Description

Technical Field

[0001] The invention relates to a combustible moisture content detection technology, and in particular to a portable combustible moisture content, load collaborative determination electronic balance and a determination method, and belongs to the field of forest fire prevention. Background Art

[0002] In forest fire prevention work, field investigation is an extremely critical link, and it plays an indispensable role in assessing forest fire risks and formulating fire prevention strategies. Among them, the determination of the moisture content of combustible materials in the field is particularly important because it is directly related to the probability of forest fires and the characteristics of fire spread. However, existing measurement methods often make it difficult to quickly obtain moisture content data of combustible materials in the field. In the complex and changeable environment of the field, efficient and convenient measurement methods are needed, but traditional technologies have obvious deficiencies in this regard, which greatly reduces the timeliness of data acquisition and cannot provide strong support for forest fire prevention decisions in a timely manner.

[0003] As a common measuring tool, the design and function of ordinary balances are mainly focused on laboratory environments. In the field, not only are the operating environment requirements harsh, but also they lack the characteristics to adapt to complex factors such as field terrain and climate, making it difficult to carry out experiments smoothly. This greatly limits the possibility of accurately measuring the mass of combustibles in the field, and thus affects the accuracy and feasibility of moisture content determination.

[0004] Field surveys for forest fire prevention often require frequent movement between different areas. Conventional measurement devices are large in size and complex in structure, making them extremely inconvenient to transport and carry. This not only increases the workload of investigators, but may also result in some areas being unable to conduct surveys and data collection in a timely manner due to the difficulty in smoothly transferring the devices, affecting the comprehensiveness and efficiency of the entire forest fire prevention field survey.

[0005] In summary, it is urgent to design a device that can overcome the above problems and is suitable for forest fire prevention field investigations to improve the quality and efficiency of forest fire prevention work. Summary of the invention
