Monitoring system and monitoring method for agricultural multifunctional Internet-of-things

Abstract

An embodiment of the invention provides a monitoring system and a monitoring method for agricultural multifunctional Internet-of-things. Through combining an industrial-grade multiple-programmed PLC with an industrial-grade network communication box, an industrial-grade cabinet can resist a plurality of kinds of natural factors in a field environment. Cooperation of a wired manner and a wireless manner is utilized on a transmission signal, thereby maximally ensuring data transmission stability and remote control reliability. The industrial-grade multiple-programmed PLC is synchronized with a platform through the industrial-grade network communication box, and the program of the PLC can be remotely modified through the platform, thereby realizing high flexibility of the system. One network communication box can be connected with a plurality of PLCs, so that data are synthesized to one platform through one network communication box. Different species of the agricultural Internet-of-things can be realized through one multifunctional system, and a plurality of control requirements of an agricultural enterprise are satisfied.

Description

technical field [0001] The present invention relates to the field of agricultural internet of things, in particular to an agricultural multifunctional internet of things monitoring system and monitoring method. Background technique [0002] The Internet of Things (Internet of Things, referred to as: IoT) is literally the Internet of things connected. Its purpose is to connect ubiquitous terminal devices, including sensors, controllers, smartphone terminals, home smart devices, etc., to achieve real-time information exchange and communication. The Internet of Things is generally considered to be an emerging hotspot in the development of next-generation information technology. [0003] Agricultural Internet of Things is an important field of Internet of Things applications. It comprehensively uses Internet of Things and various communication technologies to connect sensors such as temperature, humidity, pH value, illuminance, and soil nutrients in agricultural production site...

AI Technical Summary

Problems solved by technology

[0009] First, the current Internet of Things monitoring system generally adopts the mode of "reporting data-remote server computing-issuing control instructions". The central server acts as a "commander" or "smart brain". Just the "clairvoyance" and "robot hand" of the remote server

Due to the many layers of the network from the sensor to the central server, there may be conversions between various communication protocols such as Zigbee, Bluetooth, Wifi, GPRS, CDMA, 3G, 4G, etc. The high packet loss rate and large delay of the network cause the communication chain Failure of any part of the road will cause the "intelligent brain" to be unable to see or hear, have no events to process, and cannot execute the instructions issued

In this way, no matter how intelligent the "controlling brain" is, it will be paralyzed and unavailable

[0010] Second, the complexity of the field environment of agricultural enterprises makes its control requirements more complicated, and the current monitoring system of the Internet of Things is difficult to meet the needs of flexible configuration

The environment required by animals is different from the environment required by plants. Assuming that there are two species of animals and plants in agricultural enterprises, then agricultural enterprises need to use two systems to control, which brings inconvenience to the control system of agricultural enterprises
