Monitoring device for point-to-point communication equipment and monitoring system having same

Abstract

The invention provides a monitoring device of point-to-point communication equipment and a monitoring system having the monitoring device of the point-to-point communication equipment. The device comprises a first equipment interface which is connected with the communication interface of first communication equipment; a second equipment interface which is connected with the first equipment interface and the communication interface of second communication equipment; a data sampling module which samples the communication data between the first equipment interface and the second equipment interface; a data processing module which is connected with the data sampling module and processes the sampled communication data according to a preset communication protocol; and a communication module which is connected with the data processing module and external monitoring equipment and outputs the processed communication data to the monitoring equipment. The communication data of both sides of the point-to-point communication equipment are monitored through hardware and the monitored communication data are outputted so that modification of the software level and / or the hardware level can be avoided, the change of the communication data of the hardware level can be monitored and thus onsite debugging of the point-to-point communication equipment can be greatly facilitated.

Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a monitoring device and a monitoring system of point-to-point communication equipment. Background technique

[0002] Point-to-point serial communication is a communication method often used in the industry. Usually, there is no master-slave concept between the two parties in point-to-point serial communication, that is, the two parties in communication are in an equal relationship, or point-to-point serial communication is one master and many Slave device (the one-master multi-slave device cannot add a monitoring slave device that can receive all the information on the bus). Frequently used point-to-point serial communication devices include RS232 (Asynchronous Transmission Standard Interface), SPI (SerialPeripheral Interface, Serial Peripheral Interface) and IIC (Integrated Circuit Bus, Inter-Integrated Circuit) and so on. The point-to-point serial communication equipment...
