Abstract

The invention relates to an early-warning system based on stroboscopic information. The system comprises a sensing unit, an optical transmit-receive unit and a control unit. The sensing unit comprisesan optical modulation module and sensors. The optical modulation module is used for modulating an electrical signal carrying monitoring information sent by the sensor into an optical signal comprising at least two light-emitting phases in a light-emitting period, wherein at least one monitoring information is set in a manner of modulating luminescence time length, characteristic curve and / or spectral change rules of light in at least one light-emitting phase, and at least one monitoring information, light intensity / brightness of which is approaching to zero candela change, is set in a mannerof modulating luminescence time length, characteristic curve and / or spectral change rules of light in at least one light-emitting phase; and when at least one monitoring information in the optical signal received by the at least one optical transmit-receive unit is in an early-warning state, the control unit sends an early-warning instruction to the at least one optical transmit-receive unit andcontrols the at least one optical transmit-receive unit to project a guide light pattern corresponding to the safety level to indicate a safe route.

Description

technical field

[0001] The invention relates to the technical field of information early warning, in particular to an early warning system based on stroboscopic information. Background technique

[0002] In the safety monitoring system, the most basic and most important function is to monitor the dynamic changes of the analog data at the monitoring point in real time, to give an alarm when the preset alarm value is reached, and to report to the security when the preset alarm value is reached or exceeded. The monitoring system sends out a control signal, so that the security monitoring system sends out an alarm sound, and an alarm window pops up at the terminal of the security monitoring system for alarming.

[0003] For example, in a factory production environment, dedicated wiring is required for early warning systems. When the sensor detects that a certain monitoring value exceeds the standard and prepares for an early warning, the line between the sensor and the controll...
