Safety Helmet Impact Tester

     MOEORW‑W6820M1 is an in‑house engineered test instrument dedicated to verifying protective capabilities of industrial safety helmets. It executes two core assessment procedures: impact‑absorption evaluation and anti‑penetration check, aligning with national and power‑sector regulatory criteria including GB/T 2812, GB/T 2811, DL/T976‑2017 and DL/T1476‑2023.

    Built around a Linux‑based ARM embedded computing platform, this tester integrates high‑accuracy force acquisition hardware plus motor‑driven height tuning modules. Operators interact via capacitive touchscreen, accessing real‑time impact‑force curve visualization, multi‑level audible‑visual alarm outputs and embedded thermal print output. The unit delivers consistent readouts with robust anti‑interference performance over its 5‑year design lifespan. It fits helmet‑maker QC workshops, power‑industry safety‑tool laboratories and third‑party inspection institutes, facilitating product compliance audits and cutting routine‑test overhead.

    Physical cabinet‑door locking interlocks block test initiation when access panels remain open. Prior to releasing falling weights or piercing cones, multi‑step confirmation pop‑ups plus countdown reminders prevent operator bodily harm. All measured datasets get stored locally; LAN‑enabled upload supports centralized filing and traceable audit trails for every completed trial.

Precision‑grade Force‑sensing Assembly High‑stability force transducer delivers measurement tolerance within ±0.5 %. At 1.333 MHz sampling rate, the system renders dynamic force‑time curves instantly, capturing peak‑force and acceleration‑related datasets throughout impact episodes.

Motor‑driven Height Adjustment with Laser‑guided Alignment Elevation mechanism tunes drop height within 1000±12.5 mm. Cross‑hair laser markers pinpoint contact spots between falling probes and helmet crowns, eliminating human‑operated positioning deviations.

Simplified Touch‑centered Operation 7‑inch capacitive touch‑panel UI bundles four functional zones: impact‑test workflow, penetration‑test workflow, parameter configuration and historical‑record lookup. Hardware push‑buttons are minimized for streamlined manipulation.

Multi‑tier Operator Safeguard Architecture

• Cabinet‑door interlock: test sequence stays disabled when door is ajar
• Dual‑popup confirmation plus 3‑second countdown together with acoustic prompt before probe release
• Extended buzzer alert triggers for penetration‑test failure status

Complete Dataset Archiving & Output Options Every test log and plotted curve is preserved within local database. On‑board thermal printer generates one‑click hard‑copy test‑result reports. Local‑area‑network communication pushes measurement records toward external lab‑management platforms for long‑term archiving.

Robust Embedded Industrial‑grade Control Linux‑ARM industrial framework avoids Windows‑originated malware threats. Upper‑lower computer decoupling delivers strong electromagnetic‑interference immunity, suitable for non‑stop lab‑site operation cycles.

User‑friendly Maintenance Layout Detachable test‑chamber housing and smooth non‑stick outer surfaces simplify cleaning. Dedicated printer compartment facilitates thermal‑paper replacement. Standard‑spec 2A fuse is easy to swap; fault‑diagnosis prompts surface directly on screen for quick troubleshooting.

Compact Integrated Cabinet Layout Mobility‑enabling lock‑mount casters support relocation and stable anchoring. Internal storage compartments house impact hammer, piercing cone and anthropomorphic head‑forms, conserving lab‑floor footprint.

• Cabinet door interlock protection: test locked when door open;
• Double confirmation pop-up window + 3-second countdown + sound reminder before releasing hammer/cone;
• Long-time alarm sound for unqualified penetration test to remind operators.
