Loop status monitoring and equipment self-maintenance: support online upgrade firmware, built-in real-time clock chip, when the concentrator power supply is cut off, the clock can be maintained for more than 10 years, the data can be maintained for more than 30 years, when the power supply is restored, the saved data is not lost. Port expansion function: support concentrator port expansion, reserved with 3 isolation relay outputs, 3 analog inputs, 3 digital inputs, 1 RS-485 interface input (support MODBUS-RTU protocol), 2 pulse meter inputs, etc. Through these extended interfaces, the concentrator can detect various sensor inputs, such as light sensors, temperature and humidity sensors, PM2.5 sensors and meters, etc., and can also control external high-power AC contactors to achieve sub-loop control of lamps. The single lamp controller interface is reserved for the centralized controller, which can be connected with each single lamp controller through power carrier technology to realize the monitoring and control of single lamp and the timing control function. In the centralized controller, the loop control part and the reserved single lamp control part adopt modular design, and the loop control and single lamp control mode can be realized by replacing the module. 2. Lamp controller The lamp controller is installed at the lamp and used in conjunction with the centralized control host. ROLA spread spectrum technology is adopted to realize single-lamp level control by controlling the host to receive instructions from the monitoring center. It has the following functions: single lamp voltage and current power monitoring, switch lamp, dimming, single lamp status monitoring, equipment self-maintenance. In order to achieve single lamp networking, control energy saving, power data acquisition.

Centralized control mode

Each group can be controlled separately to realize any configuration of loop output attributes to achieve high efficiency and energy saving. The centralized control mode includes 6 working modes: timing control, customized weekly control, comprehensive control and manual control. No matter what mode the central controller works in, the device can be automatically restored to the state before power failure after accidental power loss and recovery.
Single lamp control mode
Newell intelligent lighting control system realizes communication with single lamp controller through ROLA wireless MESH, and users can monitor the switch and dimming of each lamp and various electrical parameters. The controller has five built-in single-lamp control modes: group control, group control, inter-control, point control and manual control. Regardless of the mode of operation, the device can be automatically restored to the state before the power failure after the accidental power loss is restored. At the same time, two groups of switch lamp time and two groups of energy-saving time can be set to realize single lamp control and time-sharing energy saving.
