The rising edge of one of the cigarette detection channels is used for identifying that the laser sensor module is close to the cigarette. The falling edge of one of the cigarette detection channels is used for identifying that the laser sensor module is far away from the cigarette. When one of the cigarette detection channels is detected to output a rising edge signal, judging whether each cigarette detection channel is in shortage or not. If the cigarette detection channel is in shortage, the number of times of the cigarette detection channel faults is increased by one. And when the number of faults reaches 5, judging that the cigarette detection channel has faults.
The fault detection statistical sign indicates that the laser sensor module is far away from the cigarettes, and the fault detection statistical sign is reset when each cigarette detection channel detects a falling edge. In contrast, if one of the cigarette detection channels detects a rising edge, the failure detection statistics flag is assigned to 1 to indicate that the laser sensor module is close to the cigarette. And if the laser sensor module is close to the cigarette, counting the failure times.
The WiFi data processing function is mainly responsible for receiving a request signal sent by the user terminal and returning a response signal. The request signal may include parameter setting and modification, status query and modification of on and off of the laser sensor, failure count query and clearing of the laser sensor, count query of cigarette detection, and sensitivity modification and query, etc.
