Description

Technical Field

[0001] This invention belongs to the field of seismic exploration and development of minerals, oil and gas, shale oil and gas and coalbed methane, and more specifically, relates to a data time-division transmission method, system, device and computer-readable storage medium. Background Technology

[0002] The instrument used to record seismic waves is called a seismograph, which objectively and promptly records ground vibrations. Its basic principle is based on the inertia of a suspended weight; when an earthquake occurs, the ground vibrates while the weight remains stationary. The vibrations recorded by the seismograph are a curve with varying amplitudes, called a seismic spectrum. The amplitude of the curve corresponds to the amplitude of the ground vibrations caused by the seismic waves, indicating the intensity of the earthquake. The effects of different types of seismic waves can be clearly distinguished from the seismic spectrum. The time difference between P-waves and S-waves arriving at the same seismic station, i.e., the time difference, is directly proportional to the distance from the epicenter to the seismic station; the farther away from the epicenter, the greater the time difference. From this law, the distance from the epicenter to the seismic station, i.e., the epicentral distance, can be calculated.

[0003] In recent years, nodal seismometers have increasingly appeared in the field of geophysical exploration due to their flexibility, low cost, and high efficiency. Currently, most existing nodal seismometers operate in blind acquisition mode (only acquiring signals during operation, without transmitting data), and then transmit the data back via wired connection after the signal acquisition is completed. Wireless data transmission nodal seismometers, on the other hand, can utilize wireless communication technology to transmit data back in real time.

[0004] Existing wireless data transmission node seismographs require related hardware to operate in wireless real-time data transmission mode. Continuously keeping this hardware powered on for data transmission will greatly increase the power consumption of the wireless data transmission node seismograph. Since most existing wireless data transmission node seismographs are battery powered, this wireless real-time data transmission mode will have a significant impact on the battery life of the wireless data transmission node seismograph. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of short battery life of existing wireless data transmission type node seismographs.

[0006] To achieve the above objectives, the present invention provides a data time-division transmission method, system, device, and computer-readable storage medium.

[0007] According to a first aspect of the present invention, a time-division multiplexing method for data transmission is provided, the method being applied to a wireless data transmission device, the wireless data transmission device comprising a timing unit and a transmission unit;

[0008] The time-division data transmission method includes the following steps:

[0009] Set the time interval for data transmission;

[0010] Set the cycle time interval of the timing unit to be the same as the time-division interval, and start the timing unit;

[0011] In response to the instruction issued by the timing unit to execute once, the transmission unit is started and the transmission unit is controlled to perform a predetermined handshake strategy with the data receiving end;

[0012] If the transmission unit successfully hands with the data receiving end, it controls the transmission unit to communicate with the data receiving end for a predetermined duration and then closes the transmission unit after the predetermined duration.

[0020] Preferably, the handshake strategy includes:

[0021] The transmission unit and the data receiving end perform a first handshake. If the handshake fails, the first handshake will randomly back off for a period of time.

[0022] After the first time rollback ends, the transmission unit and the data receiving end perform a second handshake. If the handshake fails, the second rollback will randomly roll back for a period of time.

[0023] After the second time rollback ends, the transmission unit and the data receiving end perform a third handshake. If the handshake fails, the transmission unit abandons the communication connection request.

[0024] Preferably, the duration of each random rollback does not exceed the predetermined maximum rollback duration.

[0025] Preferably, after the transmission unit establishes a communication connection with the data receiving end, the data receiving end obtains the authority to send new instructions to the transmission unit.

[0026] The new instruction message includes a frame header, node ID, command code, parameters, checksum, and end character;

[0030] The first module is used to set the time interval for data transmission;

[0031] The second module is used to set the cyclic time interval of the timing unit to be the same as the time-division interval, and to start the timing unit;

[0032] The third module is used to respond to the instruction issued by the timing unit to execute once, start the transmission unit and control the transmission unit to perform a predetermined handshake strategy with the data receiving end;

[0033] The fourth module is used to control the transmission unit to communicate with the data receiving end for a predetermined duration and then shut down the transmission unit after the predetermined duration if the handshake between the transmission unit and the data receiving end is successful.

