Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an electronic switching system that has improved software tracing functions to facilitate debugging.

(Prior Art) Private branch exchanges have become more and more convenient as they have become more sophisticated through computerization, and have become capable of adding various service functions desired by users in addition to their original telephone exchange operations. By the way, these various functions are realized by software, and when developing that software,
First, we set the target program we had developed on the actual machine through a maintenance terminal, which is a man-machine interface connected to the exchange, for input/output operations of data and commands, and conducted a test run.After confirming the operation, we put it into practical use. I am trying to provide it. Therefore, the control unit, which is the center of control of the exchange that executes this program, has a debug mode that executes the program in trace mode.In order to execute this mode, commands are given from the maintenance terminal, and the above development program is executed using an extension telephone, etc. Let's try implementing it.

Here, the task trace function in conventional private branch exchanges records the status of each extension telephone, outside line, and various terminals, as well as a series of tasks (hereinafter referred to as task pages) performed by software on various terminals, in each task page. This is a tracing function that collects and maintains data for each task page, including terminal data that determines which terminal the task page acted on, the current status of the terminal, address information of the task page, etc. The data is edited, displayed, output to a printing device, etc. using a terminal, and is used as bug analysis data when a bug occurs. According to such a conventional system, it is possible to easily know the operation status and status of each terminal and which task page has been executed at the time when a bug occurs, and debugging efficiency can be improved.

(Problems to be Solved by the Invention) As described above, the private branch exchange implements various functions using software, but it is equipped with a task trace function in order to debug software such as new functions developed. The task trace function provided in conventional private branch exchanges is
The status of each extension telephone, external line, and various terminals, and the task page (a series of tasks) performed by the software on various terminals.
This is a function that traces each task page.

Then, the terminal data that determines which terminal the task page acted on, the current status of the terminal, the address of the task page, etc. are collected as data for each task page, and the data is collected using the maintenance terminal. You can edit, display, etc., and use it as bug analysis data when a bug occurs. According to such a conventional system, it is possible to easily know the operation status and status of each terminal and which task page has been executed at the time when a bug occurs, and debugging efficiency can be improved.

However, each task page accommodates a plurality of tasks, and for example, when a serious bug such as a system failure occurs, it is difficult to determine which task ultimately caused the failure. In addition, when collecting and analyzing task trace data in order to reproduce a bug that occurred on a customer site, there is no data to know the execution time of the task page, so we have to investigate all the huge amount of task trace data. The problem was that it took a long time to reproduce the bug.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electronic switching system that can collect and store information on the total number of executed tasks and the time when a task page was executed.

[Configuration of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention is configured as follows. In other words, an electronic switching system that has a trace function that executes required switching operations using software and traces the execution state transition of the software,
The electronic exchange includes a clock means for generating time information, and a time data recording means for obtaining and storing ↑h information of the traced time from the clock means for each trace data unit of execution state transition trace data. The present invention is configured by providing a task counting means for storing information on the total number of executed tasks, and a transmitting means for externally transmitting information on tracing time and information on the total number of tasks for each trace data unit together with the execution state transition traced data. Also, as an output device connected to this electronic exchange and used, there is a trace data storage means for receiving the transmitted data and saving it in a file, and a trace data storage means for editing the file in which the trace data is stored and outputting it to the output means. The trace data editing means is configured using a device having a trace data editing means.

(Function) In such a configuration, the electronic exchange, after collecting conventional task trace data when executing the task page, reads the time data from the clock means of the electronic exchange, converts the format of the time data, and identifies the specific information in the task trace data. Time data is recorded in the data section using a recording means.

Next, the task count section in the task trace data is cleared, and thereafter, each time a task in the same task page is executed, the task count means counts up the task counter. Next, all the task trace data is sent to the output device using a sending means that has an added function of sending the task counter and time data part to the outside. The output device receives all transmitted data using a receiving means, stores it as a trace data file, edits the trace data file using a trace data editing means, and outputs it as a task trace file.

In this way, the present invention adds data called a task counter that manages information on the total number of executed tasks to conventional task trace data, and time data that stores the execution time of tasks, so that the current time information is updated every time a task page is executed. Gain,
The task counter is incremented each time a task is executed during the task page, and the time data and task count value thus collected are sent to the output device along with conventional task trace data. The output device receives all the task trace data including the above-mentioned time data and task count data, saves it in a file, edits the file, and adds time data to the conventional task trace data. The configuration is such that a trace file for all tasks is created and output with a task counter added.

This makes it possible to know the task page execution time and task counter together with conventional task trace data, making debugging easier.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

This is used to control DC loop closure, etc. The extension circuit 3 is a connection interface circuit provided for each extension, and serves as a connection interface between the exchange circuit 1 and each extension telephone. The control unit 4 also controls the operation of the switching circuit 1, as well as the extension telephone, etc.
It is in charge of controlling the entire system.

The main storage unit 5 is used to store various pieces of software necessary for controlling the exchange and various information necessary for its execution. It executes software and realizes the function as a switch. The external storage device 6 is a large-capacity storage device such as a magnetic disk device or an optical disk device that stores various files for storage. Further, a system clock 7 is provided inside the exchange and generates time information. The maintenance terminal 8 is a man-machine ψ interface that can communicate with the control section, and is an input/output device that can give data and commands to the control section and receive output data from the control section.

