Description

Technical Field

[0001] This application relates to the field of seismograph technology, and in particular to a controllable source system. Background Technology

[0002] Currently, in the field of seismic exploration, controlled seismic sources are widely used for seismic data acquisition. With the development of my country's petroleum industry, field testing of seismographs generally employs manual blasting or vehicle-mounted controlled seismic sources. Most controlled seismic sources are currently large vehicle-mounted sources, which are bulky and require specific site conditions, such as flat, open areas. Furthermore, transportation and use are costly in terms of manpower and resources. Seismic sources typically use heavy hammers or explosives; however, explosive sources pose hidden hazards to surrounding people and buildings and are prohibited in densely populated areas. Vehicle-mounted seismic sources generate seismic waves by continuously impacting the ground with a vibrator mounted on a special vehicle. These methods are expensive and cannot easily access mountainous or basin-like work areas. Additionally, the blasting times recorded by these methods are not precise enough, and the operation is time-consuming and labor-intensive, often failing to achieve the desired results.

[0090] Example 4

[0091] Based on the foregoing embodiments, this application provides a controllable seismic source system, including:

[0092] The system comprises a control system, a stepper motor driver, a stepper motor, and a vibration source system. The control system (ARM microcontroller) includes an MCU module, a GPS module, and a Bluetooth module.

The ARM microcontroller is used to implement the following functions of the hardware device: 1) Manual vibration (vibration upon pressing); 2) Autonomous vibration (with configurable vibration start time st, vibration interval i, and vibration count tk); 3) Retrieving vibration time data for the current day.

[0093] The implementation steps of the technical solution are as follows:

[0094] Step 1: The Bluetooth receiving terminal device sends a command;

[0095] Step 2: The command is parsed to obtain the vibration start time st, vibration interval i, and vibration count tk;

[0096] Step 3: Open serial port 3 to receive GPS signals;

[0098] Step 5: Turn on the Timer to start timing. Based on the internal timer, when the vibration time interval i is reached, the GPIO port sends a control signal to turn on the vibration source. The current UTC time is stored in the SD card, and then waits for the next vibration interval i.

[0099] Step 6: The autonomous vibration ends when the number of vibrations meets the command setting tk, and the vibration time file is saved and named with the date of the day.
