The simple control method is to control the night lighting of a single building, usually using a 'switch control module' to control the power supply of outdoor lighting fixtures (or to control the power supply of contactor wire packages, and then the contactor to control the power supply of high-power lighting fixtures), coupled with the use of a 'timing module', Enable the control system to automatically call up different lighting effects, or 'turn on mode', based on pre-set times (such as weekdays, weekends, holidays, major holidays, etc.)< br /> From the perspective of lighting effects, the night scene lighting of a single building can be controlled by simple power on/off of the lighting fixtures (using switch control modules such as DR0820), or it can be a complex LED large screen lattice effect. Animation files, video files, and even the content captured by the live camera head in the computer can be processed by professional LED control software and sent to various LED lighting fixture points through the control commands of the DMXs, And control the brightness/color of each LED point. This control system can also be remotely triggered and controlled by the 'City Light Control Center', which sends the desired effect command wirelessly to control the LED control system of a designated individual building to display the desired animation effect.

The advanced approach is to incorporate the night lighting control system of a single building into the overall unified control system for urban lighting (usually the lighting office or street lighting office in each city is the control center). In this case, a 'MP-GPRS' wireless module that can accept wireless control commands sent by the' City Night Lighting Control Center 'should be installed in the control box of a single building¡® The MP-GPRS wireless module maintains connection with the designated Alibaba Cloud server after accessing the internet through 3G/4G; Receive wireless control commands from the lighting control center through Alibaba Cloud servers; The computer or Android phone in the lighting control center (currently not supporting iOS phones) can log in to the Alibaba Cloud server program through a web browser to remotely monitor the current status of the lighting circuits of various building units, and can remotely control the intelligent control modules inside the control box of each unit (such as DR0820CU/DR1220/DR0420, etc.). The intelligent control module executes specific control commands such as turning on, off, dimming, and changing color.

After adopting 'Alibaba Cloud Control' technology, the entire network structure is: mobile phone/computer mobile end - Alibaba Cloud server - individual control box< br /> A mobile phone can become a lighting control center, monitoring lights, receiving status alarms or warranty requests from Alibaba Cloud servers, and even reading the current detection value of the lighting circuit.

The following is the Alibaba Cloud software monitoring interface for the lighting control system of a certain racecourse, as shown in the following figure (real-time display of circuit status and module communication status):
The six control boxes of the racecourse are distributed throughout the racecourse, and each control box has a 'MP-GPRS' wireless module connected to Alibaba Cloud< br /> Red indicates poor communication conditions (some may have poor signal through mobile network), while green indicates good communication< br />
