Ntau hom tswb
Jul 31, 2022
Raws li hom sensor: magnetic hloov tswb, vibration tswb, suab tswb, ultrasonic tswb, hluav taws xob tswb tswb, microwave tswb, infrared tswb, laser tswb thiab video suab tswb. Ob hom sensors tau nruab rau hauv ib lub tshuab ntes, hu ua lub tswb nrov dual thev naus laus zis.
Raws li txoj kev ua haujlwm ntawm tus ntes, nws tuaj yeem muab faib ua active thiab passive tswb. Active detectors yuav tsum tsis tu ncua emit ib co hom ntawm lub zog, xws li infrared, ultrasonic, microwave thiab lwm yam zog, mus rau lub chaw zov me nyuam thaum lub sij hawm ceev faj. Lub passive detector nws tus kheej tsis tas yuav emit ib hom ntawm lub zog rau lub chaw zov me nyuam thaum lub sij hawm lub sij hawm ceeb toom, tab sis ncaj qha nrhiav tau ib co qauv ntawm lub zog emissions los ntawm lub hom phiaj nws tus kheej, xws li infrared, kev co thiab lwm yam zog.
Raws li kev tshawb pom ntawm hluav taws xob teeb liab kis tau tus mob channel kev faib tawm: tuaj yeem muab faib ua lub tswb tswb thiab wireless tswb.
Raws li cov lus ceeb toom: point control alarm, line control alarm, deg control alarm and space control alarm.
Kev faib tawm los ntawm daim ntawv thov: Nws tuaj yeem muab faib ua lub tswb nyob sab hauv tsev thiab sab nraum zoov, lossis tuaj yeem muab faib ua ib puag ncig lub tswb, tsim lub tswb sab nraud, tswb nrov hauv tsev thiab lub tswb rau kev saib xyuas lub hom phiaj tshwj xeeb.
