Description
Technical field
The utility model belongs to a kind of broadcast receiver, relates in particular to a kind of public emergent event broadcast receiving system.
Background technology
In the world today, the Public crisis incident frequently takes place, and the existing natural disaster of these Public crisis incidents also has man-made calamity, and the natural disaster aspect is such as tsunami, earthquake, mud-rock flow, mountain torrents, volcano eruption, black heavy rain, hurricane etc. are arranged; The man-made calamity aspect is such as nuclear leakage, the blast of extensive chemical plant, extensive poison gas leakage, warning of war etc. are arranged.Whenever above-mentioned Public crisis incident takes place; Need carry out emergency evacuation, urgent danger prevention, emergency relief, no matter therefore be disaster-stricken crowd, or the rescue personnel; Total hope can obtain relevant the condition of a disaster information in the very first time, so that take the correct hedging or the measure of recovering early.
Though current social information communication channel is flourishing; There are TV, broadcast receiver, phone etc. to diffuse information, still, when people do not know that as yet the condition of a disaster is when (comprising dangerous situation); TV, broadcast receiver can not be in normally open; Can not carry yet, thus rely on TV merely, broadcast receiver, can't guarantee to notify relevant crowd in the very first time with the condition of a disaster; Though and mobile phone can be in normally open, also can carry owing to need only one to everyone dialing, thus also can't be in the extremely short time dialing notify all relevant everyone.Moreover; When the condition of a disaster takes place, often be accompanied by power supply, communication disruption or paralysis, thereby when the burst the condition of a disaster; Even present information spreading tools such as TV, broadcast receiver, phone; Also be difficult to the condition of a disaster message is propagated to the disaster-stricken common people or rescue personnel immediately, make them make accurate judgement and to take correct hedging or the measure of recovering, in the hope of reducing casualties or property loss in the very first time.
The utility model content
The purpose of the utility model is a kind of public emergent event broadcast receiving system to be provided overcoming above-mentioned shortcoming, and it can be propagated the condition of a disaster message to the common people or rescue personnel when being about to take place or suddenly the condition of a disaster taking place immediately.
Its purpose can realize by following scheme: this public emergent event broadcast receiving system comprises the first wireless signal receiver module, electronic switch trigger module, electronic switch, power module, radio broadcasting signal receiver module, loud speaker; The first wireless signal receiver module is connected to the electronic switch trigger module, and the electronic switch trigger module is connected to electronic switch, and electronic switch is triggered and opened or closed by the electronic switch trigger module; Power module is connected to radio broadcasting signal receiver module, loud speaker through electronic switch, and the radio broadcasting signal receiver module is connected to loud speaker, and loud speaker is driven by the radio broadcasting signal receiver module and broadcasts; Power module is also connected to the first wireless signal receiver module, electronic switch trigger module.
Be preferably, also be provided with alerting signal module, hand switch, power module is connected in series to the alerting signal module through electronic switch, hand switch.
Power module is provided with electric quantity monitoring and Tip element.
The utlity model has following advantage and effect:
1, the utility model can be carried by the rescue personnel, also can dispose the masses to the condition of a disaster prone district, advantages of small volume.Under normal circumstances, the first wireless signal receiver module, electronic switch trigger module are in normally open.When the burst the condition of a disaster, relevant departments or mechanism launch wireless signal, and the first wireless signal receiver module receives corresponding signal; Make the electronic switch trigger module send control signal to electronic switch; The triggering electronic switch is opened, so radio broadcasting signal receiver module, loud speaker are forced automatically and open, at this moment relevant departments or mechanism can send the broadcasting of the condition of a disaster message through the wireless frequency modulation signal; Behind the radio broadcasting signal receiver module; Broadcasted by loud speaker, the therefore disaster-stricken common people or rescue personnel can be known the condition of a disaster message in the very first time that is about to take place or take place suddenly the condition of a disaster, make them make accurate judgement and to take correct hedging or the measure of recovering in the very first time; Carry out emergency evacuation or emergency relief, to reduce casualties or property loss.
2, when the condition of a disaster message off-the-air, relevant departments or mechanism can launch wireless signal again, and electronic switch cuts out.
3, under normal circumstances, have only the first wireless signal receiver module, electronic switch trigger module to be in open mode, radio broadcasting signal receiver module, loud speaker then are in closed condition; Because the first signal wireless receiver module, electronic switch trigger module only are responsible for triggering electronic switch, signal is simple, signal is slight, thus they power consumption is slight under normal circumstances, help staying open for a long time state.And power module is provided with electric quantity monitoring and Tip element, helps guaranteeing to have for a long time.
4, can also be provided with alerting signal module and hand switch; Hand switch is opened under normal circumstances; Thereby be triggered when opening when electronic switch; The alerting signal module just be connected with power module and electric, can send alerting signal (for example flash of light or vibration), reminds people notes listening to the FM broadcasting of the condition of a disaster message.When people no longer need remind, can hand switch be closed.
Description of drawings
Fig. 1 is the circuit theory sketch map of a kind of specific embodiment of the utility model.
Embodiment
Shown in Figure 1, this public emergent event broadcast receiving system comprises the first wireless signal receiver module, electronic switch trigger module, electronic switch, power module, radio broadcasting signal receiver module, loud speaker; The first wireless signal receiver module is connected to the electronic switch trigger module, and the electronic switch trigger module is connected to electronic switch, and electronic switch is triggered and opened or closed by the electronic switch trigger module; Power module is connected to radio broadcasting signal receiver module, loud speaker through electronic switch, and the radio broadcasting signal receiver module is connected to loud speaker, and loud speaker is driven by the radio broadcasting signal receiver module and broadcasts; Power module is also connected to the first wireless signal receiver module, electronic switch trigger module.This public emergent event broadcast receiving system also is provided with alerting signal module, hand switch, and power module is connected in series to the alerting signal module through electronic switch, hand switch.In addition, power module is provided with electric quantity monitoring and Tip element.
