1. the utility model has been realized wired voice communication, has improved voice communication quality, has guaranteed accuracy and reliability to line; Do not need to join speech ciphering equipment in addition, reduced cost.
2. the utility model has improved the lineman has been made efficient.Utilize CPU once can finish many cables the lineman is done automatically.
3. the utility model has made things convenient for the line operation, reduces the line operating personnel.This is finished line automatically to the line assistor, afterwards, changes voice communication automatically over to, carries out the cable numbering and checks, and 2 people can finish line is operated.
Description of drawings
Fig. 1 is that the secondary circuit of embodiment 1 is to line assistor electrical block diagram.
Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
Fig. 1 is a secondary circuit to line assistor (being called for short the line assistor) schematic diagram, and the line assistor is made up of main frame and handset.S is an electronic switch, and by CPU control, VD is an optocoupler, and its output signal is sent CPU; Line assistor main frame, handset all are provided with voice communication, liquid-crystal display section.
The secondary circuit of present embodiment comprises main frame and handset to the line assistor, 14 terminals of main frame respectively with 14 corresponding joining of terminals of cable one end, 14 terminals of handset respectively with 14 corresponding joining of terminals of the cable other end.
14 terminal D01-D14 of main frame join with the negative pole of the diode of 14 optocoupler VD301-VD314 respectively, the positive pole of the diode of k optocoupler is received k-1 the terminal (corresponding S302-S314) of main frame through the k electronic switch, 2≤k≤N, the positive pole of the diode of the 1st optocoupler receive the 2nd terminal of main frame through the 1st electronic switch S301; Two terminals of main frame speech transmission device meet the 1st terminal D01 and the 2nd terminal D02 (also can be to take over two terminals of meaning) of main frame respectively through 2 voice transfer electronic switch S315 and S316, are to connect the 1st and the 2nd terminal in this example; The output terminal of 14 optocouplers all joins with the detection terminal of host microprocessors;
