Description
Technical field
the present invention relates to a kind of speech amplifier, especially relate to a kind of can wireless receiving and broadcast early warning speech amplifier.
Background technology
in recent years, due to the combined influence of mankind's activity and natural cause, global climate is in warming trend year by year, irregular anomalous weather continues to bring out on a large scale, Extreme Weather Events frequently occurs, bring significant impact and destruction to socio-economic development, people life property safety, the ecologic environment also making the mankind depend on for existence suffers direct threat.Holding of " Copenhagen World Climate Conference ", confirms that national governments and international body all pay much attention to this, and reply complexity, changeable climate environment have become the important topic concerning the mankind, concern the world.
china is vast in territory, physical features is complicated, monsoon climate is obvious, the disaster that Extreme Weather-climate Events causes is relatively frequent, heavy rain, flood, arid, damage to plants caused by sudden drop in temperature, freeze injury, cold damage, severe snow, hail, dense fog, thunderclaps, spout, strong wind, heat wave, sandstorm, hot dry wind, cloudy weather for several days running, the meteorological disaster such as tropical cyclone happen occasionally.Especially in recent years weather is often gone to extremes, meteorological disaster presents the feature that kind is many, scope is wide, intensity is large, the loss that meteorological disaster causes every year accounts for about 70% of whole disaster, the direct economic loss caused accounts for about the 3-6% of GDP, utilize technological means to prevent and reduce natural disasters, become the important administration content of governments at all levels, water conservancy bureau, Meteorological Unit, Radio & Television Bureau, able to resisting flood and drought office etc.
along with rural economic development and life of farmers level improve, agricultural, rural area, the demand of peasant to weather information particularly diastrous weather information sharply strengthen, but still aobvious single for the weather information means of rural area and peasant, affect carrying out of rural area disaster prevention and relief work to a great extent.Construction of rural meteorological disaster early warning broadcast platform, installing weather warning LED display and meteorological calamity emergency broadcast system, is the infrastructure construction of reinforced region disaster prevention and relief, effectively improves the important channel of meteorological disaster pre-alerting ability.To rural area, " typhon " is the most universal, most convenient, most economical, coverage rate is the widest, the pattern of " meteorological disaster early warning broadcasting receiver+typhon+display screen ", thoroughly solve the problem of weather information to rural area " last one kilometer ", greatly can improve the ability that peasant prevents and reduces natural disasters, bring huge agricultural performance.At present, the early warning speech amplifier on market is functional single, can not meet the need of market.
Summary of the invention
the object of this invention is to provide one, to have structure simple, reliable operation, and easy to operate, work efficiency is high, wireless transmission can report voice content, and can carry out a kind of of the advantages such as long distance wireless report can wireless receiving the early warning speech amplifier of broadcast.
in order to realize object of the present invention, the present invention is achieved by the following technical solutions: a kind of can wireless receiving and broadcast early warning speech amplifier, comprise early warning plane receiving end, wireless speech input end; It is characterized in that: described early warning plane receiving end comprises: power module, main control module, voice module, number electric modular converter, wireless receiving module, power amplifier module; Described wireless speech input end comprises: power module, main control module, voice module, number electric modular converter, wireless sending module; In described early warning plane receiving end: power module connects main control module, main control module connects voice module and power amplifier module, voice module linking number electricity modular converter, and the electric modular converter of number connects wireless receiving module; In described wireless speech input end: power module connects main control module, main control module connects voice module, voice module linking number electricity modular converter, the electric modular converter of number connect wireless sending module.
