Description

street light remote controller

technical field

The utility model relates to a street lamp control device, in particular to a street lamp remote controller.

Background technique

In recent years, my country's urban road lighting devices have developed rapidly along with economic growth. However, there are still many problems in street lamp control:

1. It does not have remote time calibration, setting the time of switching lights and forced switching of lights: it cannot calibrate the time error of the clock control in time, and it cannot remotely modify the time of switching lights according to the actual situation.

2. It does not have the emergency function of remote forced switch lights: it cannot be forced to switch lights in time according to the needs of actual conditions, such as major reception tasks, foreign visits, sudden changes in weather, and holidays.

3. No fault remote alarm function: the existing management of lighting facilities mainly adopts the manual inspection mode, and the workload is heavy. The failures are mainly based on reports from inspectors and complaints from citizens. Lack of initiative, timeliness and reliability, real-time, accurate and comprehensive monitoring of the operation status of street lights in the city is not possible. The lack of an effective failure warning mechanism also wastes manpower, material resources and financial resources. .

4. Does not have real-time monitoring and monitoring functions: Urban street lights and street lights cover a large area. If the management methods are backward, it is impossible to accurately detect faults such as cable theft, line leakage, open circuit, mistakenly turning on lights during the day, turning off lights at night, and power failures. Once the above situation occurs, it will inevitably bring huge economic loss and personal injury, and affect the normal life of citizens at the same time.

5. It cannot feed back the working status information of the lighting facilities, and cannot remotely automatically control, monitor, etc. The number of street lamps in cities continues to increase, and there are fewer street lamp management personnel, which will inevitably increase the maintenance workload. According to the current maintenance method, it is difficult to ensure normal lighting and timely processing of faults.

6. It is impossible to carry out remote centralized monitoring and management of the night scene landscape project that the government has made great efforts to build, which makes it difficult to light up the night scene as a whole and cannot reflect the night scene effect of the entire city.
