Description

Intelligent cutting data and welding data processing system

Technical Field

The invention relates to the technical field of steel processing, in particular to an intelligent cutting data and welding data processing system.

Background

At present, in the process of processing steel plates, the steel plates are cut, butted, welded and reshaped according to the shape requirements of products. And finally forming the product shape required by the user.

Generally, in the process of machining a steel plate or a steel material, cutting and welding are two indispensable processes. Generally, steel plates or steel materials are purchased from steel mills, cut according to the actual required size, and welded in groups. And some tubes need to be reeled and made into a cylinder body for subsequent application.

At present, manual processing is mostly adopted in the welding and cutting processes, because a welding machine or a cutting machine needs to be moved in the manual control process, if the cutting machine or the welding volume is large, great inconvenience is brought to the operation, and the welding machine or the cutting machine can only be dragged in an auxiliary mode by means of mechanical equipment. If the welding is carried out in the steel pipe, the welding machine cannot be dragged by the aid of mechanical equipment, and great inconvenience is brought to welding operation. And manual alignment easily causes errors to exceed the range and influences the product quality.

In the prior art, a common steel structure processing plant adopts a continuous production process, and products with the same specification are continuously produced, so that the production efficiency can be improved. Namely, a plurality of welding machines and cutting machines are adopted for processing and manufacturing. Generally, a welding and cutting operator is required to sequentially configure each welding machine and each cutting machine so as to simultaneously operate a plurality of welding machines and cutting machines when processing the same workpiece to be processed. Due to the configuration mode, a welding and cutting operator may repeatedly perform the same configuration on a plurality of welding machines and cutting machines, and the repeated configuration of the same operation process causes a complicated flow, and errors are easily generated to affect the processing quality. It also extends the length of time to perform the same operational configuration for multiple welders and cutters, reducing machining efficiency. Therefore, the welding and cutting operators sequentially perform the same operation on a plurality of welding machines and cutting machines, so that the processing efficiency is low, and errors are easy to occur when repeated configuration is performed, so that the processing quality is influenced.

Moreover, because a plurality of welding machines and cutting machines are involved in simultaneous operation, the monitoring of the manufacturing process data of each welding machine and each cutting machine is also crucial, unqualified problems can be found in time from the monitoring of the process data, or the operation or the processing procedure of the production process requirements cannot be met, but because a plurality of welding machines and cutting machines are involved in simultaneous operation, monitoring personnel cannot effectively and timely monitor each welding machine and each cutting machine, so that the monitoring is not in place easily, workpieces of the same type and the same size are produced, after the manufacturing is finished, the error is large, pairing is carried out in a subsequent process, or the installation cannot meet the use requirements, and further the whole manufacturing and installation period is delayed.

The welding and cutting device 2 may perform operations according to the received cutting process data or the number of welding processes. Therefore, the welding and cutting equipment 2 can process the workpiece to be processed under the control of the cutting and welding control terminal 1.

In the present invention, the welding and cutting device 2 performs a preset process operation in order to realize the same process operation to a plurality of welding and cutting devices 2. That is, when the same workpiece to be machined is machined, the plurality of welding and cutting devices 2 can be operated simultaneously, and here, the cutting and welding control terminal 1 controls the plurality of welding and cutting devices 2 to operate simultaneously, so that the mode of simultaneous and synchronous machining is met, and the machining efficiency is improved.

The Wireless internet Access technology may include Wireless Local Area network (Wi-Fi, WLAN), wireless broadband (Wibro), worldwide interoperability for microwave Access (Wimax), high Speed Downlink Packet Access (HSDPA), and so on.

In the embodiment provided by the invention, based on the repeated identical configuration of the welding and cutting operators mentioned in the prior art, the repeated identical configuration of the welding and cutting equipment 2 leads to a complicated flow, and errors are easy to occur, the processing quality is influenced, and the processing efficiency is reduced.

In the invention, the cutting and welding control terminal 1 can obtain the cutting process data or the welding process data preset by the welding and cutting operator. The cutting process data or the welding process data may be used to control a plurality of welding and cutting devices 2 to perform the above-mentioned predetermined operation process for machining a substitute workpiece. That is, the cutting and welding control terminal 1 may transmit the cutting process data or the welding process data to the welding and cutting device 2. The welding and cutting device 2 may perform the preset operation process based on the cutting process data or the welding process data.

Thus, the welding and cutting device 2 can perform a preset operation under the control of the cutting and welding control terminal 1. Here, the welding and cutting operator only needs to perform a preset operation on the welding and cutting control terminal 1, and does not need to perform a preset operation on the plurality of welding and cutting apparatuses 2 in sequence. Thereby, the execution of the preset operation process for the plurality of welding and cutting devices 2 can be simplified. Multiple presetting operations for a plurality of welding and cutting devices 2 are avoided. The efficiency of presetting the operation is carried out to a plurality of welding cutting equipment 2 to the promotion, has promoted machining efficiency, improves processingquality.

