【摘要】 沟槽式公厕普遍使用的是虹吸式全自动冲水箱,这类冲水箱全天不间断冲水,水资源浪费非常严重。目前国内在沟槽式公厕上节水技术有了突破,研发出了智能化的节水设备。但这类智能节水设备不能利用现有的沟槽式公厕的虹吸式全自动冲水箱对公厕进行改造;红外传感检测器灵敏度较低、误检率较高,因而系统现场实时监测能力较差;冲水机理与复杂多变的入厕情况不吻合,导致不该冲厕而又冲厕的误冲厕、该冲厕而又没有冲厕的漏冲厕和冲厕不及时的现象频繁出现;在断电但是有水的情况下不能冲厕,或者不能自动冲厕,导致厕所环境卫生极差。有的智能冲水器为了能达到智能控制的目的,上水阀与下水阀均采用了电磁阀,弊端是冲厕时冲力小,冲力小可增大电磁阀口径,但这又增加了制造成本。有的公司为了增大冲厕时的冲力,投入巨额资金研发大口径的虹吸式电磁阀作下水阀。本论文正是针对上述问题,以确保冲厕及时、高效、环保、杜绝误冲厕、漏冲厕、提高节水率为主要研究内容。主要研究内容有:1.权控快启动技术研究一种快启动冲厕技术,以解决现有智能冲水器在利用普通冲水箱时冲水不及时的缺憾。水箱主要储水由水箱自储水控制电路控制储水,冲水指令到来后仅需至多5秒的权注水即可开启虹吸阀向厕所冲水,冲水及时、高效。此项技术解决现有智能冲水器在利用普通虹吸式冲水箱时冲水不及时的缺憾。2.入厕人流量现场实时监测技术研究高灵敏度、低误检率的红外传感器,以解决漏冲厕、误冲厕技术难关。3.延时优选节水技术研究一种冲水机理,解决高低峰期冲厕的冲突问题。4.防水箱渗流技术研究水箱水密技术和软件技术,以解决水箱内的水长时间存放时水因渗漏而不能及时冲厕的问题。5.防无水空冲水技术研究一种断电自动断电的技术,解决管网无水时控制器频繁启动检测有无水,造成的耗电、缩短控制器及电磁阀使用寿命的问题。6.水箱自储放水控制技术研究水箱主储水的电路控制技术,解决储水时占用CPU时间,因而造成的现场实时监测能力弱的问题。7.人工智能模糊识别技术研究能根据入厕实时情况自动冲厕的技术,智能判断入厕的高峰期和低峰期,解决误判造成的误冲厕、漏冲厕问题。8.断电自动入水管道转换技术研究一种入水管道自动转换技术,控制断电后自来水从另一个入水管道进入水箱,解决现有智能冲水器在断电后不能自动冲厕的缺憾。更多还原

【Abstract】 The groove type Mr. Ci is widespread usage of is that the Hong absorb type be full-automatic blunt water tank, this type of blunt the water tank whole day be without a break blunt water, water waste of resources very severity.Currently domestic stanza water technique haded break on the groove type Mr. Ci, development the intelligence turn of stanza water equipments.But this intelligence stanza water equipments can’t make use of the Hong absorb type of existing groove type Mr. Ci full-automatic blunt water tank to Mr. the Ci carry on reformation;Red unauthorized biography feeling detector the intelligent degree be lower, mistake check the rate be higher, as a result system the spot solid hour monitor ability more bad;Blunt water mechanism and complications much change of go into the Ci circumstance don’t fit together and cause shouldn’t blunt Ci but again blunt the mistake of Ci blunt Ci, should blunt Ci but again have no blunt leak of Ci blunt Ci with blunt Ci can not compare with of the phenomenon be multifarious to appear;Under the circumstance that power failure but have water can’t blunt Ci, perhaps can’t auto blunt Ci, cause toilet environmental hygiene very bad.Some intelligence blunt water machine for the sake of ability attain intelligence control of purpose, top water valve and enter water valve all adoption electromagnetism valve, irregularity is blunt Ci the momentum be small, the momentum is a little aggrandizement electromagnetism valve caliber, but this again increment manufacturing cost.Some company for enlarging blunt Ci of momentum, devotion a huge sum of funds development big caliber of the Hong absorb type electromagnetism valve make watering valve.This thesis aim at the above-mentioned problem, with insure blunt Ci in time, efficiently, environmental protection, eradicate completely a mistake blunt Ci, leak blunt Ci, exaltation stanza water rate is main research contents.The main research contents have:1.The power control a quick start a techniqueResearch a kind of quick start blunt Ci technique with solve existing intelligence blunt water machine at make use of common blunt water tank blunt water can not compare with of missing.The water tank is main to keep water from the water tank from keep water control electric circuit control to keep water, blunt water instruction arrival empress only need at most 5 second power to note water can immediately open Hong to absorb valve toward the toilet blunt water, blunt water in time and efficiently.This technique solve existing intelligence blunt water machine at make use of common the Hong absorb type blunt water tank blunt water can not compare with of missing.2.Go into Ci person discharge the spot solid hour monitor technique The research Gao intelligent degree, low mistake check rate of red unauthorized biography feeling the machine leak by solve blunt Ci, mistake blunt Ci technique difficult situation.3.While postpone the optimization stanza water techniqueThe research is a kind of blunt water mechanism, solve the period of Gao Di Feng blunt the conflict problem of Ci.4.The watertightness box Shen flow a techniqueThe research water tank water airtight technique and software technique with solve water in the water tank long time deposit water because of seep into but can’t in time blunt the problem of Ci.5.Defend to have no water empty blunt water techniqueResearch a kind of power failure auto power failure of technique, solve tube controller for net to have no water multifarious start examination have have no water, result in of consume electricity and shorten the problem of controller and electromagnetism valve service life.6.Water tank from keep to turn on water a control techniqueResearch water tank lord keep water of electric circuit control technique, take up CPU for time while solving to keep water, as a result result in of the spot solid hour monitor the ability weak problem.7.The artificial intelligence is misty to identify a techniqueResearch can according to go into Ci solid hour circumstance auto blunt the technique of Ci, intelligence judgment go into Ci of high peak period and low Feng period, solve the mistake that the miscarriage of justice result in blunt Ci, leak blunt Ci problem.8.Power failure auto go into pipe line way conversion techniqueResearch 1 kind go into pipe line way auto conversion technique, control behind the power failure running water from another go into the pipe line way get into water tank and solve existing intelligence blunt water machine is after cut the power can’t auto blunt the missing of Ci.更多还原
