Problems solved by technology

Due to the particularity of forest fire monitoring, the wireless sensor network needs to deploy and control a large number of nodes, and each node needs to be equipped with an independent power supply module. However, the existing battery system often has self-discharge phenomenon, and its service life is limited. It takes a lot of manpower and material resources to replace the battery of the monitoring node

Abstract

The invention discloses a fire-responsive temperature-controlled battery, a preparation method and application thereof, and belongs to the technical field of fire monitoring. The temperature-controlled battery of the present invention includes an electrode and an electrolyte, and a phase change protection layer is arranged between the electrode and the electrolyte to isolate the contact between the electrolyte and the electrode. The temperature-controlled battery of the present invention has no electric energy output in a natural environment, but in a high-temperature environment, the phase change material changes to make the battery work and output electric energy, so that the temperature can control the power output of the battery. The temperature-controlled battery is low in cost, suitable for large-area control in a natural environment, and can effectively increase the placement density of fire monitoring nodes.

Description

technical field [0001] The invention relates to the technical field of fire monitoring, in particular to a fire-responsive temperature-controlled battery and its preparation method and application. Background technique [0002] Forest fires are sudden, destructive, and difficult to deal with and rescue, which seriously threaten the safety of soil, vegetation, water bodies and even human life and property. For forest fire prevention, various countries have developed different forest fire monitoring systems. Germany adopts the FIRE-WATCH forest fire automatic early warning system. China mainly relies on satellite remote sensing, aircraft cruising, and ground watchtower patrols to monitor forest fires. Although the above methods have certain advantages in terms of detection range and data collection, the accuracy of detection needs to be improved, and it still seems powerless in terms of early warning of fires. [0003] In recent years, fire warning systems based on wireless ...
