Description

Technical Field

[0001] The invention relates to the technical field of induced polarization detection, and in particular to a system for improving the resolution of shallow parts of induced polarization detection. Background Art

[0002] In the search for metal sulfide minerals, the induced polarization method (IPM) is irreplaceable. However, with the increase of exploration depth, the resolution of the shallow part decreases due to the limitation of the device. Mines often have better control over the shallow part due to the geological engineering construction. If the resolution of the shallow part of the depth measurement result is too low, it will not correspond well to the geological conditions. It is necessary to improve the resolution of the shallow part of IP depth measurement.

[0003] Conventional IP exploration depth is less than 500 meters. If the IP work needs to be deeper than 500 meters, it is time-consuming and laborious to use manual pole running measurement. This is due to the device. Time series receivers are required to automatically collect data. Fixed measurement of time series receivers cannot automatically jump to change the pole distance size.

[0004] The signal of deep exploration is small and the interference is large, so high-precision imported instruments are needed for measurement. However, imported instruments are expensive and difficult to maintain, so they cannot be purchased in large quantities. Summary of the invention

[0005] The purpose of the present invention is to provide a system for improving the resolution of shallow parts of induced polarization depth measurement, so as to solve the technical problem of high production cost of personnel and equipment investment proposed in the background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A system for improving the shallow resolution of induced polarization depth measurement includes a controller, a GPS, and a relay. After the GPS positioning is successful, the time is granted to the controller. The relay includes 3 input terminals and two output terminals. The controller controls the relay to automatically switch channels through a single-chip microcomputer with a cycle of 10 minutes. The GPS timing module and the embedded controller control the system according to the embedded program. The system configures and receives GPS information through a serial port, interprets the time and grants the system, and realizes the time synchronization of multiple systems.

[0008] Preferably, the relay comprises three input terminals A, B, C and two output terminals 1, 2. Input terminals A and B are connected to output terminals 1 and 2 in 1-3 minutes, input terminals B and C are connected to output terminals 1 and 2 in 4-6 minutes, and input terminals A and C are connected to output terminals 1 and 2 in 7-10 minutes.

[0009] Preferably, the relay model is TQ2-L2_12V, and an optocoupler isolation relay is used.

[0010] Preferably, the controller is a 32-bit ARM processor, the chip model is GD32F103rct6, and the main frequency is 120MHz.

[0011] A method for improving the resolution of shallow parts of induced polarization depth measurement, comprising the following steps:

[0012] 1) Arrange the converter system and IP receiver according to the construction design;

[0013] 2) Turn on the converter system to receive GPS satellites and wait for GPS to stabilize;

[0014] 3) After the converter system time is synchronized, the channel is automatically switched in a cycle of 10 minutes;

[0015] 4) After completion, extract the time series data of the IP receiver, extract the data of 1-3 minutes, 4-6 minutes and 7-10 minutes respectively, and use the fullwave geophysical prospecting professional software to extract the data. After obtaining all the collected data, perform data analysis and processing, calculate the apparent resistivity and polarizability values, use RES2DINV software, and use the minimum curvature method or Kriging interpolation method to perform grid calculations, and finally complete the inversion interpretation.

[0016] The present invention has at least the following beneficial effects:

[0017] The invention is easy to operate and can automatically switch channels. Multiple systems can switch channels according to GPS time, which is convenient for batch processing of data collected by IP receivers, reduces labor intensity and avoids human error. Similarly, the use of this system only requires half of the IP receivers, which can reduce the purchase of expensive instruments and reduce production costs and personnel costs.

[0020] Example

[0021] like Figure 1 As shown, a system for improving the shallow resolution of induced polarization depth measurement includes a controller, a GPS, and a relay.

[0022] The controller (MCU) uses GigaDevice's 32-bit ARM processor, the chip model is GD32F103rct6, the main frequency of 120MHz is sufficient for this system, and the chip has rich peripheral resources.

[0023] MCU is the brain of the whole system, controlling and configuring peripherals. After successful GPS positioning, the system is granted time. The single-chip microcontroller automatically switches relays to facilitate switching between different channels. Specifically, according to a 10-minute cycle, 0-3 minutes connect input A and B with output 1 and 2, 4-6 minutes connect input B and C with 1 and 2, 7-10 minutes connect input A and C with output 1 and 2 (such as Figure 1 Thus, one emission point every 10 minutes not only increases the exploration depth but also enhances the resolution of shallow areas.

[0024] The relay uses optocoupler isolation to improve system stability. The relay uses signal relay to reduce volume and power consumption.

[0025] The present invention also provides a method for improving the resolution of the shallow part of the induced polarization depth measurement system, comprising the following steps:

[0026] 1) Arrange the converter system and IP receiver according to the construction design;

[0027] 2) Turn on the converter system to receive GPS satellites and wait for GPS to stabilize;

[0028] 3) After the converter system time is synchronized, the channel is automatically switched in a cycle of 10 minutes;

[0029] 4) After completion, extract the time series data of the induced polarization receiver, and extract the data of 1-3 minutes, 4-6 minutes and 7-10 minutes respectively. Taking the period of 00:00-00:10 as an example, the three data segments of 00:00-00:03, 00:03-00:06, and 00:06-00:10 can be extracted using the fullwave geophysical prospecting professional software, and so on. After obtaining all the collected data, after data analysis and processing, the apparent resistivity and polarizability values ​​are calculated, and the Swedish RES2DINV software is used to perform grid calculations using the minimum curvature method or Kriging interpolation method to finally complete the inversion interpretation.
