Intelligent judgment method and device for vehicle parking state in static rail weighbridge overbalance

Abstract

The invention discloses an intelligent judgment method and device for the vehicle parking state in static rail weighbridge overbalance, which can intelligently judge a parking position and give a prompt when the vehicle is loaded and unloaded to realize automatic acquisition of weight, vehicle number, position and vehicle type information by a double-carriage rail weighbridge, and the method and device are accurate in weighing and high in metering efficiency. The method comprises the steps of system construction, driving direction judgment, forward driving receiving axle number and vehicle position judgment and reverse driving receiving axle number and vehicle position judgment. The judgment device comprises a first small platform scale area, a first large platform scale area, a second large platform scale area, a second small platform scale area, a rail weighbridge, first to sixth wheel switch groups, and first to fourth vehicle number recognizers. Each wheel switch set is composed ofa first land wheel switch and a second land wheel switch which are symmetrically distributed along the central axis of the rail.

Description

technical field [0001] The invention belongs to the technical field of vehicle overweight, in particular to an intelligent judgment method and device for vehicle parking state during static rail scale overbalance. Background technique [0002] In the over-balancing of static track scales in ports, the traditional method is to judge whether the parking status of the train skin is correct with the naked eye, manually copy the train number, and then enter it into the system manually. These human factors will bring a lot of mistakes in the work. Inaccurate judgment of parking status will lead to inaccurate vehicle overweight weight, and errors in vehicle number entry will bring a lot of inconvenience to production. [0003] CN208902246U discloses a vehicle overbalance device, including an inductive proximity sensor, used to detect wheel position information of a vehicle to be overbalanced, and send the wheel position information to a controller; the controller is electrically co...

AI Technical Summary

Problems solved by technology

[0005] The problem that this device exists is as follows: 1, the first inductive type proximity sensor, the second inductive type proximity sensor, the 3rd inductive type proximity sensor and the 4th inductive type proximity sensor correspond to the four wheels at the front and rear ends of the short carriage of the train one by one, The first inductive proximity sensor, the second inductive proximity sensor, the fifth inductive proximity sensor and the sixth inductive proximity sensor are in one-to-one correspondence with the four wheels at the front and rear ends of the long train carriage. Judging and prompting the position, but not judging and prompting when the carriage has not reached the position of the weighing platform or the position of driving out of the weighing platform; 2. The specific use of two scales for over-balancing or using one scale for over-balancing is realized by manually switching the instrument , Once the judgment is wrong or the operation is wrong, it will bring a lot of mistakes to the work

3. One-time weighing can only be scaled for a single carriage, and the work efficiency is low; and it can only be scaled in one direction, and the unloading weight can be obtained by subtracting the vehicle tare weight obtained by the vehicle number identifier from the gross weight of the vehicle, but in the actual unloading process If the unloading is not complete, it will lead to inaccurate calculation results
