  • Patent number: 11967982
    Abstract: A method for real-time processing of a detection signal, wherein signal processing is respectively performed when a detection signal is converted from a high level to a low level or vice versa. A moment at which a level of the detection signal is converted is recorded as a start point. A status of the detection signal is then detected in real time at a current moment. A current time width is compared to a maximum interval width of pre-set interference signals, and signal levels are determined and recorded from the start point to the current moment. Using characteristics of different interference signals, anti-interference processing is performed by using a targeted edge positioning and width recognition method, so that the delay impact of filtering on signals is avoided, improving both the recognition precision of weighing data of a checkweigher and the overall performance of the checkweigher.

  • Patent number: 11669147
    Abstract: A method for dynamically managing power consumption, as well as a wake-up method, is disclosed for a wireless weighing platform. The method is initialized by setting both light and deep sleep period, entering a normal operating state, and starting light sleep timing. As long as no weighing operation is detected and the light sleep period has not expired, the method seeks to detect the weighing operation. If the light sleep period expires with no weighing operation, a light sleep state is entered, by turning off a communication function and starting timing for the deep sleep period. If no weighing is when the deep sleep period has expired, the wireless weighing platform enters a deep sleep state, by turning off power supply other than that for an acceleration sensor. If the acceleration sensor detects an effective vibration while in the deep sleep state, the normal operating state is restarted.

  • Patent number: 11573120
    Abstract: A method for adjusting parameters of a device with a weighing sensor collecting environmental parameter data of an environment where the device is currently located or environmental parameter data during execution of an application by the device. A zero compensation parameter is calculated and updated, based on the data collected. The method is applicable to a moisture analyzer and also to a vehicle scale. In the moisture analyzer, the method is triggered and executed in the analyzer, correcting the zero compensation data by using the environmental parameter data of an environment or environmental parameter data during execution of an application by the analyzer. Dynamic and real-time adjustment of a compensation parameter overcomes the problem that the scheme of pre-setting fixed parameters for zero compensation cannot deal with the complex zero drift encountered in actual environments.

  • 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.

  • Patent number: 11054299
    Abstract: A weighing device (1) has a load-bearing portion (10) that supports an object being weighed, a plurality of transition portions (20), and a separation portion (30). The transition portions are positioned on the separation portion, and the load-bearing portion is positioned on the transition portions, with the transition portions connected to the load-bearing portion and the separation portion. A plurality of weighing sensors (40) are provided at a bottom of the separation portion. A support portion (50) is below the weighing sensors to provide support therefor. The weighing device simplifies the loading condition of weighing sensors and isolates the horizontal mechanical deformation/distortion of the weighing load-bearing mechanism. It also reduces the influence of mechanical deformation/distortion, thereby improving the weighing performance and the effectiveness of the weighing device.

  • Patent number: 11029192
    Abstract: A high-capacity weighing module has a top plate weldment (10), a bottom plate weldment (30) and a pressure-bearing assembly (20) that is between the top and bottom plate weldments. Motion between the respective top and bottom plate weldments is restricted. This structure aids in easy installation and replacement of a sensor, and integrates the functions of anti-overturning and 360° inspection, and bottom stop. This makes the weighing module much more convenient to install than a conventional high-capacity module, and has a better safety function. The weighing module has advantage in terms of a simplified product structure, reduced cost of manufacture and maintenance, uncomplicated installation procedure, and higher safety and protection.

  • Patent number: 10782201
    Abstract: A platform scale uses a method of detecting a center-of-gravity (COG) offset. A weight value of a load on a weighing platform is calculated. The weighing platform is allowed to reach a steady state. When the weight value exceeds a COG offset threshold, then a position of a load COG is calculated using a load COG position algorithm. Whether the calculated position is in a valid region of the weighing platform is determined. The weight value is displayed if the position is within the valid region; otherwise, the position of the COG is displayed. A display apparatus of the scale displays the weight value or the position of COG of the load. The platform scale alerts a user about a possible invalid weighing event by displaying an image indicative of the COG offset condition, ensuring effective and precise weighing.
