The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art in a specific case.
Embodiments of the present disclosure provide a monitoring device, such as a monitoring device that monitors power transmission conductor galloping. Referring to fig. 1, a monitoring device for monitoring galloping of a power transmission conductor includes, for example, a circuit module, a magnetic loop module, and a power supply module. The circuit module receives satellite signals in real time and outputs three-dimensional real-time coordinates of the monitoring equipment in real time; the magnetic ring module is sleeved on the power transmission wire and resists electromagnetic interference around the power transmission wire so as to ensure that the circuit module works normally; the power supply module is connected with the power supply end of the circuit module and the power supply end of the magnetic ring module, and the power supply module supplies power to the circuit module and the magnetic ring module.
At present, most research institutions monitor wire waving by adopting a sensor technology, and the sensor technology has the defects that a pull distance sensor is limited by an installation mode on one hand and limited by a measurement range on the other hand, and an acceleration sensor can measure frequency very well and measure amplitude very weak. It is therefore necessary to develop a rational, economical and effective monitoring means.
The embodiment of the invention monitors the galloping phenomenon of the transmission conductor by means of the current satellite navigation technology, and knows the conditions, mechanisms, characteristics and the like generated by the galloping of the transmission conductor, thereby providing basic data for solving the problem of galloping in the future.
The galloping monitoring equipment based on the satellite navigation technology can receive satellite signals in real time, can receive differential correction data from an electric satellite accurate service network, can output three-dimensional real-time coordinates of the galloping monitoring equipment in real time through internal resolving of the equipment, and sends resolving results to a monitoring platform in real time through a circuit module for data analysis and monitoring alarm.
According to the embodiment of the invention, the magnetic ring module is arranged on the power transmission wire, and because the wire galloping monitoring equipment is arranged on the high-voltage power transmission wire, the high-voltage power transmission wire can generate a very strong magnetic field environment and an inductance environment in the power transmission process. The monitoring device must be able to function well in high electromagnetic environments. Therefore, the monitoring device of the present embodiment has high electromagnetic compatibility requirements. Working in a strong electromagnetic environment generally has two effects, namely, the influence on satellite navigation signals, and monitoring equipment must be in a high-field-intensity environment to ensure stable receiving and resolving of satellite signals; secondly, the influence on the receiver is that the receiver cannot influence an internal circuit due to electromagnetic environment, so that system noise cannot work normally even.
