输电线路架线施工中,为了加强放线过程的有效监控,避免走板翻转等问题,开发了无线移动监控系统。比较了目前比较成熟的微波和CDMA2种方案并选用微波作为最终方案,主要完成了传输走板移动点图像设备的开发。针对监控系统特点,分析了系统开发过程中的难点,并采用了相应的技术措施:采用模数结合的方式,既满足了体积和图像要求,又使能耗较低;定制无线全向天线以达到无线发射要求;实现前端设备一体机功能,满足了其防震、防水、防尘要求。该系统已成功应用于500kV洛南л接放线施工现场及特高压工程架线施工,为今后电网项目现代化管理进行了积极的探索。
In the transmission line construction, in order to strengthen the effective monitoring of the pay-off process and avoid the problems of flip-board and so on, the wireless mobile monitoring system has been developed. Comparison of the current relatively mature microwave and CDMA2 kinds of programs and the selection of microwave as the final program, mainly to complete the transfer board moving point image equipment development. According to the characteristics of the monitoring system, the difficulties in the process of system development are analyzed, and the corresponding technical measures are adopted: the combination of modulus and number not only meets the requirement of volume and image, but also lowers the energy consumption; the customized wireless omnidirectional antenna Achieve wireless launch requirements; Front-end equipment to achieve the function of one machine to meet its shockproof, waterproof, dustproof requirements. The system has been successfully applied to 500kV Luonan л drop access construction site and construction of UHV overhead lines for the future modernization of grid project management conducted an active exploration.
