The Cost

Advancements in electronics provide a vital new option for implementation of low-frequency smart sensors that can perform signal processing close to the sensors and transmit the data wirelessly. These smart sensors can improve the efficiency of an automatic classification system and reduce the cost of actual infrasound microphones. The design of a digital wireless data acquisition system using a QF4512 programmable signal converter from Quickfilter Technologies, a MSP430 microcontroller from Texas Instruments and a F2M03GLA Bluetooth module from Free2move for infrasonic records is presented in this paper. The digital wireless data acquisition system has passed extensive laboratory and field tests (e.g. with man-made explosions).

The Cost

In order to overcome the disconnection and high cost and maintenance difficulties of the conventional data collection systems for structure monitoring of long span bridge, we developed a low-cost and effective data acquisition system composed of several wireless communication modules connected to vibrating wire type sensors. This system has the function to change conventional wire-based data collector into wireless one instantly. The prototype of wireless data acquisition system for vibrating sensors is described in this paper. Laboratory tests demonstrate that the wireless data acquisition system is of high accuracy and good stability. In addition, the application of this system to the strain monitoring of a large steel box arch shows the wireless data acquisition system with good performance improve the efficiency of data acquisition and reduces the cost of monitoring.

New Type

This paper puts forward a new type of wireless data acquisition system design which is based on wireless sensor networks. Using ZigBee short-range wireless communications technology for data transmission, so that the system will not only significantly reduces the amount of equipment, but also makes the system placed flexibly and moves easily. As the whole system-wide monitoring center, FPGA is responsible for getting the data together which is gathered from various nodes in the system and it also controls over the whole system intelligently. The results proved that the system is used simply, and works stably, reliably, fast and efficiently; whats more, it has a broad application prospect.
