Digital sound column installed on concrete pole

Abstract

The invention discloses a digital sound column installed on a cement electric pole, which comprises a cuboid-shaped outer casing (1) and an internal circuit, the front of the outer casing (1) is provided with a speaker, and the outer The back of the housing (1) is provided with heat dissipation louvers (2), the top of the external housing (1) is provided with an antenna device, and the bottom of the external housing (1) is provided with cooling holes; the internal circuit includes an audio control unit and Heat dissipation control unit; the audio control unit includes a first controller and a power amplifier; the heat dissipation control unit includes a temperature sensor, a second controller, and a heat dissipation fan; the heat dissipation fan is arranged at a position corresponding to the heat dissipation hole. The digital sound column of the invention is suitable for an emergency broadcasting system, and realizes audio playback control and heat dissipation control.

Description

technical field [0001] The invention relates to the field of emergency broadcasting systems, in particular to a digital sound column installed on a cement pole. Background technique [0002] When encountering public emergencies or special events, the command personnel need to use the broadcast system for emergency broadcasting to implement emergency command and information release. In the traditional emergency broadcasting system, the commander needs to enter the broadcasting room to turn on the broadcasting equipment before broadcasting. Due to the low efficiency of this emergency broadcast system, it is easy to delay the best time to deal with emergency events, so people began to seek remote control of the emergency broadcast system. When remotely controlling the emergency broadcast system, even if the commander is far away from the incident, the emergency broadcast system can be activated as soon as the incident occurs, so as to carry out emergency command and informatio...

AI Technical Summary

Problems solved by technology

However, the existing sound column usually only has a power amplifier function, and due to the high power of the sound column equipment, the probability of damage to the internal circuit of the sound column is relatively large without a heat dissipation structure; and because the sound column usually Installed outdoors, only setting the internal temperature sensor cannot detect the high heat caused by the external environment
