Each include a terminal interface to which a terminal device (not shown) is connected.

The control package 12 includes a fault monitor 12
1, a fault collecting unit 122, a mounting information monitoring unit 123, a mask processing unit 124, a fault processing unit 125, and a highway data interface unit 126.

The fault monitoring unit 121 is connected to all package mounting units, monitors highway data from the terminal package 13 mounted on the package mounting unit, and detects a fault. When a failure is detected, the failure collection unit 122 is notified that the failure has been detected.

The fault collecting unit 122 is connected to all package mounting units and collects individual fault information from the terminal package 13 mounted on the package mounting unit. And
The failure information notified from the failure monitoring unit 121 is added to the collected individual failure information, and the result is output to the mask processing unit 124 and the failure processing unit 125.

The mounting information monitoring unit 123 is connected to all package mounting units, monitors mounting information from the terminal package 13 mounted on the package mounting unit, detects whether the terminal package 13 is mounted or not, and If there is an unmounted terminal package, a mask instruction is issued to the mask processing unit 124. At the same time, the mounting information monitoring unit 123
The mounting mode information indicating whether the detected terminal package is mounted or not mounted is output to the interface package 15.

The mask processing unit 124 includes the mounting information monitoring unit 1
When a mask instruction is given from 23, the failure collecting unit 122
With reference to the failure information from, a mask instruction is issued to the failure processing unit 125 and the highway data interface unit 126.

The failure processing unit 125 analyzes the failure information from the failure collection unit 122, assigns priorities, and outputs it to the interface package 15. At this time, if a mask instruction is input from the mask processing unit 124, mask the failure information from the designated package mounting unit in accordance with the instruction, and assign priority to the remaining failure information to the interface package 15. Output.

Highway data interface section 126
Outputs the highway data from the terminal package 13 transmitted via the failure monitoring unit 121 to the interface package 15. At this time, the mask processing unit 12
If a mask instruction has been input from No. 4, the highway data corresponding to the specified package mounting unit is masked according to the instruction.

The interface package 15 adds the fault information from the fault processing unit 125 to the highway data input from the highway data interface unit 126,
It multiplexes the mounting form information from the mounting information monitoring unit 123 and sends it to the host device 14.

Hereinafter, the operation of the control package 12 will be described in detail.

Each of the terminal packages 13 mounted on the package mounting section transmits highway data to the host device. This highway data is transmitted to the fault monitor 1
21. In addition, each terminal package 13 monitors a failure occurrence state in its own package, and outputs individual failure information when a failure occurs. This individual failure information,
The data is input to the failure collection unit 122. Furthermore, each terminal package 13 outputs mounting information, and this mounting information is input to the mounting information monitoring unit 133.

The fault monitor 121 time-division multiplexes the highway data output from each terminal package 13. Then, for the multiplexed highway data,
Check the health of the data. That is, the failure monitoring unit 1
21 is a CRC for the multiplexed highway data.
Check for errors and parity errors. Here, multiplexing of highway data is performed in the terminal package 1
No. 3 is implemented regardless of implementation / non-implementation. That is, multiplexing is performed on the assumption that highway data exists as many as the number of package mounting units. For this reason, if there is a package mounting part where the terminal package is not mounted,
The bit of the multiplexed highway data corresponding to the package mounting unit is undefined, and an error is detected (determined as a failure of the highway data or a package failure). Fault monitoring unit 12 that has detected an error
1 notifies the failure collection unit 122 of the error detection.

The fault collecting unit 122 is provided for each terminal package 1
3 collects the individual fault information from the
In addition to the error detection notification from 21, in addition to the collected individual failure information, failure notification information is notified to the failure processing unit 125 and the mask processing unit 124.

The mounting information monitoring section 123 monitors mounting information from each terminal package 13. Thus, the mounting information monitoring unit 123 detects whether the terminal package is mounted on the package mounting unit. Then, mounting mode information indicating mounting / non-mounting of the terminal package is output to the interface package 15. If there is a package mounting unit on which the terminal package is not mounted, a mask instruction regarding the package mounting unit is output to the mask processing unit 124.

The mask processing unit 124 includes the mounting information monitoring unit 1
When the mask instruction is received from 23, it refers to the failure information from the failure collection unit 122, and checks whether there is failure information for the package mounting unit specified by the mask instruction. Then, when there is fault information on the package mounting unit specified by the mask instruction, the mask processing unit 124
A failure mask instruction for masking the failure information is output to the failure processing unit 125. Also, the mask processing unit 124
Outputs a data mask instruction to the highway data interface 126 to mask the bit data of the highway data corresponding to the package mounting section.

The failure processing unit 125 masks the failure information corresponding to the package mounting unit specified by the mask processing unit 124 from the failure information from the failure collection unit 122. Then, priority is added to the remaining fault information according to the degree of importance, and the fault information is output to the interface package 15. As a result, the fault information on the package mounting unit on which the package is not mounted is not transmitted to the host device. It should be noted that the failure information having a lower priority may not be notified to the higher-level device.

The highway data interface unit 126 corresponds to the package mounting unit specified by the mask instruction from the mask processing unit 124 in the highway data sent from the terminal package 13 via the fault monitoring unit 121. The highway data of the corresponding bit is masked and this highway data is output to the interface package 15. As a result, the highway data including the error is not transmitted to the host device.

The host device 14 receives the highway data transmitted from the interface package 15 to the transmission path. In the highway data, failure information from the failure processing unit 125 and mounting form information from the mounting information monitoring unit 123 are multiplexed. The failure information received by the higher-level device 14 does not include (is masked) failure information relating to unmounted packages. Therefore, the host device 14 does not need to perform the processing at the time of failure for an unmounted package, and need only perform the processing at the time of failure for the mounted terminal package 13. This is effective, for example, when the terminal package 13 is being replaced. As a result, the load of the fault processing on the host device is reduced, and quick fault processing becomes possible. Note that the host device 1
4 is performed based on the priority assigned by the failure processing unit 125.

Since the highway data received by the higher-level device 14 does not include indefinite data in the bits corresponding to the unmounted packages, it is unlikely that the indeterminate data causes a failure on the higher-level device side. Absent. In addition, even when data cannot be obtained from a specific bit, the maintainer of the higher-level device side, based on the mounting form information,
You can check whether the package is mounted or not.

[0044]

According to the present invention, mounting / non-mounting of a terminal package which is a monitored device is monitored, and failure information based on data from the unmounted mounting means is masked. The fault processing load on the host device can be reduced, and as a result, the circuit configuration of the host device can be simplified.

Further, according to the present invention, when the terminal package is not mounted, the failure information is not notified to the higher-level device. There is also an effect that the replacement of the battery can be easily performed.
