Description

Technical Field

[0001] The utility model belongs to the technical field of environmental monitoring, and in particular relates to a biogas detection device. Background Art

[0002] In recent years, a large number of rural biogas projects have been rapidly promoted and implemented in cold northern regions. Using agricultural and domestic waste as raw materials, biogas can be produced to provide energy for daily life and production. This biogas can be used in agricultural production, achieving a virtuous cycle of planting, breeding, and processing, thereby reducing environmental pollution. Biogas is a flammable mixture composed primarily of methane and carbon dioxide. If not properly managed, it can easily accumulate. When concentrations reach a certain level, leaks can cause poisoning. Exposure to open flames can easily lead to explosions, resulting in casualties and endangering the safety of people and property. Measuring biogas composition is crucial for maintaining the normal operation of biogas projects and ensuring their proper use. Therefore, establishing an efficient, networked monitoring and early warning platform for rural biogas projects is of great practical significance for the safe utilization of biogas energy, improving the efficiency of biogas utilization supervision, and improving service quality.

[0003] Underground gas pipeline leaks are typically detected by testing a single gas. However, biogas is composed of methane (50% to 80% by volume), carbon dioxide (20% to 40% by volume), nitrogen (0% to 5% by volume), hydrogen (less than 1% by volume), oxygen (less than 0.4% by volume), and hydrogen sulfide (0.1% to 3% by volume). Therefore, a single gas alone cannot be used to determine a gas leak. Based on the composition of biogas, it is necessary to simultaneously test the concentration of carbon dioxide to determine whether the detected methane gas is biogas. Existing technologies mostly only detect a single gas to determine if a gas leak is present. However, underground, organic matter in an oxygen-free environment produces biogas through microbial fermentation. Biogas contains a large amount of methane. Therefore, detecting methane alone is not enough to confirm a gas leak. Carbon dioxide, the second largest component in biogas, must also be tested to determine whether the methane is from the biogas. This device uses both methane and carbon dioxide sensors to monitor both gases, making it suitable for biogas detection.

[0004] In the actual working environment of biogas detection, if the posture of the biogas detection device changes, affecting the detection of methane and carbon dioxide sensors, for example: the detection device vibrates or tilts beyond the set threshold, or is flooded, etc., it will affect the accuracy of the actual biogas detection results.

[0005] In order to solve the above problems, it is necessary to improve the existing technology and design an intelligent device with a long standby time, a liquid crystal display of device status information, and the ability to detect biogas.

[0006] In view of this, the present utility model is proposed. Utility Model Content

[0012] Furthermore, the posture detection module also includes a water immersion sensor, and the posture information also includes water level height information outside the detection device detected by the water immersion sensor; if the main controller determines that the received water level height information outside the detection device exceeds a set threshold, an alarm abnormality signal is issued.

[0013] Furthermore, the water immersion sensor is provided with a sampling gas chamber; the gas in the sampling gas chamber forms a greater pressure to prevent water from flowing into the water immersion sensor.

[0014] Furthermore, the posture detection module also includes a temperature sensor for detecting temperature; a pressure sensor for detecting pressure around the biogas detection device; the main controller determines whether the detected gas is biogas or methane based on the temperature and the pressure around the detection device.

[0015] Furthermore, a timer is set inside the detection device to set a set time. After the detection device is awakened, the sensor module and the posture detection module detect at least twice; the main controller wakes up the posture detection module every set time to detect the posture information of the detection device.

[0016] Furthermore, the detection device also includes a display module, which is used to display the concentration values ​​of carbon dioxide and methane and / or the alarm information; the alarm information at least includes that the detected gas is biogas or methane and / or the detection device tilts beyond a threshold and / or vibrates beyond a set threshold and / or the water level outside the detection device exceeds a set threshold.

[0017] Furthermore, the detection device also includes a communication module, which is respectively communicated with the posture detection module, the sensor module and the main controller; the main controller sends the posture information of the detection device and the carbon dioxide and methane information to the terminal or third-party platform through the communication module.

[0018] Furthermore, the detection device also includes a positioning module, which is communicatively connected to the main controller; if the main controller determines that the received vibration information exceeds a set threshold, it will alarm an abnormality signal; and the location of the biogas detection device is sent to a terminal or a third-party platform through the positioning module.

[0019] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art.

