Description

  The present invention relates to state monitoring using a wireless IC tag in an electronic device.

  In performing maintenance of an electronic device, monitoring the component devices of the electronic device is one of the important elements. For example, when an electronic device breaks down, it takes time to identify the location of failure and cause of failure, so record the history of the operation and temperature of the component device and refer to the log data that is the record. Therefore, the time for identifying the failure part and the cause of the failure is shortened. Further, in periodic maintenance, it is confirmed whether or not an abnormal state has occurred by using log data, and the apparatus is replaced as necessary.

  Patent Document 1 discloses a means for acquiring log data regardless of whether power is supplied to the electronic device.

  Patent Document 1 includes a wireless transmission / reception control device, an antenna, and a device equipped with a wireless IC tag. The result of analysis by a BMC (Baseboard Management Controller) that controls a motherboard is used as a wireless transmission / reception control device and an antenna. The means for transmitting to the wireless IC tag of each device, recording the log data on the wireless IC tag, and acquiring the log data of the wireless IC tab with an external wireless module is disclosed.

Is provided. In addition to this, in the example of FIG. 1, the apparatus includes a component device 40 (40 </ b> A to 40 </ b> E) that is an independent device and is a monitoring target, and a signal circuit 50 that is a signal transmission path. Monitoring data is transmitted via the wireless IC tag. The monitoring data includes temperature, voltage, current, temporary write error, and the like, and the monitoring data varies depending on the component device 40.

  The wireless IC tag 20 is associated with the monitoring target and stored in the monitoring storage unit 13 described below.

  The monitoring target may be a configuration device 40 constituting the electronic device 100, a monitoring group including a plurality of configuration devices 40 as one group, monitoring data in monitoring information, and the like.

  2 to 4 are diagrams illustrating an example of association with the wireless IC tag stored in the monitoring storage unit 13. The tag coordinates indicate the center coordinates of the wireless IC tag displayed on the electronic paper.

  FIG. 2 shows an association with the component device 40, and is an example in which one wireless IC tag 20 is provided for each component device 40. The configuration example of the electronic device 100 is as shown in FIG.

  FIG. 3 shows an association with a monitoring group, which is an example in which grouping is performed according to the position in the electronic device 100, and one wireless IC tag 20 is provided for each monitoring group. A configuration example of the electronic device 100 is shown in FIG. It becomes like 5.

  FIG. 4 shows the association with the monitoring data, and is an example in which one wireless IC tag 20 is provided for each type of monitoring data, and the configuration example of the electronic device 100 is as shown in FIG.

  FIG. 7 is a diagram illustrating a configuration example of the monitoring control unit 11 in the BMC 10.

  The monitoring control unit 11 in the BMC 10 includes a state monitoring unit 12 that monitors monitoring data, a monitoring storage unit 13 that stores associations of wireless IC tags, a writing processing unit 14 that performs writing processing on wireless IC tags, A display processing unit 15 that performs display processing on electronic paper.

  Processing in the monitoring control unit 11 will be described.

  FIG. 8 is a flowchart illustrating a processing example of the monitoring control unit 11.

  The status monitoring unit 12 receives and monitors the monitoring data of the configuration device 40 every time the configuration device 40 operates (S11), and if not normal, instructs the display processing unit 15 to display the electronic paper. The occurrence of abnormality is displayed on (S12). In the case of sensors that are constantly operating, the component device 40 manages the cycle and transmits monitoring data, or the state monitoring unit 12 manages the cycle and requests transmission of monitoring data. The configuration apparatus 40 transmits monitoring data.

  Next, the state monitoring unit 12 instructs the write processing unit 14, and the write processing unit 14 stores the monitoring information in the wireless IC tag (S13).

  Next, the state monitoring unit 12 determines whether or not there is a serious abnormality (S14), and if it is a serious abnormality, the display processing unit 15 is instructed, and the display processing unit 15 displays the serious abnormality on the electronic paper ( S15).

  For example, when the cumulative number of abnormalities exceeds a predetermined number, abnormalities in unit time exceed a predetermined number, or the value of monitoring data greatly exceeds a normal value, the state monitoring unit 12 It is determined that a serious abnormality has occurred. Note that the monitoring storage unit 13 stores a condition for determining whether or not it is normal and a condition for determining the occurrence of a serious abnormality.

  Here, as shown in FIG. 9, the wireless IC tag can be stored only when the monitoring data is not normal.

  Electronic paper will be described.

  Electronic paper is a non-energized display holding device that requires a power source when switching display contents but does not require a power source when holding display contents.

  As shown in FIG. 10, the display of the occurrence of an abnormality displays the latest date and time of the occurrence of the abnormality and the cumulative number of occurrences. If a serious abnormality occurs, the color is further changed.

  The monitoring target can be an area unit obtained by dividing the electronic device 100 into a plurality of monitoring areas.

  FIG. 11 is a diagram illustrating an example in which the electronic device 100 is divided into a plurality of monitoring areas (area P to area S) and monitored in units of areas.

  The electronic device 100 arranges the wireless IC tags 20 (20P to 20S) according to the areas, for example, collects temperature sensors for each area, stores the monitoring information in the wireless IC tag 20, and when a serious abnormality occurs, FIG. Can be displayed.

  As described above, by displaying the wireless IC tag storing the history of the occurrence of abnormality using electronic paper or the like that does not require a power source for maintaining the display state by dispersing and storing the monitoring information, For example, since a wireless IC tag that acquires log data can be limited when a failure occurs or during regular maintenance, it is not necessary to acquire all log data, and the number of man-hours for maintenance work can be reduced. In addition, it is possible to eliminate the need for confirmation of the radio wave state at the initial stage of installation. Further, the wireless transmission / reception control device and the antenna can be dispensed with.

  Therefore, regardless of whether power is supplied to the electronic device, monitoring in the electronic device can be performed more inexpensively and more efficiently.
