Dongosolo La Chenjezo Loyamba la Chigumula cha ku Philippines: Nkhani Yophatikizika ya Multi-Sensor Integration

I. Mbiri ya Ntchito

Monga dziko la zisumbu ku Southeast Asia, Philippines nthawi zambiri imakhudzidwa ndi nyengo zamkuntho ndi mvula yamkuntho, zomwe zimayambitsa masoka a kusefukira kwamadzi. Mu 2020, bungwe la National Disaster Risk Reduction and Management Council (NDRRMC) linayambitsa pulojekiti ya "Smart Flash Flood Early Warning System", kugwiritsira ntchito intaneti yowunikira nthawi yeniyeni yokhudzana ndi kuphatikiza kwa ma sensor ambiri m'madera omwe ali pachiopsezo cha kumpoto kwa Luzon.

II. System Architecture

1. Sensor Network Deployment

• Weather Radar System: X-band Doppler radar yokhala ndi utali wa 150km, ndikusinthira kuchuluka kwa mvula mphindi 10 zilizonse.
• Ma Flow Sensors: 15 akupanga otaya mamita kutumizidwa pa mtsinje zigawo zovuta, ± 2% muyeso kulondola
• Malo Oyang'anira Mvula: 82 telemetric mvula yoyezera (mtundu wa ndowa), 0.2mm kusamvana
• Sensor Level Level ya Madzi: Miyezo yamadzi yotengera kuthamanga kwamadzi pamalo ochepera 20 omwe amatha kusefukira

2. Network Transmission Network

• Kulumikizana koyambirira kwa 4G/LTE ndi zosunga zobwezeretsera za satellite
• LoRaWAN ya ma network akutali

3. Data Processing Center

• GIS-based chenjezo nsanja
• Makina ophunzirira mvula-kuthamanga kwa mvula
• Chenjezo pofalitsa mawonekedwe

III. Zofunikira Zaukadaulo Zaukadaulo

1. Multi-source Data Fusion Algorithm

• Kusintha kwamphamvu pakati pa data ya mvula ya radar ndi data ya ground rain gauge
• Tekinoloje ya 3D yosinthira masinthidwe kuti muwonjezere kulondola kwa mvula
• Chitsanzo cha chenjezo cha Bayesian theory-based probabilistic chenjezo

2. Chenjezo la Threshold System

3. Kufalitsa Zambiri Zochenjeza

• Zidziwitso zokankhira za APP yam'manja (78%)
• Kuyambitsa makina owulutsira anthu ammudzi
• Zidziwitso za SMS (za anthu okalamba)
• Zosintha zolumikizidwa pamawebusayiti ochezera

IV. Zotsatira za Kukhazikitsa

1. Nthawi Yabwino Yochenjeza: Avereji ya nthawi yotsogolera yawonjezeka kuchoka pa maola a 2 kufika pa maola 6.5
2. Kuchita Bwino Kuchepetsa Masoka: 63% kuchepa kwa ovulala mu 2022 nyengo yamkuntho m'malo oyendetsa
3. Ubwino wa Data: Kulondola kowunikira mvula kwafika pa 92% (poyerekeza ndi makina a sensor imodzi)
4. Kudalirika Kwadongosolo: 99.2% chiwongola dzanja pachaka

V. Mavuto ndi Mayankho

1. Kupereka Mphamvu Zosakhazikika:
   • Machitidwe amagetsi a dzuwa okhala ndi supercapacitor mphamvu yosungirako
   • Kapangidwe ka masensa otsika kwambiri (<5W pafupifupi kugwiritsa ntchito)
2. Zosokoneza Pakulumikizana:
   • Multichannel automatic switching technology
   • Kuthekera kwa makompyuta (maola 72 osagwiritsa ntchito intaneti)
3. Zovuta Zosamalira:
   • Kudziyeretsa kachipangizo kachipangizo
   • Njira zowunikira za UAV

VI. Njira Zachitukuko Zamtsogolo

1. Kuyambitsa ukadaulo wa quantum radar pakuwunikira mvula pang'ono
2. Kutumizidwa kwa ma netiweki amadzi am'madzi acoustic sensor kuti azindikire zinyalala zomwe zikuyenda
3. Kukula kwa blockchain-based based certification system certification
4. Njira yotsimikizira deta ya "crowdsourcing" yogwirizana ndi anthu

Pulojekitiyi ikuwonetsa zotsatira za kuphatikizika kwa masensa ambiri m'makina ochenjeza za kusefukira kwamadzi, ndikupereka njira yofananira yaukadaulo yowunikira masoka m'maiko aku zilumba zotentha. Zalembedwa ndi Banki Yadziko Lonse ngati ntchito yowonetsera kuchepetsa masoka kudera la Asia-Pacific.

Seti yathunthu yamaseva ndi pulogalamu yopanda zingwe yothandizira, imathandizira RS485 GPRS / 4g/WIFI/LORA/LORAWAN

Kuti mudziwe zambiri zambiri
