Problems solved by technology

At present, the ports have been using traditional methods to measure the weight of tandem container vehicles. One is to use special hoisting scales to weigh them in stages, which is costly and inefficient; Static weighing method, because the center of gravity is shifted due to uneven loading of the container, so not only the weight of a single box is inaccurate, but also cannot limit the weight of overweight boxes

Embodiment 1

[0028] (Embodiment 1 weighing system)

[0029] See figure 2 , the tandem container vehicle dynamic sub-box weighing system of the present embodiment includes a dynamic and dynamic shaft weighing platform 4, a dynamic scale detection instrument 5, a data acquisition device 6, a computer 7, a signal indicator light 9, a printer 10, and a static scale detection Meter 11 and static weighing platform 12. The static weighing platform 12 and the dynamic axis weighing platform 4 are connected in sequence according to the forward direction of the vehicle, and the two are equal in width and are on the same level above the ground; the dynamic weighing instrument 5 and the static weighing instrument 11 are respectively connected to the dynamic axis The weighing platform 4 and the static weighing platform 12 send the data to the data acquisition device 6; the data acquisition device 6 sends the aforementioned data to the computer 7 for analysis and calculation. The signal indicator ligh...

Embodiment 2

[0030] (embodiment 2 weighing method)

[0031] The weighing method of the present embodiment is carried out according to the following steps:

[0032] ① collect vehicle type data and container data, and store the data in computer 7; see figure 1 , the collected vehicle type data includes the distance m between tractor axles 1 , the distance between each axle of the trailer and the rear of the trailer d i , the distance between the center pin and the trailer rear l 3 , the weight of the unloaded tractor T 1 , Weight of unloaded trailer T 2 , Ground pressure F of the unloaded tractor 10 ; The collected container data includes the length L1 of the front container and the length L2 of the rear container.

[0033] ②Mathematical model L of the position of the center of gravity of the container along its length 1 ′, the weight mathematical model G1 of the front container 1, the weight mathematical model G2 of the rear container, and the optimal correction value K of each vehic...

Abstract

The invention discloses a weighing system and a weighing method for tandem double containers in a heavy vehicle state. The weighing system comprises a dynamic axis weighing table, a dynamic scale detection instrument, a data acquisition device, a computer, a static scale detection instrument and a static weighing table; the static weighing table and the dynamic axis weighing table are connected sequentially front and back according to the advancing direction of the vehicle, have equal width and are positioned on the same horizontal plane higher than the ground; the dynamic scale detection instrument and the static scale detection instrument are connected with the dynamic axis weighing table and the static weighing table respectively, and send data to the data acquisition device; and the data acquisition device sends the data to the computer for analysis and calculation. A primary function three-layer forward feedback neural network for dynamically calculating the weight of each container is established according to the data acquired when the vehicle passes through the dynamic and static combined weighing platforms, and a dynamic goods gravity center balance equation of the containers along the horizontal direction is establishes; and the calculation precision is high.

Description

technical field [0001] The invention relates to a tandem container vehicle dynamic case-dividing weighing system and a weighing method, which are mainly used in the field of container overload detection in ports and highway logistics industries. technical background [0002] With the rapid growth of our country's economy and the continuous increase of import and export trade, the use of containers to transport bulk goods is becoming more and more popular, and the issue of transportation safety has also been put on the agenda. In order to ensure the safety of transportation, it is required that the weight of the goods in each container shall not exceed the specified weight. In September 2008, the Ministry of Transport issued a document on the management of overweight domestic trade containers, requiring ports to strengthen the management of overweight containers and prevent overweight containers from entering the port. At present, the ports have been using traditional method...
