Abstract
The utility model discloses a dual-power-supply wireless early-warning single-station terminal including a shell. An early-warning control mainboard is embedded in the shell. The early-warning control mainboard includes a signal processing circuit, a microcontroller and a power amplifying circuit. The signal processing circuit and the power amplifying circuit are both connected to the microcontroller. The microcontroller is connected with a power adapter. The microcontroller is also connected with a storage battery. A reminder lamp is also connected to the microcontroller. The dual-power-supply wireless early-warning single-station terminal has an advantage that the occurrence of power failure can be prevented by adopting a multi-power-source method for supplying power for the dual-power-supply wireless early-warning single-station terminal.
Description
Technical field
The utility model relates to a kind of wireless alarming list station terminal, relates to a kind of dual power supply wireless alarming list station terminal in particular.
Background technology
Disasteies such as earthquake, rubble flow, landslide, extreme weather have brought serious threat for people's lives and properties, are also restricting people's economic development.Therefore, all departments such as governments at all levels, weather bureau will utilize technological means to set up and prevent and reduce natural disasters early warning system as the emphasis of working.For the property safety of protecting people and the safety of life, easily send out the zone in disaster and set up radio broadcasting early warning main website, be convenient to the disaster alarm message very first time known by people, make people carry out the work of preventing and reducing natural disasters ahead of time, reduce the loss of disaster as far as possible.But because the alpine terrain complexity, its powering-off state happens occasionally, and when outage, its wireless alarming list station terminal can not be worked, and influence its warning function.
The utility model content
The utility model provides a kind of dual power supply wireless alarming list station terminal, and its mode that adopts many power supplys is the terminal power supply of wireless alarming list station, makes it can prevent the generation of powering-off state.
For solving above-mentioned technical matters, the utility model by the following technical solutions:
Dual power supply wireless alarming list station terminal, it comprises housing, described housing is embedded with early warning control mainboard, described early warning control mainboard comprises signal processing circuit, microcontroller and power amplification circuit, described signal processing circuit and power amplification circuit all are connected on the microcontroller, described microcontroller is connected with power supply adaptor, and described microcontroller also connects accumulator, also is connected with warning light on the described microcontroller.
In the utility model, utilizing power supply adaptor, make its available 220V AC power directly power; When outage, microcontroller directly utilizes storage battery power supply.When outage, power supply mode becomes storage battery power supply by the 220V ac power supply, and this moment, microcontroller was lighted warning light, and warning light is light, to give the staff to remind, so that in time change battery when accumulator electric-quantity is not enough.
Further technical scheme is:
Described power supply adaptor is connected on the 220V power supply.
Be connected with audio output interface on the described power amplification circuit.
Be connected with loudspeaker on the described audio output interface.
Loudspeaker is used for early warning information is reported out, and sound was loud and clear when it was reported, and can allow more people arouse vigilance.
Described warning light is the LED lamp.
Because the electric weight of accumulators store is limited, in order to be power devices for a long time, is the energy-saving LED lamp of low-power consumption so select warning light for use.
Described microcontroller is E7500.
Compared with prior art, the beneficial effects of the utility model are:
1, the utility model utilizes 220V AC power and the power supply of accumulator dual mode, and accumulator can continue when outage takes place to the utility model power supply, to avoid the generation of special circumstances.
2, LED lamp of the present utility model can point out people in time to change the abundant accumulator of electric weight.
3, of the present utility model simple in structure.
