Problems solved by technology

[0008] 2) Some modules described in the device (such as CAN network access module, LONWORK module, etc.) only have general terms, without relevant circuit diagrams and implementation mechanisms, and do not know what the specific structure is, and those skilled in the art cannot rely on the patent file for production
[0009] 3) The device is a split-type fixed device, and multiple sets need to be arranged in the comprehensive automation system of each transmission and substation, which is costly and inconvenient to move and carry
[0010] 4) The device first records and stores each message, and then consults the stored historical message records to analyze the cause of the message failure after a fault occurs. It cannot analyze the message online in real time, and it is difficult to quickly and timely discover the hidden dangers of the accident. Network communication failure and find out the cause of the failure, so that it does nothing to eliminate and avoid the expansion of the real-time power grid failure caused by the hidden network communication failure
[0011] 5) The description of the analysis method described by the analysis management machine of the device is vague and unclear. The analysis method "analyzes the message according to the byte and byte combination sequence according to the protocol, and then analyzes the information between the message and the message according to the protocol. Analysis of relationship", very incomplete, no relationship between bytes and bytes or byte combinations, byte branches, etc.; no environmental correlation analysis, protocol compliance analysis, etc.
Most of its content is the object of analysis and the result of analysis, and it is difficult for those skilled in the art to effectively analyze the recorded messages according to this analysis method

Embodiment 1

[0058] The portable power communication protocol detector of this embodiment is as figure 1 and figure 2 As shown, it includes an acquisition device 1 and an analysis device 2 arranged in a hand-held case. Acquisition device 1 contains message listener and parallel-to-serial processor; Listener 6 and MODEM carrier signal message listener 7 are composed of four message listeners, and the parallel-to-serial processor is composed of FPGA processor 3. Analysis device contains CPU8, analysis system 11, input device 9 and display 10 connected with CPU8 respectively; Wherein, CPU8 adopts embedded processor (model is MPC8377), input device 9 adopts keyboard, mouse or touch screen input device etc., display 10 adopt general CRT or liquid crystal display. The respective input terminals of the above four message listeners are respectively connected to the exchange communication link 13, the network communication link 14, the serial port power communication link 15 and the carrier pow...

Embodiment 2

[0087] The portable power communication protocol detector of this embodiment is basically the same as that of Embodiment 1, the difference is that the FPGA processor 3 is replaced by a plurality of single-chip microcomputers working together.

[0088] The detection method of the present embodiment is slightly different from the first embodiment, and the difference except the same steps is:

[0089] 1. The specific association designation in step 1) is to select the protocol analysis module 19 corresponding to the specific protocol of the power communication link to be detected;

[0090] 2. The protocol analysis module 19 in step 2 is a non-universal module that forms the grammatical and semantic environment of a specific statute through program design and performs grammatical and semantic analysis on a specific statute, that is, there are multiple statute analysis modules inside the analysis system, different The specifications of are identified by different specification anal...

Abstract

The invention relates to a portable electric power communication protocol detector, simultaneously relates to a detection method of the detector and belongs to the technical field of communication detection in electric power systems. The detector comprises an acquisition device positioned in a portable machine case and in which includes a massage listener and a parallel to serial processor, and an analytic device containing a CPU, an analytic system, an input unit and a display, wherein the input unit and the display are respectively connected with the CPU. The input end of the massage listener is accessed into an electric power communication chain, and the output end of the massage listener is connected to the input end of the parallel to serial processor in parallel; the output end of the parallel to serial processor is connected with the CPU in series; and the control ends of the massage listener and the parallel to serial processor are respectively connected with the CPU. The detection method comprises the following steps: initializing the analytic system after parameters and system files of the detector are configured and then obtaining and displaying analysis results after the listened massage of the electric power communication chain is subjected to real-time network analysis and protocol analysis. The invention can eliminate the massage loss caused during the detectionof electric power communication, thereby truly and effectively detecting the electric power communication.

Description

technical field [0001] The invention relates to an instrument for real-time detection of power system communication and its process, as well as a detection method of the detector, belonging to the technical field of power system communication detection. Background technique [0002] The current power system has generally adopted automation systems for monitoring, control and scheduling, such as energy management system EMS, substation integrated automation system SCADA, etc. The information source and control of these systems all rely on network communication, and with the implementation and large-scale promotion of digital substations based on the IEC61850 communication system, the traditional control connection of measuring, controlling, measuring current and voltage, circuit breakers and isolating switches through cable connections Blocking, relay protection tripping and closing, starting, blocking and other signals have also been changed to realize through network commun...
