Kusiyana Pakati pa RS422 ndi TTL Communication Protocols: Lumispot Laser Module Selection Guide

I. Matanthauzo Aakulu: Kusiyana Kofunika Pakati pa Ma Protocol Awiriwa
● TTL Protocol: Protocol yolumikizirana yokhala ndi gawo limodzi yomwe imagwiritsa ntchito mulingo wapamwamba (5V/3.3V) kuyimira "1" ndi mulingo wotsika (0V) kuyimira "0", kutumiza deta mwachindunji kudzera mu mzere umodzi wa chizindikiro. Module yaying'ono ya Lumispot ya 905nm ikhoza kukhala ndi protocol ya TTL, yoyenera kulumikizana mwachindunji ndi chipangizo chapafupi.
● RS422 Protocol: Imagwiritsa ntchito kapangidwe kosiyana ka kulumikizana, kutumiza zizindikiro zosiyana kudzera mu mizere iwiri ya zizindikiro (mizere ya A/B) ndikuchepetsa kusokoneza pogwiritsa ntchito kusiyana kwa zizindikiro. Gawo la mtunda wautali la Lumispot la 1535nm limabwera ndi protocol ya RS422, yopangidwira makamaka zochitika zamafakitale akutali.
II. Kuyerekeza kwa Magwiridwe Abwino: Miyeso 4 Yapakati
● Mtunda Wotumizira: Njira ya TTL nthawi zambiri imakhala ndi mtunda wotumizira wa ≤10 metres, yoyenera kugwirizanitsa mtunda waufupi pakati pa ma module ndi ma microcomputer a single-chip kapena ma PLC. Njira ya RS422 imatha kufikira mtunda wotumizira wa mamita 1200, kukwaniritsa zosowa za kutumiza deta mtunda wautali monga chitetezo cha malire, kuyang'anira mafakitale, ndi zochitika zina.
● Luso Loletsa Kusokoneza: Njira ya TTL imakhudzidwa ndi kusokonezeka kwa maginito ndi kutayika kwa chingwe, zomwe zimapangitsa kuti ikhale yoyenera m'malo opanda kusokoneza mkati. Kapangidwe ka RS422 kosiyana kamapereka mphamvu yolimbana ndi kusokoneza, yokhoza kukana kusokonezeka kwa maginito m'mafakitale komanso kuchepetsa zizindikiro m'malo ovuta akunja.
● Njira Yolumikizira Mawaya: TTL imagwiritsa ntchito makina a waya atatu (VCC, GND, mzere wa chizindikiro) okhala ndi mawaya osavuta, oyenera kuphatikiza zida zazing'ono. RS422 imafuna makina a waya anayi (A+, A-, B+, B-) okhala ndi mawaya okhazikika, abwino kwambiri poyika makina okhazikika m'mafakitale.
● Kutha Kunyamula: Njira ya TTL imathandizira kulumikizana pakati pa chipangizo chimodzi chachikulu ndi chipangizo chimodzi cha kapolo. RS422 imatha kuthandizira kulumikizana kwa chipangizo chimodzi chachikulu ndi zida 10 za kapolo, zomwe zimagwirizana ndi zochitika zoyendetsera ntchito zosiyanasiyana.
III. Ubwino wa Lumispot Laser Modules pa Kusintha kwa Protocol
Ma module onse a Lumispot laser rangefinder amathandizira ma protocol awiri a RS422/TTL osankha:
● Zochitika Zamakampani (Chitetezo cha Malire, Kuyang'anira Mphamvu): Gawo la protocol la RS422 limalimbikitsidwa. Mukalumikizana ndi zingwe zotetezedwa, liwiro la zolakwika za bit pakutumiza deta mkati mwa 1km ndi ≤0.01%.
● Zochitika za Ogwiritsa Ntchito/Kutalika Kwapafupi (Ma Drone, Ma Rangefinder Ogwira Ntchito): Gawo la protocol la TTL ndilabwino kwambiri chifukwa limagwiritsa ntchito mphamvu zochepa komanso limaphatikiza mosavuta.
● Thandizo la Kusintha Makonda: Ntchito zosinthira ma protocol ndi kusintha makonzedwe azinthu zimapezeka kutengera zosowa za mawonekedwe a chipangizo cha makasitomala, zomwe zimachotsa kufunikira kwa ma module owonjezera osinthira ndikuchepetsa ndalama zolumikizirana.
IV. Malangizo Osankha: Kufananiza Moyenera ndi Kufunidwa
Chofunika kwambiri pakusankha ndi ziwiri zofunika: choyamba, mtunda wotumizira (sankhani TTL ya ≤10 metres, RS422 ya ＞10 metres); chachiwiri, malo ogwirira ntchito (sankhani TTL ya malo opanda kusokonezedwa mkati, RS422 ya malo opangira mafakitale ndi akunja). Gulu laukadaulo la Lumispot limapereka upangiri waulere wosintha ma protocol kuti athandize kukwaniritsa malo olumikizirana pakati pa ma module ndi zida mwachangu.
