  自2009年,智能电表换装工作全面启动以来,我国各省市智能电表的覆盖率不断提升,根据相关资料,目前国网片区的智能电表覆盖率已经达到80%,全国范围覆盖率也已经达到70%以上。伴随着智能电表大规模普及而来的却是从未停止过的争议,那么,当前关于智能电表这一“神器”又有哪些热点话题呢?OFweek仪器仪表网编辑对此作了一个简单的汇总分析。


争议一:智能电表普遍安全性,易被黑客攻击?

  安全公司Vaultra的联合创始人Netrael Rubin指出,目前智能电表普遍缺乏安全性,黑客可以通过恶意代码切断家用电源,甚至会通过过载导致发生爆炸或者引发火灾。事实上,Netrael Rubin的这些警告并非是预见性的假设,早在2009年,波多黎各大量智能电表被黑客攻击,导致大规模的计费错误。而在2015年,加拿大安大略省一处房子因为智能电表发生故障而引发火灾。

智能电表的物理安全性是很强的,其不安全的根源在于所使用的协议已经过时,很多智能电表使用的是GSM等2G通信协议,这种协议具有众所周知的缺陷,譬如攻击者完全可以通过伪基站来实现与设备相连。在GSM通信协议中,设备需要接受基站的安全验证,但基站并不需要设备验证,因此黑客可以通过伪基站将自己的命令发送至设备。更为糟糕的是,同一个公司的智能电表往往会使用相同的硬件编码。Netrael Rubin指出,“如果攻击者获得了对一个智能电表的访问权,其也就可以访问相同公司的其他设备。”

争议二:智能电表走得快,电费翻番?

  自换装智能电表之后,就有不少市民反映智能电表“走的快”,用电量比之前多了很多。对此,很多市民怀疑智能电表在出厂时被人做了手脚,有猫腻。针对市民的困惑,供电部门解释说是因为智能电表更加敏感,它的精确度可以到小数点后两位,所以家中的很多细微的电流也被智能电表记录在案了。

很多家庭不注意用电的细节,一个机顶盒长期处于待机状态,一个月竟会耗电达10度,还有诸如电视剧、电脑等处于待机状态中,各种充电器还插在电源上。这些尽管用电量很微小,也会被智能电表记录下来,长久累计之后数量就会非常可观。

编辑总结

智能电表已经不是传统意义上的电能表,它代表着未来节能型智能电网智能化终端的发展方向,智能电表的普及有着革命性的意义。消除争议带来的负面影响,也是企业和社会迫切需要解决的问题。
