Problems solved by technology

[0003] At present, there is no relatively complete data acquisition device for exploration geophysics teaching experiments at home and abroad. When it comes to exploration geophysics data acquisition and other experimental courses, colleges and universities in my country do not have corresponding exclusive teaching instruments, and often use exploration geophysics engineering instruments to carry out teaching, making The teaching effect and experimental operation are difficult to meet expectations. Therefore, the development of a wireless network-based exploration geophysics teaching experiment data acquisition device is of great significance to the current talent training in the field of electrical prospecting.

Embodiment 1

[0015] A wireless network-based data acquisition device for exploration geophysics teaching experiments, consisting of a constant current source U1, an analog switch U2, a front-end amplifier circuit U3, an active filter circuit U4, a front-end amplifier circuit U5, a band-pass filter circuit U6, and a follower circuit It is composed of U7, analog switch U8, program-controlled amplifier circuit U9, differential amplifier circuit U10, and AD conversion circuit U11.

[0016] One signal of the input signal enters the analog switch from the No. 8 pin of the electrode, overvoltage protection and constant current source U1, passes through the front-end amplifier circuit U3, and is filtered and shaped by the active filter circuit U4, and is output from the No. 24 pin.

[0017] The other vibration signal is protected by the wave detector and input to the No. 3 pin of the front-end amplifier circuit U5. After processing, it is output from the No. 1 pin and enters the No. pin out.

Abstract

The invention discloses an exploration geophysics teaching experimental data collection device based on a wireless network. A 24-bit ADS127L01AD conversion circuit with the collection rate of 512kSPS is used as the core of an analog circuit part for data collection. The analog part further comprises a front end amplifier circuit, a linear amplifier circuit, a filter forming circuit and a differential input circuit. According to the invention, the operation function of exploration geophysics experiment is realized through the wireless network; and geophysics experimental data collection and experimental teaching are well combined, which is convenient for students to understand and convenient for teachers to carry out experimental teaching.

Description

technical field [0001] The invention belongs to engineering geophysics exploration technology, in particular to a wireless network-based exploration geophysics teaching experiment data acquisition device. Background technique [0002] Geophysical prospecting can help humans grasp the distribution of underground mineral resources, and on the other hand, it can effectively warn various geological disasters. Geophysical exploration instruments have a wide range of exploration and are widely used. With the rapid development of geophysical exploration, through continuous improvement and perfection, exploration geophysical acquisition devices have been widely used in various fields. Obvious geological effects and significant social and economic benefits have been achieved in hydrological, engineering and environmental geological surveys. [0003] At present, there is no relatively complete data acquisition device for exploration geophysics teaching experiments at home and abroad...
