  • Patent number: 11445341
    Abstract: A dynamic weighing device has a plurality of weighing sensors that constitute a weighing sensor network via Ethernet. One of the weighing sensors is selected as a primary node, which performs time synchronization with the other nodes via a time synchronization protocol. Alternatively, the other nodes synchronize a time offset relative to the time of the primary node. Each weighing sensor continuously packetizes and sends a plurality of consecutive pieces of weighing information to a terminal apparatus. The terminal apparatus calculates a weighed weight result of the dynamic weighing device at the same moment, based on time information in the weighing information obtained through depacketization, In such a weighing sensor network, by means of the time synchronization, weighing data at each moment is accurate when the weighing data is processed on a terminal such as a meter, thereby improving the reliability of sampling.

  • Patent number: 11378441
    Abstract: 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.
