Abstract:
An error information reporting system of the present invention is applicable to an error monitoring system including a CPU (Central Processing Unit) and data output terminals. When a critical error occurs in a device being monitored, all data necessary for analysis and remedy are immediately sent to all expected destinations.

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to an error monitoring system including a CPU (Central Processing Unit) and a data output terminal and, more particularly, to an error reporting system for an error monitoring system. 
     An error monitoring system for monitoring devices included in the system and sending error information representative of errors to the outside of the system is conventional. Today, not only a display and a printer but also a facsimile apparatus and an electronic mail using a telephone circuit are usable with the error monitoring system. However, the kinds and amounts of information which can be output are limited by the outputting capability of a display or that of a printer. Moreover, the error information include only minimum necessary information to be output to a display or a printer connected to the system. Specifically, in the event of a critical error, necessary information are too much in amount to be fully output. As a result, although the occurrence of an error may be reported, it is often impractical to remove the error only with the output information. This requires a person to obtain additional information by communicating with or traveling all the way to a station where the system is situated. In addition, because the error information are fixed, not all necessary information are output in the event of an error. This is likely to prevent all necessary information from being collected when an error occurs again. 
     Technologies relating to the present invention are disclosed in, e.g., Japanese Patent Laid-Open Publication Nos. 2-51925, 2-283137, 3-101539, 4-109728, 5-227316, 5-244300, 7-255087, 7-297826, and 7-321913. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the present invention to provide an error information reporting system capable of reporting, when a critical error occurs, all necessary information to all necessary destinations immediately, thereby obviating confusion in the event of data collection and enhancing rapid removal of the error. 
     An error information reporting system of the present invention includes an error information outputting unit. An interface controls the error information outputting unit. A desired device is monitored as to an error thereof. A CPU detects error information representative of an error occurred in the device, searches for a key word corresponding to the error information, references a collected error information table listing collected error information corresponding to the key word, selects the collected error information corresponding to the key word out of the collected error information table, and sends the collected error information to a destination corresponding to the kind of the error represented by the collected error information by using transmitting means assigned to the destination.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to FIG. 1 of the drawings, an error information reporting system embodying the present invention is shown. As shown, the system includes a CPU  2  having a storage  1 . Device  3  to be monitored and an output interface  4  are connected to the CPU  2 . A display  5 , a printer  6 , a facsimile apparatus  7  and an electronic mail transmitter/receiver  8 , which are data output terminals, are connected to the CPU  2  via the output interface  4  The facsimile apparatus  7  and electronic mail transmitter/receiver  8  are respectively connected to a remote facsimile apparatus and a remote electronic mail transmitter/receiver by a telephone circuit although not shown specifically. 
     In operation, the CPU  2  monitoring the devices  3  detects any error occurred in any one of the devices  3 . The CPU  2  sends information representative of the error to the display  5  and printer  6  via the output interface  4 . The information include information identifying the faulty device  3 , information indicative of the degree of criticality of the error, and minimum necessary data. The CPU  2  checks, among such factors, the degree of criticality of the error. If the error is critical, the CPU  2  references a collected error information table shown in FIG.  3  and listing data to be output beforehand. The CPU  2  selects all data of the error information table designated by a coincident key word and writes them in the storage  1 . Further, the CPU  2  references a destination and transmitting means table shown in FIG.  4  and also listing data to be output beforehand. Then, the CPU  2  sends the data stored in the storage  1  to a destination designated by a coincident key word by using transmission means also designated by the key word. 
     A more specific operation of the error information reporting system will be described with reference to FIGS. 2,  3  and  4 . As shown in FIG. 2, assume that a circuit error occurs in a device A (see FIG. 3) included in the devices  3  and is reported to the CPU  2 . The CPU  2  sends the resulting error information received from the faulty device  3  to the display  5  and printer  6  (step S 1 ). Subsequently, the CPU  2  determines, based on the error information, the degree of criticality of the above error (step S 2 ). If the error is critical (YES, step S 2 ), the CPU  2  searches the key words of the collected error information table shown in FIG. 3 (step S 3 ). In this case, a key word “Device A” is coincident with the error information, so that the CPU  2  selects collected data “Device A Status Control Table” corresponding to “Device A” (step S 4 ). Further, because an item “Circuit Error” shown in FIG. 4 is coincident with the received information, the CPU  2  selects destinations and transmitting means associated with “Circuit Error” (step S 5 ). Finally, the CPU  2  sends the collected data to one designation “03-3456-7890” via the facsimile apparatus  7 , FIG. 1, and sends them to the other destination “abc@xyz. co. jp” via the electronic mail transceiver/receiver  8 , FIG.  1 . 
     In summary, in accordance with the present invention, necessary information can be additionally registered in association with past data. This allows sufficient data relating to any kind of error to be collected and thereby enhances rapid error analysis and remedy. In addition, desired destinations can be additionally registered or deleted, so that all necessary error information can be reported to expected destinations and analyzed there. 
     Various modifications will become possible for those skilled in the art after receiving the teachings of the present disclosure without departing from the scope thereof.
