| titleOfInvention | Alarm device, alarm device failure detection method, railroad crossing alarm, and railroad crossing alarm failure detection method |
| abstract | An alarm device having a relatively simple circuit configuration and capable of recognizing the presence or absence of a failure even by a general person who has not undergone predetermined training. The alarm device includes an oscillation circuit and an oscillation circuit, and synthesizes and outputs an acoustic signal f1 transmitted from the oscillation circuit 21 and an acoustic signal f2 transmitted from the oscillation circuit 31. To do. From the failure detection oscillation circuit 12 for transmitting a failure detection acoustic signal f3 that is an acoustic signal different from the acoustic signals f1 and f2 transmitted from the oscillation circuit 21 or the oscillation circuit 31, and the failure detection oscillation circuit 12. The transmitted acoustic signal f3 is branched into two, one of the acoustic signals f3 is superimposed on the acoustic signal f1 transmitted from the oscillation circuit 21, and the other acoustic signal f3 is transmitted from the oscillation circuit 31. The phase is inverted and superimposed. [Selection] Figure 1 |