[0020] This application integrates multiple sensors, including carbon dioxide sensors, methane sensors, temperature sensors, and pressure sensors, to achieve multi-parameter monitoring of biogas and its production environment, improving the comprehensiveness and accuracy of detection. Vibration sensors and tilt sensors can be used to monitor the operating status and placement angle of the detection device in real time, helping to determine the validity and accuracy of the detection data.

[0021] When an abnormal situation is detected, such as biogas leakage or abnormal vibration of the equipment, the alarm module can convey the relevant information to the relevant personnel through the communication module, and can provide the current location information of the detection equipment through the GPS positioning system.

[0029] Example 1

[0030] A biogas detection device includes a main controller, a sensor module, a communication module, a storage module, an alarm module, a display module, and a power module. The sensor module includes: for detecting gas concentration, at least an infrared carbon dioxide sensor and a laser methane sensor. During the detection process, the concentrations of methane and carbon dioxide detected by the sensor module will be transmitted to the main controller in real time; the main controller will calculate the concentration ratio of carbon dioxide and methane based on the detected carbon dioxide concentration and methane concentration, and compare it with the concentration ratio of the two in biogas. By analyzing this ratio, combined with pre-set thresholds and conditions, the main controller can determine whether the gas in the current environment is biogas or pure methane; the specific system structure diagram is as follows Figure 1 As shown, in this embodiment, the main controller interacts with the sensor module, receives the gas concentration information of the sensor module and stores the information of the sensor module in an external Flash storage, and then sends the information of the sensor module to a third-party device end through the communication module. The third-party device end includes but is not limited to a remote device or server.

[0031] In this embodiment, this judgment is crucial to ensuring the safe operation of the biogas project because it can help relevant personnel accurately identify the source of the gas and take appropriate measures. For example, if the detected gas is mainly methane rather than biogas, this may indicate a leak or other problem that requires timely repair. In addition, the communication module in the detection device allows this data to be transmitted to a remote monitoring platform or relevant management personnel in real time. The alarm module and display module can immediately issue visual and / or audible alarms when abnormal conditions are detected, such as gas concentration exceeding the safe range or gas type mismatch, prompting on-site personnel to take action. Finally, the power module provides the necessary energy for the entire system.

[0032] In this embodiment, the main controller is responsible for coordinating and processing all tasks in the entire system, including collecting data from the sensor modules, storing it in the external Flash memory, transmitting data via the communication module, and controlling the alarm and display modules. The communication module includes, but is not limited to, Wi-Fi, Bluetooth, cellular networks, etc., and is used to transmit data processed by the main controller to a remote device or server.

[0033] In this embodiment, the sensor module boasts high sensitivity and selectivity, capable of handling harsh underground environments. Specifically, it comprises at least two key sensors: a methane sensor and a carbon dioxide sensor. The methane sensor utilizes an advanced laser methane sensor based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) technology. This sensor boasts exceptional performance, being resistant to high humidity environments, operating stably over a wide temperature range, and avoiding cross-gas interference. This enables precise detection of methane concentrations in a variety of complex spatial environments, ensuring the accuracy of the device. The carbon dioxide sensor, on the other hand, utilizes infrared absorption principles and can also accurately measure carbon dioxide concentrations in a variety of environments. This is crucial for determining whether methane originates from biogas, as biogas contains not only a large amount of methane but also a certain proportion of carbon dioxide. The combined use of these two sensor designs enables the device to not only monitor a single gas, but also simultaneously detect the presence of both methane and carbon dioxide, enabling more accurate determination of gas leaks in underground environments and whether the leaked gas is biogas. This comprehensive monitoring approach improves diagnostic reliability and accuracy, reduces the risk of false alarms, and provides a more scientific basis for safety assessments of underground environments.

[0034] In this embodiment, the detection device is provided with a posture detection module and a positioning module; the posture detection module is communicatively connected to the main controller, and the posture detection module is used to detect the posture information of the biogas detection device; the posture detection module includes at least a vibration sensor, the task of which is to sense vibrations exceeding a set threshold that occur during the operation of the detection device. When the vibration sensor detects vibrations exceeding the threshold, it will immediately trigger an external I / O interrupt. When the sampled value is greater than a first set value, it is determined that the detection device has been moved; at this time, the processor on the mainboard of the detection device is forced to wake up from a dormant state, and the processor immediately starts the positioning module built into the detection device. The positioning module can be set to a GPS positioning system to obtain the current precise geographic location information of the detection device. Subsequently, the current location information of the detection device is sent to the main controller, and the main controller maintains communication with the terminal or third-party platform through the built-in communication module. Once the location information of the detection device is received, the main controller will immediately forward this data to the terminal or client. The client can be an operator at the ground control center or any authorized user of the remote monitoring system. In this way, even in a complex underground environment, the position of the detection device can be tracked in real time to ensure timely response when an abnormal situation occurs; this design helps to achieve a rapid response mechanism.

