Description

The control method of low-power consumption distance transmission system
Technical field
The present invention relates to communication technical field, more particularly to a kind of control method of low-power consumption distance transmission system.
Background technology
Bluetooth (Bluetooth) technology, it is a kind of holding equipment short haul connection (in general 10m) radiotechnics, Using Bluetooth technology, it can effectively simplify the mobile communication terminals such as palm PC, notebook computer and mobile phone handsets and set Communication between standby, also can successfully simplify the communication between the above equipment and internet Internet, so that this The data transfer between modern communications equipment and internet becomes more rapid efficient a bit, is radio communication widening road.Bluetooth Technology causes modern some mobile communication equipments and computer equipment for carrying easily, it is not necessary to can just be networked by cable, and energy Wireless networking is enough realized, its practical ranges can also be extended to the letter such as various household appliances, consumption electronic product and automobile Household electrical appliances are ceased, form a huge cordless communication network.Bluetooth technology belongs to a kind of short distance, the wireless connection skill of low cost Art, is a kind of open scheme that can be realized voice-and-data and be wirelessly transferred, and its message transmission rate is 1Mbps.
But there is also limitation for Bluetooth technology:Transmission range is short.The transmission range length of bluetooth and the hair of bluetooth equipment Penetrating power has direct relation, and the maximum transmission power of bluetooth equipment can be divided into 3 grades:100mw(20dB/m)、2.5mw(4dB/m)、 lmw(0dB/m).When bluetooth equipment power is lmw, its transmission range is generally 0.1~10m.When emission source is close or remote From and when changing the received-signal strength that bluetooth equipment receives, bluetooth equipment can automatically adjust transmission power.Work as transmission power When bringing up to 10mw, its transmission range can be expanded to 100m, if brought up to transmission power most using power amplifier amplifying circuit During big 100mw, its transmission range maximum also can only achieve 150m in the case of unobstructed.By the transmitting for improving bluetooth equipment Power increases transmission range, many deficiencies be present:1st, transmission range can not still meet industrial requirement;2nd, signal circuit is being put When big, while noise signal is exaggerated, the reliability of data transfer can be reduced;3rd, Bluetooth signal transmission frequency is 2.4G, is belonged to High-frequency signal, easily disturbed by external causes such as weather, buildings;4th, the design improves Bluetooth transmission power, necessarily brings High power, height radiation.The above has limited to the development of bluetooth, and family, small area communication biography can only be turned into by being doomed bluetooth Transmission scheme, modern industry requirement can not be met, remote, overlength distance communication terminal is controlled, communicated.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes the controlling party of low-power consumption distance transmission system Method.
The control method of low-power consumption distance transmission system proposed by the present invention, comprises the following steps:
(A) data of module X Bluetooth chip output are remotely sent by processing by RF radio frequency chips;
(B) module Y RF radio frequency chips carry out processing output to mould after receiving module X RF radio frequency chip output informations In block Y Bluetooth chip;
(C) when mobile terminal x, y of only Bluetooth chip can carry out remote data transmission as follows:
(A1) mobile terminal x data are transmitted into module X Bluetooth chip by Bluetooth chip;
(B1) step A is performed;
(C1) step B is performed;
(D1) data of mobile terminal y blue tooth interface receiving module Y Bluetooth chip output;
(D) when module has unique identity ID codes, module X, Z can carry out data transmission as follows:
(A2) step A is performed;
(B2) module Y RF radio frequency chips are sent again after receiving module X RF radio frequency chip output informations;
(C2) module Z RF radio frequency chips carry out processing output extremely after receiving module Y RF radio frequency chip output informations In module Z Bluetooth chip;
Identity ID codes containing module Z in the data transmitted in described step A2, B2, C2.
Preferably, described Bluetooth chip is CC2540, and RF radio frequency chips are SX1278.
Preferably, microcontroller and RF radio frequency chips are integrated in module X, module Y, module Z, module X, module Y, mould Block Z is carried and is extended out antennal interface and onboard antenna.
Compared with prior art, there is following technique effect in the present invention:The coverage of transmitting of bluetooth is set to expand from 100m Greatly to 3km;RF radiofrequency signals carry out package by International Standard, and software configuration and code have all by redefining There is very high security;RF signals penetrability is good, strong antijamming capability, further enhancing the transfer reliability of blue-teeth data.
