Abstract: With the construction of the power IoT and the increasing popularity of smart meters, solving the problem of abnormal clock of meters and correcting the clock deviation of meters has become an increasingly important task for power companies. For prepayment meters with clock deviations exceeding 5 minutes, the current common approach is to correct them through point-to-point cipher text timing. However, the increase in the number of such meters out of tolerance will put a significant burden on the central station's timing work. In response to this issue, drawing on the concept of edge computing, which involves splitting the overall task and allocating parts of it to edge nodes for distributed completion, this article proposes a batch electricity meter calibration method based on edge computing. The method utilizes techniques such as bulk task deployment from the central station and encryption by the edge nodes, enabling batch calibration of clocks with significant differences in electricity meters, reducing the operational pressure on the central station system and improving its efficiency.

引言

近年來,,隨著電力物聯(lián)網(wǎng)的發(fā)展和智能電能表的逐步推廣以及實(shí)時(shí)費(fèi)控等功能模塊的深化應(yīng)用,,用電領(lǐng)域?qū)﹄娔鼙?a class="innerlink" href="http://forexkbc.com/tags/時(shí)鐘" target="_blank">時(shí)鐘準(zhǔn)確性要求也越來越高。

智能電能表中的時(shí)鐘通常是基于晶體振蕩器來實(shí)現(xiàn)的,,它們負(fù)責(zé)維護(hù)電能計(jì)量的準(zhǔn)確性和時(shí)間記錄,。然而,隨著設(shè)備的長期使用,,晶體振蕩器可能會(huì)受到環(huán)境因素,、溫度變化以及電子元件衰減等因素的影響,從而導(dǎo)致時(shí)鐘的不準(zhǔn)確[1],。

電能表時(shí)鐘不準(zhǔn)確可能會(huì)對用電信息采集系統(tǒng)中的電能計(jì)量和時(shí)間記錄造成一定的影響,。在電能計(jì)費(fèi)和用電統(tǒng)計(jì)方面,時(shí)鐘不準(zhǔn)確可能會(huì)導(dǎo)致能源消耗的誤判,,用戶可能會(huì)被過高或過低地計(jì)費(fèi),。此外,在時(shí)間記錄方面,,時(shí)鐘不準(zhǔn)確可能會(huì)影響到用電的時(shí)間段分析等[2],。在電力公司日常運(yùn)維工作中,解決電能表時(shí)鐘異常問題,、對時(shí)鐘超差電能表進(jìn)行校時(shí),,已經(jīng)成為一項(xiàng)越來越重要的工作[3]。為了減輕主站側(cè)的業(yè)務(wù)壓力,,借鑒邊緣計(jì)算思想,,本文設(shè)計(jì)了一種對批量時(shí)鐘超差電能表校時(shí)方法。
