Abstract
Description
Technical Field
[0001] The invention relates to the field of early warning monitoring equipment, and in particular to an integrated device for protecting schools in hilly areas. Background Art
[0002] The landslide early warning monitoring system is a technical system for monitoring and warning landslide disasters. The system integrates a variety of sensors, data acquisition equipment, data transmission networks, and data analysis and early warning platforms to achieve real-time monitoring, data analysis, and early warning of landslide risks. The landslide early warning monitoring system uses various sensors to monitor the mountain in all directions. These sensors include displacement sensors that measure surface displacement, liquid level sensors that monitor groundwater levels, and rain gauges that record rainfall. By sensing key parameters such as the displacement, tilt, groundwater changes, and rainfall of the mountain in real time, the system can obtain precursor information of landslides. The monitored data is transmitted to the data processing center in real time through the data transmission network. This process relies on advanced communication technologies such as 4G / 5G, LoRa, Beidou satellite communications, etc. to ensure accurate and fast data transmission. At the data processing center, the system will conduct in-depth analysis and processing of the received data to identify potential landslide risks. Once the data analysis results show that there is a risk of landslide, the early warning system will immediately start the early warning process. Early warning information can be released to relevant departments and the public through a variety of means, such as text messages, telephone calls, broadcasts, online platforms, etc. At the same time, the system can also formulate targeted emergency response measures according to the risk level and regional characteristics to minimize the losses caused by landslides.
[0003] However, the existing technology is expensive and requires a large investment. In addition, the existing early warning devices cannot provide a gradient integrated alarm according to the occurrence and progress of landslides. The general early warning system only has landslide alarms, and there are no flash flood or rainstorm warnings. General landslide alarm devices are mostly infrared or laser monitoring, which is not cheap. Without government investment, schools in hilly areas will not purchase and install them themselves. This alarm device is low-cost and highly economical and practical. Therefore, the purpose of this early warning device is to be installed in schools in hilly areas that are closest to mountains, slopes, rivers, and low-lying areas, so as to achieve low-cost and low-tech security for schools and their surroundings, and it has great prospects for development and promotion.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.
[0021] The present invention is described in further detail below by way of examples.
[0022] In hilly areas, campus safety faces severe challenges from geological disasters such as landslides and flash floods. In response to this situation, the School Guardian was developed, an integrated device to protect schools in hilly areas. The device is committed to providing comprehensive and effective disaster warning and protection for campuses in hilly areas, ensuring the safety of teachers and students and the stability of the campus. Example
[0023] like Figure 1 , an integrated device for protecting schools in hilly areas, including a power supply, a main control unit connected to the power supply, a rainfall monitoring system, a mountain flood water level monitoring system, and a crack widening monitoring system respectively connected to the input end of the main control unit; and an alarm system and a display system respectively connected to the output end of the main control unit; the rainfall monitoring system transmits the rainfall information to the display system through the main control unit, and displays it in real time through the display system. When the water value reaches the threshold set by the main control unit, the main control unit controls the alarm system to alarm; the mountain flood water level monitoring system transmits the water level information to the display system through the main control unit, and displays it in real time through the display system. When the water level value reaches the threshold set by the main control unit, the main control unit controls the alarm system to alarm; the crack widening monitoring system transmits the crack value information to the display system through the main control unit, and displays it in real time through the display system. When the crack value reaches the threshold set by the main control unit, the main control unit controls the alarm system to alarm.
[0024] In this embodiment, the main control unit is an Arduino NANO main control board. The core of the device is a high-performance Arduino NANO main control board, which acts as a data processing center. After receiving data from various sensors, the main control board quickly runs a preset algorithm to analyze the data.
[0025] In this embodiment, the display system uses an OLED display screen, which displays key environmental information such as rainfall, water level, and mountain crack values in the form of intuitive charts and data, making it convenient for teachers and students to view at any time.
[0026] In this embodiment, the alarm system uses an audible and visual alarm device. When the disaster risk reaches a certain threshold, a voice alarm is first issued through a built-in speaker to remind teachers and students of the type of disaster that may occur. At the same time, a warning light installed in a conspicuous position on campus begins to flash to attract the attention of teachers and students.
[0027] In this embodiment, the rainfall monitoring system uses a raindrop sensor. The rainfall monitoring system uses a raindrop sensor to display rainfall information in real time through an OLED display screen. When the water volume reaches a certain value, it automatically broadcasts excessive rainfall information and an audible and visual alarm device reminds.
[0028] In this embodiment, the mountain flood water level monitoring system uses a water level sensor. The mountain flood water level monitoring system uses a water level sensor, which can display water level information in real time through an OLED display screen. When it reaches a certain value, it automatically broadcasts high water level information and there will be an audible and visual alarm device to remind.
[0029] In this embodiment, the crack widening monitoring system uses a crack monitoring device. The crack widening monitoring system uses a crack monitoring device, which can display crack value information in real time through an OLED display screen. When the crack value reaches a certain value, it automatically broadcasts information that the crack value is too large and there will be an audible and visual alarm device to remind.
