Description

Method for controlling a image information of a computer numerical control apparatus

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of managing image information of a Computer Numerical Control apparatus (CNC), hereinafter, referred to as " CNC ". By implementing a process that can be carried out in a non-open CNC (CNC) environment, it stably eliminates the involvement of the operating system for the PC during the image display process, thereby "complicated operation of the system", "risk of information loss" Without, it relates to a CNC image information management method that can guide the normal image display procedure to proceed smoothly.

In general, CNC refers to a device that automatically controls the operation of a machine using numerical information consisting of codes and numbers. Recently, various CNCs have been widely applied to machines in various fields and contribute to the automation of production lines. .

See, for example, US Pat. No. 5604677, "Control of CNC machine tool," US Pat. No. 5727912, "Controller for CNC-operated machine tools." US Pat. No. 5,808,888. "Method and apparatus for programming a CNC machine", US Patent No. 6167325 "CNC data correction method", US Patent No. 6325697 "CNC machine tool ( CNC machine tools "and the like are disclosed in detail as an example of a CNC according to the prior art.

In general, such a conventional CNC displays various image information, for example, an alarm image, a maintenance image, a special situation operation instruction image, and the like on a display device, and confirms it to an operator, thereby making the overall machine operation process possible. I keep it normal.

In general, such image information is stored in a hard-disk of the PC block, and in this state, when a series of image information display processes are performed, the image information display tool installed in the CNC is stored in the PC block. The user can quickly search the existing image information, open the corresponding image information, and display the same on the display device.

However, under the above-described conventional CNC image information display system, as mentioned above, since the image information is stored and managed in the hard disk of the PC block, an operating system for the PC is indispensable to operate it normally. Thereby, the worker is forced to take the problem of the complexity of the whole system.

Moreover, when operating the CNC, the vibration of the mechanical block is inevitably transmitted to the PC block, in which case the hard-disk of the PC block is inevitably exposed to the vibration, and in this state, If no supplementary measures are taken, eventually, the hard-disk of the PC block will inevitably cause a problem of losing information stored therein, for example, image information.

Due to this problem, when the image information stored in the hard-disk is inevitably lost, even if a conventional CNC generates a series of image display request event, for example, alarm image, maintenance image, special situation operation It is impossible to flexibly display an image or the like on the display device, and as a result, the overall machine operation process cannot be maintained normally.

Accordingly, an object of the present invention is to implement a process that can proceed the overall image display process in a so-called non-open CNC (Non-open CNC) environment that does not have a PC block, through which the operating system for the PC in the image display procedure By stably eliminating the intervention of the user, it is to induce the normal image display procedure smoothly without the complicated operation of the system.

Another object of the present invention is to allow the entire image display process to be carried out independently in the CNC block itself without intervening the PC block, thereby preventing the inevitable loss of image information due to the vibration of the machine in advance. It is to prevent unnecessary problems in advance.

In order to achieve the above object, the present invention discloses an image information management method that is led by an image display management tool installed in a non-open CNC equipped with a CNC management module, a memory unit, and an input device / display device.

In this case, the image display management tool determines whether a series of image display request events have occurred from either the input device or the CNC management module, and when the image display request event occurs, through the CNC management module, After determining where the image is located in the memory unit, securing a series of temporary buffers in a part of the memory unit, opening a part of the memory unit in which the image is located, reading the image, and storing the read image in the temporary buffer. Determining whether the image stored in the temporary buffer has constructed and completed a series of valid images; and when the image stored in the temporary buffer has composed and completed a series of valid images, the image is transferred to the display device. A series of image information management processes consisting of a combination of output steps are performed.

Hereinafter, with reference to the accompanying drawings, it will be described in more detail the image information management method of the CNC according to the present invention.

First, as shown in Figure 1, the non-open type CNC system constituting the base environment of the present invention is largely a combination of the mechanical block 30 and the CNC block 10 that is powered by the power supply unit 90. Is done. Of course, under this non-open CNC system, the PC block is excluded from its installation.

