Description

Technical Field

[0001] This utility model belongs to the field of monitoring, and specifically relates to a monitoring device for cold air ducts in buildings. Background Technology

[0002] With increasingly stringent requirements for energy conservation and environmental protection in buildings, cold air ducts, as an important component of building ventilation systems, are receiving growing attention. The design and use of cold air ducts directly impact indoor air quality and energy consumption, making monitoring devices increasingly crucial. However, currently available building cold air duct monitoring devices suffer from significant shortcomings in several aspects, limiting their effectiveness and reliability in practical applications.

[0003] Many existing monitoring devices use outdated sensor technology, making it impossible to monitor key parameters such as temperature, humidity, and wind speed within the air conditioning duct in real time and accurately. This technological lag affects the accuracy and timeliness of monitoring data, making it impossible to effectively determine the operating status of the air conditioning duct, which in turn affects indoor comfort and air quality.

[0004] Most current monitoring devices lack intelligent analysis and processing capabilities, failing to perform in-depth analysis and real-time feedback of collected data. When faced with complex environmental changes, existing systems often cannot automatically adjust ventilation strategies or issue alarms, leading to decreased ventilation efficiency, or even over- or under-ventilation, wasting energy and negatively impacting the indoor environment. Furthermore, many monitoring devices lack modularity and scalability in their design, resulting in numerous difficulties during technology upgrades or system expansion. This lack of forward-looking design makes existing equipment ill-suited to future technological development needs, increasing maintenance and upgrade costs. Moreover, the user interface design of existing monitoring devices is often unfriendly and complex, potentially causing difficulties for users and hindering the effective use of the equipment's functions. Simultaneously, the lack of intuitive data display and alarm functions makes it difficult for users to react promptly to abnormal situations, affecting the safety and reliability of the access routes.

[0005] Current monitoring devices also have shortcomings in terms of environmental adaptability. Many devices fail to effectively withstand the effects of harsh environments, such as high humidity, low temperature, or dust, leading to performance degradation or even malfunction. Therefore, to address these technical deficiencies, there is an urgent need to develop a new type of building cold air duct monitoring device that can achieve high-precision real-time monitoring, intelligent data analysis and feedback, a user-friendly interface, and good environmental adaptability. This would improve the operating efficiency of cold air ducts and the comfort of the indoor environment, meeting the high standards of modern building ventilation systems. Utility Model Content

[0006] This invention proposes a monitoring device for building cooling ducts, which solves the problems of inconvenient temperature monitoring and data transmission delay in cooling ducts. Through real-time temperature monitoring and data transmission, it improves the management efficiency and operational safety of the cooling system.

[0007] The technical solution of this utility model is implemented as follows: A monitoring device for a building's cold air duct includes through holes opened above two adjacent cold air ducts, with temperature sensors installed in the through holes. The temperature sensors are mounted on a fixed frame, with the upper end face of the fixed frame connected to a connecting frame. One end of the connecting frame is connected to the fixed frame, and the other end is connected to a horizontal rod. The horizontal rod is installed on the cold air duct, and a monitoring box is installed in the middle of the upper end face of the horizontal rod. The monitoring box contains a data monitor and a communication module. The data monitor records historical data from the temperature sensors, and the communication module transmits the data recorded by the data monitor to a backend server.

[0008] Traditional cold air aisle monitoring systems often rely on distributed temperature sensors, which are typically installed in hard-to-reach locations, complicating maintenance and monitoring. This system, however, significantly simplifies the installation and maintenance process by creating through-holes above adjacent cold air aisles and installing temperature sensors there. The centralized mounting of the temperature sensors on a fixed bracket facilitates inspection and replacement, improving the overall operability of the system.

[0009] Existing technologies often lack real-time monitoring and analysis of temperature data. Traditional temperature monitoring equipment may only have basic temperature acquisition functions, lacking the recording and analysis of historical temperature data. However, the data monitoring instrument built into this monitoring device can record historical data from the temperature sensor in real time and transmit the data to the backend server via a communication module. This real-time data recording and transmission capability allows managers to promptly obtain information on temperature changes in the cold air duct, enabling rapid responses and ensuring the efficient operation of the system.

[0010] Existing monitoring systems often rely on wired connections for data transmission, limiting their flexibility and scalability. This device design, however, utilizes a communication module to wirelessly transmit data to the backend server, reducing reliance on physical cables. This design not only enhances system flexibility but also facilitates the deployment and expansion of the monitoring network in different environments, allowing users to easily adjust sensor locations or add new monitoring points as needed.

[0011] Existing technologies also have shortcomings in terms of accuracy and stability in temperature monitoring. Many traditional sensors can be affected by changes in environmental conditions, leading to inaccurate measurement results. This system, by mounting the temperature sensor on a fixed frame, provides a more stable measurement environment and reduces the impact of external factors on the sensor. Furthermore, the frame design effectively reduces vibration, further improving the sensor's measurement accuracy.

