Opfindelsen angår et elektrisk kontaktur til automatisk tidsstyret ind- og udkobling af et eller flere elektrisk drevne apparater omfattende et elektronisk ur med en tidsskala med en grafisk markering og med en digital visning og af den i ind-5 ledningen til krav 1 angivne art.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an electrical contact clock for automatically timing and disabling one or more electrically driven apparatus comprising an electronic clock having a time scale with a graphic mark and a digital display and of the kind specified in the preamble of claim 1.

Der kendes mange forskellige udformninger af kontakture til automatisk ind- og udkobling af elektriske apparater på bestemte forindst i Ilede tidspunkter. Historisk er udviklingen 10 gået fra mekaniske ure, der med perifert anbragte ryttere på en bevægelig urskive sluttede og brød en strømkreds, til rent elektroniske, mikroprocessorstyrede ure, hvor tænd/slut-pro-grammet bliver kodet ind i et lager og eksekveres under styring af et digitalt ur (clock-enhed). Kontakture fremstilles i 15 meget stort antal og finder anvendelse mangfoldige steder til automatisk styring af lys-, varme- og ventilationsanlæg, i stikproptilsluttede apparater samt i maskinstyringer af forskellig art. De forskellige styreprogrammer kan endvidere være baseret på en døgn-, uge- eller årscyklus samt omfatte én el-20 ler flere kanaler.Many different designs of contact clocks are known for automatic switching on and off of electrical appliances at specific times in the past. Historically, the development has gone from mechanical clocks that connected peripherally mounted riders to a movable dial and broke a circuit, to purely electronic, microprocessor-controlled clocks, where the on / off program is encoded into a store and executed under the control of a digital clock (clock unit). Contact clocks are manufactured in 15 very large numbers and use a variety of places for automatic control of lighting, heating and ventilation systems, in plug-in appliances and in machine controls of various kinds. Furthermore, the various control programs may be based on a 24-hour, weekly or annual cycle and include one or more channels.

Udviklingen på elektronikområdet er naturligvis også nyttiggjort på dette felt til opnåelse af mere præcise ind- og udkoblingstider, større programkapacitet og flere kanaler i sam-25 me enhed. Imidlertid er denne udvikling sket på elektronikkens betingelser, hvilket har medført, at det indkodede styreprogram blev skjult for brugeren. Som eksempler herpå kan nævnes de internationale patentansøgninger PCT/US79/00980 (W0/01120) og PCT/US81/00346 (W0 81/02808) samt det tyske offentliggørel-30 sesskrift nr. 28 04 079. I modsætning hertil var styreprogrammet for mekaniske kontakture, hvilket stadigvæk er tilfældet, til at afløse direkte gennem placeringen af de forskellige ryttere. De fleste kendte elektroniske kontakture viser blot det aktuelle klokkeslet på digital form. Dersom brugeren øn-35 sker at kende det indlagte program i detaljer, bliver det nødvendigt gennem manipulation af et tastatur at "bladre" gennem programmet samt notere sig de herved fremfundne klokkeslæt forThe development in the field of electronics is of course also utilized in this field to achieve more precise switch-on and switch-off times, greater program capacity and multiple channels in the same unit. However, this development has occurred under the conditions of electronics, which has caused the encoded driver program to be hidden from the user. Examples of these are the international patent applications PCT / US79 / 00980 (W0 / 01120) and PCT / US81 / 00346 (W0 81/02808) as well as German Publication No. 28 04 079. In contrast, the Mechanical Control Program contact hours, which is still the case, to replace directly through the location of the various riders. Most known electronic contact clocks simply display the current time in digital form. If the user wishes to know in detail the program entered, it will be necessary, through manipulation of a keyboard, to "flip" through the program and note the resulting time for

5 Dette er på ingen måde brugervenligt.5 This is by no means user-friendly.

Dertil kommer, at programmeringen af kendte elektroniske kontakture ofte kan være kompliceret og kræve hyppige konsultationer af den tilhørende brugervejledning.In addition, the programming of known electronic contact clocks can often be complicated and require frequent consultations with the corresponding user manual.

