Definitions

  • the invention relates to a method for monitoring and for data exchange between an external data carrier unit and at least one stationary computer unit, the stationary computer unit being connected to the external data carrier unit via at least one connection port and a data connection, and an operating program of connection ports present on the stationary computer unit continuously for a data connection to an external data carrier unit, and an operating program for carrying out the method.
  • US 5,758,067 describes an apparatus and a method for the automatic archiving of data from a computer system to a backup system.
  • the disadvantage here is that the backup procedure is controlled via a software menu which must be set accordingly by the operator.
  • the start of archiving is initiated over a previously specified time and can only be varied within the scope of the specification. Furthermore, no recent data can be transferred from the backup system to the computer system.
  • WO 01/27768 discloses a method for automatic backup of a computer with an external hard drive, the hard drive being connected via the PCMCIA port of the computer.
  • the computer's CPU detects the connection of the external hard drive and automatically starts a backup procedure on the external hard drive.
  • the disadvantage here is that the computer's data is saved exclusively on the external hard drive. Data on the external hard drive with a more current date is not transferred to the computer, so that only the current data of the computer is saved on the external hard drive.
  • the backup is started automatically with the connection via the connection port, without the operator being able to start the process himself.
  • a method for reading out memory cards in a host system is known from US Pat. No. 5,887,145.
  • a connection to the host system is established via a so-called mother card, the data to be read out being stored on a daughter card which can be connected to the mother card.
  • the mother card is connected to the host system via an interface and the daughter card can also be connected to the mother card via a second interface. Flash EEPROM chips, storage disks and other additional devices are available as daughter cards.
  • the disadvantage here, however, is that a data transfer is automatically initiated with the plug-in connection of the daughter card with the mother card. The user can only determine the time of the data transfer via the time of the connection between the mother card and the daughter card.
  • the operating program detects the generation of a voltage pulse by a pulse generator connected to the data connection and located on the external data carrier unit, and then further processes initiated the stationary computing unit and the external data carrier unit.
  • a data exchange is additionally initiated via the existing data connection between the data carrier unit and the stationary computer unit.
  • the invention therefore also relates to a corresponding operating program for carrying out such a method.
  • Data exchange in the sense of the invention is any mutual exchange in the form of electronic or electrical information between a computer unit and an external device which is connected to the computer unit.
  • the data are preferably transmitted as data packets.
  • the operating program controls the data exchange in such a way that data exchange and detection of a newly triggered voltage pulse by the pulse generator is simultaneously possible via an existing data connection, the voltage pulse being detected by the operating program between the sequentially transmitted data packets.
  • the data exchange triggered by the detection of the voltage pulse initiates data synchronization of a predetermined storage area on the stationary computer unit and the external data carrier unit.
  • the data connection can be interrupted and the external data carrier unit can be used for data synchronization with a second stationary computer unit.
  • a renewed data exchange with the original computer unit is also possible.
  • the pulse generator is controlled by the operating program in the stationary computer unit as a virtual drive, the virtual drive not being used as a conventional drive is used, but selected communication commands to control the virtual drive are automatically converted by the operating program to monitor a voltage pulse triggered on the pulse generator, whereby the pulse generator as a virtual drive can only be controlled by the operating program and not in the data carrier management of the stationary computer unit is involved. Regardless of the operating system, this ensures a secure execution of the operating program and the monitoring of the external data carrier unit and the external pulse generator can be designed independently of the interface.
  • the operating program is connected to the data carrier communication between the computer unit and the external data carrier unit and permits direct control of the external data carrier unit as an additional drive.
  • the control and monitoring of the pulse generator as a virtual drive is not integrated into the data carrier communication of the stationary computer unit, but is controlled and managed by the operating program.
  • the external data carrier unit is visible and usable as an additional drive.
  • the pulse generator is not visible as a drive and can be used directly by the operator. Use as a pulse generator is only possible via the operating program on the stationary computer unit, the communication commands for controlling the virtual drive being automatically converted into instructions for detecting a voltage pulse to the pulse generator.
  • the external data carrier unit is also integrated as an additional data carrier drive in the data carrier management of the stationary computer unit and can be controlled by the stationary computer unit as an independent drive. This results in the possibility of assigning the external data carrier unit as an additional drive to the stationary computer unit, the monitoring of the pulse generators by the operating program on the stationary computer unit being guaranteed at the same time.
  • This form as an integrated drive of the external data carrier unit in the stationary computer unit has proven to be advantageous, since an interface and computer-independent execution of the operating program is guaranteed here.
  • an integrated pulse generator is attached to the outside of the data carrier unit in the external data carrier unit, this preferably being a question of this is a push button device.
  • other pulse generators such as, for example, touch sensors, switches or pushbuttons of any kind. Pulse triggering via a touch screen or similar display systems is also possible.
  • the data connection is ensured via a data transport cable, the operating program monitoring the connection port for a data connection and, in the case of a data connection with the external data carrier unit, monitoring the pulse generator via the data transport cable. In the event of a detected voltage pulse by the pulse generator, the operating program initiates a data exchange via the existing data connection between the data carrier unit and the stationary computer unit.
  • the voltage pulse generated by the pulse generator can be temporarily stored as a change in a memory register in the data carrier unit and can be read out by the operating program at a later point in time via the existing data connection, the memory register being reinitialized with the readout.
  • the operating program reads out the memory register in particular between two sequentially transmitted data packets. A renewed voltage pulse can thus be temporarily stored in the memory register.
  • the operating program initiates data synchronization of a predetermined storage area on the stationary computer unit and the external data carrier unit connected via the data transport cable.
  • the data connection can be interrupted.
  • the external data carrier unit is then connected to a further stationary computer unit and the currently stored data on the external data carrier unit are used for data synchronization with another computer unit.
  • the external data carrier unit can in turn also be connected to the original stationary computer unit.
  • the data exchange is optionally monitored by optical aids, in particular LEDs, arranged on the external data carrier unit, which are activated in the event of a data transmission.
  • optical aids in particular LEDs
  • Figure 1 is a schematic representation of the data connection between a stationary computer unit and the external data carrier unit according to the invention.
  • FIG. 1 shows a schematic representation of the data connection between a stationary computer unit 11 and the external data carrier unit 10 according to the invention.
  • the data connection is ensured via a connection port 14 of the stationary computer unit 11 and a pluggable data transport cable 12, 13.
  • An operating program in the stationary computer unit 11 constantly monitors the connection port 14 for a possible data connection.
  • the operating program monitors the push button device 15 integrated in the data carrier unit via the data line 12, 13 to the effect that a voltage pulse is generated by actuating the printing device 15.
  • the voltage pulse can be briefly stored in the form of a change in a memory register 17.
  • the status of the memory register 17 can then be queried by the operating program via the data line 12.
  • the operating program detects this change in the memory register 17 when it is accessed via the data line 12, 13 and reinitializes the memory register 17.
  • the operating program starts further processes in the stationary computer unit 11.
  • data synchronization of a predefined storage disk area on the stationary computer unit 11 and the external data carrier unit 10 is provided here.
  • the operating program in the stationary computer unit 11 controls the data exchange in such a way that between the sequentially transmitted data packets via the existing data line 12, 13, the pushbutton device 15 is actuated again by reading out a new change. tion of the memory register 17 can be detected.
  • the data exchange can be monitored with the aid of a correspondingly controlled LED 16. If the push button device 14 is actuated again, the operating program of the computer unit 11 starts further processes such as. For example, an interruption of data synchronization or an initialization of the operating program.
