Description

  The present invention relates to a crushing plant monitoring system, and more particularly, to a crushing plant that crushes and processes waste materials discharged in various constructions to a reusable state and controls the processing steps while monitoring the processing steps.

  In recent years, waste materials such as concrete lumps discharged by building demolition and alfalt lumps discharged by road repair work are generally crushed to an appropriate size by a crushing device and reused as recycled aggregate It is the target. For example, in the crushing plant, when the waste material that has been carried is put into the receiving hopper, it is conveyed to the crushing device on the downstream side by a belt conveyor and crushed, and after removing the reinforcing bars etc. with a magnetic separator, it is aligned to a predetermined size. Delivered as recycled aggregate.

  In such a crushing plant, if too little waste material is transported by the belt conveyor, the waste material stays in the receiving hopper for a long time and tends to accumulate on the discharge side, causing hopper discharge troubles and being transported in the opposite direction. If there is too much waste material, the supply to the crushing device will be excessive, and crushing troubles will easily occur. Therefore, it is conceivable to appropriately arrange a person who monitors the status of waste material accumulation and crushing, but placing dedicated personnel at multiple locations in the process increases human costs and makes the person dangerous and harsh. Will be placed in a different environment.

  In response to such a problem, Japanese Patent Application Laid-Open No. 11-333318 discloses a method of remotely monitoring troubles such as clogging of waste materials in real time without allocating dedicated personnel by monitoring the state of crushing of waste materials during the process from the outside. A crushing control system has been proposed that can be easily detected. In addition, the present inventors / applicants previously disclosed in Japanese Patent Application Laid-Open No. 2003-76419 that the driver monitors the transport amount and the processing amount of the waste material with a monitor image of the work vehicle and controls the processing process from the work vehicle. We have proposed a monitoring system that can control the amount remotely, and these technologies can avoid the occurrence of trouble to some extent without causing an increase in management costs.

  However, even in the technology described above, the administrator cannot recognize the occurrence of a trouble or a sign of the trouble unless he / she actually looks at the monitor video of the relevant part in the processing process. As a result, there is a problem that the administrator's burden is likely to be excessive and the possibility of oversight cannot be fully denied. Further, it is not possible to grasp the overall situation in the processing process only by viewing individual monitor images.

  On the other hand, in JP 2000-89821 A, on the plant flow screen displaying the processing process of the plant, each of the equipment in the process is displayed as a symbol mark, and by selecting one of the symbol marks, A technique is described in which the detailed operating status of the equipment can be displayed on the screen. By monitoring using this plant flow screen, it is possible to grasp the overall situation while recognizing the state of each device in the processing process.

  However, with this technology, the administrator cannot directly control the equipment by operating on the screen, and the status of each equipment in the process can be instantly viewed only by looking at the entire plant flow screen. Since it is not possible to recognize, it is necessary to select the symbol mark of the place of interest each time and display the details, and it is difficult to say that this situation is sufficient for avoiding oversight.

In addition, as an arrangement | positioning location of a surveillance camera, it arrange | positions above the roll crusher 5 and confirms the biting condition of a waste material, arrange | positions above the belt conveyor of each crushing apparatus upstream, and confirms the flow of waste material. It is assumed that

  FIG. 7 shows a plant flow screen 110B by the crushing plant monitoring control system according to the second embodiment of the present invention. This screen is also when the equipment is partially in operation as in FIG. 3, and the symbol mark of the equipment that is operating in the same manner as described above has a different color scheme and the arrow line is also thick, Among the equipments that are operating, those that are accompanied by an operation are characterized by the fact that the symbol mark is also accompanied by the operation.

  In other words, the belt conveyor in operation is expressed in such a manner that the portion corresponding to the sprocket is seen to rotate, the roll crusher 5 is a mark 5h in which the roller appears to rotate, and the impact crusher 6 also has a rotating element rotating. It is expressed by a mark 6h in a form that can be seen. Further, the grizzly feeder 3 and the screen 8 that are vibrated during operation are represented by marks 3h and 8h that appear to vibrate.

  For this reason, each operating mark is easy to visually visualize the facility equipment that is actually operating, so the administrator can easily recognize the operation status of the facility equipment in each process of the plant at a glance. It has become. It should be noted that when the equipment is not actually moving but the power is turned on or has a workpiece, the color scheme changes, and when it actually starts moving, it may be added to the movement. This makes it easier to recognize the state of equipment in more detail.

  FIG. 8 shows a plant flow screen 110C as an application example of the plant flow screen 110B of FIG. On this screen, in addition to the movement of the symbol mark corresponding to the equipment that is operating along with the movement, the arrow line indicating the transport direction of the transported object has a dark color from the thin line when there is a transported object at that position. In addition to being changed to a thick line, the dot is characterized by being expressed as a mode in which dots constituting the broken line appear to move in the carrying direction while being indicated by a broken line instead of a solid line.

  For this reason, it is possible to immediately recognize the position where the workpiece is transported / moved by simply looking at the screen. Also, in the figure, the mark of the mountain at the position where iron scrap and recycled aggregate are piled up changes the color of the mark of the mountain in the situation where these are actually piled up. With respect to the marks 2i and 4i, the holding amount (bulk) at that time is expressed by a scale display by a horizontal line, so that it is easy to determine the amount and timing at which waste material or cutting material is introduced.

  Note that the plant flow screens 110A, 110B, and 110C described above are displayed on the displays of the display device 11a, the computer terminal 13, and the tablet terminals 14a and 14b, respectively, but the tablet terminals 14a and 14b having a relatively small screen size.
