  • the sequence control ASE, real-time clock EU and the element HE which characterizes the hardware operating state of the control module STB are advantageously implemented in an application-specific integrated circuit ASIC — “Application Specific Integrated Circuit”.
  • a control unit STL necessary for controlling the method according to the invention is additionally implemented in this.
  • a volatile memory DRAM is arranged as a working memory in the control module STB, to which all currently running programs in the control module STB access technical processes and thus contains the current data of the running processes or current configuration data.

  • the first threshold value decider SWE1 to the control unit STL implemented in the application-specific integrated circuit ASIC by generating and transmitting a first threshold value signal swsl.
  • the control unit STL is designed in such a way that when the first threshold value signal swsl is received, all the program-related processes currently running in the control module STB and the processor accesses executed by them - for example to the volatile memory DRAM - are completed according to the process, and thus all about the failure of the operating voltage BS data to be backed up - in particular the register data of the individual program-related processes active in the volatile memory DRAM when the operating voltage fails - are updated and thus represent a stable, program-related state of the control module STB.

  • the two voltage threshold values U1, U2 are advantageously set such that, in the present case of the control module STB, the period from the failure of the primary voltage source - BS or VS ⁇ Ul - until the supply voltage VS supplied by the substitute voltage source EQ falls below the second voltage Swell value U2 - VS ⁇ U2 - is sufficient for a correct reading of the data stored in the volatile memory DRAM and thus the control module STB or a communication system integrating the control module STL can continue to be operated without loss of data in normal operation after reactivation of the primary voltage source or operating voltage BS.
  • the third threshold value decision maker SWE3 If the level of the supply voltage VS supplied by the replacement voltage source EQ falls below the predetermined third voltage threshold value U3 - VS ⁇ U3 -, this is reported by the third threshold value decision maker SWE3 by generating and transmitting a third threshold value signal sws3 to the control unit STL.
  • the control unit STL deactivates all dynamic, high-priority functions that are still running in the application-specific integrated circuit ASIC.
  • the energy requirement EPA of the application-specific integrated circuit ASIC is further reduced considerably, since the integrated circuit ASIC implemented in CMOS technology has a very low current consumption or energy consumption in static operation.

Abstract

L'invention concerne un procédé selon lequel en cas de panne de la tension de service (BS) fournie par une source de tension primaire dans une circuiterie (STB) commandée par programme, cette dernière est alimentée en tension d'alimentation (VS) par une source de tension de remplacement (EQ) à réserve d'énergie limitée. En fonction de l'intensité de la tension d'alimentation (VS), au moins une fonction partielle des fonctions accomplies dans la circuiterie (STB) est désactivée en fonction de son importance et/ou de sa consommation en énergie spécifique à son déroulement, la réserve d'énergie de la source de tension de remplacement (EQ) étant utilisée de manière optimale en considération de la fonctionnalité globale.
