The 6th China (Beijing) International Irrigation Technology Expo and China (Beijing) International Smart Agriculture Equipment and Technology Expo were grandly opened at the Beijing Exhibition Center from March 26 to 28, 2018. As the largest irrigation exhibition in China, this exhibition was jointly initiated and organized by organizations such as the Australian Irrigation Association, the European Irrigation Association, the Chinese Academy of Agricultural Sciences, and the Beijing Rural Work Committee, involving 33 countries and regions and more than 35000 professional visitors.

Beijing Tianzheng High tech Intelligent Technology Co., Ltd., as an exhibitor, was also lucky to participate in the "Closed door Forum on Focusing on Silk Road Cooperation and Joining Hands with Reclamation Area for Win win". At the conference, the general manager of the company took the high-tech and agricultural Internet of Things as the foothold, and the future development of smart agriculture in China and the "the Belt and Road" countries as the direction, shared the prospect analysis of the industry, the company's technical support and the future development direction of the enterprise.

After the meeting, Mr. Gao Fei, the Commercial Ambassador of the Embassy of Israel in China, visited the Tianzheng High tech booth in Beijing and learned in detail about the "Tianzheng High tech Intelligent Irrigation System". He expressed his affirmation and appreciation for the company's products and discussed with the company's General Manager about the future plans to introduce this intelligent irrigation system into Israel.

The Tianzheng High tech Intelligent Irrigation System consists of three parts: information perception layer, information transmission layer, and information application layer.

Information perception layer: Composed of various sensors, through advanced sensor technology, multiple parameters that support fine process management can be wirelessly obtained through the Internet of Things, such as soil temperature, humidity, salinity, and environmental information of crops (air temperature, humidity, wind speed, wind direction, atmospheric pressure, rainfall). At the same time, the system can be connected to devices such as water level gauges, ultrasonic remote water meters, and intelligent dome cameras, allowing users to not only perceive irrigation needs, but also have a comprehensive understanding of the irrigation process.

Information transmission layer:The various data obtained by sensors will be wirelessly transmitted to the intelligent gateway through the LoRa IoT protocol. The gateway will upload the data wirelessly to the cloud center, and the issuance of irrigation instructions will also be implemented through the gateway. All communication between device groups will be achieved through wireless transmission.

Information application layer:At the information application layer, users only need to view all data information through mobile apps or computer clients, and can also issue irrigation control commands, thereby achieving remote, wireless, precise, and scientific irrigation.

The Tianzheng High tech Intelligent Irrigation System has the following characteristics:
The IoT operating system and transmission protocol with independent intellectual property rights, as well as the independent communication protocol with 8-segment frequency modulation technology, effectively solve the problem of signal anti-interference.
1、Intelligent gateway and wireless sensor nodes with free patented technology and appearance design. The intelligent gateway can automatically switch on and off at regular intervals, and can also be linked with sensor settings.
2、Using Lora technology, low-power long-distance transmission, with a battery life of up to 10 years and a transmission distance of up to 15KM.
3、Wireless sensor nodes have self-organizing network and self communication functions. Support stable wireless transmission in complex terrains and underground spaces.
4、The system adopts a unique approach to achieve self discovery and self diagnosis of fault sensing nodes.
5、Graphic big data analysis report output, supporting real-time viewing and control on both mobile and desktop devices.
6、Adopting a secure architecture design to ensure the security of the system.
7、Support the combination of cloud storage and local storage.
8、The system has the functions of cloud computing and fog computing, and solves the problems of cloud transmission delay or unexpected cloud failures by improving local intelligent processing capabilities.
