What are the two types of latitude and longitude controllers for street lamps?

Street lamp warp and weft controller: Street lamp warp and weft controller can be divided into two types: one is networked (remote controller FAC4) and the other is independent (ET2 warp and weft timer). The remote controller FAC4, through the monitoring center and remote distributed RTU(FAC4) and with the help of the powerful GPRS/CDMA mobile communication network, completes four functions of remote control, remote monitoring and remote real-time dynamic management (telemetry) of municipal street lamps, which are referred to as "four remote functions" for short: remote control: remote control of the switch of street lamps; Telemetry: Remote measurement of all electrical parameters of street lamp distribution cabinet and single lamp electrical parameters (single lamp monitoring function); Remote communication: equipment fault information and self-diagnosis information are automatically transmitted back in real time! It is convenient for the management department to deal with it in time; Remote adjustment: dimming and energy saving can be realized through resonant frequency. ET2 latitude and longitude time controller can control the switching time of 1-3 loop by using three modes: timing control, latitude and longitude control and timing+latitude and longitude time control. Using advanced embedded microcomputer control technology, according to the changing law of four seasons and the principle of the earth's rotation around the sun, any region in the world has a unique latitude and longitude, and the sunrise and sunset time of this region can be calculated, and it can be revised and adjusted to meet the needs of different geographical environments. Street lamp latitude and longitude controller is the best energy-saving control device for street lamps, landscape lamps, advertising light boxes, neon lights and other equipment, which can be widely used in streets, railways, stations, waterways, schools, power supply departments and other application places that need time control. Features of remote controller FAC4: the average power saving rate is 10%- 15% (centralized monitoring). GPRS wireless communication can be networked or work independently. The maximum number of analog input points is 3 ~ 65,438+03, digital input points are 6~20 and digital output points are 3~20. All IO points can be dynamically displayed on the graphic interface of the upper computer in real time.
