Technical Field
The utility model belongs to the public service field, more specifically the utility model relates to a public emergency broadcast alarm device that says so.
Background
For scenic spots, parks, factories, business districts or other public places, some sudden events often easily occur, for the events, the monitoring personnel usually find the events and then process the events or find the events through field personnel and then correspondingly process the events, because the field personnel are not fixed, the situation that personnel find the events every time the abnormal events occur cannot be guaranteed, blind spots exist in monitoring, the number of the monitoring personnel is limited, the abnormal events cannot be found in time, and therefore the processing personnel cannot obtain related information at the first time, the event processing time is delayed, the optimal event processing time is finally missed, and great loss or casualties are caused; meanwhile, the existing devices can only carry out corresponding processing mechanisms according to events after the events occur, and cannot analyze and prejudge the events to be occurred. Therefore, the prior art has the defects of weak data acquisition capacity, low abnormal event processing speed, incapability of alarming the emergency event and incapability of avoiding the personal conflict between the on-duty personnel and the destructor.
Disclosure of Invention
The utility model discloses can convey the mode of reporting an emergency and asking for help or increased vigilance through equipment speaker to ensure recognition safety, realized that few station of people and public facilities place remind, illegal intruder has avoided the personnel on duty with illegal intruder's front contact, has avoided the personal conflict.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: public emergency broadcast alarm device include camera 1, infrared induction alarm 2, speaker 3, time delay relay 4, video cassette recorder 5, infrared ray alarm host 6, microphone 7, megaphone 8, 1 output of camera and video cassette recorder 5 input link, 2 outputs of infrared induction alarm are connected with infrared ray alarm host 6, 2 control ends of infrared induction alarm and time delay relay 4 both way junction, the output of microphone 7 is connected with 8 inputs of megaphone, 8 control ends of megaphone and 4 both way junction of time delay relay, 8 outputs of megaphone are connected with speaker 3, 3 start control ends of speaker and 4 both way junction of time delay relay, time delay relay 4's power supply section and commercial power input connection.
Preferably, the public emergency broadcast warning device further comprises an emergency control module 9, the emergency control module 9 is in two-way connection with the control end of the loudspeaker 8, and the emergency control module 9 is in two-way connection with the control end of the infrared alarm host 6.
Preferably, the utility power input end adopt resistance and electric capacity to constitute a complete rectifier bridge structure, camera 1, speaker 3, infrared induction alarm 2 have two sets, can realize the control and the information acquisition of two cameras 1, two speakers 3, two infrared induction alarms 2.
The utility model discloses beneficial effect:
the utility model discloses can convey the mode of reporting an emergency and asking for help or increased vigilance through equipment speaker to ensure recognition safety, realized that few station of people and public facilities place remind, illegal intruder has avoided the personnel on duty with illegal intruder's front contact, has avoided the personal conflict.
