CN105722280A - Meeting prompt lamp for use at entrance and exit of underground garage - Google Patents

Abstract

The invention relates to a meeting prompt lamp for use at an entrance and an exit of an underground garage. The meeting prompt lamp is characterized by comprising a 12V direct-current power supply, two photosensitive circuits, a mono-stable delay circuit and a prompt lamp circuit, wherein a model of a time-base circuit IC1 in the mono-stable delay circuit is NE555. Entrance and exit passages of the underground garage are relatively narrow and small, causing great inconvenience in vehicle entering and exiting, especially causing greater inconvenience to unskilled fresh drivers, and particularly leading to scratches between vehicles entering and exiting at the same time. The above-mentioned problem can be solved well if an automatic device is adopted instead of staff to command vehicles to enter and exit according to a time sequence, namely, a driver who triggers the prompt lamp to start working firstly drives a vehicle into/out of the underground garage in priority while oncoming drivers consciously wait on a right side. According to the meeting prompt lamp for use at the entrance and the exit of the underground garage, ordinary electronic elements are built into the mono-stable delay circuit, so that the meeting prompt lamp can be started to work through triggering of vehicle lights.
