Abstract
A particularly simple and simultaneously fail-safe control system has a control computer for interchanging data with at least one peripheral, and at least one further control computer connected to the first-mentioned control computer via a communication channel. The further control computer is configured to assume at least part of the functionality of the control computer. The control computer is designed, in the event of partial failure thereof, to forward data received by the further control computer via the communication channel to the peripheral and/or to forward data received by the peripheral to the further control computer via the communication channel. There is also provided such a control computer and a method for operating a control system.
Claims14
A control system, comprising:
- a first control computer configured for interchanging data with at least one peripheral;
- at least one second control computer connected to said first control computer via a communication channel, said second control computer being configured to assume at least a part of a functionality of said first control computer;
- said first control computer being configured, in an event of a partial failure thereof, to forward data received from said second control computer via the communication channel to the peripheral and/or to forward data received from the peripheral to said second control computer via the communication channel.
In a control system having a first control computer configured to interchange data with at least one peripheral, and at least one second control computer connected to the first control computer via a communication channel and configured to assume at least a part of a functionality of the first control computer, a control computer for the control system, the first control computer being configured:
- in the event of a partial failure thereof,
- to forward data received from the second control computer via the communication channel to the peripheral;
- and/or
- to forward data received from the peripheral to the second control computer via the communication channel.
A method of operating a railroad protection control system, the method which comprises:
- providing a first control computer of the railroad protection control system configured to interchange data with at least one peripheral of the railroad protection system;
- providing at least one second control computer connected to the first control computer via a communication channel and configured to assume at least a part of a functionality of the first control computer;
- in the event of a partial failure of the first control computer, forwarding with the first control computer data received from the second control computer via the communication channel to the peripheral and/or forwarding data received from the peripheral to the second control computer via the communication channel.
A railroad protection control system, comprising:
- a first control computer configured for interchanging data with at least one peripheral of a railroad protection system selected from the group consisting of an input/output system, a points contact, a signal actuator, a sensor, and a points drive;
- at least one second control computer connected to said first control computer via a communication channel, said second control computer being configured to assume at least a part of a functionality of said first control computer;
- said first control computer being configured, in an event of a partial failure thereof, to forward data received from said second control computer via the communication channel to the peripheral and/or to forward data received from the peripheral to said second control computer via the communication channel.
