This is a system for real-time monitoring of tidal levels by wirelessly transmitting tidal data measured at a measurement station to confirmation locations such as workboats and offices using a wireless modem. A measurement box and a transmitting wireless modem are installed at the measurement location, and power is supplied. At the location where data needs to be checked, a computer and a receiving wireless modem are set up, and once configured, measurements can be taken. Depending on the required variation and accuracy, you can choose the optimal configuration from a basic setup consisting of four types of sensors.

Automatically measure the dust concentration at multiple measurement locations and centrally manage the measurement results. Install dust meters at the locations where measurements are to be taken, transmit the measurement data to the management location, and import the data into a computer. On the computer side, the data transmitted from the dust meters is processed and displayed and recorded as individual measurement values. If a measurement value exceeds the pre-set allowable limit, an alarm system can be activated. Measurement records are taken at pre-set time intervals, and the measurement results are recorded on the hard disk. Dust meters can be selected according to the intended use. Additionally, other devices such as anemometers and thermometers can also be connected.

Traditionally, it was difficult to measure weather data in locations without power facilities, but it has become possible to observe this data by combining batteries and solar panels for power supply. The observation data is collected nationwide by utilizing NTT Docomo's FOMA communication network. If there is an internet-accessible environment, real-time evaluation of the observation data can be done using a computer or mobile phone. Weather data can simultaneously observe six parameters: wind direction, wind speed, precipitation, atmospheric pressure, temperature, and humidity.

This is a system that automatically measures the displacement of structures such as slopes and bridge piers. Reflective prisms are installed at points where displacement measurement is desired, and measurements of the reflective prisms are sequentially taken from a total station set up at a fixed point, calculating the displacement amount for each point. On the computer side, automatic measurement is performed through command control of the total station, along with calculations of coordinate values and displacement amounts, as well as data recording. If a displacement exceeding the pre-set allowable value is measured, an alarm device can be activated.
