Description

Technical Field

[0001] The utility model relates to the technical field of workshop reconstruction, in particular to an automatic identification system for workstation transfer in a locomotive assembly test workshop. Background Art

[0002] Intelligence and informatization are important development directions for rail transit manufacturing companies. However, large manufacturing companies often use relatively basic monitoring equipment such as video surveillance, which can only provide post-event traceability. The manufacturing and assembly test workshops for large equipment such as locomotives usually have a large span, and each workstation is far apart. When the assembly tasks in the workshop are tight and the workstations are saturated, only a few responsible persons and workshop dispatchers in the complex assembly site know the current production and assembly status of each locomotive, and the on-site technical service personnel or supervisors cannot grasp the locomotive process status in real time and understand the locomotive position for the first time. Visitors from outside units will also cause a lot of trouble because they have no understanding of the workshop process layout. In this context, some companies will use electronic billboards, and dispatchers will be responsible for updating the status of the locomotive product workstations and processes every day, which invisibly increases the workload and also poses the risk of errors; some companies purchase workshop positioning equipment. Due to the large span of the locomotive manufacturing, assembly and test workshop, the test track can extend to dozens of kilometers. Equipment with low precision cannot accurately display the relative positions of each locomotive in the workshop. Purchasing equipment with higher positioning accuracy is expensive, and the positioning module that each locomotive must carry using this method also requires special management personnel.

[0003] In addition, the production tasks of locomotive assembly and test workshops are usually very saturated, and there is relatively strict time control for each workstation. The stay time at each workstation is not uniform due to different processes. The workshop dispatchers need to spend a lot of time to count the production progress of the workshop products and identify locomotive products that are delayed in production due to various reasons, resulting in a waste of manpower.

[0019] The example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present invention will be more comprehensive and complete, and the concept of the example embodiments will be fully conveyed to those skilled in the art.

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Some embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0022] In order to solve the technical problems existing in the prior art, this embodiment provides a locomotive assembly test workshop workstation transfer automatic identification system, including: an image acquisition module, an image recognition module and a display module;

[0023] The image acquisition module is connected to the image recognition module, and the image recognition module is connected to the display module;

[0024] Among them, the image acquisition module is used to obtain the image of the locomotive in the locomotive assembly test workshop, and transmit the image to the image recognition module; the image recognition module is used to identify the image to obtain the vehicle number of the locomotive, and transmit the vehicle number to the display module; the display module is used to display the vehicle number.

[0025] It can be understood that in the embodiment of the present utility model, since the locomotive assembly test workshop includes a plurality of workstations, each workstation is provided with at least one corresponding image acquisition module for acquiring the image of the locomotive in the workstation.

[0026] For example, see Figure 1 , showing a schematic layout of a locomotive assembly and test workshop.

[0027] like Figure 1 As shown, the workshop includes n workstations, each of which is provided with two cameras as image acquisition modules. The two cameras are respectively arranged at the two ends of the workstation to ensure that the image of the locomotive in each workstation can be fully acquired.

[0028] It should be noted that in the embodiment of the utility model, the recognition system is mainly used to identify the vehicle number of the locomotive, so the image acquisition module needs to ensure that the captured image includes the vehicle number information of the locomotive when performing image acquisition. In actual scenarios, the front and side of the locomotive will print the model and vehicle number before entering the workshop, so the image acquisition module can be set at the place where the front and side of the locomotive must pass to ensure that the vehicle number information of the locomotive can be collected.

[0029] It can be understood that in the embodiment of the utility model, the image recognition module can adopt an intelligent terminal installed with machine vision recognition software, such as a computer; the computer installed with machine vision recognition software can perform image recognition on the locomotive image captured by the image acquisition module, segment the background and the vehicle number in the image, and obtain the vehicle number information of the locomotive.

[0030] In this embodiment, the machine vision recognition software may be Halcon, VisionPro, LabView, EVision, HexSight or SherLock, etc.