At this time, as shown in the figure, the CNC block 10, the CNC management module 11, PMC management module 14, the memory unit 12, etc. are disposed, in this case, the CNC management module 11 The overall CNC operating process of the CNC block 10 plays a role in overall management, and the PMC management module 14 controls the signal relationship between the machine block 30 and the CNC block 10, the machine block 30 ) And the CNC block 10 to guide the smooth exchange of information between each other, the memory unit 12 is a series of signal connection relationship with the CNC management module 11 and PMC management module 14 In the state of forming a, it serves to store a variety of information necessary for the operation of the CNC management module 11 and PMC management module (14).

Here, in addition to the PMC management module 14 and the CNC management module 11 described above, the CNC block 10 is further provided with a display device management unit 16, an input device management unit 15, and the like. In this case, the display device management unit 16 forms a series of signal connection relationships with the image display management tool 100 unique to the present invention installed in the CNC management module 11, for example. It serves to transfer various image information transmitted from the display device 41. According to the interlocking action of the image display management tool 100 and the display device manager 16, various image information such as an alarm image, a maintenance image, a special situation operation instruction image, and the like may be stored in a predetermined region of the display device 41. It is displayed stably.

In addition, the input device management unit 15 serves to deliver various input information transmitted from the input device 42 to the CNC management module 11 while forming a series of signal connection relationships with the CNC management module 11. Perform. Based on the interlocking relationship between the CNC management module 11 and the input device management unit 15, the operator can transmit a series of information desired by the operator to the CNC management module 11 through the input device 15. have.

Under such a configuration, the PMC management module 14 is connected to the various output devices 32 arranged in the machine block 30 via the PMC input / output module 50, the relay unit 80, or the like, for example, a motor, hydraulic pressure. By transmitting the CNC information of the CNC management module 11 to a cylinder, a pneumatic cylinder, etc., the operation state of the corresponding output devices 32 is precisely and automatically controlled.

At this time, the sensor unit 31 disposed in the machine block 30 senses the operation state of each output device 32, and then relays the sensing result to the relay unit 80, the PMC input / output module 50, and the like. In this way, by transmitting to the PMC management module 14, it serves to guide the actual operating state of each output device 32 to be quickly delivered to the CNC management module (11).

In addition, the PMC management module 14 transfers CNC information of the CNC management module 11 to the main shaft motor 71, the angular shaft motor 72, and the like through the servo amplifier management module 60, thereby providing the corresponding motors. The operation state of (71, 72) is precisely and automatically controlled. In this case, the motors 71 and 72 feed back their operating states to the CNC management module 11 via the servo amplifier management module 60, thereby providing a CNC management module 11. They check their operation status from time to time.

In this case, as shown in FIG. 2, the image display management tool 100 unique to the present invention mentioned above includes an image display control unit 101, a CNC interface unit 104, a memory interface unit 105, and a display device interface unit. 103, the input device interface unit 106, and the like have a combined configuration.

Here, the CNC interface unit 104 is a medium between the above-mentioned CNC management module 11 and the image display control unit 101, the image display control unit 101 to display various information transmitted from the CNC management module 11 Or the various data transmitted from the image display control unit 101 to the CNC management module 11, and the memory interface unit 105 is provided between the memory unit 12 and the image display control unit 101. In the mediated state, the information stored in the memory unit 12 is transferred to the image display control unit 101, or the various data transferred from the image display control unit 101 is stably stored in the memory unit 12. do.

In addition, the display device interface unit 103 transfers various image information output from the image display control unit 101 to the display device management unit 16 in a state of intervening between the display device management unit 16 and the image display control unit 101. The input device interface unit 106 transmits a variety of input information output from the input device manager 15 while the input device manager 15 and the image display controller 101 are mediated. Serves to deliver to 101.

In this state, the image display control unit 101 receives the image display request information output from the CNC management module 14, the input device 42, etc. via the CNC interface 104 and the input device interface 106. If a series of image display request events occur, a specific image stored in the memory unit 12 is extracted through the memory interface unit 105, and the extracted image information is extracted. By transmitting to the display device interface 103, the image information can be promptly displayed on the display device 41.

Hereinafter, a method for managing image information unique to the present invention using the image display management tool 100 described above will be described in detail.

