Greenhouse cultivation management has its tricks - learn them and you can rely on them

On May 10, 2018, the China International Flower and Horticulture Exhibition grandly opened in Beijing. Past flower shows have always been great opportunities for industry information exchange and product display, and this year's flower show is no exception, with numerous cutting-edge technology and equipment making their appearance at the flower expo. Among these technology and equipment, a compact and flexible figure caught the reporter's eye - Priva Compass. It is reported that this product will also be displayed at the GreenTech exhibition in the Netherlands.

Priva Compass is a brand-new automated control system that can precisely control the crop production environment. It can take the wheel of greenhouse irrigation, climate, lighting and energy elements. Mr. Bram Koppert, General Manager of Priva Group Asia, stated that whether it is a plastic multi-span greenhouse grower in Mexico, a simple and efficient solar greenhouse contractor in China, or an owner of a high-tech fully enclosed glass greenhouse in the Netherlands, the products Priva provides are all of high quality, but the best solutions will be provided according to the needs of different growers.

Priva Compass can be applied to different users

Two versions, switch freely

Compass has two basic versions: 2S and 4S. At the exhibition, the reporter learned that growers can choose the version they need based on the number of measurement and control objects. Compass uses the Priva Blue ID C4 controller, which means users can expand it with various modules, and the installation and commissioning of modules and controllers are very simple. You can add as you use, which increases the flexibility of operation. Hearing this, many people with choice phobia, like the reporter, may feel a bit confused. How exactly should you choose? In fact, choosing the right Priva Compass model only takes three steps: choose the theme: irrigation, climate, photosynthesis, water or energy; choose the level: basic or advanced; choose the I/O modules required for the device. After that, you can match a perfect solution.

Compass installation process

Multiple functional modules, choose by yourself

Compass includes multiple compact and flexible hardware and software modules with simple operation, allowing users to monitor the process at any time. Compass's software modules include control of irrigation, climate, photosynthesis, inter-irrigation and energy. For small projects, it is fully functional and flexible. By modularizing functions, users only need to purchase the software modules they need, which is economical and affordable!So here comes the question,Compasswhat modules are available for selection?

Customizable functional modules

Climate module

Environmental conditions are very important for plant growth. Using the climate module, temperature, air humidity and airflow can be easily controlled and optimized. With it, disease risk can be reduced to a minimum, and crops can grow better. Usingbasic climate module, users can perform climate control for a single crop zone within a climate area. This module can be used to control two groups of vents, two-stage cooling, two-stage heating, and one layer of screen based on two time periods per day in the greenhouse, with a single temperature and humidity measurement. Andadvanced climate modulecan fully control the entire crop area. Based on four time periods per day, each crop zone can be equipped with four temperature and humidity measurement boxes, and can control four groups of roof windows, cooling stages, four groups of fan heaters, and two layers of screens. It can also connect four temperature sensors, four plant temperature sensors and an independent heating system.The advanced climate module fully takes external climate parameters into account and has user-defined programs, greatly improving flexibility。

Irrigation module

Water is essential for any crop. By using Compass's irrigation module, growers can optimally control the supply of water and fertilizer to plants at the exact time to achieve the best combination required by the crop. Among them,basic irrigation modulecan use one start strategy to control up to ten irrigation valves. Irrigation can be started manually or automatically according to a weekly schedule, irrigation time, average radiation or total radiation. Andadvanced irrigation modulecan support up to forty irrigation valves and ten start strategies, and can also control one drainage sensor and up to ten moisture sensors to optimize start strategies, and can connect up to forty drainage valves.

Photosynthesis module

Photosynthesis is the starting point of all plant growth. Using the Compass photosynthesis module, growers can control and optimize light and carbon dioxide to achieve the optimal balance in the photosynthesis process, so that crop quality is better and yield is higher.Basic photosynthesis modulecan control a single growth lighting circuit within one system.Advanced photosynthesis modulemanages up to four lighting circuits. At the same time, according to high or low radiation levels, carbon dioxide enrichment can be automatically controlled.

Water module

When crops need irrigation, the water system supplies water. Through the Compass water module, growers can provide accurate water and fertilizer to crops.Basic water modulecan control one water pump and one flow sensor.Advanced water modulenot only controls pump operation and flow measurement, but also supports up to five fertilizer channels. Based on flow, EC or pH, you can adjust EC, acid, alkali or other liquids, and can use up to 8 irrigation recipes.Enterprise-level water moduleis based on all the functions of the advanced water module, plus an expansion of three fertilizer channels, and can control up to eight fertilizer channels at one time. Most importantly, this module supports EC pre-control and can manage up to eight water tanks and one backwash filtration device.

Energy module

To achieve optimal climate conditions, energy use is essential. Through the Compass energy module, growers can control the boiler in the most efficient way.Basic energy modulecan control up to two boiler pumps.Advanced energy modulecan not only control pumps, but also control the entire boiler. This module can handle up to four boilers and one mixing valve. In addition, the advanced energy module provides user-defined control programs, allowing growers to combine energy system control with other devices.

"Liberating" growers

As we all know, desktop computers are no longer our only commonly used computing devices. With the Compass system, greenhouse growers can also become free "phubbers", elegantly and calmly controlling your Priva Compass conveniently from a PC, tablet or smartphone at any time. Moreover, Priva Group has designed a simple and clear Chinese operation interface for the Chinese market, and is equipped with intuitive dashboards and clear graphical interfaces, allowing Chinese users to intuitively understand the environmental conditions in the greenhouse and more easily control greenhouse water and fertilizer, climate and energy.
