Definitions

  • the invention relates to a time switch with a time display device for minutes and hours and with program switches, which are arranged according to successive time segments of a time range, in particular a day, and can be mechanically brought into an exhibition or an exhibition, and the program switch, which is assigned to the time segment in which the time displayed is located, its position is scanned and an output signal is output accordingly.
  • Such a multiple-appointment switching device is known from DE 29 04 744 C2.
  • an arrangement of sector-shaped program sliders, each of which can be moved into one of two positions, is clearly arranged around a clock face, which correspondingly bring the associated program switch contacts into an off or on position.
  • These switch contacts are scanned by a query contact which rotates synchronously with the hour hand and which accordingly outputs an output signal to a signal device when the switch contact is in the switched-on position.
  • This switching device is therefore not suitable as a time switch.
  • there is constant contact wear at the Scanning on, and the motor drive of the scanning contact requires relatively high electrical power.
  • a time switch is known from DE 20 41 356 A1, which is equipped with sectorally arranged 2-position slides.
  • an interrogation contact rotates driven by the clockwork, which bridges in the areas of ring-shaped contact paths in which one of the 2-position slides is in the setting, i.e. it projects into the interrogation contact orbit.
  • This gives rise to an output signal on the contact tracks, which is only loaded with a relay to protect the contact tracks during sliding contact while the clockwork continues to run, the contact connections of which are freely usable to the outside.
  • there is only a low switching voltage and switching power at the contact arrangement the contact tracks of which are produced in a rational manner as a printed circuit.
  • the advantage of the mechanical-electrical time switch is a simple program entry and a clear program display; Disadvantages are the presence of a gearbox that is subject to wear and the rotating switching disk, as well as the resulting relatively high power requirement, which requires special precautions to keep the time and restore the timely mechanical query during or after a power failure.
  • an electronic digital clock control circuit supplies the specified time segments with interrogation signals to the program switches, the programmed mechanical positions of which are electrically closed or opened in accordance with their programmed mechanical positions and, if appropriate, via decoupling elements in a space and / or time division multiplex circuit, in particular . are linked in a shift register circuit, which either outputs the output signal directly on the output side or is connected on the input side to the clock control circuit which, in accordance with the program, determines and outputs the output signal from the respective multiplexer signals, which controls a relay with an output contact, the connections of which are freely accessible.
  • the program switch contacts are only subjected to low-power electronic signals, and the contacts are only mechanically actuated during a programming process which is generally very rare. Since the program switches remain in fixed positions even during ongoing operation, the program reading and setting is much easier than in the case of clocks in which the setting device continuously rotates with the time during the later query.
  • the current time is expediently shown on a digital display in a known manner, and a weekday display is also provided, since it is advantageously possible to convert a day timer to a week timer by exchanging the scales and operating a switch with little effort.
  • a quasi-analog sector display can also be attached within the switch arrangement arranged in a circle, with the program, i.e. the switches actuated during programming are displayed and secondly the current time sector is to be identified by a flashing control.
  • An analog clock can also be used to display the time, since it is independent of the program query.
  • the arrangement of the program switches is preferably on provided a circle; however, a matrix arrangement of the switches or buttons can also be selected.
  • the program switch contacts can be queried expediently via a matrix circuit, in the link branches of which there is a resistor with a program contact or a diode with a program contact.
  • the rows of the matrix are each individually supplied with an interrogation signal, and the column lines are connected to interrogation inputs of the electronic control circuit. In this way, all contact states can be determined by a corresponding time multiplex query.
  • the external circuit is simplified if only one column or row of the interrogation circuit is provided, since then decoupling elements are eliminated externally.
  • the decoupling is achieved internally in the control circuit via a correspondingly large output or input multiplexer.
  • Another type of query is a very simple arrangement of a shift register, the Set inputs are connected to the individual program switches, which are controlled by a corresponding set signal, and a pulse chain of shift signals, which occur at the respective time sections, acts on the shift register, so that the current switch signal is immediately present at the output thereof, which is used to actuate the Relay with the externally led switching contact is used.
