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.
