The method comprises the following steps: (1) all vehicle types and data parameters of trailer are memorized; (2) a mathematic model of 1 equal to A plus (P3 minus P'3) multiplied by ((C33 plus 1')/ Gcos Theta) plus delta of the center 1 of gravity of goods along the length direction of the container and a weight mathematic model of the front container and the rear container of G1 equal to G(3L' minus 2l)/2L' and G2 equal to G(2l-L')/ 2L' are established and written into recognition management software; wherein, A is a constant ranging from 400mm to 1000mm; Dheta is ranging from 0 DEG to 30 DEG; Delta is a correction coefficient; (3) data of the full vehicle weight W and weight of all axles under static heavy vehicle state are recorded, the total weight G of goods is equal to W minus T by calculation; (4) the center 1 of gravity of goods along the length direction of the container, the weight of the front container G1 and the weight of the rear container G2 are worked out. The weighing method can respectively measure weights of all axles, total weight and respective weight of two containers by one-step balancing.

Description

The branch mailbox meter weighing method of the two casees of container vehicle delivery

Technical field

The present invention relates to the branch mailbox meter weighing method of the two casees of a kind of container vehicle delivery, belong to the heavy field of meter of container carrier delivery container.

Background technology

Truck scale is as metering outfit mainly the weigh tare weight and the net weight of gross weight further to obtain carrying cargo of shipping goods vehicle, and the meter that has been widely used in the harbour goods is heavy.For the vehicle of delivery container, net weight is the container gross weight of having loaded goods, and promptly goods weight adds empty container weight.At present each big harbour mainly obtains the gross weight of container to weighing of container with truck scale, and along with the development of forwarding business, a container car loads the needs that a container can not satisfy logistics, and a car loads two containers sometimes.Therefore when container of container vehicle delivery, can claim to differentiate the weight of container by truck scale.But when two containers are housed on the container carrier simultaneously, can only be by special-purpose lifting scale, weighed to it in one of them container only back of slinging, or by suspender one of them container is placed on special-purpose weighing device it is weighed, not only cause weighting error bigger, but also influence shipment efficient.During therefore at present for two containers of container carrier delivery, truck scale is the weight that can't differentiate every container material object.

Summary of the invention

Goal of the invention of the present invention provides a kind of lorry that is loaded with two containers of working as and is parked on the truck scale, just can differentiate the branch mailbox meter weighing method of the two casees of container vehicle delivery of every Container Weight respectively.

The present invention is that the technical scheme that achieves the above object is: the branch mailbox meter weighing method of the two casees of a kind of container vehicle delivery is characterized in that:

(1), stores the wheelbase C of each vehicle trailer front axle and axis ₁₂, the wheelbase C between axis and the rear axle ₂₃, between trailer centrepin and the axis apart from l ", the heavy P of front axle axle under the curb weight T, complete vehicle curb condition ₁', the heavy P of axis axle ₂', the heavy P of rear axle axle ₃', the data parameters of the angle θ of Trailer type frame for use in vehicle and horizontal axis and container length L ';

(2), set up the mathematical model of container along the goods center of gravity l of its length direction $l=A+\frac{(P_3-P_3^{\′})\×(C_{23}+l^{\′\′})}{G\cos \mathrm{\θ}}+\mathrm{\δ},$ And the weight mathematical model of preceding container $G_{}$ ${}_1=\frac{G({3L}^{\′}-2l)}{{2L}^{\′}}$ Weight mathematical model with the back container $G_2=\frac{G(2l-L^{\′})}{{2L}^{\′}},$ And write in the identification management software, wherein: A is a constant value, and A is between 400mm～1000mm, and θ is between 0～30 °, and δ is a correction factor;

(3), the trailer that will be loaded with two in kind containers sails on the truck scale, and front axle, axis and the rear axle of trailer placed respectively on three separate unit scales of truck scale, writes down full car weight amount W and front axle axle weight P static loaded vehicle state under respectively ₁, the heavy P of axis axle ₂With the heavy P of rear axle axle ₃Data, calculate goods gross weight G=W-T;

(4), calculate container along the goods center of gravity l of its length direction, preceding Container Weight G ₁With back Container Weight G ₂, Container Weight G before the output ₁, back Container Weight G ₂, each heavily reaches the goods gross weight.

The present invention has set up container goods gravity balance equation along its length, when front axle, axis and the rear axle of heavy-duty vehicle is parked in three of truck scale respectively when independently weighing on the unit scale, can draw two Container Weights.The vehicle of loaded vehicle container of the present invention is as long as once static state is parked on the truck scale, just can measure respectively that each is heavy, the weight separately of gross weight and two containers, and operation is very easy, can not only guarantee the precision of weighing, nor can influence shipment efficient.Therefore the present invention can provide safeguard to the ship-loading and load-distribution management at harbour, the suspender safety when shipment lifts owing to can obtain the weight of two containers fast.

Description of drawings

Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.
