Description

TECHNICAL FIELD The present invention relates to a line test of various lines.

(Prior Art) There are currently two methods for conducting line tests on various lines. One is a method in which a tester goes to a station accommodating a test line and operates a test plug and a line test stand to perform a test. The other is a method in which a tester goes to a station accommodating a test line and operates a drop line test stand by a relay provided corresponding to the line without using a line drop test plug to perform a test.

(Problems to be Solved by the Invention) However, in order to perform a line test by any of the above-mentioned conventional methods, the tester must go to the station accommodating the test line and operate the test plug and the line test stand. There was a problem that it did not happen.

The present invention is for solving these problems, and it is possible to centralize maintenance, unmanned, and reduce operating costs by performing a line test by remote control without changing the conventional line test pull-in device. The purpose is to provide a remote control system for line testing.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a line test of a line test performed by a remote control, which is performed by a line test lead-in device accommodating lines such as subscriber lines and relay lines. In the remote control system, there are a remote test stand that is located away from the line test lead-in device and that sends instructions to perform a line test, and a line test that is located on the line test lead-in device and that is instructed by the remote test stand. Conduct the line test and send the result of the line test to the remote test stand, the test plug that connects this line test device and the desired line of the line test pull-in device, and the test plug of the line test pull-in device. It is characterized in that a robot for performing the attaching / detaching operation and a robot control device for controlling the operation of the robot are provided.

(Operation) According to the present invention having the above-described configuration, the tester specifies the line to be subjected to the line test from the remote test stand located far from the line test lead-in device side and gives an instruction such as the type of the line test. Send to the 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 the desired line of the line test pull-in device. The line test device performs a desired line test.

Therefore, the present invention can solve the above-mentioned problems, and can perform a line test by remote control while keeping the conventional line test lead-in device, etc., and can centralize maintenance, unmanned, and reduce operating cost. It is possible to provide a remote control method for line testing.

(Embodiment) An embodiment of the present invention will be described below with reference to 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 test apparatus 2 to be described later by a modem interface (not shown) to perform a line test from a place distant from a station accommodating a test line. There are a keyboard (not shown) for inputting commands for line pull-in, line test commands, and message input at the time of test, and a display (not shown) for displaying line signal monitor display, line status display, instruction of test contents, etc. Have. Reference numeral 2 denotes a line test device, which transfers a line number instructed from the remote test stand 1 to a robot control device 3 which will be described later, and sends an operation result on the side of the robot 4 which will be described later to the remote test stand 1 and a test plug 5 which will be described later. The type of the line drawn in by inserting is read, the line test instructed from the remote test stand 1 is performed, and the test result is transmitted to the remote test stand. Reference numeral 3 is a robot control device, which receives a designation of a test line from the line test device 2 and gives an instruction to the robot 4, and at the same time, outputs the operation result of the robot 4 to the line test device 2.
Send to. Reference numeral 4 denotes a robot, which receives a test line designation from the robot control device 3, attaches / detaches the test plug 5 to / from a target line, and transmits the result to the robot control device 3. Reference numeral 5 is a test plug, which is attached / detached by the robot 4 and is pulled into the line test apparatus 2 by a communication line (not shown) and a line type information line, which are connected when inserted. 6 is a line test pull-in device,
Various test lines are accommodated and line type information is jumpered for each line.

Next, the operation from the start to the end of the test in this embodiment will be described with reference to FIG.

The tester gives a command from the remote test stand 1 to pull in the test line. The command is remote test bench 1
From the line test device 2 via a modem line (not shown)
Data is transmitted to. Then, the line test device 2 transmits the data to the robot 4 via the robot control device 3. The robot 4 inserts the test plug 5 into the line test pull-in device 6 according to the received instruction. If the insertion is good, the robot 4 transmits the information of good insertion to the remote test stand 1 via the robot control device 3 and the line test device 2. The remote test stand 1 displays a line ready display on the screen of the display based on the received information. Next, the tester selects a line test menu from the remote test stand 1 and performs various tests. The contents of this test are transmitted to the line test device 2 and pulled in through the test plug 5 to test the line. When ending the test, the tester gives an end command from the remote test stand 1. This end command is transmitted from the remote test stand 1 to the line test apparatus 2 via a modem line (not shown). Then, the line test device 2 transmits the data to the robot 4 via the robot control device 3. The robot 4 removes the test plug 5 from the line test pull-in device 6 according to the received instruction, and returns to the home position. At the end of the test, the display of the remote test 1 becomes the initial screen.

(Effects of the Invention) As described above, according to the present invention, a tester does not go to a station accommodating a test line but can easily and efficiently conduct a line test from a place away from the station by using a personal computer. it can. Further, since remote control is possible, maintenance can be centralized and unmanned can be easily performed, and the operation cost can be reduced. Furthermore, since it can be easily configured externally to the conventional circuit test lead-in device, it is easy to introduce it with existing equipment.
