Intelligent lighting control problem answers

How is the smart lighting control system composed?

　　 The system mainly consists of a host and a single-lamp controller, which form the power carrier module inside the single-lamp controller. It communicates with the host through the power line, and sends the collected voltage and current signals of each point to the host, and the host passes through it. GPRS is sent to the server so as to know the situation of each street lamp and carry out joint distribution control.

　　 The working and control principle of single lamp controller?

　　Single lamp controller is installed in the bottom or top lampshade of each pole. It is used to control the power supply of single or many 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 only an address, which corresponds to the number of the light pole. Therefore, it is easy to locate the position of the controller through the GIS map of the monitoring center. Therefore, the corresponding operation of the single-lamp controller at the master station can complete 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 at night.

　　The transmission principle of the intelligent lighting control host?

　　 Each transformer cabinet only needs to install one communication host. It is mainly responsible for collecting shortcomings or situation information and reporting it to the monitoring center. And can perform switch lights and dimming operations in accordance with the instructions of the monitoring center. In the meantime, the microcontroller uses the STM32F103 chip of the ARM7 series. Run the UCOS2 operating system, which mainly completes the packaging and processing of the street lamp situation or defect data transmitted from the carrier. Finish the processing of information such as the current measured by each branch, and assemble the processed data and send it to the monitoring center of the master station through the GPRS module, and obtain the data through long distance.

　　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 the operation, protection, processing, calculation, analysis and supervision of the entire street lamp monitoring system. The monitoring center communicates with the server through GPRS or other networks, and issues protection or control instructions to the communication host to query measurement data, branch road conditions or single lamp conditions, etc.
