Abstract

PURPOSE:To apply line test remotely without visiting a station accommodating a test line by using a robot operated by a remote signal so as to control the connection of a test plug of a drawing device for a line to be tested. CONSTITUTION:A test personnel transmits a command such as designation of a line and kinds oil line test to conduct the line test from a remote test board 1 at a remote location from the line test drawing device 6 to a line test device 2. The line test device 2 supplies the command to be received to a robot controller 3, which controls the robot 4 in a way of a test plug 5 is inserted to a desired line of the line test drawing device based on the command. Then the line test device 6 applies a desired line test. Thus, the line is tested by remote control to attain unattended maintenance, centralization of maintenance and reduction in the operation cost.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to line testing of various lines.

(Prior Art) There are currently two methods for performing line tests on various lines. One method is for the tester to go to the station that accommodates the test line and operate the test plug and line test stand to perform the test. The other method is for the tester to go to the station where the test line is housed and conduct the test by operating the lead-in line test stand using a relay installed for the line, instead of using a test plug to connect the line.

(Problems to be Solved by the Invention) However, in order to perform a line test using any of the conventional methods described above, the tester must go to the station that accommodates the test line and operate the test plug and line test stand. The problem is that it has to be done.

The present invention is intended to solve these problems, and has the advantage of being able to remotely control line tests without using conventional line test lead-in equipment, etc., centralizing maintenance, making it unmanned, and reducing operating costs. The purpose is to provide a remote control method for line testing.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a system for remotely controlling a line test performed by a line test lead-in device that accommodates lines such as subscriber lines and trunk lines. In the remote control method, there is a remote test stand that is located away from the line test lead-in equipment and sends instructions for conducting a line test, and a remote test stand that is located on the line test lead-in equipment and that receives instructions from the remote test stand. A line test device that performs a test and sends the line test results to a remote test stand, a test plug that connects this line test device and the desired line of the line test lead-in device, and a test plug that connects the line test device to the desired line of the line test lead-in device, and a The present invention is characterized by the provision of a robot that attaches and detaches the plug, and a robot control device that controls the operation of this robot.

(Function) According to the present invention having the above-described configuration, the tester can specify the line to be tested, the type of line test, etc. from a remote test stand located away from the line test lead-in device. Send to line test equipment. Further, the line test device supplies the received instruction to the robot control device, and based on this instruction, the robot control device controls the robot to insert the test plug into a desired line of the line test lead-in device. The line test equipment performs a desired line test.

Therefore, the present invention is able to solve the above-mentioned problems, and is advantageous in that it allows line tests to be remotely controlled without changing the conventional line test lead-in equipment, etc., thereby centralizing maintenance, making it unmanned, and reducing operating costs. It is possible to provide a remote control method for line testing.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a block diagram showing the system configuration of an embodiment of the present invention. In the figure, reference numeral 1 denotes a remote test stand, which is connected to a line testing device 2 (described later) via a modem interface (not shown), and is used to conduct line tests from a location away from the station where the test line is accommodated. A keyboard (not shown) is used to enter commands for connecting the line, line test commands, and messages during testing, and a display (not shown) is used to display line signal monitors, line status displays, test content instructions, etc. have Reference numeral 2 denotes a line test device that transfers the line number instructed from the remote test stand 1 to the robot control device 3 (described later), and also transmits the operation results on the robot 4 side (described later) to the remote test bench 1, and transmits a test plug 5 (described later). The remote test stand 1 reads the type of line that has been drawn in by inserting the , performs the instructed line test, and transmits the test results to the remote test stand. A robot control device 3 instructs the robot 4 upon receiving the designation of the test line from the line testing device 2 and transmits the operation results of the robot 4 to the line testing device 2. 4 is a robot which, upon receiving the test line designation from the robot control device 3, attaches and detaches the test plug 5 to the specified line [1] and transmits the results to the robot control device 3. Reference numeral 5 denotes a test plug, which is attached and detached by the robot 4, and is connected to the line testing device 2 by a communication line and a line type information line (not shown) that are connected when the plug is inserted. 6 is the line test lead-in device,
Various test lines are accommodated, and line type information is provided with jumpers for each line.

Next, the operation from the start to the end of the test in this embodiment will be explained using FIG.

The tester issues a command to connect the test line from the remote test stand 1. The command is remote test bench l
to line test equipment 2 via a modem line (not shown).
data is transmitted to. Then, in the line testing device 2, it is transmitted to the robot 4 via the robot control device 3. The robot 4 inserts the test plug 5 into the line test lead-in device 6 according to the received instructions. If the insertion is successful, the robot 4 transmits information indicating that the insertion is successful to the remote test stand 1 via the robot control device 3 and the line testing device 2. Based on the received information, the remote test bench 1 displays a message indicating that the line preparation is complete on the display screen. Next, the tester selects a line test menu from the remote test stand 1 and performs various tests. The content of this test is data transmitted to the line testing device 2, and is drawn in via the test plug 5 to test the line. To end the test, the tester issues an end command from the remote test bench 1. This termination command is data transmitted from the remote test bench 1 to the line testing device 2 via a modem line (not shown). The line testing device 2 then transmits the signal to the robot 4 via the robot control device 3. The robot 4 pulls out the test plug 5 from the line test pull-in device 6 according to the received instruction and returns to its home position. At the end of the test, the display of the remote test stand 1 becomes the initial screen.

(Effects of the Invention) As explained above, according to the present invention, a tester can easily and efficiently test a line using a personal computer from a distance from the station without going to the station where the test line is accommodated. can. Furthermore, since remote control is possible, maintenance can be easily centralized and unmanned, and operational costs can be reduced. Furthermore, since it can be easily configured by externally attaching it to a conventional line test lead-in device, it is easy to install it with existing equipment.
