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

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.

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.

Traditional Solution vs ZHIYUAN

TraditionalZHIYUAN
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

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.
