BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for locating a printed circuit board (PCB) of an electronic switching device, and in particular, to mounting a plurality of matching boards randomly. A positioning device.

In this regard, FIG. 1 is a schematic diagram showing an embodiment of a general printed circuit board mounting in conjunction with an all-electronic exchanger, and a control board for controlling a plurality of first, second, and n-th matching boards 12, 14, and 16. FIG. It consists of 10.

The operation of the general printed circuit board mounted as described above is as follows.

In the electronic switching system, one control board 10 controls a plurality of first, second, and n-th matching boards 12, 14, and 16, and in particular, a plurality of first, second, and first Each of the n-matching boards 12, 14, and 16 has a control address and is controlled by the control board 10.

However, in such a conventional technology, the control board 10 includes a plurality of first, second, and first products unless the plurality of first, second, and n-th matching boards 12, 14, and 16 are mounted at predetermined positions. Since the positions of the n-matching boards 12, 14, and 16 are unknown, there are inconveniences in that a plurality of first, second, and n-th matching boards 12, 14, and 16 must be mounted at a predetermined position.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the prior art, and has a printed circuit board mounting position checking apparatus for an electronic exchanger that can check the position of each matching board even when a plurality of matching boards are mounted at random. The purpose is to provide.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention for achieving the above object is as follows.

Referring to FIG. 2, FIG. 2 is a block diagram showing an embodiment of a printed circuit board mounting position checking apparatus of an all-electronic exchanger according to the present invention, which is commonly connected to the control data exchange communication path and is a control data exchange communication path. And a plurality of first, second, and n-th matching boards 22, 24, and 26 for outputting their own mounting position signals when the control signal for checking the mounting position is received through the control signal for checking the mounting position thereof. And a plurality of first, second, and n-th matching boards 22, 24, and 26, connected to the control data exchange communication path, to output a control signal for confirming the mounting position of the desired matching board through the control data exchange communication path. The control board 20 is configured to check the mounting position of the plurality of first, second, and n-th matching boards 22, 24, and 26 by receiving the corresponding mounting position signal.

In this case, the control board 20 is a program for a function of sequentially checking the slot positions of the plurality of first, second, n-th matching boards 22, 24, 26 by receiving a plurality of slot position signals in sequence. Matching the communication port to provide a data exchange communication path capable of transmitting and receiving in the HDLC mode with the storage unit 220 storing the (Program) and the plurality of first, second, n-th matching board (22, 24, 26) The slot 240 and the slot position signal latch unit 210 for reading the information for detecting and analyzing the slot position signal when the matching board receiving the slot position signal driving command through the data exchange communication path drives the slot position signal. And a central processing unit (CPU) 230 for controlling the operation of the slot position signal latch unit 210, the communication port matching unit 240, and the storage unit 220.

The present invention made in this way is described in detail as follows.

First, the plurality of first, second, and n-th matching boards 22, 24, and 26 each perform a predetermined matching function, and are commonly connected to the control data exchange communication path to be mounted from the control board 20. When the control signal for confirmation is received through the control data exchange communication path and the control signal for checking the own mounting position, it outputs its own mounting position signal.

That is, the plurality of first, second, and n-th matching boards 22, 24, and 26 may be arranged in order only for ease of explanation, and may be determined in a different order, and the mounting position signal of the first matching board 22 may be The slot 1 signal and the mounting position signal of the second matching board 24 are slot 2 signals, and the mounting position signal of the nth matching board 22 is the slot n signal.

Next, the control board 20 is connected to the control data exchange communication path, and outputs a control signal for confirming the mounting position of the desired registration board through the control data exchange communication path, thereby matching the plurality of first, second, and n-th matches. The mounting position signals are applied from the boards 22, 24, and 26 to check the mounting positions of the plurality of first, second, and n-th matching boards 22, 24, and 26.

In this case, each of the plurality of first, second, and n-th matching boards 22, 24, and 26 receives a control signal for confirming the mounting position from the control board 20 through a control data exchange communication path and mounts itself. It outputs its own mounting position signal only when it is a control signal for positioning.

In addition, the storage unit 220 of the control board 20 receives a plurality of slot position signal slot 1 signals and slot n signals in sequence, thereby providing a plurality of first, second, and n-th matching boards 22, 24, and 26. Stores a program for the function of sequentially checking the slot position, the communication port matching unit 240 is capable of transmitting and receiving in a HDLC mode with a plurality of first, second, n-th matching boards (22, 24, 26) Provide a data exchange communication path.

Next, the slot position signal latch unit 210 detects and analyzes information when the matching board receiving the slot position signal driving command through the data exchange communication path drives the slot position signal, and analyzes the information for the storage unit 220 and the center. The processor 230 may read the CPU 230, and the CPU 230 may control operations of the slot position signal latch 210, the communication port matcher 240, and the storage 220.

As described above, according to the present invention, even when a plurality of matching boards are mounted at random, it is possible to check the position of each matching board, thereby making it very easy to mount the matching board.
