When the holding furnace of the casting plant is heated for a long time, the bottom and side walls of the furnace are continuously eroded due to the flow of molten aluminum. When the insulation brick and castable are damaged to a certain extent, the molten aluminum contacts the bottom of the furnace or the side wall steel plate, and the temperature of the outer wall steel plate will rise, and the holding furnace has the risk of aluminum leakage. At present, the temperature measurement operation of the holding furnace is manually measured with an infrared thermometer. The environment in the workplace is complex, the space is narrow, and there is dust, high temperature, and waste slag falling, which causes very big obstacles to the manual inspection, and there is a greater safety risk in the operation process of the measurement personnel. Due to the low efficiency of manual measurement, long intervals, large deviation of temperature measurement position, different measurement habits, and other factors, there are errors in the measurement data.

The online temperature detection system developed by Jingwei Technology is a set of online temperature detection systems for holding furnaces, which adopts temperature sensor technology, low-power microprocessor technology, low-power anti-interference wireless communication technology, three-dimensional modeling technology, and computer software technology. The technology and equipment avoid the influence of human factors from the source; The real-time and accurate temperature monitoring and fault prediction in the running process of the mixing furnace are realized, so the above manual defects are technically solved.

The temperature of the holding furnace can be monitored 24 hours a day online in real time to ensure that the temperature abnormal points are monitored and warned in the first time. And the 3D three-dimensional model display is more real, vivid and accurate.

• High data security. It adopts LAN local service mode or 4G cloud mode for measurement data saving, viewing and related applications, and the data can be accessed within the using unit with high data security.
• Timely response to the temperature trend of the controlled point with a period of 10min/time to improve the monitoring efficiency.
• Voice intelligent alarm. Once the system detects the abnormal high temperature point, it will timely alarm through the voice broadcast, which is more intuitive and effective to remind the staff to carry out emergency treatment.
• The acquisition module has high flexibility and good mobility. It can be used simultaneously in the electrolytic cell of the whole plant.
• Mobile APP software can be used for remote monitoring, alarm, push, monitoring, and display content is rich and intuitive.
• The collection module is of rechargeable design, which can be recharged and used repeatedly, saving the environment.。
• The centralized display on the big screen can monitor the abnormal slots and anomalies on the site in real time to improve the refined management.
• Wireless communication network coverage is compatible with the access of various wireless communication devices in the later stage of the 5G smart factory.
