Abstract

PURPOSE:To shorten time for a wiring connection operation and a connection check by executing a continuity test between linear conductors connected by a connection pin by a pin inserting means and designating a matrix board in the next step after a continuity testing means finishes the continuity test. CONSTITUTION:A link is constituted by inserting the connection pin only to a required part out of cross points of respective matrix boards MB. Further, two check pins are inserted to a test position and the continuity test between those two pins is executed. For example, when the connection check is executed and a wiring board beam CM and a robot RM as the object of the check are instructed from a host station at first, only the primary MB is pulled out and fixed. In such a state, the pin is pulled out form the auxiliary area of the primary MB and inserted to test positions 1', 2' and 3'. In the state of inserting the pin to the test positions 1', 2' and 3', the continuity test is executed between the test positions 1' and 2'. Thus, the conductive state before and behind the cross point 3' can be confirmed.

Description

Description: TECHNICAL FIELD The present invention relates to a connection checking system, and more particularly to a connection checking system for a distribution board of an exchange.

Conventional technology Conventionally, the distribution board that connects the line cable on the subscriber side and the intra-office cable on the exchange side in an exchange has a structure in which each terminal group is arranged in a row, and connections are made by jumpering between them. It had been. In addition, the structure of the terminal group was soldered terminals, wrapped terminals, etc., so workers had to manually wire each wire one by one.
It had the disadvantage of poor workability.

In other words, the wiring work that connects the line cables on the subscriber side of conventional exchanges and the intra-office cables on the exchange side must be performed every time there is a change in subscribers, such as the installation or removal of new subscribers, and this work is done manually. Therefore, it had the disadvantage of poor workability. In addition, in an unmanned station, jumpering work for 1 to 2 f cattle per day requires time consuming work from the master station to go out and carry out the work, which has the disadvantage of being extremely inefficient.

OBJECTS OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and its object is to provide a connection check system that can shorten the time required for wiring connection operations and connection checks.

Structure of the Invention The connection check system according to the present invention is a connection check system that connects cross points on a matrix board in which linear conductors are arranged in a grid using connection pins, and performs a continuity test between the connected linear conductors. a specifying means for specifying a matrix board into which a connecting pin is to be inserted from among a plurality of matrix ports; a pin inserting means for inserting a connecting pin into a specified cross point on the matrix board; and the pin inserting means. a continuity test means for performing a continuity test between linear conductors connected by connection pins; and control for controlling the designation means to designate the next matrix board after the continuity test by the continuity test means is completed. It is characterized by having a means.

Example Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram showing the configuration of a connection check system according to the present invention.

In the figure, CM is a distribution frame to be connected and checked, MB is a matrix board, and LC is a link cable.The link cable LC connects each stage of matrix boards MB arranged in multiple stages to form a multi-stage link. Configure.

On the matrix board MB, wiring conductors are arranged in a grid pattern, and the intersections of the wiring conductors are generally called cross points. Also,
On the matrix board MB, there is an area where T-equipment pins are inserted at locations that do not constitute cross points. This area is called the T-(it area).Furthermore,
The location of the test crosspoint is called the test location. The above is shown in Figure 6, where S is the test position and E is the reserve area.

Further, a substrate on which four matrix boards as shown in FIG. 6 are wedged is a matrix board package (hereinafter referred to as MB-PKG). A plurality of M B-PKGs configured in this manner are set in the slots of the distribution board rack CM to constitute a distribution board. Then, a link is constructed by inserting connection pins only into necessary portions of the cross points on each matrix board MB.

Furthermore, by inserting two check pins into the test position, continuity testing between the two pins becomes possible.

Returning to FIG. 1, RM is a robot, and connections and checks are automated by this robot.

Further, RMC is a robot control unit, RMD is a robot drive unit, and RM B is a robot mechanism unit consisting of multiple axes, a hand unit, etc. In response to a control signal from the robot control unit RMC, the robot mechanism unit RMBO axis and The hunt section is driven to insert connection pins onto the matrix board MB and connect the links. Note that KB is an operating terminal.

Furthermore, FIG. 5 is a perspective view of the robot RM, and FIG. 2 is a plan view of the robot RM. The operation of inserting and removing pins into and out of the matrix board will be explained below using both figures.

As shown in FIG. 5, the robot RM has a motor that drives a hand part (not shown) that pulls out the matrix board in the Y2-axis direction, and a motor that drives the hand part (not shown) that pulls out the matrix board, and
A motor that drives the hand section in the Y1 axis direction and a hand section H
This includes a motor that drives the hand section H in the ZI-axis direction, and a motor that drives the hand section H in the X2-axis direction. Further, it is configured to include a motor that drives the entire portion mentioned above in the Xl-axis and Z2-axis directions, and a motor that drives the matrix board in the X3-axis direction.

The above-mentioned motors control the drawer/X-end section (not shown) to first move in the XI-axis direction and the 22-axis direction and stop at the drawer position of the matrix board to be drawn out. Next, the matrix board is pulled out in the Y2-axis direction and set, and then moved in the X3-axis direction to perform @adjustment. Then, after controlling the movement of the hand part H in the YI-axis direction and the Zl-axis direction and stopping at the pin insertion or withdrawal position, the hand part H is moved in the X2-axis direction, and the pin is inserted or withdrawn using the chuck. It is.

FIG. 2 is a view of the robot RM performing the above-mentioned operations as seen from the direction of arrow B. In the same figure (a), first, M B
-Move the hand part H2 of the robot RM to the position to pull out the PKG, pull out the M B -PKG in the Y2 axis direction, and set it at the position indicated by the broken line. MB pulled out and set
-PKG is one of the four target matrix MBs
MB positioning is performed by inserting a positioning pin into only one of the two. After positioning is completed, the pin insertion/extraction operation begins.

