Definitions

  • the invention relates to a method and a device for setting and displaying the switching times in a digital time switch.
  • a quartz crystal is provided, the vibrations of which are reduced by a frequency divider circuit and control an electronic minute, hour and day counter, the time and day of the week being indicated by a liquid crystal display.
  • the time values for the switching commands can be entered into a memory using a keyboard, so that, for. B. at 6:00 a.m. the heating is switched to «NORMAL and at 10:00 p.m. again to « REDUCED.
  • two switching points are set in the daily program, namely switching on at 6 a.m. and switching off at 10 p.m. Switching takes place between two switching states, namely «NORMAL and « REDUCED •.
  • other switching states would also be possible, e.g. B. switching between «NORMAL» and «OFF •.
  • the known time switch In the known time switch, different switching times can be programmed for the working days and for the weekend. Different daily programs can therefore be used for the working days and the weekend.
  • the known time switch also has several channels, so that, for example, the heating on the south side of the house via a first channel, the heating on the north side of the house via a second channel and the hot water preparation via a third channel (e.g. an electric boiler) ) can be controlled.
  • the well-known digital time switch also takes the inertia of the heating system into account by automatically switching on a lead time. If, for example, the user sets the heating to 6 a.m. and the lead time is one hour, the time switch switches at 5 a.m. Correspondingly, the switch from «NORMAL to « REDUCED "takes place an hour earlier.
  • GB-A-2091 913 describes a time-controlled heating controller which has an analog display with 48 display elements arranged along a line. Each of these display elements represents half an hour.
  • the time can be set with several push buttons. To change a set on or off time, a corresponding push button is pressed. The newly set time is shown on the analog display.
  • the disadvantage is that the user cannot easily recognize the effect of his manipulations. After manipulation, it is no longer possible to see where a change should take place or has taken place on the analog display.
  • GB-A-2 054 908 describes a time switch with an analog display which has 96 display elements arranged along a line or circle. Each of the display elements represents a quarter of an hour. In addition, a digital display is provided for the hours, minutes and day of the week. For reading the stored program or for programming, each of eight switching channels can be selected using a slider. This timer also has the disadvantage that the user cannot easily recognize the effects of his manipulations on the analog display.
  • this is achieved by changing the set on or off time for a predetermined switching state, e.g. B. «NORMAL by operating a switching element, for. B. a key, a cursor at the beginning or at the end of the route for this switching state and then the cursor is moved so far along the line until a segment is reached that corresponds to a desired time.
  • a switching state e.g. B. «NORMAL
  • the cursor is automatically placed at the beginning or end of the route when the corresponding switching element is actuated.
  • the cursor can then expediently be moved in two directions by actuating a corresponding switching element.
  • the number of switching elements can be reduced.
  • a digital display of the switching time is also expediently carried out simultaneously with the movement of the cursor, that is to say with the analog time display. This enables the switching points to be set precisely.
  • the cursor is expediently accelerated to a maximum speed after actuation of a switching element during a predetermined start-up time. This makes it possible to stop the cursor and thus also the digital display by releasing the switching element shortly before the desired switching time, the cursor and the digital display then running relatively slowly when the switching element is actuated again, so that when the desired value is reached the The button can be released in time and this value becomes the switching point.
  • the setting of a switching point can also be facilitated by briefly pressing the cursor one increment, e.g. B. an increment of ten minutes. This advance can be followed on the digital display.
  • digital time switches generally provide different daily programs for the working days and for the weekend. Furthermore, various switching channels are often provided. In such cases, it is expedient if one day program after the other can be selectively displayed from the first to the last switching channel by actuating a further switching element.
  • the order in which the daily programs are displayed can be such that a switch is made from one daily program to the other daily program of a switching channel, then from the last daily program of the first switching channel to the first daily program of the following switching channel and finally back to the first after the last daily program of the last switching channel Daily program of the first switching channel and / or back to normal operation. After the last daily program has been programmed, the programming of the time switch is completed, so that an automatic switch back to normal operation is advisable.
