Abstract: A fire detector is connected to a loop transmission path connected to a receiver. When the loop transmission path is normal, a communication connection is made from a transmitting unit to the fire detector to monitor fire. When a break fault occurs in the loop transmission path, a break monitoring control unit turns switching circuit units ON to connect a termination of the loop transmission path to the transmitting unit. To the loop transmission path, a relay detects a current normal direction at normal and a current reverse direction at the time of occurrence of a break for transmission to the receiver. When a break occurs in the loop transmission path, a break section determining unit of the receiver determines, as a break section, a section in which the current normal direction detected by a plurality of the relays is changed to the current reverse direction.
Abstract: An electromagnetic wave from a transmitter (100) is emitted toward the outside of a first angular range (AR). A receiver (200) cannot detect an electromagnetic wave reflected at a position somewhat close to a sensor device (10), specifically, an electromagnetic wave reflected at a position apart from the sensor device (10) by less than a distance R1. Specifically, when the electromagnetic wave is reflected at the position apart from the sensor device (10) by less than the distance R1, the electromagnetic wave reaches the sensor device (10) before the first angular range (AR) reaches a Y axis. Consequently, the electromagnetic wave reflected at the position somewhat close to the sensor device (10) is not detected by the receiver (200).
Abstract: A measuring device (200) is a device disposed in a mobile body, and includes a measurement unit (202) that scans an object by emitting electromagnetic waves. The measurement unit (202) is controlled by a measurement unit control device (203) including a control unit (204). The control unit (204) sets a scanning range of the measurement unit (202) using information on a position that is a predetermined distance ahead. Specifically, the control unit (204) determines a position that is a predetermined distance ahead of the current position of the mobile body (240), on a predicted course of the mobile body (240). Further, the control unit (204) uses information on the position that is a predetermined distance ahead to set the scanning range of the measurement unit (202).
Abstract: A measurement device (200) includes a measurement unit (202) which performs measurement by emitting electromagnetic waves and scanning an object with the electromagnetic waves, and a control unit (204) which controls the measurement unit (202). The measurement unit (202) is operable in a first scan mode in which the object is scanned in a first direction, or a second scan mode in which the object is scanned in a second direction different from the first direction. The control unit (204) determines a scan mode to be executed by the measurement unit (202).