[0035] In this embodiment, in order to improve the protection capability and adaptability of the detection device, the detection device also includes a water immersion sensor. The design of the sensor module combined with the sampling gas chamber of this application provides an effective safety barrier for the device. When it is detected that water has flooded the device, the water immersion sensor responds quickly. At this time, the residual gas in the sampling gas chamber generates a higher relative pressure due to the increase in external water pressure, forming a natural barrier that can prevent moisture from further invading the sensor. This design of the application itself avoids direct contact between the sensor and water, reduces the risk of damage due to water immersion, and ensures the long-term stability of the sensor and the accuracy of the test results. In addition, the device meets the IP68 protection level standard, which means that it can withstand strong impacts and long-term flooding, especially in rainy seasons or humid environments. It can maintain good sealing performance to prevent water and dust from entering the interior of the device, thereby ensuring that the device can work normally in harsh environments.

[0036] In this embodiment, in addition to basic methane gas detection functionality, the detection device also includes a tilt sensor within its posture detection module. The posture information also includes information about the device's tilt, as detected by the tilt sensor. The tilt sensor monitors the device's placement angle to ensure optimal operating conditions. When the device experiences an abnormal tilt exceeding a set threshold, the tilt sensor activates and immediately transmits this information to the device's internal motherboard. The motherboard's processor then wakes from sleep mode to process the signal from the tilt sensor. After confirming that the device has tilted, the processor sends an alarm to remote maintenance personnel via a built-in wireless module. This alarm includes a "device tilt event," notifying maintenance personnel that the device may be in danger due to improper installation or environmental factors on site. Receiving the alarm, maintenance personnel can quickly respond and make on-site adjustments and repairs. This ensures that the device can continue to accurately perform its methane gas detection tasks while preventing moisture intrusion caused by tilt. By integrating the tilt sensor on the detection device, the present application can ensure that the detection device provides additional safety protection in the event of flooding or other emergency situations, thereby improving the stability and reliability of the entire system.

[0037] In this embodiment, if Figure 1 As shown, the core of the device is the main controller, which is the main control chip. The main controller puts most electronic components into standby mode during inactivity, significantly reducing energy consumption. The main controller is equipped with an internal timer for setting a set time, allowing the detection device to enter a low-power state without the need for continuous activity. Specifically, the timer wakes up the posture detection module and sensor module at preset time intervals to detect the posture information of the detection device and the carbon dioxide and methane concentrations. This allows the device to perform detection tasks periodically, ensuring a balance between real-time monitoring and energy saving.

[0038] Each time the attitude detection module and the sensor module are awakened, all sensors will be activated for several detailed tests. These tests include but are not limited to key parameters such as carbon dioxide and methane concentrations, ambient temperature, humidity and air pressure, as well as the attitude information of the detection device. After the detection data is processed by the processor, it will be transmitted to the remote monitoring platform or terminal device through a communication module (such as a cellular network or satellite communication module). After the data upload is completed, the detection device will not remain active, but will automatically return to standby mode. In this standby mode, the power supply of some components will be cut off, including but not limited to the display, some peripheral interfaces and non-critical auxiliary circuits. This design further reduces the power consumption of the device during standby and enhances the overall energy efficiency of the system. This working mode not only ensures the real-time and accuracy of biogas detection, but also greatly extends the independent operation time of the device in an unmanned environment. This is especially important for detection points deployed in remote areas or where frequent power supply is not easy. By intelligently managing power supply and utilizing efficient low-power technology, the biogas detection device in this embodiment demonstrates excellent performance and environmental protection characteristics.

[0039] In this embodiment, the storage module is used to temporarily or long-term store sensor data for subsequent analysis and processing. For example, an external Flash memory can be used to compress the data stored in the external Flash memory to improve storage efficiency.

[0040] In this embodiment, the detection device also includes an alarm module. When an abnormal situation is detected (such as biogas leakage, excessive temperature or abnormal humidity, etc.), the alarm module will issue a sound or light warning; for example: when the equipment tilts, the tilt sensor is triggered, the main controller is awakened from the sleep state, and the equipment tilt signal is sent through the communication module. After receiving the equipment tilt alarm signal, the maintenance personnel arrive at the scene and correct the angle of the equipment in time to prevent the air cavity from tilting when the equipment is submerged in water, causing part of the detection device to be flooded.

