摘要
传统输电铁塔组立监测系统存在无效能耗的数据传输空闲状态,致使其续航时间难以满足实际工程需求。为此,本文基于将空闲时间段的传感器转为低功耗休眠状态的思想,提出了一种适用于输电铁塔组立监测系统数据传输的M/M/1/N/∞排队模型,推导了监测系统中数据传输的分布方程,通过求解监测数据等待队长与有效输入率的比值和确定对应的数据传输轮换次数,确定了各传感器的数据传输空闲时间,实现了将处于空闲时间段的传感器转为休眠状态的低功耗工作模式。据此方法,研制的输电铁塔组立监测系统在周宁~宁德500 kV线路工程6天的实际监测过程中共耗电24%,续航时间与传统方法相比提升了1.9倍,满足监测系统续航时间大于单基铁塔组立施工周期的工程需求。
The traditional transmission tower assembly monitoring system has the idle state of data transmission with invalid energy consumption,which makes its life time difficult to meet the engineering needs.Therefore,based on the idea of turning the sensors in the idle time period into low-power sleep state,this paper proposes an M/M/1/N/∞queuing model suitable for data transmission of transmission tower assembly monitoring system,deduces the distribution equation of data transmission in the monitoring system,and determines the corresponding rotation times of data transmission by solving the ratio of mon-itoring data waiting length to effective input rate,The idle time of data transmission of each sensor is determined,and the low-power working mode of turning the sensor in the idle time period into sleep is realized.According to this method,the developed transmission tower assembly monitoring system consumes 24%of power in the 6-day actual monitoring process of Zhouning Ningde 500kV Line Project,and the endurance time is increased by 1.9times compared with the traditional method,meeting the engineering demand that the endurance time of the monitoring system is greater than the construction cycle of single base tower assembly.
