[0043] On the one hand, the present invention provides a CDQ furnace coke level monitoring system. Figure 1 As shown, it includes an image collector, an on-site processor, a remote controller and a coke loading device, wherein the image collector is arranged on the top of the dry quenching furnace 1 to be monitored, and the collecting end of the image collector is arranged in the dry quenching furnace 1 to be monitored, and is used to collect the coke image in the dry quenching furnace 1 to be monitored; the on-site processor is electrically connected to the image collector, and is used to obtain the coke image, and determine the real-time material level height of the coke based on the coke image, and compare the real-time material level height of the coke with the preset coke material level height to obtain a comparison result; the remote controller is electrically connected to the on-site processor, and the remote controller is also connected to the control of the coke loading device, and the remote controller is used to obtain the comparison result, and generate a control instruction based on the comparison result, and send the control instruction to the coke loading device to control the operation of the coke loading device.

[0044] The dry quenching furnace coke level monitoring system provided by the present invention acquires the coke image inside the dry quenching furnace in real time through the image collector, realizes the visual monitoring of the coke level, more accurately identifies and quantifies the accumulation state of the coke, thereby improving the accuracy of the level measurement, and also improving the intuitiveness and reliability of the level monitoring; the linkage between the on-site processor and the remote controller enables the system to accurately control the loading amount of coke according to the comparison result between the real-time level height and the preset value, quickly generate corresponding control instructions, and timely adjust the working state of the coke loading device, thereby ensuring the continuity and stability of the dry quenching furnace operation, thereby effectively improving the circulating cooling efficiency of the coke; the system automatically completes the whole process from image acquisition, processing and analysis to control instruction generation, reduces manual intervention, improves the automation level of operation, has a simple structure, and is flexible in operation; and the system can adapt to different dry quenching furnace environments, and can maintain normal operation even under harsh conditions such as high temperature and dust, thereby improving the scope of application and reliability of the system.

[0045] Specifically, in the above embodiment, if Figure 1 As shown, the system also includes an alarm device, which is electrically connected to the remote controller; when the comparison result indicates that the real-time coke material level height is lower than the preset coke material level height, the remote controller controls the coke loading device to load coke into the dry quenching furnace 1 to be monitored based on the control instruction, so that the coke height in the dry quenching furnace 1 to be monitored is equal to the preset coke material level height; when the comparison result indicates that the real-time coke material level height has reached the preset coke material level height, the remote controller controls the alarm device to alarm.

[0046] In this embodiment, the setting of the alarm device further enhances the safety and reliability of the system.

The coordinated connection between the camera 3 and the observation hole 2 ensures the stability of the installation of the camera 3 and reduces the risk of equipment displacement or damage caused by vibration or high temperature. The observation hole 2 is made of glass, has high transparency, and can maintain good optical properties and physical stability in a high temperature environment, thereby extending the service life.

[0049] Furthermore, the image collector also includes an image storage unit, which is electrically connected to the multiple cameras 3 and is used to store the coke image.

[0050] In this embodiment, the image storage unit can save coke image data, providing basic information for subsequent data analysis, troubleshooting and historical record query, ensuring the integrity and availability of the data; the stored images can be analyzed and processed when the system is offline, without taking up too many real-time processing resources, thereby improving system efficiency; and when an abnormality occurs in the system, the stored images can be traced back to help diagnose the problem, providing a basis for troubleshooting, and by analyzing the stored image data, deficiencies in the system operation can also be discovered, providing data support for system optimization and upgrading.

[0060] In this embodiment, in addition to using a remote processor to generate various control instructions, the present application also preserves the control method of operator intervention operation. Specifically, the comparison result is fed back to the operator, so that the operator can understand the current material level status in real time, enhance the transparency of the operation, and facilitate timely and correct judgment and decision-making; and the operator is allowed to input manual operation instructions according to the actual situation, which increases the flexibility of the system, so that manual intervention can be performed in special circumstances to deal with emergencies or special needs; the setting of the preset time can ensure that there is enough preparation time before the execution of the coking operation, avoids the safety hazards that may be caused by hasty operation, and improves the safety of operation; by combining manual instructions with system automatic control, the operation process is optimized, the accurate execution of the coking operation is ensured, and the impact caused by system misjudgment or delay is reduced; and the operator can respond to the system prompt more quickly and issue instructions in time to ensure that measures can be taken quickly when the material level is lower than the preset value, thereby improving the response efficiency; through clear operation instructions and preset time, the possibility of misoperation due to system or human factors is reduced, and the accuracy and reliability of the operation are improved.

[0061] Furthermore, after feeding back the comparison result to the operator, the method includes receiving an image storage instruction input by the operator, and storing the coke image based on the image storage instruction.
