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 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.

Method and apparatus for managing measurement device based on blockchain

The present invention discloses a weighing and measuring system, comprising a weighing sensor network constituted by networking a plurality of weighing sensors, wherein in the weighing sensor network, each of subtasks into which a weighing task is split is assigned to each of weighing sensors in the weighing sensor network; and each of the weighing sensors respectively and independently executes the assigned subtask and exchanges task data through the weighing sensor network. The weighing sensors collaboratively process a weighing task, which no longer depends on an instrument or a computer, thereby reducing the cost of the whole system, and improving the tolerance level to environment. The collaborative processing mode also avoids the bottleneck of data communication information summarization.

Collaborative weighing and measuring system and metering system

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.

Analog sensor with digital compensation function

A load cell wireless kit as disclosed can include a load cell and a kit component removably attached to an outside of the load cell. Exemplary embodiments are free of cables and a junction box, and can provide a great convenience for use and save power consumption, without affecting normal system functions.
