[Conventional technology]

In an electronic switching network system consisting of one centralized station (hereinafter referred to as the master station) (!l: multiple monitored stations (hereinafter referred to as slave stations), the master station receives alarm signals from each slave station. At the same time, the content of the alarm signal, alarm occurrence time, station name, etc. are printed out using the attached printer.

In addition, in order to check the operating status of the slave stations under its control, the master station periodically keyed in the station name and test number to designate the station and check the normality of the slave station. In this way, the master station operates the system while capturing and monitoring the operating status of each slave station belonging to the electronic switching network system.

In the conventional test method, the tester uses the receiving device RE of the master station MATN.
Enter the slave station number and test number by operating the keys on the video display unit VDU provided in C. The microprocessor MPU stores the data necessary to execute the test of the input test number in the storage device MEM.
, and sends it to a predetermined slave station (
For example, 5UBo).

Alarm signal transfer device A built in slave station 5UBo
The L A RM receives the sent data indicating the test contents, performs the requested test, and returns the test results by the alarm signal transfer device A L A RM.

The receiving device REC inspects the test results returned from the slave station 5UBa and determines whether or not the slave station SUBa is normal.

[Problem that the invention seeks to solve]

Previously, the above operations were repeated to check the quality of each slave station one by one, but as the number of slave stations increases, the number of test items increases.
However, as the test content becomes more complex, it is very time consuming for testers to repeat the above operations manually, which is a major drawback in terms of maintenance.

The purpose of the present invention is to eliminate these drawbacks and provide an efficient and reliable test method.

[Means for solving problems]

To solve the problem, in an electronic switching network system consisting of - central stations and a plurality of monitored stations, the central stations are provided with a clock device, a storage device, and a control device, A test implementation schedule table, commands that instruct test contents, test data that should be taken by the monitored station during normal operation corresponding to each command, and an automatic test program are stored in the storage device, and an alarm is sent to each monitored station. The control device monitors the time output of the clock device according to the automatic test program, and performs the test at the specified time according to the instructions in the test schedule table. The command is sent to the monitored station, the monitored station receives the command using the alarm signal transfer device, performs the test specified by the command using the own station test function, and sends the test result data. an alarm transfer device for transmitting the alarm signal to the central station by the alarm signal transfer device, and for the control device to compare the received test result data with test data to be taken by the monitored station during normal conditions stored in the storage device; This is achieved using the following test method.

[Effect]

According to the present invention, a test schedule table, commands for instructing test contents, test data to be taken by the monitored station during normal operation in response to each command, and an automatic test program are stored in the storage device in the master station, The automatic test program works in conjunction with the clock device to perform the specified test on the specified slave station at the specified time, and reports the test data to the master station. Since the current slave station data and test data are compared to determine pass/fail, the tester's effort can be significantly reduced.

〔Example〕

FIG. 1 is a schematic diagram showing an embodiment of a test method for an alarm transfer device according to the present invention.

In the figure, RECa is a receiving device according to the present invention, and MEMa is an additional storage device.

The present invention will be described in detail below with reference to the drawings.

Create multiple commands that describe the contents of various tests to be performed on each slave station, and give each command a name. Furthermore, when the slave station is tested according to each command, data of the test results when the slave station is in a normal state is prepared. Next, a table is created that shows the names of commands to be executed at each time and the names of test logarithm slave stations.

The test implementation schedule table, command names, test contents of each command, and normal test data corresponding to each command are all stored in the additional storage device MEMa.

The microprocessor MPU reads the time output of the clock device WATC1, and when the time written in the table comes, reads from the table the name of the command to be executed at that time and the name of the slave station to be tested, and writes the name of the slave station to be tested from the table. The commands are sent to each slave station in sequence in the order specified by. Now, temporarily, it is a slave station SUB.

Suppose you send a command to .

The alarm signal transfer device AL A RM built in the slave station S U Bo receives the sent data indicating the test contents, performs the test requested by the own station test function, and transmits the alarm signal. This test result is returned by the transfer device AL ARM.

The receiving device RECa of the master station MATH is a slave station SUB. By comparing the test results returned from the slave station 5 with the test results when the slave station 5UBO is normal, which is stored in advance in the additional storage device MEMa in the receiver RECa, the slave station 5
Determine whether LIBo is normal.

If it is normal, perform the next test according to the instructions on the table, or if it is determined to be abnormal, issue an alarm and print out the test data on the attached printer PRT or on the video display. Output to Unisoto VDU.

Although the explanation of the improvement does not mention the alarm signal that is automatically transmitted from the slave station when an abnormality occurs in the slave station,
This signal can be received as usual.
