Infrasonic wave receiving alarm device and method

Abstract

The invention relates to an infrasonic wave receiving and warning device which comprises a receiving terminal, an earphone and a connecting wire, and the earphone is electrically connected with the receiving terminal through the connecting wire. The receiving terminal comprises a bearing shell, a connecting slide rail, a connecting buckle, a driving power supply, a wireless communication antenna, a capacitive infrasonic wave sensor, a control interface, a power supply wiring port, an earphone interface and a driving circuit. The using method comprises the three steps of equipment assembly, early warning operation and remote communication. On one hand, the system is simple in structure, flexible and convenient to carry and use, good in universality, high in integration degree and high in environment adaptability; on the other hand, the communication signal has the characteristics of low frequency, easy penetration, low attenuation and difficult absorption, so that the influence of a complex field environment on the communication signal is effectively overcome, potential safety hazards in a surrounding large-range environment are timely found in advance, and safety early warning is carried out on working personnel; therefore, the working construction safety and reliability are greatly improved.

Problems solved by technology

[0002] In actual production and life, especially in mines, tunnels and other load environments and environments with severe interference, the current communication devices based on electromagnetic waves are easily affected by terrain factors, propagation medium factors and complex magnetic field environment factors. The signal strength is severely attenuated, which seriously affects the reliability and stability of communication activities. This problem is especially prominent in mines and coal work sites;

[0003] In addition, in daily work, the monitoring of safety hazards is one of the important links in the current safety production. Currently, when monitoring safety hazards such as landslides, earthquakes, mudslides, and floods, it is often still carried out through traditional electromagnetic wave technology. Therefore, As a result, the monitoring accuracy and timeliness of the current safety hazard monitoring system are relatively poor. For example, the Chinese patent publication number is CN108573331A, a construction engineering hazard identification technology and method of use, including monitoring equipment, hazard identification server, storage and management client end, the monitoring device is connected to the hazard identification server, and the hazard server is connected to the management client and the storage

The hazard source data of the hazard source identification server is processed, so real-time hazard source identification technology is carried out, so the monitoring results are also easily affected by the quality of electromagnetic wave communication
