[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Reference Figures 1-3 A long-lasting wireless four-in-one gas detector alarm includes a main unit 1 and a magnetic battery compartment 2, wherein:

[0037] The magnetic electromagnetic chamber 2 is equipped with a strobe light 8; the main unit 1 is equipped with a gas sensor 3, a voice alarm, a LORA wireless communication module and a built-in power supply; the gas sensor 3 is used to collect the gas concentration;

[0038] During operation, the back of the magnetic battery compartment 2 is attached to the metal structure in the room to be monitored. The magnetic battery compartment 2 serves as an external power source to charge the main unit. The back of the main unit 1 is connected to the front of the magnetic battery compartment 2 via a signal line. When the main unit 1 detects that the concentration of any gas collected by the gas sensor 3 exceeds the preset safety range, the voice alarm sounds, the strobe light 8 flashes, and the LORA wireless communication module transmits data, including the collected gas concentration, to the monitoring terminal.

[0039] Specifically, the signal line uses signal metal pins. During operation, the back of the main unit 1 and the front of the magnetic battery compartment 2 are connected via signal metal pins to achieve signal transmission between the main unit 1 and the magnetic battery compartment 2, enabling the strobe light 8 to accurately alarm. Additionally, the back of the main unit 1 and the front of the magnetic battery compartment 2 are connected via two charging metal pins to enable the magnetic charging compartment 2 to charge the main unit 1. These charging metal pins can be gold-plated copper. Furthermore, the magnetic battery compartment 2 has a support 10 at its bottom, making it L-shaped, with the bottom of the main unit 1 supported by the support 10. The main unit 1 also includes an antenna 7 for signal transmission, a power switch knob 6, and a display screen 4 for displaying data including the remaining battery level in the magnetic battery compartment 2, signal strength, and gas concentration. The side of the main unit 1 also has operation buttons 12. The magnetic battery compartment 2 also has a battery level indicator light 9 to indicate its battery level. In addition, a channel knob 11 is located next to the power switch knob 6 on the main unit 1 for channel selection. The channel knob 11 can select the channel, which can avoid transmission redundancy caused by connecting too many long-lasting wireless four-in-one gas detectors to one gateway.

[0040] In this embodiment, the strobe light 8 is located on the front of the support 10, the voice alarm outlet 5 is located on the upper front of the main unit 1, multiple gas sensors 3 are located on the lower front of the main unit 1, and the display screen 4 is located between the voice alarm outlet 5 and the gas sensors 3. The strobe light 8 is installed at the bottom of the battery compartment 2, and the voice alarm is installed on the upper part of the main unit, ensuring that the alarm signal is conspicuous and easily detected. In noisy working environments, the voice alarm may be too quiet to be heard; adding the strobe light 8 provides an additional way for workers in confined spaces to detect hazards. The display screen 4 is located on the front of the main unit 1, allowing users to easily view various information. The magnetic battery compartment 2 is located on the back of the main unit 1. When the battery needs to be replaced, the magnetic battery compartment 2 can be detached from the main unit 1 for battery replacement. After the battery is replaced, the magnetic battery compartment 2 is plugged back into the main unit 1 to continue supplying power. The magnetic battery compartment 2 is plugged into the main unit 1. The support 10 at the bottom of the magnetic battery compartment 2 also supports the main unit 1. Therefore, the magnetic battery compartment 2 not only serves to supplement the alarm with the flashing light 8 and charge the main unit 1, but also acts as the installation structure of the main unit 1, enabling the detection alarm to be quickly installed in the monitoring room without the need for other additional installation devices.

[0041] For example, the room to be monitored can be a ship's cabin, and the metal structure can be the bulkhead of the ship's cabin. The number of gas sensors 3 is at least three, and the gases include oxygen, carbon monoxide, and hydrogen sulfide; the magnetic battery compartment 2 is equipped with a polymer lithium battery; the monitoring terminal is a remote monitoring platform and / or a mobile phone.