[0030] In this embodiment, the crack widening monitoring system specifically makes two fixed points at both ends of the mudstone crack, installs an elastic switch on the fixed point of the mountain on the upper side of the crack, and then connects the switch to the fixed point on the lower side of the crack with a wire. When the crack increases to a certain extent, the tension of the wire increases, causing the switch to close, causing the alarm system to sound an alarm.
[0031] The rainfall monitoring system The understanding that landslides are caused by long-term soaking in rainwater: Since the most important factor inducing landslides is rainwater, there must be a rainfall alarm device. When the rainfall reaches a certain preset value, an alarm will be issued to remind people to strengthen vigilance and precautions, especially at night. When the rainfall level reaches a certain set value, the raindrop sensor energizes the circuit and emits a rapid sound and flash alarm. After many experiments, the device is very sensitive and can be triggered at any time after the threshold is adjusted.
[0032] The mountain flood level monitoring system The water level sensor checks the rising water level. The device can promptly detect when the water level exceeds the limit and sound an alarm. The water level information on the display screen is updated in real time.
[0033] The crack widening monitoring system Since the basic potential points of landslides have been identified, the most important thing is to know the extent of the existing cracks. Before a landslide forms, the cracks will certainly widen a lot. So two fixed points are made at both ends of the mudstone cracks, and an elastic switch is installed on the fixed point of the mountain on the upper side of the crack. Then the switch is connected to the fixed point on the lower side of the crack with a wire. When the cracks increase to a certain extent, the tension of the wire increases, causing the switch to close, and the alarm system to sound an alarm. The obvious increase in cracks is a direct precursor to a landslide, and emergency evacuation is necessary. If a school landslide occurs at night, teachers and students must be notified to evacuate.
[0034] Disaster Monitoring Principles Based on the in-depth study of the formation mechanism of common geological disasters in hilly areas, the device integrates a variety of high-precision sensors. For example, for the flash flood level monitoring system, water level sensors are installed in rivers and drainage channels near the campus. The water level sensors can keenly sense water level changes. At the same time, combined with the data of rainfall sensors, the possibility of flash floods is comprehensively analyzed.
[0035] Main control and data processing The core of the device is the high-performance Arduino NANO main control board, which acts as the data processing center. After receiving data from various sensors, the main control board quickly runs the preset algorithm for data analysis.
[0036] Taking landslide monitoring as an example, the main control board calculates the risk factor of landslides through complex mathematical models based on the data from various sensors. For flash flood warning, the probability of flash floods is determined by combining water level and rainfall data.
[0037] Alarm and display system The device is equipped with alarm devices, including sound and light alarms. When the disaster risk reaches a certain threshold, a voice alarm is first issued through the built-in speaker to remind teachers and students of the type of disaster that may occur. At the same time, the warning light installed in a conspicuous position on campus begins to flash, attracting the attention of teachers and students.
[0038] In order to allow teachers and students to intuitively understand the real-time conditions of the campus environment, the device also includes an OLED display screen. The display screen displays key environmental information such as rainfall, water level, and mountain crack values in the form of intuitive charts and data, which is convenient for teachers and students to view at any time.
[0039] The present invention accurately monitors disaster risks: it solves the problem of incomplete and untimely monitoring of disaster risks such as landslides, mud-rock flows, and floods in complex terrain and environments around schools in hilly areas in the prior art. By reasonably arranging sensors, such as setting corresponding sensors at key locations such as teaching buildings and dormitories on the mountain side, low-lying areas on campus, near the school drainage system, areas adjacent to mountains around the campus, near rivers and streams, roads that must be taken to go to and from school, and around campus walls, it can achieve accurate monitoring of various disaster risk factors such as mountain displacement, loosening of rock and soil, changes in water level, rainfall, and mountain cracks.
[0040] The present invention overcomes the shortcomings of traditional manual inspections that are difficult to monitor in real time and the poor adaptability of some monitoring equipment in special terrain and high-density school scenarios, ensuring that potential disaster risks can be discovered in a timely manner.
[0041] The present invention provides timely and efficient warning: it changes the situation that the existing warning methods are delayed and the information is not transmitted in time, and adopts multiple warning methods such as sound and light alarm, campus broadcast, alarm prompt, display screen prompt, etc., combined with the environmental monitoring sensing warning part, alarm and information display part and auxiliary function part (such as light display, voice prompt, etc.) of the intelligent alarm device, to issue an alarm to teachers and students as soon as possible before the disaster occurs, so as to buy precious escape time for teachers and students.
[0042] The present invention solves the problems of slow manual response and untimely evacuation in the face of sudden disasters in the prior art. By optimizing the early warning system, such as presetting a rainfall threshold, and using raindrop sensors and water level sensors to monitor rainfall and water level changes in real time, an alarm is immediately triggered when the threshold is reached, thereby ensuring the timeliness and accuracy of the early warning.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
