Description

Technical Field

[0001] The present invention relates to the field of management technology, and more specifically, to a management system and a weighing method for smart port weighing. Background Art

[0002] When traditional bulk cargoes such as grain are weighed at ports, it is usually necessary to ensure that the weighing device is in good working condition and to ensure its measurement accuracy by regularly calibrating the weighing device. However, when actually weighing at ports, it is easy to be disturbed by various factors, resulting in inaccurate measurements of the weighing equipment. In addition, vehicles need to pass through inclined surfaces when entering or leaving the weighing area. Cargo may fall or slip due to loose loading or improper handling, which may cause safety hazards or affect weighing accuracy. Falling cargo will also cause inaccurate weighing measurements of subsequent vehicles, thereby affecting the weighing accuracy of subsequent vehicles and causing inaccurate measurement results. The above problems exist in the prior art.

[0003] For example, a Chinese patent with application publication number CN220398700U discloses a vehicle weighing management system for ports, which belongs to the field of port technology and includes a platform, an upper gate and a lower gate. A weighing device is fixedly installed on the upper surface of the platform, and a connecting plate is fixedly installed on the left side of the upper gate and the left side of the lower gate. A connecting column is fixedly installed on the upper surface of each connecting plate, and a camera is fixedly installed on the upper surface of each connecting column. Each camera is electrically connected to the upper gate and the lower gate, and a ticket printing device is fixedly installed on the back of the platform, and the ticket printing device is electrically connected to the weighing device. The utility model, by providing an upper gate, a lower gate, a connecting plate, a connecting column and a camera, can collect vehicle information under the action of the camera, so that the vehicle can enter and exit the weighing area, thereby preventing queue jumping and jamming, thereby reducing road congestion near the scale and improving weighing efficiency.

When the hidden danger value exceeds the preset threshold, the system can immediately trigger an alarm, issue a timely warning, and prevent potential dangers. The third hidden danger alarm module monitors the abnormal value of vehicle weighing to ensure that when the abnormal value exceeds the preset range, the alarm is triggered in time to avoid affecting the stability and accuracy of subsequent vehicle weighing; by automatically extracting and comparing the hidden danger values ​​of the slope and the abnormal values ​​of vehicle weighing, the system can realize real-time monitoring and early warning, reducing the burden of manual monitoring and the probability of misjudgment, and improving the reliability of the system; timely hidden danger alarms allow staff to respond quickly, carry out necessary maintenance and adjustments, reduce the downtime of port equipment and operational interruptions, and improve the overall operational efficiency of the port.
