LORA data transmission base station is used to aggregate on-site wireless sensor data and then send the current data to wireless transmission devices through LORA wireless channels. 

GPRS data transmission base station is used to receive and aggregate information from surrounding sensors, and then forward wireless data information to the backend host or other terminals through GPRS. The data transmission base station consists of MCU, communication interface, 2.4GHz digital RF transceiver, communication module, wide input DC/DC stabilized power supply, IP67 housing, and RF antenna. The dual channel wireless link forms spatial diversity, improving the reliability and environmental adaptability of data transmission.

The wireless data transmission base station consists of MCU, digital RF transceiver, wide input DC/DC stabilized power supply, IP65 spray painted cast aluminum shell, and high gain antenna. Multi channel wireless links form spatial diversity, improving the reliability and environmental adaptability of data transmission. The data transmission base station receives and aggregates information from surrounding sensors through LoRa communication. Then, the wireless data information is forwarded to the backend host or other terminals through Ethernet/4G (supporting custom protocols), and the base station also supports local and remote program upgrades.

Wireless gateway is used to receive, aggregate, and forward sensor node information, and all data is transmitted through wireless channels. Composed of a microprocessor, AC-DC power module, 2.4G wireless module, LoRa wireless module, real-time clock circuit, voltage monitor, etc., it has self-organizing network capability. When there are other wireless gateways within the signal coverage range, a star shaped wireless network is automatically established through topology control mechanism and network protocol, increasing the signal coverage range and wireless network redundancy, and improving the reliability of the system. The wireless network established by the wireless gateway is a star topology structure, with each network consisting of one wireless gateway (central node) as the host and one or more wireless gateways (stations) as the slaves. The host aggregates all sensor node information from the slave and forwards it to the data transmission base station through a 2.4G network to the backend system.
