  • the Comparator in the respective local transmission unit Difference value between the local measurement signal and the reference value switches those downstream of the comparator Trigger means by (i.e. binary signal value "1"), or disable (i.e. Binary signal value "0").
  • comparator and trigger means The digitalization of the analog measurement signals, for example, has been proven especially with regard to the speed and safety of the Data transmission as extremely advantageous, not least because digital Data transmission the susceptibility to faults and the frequency of errors is much lower than in the transmission of analog signals.
  • the Transmission means of the local transmission units to a multiplex transmitter transmits.
  • the receiving means of Central processing unit a multi-channel multiplex receiver, at least two counters and an evaluation circuit, with one counter each one local Transmission unit is assigned. This arrangement is an optimal Possible application for the multiplex method, because the sequence of individual pulse trains a simultaneous and error-free transmission of the local Measurement signals of all local transmission units connected to the central unit guaranteed in the shortest possible time.
  • Each of these n local transmission units 2 is supplied with a local, for example analog measurement signal UM 1 , UM 2 , ..., UM n .
  • the multiplex two-wire line 3 consists of two wires; For reasons of simplicity and clarity, the multiplex two-wire line 3 is thus identified by a line in FIGS. 1 to 9.
  • FIG. 2 shows a section of a block diagram of an inventive electrical circuitry.
  • the central unit 1 and one of several local transmission units 2 through the multiplex two-wire line 3 are connected.
  • the central unit 1 has a multiplex channel generator 4 on.

  • the multiplex channel generator 4 arranged in the central unit 1 generates in periodic time intervals a pulse train 15 shown in Figure 3.
  • This pulse train 15 is composed of a synchronization pulse 16 and a sequence of at least two channel pulses 17a, 17b, ..., of which the one shown here Embodiment each a channel pulse 17a, 17b, ... one each of the Central unit 1 is assigned to connected local transmission units 2.
  • the immediately successive pulse trains 15 are transmitted via the multiplex two-wire line 3 to the individual local transmission units 2.

  • the counter 10 sends to the digital / analog (D / A) converter 11 a digital signal which corresponds to a sequence of the bit sequences assigned to the decimal numbers 0 to 7.
  • the D / A converter 11 converts this digital signal into a corresponding analog signal, which is referred to as the reference value UR.
  • the difference value UD k between the, for example analog measurement signal UM k supplied to the local transmission unit 2 and the reference value UR is determined, the index k denoting the kth local transmission unit 2.
  • a trigger 13 downstream of the comparator 12 switches through, which corresponds to a binary signal value "1"
  • the trigger 13 for a non-positive difference value UD k ⁇ 0 disables (binary signal value "0").
  • the trigger 13 therefore serves to digitize the analog difference value UD k , each of the binary signals generated in it being transmitted as a channel pulse from the multiplex transmitter 14 on the channel A k to the multiplex receiver 5 arranged in the central unit 1.
  • This multiplex receiver 5 is set up for multi-channel operation, since it successively picks up the respective binary signal from all n local transmission units 2 as a channel pulse.

