Definitions
- the invention relates to a controller for a relay.
- Each computer is e.g. when Microprocessor or microcontroller running. Calculate the calculator, that you should switch their respective relay, they give appropriate Control signals to their outputs. If both control signals are present, then Both relays switch and the total contact is closed.
- Fig. 1 shows the principle of a dynamic control.
- Channel 1 of a first computer ⁇ C1 is given to a first control circuit.
- the first Control circuit includes a capacitor C1, two diodes D1, D2 and a switching contact K1, which are interconnected.
- Capacitor C1 and Diode D2 are connected in series and are in the longitudinal branch.
- Diode D1 is connected to capacitor C1 and diode D2 and is located in a first transverse branch.
- Switching contact K1 is connected to diode D2 connected and is located in a second transverse branch.
- Switch contact K1 controls a first switch S1 connected in series with a second switch S2 is switched.
- Channel 2 of a second computer ⁇ C2 is set to a second Control circuit given.
- the second control circuit includes a Capacitor C2, two diodes D3, D4 and a switching contact K2, the interconnected with each other.
- Capacitor C2 and diode D4 are in Row switched and are in the longitudinal branch.
- Diode D3 is with Capacitor C2 and diode D4 connected and is located in one first transverse branch.
- Switching contact K2 is connected to diode D4 and is located in a second transverse branch. Switch contact K2 controls the second switch S2.
- switch contacts K1 and K2 close the switches S1 and S2 only after receiving a continuous 0/1 sequence and keep the switches S1 and S2 also continue only closed as long as the continuous 0/1 episode, the one Clock signal with a logic zero at 0 volts and a logic one at 5 Volt corresponds, is received.
- the object of the invention is to provide a control for a relay, the a signal technically safer control allows.
- a signaling technology safer control is by a coded Control and monitoring of the control achieved. Either Hardware and software errors can be reliably detected by signal technology become.
- Fig. 2 shows the principle of an inventive control of a relay.
- the structure of the controller is substantially similar to the structure of FIG. 1.
- Resistor R1 is connected to computer ⁇ C1, computer ⁇ C2 and Connected capacitor C2 and serves the feedback of the Control signal of the computer ⁇ C2 on the computer ⁇ C1 purpose Monitoring and evaluation.
- Resistor R2 is connected to computer ⁇ C1, Computer ⁇ C2 and capacitor C1 connected and used for feedback the control signal of the computer ⁇ C1 on the computer ⁇ C2 purpose Monitoring and evaluation.
- the control signals are coded 0/1 sequences.
- the coding takes place e.g. by using a CRC code or such that in one continuous 0/1 sequence, a gap is deliberately inserted, e.g. by Omit certain ones or such that the number of ones is deliberately increased;
- the feedback can be a channel determine whether in the other channel as a control signal a coded or a continuous 0/1 sequence is used as the control signal. Becomes found that a coded 0/1 episode is sent out, sends the other channel correctly. As a consequence, e.g. also a correct, encoded 0/1 episode sent out.
- a failure or malfunction of a computer are thus in the current Operation recognizable, creating a signaling safer control is reached.
- a Safety reaction The relay in the still functioning other channel will be switched off.
- the contact sets are connected in series, so that As a result, the signal-technically secure overall contact is switched off.
- Fig. 2 shows a section with two computers.
- three Calculator used. For a two out of three decision, each one receives three computers the feedback signals of the other two Computer. The calculator will then, according to the two out of two Arrangement of Fig. 2, turn off its own relay, as soon as he no receives correctly coded signal from one of the two neighboring computers. All Calculators work e.g. with the same coding known to all computers is.
