Overview
The ZYKX ZYKX-20 Portal-Type Infrared Thermographic Screening System is an industrial-grade, non-contact, real-time human temperature monitoring solution engineered for high-throughput entry screening in regulated and public infrastructure environments. It operates on the physical principle of passive infrared radiometry: all objects above absolute zero emit electromagnetic radiation proportional to the fourth power of their absolute (Kelvin) surface temperature—governed by the Stefan–Boltzmann law. The system employs a calibrated uncooled microbolometer sensor array optimized for peak spectral responsivity in the 8–14 µm atmospheric transmission window—fully encompassing the dominant thermal emission band of human skin (centered near 9.4 µm). Unlike spot pyrometers or handheld units, the ZYKX-20 integrates dual-axis thermal imaging with spatially registered optical guidance to automatically detect and measure facial or wrist surface temperature within a defined passage zone—without requiring subject cooperation, positioning aids, or operator intervention. Its design conforms to IEC 62471 (Photobiological Safety of Lamps) and complies with essential performance criteria outlined in ISO/TR 13154:2017 (“Medical electrical equipment — Guidance on the application of infrared thermography for fever screening”) for secondary triage support in mass screening applications.
Key Features
- Passive, non-invasive measurement: No emitted radiation; relies solely on detection of naturally emitted mid-wave infrared energy from human skin.
- Dual-zone targeting algorithm: Simultaneously identifies and prioritizes forehead and wrist regions using embedded computer vision, minimizing ambient reflectance interference and emissivity variability.
- Real-time thermal overlay with visual cueing: Integrated visible-light camera provides synchronized RGB feed overlaid with temperature-coded thermal contours and dynamic pass/fail indicators.
- Configurable thermal alarm logic: Programmable upper-threshold limit (default 37.3 °C), hysteresis control, and multi-level alert escalation (visual, audible, relay output).
- Environmental compensation engine: Onboard ambient temperature and humidity sensors feed real-time correction factors into the Planck-based radiometric calibration model.
- Modular mechanical architecture: Tool-free quick-connect frame system enables field deployment or reconfiguration in under 15 minutes without specialized tools or structural anchoring.
- IP54-rated enclosure: Dust- and splash-resistant housing suitable for indoor transitional zones (e.g., building lobbies, transport hubs, clinical anterooms).
Sample Compatibility & Compliance
The ZYKX-20 is validated for use with ambulatory human subjects across diverse demographic groups (age ≥3 years, height ≥90 cm). It does not require consumables, calibration standards, or routine optical alignment under stable environmental conditions. While not classified as a medical device per FDA 21 CFR Part 809 or EU MDR Annex XVI, it is intended for adjunctive, non-diagnostic fever screening only—consistent with WHO interim guidance (2020) and CDC recommendations for layered infection control protocols. The system supports audit-ready logging per GLP-aligned data integrity principles: timestamps, operator ID (optional), raw thermal matrix snapshots (16-bit), and processed temperature metadata are stored locally (SD card) with optional encrypted export via USB or Ethernet. Firmware adheres to IEC 62304 Class B software lifecycle requirements.
Software & Data Management
Embedded firmware v3.2+ includes a web-accessible configuration interface (HTTPS, TLS 1.2) supporting remote parameter adjustment, firmware updates, and log retrieval. Data export formats include CSV (tabular time-series), JPEG (annotated thermal overlays), and DICOM-SR (structured reporting for integration into hospital PACS or facility management systems). Optional cloud gateway module enables TLS-secured MQTT transmission to centralized dashboards with configurable retention policies (30–180 days). All temperature records include cryptographic hash signatures to ensure immutability during regulatory review. Audit trail functionality meets ISO 13485:2016 clause 7.5.10 and aligns with FDA 21 CFR Part 11 electronic record/electronic signature (ER/ES) expectations when deployed with identity-authenticated user accounts and role-based access control.
Applications
- Frontline screening at transportation nodes: airport international arrivals halls, seaport passenger terminals, rail transit gateways, and bus depots—where throughput exceeds 500 persons/hour.
- Clinical facility ingress points: emergency department triage corridors, outpatient registration zones, and vaccination clinic queues—reducing direct clinician exposure during initial contact.
- Educational and occupational settings: university campus entrances, K–12 school gates, manufacturing plant access checkpoints, and large-scale event venues requiring pre-entry health verification.
- Regulated infrastructure: government administrative buildings, correctional facilities, and long-term care residences implementing mandatory wellness surveillance protocols.
- Temporary deployment scenarios: mobile field hospitals, disaster response staging areas, and humanitarian aid distribution centers requiring rapid, scalable thermal assessment capability.
FAQ
Is the ZYKX-20 certified as a medical device?
No. It is classified as a Class II industrial thermographic screening system under Chinese GB/T 38711-2020 and is not intended for clinical diagnosis, treatment, or replacement of clinical-grade tympanic or temporal artery thermometers.
What environmental conditions affect measurement reliability?
Accuracy degrades if ambient temperature falls below 10 °C or exceeds 40 °C, or if relative humidity exceeds 85 % RH with condensation risk. Drafts, direct sunlight on the sensor lens, or reflective surfaces within the passage zone must be mitigated per installation guidelines.
Can the system integrate with existing access control hardware?
Yes. Dry-contact relay outputs (NO/NC) and Modbus RTU over RS-485 enable interoperability with turnstiles, barrier gates, and building management systems (BMS) without proprietary middleware.
How often does the system require recalibration?
Under normal indoor operating conditions, factory calibration remains valid for 12 months. An annual verification using a NIST-traceable blackbody source (±0.1 °C uncertainty) is recommended for compliance documentation.
Does the device store personally identifiable information (PII)?
No. By default, only anonymized thermal metadata (timestamp, temperature value, pass/fail flag) is retained. Facial images are not stored unless explicitly enabled via opt-in consent mode compliant with GDPR Article 9 and CCPA Section 1798.100.
