Used to set a temperature threshold and compare the temperature monitored by the sensor; the integrated alarm circuit 33 is connected to the microprocessor control circuit 22 and is used to trigger visual and auditory alarms when the monitored temperature exceeds the set threshold. The photoelectric flame detection circuit 66 is used to detect whether the ignition source 55 has successfully ignited the thermal oil. The PLC44 is used to receive the signal from the photoelectric flame detection circuit 66 and control the start and stop of the ignition source 55. The system is started through the touch operation panel 11, and the target temperature is set as needed. The thermocouple 7 is installed at an appropriate position in the thermal oil temperature control kettle to monitor the temperature of the thermal oil in real time. The thermocouple 7 converts temperature changes into electrical signals. The microprocessor control circuit 22 compares the real-time temperature with the set temperature according to the preset temperature threshold and control algorithm. If the real-time temperature is lower than the set threshold, the microprocessor control circuit 22 sends an ignition signal to the ignition source 55. After receiving the ignition signal, the ignition source 55 starts the ignition process and ignites the thermal oil. The operation process of the entire system is automated. Through precise temperature control and flame monitoring, the system can adapt to different production needs while reducing operator risks and improving production efficiency.

[0020] To achieve accurate temperature measurement, refer to Figure 1As shown, the microprocessor control circuit 22 is an ARM-based microcontroller with data processing capabilities and user programmable interfaces. The integrated alarm circuit 33 includes an LED indicator and a buzzer. Based on signals from the microprocessor control circuit 22, the PLC 44 executes corresponding control logic, such as maintaining combustion, stopping ignition, or adjusting the fuel supply. The microprocessor control circuit 22 receives flame signals from the detector via a communication interface (such as RS422, HART, or Modbus protocols). The microprocessor control circuit (an ARM-based microcontroller) receives digital signals from the ADC. The microprocessor control circuit 22 compares the real-time temperature with the set temperature based on preset temperature thresholds and control algorithms. Users interact with the system through the touch panel 11 to perform operations such as temperature setting and ignition control. The photoelectric flame detection circuit 66 is an ultraviolet photoelectric flame detector that senses flame radiation and converts it into electrical signals for transmission to the PLC 44. The output signal line of the photoelectric flame detection circuit 66 is connected to the input port of the microprocessor control circuit 22. The installation position and angle of the photoelectric flame detection circuit 66 are adjusted according to the application environment to ensure optimal flame detection. The microprocessor control circuit 22 is connected to the thermocouple 7 via a dedicated thermocouple amplifier, performs analog-to-digital conversion via a built-in ADC, exchanges data with external sensors and amplifiers via a communication interface, and achieves precise temperature measurement and control through software programming. It also includes a touch operation panel 11, which integrates a display and a touch screen, providing an intuitive operating interface. It also includes an industrial Ethernet communication module for data exchange between the microprocessor control circuit 22 and the operator and control system. It also includes: a high-energy igniter for igniting the thermal oil; a fuel delivery module responsible for delivering fuel to the ignition source 55, including components such as a fuel pump, piping, and valves; a safety shut-off valve for cutting off the fuel supply when the emergency shutdown switch is activated; and an emergency power circuit breaker for cutting off power to the ignition system.

[0021] When in use, the system is started through the touch operation panel 11, and the target temperature is set as needed. The thermocouple 7 is installed at an appropriate position of the thermal oil temperature control kettle to monitor the temperature of the thermal oil in real time. The thermocouple 7 converts the temperature change into an electrical signal. The microprocessor control circuit 22 compares the real-time temperature with the set temperature according to the preset temperature threshold and control algorithm. If the real-time temperature is lower than the set threshold, the microprocessor control circuit 22 sends an ignition signal to the ignition source 55. After receiving the ignition signal, the ignition source 55 starts the ignition process and ignites the thermal oil.
