Abstract
The utility model discloses a one-to-one or one-to-many intercommunication system. The intercommunication system consists of a master control module and receiving modules which are connected through reticles and is mainly used for the field of the conversation among program directors when shooting is carried out at multiple camera positions and the other intercommunication field. When the intercommunication system is used for the conversation among the program directors, if a switcher can provide Tally signals, the master control module can also transmit the Tally signals to the receiving modules through the reticles. The intercommunication system has the characteristics that the power for the receiving modules as well as voice signals and the Tally signals for mutual conversation are transmitted by a same reticle, so that eight cores in the reticle are effectively utilized, and the intercommunication system is convenient and practical.
Description
Technical field
The utility model relates to the mutual phone system of a kind of one-to-many.Specifically main control module and the receiver module that is coupled together by netting twine formed, and can be that a main control module connects 4 receiver modules, also can connect 3 or 2 or 1 receiver module.
Background technology
Existing INCOM intercom main control end mainly is connected with tone frequency channel wire with receiving terminal.Because tone frequency channel wire has only a core or two cores, so just can not be well separately the voice signal of mutual transmission.Also have the required power supply of receiver module also to be not easy to solve, power supply or packed battery in addition go between.If when taking in the multimachine position, cut bank can provide the Tally signal, main control end also is not easy to send the Tally signal to receiving terminal.
Summary of the invention
The problem that the utility model need solve is that the customer service disadvantages of background technology provides a kind of connected mode simple, highly INCOM intercom of Zheng Heing and Tally indication mechanism.
Main control module of the present utility model adopts twisted pair network cable to be connected with receiver module, so just can well utilize 8 cores in the netting twine to come transmission of speech signals, power supply and Tally signal etc. respectively.Convenient and practical.
Concrete technical scheme is, after main control module is plugged the Tally signal of external 5V DC power supply, headset and cut bank input, circuit by self amplifies the mic signal, then the mic voice signal that amplifies is passed to receiver module together with power supply and Tally signal in the lump by netting twine.Receiver module is given the earphone sounding voice signal that receives, and the Tally signal is given LED lumination of light emitting diode, and power supply is supplied with the circuit part of self.Same principle receiver module also has own mic amplifying circuit, and by self circuit with the amplification of mic signal after, pass to main control module by same netting twine, main control module is given the earphone sounding voice signal of receiving again.
Description of drawings
Fig. 1 is the connection diagram of system;
Fig. 2 is each core schematic diagram of 8 core twisted pair network cables.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See Fig. 1, main control module and receiver module all have the RJ45 network socket, with netting twine main control end and receiving terminal are coupled together, and the netting twine crystal head adopts the 568B connection of standard.Main control end is 4 mouthfuls a RJ45 network socket, can connect 4 receiver modules simultaneously, realizes a pair of four conversations mutually.Also can connect one or 2,3 receiver modules, realize one to one or a pair of 2, to 3 intercommunications.
See Fig. 2,8 cores in the netting twine are distinguished with color, be that orange is white respectively, orange, green white, blue, blue white, green, palm fibre is white, brown.
The main control end course of work: after main control module receives external mic signal, circuit through self amplifies earlier, pass to receiver module by blue white and green two cores in the netting twine then, receiver module is given the earphone sounding after receiving signal, thereby the realization main control end is sent words to receiving terminal.
Simultaneously, main control module also provides 5V direct current by the indigo plant in the netting twine, brown two cores to receiver module, and blue core is anodal, and brown core is a negative pole.
When multimachine position instructor in broadcasting takes, when if cut bank can provide the Tally signal, main control module can also be passed to receiver module to the Tally signal of input by orange white, orange, green white three cores in the netting twine, receiver module is given red, green, yellow three LED lumination of light emitting diode the Tally signal that receives respectively again, when cut bank was cut this news road signal, red LED was luminous.When not cutting this news road signal, green LED is luminous.When cutting this news road in advance, yellow led is luminous.Thereby realize the Tally deixis, take personnel like this and just can well hold the shooting behavior of oneself.
The receiving terminal course of work: receiver module receives voice signal that main control end transmits by netting twine, Tally signal, power supply etc., gives respectively that earphone sounding, LED are luminous, self circuit electricity consumption.
Simultaneously, receiver module after self circuit amplifies, is passed to main control module by the white core of the palm fibre in the netting twine with external mic signal, and main control module is given the earphone sounding together with power cathode after receiving signal.Thereby realize that receiving terminal send words to main control end.
The required power supply of the utility model receiver module circuit also is to be carried by the indigo plant of netting twine, brown two cores by main control module.
When main control module connects a receiver module, just can communicate with each other one to one.When connecing four receiver modules, just can a pair of four communicate with each other.When the instructor in broadcasting takes, only need to connect with easy netting twine, just can well finish instructor in broadcasting's INCOM intercom and Tally deixis.
Claims (5)
1. an one-to-many that connects with 8 core netting twines communicates with each other and the Tally indication mechanism, and system comprises main control module and receiver module, it is characterized in that described main control module links to each other by netting twine with receiver module.
2. connected mode according to claim 1 is characterized in that the interface that main control module links to each other with receiver module all is the RJ45 network socket.
3. connected mode according to claim 1, after it is characterized in that the mic signal amplification of main control module with input, pass to receiver module by two cores that are connected in the receiver module 8 core netting twines, in like manner, receiver module is passed to main control module by the other core in the netting twine after also external mic signal being amplified.
4. connected mode according to claim 1 is characterized in that the Tally signal of main control module with input, passes to receiver module by three cores that are connected in the receiver module netting twine.
5. connected mode according to claim 1 is characterized in that main control module with external power supply, by being connected in the two wick feed receiver modules power supply in the receiver module netting twine.
