Lora communication module working at wide voltage

Abstract

A Lora communication module working at wide voltage comprises a Lora radio frequency receiving and transmitting module, the Lora radio frequency receiving and transmitting module is a control center of the whole Lora communication module, has signal control and data processing functions, and is used for sending a control instruction to switch a receiving channel and a transmitting channel of a radio frequency signal of the Lora communication module; the Lora radio frequency transceiver module is connected with a power supply booster circuit, a radio frequency receiving matching network and a radio frequency transmitting matching network. According to the Lora communication module, the working voltage range of the Lora communication module is widened by additionally arranging the power supply booster circuit, the energy of a battery or a capacitor for supplying power can be fully utilized, the utilization efficiency of the battery or the capacitor is improved, the hardware cost of the Lora communication system is reduced by reducing the working voltage of the Lora communication module, and meanwhile, the space of an application product is also saved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a Lora communication module working at a wide voltage. Background technique [0002] Lora (Long Range Radio) is a low-power local area network wireless standard. It is a long-distance radio. Under the same power consumption conditions, it can spread farther than other wireless methods. It realizes the unity of low power consumption and long-distance. Lora The communication protocol signal is transmitted and received through the Lora communication module to realize the construction of the Internet of Things. [0003] For most applications of the Internet of Things, the requirements for the size and cost of the circuit modules of the Internet of Things are relatively high, and it is required to achieve low cost and small size as much as possible. However, most of the existing Lora communication modules use larger power supply modules. Power supply, and the operating voltage ...

[0003] For most applications of the Internet of Things, the requirements for the size and cost of the circuit modules of the Internet of Things are relatively high, and it is required to achieve low cost and small size as much as possible. However, most of the existing Lora communication modules use larger power supply modules. power supply, and the operating voltage range of the existing power supply is relatively narrow, which cannot fully utilize the electric energy capacity of the battery, which also increases the use cost of the entire Lora module