Det er kendt at indrette en tidsskala med en grafisk markering af koblingstidspunkterne, se f.eks. engelsk patentansøgning nr. 2.054.908, japansk patentansøgning nr. 55-63788 og europæisk patentansøgning nr. 119.312. Ingen af disse ansøgninger 15 angiver imidlertid, hvorledes et kontaktur skal være indrettet, for at brugeren umiddelbart kan anvende det uden særlig instruktion og uden brug af brugsanvisning.It is known to arrange a time scale with a graphic marking of the switching times, see e.g. English Patent Application No. 2,054,908, Japanese Patent Application No. 55-63788 and European Patent Application No. 119,312. However, none of these applications 15 specify how a contact clock must be arranged so that the user can immediately use it without special instruction and without the use of instructions.

Det engelske offentliggørelsesskrift nr. 2.054.908 viser et 20 kontaktur, der kan styre otte elektriske kredsløb, der hver især kan programmeres separat med 69 mulige tilstandsændringer per dag. Programmet vises ved hjælp af 69 LCD- eller LED-indi-katorer på en stribe (7) og kan vises for den nærværende dag eller for en hel uge ad gangen. Derudover er der et ciffer-25 display (2,3), der kan vise dagens timer eller ugenummeret i et år samt yderligere cifre (4,5), der angiver minutter og endelig et ciffer (6), der kan angive ugedage. Derudover er der et stort antal trykknapper - en for hver dag samt en ekstra ottende - til et specielt program og knapper til at juste-30 re for sommertid og vintertid. Der er intet i skriftet, der tyder på, at dette kontaktur skulle være særligt nemt at programmere eller anvende.English Publication No. 2,054,908 discloses a 20 contact clock which can control eight electrical circuits, each of which can be programmed separately with 69 possible state changes per day. The program is displayed using 69 LCD or LED indicators on a strip (7) and can be displayed for the current day or for a whole week at a time. In addition, there is a digit-25 display (2,3) that can show the day's hours or week number for a year, as well as additional digits (4,5) indicating minutes and finally a digit (6) which can indicate weekdays. In addition, there are a large number of push buttons - one for each day as well as an extra eighth - for a special program and buttons for adjusting 30 for summer time and winter time. There is nothing in the script to suggest that this contact clock should be particularly easy to program or use.

Et kontaktur af den i indledningen nævnte art er ifølge opfin-35 delsen ejendommelig ved, at tastaturet kun har een funktionsskiftetast (40), der er forbundet til styrekredsen (10), og at styrekredsen er indrettet til at indtage 3According to the invention, a contact clock of the kind mentioned in the introduction is characterized in that the keyboard has only one function change key (40) which is connected to the control circuit (10) and that the control circuit is arranged to take 3.

1) en initialtilstand for indstilling af løbende tid, 2) en programmeringstilstand for indstilling af de ønskede tidspunkter for ind- og udkobling, 5 3) en automatisk tilstand for normal funktion ifølge programmeringen, og 4) at displayet (18) er indrettet til at give en indikation 10 (26,32-38) af styrekredsens aktuelle tilstand.1) an initial state for setting the current time, 2) a programming mode for setting the desired times for switching on and off, 5 3) an automatic mode for normal operation according to the programming, and 4) the display (18) is arranged to give an indication 10 (26,32-38) of the current state of the control circuit.

Herved opnås, at betjeningen af kontakturet er så enkel, at en bruger uden hjælp af en brugsanvisning kan anvende uret korrekt og indstille et ønsket program, som derefter direkte 15 vises på den indrettede tidsskala, således at en bruger altid kan kontrollere programmet og f.eks. se, om et bestemt apparat skal være tændt eller slukket. Med andre ord opnår man, at kontakturet så at sige er "selv-forklarende", idet brugeren blot ved at prøve sig frem ved forsøgsvis at trykke på de tre 20 taster ud fra de reaktioner, brugeren direkte kan se på kontakturets tidsskala, kan slutte sig til, hvorledes uret virker, og hvorledes det skal betjenes.The result is that the operation of the contact clock is so simple that, without the help of a user manual, a user can use the clock correctly and set a desired program, which is then directly displayed on the arranged time scale, so that a user can always control the program and f. eg. see if a particular appliance should be turned on or off. In other words, one obtains that the contact clock is, so to speak, "self-explanatory", in that the user simply by trying himself forward by experimentally pressing the three 20 keys based on the reactions the user can see directly on the contact time scale, can end say how the clock works and how it should be operated.