  • An advantageous embodiment of the time switch is equipped with at least one switch-on timer which controls the switch relay at the beginning of a time segment for a predefinable time in which a program switch is switched on.
  • a relay controlled in this way is suitable for an exchange circuit, in which the compressor is switched off and a defrost heater is switched on at the selected times.
  • a second switch-on timer with a second switching relay is provided, which switches off the cooling system fan for the specified time, which is longer than the defrosting time, so that the cooler has already cooled down again, at the programmed times.
  • FIG. 1 shows a block diagram with the clock control circuit (CLC), which contains a microprogram control.
  • the circuit is powered from the network (N) with a capacitor-buffered power supply (NT).
  • An electronic quartz control circuit (Q) is provided as the time standard.
  • the clock control circuit (CLC) controls a time-hour and minute display (DA) with digitally controllable sectors of known type and, if applicable, a weekday display (WA) with 7 display sections according to the current time.
  • DA time-hour and minute display
  • WA weekday display
  • ST adjusting keys
  • the arrangement on the input side has a switch for manual and program operation. In manual mode, the permanent switch on or switch off is one of each select a total of three switch positions.
  • a changeover switch (US) is provided on the input side, which serves to reverse the switching between daytime and weekly operation and can be reversed with the scale carrier.
  • a relay On the output side, a relay (LR) is connected to the clock control circuit (CLC), the relay contact (AS) of which is led outside for any use.
  • the relay (LR) can be a conventional electromechanical relay, a pulse relay or an electronic relay of a known type.
  • the contact matrix is only shown partially. N columns and M rows are provided, and the corresponding switching elements are provided with the relevant indices of the reference numbers.
  • the clock control circuit (CLC) accordingly has M output lines as query lines (A0 - AM), each of which is connected on the one hand to a diode (D00 - D0N; - DMN), each in series with one of the program switch contacts (S00 - S0N; - SMN ) is connected, which in turn are connected in columns to the other contact side.
  • the column lines (E0 - EN) are connected to corresponding inputs of the clock control circuit (CLC).
  • the query lines are acted upon individually according to the current time and the output signals on the input lines (E0 - EN) are evaluated one after the other. If the contact queried is closed, the switching relay (LR) is activated. In addition, a signal display can be controlled in parallel to the switching relay.
  • the switching relay (LR) and preferably a second switching relay (LR2) are only switched on for a predeterminable period from the times in which the time periods begin, their program switches (SOO - SMN) are switched on.
  • the switch-on times of the relays (LR, LR2) are contained in the associated switch-on time memories (T1, T2) and are compared in comparators (V1, V2) with the content of a time counter (T), the content of which is zero at the beginning of a programmed period .
  • T time counter
  • the associated relays (LR, LR2) are switched on.
  • the normally closed contact of the relay contact (AS) switches off the compressor (KP) and the normally open contact switches on the defrost heater (AH).
  • the normally closed contact of the second switching relay (LR2) switches the radiator fan (KL) during the i.a. longer specified second switching time.
  • the switch-on time memories (T1, T2) are counted up or down each time one of the control buttons (ST +, ST-) is pressed, with the counter reading on the time display (DA ) is displayed, which is caused by a corresponding switchover of the counter outputs with the selector switch position signals (I, II).
  • the time of day counter is only switched to the display (DA) when the selector switch (SW) is in the basic position.
  • Figure 2 shows a circular arrangement of the sector-shaped program switch elements.
  • a ring-shaped arrangement of display sectors can be arranged within the arrangement of the 96 keys, each of which is to be controlled in accordance with the setting of the switches or a previous key programming and / or for displaying the current time.

  • FIG. 4 schematically shows a matrix control of the program switches (S00 - SMN) by means of resistors (R00 - RMN) which are in series with the program control contacts.
  • the column lines (E0 - EN) of the matrix are routed to amplifiers whose output signals are routed to the inputs of the clock control circuit (CLC).
  • the output signal is amplified at least 7 times advantageously provided in a switching amplifier, so that even in the worst case, the full signal occurs on the output side.