Positioning during pin insertion/extraction operation is in the YI axis direction of the robot.
It is moved in the Zl axis direction (see FIG. 5) to the pin hole position on the matrix board MB, and further moved in the X3 axis direction to the insertion/extraction pin hole position on the MB.

Note that the movement information in this case is determined based on data from the higher-level device.

After positioning at the insertion/extraction position, the chuck section C inserts/extracts the pin by moving the hand section H in the X2 axis direction. In this case, the movement in the X2 axis direction is performed at low speed when moving toward the matrix board MB to remove the pin and when inserting the pin, and moves away from the matrix board MB when removing the pin and after completing the pin insertion. Sometimes it is controlled to operate at medium speed.

In addition, the chuck part C of the hand part H is driven and controlled by the motor drive part M so as to move the claw parts T1 and T2 in the Y3-axis direction to sandwich the pin P, as shown in FIG. 3(b). . By this movement in the Y3-axis direction and the above-mentioned movement in the X2-axis direction, the pin P is inserted into and removed from the matrix board MB.

Next, an example of a connection check and the pin insertion/extraction operation at that time will be explained using FIGS. 3 and 4.

FIG. 3 is a flowchart showing a connection check procedure by the system of this embodiment, and FIG. 4 is a schematic diagram showing pin insertion/extraction positions during that procedure. Both figures show the procedure for checking the connection of a three-stage link.
■, ■, etc. in FIGS. 3(a) and 3(b) represent movements to the positions indicated by the same symbols in FIG. 4. Further, in FIG. 4, TE is a continuity test circuit. In addition, in FIG. 4, the symbol ◯ indicates a connection pin, and the symbol ◯ indicates a check pin.

In Fig. 3, when checking the connections using this system, the first step is to check the distribution frame C.
When an instruction is given to the RM from a host device, such as a master station (step 31), only the first stage (primary M B ) of the corresponding matrix board is pulled out and fixed (step 32).

In this state, the pin is removed from the spare area of the primary MB and inserted into the test position (3) in FIG. 4 (step 33). Also,
-r- (Remove the pin from the Q area and test position in Figure 4 ■
(step 34). Furthermore, a pin is pulled out from the spare area and inserted into the cross point (3) in FIG. 4 (step 35).

With the pins inserted in the test positions ■ and ■ and the cross point ■, a continuity test is performed between the test position ■ and the trial test position (step 36). This allows you to check whether there is continuity before or after the cross point (2).

After the continuity test, remove the pin at the test position ■ (step 37)
, the primary MB is released from its fixation and returned to its original position while the hand part is holding the pin (step 38). continue,
Only the second stage (secondary MB) of the matrix boards is pulled out and fixed (step 39). In this state, the pin currently held by the hand section is inserted into the test position (3) in FIG. 4 (step 40). Further, a pin is pulled out from the spare area and inserted into the cross point (2) in FIG. 4 (step 41).

A continuity test between the test position ■ and the wiping position ■ is performed with the pins inserted into the test positions ■ and ■ and the cross points ■ and ■ (step 42). With this, it is possible to check whether there is continuity before or after the cross points (■) to (■).

After the continuity test, pull out the pin at the test position ■ (Stennob 43)
, the hand part releases the fixation of the secondary MB and returns it to its original position while holding the pin (step 44). Subsequently, only the third stage (tertiary MB) of the matrix boards is pulled out and fixed (step 45). In this state, the pin currently held by the hand section is inserted into the test position (3) in FIG. 4 (step 46). Also, remove the pin from the spare area and insert it into the cross point ■ in Figure 4 (Step 4
7).

A continuity test is performed between the test positions ■ and ■ with the pins inserted at the test positions ■ and ■ and the cross points ■, ■, and ■ (step 48).

This makes it possible to check the conduction state before and after the cross points (1) to (2), that is, the entire link.

The continuity test is now complete, but the test pin must be removed from the test position and returned to the reserve area. Therefore, after the continuity test, the pin at the test position (3) is removed (step 49), and the tertiary MB is released from the fixation and returned to its original position while the hand part is holding the pin (step 50). Subsequently, only the first stage (primary MB) of the matrix boards is pulled out and fixed (step 51).

In this state, insert the pin currently held by the hand into the spare area on the MBI (step 52), and remove the pin at test position ■ and insert it into the spare area (step 5).
3). Then, the fixation of the primary MB is released and returned to the original position (step 54). This completes the check operation, and a termination message is sent (step 55), completing the process (step 56).

As described above, according to the present invention, the matrix board connection check can be automated. Furthermore, if a terminal or the like for operating this system is provided in the master station, it is possible to easily change and check connections of slave stations located in remote locations.

Although the present embodiment has been described with reference to three matrix boards, that is, twice the number of three-stage links, it is clear that connection changes and checks can be made in the same way for even more multi-stage links.

Also, there may be cases where a link is configured using all four matrix boards in the same MB-PKG, but it is clear that connection changes and checks can be made in the same way even in such cases. .

DETAILED DESCRIPTION OF THE INVENTION As described above, in the present invention, after pulling out the M B-PKG and inserting a check pin into the robot's hand, the pin is inserted and removed at the cross point of the stage, and after a continuity test, the robot's hand Pull out the check pin, push back the MB-PKG while holding the check pin, then pull out the next stage MB-PKG and insert the check pin, then insert and remove the next stage cross point, After the continuity test, the robot hand performs a series of operations on the multi-stage link, such as pulling out the check pin.
This has the effect of shortening the time for connection and checking.
