal, the ultrasonic sensor (12) as master controls the cascade (10), the ultrasonic sensor (14) as a slave transmits a signal corresponding to a sensor input (28) and the ultrasonic sensor (14) as the last slave transmits an output signal corresponding to the sensor input received on the cascade (10), with the ultrasonic sensor (12, 14) set up for this purpose; operate the connection unit (36),to connect the input communication line connection (24) and the output communication line connection (30) after receiving the initialisation signal. The present invention also concerns an appropriate ultrasound monitoring system (1),which has several of the above ultrasound sensors (12, 14).
