Unattended during nights and holidays
Temperature anomalies in cold storage and server rooms often occur at night or on holidays. By the time manual inspection discovers them, materials and equipment are already damaged.

Temperature Alarm & Monitoring System
Multi-point real-time temperature acquisition, instant over-limit alerts with AI trend anomaly detection
Solution Overview
Real-time multi-point temperature data acquisition with multi-sensor support, automatic over-limit alerts. AI trend analysis detects slow temperature anomalies. Historical curve query, data export. Widely used in server rooms, cold storage, workshops, and warehouses.

Problems Solved
Unreliable manual logging
Paper-based logging has long intervals and is prone to omissions, making it impossible to reconstruct temperature change processes afterwards and hard to assign accountability.
Only seeing instantaneous thresholds, missing drift
Slow temperature creep that hasn't crossed a threshold goes undetected, yet the trend already points to issues like compressor degradation or defrost anomalies.

Alert MethodFixed threshold alerts: only fire at limit crossings, blind to slow degradation. A single fault floods dozens of useless alerts, burying real risks.AI time-series anomaly detection: learns each device's baseline, catches slow drift and hidden anomalies. 80% fewer false alarms, alerts routed to the right people.
Notification & ClosurePhone calls/group chat: alerts dumped in chat, who handles what? Night alerts buried, discovered next day.WeCom/SMS graded push + work order automation: graded, person-specific routing. Unacknowledged alerts auto-escalate. Full traceability: alert → work order → resolution → archive.
Integration & RetrofittingCostly retrofit & downtime: new monitoring needs rewiring, equipment swap, production stoppage — long cycle, lost output.Reuse existing sensors, plug & go live: compatible with 95% DTUs/sensors. MQTT/Modbus standard protocols. No production line changes — 30-minute data integration.
Data ValueReal-time only, no history: manual logs capture instant values only — no trend visibility, can't replay fault evolution.Time-series database + history replay: massive long-term storage, any-range curve playback with work order records to reconstruct full fault picture and continuously improve O&M strategy.
Key Features
Multi-channel concurrent acquisition
Single device supports multiple temperature probes, second-level reporting, real-time web refresh.
Graded threshold alerts
Three-tier thresholds (warning / alarm / critical), supports time-slot and zone-specific settings.
AI temperature trend analysis
Learns historical operating curves, identifies slow drift and periodic anomalies, and provides early risk signals.
Probe and device anomaly detection
Short circuit, open circuit, stuck value, or acquisition device offline — each triggers a separate alert to avoid false sense of normality.
Historical curves and export
Any time range historical curve playback, supports report export for audit and handover.
Multi-channel alert push
Web dashboard, WeCom, and SMS reach on-duty personnel, with escalation and acknowledge/clear support.
Data Collection & Alerting Specs
Collected Data
- Multi-point temperature values
- Probe status (short/open/disconnected)
- Device online status and signal strength
- Alert events and acknowledgment records
Alert Types
- Temperature above/below limits
- Abnormal rate of temperature rise
- Slow trend drift
- Device offline
- Probe fault
Alerts pushed to Web dashboard and WeCom; SMS as optional add-on. Same-type alerts auto-merged for noise reduction.
Deployment & Billing
- Deployment
- Reuse existing temperature probes and third-party DTU acquisition boxes. Connect to the platform via MQTT or Modbus-RTU/TCP — no modification to existing refrigeration or HVAC equipment needed.
- Billing
- Licensed by number of temperature monitoring points. Supports single-project buyout and annual subscription models.
FAQ
Can already-installed probes and DTUs be used directly?
Most existing probes and DTUs can be connected directly. The platform interfaces via standard protocols (MQTT attribute reporting / Modbus registers). We provide a point table template before connection — once register and range are confirmed, it goes live.
Who alerts during network or power outages?
Acquisition devices report heartbeats at fixed intervals. If no report is received beyond the agreed duration, an offline alert triggers. UPS power can cover common outage scenarios and avoid blind spots.
How long is historical data retained?
Data is stored in a time-series database. Raw and aggregated data are retained per subscription plan for long-term trend analysis and fault review, exportable at any time.
