Description
Technical Field
[0001] This utility model belongs to the field of monitoring technology, specifically relating to a monitoring system for a dry anaerobic fermentation project. Background Technology
[0002] Dry anaerobic fermentation, as a rapidly developing new energy and environmental protection technology in recent years, has shown broad application prospects in fields such as harmless treatment of livestock and poultry manure, resource-based gasification of straw, and volume reduction and disposal of kitchen waste, thanks to its significant advantages such as low requirements for raw material pretreatment, low biogas production, low energy consumption, and convenient management. Its core characteristics lie in maintaining the dry matter content of the fermentation raw materials at 20%–40%, ensuring the raw materials are in solid form, and generating no wastewater during the process. This fundamentally solves the problem of biogas disposal in traditional anaerobic fermentation, and the fermentation residue can be further processed into organic fertilizer, truly achieving zero pollutant emissions while possessing good economic benefits and a positive energy effect. From a resource potential perspective, my country possesses extremely abundant reserves of raw materials for dry anaerobic fermentation. According to surveys, in 2010, the theoretical resource volume of straw nationwide reached 840 million tons, with a collectable resource volume of approximately 700 million tons. The comprehensive utilization rate of straw was 70.6%, with actual utilization reaching approximately 500 million tons. Of this, approximately 122 million tons were used as fuel (including traditional cooking and heating in rural households and new energy applications), accounting for only 17.8%, indicating that a large amount of straw resources remain undeveloped. Currently, the process of building new rural areas in my country has placed higher demands on clean rural energy and environmental governance. Dry anaerobic fermentation of straw, as an important pathway to obtaining bioenergy, is driving the transformation of traditional household biogas digesters into large-scale biogas energy stations. Even considering only the underutilized 300 million tons of straw, combined with other available raw materials, the total usable raw material resources for dry anaerobic fermentation in my country reach 400 million tons, with a theoretical annual biogas production of up to 40 billion cubic meters, representing a huge market potential. However, large-scale dry anaerobic fermentation projects typically involve multiple complex subsystems, including boiler systems, flare systems, pressure swing adsorption systems, fermentation systems, hydrolysis systems, and crushing systems. Furthermore, the plant areas are large, and equipment is widely distributed, posing significant limitations to traditional monitoring methods. Firstly, conventional network cable transmission is limited by communication distance (usually no more than 100 meters), failing to meet the long-distance data transmission needs of large-scale plants. Secondly, traditional monitoring systems lack stable communication assurance mechanisms, easily experiencing data transmission delays and signal interruptions. Moreover, their low equipment integration makes centralized management and logical control difficult, and their high network bandwidth and energy consumption cannot meet the monitoring requirements for the long-term stable operation of dry anaerobic fermentation projects. Therefore, developing a monitoring system with long-distance transmission capabilities, stable communication, high integration, and energy efficiency is crucial for promoting the large-scale application of dry anaerobic fermentation technology.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] Example 1 like Figure 1 As shown: This embodiment provides a monitoring system for a dry anaerobic fermentation project, including: a main station unit, multiple image acquisition units, a communication transmission unit, a display and storage unit, and a protection unit.
[0019] Specifically, the main station unit is located in the server room; the display and storage unit is located in the central control room; and multiple image acquisition units are respectively arranged in various operating work areas of the dry anaerobic fermentation project plant.
[0020] The protection unit can protect the normal operation of the communication transmission unit; the master station unit is connected to multiple image acquisition units through the communication transmission unit; the master station unit is connected to the display storage unit.
[0021] In this embodiment, the main station unit is a hard disk video recorder 2; the image acquisition unit includes multiple cameras 5; the communication transmission unit includes a fiber optic switch 3; the display and storage unit includes a monitor 1; and the protection unit includes a control cabinet and a fiber optic box.
[0022] In practical applications, the control cabinet can enclose the fiber optic switch 3 and the fiber optic transceiver 4; the fiber optic box is used to store the fiber optic cable and prevent the fiber optic cable from bending or breaking.
[0023] In this embodiment, the hard disk recorder 2 integrates an image processing component, a pan-tilt lens component, an alarm component, a network transmission component, and a central processing unit (CPU) component inside its housing. The CPU component is connected to the image processing component, the pan-tilt lens component, the alarm component, and the network transmission component, respectively; the CPU component can also be connected to the communication transmission unit and the display storage unit via the network transmission component.
[0024] The hard disk video recorder 2 is connected to the fiber optic switch 3; the fiber optic switch 3 is connected to multiple cameras 5 respectively; the hard disk video recorder 2 is also connected to the monitor 1; the hard disk video recorder 2 has a built-in hard disk for storing on-site image data; the monitor 1 is connected to the hard disk video recorder 2.
[0025] In this embodiment, all cameras 5 are equipped with Ethernet communication interfaces for collecting on-site images within the dry anaerobic fermentation project area. The on-site images include no-blind-spot monitoring images of the plant area fence and operating status images of the boiler system, flare system, pressure swing adsorption system, fermentation system, hydrolysis system, and crushing system.
