The technical scheme that its technical matters that solves the utility model adopts is: the intelligent electric sound alarm, it is that panel is arranged on casing, two loose-leaves are arranged on one side, tank floor has the power lead of drawing, and there is control panel the panel the inside, there are voltage table, reometer in the left side, there are two display windows on the right, handle is arranged below the display window, and microphone, volume adjusting, MP3, acoustic control, inside and outside selection, switch are arranged bottom from left to right successively, wiring board is arranged at bottom, casing the inside, and there is stator the outside for four jiaos.The block scheme of control panel circuit, there is main control unit on the left side, and the right has voltage table, reometer, Audio Processing from top to bottom successively, and bottom has the button input to show.The block scheme of bottom, casing the inside wiring board, the left side has primary power, amplifier power supply, power supply hand-off process plate from top to bottom successively, and there is power amplifier on the right.
During the start of intelligent electric sound alarm, control panel self check, work indication Chang Liang.Just often, relay indicating light glimmers after the self check, flicker frequency 1 second 1 time, and when equipment alarm, according to different categories within police force, corresponding pilot lamp is glittering, and equipment is in when amplifying state in addition, and In-use indicator is glittering.Behind the EO, recovering state.
Principle is: this intelligent electric sound alarm, can be reasonably according to input allocating task amount, two CPU can both handle sound, can both pilot relay, and increased synchronization mechanism, coordinates the consistance that two CPU work.
The beneficial effects of the utility model are, this intelligent electric sound alarm adopts two CPU designs to increase the ability of dynamic process tasks, a CPU checking another one CPU result, and operation is normal, and the result is just arranged, and has improved the reliability that complete machine is exported like this.
