Abstract

PROBLEM TO BE SOLVED: To make it possible to judge 'failure' of one collection period of a circuit package as a failure by outputting a timing signal for collecting the monitoring information of plural circuit packages and synchronously storing the monitoring information of respective circuit packages in accordance with the timing signal. SOLUTION: It is supposed that a failure in a circuit package 4.1 exerts influence upon an intra-device monitoring result of a circuit package. When the intra-device monitoring results of the packages 4.1, 4.2 are simultaneously turned to abnormal states, these monitoring results are written in the same address of respective memories 6.1, 6.2 based on timing signals outputted from synchronizing signal generation parts 9.1 to 9.n. Thereby the monitoring result is stored in the memory 6.1 before starting the collection of monitoring information of respective packages 4.1 to 4.n by an intra-device monitoring information collection part 3. Thereby even when the collection part 3 collects the monitoring results of the packages 4.1, 4.2 with a time difference, monitoring results at the same time can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for collecting monitoring result information in a device for transmitting and receiving signals between a plurality of circuit packages. The present invention relates to a device and a method for collecting monitoring information in a device having a property that a failure of a certain circuit package affects a monitoring result of another circuit package.

[0002]

2. Description of the Related Art FIG. 2 shows a conventional method of collecting the results of monitoring in a device (monitoring information). In this figure, the circuit package 4.
The presence or absence of a failure in the signal processing units 8.1 to 8.n of 1 to 4.n is monitored by the in-device monitoring units 7.1 to 7.n of 4.1 to 4.n in each circuit package. Output to the monitoring information processing units 5.1 to 5.n. The in-device monitoring information collection unit 3 in the processing unit 1
In-device monitoring information processing unit 5.1 for each circuit package 4.1 to 4.n
~ 5.n et al. Collects internal monitoring result information using the following serial communication means.

First, the in-device monitoring information collecting unit 3 transmits the multiplexed collection frame to the in-device monitoring information processing unit 5.1 of the first circuit package 4.1. The in-device monitoring information processing unit 5.1 that has received the collection frame
The monitoring result information from 7.1 is encoded into a response frame and transmitted to the in-device monitoring information collection unit 3. Similarly, the in-device monitoring information processing unit 3 sequentially executes the in-device monitoring information processing units 4.2 to 4.2.
4. Send and receive frames to and collect monitoring result information.

[0004] Here, it is assumed that the device has a configuration in which a failure of the circuit package 4.1 affects information on the result of monitoring the inside of the device of the circuit package 4.2 as a partial failure. In this case, according to the conventional information collection method of the in-device monitoring result, if the in-device monitoring results of the circuit package 4.1 and the circuit package 4.2 are simultaneously detected as abnormal, the circuit package 4.1 is determined to be “failed” and the circuit package 4.2 Is determined to be “normal”.

At this time, if a failure of the circuit package 4.1 occurs immediately after the in-device monitoring information collecting unit 3 collects the monitoring information of the in-device monitoring information processing unit 5.1, the monitoring result of the circuit package 4.2 is caused by the failure. It becomes "abnormal", and the monitoring result collected from the in-device monitoring information processing unit 5.2 immediately after that also becomes "abnormal".

In this case, the in-device monitoring information collecting unit 3
First, the monitoring result of the circuit package 4.1 is determined to be “normal”, and thereafter, the circuit package 4.2 is determined to be “abnormal”. Immediately after this, if the failure of the circuit package 4.1 recovers, it is determined to be “normal” in the next collection of the monitoring results of the circuit package 4.1.

In the conventional method of collecting the monitoring results in the apparatus, "failure" of the monitoring result of the circuit package 4.2 is collected due to the failure of the circuit package 4.1, and the circuit package 4.2 is erroneously determined to be "failure". In order to prevent this, the monitoring information collection unit 3 in the device protects the collection of the monitoring result, and the monitoring result of the circuit package 4.1 is “normal” and the monitoring result of the circuit package 4.2 is “abnormal”.
Circuit package when the state of occurs more than once in a row
Protection is provided to judge the failure of 4.2.

