1、 Background Overview

At present, most crops in our country are planted in greenhouses, while vegetable cultivation in greenhouses has strict requirements on temperature, humidity, light, ventilation, irrigation, etc. in greenhouses. In the past, planting workers operated by experience. This method is not only inefficient, but also inaccurate.

All data of greenhouse environmental indicators are collected by sensors and uploaded to the data storage platform. First, we can fully understand the environmental conditions of each greenhouse; Second, the development of seedlings can be viewed through high-definition video; Third, automatic management of ventilation, lighting and irrigation can be realized through threshold setting.

As a smart Internet of Things terminal solution service provider integrating R&D and intelligent manufacturing, Mantu Technology has launched the "greenhouse networking and intelligent control system" using MTIC 3.0 cloud platform, wireless data acquisition terminals and edge computing technology. The system is helpful to complete the real-time collection, monitoring, analysis and early warning of the greenhouse environment through technical means, intervene and control the internal designated equipment, and make full use of modern Internet of Things technology to ensure the suitability and stability of the greenhouse environment.

3、 Scheme features

※ High real-time: collect the data of each monitoring point in real time and transmit it to the MTIC 3.0 cloud platform for data analysis and dynamic display through big data billboards.

※ High security and high reliability: the system can effectively prevent illegal access, illegal access, virus infection, hacker attacks and other network attacks, with high security and confidentiality; The system adopts mature, stable and universal technologies and equipment, which can ensure the long-term stable operation of the system, and has strong fault tolerance and system recovery capabilities.

※ Early warning and intelligent analysis: the data collected in real time can be compared with the set threshold value to give early warning and leave enough time for relevant personnel to dispose; The MTIC 3.0 cloud platform can analyze what time period and where alarms are likely to occur through intelligent analysis algorithms, so as to stabilize the growth environment in the shed from the root.

※ Strong remote control capability: remote intervention control, parameter adjustment, switch and other control operations can be performed on remote control equipment through MT-BOX.

5、 Introduction to MT-BOX Intelligent Terminal

MT-SR411 is an intelligent terminal with the functions of remote centralized acquisition and control. It provides the capabilities of 1-channel RS 232 interface, 1-channel RS 485 interface, 8-channel switching value acquisition, 8-channel relay output and 4-channel analog quantity acquisition. MT-SR411 can directly access analog signals, level signals, dry contacts, etc. output by various sensors, standard transmitters, meters, etc. It is an excellent choice for remote wireless acquisition and measurement and control.

MT-SR411 Intelligent Terminal

The MT-SR411 can report the field sensor data to the MTIC 3.0 cloud platform in real time, thus completing a series of subsequent operations such as early warning and intelligent analysis; At the same time, the MT-SR4100 intelligent terminal can also control the automatic watering device, roller shutter control device and other equipment through the reverse control capability.
