System functions
○ Real-time monitoring:
System real-time monitoring of the residual current and temperature of each loop, and in the main interface shows the details of the contents of the circuit name number and various types of function buttons.
○ Alarm setting and prompt:
The system supports the remote current and temperature alarm values and various loop information and status of remote settings. When the loop alarm occurs, the system sends out sound and light alarm signal, while the interface sends significant color change, and automatically record the details of the order of events, event record retention ≥ 24 months, million trace.
○ Alarm and fault record:
The system is equipped with a dedicated historical database, providing historical alarm records and historical fault records. Users can access, query and print at any time through the report interface. Advanced users can delete the records one by one or all.
○ Alarm printing:
Monitoring equipment is equipped with micro-printer, can automatically / manually print the alarm, fault information. Supports automatic printing of information by setting the interface to alarm / fault occurrence.
○ Historical Data Trend Curve:
System for the history of the residual current and temperature data, support the curve of the query, query time interval and loop can be dynamically set. The interface can reflect in real time the surplus electric current or the temperature range of change in any period of time.
○ Status information display:
The system can display the current status information (power status, equipment failure status, alarm status and working status of all current communication devices) in real-time and keep in sync with the monitoring device indicator.
○ System failure self-test:
Real-time display of internal monitoring function of the functional module and has a fault self-diagnosis function, while real-time display system fault causes, and real-time regional probe to determine the state of communication, the entire system failure intelligent self-test.
○ user classification management:
The system is divided into three levels of authority management, different operations need corresponding permission level to be operated, in order to prevent misoperation and illegal entry.
○ System operation information:
The system has a separate information window, record all the running information of the equipment since the start and run, and then judge the current state of the running system.
System structure
SMGTR electric fire monitoring system uses equipment layer, communication layer, the management of three-tier distributed design, decentralized control, centralized management.
For regional monitoring of large-scale regional multi-level monitoring equipment can be cascaded to achieve the operation and set the system and sub-regional display, alarm.
For small and medium-sized regional monitoring using a single monitoring device to achieve the overall monitoring system, the installation area of the detector signals all sent to the monitoring equipment, centralized processing, centralized display, alarm and management, the system cost-effective.
Scope of application

Working principle
Electric fire monitoring detector real-time monitoring of low-voltage power distribution system in the live wire to ground fault generated residual current and distribution box or cable temperature to determine the cause of electric fire hazards and early warning.
When the power distribution circuit is in normal operation, the loop current through the residual current transformer (LF) current vector sum is zero (regardless of the circuit inherent leakage current), the residual current value is zero, and the temperature in the normal working range, detector (SMGTR ) Running in the monitoring state.
When leakage occurs in the circuit, the real-time residual current value is monitored by the detector (SMGTR) by the residual current transformer (LF) current vector sum is not zero. If the residual current value is greater than the set protection value, the detector sound and light alarm signal, and through the release (K) automatically cut off the fault circuit power supply. The detector (SMGTR) monitors the temperature of the circuit in real time through a temperature sensor (PT). When the circuit temperature is abnormal, the detector (SMGTR) monitors the temperature value is greater than the set protection value, the detector sound and light alarm signal, and through the release K automatically cut off the protection line power, thereby reducing and reducing electrical fires To ensure the safety of life and property, electrical fire detectors can be connected to the fieldbus electrical fire monitoring equipment to achieve multi-loop centralized monitoring.