[0008]

A first problem is that a "failure" cannot be determined based on information for one cycle of collection of monitoring results (monitoring information) for a circuit package.
That is, in a circuit package in which “abnormality” of the monitoring result is collected due to a failure in another circuit package, a failure of less than one collection cycle cannot be determined to be a failure. The reason is,
In other words, the determination of “failure” is made only when the monitoring result of the circuit package is “abnormal” and two or more monitoring results are collected.

The second problem is that, during the period in which the in-device monitoring and collecting unit is out of order or not mounted, the in-device monitoring result is not collected at all, so that the circuit package is not monitored and the monitoring of the fault is not performed. Cannot be implemented.

Accordingly, an object of the present invention is to provide an in-device monitoring function capable of determining a "failure" in one collection cycle of a circuit package as a failure. Another object of the present invention is to provide an in-apparatus monitoring function for monitoring "failure" even when the in-apparatus monitoring information collecting unit is out of order or not installed.

[0011]

In order to solve the above-mentioned problems, the present invention provides an apparatus having a plurality of circuit packages and a mechanism for constantly monitoring the occurrence of a failure in each circuit package. A means for outputting a timing signal for collecting monitoring information, and means for synchronizing and holding the monitoring information of each circuit package according to the timing signal are provided. In that case, a means for generating a periodic timing signal, a means for holding monitoring information of each circuit package a plurality of times in accordance with the timing signal, and a plurality of synchronizations with the means for holding the monitoring information are provided. And a means for generating the synchronizing signal. Also, a plurality of circuit packages, an in-device monitoring information collecting unit that collects monitoring information for determining whether or not each circuit package has a failure, an in-device monitoring unit that monitors a failure of a signal processing unit, and the device. A memory for holding the monitoring information output from the internal monitoring unit, a synchronization signal generating unit for outputting a synchronization signal for holding the monitoring information in the memory, and an internal monitoring unit for outputting the output of the memory to the internal monitoring information collecting unit It is also possible to adopt a configuration including an information processing unit and a fixed-period signal generation unit that outputs to the synchronization signal generation unit a signal that synchronizes the timing of writing the monitoring information to which position in the memory. On the other hand, in the collection method of the present invention, when collecting monitoring information of a device having a plurality of circuit packages and having a mechanism for constantly monitoring the occurrence of a failure in each circuit package, the monitoring information of each circuit package is synchronized. In this method, the information is stored in the storage means a plurality of times, and the monitoring information is collected from the storage means. In that case, a periodic timing signal for periodically holding the monitoring information of each circuit package in the storage means a plurality of times, and a synchronization signal for synchronizing and holding the monitoring information of each circuit package in the storage means. Can also be used. In addition, the monitoring information of each circuit package is stored in the storage unit a plurality of times based on the periodic timing signal, and the monitoring information holding operation of each circuit package is synchronously stored using a synchronization signal during the holding operation. After that, the monitoring information held in the storage means can be collected as monitoring result information of each circuit package.

A first effect of the present invention is that a means for outputting a signal indicating a timing for collecting the monitoring information of each circuit package and a means for holding the monitoring information in each circuit package make the collection timing of the monitoring information in the apparatus possible. Since the entire system is synchronized, there is no difference in the monitoring results due to the time difference of the collection timing between the circuit packages, and there is no need to provide protection for the monitoring result information collection. Thus, it is possible to determine whether or not there is a failure in that part.

A second operation of the present invention is to generate a timing signal which is periodically held even when the in-device monitoring processing part which generates the in-device monitoring information collection timing is faulty or not mounted. The means and the means for holding the output of the in-device monitoring result information a plurality of times with the signal generated thereby can hold the in-device failure information and perform the in-device monitoring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. Referring to FIG.
The processing unit 1 includes an internal monitoring information collection unit 3 that collects information on an internal monitoring result for determining the presence or absence of a failure in the n circuit packages 4.1 to 4.n, and a memory 6.1 to 6.n. It has a fixed-period signal generation unit 2 that outputs a signal for synchronizing the timing of writing the monitoring result information to which position in the memory to the synchronization signal generation units 9.1 to 9.n of each of the circuit packages 4.1 to 4.n. I have.

