Example Embodiment

[0020] Example one

[0021] Please refer to figure 1 A calibration method of automatic recording system time based on Internet-based implementation of red light, including steps:

[0022] S1, the Internet of Things terminal acquires red light automatic recording system, standard clock, and camera data, and generates first data to the cloud platform;

[0023] Step S1 is specifically:

[0024] The Internet of Things terminal acquires red light automatic recording system, standard clock, and all red light data recorded in the preset time, and generates the first data to the cloud platform.

[0025] Specifically, the red light automatic recording system, the standard clock, and the camera data are communicated with the IoT terminal, respectively;

[0026] Also included with traffic light signals, the traffic light signaling machine communicates with the Internet of Things;

[0027] After the traffic light signal is transmitted, after the synchronous trigger signal, the system time of ...

Abstract

The invention provides a method for calibrating the time of a red light running automatic recording system based on the Internet of Things, and the method comprises the steps that the data of the red light running automatic recording system, a standard clock and a camera are obtained through an Internet of Things terminal, first data is generated, and the first data is transmitted to a cloud platform; the cloud platform performs extraction according to the received data to obtain red light running time data and intersection information; the cloud platform judges whether the current traffic light state is effective or not according to the red light running time data and the intersection information, and if so, the time error is calculated; and the cloud platform generates a verification report according to the time error, and calibrates the time of the red light running automatic recording system according to the verification report, so that field calibration is realized, and the safety and the accuracy are high.

Description

technical field [0001] The invention relates to the technical field of calibration, in particular to a calibration method for automatically recording system time for running a red light based on the Internet of Things. Background technique [0002] The on-site system time calibration method of the red light automatic recording system is based on GA / T496-2014 "General Technical Specifications for the Red Light Automatic Recording System": the red light automatic recording system works continuously for 24 hours, compares the system timing with the standard timing, and calculates the error. The automatic recording system for running a red light is installed outdoors. During the on-site calibration, the standard clock is required to be on site continuously for 24 hours. It is difficult to carry out on-site calibration. The specific disadvantages are as follows: [0003] (1) On-site calibration requires the traffic police department to close the detection area; [0004] (2) Low ...
