Civil air defense alarm system based on IP network broadcasting

Abstract

The invention discloses a civil air defense alarm system based on IP network broadcast, and belongs to the technical field of civil air defense alarm. The system comprises an alarm unified control center, an alarm terminal controller, an alarm terminal, an IP network broadcast server and a wireless network hotspot, wherein the alarm terminal is a lamp post type alarm; the alarm terminal controlleris connected with the IP network broadcast server and outputs audio to the IP network broadcast server. The IP network broadcast server is connected with the wireless network hotspot through a network and transmits audio data to the wireless network hotspot. The wireless network hot spot broadcasts audio data to an IP network sound post of the lamp post type alarm within the coverage of the wireless network hot spot through a wireless signal, the alarm terminal controller sends a control signal to an alarm unit of the lamp post type alarm in a wireless mode, and the alarm unit controls on-offof the IP network sound post according to the control signal. The audio of the alarm terminal is transmitted in a digital mode, the audio quality is guaranteed, distance limitation is avoided, infinite expansion can be achieved, deployment is convenient, and the alarm terminal is very practical.

Description

technical field [0001] The invention relates to a civil air defense alarm system based on IP network broadcasting, belonging to the technical field of civil air defense alarms. Background technique [0002] The light pole siren refers to a device that installs the civil air defense siren on the street light pole. It can be used for lighting at ordinary times, and can issue an alarm when it is necessary to issue an alarm. [0003] At present, there are two types of pole-type alarms in structure: pole-type and lodging-type. Among them, the lodging structure can lay down the light pole, which is convenient for the operator to repair and replace it. Current light post alarms generally include solar panels, energy storage batteries, charging control circuits, lamp holders, sound columns and other parts, but their sound columns generally use fixed resistance sound columns, which can only receive analog audio signals. [0004] In addition, the light pole-type alarm terminal in th...

Problems solved by technology

The current light pole alarms generally include solar panels, energy storage batteries, charging control circuits, lamp holders, sound columns and other parts, but their sound columns generally use fixed resistance sound columns, which can only receive analog audio signals

[0004] In addition, the light pole-type alarm terminal in the prior art usually uses analog audio to issue alarms, voice broadcasts, and music playback. The signal type it transmits is an analog signal, which is easily affected by factors such as voltage, power, and impedance. Poor, limited distance, difficult to expand and other limitations
