A method and apparatus for managing information about a measurement device, which is applied to a network system including a plurality of blockchains that includes a first blockchain and a second blockchain, data sender node devices and data manager node devices, the method can comprise receiving a cross-chain request from a data manager node device for device state information associated with a measurement device stored in the first blockchain, wherein the data manager node device is a node device for a second blockchain, verifying, in response to the cross-chain request, that a data manager associated with the data manager node is authorized to manage the device state information, obtaining a target depository transaction corresponding to the device state information, wherein the target depository transaction is stored on the first blockchain and was previously saved to the first blockchain by a data sender node device, wherein the data sender node device is a node device for the first blockchain, and performing management of the device state information based on the target depository transaction.

Method and apparatus for managing information about measurement device preliminary class

A method for operating a measurement device using a blockchain. A blockchain system comprises a lease platform node or lease platform node device, a lessor client, and a lessee client. Existing state information about the measurement device is stored in the blockchain. The method can include receiving a lease order for the measurement device that is sent by a lessee client, sending a lease notification based on the measurement device to the lessor client to notify the lessor to send the measurement device to the lessee, receiving, after the lessee receives the measurement device sent by the lessor, a device state detection request sent by the lessee client or the measurement device, wherein the device state detection request comprises first current state information about the measurement device, and detecting whether the first current state information matches the existing state information, and if yes, creating a lease contract for the measurement device.

Method and apparatus for managing measurement device based on blockchain

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.

A weighing system and a weighing method are disclosed having uninterrupted weighing functions. A plurality of load cells in the weighing system are arranged so that each load cell has a local small neighborhood, the local small neighborhood being defined by four neighboring points in front, back, left, and right of the load cell and four points on diagonal directions in a matrix. A weighing control module polls the load cells to determine whether there is failed load cell(s), and performs a calculation:(),where f is a non-linear mapping; andW. . . Wrepresents weighing outputs of load cells corresponding to the eight points in the local small neighborhood so as to calculate an estimated weighing output of the failed load cell.
