A wireless data acquisition system based on MSP430F149 is developed for the measurement of microbial fuel cells’ voltage. The main function of this system is to convert the analog input voltage into digital output code, process the digital code, and transfer the data through the GSM network or the USB interface. The core of the data acquisition device is a 16-bit general purpose Texas Instruments ultralow-power microcontroller MSP430F149. As the voltage of a microbial fuel cell is very low, the A/D converter circuit is specifically designed for high precision and high accuracy. A real-time clock is used to achieve timing measurement and the time interval can be set to meet demands. The data collected is transferred through the GSM network. Besides, a Windows environment application developed with Visual C++ can be used to access the data stored in the flash memory through USB interface.

A MEMS air pressure sensor system is proposed in the paper, which can monitor the air pressure by means of measuring the discharge time of the sensor. The system contains two parts: the MEMS air pressure sensor and the data acquisition system. The MEMS air pressure sensor is an enhanced pizeoresistive pressure sensor. The data acquisition system contains a time-to-digital part, which measures time interval by using of the propagation delays of logical gates. The time-to-digital part can measure the resistors’ discharge time and turn it into digital output, when the resistors on the air pressure sensor are connected to a capacitor which is full of charge. The discharge time is only related to the resistor, and then the pressure measurement is changed to time measurement. The digital output is shown through a liquid crystal display screen.

The paper introduces the status of rolling bearing life testing machine in China first. Then, the paper mainly focuses on the design of vibration signal data acquisition system for rolling bearing life testing machine. The system is developed for a rolling bearing manufacturer based on Labview with perfect functions according to the requirement of the customer. The rolling bearing manufacturer can set up different measurement time and time interval for data record to carry out test according to the requirement of its customers. The developed vibration signal acquisition system is not subject to testing machine, which can run only that the sensors are installed on the measurement locations of testing machine. The developed system can be used for different rolling bearing life testing machine, so it has good application perspective in future.

Abstract An embedded time interval data acquisition system (DAS) is developed for zero power reactor (ZPR) noise experiments. The system is capable of measuring the correlation or probability distribution of a random process. The design is totally implemented on a single Field Programmable Gate Array (FPGA). The architecture is tested on different FPGA platforms with different speed grades and hardware resources. Generic experimental values for time resolution and inter-event dead time of the system are 2.22 ns and 6.67 ns respectively. The DAS can record around 48-bit x 790 kS/s utilizing its built-in fast memory. The system can measure very long time intervals due to its 48-bit timing structure design. As the architecture can work on a typical FPGA, this is a low cost experimental tool and needs little time to be established. In addition, revisions are easily possible through its reprogramming capability. The performance of the system is checked and verified experimentally.
