[0098] Example

[0099] The wheel manufacturing identification image acquisition device of this embodiment can realize automatic recognition of basic marks and wheel diameter parameters of rolled steel and cast steel wheels, complete automatic recognition of wheel quantity statistics, and complete external data output of recognized wheel data.

[0100] Wheels are divided into cast steel wheels and rolled steel wheels. Due to the difference in processing technology, the surface of rolled steel wheels is more prone to rust than cast steel wheels. The logo on the wheel is usually located in Figure 3 The inner ring of the wheel is shown, so if it is a rolled steel wheel, it may be necessary to remove rust from this position through the rust removal unit to clearly display the wheel logo. The rust removal unit can complete the rust removal of the basic mark of the rolled steel wheel and improve the recognition rate of the basic mark. It is located directly above the assembly line 1 and contacts the upper side of the wheel for rust removal.

[0101] When the wheel is a rolled steel wheel, the control unit 5 can generate a roller start / stop control signal and input it into the roller power device through triggering by an operator or automatic identification, so as to control the roller power device to start, thereby driving the rust removal roller 3-2 to rotate. The surface of the rust removal roller 3-2 is covered with steel sand or steel wire, and can grind the inner ring side of the rolled steel wheel through rapid rotation, thereby revealing the wheel mark.

[0102] The image acquisition unit 4 is located in front of the rust removal unit along the moving direction of the assembly line. The image acquisition unit 4 uses an area array camera to take pictures and collects the upper surface image information of the rolled steel wheel and the cast steel wheel. If the wheel needs to be rusted, it can be moved to the bottom of the image acquisition processing unit 4 for image acquisition after passing through the rust removal unit. The wheel image with the wheel logo is collected and then sent to the database of the host computer for comparison to determine whether the wheel logo meets the field attributes pre-stored in the library.

[0103] If the wheel is a cast steel wheel, it is usually not necessary to grind the cast steel wheel, so the rust removal unit does not need to work. The control unit 5 can generate a roller start / stop control signal and input it into the roller power device through operator triggering or automatic recognition, so as to control the roller power device to stop, thereby driving the rust removal roller 3-2 to stop rotating. The steel wheel can directly pass through the rust removal unit and then move to the bottom of the image acquisition processing unit 4 for image acquisition. The wheel image with the wheel logo is collected and then sent to the database of the host computer for image recognition and field comparison to determine whether the wheel logo meets the field attributes pre-stored in the library.

[0104] For example: Wheel manufacturing year: 24, manufacturing month: 05, manufacturing unit code: TZ, steel grade code: Ⅲ, wheel model: rolled steel HESA, production furnace number: D1241343, wheel serial number: 164382, wheel diameter: 845.1.

[0105] If the image recognition is wrong, the host computer will find the error after comparison and can perform subsequent reminder operations.

[0106] The control unit 5 may have the functions of the host computer. The image recognition algorithms used by the control unit 5 are existing algorithms, and the generation of various signals is based on existing control programs, which can be obtained by referring to the user manuals and public information of related hardware.

[0107] The control unit 5 generates a roller start / stop control signal which is input to the switch signal input terminal of the frequency converter 3-3 to control the frequency converter 3-3 to be turned on or off. When the frequency converter 3-3 is turned on, the roller motor 3-4 can be controlled to rotate at a preset frequency.

[0108] The rust removal switch 6 may have three gear positions, wherein one gear position indicates the working state of the rolled steel wheel, one gear position indicates the working state of the cast steel wheel, and one gear position indicates the standby state.

[0109] When the rust removal switch 6 is turned to the steel rolling wheel working state, a switch signal of the rust removal switch 6 is input to the control unit 5 as the roller start instruction of the control unit 5. After receiving the roller start instruction, the control unit 5 generates a roller start / stop control signal and inputs it to the switch signal input terminal of the frequency converter 3-3 to control the start of the frequency converter 3-3.