[0026] like Figure 2 As shown: In this embodiment, the fiber optic switch 3 is a gigabit-level fiber optic switch; the fiber optic switch 3 has at least two fiber optic ports and multiple network ports; the camera 5 is connected to the network port of the fiber optic switch 3 via a network cable; the fiber optic port of the fiber optic switch 3 is connected to the fiber optic transceiver 4 via an optical fiber; the fiber optic transceiver 4 is connected to the hard disk recorder 2 via a network cable to form a communication link of camera 5-fiber optic switch 3-fiber optic transceiver 4-hard disk recorder 2-monitor 1.
[0027] The above communication link is suitable for scenarios with short communication distances. When the communication distance is greater than 300 meters, a fiber optic transceiver 4 needs to be configured in the middle. The fiber optic transceivers 4 are connected with fiber optic cables, and the rest are connected with network cables.
[0028] For example, such as Figure 1 As shown: The camera 5 can be connected to the fiber optic transceiver 4 via a network cable; the fiber optic transceiver 4 is connected to the fiber optic switch 3 via an optical fiber.
[0029] In practical applications, the camera 5 described in this embodiment includes: an explosion-proof bullet camera, an explosion-proof PTZ camera, and non-explosion-proof bullet cameras and non-explosion-proof PTZ cameras. The explosion-proof bullet camera and the explosion-proof PTZ camera are arranged in the explosion-proof area of the factory; the non-explosion-proof bullet camera and the non-explosion-proof PTZ camera are arranged in the non-explosion-proof area of the factory.

[0031] Example 2 like Figure 1 As shown, this embodiment provides a monitoring system for a dry anaerobic fermentation project, such as... Figure 1 As shown, it includes a hard disk recorder 2, a 16-channel high-definition infrared camera (image acquisition unit), a gigabit fiber optic switch (communication transmission unit), 2 fiber optic transceivers (communication transmission units), a single-mode fiber optic cable (communication transmission unit), 2 27-inch monitors 1 (display and storage units), 4 4TB hard disks (display and storage units), an IP54 protection level control cabinet 8 (protection unit), and 2 fiber optic boxes (protection units). The high-definition infrared camera 5 has a resolution of 4 megapixels, an infrared illumination distance of 80 meters, and an Ethernet communication interface. Eight of the cameras 5 are used for blind-spot-free monitoring of the factory perimeter fence (one camera is deployed every 50 meters). The other eight cameras 5 are used to monitor the boiler system, flare system, pressure swing adsorption system, fermentation system, hydrolysis system, and crushing system, respectively. The gigabit-level fiber optic switch has four fiber optic ports and 24 network ports. Eight network ports are connected to eight factory perimeter fence monitoring cameras 5 via network cables, and the other eight network ports are connected to eight monitoring cameras 5 via network cables. Two fiber optic ports of the fiber optic switch are connected to two fiber optic boxes via single-mode fiber, and then single-mode fiber is led out from the fiber optic boxes to connect to two fiber optic transceivers 4. Two fiber optic transceivers 4 are connected to the hard disk recorder 2 via network cables. The hard disk recorder 2 has four 4TB hard drives installed inside and is connected to two 27-inch monitors 1 via HDMI cables (one for displaying the factory area fence monitoring screen and the other for displaying the operation monitoring screen of multiple systems). The control cabinet contains an encapsulated fiber optic switch and two fiber optic transceivers; two fiber optic boxes are installed in the middle of the factory fence and the area where the subsystem equipment is concentrated, respectively, to accommodate the bent parts of the single-mode fiber. In this embodiment, the maximum communication distance between camera 5 and hard disk recorder 2 is 800 meters. Signal conversion and transmission are achieved through fiber optic transceiver 4 and single-mode fiber, with no data lag. Hard disk recorder 2 supports 16-segment screen preview, which can simultaneously display real-time images from 16 cameras 5. It also monitors the network traffic of each camera 5 in real time through network detection. When a network abnormality occurs in a certain camera 5, it can automatically capture packets and issue an alarm signal. The IP54 protection level of the control cabinet effectively isolates dust and moisture in the central control room. The fiber optic box avoids the problem of single-mode fiber breaking due to its small bending radius. The entire system operates stably and meets the monitoring requirements of this dry anaerobic fermentation project (daily straw processing of 50 tons). Example 3 The difference between this embodiment and Embodiment 2 is that the number of cameras 5 is 32, of which 16 are used for monitoring the factory perimeter fence (one camera every 30 meters), and 16 are used for monitoring subsystems (two cameras per subsystem for redundant monitoring); the fiber optic switch 3 has 8 fiber optic ports and 48 network ports, and is equipped with 4 fiber optic transceivers 4 and 4 fiber optic boxes; the hard disk recorder 2 has 8 6TB hard drives installed (using RAID6 backup mode), and is connected to 4 monitors 1 (2 for fence monitoring and 2 for subsystem monitoring). This embodiment is suitable for large-scale dry anaerobic fermentation projects with a daily straw processing capacity of 100 tons, achieving denser monitoring coverage and more secure data storage, while maintaining gigabit-level system communication speeds without data transmission bottlenecks.
[0032] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