[0012] Traditional air duct monitoring systems often lack data analysis and intelligent decision support. Existing technologies generally only provide basic temperature monitoring functions and cannot perform in-depth data analysis. This monitoring device, however, transmits historical data to a backend server and, combined with big data analytics, can analyze temperature trends in the air ducts, helping managers identify potential faults and optimize system operation. This intelligent data analysis capability will provide more scientific and effective support for building air duct management.

[0013] In a preferred embodiment, the fixing frame includes a fixing base plate and a fastening plate. Fastening screws are provided on the four corners of the fastening plate, and an annular fixing frame is installed in the middle of the upper surface of the fastening plate, which is connected to the connecting frame.

[0014] In a preferred embodiment, the connecting frame includes an L-shaped connecting rod and a hydraulic damping rod. One end of the L-shaped connecting rod is connected to the fixed frame, and the other end is connected to the hydraulic damping rod. The other end of the hydraulic damping rod is connected to the horizontal bar.

[0015] In a preferred embodiment, the horizontal bar is a groove structure with an open front end, and a movable slider is provided at the connection position between the hydraulic damping rod and the horizontal bar, so that the movable slider can move within the groove.

[0016] In a preferred embodiment, a transmission hole is provided on the side end face of the monitoring box. The wiring harness of the data detector in the monitoring box is led out through the transmission hole and connected to the temperature sensor through the wiring harness to receive data from the temperature sensor.

[0017] The beneficial effects of adopting the above technical solution are as follows: By centrally installing temperature sensors, the system can achieve comprehensive monitoring of the cooling air duct, ensuring real-time understanding of temperature changes. Timely acquisition of temperature data helps managers quickly identify the operating status of the cooling system, avoiding equipment failures caused by abnormal temperatures, thereby reducing maintenance costs and downtime. This real-time monitoring capability greatly improves the management efficiency and safety of building cooling air ducts.

[0018] The built-in data monitoring and communication modules enable real-time recording and transmission of temperature data to the backend server, providing a foundation for subsequent data analysis. This data traceability and historical recording capability helps managers better understand the long-term operational status of the cooling system and develop more reasonable maintenance and management plans by analyzing temperature data trends. This scientific management approach will improve the building's energy efficiency and reduce unnecessary energy consumption.

[0019] The system's wireless communication capabilities enhance the flexibility of the monitoring device, making installation and deployment in different environments more convenient. Traditional wired monitoring systems often require complex wiring, increasing construction difficulty and cost. This device's design allows for flexible installation in different locations, enabling users to adjust it according to their actual needs. This flexibility allows the monitoring system to adapt to buildings of different sizes and types, providing users with more options.

[0020] The mounting bracket design not only improves the stability of the temperature sensor and reduces external interference, but also effectively extends the sensor's lifespan and reduces maintenance costs due to equipment failure. This design takes into account the long-term use of the equipment, further enhancing the system's reliability.

[0021] By combining historical data with modern big data analytics, the system provides intelligent decision support for the management of air-conditioning ducts. This intelligent management not only improves the operational efficiency of the air-conditioning system but also provides data support for energy conservation and emission reduction in buildings, aligning with current societal pursuit of sustainable development. In conclusion, this consumer data-driven unmanned vending machine operation system, through innovative design and efficient technological application, provides a comprehensive, flexible, and intelligent solution for building air-conditioning management, significantly improving system operational efficiency and safety.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] like Figure 1 As shown, a monitoring device for a building's cold air duct includes through holes above two adjacent cold air ducts, with temperature sensors installed in the through holes. The temperature sensors are mounted on a fixed frame 1, with a connecting frame 2 connected to the upper surface of the fixed frame 1. One end of the connecting frame 2 is connected to the fixed frame 1, and the other end is connected to a horizontal rod 3. The horizontal rod 3 is installed on the cold air duct, and a monitoring box 4 is installed in the middle of the upper surface of the horizontal rod 3. The monitoring box 4 contains a data monitor 41 and a communication module 42. The data monitor 41 records historical data from the temperature sensors, and the communication module 42 transmits the data recorded by the data monitor 41 to a backend server.

[0029] The core of the device is a temperature sensor, installed above two adjacent cold air ducts, which collects data through through-holes. The selection and installation location of the temperature sensor are crucial; it needs to be located above the cold air ducts, capable of accurately monitoring temperature changes in the cold air. This monitoring location ensures timely acquisition of environmental information within the cold air ducts for subsequent analysis.

[0030] The temperature sensor is fixed to the mounting bracket 1. This fixing method ensures that the sensor will not shift its position due to vibration or airflow during monitoring, thereby improving measurement accuracy. The upper end of the mounting bracket 1 is connected to the connecting bracket 2, and the other end of the connecting bracket 2 is connected to the horizontal bar 3, forming a stable support structure to ensure the stability of the monitoring equipment. The horizontal bar 3 is installed at the top of the cold air duct, providing necessary support for the entire monitoring device.

