A sensor to a sensor networking available 1channel stand alone wireless data logger

摘要

The present invention relates to a stand-alone small data collection device based on wireless communication, the configuration of which receives a measurement information signal from a plurality of measurement sensors, and transmits an information signal having a function of transmitting the received measurement information signal At least one medium is formed, and the medium and the medium are formed to be spaced apart from each other by a predetermined distance such that the wireless communication unit for transmitting the measurement information signals transmitted from the plurality of measurement sensors through the medium; Receiving the measurement information signal periodically sent by the wireless communication unit, and stores the received measurement information, and transmits the measurement information to an analyzer such as a computer for analyzing and interpreting the stored measurement information,;A reception antenna for efficiently receiving the measurement information signal transmitted from the wireless communication unit, an A / D converter for converting the measurement information signal efficiently received through the reception antenna into digital data, and the conversion in the A / D converter An information storage unit for collecting and storing the measured measurement information for a predetermined time, a USB (Universal Serial Bus) terminal for transmitting the measurement information stored in the information storage unit to the analyzer, and the A / D converter and the information storage unit. And a data collecting device comprising a power supply unit for supplying power and an on-off switch for determining a power supply of the power supply unit.;Since the data communication device and the plurality of measurement sensors are interconnected based on the wireless communication due to the wireless communication unit, it is easy to install and there is no limit of the separation distance between the measurement sensor and the data collection device due to the wireless communication unit. Even if the sensor is installed in a structure installed on a high mountain, the data collection device can be installed under a mountain that can be easily recovered and installed, thereby providing a user with convenience of recovery and installation.;In addition, the data communication device and the plurality of measurement sensors are connected to each other based on the wireless communication due to the wireless communication unit, thereby preventing the problems caused by the wires in advance, thereby analyzing and analyzing the measurement information through the analyzer. There is an effect that can increase the reliability.;In addition, since the time sensor and the temperature measurement sensor is built in the data collection device, in addition to the measurement information transmitted from two to three measurement sensors further includes measurement information transmitted from the time sensor and the temperature measurement sensor embedded in the data collection device. By analyzing and interpreting the information, the reliability of the result through the analyzer can be further increased.;Data acquisition device, wireless communication, Zigbee, Bluetooth, abnormal displacement measurement