[0042] More specifically, four gas sensors 3 are installed on the main unit 1, enabling real-time monitoring of the concentrations of combustible gases such as oxygen, carbon monoxide, and hydrogen sulfide (oxygen is the default flammable gas). This ensures accurate measurement of each gas concentration. An alarm is triggered if the concentration of any gas exceeds the preset safety range. The gas sensors 3, equipped with high sensitivity and rapid response characteristics, can capture changes in gas concentration in real time, achieving comprehensive and accurate monitoring of multiple hazardous gases. This provides accurate data for subsequent alarms and data transmission, effectively preventing safety accidents caused by gas leaks. When this long-lasting wireless four-in-one gas detector and alarm detects a gas concentration exceeding the preset safety range, it quickly triggers a high-brightness flashing light alarm and a clear voice alarm. Simultaneously, through the built-in LoRa wireless communication module, it uploads alarm information and real-time gas concentration data to a remote monitoring platform. It also supports dual protection of local and remote alarm functions, ensuring timely transmission of danger information to on-site and remote personnel, improving the timeliness and reliability of alarms, enabling remote monitoring and management, and allowing relevant personnel to quickly respond to emergencies and take timely measures to eliminate dangers and reduce accident losses.

[0043] The magnetic battery compartment 2 houses a high-capacity polymer lithium battery, optimizes the power management system, reduces power consumption, and enables ultra-long battery life. After the main unit 1 is separated from the magnetic battery compartment 2, the main unit 1 can operate independently. The built-in power supply of the main unit 1 can support continuous operation for more than 24 hours. When the main unit 1 is connected to the magnetic battery compartment 2, the battery life is extended to more than 10 days (10*24h). Compared with traditional main units without a power bank, this significantly reduces the maintenance frequency of the main unit 1 requiring charging or replacing the built-in power supply, providing the main unit 1 with long-lasting and stable power support, ensuring continuous normal operation during long-term use, reducing downtime due to power issues, and improving the efficiency of the main unit 1.

[0044] The main unit 1 is equipped with a simple and easy-to-use display screen 4. Users can operate the main unit 1 with one-button operation via the button 12 on its side to view gas concentration parameters, signal strength data, and other functions displayed on the display screen 4. It is worth noting that the one-button operation of the main unit 1 means that multiple functions can be achieved through one button 12, but it does not mean that only one button 12 can be set on the side of the main unit 1. Where possible, other buttons 12 can be set on the side of the main unit 1 to achieve other functions. The main unit 1 supports LoRa wireless networking, and can build monitoring networks with various topologies such as star, tree, or mesh according to actual needs, realizing interconnection and interoperability between multiple main units 1, and meeting the deployment requirements of different scales and complex environments. The one-button operation of the button 12 on the side of the main unit 1 reduces the difficulty of operation, improves the ease of use and operability of this long-endurance wireless four-in-one gas detector and alarm, and facilitates quick use by field personnel. The flexible networking function enhances the scalability and adaptability of this long-endurance wireless four-in-one gas detector and alarm, enabling comprehensive gas monitoring coverage of large areas or complex spaces.

[0045] The following example illustrates the operation of this long-lasting wireless four-in-one gas detector and alarm:

[0046] During ship repair operations at the shipyard, workers magnetically attach this long-endurance wireless four-in-one gas detector and alarm to the ship's bulkhead in confined spaces. The alarm monitors the concentrations of oxygen, carbon monoxide, hydrogen sulfide, and other combustible gases in real time and with high accuracy. During welding operations, if hydrogen sulfide levels exceed the limit, the alarm is immediately triggered, the strobe light 8 flashes a bright red light, and the voice alarm emits a loud "Hydrogen sulfide concentration exceeds the upper limit!" Simultaneously, the alarm information and real-time concentration data are uploaded to the remote monitoring platform of safety personnel and notified to safety management personnel via a mobile app within seconds through the LoRa wireless communication module. Personnel monitoring confined spaces on the ship can promptly obtain information about the gas conditions inside the cabin via the mobile app and quickly implement emergency measures such as ventilation and personnel evacuation to prevent potential accidents. The magnetic battery compartment design extends the operating range and makes battery replacement more convenient, allowing for more than 10 days of continuous operation on a single charge, meeting the needs of long-term ship repair and maintenance operations.

[0047] It should be noted that the functions of the host 1 in this embodiment, such as triggering the voice alarm and flashing light 8 when the gas concentration exceeds the preset safety range, remote data transmission, one-button operation, and wireless networking, can all be implemented by existing technologies, and there is no problem of insufficient disclosure. This embodiment integrates these functions into the long-lasting wireless four-in-one gas detector alarm, and creatively designs the composition of the long-lasting wireless four-in-one gas detector alarm (including the host 1 and the magnetic battery compartment 2), the structure of the host 1, the structure of the magnetic battery compartment 2, the connection relationship between the host 1 and the magnetic battery compartment 2, and the selection of various function implementation methods.

[0048] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
