Project Development Overview
In this project, we collaborated with a well-known smart traffic data survey company to develop the "Smart Mountain Road Safety Warning Device" product, with YenProtek providing various underlying technological supports. The products are primarily planned to be installed on major tourist routes such as Highway 166 (Meishan) and Highway 129 (Longmei) in Chiayi. Due to poor local road conditions, featuring numerous sharp curves, intersections, and steep slopes, many road sections only allow single-vehicle passage. Especially during holidays with heavy traffic, drivers often make poor decisions due to a lack of sufficient information about upcoming traffic conditions, leading to traffic accidents. Furthermore, establishing road safety monitoring systems in remote areas is often difficult due to terrain constraints. Wiring is inconvenient and construction difficulty is high, which is usually accompanied by enormous installation and maintenance costs. These difficulties are also one of the main challenges this project hopes to overcome.
Based on the client's needs, we developed the "Smart Mountain Road Safety Warning Device" for remote outdoor areas, mountains, and roads under special conditions. The goal is to emit real-time and clear flashing LED warning signals to indicate that vehicles from the opposite side or intersection are entering a curve or narrow road, reminding road users to watch out for oncoming traffic. This helps avoid entering narrow curves simultaneously, thus reducing accidents and traffic jams caused by forced passing on narrow curves. Considering the need for outdoor wireless applications, a waterproof design is used to withstand the frequently changing outdoor mountain environments. At the same time, to adapt to the remote mountain terrain, the power supply utilizes environmental green energy (solar or wind power), eliminating the need to consider the costs of additional mains electricity installation and cumbersome construction processes. Installation is not limited by terrain and location, making it safer, easier to install, and more cost-effective, while significantly enhancing the system's adaptability.
In addition to real-time warning functions, the system simultaneously uploads collected vehicle data and warning information to the Cloud. This helps traffic control authorities manage and maintain the systems for each installed road more effectively, improving traffic management efficiency and reducing system maintenance costs, creating safe and smart intersections for a secure travel environment.
Currently, the Smart Mountain Safety Warning System project has been practically deployed in multiple locations in the Chiayi mountain area and has shown excellent installation results. The Chiayi County Government also plans to expand installation areas further to improve driving safety for mountain residents and tourists.
Project Development Information
Implementation Methods and Structural Design:
The system is planned to install vehicle detection sensors on the roadside before entering curves or intersections. The vehicle sensor uses calculation logic to identify the passing vehicle type (filtering out motorcycles, bicycles, and pedestrians) and determines the vehicle's driving direction. When a vehicle passes the intersection or enters a blind curve, the system triggers a warning light at the other end of the road where a warning is needed, alerting road users to watch out for oncoming traffic. While issuing warnings, relevant data is uploaded to the Cloud system via the network, allowing relevant authorities to monitor it remotely and directly.
The "Smart Mountain Safety Warning System" consists of at least two sets of vehicle detection sensors and a Cloud system. The vehicle detection sensors mainly include: infrared sensor modules, LED warning lights, power supplies, and control systems. Since they are mostly installed and used in outdoor environments, we strive to ensure convenient and rapid installation and disassembly in planning and design, helping owners reduce installation difficulties and subsequent maintenance costs. We primarily chose stainless steel as the main material to provide sufficient strength and better weather resistance.
- 2 sets of infrared sensors are used to determine the vehicle type and driving direction when a vehicle passes.
- Uses single-beam infrared sensors with an effective range of 15m, which can cover the width of general mountain roads.
- Infrared transmitters and receiver modules are installed on each side of the road. The detection application requires the transmitter to face the receiver. The transmitter sends an infrared beam to the receiver. When a vehicle passes, the beam is interrupted, and the system can identify that a vehicle has passed. Two sets of infrared sensors at the same intersection, spaced 1 meter apart, can effectively determine the vehicle's type and direction of travel.
- LED warning lights and warning signs are locked onto steel pipes and installed on the side of the road. Their main function is to warn oncoming vehicles.
- Uses a stainless steel box that can house the battery inside and secure the solar power management module simultaneously. Side holes are provided for convenient wiring. The box is designed with a rear hook to facilitate attachment to steel pipes, promoting rapid construction.
- Uses a solar power system to supply power to the infrared sensor transmitter and warning light.
- Solar power module: A 60W solar panel and power management module are used to power the system. A 55AH battery can be fully charged within 1~2 sunny days. Once fully charged, it can operate for 7-10 days during rainy periods without solar charging.
- Uses a stainless steel box with side holes for convenient wiring. The rear hook design easily attaches to steel pipes, enabling rapid deployment.
- The solar power system supplies power to the system, utilizing a control module to manage vehicle detection and warning lights, and can connect to the network to upload relevant data to the Cloud system.
- Circuit control board: One control module processes sensor inputs and warning light outputs, while the other processes data and uploads it to the Cloud via NB-IoT. The input terminal uses optocouplers for analog sensor data input, and the output terminal uses a relay module to control the warning lights. It also includes an ADC set to detect voltage and monitor battery power.
- Stores uploaded detection data and can be used for remote settings and monitoring. The transmitted data is logged on the Cloud platform. Relevant upload data can be queried based on different conditions. Meanwhile, the data can be sorted and downloaded as EXCEL forms for analysis and utilization.
