Supply Networked Signal Controller

Signal to high-performance 32-bit ARM microcontroller core, embedded software operating environment using real-time multitasking operating system to ensure stable and reliable system. Using solid-state switches, photoelectric conversion control signal isolation technology, stable operation, with a total of 36 independent motor vehicle road lights drive output, 12 independent non-motorized vehicles lights output, 8 independent person lane light output. Flexible network communications system, one can use the cable, telephone line transmission, support TCP / IP protocol Ethernet networking; the second is General Packet Radio Service GPRS, 3G data transmission terminals communicate command center and traffic control unit. Variety of communication interfaces: RS-232/485, Ethernet port. Signal control mode, one can operate the remote command center monitoring software configuration signal at the junction; the second is to use a laptop and a special touch to the scene to set up the man-machine terminal. Multiple time periods and multiple program configurations can be set 16 hours a day, 16 kinds of timing, 255 sets of control scheme, and another special day (holidays, weekends) 16 sets of independent control program. User-friendly control panel for ease of operation and use, real-time simulation display traffic light controlled intersection conditions, traffic control process, dedicated Secret Service manual operation panel. Data parameter storage: Use the most current clock chip and data storage devices, effective parameters, power-down is not lost for 10 years shows, power-down, the clock can operate normally for 10 years. Manual control degradation function: a yellow flash key, a key to all red, manual steps. No cable support coordinated control (green wave realization), in the absence of communication links between the signal case, according to the school when the GPS clock synchronization is achieved by setting the phase of each traffic signal coordination control, green wave coordination. Wireless remote control, electronic compass orientation and wireless data radio to achieve automatic vehicle Secret VIP function, complete special release function intersection. Bus Priority (BRT) function, traffic signal processing based on a variety of programs conducted mode signal priority request, it is possible under the premise of protecting the public transport priority, so that society can successfully pass the vehicle traffic lights, no congestion. Pedestrian crossing control: according to press the pedestrian button to send a request signal requesting achieve coordinated control pedestrian crossing the road. Induction control: a half-induction, all sensing, by traffic detectors, collected traffic information, the traffic flow status, real-time adjustment corresponding traffic parameters to suit changes in traffic control.
