/ / / /浅析通过USB鼠标直接采集测速信号Acquisition speed signal directly by USB mouse is analysed 河流流量检验与整编是水文最基本的作业内容。半个多世纪以来，流速仪法一直是流量检验最基本的测速办法，各类新的测速仪器甚至多普勒流量计ADCP的呈现，仍然在大都检验条件下不能替代传统的流速仪。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. 广阔水文科技人员为进步检验质量不断改进计数、计时设备，还研制出能够直接衔接流速仪的流速测算仪并能够同核算机通讯。但毋庸置疑，不能直接衔接核算机或脱离核算机系统控制的任何领先设备，因受其灵活性和可开发性所限，其自动化、智能化、信息化水平的进步必然会遭到约束，并且信息的收集与处置即检验与整编是脱节的。今日便携式核算机的遍及标志着手提核算机到断面检验的条件现已老练，而开发使用这一资源的瓶颈是如何故最简略的办法使核算机直接纳集测速信号。 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. 在现有流速仪测速信号作业原理的基础上，运用单片机同核算机串口通讯，明显能够描绘一个由发射接纳处置级作业站式的有线或无线信号系统，笔者也经过试验并获成功。可是，关于流速仪测速设备和实践中许多船测、桥测作业的简略性，给核算机添加硬件设备无疑又会使检验进程复杂化，有必要思考使用核算机自带的输入设备才是最简略和最佳挑选，而便携式核算机最便于使用的设备是USB接口的鼠标。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. 鼠标的简略改装，鼠标替代信号器的可行性，作为核算机输入设备的鼠标其按键是触点式无源信号，而流速仪的特点和作业原理恰恰与之一样，检验中需求的水面、河底信号也无外乎是经过衔接断开来得到。理论上经过衔接鼠标的按键触点来使核算机得到测速信号是可行的，并且鼠标的高灵敏度足以保证信号的可靠性。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. 一个规范的普通型的鼠标外部由左中右3个按键组成，内部是一块主板，除向核算机传送3个按键信号外实木复合门，还有一路取自核算机的5v电源。其左键和右键均担负着很多输入使命，唯有中键几乎是个搁置资源，明显能够用导线衔接鼠标主板的这两个引脚来用于获取测速信号，核算机软件控制这一路信号完全能够完结测速山东太阳能、核算及其他剖析作业，并且软件的开发来完成其智能化将不再遭到其他任何资源的约束，能够充沛补偿传统信号系统的任何缺点和缺乏。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. 改装鼠标的办法，若是测速设备都做好绝缘处置即不思考水的导电性，则借用鼠标中键引出两根导线直接衔接测速设备的水面、流速仪和河底信号源即可复合土工膜。Modified mouse, if the speed measuring equipment are properly insulati
