Accurate data measurement performance, with its diversified data communication methods, can be applied to a variety of complex installation environment data collection, monitoring.

Kaiyi Internet of Things is a modern agricultural service, let me take a look at this problem.

In recent years, greenhouse planting has brought great convenience to improve people's living standards, and has been rapidly promoted and applied. Environmental factors such as temperature, humidity, illumination, and CO2 concentration in the planting environment have a great impact on crop production. The traditional manual control method is difficult to meet the requirements of scientific and reasonable planting, and the system that can realize the automatic monitoring of the above-mentioned environmental factors in China is not common at present, and the introduction of foreign large-scale multi-functional greenhouse control system is expensive and not suitable for national conditions.

In view of the current trend of greenhouse development, our company has proposed a design of intelligent monitoring system for greenhouses.

System Benefits. fine planting to improve quality;

Bring forward control to reduce costs;

Information management, easy planting;

Digital decision-making, scientific planting;

System features. 1. Remote real-time monitoring of environmental indicators.

Through various sensor devices installed in the greenhouse, environmental and planting information is collected to achieve remote real-time monitoring.

2. Remote control of field equipment.

Commonly used field devices can be controlled through signal lines, and users can complete the sending of instructions such as starting and closing field devices by clicking the buttons on the interface.

3. Automatic control of field equipment.

In addition to the manual remote transmission of instructions, the system is able to automatically control the start-up and shutdown of field devices based on the monitored environmental indicators.

4. Scientific planting management.

The electronic data storage supports data analysis and statistics, assists decision-making, and realizes scientific planting and refined management.

The main role of the greenhouse environmental monitoring system is to monitor the growth of crops in the greenhouse, and to help growers manage the greenhouse more conveniently and quickly through the monitoring of environmental crops in the greenhouse! However, with the continuous upgrading and development of the monitoring system, the greenhouse environmental monitoring system should regret not only the monitoring of the greenhouse environment, but also the control function!

For example, in the past, the temperature and humidity of the greenhouse could be monitored by installing sensors in the greenhouse, and the user could go directly to the growth of crops in the greenhouse through the way of data display! In the present, it is possible to determine which equipment needs to be controlled in the greenhouse through the comparative analysis of the data, such as the control of the fan, the control of the sun visor, etc., and the control of these corresponding equipment can be directly realized through the background to achieve the purpose of adjusting the greenhouse environment.

1. Focus on real-time intelligent monitoring - the comprehensive integrated application of the Internet of Things, sensor network and automation technology, the "health status" of the greenhouse is perceived, and the remote monitoring function responds to the abnormal crop growth environment in the greenhouse in a timely manner.

2. Unified and three-dimensional agricultural data - fully integrate all kinds of agricultural related information (greenhouse monitoring data, agricultural product information, meteorological information, labor information, etc.), so that the information related to farmers' production and life is comprehensive and integrated.

3. Efficient management and control - process technology and real-time monitoring and monitoring technology ensure that farmers can know the growth environment of the greenhouse at home, improve production efficiency and achieve efficient agriculture.

(1) Collection terminal

The measuring points of the environmental monitoring of the 485 greenhouse include air temperature and humidity transmitters, illuminance transmitters, CO2 transmitters, and soil temperature and moisture transmitters. The number of each type of measurement point can be determined according to the actual site needs.

(2) 485 field wiring

It should be noted that the 485 bus can reach 2000m, but the branch line from the bus to each measurement point cannot exceed 1m; The 24V power cable can be routed with the 485, but if the number of measurement points exceeds 25, it is recommended to supply power in sections, and a maximum of 250 485 measurement points can be accommodated in a 485 network.

(3) Small host or GPRS concentrator

Small host: The received monitoring data can be uploaded to the monitoring platform in the form of GPRS data traffic. At the same time, the small host also has an LCD screen, with 140,000 pieces of data storage and SMS alarm function, which can send alarm SMS to the relevant responsible person (up to 5 people), so that the staff can deal with it in time.

A small host can manage 32 485 devices simultaneously.

GPRS concentrator: The received monitoring data can be uploaded to the monitoring platform in the form of GPRS data traffic. One concentrator can manage 8 485 devices simultaneously.

(4) Software platform

All measurement points are uploaded to the cloud server through the wireless network, and the real-time display of data, real-time curve viewing, historical curve viewing, data recording, email alarm, data export, remote web access and other functions can be realized through the cloud environment monitoring platform, so as to realize the 24-hour uninterrupted monitoring of the environmental volume in the greenhouse, and the synchronous data query of the mobile APP.

Power monitoring can test temperature, smoke, humidity and various functions.

It depends on what functions your measurement and control system has, whether the cost performance is reasonable, whether it is convenient for users to use and maintain, how much benefit it will be to reduce the labor intensity of farmers after use, and how much benefit it will be to improve the quantity and quality of output.

The intelligent greenhouse monitoring system is based on the real-time growth environment information of plants obtained by the wireless network, such as soil moisture, soil temperature, air temperature, air humidity, light intensity, plant nutrient content and other parameters through various types of sensors. We did this at the time by TOP Internet of Things, and we had to ask them specifically.
