WARNING SYSTEM FOR DETECTING APPROACHING OBJECT AND METHOD THEREOF
20210016810 · 2021-01-21 ·

A warning system for detecting approaching object and method thereof are provided. A detection unit detects a moving path of the approaching object; a storage unit stores a warning information including the warning area and the confirmation condition; and a processing unit receives the detection signal provided by the detection unit to acquire the current moving path of the approaching object. When the approaching object is detected as moving in the buffering zone, the confirmation operation of the confirmation condition is activated. When the moving path falls in the warning area and fulfills the confirmation condition, the processing unit sends out a warning signal. Therefore, a potentially dangerous approaching object is accurately identified, and the warning is correctly sent.

RAILROAD CROSSING SAFETY ASSEMBLY
20200398877 · 2020-12-24 ·

A railroad crossing safety assembly includes a plurality of object sensors that is each positioned on a respective one of four corners of a railroad crossing. The object sensors emit a sensing signal across the railroad crossing to detect an obstruction on the railroad crossing. A data storage unit is provided and each of the object sensors is in electrical communication with the data storage unit. The data storage unit is in electrical communication with emergency responders thereby facilitating the emergency responders to be notified of the obstruction on the railroad crossing. Additionally, the data storage unit is in communication with a railway operation department thereby facilitating the railway operation department to alter railway scheduling in response to the obstruction.
