Definitions

  • the invention relates to a device for monitoring an electronic control device for a printing press with assemblies connected by means of a bus system, at least one memory, at least one input and output unit and at least one display device.
  • control of printing presses with the aid of digital control devices often also includes functions in which errors can lead to considerable material damage or even endanger people. Particularly in the case of complex structures of control devices, very high demands are therefore also placed on the reliability of individual system components.
  • EP-A-0 243 661 describes a printing press with a number of measuring devices, sensors generating electronic signals, electronically controllable actuators, units and at least one control and monitoring desk for monitoring, controlling and regulating the entire printing process.
  • This application includes central overall electronics which controls and monitors the entire processing of all sensor signals and the entire coordination of the actuating signals by means of a data processing and control device.
  • two processors are provided for testing and monitoring, which, in addition to the modules assigned to them, also test and monitor the other processor and means for communication between the processors.
  • test results - are referred to below as error messages in the event of errors.
  • non-volatile storage is provided in order to be able to evaluate important data even after the printing machine or the control device has been switched off.
  • error messages, Test results or operating parameters can be saved.
  • the data can preferably be stored in such a way that the most recent data is in a non-volatile memory.
  • each computer 1, 2 has a (micro) processor 3, 4 and further assemblies, such as, for example, main memory, program memory and internal bus system, the explanation of which is, however, not necessary to understand the present invention.
  • error messages can also be evaluated when the corresponding card is removed from the control device and is, for example, for repair purposes at the manufacturer or a maintenance facility.
  • a central display unit 11 is connected to the computer 1 via a serial interface 12 to display the data occurring during the operation of the printing press.
  • the interface 12 and the display unit 11 are also used to display error messages.
  • Additional display units 13, 14 are connected to the input / output unit 8 via serial interfaces 15, 16 and also serve to display error messages in addition to displaying operational data.
  • the computer 2 for controlling the main drive is connected to a control card 17 for the main drive, to which the motor 19 of the main drive is connected via a power stage 18.
  • the control card 17 also has a connection to the system bus 7 so that, for example, the computer 1 can query the state of the power control card 17.
  • a plurality of power supply units are provided for the voltage supply of the digital control device, of which only two power supply units are shown as examples in FIG. 1. For security reasons, it is provided that the computer 1 and the central display unit 11 are connected to a first power supply unit 20 and the computer 2, the input / output unit 8 and the further display units 13, 14 are connected to a second power supply unit 21.
  • the computer 1 By using a connection between the computer 1 and the central display unit 11 that is independent of the system bus 7 and by using a separate power supply unit 20 for these modules, it is also possible to display errors that prevent data flows to one of the display units or on the system bus.
  • Programs are provided for the microprocessors 3, 4, which enable extensive tests and monitoring.
  • the other microprocessor and the communication memory 9 are monitored by each microprocessor.
  • the test and monitoring programs can be designed so flexibly that more or fewer tests are carried out depending on the respective test results. For example, in normal operation it can be provided that each of the microprocessors 3, 4 tests the other microprocessor except for a part of the modules of the control device. However, if the other microprocessor fails, the still functional microprocessor also tests the modules previously tested by the other microprocessor.
  • FIG. 2 shows essential parts of a test program which runs in the microprocessors 3, 4 after the control device has been switched on. After starting at 31, a self-test 32 is carried out, which is carried out by the respective microprocessor and relates to the respective computer 1, 2. In the event of an error, a corresponding error message is stored at 33 and fed to the central display unit 11 (FIG. 1) at 34 via the serial interface 12.
  • the communication memory 9 is tested in the program part 35. This is done in a manner known per se by registering and reading out information again. In the event of an error, storage and display take place again, while if the communication memory 9 is free of errors, the other microprocessor is tested in program part 36.
  • test program is ended at 38, after which programs for activating the printing press are activated. This can also be done in accordance with the program parts store 33 and display 34 if no errors have been found beforehand which prevent proper operation of the printing press.
