Description

Technical Field

[0002] The municipal utility facilities built underground in the city for laying municipal utility pipelines are called cable corridors, which are implemented with unified planning, design, construction and maintenance. Communication cables are a type of cable that must be considered in the design of comprehensive pipeline corridors.

[0003] Communications cables consist of multiple insulated wires or conductors forming a core, enclosed by a sealed sheath. Some cables also have an outer sheath. They can be laid in various ways, including overhead, buried, in pipelines, and underwater. They are categorized by structure as symmetrical, coaxial, and composite cables; and by function as field and permanent cables (underground and submarine cables). Communications cables offer a wide transmission bandwidth, high communication capacity, and minimal interference, but are difficult to repair. They can transmit telephone calls, telegrams, data, and images.

[0004] Gases are generated when the composition or materials within a cable change. The conductors, insulation, and fillers within the cable may undergo chemical reactions such as oxidation, decomposition, and polymerization. These reactions can produce various gases, such as hydrogen, oxygen, and carbon dioxide. External forces applied to the cable during construction or use can cause pressure changes. Excessive pressure on the cable can reduce the distance between molecules within the cable, which can also lead to gas generation. Utility Model Content

[0024] See also Figure 1-4 The utility model provides a technical solution: a comprehensive monitoring device for a cable corridor with a gas analysis function, comprising a monitoring box 1, a gas analysis device 2 is arranged in the monitoring box 1, a sample chamber 3 is provided on one side of the gas analysis device 2, a cooling fan 4 is provided at the bottom of the monitoring box 1, and a driving power supply 5 is also provided at the bottom of the monitoring box 1. The gas analysis device 2 includes an infrared light source 6, an infrared detector 7, a signal preprocessing module 8 and a pressure control and monitoring module 9. A display screen 10 is provided on the top of the monitoring box 1. The signal preprocessing module 8 includes a signal amplifying circuit 11 and a filtering circuit 12. The signal amplifying circuit 11 is connected to the filtering circuit 12. The signal amplifying circuit 11 receives an electrical signal, and the filtering circuit 12 outputs a preprocessed signal. The gas analysis device 2 also includes a microprocessor 13, which is respectively connected to the signal preprocessing module 8 and the pressure control and monitoring module 9.

[0025] Specifically, the gas analysis device 2 also includes a communication interface module 14 and a data display module 15, both of which are connected to the microprocessor 13. The provision of these modules significantly enhances the data interaction and display capabilities of the cable corridor integrated monitoring device. The communication interface module 14 utilizes a standardized design, enabling real-time and accurate transmission of monitoring data to a designated platform, facilitating centralized monitoring and analysis by management personnel, enabling timely identification of potential issues and the implementation of appropriate measures.

[0026] Specifically, the data display module 15 is electrically connected to the display screen 10 , and the data display module 15 is responsible for intuitively displaying various parameters detected by the gas analysis device 2 , such as gas concentration, pressure value, temperature, etc., on the display screen 10 on the top of the monitoring box 1 .

[0027] Specifically, a filter 16 is further provided outside the sample chamber 3. By providing the filter 16, the gas is preliminarily purified to remove impurities such as dust and large particles therein, thereby protecting subsequent analysis elements from contamination and improving the accuracy of gas analysis.

[0028] Specifically, a sponge layer 17 is fixedly installed on one side of the filter 16. By providing the sponge layer 17, the gas sample passes through the sponge layer 17 and further absorbs moisture and tiny particles, ensuring that the gas entering the sample chamber 3 is pure and dry.

[0029] Specifically, the infrared light source 6 is an infrared light emitting diode, an infrared laser or a thermal radiation infrared light source 6 .

[0030] Specifically, the sample chamber 3 is a sealed light-proof dark chamber. The sample chamber 3 is designed to be a sealed light-proof dark chamber, which makes the gas analysis accuracy more accurate.

[0031] Specifically, the infrared detector 7 is a thermal detector or a photon detector.

[0032] A specific application example of this embodiment is:

[0033] During use, the entire monitoring device is powered by a driver power supply 5, ensuring the proper functioning of all modules. To monitor the gas composition within the cable corridor, the gas analyzer 2 is activated. At this point, the cooling fan 4 begins operating, effectively dissipating heat generated by the various components within the monitoring box 1 and ensuring stable system operation.

[0034] The door of sample chamber 3 automatically opens, allowing the gas sample from the corridor to enter through filter 16. Filter 16 initially purifies the gas, removing impurities such as dust and large particles, thereby protecting subsequent analytical components from contamination. The gas sample then passes through sponge layer 17, which further absorbs moisture and fine particles, ensuring that the gas entering sample chamber 3 is pure and dry.

[0035] Inside the sealed, light-proof sample chamber 3, infrared light source 6 is activated. Depending on the design, an infrared light emitting diode, infrared laser, or thermal radiation infrared light source 6 can be used, depending on the characteristics of the gas components to be analyzed. The infrared light emitted by infrared light source 6 passes through the gas sample and interacts with specific gas molecules in the sample, such as through absorption and scattering. These changes are captured by infrared detector 7.

[0036] Infrared detector 7, a key analytical element, can be either a thermal or photon detector. Leveraging its high sensitivity and accuracy, it converts received infrared light signals into electrical signals. These electrical signals then enter signal preprocessing module 8, where they are amplified by signal amplifier circuit 11 to enhance signal strength. Filter circuit 12 then removes noise and interference, ensuring signal purity and accuracy.

[0037] The pre-processed signals are transmitted to the microprocessor 13, which is the core of the gas analysis device 2 and is responsible for processing and analyzing these signals. It uses preset algorithms and models to calculate the concentrations of various components in the gas sample and stores the results in internal memory.

[0038] At the same time, the microprocessor 13 also exchanges data with external devices through the communication interface module 14, such as transmitting monitoring results to a remote monitoring center in real time, enabling remote monitoring and data analysis. In addition, after receiving instructions from the microprocessor 13, the data display module 15 displays the monitoring results in an intuitive manner on the display screen 10, allowing on-site personnel to quickly view and record them.

[0039] The device also has a pressure control and monitoring module 9, which can monitor the pressure in the sample chamber 3 in real time to ensure that the analysis process is carried out under a stable pressure environment. If the pressure is abnormal, an alarm mechanism will be automatically triggered to remind the operator to take timely action.