I en foretrukken udførelsesform ifølge krav 4 holder brugeren 25 ind- og udkoblingstasten nede, medens han ved hjælp af avanceringstasten 1 ader den grafiske tidsmarkering gennemløbe det ønskede indkoblingsinterval. Da han samtidig iagttager tidsskalaen med den grafiske markering af tidspunkterne, vil brugeren få en fornemmelse af at "tegne" det ønskede program, 30 idet han så at sige tegner en streg ud for de ønskede indkob-1 i ngsi ntervaller.In a preferred embodiment according to claim 4, the user 25 holds down the on and off key while, by means of the advance key 1, the graphical time mark passes through the desired switch-on interval. As he simultaneously observes the time scale with the graphical marking of the times, the user will have a feeling of "drawing" the desired program, 30 drawing a line next to the desired shopping-in intervals.

Før der gås videre med beskrivelsen af blokdiagrammet i fig.Before proceeding with the description of the block diagram in FIG.

30 1, henvises til fig. 2 for en nærmere redegørelse af kontakt urets og navnlig displayets geometriske udformning. Størsteparten af apparatets forside beslaglægges af displayet 18, som er et "flydende krystal"-display eller på kort form en LCD-en-hed. På displayet er vist en tidsskala 20 med timemarkeringer 35 for alle døgnets 24 timer og en prik- eller stregmarkering for hvert kvarter. Til skalaen 20 er knyttet en flytbar skalamarkør 22. Det skal i parentes bemærkes, at tidsskalaen ikke i 530 1, reference is made to FIG. 2 for a detailed explanation of the contact's geometric design and, in particular, the geometric shape of the display. Most of the front of the apparatus is seized by the display 18, which is a "liquid crystal" display or, in short form, an LCD unit. The display shows a time scale 20 with hour markings 35 for all 24 hours of the day and a dot or dash mark for each quarter. Attached to the scale 20 is a movable scale marker 22. It should be noted in parentheses that the time scale does not in 5

alle tilfælde behøver at dække alle døgnets 24 timer. Der vil ofte kun være behov for at dække den normale arbejdstid fra 7 til 17 for eksempel, og i dette tilfælde kan man opnå en større opløsning for skalaens markeringer og derved større nøjag-5 tighed for den grafiske indikering.all cases need to cover all 24 hours of the day. Often, there will only be a need to cover the normal working time from 7 to 17, for example, and in this case a greater resolution can be obtained for the scale markings and thereby greater accuracy for the graphical indication.

Oven over tidsskalaen 20 findes et symbolfelt 24 med tilhørende flytbart symbolfelt-markør 26 samt et digitalt ur-display 28 visende timer og minutter.Above the time scale 20 there is a symbol field 24 with associated movable symbol field marker 26 as well as a digital clock display 28 showing hours and minutes.

Symbolfeltet indeholder fire symboler, et klokkeslet-symbol 32, et programmerings-symbol 34, et automatik-symbol 36 og et manuel-symbol 38.The symbol field contains four symbols, a clock symbol 32, a programming symbol 34, an automatic symbol 36 and a manual symbol 38.

15 Nedenunder displayet 18 er vist tre funktionstaster, en funktionsskifte- eller MODE-taste 40, en IND/UD- eller 0N/0FF-taste 42 og en avanceringstaste 44/46.Below the display 18 are shown three function keys, a function change or MODE key 40, an IND / OUT or 0N / 0FF key 42 and an advance key 44/46.

