Description
Technical Field
The invention relates to the technical field of power equipment positioning, in particular to a power equipment positioning system based on wireless communication.
Background
In the field of electric power, electric power equipment such as substations, metering devices, power distribution cabinets and the like are often distributed in locations which are not accessible, including basements, astronomy, corridor and the like, on the one hand for security reasons to prevent unauthorized access and damage and on the other hand also for protecting the equipment to reduce the risk of theft or destruction of the equipment. Accurate positioning and effective management of these devices is critical to the safety, reliability and efficiency of the power supply. However, conventional device management systems often face a number of challenges in these environments, such as device loss, inaccurate positioning, difficult maintenance, and the like. In the conventional process of searching the installation position of the field device, the installation position is often determined by the personal experience of a manager in a platform region and the working life of the manager in the district, and the field target device cannot be rapidly arrived at the field.
Reasons why power field location is often faced with location signal problems include:
1. signal blocking: the walls and floors of basements are typically constructed of concrete, masonry, and the like materials that significantly block conventional positioning signals, such as GPS signals, bluetooth signals, or Wi-Fi signals. This can result in a signal being not received in the basement that is strong enough to be accurately located.
2. Multipath propagation: basement environments are prone to multipath propagation problems, i.e., reflection and diffraction of signals between walls and objects, creating multiple paths of arrival. This complicates the arrival time and intensity of the signal and makes accurate measurement difficult.
3. Signal interference: basements often have a large number of power lines, electronics, plumbing, and metal structures that can create wireless signal interference, degrading the quality of the positioning signals.
4. Limited antenna height: the ceiling height of the basement is typically limited, which reduces the location of the receiving antennas and thus the chances of receiving signals.
5. Underground depth: the deeper the basement is, the further from the ground the distance the signal travels can be limited, which can reduce the accuracy of the positioning.
6. Limited signal coverage: the basements often lack external signal coverage, such as GPS signals or wireless network signals, which makes it more difficult to receive the signals.