First, as shown in FIG. 3A, the image display control unit 101 continuously checks the CNC interface unit 104, the input device interface unit 106, and the like, thereby providing the CNC management module 11 and the input device 15. Then, it is determined whether or not a series of image display request events has occurred (step S1).

At this time, if it is determined that no separate image display request event has occurred from the CNC management module 11, the input device 15, or the like, the image display control unit 101 proceeds the flow to step S2 to perform a series of standby states. Keep it.

However, if it is determined that a series of image display request events have occurred from the CNC management module 11, the input device 15, or the like, the image display control unit 101 immediately controls the CNC via the CNC interface unit 104. A series of "image storage location information transfer request messages" is output to the management module 11 (step S3).

In this state, the image display control unit 101 continuously checks the CNC interface unit 104 to determine whether or not a series of image storage position information has been transmitted from the CNC management module 11 (step S4).

At this time, if it is determined from the CNC management module 11 that no separate image storage position information has yet been transmitted, the image display control unit 101 proceeds to the flow of step S5 to maintain a series of standby states.

However, if it is judged that a series of image storage position information has been transmitted from the CNC management module 11, the image display control unit 101 immediately displays the display device management unit 16 via the display device interface unit 103. It sends a series of video mode initialization request messages. In response to this message, the display device manager 16 quickly controls the display device 41, and as a result, the video mode of the display device 41 is initialized to, for example, "16 colors, 640x480".

Subsequently, the image display control unit 101 accesses the memory unit 12 via the memory interface unit 105, and then stores a temporary buffer for temporarily storing and storing image information in a part of the memory unit 12. "Is secured (step S7).

When the temporary buffer securing process is completed, the image display control unit 101 immediately opens a specific area of the memory unit 12 in which the display request image is located based on the previous image storage position information, and then displays the corresponding display. The request image is optionally read from the header and stored in the temporary buffer before (steps S8, S9, S10).

In this state, the image display control unit 101 determines whether or not the image stored in the temporary buffer has constructed and completed a series of valid images (step S11).

At this time, if it is determined that the image stored in the temporary buffer has not yet constituted a valid image of the completed form, the image display control unit 101 proceeds the flow to the previous step S10 to perform a series of image reading and storing processes. Repeat and proceed.

However, if it is determined that the image stored in the temporary buffer constitutes an effective image of the completed form, the image display control unit 101 immediately determines whether the image is an image requiring a series of flashing effects (step S12). ).

At this time, if the image is an image that requires a series of flashing effects, the image display control unit 101 immediately sets the flashing flag of the image to a value capable of blinking, and then sets the image to the display device interface unit. By passing through 103 to the display device manager 16, the image can be quickly posted to any one of the display windows 201,202,203,204 as shown in FIG. 4 (steps S13, S14). ). Here, in which display window the previous image will be posted "may vary depending on the situation.

Of course, in the previous step S12, when the image is an image that does not need a series of flashing effects, the image display control unit 101 transfers the image to the display device management unit 16 immediately after the step S13 is omitted. By doing so, the image can be quickly posted to any one of the display windows 201, 202, 203 and 204 (step S14).

As described above, in the case of the present invention, since the entire image display process is performed under a so-called non-open CNC environment without a PC block, the present invention stably excludes the intervention of the operating system for the PC during a series of image display procedures. In the end, when the present invention is implemented, the CNC is able to display the image normally, without complicated operation of the system, unlike the conventional art.

As such, when the entire image display process is independently performed in the CNC block itself without intervening the PC block, the inevitable loss of image information due to the vibration of the machine is prevented in advance, and as a result, the operator does not have an unnecessary problem in operating the machine. You can easily enjoy the effect blocked in advance.

Thereafter, the image display control unit 101 communicates with the memory unit 12 via the memory interface unit 105, closes the image storage area of the memory unit 12, and finishes the present invention first (step). S15).

On the other hand, through the above-described process, while the image information is posted on the display window of the display device 41, the image display control unit 101, as shown in Figure 3b, the input device interface unit 106 By continuously checking, it is determined whether or not a series of key input events has occurred (step S16).

