The present invention relates to a multiplexer, and more particularly, to a multiplexer having a data logger function incorporating a function of a data logger in a multiplexer to collect and relay measurement data transmitted from a measurement sensor installed in various construction sites. It is.

Recently, due to the construction of new towns and the development of industry, construction of various structures such as bridges, tunnels, high-speed railways, and high-rise buildings has been actively conducted. To this end, various systems have been introduced.

In general, the measurement management of these various construction sites are largely used in the manual measurement method and the automatic measurement method.

First, the manual measurement method installs the measuring equipment on the structures where various abnormalities of construction sites such as bridges, tunnels, high-speed railways and high-rise buildings are expected, and the site manager frequently checks the measured data from the measuring equipment through manual measuring equipment. After the measurement, the measured data is input to the office computer and the database is processed to determine the abnormality of various structures.

In addition, as shown in Figure 1, the automatic measurement method is installed in various structures, the measurement sensor 10 for measuring the abnormal displacement of the structure, and a multiplexer for converting the analog signal measured from the measurement sensor 10 into a digital signal 20, a data logger 30 for collecting and relaying measurement data transmitted from the multiplexer 20, a transceiver 40 for transmitting and receiving measurement data collected and relayed from the data logger 30, and a transceiver It consists of an operating computer (50) for processing and analyzing the measurement data transmitted from the (40) is a way to determine the abnormality of the various structures.

However, in the case of the manual measurement method, since the manager measures the measurement equipment through the manual measurement equipment, it takes a lot of time on the site measurement, making it difficult to quickly manage the site measurement. There is a problem.

In addition, in the case of the automatic measurement method, since the multiplexer and the data logger are separated from each other, the system related to the measurement management of the construction site is complicated, and the maintenance cost of the system is high. There is a problem that is difficult to upgrade.

The present invention has been made to solve the above problems, the purpose of which is a complex type having a data logger function incorporating the function of the data logger in the multiplexer to collect and relay the measurement data transmitted from the measurement sensor of various construction sites To provide a multiplexer.

The hybrid multiplexer having a data logger function of the present invention for achieving the above object is an analog board 210 for converting analog signals measured from a plurality of measurement sensors into digital signals, and transmitted from the analog board 21. And a main board 220 for collecting and relaying the measured data, and a power supply 230 for supplying power to the analog board 210 and the main board 220.

Here, the analog board 210 includes a filter 211 for filtering data measured by a plurality of measurement sensors, and an A / D converter 212 for converting an analog signal transmitted from the filter 211 into a digital signal. It is preferable that it consists of.

In addition, the main board 220 and the storage unit 221 for collecting and storing the measurement data transmitted from the analog board 210, the control unit 222 for controlling the measurement data stored in the storage unit 221 and Preferably, the controller 222 is configured to transmit and receive the measurement data controlled by the controller 222 to the outside.

In addition, the power supply 230 may be any one of a battery, an AC power source and a solar cell.

In addition, the transceiver 223 is preferably wired communication and wireless communication is applicable.

Hereinafter, a hybrid multiplexer having a data logger function according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
