Forecast and measurement other information
The weather forecast describes an expected condition and the local sensor gives the specified time and point of measurement. The two cannot be replaced in the Greenhouse control. The investor first clarifies what decision he intends to use the weather. It may have a role in preparing the planned operation, while the current situation remains shown by local measurement. M Hoogendoorn algorithms and WUR The location-dependent design approach gives a professional background to the connection of data sources. However, the operating conditions and limitations of the own system should be understood separately in the discussion.
What kind of intervention can be prepared?
The use of forecasting data can be interpreted if the associated process is specified. The control does not usually respond to the weather, but controls specific equipment and condition. Find out from the operating description which decision supports the expected data and which intervention requires current feedback. The supplier of the system shall demonstrate the connection in some typical situations. This way the customer can see which function is designed to help and which direct control element. The relationship of the expected state with the current measurement shall not remain blurred programming function, which is interpreted only on the basis of the graph shown on the screen.
A different output may also be operated
The uncertainty of the forecast shall be addressed in the system concept. The actual local weather may deviate from the previously expected weather, so let it be clear how control follows the current state. The investor should ask him about the reaction to obsolete, missing or contradictory data. The date and source of the data shall be recognised for the operator. The relationship between the programme and manual intervention shall also be identified. The aim is not to leave the forecast, but to avoid the expected event being treated as a proven future measurement. The role of local control and evaluation remains in operation.
The data version is also kept for evaluation
In a post-operative study, the weather data later downloaded is not always sufficient. The forecast available for the decision then and the actual measurement provide different information. If the system has prepared an operation on the basis of such data, the interpretation shall also follow the date and version of the operation. In the log, the status, operator modification and feedback can help you understand the event. The customer therefore clarifies in advance what data is stored and how it is available. The later fine-tuning can thus be based on its own operational experience, not merely the situation described from memory.
The operator shall understand the connection
In training, it is worth showing the different roles of expected and current status on a simple example of cultivation. The operator shall recognise when the forecast has been modified and which system function it is connected to. Instead of the rated algorithm function, the decision path of the own establishment shall be explained. The ability and history of changing the settings should also be orderly. The forecasting solution can thus be used to support the cultivation strategy. It does not produce a certain result in itself or automatic handling of all exceptional situations; the specific capability is given together by equipment, data and local operating order.
Questions to reconcile the project
- Which decision is supported by the forecast, and which one needs current local measurement?
- What happens in the absence or other forecasts than actual weather?
- Does the data version used at the time of the decision and the history of the operation carried out remain?
Professional background
The related international system solutions are provided by these primary manufacturers and execution sites. The decision aspects of the project shall be interpreted independently by the article; the specific size and content of the undertaking shall be clarified on the basis of the investment data.
