Computerized well logging equipment plays an important role in petroleum exploration and production, and data acquisition system is the core of it. In order to improve the acquisition systems which are used in some oil fields in recent years, a new design of data acquisition system is introduced. The ARM embedded chip and the FPGA chip are the kernel chips of the data acquisition system, and the Ethernet is the communication medium between the cards of the data acquisition system and the host computer of the numerical controlled well logging system. This data acquisition system has more integrated level and communication speed higher than the others of same kind.

Practical Design

The trend in industrial control has been to reduce the communications wiring across a plant. Eliminating the cabled connection between a sensors and a host computer enhances the performances and the manageability of a data acquisition system. Through the use of Bluetooth technology the data acquisition components can be paired with a wide variety of pre-existing devices. This makes the host computer portable, cheaper and versatile. Data is collected from the sensors by a microcontroller with an attached Bluetooth module, which transmits the data to a host computer for processing. Costs are reduced by making use of pre-existing processing power and display on the host computer. Depending on the application the data can be processed in any way required on the host computer. This paper describes the practical design of Bluetooth based 12- Channel temperatures acquisition system which contains remote temperature sensors connected to a microcontroller which controls also the Bluetooth module transmission, and a computer connected to a Bluetooth adapter. In this way, the sensors data are collected and processed by the microcontroller, transmitted via Bluetooth to a host computer which monitoring and recording the temperatures measurements.

Lock In

In most Terahertz time-domain spectrometer (THz-TDS) experiments, the lock-in amplifier works with trans-impedance pre-amplifier to amplitude the terahertz pulse accepted from detector. This paper discusses the development of data acquisition system for the transmission THz-TDS. In this system, the cross-correlation software algorithm in SR830 lock-in amplifier from Stanford Research Systems, that is usually used in THz-TDS, has been replaced by parallel hardware algorithm of Field Programmable Gate Array (FPGA) chip with the parallel processing ability. This chip has a faster processing speed and higher accuracy than others. A 24 bit Delta-Sigma Analog Digital (AD) was used in place of the 16 bit successive approximation ADC of SR830. The new AD convertor can reduce the complexity of trans-impedance pre-amplifier circuit and replace the SR555 current amplifiers that designed to work with SRS lock-in amplifiers. Besides trans-impedance pre-amplifier circuit, all function circuits, such as low-pass digital filter, phase-locked loop, Direct Digital Synthesis (DDS) reference source and the core algorithms, are integrated in a FPGA chip, which make the new designed lock-in amplifier with a small volume reduce a dozen times SR830 size.

Maintenance Program

This paper describes the development of a portable data acquisition system for use in a plant-wide, predictive maintenance program for rotating machinery. Designed to replace hand-logging and other clipboard surveillance methods, the portable instrument stores the measured parameters in digital memory for transfer to a desktop host computer for processing and analysis. Developments in electronics and computer technology as well as preventive/predictive maintenance procedures have made this instrument system possible. These developments are outlined, along with a discussion of the operation and use of the system.

Wireless Data Acquisition

This paper presents a design of wireless data collector based on WIA-PA. The wireless data collector collects analog signal of voltage or current, and transmits it to the host computer wirelessly. Through it, the traditional 4-20mA or 0-5V analog interfaced instrument can be easily accessed to the newly designed wireless data acquisition system, which saves wiring and maintenance costs.

Although microbial biosensor can be used for online monitoring, its application is limited due to the data acquisition and transmissions are difficult. This paper presents a wireless high-precision microbial biosensor data acquisition system. It is constructed with CC2530 as the core chip, while NUC120, PGA280 and ADS1259 as supplemented chips. Software design uses C and LabVIEW. Because of wireless transmission, the system can availably solve wiring problem of special environment and is easy to connect to the Internet. It expands the application scope of microbial biosensor effectively, and can be widely used in all kinds of small data acquisition fields which require high-precision.
