Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of tunnel electromechanical control, and particularly relates to a tunnel electromechanical control system and method based on digital twinning. BACKGROUND

[0002] The statements in this section merely provide background information related to the present application and do not necessarily constitute prior art.

[0003] When driving into a tunnel, the driver will appear "blind" due to the change in light intensity, and cannot see the situation near the tunnel entrance at the first time. This phenomenon is called "black hole effect" and "white hole effect". The so-called "black hole effect" is that when the driver drives into the tunnel, the pupil will quickly enlarge suddenly from bright to dark, and the eye cannot adapt at once, and it will feel a black hole. At this time, the tunnel entrance is like a black hole. When coming out of the tunnel, it is just the opposite, the light suddenly changes from dark to light, and the pupil quickly shrinks. The human eye sees a white light, which is called "white hole effect". Therefore, the tunnel entrance and exit are the road sections with many accidents, especially in good weather, the "black hole effect" and "white hole effect" are particularly serious, and there is a great traffic safety hazard. In order to avoid the "black hole effect" and "white hole effect" as much as possible, the electromechanical equipment such as tunnel lighting is indispensable.

[0004] The tunnel electromechanical equipment is the main energy consumption end of the tunnel engineering in the operation stage, and is also an important equipment to ensure the normal passage of the tunnel. The inventor finds that the current tunnel light control system mostly sets the brightness according to the time period and the sunlight intensity, and the dimming strategy is relatively fixed, which is not flexible in dealing with the "black hole effect" and "white hole effect", and is not conducive to energy saving and emission reduction. The tunnel ventilation control system, the signal lamp control system and the lighting control system are often independently set, the management is scattered, and it is not conducive to the unified operation and management of the tunnel.
