The invention discloses a data processing method, a data processing device, a data processing system and electronic equipment. The data processing method comprises the following steps of acquiring out-of-chain electric meter data, processing the out-of-chain electric meter data according to a preset error evaluation rule, then performing initial digital signature on the out-of-chain electric meter data, and broadcasting an initial signature result and the out-of-chain electric meter data to at least one other intelligent terminal in a terminal pool, verifying the authenticity of the out-of-chain electric meter data by adopting public key fragments and a preset signature verification algorithm to obtain a verification result, and performing digital signature on the out-of-chain electric meter data by adopting a complete private key, a system timestamp and a first preset signature algorithm to obtain a digital signature result, and uploading the initial signature result set, the out-of-chain electric meter data
