Definitions

  • the invention relates to a device for arbitrary electrical action on magnetic items, in particular switches of a model railroad system, with a central control unit for generating control signals that can be transmitted via lines to the magnetic items, with one group of magnetic items each being connected to a receiver that can be coded by an address switch is, the receivers are connected to the central control unit via a ring line with a number of lines independent of the number of solenoid accessories, and wherein the central control unit is set up to deliver digital data telegrams as control signals to the ring line, of which a data telegram each contains address data for Addressing one of the Manget redesign and command data to act on the addressed solenoid, as well as with a status memory for storing the status of the individual solenoid and with control means for status display of the Magnetar article.
  • Such a device is known from DE-A 24 33 025, the solenoid items being controlled by a program control unit in a time-programmed manner. Individual control and a status display on call is not possible.
  • a manually operated switch button is available for each switching device.
  • a bus line extends from the control unit, to which receivers for controlling the switching devices are connected, with each switching device being assigned a receiver.
  • the object of the present invention is therefore to develop a device of the type mentioned at the outset in such a way that systems with magnetic articles can be set up flexibly with little wiring effort and without special knowledge and are nevertheless less susceptible to malfunction during operation.
  • the device is also intended to provide a prerequisite for the fact that the operating processes of the system can be easily adjusted.
  • ten receivers can be controlled using only one central control unit with, for example, ten address keys via a ring line with only a few wires.
  • Each receiver can in turn apply electricity to ten magnetic items according to the control. Only the lines between the magnetic articles and the receivers are, for example, three-wire. Since one receiver can be placed in the center of several neighboring solenoids, the total required cable lengths can be kept short.
  • the control or action on the solenoid takes place in such a way that two-digit numbers are specified with the address keys, of which the first digit identifies the recipient who evaluates the data telegram for the solenoid, while the second digit indicates the individual solenoid.
  • the data telegram generated by the central control unit thus contains a two-digit address in the decimal system, followed by a status date - for example, setting the switch to the right or to the left.
  • the signals are binary coded in the data telegram.
  • One receiver each is coded by setting its address switch in order to be assigned to the first decimal digit of the address.
  • the assignment of the second decimal digit to each address is done by connecting the solenoids to the output terminals of the receiver.
  • the result of this is that not only is the cabling or wiring effort for this device low, but also that only a few address keys are required to control a large number of magnetic articles.
  • the device can be used flexibly, since laypersons can also assign the addresses to the addresses by setting the address switches of the receivers with which they are encoded. Since the central control unit emits a binary-coded digital data telegram to control each solenoid, the reliability of the device can be assumed to be high. In particular, fluctuations in the signal strength of the data telegram, in particular due to contamination of contacts, can be tolerated to a large extent without faulty controls.
  • each controlled solenoid is still displayed after pressing the address keys in the address display means, for example as a two-digit decimal number.
  • the status of the addressed magnetic article is checked by the status display means, for example a red or green lamp, depending on whether a turnout is set to the left or to the right. If the appearing status of the solenoid does not correspond to the operator's ideas, the operator simply presses a status key for the desired status, which then transmits the data telegram with the solenoid selected address and the corresponding status command.
  • This obvious operation makes the device appear particularly suitable for upscale gaming purposes, all the more so since the effort for production is low, especially in the simplifying training given below.
  • Certain combinations of status states of the individual magnetic articles can be stored in the central control unit by the configuration of the device according to claim 3 and can be output by pressing only a few keys.
  • Various combinations of the positions or states of the individual magnetic articles can thus be conveniently and quickly set, for example for forming so-called routes in model railroad systems, after these data have been entered into the central control unit. This can be done in such a way that the display of the address display means and the status display means initially disappears by pressing the memory key. After pressing an address key, the address assigned to a specific route appears as a decimal number in the address display. If you then press the enter button, the turnouts or signal positions of the solenoid accessories are transferred to the additional memory after the address buttons and status buttons have been pressed.
  • the device After completion, the device automatically goes into the manual input mode that was described in connection with claims 1 and 2.
  • To call up a status sequence for forming a route first the memory key is pressed and then the address key which identifies the status sequence. Then the data telegrams are formed by pressing the call button and fed into the ring line, which act on the solenoid after decoding.
  • the ring line of the device according to claim 4 preferably has four wires.
  • the clock pulses generated by a clock generator in the microprocessor of the central control unit, which are passed to the receivers via a core of the ring line, are used for
  • the receivers are expediently constructed according to claim 5 as intelligent decoders with the adjustable address switch.
  • the intelligent decoder can expediently be implemented by a microprocessor.