[0110] When the rust removal switch 6 is turned to the cast steel wheel working state, a switch signal of the rust removal switch 6 is input to the control unit 5 as a roller stop command of the control unit 5. After receiving the roller stop command, the control unit 5 generates a roller start / stop control signal and inputs it to the switch signal input terminal of the inverter 3-3 to control the shutdown of the inverter 3-3.

[0111] When the rust removal switch 6 is turned to the standby state, a switch signal is input to the control unit 5 as a collection trigger stop instruction of the control unit 5. The control unit 5 does not perform subsequent work after collecting any trigger signal of the triggering sensor 7.

[0112] The acquisition triggering through-beam sensors 7 all adopt through-beam photoelectric sensors to provide trigger signals for the image acquisition unit 4 so that the image acquisition unit 4 acquires wheel images that meet the requirements. There are two pairs of them distributed on both sides of the assembly line 1, one pair is located at the front end of the horizontal position of the image acquisition unit 4, and the other pair is located directly below the image acquisition unit 4.

[0113] The wheel moves on the assembly line 1, first passing through a pair of acquisition triggering opposing beam sensors 7, the wheel blocks a pair of acquisition triggering opposing beam sensors 7, the signal changes from high to low to form a first switch signal as the first image acquisition trigger signal of the control unit 5, which is input to the control unit 5. The wheel continues to move on the assembly line 1, the wheel blocks another pair of acquisition triggering opposing beam sensors 7, the signal changes from high to low to form a second switch signal as the second image acquisition trigger signal of the control unit 5, which is input to the control unit 5. Since the connection line of a pair of acquisition triggering opposing beam sensors 7 is parallel to the connection line of another pair of image sensors and the straight-line distance between the two (hereinafter referred to as the distance between the two pairs of acquisition triggering opposing beam sensors 7) is less than the diameter of the wheel, the wheel has a state of blocking the two pairs of acquisition triggering opposing beam sensors 7 when in use, at which time the control unit 5 detects the existence of the first image acquisition trigger signal and the second image acquisition trigger signal when in use, and generates an image acquisition instruction to input to the image acquisition unit 4, and the image acquisition unit 4 performs wheel image acquisition after receiving the image acquisition instruction.

[0114] Due to the different angles of the wheels, the wheel marks may be located at different positions in the image acquisition area. In order to ensure that the image acquisition unit 4 can obtain the image with the wheel mark at one time, the image acquisition unit 4 should capture the complete wheel image as much as possible. Therefore, the distance between the two pairs of acquisition triggering and shooting sensors 7 can be set to be slightly smaller than the wheel diameter. For example, if the diameter of the wheel is 845.1 mm, the distance between the two pairs of acquisition triggering and shooting sensors 7 can be set to 840 mm.

[0115] The acquisition triggering and shooting sensor 7 can also be used as a counter. When the wheel passes a pair of acquisition triggering and shooting sensors 7 on the assembly line 1, the switching signal formed by the signal changing from high to low is also input to the control unit 5 as the wheel counting signal of the control unit 5, and the control unit adds 1 to the initial total number of wheels.

[0116] The wheel image with the wheel identification is collected and then sent to the database of the host computer for image recognition and field comparison to determine whether the wheel identification conforms to the field attributes pre-stored in the database.

[0117] If the image recognition is wrong, the host computer will find the error after comparison, and then generate image recognition error information (which can be text information) and send it to the control unit 5. The control unit 5 generates an image recognition error sound signal (converting text to sound in a specific format) based on the image recognition error information to remind the operator.

[0118] The control terminal 9 is located beside the on-site assembly line 1, and the operator operates and observes the device through the control terminal 9.

[0119] The control unit 5 generates a wheel count display signal based on the wheel count signal, generates an image recognition result display signal based on the image recognition result (wheel identification) sent back by the host computer, and generates an image recognition error display signal based on the image recognition error information sent back by the host computer. All of these are input into the display drive unit of the control end 9 and displayed through the display component of the control end 9.

