Description

Technical Field

[0001] This utility model belongs to the field of gas safety technology, specifically a gas safety intelligent detection device. Background Technology

[0002] Gas is widely used in daily life and production, but gas leaks, aging pipelines, and loose connections can easily lead to safety accidents. Therefore, the reliability and practicality of gas safety detection devices are crucial. Existing detection devices have the following shortcomings in circuit structure and functional implementation:

[0003] First, the circuit integration is low, resulting in poor deployment adaptability. Existing devices mostly adopt a discrete module design, with functional modules such as image acquisition, gas data acquisition, and data transmission operating independently. This requires complex external wiring connections, leading to a large overall size and making it difficult to adapt to different installation scenarios such as small kitchens or integrated gas appliances, resulting in poor compatibility.

[0004] Secondly, insufficient stability of the power supply circuit affects operational reliability. Some devices lack dedicated voltage regulator modules, and external voltage fluctuations can easily lead to data loss in the image acquisition module or distortion of sensor signals. At the same time, the lack of power supply protection circuits such as overcurrent and reverse connection protection makes the core module susceptible to damage and shortens its service life when the power supply is abnormal.

[0005] Furthermore, the data acquisition and transmission circuits have poor compatibility, limiting the detection dimensions. Existing devices have inconsistent interfaces, making it difficult to adapt to various gas meter models and obtain stable data such as gas pressure and flow; moreover, most only support a single type of data acquisition and do not reserve an image acquisition interface, making it difficult to cover physical hazards such as pipeline aging.

[0006] Furthermore, the storage and processing modules have poor coordination and limited functionality. Communication between the storage and processing modules is inefficient, with insufficient capacity and slow read speeds, making it unable to support the identification of multiple types of hazards. The processing module cannot process image and gas data simultaneously, limiting comprehensive detection capabilities.

[0007] Finally, the lack of power consumption control circuitry results in high operating costs. The data transmission module lacks a low-power design, leading to high energy consumption and expenses due to continuous operation. Furthermore, the absence of periodic power supply control prevents the module from being started and stopped on demand, further exacerbating the energy consumption problem. In addition, the circuit lacks scalability; adding new detection functions requires redesigning the circuit, making upgrades difficult.

[0008] In view of the deficiencies in the circuit structure and function implementation of the existing technology, there is an urgent need for a gas safety intelligent detection device with high circuit integration, stable power supply, strong compatibility, low power consumption and good scalability, so as to solve the problems of difficult deployment, low reliability and limited detection dimensions of the existing devices.
