Description

Technical Field

[0001] The utility model belongs to the technical field of single-lamp control of street lamps, and particularly relates to a single-lamp controller for street lamps that supports remote upgrade. Background Art

[0002] For the management method of traditional single-lamp controllers of street lamps: 1. The status of each lamp is different and the working status of the lamp cannot be known; 2. The management methods on different road sections may be different; 3. The management status of each lamp may also be different. Regardless of the problems in 1, 2, or 3, the status of the lamp cannot be viewed, and turning the lamp on and off is all manual management. There are many uncontrollable factors in manual operation, such as forgetting to turn the lamp on or off, not turning the lamp on or off on time, or even misremembering the location. Originally, the street lamps on this road were to be turned on, but the street lamps on other roads were turned on instead, resulting in the street lamps on the section that needed to be lit not being turned on, and the street lamps on the section that did not need to be lit being turned on, which also causes trouble for maintenance and greatly increases the labor cost.

However, once there is a fault in the internal software of the single-lamp controller of street lamps, when adding functions or modifying functions, professional personnel need to go to the site to remove the single-lamp controller and upgrade the software on site. If it is not fully realized after the upgrade, it is necessary to upgrade again on site, which greatly increases the labor cost, time cost, and management cost.

[0004] Therefore, how to realize the automatic detection of single-lamp street lamps is a problem to be solved at present. Content of the Utility Model

The status of each lamp is different and the working status of the lamp cannot be known. 2. The management methods on different road sections may be different. 3. The management status of each lamp may also be different. Regardless of the problems in 1, 2, or 3, the status of the lamp cannot be viewed, and the on-off of the lamp is managed manually. There are many uncontrollable factors in manual operation, such as forgetting to turn on or off the lamp, not turning on or off the lamp on time, or even misremembering the location. For example, when turning on the street lights on this road, the street lights on another road are turned on instead, resulting in the street lights on the section that needs to be turned on not being turned on, and the street lights on the section that does not need to be turned on being turned on, which also causes trouble for maintenance and greatly increases the labor cost.
