Description

一种基于Z i gbee的超低功耗输电线路连接点无源无线测温预警系统
技术领域
[0001] 本专利属于电力输送线路监测技术领域,可用于高压输电线路连接金具节点的温度监控,并对可能发生的线路高温情况进行预警。背景技术
[0002] 长期以来,电力部门对于线路、变电站等电气设备的节点发热情况采用人工巡检的方式,随着电网发展,输电线路越来越长,覆盖面积越来越广,人力成本大大增加。同时, 电力系统的大趋势是向自动化,无人化发展。然而,用户需求的日益增长,线路负荷更是日趋增加,电气连接节点的发热情况日益严重,这将严重影响电力系统运行稳定性。因此,电力系统节点发热情况的检测,必须具有数据远程传送且能够持续进行节点温度状态监控。
[0003] 输电线路作为电力系统中的输电通道,其导线、变压器连接节点温升最大,这直接影响着整条电网的输电能力。输电线路负荷增高,连接节点发热最快,持续监测节点温度, 可以对输配电部门提出警示,使得控制负荷,得到控制连接点在安全温度范围内,合理的安排人员检查,同时可以预测与防御事故,为电网供电安全提供重要保障,而且在电力市场运营模式下,温升预测的精度也关系到电力部门的经济利益。
[0004] 现在国内外对于节点温度监控装置的数据传输频率有433MHz和2.4GHz两种, ZIGBEE模块通用2.4GHz标准,数据传输稳定,距离远,功率低,组网自由,是做无线测温节点的首选通信方式。433MHz标准的设备,通信极易收到外界干扰,组网单一,节点数量限制,各项数据均低于2.4GHz标准。
[0005] 安装方式上,常见有抱箍安装于导线夹或者电气节点上,有机胶类粘合在电气节点附近平面,螺帽顶端安装等。这些方式均非直接接触测温表面,测得数据随节点温度变化有较大滞后。不利于依据温度数据变化预测线路温度变化。采用铝合金件直接安装在测温节点螺丝上,最大面积接触待测点,同时不影响电气节点的固定性能,可以使数据更加接近实际温度,有利于报警预测。
[0006] 综合使用ZIGBEE无线组网标准,配合小型化低功耗的测温节点,主站汇总装置采用感应取电,可汇总大量节点数据,GPRS网络发送数据回到系统后台,进行温升预警的综合系统,还未见相同装置方案。发明内容
[0007] 本实用新型的目的在于提供一种基于zigbee的超低功耗输电线路连接点无源无线测温预警系统,以解决上述背景技术中提出的问题。
[0008] 为实现上述目的,本实用新型提供如下技术方案:
[0009] 一种基于zigbee的超低功耗输电线路连接点无源无线测温预警系统,包括无源无线测温传感节点装置、GPRS模块、现场接收主机装置、前置机和数据服务器;所述无源无线测温传感节点装置在线路节点上通过ZIGBEE方式与现场接收主机装置连接;所述现场接收主机装置在输电线路上与GPRS模块连接;所述GPRS模块与前置机连接;所述前置机与数据服务器连接。
[0010] 作为本实用新型的优选方案:所述无源无线测温传感节点装置内装嵌入式微处理器,在嵌入式微处理器的两侧设有连接端口,其中一条端口连接有温度传感器和时钟模块, 另一条端口连接有高性能锂电池电源模块和ZigBee模块。
[0011] 作为本实用新型的优选方案:所述现场接收主机装置包括嵌入式微处理器和连接在嵌入式微处理器上的线路温度传感器、环境温度传感器、日照辐射模块、感应取电电源模块、GSM\GPRS模块和ZigBee接收模块。[〇〇12]与现有技术相比,本实用新型的有益效果是:本实用新型基于zigbee的超低功耗输电线路连接点无源无线测温预警系统通过设计便于安装的超低功耗节点温度检测装置, 通过ZIGBEE技术,自由组网,最后通过GPRS网络发送数据汇总后台。有效减少了人工巡检成本,同时降低设备维护成本,提出过高负荷控制建议,使电网运行更加安全可靠,为电力调度部门科学调度提供决策依据。附图说明
