Description

Technical Field

[0001] The present invention relates to the technical field of railway passenger car electrics, and particularly to a safety monitoring system for the electric system of a railway passenger car and a railway passenger car vehicle. Background Art

[0002] There are a large number of electrical devices in passenger cars, such as: lighting systems, air conditioning systems, electric tea boilers, electric heating devices, etc. Due to different car body models and ages, the equipment specifications and intelligent levels of the vehicle electrical system vary greatly, so the ability to prevent and control electrical fire safety also varies greatly. As the service life of the train increases, safety hazards such as equipment aging and line aging will inevitably occur, bringing great risks to the safe operation of the train. Once a train catches fire due to electrical reasons, coupled with the enclosed space, high-speed operation, and dense population, the fire spreads quickly, and the risks and hazards are very great.

[0003] All domestic passenger trains in China are equipped with a Train Coach Running Diagnosis System (TCDS) to monitor axle temperature, power supply, doors, undercarriage power supply, fire, air conditioning, anti-skid devices, basic braking systems, etc., and focus on preventing hot axles, fire accidents, power supply accidents, braking systems, and running gear failures of passenger cars. Through communication technologies such as GPRS and WLAN, the monitoring information is transmitted and summarized to the ground, forming a multi-functional, networked, and information-based safety monitoring system.

[0004] However, for the electrical system inside the vehicle, due to the complex system structure topology and scattered electrical loads, there has always been a lack of effective monitoring means. Especially for the DC 600V line in passenger cars, there are problems such as short-circuit faults and arc faults caused by insulation aging and poor contact of vehicle electrical lines, resulting in overheating and burning of electrical lines and equipment. The existing TCDS cannot meet the requirements of adding safety monitoring for the electrical system in terms of system architecture, system capacity, network bandwidth, and ground supporting application upgrade. Moreover, the space constraints of the existing car body structure and the implementation difficulty of installation and transformation of passenger cars all restrict the improvement of the safety capabilities of the passenger car electrical system. Therefore, at present, the safety guarantee of railway passenger car electrical equipment still remains at the stage of relying on manual inspections. This method cannot achieve real-time detection and early warning, and the judgment of the safety status of electrical equipment depends passively on the experience of train inspection personnel.