  • the display segments are advantageously arranged in one or more circles. This arrangement is space-saving and can therefore be easily implemented in a liquid crystal display. But it would also be possible to display segments in one or more loops, e.g. B. one or more circles to arrange. Such an arrangement is space-saving and can therefore be easily implemented in a liquid crystal display.
  • the display unit additionally has a display for the number of free switching points.
  • the display unit In order to get by with as few or as cheap electronic components as possible, usually only a limited number of switching points can be provided. The user is therefore happy if he knows at any time when setting the time switch how many switching points he still has available.
  • a switching device for. B. a button provided to display the individual daily programs in the same or different switching channels one after the other.
  • the day programs then form a loop, so to speak, that one day program after the other is displayed by pressing the button, whereby switching from one channel to another automatically.
  • the display can show both the channel and the days of the week, so that it can be seen at any time whether, for example, the daily program is shown for the south or north side of the house or for hot water preparation and whether it is the daily program for the working days or for the weekend.
  • a switching device for entering a standard program is expediently provided. This enables the user to easily enter a standard program. After entering the standard program, you can easily create a new program by changing this program.
  • Figure 1 shows the embodiment of a digital timer 10 designed for use in heating and air conditioning systems.
  • the display unit 11 can represent two operating states. In the normal state, the digital display 19 shows the time, with the colon 35 flashing. In the programming state, the colon does not flash and the setting time is displayed. But even during the programming process, the timer continues to run normally and controls the connected system according to the previous program.
  • the display unit 11 is designed as a liquid crystal display. Liquid displays are relatively cheap and require very little energy. To operate the time switch, six control buttons 12 to 17 are provided, of which the buttons 12, 16 and 17 can advantageously only be operated with a pointed object because they only have to be used rarely. However, buttons 13 to 15 can be operated with your finger. The function of the keys 12 to 17 is easier to understand if the liquid crystal display 11 is viewed beforehand. The following description of the liquid crystal display 11 is given with reference to FIG. 2.
  • FIG. 2 shows the different parts which can be made visible on the liquid crystal display by means of corresponding electrical signals.
  • a display 21 is provided for the days of the week.
  • the switching state, e.g. B. «ON or « OFF is shown by arrows 23 and 25 respectively. These states correspond to the switching on or off of a contact of the time switch.
  • the functions of the corresponding contact can be different, e.g. For example, switching the heating system from «REDUCED to « NORMAL and from «NORMAL to « REDUCED or switching a boiler on or off.
  • the symbols 27, 28, 29 indicate the switching channels.
  • a display 31 is provided, which shows the number of switching points still free during programming.
  • the arrangement of display segments 33 shown has the advantage that the duty cycle, z. B. the duty cycle of normal operation of a central heating can be displayed graphically.
  • a segment is represented by the activated segments 33, the beginning and the end of which represent switching points.
  • the start shows the switch-on time and the end the switch-off time. It is therefore immediately apparent from the state shown in FIG. 1 that the heating switches on normal operation at 6:00 a.m. and switches off again at 10:00 p.m. However, this statement still needs to be clarified.
  • the accuracy of the analog display formed by the segments 33 is of course limited by the duration of the segments, which is 20 minutes. It would therefore be possible for the digital clock to be set so that the heating switches on at 6.10 a.m.
  • heating systems have a certain inertia. It is therefore expedient to design a digital clock intended for heating systems in such a way that a so-called lead time is provided. In this case, the actual switching process does not correspond to the switching point set by the user, but is brought forward according to the inertia of the heating system. As mentioned in the introduction, this has already been achieved in known digital time switches, so that further explanations about it are unnecessary.
  • Figure 1 shows the display in normal operation of the timer. It's 8:25 a.m. on Tuesday.
  • the flashing colon 35 indicates normal operation.
  • the display 27 shows that the first switching channel is shown, and the visible switching segments 33 show that the first switching channel is in the “ON STATE” from approximately 6:00 a.m. to 10:00 p.m.
  • the time switch 10 has three switching channels. You can switch from one switching channel to another by pressing button 13.