  • the receiver is advantageously set up either to deliver a continuous current, to the solenoid addressed with a data telegram, or to generate a current pulse.
  • receiver to be adapted to the various articles in a variety of ways, for example on switches which can be actuated dynamically by pressure surges.
  • the arrangement of a matrix circuit between the outputs of the decoder and the magnetic articles will reduce the number of output stages required to adapt to the power requirements of the articles and the drivers connected upstream of them. For example, only four output stages in four rows and five output stages in five rows of the matrix circuit are required, that is to say only nine output stages and associated drivers, in order to optionally control ten outputs for magnetic articles, each with three lines in one direction or the other.
  • the address display means are advantageously designed according to claim 9 with seven-segment display elements.
  • Colored illuminated buttons are particularly suitable as status display means and can also be used to issue a status command.
  • a red and a green light button are used to display and display a straight setting of a switch or a curve setting.
  • 1 denotes a central control unit which is connected to a power supply unit 2.
  • a ring line 3 leads to several receivers, of which two receivers 4 and 5 are shown. Ten three-wire lines go out from each receiver, which are designated to the receiver 4 by 7-16.
  • a switch 6 is connected to the line 15 and can be switched over by two magnets, not shown. The switch is a magnetic article.
  • the entire facility is part of a model railway.
  • the core of the central control unit is a microprocessor 32 which is connected to a sixteen-key unit 33 via a four by four matrix.
  • the sixteen-key unit combines the address key 18 and the keys 22 to 25 provided for storing the status sequences.
  • An operating DC voltage from the power supply unit 36 is connected to a line 34 via the terminal 35.
  • two accumulators 37 are connected to the line 34 and prevent the memory from being erased when the operating voltage is switched off.
  • the microprocessor 32 controls two seven-segment display elements 39 and 39a of the address display means via a display decoder 38.
  • an additional memory 40 can be seen in FIG. 2, which is designed as a RAM memory and is used for storing status sequences.
  • FIG. 3 schematically shows the structure of a receiver with an intelligent decoder 41.
  • the decoder can be connected to the ring line via input terminals 42 to 45.
  • the operating voltage is smoothed by capacitors 46 and 47 and a stabilizer 48 and fed to a terminal V CC of the intelligent decoder.
  • a terminal RESET of the decoder is connected to the terminal V ce via a diode 49 and a resistor 50 and, on the other hand, is led to zero potential via a capacitor 51.
  • a terminal C ki of the decoder is connected to the terminal V ce via a further resistor 52 and is connected to earth potential via a capacitor 53.
  • FIG. 4 shows the output terminals 71 to 79 of the decoder, to which a four by five matrix circuit with driver stages 81 to 89 and output stages 91 to 99 are connected.
  • the collectors of the transistor transistors lead to ten three-pole outputs 01 to 010 for the magnetic articles.
  • the collectors are decoupled via diodes 100 to 108.
  • the microprocessor 32 controls all functions in the central control unit. Only eight lines 33a are routed between the key unit 33 and the microprocessor, since the key unit is connected in a four by four matrix.
  • the additional memory 40 which is designed as a RAM memory, is used in the manner already generally described for storing and outputting the status sequences which can be read in after actuation of the memory key 24 and the input key 23, for example to form a route with the magnetic articles.
  • the input is otherwise similar to the manual input using the address keys 18 and the command keys 20 and 21 in FIG. 1.
  • the display decoder 38 via which the microprocessor is connected to the seven-segment display elements 39, 39a of the address display means 17 , has a usual structure and mode of operation.
  • the adjustable address switch 63 of each receiver the decade of the addresses is set which are to have an effect on the articles connected to the receiver. For example, when the address switch is set to the first level, it is the first ten digits in decimal counting. Accordingly, at one of the first ten addresses, a signal will appear on the output terminal of terminals 71 to 79 corresponding to the address, depending on the position of the switch 68 as a permanent static signal or as a dynamic pulse, in order to refer to the associated articles in the act as desired.
  • the driver transistors 81 to 89 and the end transistors 91 to 99 are arranged.
  • the arrangement in the four by five matrix shown in Fig. 4 results in a reduction of the driver and final stage transistors from normally twenty, since there are two ten outputs (each of the ten outputs 01 to 010 is three-pole) to nine here.
  • a signal at the output terminal 71 of the decoder 41 causes the driver transistor 81 to bring the corresponding transistor 91 into conduction, which flows a current in the direction of arrow 109 across the first two terminals of the output 01 and the output stage transistor 95 and through the driver transistor 85 is also open because the driver transistor 85 is also controlled via the output terminal 75.
