Description

A kind of communication equipment fault identification device

Technical field

This utility model relates to communication technique field, particularly to a kind of communication equipment fault identification device.

Background technology

Electrical fire monitoring device is the terminal control part that electric leakage signal processes, the signal passed over scene by upper software carries out intellectual analysis process, judge the state (i.e. malfunction, fire alarm state, normal operating conditions) of each current probe, scent a hidden danger position in time, reduces the generation of electrical fire；And the bridge that communication equipment is often worked hard in glove with as electrical fire monitoring device and detector, the quality of its duty decides fire hazard monitoring signal, the accuracy of instruction transmission, reliability.The short circuit of existing communication equipment and open circuit type are difficult to correctly distinguish, and are simply classified as a class simply, it is impossible to thoroughly distinguish, thus cause communication data distortion, the generation of misinformation accident and cannot understand the Real-time and Dynamic situation of communication equipment in time.

Utility model content

Therefore, for above-mentioned problem, the utility model proposes a kind of communication equipment fault identification device that can effectively identify short circuit and the open circuit fault type judging communication equipment.

For solving this technical problem, this utility model takes below scheme: a kind of communication equipment fault identification device, including single-chip microcomputer, oneth 6N137 photo-coupler and the 2nd 6N137 photo-coupler, a described 6N137 photo-coupler input is connected with the communication interface of communication equipment, a described 6N137 optocoupler output communicates to connect with the first communication serial port of single-chip microcomputer, described 2nd 6N137 photo-coupler input communicates to connect with the second communication serial port of single-chip microcomputer, the outfan of described 2nd 6N137 photo-coupler communication interface with a 6N137 photo-coupler input and communication equipment respectively is connected.

Further improving, also include failure indicating circuit and sound warning circuit, this failure indicating circuit is all connected with the outfan of single-chip microcomputer with sound warning circuit.

Further improving, described failure indicating circuit includes the LED light that two-way is in parallel.

nullBy using preceding solution，The beneficial effects of the utility model are: by utilizing a 6N137 photo-coupler and the 2nd 6N137 photo-coupler forming an isolation circuit between single-chip microcomputer and the communication of external communication device，It is responsible for communication by a 6N137 photo-coupler，Detection is responsible for by 2nd 6N137 photo-coupler，When the first communication serial port communication of single-chip microcomputer is normal，So circuit of external communication device is in normal condition，When the first communication serial port of single-chip microcomputer can not receive signal，Then single-chip microcomputer sends a signal to a 6N137 photo-coupler by the second communication serial port warp and the 2nd 6N137 photo-coupler，Now the first communication serial port such as single-chip microcomputer can not receive signal，The then line short of external communication device，As single-chip microcomputer the first communication serial port receives the signal of the second communication serial port，The then line broken circuit of external communication device，So that single-chip microcomputer can accurately judge short circuit or the open circuit fault of external communication device，Correct differentiation short circuit and open circuit type，Reduce communication data distortion、The generation of misinformation accident，Understand the Real-time and Dynamic situation of communication equipment in time；By further arranging, i.e. failure indicating circuit and the setting of sound warning circuit so that single-chip microcomputer can show and the malfunction of audible alarm instruction current communication devices intuitively.
