Communication timer and learning timer are integrated into one. They can communicate in the learning state and learn in the communicating state. They can automatically convert each other online. Communication parameters can be modified in real time, which is convenient and simple.
Countdown digital display, controlled by a microcomputer, can automatically detect the time of traffic lights, built-in hardware and software watchdog circuit, stable and reliable work. Fine craftsmanship, beautiful appearance, light weight, surface spraying, outdoor matte black, dust-proof, waterproof, service life more than 10 years.
Characteristic:
1. The timer is a real-time learning and real-time communication integrated machine. It communicates with the signal through RS485 (or 422, 232) interface.
2. Communication Protocol: GA/T508-2004 Communication Countdown Communication Protocol (see Appendix A)
3. Display multi-phase data and maximize learning timing in a signal cycle:
(1) Section 2 Left Turn Green Lantern Time
(2) Two straight green light hours
(3) The time when the left-turn green light and the straight green light are on at the same time in Section 1
(4) 2 sections of red light time (when the left turn green light or the straight green light or the yellow light is on, the red light is not within the time range)
Arbitrary yellow light time
4. The display is intuitive and eye-catching. The display part adopts imported ultra-high brightness light emitting diode, which has stable performance, high uniformity and ideal display effect. Red, yellow and green display or red-green mixed color display.
5. Modular assembly is used to repair and replace parts quickly.
6. As long as you are in the learning state, you don't need another power supply to connect directly from the traffic lights.
