___., 10 45 20 25 35 l 453 539 N* Känd teknik Skötsel och rengöring av sândar- och mottagarfönster enligt känd teknik består av manuell rengöring. Rekommenderade rengöringsintervall varierar från en vecka till en månad, beroende på lokala förhållanden. ___., 10 45 20 25 35 l 453 539 N * Prior art Care and cleaning of transmitter and receiver windows according to known technology consists of manual cleaning. Recommended cleaning intervals vary from one week to one month, depending on local conditions.
Tekniskt problem Det har konstaterats att en beläggning med t ex vattendroppar på fönstren kan ge en dämpning av den till signaldetektorn inkommande reflekterade sig- nalen till ca IIH-1/6 av motsvarande vid rena fönster. Eftersom den reflek- terade signalen endast motsvarar en mycket liten del av varje utsând ljus- puls innebär den ytterligare reducerade signalstyrkan på reflexen beroende på vatten eller nedsmutsade fönster att mätningen blir osäkrare, kraven på signaldetektor än större m n.Technical problem It has been established that a coating with, for example, water droplets on the windows can provide an attenuation of the reflected signal received by the signal detector to approx. IIH-1/6 of the corresponding for clean windows. Since the reflected signal corresponds to only a very small part of each emitted light pulse, the further reduced signal strength of the reflection due to water or soiled windows means that the measurement becomes more uncertain, the requirements for signal detector even greater.
Rengöringen får ej ge upphov till mycket repor i fönsterglasen. eftersn dessa ger oönskade reflexer och en spridning av ljussignalen. fietta innroâr att fönstertorkararrangemangen som t ex används för rengöring av strålkastare och fönster på bilar med torkarblad som trycks relativt hårt mot fönstret ej är lämpliga, inte ens i samband med spolarvâtska.The cleaning must not give rise to a lot of scratches in the window glass. since these give unwanted reflections and a scattering of the light signal. fi This means that the window wiper arrangements used, for example, for cleaning headlights and windows on cars with wiper blades that are pressed relatively hard against the window are not suitable, not even in connection with washer fluid.
Speciellt för molnhöjdsmätare, där fönstren är riktade rakt upp not molnen, innebär nederbörd i form av regn och snö att den till signaldetektorn inkon- mande signalen får reducerad styrka. Här uppstår också ett rent praktiskt problem, nämligen besväret att ta sig ut till sândtagaren vid tråkig väder- lek för rengöring och att rengöringen måste pågå under hela den tid då neder- börd förekommer för att önskad verkan skall âstadkomas.Especially for cloud height meters, where the windows are directed straight up at the note clouds, precipitation in the form of rain and snow means that the signal coming to the signal detector has reduced strength. A purely practical problem also arises here, namely the inconvenience of getting out to the receiver in dull weather for cleaning and that the cleaning must last throughout the time when precipitation occurs in order to achieve the desired effect.
Eftersom nedfall av smuts och annan nederbörd är slupmâssigt fördelad i tiden, innebär den periodiskt återkommande rekommenderade rengöringen ingen garanti för att man har tillräckligt låg och godtagbar dämpning. fördelar anordningar enlit uppfinningen nedger att nämnda problen elimineras. nan har kontinuerlig övervakning av nedsmutsningsgraden och så fort en viss igrâns har passerats aktiveras en rengöringsanordning, son avlägsnar vatten » coon snnts från fänstren. ànordningen är utförd så att den ej kan ge repor i 5 10 15 20 25 30 .4 5 3 r fönstren. Då fönstren blivit rengjorda eller då erforderlig renhet uppnåtts stoppas rengöringsmekanlsmen.As precipitation of dirt and other precipitation is randomly distributed over time, the periodically recommended recommended cleaning does not guarantee that you have sufficiently low and acceptable damping. Advantages of devices according to the invention mean that said problems are eliminated. nan has continuous monitoring of the degree of soiling and as soon as a certain igrâns has been passed a cleaning device is activated, which removes water »coon snnts from the windows. the device is designed so that it cannot give scratches in 5 10 15 20 25 30 .4 5 3 r windows. When the windows have been cleaned or when the required cleanliness has been achieved, the cleaning mechanism is stopped.
Detta innebär att man alltid har en väl definierad övre dämpningsnivå och därmed en väl definierad maximal signalstyrkereduktion av den på glaset ligg- ande nedenšörden. Detta innebär också att signaldetektor och annan elektronik bättre kan utnyttjas för själva mätningen, varvid mätarens prestanda avsevärt förbättras.This means that you always have a well-defined upper attenuation level and thus a well-defined maximum signal strength reduction of the lower ground lying on the glass. This also means that signal detectors and other electronics can be better used for the measurement itself, whereby the meter's performance is considerably improved.
Anordningen enligt uppfinningen är utförd så att det normala mätförloppet ej påverkas.The device according to the invention is designed so that the normal measuring process is not affected.
Lösning av problemet Det fönsterglas som används i sådana sändtagare åránormalt antireflexbehand- u? / lat för att inte självt ge upphov till någon störhe dämpning av ljussignalerna.Solution to the problem The window glass used in such transceivers is normally anti-reflective. / lazy so as not to cause any disturbance to the attenuation of the light signals.
