Title:
SENSOR AND DISASTER PREVENTION SUPPORT SYSTEM
Document Type and Number:
Japanese Patent JP2018014044
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a sensor having power saving information transmission means capable of sharing a power supply part of the sensor configuring an automatic fire alarm facility.SOLUTION: A sensor 10 comprises: a communication part 18 for communicating with a receiver; an abnormality sensing part 12 for sensing abnormality; a warning part 13 for, when the abnormality sensing part 12 senses abnormality, causing the communication part 18 to transmit an abnormality signal to the receiver; a storage part 14 for storing information to be transmitted to the periphery as transmission information; a control part 15 for transmitting a control signal for transmitting the transmission signal read from the storage part 14; a modulation part 16 for changing an impedance in accordance with the control signal; and a transmission body 17 connected to the modulation part 16 for modulating and reflecting an electromagnetic wave from a radio wave transmission device on the basis of a change in the impedance, therein a peripheral mobile device is allowed to receive the radio wave modulated and transmitted by the transmission body 17, and to acquire the transmission information.SELECTED DRAWING: Figure 2