Ovennævnte funktionstaster genfindes i fig. 1 på indgangene 14 20 til mikroprocessoren 10. I denne fig. er vist, at mikroprocessoren eller rettere selve chip’en indeholder en ROM-enhed 50 og en RAM-enhed 52. I ROM-enheden 50 er indlæst det faste program til eksekvering af kontakturets forskellige funktioner, og hvilke funktioner, det drejer sig om, vil fremgå nærmere 25 nedenfor under forklaringen af kontakturets betjening og drift. Desuden indeholder en mikroprocessor en LCD-driver 54 og en timer 56 med en interrupt-funktion. De fire sidstnævnte enheder kan realiseres ved maskeprogrammering af chip'en, hvorved det bliver muligt at billiggøre apparatet, idet unød-30 vendige faciliteter, der normalt findes hos en mikroprocessor, kan udelades. Der er dog intet i vejen for, at ROM-, RAM- og nævnte øvrige enheder kan forefindes som diskrete ydre enheder.The above function keys are found in FIG. 1 of the inputs 14 20 of the microprocessor 10. In this FIG. It is shown that the microprocessor or rather the chip itself contains a ROM unit 50 and a RAM unit 52. In the ROM unit 50 is loaded the fixed program for executing the various functions of the contact clock and the functions involved. will appear in detail below 25 during the explanation of the operation and operation of the contact clock. In addition, a microprocessor contains an LCD driver 54 and a timer 56 with an interrupt function. The four latter units can be realized by mask programming the chip, thereby enabling the device to be billed, leaving out unnecessary facilities normally found at a microprocessor. However, there is nothing in the way of ROM, RAM, and the other devices mentioned as discrete external devices.

35 Mikroprocessoren strømforsynes fra et batteri 58 eller en netdel 60, som via en relæ-enhed 62 er forbundet til en driver 64 for mikroprocessoren 10.The microprocessor is powered from a battery 58 or a power portion 60 which is connected via a relay unit 62 to a driver 64 for the microprocessor 10.

Tiraer/interrupt-enheden 56, hvis tilstedeværelse sikrer det mindst mulige strømforbrug, styres af en timer/clock-enhed 66, hvis grundfrekvens er ca. 1 MHz, f.eks. Nævnte interrupt-enhed 56 tæller impulser og afgiver med passende mellemrum, f.eks.The timer / interrupt unit 56, the presence of which ensures the least possible power consumption, is controlled by a timer / clock unit 66 whose fundamental frequency is approx. 1 MHz, e.g. Said interrupt unit 56 counts pulses and emits at appropriate intervals, e.g.

5 hvert hele eller halve sekund, et interrupt-signal til mikroprocessoren, som derved udfører en delfunktion afhængig af det i ROM-enheden 50 indlæste eksekveringsprogram og det i RAM- enheden 52 indkodede program, som blandt andet består af information om tænd/sluk-tidspunkter defineret af den pågældende 10 bruger af apparatet. Timerenheden 56 afgiver på et antal udgangsporte styresignaler til ind- og udkobling af de elektrisk drevne apparater.5 every full or half second, an interrupt signal to the microprocessor, thereby performing a sub-function depending on the execution program loaded in the ROM 50 and the program encoded in the RAM 52 which includes, inter alia, information on power-on times defined by that particular 10 user of the apparatus. The timer unit 56 outputs control signals for a number of output ports for switching on and off the electrically powered appliances.

Selve mikroprocessoren styres af en CPU-clockenhed 68, hvis 15 grundfrekvens i denne sammenhæng kan være så lav som 75-100 kHz. Strømforbruget er des mindre, jo lavere frekvensen er.The microprocessor itself is controlled by a CPU clock unit 68, whose fundamental frequency in this context may be as low as 75-100 kHz. The lower the power consumption, the lower the frequency.

Når apparatet tilsluttes en strømkilde, vil symbolfel tmarkøren 26 automatisk stille sig under klokkesletsymbolet 32, medens 20 skalamarkøren 22 vil stille sig under klokken nul på tidsska laen 20. Samtidig hermed vil urdisplayet 28 vise klokken 00. Ved tryk på avanceringstasten 44/46 kan uret 28 stilles på det aktuelle klokkeslet. Avanceringstasten 44/46 er indrettet til henholdsvis langsom og hurtig fremtælling, hvilket fremgår ty-25 deligt af de anvendte symboler.When the appliance is connected to a power source, the symbol error marker 26 will automatically position below the clock symbol 32, while 20 the scale cursor 22 will set below zero at the time slot 20. At the same time, the clock display 28 will show the clock 00. By pressing the advanced key 44/46 the clock can 28 is set to the current time. Advance key 44/46 is arranged for slow and fast counting, respectively, as is clear from the symbols used.

