Description

Technical Field

[0002] Fifth-generation mobile communication technology (5G) is a wireless mobile communication system developed in response to the growing demand for mobile data in the information society. It is a network that integrates multiple service technologies and, through technological evolution and innovation, meets the ever-evolving needs of various services such as data and connectivity in the future.

[0003] As new geophysical acquisition technologies such as "wide-area, high-density, and high-precision" acquisition mature and are widely adopted, these technologies and methods place higher demands on acquisition equipment. High-density acquisition can significantly improve data quality. However, with the continuous expansion of exploration areas, complex terrain makes mechanized construction difficult, leading to a growing demand for geophysical equipment that utilizes new technologies, improves efficiency, is modular, and lightweight. Currently, electromagnetic data acquisition instruments available for mass production all employ a blind acquisition method, meaning data is collected and stored locally. The actual data is only available after the instrument is returned to the camp and downloaded, resulting in a significant gap between the timeliness required by customers and reality.

[0055] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0056] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0057] Based on the above objectives, a first aspect of the present invention provides an embodiment of an electromagnetic data acquisition instrument. The electromagnetic data acquisition instrument includes:

[0058] The housing includes a communication circuit board and a data acquisition and control circuit board disposed within the housing. The communication circuit board and the data acquisition and control circuit board are connected via a network.

The battery pressure plate 306 is located between the data acquisition control circuit board 305 and the battery pack 308, isolating them and protecting them. The shock-absorbing foam, located at the bottom of the housing, absorbs vibrations for the entire instrument and provides protection for the internal components in the event of a drop.

[0063] The housing includes an upper housing 301 and a lower housing 310. The lower edge of the upper housing 301 is pressed into the upper edge of the lower housing 310.

[0066] In some embodiments, the communication circuit board includes a communication circuit module, which includes a communication module and a first network physical layer chip connected to the communication module.

[0067] The communication module is used to convert the wired network provided by the first network physical layer chip into a wireless network, and then receive or send data.

[0068] The communication module is also used to establish a network communication connection with the acquisition and control circuit module through the first network physical layer chip.

[0069] In some embodiments, the communication circuit module further includes a radio frequency antenna and a first power supply module connected to the communication module. The radio frequency antenna is used to convert the wired network into a wireless network, and the first power supply module is used to supply power to the communication module.

[0070] In some implementations, the communication module is provided with a PCIe interface, a USB interface, and a general serial port;

[0071] The communication module is used to connect to the first network physical layer chip through the PCIe interface;

[0074] The communication module is used to connect to a computer device via the general serial port for debugging the functions of the communication module.

[0075] like Figure 2 The diagram shown is a schematic of the communication circuit module of the electromagnetic acquisition instrument.

[0076] The communication circuit module of the electromagnetic data acquisition instrument is developed based on the 5G wireless communication module 11. The 5G wireless communication module 11 contains various peripheral interfaces, such as USB 2.0, general serial ports, and PCIe interfaces. The PCIe interface of the 5G wireless communication module 11 is connected to the network physical layer chip 12, converting its communication protocol from the PCIe interface to a network interface, enabling network communication between the communication circuit module and the acquisition control circuit module of the electromagnetic data acquisition instrument. Based on the usage requirements of the 5G wireless communication module 11, a four-channel antenna circuit is designed to connect to radio frequency antennas, converting the wired network signal of the 5G wireless communication module 11 into a wireless network signal, enabling remote wireless signal transmission.

[0077] The USB 2.0 interface of the 5G wireless communication module 11 is used for firmware upgrades and AT command configuration. The general-purpose serial port of the 5G wireless communication module 11 enables debugging functions. The first power module 15 provides a stable and reliable voltage input to the module 11.

[0078] In some embodiments, the acquisition control circuit board includes an acquisition control circuit module, which includes a central control unit and a second network physical layer chip that is communicatively connected to the central control unit.

[0079] The central control unit is used to connect to the first network physical layer chip through the second network physical layer chip to realize network communication connection with the communication circuit module;

[0080] The central control unit is also used to set the electromagnetic acquisition instrument as a client after connecting to the Ethernet via the second network physical layer chip, and to connect to the remote server based on the dynamic IP after obtaining the dynamic IP through the communication circuit module.

[0081] The central control unit is also used to perform corresponding operations based on instructions issued by the remote server.

[0082] like Figure 3 The diagram shown is a schematic of the acquisition control circuit module of an electromagnetic acquisition instrument.

