Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the utility model.
Specific embodiment
It elaborates with reference to the accompanying drawing to the specific embodiment of the utility model wireless receiving module plate.
Referring to attached drawing 1, wireless receiving module plate includes wireless receiving chip 1, power supply unit, antenna element 2 and I/O-unit
3, wireless receiving chip 1, power supply unit, antenna element 2 and I/O-unit 3 are installed on pcb board 4, power supply unit and I/O-unit 2
It is connected to wireless receiving chip 1, wireless receiving chip is SX1278 integrated chip, and the input voltage of power supply unit is DC5-
8V, I/O-unit 3 include several contacts being arranged on pcb board, and antenna element is 50 Europe for receiving signal, antenna impedance
Nurse.
Shielding ring 5 is formed in the periphery of pcb board 2, antenna element 2 passes through shielding ring 5, and the size of pcb board is length
33.5mm width 20mm.Spacing between the contact of I/O-unit is 2mm.
SX1278-P01 wireless module is a long-range witched-capacity network system scheme SX1278 based on SEMTECH
Add the wireless module of level-one power amplification.Other than traditional GFSK modulation technique, novel SX127X platform is additionally used
LoRa (long-range) spread spectrum.
When using this module board, it should be noted that following several points:
1, the traffic rate of module will affect communication distance, and rate is higher, and communication distance can be closer.
2, the traffic rate of module will affect receiving sensitivity, and rate is higher, and receiving sensitivity is lower.
3, the supply voltage of module will affect transmission power, and in operating voltage allowed band, voltage is lower, transmission power
It is lower.
4, the variation of the operating temperature of module, will lead to operating frequency offset, without departing from operating temperature range, not shadow
Response is used.
5, antenna has a significant impact to communication distance, to use and work the nominal antenna of frequency, and standing-wave ratio wants small, impedance
Close to 50 ohm.
6, the installation site of module and mode will affect communication distance.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
Art personnel can also make several improvements and modifications without departing from the principle of this utility model, these improvements and modifications
Also it should be regarded as the protection scope of the utility model.
