Traffic signal controlling machine for accurately alarming and photographing traffic jam and operation method thereof

Abstract

The invention relates to a traffic signal controlling machine for accurately alarming and photographing the traffic jam and an operation method thereof. The traffic signal controlling machine comprises a vehicle detector, a detecting signal analyzing and processing unit, a signal lamp drive unit, image acquiring equipment, a communication unit and the like, wherein the detecting signal analyzing and processing unit is provided with a green light signal input interface, a detection signal input interface of the vehicle detector and a traffic jam alarm signal output interface; the green light signal input interface is used for releasing a detected traffic direction; and the detection signal analyzing and processing unit is preset with a queue clearing period alarm threshold Ta and a green light driving period alarm threshold Tb. By using the method, the occupied condition of the vehicle detector can be monitored to Ta since the green lamp is lightened, a traffic jam alarm signal is transmitted if the vehicle detector is always continuously occupied; and after the Ta, the occupied condition of the vehicle detector can be monitored to the extinguishment of the light, the traffic jam alarm signal is transmitted if the continuous occupation of the vehicle detector is not less than Tb. The image acquiring equipment is started to photograph the field once when the traffic jam alarm signal is transmitted.

Description

technical field [0001] The invention relates to a traffic signal light control machine capable of accurately alarming and taking pictures of traffic jams in urban traffic management and an operating method thereof. Background technique [0002] Traffic lights play a pivotal role in modern urban road traffic management. At present, the commonly used traffic signal controllers at home and abroad can be divided into inductive signal controllers with vehicle detectors and timing signal controllers without vehicle detectors. The inductive signal control machine uses the vehicle detectors installed on urban roads as traffic detection means to detect the traffic flow of the road, and then the signal control machine calculates and generates the signal light timing scheme and executes it, or transmits the detection data of the vehicle detectors After arriving at the control center, the host computer in the control center calculates and generates a signal light timing scheme, and the...