[0083] The acquisition and control circuit module of the electromagnetic data acquisition instrument is developed based on a central control unit. It internally includes various peripheral interfaces such as a general-purpose serial port, a serial peripheral interface (SPI), an SDIO interface, an RMII interface, and an FSMC interface. The central control unit's hardware program is used to program the timing of I / O pin control, the general-purpose serial port, the FSMC interface, the RMII network, the SDIO interface, and the SPI interface to achieve connection with peripheral devices. The central control unit connects to the second network physical layer chip 27 via the RMII interface to achieve network communication with the communication circuit module. The central control unit implements the TCP / IP protocol through hardware programming, setting the electromagnetic data acquisition instrument as a client. After connecting to the communication circuit module, network switch, or router, it obtains a dynamic IP address and actively connects to a remote server based on the dynamic IP address, enabling real-time control of the electromagnetic data acquisition instrument through the remote server.

[0084] Connect the general-purpose serial port of the central control unit to the general-purpose serial port 22 of the computer device for debugging output of the time and frequency acquisition instrument. Specifically, the acquisition control circuit module is debugged by using the hardware program on the computer device and outputting the set string through the general-purpose serial port, which simplifies the debugging process of the electromagnetic acquisition instrument.

[0085] In some embodiments, the data acquisition and control circuit module further includes an analog-to-digital converter module that is communicatively connected to the central control unit, the analog-to-digital converter module being used to acquire data.

[0086] In some embodiments, the acquisition and control circuit module further includes a GPS module that is communicatively connected to the central control unit;

[0087] The central control unit is also used to acquire the current time information, second pulse signal and 3D lock status through the GPS module, and after acquiring the 3D lock status as locked, write the time information into the clock system based on the next acquired second pulse signal.

[0088] Specifically, the central control unit communicates with the GPS module 23 via a general-purpose serial port to obtain the current time information, geographical location information, and second pulse, using the time information as the system's time reference. The specific process is as follows: the GPS module continuously outputs information such as time, geographical location, and 3D lock status to the central control unit via the general-purpose serial port. When the central control unit obtains the time information via the general-purpose serial port and parses it to determine that the GPS module 23 is in a locked state, it writes the time information into the clock system as the reference time for the electromagnetic acquisition instrument when the next second pulse signal appears.

[0089] In some embodiments, the acquisition and control circuit module further includes an FPGA communicatively connected to the central control unit, a temperature-controlled crystal oscillator module connected to the FPGA, and at least one analog-to-digital converter module;

[0090] The FPGA is used to transmit the data collected by the analog-to-digital conversion module to the central control unit;

[0091] The FPGA is also used to acquire the second pulse signal through the GPS module, and to calibrate the thermostatic crystal oscillator module based on the second pulse signal and lock the clock system after calibration.

[0092] Specifically, after receiving the second pulse, the FPGA chip 24 calibrates the temperature-controlled crystal oscillator module. Once the temperature-controlled crystal oscillator module stabilizes, it determines that the clock system of the electromagnetic acquisition instrument is locked. The specific process is as follows: After receiving the second pulse, the FPGA chip starts counting on the rising edge of the second pulse. If the count value on the rising edges of two consecutive second pulses is equal to the rated frequency of the temperature-controlled crystal oscillator, it is determined that the clock system of the electromagnetic acquisition instrument is locked.

[0093] The analog-to-digital converter module 25 is used for data acquisition. The FPGA chip 24 connects to the SPI interface of the central control unit and the two analog-to-digital converter modules, achieving the effect of splitting one SPI interface into two SPI interfaces. The specific process is as follows:

[0094] The FPGA uses its internal programmable logic gates to select only one of the two signals from the connected analog-to-digital converter module. The selected information can then be used for normal communication, thus enabling the SPI interface to convert one signal to two.

[0095] In some embodiments, the acquisition and control circuit module further includes a first storage module, a second storage module, and a second power supply module connected to the central control unit;

[0096] The central control unit is also used to buffer and store the received collected data into the first storage module;

[0097] The central control unit is also used to package the received collected data and store it in the second storage module;

[0098] The second power module is used to supply power to the central control unit.

[0099] Specifically, the central control unit connects to the SD storage module via the SDIO interface, packages the collected data, and stores it in a designated path and file within the SD card. More specifically, the central control unit uses the SDIO interface and the FATFS file system to enable file and folder storage within the SD card, supporting long filenames.

[0100] The central control unit is connected to the static random access memory (SRAM) 29 via the FSMC interface, and uses the SRAM memory as a buffer for data acquisition.

[0101] The second power module 28 provides a stable and reliable voltage output for the system.

[0102] In some implementations, the first storage module includes a static random access memory, the second storage module includes a memory card, the communication module includes a 5G communication module, and the operation includes real-time data acquisition.

