Description

The emergency communication device

The utility model relates to the communication of a kind of radiophone relaying, and communication transmitted by the lift-off balloon of doing to meet an urgent need and the signal demonstration is used.It comprises following architectural feature, with low power radio retransmission unit, code signal display lamp connection hydrogen balloon hangs and is raised to the high-altitude, the radio relay contact is opened in relay immediately, can open by the instruction lamp that terrestrial wireless telephone set coding will go up to the air simultaneously, according to the Show Color coding, show commander's signaling.

In the Japan ICOM company product, disclose IC-RP1510 type radio telephone repeater technology, its purpose is to establish the topped fixing communication context of platform in the fixed location, and formation is to contain rectifier power source receiving element and transmitter unit, (emission 25-50W) volume is big, about 20 kilograms of weight.Weak point is only to be fit to do the ground fixed relay use.But the scene of disaster and unexpected incidents for example in case of emergency, not necessarily mobile communication in the topped scope of the repeater that has set up, the ultrashort wave phone can't be got in touch with the distant place, if more will make troubles to take action (particularly large quantities of personnel) owing to the information transmission is ineffective at night.

The design's purpose be to avoid above-mentioned weak point of the prior art and provide a kind of can fast lift-off be topped at any time wants topped zone with repeater, and the product of tangible commander's signaling is arranged.

The design's purpose can reach by following measure: low powered radio forward relay device and code signal instruction color lamp are cared on the hydrogen balloon lift-off device with line, the audio output line of low powered radio relaying retransmission unit is connected to code signal instruction lamp input, has designed the aerating device that emergent chemicals is made hydrogen in addition.

The drawing of accompanying drawing is described as follows:

Fig. 1 is that the application drawing of emergency communication device: C cares for low powered radio relaying retransmission unit f under the hydrogen balloon, cares for code signal instruction lamp D under the f ₁-D ₃, D ₁-D ₃Under care for antenna H and stay cord g.

Fig. 2 is that low powered radio relaying retransmission unit connects schematic diagram with code signal instruction lamp, and B is audio decoder driver, D ₁-D ₃Be color lamp, E is a battery, and A is the relaying retransmission unit, and IN is an audio output line, and S, K, J are audio decoder driver B output line.

It is the relaying retransmission unit that Fig. 3 separates driver electrical schematic diagram: A for audio frequency, and IN is the audio frequency pipeline.IC1 MT8870 is the dtmf decoder chip.S, K, J are the driver output line from bidirectional triode thyristor, D ₁-D ₃Be three color lamp.

The design does a step below in conjunction with accompanying drawing embodiment and sets forth:

Among the figure one, this device is by nylon rope g tractive hydrogen balloon C, and hydrogen balloon is cared for relaying retransmission unit f by nylon rope, and the relaying retransmission unit is cared for code signal instruction lamp D by nylon rope and electric wire again ₁-D ₃, care for antenna h again under the code signal instruction lamp.Antenna has thin and tall frequency cable to link to each other with the relaying retransmission unit in addition.

Among the figure two, the signal that relaying retransmission unit A receives enters audio decoder driver B by IN line output DTMF double-tone frequently, exports three road high level or low level from J, K, S respectively through the B decoding, drives code signal instruction lamp D ₁-D ₃, make D ₁-D ₃Lamp is bright or do not work, and finishes the coding indication work of lamp.

Among the figure three, the signal that relaying retransmission unit A receives by IN line output DTMF double-tone frequently, entering the IC1 model is the dtmf decoder chip of MT8870, IC1 decoding back output three road high level or low level, these three road level drive IC, 2 integrated circuit flashers, IC2 output are exported through No. three bidirectional triode thyristors respectively and are received each s, k, the J line is controlled D ₁-D ₃Bright or the coding indication work that do not work and finish lamp of lamp.Every bulb has continuous the connection with the high frequency cable screen with this complete set of having finished the emergency communication device of an electrode to connect.Low powered radio forward relay device adopts finished product receiving element plate and transmitter unit plate also can adopt the same frequency conversion board of finished product.Adopt with conversion board frequently and only use an antenna, adopt alien frequencies conversion board frequency difference two antennas far away of will trying one's best to leak with Thin cable and make.

The device that chemicals is made hydrogen filling balloon is to use the steel cylinder and the steel cylinder lid that meet the safe pressure condition to form.Steel cylinder has covered charging valve and gas ducting and earth connection (preventing static).Putting into chemicals in use adds entry and screws steel cylinder lid.Balloon inflation.Inflate the valve-off that finishes and tie up the balloon mouth with thin nylon rope.Instruct lamp, antenna to be connected with relaying retransmission unit and code signal then, whole emergency communication device just can be formed.

Being equipped with the Preparation of Hydrogen generator of being prepared by chemicals and inflation steel cylinder at ordinary times on the automobile, is unsafe owing to load hydrogen gas tank on automobile.It is very dangerous to meet traffic accident, so the method that native system adopts chemicals to add water disposes hydrogen filling balloon when promptly using immediately, carries out remote relay communication, because balloon can rise 100 to thousands of rice, the communication wide coverage is expansion.Bring into play effect at short notice highlightedly.If the code signal received of transponder is separated by decoding driver B and translated the corresponding pulses electric current in addition, drive red, green, yellow tri-colour LED D ₁-D ₃Flash, tri coloured lantern can be compiled out seven kinds of states, instruction such as can represent forward-reverse, stop.In the night masses or relevant personnel identification signal rapidly, carry out corresponding work and step.This power supply adopts cadmium nickel storage battery or other high-efficiency battery, and full device is comparatively simple.Shortcoming is to have thunderstorm hour to discharge.Get rid of these factors, service time and use still are a lot.It is fully possible implementing this utility model.

The design has following advantage compared to existing technology;

1, flexible, motor-driven, owing to only adopt the low powered radio relay forwarding, volume weight is big The big minimizing just is suitable for caring for lift-off with hydrogen balloon. Because balloon can rise to 100 to thousands of meters high Sky also can be topped far though power is little. Make the emergent logical of vehicle-mounted or portable several wooden cases dress The news device is fit to natural calamity, the emergency of unexpected incidents very much.

2, made more than the radio telephone repeater code signal instruction lamp function, especially when have natural calamity and accident night, can be according to the signal command action, this only depends on radiophone to accomplish in some occasion.
