Technical Field

[0001] This application relates to the field of intelligent irrigation technology, specifically to a multi-mode irrigation gateway that supports multiple communication methods. Background Technology

[0002] Intelligent irrigation systems utilize the Internet of Things (IoT), big data, artificial intelligence (AI), and automatic control technologies to achieve refined, automated, and intelligent management of the irrigation process. Through soil-embedded moisture sensors and field weather stations, it monitors crop water requirements in real time. Combined with IoT technologies such as 4G / LoRa, the data is aggregated to a cloud platform. Based on this information, the system intelligently determines irrigation timing and volume, and remotely controls valve opening and closing to achieve precise and automated irrigation.

[0003] As the central nervous system of a smart irrigation system, the irrigation gateway is responsible for collecting data from all sensors and uploading it to the cloud platform via a communication network. It also receives instructions from the cloud platform and sends them to the execution devices. However, existing irrigation gateways support relatively limited communication methods, such as 4G / 5G, NB-IoT, LoRa, or Ethernet for interaction with the cloud platform. However, with the increasing communication demands of smart irrigation systems, simply supporting information exchange with the cloud platform is insufficient; more communication methods are needed to enable interaction between different devices or apparatuses.

[0062] The multi-mode irrigation gateway uses a core control module 110, which integrates WiFi and Bluetooth modules, as its core processor. It connects with a LAN communication module 120 and a wireless radio frequency communication module 130 to achieve multi-module collaborative control and data processing. The power supply module 150 supplies power to each module, and the interaction module 140 enables human-machine interaction. It supports WiFi communication, Bluetooth communication, LAN communication, and wireless radio frequency communication. The rich communication methods can meet most of the communication needs of the intelligent irrigation system.

[0063] In some embodiments, the core control module 110 is an ESP32-S3-WROOM-1-N8R2 module. The ESP32-S3-WROOM-1-N8R2 module is selected as the core processor. This module integrates 2.4GHz Wi-Fi (802.11b / g / n) and Bluetooth (Bluetooth5, Bluetoothmesh) functions, and incorporates an ESP32-S3 series chip, a dual-core 32-bit LX7 microprocessor (supporting single-precision floating-point arithmetic units), supporting clock frequencies up to 240MHz. It also features abundant I / O ports and communication interfaces, enabling collaborative control and data processing across multiple modules.

The FSK transceiver module uses the FSK chip RFM2300-REV02, and the OOK receiver chip uses the OOK receiver chip CMT2210LS. The RFM2300-REV02 chip connects to the core control module 110 via CSB, SCK, and SDIO ports to achieve bidirectional data transmission. Its frequency band can be flexibly switched through the combination of resistors R2 and R3 connected to the core control module 110 (433MHz: R2=NC, R3=NC; 917MHz: R2=1K, R3=NC; 315MHz: R2=NC, R3=1K; 868MHz: R2=1K, R3=1K). The CMT2210LS is a high-performance RF receiver chip with an integrated low-IF receiver architecture, effectively reducing the number of required peripheral components and thus lowering application costs. This chip supports a data rate range of 1-5kbps, making it ideal for pairing with low-end transmitters based on encoders or MCUs. The RF chip transmits received data to the core control module 110 via the DATA port. The 27.1383MHz crystal oscillator Y1 provides a precise clock for the wireless communication module. Inductor L5 and capacitor C18 form a special RF matching circuit to improve the receiving sensitivity of the wireless signal.
