Briefly describe the functions of domestic lora modules

Release time: 2022-07-15

The domestic lora module is an ultra-long-distance wireless transmission scheme based on backbone spread spectrum technology. At present, there are free frequency bands such as 433, 868, and 915MHz in the world. Lora module communication technology is characterized by high sensitivity, long transmission distance, low power consumption, and many networking nodes. Mainly used in the Internet of Things industry, such as wireless meter reading (electricity meter/water meter), industrial automatic control, environmental monitoring, environmental monitoring, etc.

The function of the domestic lora module:

First of all, the transmission distance is the same as ordinary modules, using lora spread spectrum technology, the transmission distance is 3~8km, but the transmission method has unique characteristics. The module can choose three communication modes, divided into low power priority mode, balanced mode and multi-off priority mode. That is to say, if low power consumption is required, a mode can be used if the transmission distance is not far, so that the power consumption will be very low. The same goes for other models.

Then there is a gateway feature of the domestic lora module, which can be networked through the gprs3G4G network and NB-IOT (Internet of Things). Some people may ask, why not directly use GPRS or 4G to transmit data? Because there is no signal everywhere, and the signal is also very good, this function is mainly for those places where there is no signal or the signal is not good. But the data needs to be transmitted to online servers, such as some oil wells, remote mountainous areas, gas stations, etc. This unique lora gateway can be used for data transfer,

The purpose is to realize the data communication between device-to-device (different kinds of devices can also communicate) and the device department platform, without requiring users to establish a data center and care about protocols.

The second is the TCP/IP external protocol stack and the script programming function. Anyone who knows something about the communication industry should know that the transmission speed is much faster than the built-in protocol stack on the market, and the stability of data transmission is 25% higher than that of peers and other countries.

Let's talk about the script programming function first, which is also one of the features. Using this function can achieve many things that users want to achieve. (1) Actively collect serial port data, users do not need to add a separate controller. This domestic lora module can actively collect the data of the electrical port, and then package it and send it to the server. (2) Switch control, (3) Simultaneous acquisition of multiple devices, (5) Data filtering.

The center can also take the initiative to issue instructions to let the domestic lora module temporarily collect data and report it immediately. That is to say, the module is two-way communication and supports issuing commands.

Finally, the networking methods are diversified, with the characteristics of point-to-point, point-to-many, and many-to-many, etc., support traditional star networking and unique mesh network, and can meet different application scenarios.

A mesh network is a mesh network with a complex structure. Any device in the network can communicate with each other. In the same network, it has communication functions such as broadcast, on-demand, and multicast. It also supports adaptive relay functionality for any device. It can build a communication network to meet the needs of users in any complex environment.
