Bluetooth (Bluetooth): being a kind of wireless technology standard, it can be achieved that fixed equipment, mobile device and building
Short-range data exchange (using the UHF radio wave of the ISM band of 2.4-2.485GHz) between personal area network.It is developing
Although finding that BLE has many advantages in terms of power consumption and mobile phone interconnection during intelligent gateway, but a disadvantage is that sending power
Very small, generally only 4 ~ 5dbm causes communication distance closer, and only tens meters, effect later through walls is worse.It cannot be complete
Meet the needs of intelligent gateway real work.
Summary of the invention
The purpose of the utility model is to provide a kind of wireless data biographies for power adjustable that suitable intelligent gateway function needs
Defeated device and control method.The device has controllable mode and power output, increases the sensitivity and coverage area of system.
The technical characteristics of the utility model mainly on the basis of BLE scheme, increases PA function.I.e. in the BLE/
Between THREAD dual-mode chip and antenna, RF input-output unit is set, and the RF input-output unit is by radio-frequency receiving-transmitting
PA chip circuit is constituted, to increase transmission power, increases sensitivity.
A kind of wireless data transmission device of power adjustable, including BLE/THREAD dual-mode chip and antenna, feature
It is that RF input-output unit, the RF input and output are set between the BLE/THREAD dual-mode chip and antenna
Unit is made of radio-frequency receiving-transmitting PA circuit, and the PA circuit is arranged the power module individually powered, the power module with
BLE/THREAD dual-mode chip constitutes control loop.
By increasing PA circuit, amplifying output power and improving input sensitivity, reach 1KM effective communication distance；Pass through
Control to PA circuit reaches and is applicable in different mode in different fields；By the control of the feedback to power module, provide not
Same voltage gives PA circuit, to realize different power gains, meets different application；Using negative-feedback algorithm, according to
The wireless signal of transmitting-receiving, can according to need the power supply of automatic adjustment power module, and then reach the mesh for adjusting PA output power
's.The transmission power of the utility model reaches 20dbm or more in this case.
When utility model works, when booting described in BLE/THREAD dual-mode chip power parameter, output setting are set
The supply voltage of PA circuit, the PA circuit communication receiving/transmission data transmission give BLE/THREAD dual-mode chip, the BLE/
THREAD dual-mode chip counts current signal strength and the bit error rate simultaneously, compares to obtain difference with bit error rate setting value, according to PID
Algorithm calculates the adjustment amount of supply voltage, resets power parameter, is output to PA circuit.
The utility model has the advantages that the power sent is adjustable, to adapt to the needs of different working modes.It increases
Transmission range, while sensitivity is also improved largely.It is emphasized that increasing supply voltage can be improved output power, but
It is that power consumption is also increase accordingly, the utility model can reduce power consumption under the premise of guaranteeing laser propagation effect according to effect is transmitted and received.
