在咱们的(de)(de)日常生(sheng)活之中,越(yue)(yue)来(lai)(lai)越(yue)(yue)多的(de)(de)通用(yong)(yong)(yong)无(wu)线遥(yao)控(kong)器(qi)的(de)(de)运(yun)用(yong)(yong)(yong)变得(de)广泛起来(lai)(lai),比如(ru)轿车电(dian)子,智能家居,电(dian)动门窗(chuang),小(xiao)区出入办理,防盗报警,工业操控(kong)等(deng)范畴都运(yun)用(yong)(yong)(yong)到了无(wu)线遥(yao)控(kong)器(qi)。不过当人们在拥有了这种(zhong)无(wu)线遥(yao)控(kong)器(qi)之后(hou),假如(ru)想要(yao)让(rang)其发挥作用(yong)(yong)(yong),须要(yao)对其进行(xing)匹(pi)配,匹(pi)配成功的(de)(de)情况下才干(gan)够(gou)运(yun)用(yong)(yong)(yong)。那么通用(yong)(yong)(yong)无(wu)线遥(yao)控(kong)器(qi)究竟怎样匹(pi)配呢?下面智安宝小(xiao)编(bian)来(lai)(lai)给大家介绍。
通用(yong)无线遥控(kong)器究竟怎样匹配(pei):
一、作业频率
目前(qian)市场(chang)上(shang)绝大(da)部分的遥控(kong)器都是315M的,少数是433M、310M、430M等(deng)特别类型(xing)。
以2260、2264芯片遥(yao)控发射接纳器为(wei)例,作(zuo)业频率(lv)和芯片类型的(de)(de)(de)查找方法: 以常见的(de)(de)(de)四键遥(yao)控器为(wei)例,翻开(kai)遥(yao)控器外壳,看到线路板上声(sheng)表元件(像一(yi)个(ge)小(xiao)金属(shu)钮(niu)扣或许相似(si)晶振的(de)(de)(de)元件)上的(de)(de)(de)数值为(wei)R315A,表示315MHz。
二、发射接纳(na)芯(xin)片
编(bian)码芯(xin)片便(bian)是线(xian)路(lu)(lu)板(ban)上的集(ji)成(cheng)(cheng)电(dian)路(lu)(lu),类型在集(ji)成(cheng)(cheng)电(dian)路(lu)(lu)表面上能够找到(dao)。
遥控按编码(ma)形(xing)式可(ke)分为三种(zhong)类型:
1、固定码遥控器
又称编(bian)码遥(yao)控器(qi),焊(han)码遥(yao)控器(qi),常用(yong)发(fa)射(she)芯片PT,SC,HS,LX (2260/2262/2264),配(pei)对接纳芯片为(wei)PT,SC,LX,HS(2270/2272/2294)。发(fa)射(she)和接纳的编(bian)码相同才干正确配(pei)对运(yun)用(yong)。也便(bian)是说,把新的遥(yao)控器(qi)的编(bian)码区(qu)和接纳器(qi)的编(bian)码区(qu)焊(han)成相同就(jiu)能够了。
2、学(xue)习(xi)码遥控器
常(chang)用发(fa)射芯片EV,HS,LX,SC (1527/2240),HCS101等(deng)。配(pei)对的接(jie)纳(na)为主机内带有程序(xu)的存(cun)贮IC,单(dan)片机等(deng)。
3. 滚动码遥控器(qi)
常用的(de)发射芯片有HCS301/200/201等,配对的(de)接纳的(de)类型和(he)功(gong)能和(he)学习码遥控器(qi)相(xiang)同(tong)。
三、振动电阻
振动(dong)(dong)电(dian)阻便是普通(tong)电(dian)阻,在这里能够决定振动(dong)(dong)的(de)频(pin)率(lv)。
2264芯(xin)片(pian)(pian)遥控器震动电阻的(de)(de)查找(zhao)方法:通常(chang)在RC位置(zhi),即(ji)2264芯(xin)片(pian)(pian)的(de)(de)第十(shi)五~16脚之(zhi)间,假如不(bu)(bu)能(neng)找(zhao)到,两脚之(zhi)间的(de)(de)对应的(de)(de)线路板(ban)不(bu)(bu)和的(de)(de)那(nei)只贴(tie)片(pian)(pian)电阻便是震动电阻,电阻上有数字,通常(chang)为125、155、225、335、475中某一个数值。
这(zhei)些电阻数值应该不必多(duo)说,例如125=12*10^5=1200KΩ=1.2M Ω
475=47*10^5=4700 KΩ=4.7
204=20*10^5=2 M Ω
以上(shang)内容便(bian)是(shi)(shi)对通用无线(xian)(xian)遥(yao)(yao)控(kong)器究竟怎样匹(pi)配(pei)的(de)介绍了(le),发(fa)射接(jie)纳芯(xin)片也(ye)是(shi)(shi)整个无线(xian)(xian)遥(yao)(yao)控(kong)操控(kong)过程中很常见的(de)一(yi)种重(zhong)要组(zu)成部(bu)分,它是(shi)(shi)线(xian)(xian)路(lu)板上(shang)的(de)一(yi)种集(ji)成线(xian)(xian)路(lu),类型是(shi)(shi)在(zai)集(ji)成电(dian)路(lu)表面是(shi)(shi)能够找到的(de),在(zai)进行(xing)匹(pi)配(pei)的(de)时(shi)候(hou)须要将其进行(xing)正(zheng)确类型的(de)选择。只(zhi)要在(zai)这些方面做好了(le)充(chong)分的(de)匹(pi)配(pei)之后(hou),才(cai)干让无线(xian)(xian)遥(yao)(yao)控(kong)器发(fa)挥重(zhong)要作用。
