Lane solar traffic light
Lane lights are composed of green arrow lights and red fork lights, which are set on variable lanes and only work on this lane. When the green arrow light is on, vehicles in this lane are allowed to pass in the indicated direction; when the red fork light or arrow light is on, vehicles in this lane are prohibited from passing.
crosswalk solar traffic light
Pedestrian crossing solar traffic light consists of red and green lights. There is an image of a standing person on the red light mirror surface, and a walking person image on the green light surface. Pedestrian crosswalk lights are located at both ends of the pedestrian crosswalk at important intersections with a large flow of people. The head of the lamp faces the roadway and is perpendicular to the center of the road.
Pedestrian crosswalk light signals have two kinds of signals, green light and red light, and their meanings are similar to those of intersection signal lights, that is, when the green light is on, pedestrians are allowed to pass through the crosswalk; You can continue to pass or wait at the centerline of the road. ,
command solar traffic light
The waving signals are divided into straight ahead, left turn and stop signals. When vehicles and pedestrians encounter light signals, traffic signs or traffic markings that are inconsistent with the command of the traffic police, obey the command of the traffic police.
Light control machine for traffic signal
main feature
Multi-MCU, modular design, compact and reasonable structure, easy maintenance and function expansion
It adopts international standard industrial fieldbus and has strong environmental adaptability
Set up a completely independent pure hardware system monitoring circuit to ensure long-term reliable operation of the equipment
Conventional communication can be compatible with optical fiber and telephone line; it can also expand the network communication mode of TCP/IP protocol according to the demand
The main function
(1) Networked real-time coordinated control: By connecting with the communication machine of the command center, two-way real-time data transmission is realized; the signal machine can report various traffic parameters and working status on the spot in time; the central control system can issue control commands in real time to carry out remote synchronization remote control
(2) Remote setting of operating parameters: The central control system can download various optimized control schemes to the signal control machine for storage in time, so that the signal control machine can operate according to the scheme formulated by the command center even in the independent operation state.
(3) Automatic downgrade processing: It has automatic downgrade processing function under abnormal conditions such as communication abnormality or interruption.
(4) On-site modification of operating parameters: the control scheme and parameters can also be modified on-site through the control panel, or directly input and modified by connecting a laptop computer to the serial interface.
(5) Cable-free self-coordination control: Relying on the built-in precision clock and optimized scheme configuration of the device, it can realize cable-free self-coordination control without system or communication interruption.
(6) Traffic parameter collection and storage: After configuring the vehicle detection module, it can report the status of the detector in real time and automatically collect, store and transmit traffic parameters such as traffic flow and occupancy rate.
(7) Single-point induction control: In the independent operation state of the signal machine, semi-induction or full-induction control can be performed according to the detection parameters of the vehicle detector.
(8) Period-divided and variable-period control: In the independent operation state of the signal machine, control according to different dates, time-divided periods, and variable period is realized according to the multi-period control scheme present in the signal machine.
(9) On-site manual control: Manual step control or manual forced yellow flash control can be performed at the intersection through the control panel.
(10) Other control methods: by expanding the corresponding interface modules and detection equipment, special control methods such as bus priority can be realized.
