[0036] like Figure 1 , Figure 2As shown, this utility model embodiment provides a portable multi-functional smart fire inspection device based on the Internet of Things, including a housing 1, a telescopic hand handle 2 at the lower end of the housing 1, and a detachable shoulder strap 3 at the upper end of the housing 1; the front of the housing 1 is provided with a display screen 4, operation buttons 5, a power switch 6, and a charging interface 7; the interior of the housing 1 is provided with a control module 8, a detection module 9, an alarm module 10, an Internet of Things communication module 11, a storage module 12, and a power module 13. The display screen 4, operation buttons 5, detection module 9, alarm module 10, Internet of Things communication module 11, storage module 12, and power module 13 are respectively connected to the control module 8, and the power switch 6 is connected between the control module 8 and the power module 13.
[0037] Specifically, the control module 8 controls the operation of the display screen 4, detection module 9, alarm module 10, IoT communication module 11, storage module 12, and power module 13; the detection module 9 includes a temperature detection unit 901, a smoke detection unit 902, a gas detection unit 903, and an image acquisition unit 904, used for multi-dimensional detection of fire protection facilities and target environment; the alarm module 10 is used to issue an alarm signal when the detection module 9 detects an abnormal signal; the IoT communication module 11 is used to realize data transmission between the control module 8 and an external remote monitoring center; the storage module 12 is used to store the data collected by the detection module 9; and the power module 13 is used to provide power support for the inspection equipment.
[0038] The working principle of the portable multifunctional smart fire inspection equipment based on the Internet of Things in this embodiment is as follows:
[0039] During use, the user inputs a detection command via button 5. The control module 8 then controls the corresponding units in the detection module 9 (temperature detection unit 901, smoke detection unit 902, gas detection unit 903, and image acquisition unit 904) to collect data such as temperature, smoke, combustible or toxic gases, and equipment or environmental images from the fire protection facilities or target environment. The collected data is then transmitted to the control module 8, which compares it with a preset threshold. When the collected data exceeds the preset threshold, an alarm control signal is output to the alarm module 10 to trigger an alarm. Simultaneously, the control module 8 transmits the collected data and the data comparison results to the display screen 4 for display. The control module 8 also stores the collected data in the storage module 12 and / or transmits the collected data to a remote control center via the IoT communication module 11, thereby enabling fire inspection of fire protection facilities and the target environment. During use, inspection personnel can adjust the length of the telescopic handheld pole 2 according to actual needs to meet data collection requirements at different heights and locations.
[0040] In one embodiment, the control module 8 employs an ARM Cortex-M7 series processor. This processor boasts powerful computing capabilities and multitasking abilities, enabling it to process various types of data and instructions quickly and accurately. As the core control unit of the entire device, the control module 8's main functions include: receiving instructions input via operation buttons 5, parsing and processing these instructions to control the operation of the detection module 9, the IoT communication module 11, and the storage module 12; processing and analyzing the data collected by the detection module 9 in real time, using preset algorithms and thresholds to determine if there are any abnormalities in the fire protection facilities and surrounding environment; displaying the processing results intuitively on the display screen 4 for easy viewing by inspection personnel; and coordinating the work between various modules of the device to ensure the stability and reliability of the equipment's operation.
[0041] In one embodiment, the temperature detection unit 901 employs an infrared temperature sensor. Specifically, the infrared temperature sensor can be a Lepton series infrared sensor from FLIR Systems, which features non-contact measurement, fast response, and high measurement accuracy. Its working principle involves detecting the infrared energy radiated from the surface of an object, converting it into an electrical signal, and then processing it through signal amplification, filtering, and analog-to-digital conversion to obtain the object's temperature data. The temperature detection unit 901 can achieve a wide temperature range measurement from -40℃ to 550℃, with a measurement accuracy of ±2℃ or ±2% of the reading (whichever is greater). It can quickly and accurately measure the temperature of fire-fighting facilities (such as electrical equipment and fire pipes) and the surrounding environment, promptly detecting fire hazards caused by overheating. Simultaneously, this unit also supports multi-point temperature detection and temperature imaging functions, generating a visual temperature distribution map to help inspection personnel understand the temperature distribution more intuitively.
[0042] In one embodiment, the smoke detection unit 902 employs a photoelectric smoke sensor. The photoelectric smoke sensor operates based on the principle of light scattering. Under normal circumstances, the infrared light emitted by the light-emitting diode is blocked by a light shield and cannot reach the photodetector. When smoke enters the detection chamber, smoke particles scatter the infrared light, causing some of it to reach the photodetector, thus generating an electrical signal. By processing and analyzing this electrical signal, the smoke concentration in the environment can be detected in real time. The photoelectric smoke sensor is highly sensitive, capable of detecting early signs of fire even when smoke concentration is extremely low, and issuing different levels of alarm signals based on the smoke concentration.
[0043] In one embodiment, the gas detection unit 903 employs an electrochemical gas sensor array. The electrochemical gas sensor array can simultaneously detect the concentrations of multiple combustible or harmful gases, such as carbon monoxide, hydrogen, hydrogen sulfide, and carbon dioxide. Within the electrochemical gas sensor array, different types of gas sensors exhibit high selectivity and high sensitivity for their respective gases, generating electrical signals through chemical reactions with the gases. The magnitude of these electrical signals is directly proportional to the gas concentration.
