Strong earthquake record acquisition system based on wireless technology

Abstract

The invention discloses a strong earthquake record acquisition system based on the wireless technology. The system comprises acceleration sensors, analog signal processors, an analog-to-digital signalconverter, a master control CPU controller, a remote wireless 4G communication system, a GPS timing system, a power supply conversion module and a wind-solar complementary power supply system, threeacceleration sensors are separately connected with the analog-to-digital signal converter through respective analog signal processors, the analog-to-digital signal converter is connected with the master control CPU controller in a bidirectional manner, and the master control CPU controller is separately connected with the remote wireless 4G communication system and the GPS timing system in a bidirectional manner. According to the strong earthquake record acquisition system, data communication is performed by employing a mobile 4G communication technology adopted in a large area, large-range monitoring and laying of a monitoring network of a strong earthquake system can be realized, and the reliability of strong earthquake monitoring is guaranteed. The strong earthquake record acquisition system has characteristics of flat frequency characteristic response, linear phase change, good consistence of technical parameters, stable and reliable performance, low power consumption, and small size.

Description

technical field [0001] The invention relates to the field of strong motion monitoring, in particular to a strong motion recording acquisition system based on wireless technology. Background technique [0002] A strong motion recorder is an instrument that monitors the occurrence of earthquakes and records relevant parameters when earthquakes occur. The strong motion recorder is an automatic trigger seismograph that records strong earthquakes near the ground. It generally consists of five parts: a vibration pickup system, a recording system, a trigger-start system, a time stamping system, and a power supply system. With the development of the country's economy and society, the country has established a seismic network to monitor earthquakes and obtain seismic data. At the same time, it is stipulated that major engineering structures and special building structures must also be equipped with seismic monitoring devices. The occurrence of an earthquake itself is unpredictable, ...
