Definitions

  • the invention relates to a system for automatic drive detection and control.
  • jukeboxes With the increasing use of CDs, i.e. Co pact disks, collection magazines, so-called jukeboxes, are used, so that a new CD does not have to be used for every record change by hand. Typically, the jukeboxes are now equipped with multiple drives to meet the speed requirements.
  • CD-ROM technology has continued to develop, and various types of CD drives are becoming available, for example of the CD-ROM, CD-Recordable, CD-Eraseable type, ie there are not only read drives, but also LOE ⁇ rule and / or write, also those which are described with lower and higher density.
  • phase change technology has also been developed.
  • a medium is used for data storage, which can be repeatedly brought from amorphous to crystalline state and vice versa by means of heat input. The heat is introduced using a laser.
  • the invention has for its object to provide a system that enables the detection of the drive type and is suitable for use in a jukebox.
  • a system for drive detection and control thus comprises one or more drives, each of which is provided with a printed circuit board which bears an identification identifying the drive as information, a connecting line between the printed circuit board and a control unit which controls the operation of the drive, and a device in the control unit that queries the drive identifier and sets the machine parameters accordingly.
  • drives can be installed as required, regardless of the respective installation location in the jukebox concerned.
  • the control unit of the jukebox asks about the connection line, which is preferably in one component, for example a ROM, stored binary identifier of the drive and then sets the machine parameters accordingly.
  • the drive type is determined, for example, whether it is a read-only drive or a read-write drive, etc.
  • the drive type also determines installation height, electrical control, CD type , etc.
  • the control unit then accordingly activates the control program associated with the drive type.
  • An identifier is also provided for so-called generic drives. These drives are not of one of the standard types and have their own control unit. In this case, the system control unit works in such a way that it takes over the identification of the drive and the command transfer for the drive operation, ie it specifies the functions to be performed. It is not necessary to change the control program of the system control unit, since the control commands are basically made up of control signals that are independent of the drive. Provision can furthermore be made to use device data of the drive, such as installation height, manufacturing time and location, serial number for operating sequences, for example loading, and maintenance and repair work, from the storage unit of the drive control unit. A transfer to an advertisement and a service device can take place.
  • a connecting line expediently a bus system, is provided for the information exchange between the drive and the jukebox.
  • the amount of data that can be exchanged via such a bus system is arbitrarily high, so that the number of drives is not restricted in this regard.
  • An adapter box can be provided between the connecting lines leading to the individual drives and a bus leading to the control unit.
  • the connecting lines preferably lead directly to the control unit.
  • FIG. 1 is a schematic front view of a jukebox according to the invention
  • Fig. 2 is a block diagram of the Erkennungsssystems according ei ⁇ nem first embodiment of the invention.
  • Fig. 3 is a block diagram of the detection system according to a second embodiment of the invention.
  • Fig. 1 illustrates a jukebox 2 with several drives 4 (4a, 4b, ..., 4n).
  • the drives 4 are not all of the same type. They are all provided with a printed circuit board 6 (6a, 6b, ..., 6n).
  • the circuit boards 6 each carry a component, such as a ROM, in which the drive identifier is stored is.
  • the drive type is coded in the drive identifier. This shows whether the drive in question is a read-only drive or, for example, a read-write drive.
  • each printed circuit board 6 is connected to a control unit 12 of the jukebox 2 via a connecting line 8 (8a, 8b, ..., 8n) and a bus 10.
  • the control unit queries the drive identifiers via the bus system 8, 10 and sets the operating parameters in accordance with the information received. For example, if the drive 4a is a read / write drive with a high data write density (high density), then the drive is set to the corresponding speed and the magnetic field is provided in accordance with the read or write operation. It is also provided that this drive can be used at all if a write command is given. This can be done automatically by controlling the jukebox and without user input.
  • the control of the jukebox recognizes the changed hardware and sets the machine parameters accordingly.
  • an initialization procedure can be provided in which the jukebox checks the configuration of the existing drives after being switched on and sets the parameters accordingly.
  • the connecting lines 8a to 8n lead to an adapter 9, from which a bus 10 leads to the control unit.
  • the 3, the control lines 8a to 8n lead directly to the control unit 12.
