In industrial environments, equipment failures or parameter anomalies (e.g., high temperature, current overload, abnormal pressure) require immediate notification to maintenance personnel. Traditional SCADA systems rely on network connectivity, where interruptions may cause delayed alerts. The ARM industrial computer, functioning as an SMS and 4G alarm controller, ensures fast and reliable delivery of alarm notifications, meeting real-time monitoring needs.
Front-End Data Acquisition
Collects sensor and PLC data via Modbus RTU/TCP and RS485/IO interfaces.
Common monitoring points: temperature, pressure, smoke, water leakage, access control, and power status.
ARM Industrial Computer ARMxy Series (Alarm Controller)
Equipped with a 4G communication module and SIM card for stable connectivity.
Executes local alarm logic: threshold detection and state linkage.
Supports dual-channel alarming:
SMS: Sends alerts directly to designated phone numbers.
4G Network Push: Uploads alerts via MQTT/HTTP to cloud platforms or messaging apps (e.g., WeChat, Whatsapp).
Alarm Notification
Upon triggering alarm conditions, the ARM industrial computer instantly sends SMS to maintenance personnel.
Simultaneously uploads alarm data via 4G to the cloud for access via backend systems or mobile apps.
Dual Assurance: SMS ensures delivery even during 4G network outages, preventing missed alerts.
Edge Intelligence: Local logic processing reduces dependency on cloud infrastructure.
Multi-User Notifications: Configurable to notify multiple maintenance personnel.
Multi-Interface Support: Supports RS485/RS232, DI, DO, relays, AI, AO, RTD, TC, pulse counting, and PWM output, accommodating diverse industrial scenarios.
Scalability: Supports relay linkage for triggering audible/visual alarms or power-off protection.
Low Power & High Reliability: Ideal for unmanned environments like power distribution rooms, data centers, and factory workshops.
Power Distribution Rooms: Alerts for current overload or power outages via SMS.
Data Center Monitoring: Real-time notifications for HVAC failures or temperature/humidity anomalies.
Pump Stations/Pipelines: Automatic alarms for high water levels or low pressure.
Factory Equipment: Immediate alerts for abnormal temperature or pressure in production lines.
Building Security: SMS/4G alarms for unauthorized access or smoke detection.