In the embodiment provided by the present invention, where a plurality of welding and cutting devices 2 are involved in the field, there may be some welding and cutting devices 2 involved in processing the pieces to be processed having the same processing technique.

In the invention, the cutting and welding control terminal 1 can send cutting process data or welding process data to the middle-end server. The middle-end server may forward the cutting process data or the welding process data to each welding and cutting device 2 in the welding and cutting processing group. Therefore, the cutting and welding control terminal 1 sends the cutting process data or the welding process data to the welding and cutting equipment 2 in a welding and cutting processing group mode.

In the present invention, the cutting and welding control terminal 1 may transmit the cutting process data or the welding process data to some welding and cutting devices 2 that do not need to receive the cutting process data or the welding process data during the process of transmitting the cutting process data or the welding process data to the welding and cutting devices 2. Therefore, the welding and cutting equipment 2 which does not need to participate in the processing performs the processing, or the welding and cutting equipment 2 which does not need to participate in the processing interferes, and the whole processing process is affected.

Here, the weld-cut processing group may be a set of devices. The cutting and welding control terminal 1 sends cutting process data or welding process data to the welding and cutting equipment 2 in the welding and cutting processing group of the equipment set, and it can be understood that the cutting and welding control terminal 1 sends cutting process data or welding process data to the welding and cutting equipment 2 in one divided equipment set. Therefore, the cutting and welding control terminal 1 can avoid sending the cutting process data or the welding process data to the welding and cutting equipment 2 which does not belong to the welding and cutting processing group in the process of sending the cutting process data or the welding process data to the welding and cutting equipment 2. Therefore, the accuracy of parameter configuration is improved, interference on the welding and cutting equipment 2 which does not need to participate in processing is avoided, and the whole processing process is also prevented from being influenced.

In the embodiment provided by the invention, the equipment address of the equipment set is configured to the cutting and welding local processing network. The cut-and-weld local area processing network may be a communication network pre-configured in the processing area. The welding and cutting device 2 and the cutting and welding control terminal machine 1 are added into a cutting and welding local processing network.

The middle-end server can be used as a server in a cutting and welding local processing network. And the middle-end server binds the addresses of the welding and cutting equipment 2 and the cutting and welding control terminal. Or based on the configuration of the user and the equipment address of the welding and cutting processing group, the welding and cutting equipment 2 corresponding to the equipment address is formed into the welding and cutting processing group.

In the embodiment provided by the invention, when the cutting process data or the welding process data are configured, the configuration can be performed based on the touch screen of the cutting and welding control terminal 1 or 3D software, and the processing coordinates are configured.

That is, the welding and cutting operator may configure the welding or cutting process of the machining operation on the machining coordinates, and may configure the corresponding welding position coordinates, or cutting position coordinates, based on the machining coordinates. The accuracy of the operation of the welding and cutting equipment 2 in the machining process under the control of the cutting and welding control terminal 1 can be improved.

In the process of controlling cutting or welding, the welding operator can perform touch operation on the cutting process data or the welding process data on the machining coordinates.

In the embodiment provided by the invention, the welding and cutting device 2 can execute the processing task based on the cutting or welding operation path formed by the processing coordinate configured by the cutting and welding control terminal 1.

The cutting or welding process video data captured by the image capture module may reflect cutting or welding process data of the welding and cutting device 2. The intercepted image may include one or more images. The appearance quality of the weld seam, or the appearance quality of the cut seam, etc. can be displayed in the image. And determining whether the preset operation process is met or not through the cutting or welding process video and the captured image.

As an embodiment of the present invention, the welding and cutting device 2 may send a cutting or welding process video to the middle-end server. The middle-end server may determine whether the current operation of the welding and cutting device 2 satisfies a preset operation process based on the cutting or welding process video transmitted by the welding and cutting device 2.

The middle-end server can store the process data of the cutting and welding control terminal 1, including the cutting or welding process video.

The welding and cutting operator intercepts a welding or cutting image from a video shot by the welding and cutting device 2, extracts a first welding or cutting feature for a welding or cutting pixel point contained in a welding or cutting image frame, and intercepts the welding or cutting image as a second welding or cutting feature based on the time sequence. And comparing the first welding or cutting characteristic with a preset image characteristic, and judging whether the operation process requirement is met. And comparing the second welding or cutting characteristic with a preset image characteristic, and judging whether the operation process requirement is met.

And comparing the similarity between the first welding or cutting characteristic and the second welding or cutting characteristic to judge whether the similarity is smaller than a preset welding or cutting characteristic threshold value or not, and further judging whether the operation process requirement is met or not. That is, the similarity deviation between the latter welding or cutting characteristic and the former welding or cutting characteristic is very large, which may be caused by unstable welding or cutting parameters, and the acquisition operation is improper, thereby affecting the welding or cutting quality.

