Protocol converter and control method

Abstract

The invention discloses a protocol converter. The protocol converter comprises an uplink communication interface module, a control unit, a processing unit and a downlink communication interface module, which are connected in sequence, wherein the control unit is further connected to a first LoRa driving module; the first LoRa driving module is further connected to a first antenna device; the control unit is further connected to a second LoRa driving module; and the second LoRa driving module is further connected to a second antenna device. A LoRa technology is applied to the protocol converter, when a received or sent signal transmission distance is long or the requirement for signal loss control is high, external communication can be carried out through a LoRa wireless technology, so thatthe original functions of the protocol converter are not affected while the low-power and long-distance transmission of a signal are achieved, the energy is saved, the environment is protected, and the structure of the protocol converter is not too complex.

Description

technical field [0001] The invention relates to the communication field, in particular to a protocol converter and a control method. Background technique [0002] LoRa is one of the LPWAN communication technologies. It is an ultra-long-distance wireless transmission scheme based on spread spectrum technology adopted and promoted by Semtech in the United States. This scheme has changed the previous compromise between transmission distance and power consumption. It can provide users with a simple system that can realize long-distance transmission, low power consumption, long battery life, and large capacity, and then expand the sensor network. [0003] The protocol converter is used to realize the conversion between different protocol interfaces. For the external communication methods of the existing protocol converter (such as GPRS, CDMA or bus, etc.), as the transmission distance increases, the signal attenuation will become more and more Seriously, this requires the protoc...

[0003] The protocol converter is used to realize the conversion between different protocol interfaces. For the external communication methods of the existing protocol converter (such as GPRS, CDMA or bus, etc.), as the transmission distance increases, the signal attenuation will become more and more Seriously, this requires the protocol converter to amplify and relay the received signal. However, when the received signal is severely attenuated or the signal to be sent will be severely attenuated, the requirements for the amplification factor and amplification accuracy of the protocol converter are very high, which will lead to a more complex structure of the protocol converter, which is not conducive to energy saving and environmental protection, but also increases manufacturing costs