Each of the circuit packages 4.1 to 4.n includes a signal processing unit 8.1 to 8.n and an in-device monitoring unit 7.1 to 7.n for monitoring a failure of the signal processing unit 8.1 to 8.n. And memory 6.1 to hold the monitoring result information output from the internal monitoring units 7.1 to 7.n at the output timing of the synchronization signal generation units 9.1 to 9.n.
6.n, and internal monitoring information processing units 5.1 to 5.n that output the outputs of the memories 6.1 to 6.n to the internal monitoring information collection unit 3.

Next, the operation will be described with reference to FIG. In-device monitoring unit 7.1 for circuit packages 4.1 to 4.n
To 7.n constantly monitor the occurrence of an abnormality in the corresponding signal processing unit 8.1 to 8.n, and a signal indicating the presence or absence of the abnormality is stored in the memory 6.
Output to 1 to 6.n respectively. The memories 6.1 to 6.n hold a plurality of signals from the in-device monitoring units 7.1 to 7.n, that is, information on monitoring results, in synchronization with the signals from the corresponding synchronization signal generating units 9.1 to 9.n.

Each of the synchronizing signal generators 9.1 to 9.n generates a timing of writing to a memory address in n memories 6.1 to 6.n in the apparatus. The in-device monitoring information collection unit 3 transmits the multiplexed serial signal to the in-device monitoring information processing unit 5.1 of the first circuit package 4.1. The in-apparatus monitoring information processing section 5.1 responds to the in-apparatus monitoring information collection section 3 as a multiplexed serial signal of a plurality of monitoring results held in the memory 6.1. Next, the in-device monitoring information collection unit 3 collects monitoring results from the in-device monitoring information processing unit 5.2 of the circuit package 4.2 in the same procedure. This procedure is sequentially repeated for n circuit packages 4.1 to 4.n.

Here, it is assumed that the failure of the circuit package 4.1 has affected the in-device monitoring result of the circuit package 4.2. If the monitoring results in the devices of the circuit package 4.1 and the circuit package 4.2 become abnormal at the same time, these monitoring results are the same in the respective memories 6.1 and 6.2 by the timing signals output from the synchronization signal generators 9.1 to 9.n. Is written to the address.

Therefore, since the monitoring result is held in the memory 6.1 before the in-device monitoring information collecting unit 3 starts collecting in each circuit package, the in-device monitoring information collecting unit 3 transmits and receives the multiplexed frame. Use the circuit package
Collect the monitoring results of 4.1 and wait a while for the circuit package
Even if the monitoring result of 4.2 is collected, the monitoring result of the in-device monitoring unit at the same time can be obtained.

At the same time as the monitoring result in the device becomes “abnormal” in the device monitoring section 7.1 of the circuit package 4.1, the circuit package
If the monitoring result in the device in 4.2 in-device monitoring unit 7.2 is “abnormal”, the synchronization signal generation unit 9.1 and the synchronization signal generation unit
Since the information is simultaneously held in the memories 4.1 and 4.2 at the timing output from 9.2, the in-device monitoring information collecting unit 3 determines that the circuit package 4.1 is “failed” and the circuit package 4.2 is determined to be “normal”. .

If the processing unit 1 is faulty or not mounted, the synchronization signal generation unit of each of the circuit packages 4.1 to 4.n
The monitoring results of the in-device monitoring units 7.1 to 7.n are written to the memories 6.1 to 6.n by the outputs of 9.1 to 9.n. Therefore, when the failure of the processing unit 1 is restored or implemented and the state becomes a normal state, by reading the information from the in-device monitoring information collecting unit 3, the in-device monitoring result can be obtained.

The unit 11 transmits a signal from the transmission circuit 14 to the reception circuit 15.