[0041] In this embodiment, the detection device further includes a communication module, which is respectively connected to the posture detection module, the sensor module, and the main controller; the main controller transmits the posture information of the detection device, as well as the carbon dioxide and methane information, to a terminal or a third-party platform via the communication module. The detection device further includes a positioning module, which is connected to the main controller; if the main controller determines that the received vibration information exceeds a set threshold, it generates an abnormality alarm signal; and the positioning module transmits the location of the detection device to the terminal or a third-party platform.

[0042] In this embodiment, the posture detection module is also integrated with a temperature sensor, and the detection device also includes the following: The biogas production process usually occurs under certain temperature conditions. The optimal fermentation temperature helps to improve the output and efficiency of biogas. Temperature changes may also affect the composition and concentration of biogas. By monitoring the temperature, the operator can make timely adjustments to maintain the optimal fermentation environment. At the same time, potential problems can also be discovered early. For example, too high or too low temperature may cause a decrease in biogas production or abnormalities in the fermentation process. A pressure sensor is also provided in the housing of the detection device to detect the pressure around the biogas detection device. Maintaining appropriate pressure is a key factor in ensuring stable biogas production and safe transportation. Excessive pressure may cause damage to the storage tank or pipeline, while too low pressure may affect the use effect of the biogas. By monitoring the pressure in real time, the operator can adjust the pressure to avoid potential safety hazards.

[0043] In this embodiment, the display module is used to display the real-time data of the sensor module, which is convenient for on-site personnel to view the current environmental status. At the same time, in order to save power consumption and other factors, the existing equipment does not have an obvious human-computer interaction interface function and cannot form a good interaction. The detection device of the utility model adopts the function of opening a top window and displaying the device status on an LCD screen. On the basis of ensuring the IP68 protection level and explosion-proof level, it realizes the real-time display of device information, which greatly facilitates personnel installation, debugging and maintenance. Especially in the case of a failure in the communication function of the device, the device without an interface is disassembled to find the cause of the failure, and the device can be intuitively prompted through the screen. The display module in this application can not only display numerical information such as methane concentration, carbon dioxide concentration, temperature, air pressure, time, etc., but also can prompt alarms, faults, settings, Bluetooth, GPS and other states through icons, and ensure low power consumption while having rich display content.

[0044] In this embodiment, the power module includes a 3.7V disposable large-capacity lithium thionyl chloride battery. After the battery voltage passes through a fuse, it can directly power the communication module.

[0045] In this embodiment, the power module also includes an LDO low-dropout linear regulator, which converts the battery voltage into a stable voltage suitable for the operation of the main controller. The power module in this utility model provides a stable power supply for the entire system. Equipment operating in the space adjacent to the gas pipeline requires a battery power supply that lasts as long as possible due to the inconvenience of maintenance. This utility model uses a 3.7V disposable high-capacity lithium thionyl chloride battery for power supply. After the battery voltage passes through the fuse, it can directly power the communication module. After the battery voltage passes through the LDO low-dropout linear regulator, it powers the main controller. The low-power and high-capacity battery pack design adopted by this utility model can greatly increase the service life of the equipment, reduce the maintenance cycle of the device and the cost of battery replacement, and reduce the overall cost of the project.

[0046] In this embodiment, the sensor modules periodically report data to the main controller, which can also request sensor data on demand. This can be optimized by adding scheduling algorithms to reduce data redundancy and optimize energy consumption. To reduce energy consumption and improve communication efficiency, efficient data transmission protocols can be implemented, for example, only sending data through the communication module when new data or important events occur. The alarm module can be customized based on different abnormal conditions to ensure that alarms are triggered in the right circumstances. For example, alarm thresholds can be set by the main controller to avoid unnecessary false alarms.

[0047] In this embodiment, the communication module utilizes the low-power nRF24LO1, achieving longer data transmission distances than WiFi and offering automatic response and retransmission capabilities. Output power, channel selection, and protocol settings can be configured via the SPI interface. The sensor module can be connected to the main controller microcontroller for rapid data transmission to the data display module and terminal devices, enabling remote monitoring of biogas digester temperature, methane, pH, and CO2 concentration.
