Abstract

The invention relates to a method and a warning system for unbalanced loading dynamic detection for a truck. The method comprises the following steps that: 1) the warning system for unbalanced loading dynamic detection for the truck is set, and the warning system comprises a signal sensing unit comprising a left acceleration sensor and a right acceleration sensor, an information acquisition control unit comprising a singlechip, and a warning prompt unit; the singlechip comprises two A / D conversion circuits and an unbalanced loading dynamic detection module; and an unbalanced loading warning threshold value and an unbalanced loading warning range are preset in the unbalanced loading dynamic detection module; 2) the left acceleration sensor and the right acceleration sensor acquire left and right acceleration signals of the truck; 3) the unbalanced loading dynamic detection module calculates the unbalanced loading coefficient of the truck; 4) the unbalanced loading dynamic detection module sends out corresponding warning signals to the warning prompt unit according to the calculated difference of the unbalanced loading coefficient of the truck and the preset unbalanced loading warning threshold value and by combining the preset unbalanced loading warning range; and 5) after the unbalanced loading dynamic detection module finishes unbalanced loading warning, the method returns to the step 2). The method and the warning system have high reliability and wide application, and can actively, accurately and timely provide unbalanced loading warning information of the truck during the transportation of the truck.

Description

technical field

[0001] The invention relates to a vehicle safety monitoring method and equipment, in particular to a dynamic detection method and an alarm system for unbalanced loading of a truck. Background technique

[0002] During the transportation of the car, due to the poor loading state of the goods, the unbalanced load occurs during the transportation process, and the drivers and passengers fail to detect it in time, thus inducing traffic accidents. The unbalanced loading of trucks is an important cause of traffic accidents at present. Therefore, controlling overloading and preventing unbalanced loading are important measures to prevent traffic accidents. The existing support technology mainly uses weighing instruments to measure the wheel weight to measure the load of the vehicle, which can also be used to understand the unbalanced load of the vehicle, but this technology is mostly used for railway vehicles. For example, the patent CN2443899Y "Dynamic Tester for Ov...

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Such as figure 1 As shown, the present invention includes a signal perception unit 1 , an information collection control unit 2 , and an alarm prompt unit 3 .

[0032] Such as figure 1 with figure 2As shown, the signal sensing unit 1 includes acceleration sensors 11 and 12 on the left and right sides of the truck, which are respectively fixed at the joints of the suspensions 5 on the left and right sides of the rear axle 4 of the truck and the connection between the suspension 5 and the cabin 6 for real-time perception of the left and right sides of the truck. The vertical acceleration signal is converted into a voltage signal and sent to the information collection control unit 2. Since the present invention mainly judges the unbalanced load situation of the truck according to the degree of difference in the vertical acceleration on both si...
