            智能水表現階段瓶頸問題及解決方法
            作者: manager 來源:www.goliathboards.com 瀏覽: 發布日期:2019-09-26

            智能水表從開展之初到往常算來曾經有近20年的時間了,想想經過風風雨雨的這么多年,很多人都在抱怨智能水表開展太慢,也經常有人抱怨我國的供水企業對智能水表的推行力度不夠,從而招致智能水表的開展遲緩。

            Intelligent water meter has been developed for nearly 20 years from its inception to the usual calculation. Considering that after so many years of ups and downs, many people complain that the development of intelligent water meter is too slow, and some people often complain that the implementation of intelligent water meter by water supply enterprises in our country is not enough, which leads to the slow development of intelligent water meter.

            我們今天從另一個角度來剖析一下智能水表(我們這里所指的“智能水表”是指以傳統的機械式水表為根底,加上有電子器件以完成預付費或信息遠傳的“帶電子安裝的水表”)在我國開展遲緩的一個要素,望能惹起大家的關注。

            Today, we will analyze the intelligent water meter from another angle, which is based on the traditional mechanical water meter and has electronic devices to complete the prepaid or remote transmission of information. It is hoped that the slow development of the intelligent water meter in our country will arouse everyone's concern. Note.

            不知大家留意過這樣一個現象沒有:即每當智能水表的市場有較大的開展的時分,常常由于我們的產質量量呈現嚴重的問題而周期性地塌縮。這里面固然有一些大廠家將其見怪為“供水企業選用質量較差的產品所致”的緣由,但我們倒要問:難道真的都是這樣的嗎?我們就敢保證全部用我們的產品就沒有呈現問題而萬無一失嗎?我看一定,不置信捫心自問:如下問題,我們到底處理了幾供電電池的選擇和運用目前很多廠家都將電池只作為一個能源提供者,而且也不去研討電池的性能和容量對智能水表的影響;這里面存在幾個問題:

            I do not know if you have noticed such a phenomenon: whenever the smart water meter market has a greater development, often due to our production and quality of serious problems and periodic collapse. Although there are some big manufacturers blame it for "poor quality products selected by water supply enterprises", but we would like to ask: is this really the case? Are we guaranteed that there will be no problems with all our products? I don't believe that we should ask ourselves the following questions: how many batteries have been selected and used? At present, many manufacturers only regard batteries as an energy provider, and they don't discuss the impact of battery performance and capacity on smart water meters.

            首先,大家對選用的電池容量和與本人設計和選用的線路板的有效容量沒有認真的計算和明晰的認識,目前大家所選用的電池(不論是CR18505S/M,還是ER18505S/M),是缺乏以支撐目前的智能水表(主要指IC卡預付費水表)正常工作6+1年的(普通只能運用2年至3年),只是大家貪圖這種電池廉價而已。有的人辯白說他們所運用的電池有的運用了8年依然沒問題,我們倒想問一問這些廠家,你們又怎樣曉得這個電池8年都在正常工作呢(鋰氬電池在不工作的狀態下,10年以上依然有90%的電都是正常的)?同時,為什么不去想一下,大量的電池為什么又只能用2年到3年呢?

            First of all, we do not have a careful calculation and clear understanding of the selected battery capacity and the effective capacity of the circuit board designed and selected by ourselves. At present, the batteries we choose (whether CR18505S/M or ER18505S/M) are lack of intelligent water meter (mainly IC card prepaid water meter) to support the normal work of 6. + For one year (usually only two to three years), it's just that people are greedy for cheap batteries. Some people argue that some of the batteries they use are still okay after eight years. We would like to ask these manufacturers, how do you know that the batteries have been working normally for eight years (90% of the batteries are still working in the absence of lithium-argon batteries for more than 10 years)? At the same time, why not think about why a large number of batteries can only be used for two to three years?

            另外,國外對電池的在線檢測工藝和辦法在我國鮮有廠家控制(譬如無損傷檢測電池性能的工藝和辦法我國目前不論是電池消費廠或運用單位都還沒有)。各位又試想一下,諸位的智能水表從設計到消費,其工藝又有幾細節還需求完善(還不是急功近利地向市場投放不完善以至存在致命缺陷的產品)?

            In addition, there are few overseas on-line battery testing processes and methods controlled by manufacturers in our country (for example, non-destructive battery performance testing processes and methods are still not available in our country, whether in battery consumption plants or application units). Think again, from design to consumption, how many details of your smart water meters still need to be perfected (not to rush to put imperfect products into the market even with fatal defects)?

