| 摘 要： | 230 MHz电力无线专网的干扰种类主要有宽带全频干扰、窄带同频干扰和窄带邻频干扰3种。其中,宽带全频干扰主要是由各种LED电子屏、电子广告牌、电子铭牌以及射灯或照明灯引起;窄带同频干扰主要来自230 MHz频段内的非法电台和大功率雷达;窄带邻频干扰主要来自于其他使用230 MHz电力无线专网相邻频点的窄带通信系统。文章针对以上3种干扰类型,结合现网实际对230 MHz电力无线专网提出了相应的规避干扰解决思路,并就具体措施方法进行了详细介绍,以使230 MHz电力无线专网在实际应用中取得更高效能。

| Abstract: | The main types of interference in 230 MHz power wireless private network are broadband full-frequency interference,narrowband co-frequency interference and narrowband adjacent-frequency interference.Among them,wide-band full-frequency interference is mainly caused by various LED electronic screens,electronic billboards,electronic nameplates and spotlights or lighting lamps;narrowband co-frequency interference mainly comes from illegal radio and high-power radar in 230 MHz band;narrow-band adjacent-frequency interference mainly comes from other narrow-band passes using adjacent frequency points of 230 MHz power wireless private network.According to the above three types of interference,combined with the actual network,this paper presents the corresponding solutions to avoid interference for 230 MHz power wireless private network,and introduces specific measures and methods in detail.With the example of 230 MHz power wireless private network,it achieves higher efficiency in practical application. |
