【摘要】：隨著私家車數(shù)量逐年劇增,為減緩交通壓力,各大城市陸續(xù)建立了數(shù)量巨大的涵洞、立交橋等。而暴雨天氣下會導(dǎo)致排水系統(tǒng)癱瘓,使涵洞、下穿隧道等道路低洼處的大量積水無法及時排出,給人們的生命和財產(chǎn)帶來極大的威脅,因此建立完善的涵洞積水自動監(jiān)測系統(tǒng)已迫在眉睫。本課題是針對人們誤入涵洞、下穿隧道等道路低洼處大量積水的現(xiàn)象,設(shè)計并實現(xiàn)了一款基于STM32F103的涵洞積水自動監(jiān)測系統(tǒng)。本系統(tǒng)由下位機監(jiān)測終端設(shè)備和上位機監(jiān)測中心組成。系統(tǒng)下位機首先通過超聲波傳感器對積水的水位信息進行實時采集,然后在監(jiān)測站點利用LCD顯示屏實時顯示積水信息并給予相應(yīng)的警示;根據(jù)擋車器的工作原理,本系統(tǒng)采用控制步進電機角位移的方法,實現(xiàn)擋車器的起落功能;采用GPRS無線通信模塊把各個監(jiān)測終端設(shè)備采集的積水水位信息發(fā)送到監(jiān)測控制中心,同時還將采集的水位數(shù)據(jù)信息采用短信的方式經(jīng)過GSM網(wǎng)絡(luò)發(fā)送給負責處理積水的相關(guān)人員。上位機監(jiān)控中心接收到GPRS傳輸?shù)臄?shù)據(jù)后,數(shù)據(jù)以數(shù)字和曲線形式呈現(xiàn)在C#設(shè)計的人機交互界面上,最后將接收到的數(shù)據(jù)存儲到SQL數(shù)據(jù)庫,以備將來之所需。監(jiān)測控制中心也可通過廣播、電臺、電視、網(wǎng)站等發(fā)布涵洞積水的水位信息。系統(tǒng)經(jīng)過整體模擬測試后,人機交互界面能夠準確的顯示數(shù)據(jù),系統(tǒng)具有較低的誤碼率、較強的穩(wěn)定等特點;步進電機能根據(jù)水位高度自動工作,大大降低了系統(tǒng)的成本。除此之外,系統(tǒng)可以有效提醒人們有關(guān)涵洞積水的信息,防止人們誤入積水較深的涵洞或道路低洼處。為人們的安全出行,提供了保障。
[Abstract]:With the number of private cars increasing sharply year by year, in order to reduce traffic pressure, a large number of culverts and overpasses have been built in cities. Rainstorm weather will lead to a breakdown of the drainage system, causing a large amount of stagnant water in low-lying places, such as culverts and tunnels, to be discharged in a timely manner, posing a great threat to people's lives and property. Therefore, it is urgent to establish a perfect automatic monitoring system for culvert water accumulation. This paper aims at the phenomenon that people stumble into culvert and tunnel, and design and implement an automatic monitoring system of culvert water accumulation based on STM32F103. The system consists of the monitoring terminal equipment of the lower computer and the monitoring center of the upper computer. The system's lower computer firstly collects the water level information by ultrasonic sensor, and then displays the water level information with LCD display screen in the monitoring station and gives the corresponding warning; according to the working principle of the car stopper, the system uses the monitoring station to display the water level information in real time and give the corresponding warning. The system adopts the method of controlling the angular displacement of stepping motor to realize the hoisting and landing function of the stopper, and transmits the water level information collected by the monitoring terminal equipment to the monitoring control center by using the GPRS wireless communication module. At the same time, the collected water level information is sent by SMS via GSM network to the relevant personnel in charge of dealing with the water. After receiving the data transmitted by GPRS, the host computer monitoring center presents the data in digital and curvilinear form on the human-computer interface designed by C #. Finally, the received data is stored in the SQL database for future use. Monitoring and control center can also broadcast, radio, television, website and other information about the water level of culverts. After the whole simulation test, the man-machine interface can display the data accurately, the system has the characteristics of low bit error rate, strong stability and so on. The stepper motor can work automatically according to the water level, which greatly reduces the cost of the system. In addition, the system can effectively alert people to information about culverts and prevent people from straying into deeper culverts or low-lying roads. For the safety of people travel, provide protection.
