Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0016] like figure 1 The schematic block diagram shown in the present invention is an instrument for monitoring the abnormality of the earth microcurrent precursor, including a probe 1, a signal amplification circuit 2, a filter circuit 3, a photoelectric isolation circuit 4, and a data acquisition instrument 5 connected in sequence; the probe 1 passes through the cable The collected three-way signals are sent to the signal amplifier circuit 2, and the signal amplifier circuit 2 respectively amplifies the corresponding signals, etc. After the signal is amplified, it is input to the filter circuit 3 to filter out the noise signal, and the output terminal of the filter circuit 3 is connected to the photoelectric isolation In the circuit 4, the signal is isolated and input to the data acquisition instrument 5 for storage and transmission.

[0017] like figure 2 A...

Abstract

The invention discloses a hydropower monitoring instrument, which can monitor an abnormal earth micro current premonition. The hydropower monitoring instrument comprises a probe, a signal amplifying circuit, a filter circuit, a photoelectric isolation circuit, and a data acquisition device connected in sequence, wherein the probe is formed by a lower cone-shaped stainless steel sensing electrode and an upper cylinder-shaped wiring end, the upper cylinder-shaped wiring end introduces four electrodes respectively from top to bottom, electrodes 6 and 7 are used for monitoring resistance, electrodes 8 and 9 are used for monitoring current, and electrodes 6 and 9 are used for monitoring a potential difference. Three ways of signals sensed by the probe are transmitted to the signal amplifying circuit for processing such as amplifying via a cable, the signals are then inputted to the filter circuit, the output end is connected with the photoelectric isolation circuit, and the signals are isolated and then inputted to the data acquisition device for storage and transmission. According to the hydropower monitoring instrument, three ways of signals such as water resistance, water current and water potential difference can be detected at the same time, abnormal earthquake premonition for earth micro signals can be effectively presented, and comparative observation and data analysis are facilitated. The hydropower monitoring instrument has the advantages of simple structure, convenient mounting, saved space, high sensitivity and strong anti-interference ability.

Description

technical field [0001] The invention relates to an instrument for monitoring the abnormality of the precursor of the earth microcurrent. Background technique [0002] Earthquake is a sudden and extremely destructive natural disaster, which has the characteristics of strong suddenness, great destruction, serious secondary disasters, and great social impact. The data show that there is a certain micro-current in the earth due to the ionization caused by the radiation of radioactive substances. Under the action of the stress field before the earthquake, the piezoelectric effect occurs when the rock mass is squeezed, resulting in an abnormal micro-current. The abnormal monitoring of the micro-current in groundwater, It is a more effective way to observe earthquake precursors. At present, only a single method is used to monitor the change of microcurrent in groundwater for the monitoring of ground microcurrent, and there is a lack of comparative observation with other physical q...