            信號采樣問標題前至少濕式IC卡預付費水表的采樣大局部都采用在采樣圈(也叫發信圈)內裝干簧管的方式,這種方式的最大問題是:采樣圈和干簧管容易被壓罩在裝配時壓裂而受損,特別是有些干簧管被隱形壓裂(在工廠內測試沒有問題,用于現場后才呈現毛?。?,更是存在很大的隱患。

            At least most of the samples of the wet IC card prepaid water meter before the title of signal sampling are installed with a dry reed tube in the sampling ring (also known as the sending ring). The biggest problem of this method is that the sampling ring and the dry reed tube are easily fractured and damaged by the pressure cover during assembly, especially some dry reed tubes are invisibly fractured (measured in the factory). There is no problem in the trial, but there is a great hidden danger when it is used on the spot.

            對電路板、電池、執行器等電子器件的防護目前很多廠家為理解決智能水表實踐被處在暗淡濕潤等環境,都用灌膠的方式將其電路板封裝在一個塑料盒內,電池則用“防水電池”,執行器則用少量的膠將其密封在其構造上。外表上,好似處理了智能水表的防護問題,但其實只不過是掩耳盜鈴而已,其理由如下:

            At present, many manufacturers encapsulate their circuit boards in a plastic box by gluing, while the batteries are "waterproof batteries" and the actuators are sealed with a small amount of glue in order to solve the problem that the practice of intelligent water meters is in dim and wet environment. Apparently, it seems to have dealt with the protection of intelligent water meters, but in fact, it's just a cover-up for stealing the bell. The reasons are as follows:

            首先,用灌膠的辦法將電路板封裝起來,外表上來看,仿佛是處理了對電路板的防護。但是,細致的研討能夠得出結論:這種灌膠的辦法對電路板而言只是短期的,由于,隨著時間的推移,空氣中的水分和氧分子會從與電路板相連的信號線(該類信號線多為多股絞股線)的絞股中間的間隙進入電路板(本處還未列出有些廠家用硬膠灌封時形成的與塑料件之間的伸縮縫);另外,空氣中的氧氣會腐蝕電路板的金屬(包括電路板上PCB的附銅線等),空氣中的濕潤水分會使電路板上某些器件(譬如電容和電池等)漏電。

            Firstly, the circuit board is encapsulated by glue filling, which seems to be dealing with the protection of the circuit board. However, careful study can conclude that this method of glue filling is only short-term for PCB, because over time, moisture and oxygen molecules in the air will enter the circuit board from the gap between the strands connected to the circuit board (which are mostly multi-stranded strands). List the expansion joints between plastic parts and hard glue from some manufacturers. In addition, oxygen in the air will corrode the metal of PCB (including copper wires attached to PCB on PCB) and moisture in the air will cause leakage of some devices (such as capacitors and batteries) on PCB.

            其次,電池采用防水電池,外表上看來,也算是處理了電池的防水,但是殊不知,為了換電池而采用的銜接處依然是有漏電的破綻的(有的廠家痛快不再設置改換電池銜接線,直接將電池連線與電路板銜接,試問:這怎樣換電池?),所以目前的智能水表的電池防護是不合格的。

            Secondly, water-proof batteries are used in batteries, which are also treated as water-proof batteries in appearance, but it is unknown that there is still a leak in the junction used for battery replacement (some manufacturers are happy to stop setting the replacement battery connection line and connect the battery connection with the circuit board directly. How to change the electricity? Pool? Therefore, the current battery protection of smart water meters is not qualified.

            再者,目前很多廠家都用少量的涂膠方法對執行器的防護,我們權且不談目前大局部廠家所運用的膠是多孔膠(譬如704膠),基本防不住空氣中水分和氧氣的進入。就從涂膠的效果來看,由于存在其不平均性等要素,這種辦法也是防不住空氣中水分和氧氣的進入的。一旦有空氣中水分和氧氣進入執行器內部,其內的金屬(銅件和鐵件)件就會被腐蝕生銹,從而影響執行器的正常工作。對防護而言,做不好的防護還不如不做,假如不做,遇到枯燥的氣候,被防護的器件四周還能夠是枯燥的(

            Moreover, at present, many manufacturers use a small amount of glue coating method to protect the actuator. We can not say that most of the glue used by manufacturers is porous glue (such as 704 glue), which can not basically prevent moisture and oxygen from entering the air. From the effect of glue coating, because of its inequality and other factors, this method can not prevent moisture and oxygen from entering the air. Once moisture and oxygen in the air enter the actuator, the metal (copper and iron) parts will be corroded and rusted, thus affecting the normal operation of the actuator. As far as protection is concerned, it's better not to do bad protection. If not, in the face of dry climate, the device protected around can also be boring. http://www.goliathboards.com/
