Abstract
The utility model discloses an ad hoc network voice transmission system. The ad hoc network voice transmission system comprises a microphone and a voice compressor which is connected with the microphone, wherein the voice compressor is connected with a signal transmitter; the signal transmitter is connected with a signal receiver through a wireless ad hoc network; the signal receiver is connected with a demodulator; the demodulator is connected with a speaker; and the wireless ad hoc network is a distributive wireless network capable of realizing cascade extension. The ad hoc network voice transmission system has the advantage that the network has independence, anti-interference performance and safety, and is high in data transmission rate and low in cost.
Description
Technical field
The utility model relates to a kind of voice-transmission system, relates to a kind of ad-hoc network voice-transmission system in particular.
Background technology
Natural calamities such as earthquake, mud-rock 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 natural calamity 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.Existing disaster alarm mainly adopts voice-transmission system, is used to transmit disaster early-warning information.Its signal transmission form generally adopts cable network or wireless form.Though the signal of cable network transmits stability height, good reliability, the building of cable network, maintenance and operation cost are higher.Though wireless network to a certain extent its to build cost not high, the stability that its signal transmits has certain limitation, and it need give the certain Internet utilization fee usefulness of network provider, has increased its cost to a certain extent.
The utility model content
The utility model provides a kind of ad-hoc network voice-transmission system, and it utilizes ad-hoc network to be its transmission that signal is provided, and it is lower to make its network have independence, anti-interference and fail safe, message transmission rate height, cost.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of ad-hoc network voice-transmission system, it comprises microphone and the Sound compressor that is connected with microphone, described Sound compressor is connected on the control main board, described control main board also is connected with signal projector, described signal projector is connected with signal receiver by wireless ad hoc network, described signal receiver is connected with the early warning mainboard, also be connected with loud speaker on the described early warning mainboard, described control main board comprises audio process and modulator, and described early warning mainboard comprises demodulator and amplifirer.
In native system, adopt ad-hoc network to carry out the transmission of voice signal for it.The advantage of wireless ad hoc network: it is lower that network has independence, anti-interference and fail safe, message transmission rate height, cost.The support that its independence is embodied in it can be at any time, any place does not need the hardware foundation network facilities can be set up a mobile communications network fast, has very strong independence.Its anti-interference and fail safe is embodied in: owing to adopt height frequency self-adaption mechanism, reduced that adjacent wireless signal is crosstalked and other air interference sources influence that data are communicated by letter in the air.The wireless data of wireless ad hoc network system adopts dynamic frequency hopping and frequency self-adaption mechanism, has high-intensity confidentiality.
Further technical scheme is:
But described wireless ad hoc network is the wireless network of distributed cascade expansion.
Described wireless ad hoc network is made up of a plurality of wireless sensor networks.
Described wireless sensor network adopts JZH-0xx series.
Described Sound compressor adopts DBX160A, 160X, 166XL, 266XL, 1066.
Described loud speaker is a dynamic speaker.
Described signal receiver is HC-RW01.
In the utility model, microphone sends to Sound compressor with the voice messaging of collecting, Sound compressor is handled voice signal, and sending it to control main board, control main board is carried out voice messaging after modulation makes it satisfy condition that signal transmits and will handle to voice signal and is sent signal projector to and send.Disaster early warning system distance general and the early warning center is far away.Because the signal transmitting boundary of signal projector is less, make signal receiver can receive voice messaging, then middle employing wireless self-help network provides the transmission service of voice signal for it.Wireless ad hoc network sends voice signal to signal receiver, and signal receiver sends to the early warning mainboard with the voice signal that receives and separates the mediation power amplification, makes voice signal satisfy the needs of loudspeaker plays, sends voice signal to loudspeaker plays again.
Compared with prior art, the beneficial effects of the utility model are: it adopts wireless ad hoc network to be its transmission that disaster alarm voice signal is provided, and it is lower to make its network have independence, anti-interference and fail safe, message transmission rate height, cost.
