Definitions

  • the invention relates to a diagnostic system for a digital control device of a printing press.
  • the 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 control device structures, very high demands are therefore also placed on the reliability of individual system components.
  • the object of the present invention is therefore to provide a diagnostic system for a digital control device of a printing press, which has a reliable detection and Display of errors allowed.
  • errors should also be detectable if possible when a processor performing the monitoring fails.
  • subsequent diagnosis is required.
  • the diagnostic system is characterized in that at least one processor is provided with a program for testing modules of the control device and for monitoring parameters during the operation of the printing press and that results of the tests and the monitoring of the parameters are displayed and / or stored.
  • the processor preferably also performs control tasks.
  • 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.
  • At least one of the processors has an output for error messages bypassing a bus system. It is advantageous that each of the processors is arranged on its own system card and that the processors are independently connected to at least one display device each.
  • 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 stored for this purpose.
  • 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 microprocessor 3, 4 and further assemblies, such as, for example, main memory, program memory and internal bus system, the explanation of which is not necessary for understanding the present invention.
  • non-volatile memories 5, 6 are provided on the computer cards, which store test results, operating data and error messages that are required for later evaluation, in addition to a shutdown or a defect in the control device.
  • error messages that do not lead to a failure of the control device or the computer concerned, several error messages can be stored with other meaningful test results and operating parameters, if necessary.
  • 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.
  • the computers 1, 2 are connected to a system bus 7, which is further connected to an input / output unit 8 and a communication memory 9.
  • the communication memory 9 serves to exchange data between the computers 1, 2 in such a way that the receiving computer in each case retrieves from the communication memory 9 those data which the sending computer has previously written.
  • test results and error messages can also be stored in the communication memory 9, which is then designed as a non-volatile memory. These can then be read out by both computers 1, 2.
  • sensors and actuators are connected to the input / output unit 8 via inputs and outputs, as described, for example, in the applicant's patent application P 36 42 500.1.
  • 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.
  • Several 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.
  • each of the microprocessors 3, 4 tests the other microprocessor apart from 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 is switched on. After a start 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 writing in 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 in itself also be done after the program parts store 33 and display 34, if no errors have been found beforehand which prevent proper operation of the printing press.
