Wireless monitoring device for passive environmental parameters

Abstract

The invention discloses a wireless monitoring device for passive environmental parameters, and aims to provide a wireless monitoring device for passive environmental parameters, which has stable work and long service life and can transmit electric energy through radio. The wireless monitoring device comprises a high-frequency wireless environmental parameter on-line monitoring device (1) and an RF electric energy transmitting and main feed transmitting device (2), wherein the high-frequency wireless environmental parameter on-line monitoring device (1) comprises an RF power receiver (11), a power supply recovery module (12) and a voltage stabilizing and energy storing module (13); the RF electric energy transmitting and main feed transmitting device (2) is connected with the RF power receiver (11) through electromagnetic wave induction; the RF power receiver (11) is electrically connected with the power supply recovery module (12) which is electrically connected with the voltage stabilizing and energy storing module (13); and the voltage stabilizing and energy storing module (13) outputs working power to the high-frequency wireless environmental parameter on-line monitoring device (1). The wireless monitoring device can be widely applied to the field of environmental parameter on-line monitoring and early warning.

Description

technical field [0001] The invention relates to a passive environmental parameter wireless monitoring device. Background technique [0002] With the development of technology and the continuous improvement of automation, more and more equipment adopts real-time monitoring of various environmental parameters to ensure the reliability of operation. Power system distribution transformers and switch contacts, busbars or cable connections of distribution lines can judge and predict the operating status by monitoring their surface heating in real time, and prompt hidden troubles; Accident precursors can be prevented through online monitoring of scientific key parameters, and the cost is reasonable. [0003] The above-mentioned various monitoring devices need to be installed in different locations and parts, and wireless connection between each other is an inevitable requirement when forming a monitoring system. With the increasingly low power consumption of electronic devices an...

Problems solved by technology

With the increasingly low power consumption of electronic devices and the development of battery technology, built-in batteries become possible, but after all, the battery power supply has a short service life and is difficult to meet the requirements of use due to its large size; Solar power supply also has the defects of large size and high cost, and the instability of solar energy utilization due to the influence of weather and installation location, which limits the use of solar energy in power supply and cannot meet the requirements for stable power supply.

[0004] In summary, the existing technology has technical defects such as short life, unstable use, and large limitations.
