Definitions
- the invention relates to an electric timer for an automatic time-control of the switching on and off of one or more electrically powered apparatuses and comprising an elec ⁇ tronic clock having a time scale with a graphic indication and a digital display and connected to a control circuit capable of actuating switching means so as to open and close an electric circuit and with memory means connected to the control circuit and a keyboard for setting the electronic clock and for setting the on and off times.
- timers automatically switching on and ,off electric apparatuses at specific predetermined times are known.
- mechanical clocks comprising riders circumferentially arranged on a movable dial closing and opening a circuit, and developed into purely electron ⁇ ic , microprocessor controlled clocks whereby the open/ close-programme is encoded in a memory and run while con ⁇ trolled by a digital clock (clock-unit).
- Timers are manu ⁇ factured in very great numbers and used in many ways for automatically controlling light, heat, and ventilation systems, in plug-connected apparatuses as well as in ma- chinery controls of various kinds.
- the various control programmes may furthermore be based on a day and night, a week or an annual cycle as well as comprise one or more channels .
- a timer of the type stated in the introduction to the specification is according to the invention characterised in that the keyboard comprises a combination of a) a func ⁇ tion shift key allowing the user to choose between a number of various mode functions of the control circuit, b) a switching on and off key allowing a switching on and off of the electric apparatus, and c) an advancing key for the time-settin , said keys being adapted to actuate the control circuit, and that the control circuit is adapted in such a manner that the user can transfer the control circuit into a so-called programming mode by pressing the function shift key one or more times whereby the control circuit is adapted simultaneously to provide a graphic indication of said mode, that the control circuit is adapt- ed so as to provide a graphic indication on the time scale of a time and simultaneously display said time on the digital display, that the control circuit is adapted in such a manner that the user can advance the time shown on the time scale to a desired switching on time, said time being displayed during the entire setting procedure both "an
- the set switching on time and the set switching off time is graphically shown on the associated time scale, and that the control circuit is adapted in such a manner that correspondingly the user can insert more switching on and off times which are also stored in a memory and displayed on the time scale, and that the control circuit is adapted in such a manner that after having encoded the desired number of switching on and off times in the memory of the control circuit the user can transfer the control circuit to a mode of automatic operation by pressing one or more times on the function shift key, the control circuit auto ⁇ matically switching on and off the electrically activated apparatuses at the set times in said automatic mode.
- the handling of the timer is so simple that without the assistance of directions for use the user can use the timer correctly and set a desired programme subse ⁇ quently appearing on the time scale provided.
- the user can always check the programme and for instance see whether a specific apparatus is to be switched on or off.
- the timer is so to speak "self- explanatory" as the user can determine the function and operation of the timer by the method of trial and error by pressing experimentally the three keys based on the reac ⁇ tions directly appearing on the time scale of the timer.
- the user keeps the switching on and off key pressed down while he lets the graphic time indication pass through the desired switching on interval by means of the advancing key.
- the user has the feeling of "drawing" the desired programme because on the display he draws so to speak a line corresponding to the desired switching on intervals.
- Fig. 1 illustrates substantially by way of a flow chart the main components of a timer according to the invention
- Fig. 2 illustrates an advantageous outline of the display and function keys of the timer
- Fig. 3 illustrates an example of the display at an initial stage of the programming of the timer
- Fig. 4 illustrates an example of the display at a terminat ⁇ ing stage of the programming of the timer
- Fig. 5 illustrates an example of the display when the programme has been encoded and the timer set for automatic operation
- Fig. 6 illustrates an example of the display when the timer is to be manually set.
- FIG. 1 illustrates an advantageous embo ⁇ diment of the timer according to the invention. It com ⁇ prises a single-chip microprocessor generally designated 10 and provided with the necessary number of inputs with a set of key means 14 actuating the functions implemented in the timer as well as a necessary number of outputs 16 controlling a display 18.
- the major portion of the front of the apparatus constitutes the display 18 which is a "liquid crystal" display or in short an LCD-unit.
- the display shows a time scale 20 with time indications for all 24 hours of the day and a dot or line indication for every 15 min.
- the scale 20 is associated with a movable scale cursor 22.
- the time scale need not cover all 24 hours of the day in all cases. Often it is only necessary to cover the usual working hour for instance from 7 a.m. to 5 p.m. , and in the latter case it is pos ⁇ sible to achieve a greater resolution of the indications of the scale and consequently a greater accuracy for the graphic indication than in the 24 hours case.
- a symbol field 24 associated with a movable symbol field cursor 26 as well as a digital clock display 28 is present, said display showing the hours and minutes.
- the symbol field includes four symbols, viz. a time symbol 32, a programming symbol 34, a symbol of the automatics 36, and a manual-symbol 38.
- the microprocessor or rather the chip comprises a ROM-unit 50 and a RAM-unit 52.
- the permanent programme for carrying out the various functions of the timer is encoded in the ROM-unit 50, and the functions applying here appear from the explanation stated below of the handl-
- the microprocessor com ⁇ prises furthermore an LCD-driver 54 and a timer 56 with an interrupt-function.
- the four latter units can be estab ⁇ lished by mask programming the chip whereby it is possible to minimize the costs of the apparatus because unnecessary facilities usually present in a microprocessor can be omitted. None, however, prevents the ROM, RAM, and said remaining units from being present as discrete outer units .
