Definitions

  • the invention relates to a time switch according to the preamble of claim 1.
  • Such a time switch is known as an electronic time switch from the Patent Abstracts of Japan, Volume 009, No. 186 (P-377) JP-A 60 056 287.
  • the circuit which contains a non-volatile RAM for its operating program, has a reserve voltage source for the failure of the operating supply. If this also fails, then the operating program must be set to the current time in order to be ready for operation again when it is ready for operation again; but the cited publication does not show how the time reference is obtained and how the time correction is carried out.
  • a consumer watch known in the art as an autonomous radio clock in which the time display itself is operated from an internal time-keeping circuit (such as a quartz oscillator), but with the special feature that from time to time Receiver is switched on, which is tuned to a long-wave transmitter, via which a coded absolute time information is transmitted.
  • the demodulated time information is compared with the currently displayed time and corrected in the event of deviations.
  • the peculiarity of the radio clock described there lies in not letting the time display start at the start of operation, but first connecting one of the pointers in time with the received time telegram pulses in order to indicate whether there is currently undisturbed or disturbed reception.
  • a radio-controlled traffic signal system is not a radio clock in the present sense, in which successively received time information for the phase change is checked on the basis of an expected value in order to avoid incorrect controls.
  • the light signal control there is based on constant radio contact with the timer center for retrieving the control information from a programmable read-only memory.
  • a time switch in the present sense is used for the time-dependent switching on and off of consumers connected to its different switching channels.
  • Such a timer is regularly equipped with a so-called power reserve for bridging temporary failures in the feed network. This ensures that the time switch continues to work at the correct time even during a network failure and thus normal network operation can be continued when the network is available again without having to readjust the time switch to the actually given, current point in time.
  • the power reserve consists of a primary or secondary battery and a voltage-controlled switching device, via which the drive of the switching timer, which normally occurs from the mains, is switched to battery supply when the mains voltage falls below a minimum value required for operation, in particular if the mains due to mains malfunctions completely.
  • Such a time-buffered battery for the power reserve is known, for example, from FUNKSCHAU issue 2/1982 (page 112 bottom left).
  • the operating buffering of the built-in power reserve ensures that the actual switching mechanism is still operated in a time-keeping manner in the event of a power failure, and thus, when the power is available again, the load control is then carried out again at the specified times via the time switch.
  • a disadvantage of equipping a time switch with such a power reserve is, on the one hand, that two drive mechanisms are usually required to enable the time-dependent operation of the time switch either from a network and from a battery (with a regularly lower voltage), or quite right elaborate conversion circuits for the seamless transition of the drive device between different supply sources (see. DE-PS 1921520). And it is particularly problematic when using such a memory-buffered power reserve that the storage element no longer has the necessary capacity for the bridging operation due to signs of aging, if after several years of trouble-free network operation, emergency operation from the power reserve finally becomes necessary.
  • the available storage (especially rechargeable batteries) that are considered for the power reserve have the very serious disadvantage that after a few years of aging they assume an internal short-circuit condition, ie they are no longer available as a bridging source.
  • the short circuit can even lead to the failure of the time switch in spite of the existing or re-existing network.
  • the lifespan of such storage units quickly drops to short remaining periods; on the other hand, low ambient temperatures lead to a greatly reduced capacity of the electrochemical storage.
  • the object of the invention is to create a timer which is operationally resistant to a power failure and which does not require the relatively expensive and comparatively fault-prone memory for the conventional securing of a power reserve.
  • the only figure in the drawing shows in the egg-pole block diagram a time switch with a radio clock operated by the same network for time control of a consumer fed from this network.
  • a consumer 11 for example a heating or lighting device, is to be switched on or off from the network 12 at predetermined times.
  • the consumer 11 is connected to the network via the switching path 13 of a time switch 14.
  • Their electromechanical or electronic time control device 15 can be adjusted via a manually operable non-volatile mechanical or electronic memory 16 (e.g. shift lever according to DE-0S 32 41 533 or EEPROMs) so that the switching path 13 is preferably at predetermined times with respect to the operation of the Timer 14 (that is, primarily not over predetermined time periods regardless of the actual times) is switched on or off.
  • a manually operable non-volatile mechanical or electronic memory 16 e.g. shift lever according to DE-0S 32 41 533 or EEPROMs
  • the time switch 14 is not equipped with a power reserve for bridging temporary or system-related failures of the network 12. If the network 12 fails, the time switch 14 stops. The time-dependent control of the switching path 13 is thus interrupted; but this has no effect because, due to the lack of available energy in the network 12, the network-dependent consumer 11 cannot be operated anyway. The content of the non-volatile memory 16 for the predetermined switching times is retained. In the event of a power failure, or in any case before the switching control is resumed at the right time, a defined switching state is assumed in the output channels for the load control in order to avoid uncontrolled switching operations or undesired high-load conditions when the network is available again.
  • the time-dependent, preset switching states are resumed in the channels. It can be provided to continue working with the interrupted program at the correct time; or the work cycles that failed during the interruption are rescheduled accordingly, for example in order not to miss any cooling phases in refrigeration technology.
  • a radio clock 17 is provided as an adjusting device, from whose reception decoder 18 the time control device 15 is corrected to the current time received by radio.
  • the radio clock 17 does not work autonomously either, so it can also be fed from the central network 12. Because as long as the network 12 has failed (and the radio clock is not operated as well), the consumer 11 cannot be operated anyway, so no switching operations need to be carried out.
  • the radio clock 17 has immediately obtained the absolute time information for correcting the time switch position from the received time telegrams under normal operating conditions.
  • the switch-on control circuit 19 is also designed to check the current time position of the time switch 14 at greater intervals and, if necessary, to correct it if time deviations with regard to the actuation of the switching path 13 should have occurred due to operational faults (without an actual power failure).
