Description

Technical Field

[0001] This utility model relates to the technical field of electrical control, and in particular to a multifunctional circuit control system. Background Technology

[0002] With urban development, intelligent control is becoming increasingly prevalent in daily life. Building smart cities and achieving smart living is the development direction of modern towns.

[0003] Cities have a large number of streetlights, which constitute the densest urban infrastructure and urgently require the establishment of a remote control platform for streetlight management.

[0004] As the most densely and evenly distributed information infrastructure in cities, streetlights are considered an excellent carrier for 5G base station outdoor coverage. Driven by smart city development and 5G base station construction, they will gradually transform from a single lighting function into a new type of public infrastructure. Smart streetlights, based on road lighting poles (i.e., light-controlled lamps), integrate multiple poles into one, reducing the number of poles on the road and freeing up public space resources. Simultaneously, as an important carrier for smart city construction, smart streetlights will serve as a port for the Internet of Things, playing a greater "integrated" role.

[0005] In related technologies, electrical control systems are one of the key technologies for street light management. Smart street lights collect environmental information through sensors, and people remotely send control commands to control the smart street lights by combining environmental information and lighting needs through a pre-configured control platform. Electrical control systems are usually composed of separate modules, such as power supply modules and communication modules. Due to the dispersion of modules, they are large in size, have complicated wiring, and have low integration.

[0006] Among the aforementioned technologies, the communication module suffers from poor scalability and a limited number of interface types supported by the system, while the power module suffers from high energy consumption due to its power conversion circuit. Utility Model Content

The microcontroller sends the processed data to the host computer through the communication module. The host computer sends the control command to the microcontroller through the communication module. The microcontroller generates the corresponding control signal according to the control command and sends it to the slave computer.

[0021] The metering chip is used to determine whether the current signal output by the isolation sampling unit meets the preset standard. If it does not meet the standard, the corresponding fault signal is sent to the microcontroller. The microcontroller sends the fault signal to the host computer via the communication module for the staff to read.

[0022] Optionally, if the lower-level machine includes a light-controlled lamp, then the control core module further includes a dimming unit.
