Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the present invention, but do not indicate or imply that the device or element of the present invention must have a specific orientation, and thus, should not be construed as limiting the present invention.

Examples

Please refer to fig. 1, the utility model discloses a civil air defense emergency alarm, including MCU module, speaker, GPRS module, storage module and big dipper module. The loudspeaker is connected with the MCU module to send an alarm under the control of the MCU module; the GPRS module is connected with the MCU module and is communicated with an upper computer to acquire/update an alarm issuing plan; the storage module is connected with the MCU module to store the alarm issuing plan; the Beidou module is connected with the MCU module, returns a position to the upper computer and receives an instruction issued by the upper computer in a short message mode, so that when the Beidou module reaches a set position, the MCU module calls a corresponding alarm issuing plan and issues the alarm issuing plan according to the received instruction. In this embodiment, the big dipper module is the RDSS full function module.
