An embodiment of the utility model provides a novel portable remote signalling message parsing shows device, include: the device body, network interface module, protocol converter, analytic circuit and display screen, the staff can directly be connected with the equipment in the transformer substation analyzing display device, receiving equipment's remote signalling message information, and carry out protocol conversion through protocol converter to the remote signalling message information, analyze the remote signalling message information through analytic circuit, to analyze the result through the display screen that installs the configuration shows, operation process is very simple, need not remote signalling message information forwardding and transmitting through a plurality of nodes, can accomplish remote signalling debugging and examination work through such equipment at the station side of factory, work flow has been simplified, the pollution to data of loaded down with trivial details transmission process has been avoided. Can realize synchronous examination of main website and factory station remote signalling data, shorten operating time, improve the work efficiency that the remote signalling was checked and accepted.