As shown in the functional block diagram of FIG. 2, the control unit 4 includes a task trace data collection means 41 for collecting trace data obtained when performing task tracing. A time data write means 43 that obtains and records the time data obtained from the collected trace data, a time data read means 42 that obtains time data from the system clock 7 and provides it to the time data write means 43, and a task in the task trace data. Counter clearing means 44 for clearing the counter section to "0"
, a count-up means 45 for incrementing a task counter section, and a trace data transmitting means 4B for transmitting collected trace data to the maintenance terminal 8. Also, as shown in the functional block diagram of FIG. 2, the maintenance terminal 8 also includes trace data receiving means 81. which receives trace data transmitted from the control unit 4. A trace data editing means 82 functions to edit trace data in response to an edit command operation input from a keyboard (not shown) in the maintenance terminal 8, and a trace data file section 83 files the trace data received by the trace data receiving means 81. , a task trace file 84, and a printing device 85 which is an external printer.

FIG. 3 shows an example of various files created according to the present invention. In the figure, (a) is an output example of the task trace file 84 that is finally created, and (b) is memory data (1B notation) indicating one unit of task trace data.
, (C) is data (ASCII code) indicating one unit of the trace data file 83 saved on the maintenance terminal 8 side.

The operation of this system as described above will be explained next. This system adds data called a task counter that manages information on the total number of executed tasks and time data that stores the execution time of tasks to conventional task trace data, obtains current time information every time a task page is executed, and In addition, the task counter is incremented each time a task is executed in the task page, and the time data and task count value collected thereby are sent to the maintenance terminal 8 along with conventional task trace data. The maintenance terminal 8 receives all the sent task trace data including the time data and task count value, saves it in a file, edits the file, and adds the time to the conventional task trace data. It is also Φ to have a configuration with a function to create and output a complete task trace file with added data and task counters.

Then, after collecting conventional task trace data when executing the task page, reading time data from the system clock 7 of the private branch exchange, converting the format of the time data,
Recorded in the specific data part of the task trace data. Next, the task counter part in the task trace data is cleared, and thereafter, the task counter part is counted up each time a task in the same task page is executed. Next, all the task trace data is transmitted to the maintenance terminal 8 using a transmitting means to which a function for transmitting a task counter section and a time data section is added. The maintenance terminal 8 receives all transmitted and received data using trace data receiving means, edits a trace data file using trace data editing means, and outputs it as a task trace file.

Although this is the case, its specific operation will be explained below.

FIG. 4 is a flowchart showing the procedure for collecting task trace data. When the control unit 4 receives a task trace command from the maintenance terminal 8, it is set to an operation mode in which the trace function is executed. Then, when the task page is activated by operating an extension phone, etc. (Sl)
, checks whether task trace data is currently being traced (S2). If it is determined in this step S2 that tracing is in progress, the process moves to step S3, and if it is determined that tracing has stopped, data collection is ended.

If it is determined in step S2 that tracing is in progress, the same task trace data as before is collected (s3).

That is, as data for each task page, terminal data for determining which terminal the task page acts on, the current state of the terminal, the address of the task page, etc. are collected.

Next, the time data read means 42 of the control unit 4 functions to synchronize the current time with the system clock 7 and read the time data (S4), and the time data write means 43 receives this and converts the time data into the task trace data. It is written in the time data section inside (S5). Next, clear the task counter part in the task trace data to "0" and initialize it (
S6). After that, when the task on the task page is activated (S7), the task counter is incremented (
1 count up) Shiku S8), then wait (Wai)
t) state (S9), and when the task is restarted, the task counter section in the task trace data is ink 1.
8 (count up by 1) (S7, S8). In this way, the task counter section is incremented each time one task is executed on the task page, and the total number of executed tasks is managed. Then, when a new task page is activated, the process returns to step Sl and data is collected as new task trace data.

FIG. 5 is a flowchart showing the procedure for editing and outputting the task trace data collected by the procedure shown in FIG. sends all task trace data (including time data and task counter count data) to maintenance terminal 8 (351
). In the maintenance terminal 8, the trace data receiving means 81 receives all the transmitted task trace data and stores it as a trace data file 83 as shown in FIG. 3(C) (852). Next, the trace data editing means 82 reads data for each task page from the trace data file 83 (853) (Please note that FIG.
), (b), and (c) show data for one task page), the conventional task trace file is edited and written to the task trace file 84 (S54).
).

Next, the trace data editing means 82 edits the time data section in the data read in step 853 and writes it to the task trace file 84 (855).Similarly, it edits the task counter section and writes it to the task trace file 84 (sse ) Through steps 953 to 95B, one task trace data for each task page shown in FIG. 3(a) is created.

Next, the trace data editing means 82 checks whether editing has been completed for all task page data in the trace data file 83 (857), and if it has not been completed, returns to step 853 and performs the above-described series of processing. Repeat.

When the editing is completed, the task trace file 84 is outputted to the printing device 85 according to the printer output format and printed (35g).

According to this embodiment as described above, the exchange has a conventional task trace function, task page execution time information, and a task count function that counts the total number of tasks actually executed in the task page to obtain data on the total number of executed tasks. In addition to providing functions, the configuration is such that these data can be sent to the maintenance terminal along with the trace data, and the maintenance terminal is configured to receive, edit, and output the sent data, so that, for example, When the task trace function has stopped due to the occurrence of a serious bug such as a system down, by referring to the task counter in the final task trace data, you can easily understand the task that the exchange executed just before the system went down. In addition, when a bug occurs on a customer site, by referring to the task page execution time, detailed information such as the operation of each terminal at the time the bug occurred can be easily retrieved from a huge amount of task trace data. This makes it possible to accurately understand information, which provides a major clue when analyzing bugs, and greatly improves debugging efficiency.

It should be noted that the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within the scope of the gist thereof.
