Example Embodiment
[0057] Example one
[0058] The portable power communication protocol detector of this embodiment is such as figure 1 with figure 2 As shown, it includes a collection device 1 and an analysis device 2 arranged in a handheld case. The acquisition device 1 contains a message listener and a parallel-to-serial processor; among them, the message listener is mirrored by the switch port, the signal message listener 4, the network signal message listener 5, and the serial signal message listener. The listener 6 and the MODEM carrier signal message listener 7 are composed of four message listeners, and the parallel-to-serial processor is composed of FPGA processor 3. The analysis device includes a CPU8, an analysis system 11, an input 9 and a display 10 respectively connected to the CPU8; among them, the CPU8 uses an embedded processor (model is MPC8377), and the input 9 uses a keyboard, mouse or touch screen input device, etc., the display 10Using general-purpose CRT or liquid crystal ...
Example Embodiment
[0086] Example two
[0087] The portable power communication protocol detector of this embodiment is basically the same as that of the first embodiment, except that the FPGA processor 3 is replaced by a plurality of single-chip computers that work together.
[0088] The detection method of this embodiment is slightly different from the first embodiment, except for the same steps:
[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 protocol through programming and performs grammatical and semantic analysis of the specific protocol. That is, there are multiple protocol analysis modules in the analysis system. The statutes are identified by different statute analysis modules,
[0091] 3. The loading protoco...