  • the further evaluation of the respective binary signal is then carried out separately, ie channel-specifically in the counters 6, which are assigned to the evaluation unit 7. If necessary, the evaluation unit 7 is also followed by the display unit 8, which displays the data evaluated by means of counter 6 and evaluation unit 7 in a suitable form.
  • FIG. 4 shows an exemplary embodiment for the multiplex channel generator 4, an input stage 41, a trigger 42, a clock 43, an output stage 44, a pulse generator 45 and an encoding module 46.
  • the multiplex channel generator 4 belongs here to a digital pulse code on the Multiplex two-wire line 3 impress and so the entire electrical Circuit arrangement by clocking each individual module of the electrical Control circuit arrangement.
  • the multiplex channel generator 4 is used but also as a power supply for the multiplex transmitter 14, if this is not its own Power supply should have.
  • the multiplex channel generator 4 for the Generation of, for example, 8, 16, 32, 64 or 128 channels can be encoded.
  • the Input stage 41 detects whether the channel whose time window is currently open is activated by the multiplex transmitter 14. If this is the case, it changes Signal of the trigger 42 to the pulse generator 45, the pulse shape for the concerned, d. H. the activated channel.
  • the voltage signals are transmitted in a multiplex two-wire process with typical frequencies of the order of 1 kilohertz.
  • the pulse generator 45 generates pulse trains shown as examples in FIG 15, which are synchronized by means of the clock 43.
  • the number of with these Pulse trains 15 channels to be transmitted are, as mentioned above, determined by the coding module 46.
  • the output stage 44 which amplifies the signal and on the multiplex two-channel line 3 outputs, must be protected against short circuit, since the multiplex transmitter 14th the entire multiplex two-wire transmission system for a period of time that is in is about a sixth to a quarter of the time length of a channel pulse, shorts to indicate that input stage 144 of the one shown in FIG Multiplex transmitter 14 shown is activated.
  • FIG. 6 shows an embodiment for the multiplex transmitter 14, the an "AND" gate 141 with two inputs, a comparator 142, one Counter 143, an input stage 144, a coding module 145, a reset 146 and an input terminal 147, the comparator 142, the counter 143 and the coding module 145 are taken together as decoding means can.
  • the principle of operation of the multiplex transmitter 14, which is connected in parallel in the multiplex two-wire arrangement, is based on the fact that, when the input stage 144 is detected as open, ie activated, or closed, the multiplex transmitter 14 sends a signal to the multiplex channel generator 4, which in turn changes its pulse code from "0" to "1". This is done in the following ways:
  • the input stage 144 of the multiplex transmitter 14 is coded for a specific channel pulse by means of the coding module 145.
  • the counter 143 is used to monitor the digital pulses which are output by the multiplex channel generator 4, the counter 143 being reset by the reset device 146 as soon as the synchronization pulse 16 is detected.
  • the channel 142 for which the multiplex transmitter 14 is coded is compared by means of the comparator 142 with the stored number of channel pulses 17a, 17b,... If these two parameters are of equal size, the comparator 142 sends a signal to one of the two inputs of the "AND" gate circuit 141.
  • the other input of this "AND" gate circuit 141 is connected directly to the input stage 144 of the multiplex transmitter 14.
  • both inputs of the "AND” gate circuit 141 are activated, ie the output of the "AND” gate circuit 141 is at "high", the multiplex transmitter 14 closes for a period of time which is approximately one sixth to one quarter of the length of time of a channel pulse, the entire multiplex two-wire transmission system is short, whereupon the multiplex channel generator 4 is caused to change its pulse code during the encoded pulse time, this change being shown by way of example in FIG. If the input of the "AND” gate circuit 141 directly connected to the input stage 144 is not activated when its pulse code is reached, ie the output of the "AND” gate circuit 141 is at "low”, the output goes into a waiting cycle until the The next time input port 147 reaches its matching pulse code.
  • FIG. 7 shows an exemplary embodiment for a multiplex receiver 5, the one Detector 51, a comparator 52, a counter 53, an output stage 54 Encoding module 55, a reset 56 and an output terminal 57, wherein the comparator 52, the counter 53 and the coding module 55 together as Decoding means can be understood.
  • DIP dual-in-line
  • Figures 8 and 9 show two ways of connecting between the counter 10 and the D / A converter 11 in a local Transmission unit 2.
  • Figure 8 as well as in Figure 9 are each Exemplary embodiments are presented in which the counter 10 and the D / A converter 11 are connected by an 8-bit line.

  • the right column of this table shows a stochastic fluctuation of the signal arriving at the input terminal of the D / A converter 11, so that the D / A converter 11 output analog reference signal UR no continuous, for example, has a monotonously increasing shape, but rather as desired arbitrarily, stochastically evenly fluctuates.
