Embodiment Construction
[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0028] Such as Figure 1-3 As shown, the single-chip microcomputer of the present invention collects the frequency signal of the reference oscillator and the ground sense coil in the working state in real time; wherein the frequency of the reference oscillator is fixed; according to the need to extend the red light, select the ground sense coil that needs to be in the working state Coil;
[0029] When there is road congestion in a certain straight direction and the device needs to be activated, select the ground induction coil of the straight lane in this direction as the working state; in the working state of the ground induction coil, if the vehicle can pass the ground induction coil before the end of the green light in the straight direction area, the preset scheme of the original signal light will not be changed; if the vehicle fails to pass throug...

The invention discloses a sense coil type red lamp delayer and a method thereof. The sense coil type red lamp delayer comprises a vehicle detector device and an inductive control type semaphore device; the vehicle detector device comprises a sense coil set, a tuning circuit, a reference oscillator and a single-chip microcomputer; the sense coil set is laid under a road surface of an intersection;the sense coil set is connected with the tuning circuit; the single-chip microcomputer is connected with the tuning circuit and the reference oscillator separately; the single-chip microcomputer is connected with the inductive control type semaphore device; most structures of the sense coil type red lamp delayer adopt the existing device, and the intersection does not need to be largely modified.Once a fault happens at any link from the sense coil to a transmission feeder line, the semaphore can be operated in a fixed timing control mode under the condition of function degradation, and reliability is high.
Description
technical field [0001] The invention relates to a road traffic ground induction coil type red light delayer device and a method thereof, belonging to the technical field of road traffic control devices. Background technique [0002] At some intersections, there is a phenomenon of vehicles grabbing green lights. That is, the vehicle crosses the stop line in the last few seconds of the green light and continues to drive, but stays at the intersection due to congestion in this direction or the vehicle is too long to completely leave the intersection within 3 seconds of the yellow light. Vehicles in the turning direction are blocked, and the congestion in one direction may further aggravate the congestion in multiple directions. Article 53 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" stipulates: "When a motor vehicle encounters a traffic jam at an intersection ahead, it shall stop outside the intersection one by on...
