摘要： A method and apparatus are disclosed for managing a measurement device based on a blockchain, which is applied to node devices in a blockchain network. The method can include obtaining device state data of the measurement device at various stages in the life cycle of the measurement device; constructing a target transaction based on the obtained device state data, and then sending the target transaction to other node devices in the blockchain network to perform consensus processing on the target transaction; and storing, when a consensus of the target transaction is reached, the target transaction into a distributed ledger of the blockchain network, wherein the target transaction stored in the distributed ledger of the blockchain network is used for life cycle management of the measurement device.

摘要： An analog sensor with digital compensation function includes a deformation part generating a deformation relating to a pressure sensed by the analog sensor; a strain gauge connected to the deformation part and generating a change in resistance relating to the deformation; a strain gauge bridge connected to the strain gauge and transferring the change in the resistance of the at least one strain gauge to output a first analog signal; and an analog-to-digital conversion module converting the first analog signal to a first digital signal, representative of weight. A signal processing and output circuit compensates the first digital signal and converts it into a second analog signal.
