As shown in fig. 1: a flow chart of a method of storing underground structure state information for a blockchain of the present invention; the flow chart comprises the following steps: step S100, acquiring the safety information range of each building structure, and storing the safety information range in a block chain head block; step S101, the block chain carries out data analysis processing on the received structural state information; step S102, the structural state information is divided into original data and processed data and stored in a block of a block chain; step S103, comparing whether the mercker root value of the mercker tree of the processed data synthesis in the new block is the same as the mercker root value of the mercker tree of the data synthesis processed in the safety status information range, and if not, verifying that the new block has abnormal information.
Specifically, the method comprises the following steps of carrying out data analysis processing on the obtained building state data: according to whether the state information data is in the safety information range of the building structure, if so, converting the structure state information into data which is the same as the structure safety information range converted in the first block; if not, converting the structure state information into data with a different structure safety information range from that of the first block; and then comparing whether the Mercker root values formed by the converted data in the new block and the first block are the same or not, if the Mercker root values are different, proving that the data in the new block is abnormal, locking the equipment number corresponding to the abnormal state information, sending early warning information to the equipment, and sending warning information to the warning equipment by the equipment for warning.
In the above embodiment, in step S100, the safety information range of each building structure is obtained, and the safety information range is stored in the head block of the block chain; specifically, firstly, the safety information range is accurately calculated according to different building structures at the monitoring part, and comprises the inclination angle range, the height, the stability of a connecting point and the like of the building structure; the obtained safety information range is composed of the equipment number and the safety information range data which are extracted from the safety information range, then the received safety information ranges transmitted by all the equipment are processed, and each safety information range is converted into the equipment number and the safety information range data i Form (b) wherein X i May be the same or different; and after conversion, packaging all the original data of the safety information range and the processed data of the safety information range respectively.
The above embodiments further include the formation of a block chain; and after the data conversion of all the building structure safety information ranges is completed, activating the system to generate a first block of the block chain, and writing the packed safety information range original data and the processed safety information range data into the block chain respectively according to a certain sequence.
Preferably, the above sorting manner for writing the block chains respectively according to a certain sequence is: numbering all equipment numbers from 1 to n, wherein the equipment number numbers correspond to the data in the safety information range of the building structure; and storing the data written into the safety information range of the building structure of the block chain Merckel tree into the first block from 1 to n according to the corresponding equipment number sequence.
Step S101, the block chain carries out data analysis processing on the received structural state information; specifically, besides the conversion of the building structure safety information of the first block, the method also comprises the step of performing data analysis processing on the structure state information to be written into other blocks on the block chain.
Preferably, the method for analyzing and processing data of the structural state information of other blocks in the block chain comprises: according to the equipment number, acquiring the safety information range of the building structure in the first block, including the original data of the safety information range of the building structure: the device number + safety information range data, and the corresponding data after the conversion are processed: device number + X i (ii) a Judging whether the structural state information corresponding to the building structure is in the safety information range corresponding to the building structure, if so, proving that the state information stored in the block is abnormal, and converting the structural state information into the information equipment number + X which is the same as the first block i (ii) a If not, the state information stored in the block is proved to have abnormal information, and the structural state information is converted into the information equipment number + Y different from the first block i 。
