COM Debug Assistant is observed and is detected.
Currently, being often used following two mode to high-speed, large capacity serial data and with serial ports of computers baud rate not
Matched communication is observed and is detected.First way is that the data transmitted between high-speed serial ports are seen by oscillograph
It examines, the information content export of capture card, by original data record, is analyzed and examined afterwards using capture card by the second way
It looks into.
Currently, data are observed and detected using oscillograph and capture card acquisition data two ways, there are following
Problem.
First way is serial ports transmission high-speed, Large Volume Data to be observed by oscillograph, and oscillograph can only be right
Sampled data is observed in data time sequence and display screen in entire transmission process, can not be to certain partial words in transmission mass data
Section is exchanged or corrupt data is observed and detected, and it is highly difficult that mass data searches transmission corrupt data under high-speed transfer
, it is difficult to search problem in use and failure, brings fault detection inconvenient, causes to solve problem time slow.
The second way, by original data record, is afterwards analyzed the information content export of capture card using capture card
And inspection.Which can store mass data, however be unable to real-time perfoming observation and detection data failure, higher cost.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of fault detection means of communication data, original to solve
Detection inconvenience in communication data fault detection, the problem that real-time is not high, cost is larger.
In order to solve the above technical problems, the present invention provides a kind of fault detection means of communication data, including difference string
Mouth unit, Network Interface Unit, storage unit and power supply unit, wherein
The difference serial port unit is separately connected the Network Interface Unit and power supply unit, the difference serial port unit
The transmitting-receiving end data of difference serial ports is received, and differential signal is converted into TTL signal and is output to Network Interface Unit；
The Network Interface Unit is separately connected the difference serial port unit, storage unit and power supply unit, institute
It states Network Interface Unit reception serial data and is converted to network data and be then forwarded to the storage unit；
The storage unit shows the network data received, and for comparison data, analysis in real time with
And the accuracy of detection data；
Said supply unit is separately connected the difference serial port unit and Network Interface Unit, suitable for providing to it
Operating voltage.
Further, the difference serial port unit includes at least one group of differential signal input.
Further, the difference serial port unit is exported including at least TTL data all the way.
Further, the Network Interface Unit by received serial data be converted into network data by RJ45 interface it is straight
The storage unit is given in sending and receiving.
Compared with prior art, the fault detection means of a kind of communication data of the present invention, it is small in size, light-weight,
It has used the detection device to significantly improve accident analysis and detectability, has shortened trouble shooting time, real-time is high, detection
Capacity is big, improves efficiency for the debugging and maintenance of equipment, provides a kind of method of flexibly detection communication failure.
