The subway platform lights are always on. These lights are set to same brightness as it is inconvenience to manually adjust the brightness based on the existence of the people. A current solution is provided to change the brightness of a certain area, for example, DALI (Digital Addressable Lighting Interface) dimming commands may be sent to a group of lights to adjust the brightness of the area.
In a subway station or train station, for the empty area (for example, platform of suburb's station) , lights need to be always on without knowing the chance of taking off passengers.
There is a possible way to control the light in empty area by using PIR (pyroelectric infrared) sensor. For example, when a door of a train is open, there is a passenger taking off the train, the PIR sensor may detect the passenger, and send the signal to a controller, which may send DALI dimming commands to a driver to control the brightness of the light.
In one example, the light in empty area may work in an energy-saving mode under which the brightness of the light is about 40%of normal brightness, when the PIR sensor detects a passenger taking off the train, the controller may control the driver to drive the light to 100%of normal brightness.

As shown in Fig. 1, a system 100 for controlling lighting equipment includes a prediction apparatus 10 and a controller 20.
The prediction apparatus 10 is configured to detect a passenger Po with tendency to take off a train carriage 201, according to a picture captured inside the train carriage 201. For example, the picture may be captured by a camera 202 inside the train carriage 201.
The controller 20 is configured to generate a controlling signal Cs according to a detecting result of the prediction apparatus 10. In at least one embodiment, the controller 20 may be clod server.
The controlling signal Cs is used to control a driver 30 to drive a lighting equipment 40 in a predetermined area 50 of a station. The predetermined area 50 may be an area near a door 2012 of the train carriage 201 when a train 200 arrives at the station.
When there is at least one passenger Po with tendency to take off the train carriage 201 being detected, the controlling signal Cs sent by the controller 20 controls the driver 30 to dim brightness of the lighting equipment 40 up to a predetermined level before the train 200 arrives the station.
According to the first aspect of the embodiments, a passenger with tendency to take off a train carriage can be detected according to pictures captured inside the train carriage, the detected result will be used to control a light equipment at a station, therefore, the light equipment will turn brighter before the train arrives at the station.
As shown in Fig. 1, the prediction apparatus 10 includes a prediction unit 101. The prediction unit 101 is configured to detect the passenger Po with tendency to take off the train carriage 201 by using artificial intellectual (AI) graphic identification algorithm, and generate a first signal S1 according to the detecting result. In one example, the artificial intellectual (AI) graphic identification algorithm may be skeleton-based action recognition algorithm, by which a person with certain action or gesture in the picture will be recognized. As for the working principle of the prediction apparatus 10, related art may be referred to get more details.
In at least one embodiment, the prediction unit 101 detects the passenger Po with tendency to take off the train carriage 201, according to the passenger Po in a first area 2011 near a door 2012 of the train carriage 201.
For an example, when the passenger Po is standing in the first area 2011, the prediction unit 101 determines the passenger Po having tendency to take off the train carriage 201.
For another example, when the passenger Po is standing in the first area 2011 and performing predetermined action, the prediction unit 101 determines the passenger Po having tendency to take off the train carriage 201. The predetermined action may be carrying a bag, and/or carrying a suitcase, and/or facing the door 2012, and/or moving towards the door 2012, etc.
In at least one embodiment, the size of the first area 2011 may be fixed. The location of the first area 2011 may be changed according to information which indicates which door will be open after the train 20 arriving at the station. For example, when the information indicates a right door will be open at the station, the prediction unit 101 will change the first area 2011 to a location near the right door of the train carriage 201; when the information indicates a left door will be open at the station, the prediction unit 101 will change the first area 2011 to a location near the left door of the train carriage 201.
In at least one embodiment, the prediction unit 101 may start the detecting at a predetermined moment before the train 200 arrives at the station. The predetermined moment may be several seconds (for example, 3 seconds) before the train 200 arrives at the station. For example, the train 200 or a server (not shown) may broadcast signal, to notify the train 200 will arrive at the station; the prediction unit 101 may start the detecting when receiving the broadcast signal, or the prediction unit 101 may calculate the moment to start the detecting according to the received broadcast signal.
