The financial shared service model now has a technological base thanks to recent advancements in the information technology sector. Cloud computing, big data, and other technologies are included. To some extent, it has produced the current financial shared service model. This service model not only realizes the front-end information input but also ensures the specialization of financial data. The business data provided from the front end may be translated into the financial data required by finance using the enterprise resource planning (ERP) system. It overcomes the drawbacks of the existing financial system while also increasing its operating efficiency. The financial sharing service offers a high level of standardization of financial procedures while simultaneously lowering financial management costs. This allows the enterprise group to handle the financial systems of its subsidiaries in a uniform manner. It promotes the transparency of financial information, improves the overall competitive level of the enterprise group, and creates huge economic benefits for the enterprise group. Therefore, in the current operation stage of enterprises, the method of using the scientific service mode to maximize the economic benefits of enterprises has become an important problem. It is unlikely that understanding how to utilize it appropriately will have an impact on business operations. To ensure that enormous volumes of data are sent in an efficient and reliable manner, Gigabit Ethernet is used for the data transmission interface in this paper. On the one hand, an application layer user-defined protocol is meant to provide data transfer with high efficiency, speed, and reliability, while, on the other hand, on the basis of interface hardware program design, it is proposed to complete the modular design through the packaging of P core. It is the hardware foundation for interface data transfer. Finally, tests to validate its efficiency, speed, and dependability are devised.

“…The acoustic experiments were conducted in a water tank with the dimensions of 5.0 m × 5.0 m × 4.0 m. The fluid density and velocity were 1000 kg/m 3 and 1500 m/s, respectively. As shown in Figure 4 , the experimental apparatus included an electrical excitation resource, cylindrical transmitter, host computer, positioning control system, multichannel acquisition system, gain-controlled amplifier, and hydrophone [ 18 , 19 ]. The excitation resource produced high-voltage pulses to emit the transducer and synchronize signals to start the high-accuracy synchronous data acquisition system.…”

Array transducer and transducer combination technologies are evolving rapidly. While adapting transmitter combination technologies, the parameter consistencies between each transmitter are extremely important because they can determine a combined effort directly. This study presents a consistency evaluation and calibration method for piezoelectric transmitters by using impedance analyzers. Firstly, electronic parameters of transmitters that can be measured by impedance analyzers are introduced. A variety of transmitter acoustic energies that are caused by these parameter differences are then analyzed and certified and, thereafter, transmitter consistency is evaluated. Lastly, based on the evaluations, consistency can be calibrated by changing the corresponding excitation voltage. Acoustic experiments show that this method accurately evaluates and calibrates transducer consistencies, and is easy to realize.

“…Currently, most acoustic well logging transmitting transducers are fired by single-pulse excitation circuits, whose advantage is their simple structure and wide frequency band [ 28 , 29 , 30 , 31 ]. Meanwhile, the acoustic signal frequencies excited by these circuits is not adjustable, and the excited transducers only work at their resonance frequencies, no matter the impulse width of the excitation signals [ 32 , 33 , 34 ].…”

To obtain qualified logging while drilling (LWD) data, a new acoustic LWD tool was designed. Its overall design is introduced here, including the physical construction, electronic structure, and operation flowchart. Thereafter, core technologies adopted in this tool are presented, such as dominant exciting wave bands of dipole source, a sine wave pulse excitation circuit, broadband impedance matching, and an intellectualized active reception transducer. Lastly, we tested this tool in the azimuthal anisotropy module well, calibration well, and normal well, working in the model of the cable, sliding eye, and logging while drilling. Experiments showed that the core technologies achieved ideal results and that the LWD tool obtained qualified data.
