Description
Technical field
The utility model is related to communication fields, more particularly to a kind of intercom with 4G main control modules.
Background technology
Intercom is called walkie-talkie, as a kind of portable mobile wireless mobile communication product, is used in second of the world earliest
The army of Great War communicates.Global First commercialization wireless interspeaker is released from Motorola in 1948, to states such as Europe, the United States' nineties
Open household intercom market, intercom are widely used in public safety, communications and transportation railway, airport, port in succession for family and area
The various fields such as mouth, building, manufacture, water conservancy, electric power, forestry, tourism, hotel, service.
Existing intercom can only generally realize short haul connection, and the communication distance of intercom is restricted, with most common
For hand-hold wireless intercom, communication distance generally can reach 5 kilometers in accessible opening.In cordless communication network
Support under, by intermediate station communication distance up to 10-20 kilometers.If distance is grown again, can not ensure to communicate.
And the signal transmission distance of intercom has direct relationship with its power, it is right in order to ensure the transmission range of signal
Say that the power of machine is usually larger, general hand-hold wireless intercommunication acc power carries formula wireless interspeaker volume in 4-6w, vehicle (ship, machine)
Larger, power is not less than 10W, generally 25W.Maximum power is that VHF is 56W, UHF 50W.Also individual vehicle-mounted intercommunications are whole
The power in a certain frequency range is held to reach 75W (IC-VX8000).It is easy to interfere other people, equally also be easy by other intercommunications
The interference of machine.Also, this high-power to bring human body radiation very big.In contrast, the power of mobile phone is then much smaller, intercom
Power be usually tens times of mobile phone even hundred times, radiation is also much bigger for mobile phone.
In addition, since existing intercom is limited by distance, if when happening suddenly emergency, dispatch control person is not existing
, then it can not be scheduled using intercom, can only be linked up, discussed with dispatcher by mobile phone by other staff, then
It replaces being scheduled by other staff.The personnel that centre substitutes need to carry out it is two-way report, actual schedule personnel i.e. can not be intuitive
Ground obtains field data, also can not directly give and command, directly affect scheduling quality so that issue handling reconciliation it is never enough and
When.
To solve the problems, such as this, someone's embedded gsm module in intercom is such as announced with realizing the distance communicating of intercom
Number for 102868975 A Chinese patents of CN etc..But with the development of technology, 2G networks cannot be satisfied communication instantly and want
It asks, in particular with the universal of 4G networks.And on the other hand, 4G modules are referred to as the mould containing fourth generation mobile communication technology
Block is the another product under Internet of Things and mobile Internet development.4G modules refer to that hardware is loaded into designated frequency band, software support
The LTE protocol of standard, a kind of highly integrated modular general designation of product of software and hardware.By can be in 4G module applications to intercom
The transmission rate of data is greatly improved, realizes more easily telecommunication intercommunication and cluster communication function etc..But it is existing
4G modules are also relatively high compared to power consumption for 2G modules, and are mainly used for the fields such as Internet of Things, and shortage is exclusively used in intercom
4G modules.
On the other hand, when using 4G modules, the major function that generally 4G modules are used in intercom is to carry out data
Transmission, realize the function of distance communicating.Common practices can use the enterprising enforcement of 4G Module-embedding intercommunication mainboards, and real
Existing above-mentioned function needs the controller in intercommunication mainboard to connect 4G modules, but controller and the processor of 4G modules belong to two
Kind different systems, controller generally control the running of 4G modules by AT instructions, cumbersome in practical application, also cause
Delay and loss.
Therefore, the existing technology needs to be improved and developed.
