Description

Technical Field

[0001] This utility model relates to the field of environmental monitoring technology, and in particular to an intelligent monitoring system for septic tanks based on sensor data. Background Technology

[0002] With the accelerating pace of urbanization, the use of septic tanks in residential areas, factories, schools, and other locations is becoming increasingly widespread. As an important wastewater pretreatment facility, the operational status of septic tanks directly affects environmental sanitation and public safety. However, traditional septic tank management methods mainly rely on regular manual inspections and experience-based judgment, which is not only inefficient but also poses significant safety hazards. In the event of abnormal conditions such as excessively high liquid levels or excessive gas concentrations, delays in detection often lead to septic tank overflows, explosions, or toxic gas leaks, resulting in serious consequences.

[0003] In recent years, although some regions have attempted to introduce sensor devices into septic tanks for basic monitoring, the low system integration, limited sensor data, and lack of data processing capabilities still fail to meet the needs for comprehensive, accurate, and real-time monitoring of septic tank conditions. Furthermore, most existing systems lack remote communication capabilities, preventing timely feedback of monitoring data to management personnel and hindering prompt responses to anomalies.

[0004] In view of this, the inventor has designed a smart monitoring system for septic tanks based on sensor data, which leads to this invention. Utility Model Content

[0005] (a) Technical problems to be solved The purpose of this application is to provide an intelligent monitoring system for septic tanks based on sensor data, which at least solves the problems of existing septic tank monitoring systems, such as limited monitoring methods, inability to perceive multiple key parameters in real time, lack of remote early warning capabilities, and consequently, difficulty in timely detection and handling of safety hazards.

[0006] (II) Technical Solution To solve the above-mentioned technical problems, this utility model provides the following technical solution: This application provides a septic tank intelligent monitoring system based on sensor data, characterized in that it includes a septic tank body, sensor modules installed at different positions on the septic tank body, a data acquisition unit connected to the sensor modules, a main control processing unit connected to the data acquisition unit, a wireless communication module communicatively connected to the main control processing unit, a terminal device for receiving remote monitoring information, and a power supply device for providing power to the system. The sensing module includes a gas sensor, a liquid level sensor, and a temperature and humidity sensor, which are used to collect data on the concentration of harmful gases, the liquid level, and the ambient temperature and humidity in the septic tank, respectively. The main control processing unit is used to analyze the various sensor data transmitted by the data acquisition unit, and send alarm information to the terminal device through the wireless communication module when an abnormal state is detected. The power supply device includes solar panels and a battery; The system is housed in an integrated housing.

[0007] In a further embodiment, the wireless communication module is an NB-IoT communication module or a LoRa communication module.

[0008] In a further embodiment, the terminal device includes a mobile terminal or a remote management platform server with a monitoring client installed.

[0009] In a further embodiment, the monitoring client has a graphical interface for displaying the sensor parameters and alarm status inside the septic tank in real time.

[0010] In a further embodiment, the gas sensor is a multi-component gas sensor for detecting biogas and hydrogen sulfide.

[0011] In a further embodiment, the main control processing unit is equipped with an alarm threshold module, which generates an alarm signal when any sensing parameter exceeds a set threshold.

[0012] In a further embodiment, the alarm signal includes audible and visual alarm signals and remote push notifications.

[0013] In a further embodiment, the power supply device further includes a power monitoring unit for detecting the remaining power of the battery and feeding it back to the main control processing unit.

[0014] In a further embodiment, an automatic venting valve is also included, installed on the top of the septic tank body, for automatically discharging some harmful gases under the control of the main control processing unit.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention has the following advantages: By integrating gas sensors, liquid level sensors, and temperature and humidity sensors, the system achieves comprehensive monitoring of key parameters inside the septic tank. The main control processing unit intelligently analyzes the collected data and transmits alarm information to a remote terminal in real time via a wireless communication module, thereby significantly improving the septic tank's operational status perception and remote management efficiency. At the same time, the system adopts solar power supply and an integrated protective shell structure, possessing good self-sufficiency and environmental adaptability. This solves the problems of low efficiency, untimely response, and unstable equipment operation in harsh environments associated with traditional manual inspections, thus improving safety and automation levels.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0020] This utility model provides an intelligent monitoring system for septic tanks based on sensor data. The system is mainly used in urban or rural sewage pretreatment facilities, and is especially suitable for remote, intelligent and automated monitoring of the operating status of closed septic tanks, so as to solve the problems of single monitoring methods, slow response and frequent safety hazards in the existing technology.

