This study designs a reliable and efficient spark detection technology and device by leveraging optoelectronic technology, which is integrated with automatic fire extinguishing systems and dust collector explosion prevention and suppression systems, aiming to realize the prevention, control and disaster mitigation of wood dust explosions in wood-based panel industrial production. This technology detects wood dust explosions by capturing the spectral characteristics of burning wood dust. The developed wood dust explosion detection device is split into two primary sections: hardware design and software design. In terms of hardware, the spark detection device is controlled by a DSPIC microcontroller, and comprises six main components: controller, amplifier circuit, photoelectric probe, upper computer, power supply module, and output module. It achieves rapid and accurate detection of wood dust combustion sparks via the acquisition, amplification and processing of spark signals. For the software section, the program consists of multiple modules including system initialization, parameter configuration, AD conversion, data processing, serial communication, and control signal output. Its basic functions primarily include rapid and accurate signal acquisition and processing, as well as stable data transmission and control through serial ports.