[0036] The beneficial effects of this invention are as follows:

[0037] The data time-division transmission method of the present invention first sets a time-division interval for data transmission; secondly, it sets the cycle time interval of the timing unit to be equal to the time-division interval and starts the timing unit; when the timing unit completes one cycle time interval and issues an execution command, it starts the transmission unit and controls the transmission unit to perform a predetermined handshake strategy with the data receiving end; when the transmission unit and the data receiving end successfully handshake, it controls the transmission unit to communicate with the data receiving end for a predetermined duration and then shuts down the transmission unit after the predetermined duration. The data time-division transmission method of the present invention achieves data time-division transmission for wireless data transmission node seismographs through the above steps, thereby reducing the power consumption of the wireless data transmission node seismograph to a certain extent and increasing its battery life.

[0043] Example 1: Figure 1 A flowchart illustrating the implementation of the time-division multiplexing data transmission method according to an embodiment of the present invention is shown. (Refer to...) Figure 1 The data time-division transmission method of this invention is applied to a wireless data transmission device, which includes a timing unit and a transmission unit.

[0044] The data time-division transmission method of this invention includes the following steps:

[0045] Step S100: Set the time interval for data transmission;

[0046] Step S200: Set the cyclic time interval of the timing unit to be the same as the time-division interval, and start the timing unit;

[0047] Step S300: In response to the instruction issued by the timing unit to execute once, start the transmission unit and control the transmission unit to perform a predetermined handshake strategy with the data receiving end;

[0048] Step S400: If the transmission unit successfully hands with the data receiving end, control the transmission unit to communicate with the data receiving end for a predetermined duration and then close the transmission unit after the predetermined duration.

[0049] Specifically, in this embodiment of the invention, the wireless data transmission device is a wireless data transmission type nodal seismograph.

[0050] Furthermore, before setting the time-division interval for data transmission in step S100, the data time-division transmission method of this embodiment of the invention further includes the following steps:

[0051] Set multiple different time interval options.

[0052] Furthermore, in this embodiment of the invention, the setting of the time interval for data transmission in step S100 specifically refers to:

[0053] Based on the application scenario requirements of the wireless data transmission device, the time interval for data transmission is selected from the multiple different time interval options.

[0054] Specifically, in this embodiment of the invention, a time interval D is set according to the scenario requirements. is When setting the interval, pay attention to the lower limit D. low Based on the startup time of the entire data transmission equipment, it can be set to D. is = 10 minutes. The typical time interval is D. is = 30 minutes, 60 minutes or 120 minutes.

[0055] Specifically, the wireless data transmission type node seismograph sets the timer Time so that the timer cycle time is equal to the time interval, i.e., Time = D. is When the timer completes one cycle interval, the wireless data transmission node seismograph starts its transmission unit.

[0056] Furthermore, the data time-division transmission method of this embodiment of the invention also includes:

[0057] If the number of consecutive handshake failures between the transmission unit and the data receiving end reaches a predetermined failure threshold, the transmission unit is shut down.

[0058] Furthermore, in step S300 of this embodiment of the invention, the handshake strategy includes:

[0059] The transmission unit and the data receiving end perform a first handshake. If the handshake fails, the first handshake will randomly back off for a period of time.

[0061] After the second time rollback ends, the transmission unit and the data receiving end perform a third handshake. If the handshake fails, the transmission unit abandons the communication connection request.

[0062] If any handshake is successful during the above process, step S400 is executed.

[0063] Furthermore, in this embodiment of the invention, the duration of each random rollback does not exceed a predetermined maximum rollback duration, which is 20 seconds.

[0064] Specifically, in this embodiment of the invention, the data receiving end is a remote server. When the wireless data transmission node seismograph starts its transmission unit, it begins data transmission with the remote server. However, unexpected situations may occur during transmission, leading to connection failures. Therefore, the time-division multiplexing data transmission method of this embodiment employs the aforementioned handshake mechanism to minimize connection failures.

[0065] Furthermore, in this embodiment of the invention, in time-division mode, the wireless data transmission node seismograph cannot obtain any new instructions when it is not transmitting; new instructions need to be obtained after establishing a connection at each time-division interval.

[0067] The new instruction message includes a frame header, node ID, command code, parameters, checksum, and end character;

[0068] The frame header is "$" and occupies 1 byte, the node ID occupies 8 bytes, the command code occupies 2 bytes, the checksum occupies 1 byte, and the terminator is "\r\n".
