影(ying)响无线电遥控距离的(de)要(yao)素主要(yao)有如下(xia)几点:
1、发(fa)射功率(lv)(lv):发(fa)射功率(lv)(lv)大(da)则距离远,但(dan)耗电大(da),简(jian)略产生烦扰;
2、接(jie)收灵(ling)敏度:接(jie)收器的接(jie)收灵(ling)敏度前进,遥控(kong)(kong)距离增大,但简略受烦扰(rao)构成误动或(huo)失(shi)控(kong)(kong);
3、天(tian)线:选用直(zhi)线型天(tian)线,而(er)且(qie)彼(bi)此平行,遥控(kong)距离(li)(li)远,但占(zhan)有空间大(da),在运用中把天(tian)线拉(la)长、拉(la)直(zhi)可增加遥控(kong)距离(li)(li);
4、高(gao)度:天线越(yue)高(gao),遥控距离(li)越(yue)远,但受客(ke)观条(tiao)件(jian)约束(shu);
5、阻遏:现在运用的(de)无(wu)线遥(yao)控(kong)器运用国家规定的(de)UHF频段,其传播(bo)特(te)性和光近似,直线传播(bo),绕射较小,发射器和接收器之间(jian)如有墙面(mian)阻遏将大大打(da)折遥(yao)控(kong)距(ju)离,如果(guo)是钢筋(jin)混泥(ni)土的(de)墙面(mian),由于(yu)导体对电波的(de)吸收效果(guo),影响更甚。

无线遥控(kong)(kong)器(qi)厂(chang)家:工业(ye)无线遥控(kong)(kong)器(qi)的功率和(he)电(dian)池有什么(me)关系
工业无线(xian)遥(yao)控(kong)器(qi)(qi)发射器(qi)(qi)的(de)(de)功率和(he)电(dian)(dian)池有(you)什(shen)么关(guan)系?工业无线(xian)遥(yao)控(kong)器(qi)(qi)广泛应用于电(dian)(dian)子操控(kong)工业设备(bei)的(de)(de)无线(xian)电(dian)(dian)操作。工业无线(xian)遥(yao)控(kong)器(qi)(qi)体积小,便于携带,无需长电(dian)(dian)线(xian)或固(gu)定(ding)方(fang)位即可操作。在售后购买工业无线(xian)遥(yao)控(kong)器(qi)(qi)时,除了考虑(lv)功率效率、价格和(he)质量外,还(hai)须留意发射机的(de)(de)供电(dian)(dian)方(fang)式、电(dian)(dian)池的(de)(de)工作时刻、接收机的(de)(de)电(dian)(dian)源(yuan)电(dian)(dian)压和(he)以及输出电(dian)(dian)路的(de)(de)功
