Answers to questions about smart street light controllers

How is the smart street light control system composed?

   The system mainly consists of a host computer and a single-lamp controller. The power carrier module inside the single-lamp controller is used to communicate with the host through the power line. The collected voltage and current signals of each point are sent to the host, and the host passes through it. GPRS is transmitted to the server to learn about the situation of each smart street lamp and perform unified deployment control.

   The working and control principle of single lamp controller?

  Single lamp controller is installed in the bottom or top lampshade of each lamp pole. Responsible for controlling the power of single or multiple smart street lamp heads and the switch of each lamp head. Collect operating data and upload it to the host in the concentrator by means of power line carrier. It is mainly composed of ATMAL32 single-chip microcomputer, carrier module and control module. Each single light controller has a unique address, which corresponds to the number of the light pole. Therefore, the location of the controller can be easily located through the GIS map of the monitoring center. Therefore, the corresponding operation of the single lamp controller at the main station can realize various energy-saving controls such as turning on every other, turning on every second, extinguishing the lamp holder of the slow lane, and reducing the brightness in the middle of the night.

  The transmission principle of the smart street light control host?

   Each transformer cabinet only needs to install one communication host. Mainly responsible for collecting fault or status information and reporting it to the monitoring center. And according to the order of the monitoring center to perform switch lights and dimming operations. Among them the microcontroller uses the STM32F103 chip of the ARM7 series. Run the UCOS2 operating system, which mainly completes the packaging and processing of the smart street lamp status or fault data transmitted from the carrier. Complete the processing of information such as the current measured by each branch, and assemble the processed data and send it to the main station monitoring center through the GPRS module, and obtain the data remotely.

  The principle of controlling via mobile app?

   The server side is mobile phone information, and then directly transmits the data to the monitoring center to connect. The monitoring center is the center of operation, maintenance, processing, statistics, analysis and supervision of the entire smart street lamp monitoring system. The monitoring center communicates with the server through GPRS or other networks, and issues maintenance or control commands to the communication host to query measurement data, branch status or single lamp status, etc.
