[0002] A car tipper is a large mechanical device used to tip and unload bulk materials from open railway cars. It is a loading and unloading machine that can flip or tilt rail cars to unload materials. It is suitable for ports with large transportation volumes and industrial sectors such as metallurgy, coal, and thermal power. Most mine cars in mines are unloaded using small car tippers. A car tipper can tip and unload 1 to 4 wagons at a time. Early equipment could only tip and unload 1 wagon, and the largest car tipper can tip and unload 4 wagons. Existing steel mills have multiple car tippers, with an average of about 1,500 vehicles tipped per day.

[0017] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings:

[0018] See Figure 1, is a schematic diagram of the structure of the utility model. The utility model is a vehicle state identification device for a dumper, comprising a vehicle number identification device, a weight sensor 3, a weight sensor control host 7, a vehicle number control host 2, a wireless transceiver 1, a vehicle number identification server 8, a weight identification server 9, a centralized control system server 10 and a centralized control terminal 11, wherein the vehicle number identification device is connected to the vehicle number control host 2, the vehicle number control host 2 is wirelessly connected to the vehicle number identification server via the wireless transceiver 1, the weight sensor 3 is connected to the weight sensor control host 7, the weight sensor control host 7 is wirelessly connected to the weight identification server 9 via the wireless transceiver 1, the vehicle number identification server 8 and the weight identification server 9 are connected to the centralized control system server 10, and the centralized control system server 10 is connected to the centralized control terminal 11;

[0019] The vehicle number recognition device includes a vehicle number magnetic strip, a microwave antenna 4, an operation box and a magnet 5. The operation box is arranged beside the track, and an operation button and an indicator light are arranged on the operation box. The vehicle number magnetic strip is arranged in the middle position of the bottom of the railway vehicle, and the microwave antenna 4 is arranged on the railway sleeper at the exit of the dumper. The height of the microwave antenna 4 is matched with the height of the vehicle number magnetic strip. The magnet 5 is a ship shape, and four magnets 5 are used. The magnets 5 are arranged on the rail bottom of the I-shaped groove of the rail 6 along the direction of the railway rail 6, and are symmetrically arranged on both sides of the microwave antenna 4. The two of the four magnets 5 close to the microwave antenna 4 are door opening magnets 5, and the two far from the microwave antenna 4 are machine starting magnets 5. The vertical distance between the magnet 5 and the antenna is 12 mm, the upper surface of the magnet 5 is 35 mm away from the rail head, the center distance between the door opening magnets 5 is 270 mm, and the inner wall of the magnet 5 is 1.5 mm away from the waist of the rail 6.

[0020] The measured weight of the weight sensor 3 is greater than or equal to 2.5t.

[0021] Working principle: A car number magnetic strip is installed in the middle of the bottom of the railway vehicle at the railway exit of the car tipping machine. The microwave antenna 4 emits microwaves to the car number magnetic strip. The car number magnetic strip reflects the magnetic strip data signal and returns to the car number control host 2 through the microwave antenna 4 to collect the railway vehicle number at the exit of the car tipping machine. The magnetic steel 5 collects the vehicle wheel signal. The distance between the starting magnetic steel 5 and the microwave antenna 4 can be adjusted according to the vehicle speed to determine whether the vehicle has passed. The magnetic steel is responsible for determining the direction of the vehicle and the vehicle axle counting and counting the number of vehicles. If the magnetic steel is damaged, the direction of the vehicle will be wrong and no space will be reserved for the unrecognized vehicle number. The centralized control system checks whether the collected data conforms to the working process of the car tipping machine, that is, when The license plate number of the vehicle sliding out of the tipping machine offline is consistent with the license plate number data of the vehicle sliding out of the tipping machine online in the centralized control system. The centralized control system determines that the vehicle license plate can be moved, and installs a weight sensor on the track at the exit of the tipping machine offline to collect the empty weight of the railway vehicle at the exit of the tipping machine offline. When the weight data is between 2.5 and 3.125t, the license plate is changed from a heavy vehicle to an empty vehicle. When the weight data is greater than 3.125t, the license plate will not be changed and manual intervention is required. The vehicle status change command is issued on the centralized control screen, and the heavy vehicle on the tipping machine automatically changes to an empty vehicle off the tipping machine, realizing automatic conversion of the vehicle status. The license plate recognition and weight sensing provide dual protection for the offline vehicles to ensure the accurate status of the vehicle.

[0022] The above embodiments are implemented based on the technical solution of the utility model, and detailed implementation methods and specific operation processes are given, but the protection scope of the utility model is not limited to the above embodiments. The methods used in the above embodiments are conventional methods unless otherwise specified.