[0031] A monitoring box 4 is installed in the middle of the horizontal bar 3, which integrates a data monitoring unit 41 and a communication module 42. The main function of the data monitoring unit 41 is to record historical data collected by the temperature sensor and perform real-time monitoring. By continuously collecting temperature data, the data monitoring unit can generate temperature change curves to help managers analyze the performance of the cooling air duct. At the same time, the data monitoring unit can also set alarm thresholds. When the temperature exceeds the set range, the system can automatically send an alarm to prompt managers to make corresponding adjustments.

[0032] The communication module 42 is responsible for transmitting the data recorded by the data monitoring device to the back-end server in real time. Through wireless or wired networks, the device can upload important temperature data to the cloud or local server for subsequent data analysis and storage. This real-time data transmission capability allows managers to access the temperature information of the cooling ducts anytime, anywhere, enabling remote monitoring and management, thus improving the intelligence and efficiency of building operations.

[0033] The entire workflow is as follows: Initially, the temperature sensor starts working, periodically collecting temperature data within the cooling air duct. The data monitoring unit 41 receives and records this data, forming historical data records. Simultaneously, the communication module 42 uploads this real-time data to the backend server, enabling effective data storage and analysis. Management personnel can view the temperature conditions of the cooling air duct and the trend analysis of historical data at any time through dedicated software or applications. When the temperature is abnormal, the system automatically triggers an alarm, notifying management personnel to handle the situation promptly and ensure the normal operation of the building's cooling system.

[0034] This monitoring device for building cooling ducts, through its rational structural design and precise data acquisition and transmission mechanism, can monitor and record temperature changes in the cooling ducts in real time, improving the efficiency and intelligence of building ventilation management and providing strong support for ensuring a comfortable environment inside buildings.

[0035] The fixing frame 1 includes a fixing base plate 11 and a fastening plate 12. Fastening screws 13 are provided on the four corners of the fastening plate 12. An annular fixing frame 14 is installed in the middle of the upper surface of the fastening plate 12 and is connected to the connecting frame 2 through the annular fixing frame 14.

[0036] The mounting bracket design includes a base plate and a fastening plate. Fastening screws are located at the four corners of the fastening plate, and a ring-shaped fixing bracket is installed in the center of the upper surface. This structural design offers higher stability and reliability compared to existing mounting brackets. Traditional mounting brackets often use simple bolts or welding for fixation, which can easily lead to unstable connections or loosening. This solution, by using fastening screws at the four corners of the fastening plate, ensures that the mounting bracket can bear force evenly, enhancing the rigidity of the overall structure. Furthermore, the ring-shaped fixing bracket design makes the connection with the connecting frame more secure, reducing the risk of loosening due to vibration or external forces during operation, thereby improving the safety and durability of the equipment.

[0037] The connecting frame 2 includes an L-shaped connecting rod 21 and a hydraulic shock absorber 22. One end of the L-shaped connecting rod 21 is connected to the fixed frame 1, and the other end is connected to the hydraulic shock absorber 22. The other end of the hydraulic shock absorber 22 is connected to the horizontal bar 3.

[0038] The design of the connecting frame incorporates a combination of L-shaped connecting rods and hydraulic damping rods. This structural design offers superior vibration damping compared to existing single-connection methods. Traditional connecting frames often lack effective vibration damping measures, causing the impact forces experienced by the equipment during operation to be directly transmitted, affecting the equipment's stability and lifespan. This solution, through the introduction of hydraulic damping rods, effectively absorbs and mitigates the impact forces from the horizontal bars, enhancing the equipment's seismic resistance. Furthermore, the L-shaped connecting rod design allows for more flexible connections, adapting to different installation spaces and environments, thus improving the overall system's adaptability.

[0039] The horizontal bar 3 has a groove structure with an open front face. A movable slider is provided at the connection point between the hydraulic damping rod 22 and the horizontal bar 3, allowing the horizontal bar to move within the groove. The design of the horizontal bar utilizes a groove structure with an open front face and a movable slider at the connection point between the hydraulic damping rod and the horizontal bar. This design provides greater flexibility compared to the fixed connection method in existing technologies. Traditional horizontal bar designs often limit the movement range of the equipment and are difficult to adapt to complex working environments. This solution, by setting a movable slider within the groove, allows the hydraulic damping rod to slide easily within the horizontal bar, thereby achieving a larger working range and more precise positioning. This flexibility not only improves the ease of operation of the equipment but also enhances the applicability of the system in different application scenarios.

[0040] The monitoring box 4 has a transmission hole on its side end face. The wiring harness of the data detector 4 inside the monitoring box 4 is led out through the transmission hole and connected to the temperature sensor via a wiring harness to receive data from the temperature sensor. This design provides a more convenient connection solution compared to existing data transmission methods. Traditional data transmission methods often require complex wiring, increasing the difficulty of installation and maintenance. This solution simplifies the wiring harness lead-out process by setting a transmission hole, making the connection between the monitoring box and the temperature sensor more direct and efficient, reducing the risk of signal interference and data loss due to improper wiring. Furthermore, this design facilitates later maintenance and replacement, improving the overall maintainability and reliability of the equipment.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
