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

Embodiment 1

[0052] (1) The raw materials used in the fire-responsive temperature-controlled battery in this embodiment are as follows:

[0053] Positive electrode material: graphite electrode

[0054] Electrolyte material: copper chloride pentahydrate

[0055]Electrolyte tank material: polymethyl methacrylate

[0056] Phase change protective layer: 60# paraffin

[0057] Negative electrode material: iron electrode

[0058] (2) The preparation steps are as follows:

[0059] 1) Copper chloride pentahydrate is packed into the electrolytic cell.

[0060] 2) Apply 60# paraffin wax to the surface of the iron electrode to prepare a 0.1 mm thick phase change protective layer to isolate the contact between the electrolyte material and the electrode material.

[0061] 3) Iron electrodes and graphite electrodes are respectively attached to both sides of the electrolytic cell to form a battery structure and packaged.

Embodiment 2

[0063] (1) The difference between this embodiment and Embodiment 1 is that the electrolyte materials used are different. In this embodiment, the raw materials used in the fire-responsive temperature-controlled battery are composed of the following:

Abstract

The invention discloses a fire response temperature control battery as well as a preparation method and application thereof, and belongs to the technical field of fire monitoring. The temperature control battery comprises an electrode and an electrolyte; a phase change protection layer is arranged between the electrode and the electrolyte to isolate the electrolyte from being in contact with the electrode. According to the temperature control battery, no electric energy is output in the natural environment, and the phase change material changes in the high-temperature environment, so that thebattery works to output electric energy, and the control of the temperature on the power output of the battery can be realized. The temperature control battery is low in cost, is suitable for large-area deployment and control in a natural environment, and can effectively improve 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 ...