Et tryk på funktionsskiftetasten eller MODE-tasten 40 bevirker, at mikroprocessoren 10 bringes i en programmeringstilstand, således at de ønskede koblingstidspunkter eller kob-30 1ingsintervaller kan indlæses i RAM-enheden 52. Samtidig her med skifter symbolfelt-markøren 26 plads og stiller sig under programmerings-symbolet 34. I denne tilstand skal brugeren avancere tidsskalamarkøren 22 ved et tryk på avanceringstasten 44/46, indtil det første koblingstidspunkt er nået. Det skal 35 her bemærkes, at tidsskalamarkøren bevæger sig springvist -med den viste opløsning for et kvarter ad gangen - medens det nøjagtige tidspunkt vises med et minuts nøjagtighed på urdis- 7Pressing the function switch key or MODE key 40 causes the microprocessor 10 to be put into a programming mode so that the desired switching times or switching intervals can be entered into the RAM unit 52. At the same time, the symbol field marker 26 is changing and positioning itself below the programming symbol 34. In this mode, the user must advance the time scale marker 22 by pressing the advance key 44/46 until the first switching time is reached. It should be noted here that the time scale marker moves in a jump - with the displayed resolution for one block at a time - while the exact time is displayed with a minute accuracy of clockwise 7.

playet 28. Når det første koblingstidspunkt er nået, aktiveres IND/UD-tasten 42 samtidig med, at avanceringstasten 44/46 nedtrykkes. Ved den samtidige nedtrykning af nævnte to taster påbegyndes tegningen af en sort streg på displayet, jf. således 5 fig. 3, hvor det af afbildningen fremgår, at det første koblingstidspunkt er sat til kl. 6.30, og at skalamarkøren 22 er avanceret til klokkeslettet 6.45, således som vist på urdisplayet 28. Dette fortsættes der med, indtil udkoblingstidspunktet er nået, hvorefter tasterne slippes. Alternativt kan 10 man indrette det således, at IND/UD-tasten er en push-push tast, således at en vedvarende nedtrykning af denne taste ikke er nødvendig under denne procedure.the play 28. When the first switching time is reached, the IND / OUT key 42 is activated at the same time as the advance key 44/46 is pressed. When the two keys are pressed simultaneously, the drawing of a black line on the display begins, cf. 3, where it is clear from the diagram that the first switching time is set at 11.00. 6.30, and the scale cursor 22 is advanced to the time 6.45, as shown on the clock display 28. This is continued until the switch-off time is reached, after which the keys are released. Alternatively, it can be arranged so that the IND / OUT key is a push-push key, so that sustained pressing of this key is not required during this procedure.

Situationen er nu den i fig. 4 viste, det fremgår her, at ud-15 koblingstidspunktet er sat til kl. 8.00, og det fremgår tydeligt af displayets indikering, at koblingsintervallet, der er markeret med en sort streg, går fra kl. 6.30 til kl. 8.00. Ovennævnte procedure kan gentages for vilkårlige tidsintervaller inden for det pågældende døgn, og når denne programme-20 ringsfase er tilendebragt, aktiveres MODE-tasten 40 på ny, hvilket bringer mikroprocessoren 10 over i automatik-tilstanden. Dette indikeres på displayet ved, at symbolfelt-markøren 26 nu stiller sig under automatiksymbolet 36.The situation is now the one in fig. 4, it appears here that the switch-off time is set to 1 p.m. It is clear from the display's indication that the switching interval, marked with a black line, runs from 10 am. 6:30 to 6 p.m. 8.00. The above procedure can be repeated for arbitrary time intervals within the particular day, and when this programming phase is completed, the MODE key 40 is reactivated, which brings the microprocessor 10 into automatic mode. This is indicated on the display by the symbol field marker 26 now positioning below the automatic symbol 36.

