The rapid development of modern transportation such as expressway/subway/railway/civil aviation operations constantly requires the transportation industry to achieve automation, informatization, and intelligence. The safe operation of its monitoring, communication, toll and other systems has put forward higher requirements for the power supply and distribution system. Requirements.

1. With the development and growth of transportation intelligence and informatization, various data storage, sharing, application, transmission and other fields rely more on the power system, and a series of power guarantee measures need to be established. On the other hand, most of the stations along the traffic line are far away In cities and towns, the quality of electricity consumption cannot be guaranteed, and the requirements for the safety and reliability of power supply and distribution equipment are very high. UPS power supply has been developed rapidly as a core component of power guarantee.

2. The status quo of power supply problems in the transportation industry

1. Toll stations, billing centers, tunnels, etc. are mostly built in the outskirts of cities, using agricultural power grids, and the input power quality is poor, resulting in serious harmonic interference.

2. The working environment is relatively harsh. Problems such as exposure to the sun, rain, and rapid temperature difference make the load protection level of the weak current system of each site highly demanding on the reliability of the power supply. Once the power is cut off, the normal operation of the toll system will be affected.

3. The modern transportation system integrates a variety of technologies, has a high degree of intelligence and a complex structure. Once the system flashes or fails, it will cause big problems.

4. There are various loads connected to the mains power grid, causing interference and pollution to the power grid, deteriorating the quality of power supply, affecting the normal operation of load equipment, and causing problems such as server data loss.

Three, UPS power supply power protection solutions

1. Analysis of the demand for power security in the transportation industry

(1) Demand analysis and application scenarios in the field of indoor systems and equipment power protection

The objects of indoor power security in the transportation industry include: communications, integrated monitoring, office automation, command and control, automatic fare collection and toll collection systems, fire fighting systems, information transmission and delivery and other transportation systems and equipment power supply and security systems; for conventional For non-sudden power outages, in principle, the backup power generator sets provide power protection for the above systems, but the risks of normal operation cannot be avoided. At this stage, the UPS power supply has been regarded as normal in the design specifications for the power protection system of the transportation indoor system. An important part of the three-dimensional power security system in operation; it can ensure the power supply while improving the quality of the power supply, which can better ensure the high-quality power demand of the system and equipment.

(2) Demand analysis and application scenarios of power protection for outdoor systems and equipment

The objects of indoor power protection in the transportation industry include: signal indicators, road monitoring equipment, lighting systems, signal transmission equipment and facilities, tunnel ventilation and lighting systems, road monitoring systems and equipment, electronic sensing equipment, vehicle control systems, and information transmission As a key component of the intelligent transportation system, whether the outdoor system and equipment can operate normally, in addition to the equipment or system performance and quality, the greatest hazard is the protection of power and power quality; the construction of a three-dimensional The power supply guarantee system is the foundation of traffic safety production.
