Safety helmet wearing detection circuit and safety helmet

The utility model discloses a safety helmet wearing detection circuit and a safety helmet, and the detection circuit comprises a pressure sensing module which is configured to sense a pressure value of a position where a safety helmet lining is attached to the head of a wearer, and output a voltage signal corresponding to the pressure value; the signal processing module is connected with the pressure sensing module, and is configured to perform sampling identification on the voltage signal, identify an actual voltage value, and generate an alarm driving signal if the actual voltage value is smaller than a preset threshold value within a preset duration; and the alarm module is connected with the signal processing module and is configured to give an alarm after receiving the alarm driving signal. The safety helmet wearing detection circuit is simple in structure, small in number of needed electronic components, low in cost and high in system stability. 本实用新型公开了一种安全帽佩戴检测电路及安全帽，检测电路包括：压力传感模块，被配置为感应安全帽内衬与佩戴人头顶贴合处
