1. Project background
In order to ensure the safety of passenger transportation and improve the efficiency of emergency response, my country's passenger stations, especially large passenger stations, have basically designed and installed digital video surveillance systems to monitor the distribution and behavior of passengers at key points such as ticketing areas, waiting areas, and platforms. Due to the small number of personnel in the station's comprehensive monitoring duty room and the large number of various operations (voice broadcasting, guidance information release, etc.), it is difficult to observe and monitor the numerous surveillance videos in real time for a long time.
Therefore, we urgently need to improve the function of the station monitoring system and the structure of vehicles, including the monitoring of the following key areas:
(1) Ticket sales area: real-time monitoring of the concentration of ticket buyers in each ticket office, and monitoring of passengers queuing to buy tickets at each ticket window The length of the team analyzes the video images of various leftovers and suspected items, and prompts the alarm.
(2) Waiting area: real-time monitoring of the passenger gathering degree in each waiting room or waiting sub-area, focusing on monitoring the passenger gathering degree of each entry ticket gate, can analyze the video images of various leftovers and suspected items, and prompt the alarm.
(3) Platform area: Real-time monitoring of the gathering degree of passengers on each platform, focusing on monitoring various illegally entering passengers or objects in the waiting yellow line and in the track area.
(4) Office area: Real-time monitoring of access to key office areas, including office areas such as income room, bill room, ticketing workshop, and comprehensive monitoring room. Analyze the behavior of important positions, and be able to prompt or warn behaviors such as leaving or sleeping.
2. Demand analysis
When communicating with a station information director recently, they wanted to build an intelligent transfer and diversion system for the ticket office. Mainly to solve the situation of mismatch between the station schedule and the use of the ticket window.
The main requirements are as follows:
1. You can view the queuing status of the ticket window;
2. If there are too many people in the queue, remind the arranging staff to increase the ticket window;
3. If there are too many empty windows, it is recommended to close some windows;
4. Passengers can go through the large screen Check the queue status at the ticket window for information such as the guide board.
3. Project construction
In response to the above needs, our company launched the EasyCVR intelligent security platform, matched with the corresponding intelligent algorithm, and obtained the result of the relevant video through the algorithm, and cooperated with the scheduling system and the voice broadcast system to feedback the relevant results to the corresponding personnel. And can save the video in real time. The EasyCVR system supports multiple protocol access, and can flexibly match third-party algorithms, and supports the output of related results to the business system through the API interface to achieve the integration of the entire system.
Implementation process:
1. Install video capture equipment at the ticket window;
2. Through configuration, connect relevant equipment to the EasyCVR platform through the corresponding protocol;
3. You can output the video stream to the algorithm server through configuration or call, and obtain the calculation result through the interface ;
4, the correlation results and corresponding to a video distribution service system through API interface;
5, showing service system according to the setting result.
Four, system function
EasyCVR video intelligent analysis and monitoring system is mainly divided into four major modules, namely: user management module, equipment management module, video monitoring module and video function module. The four modules work together on the intelligent analysis and diversion system of the station, which can manage all front-end network video servers and front-end monitoring equipment, and maintain the network connection with them; at the same time, it realizes authorization management for all users in the network, and all users You can log in to the server system through any computer, and monitor, query, and replay videos according to different permissions.
1. Real-time monitoring: Through the camera system, relevant personnel can understand the queue status of each ticket window.
2. Video structured and intelligent analysis: through the algorithm server, the window queuing situation is analyzed and collected.
4. System integration: The system can be converged to a business system for display through the API interface, realizing the integration of multiple systems.
5. Video access: The system supports cloud and local video recording, and the local or cloud video can be retrieved as needed.
6. Data cascading: Share videos to supervisory units through API, GB national standard and other protocols.
