Detailed description of the invention
For making the purpose of the embodiment of the present invention, technical scheme and advantage clearer, technical scheme in the embodiment of the present invention will be clearly and completely described below, obviously, described embodiment is a part of embodiment of the present invention rather than whole embodiments；Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of protection of the invention.
As shown in Figure 1, telegraphone monitoring alarm, including telephone circuit signal port 1, rectification circuit 2, power circuit 3, control circuit 4 and warning circuit 5, the input telegraphone of described telephone circuit signal port 1 is connected, described it is connected with the input of rectification circuit 2 with the outfan of telephone circuit signal port 1, the outfan of described rectification circuit 2 is connected with the input of control circuit 4, the outfan of described control circuit 4 is connected with warning circuit 5, and described power circuit 3 is connected with warning circuit 5.
Described rectification circuit 2 includes rectifier bridge F1, described rectifier bridge F1 is bridge rectifier bridge, for the AC signal in telephone circuit signal port 1 is converted into direct-current control voltage, power circuit 3 includes relay K V1 working power 6 and warning circuit working power 7, described control circuit 4 includes the first divider resistance R1, the second divider resistance R2, relay K V1 and audion Q1, described audion Q1 is switch triode, being used for controlling Guan Bi and the disconnection of relay K V1, described warning circuit 5 includes buzzer M1 and display lamp D1；
nullThe input of described rectifier bridge F1 is connected with telephone circuit signal port 1，The output plus terminal of rectifier bridge F1 and one end of the first divider resistance R1 are connected，The other end of the first divider resistance R1 respectively with one end of the second divider resistance R2、The base stage of audion Q1 is connected，The emitter stage of audion Q1 and the other end of the second divider resistance R2、Ground connection after the output negative terminal of rectifier bridge F1 is connected，The colelctor electrode of audion Q1 is connected with one end of the coil KV1.1 of relay K V1，The other end of coil KV1.1 is connected with relay K V1 working power 6，Warning circuit working power 7 is connected with one end of relay K V1 normally-closed contact KV1.2，It is connected with buzzer M1 after the other end concatenation display lamp D1 of relay K V1 normally-closed contact KV1.2，Relay K V1 normally opened contact KV1.3 is attempted by the two ends of relay K V1 normally-closed contact KV1.2.