  • the second switching channel is indicated by the display 28 (FIG. 2). It is shown what is on the day represented by the display 21; namely Tuesday, acts as a switching program in the second channel.
  • button 13 is then pressed again, the system switches to the third channel, as indicated by display 29 (FIG. 2). In this exemplary embodiment, this is the last available channel. Pressing the button 13 again switches back to channel 1, that is to say to the position shown in FIG. 1. Please note that this mode of operation applies to the normal state of the watch. In the programming state, the daily program for working days is switched to the daily program for the weekend. Only then will the switch to the first daily program of the next channel take place the next time the button is pressed.
  • buttons 16 and 17 are used to set the time switch in a manner known per se, so that a more detailed description of these functions is unnecessary.
  • the key 12 is used to enter the standard program. It is therefore only necessary to press this button to activate the corresponding standard daily programs for the various channels.
  • the user first presses the button 15.
  • the cursor now moves, as shown in FIG. 3, to the number of hours 8.
  • the digital display 19 switches the setting time in ten-minute steps.
  • the user releases button 15.
  • the new switch-on point is now set to 8:00 a.m.
  • the switch-off time is to be set to 1:00 p.m.
  • the user moves the cursor by holding down the button 14 until after 1:00 p.m. and releases the button as soon as 1:00 p.m. appears on the digital display. If he now presses key 15, the cursor continues to run. However, since it is to be switched on again at 4 p.m., he releases button 14 when the number 4 p.m. appears on the digital display.
  • the programming shown in FIG. 3 has thus been achieved. If the user stops manipulating, e.g. B. switches to another daily program by pressing the key 13, then returns after a predetermined time, for. B. two minutes after releasing the button 14, the timer back to normal.
  • the time is again shown on the digital display 19, which can be seen from the flashing colon 35.
  • the display is therefore as in FIG. 1, except that the segments between 6 and 8 and 13 and 16 are no longer visible.
  • the deletion of these segments is indicated in FIG. 3 by a dashed line.
  • button 15 If button 15 is then pressed, it continues to run until the operator releases button 15 at 17.00 and thus sets a new switch-on point.
  • the key 14 is then pressed so that the cursor runs and stops until the previous switching point of 10:00 p.m. By continuously pressing or releasing and pressing again, the cursor moves again, whereupon the operator releases the key 14 when the number 23.00 appears in order to initiate the setting of the switch-off point there.
  • buttons 14 and 15 are continuously pressed, display 19 switches relatively quickly in ten-minute steps and the cursor also moves quickly. However, if the key is released briefly, the advance in ten-minute steps is relatively slow at first. However, there is an acceleration until the normal speed is reached. So should the display on a certain setting, for. B. 23.00 brought, it is advantageous to let go of the key 14 at about 22.30 and then pressed again until 23.00 has been reached. However, it is also possible to switch gradually by briefly pressing until 23.00 has been reached.
  • Figure 5 shows a block diagram of the time switch. It is a simplified diagram, whereby only the most important functions are visible.
  • the keys 12 to 17 are connected to the input control 37, which has outputs for the channel and day program selection circuit 39, for the cursor control 41 and for the ramp circuit 43.
  • the ramp circuit 43 controls the speed at which the counter 45 delivers pulses to the cursor control 41 and display control 49.
  • the counter 45 also supplies the setting time with hour and 10-minute information to the switching time memory 47.
  • the switching point counter 51 counts down by one each time a switching point is set in order to display 11 the number of switching points which can still be programmed. However, if switching points are deleted, the switching point counter counts up.
  • the timer 53 supplies time signals to the display controller 49, so that the time normally appears on the display 11.
  • time signals are also supplied to the comparator 55, which compares these time signals with the switching times stored in the switching time memory 47 and outputs a signal to the switching command output 57 if they match. Since the switching time memory 47 additionally supplies a signal for determining the channel, the command output to the correct channel takes place if the switching time of the timer and the stored switching time match.
  • the invention is not limited to the embodiment shown in the block diagram. Rather, modern electronics, in particular microprocessor technology, offer even more possibilities for realizing the idea on which the present invention is based.
