Definitions

  • the invention relates to a time switch according to the preamble of claim 1.
  • Generic devices are known for example from EP-OS O 254 525 or from EP-OS O 339 373. They have numerous switch handles acting on a digital display. Above all, they serve to set the internal time correctly and, if necessary, to query certain switching processes or to specify or change them in a time-assigned manner via visual user guidance. In practice, however, it has been shown that not only for the technical layman, the operation of such devices, despite the visual aids, is extremely difficult and therefore prone to errors, even deterrent, which is why the theoretical spectrum of all operating and switching options when using such devices is never can be exploited.
  • the digital display is at risk of malfunction, particularly in harsh environmental conditions, such as when using the device in a boiler room or in a workshop, since the sensitive electromechanical connections between the display decoding circuit and the digital display are interrupted by vibrations, temperature influences or foreign matter deposits or other malfunctions.
  • the manufacturing outlay for training is also a Display decoding and for the electro-optical display including its assembly and the effort for installation and wiring of the electromechanical switches in the front wall of a control device, which often has to be movable for service access as a door, very high compared to the value of the actual electronic clock - And counting circuits for obtaining times that can be queried for switching processes.
  • the invention is based on the object of designing a time switch of the generic type in such a way that it saves on operation, particularly for the layman, for operation within the scope of the everyday requirements, while saving on manufacturing outlay and reducing malfunction-prone functional components.
  • the basic idea of the solution according to the invention is therefore based on the consideration of dispensing with any effort for an operator-side time adjustment of the switching device if its internal clock in the form of the time-operated clock generator with delivery from the production side is already running correctly and continues to run without interruption regardless of the storage or installation status over the entire period of the foreseeable operational readiness.
  • This can be achieved by autonomous operation using a long-term battery, such as a lithium battery available on the market, which may be buffered from a network as a power reserve during normal operation of the timer.
  • a long-term battery such as a lithium battery available on the market
  • an optical time display of the constantly correct internal clock of the switching device is no longer necessary, a complex electro-optical presentation of current or changeable switching programs can also be dispensed with. If an electro-optical display is nevertheless present, it can of course also be used, for example, to display times, switch positions and / or current measured values; it is crucial that the effort for user intervention in the course of time is eliminated. Only a relatively small number of time switch programs, which are predefined in line with the real requirements in practice, have to be made available; simple light signals are sufficient for the current status display. A switch can be selected between these predetermined follow-up programs, which can be grouped for easy orientation with a usual symbolic representation of the on and off switching points or switching times given in the selected switching program.
  • a time switch is created that, with minimal circuitry and operating effort, provides an optimally application-oriented function with regard to operational readiness and the choice between predefined switching programs with constant, timely operational readiness, for example to switch over the operating point of heating or cooling units or such units to be used in time-dependent start-stop operation.
  • any other can also be used in addition to the temperature control Electrically switchable consumers are operated, such as for arming terrain or building monitoring and security devices depending on the time of day, or for operating lighting systems depending on the time of day.
  • the timer 31 shown has in the usual way an internally self-sufficient, preferably quartz-stabilized, clock generator 33 operated from a network 30 or from a buffer battery 32 as a time-keeping circuit.
  • This delivers counting pulses 34 with a fixed repetition frequency to a decoding register 35, which can be designed in the usual way as a series connection of counting stages or, with a suitable input pulse frequency, directly as a shift register.
  • the individual register outputs 36 switch at an assigned one Number of input counts 34 temporarily to a defined signal level (such as high signal). Certain outputs 36 are wired for level interrogation and run on their own program switch 37. Using its handle 38, a manual selection between the different, predetermined switching point sequences is possible in order to deliver corresponding control signals 39, for example, to the load controller 40 of a device 41 fed from the stationary power supply network 30.
  • the battery 32 for the timed operation of the switching device 31 is dimensioned for long-term supply in the order of at least 10 years, for which purpose a commercially available lithium battery 32 is preferably used.
  • the switching device 31 is started by the manufacturer after the production and functional final check by inserting this long-term battery 32.
  • register 35 is e.g. Via an adjustment input 42 which is externally accessible in the course of the output test, set to the currently given point in time, for example by feeding in a higher-frequency sequence of correction pulses 43 for counting up the register 35 from its production-related zero position to the currently given point in time.
  • a synchronizing switch 48 can also be provided, which, operated about once every few years by the operating service at a specific hour of the day (around 9:00 a.m.), adjusts the time-dependent switching sequence control to this predefined daily time value by a simple button press, in order to make it less expensive To be able to use timed clocks 33, which could otherwise lead to too great a time deviation over the years.
  • a calendar 45 downstream of the daily transfer 44 of the register 35 in the manner of a programmed read memory can be used for this be provided to output change information 46 at the respectively applicable time in order to take into account the respective time shift of the summer-winter time change in the current register position.
  • Such change information 46 can consist, for example, in the output of correction pulses 43 for advancing register 35 by one hour or by 23 hours in order to take the time shift into account in the daily or weekly cycle of the switching sequences. This ensures that the register outputs 36 can always be tapped over the normal operating time of such a switching device 31 without the need for any operator intervention.
  • the manually operable program switch 37 is provided for the selection of differently specified switching sequence sequences.
  • its control signal transmitters 47 are set (I) or reset (O) at certain points in time or continuously on signal output.
  • the control signal transmitter 47 is set from 6 a.m. to 9 p.m. in the uppermost switch position (e.g. to be selected from Sunday to Thursday), but on Friday and Saturday in the next lower switch position from 8 a.m. to 11 p.m.
  • the control signal 39 (for example high pontential again) is output via the changeover switch 37.
  • an additional decoding query of the daily transmissions 44 can also be used to encode the switching positions on a weekly basis.
  • the control signal 39 which appears as a function of time and switch position, causes the load control 40, for example a contactor, to switch on and off or switch over the operation of the consumer 41.
  • This is, for example, a fluid circulation unit for ventilation or Tempering objects or rooms.
  • the so-called consumer 41 here can also be a thermostat that switches on by means of the control signal 39 different target temperatures is set.
  • the function of the switch 37 can be used, for example, to let the room temperature drop lower on Fridays and Saturdays later (at 11 p.m.) than after the weekend (on Sundays to Thursdays at 9 p.m.); while, for example, an additional daily carry-out query of the time decoding register 35 by means of the control signal generator 47 can trigger a later temperature rise on Fridays and Saturdays than on the other days of the week. If the specified time switching points are currently unsatisfactory, the time-dependent control can be replaced by selecting one of the two switching positions shown below.
