Relay protection device management and control method and system based on block chain technology

The invention belongs to the field of relay protection device management and control, and provides a relay protection device management and control method and system based on a block chain technology. The relay protection device management and control method based on the block chain technology comprises the following steps: encrypting a constant value template file to establish a one-to-one correspondence relationship between the constant value template file and a protection device; when the encrypted constant value template file is stored locally, the encrypted constant value template file is uploaded to a regulation and control cloud platform through a secondary equipment online monitoring master station, and the file is stored in a block chain server after consistency checking of the file; and encrypting a complete constant value file generated after setting calculation, submitting the encrypted constant value file to a block chain server for storage, and issuing the encrypted constant value file to a tran