[0021] like Figure 1 As shown, the system comprises several key functional components, including a septic tank body 1, several types of sensor modules 2, a data acquisition unit 3, a main control and processing unit 4, a wireless communication module 5, a remote terminal device 6, a power supply device 7, and a protective casing 8. The septic tank body 1 is a traditional sewage pretreatment device, with its internal space divided into a gas zone and a liquid zone according to its operating state.

[0022] like Figure 2As shown, the sensing module 2 is arranged in key parts of the septic tank, specifically including a gas sensor 21 located in the upper gas area of ​​the septic tank (for detecting the concentration of harmful gases such as methane and hydrogen sulfide), a liquid level sensor 22 located at the liquid surface (for determining whether the liquid level exceeds the limit), and a temperature and humidity sensor 23 located in the middle or lower part of the tank (for monitoring the impact of environmental changes on the fermentation state inside the tank). These three types of sensors are electrically connected to the external data acquisition unit 3 via wires to transmit raw monitoring data in real time.

[0023] The data acquisition unit 3 is used to uniformly format various analog or digital signals and send them to the main control processing unit 4. The main control processing unit 4, as the core of the system, integrates functional subunits such as a data receiving module, a data analysis module 41, an alarm judgment module, a communication control module, and a storage module. Specifically, the data receiving module receives multi-source data from the acquisition unit; the data processing module performs multi-dimensional judgments on gas concentration, liquid level, temperature and humidity changes; the alarm judgment module determines whether there are situations such as excessively high liquid levels or abnormal gas concentrations based on preset safety thresholds, triggering an alarm mechanism if these exceed the warning line; the communication control module is responsible for data interaction with the remote terminal device 6 via the wireless communication module 5; and the storage module records historical monitoring data and alarm records for later traceability and analysis. The terminal device includes a mobile terminal 61 with a monitoring client installed or a remote management platform server 62.

[0024] The main control processing unit 4 sends the processed status data and abnormal alarm information to the remote terminal via the wireless communication module 5 (optionally NB-IoT, LoRa, or other low-power wide-area communication protocols), such as... Figure 1 As shown, the terminal can be a mobile terminal 61 for management personnel, a computer client, or a central server, etc., and is equipped with a visual monitoring interface. This interface can display various real-time data curves, historical trend charts, and alarm logs, and supports remote parameter configuration and record export functions. The main control processing unit 4 is equipped with an alarm threshold module 42, which generates an alarm signal 43 when any sensor parameter exceeds a set threshold. The alarm signal 43 includes an audible and visual alarm signal 43 and remote push information.

[0025] like Figure 1As shown, to ensure the system's independent operation in outdoor environments without mains power, the power supply device 7 consists of a solar panel 71, a battery 72, and a power management module. The solar panel 71 is installed above or near the septic tank and automatically charges the battery 72 based on illuminance. The battery 72 then stably supplies power to the main control unit, sensor module, and communication module. The power management module can monitor the battery status in real time and optimize its management. Furthermore, the entire data acquisition unit 3, main control unit, and power supply module are integrated into a single protective housing 8. This housing 8 has an IP-rated dust and water resistance rating, strong corrosion resistance, and is suitable for long-term deployment in humid and harsh environments outside or near septic tanks, preventing damage to electronic components. The power supply device 7 further includes a power monitoring unit 73, used to detect the remaining power of the battery 72 and feed it back to the main control processing unit 4.

[0026] In practical applications, when the liquid level exceeds the threshold or an abnormal gas concentration is detected, the system will immediately push an alarm message to the management terminal. Simultaneously, it can be linked to an external audible and visual alarm or an automatic exhaust valve 11 (as an optional expansion module), effectively reducing the risk of accidents. The system features a compact and modular design, facilitating installation and maintenance, and possesses excellent scalability. For example, it can be further enhanced with pH sensors, dissolved oxygen sensors, etc., to suit more environmental scenarios.

[0027] In summary, this utility model, by integrating multiple types of sensors, an intelligent main control module, a remote communication unit, and a self-powered module, realizes functions such as multi-parameter perception of septic tank status, intelligent judgment of anomalies, remote information transmission, and historical data recording. It improves the intelligence level and operational safety of the sewage pretreatment system and has significant beneficial effects such as reasonable structure, stable operation, fast response, and strong adaptability.

[0028] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
