摘要
随着城市交通的不断发展，道路积水问题对交通通行安全和效率的影响愈发显著。传统的道路涉水管理多依赖人工巡查和经验判断，不仅预警滞后，而且难以精准掌握积水深度，给车辆和行人安全带来隐患，难以满足现代化城市交通管理的需求。
基于 STM32F103C8T6 单片机的城市道路涉水线报警控制系统，整合了 YW-J 水位监测模块、OLED 显示模块、按键、WiFi 模块 ESP8266 及黄、红、绿警示灯等，实现了道路积水的自动化监测与分级报警。系统核心功能包括：通过 YW-J 实时监测道路水位，水位处于安全范围时亮绿灯，1 级警戒时亮黄灯，2 级警戒时亮红灯；支持通过按键设置两级水位阈值；通过 OLED 显示模块展示水位，超过 1 级水位时显示 “1 级 (当前积水 xx 米，谨慎行驶)”，超过 2 级水位时显示 “2 级 (当前积水 xx 米，禁止行驶)”；利用 WiFi 模块 ESP8266 将警戒数据发送到手机端，显示为 “(a 道路低洼处涉水深度 xx 米)”，且手机端可设置水位阈值。
该系统的实现，有效提升了城市道路涉水监测的自动化与精准化水平，减少了人工干预，为交通参与者提供了及时的警示信息，保障了道路通行安全，同时为同类道路积水监测系统的研发提供了参考，具有较高的实际应用价值。

ABSTRACT
With the continuous development of urban transportation, the impact of road waterlogging on traffic safety and efficiency has become increasingly significant. Traditional road waterlogging management mostly relies on manual inspection and empirical judgment, which not only results in delayed early warning but also makes it difficult to accurately grasp the depth of waterlogging, posing hidden dangers to the safety of vehicles and pedestrians, and thus failing to meet the needs of modern urban traffic management.
The urban road water level alarm control system based on the STM32F103C8T6 microcontroller integrates the YW-J water level monitoring module, OLED display module, buttons, ESP8266 WiFi module, and yellow, red, and green warning lights, realizing automatic monitoring and graded alarm of road waterlogging. The core functions of the system include: real-time monitoring of road water level through YW-J, with a green light on when the water level is within the safe range, a yellow light on for level 1 alert, and a red light on for level 2 alert; supporting the setting of two-level water level thresholds through buttons; displaying the water level through the OLED display module, showing “Level 1 (current water accumulation xx meters, drive with caution)” when exceeding the level 1 water level, and “Level 2 (current water accumulation xx meters, no entry)” when exceeding the level 2 water level; using the ESP8266 WiFi module to send warning data to the mobile phone, which displays “(The water depth at the low-lying part of Road A is xx meters)”, and the mobile phone can set the water level thresholds.
The implementation of this system has effectively improved the automation and precision level of urban road waterlogging monitoring, reduced manual intervention, provided timely warning information for traffic participants, ensured road traffic safety, and provided a reference for the research and development of similar road waterlogging monitoring systems, with high practical application value.