- the microprocessor is supplied with current from a battery 58 or a grid connected power supply 60 connected through a relay unit 62 to a driver 64 for the microprocessor 10.
- the presence of the timer/interrupt unit 56 ensures the least possible consumption of current, and the unit is controlled by a timer/clock unit 66, the basic frequency of which for instance is about 1 MHz.
- the above interrupt unit 56 counts pulses and releases an interrupt signal to the microprocessor at suitable intervals, for instance every second and half-second. In this manner the micropro- cessor performs part of a function in response to the performing programme encoded in the ROM unit 50 and the programme encoded in the RAM unit 52 inter alia including information on the switching on/off times defined by the user in question of the apparatus.
- the timer unit 56 releases signals controlling the switching on and off of the electrically activated appara ⁇ tuses .
- the microprocessor is controlled by a CPU-clock unit 68, the basic frequency of which in this connection can be as low as 75-100 kHz. The lower the frequency is the lower the current consumption is.
- the clock display 28 shows the time 00.
- the clock can be set on the actual time.
- the advancing key 44/46 is adapted to advance the time shown slowly or quickly, which appears clearly from the symbols used.
- a pressure on the function shift key or MODE key 40 implies that the microprocessor 10 is shifted into a programming mode which allows an encoding of the desired switching times or switching intervals in the RAM unit 52. Simultan ⁇ eously the symbol field cursor 26 moves and positions below the programming symbol 34. In this mode the user can advance the time scale cursor 22 by a pressure on the advancing key 44/46 until the first switching time has been reached. It should be noted here that the time scale cursor moves stepwise - with the indicated resolution covering 15 minutes each time - whereas the exact time is shown with a minute's accuracy on the clock display 28. When the first switching time has been reached, the IN/OUT key 42 is activated at the same time as the advancing key 44/46 is pressed down.
- the timer operates automatically and reacts on the encoded switching intervals in accordance with their encod ⁇ ing during the programming phase.
- the display appears for instance as shown in Fig. 5 wherein the symbol field indicates that the timer operates in the automatic mode, and where it is readable on the time scale that the time is now about 1.30 p.m. - the exact time is readable on the clock display 28 - and further that the switching interval lasts from about 6.30 a.m. to about 8.00 a.m.
- the indications on the time scale can only be given with an accuracy of about 15 minutes depending on the extent of the control period on the display.
- a pressing on the advancing key causes the scale cursor 22 to jump forwards to the first switching time, which appears on the clock display with an accuracy of 1 minute.
- Another pressing on the advancing key 44/46 causes the scale cursor 22 to move to the next switching time, which also appears on the clock display 28 with an accuracy of 1 minute. In this manner the exact switching times can be quickly provided. This procedure can also be performed in the manual-position.
- a timer of the above type provides a novel general view of the approximate switching times and switching Intervals and simultaneously it is easy to use because the program ⁇ ming of the timer is self-evident and does not imply a thorough study of accompanying directions for use.
- Variations can be performed which are based on a weekly programme allowing a leafing through thereof from one day of the week to the following, or an annual programme allow- ing a leafing f through from one week to the next, and fur ⁇ ther from one day of said week to the following day. It is also possible to connect the display with more channels allowing a leafing through the various channels , as well as all possible combinations of the above possibilities. These possibilities have been indicated by a dotted line in Fig. 1 by additional key means for "week", "day”, and "channel” .

Abstract
Dans un chronomètre électrique programmable pourvu d'un affichage (18) numérique (28) de l'heure réelle, l'affichage est complété par un champ de symboles (24) comprenant une pluralité de symboles et un curseur mobile (26) dans le champ de symboles. Ce curseur peut être déplacé par des organes manuels de changement de fonction (40, 50). L'affichage comprend en outre une échelle temporelle (20) portant sur un certain nombre des 24 heures d'une journée, facultativement sur toutes les heures d'une journée, associée à un curseur mobile (22). Ce curseur (22) peut être déplacé rapidement par des organes manuels d'avancement (44, 46, 50, 54). Finalement, un organe manuel indicateur (42, 44, 46, 52, 54) enregistre les heures et les intervalles de commutation codés et donne en même temps une indication graphique de ces heures et intervalles sur l'échelle temporelle (20) de l'affichage (18). Le chronomètre est ainsi d'utilisation facile, et donne à l'utilisateur une vue graphique des heures et intervalles réels de commutation.In a programmable electric chronometer provided with a digital display (18) of the real time, the display is completed by a symbol field (24) comprising a plurality of symbols and a moving cursor (26) in the symbol field. This cursor can be moved by manual function change devices (40, 50). The display further comprises a time scale (20) relating to a certain number of the 24 hours of a day, optionally to all the hours of a day, associated with a mobile cursor (22). This cursor (22) can be moved quickly by manual advancement devices (44, 46, 50, 54). Finally, a manual indicating unit (42, 44, 46, 52, 54) records the hours and the coded switching intervals and at the same time gives a graphical indication of these hours and intervals on the time scale (20) of the display (18). The stopwatch is thus easy to use, and gives the user a graphical view of the actual switching times and intervals.
