suppose : an employee who is scouting , walking through a brilliant purple nursery . But everywhere he goes , the light turn white so that he can look around easy . Once he leave , the lights return to the optimum spectrum for plant maturation . Chess Wise , which germinate wireless inflammation control systems , is work on a proficiency that stimulate this potential . It is a technique that already exist in office buildings and which the Haarlem - based company is currently apply to greenhouse gardening . The company did this for the first time some four years ago . At the prison term , it was used to wirelessly control inflammation habitue in greenhouses .
" With the initiation of LED grow lights , we cease up in gardening , " says Sales Manager Wim Hogenhout one afternoon in March at the office in Haarlem . Just before that , he explained in detail the technology that the troupe was working on and secernate us about the line of descent of the company . For this , we have to go back to 1988 when Chess , a Dutch abbreviation for Computer Hardware en ( and ) System Software , was ground . now , that company has separate into several branches , with Chess Wise participating in wireless command systems , such as light . The technology for this , based on a internet internet ( a secure variant of the well - known WiFi internet ) , was already in use in the actual demesne sector . The kindling in offices , including at Chess Wise itself in Haarlem , is ascertain wirelessly with it .
Endlessly scalableAs soon as we maltreat out of Wim ’s office , the light go out . The Mymesh scheme is creditworthy for this . A movement sensor helps . Wim : " The system is instigate by nature , in which a flock of birds or a school day of fish go forward in enormous numbers without colliding , but notably without one clear loss leader . Everyone communicate with each other . It ’s really the same with a lighting system controlled by Mymesh . The system is not subordinate on one central decimal point , as is the case with WiFi . Mymesh has no undivided - point of nonstarter . This makes the system incessantly scalable . "

The endless scalability is one of the reward Wim likes to target out when explain the engineering . " In nursery gardening , you often see fixtures that are install with cables in a checker board pattern . raiser can tack the lamps on and off in large blocks , but they are not pliable and are dependent on the cabling . Moreover , when switch in a checkerboard pattern , they quickly lose the homogeneousness of the inflammation in their glasshouse . Without cables , with the correct software and with the utilisation of dimmable mending , they have the opportunity to control much more specifically . "
Wireless pin devicesChess Wise develops two types of mental faculty for this use . One module per fixture controls the driver , the power provision , on the dimmable lamp . The other module , the setpoint control module , linked to a mood computer , passes on ' messages ' to the entire web , with each module go by on that message . Only one of these setpoint control faculty is postulate , or several in the fount of very big projects . " But compared to all those measure of cable , our web is chinchy . "
In addition to being scalable , the wireless control system is also secure , Wim bespeak out . " As Chess , we have a background in wireless payments with PIN gimmick , among other thing . We develop the technology behind the first wireless roving defrayal terminals . We also use the nonindulgent requirements to make this dependable in horticulture . Moreover , each module that we produce here in the Netherlands has unique encoding and assay-mark . This means that it is not potential , as is you’re able to with remote controls for goggle box , to control several of the same types of TVs with just one remote control .
dim by colorThe wireless mesh usually works with a waiter in the swarm . This makes it possible for agriculturalist to operate the internet remotely and for Chess Wise to offer outback reenforcement and implement the latest development . The only thing want for this connexion is a ' gateway ' . Most growers take to go without the cloud connexion , with an only local working internet linked to the mood information processing system , Wim says . " The gateway is present and is used by Chess for remote support and control at the agriculturist ’s request . "
A new evolution being work on is dim brightness level very specifically by semblance , as in the exemplar already break in the introduction . This requires the employee to wear a tag end that communicates with the lights . As mentioned , the technology is already available in a similar form in the veridical estate sphere for track&trace practical app . first appearance in the horticultural industry is still some way off .
vulnerability with Mymesh at Vitarom in Germany
Controlling four ability supplies simultaneouslyAnother ontogeny , a module that can check four exponent supplies simultaneously instead of one , is already on the market . Currently , one power supply per color with one mental faculty is still demand for this . For a project at the German tomato grower Vitarom in Grevenbroich , this Cartesian product , with four - channel functionality , will already be on the marketplace this summer . Wim : " With this , the grower will be capable to ensure the vividness even more specifically . " This is an file name extension of a project at the cultivator ’s premises . At the bit , 16 hectares of Tungsram have 3,200 dimmable fixtures with a Mymesh Micro BLC Industrial wireless controller from Chess Wise . The fixity are divided into seven chemical group , each of which can be control individually with one mouse detent .
The Chess Wise module can be seen on top of the luminaire .
duplicate productionChess Wise was introduced to glasshouse horticulture via the fixtures of fixture producer MechaTronix but is sovereign of any make or fixture . Wim currently regard lighting companies in the securities industry that have their own wireless control organisation , companies that work with wired control , and companies that are looking for a dominance solution . " We have a result for the latter mathematical group of companies — a proven technology from the human beings of genuine estate , which is in particular interesting collapse the current energy developments . Besides let a crop to grow optimally with natural and artificial lighting , vim - saving is now more and more important . If you may then dim your luminance in a targeted way , that is a major vantage . Moreover , as we have find out in practice , agriculturalist can sometimes even double their production by using right inflammation . "
In greenhouse gardening , the developer of wireless ascendance system restrain himself to produce the module and commissioning the systems at the grower . sensing element technology is not supply for greenhouse gardening app . " The installer accept concern of installing the fittings , the power supply , and our faculty . We call in projects to put the system into operation . For this , we consult with the agriculturalist on how the groups should be arranged . " Therefore , a visit to Vitarom ’s greenhouse is on the agenda again for later this year .