[0103] In some embodiments, the housing is further provided with a pressure plate, a battery pressure plate, and a battery pack, wherein the pressure plate, the communication circuit board, the acquisition and control circuit board, the battery pressure plate, and the battery pack are arranged sequentially from top to bottom.

[0104] In some embodiments, the housing is further provided with a first line protection pad, a second line protection pad, a first shock-absorbing foam, and a second shock-absorbing foam. The first line protection pad is located between the pressure plate and the communication circuit board, the second line protection pad is located between the communication circuit board and the acquisition and control circuit board, the first shock-absorbing foam is located between the battery pressure plate and the battery pack, and the second shock-absorbing foam is located below the battery pack.

[0105] In some embodiments, the housing includes an upper housing and a lower housing, the upper housing and the lower housing being fixedly connected by fasteners;

[0106] The first side of the inner wall of the lower housing is provided with multiple contacts, which are used for local network connection of the electromagnetic acquisition instrument and / or output of serial port signals and / or charging of the battery pack.

[0107] The second side of the inner wall of the lower housing, opposite to the first side, is provided with a signal source interface and a serial port interface. The signal source interface is used to connect to a signal source device, and the serial port interface is used to connect to a computer device.

[0108] Based on the same inventive concept, according to another aspect of the present invention, such as Figure 4 As shown, embodiments of the present invention also provide a data acquisition method for an electromagnetic acquisition instrument, the method specifically including:

[0109] S10. The clock system of the electromagnetic acquisition instrument is calibrated, and the dynamic IP is obtained after the clock system calibration is completed;

[0110] S20. Establish a connection between the electromagnetic acquisition instrument and the remote server based on the dynamic IP;

[0111] S30. After the electromagnetic acquisition instrument establishes a connection with the remote server, it receives instructions from the remote server and performs corresponding operations.

[0112] Specifically, in step S10, the central control unit parses the information output by the GPS module, extracting time information, geographic location information, and 3D lock information. If the GPS module is in 3D lock mode, the FPGA is used to calibrate the temperature-controlled crystal oscillator module, and the time information is written into the acquisition instrument as the reference time. The geographic location information is used for positioning of the electromagnetic acquisition instrument.

[0113] In step S20, after powering on, the electromagnetic acquisition instrument obtains a dynamic IP through a 5G signal base station and actively connects to a remote server based on the dynamic IP to receive instructions and configuration parameters issued by the remote server.

[0114] In step S30, after establishing a connection with the remote server, the electromagnetic data acquisition instrument waits for instructions from the remote server. Upon receiving the instructions or configuration parameters, it parses the information and performs corresponding operations. These operations include, but are not limited to: remote viewing of the electromagnetic data acquisition instrument's parameters, real-time positioning, remote distribution of acquisition parameters, remote real-time data retrieval, real-time data waveform display, real-time storage of acquired data, remote sleep and wake-up, and remote download of acquired data. After completing the received instructions and corresponding operations, the electromagnetic data acquisition instrument waits for the next instruction from the remote server.

[0115] The electromagnetic data acquisition instrument of the present invention can not only acquire data, but also be controlled in real time.

[0116] In some embodiments, prior to the calibration step of the clock system of the electromagnetic acquisition instrument, the method further includes:

[0117] Initialize the electromagnetic acquisition instrument.

[0118] In some implementations, initializing the electromagnetic acquisition instrument includes initializing the central control unit and the FPGA.

[0119] Specifically, by running the application program inside the central control unit, the debug serial port and SDIO interface of the central control unit are initialized; the firmware directory inside the SD card is scanned to determine if there is new central control unit firmware. If so, the firmware is updated, and after the update is completed, the process jumps to the application program; otherwise, it jumps directly to the application program. After jumping to the application program, the central control unit initializes its functional pins, reads the parameter storage file inside the SD card and configures the default parameters of the functional pins. At the same time, the firmware directory inside the SD card is scanned to determine if there is new FPGA firmware. If so, the firmware is updated; otherwise, the process is skipped. This completes the initialization of the central control unit and the FPGA.

[0120] In some embodiments, calibrating the clock system of the electromagnetic acquisition instrument includes:

[0121] The central control unit obtains the current time information, second pulse signal and 3D lock status from the GPS module, and after obtaining the 3D lock status as locked, writes the time information into the clock system based on the next obtained second pulse signal.

[0122] In some embodiments, calibrating the clock system of the electromagnetic acquisition instrument includes:

[0123] The FPGA acquires the second pulse signal from the GPS module, and the temperature-controlled crystal oscillator module is calibrated based on the second pulse signal. After the calibration is completed, the clock system is locked.
