【摘要】:供水計(jì)量是水司運(yùn)營中最重要的環(huán)節(jié),在二次供水和一戶一表的政策推行之后,機(jī)械水表抄表任務(wù)劇增,人工上門抄讀工作量大,抄表準(zhǔn)確度低,許多室內(nèi)水表難于抄見,抄表人員也無法監(jiān)管。而且上門抄表,也有安全隱患。智能遠(yuǎn)傳水表發(fā)展多年,因?yàn)閮r(jià)格高,維護(hù)難,還存在電源問題、機(jī)電同步問題,水司使用起來困難比較多。因此目前市面上使用中的80%以上還是機(jī)械水表,而機(jī)械水表的抄表效率低下,極為不適應(yīng)信息化的需求。在智慧城市建設(shè)中,對機(jī)械水表進(jìn)行快速便捷的智能化改造,尤為重要。因此,本文采用了一種快捷簡便的方式,在不更改任何機(jī)械水表部件的前提下,完成機(jī)械水表的智能化,實(shí)現(xiàn)遠(yuǎn)程抄表。該系統(tǒng)只需要在原有的水表上安裝一個(gè)攝像模塊,成本低廉,實(shí)現(xiàn)簡便,準(zhǔn)確安全。該方案中,水表計(jì)量與采集與通訊相互分離,各司其職,各自保證高效能,使整個(gè)系統(tǒng)快速、安全,節(jié)能,高效。實(shí)踐證明,通過此設(shè)計(jì),機(jī)械水表很方便就可以轉(zhuǎn)換為物聯(lián)網(wǎng)水表,成為智慧計(jì)量的傳感器。本文基于機(jī)器視覺和圖像識別,采取了兩種方式完成機(jī)械水表抄表任務(wù)。一種方式是以手機(jī)拍照來取得水表讀數(shù),通過云端識別水表讀數(shù)。另一種方式是在機(jī)械水表上直接安裝攝像模塊,完成圖像采集,通過云端識別來讀取水表讀數(shù),并存儲現(xiàn)場圖像,便于抄表和管理,也便于核查比對。旋翼式多流束水表顯示部分一般是字輪式,字輪的數(shù)字讀取系統(tǒng)的設(shè)計(jì)主要有:光學(xué)成像模塊設(shè)計(jì),圖像采集、圖像分析、模數(shù)轉(zhuǎn)換模塊設(shè)計(jì)、人機(jī)接口模塊設(shè)計(jì)、集中器設(shè)計(jì)和移動端APP設(shè)計(jì)。該系統(tǒng)已經(jīng)過硬件設(shè)計(jì)和軟件程序嵌入,實(shí)現(xiàn)了固定式和移動式兩種抄表功能。本文首先介紹系統(tǒng)的整體設(shè)計(jì)思想和設(shè)計(jì)相關(guān)要點(diǎn),然后分章節(jié)具體介紹各功能模塊的實(shí)現(xiàn)方法。
[Abstract]:The metering of water supply is the most important link in the operation of the Water Department. After the implementation of the policy of secondary water supply and one meter per household, the task of mechanical water meter reading has been greatly increased, the workload of manual door-to-door reading is large, the accuracy of meter reading is low, and many indoor water meters are difficult to copy. Meter reading personnel can not be supervised. Moreover, there are hidden dangers to safety when reading meters at home. Intelligent remote water meters have developed for many years because of high prices, difficult maintenance, problems with power supply and electromechanical synchronization. It is more difficult for the Water Division to use. Therefore, more than 80% meters in use on the market at present are still mechanical water meters, and the reading efficiency of mechanical water meters is so low that they are extremely unsuitable for the needs of information. In the construction of intelligent cities, It is very important to carry on the quick and convenient intelligent transformation to the mechanical water meter. Therefore, this paper adopts a quick and simple way to accomplish the intellectualization of the mechanical water meter without changing any parts of the mechanical water meter. The system only needs to install a camera module on the original water meter, which is cheap, simple, accurate and safe. In this scheme, the metering and collecting of water meter are separated from each other, their respective duties are performed, and their respective high efficiency is guaranteed. It is proved by practice that the mechanical water meter can be easily converted into an Internet of things water meter and become a smart metering sensor. This paper is based on machine vision and image recognition. Two methods are adopted to accomplish the task of reading the water meter by mechanical meter. One is to take pictures of the water meter by mobile phone to get the water meter reading, and the other is to directly install the camera module on the mechanical water meter to complete the image collection. Through cloud recognition to read water meter readings, and store field images, easy to meter reading and management, but also easy to check and compare. Rotary-wing multi-flow beam water meter display part is generally word wheel, The design of digital reading system of word wheel mainly includes: optical imaging module design, image acquisition module, image analysis module design, analog to digital conversion module design, man-machine interface module design. Design of concentrator and APP of mobile terminal. The system has been embedded in hardware design and software program, realizing two functions of fixed and mobile meter reading. This paper first introduces the whole design idea of the system and the key points of the design. Then it introduces the realization method of each function module in detail.
