The invention discloses a method for keeping a checksum unchanged through general message feature data change and correction code calculation. An electric power device sends an original message mdr to a single communication device; the single communication device processes the original message to obtain a data message; the single communication device forwards the data message to the intermediate communication device; calculating to obtain a front-segment data checksum in the data message; based on the checksum of the front-segment data m in the data message, calculating to obtain the checksum of the front-segment data and the feature data in the data message; generating a correction code x1 through the checksum XOR of the front segment data and the feature data in the data message; and adding the correction code x1 into the data message and sending the data message to a network. According to the method, when the feature data of the intelligent substation communication equipment is increased ...

The invention discloses a method for realizing a shortest path high-reliability parallel redundant network (SPHPR) of communication equipment. The method comprises the following steps: adding feature data at the head of a source message through an access switch, wherein the message N (Ngt; 1 natural number) is sent, and a receiving end discards N-1 redundant data. A transformer substation network switch sends universal messages with feature data to N ports of a single-ring network at the same time, a receiving switch discards repeated late arrival messages, and message headers are analyzed through an agreed feature data format. And the substation network switch configures multicast address forwarding in a static mode, and discards messages which are not in a configuration range. A hot backup topology of star network core exchange between communication devices is configured by adopting an SPHPR principle, and parallel redundant hot backup of a core gigabit switch is realized by utilizing ...