The in-device monitoring information collection unit 3 of the processing unit 1 is connected to the in-device monitoring information processing units 5.1 to 5.3 of the clock supply unit 10, the data transmission unit 11, and the data reception unit 12, respectively. The transmission and reception of frames are sequentially performed using the serial frames. The in-device monitoring unit 7.1 of the clock supply unit 10 monitors the clock signal of the clock generation unit 13 and outputs the presence or absence of an abnormality to the memory 6.1 as a signal.

The transmission circuit 14 of the data transmission unit 11 and the reception circuit 15 of the data reception unit 12 monitor the occurrence of a failure by their internal monitoring units 7.2 and 7.3. Also, the transmission circuit 14,
The in-device monitoring units 7.2 and 7.3 of the receiving circuit 15 are output to the memories 6.2 and 6.3 of the data transmitting unit 11 and the data receiving unit 12, respectively.

The in-device monitoring information collecting unit 3 of the processing unit 1 transmits the clock supply unit 1 through the in-device monitoring information processing units 5.1 to 5.3.
0, before collecting the monitoring results of each of the data transmitting unit 11 and the data receiving unit 12, by outputting the timing address from the counters 16.1 to 16.3 of each unit a plurality of times at the same interval, the internal monitoring of each unit is performed. The result is stored in the memory 6.1 to 6.3. Further, the fixed-period signal generation unit 2 periodically resets each of the counters 16.1 to 16.3.

Thereafter, the in-device monitoring information collecting unit 3 first
The collected frame of the monitoring result is transmitted to the clock supply unit 10 to the in-device monitoring information processing unit 5.1 of the clock supply unit 10. The clock supply unit 10 stores the memory while receiving the frame.
The information of 6.1 is transmitted to the in-device monitoring information collection unit 3 as a response frame through the in-device monitoring information processing unit 5.1.

Next, the in-device monitoring information collecting unit 3 sequentially performs the monitoring result of the data transmitting unit 11 and the data receiving unit 12 in the same procedure.

In FIG. 3, when a failure occurs in the clock generation unit 13, the monitoring result of the in-device monitoring unit 7.1 of the clock supply unit 10 becomes abnormal, and at the same time, the transmission unit 14 and the reception circuit 15 Since the clock is distributed, the transmission circuit 14 and the data reception unit 12 of the data transmission unit 11
Monitoring unit connected to each of the receiving circuits 15
Abnormalities are detected simultaneously in 7.2 to 7.3 and output to the memories 6.2 to 6.3.

Clock generating unit 13, transmitting circuit 14, receiving circuit
Since the monitoring results of 15 are always held in the respective memories 6.1 to 6.3 at the same time,
Until the timing held in 6.3 occurs, the monitoring information collection unit 2 in the device collects all the collected results of each unit as “abnormal”, and the transmission circuit due to the failure of the clock generation unit 12
13. It can be determined that the monitoring result of the receiving circuit 14 has become abnormal.

When only the transmission circuit 14 fails,
The monitoring result of the transmission circuit 13 and the monitoring result of the clock generation unit 12 are simultaneously abnormal during the time from when the monitoring information collection timing generation unit 2 outputs the holding timing to when the next timing is output, that is, during one collection period. Therefore, it can be determined that the failure of the transmission circuit 14 has occurred.

Also, when the processing unit 1 is not mounted, the counters 16.1 to 16.3 run by themselves and continue to write the monitoring result outputs of the in-device monitoring units 7.1 to 7.3 to the memories 6.1 to 6.3. The monitoring in the apparatus can be continued for a period until writing to all the areas of the memories 6.1 to 6.3 is completed.

[0032]

A first effect of the present invention is that a "failure" in one collection cycle of a circuit package can be determined as a failure. The reason is that the monitoring results of each circuit package are simultaneously held and collected in order.

A second effect of the present invention is that the internal monitoring can be performed by the capacity of the memory even when the internal monitoring information processing section is not functioning. The reason is that the counter of each circuit package runs by itself and accumulates the monitoring result in the device in the memory.
