Des écoles qui voient venir les dangers.

Les écoles se trouvent en zone inondable, en zone sismique ou sous la chaleur estivale, et elles abritent les populations après les catastrophes. Des capteurs à l’école, reliés aux alertes nationales et aux exercices de l’établissement, donnent au personnel des minutes pour agir, montrent quels bâtiments vérifier et permettent de garder les écoles ouvertes en sécurité.

1. Éducation · Écoles sûres

   Places that must stay safe

   Schools sit on floodplains, in earthquake zones and under summer heat, and after disasters they often shelter the whole community. The school safety framework asks for safe buildings, school disaster management and drills, and minutes of warning at the school itself can protect hundreds of children.

2. Ce qui est mesuré

   Shaking, water and heat

   A strong-motion sensor fixed to the building records shaking. A gauge on the nearest stream or drain measures rising water, and sensors in classrooms and yards measure heat, so each school sees its own hazards rather than a regional average.

   Instruments

   Strong-motion sensor · Flood gauge · Heat sensors

3. Le nœud de base

   Alerts the school can use

   The node detects strong shaking and reports where building checks are needed, raises flood and heat alerts against thresholds agreed with the district, relays national warnings to school displays and records every drill and response. Nothing is lost when a link drops; the node keeps it.

4. Radio et liaisons

   Independent of the school network

   Alerts and data travel over cellular, independent of the school network, so they work when it fails. A gauge on a stream away from the school reaches it over a low-power link. Each link is chosen for the place, not from a catalogue.

   Réseau mobile public · LoRaWAN

5. Comment ça marche

   From a rising drain to a safe dismissal

   Heavy rain falls during the school day. The drain gauge beside the school climbs past its threshold; staff receive the alert and follow their plan, holding students on the upper floor and dismissing them by the safe route once the water falls.

   Scope with the district

   The scope reads the district’s schools, hazards, school safety plans and warning arrangements. Nexus Observatory Inc. returns the school kit, alert design, drills support and a price per school and per year. Every assumption in the scope is written down and priced.

7. De la commande à l’exploitation · Relevé

   Survey each school

   Crews visit each school with its safety lead: building type, nearest stream or drain, hot rooms and yards, assembly points and alert displays. Findings are recorded with photographs. Every finding is kept with the site record for the crews who follow.

8. De la commande à l’exploitation · Autorisations

   School and authority approval

   The school, district and disaster authority approve the kit and alert rules, and families are told what alerts mean. Every approval is kept with the school record. Approvals are tracked site by site, so nothing waits unseen. No crew goes to site before its approvals are in place.

9. De la commande à l’exploitation · Fabrication

   Build and test

   Kits are assembled, calibrated, nodes enrolled with their identities and configured with thresholds and warning links. Each kit runs before it ships. Test results travel with the kit to the site. Nothing ships until the whole kit has passed its tests together.

   Ouvrir le configurateur de stations

10. De la commande à l’exploitation · Installation

    Install and mark

    Crews fix the shaking sensor to the building structure, install the flood gauge and heat sensors, mount alert displays and connect backhaul. Every part is photographed and recorded. The site record is updated before the crew leaves. Crews follow the site safety plan throughout the work.

11. De la commande à l’exploitation · Mise en service

    Commission with a drill

    Chaque nœud prouve son identité. Sensors are checked against references, alerts are tested to displays and phones, and the school runs a drill with the system. Response times are recorded. Results are signed and kept with the site record. Acceptance is recorded with the owner before handover.

12. De la commande à l’exploitation · Exploitation

    Protect and recover

    Staff receive alerts and act on their plans; after shaking, the district sees which schools need building checks; in heat, outdoor activities change; and every event and drill is recorded. Reports for owners and funders come from the same record.

13. De la commande à l’exploitation · Maintenance

    Drill every term

    Drills are repeated each term, sensors checked and recalibrated on the agreed plan, thresholds reviewed after events, and software updated in rings. Every change is kept with the school record. Spares and procedures travel with the crews. Maintenance history stays with each site for its whole life.

14. Produits de données

    For staff, districts and authorities

    School staff receive hazard alerts; district facility teams receive building check lists after shaking; teachers and coaches receive heat guidance; education and disaster authorities receive drill and event records, each tied to school and time. Each product carries its site, time and quality flags.

15. Preuves

    Safe schools, on record

    The kit supports the comprehensive school safety framework and the safe schools call of the global disaster risk framework, flood levels follow hydrological practice and heat the WMO guide. Every alert, drill and event is kept with the school record.

01Le lieu et ses dangers

Où il fonctionne, et ce qui peut mal tourner.

Operating contextThe comprehensive school safety framework sets out safe facilities, school disaster management and risk reduction education, and the global disaster risk framework calls for safe schools. Flood levels are gauged to hydrological practice and heat is measured to the WMO guide.

Dangers

• Floods that reach schools with students inside
• Earthquakes that damage buildings unseen
• Heat that makes classrooms unsafe
• Warnings that never reach the school
• Schools used as shelters without checks
