MONITORING CHART
We evaluate the effectiveness of the proposed SSL by simulation of abnormal states of street lamps based on fog computing server which implements flexible management platform. We analyze the periodic maintenance of abnormal states of street lamps. The results of SSL reliability; and finally, the energy conservation has been solved.

CONTROL ROOM SURVEILLANCE
The server will check the abnormal states, the server will automatically send the information on abnormal lamp state consisting of street lamp ID, lamp location, and abnormal state description to the managers and nearest serviceman.
Therefore, the maintenance period can be decreased seriously. The managers can send commands using mobile application or Web browser. Therefore, the serviceman can receive the tasks through mobile application or SMS.

STREET LIGHT INFORMATION
The Smart Street Light SSL consists of three main parts: an intelligent sensing street lamp, which can adjust lamp brightness, an autonomous alarm which reports about abnormal behavior; an efficient network, which is used for real-time communication between managers and massive street lamps; and lastly, a flexible management platform, which is easy and highly automated.

RECEIVING STREET LIGHT STATUS
Using both the intelligent sensing street lamps and efficient network, the server gets the information of all street lamps, consisting of lamps states, locations, external environment brightness, and so on. Therefore, the management platform is a key factor of the street lamp management system. Here, we implement a flexible management platform based on fog computing, which simplifies the management system. Moreover, the fog computing based server offers better real time response, while cloud computing delivers the elastic computing power and storage at a lower cost.
As already mentioned, all street lamps periodically send information of their states to the server, and the server stores received information in the database. In order to find the abnormal states of street lamps, the server periodically checks.

MONITORING POWER DETAILS
The check cycle can be set by managers. The longer the check cycle is, the longer the maintenance cycle of a broken street lamp is, and the lower the system cost is. Contrary, the shorter the check cycle is, the shorter the maintenance cycle of a broken street lamp is, and the higher the system cost is. 20 minute can be tolerable for both maintenance cycle and system cost. Therefore, to balance these two sides, we set the check cycle to 20 minutes, i.e. server checks states in database every 20 minutes. can conclude that the light bulb may be broken.

• Intimate Status
By the location sensors in the street lamp, the server can be informed whether the street lamp is stolen.
Moreover, the street lamp can be found when the street lamp is lost. Further, when the server finds the light bulbs of street lamps are broken, the server can send the detail location to the serviceman for repairing, so the serviceman can locate the broken street lamp accurately which improves efficiency.

MANAGE POWER ADJUSTMENT
In intelligent sensing street lamp, the brightness of street lamp can be adjusted with flexible management platform, the management platform can optimize resource scheduling for easy and highly automated management. The street lamp is equipped with some sensors, such as location sensor, infrared sensor, and light sensor, to form an intelligent sensing street lamp. Consequently, brightness of street lamps can be adjusted.
The infrared sensor in street lamp makes the street lamp more intelligence. The street lamps can distinguish the demands for brightness. Namely, for street lamps in the unmanned area, the brightness should be turn down, and for the street lamps in the crowded area, the brightness needs to be turned up. Therefore, safety in the crowded areas can be guaranteed, and turning down of unmanned street lamps meets energy conservation requirement.

AUTO ABNORMAL ALERT
The abnormal states are: 1. The street lamp bulb is broken. When server checks the street lamp and finds its current is equal to zero but its voltage differs from zero, it concludes the street lamp has a broken bulb.
2. The street lamp is offline. When server checks the street lamp and finds that no data are received from the lamp, it concludes the street lamp is in offline state.
3. The street lamp is in the power saving mode. When server checks the street lamp and finds both its current and voltage are lower than their normal values, it concludes the street lamp is in the power saving mode.
4. Fault. When server checks the street lamp and finds that both lamp current and voltage are equal to zero, and all street lamps in that region have the same state, the server concludes that a fault occurred, which may be caused by a power failure.
5. Close. When server checks the street lamp and finds that both lamp current and voltage are equal to zero, but not all street lamps in that region have the same state, the server concludes that the street lamp is closed.
Autonomous alarm is to avoid stealing. Every street lamp needs to have a self-protection ability. When it is stolen, it should autonomously send the alarm. In this way, the street lamp stealing can be avoided. A flexible management platform is implemented, and it notifies the managers about broken street lamps at real time and automatically dispatches the maintenance staff to repair broken street lamps.
