Description
Technical field
The utility model radio broadcasting calling talkback terminal, belongs to communication technique field.
Background technology
At present, a lot of enterprise, such as thermal power plant, coal coal preparation plant, steel plant and port and pier etc. have work under bad environment and the industry characteristic such as staff's mobility is large, in order to effectively solve the Communication with this industry production feature, traditional scheduling communications system (without antinoise broadcast capability) can not meet enterprise's Production requirement, some industrial and mining enterprises is in order to solve the Communication of mobile personnel, use broadcast call system, but present anti-explosion telephone exists to be built, safeguard inconvenient, emergency communication cannot be carried out under power-off condition, unsafe factor is brought to production, existing access way be each terminal adopt be independently cable connect, cable itself is easily aging, perishable, communication line can be caused to interrupt and loose contact, terminal cannot normally be used, and be not easy to safeguard, difficulty of construction is high, installation cost is large, therefore, be necessary to be improved.
Utility model content
In order to overcome the deficiencies in the prior art, provide a kind of radio broadcasting calling talkback terminal that a kind of cost is low, convenient for installation and maintenance.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
Radio broadcasting calling talkback terminal, comprise shell, wireless receiving module, wireless transmitter module, voice input module, signal amplification module, power module, back-up source module, incoming line and loud speaker, wireless receiving module, power module, back-up source module are connected successively with voice input module, and wireless transmitter module, power module, back-up source module, signal amplification module are connected successively with loud speaker.
Described power module is connected with incoming line.
Described shell adopts explosion-proof, dust-proof, waterproof material.
Described wireless receiving module and wireless transmitter module adopt 137MHz-167MHz, 403MHz-423.5MHz common frequency band.
The beneficial effect that the utility model is compared with prior art had is:
1, the utility model by wireless access way avoid the instability of circuit, communication cable cost high and difficulty of construction is large; Use advanced communication support, by the protocol conversion of wireless communication mode, make equipment stability and safety more.
2, the utility model takes wireless transmission method, constructs more more convenient than cable, does not have cable cost, and construction is simple.
3, the utility model takes wireless access way, use the transmission of 137MHz-167MHz, 403MHz-423.5MHz common frequency band, interference can not be caused to miscellaneous equipment, use complex environment being not easy to unwrapping wire is wireless, makes I&M convenient, quick.
4, the utility model takes back-up source, can also continue in the event of a loss of power to use, and improves the safety and reliability of production.
Accompanying drawing explanation
Below by accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is connection diagram of the present utility model.
1 be shell, 2 be wireless receiving module in figure, 3 be wireless transmitter module, 4 be voice input module, 5 be signal amplification module, 6 be power module, 7 be back-up source module, 8 be incoming line, 9 for loud speaker.
Embodiment
The utility model will be further described by reference to the accompanying drawings for embodiment below.
As shown in Figure 1, radio broadcasting calling talkback terminal, comprise shell 1, wireless receiving module 2, wireless transmitter module 3, voice input module 4, signal amplification module 5, power module 6, back-up source module 7, incoming line 8 and loud speaker 9, wireless receiving module 2, power module 6, back-up source module 7 are connected successively with voice input module 4, and wireless transmitter module 3, power module 6, back-up source module 7, signal amplification module 5 are connected successively with loud speaker 9.
Described power module 6 is connected with incoming line 8.
Described shell 1 adopts explosion-proof, dust-proof, waterproof material.
Described wireless receiving module 2 and wireless transmitter module 3 adopt 137MHz-167MHz, 403MHz-423.5MHz common frequency band.
The utility model system introduces the advanced technologies such as wireless transmission, digital noise reduction, signal transacting, voice de-noising, Echo Cancellation by wireless receiving module 2 and wireless transmitter module 3, well overcomes tradition and to amplify the shortcomings such as talk-back host terminating machine is uttered long and high-pitched sounds, cross-talk, noise are large; Adopt radio connection, as system amplify dispatching host machine use.
This equipment has anti-noise function, can clear call under 120dB high noisy adverse circumstances, there is intelligent filtering on-site noise function, the noise at scene can not be passed to the other side, make the clear call of both sides, and also have according to instruction Auto Power On, automatic hand-up, automatic amplification, the functions such as intercommunication, the power that amplifies can reach 15-25W.
Terminal words station shell adopts Modular Structure Design formed by stretching steel plate, has easy to maintenance, and has better protective effect; Exquisite appearance, streamlined, have waterproof and dustproof, preventing destructing performance, surperficial baking vanish adapts to global various harsh weather, anti-ly to knock, tension, anticorrosive.Dialing keyboard adopts waterproof sealing metal light touch of key-press, sturdy and durable, being specially adapted to the scene that the noises such as electric power, metallurgy, tunnel, mine, chemical industry, coal, cement, weaving are large, is the desirable radio broadcasting calling talkback system of high noisy, large dust enterprise.