[0044] In one embodiment, the image acquisition unit 904 employs a high-definition camera. Specifically, the high-definition camera may use a Sony IMX586 image sensor, possessing a high-resolution shooting capability of 48 megapixels and supporting autofocus and optical image stabilization. The image acquisition unit 904 can not only capture information such as the appearance, installation location, and signage of fire-fighting facilities, but also record the overall environmental conditions of the inspection site. Simultaneously, this unit can integrate image recognition technology, automatically identifying whether fire-fighting facilities are damaged, missing, or improperly installed by comparing them with a built-in standard image database of fire-fighting facilities, and marking and recording any abnormalities. Furthermore, the image acquisition unit 904 can also support video recording, which can be used to record important events and details during the inspection process.
[0045] In one embodiment, the IoT communication module 11 includes a 4G / 5G communication unit 111 and a Wi-Fi communication unit 112, which are respectively connected to the control module 8.

[0047] In one embodiment, storage module 12 employs a high-capacity flash memory chip, such as Samsung's K90F1G08UOA-PB0 flash memory chip, with a storage capacity of up to 128GB. Storage module 12 is primarily used to store detection data, image information, device operation logs, system configuration information, etc. To improve data storage efficiency and security, storage module 12 can use the FAT32 file system for data management and encrypt important data to prevent data leakage and tampering. Simultaneously, storage module 12 also supports circular storage, automatically overwriting the oldest stored data when storage space is insufficient, ensuring the device can continuously record the latest inspection information. Furthermore, storage module 12 provides data backup and recovery functions, allowing stored data to be backed up to an external storage device via a USB interface for data recovery and analysis when needed.
[0048] In one embodiment, the power module 13 includes a rechargeable lithium battery 131 and a charging management circuit 132. The rechargeable lithium battery 131 is connected to the charging management circuit 132, which is connected to the charging interface 7. The rechargeable lithium battery 131 is connected to the control module 8 via a power switch 6. The rechargeable lithium battery 131 uses a high-energy-density lithium-ion battery, such as Panasonic's NCR18650PF lithium-ion battery, with a capacity of 5000mAh, capable of providing continuous power for more than 8 hours. The charging management circuit 132 uses Texas Instruments' BQ24195 charging management chip, which has multiple protection functions such as overcharge protection, over-discharge protection, overcurrent protection, and short-circuit protection to ensure the safety of the lithium battery during charging and use. The charging interface 7 uses a Type-C interface, supports the PD fast charging protocol, and has a charging power of up to 30W, which can fully charge the lithium battery in 2 hours. In addition, the power module 13 can also have a power monitoring function, which displays the remaining power of the lithium battery in real time through the display screen 4. When the power is lower than 20%, a low power alarm signal is issued to remind the inspection personnel to charge it in time.
[0049] In one embodiment, display screen 4 is a touchscreen, allowing inspection personnel to easily set equipment functions and query data via touch operation. Display screen 4 uses a 5.5-inch IPS LCD screen with a resolution of 1920×1080, featuring high brightness, high contrast, and wide viewing angles, ensuring clear image display even in bright sunlight. The touchscreen employs capacitive touch technology, supporting multi-touch, with fast response and smooth operation. Furthermore, display screen 4 also features automatic brightness adjustment, automatically adjusting screen brightness according to ambient light levels, ensuring both display quality and power efficiency.
[0050] In one embodiment, the shoulder strap 3 is made of high-strength nylon. The length of the shoulder strap 3 can be adjusted via an adjustment buckle 301, and the shoulder strap 3 is detachably connected to the housing 1 via a locking connection structure 302. The shoulder strap 3 allows the equipment to be carried on the body, facilitating transport and reducing the burden on inspection personnel. The shoulder strap 3, made of high-strength nylon, is wear-resistant and corrosion-resistant. The length of the shoulder strap 3 is adjustable via the adjustment buckle 301, making it suitable for inspection personnel of different statures. Furthermore, the quick-release connection method of the locking connection structure 302 between the shoulder strap 3 and the housing 1 allows for rapid installation and removal of the shoulder strap 3 according to actual needs, facilitating the switching of the equipment in different usage scenarios.
[0051] In one embodiment, the upper end of the telescopic hand rod 2 is detachably connected to the lower end of the housing 1 via a threaded connection. The lower end of the telescopic hand rod 2 is equipped with a non-slip grip 201. The telescopic structure of the telescopic hand rod 2 adopts a multi-stage sleeve structure, with an adjustment range of 20cm to 100cm.

Its telescopic structure uses a multi-stage sleeve design, and different lengths can be adjusted through a rotating lock, allowing for flexible adjustment according to usage needs. This facilitates operation by inspection personnel at different heights and positions. For example, when inspecting fire-fighting facilities at heights, the hand rod 2 can be extended, avoiding the use of ladders or other auxiliary tools, thus improving the convenience and safety of inspections. The surface of the non-slip grip 201 is made of rubber with a non-slip texture design, increasing friction during gripping and preventing the equipment from slipping during use.
[0052] The workflow of this portable, multifunctional smart fire inspection device based on the Internet of Things is as follows:
[0053] 1. Power-on preparation
