Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a signal enhancer control method and system for power distribution automation terminal equipment. Background Art

[0002] As an important part of the modernization of the power system, the distribution network automation system plays a key role in improving power supply reliability, optimizing grid operation efficiency and reducing operation and maintenance costs. However, with the continuous expansion of the scale of distribution networks and the increase in complexity, the existing distribution network automation system has exposed many shortcomings in practical applications. First, the traditional distribution network automation system generally has the problems of incomplete information collection and poor real-time performance. Due to the wide coverage of the distribution network and the scattered nodes, the traditional wired communication method is difficult to achieve comprehensive coverage, resulting in the inability to obtain and transmit some important data in a timely manner. Secondly, the reliability and stability of the system need to be improved. Under severe weather or natural disaster conditions, wired communication lines are easily damaged, causing system paralysis or communication interruption. In addition, the existing distribution network automation system also faces problems in communication technology. Challenges: Although wireless public network communication has been widely adopted due to its wide coverage, mature technology and convenient implementation, there are still many problems. First, the initial construction of wireless public network communication base stations mainly considered traditional call traffic, resulting in insufficient signal coverage in some areas, especially remote areas or underground power rooms. This makes the terminal equipment in the distribution automation system, especially the switchgear terminal equipment DTU, often offline due to weak signal strength or no signal, seriously affecting the normal operation and data collection of the system. Secondly, the transmission quality of wireless signals is easily affected by environmental factors, such as building obstruction or electromagnetic interference, resulting in unstable communication, delayed or lost data transmission. Furthermore, the performance limitations of existing wireless communication technologies in terms of bandwidth and latency make it difficult to meet the future distribution network's needs for real-time transmission and processing of big data.

[0003] In order to solve the problem of insufficient wireless signal strength, the construction and operation and maintenance of power grid automation terminal equipment currently usually adopt the method of extending the passive antenna or increasing the active antenna gain, but both have many disadvantages; on the one hand, although extending the passive antenna can enhance the signal to a certain extent, as the antenna length increases, the signal attenuation will become very serious and the effect is limited; on the other hand, although increasing the active antenna gain can improve the receiving sensitivity, it will also increase the power consumption and cost of the system. Therefore, these two methods cannot effectively solve the problem of signal coverage blind spots, and are still powerless for underground power rooms or areas with extremely weak signals.

[0046] Specifically, the first wireless signal data is processed based on the signal amplification control driving module, including the following steps: using a UDP request unit to send a connection request to a WIFI router in the processor module.

[0047] Based on the connection request, the UDP receiving unit is used to obtain the IP address returned by the WIFI router after allowing the connection.

[0048] The signal enhancement unit and the UDP receiving unit are connected. When the UDP receiving unit obtains the returned IP address, the mode of the signal amplification control driving module is judged. If the signal amplification control driving module is in the enhancement mode, the signal enhancement processing of the wireless LAN in the range of 40dbm to 85dbm is performed based on the returned IP address to obtain a preliminary amplified wireless signal.

[0054] dB=10lg(PsPn)

[0055] Wherein, dB is the signal-to-noise ratio of the initially amplified wireless signal; lg is the signal strength; Ps is the effective power of the initially amplified wireless signal; and Pn is the effective power of the noise.

[0056] Based on the signal-to-noise ratio of the preliminarily amplified wireless signal, the preliminarily amplified wireless signal is compensated by a signal compensation unit to obtain a compensated preliminarily amplified wireless signal.

[0071] Preferably, by utilizing the alarm module to actively monitor the connection stability of signal reception, rather than passively responding to system failures, potential communication risks can be discovered and handled in a timely manner before the problem expands, thereby improving the early detection rate of system anomalies and reducing the risk of system failures caused by communication interruptions. At the same time, timely detection of system anomalies can also enhance the maintainability and reliability of the system.
