Abstract
Provided is a digital wireless radio traffic signal lamp group which comprises more than one digital wireless radio traffic signal lamp equipped with a digital wireless radio signal receiving device. Usually, a digital wireless radio traffic signal lamp group is arranged at a crossing. The digital wireless radio traffic signal lamp comprises a master control circuit, a storage device, an input output interface, software, and traffic signal lamps. The digital wireless radio traffic signal lamp is characterized by comprising a digital wireless radio receiving device and a traffic signal lamp instruction detecting module. The traffic signal lamp instruction detected by the detecting module is used for changing the display status of the traffic signal lamps by appointment.
Description
Technical field
The utility model relates to digital radio broadcast traffic lights cohort.
Background technology
Existing a kind of timer-operated traffic lights, because cycle cycling time and the first parameters such as clock starting point of setting have arbitrariness and internal clocking drift, the state of its traffic lights has randomness.This on average is higher than 0.5 so that driving runs into the probability of red parking.If can use computing machine to feed back the real-time control program that forms traffic lights according in the past traffic and scene, and connect each automatic traffic signal light by the digital radio mode real-time communication, make the switching of signal lamp reveal maximum close friend to the meter for vehicle that travels, then might under existing traffic route hardware condition, make the unimpeded rate of driving on average improve 20% even more.
Summary of the invention
The purpose of this utility model is that digital radio broadcast traffic lights cohort will be provided.
The technical scheme in the invention for solving the technical problem: with more than one with the digital radio broadcast traffic lights of digital radio broadcast signal receiving device, form a digital radio broadcast traffic lights cohort.A common cross road mouth arranges a digital radio broadcast traffic lights cohort.The digital broadcast signal lamp is comprised of governor circuit, memory device, I/O Interface, software, traffic lights.The digital broadcast signal lamp contains a digital radio broadcast receiving device and contains signal lamp command detection module, is used for changing the show state of traffic lights according to agreement by the signal lamp instruction of described detection module detection.
The beneficial effects of the utility model: adopt artificial intelligence automatically to work out the intelligent signal lamp scheme, and utilize the transmitted signal lamp instruction of digital radio broadcast system to realize traffic lights are controlled, help to realize the optimum automatically control of traffic lights, than by adopt wired mode or adopt man-to-man wireless mode carry out the signal link cost low, take the wireless channel resource and lack, implement to make things convenient for; Mode strong anti-interference performance than artificial antenna broadcasting; Reliability improves whole system because the circuit junction that relates to makes less, each digital broadcast signal lamp interchangeability is strong.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic diagram of a digital radio broadcast traffic lights cohort.
1. digital broadcast signal lamps among the figure; 2. digital radio broadcast transmitting station; 3. main control computer.
Embodiment
Fig. 1 provides an embodiment of the present utility model.
Among Fig. 1, a crossroad, arrange one by four digital radio broadcast traffic lights with the digital radio broadcast signal receiving device, be called for short digital broadcast signal lamp 1, a digital radio broadcast traffic lights cohort of composition.Digital broadcast signal lamp 1 is comprised of governor circuit, memory device, I/O Interface, software, traffic lights.Digital broadcast signal lamp 1 contains a digital radio broadcast receiving device and contains signal lamp command detection module, is used for changing the show state of traffic lights according to agreement by the signal lamp instruction of described detection module detection.Digital broadcast signal lamp 1 is by digital radio broadcast transmitting station 2 and main control computer 3 wireless connections that the signal lamp instruction is provided.
