Abstract: A guard route security method and a computer readable storage medium are provided. The method includes receiving positioning information of a security guided vehicle and generating a security guided vehicle track; searching a low-position camera and a high-position camera around the security guided vehicle according to the positioning information, and feeding back searching information; and turning on the high-position camera to trace and monitor the security guided vehicle according to the searching information. According to the guard route security method, the security guided vehicle is shot and monitored at a high-position camera monitor to achieve a follow-up control of the security guided vehicle with the high-position cameras, which is convenient for the security guards to quickly learn the surrounding environment and carry out security work for guard route more intuitively and effectively.

Abstract: A video map engine system includes a configuration management client, multiple video equipments, a video access server, an augmented reality processor, and an augmented reality client. The parameters of the video equipments includes azimuth angle P, vertical angle T and zoom factor Z of the video equipment, the augmented reality client is adapted for calculating the location where the augmented reality tag is presented in the real-time video according to the values of P, T, Z and the target location carried by the augmented reality tag, and presenting the augmented reality tag on the corresponding location of the real-time video. Therefore, the real-time video is served as the base map, and the augmented reality tag is presented on the base map, thereby achieving a video map effect.

Abstract: A system and method for testing a network-side harmonic component of a motor train unit, the method comprising: detecting a current of each power unit, sampling and quantifying the detected current, acquiring a digital current signal of each power unit, superimposing each digital current to obtain a current of the entire train, and acquiring a harmonic component according to the current of the entire train. A sample frequency is determined according to a frequency and a target phase angle error of the harmonic component to be detected. The provided system and method for testing the network-side harmonic component of the motor train unit improve a detection accuracy of harmonic current and can detect the harmonic component at a frequency above 3000 Hz.
