Problems solved by technology

[0003] Compared with the verification process of general instruments, the verification of the fixed-installation red-light recording system has the following characteristics, which makes the realization of the verification special. The red-light automatic recording system is generally fixedly installed at highway intersections and traffic arteries, and the system or sensor generally cannot be disassembled. Laboratory verification cannot be carried out, but the on-site verification of traffic intersections is faced with the traffic of motor vehicles, the site situation is complicated, and it is difficult to obtain the verification data stably

Embodiment 2

[0034] This embodiment relates to the verification method of the verification device of the red light automatic recording system described in Embodiment 1, comprising the following steps:

[0035] The first step is to select the verification test lane, adjust the position of the LED display unit in the display module according to the photo evidence collection requirements of the red light automatic recording system installed at the intersection controlled by traffic signals, turn on the test host and the analog trigger power supply, and the LED display unit Display the current time and the current location information of the simulation trigger;

[0036] In the second step, the central processing module sends a trigger command to the analog trigger, and the analog trigger sends a trigger signal to trigger the photo function of the red light automatic recording system to take pictures, and to perform false trigger and anti-interference detection when the green light and yellow li...

Embodiment 3

[0040] Such as figure 2 As shown, in this embodiment, on the basis of Embodiment 1, the trigger module is set as a motor vehicle 1, the GPS antenna is adsorbed on the roof of the motor vehicle 1 to receive GPS signals, and the test host is arranged in the cab of the motor vehicle to automatically detect the red light. Record the verification method of the system, including the following steps:

[0041] The first step is to select the verification test lane, adjust the position of the LED display unit 2 on the motor vehicle 1 according to the requirements of the automatic red light recording system installed at the intersection controlled by traffic signals, and adjust the position of the LED display unit 2, and turn on the test host. The LED display unit 2 displays the current Time and current position information of the analog trigger;

[0042] In the second step, motor vehicle 1 running a red light triggers the photo function of the red light automatic recording system to ...

Abstract

The invention relates to a calibrating device for an automatic red light running recording system, in particular to a calibrating device and method for the automatic red light running recording system. The device comprises a main testing machine, a display module and an analog trigger. The display module receives instructions sent by the main testing machine and displays corresponding information such as current time, the vehicle speed and positional information, and meanwhile the main testing machine can control a trigger module to send a trigger signal of a ground sense coil to replace the function that a motor vehicle triggers the ground sense coil to trigger the photographing function of the automatic red light running recording system, so that the safety coefficient is high; in the calibrating process, the analog trigger is directly placed above the road surface ground sense coil, the main testing machine sends the trigger instructions to the analog trigger, the trigger module sends the trigger signal to trigger the photographing function of the automatic red light running recording system, and corresponding errors are calculated after measurement is conducted multiple times. The calibrating device is simple in structure, convenient to use, high in adaptability, and capable of guaranteeing detection and recording uniqueness of a red light running recorder.

Description

technical field [0001] The invention relates to the technical field of verification of an automatic recording system for running a red light, in particular to a verification device and a verification method for an automatic recording system for running a red light. Background technique [0002] As the number of motor vehicles increases year by year, road traffic is facing great pressure. Safety and efficiency have become important issues of intelligent transportation. The act of running a red light has just become an important illegal act to be dealt with in safe traffic. The automatic recording system for running a red light is also widely used. In this way, whether the recorded data of the automatic red light recording system is credible and whether the recording efficiency meets the needs has become a problem that the metrology department needs to face. "GA / T 496-2009 General Technical Specifications for Red Light Automatic Recording System" puts forward general requir...
