Multimodal downhole safety monitoring system

At present, the design of underground safety monitoring system is not perfect. A multi-modal underground safety monitoring system is proposed, which includes the multi-modal underground environment monitoring system and the multi-modal vital signs monitoring system of mine personnel. The safety monitoring system is built by combining the two aspects of underground environment and underground personnel. The multi-mode downhole environment monitoring system includes temperature sensor, humidity sensor, gas concentration sensor and alarm device. APP is built to connect with the system to realize real-time recording and display of environmental monitoring data. The multi-modal vital sign monitoring system of mine personnel starts from the acquisition, display and early warning of vital sign parameters of mine personnel, and monitors the physiological information of mine personnel in real time through communication module, data analysis module and data visualization module. The experiment proves that the system realizes real-time data transmission, recording and display, and the data transmission is stable and reliable, which can guarantee the life safety of underground personnel.
