Live line proximity monitoring alarm device based on MEMS electric field sensor

Abstract

The invention discloses a live line proximity monitoring alarm device based on a MEMS electric field sensor. A MEMS electric field sensor probe detects an electric field. A central processor drives an alarm device to give an alarm according to electric field data. The monitoring alarm device uses the MEMS electric field sensor probe, achieves low power consumption, a small size and high spatial resolution, can simultaneously measure a DC electric field and an AC electric field, can be used for a DC live line and a power-frequency live line, and has obvious application advantages over a conventional early-warning equipment. The monitoring alarm device uses positioning technology and far and near distance wireless transmission technology, can wirelessly send alarm data and location information to a local monitoring device and a remote data center simultaneously, achieve multi-level monitoring, ensure the construction safety of large mechanical equipment such as cranes, construction vehicles and workers, and avoids accidents.

Description

technical field [0001] The invention relates to a monitoring and alarming device for an adjacent live line, in particular to a monitoring and alarming device for an adjacent live line based on a MEMS electric field sensor. Background technique [0002] According to incomplete statistics, there are at least more than 100 accidents where high-altitude cranes touch high-voltage lines in my country every year. Once an accident occurs, the losses are often very heavy, and it is easy to cause equipment damage, casualties, and large-scale power outages. With more and more electrical equipment and more complex construction environments, the danger points of construction sites under high-voltage lines have also become diversified, such as unsafe working environments on construction sites, operating behaviors that violate safety regulations, and construction The increase in personnel and equipment leads to an increase in the workload and technical complexity of manual operations, whic...

[0002] According to incomplete statistics, there are at least more than 100 accidents where high-altitude cranes touch high-voltage lines in my country every year. Once an accident occurs, the losses are often very heavy, and it is easy to cause equipment damage, casualties, and large-scale power outages.

With more and more electrical equipment and more complex construction environments, the danger points of construction sites under high-voltage lines have also become diversified, such as unsafe working environments on construction sites, operating behaviors that violate safety regulations, and construction The increase in personnel and equipment leads to an increase in the workload and technical complexity of manual operations, which not only increases labor intensity but also causes many unsafe factors and increases the possibility of accidents.

Accidents will not only cause huge economic losses, but also cause a large number of casualties