[0120] At the same time, in order to further improve the functions of the control terminal 9, the control terminal 9 can also display the number of wheels passing through the wheel mark identification platform on the day, this week, and this month based on the existing production software, read, review current and historical alarm records, and manually correct identification information errors.

[0121] The control terminal 9 can also use existing production software to manage the device, display the working status of the device, and set the working parameters of the device.

[0122] The emergency stop switch 10 is used to perform an emergency stop on the roller motor 3-4. The motor control signal between the frequency converter 3-3 and the roller motor 3-4 is first disconnected in series. Then, the switch signal generated when the emergency stop switch 10 is in the disconnected state is input to the control unit 5 as a roller shutdown instruction, thereby controlling the frequency converter 3-3 to stop running.

[0123] The emergency stop switch 10 can be arranged beside the control terminal 9 so that the operator can operate it in time when the control terminal 9 is working.

[0124] A plurality of emergency stop switches 10 can be provided, connected in series, and when one of them is disconnected, the roller motor 3-4 can be emergency stopped. A plurality of emergency stop switches 10 can be provided near the control terminal 9, so that the operator can operate them in time when the control terminal 9 is working. They can also be provided near the rust removal unit, so that the operator can operate them in time when observing the rust removal unit and finding that the roller motor 3-4 needs to be emergency stopped.

[0125] The lighting unit 11 is a strobe light, which is used to supplement the image acquisition unit 4. The image acquisition unit and the lighting unit 11 are integrated in the camera box. The image quality is not affected by the ambient light.

[0126] The control unit and the sound prompt unit 8 are both placed in the cabinet.

[0127] This device can replace manual work, automatically identify the factory identification of the wheel and automatically connect with the HMIS device to enter the identification information in the HMIS device:

[0128] The specific working process is that when the rolled steel wheel is in operation, the device is initialized, the rust removal switch 6 (knob switch) is turned to the rolled steel wheel working state, the rust cleaning module enters the working state, the rust on the basic mark of the rolled steel wheel is cleaned, the assembly line 1 of the railway truck wheel factory operates normally, the wheel blocks the shooting switch, the signal changes from high to low, and the switch signal is converted into a digital signal through the I / O module and transmitted to the control unit 5 through TCP; the control unit 5 sends a trigger signal to the image acquisition unit 4, and the camera in the image acquisition unit 4 synchronously triggers the LED lighting unit 11 to fill light. The image acquisition unit 4 collects the image information on the upper surface of the wheel, uploads it to the control unit 5, and completes the intelligent recognition of the basic mark of the rolled steel wheel and the intelligent recognition of the wheel diameter parameter. When the wheel mark recognition error occurs, the sound prompt unit 8 plays a sound prompt. The assembly line 1 operates in sequence to complete the automatic recognition of the wheel manufacturing mark and the number of wheels.

[0129] Cast steel wheel operation:

[0130] The rust removal switch 6 (knob switch) is turned to the working state of the cast steel wheel, and the rust cleaning module does not work. The other operations are the same as the above.

[0131] In this device, image acquisition and positioning are combined, and the wheel mark data is recognized by image;

[0132] Improve work efficiency. It is estimated that the use of this device can reduce the workload of each wheel by 20%, and at least improve the efficiency of the assembly line 1 by 20%.

[0133] Improve accuracy. The target recognition accuracy of this device is over 99.8%, and it can achieve an average of 1 error in 480 wheels in 4 days, which is twice the accuracy of manual detection.

[0134] The digital vehicle depot and device application can realize digital management of the daily and monthly workload of the wheel workshop, from wheel data collection, analysis and entry of factory identification to information statistics to realize automated management, which will help the vehicle depot to transform and upgrade digitally, improve the vehicle depot's operating efficiency and service quality, and enhance safety.
