The Wuhan-Guangzhou high-speed railway has operated 5 accidents in 40 days. The Beijing-Shanghai high-speed rail just operated for 10 days has also experienced a breakdown recently. Although these failures all resulted in casualties, high-speed rail security has become the focus of people's attention. The high-speed rail accident has caused people to worry about the safety of high-speed rail. Well, today Xiaobian brings you together to understand the security equipment on the high-speed rail, so that everyone has a bottom:
High-speed railway security monitoring equipment
High-speed rail video surveillance requires special and high thresholds. The need to adopt advanced video surveillance technology, based on the IP network of the railway system, to build a digital, intelligent, distributed network video surveillance system to meet the public security, safety supervision, passenger transport, scheduling, vehicle services, maintenance, public works, telecommunications, Various requirements such as vehicle and power supply business departments, disaster prevention monitoring, rescue and emergency management, and emergency management have enabled the sharing of video network resources and information resources. The use of high-speed rail monitoring is divided into four aspects:
1, comprehensive video surveillance
The integrated video surveillance system as a subsystem of the communication service network in the communication system is responsible for the key stations, including the inter-vehicle railroad section, communications, signal room, traction power supply, power supply room, outside the monitoring;
2. CCTV monitoring
The CCTV monitoring system serves as a subsystem of the passenger service system in the information system, and implements image surveillance in the waiting rooms, platforms, entrance halls, squares in front of the station, and entrance throats. The CCTV monitoring system only configures front-end equipment, back-end display equipment, video servers, video storage equipment, and video management equipment, all of which are considered by the integrated video surveillance system.
3, room monitoring
The monitoring of the engine room mainly includes power environment monitoring and safety monitoring. It will use temperature-sensing and heat-sensing detectors and access control systems; unattended substations and lighting and other important power distribution equipment will be monitored and monitored in a timely manner to understand the operation of the equipment.
4, disaster prevention safety monitoring
Disaster prevention and safety monitoring can remotely understand and respond to emergencies such as storms, mudslides, floods, and traffic accidents in a remote way; transmit emergency video wireless video transmission to control centers for emergency command and dispatch
High-speed rail security alarm detection equipment
High-speed railways must conduct comprehensive monitoring of various possible disasters (such as strong winds, heavy rain, heavy snow, earthquakes, and other natural disasters as well as landslides, rockfalls, and foreign invasions), and establish safety early warning systems and emergency disaster relief systems. There are generally the following alarm devices on high-speed rails:
1, smoke monitoring alarm
The whole train is non-smoking and trains have sensors. If a passenger smokes cigarette smoke, the sensor senses it and the driver knows there is smoke in the compartment and then chooses a suitable place to park.
2, train speed alarm
The train speed sensor is installed at the bottom of the train and can accurately capture the train speed. When the train exceeds a certain limit speed, the network control system can alarm in real time and the driver needs to adjust the operating speed immediately.
3, bearing overheating alarm
The temperature sensor of the train monitors the bearing. Once the temperature is too high, the network control system will immediately report an alarm to prevent the bearing temperature from being locked too high, so as to avoid the accident of the vehicle crash.
4. Foreign objects set up monitoring and alarm system
In the sections where there may be idlers entering high-speed railways and where rockfall may occur, metal protection nets, foreign material monitoring networks, and monitoring and alarm systems are installed to ensure that the infringed information is transmitted to the comprehensive dispatching center in time and the operation of the train is controlled.
5, rainstorm added camera sensors
Rainfall meters are installed in areas with an annual rainfall of more than 200 mm, and three-level rainfall warnings are set up to implement measures such as warning, speed limit, and outage. In places where necessary, additional cameras, inclinometers, strain gauges, detection nets and other sensors were added to monitor subgrade disasters.
6, the earthquake automatically cut off the contact network power supply
After the earthquake, the railway seismic monitoring system will analyze and judge the monitored seismic signals in time. If the pre-warning level is reached, the power of the contact network of the relevant section will be automatically cut off, and the train running on this section will be stopped by the ATC signal, and the train running in the adjacent section will no longer enter the disaster area.
7, set the wind speed detector
Wind speed detectors need to be installed along the railway lines. These detectors are generally installed in super-large bridges, stations, substations, and tuyere areas. When strong winds are detected, the trains need to be immediately controlled.
High-speed rail security access control equipment
The high-speed rail access management system is mainly used for the unified monitoring and control management of passing passengers, access doors of station equipment management areas, offices and equipment management rooms, and communication equipment rooms along the railway line, and can pass through the system in the event of a fire. Inter-zone linkage function to achieve regional unlocking function to facilitate the evacuation of relevant personnel to escape, at the same time can also be used for railway staff attendance automated management, improve the operating unit's administrative level.
1, automatic ticket checking equipment
In the automatic ticket gate machine, an independent express card processing module is added to complete the process of checking the ticket transaction of ExpressCard. The fast-passcard processing module completes the card transaction flow according to the instructions and returns the result to the automatic ticket gate. Finally, the automatic ticket checking system realizes the functions of fast-passcard swiping, inbound check-in, check-out, check-out, ticket upload, information download, and statistics.
2. Entrance security inspection equipment
Mainly include security inspection machines, X-ray security inspection doors and hand-held metal detectors. When the access control system detects non-carried metal items, the alarm system will promptly issue an alarm, and staff members can prevent them from entering the train and reduce the risk of train operations.
High-speed rail surrounding protective equipment and emergency equipment such as fire extinguishers, fire hammers, escape ladders and other emergency equipment. High-speed Rail Security also applies many other security systems/equipment, such as intercom systems, network video surveillance systems, vehicle-mounted DVR monitoring systems, and biometric identification systems. All these security systems are not operated in isolation and are assembled in the entire high-speed rail operation platform. Overall effect.
