In the event of an emergency, including through communication, the situation is provided in advance.
The communication module 120d of G-Block initializes the value of monitoring information, which is various data, after the field installation of G-BLOCK and provides the tilted later state through short-distance wireless communication with the IoT gateway 200. It is provided to the monitoring server 400, the driver terminal 500, and the manager terminal 500a through the connected network 300,
For the purpose of early warning and advance warning from various disasters, G-Block prevents accidents by notifying all vehicle drivers of the road ahead situation through SMS, alarm, or electronic signage.
Based on the retaining wall block 100, by using a smartphone possessed by a dedicated driver equipped with a GPS receiver, a computing function of a smart pad and a driver terminal 500 equipped with a GPS receiver to provide navigation guidance to the driver or When the guidance on the retaining wall block is performed through the location search of the jibloc itself, the monitoring server 400 provides a location guidance service through rain information,
When the humidity inside the G-block is higher than the preset humidity in the rainy state by the humidity sensor provided in the sensor module 120b provided in the G-block, the monitoring server 400 provides rain information through the IoT gateway 200 in the G-block. In accordance with the provision, it receives and stores rain information and identification ID (ie, location information) of G-block from the IoT gateway 200 through the network 300,
The monitoring server 400 performs navigation guidance or when rain information is detected within a preset distance of a route when guidance for a sidewalk block is performed through a location search of G-block itself, By calculating the distance information to the location information and transmitting it to the driver terminal 500, the rain information is output together with the distance information through the speaker, which is each audio output unit, so that guidance to the driver for localized heavy rain is performed, It provides not only rain information but also snowfall information, and when a temperature sensor is included in the sensor module 120b, it prevents the driver from entering the G-block corresponding to the location where the heat wave information occurred, thereby preventing the driver from entering the G-block due to various disasters. Notifies the earthquake and the situation related to the cut-off road,
Two G-blocks are formed on both sides with the LED element as the center on the upper surface of the solar module 120a formed in the upper center of the body,
The LED element is a multi-color LED in which R, G, and B elements are bundled into one package. , color and brightness can be realized by using PWM (Pulse Width Modulation) method as well as color combination.
When the MPU (120u) is stored in the battery (120c) formed as a capacitor after the solar energy is converted into electric power energy by the photovoltaic module (120a), using the power stored in the battery (120c) to control the lighting on the LED element and , to the manager terminal 500a possessed by the operator through the beacon transmission/reception terminal of the communication module 120d, and performs a function of transmitting the location information of the G-block to be worked through the beacon signal of LoRa communication,
The manager terminal 500a that has received the beacon signal periodically checks the detection of the direction change of the beacon signal through the NFC detector formed in the manager terminal 500a, and when the direction change of the beacon signal is detected, the recognition signal through vibration or voice signal By outputting , the operator can safely recognize the direction to the
MPU (120u) not only performs control of the amount of power of the beacon transmitting and receiving terminal so as to be adjusted between 2 to 3m with respect to the receiving range of the beacon signal including the G-block location information, but also for the NFC detector formed in the manager terminal (500a) By checking the RTT (Round Trip Time) for the beacon signal, the RTT measurement value of the current own retaining wall block 100 increases, and the RTT measurement value by the MPU 120u of another neighboring support block decreases, RTT When the G-Block location information for which the measured value is reduced is in the direction adjacent to the G-Block corresponding to the work location initially provided to the manager terminal 500a, the manager terminal to the monitoring server 400 through the network 300 connected to the IoT gateway 200 Transmits control information to maintain the current direction to (500a), on the contrary, when the RTT measurement value of the current own subblock increases, and the RTT measurement value by the MPU 120u of another neighboring subblock decreases, RTT If the G-Block location information for which the measured value decreases is in a direction not adjacent to the G-Block corresponding to the work location initially provided to the manager terminal 500a, the IoT gateway 200 is connected to the monitoring server 400 through the network 300. Transmitting control information corresponding to the direction information changed from the current direction to the manager terminal 500a,
Through the transmitted information, information on the stability of the worker's night work is provided for each zone at night through the LED element. When the RTT measurement by the MPU 120u decreases, it generates speed information proportional to the increase and decrease, blue (or green) in the first speed section of the first step, and in the second speed section of the second step In the third speed section of the third step (the speed increases as the first, second, and third speed) of the third step, the LED element of the retaining wall block 100 approaches with a different color, such as red (flashing possible). Concrete retaining wall block operation management system for disaster prevention, characterized in that it also displays information about the movement speed of the worker through blinking.
