[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The purpose is to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of this utility model, and to facilitate its implementation. It should be noted that the term "connection" in this application includes both electrical connections and conventional mechanical connections, and is not intended to limit this application. To make the technical solution of this utility model clearer, the present utility model will be explained and illustrated through the following embodiments.

[0018] This embodiment proposes a glass molten glass monitoring device for the overflow outlet of a glass furnace, such as... Figure 1 As shown, the device includes a camera, a sensor module, a servo motor, a control unit, an alarm device, and a display. The camera is connected to the control unit; the control unit is connected to the display, the sensor module, the servo motor, and the alarm device. The output shaft of the servo motor is connected to the camera, which is positioned above the overflow port. The servo motor is also connected to a bracket.

[0019] The camera is used to collect the picture of the glass liquid flowing out of the overflow port of the glass kiln in real time and transmit the picture to the control unit; the control unit processes the picture of the glass liquid and the data collected by the sensor module and transmits them to the display in real time to show them to the on-site staff, at the same time, the control unit also identifies whether the glass liquid has abnormal phenomena such as stones and abnormal temperature according to the picture of the glass liquid and the data collected by the sensor module, and sends a command to control the alarm device to alarm when an abnormality is found; further, the control unit can also send a command to the steering engine according to the data of the sensor module to automatically adjust the shooting angle of the camera, so that the camera can shoot a clearer picture of the glass liquid.

[0020] The steering engine is a position (angle) servo driver, which can drive the output shaft of the steering engine to rotate according to the control command of the control unit. In the embodiment, the camera is arranged on the output shaft of the steering engine, so that the steering engine can control the rotation of the camera to adjust the shooting angle. The steering engine control principle is simple, the structure is simple, and it is easy to install and implement.

[0021] Specifically, the control unit of the embodiment includes an IO controller and a processor, the processor is connected with the IO controller, and the IO controller is connected with the camera, the display, the sensor module, the steering engine and the alarm device respectively. The IO controller is the most basic control system for controlling the input and output of the processor, and is connected with various peripherals of the processor, on the one hand, the output data of the processor can be recognized by the peripherals, and on the other hand, the input of the peripherals can be recognized by the processor. The processor of the embodiment can adopt MCU (microcontroller unit), and other control chips can also be selected flexibly according to actual conditions during specific implementation. The MCU has the advantages of small size, high integration and strong data processing capability, and can meet the needs of reducing cost and improving monitoring accuracy of the device.

[0022] In the embodiment, the sensor module includes a camera angle sensor connected with the IO controller. Obviously, the camera angle sensor is arranged on the camera and used to collect the shooting angle of the camera in real time and transmit it to the control unit. The control unit can send a command to the steering engine according to the shooting angle of the camera and the real-time picture of the glass liquid, so as to rotate the camera through the steering engine, thereby adjusting the shooting angle of the camera to improve the clarity of the shooting picture and further improve the accuracy of monitoring by the control unit.

[0023] The sensor module of the embodiment also includes a temperature sensor arranged on the camera and connected with the IO controller. Temperature has a significant impact on the viscosity, uniformity and other key characteristics of the glass liquid. Temperature fluctuations can change the flow state of the glass liquid, causing uneven stress and stones in the glass, and other quality problems. Therefore, the embodiment is provided with a temperature sensor to collect the temperature of the overflow glass liquid in real time and send it to the control unit. When the control unit detects that the temperature is lower than the preset temperature threshold, it can also send a command to the alarm device to remind the staff.

[0024] In addition, the internal environment of the glass kiln is complex, and even with natural light, the light distribution at the overflow port may not be uniform, and there are shadow areas. In addition, the reflection and refraction characteristics of the glass liquid itself can make some areas dark. Therefore, the camera of the embodiment is also provided with a lighting lamp connected with the IO controller. The lighting lamp can provide uniform and stable light to ensure that the camera captures a clear image of the glass liquid flow, making it easier to accurately identify abnormal conditions such as stones. In specific implementation, when the control unit identifies that the camera-captured image is dark (for example, by comparing the real-time captured image brightness with a preset brightness threshold), it can automatically send a command to the lighting lamp to increase the brightness of the captured area, thereby improving the clarity of the captured image and improving the accuracy of the control unit monitoring.

[0025] In the embodiment, the alarm device includes a voice prompter connected with the IO controller. When the control unit identifies abnormal phenomena such as stones and temperature abnormalities, it will send a control command to the voice prompter, so that the voice prompter automatically broadcasts the overflow glass liquid, allowing on-site personnel to be alerted and address the problem in the first instance, improving work efficiency and avoiding equipment problems caused by stones and other issues.

[0026] In the embodiment, the display uses a human-computer interaction display screen. The human-computer interaction display screen not only provides real-time glass liquid state picture display for on-site personnel, but also retains the possibility of manual intervention. When the display screen cannot meet the personnel's needs, personnel can actively send a command to the control unit through the human-computer interaction display screen to further adjust the camera shooting angle and lighting lamp brightness.

[0027] In the embodiment, the support includes a support rod and a support column, one end of the support rod is connected with the steering engine, the other end is connected on the support column, and the support column is arranged on one side of the glass kiln. The support rod fixes the steering engine and the camera connected with the steering engine, so that the camera is fixed above the overflow port to shoot the glass liquid of the overflow port. In order to prevent the camera from shaking and causing unclear shooting picture, the support rod is not directly connected on the glass kiln, but connected on the support column arranged on one side of the glass kiln, so that the camera is prevented from shaking due to vibration of the glass kiln during work.

[0028] The application realizes automatic monitoring of the glass liquid of the overflow port of the glass kiln, can discover abnormality such as stone and too low temperature according to the picture transmitted by the camera and the temperature collected by the sensor, and timely alarms, can automatically adjust the angle and illumination of the camera according to the data collected by the sensor to improve the detection accuracy, and the like. In summary, the application can discover abnormality such as stone and temperature and timely alarms while improving the detection accuracy, so as to ensure the safety of the glass production line equipment.

[0029] The above is an exemplary description of the application with reference to the drawings. Obviously, the specific implementation of the application is not limited to the above method. As long as various non-essential improvements are made by using the method concept and technical solution of the application, or the above concept and technical solution of the application is directly applied to other occasions without improvement, they are all within the protection scope of the application.
