Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The intelligent kiln control system for the charcoal industry of the present invention comprises the following steps:

[0025] S1. Detection system: The intelligent kiln control system first requires an accurate detection system, which includes thermocouples for real-time monitoring of environmental parameters in the kiln. The thermocouple is the core component that can accurately reflect the temperature conditions in the kiln and provide data support for subsequent control.

[0026] S2. Control system: Based on the data from the detection system, the control system can automatically adjust various parameters in the kiln, such as the temperature controller, actuator valve and blower, to ensure the stability and efficiency of the charcoal production process.

[0028] S4. Remote operating system: The intelligent kiln control system is usually equipped with a remote operation interface, which allows operators to monitor and operate the kiln anytime and anywhere, which not only improves operational efficiency but also reduces labor costs.

[0029] In actual use, the thermocouple in the S1 detection system is installed in the carbonization kiln to monitor the temperature in the kiln in real time. The thermocouple, as a high-precision temperature sensor, is installed in a key position in the kiln, which can detect the temperature in the kiln in real time and accurately, and convert the temperature signal into an electrical signal and transmit it to the S2 control system. In the S2 control system, the temperature controller controls the opening of the actuator valve according to the preset step curve based on the temperature signal from the thermocouple, and then adjusts the oxygen blowing amount of the blower. All these data will be recorded in the S3 data processing and analysis system. In different carbonization stages, such as dehumidification period, cracking period and refining period, the data is analyzed and the optimal processing is made, and the oxygen intake is accurately controlled according to the temperature change to achieve the best carbonization effect. When the system encounters a problem that cannot be solved, such as when the temperature in the kiln exceeds the preset value, the indicator light comes on to remind the operator. At this time, the staff needs to manually control the kiln through the human-computer interaction interface to solve the problem. At the same time, the operation records at this time will be recorded and analyzed again through S3 and the data processing and analysis system to improve the system database. The entire system has both wired and wireless communication methods through the network information module. When performing manual control, it can be remotely controlled and can transmit the system's real-time data, alarm information and operation records to the remote monitoring center or mobile device. Through remote monitoring and data analysis, the operator can grasp the status of the kiln anytime and anywhere, respond to abnormal situations in a timely manner, and improve production efficiency and safety.
