TNO is working towards remotely monitoring nursery performance . Within the Hortivation Foundation , the first two glasshouse raiser are gaining experience withKas Prestatie Monitoring(Greenhouse Performance Monitoring ) . There are plenty of sensors that render data on the climate or control condition , but sensing element in greenhouse structures are not there yet . Reason for TNO to investigate , on its own enterprise , whether this is potential .
TNO already has a portion of experience with this proficiency . For several years now , well - known steel bridges like the Van Brienenoord Bridge have been equipped with sensors . These readings are linked to a computer mannikin of the bridge . This allow blemish to be discover at an early stage . The bridgework ’s residuary life and guard can also be determined at any time .
" Using sensors in the alloy profile of a nursery , we want to see if we can gain more insight into what , for example , a hailstorm , stiff wind , earthquake , rain , sun , insensate or hotness do to a glasshouse structure , " says Egon Janssen , the greenhouse engineer at TNO . " Or monitor how often a greenhouse deck cleaner goes over the deck of cards with what weight unit and what this does to the greenhouse ( sewer ) . "
alternate to lab testFor some forty years , TNO has been deal enquiry on greenhouse profiles in laboratories . This involves subjecting them to a stock psychometric test cycle that applies all storms and snow rain shower to the greenhouse structure during the design living of 15 years , over the trend of a few day .
" Because every construction site has different weather condition , we do n’t know from the be nursery what residuary aliveness they have . On top of that , many nursery in the Netherlands are older than the original design life of typically 15 days . "
For this reason , TNO need to build knowledge on the effect of practical loads from wind , C. P. Snow , crop , deck washers , and even earthquake on the residual biography of the structure . Sensors in multiple nursery components such as rod cell , sewer , trellises and pillar , recall several dozen per hectare , provide coverage across the entire anatomical structure and data point insight .
In a pilot project , some parties are now starting to exploit with sensors in the greenhouse mental synthesis . " The interrogative now is whether we get enough and the correct insights from the sensor datum after one storm , one snow and one greenhouse cover cleaning . detector are still very expensive now , so sensors in every glasshouse structure is a pipe dreaming for now . " For now , at least . " Globally , unexampled developments on the program of AI , sensing element and monitoring are going very tight . "