25 Kontakturet opererer nu automatisk og reagerer på de indkodede koblingsintervaller, som de blev indlæst under programmeringsfasen. Kl. 13.30 vil displayet f.eks. have det i fig. 5 viste udseende, hvor det i symbolfeltet er markeret, at kontakturet opererer i automatik-tilstanden, og hvor det på tidsskalaen 30 kan aflæses, dels at klokken er ca. 13.30 - det nøjagtige klokkeslet kan aflæses af urdisplayet 28 - dels at koblingsin-tervallet strækker sig fra kl. ca. 6.30 til ca. 8.00. Markeringerne på tidsskalaen kan kun gives med en nøjagtighed inden for ca. et kvarter afhængigt af, hvor lang en styringsperiode 35 der er bredt ud på displayet.25 The contact clock now operates automatically and responds to the encoded switching intervals as they were entered during the programming phase. Kl. At 13.30, the display will, for example. having it in fig. 5, where the contact clock operates in the automatic mode and where it can be read on the time scale 30, and that the clock is approx. 13.30 - the exact time can be read from the clock display 28 - partly that the switching interval extends from 11.00 to 16.00. ca. 6.30 to approx. 8.00. The markings on the time scale can only be given with an accuracy within approx. a neighborhood depending on how long a control period 35 is widespread on the display.

Dersom man ønsker koblingstidspunkterne oplyst med større nøjagtighed, vil et tryk på avanceringstasten få skalamarkøren 22If you want the switching times to be illuminated with greater accuracy, pressing the advance key will have the scale marker 22

DK 163842 BDK 163842 B

8 til at hoppe frem til det første koblingstidspunkt, som udlæses på urdisplayet med et minuts nøjagtighed. Et nyt tryk på avanceringstasten 44/46 bringer skalamarkøren 22 frem til det næste koblingstidspunkt, som ligeledes udlæses på urdisplayet 5 28 med et minuts nøjagtighed. På denne måde kan oplysning om de nøjagtige koblingstidspunkter hurtigt tilvejebringes. Denne procedure kan også foregå i manuel-sti 11 ingen.8 to jump to the first switching time, which is read out on the watch display with one minute accuracy. A new press of the advance key 44/46 brings the scale cursor 22 to the next switching time, which is also read out on the clock display 5 28 with one minute accuracy. In this way, information on the exact switching times can be obtained quickly. This procedure can also be performed in manual path 11.

I tilstanden "manuel” kan kontaktfunktionen betjenes på samme 10 måde som et kiprelæ ved tryk på IND/UD-tasten 42. Denne situation er vist i fig. 6.In the "manual" mode, the switching function can be operated in the same way as a tilt relay by pressing the IND / OUT key 42. This situation is shown in Fig. 6.

Et kontaktur af ovenfor beskrevne art giver brugeren et hidtil ukendt overblik over de omtrentlige koblingstidspunkter og 15 koblingsintervaller og er samtidig brugervenligt, idet programmeringen af kontakturet giver sig selv og ikke forudsætter et timelangt studium af en medfølgende betjeningsvejledning.A contact watch of the kind described above gives the user an unprecedented overview of the approximate switching times and 15 switching intervals and is also user-friendly, as the programming of the contact watch gives itself and does not require an hour-long study of the accompanying operating instructions.

Selv om opfindelsen i det foregående udelukkende er blevet 20 forklaret ved beskrivelsen af et kontaktur, som er baseret på en døgncyklus, kan der tænkes andre for en gennemsnitsfagmand selvfølgelige modifikationer, ændringer eller tilføjelser, som ligger helt inden for rammerne af den foreliggende opfindelse, således som denne er defineret gennem nedenstående patentkrav.While the foregoing invention has been explained solely by the description of a 24-hour contact clock, other obvious modifications, modifications or additions which are entirely within the scope of the present invention may be conceived by others of ordinary skill in the art. as defined by the claims below.
