Pakuphatikiza zida zama module a laser rangefinder, RS422 ndi TTL ndi njira ziwiri zoyankhulirana zomwe zimagwiritsidwa ntchito kwambiri. Amasiyana kwambiri pamayendedwe opatsirana komanso zochitika zomwe zimagwira ntchito. Kusankha protocol yoyenera kumakhudza mwachindunji kukhazikika kwa kufalitsa kwa data ndi kuphatikiza bwino kwa gawoli. Mitundu yonse yamitundu yosiyanasiyana pansi pa Lumispot imathandizira kusinthika kwapawiri-protocol. Pansipa pali kufotokozera mwatsatanetsatane za kusiyana kwawo kwakukulu ndi malingaliro osankhidwa.
I. Matanthauzo Apakati: Kusiyana Kofunikira Pakati pa Ma Protocol Awiri
● TTL Protocol: Njira imodzi yolumikizirana yomwe imagwiritsa ntchito mlingo wapamwamba (5V / 3.3V) kuimira "1" ndi mlingo wochepa (0V) kuimira "0", kutumiza deta mwachindunji kudzera mu mzere umodzi wa chizindikiro. Gawo laling'ono la 905nm la Lumispot litha kukhala ndi protocol ya TTL, yoyenera kulumikizana ndi zida zazifupi.
● RS422 Protocol: Imatengera njira yoyankhulirana yosiyana, kutumiza zizindikiro zosiyana kupyolera mu mizere iwiri ya zizindikiro (A / B mizere) ndi kuthetsa kusokoneza pogwiritsa ntchito kusiyana kwa zizindikiro. Lumispot's 1535nm mtunda wautali module imabwera ndi protocol ya RS422, yopangidwira zochitika zamafakitale azitali.
II. Kuyerekeza Kwamagwiridwe Ofunika: Miyeso ya 4 Core
● Kutalikirana: TTL protocol nthawi zambiri imakhala ndi mtunda wotumizira wa ≤10 mamita, yoyenera kugwirizanitsa mtunda waufupi pakati pa ma modules ndi ma microcomputer a single-chip kapena PLCs. Protocol ya RS422 imatha kukwaniritsa mtunda wofikira mpaka 1200 metres, kukwaniritsa zosowa zapamtunda wautali zachitetezo chamalire, kuyang'anira mafakitale, ndi zochitika zina.
● Luso Loletsa Kusokoneza: Protocol ya TTL imatha kusokonezedwa ndi ma elekitiromagineti ndi kutayika kwa chingwe, ndikupangitsa kuti ikhale yoyenera m'malo osasokoneza m'nyumba. Mapangidwe osiyanitsa a RS422 amapereka mphamvu zotsutsana ndi kusokoneza, zomwe zimatha kukana kusokonezedwa ndi ma elekitiroma muzochitika zamafakitale komanso kutsika kwazizindikiro m'malo ovuta akunja.
● Njira Yopangira Wiring: TTL imagwiritsa ntchito makina a 3-waya (VCC, GND, mzere wa chizindikiro) ndi chingwe chosavuta, choyenera kugwirizanitsa kachipangizo kakang'ono. RS422 imafuna makina a 4-waya (A+, A-, B+, B-) okhala ndi mawaya okhazikika, abwino kuti atumizidwe mokhazikika pamafakitale.
● Kuthekera kwa Katundu: Protocol ya TTL imangothandizira kulankhulana pakati pa chipangizo chimodzi chachikulu ndi chipangizo chimodzi cha akapolo. RS422 imatha kuthandizira ma network a 1 master chipangizo ndi zida 10 za akapolo, kusinthira kumitundu ingapo yolumikizirana.
III. Protocol Adaptation Ubwino wa Lumispot Laser Modules
Ma module onse a Lumispot laser rangefinder amathandizira ma protocol awiri a RS422/TTL:
● Zochitika Zamakampani (Border Security, Power Inspection): RS422 protocol module ndiyofunikira. Mukaphatikizidwa ndi zingwe zotetezedwa, zolakwika pang'ono pakutumiza kwa data mkati mwa 1km ndi ≤0.01%.
● Zochitika za Ogula / Zautali Waufupi (Drones, Handheld Rangefinders): TTL protocol module imakonda kugwiritsa ntchito mphamvu zochepa komanso kusakanikirana kosavuta.
● Thandizo Lokonzekera: Ntchito zosinthika ndi kusintha kwa makonda zimapezeka potengera zosowa za makasitomala a chipangizo, kuchotsa kufunikira kwa ma modules owonjezera komanso kuchepetsa ndalama zogwirizanitsa.
IV. Zosankha Zosankha: Kufananiza Moyenera ndi Demand
Pachimake chosankha chagona pa zofunika ziwiri zofunika: choyamba, mtunda wotumizira (sankhani TTL kwa ≤10 mamita, RS422 kwa ＞10 mamita); chachiwiri, malo ogwirira ntchito (sankhani TTL ya malo opanda zosokoneza, RS422 ya mafakitale ndi kunja). Gulu laukadaulo la Lumispot limapereka upangiri waulere wosinthira ma protocol kuti athandizire kukwaniritsa docking mosasunthika pakati pa ma module ndi zida mwachangu.