Då sândarfönstret får en yttre beläggning av t ex regndroppar från nederbörd erhålles reflexer från denna beläggning. En anordning enligt uppfinningen ut- nyttjar det så reflekterade ljuset som information om att t ex regn eller snö finns på fönstrets utsida. Molnhöjdsmätarens logikenhet avkânner denna reflexion och då en viss nivå har uppnåtts på den reflekterade signalen aktiveras eng rengöringsanordning. Denna kan bestå i att luft med högt tryck blåses läng; _fönstret, eller att en vippande eller roterande torkararm som ligger nära glas- ytan och har en mot glaset vänd öppen spalt eller hålrad och att tryckluft ochleller spolarvätska tillföres genom den ihåliga torkararmen så att en ridå av tryckluft ochleller vätska kommer att finnas mellan torkararmen och glaset och sveper över detta. Rengöringsprocessen kan styras så att en spolning sker först och därefter en torkning med den uppvärmda högtrycksblåsningen av luft längs fönstren. Då ingen eller tillräckligt låg reflexion från sândarglasets yta erhålles stoppas rengöringsanordningen.When the transmitter window receives an external coating of, for example, raindrops from precipitation, reflections are obtained from this coating. A device according to the invention uses the light so reflected as information that, for example, rain or snow is on the outside of the window. The logic unit of the cloud height meter senses this reflection and when a certain level has been reached on the reflected signal, a cleaning device is activated. This can consist of blowing air with high pressure for a long time; the window, or that a tilting or rotating wiper arm which is close to the glass surface and has an open gap or hollow row facing the glass and that compressed air and / or washer fluid is supplied through the hollow wiper arm so that a curtain of compressed air and / or liquid will be between and sweeps over this. The cleaning process can be controlled so that a flushing takes place first and then a drying with the heated high-pressure blowing of air along the windows. When no or sufficiently low reflection is obtained from the surface of the sander glass, the cleaning device is stopped.

Figure 1 further includes a light guide 10 and a drive unit 11 for the cleaning device 12.
Beskrivning av utföringsformer En utföringsform enligt fig 1 beskrivas. En anordning enligt uppfinningen utgör en tillsats till bl a molnhöjds, sikt- eller avståndsmåtare som arbe- tar enligt principen för optisk radar och utgör en integrerad del av sänd- tagaren.Description of embodiments An embodiment according to Fig. 1 is described. A device according to the invention constitutes an addition to, among other things, cloud height, sight or distance meters which work according to the principle of optical radar and form an integral part of the transceiver.
Reflexmätning kan ske från sändar- eller mottagarfönster. Eftersom det in- bördes avståndet mellan fönstren är litet, förutsätts att nedsmutsningen är lika på de båda fönstren. I princip kan man ha ett gemensamt fönster för sändare och mottagare, varvid beläggning (vattendroppar) på fönstret direkt ger reflexer som sprides ned i mottagaren och kan detekteras för start av rengöringsanordningen- I utförandet enligt fig 1 utnyttjas mätarens egen sändare och mottagare för att ta reda på om någon nedsmutsning har skett. Det från sändarglasets ut- sida reflekterade ljuset samlas och leds via en ljusledare 10 direkt till mottagaren. Den i mätaren ingående processorenheten 8 kompletteras program- mässigt med en speciell mätsekvens för denna reflexnâtning och vidare be- handling av signalen. Mätning av reflex från sändarglaset utförs, styrd med hjälp av en mätsekvens i mâtenheten, antingen före eller efter oln- höjds- eller siktmâtningen för att inte störa denna. Den uppmätta reflex- nivån jämförs i enheten 8 med ett förinställt värde som motsvarar maximalt tillåten nedsmutsning av sändarfönstret. Då nivån överskrids ges order till en drivkrets 11 som aktiverar rengöringsanordningen 12.Reflection measurement can take place from transmitter or receiver windows. Since the mutual distance between the windows is small, it is assumed that the soiling is the same on the two windows. In principle, one can have a common window for transmitter and receiver, whereby coating (water drops) on the window directly gives reflections that are spread down in the receiver and can be detected for starting the cleaning device- In the embodiment according to Fig. 1, the meter's own transmitter and receiver are used to take find out if any contamination has occurred. The light reflected from the outside of the transmitter glass is collected and conducted via a light guide 10 directly to the receiver. The processor unit 8 included in the meter is programmatically supplemented with a special measuring sequence for this reflex network and further processing of the signal. Measurement of the reflex from the transmitter glass is performed, controlled by means of a measuring sequence in the measuring unit, either before or after the oln, height or visibility measurement so as not to disturb it. The measured reflex level is compared in unit 8 with a preset value that corresponds to the maximum permitted contamination of the transmitter window. When the level is exceeded, an order is given to a drive circuit 11 which activates the cleaning device 12.
Rengöringsanerdningen 12 i fig 1 utgör en enhet som såsom tidigare indikerat kan utformas på olika sätt. I sitt enklaste utförande kan anordningen bestå av ett högtrycksaggregat sem blåser uppvärmd luft längs med fönstren. I industri- och andra områden med stora luftföroreningar, dvs där det kan för- väntas att nedsmutsningen av fönsterglasen blir stora, kan rengöringsannrd- ningen kompletteras för att ge ökad effekt- Kompletteringen kan bestå av att man applicerar ett vinnande eller roterande torkarblad med mjuk anläggnings- kant mot sändarfönstrets utsida. På grund av den reprisk som detta innebär bör den mjuka delen av torkarbladet ersättas av en torkararm son har en sot glaset vänd öppen spalt eller hålrad genom vilken tryckluft eller spelar-The cleaning device 12 in Fig. 1 constitutes a unit which, as previously indicated, can be designed in different ways. In its simplest embodiment, the device may consist of a high-pressure unit which blows heated air along the windows. In industrial and other areas with large air pollutants, ie where it can be expected that the contamination of the window glass will be large, the cleaning device can be supplemented to give increased effect. The supplementation may consist of applying a winning or rotating wiper blade with a soft system edge towards the outside of the transmitter window. Due to the reprisals that this entails, the soft part of the wiper blade should be replaced by a wiper arm son.
