Description

Technical Field

[0001] This utility model belongs to the field of gas metering technology, specifically relating to a gas meter that can be charged using a wireless charging bank. Background Technology

[0002] Traditional smart gas meters suffer from significant power supply and user experience issues. First, when powered by external dry-cell batteries, the continuous operation of the meter's communication, metering, and safety control modules consumes a large amount of power, resulting in short battery life and requiring frequent battery replacements—a cumbersome and costly process. Second, while disposable lithium batteries extend power supply time, maintenance and replacement costs are high, and power outages pose a risk, potentially disrupting gas usage or even causing safety hazards. Furthermore, traditional gas meters lack intelligent features, failing to monitor battery status in real time or integrate with smart home systems, leading to a poor user experience. Additionally, battery performance is unstable in extreme environments, further reducing reliability. These problems increase the financial burden on users and management departments, necessitating a more efficient and convenient power supply solution. Utility Model Content

[0021] 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.

[0022] The present invention will be further described in detail below with reference to the embodiments.

[0023] like Figure 1 and Figure 2 As shown, a specific embodiment of the gas meter that can be charged using a wireless charging bank provided by this utility model is as follows:

[0024] A gas meter that can be charged using a wireless charging bank includes the following modules:

[0025] Gas metering module 1 is used to detect and record gas consumption in real time;

[0026] Communication module 2 is used for data transmission and smart home integration; communication module 2 includes NB-IoT module 3 and Bluetooth Mesh module 4. NB-IoT module 3 supports remote data transmission and is particularly suitable for Internet of Things (IoT) devices. NB-IoT module 3 has a power consumption of less than 5mW, resulting in low energy consumption and extending the device's lifespan. Bluetooth Mesh module 4 supports local smart home integration.

[0027] Safety control module 5 is used for remotely shutting off the gas passage. Module 5 includes a solenoid valve 6 and a valve actuator chip 7. The solenoid valve 6 can be a two-stage design. The first stage is rapid shut-off: the design focus at this stage is speed, with a response time of less than 0.5 seconds. Rapid shut-off is crucial for immediate response to emergencies, stopping gas flow in the shortest possible time and reducing risk. The second stage is complete sealing: in addition to rapid response, it is necessary to ensure system safety by completely sealing the gas passage. This step ensures that even in an emergency, gas will not continue to leak, providing additional safety.

[0028] Main control module 8 is used to control the operating status of the gas meter; main control module 8 is an STM32L4 series microcontroller;

[0029] The power module 9 is used to provide power to the gas metering module 1, the communication module 2, the safety control module 5 and the main control module 8; the power module 9 includes a lithium battery 10, a temperature sensor 11 and a power management chip 12, and the temperature sensor 11 monitors the battery temperature in real time.

[0030] The wireless charging module 13 is used to wirelessly charge the power module 9 and monitor battery safety during charging. The wireless charging module 13 is existing technology and mainly includes a transmitter (primary coil), a receiver (secondary coil), and a charging management chip 14. The wireless charging module 13 relies on the electromagnetic field between the transmitter and receiver to transmit energy. The transmitter supports fast charging protocols PD 2.0, PD 3.0, QC 2.0, QC 3.0, and QC 4.0, with an adjustable charging power range of 1-5W. This not only significantly shortens charging time but also ensures the safety and efficiency of the entire charging process. For users, this design greatly improves device compatibility, eliminating concerns about charging compatibility between different brands of devices.

[0031] The main control module 8 is connected to the gas metering module 1, the communication module 2, the safety control module 5, the power supply module 9, and the wireless charging module 13, respectively.

[0032] The wireless charging process is as follows: When the lithium battery 10's charge level is below 20%, the main control module 8 sends a low-battery alarm signal to the smart home system through the communication module 2 and starts charging. After the transmitter of the wireless charging module 13 is powered on, it charges the lithium battery 10 through electromagnetic coupling. When the lithium battery 10's charge level is above 95%, the main control module 8 sends a fully charged signal. If the temperature sensor 11 detects that the lithium battery 10's temperature is above 60°C during charging, charging will stop, and the main control module 8 will send a high-temperature alarm signal for the battery.
