This invention discloses a device for detecting the presence of coke in coke cans on a dry quenching coke transport vehicle, belonging to the field of coking technology. It includes a frame, a rotating turntable, and a support assembly. The support assembly consists of several sets of support seats and three sets of weighing platforms. The support seats and weighing platforms are evenly distributed in a ring on the upper surface of the frame, with the included angle between the three sets of weighing platforms being 120°. The rotating turntable is positioned above the support assembly and is guided by the support assembly to rotate. By placing the weighing platforms below the rotating turntable, the combined action of the support seats and weighing platforms achieves both support and guidance for the rotating turntable, without affecting its rotational function. This also enables real-time detection of the actual weight of the coke cans, revealing the current coke storage status within the cans. The use of three sets of weighing platforms at a 120° angle ensures the accuracy and stability of the weight acquisition signal. Furthermore, the cross-verification of the detection data from the three sets of weighing platforms ensures the accuracy of the detection results.

This invention relates to the field of new energy vehicle control, specifically to a method for estimating the overall vehicle weight of a range-extended electric commercial vehicle. The method involves collecting raw signals from the vehicle's CAN bus or sensors, filtering these raw signals to obtain a preprocessed signal, and determining whether the KF enable condition is met based on the preprocessed signal. If met, the weight and gradient estimation are enabled; otherwise, the estimation is paused and the current estimated value is frozen. A regression coordinator is used to determine the enable period, and a serial extended Kalman filter architecture is employed to estimate the road gradient and overall vehicle weight. A convergence checker determines whether the estimated value meets the convergence criterion. This method solves the problems of poor accuracy in current vehicle weight estimation and the significant impact of large weight variations on some vehicle functions, making it difficult to accurately identify the actual vehicle weight.
