Abstract

A remote diagnosis system by which the surface of faults is indicated on the outside of the copier uses function elements (CW) within the supply equipment (N1, N2, Nn) to analyse faults. This data is registered on data-receivers (CAN1, CAN2, CANn) which are coupled through a bus system (CANBUS) to a data receiver (CAN4) on the remote diagnosis unit (DM). According to the information received this can be used to trigger an emergency supply (UW). It may also be linked to a server unit (BF) and/or a modem (MO)

Description

Power supply devices come in various technical Devices installed. For example, power supplies devices in electrographic printing or copying devices builds. In such or similar large and therefore confusing technical equipment, it is the supplier in the event of malfunctions voltage difficult to analyze the source of the error. Power supply devices can therefore self-diagnose direction included, which determine a reason for failure and at for example, a display element on the outside of the housing Taxes.

Diagnostic devices of this kind make it easier to make mistakes lyse, but require direct access to the Power supply device. Falls a power supply advises during the operation of the electrotechnical device, then its housing must be opened and often not easy feasible access to the power supply device consequences. Electrotechnical devices, however, must be opened be switched off so that in electrical engineering Units contained in the device must be taken out of operation sen. After switching on again, you have to wait until all units are ready for operation again.

The invention has for its object a remote diagnosis Device and method for remote diagnosis for voltage ver care facilities of an electrotechnical device show a fault diagnosis of the voltage supply Direction also possible outside of the electrotechnical device light.  

This object is solved by claims 1 and 6. Developments and refinements of the invention are in Un claims specified.

By equipping the voltage supply devices with a data interface, the error analysis unit of the Power supply device fault analysis data immediately enroll in cash. This data interface can make changes the data entered in it using ei ner suitable data transmission device to a remote slide transmission unit. This means that when an error occurs lers the possible cause from outside or in the case of a distance diagnosis is done from a remote location. Before switching off of the electrotechnical device can be recognized whether a Continued operation of the electrical device despite the up occurring error is possible. In addition, needed Spare parts are procured before business interruption. A Repairs can be carried out at the right time in the shortest possible time time.

According to an embodiment and development of the invention an emergency power supply is assigned to the data interface, a si if the power supply device fails Safe transfer of the error analysis data to the missing slide guaranteed unit. It becomes the data interface position enables the possible Cause still as a message via the data transmission system to discontinue. The remote diagnosis unit is therefore in any case the current information is available.

The following is an example of the invention based on the Drawing explained in more detail. Show

Fig. 1 is a block diagram with remote diagnosis unit, data transmission path and voltage supply devices and

Fig. 2 is a block diagram of a voltage supply device with voltage converter, control device and data interface.

A plurality of functional units, such as a fixing station, a character generator and a paper transport device, are contained in an electrographic printing or copying device. These require a variety of different supply voltages. These supply voltages are determined by a corresponding number of voltage supply devices N1. . Nn, as shown in Fig. 1, ge available. Each power supply unit N1. . Nn, is a data interface CAN1. . CANn assigned. The data interface is CAN1. . CANn are coupled with each other via a CANBUS bus system. A remote diagnosis unit DM, which also contains a CAN4 data interface, is via the same CANBUS bus system. The remote diagnostic unit DM receives the data and stores it in a system memory of the printing or copying device. It delivers data to the printer's own control panel BF and / or to a data modem MO, which can be accessed from any location via public or private communication networks.

As shown in FIG. 2, a voltage supply device N contains the actual voltage converter WA, a control device TW for controlling and analyzing the voltage converter WA and a data interface CAN. An emergency power supply UN is also assigned to the CAN data interface. By means of this emergency power supply UN, sufficient energy can still be made available in the event of a failure of the supply voltage of the data interface CAN, since it can still be used to transmit the error event that occurred last in the voltage supply device to the remote diagnosis unit DM.

For transferring data between the data interfaces CAN1. . CANn, a controller area network (CAN) bus is inserted  puts. This CAN bus is in the CAN bus specification 2.0, Parts A and B from April 1994 of Philips be more precise wrote. The CAN bus works after a serial communication cation protocol and is message-driven. Kick in one of the interconnected data interfaces CAN1. . CANn If a data change occurs, the other will immediately be informed Data interfaces CAN1. . CANn communicated. This process is automatically through the communication protocol of the CAN bus table supports.

Another advantage of connecting the power supply directions of the printing or copying machine by means of the CAN Busses is that status information of the power supply facilities N1. . Nn are always available. For example can always be determined that certain tensions before lie or not available. In addition, the Span voltage supply devices N1. . Nn remotely activated and de to be activated.