[0031] It can be understood that in the embodiment of the utility model, the display module can adopt a display, which is mainly used to display the vehicle number information obtained after image recognition, and realize the positioning display of a locomotive product at a workstation in a locomotive assembly test workshop.

[0032] In some feasible embodiments, it further includes: a video recording module, which is connected to the image acquisition module.

[0033] It can be understood that the video recording module is used to record the locomotive image captured by the image acquisition module into a video. By way of example, in this embodiment, the video recording module can adopt a hard disk recorder, which is connected to the image acquisition module to obtain image information in real time and record it into a video, and the video can be stored in the recorder for later viewing.

[0034] It should be noted that a hard disk video recorder (DVR) is a digital video recorder. Compared with a traditional analog video recorder, it uses a hard disk to record videos, so it is often called a hard disk video recorder, also known as a DVR.

[0035] It is a computer system for image storage and processing, and has the functions of long-term video recording, recording, remote monitoring and control of images / voices. DVR uses digital recording technology, and is far superior to analog monitoring equipment in image processing, image storage, retrieval, backup, network transmission, remote control, etc. DVR represents the development direction of television monitoring systems and is the preferred product of television monitoring systems on the market. Due to its excellent monitoring performance, it is very suitable as a recording module in the embodiment of the utility model.

[0036] In some feasible embodiments, the system further comprises: a timing module, wherein the timing module records the time when the locomotive appears in the workstation based on the video.

[0037] In some feasible embodiments, it further includes: an alarm module, wherein the alarm module is connected to the timing module.

[0038] It is understandable that in an actual locomotive assembly workshop, each workstation has strict requirements for the processing time of the locomotive. If the locomotive is processed at a workstation for too long, it indicates that there is a fault in the current locomotive assembly test workshop. Therefore, in the embodiment of the utility model, a timing module and an alarm module are set accordingly. The timing module records the time when the locomotive appears in the workstation based on the video recorded by the video recording module. When the time exceeds the preset time, the timing module gives an alarm prompt to the alarm module, and the alarm module alarms.

[0039] For example, in the recorded video, timing is performed when the locomotive first appears at the workstation. If the locomotive does not move out of the current workstation within the set time, the timing module gives a prompt to the alarm module, and the alarm module sends a corresponding alarm message based on the prompt to prompt the staff.

[0040] It can be understood that in the embodiment of the present utility model, the timing module can be a timer, and the alarm module can be an alarm.

[0041] For example, see Figure 2 , showing a structural schematic diagram of an automatic identification system for locomotive assembly test workshop workstation transfer provided by an embodiment of the utility model.

[0042] like Figure 2 As shown, the system includes n cameras, switches, computers, video recorders and multiple displays.

[0043] First, these cameras are grouped according to the workstations to ensure that each workstation can capture the appearance of the locomotive. Then, each camera is connected to the video recorder and computer through a switch. The n cameras correspondingly obtain the image information of the locomotive in the n workstations, and then transmit the image information to the computer and video recorder through the switch.

[0044] The computer is installed with machine vision recognition software, which can recognize and process image information. The computer can separate the vehicle number from the background in the image information to obtain the vehicle number information of the locomotive. The obtained vehicle number information is finally transmitted to the monitor for display, and finally the recorded vehicle number information is marked on the corresponding workstation of the workshop electronic sand table.

[0045] The video recorder records the image information, and the recorded video is displayed on the monitor. The timer records the time when the locomotive appears in the workstation in the video. Since each workstation in the locomotive assembly and test workshop has relatively strict time control, if the locomotive appears in the current workstation for more than the preset time, the alarm will give an alarm prompt to remind the staff to make adjustments.

[0046] Those skilled in the art will readily come up with other embodiments of the present invention after considering the specification and practicing the embodiments disclosed herein. The present invention is intended to cover any variations, uses or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art that are not disclosed in the present invention. It should be understood that the present invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present invention is limited only by the appended claims.