Certainly, a third welding or cutting characteristic and the like can be obtained after the second welding or cutting characteristic is obtained, and comparison is performed based on the above manner, so that parameter state judgment of the welding and cutting process is realized, and the welding or cutting process meets the process requirements.

As an embodiment of the present invention, the welding and cutting device 2 performs a preset process operation in order to perform the same process operation on a plurality of welding and cutting devices 2. That is, when the same workpiece to be machined is machined, the plurality of welding and cutting devices 2 can be operated simultaneously, and here, the cutting and welding control terminal 1 controls the plurality of welding and cutting devices 2 to operate simultaneously, so that the mode of simultaneous and synchronous machining is met, and the machining efficiency is improved.

That is, before the workpieces to be processed having the same processing technology are processed, the device address input by the welding and cutting operator is acquired, and the welding and cutting device 2 corresponding to the selected device address is used as a welding and cutting processing group.

In order to ensure that each welding and cutting device 2 controls to synchronously execute welding or cutting operation, the cutting and welding control terminal 1 uniformly configures time information for each welding and cutting device 2 in a welding and cutting processing group. The time information of the cutting and welding control terminal 1 and each welding and cutting device 2 can also be configured uniformly based on the middle-end and middle-end server. And image acquisition of all the welding and cutting equipment 2 is realized, and data in the cutting or welding process are uniformly acquired and uniformly monitored and compared. And comparing the data with each other to obtain whether the current welding or cutting process data meets the preset process requirements.

The cutting and welding control terminal 1 acquires the welding or cutting video data of each welding and cutting device 2 and the corresponding welding or cutting time information.

In this embodiment, the middle-end server may also obtain the welding or cutting video data of each welding and cutting device 2 and the corresponding welding or cutting time information. The cutting and welding control terminal machine 1 extracts data required by a user from the middle-end server, processes and compares the data, and judges whether the current operation or the past operation process meets the process requirements.

The cutting and welding control terminal 1 extracts the image state of each frame in the video data according to the welding or cutting video data, and maps the image state to the welding or cutting state data of each pixel point.

That is, after the cutting control terminal 1 acquires the welding or cutting video data, it can correspond to each pixel point data of the preset image. The welding or cutting video data comprises a number of welding or cutting frames. For each welding or cutting frame, corresponding pixel data may be mapped. It can be understood that the extracted pixel points are obtained by thinning the weld joints or the cut joints.

And configuring welding or cutting frames based on the same time for each welding and cutting device 2 according to the synchronized system time, and storing the welding or cutting frames in a correlation mode. Meanwhile, based on the comparison of welding or cutting frames between the welding and cutting devices 2 in the welding and cutting processing group and the comparison of each pixel point data, whether a preset operation process is met or not is judged.

And based on the associated storage, the operator can conveniently inquire and compare the previous switching or welding data.

The time synchronization of the system to the individual welding and cutting devices 2 can be GPS synchronized time or time synchronized via a network.

The welding and cutting device 2 collects and transmits a welding or cutting frame in the cutting or welding process according to a preset collection time point and a preset transmission time point. Each welding or cutting frame acquisition and transmission is synchronized, but a preset time interval is configured from frame to frame.

That is, each welding or cutting frame is transmitted with a preset transmission interval so that the welding control terminal 1 can effectively distinguish each welding or cutting frame when receiving data.

In order to improve the communication efficiency of the cutting and welding process data, the welding and cutting device 2 may be configured with a cache to cache the cutting and welding process data and transmit the data based on a preset transmission time point. By caching the data of the cutting and welding processes, the time-consuming influence on the subsequent sending of the data of the cutting and welding processes can be reduced.

The cutting and welding control terminal 1 obtains the welding or cutting frame and the corresponding sending time, and judges whether the time is overtime.

And if the time is overtime, adjusting the preset sending interval or the sending time point of the welding and cutting equipment 2 according to the overtime duration.

When the judgment is overtime, the welding and cutting device 2 adjusts the preset transmission interval. Generally, the preset transmission interval is adjusted and decreased correspondingly according to the timeout time. And then, when the picture working data of the corresponding time frame of the next time is transmitted, the adjusted preset transmission interval is used.

By comparing and judging each welding or cutting frame, the synchronous operation, synchronous data acquisition and synchronous data transmission of the welding and cutting equipment 2 are ensured. If overtime happens, the next welding or cutting frame can be ensured to be timely sent and completed by adjusting the sending interval or the sending time point, so that the cutting and welding control terminal 1 is ensured to simultaneously control the plurality of welding and cutting devices 2 to operate simultaneously, the mode of simultaneous synchronous processing is met, and the processing efficiency is improved.
