The led traffic barricade lights need for continuous real-time monitoring terminal for data collection, monitoring buoy working conditions at any time, so that after failure to instantly alert. Collection frequency should ≥1 / min.
Regularly send data
Monitoring data terminal to be sent to the central station this time every once in a while, so this time the monitoring center be able to monitor the status of aids to navigation work, timed transmission interval set by the monitoring center.
Answer feature
Beacon monitoring terminal can receive the query instruction. Timely send data to the monitoring center.
Automatic alarm function
When the automatic setting range is determined, when abnormal or buoy data collected beyond the set range, immediate initiative to automatically send an alarm message:
(1) buoy beyond the displacement range (10 m, 20 m, 30 m, such as adjustable) terminal can active judge and automatic alarm, maximum drift beyond the scope of the police, the ship sailed beyond the scope of the police. Automatic tracking alarm can be saved and playback historical track, easy to retrieve lost beacon.
(2) supply undervoltage, overvoltage alarm (alarm thresholds can be set and modified).
(3) Flash abnormal alarm (flash mode or light quality false alarm).
(4) led barricade lightst emitting abnormal alarm (such as daytime lights glow at night without light, insufficient number of available light bulbs, etc.).
Above alarm is judged by the monitoring terminal active alarm, and the alarm information is sent to the monitoring center, through sound, image and other tips on duty, or on duty notification via SMS.
Background monitoring center can also monitor and control terminal timeout, a communication error, etc. alarm.
Power-saving sleep function
Monitoring terminal after sending or receiving data monitoring center instruction automatically enter power-saving sleep state, in power-saving sleep state monitoring terminal current is less than 20MA, while ready to receive inquiries, remote settings, command control center and immediately wake up.
Detection circuit in the power-saving sleep state has been in working condition, displacement drift, impact, can immediately wake beacon lights when abnormal or parameters overrun monitoring terminal host to the monitoring center sends alarm information.
Remote control function
Remote monitoring terminal capable of receiving instructions from the central station, according to the directive or other facilities for navigation mark corresponding control
