Description

Technical Field

[0001] The utility model relates to the technical field of public safety equipment, in particular to an electroacoustic alarm integrated machine with an automatic relay function. Background Art

[0002] Most of the existing air defense sirens adopt wireless data transmission radios, which use special frequency points for civil air defense sirens to directly conduct two-way data communication with a remote control center, and the equipment itself does not have a forwarding function. With the rapid development of urban construction, the urban scale has gradually expanded, there are more and more high-rise buildings, and the urban electromagnetic environment noise is getting larger and larger. Moreover, the electromagnetic wave transmission in space is affected by terrain and urban electromagnetic noise interference, resulting in a reduction in the communication distance of the wireless data transmission radio. The air defense sirens installed at a relatively far position cannot receive the alarm signals transmitted by the remote control center, thus restricting the remote control of the air defense sirens.