At this time, when the operator selects the software keys 205, 206, and 207 through the key operation of the input device 42, and accordingly determines that a series of key input events have occurred from the input device manager 15, the image display control unit 101 ) Immediately judges again whether or not the corresponding key is a function-key in which "a series of functions are preset" (step S17).

Here, if it is determined that the key is not a function key, the image display control unit 101 proceeds to step S21 which describes the flow later.

However, if it is determined that the key is a function key, the image display control unit 101 immediately sends the display device manager 16, for example, the "current video mode release request message" via the display device interface 103. , "Previous Video Mode Return Request Message" and the like (steps S18, S19). In response to this message, the display management unit 16 quickly controls the display 41, so that the video mode of the display 41 is changed from the "image post type video mode" to the "image post situation". Video mode ".

Subsequently, the image display control unit 101 transmits, for example, the "function screen change request message" to the display device management unit 16 (step S20). In response to such a message, the display device manager 16 quickly controls the display device 41. As a result, a function screen corresponding to the function key is posted on the display window of the display device 41. The user can quickly see the desired function screen simultaneously with a series of function key operations.

On the other hand, in step S17 mentioned above, if it is determined that the key is not a function key, the image display control unit 101 requests a series of detailed image to view the "details of the image currently being posted in the display window" It is determined again whether or not the key is applied (step S21).

At this time, if it is determined that the key is not the detailed image request key, the image display control unit 101 ignores the current key input event and ends the flow, for example.

However, if it is determined that the key is a detailed image request key, the image display control unit 101 immediately repeats the above-described steps S3 to S14 to secure a series of detailed images, and then displays the corresponding detailed image on the display device. By transmitting to the management unit 16, a detailed image containing "details of the image currently being posted on the display window" can be quickly posted to any one of the display windows 201, 202, 203 and 204. Of course, in which display window this detailed image will be posted "may also vary depending on the situation.

On the other hand, if it is determined in the above-mentioned step S16 that a series of key input events have not occurred, the image display control unit 101 checks the CNC interface unit 104, whereby a series of CNC alarms from the CNC management module 11. It is judged whether or not this has occurred (step S22).

At this time, if it is determined that no separate CNC alarm has occurred from the CNC management module 11, the image display control unit 101 ends the flow, for example.

However, if it is determined that a series of CNC alarms has occurred from the CNC management module 11, the image display control unit 101 immediately attains the display device management unit 16, for example, via the display device interface unit 103. "Current video mode release request message", "previous video mode return request message", and the like are delivered (steps S23, S24). In response to this message, the display management unit 16 quickly controls the display 41, so that the video mode of the display 41 is changed from the "image post type video mode" to the "image post situation". Video mode ".

Then, the image display control unit 101 transmits, for example, a "CNC alarm screen switching request message" to the display device management unit 16 (step S25). In response to such a message, the display device manager 16 quickly controls the display device 41. As a result, an alarm screen corresponding to the corresponding alarm is posted on the display window of the display device 41. As soon as a series of alarms occur, the corresponding alarm screen can be viewed quickly.

As described in detail above, in the present invention, the entire image display process is performed under a so-called non-open CNC environment in which PC blocks are excluded.

As such, when the image display process is performed in a non-open CNC environment, the intervention of the operating system for the PC is stably excluded during the series of image display procedures. Consequently, when the present invention is implemented, the CNC is different from the conventional system. Without the complicated operation of the image, the image can be displayed normally.

As such, when the entire image display process is independently performed in the CNC block itself without intervening the PC block, the inevitable loss of image information due to the vibration of the machine is prevented in advance, and as a result, the operator does not have an unnecessary problem in operating the machine. You can easily enjoy the effect blocked in advance.

This invention can be variously modified depending on the situation.

For example, in the present invention, the temporary buffer module may be additionally disposed in a part of the image display management tool 100 without placing the temporary buffer above. Of course, even in this case, since the arrangement of the PC blocks is completely excluded, the aforementioned various effects are provided in the same way.

And, in the foregoing, specific embodiments of the present invention have been described and illustrated, but it is obvious that the present invention may be variously modified and implemented by those skilled in the art.

Such modified embodiments should not be understood individually from the technical spirit or point of view of the present invention and such modified embodiments should fall within the scope of the appended claims of the present invention.
