Embodiment 1

[0039] A non-contact transmission line galloping monitoring device, such as figure 1 As shown, it includes: a power supply unit, and a processor, a dancing monitoring unit, a reed switch and a communication unit connected with the power supply unit;

[0040] The processor is respectively connected with the dancing monitoring unit, the reed switch and the communication unit;

[0041] The reed switch is used to generate a magnetic field signal when subjected to a magnetic field force, and transmit the magnetic field signal to the processor;

[0042] The processor is configured to, based on the duration of the magnetic field signal, determine whether to wake up the dance monitoring unit to enter the sniffing mode;

[0043] The dancing monitoring unit is used to actively request to connect to the gateway after entering the sniffing mode, and when connecting to the gateway, switch from the sniffing mode to the online mode to monitor the dancing situation of the monitored node;

...

Embodiment 2

[0059] The present invention based on the same inventive concept also provides a method for starting the non-contact transmission line galloping monitoring device, such as figure 2 shown, including:

[0060] Step 1: The processor determines whether to wake up the dance monitoring unit to enter the sniffing mode based on the magnetic field signal transmitted by the reed switch when it is subjected to the magnetic force;

[0061] Step 2: After the dancing monitoring unit enters the sniffing mode, it actively requests to connect to the gateway, and when connected to the gateway, the dancing monitoring unit is switched from the sniffing mode to the online mode to monitor the dancing of the monitored node;

[0062] Step 3: The communication unit uploads the galloping situation of the monitored node monitored by the galloping monitoring unit to the base station.

[0063] Step 1: The processor determines whether to wake up the dance monitoring unit to enter the sniffing mode based ...

Embodiment 3

[0075] A method for starting a non-contact transmission line galloping monitoring device, such as image 3 shown:

[0076] The dancing monitoring device is installed on the node to be monitored on the transmission line, and transmits the monitoring situation to the base station. Before the actual operation, there is an automatic network connection process. The design implementation method is as follows:

[0077] 1) After the node system software is powered on and initialized, it enters the sniffing mode. By default, it sniffs every 5 minutes. If it is not connected to the gateway, continue sniffing -> sleep -> sniffing cycle.

[0078] 2) Once the dance monitoring device is connected to the base station, the sleep interval can be configured by the base station;

[0079] 3) Since the base station equipment has built-in large batteries and solar panels, there is no need to worry about the power, and the base station can be considered to be always online and will not sleep. In...

Abstract

The invention provides a non-contact power transmission line galloping monitoring device and a starting method. The non-contact power transmission line galloping monitoring device comprises a power supply unit, and a processor, a galloping monitoring unit, a reed switch and a communication unit which are connected with the power supply unit, the processor is respectively connected with the galloping monitoring unit, the reed switch and the communication unit; the reed switch is used for generating a magnetic field signal when being subjected to a magnetic field force and transmitting the magnetic field signal to the processor; the processor is used for determining whether to wake up the galloping monitoring unit to enter a sniffing mode based on the duration of the magnetic field signal; the galloping monitoring unit is used for actively requesting to connect with a gateway after entering the sniffing mode, and switching from the sniffing mode to the online mode to monitor the galloping condition of the monitored node when the galloping monitoring unit is connected with the gateway; the communication unit is used for uploading the galloping condition of the monitored node monitored by the galloping monitoring unit to the base station; according to the invention, false triggering caused by an external accidental magnetic field is reduced, and placement and triggering of the switch can be completed on the premise of not damaging an equipment shell.

Description

technical field [0001] The invention relates to the field of transmission lines, in particular to a non-contact transmission line galloping monitoring device and a starting method. Background technique [0002] With the rapid development of my country's economy, the demand for electric energy and the requirements for electric power quality are also constantly increasing, and electric energy has become a necessity for social existence and development. However, due to the influence of various factors, power grid accidents still exist in some areas of our country. Power grid accidents not only have great impact, fast speed, and serious consequences, but also directly affect the country's production and construction and people's living order. Conductor galloping is a common phenomenon in power transmission and distribution lines. It has a wide range. It will occur at all voltage levels as long as the conditions are met, and the impact and damage on power lines are more serious. ...
