/ / / /淺析通過USB鼠標(biāo)直接采集測速信號Acquisition speed signal directly by USB mouse is analysed 河流流量檢驗(yàn)與整編是水文最基本的作業(yè)內(nèi)容。半個(gè)多世紀(jì)以來，流速儀法一直是流量檢驗(yàn)最基本的測速辦法，各類新的測速儀器甚至多普勒流量計(jì)ADCP的呈現(xiàn)，仍然在大都檢驗(yàn)條件下不能替代傳統(tǒng)的流速儀。Rivers flow test and the BGF is the basic of the hydrologic work content. More than half a century, current meter method was the most basic measures for the speed of flow test of all kinds of new speed measuring instrument and doppler flowmeter ADCP present, still under the condition of most inspection does not replace the traditional current meter. 廣闊水文科技人員為進(jìn)步檢驗(yàn)質(zhì)量不斷改進(jìn)計(jì)數(shù)、計(jì)時(shí)設(shè)備，還研制出能夠直接銜接流速儀的流速測算儀并能夠同核算機(jī)通訊。但毋庸置疑，不能直接銜接核算機(jī)或脫離核算機(jī)系統(tǒng)控制的任何領(lǐng)先設(shè)備，因受其靈活性和可開發(fā)性所限，其自動(dòng)化、智能化、信息化水平的進(jìn)步必然會(huì)遭到約束，并且信息的收集與處置即檢驗(yàn)與整編是脫節(jié)的。今日便攜式核算機(jī)的遍及標(biāo)志著手提核算機(jī)到斷面檢驗(yàn)的條件現(xiàn)已老練，而開發(fā)使用這一資源的瓶頸是如何故最簡略的辦法使核算機(jī)直接納集測速信號。 Vast hydrologic science and technology personnel for inspection quality continuous improvement progress counting, timing devices, also developed instrument can connect directly to a flow velocity measuring instrument and to be able to communicate with accounting machine. But needless to say, no direct connection accounting machine or any leading out accounting system control devices, due to its flexibility and developable, its level of automation, intelligent, information-based progress is bound to be constraints, and information collection and disposal of the test and the BGF is disjointed. Today accounting accounting machine throughout marks a portable portable machine to the cross section test conditions are sophisticated, and development of how to use this resource bottleneck machine is the most short way to make accounting directly set speed signal. 在現(xiàn)有流速儀測速信號作業(yè)原理的基礎(chǔ)上，運(yùn)用單片機(jī)同核算機(jī)串口通訊，明顯能夠描繪一個(gè)由發(fā)射接納處置級作業(yè)站式的有線或無線信號系統(tǒng)，筆者也經(jīng)過試驗(yàn)并獲成功?？墒牵P(guān)于流速儀測速設(shè)備和實(shí)踐中許多船測、橋測作業(yè)的簡略性，給核算機(jī)添加硬件設(shè)備無疑又會(huì)使檢驗(yàn)進(jìn)程復(fù)雜化，有必要思考使用核算機(jī)自帶的輸入設(shè)備才是最簡略和最佳挑選，而便攜式核算機(jī)最便于使用的設(shè)備是USB接口的鼠標(biāo)。Existing in current meter speed signal operation principle, on the basis of using single chip microcomputer with accounting machine serial port communication, and clear to describe a disposal by launch - accepted - level 3 homework station type cable or wireless signal system, the author also tried and succeeded. But about current meter speed many ships, bridge test measurement equipment and practice assignment brief sex, add hardware to accounting machine will undoubtedly complicate the testing process, it is necessary to think about accounting machine used to own input device is the brief and the best selection, machine is the most easy to use and portable accounting device is USB mouse. 鼠標(biāo)的簡略改裝，鼠標(biāo)替代信號器的可行性，作為核算機(jī)輸入設(shè)備的鼠標(biāo)其按鍵是觸點(diǎn)式無源信號，而流速儀的特點(diǎn)和作業(yè)原理恰恰與之一樣，檢驗(yàn)中需求的水面、河底信號也無外乎是經(jīng)過銜接斷開來得到。理論上經(jīng)過銜接鼠標(biāo)的按鍵觸點(diǎn)來使核算機(jī)得到測速信號是可行的，并且鼠標(biāo)的高靈敏度足以保證信號的可靠性。Brief modified mouse, the mouse instead of the feasibility of the annunciator, as accounting machine touch input device of the mouse is the key point of passive signal, and the velocity of the characteristics and operation principle is, inspection requirements of the water and riverbed signal troupe is a connect/disconnect to get. Contact theory after connecting the mouse buttons to make accounting machine speed signal is feasible, and the high sensitivity of the mouse is sufficient to ensure the reliability of the signal. 一個(gè)規(guī)范的普通型的鼠標(biāo)外部由左中右3個(gè)按鍵組成，內(nèi)部是一塊主板，除向核算機(jī)傳送3個(gè)按鍵信號外實(shí)木復(fù)合門，還有一路取自核算機(jī)的5v電源。其左鍵和右鍵均擔(dān)負(fù)著很多輸入使命，唯有中鍵幾乎是個(gè)擱置資源，明顯能夠用導(dǎo)線銜接鼠標(biāo)主板的這兩個(gè)引腳來用于獲取測速信號，核算機(jī)軟件控制這一路信號完全能夠完結(jié)測速山東太陽能、核算及其他剖析作業(yè)，并且軟件的開發(fā)來完成其智能化將不再遭到其他任何資源的約束，能夠充沛補(bǔ)償傳統(tǒng)信號系統(tǒng)的任何缺點(diǎn)和缺乏。A specification of the normal mouse from left right outside of three buttons, internal is a motherboard, except to accounting machine 3 key signal, and all the way from accounting machine of 5 v power supply. Its left and right shoulders were a lot of input mission, only key is almost a shelve resources, obviously can use wire connecting the mouse the mainboard of the two pins to gain speed signal, the accounting software to control the signal all the way to completely end speed measuring, accounting and other analysis, and the development of software to complete its intelligent will no longer have any other resource constraints, full compensation to any flaws and lack of traditional signal system. 改裝鼠標(biāo)的辦法，若是測速設(shè)備都做好絕緣處置即不思考水的導(dǎo)電性，則借用鼠標(biāo)中鍵引出兩根導(dǎo)線直接銜接測速設(shè)備的水面、流速儀和河底信號源即可復(fù)合土工膜。Modified mouse, if the speed measuring equipment are properly insulati
