Embodiment Construction

[0036] Referring to accompanying drawing, the present invention a kind of locomotive signal equipment data recording method based on block chain technology, comprises the following steps:

[0037] Step 1. Select a railway bureau as the default node, and create a genesis block on the default node to initialize a new blockchain; the content of the genesis block is as follows figure 1 As shown, set the block ID to 0, set the block timestamp to the current time, set the previous block hash value PrevHash to 0, and set the current block hash value Hash to the hash calculation result of the block body content , the content of the block body is the remark information of the genesis block; configure the on-board equipment on each train as a light node data sending program through the configuration file; configure the data storage nodes of each railway bureau as full node mining through the configuration file program; configure the monitoring nodes of each railway bureau with a full-no...

Abstract

The invention provides a data recording method of a locomotive signal device based on a blockchain technology. The method includes a process including definition of a block data structure, configuration and connection of blockchain nodes, generation of block data, and recording of the data to a blockchain. After successful operation of the blockchain, all new block data can be browsed or historical block data can be inquired through a data full-node browser program of the locomotive signal device, and data content of data of the locomotive signal device is extracted through a block body and converted to a detailed state graph and a table mode of the locomotive signal device for display. The beneficial effects of the method are that the data of the locomotive signal device, generated by operation of a train, can be completely stored, the locomotive signal data is stored and recorded in a server of each railway administration in a blockchain mode, and the integrity and the security of the data can be guaranteed. No matter which line the train operates in, complete data records can be stored in each railway administration, data fragmentation and loss can be avoided, and the possibility that the data is tampered is fundamentally eliminated.

Description

technical field [0001] The invention relates to transmission control procedures, devices, equipment, circuits and systems, especially a data recording method for locomotive signal equipment based on block chain technology. Background technique [0002] Locomotive signal equipment, as an important equipment to ensure the safe operation of trains, is widely used in national railways. The locomotive signal equipment realizes the operation control of the train by receiving ground signals and train operation information. The data generated during train operation is collected by the locomotive signaling equipment and stored in the built-in memory of the locomotive signaling equipment. When the train enters and exits the warehouse for maintenance or failure, the operator boards the train to dump the data, and then downloads it to the computer for analysis. [0003] The current locomotive signal data dump method is too inefficient, it is not convenient for data dump and data analys...
