The system architecture of real-time bridge health monitoring and alert system using IoT mentioned below.
Let’s understand the details of the used components of the system architecture.
Sensors: Here, we have used the sensors like weight sensor and water level point sensor. These sensors are responsible for sensing the load on the bridge, and the level of water in the river. The output will be in the electrical signal.
Arduino Uno: The Arduino Uno is a microcontroller board based on the ATmega328P. There are 14 digital input/output pins, 6 analog inputs, a 16 MHZ quartz crystal, a USB connection, a power jack, and an ICSP header with a reset pin.
Wi-Fi Module ESP8266: The ESP8266 is a low-cost WI-FI chip, with a full TCP/IP and microcontroller capability.
Features of ESP8266:
- Processor: L106 32-bit RISC microprocessor
- Memory: 32 KiB Instruction RAM
- 32 KiB Instruction cache RAM
- 80 KiB user-data RAM
- 16 GPIO Pins
Let’s see how the system architecture works:
The system architecture model consists of an Arduino microcontroller board, sensors, and ESP8266 Wi-Fi module.
ESP8266 is used as an embedded device for sensing and storing the data. Arduino board consists of 12 analog inputs pins and 14 digital I/O pins. Wi-Fi module used to connect the embedded device to the internet. Sensors are connected to the Arduino board. It reads the sensor’s data. Using these sensor values, the corresponding environmental parameters are evaluated. The embedded system has been designed for environmental monitoring. The load sensor detects the load on the bridge. The water level point sensor detects the water level. If the threshold limit is crossed, the corresponding controlling action is initiated such as barrier gets fall and buzzer sounds. The embedded system is connected to the internet through the Wi-Fi module. After sensing the data from different sensor devices, the sensed data automatically send to the authority or admin on their mobile app.
The government spends huge money to build bridges and roads. There are challenges to take care of bridges. Using new technology, there is the possibility to get an advance alert notification before a dangerous situation arises. Using IoT based real-time bridge health monitoring system, the authority can easily get a prior alert message. This system can save the lives of people as well as easily get notification of environmental parameter changes.
The continuously real-time bridge health monitoring system helps to get an alert notification. With the help of a buzzer and auto-barrier. If a load of vehicles and level of water in the river crosses its threshold values, the alert system will be activated.
