Considering that the greenhouse has an area of 200 acres and requires quite a lot of labor in planting and management, it can be considered to be constructed directly into an intelligent greenhouse.

Greenhouse greenhouses, as a necessary building for the planting of anti-seasonal crops, are widely used in the planting of crops with high economic added value. Nowadays, with the application of Internet of Things (IoT) technology, greenhouses in Shouguang and other areas of Shandong have been intelligentized, bird-dogging, and become intelligent greenhouses. Intelligent greenhouse greenhouse because of its lightweight structure, relatively low cost, short construction cycle, a wide range of applications, agricultural planting, seedling breeding, scientific research experiments and other aspects of its figure, used in the construction of modern agricultural parks, characteristics of agricultural towns, leisure and tourism industrial parks.

In order to enhance the design program to the ground executable, usually by the design side and the use of the party **** the same to complete. The designer is generally a professional organization with design qualifications, according to the user's application purposes, construction site environment, local meteorological historical data, construction budget, geological conditions, soil composition, late management and use of personnel and other needs, tailored to local conditions.

Greenhouse design

Design in terms of data on the overall layout, adoption type, span, spacing and opening dimensions should take into account a variety of factors such as structural, mechanical, covering and supporting materials, ventilation, temperature increase, internal and external drainage, as well as the environmental control system, that is, the intelligent greenhouse control system, and so on, combined with the local geographic and climatic conditions, the type of crops planted, and based on the structural frame Design features are summarized:

①, structural layout. Due to the special geographic environment of the country, usually the north and south buildings have better direct sunlight and the highest average total daily transmission rate. It is appropriate to use the main sunny side of the roof, the total amount of light to be greatly increased than using symmetrical northward roof. At the same time for buried structural components needs, should be 0.5 meters below the outdoor ground.

②, covering materials. Glass as a non-crystalline non-metallic materials, high transmittance, used in the construction of greenhouse greenhouse, its transmittance decreases, regular maintenance and cleaning, the use of a long period of time, is the more ideal greenhouse covering materials.

3, ventilation. In order to ventilate and heat exchange with the outside world, should make full use of natural conditions, to determine the direction of the greenhouse window. Based on the wind direction of the local monsoon, choose to leave the skylight in the corresponding direction of the greenhouse, that is, the wind direction of a place for the southeast, the skylight position should be in the north side of the greenhouse.

4, shading system. Due to the special nature of the glass greenhouse, the sun shading system is mostly used in the sunshade net and other equipment, in the top surface needs to be left to install the sunshade net and other equipment interfaces, at the same time, it is best to have a 0.1-meter distance from the top skylight, to facilitate shading at the same time, but also to open the skylight ventilation.

5, temperature control function. The realization of temperature control is different according to the season, summer to cooling as the main demand, can be used in high-pressure spraying and other ways to cool down the problem. Winter to realize the warming of more types of equipment, such as heaters, heating machines, thermal curtains and so on. According to the convenience of the application, need to leave the corresponding installation of the application of the location.

6, irrigation and drainage. As a result of various crops growth stage of the water demand has certain differences, and the possibility of rotating the user to plant a variety of crops, and there is no specific rule to follow. Therefore, the intelligent greenhouse greenhouse irrigation is appropriate to use sprinkler irrigation, you can access the water and fertilizer machine.

Completion of site leveling, independent foundation, ring beams, water retaining walls, water curtains with cisterns and other civil construction. Carry out the next step in the installation work, there is the installation of the main skeleton, system installation, site assembly covering material installation and so on. It is desirable to be installed by a professional installation and construction team, and at the same time need to be on-site and the owner of the communication and exchange of good details.

The greenhouse construction

Three, system installation

This part refers to the mobile seedbed, planting bracket, planting tanks, substrate bags, distribution installation, etc., as well as intelligent greenhouse control system related to the installation of hardware equipment and debugging.

Intelligent greenhouse facilities

Focus on intelligent greenhouse control system installation and commissioning, the main hardware equipment: air temperature and humidity sensors, soil temperature and humidity sensors, soil PH sensors, soil conductivity sensors, carbon dioxide sensors, illuminance sensors, such as collection terminals, intelligent solenoid valves and control terminals and intelligent switchgear and other equipment. Collection of terminal equipment in addition to soil collection equipment, more wall-mounted installation, with screws fixed in the monitoring point can be; soil class collection equipment needs to be inserted into the planting soil; intelligent control cabinet is a manual management of glass greenhouse equipment, it is desirable to be installed in the conspicuous and from the ground with a certain distance from the location. The number of each type of equipment needs to be at least one, according to the size of the glass greenhouse and the number of planting areas divided into, the number increases.

Intelligent greenhouse control system hardware equipment

After the installation is completed, each collection, control, control cabinet and other equipment in turn will be accessed to the management cloud platform, and the corresponding collection terminals will be bound to the control terminals one by one, for example: air temperature and humidity sensors are bound to the skylight system's motors, heating machines, ventilators, and other temperature and control equipment, and the operation logic is set up, i.e., when the sensors are collected, the indoor air will be turned on when it is too high. Indoor air is too high, open the skylight, ventilator, room temperature drops to a certain value when the closure of the skylight and other equipment, if the temperature drops to a certain value then open the heating machine and other warming equipment, specific values according to the growth of planted crops required. Similarly, illumination sensors and artificial fill light, shading system, soil temperature and humidity, soil PH value and other sensors to collect soil data and control water and fertilizer integrated machine intelligent valve.

Equipment installation

About the intelligent greenhouse greenhouse on the cloud platform set the logic management rules, can be modified anytime, anywhere on the cell phone, computer terminal, instant effect. At the same time can be based on the sensor's collection data, intelligent valve battery/voltage/signal and other data, set up automatic alarm, once the alarm conditions are reached, the cloud platform automatically to bind to receive information from the manager, push SMS, WeChat, the cloud platform information, make a phone call and other ways to show the alarm.

Intelligent greenhouse control cloud platform

In general, the construction of the framework of the glass greenhouse is not very difficult, and the construction of the traditional greenhouse is not very different, and the realization of intelligent management of the greenhouse focuses on the application of intelligent greenhouse control system, according to the experience of planting, guiding the management strategy and program of the cloud platform in order to play the greatest efficacy of the modern intelligent greenhouse to achieve the realization of the reduction of manual labor. labor intensity, improve crop yield and quality.
