How does the UPS guarantee stable operation in the signal system?
Uninterruptible Power Supply (UPS) is an integral part of modern traffic signal systems. With the acceleration of urbanization and the increase of traffic flow, the traffic signal system is particularly important in ensuring the safety and smooth flow of road traffic. UPS can provide stable power guarantee to ensure the reliable operation of traffic signal equipment in various situations.

High reliability and high security requirements
As the heart of the signal power system, the UPS must meet the requirements of high reliability and high security. Therefore, the UPS products with online double transformation design, advanced full digital control technology and complete network management functions should be selected.
Dual UPS operation scheme
In order to improve the reliability of the signal system power supply equipment, the signal single UPS power supply equipment can be optimized according to the actual demand, and the signal power dual UPS operation scheme can be formed. In this way, when the two power supplies of the external power grid fail, the UPS power supply can carry the normal power supply of the signal system devices within the specified time.
Milliseconds switching capability
The UPS power supply should be able to switch in milliseconds during the switching process of two power supplies or the instantaneous power failure of the signal system, and output stable and high-precision power waveform to ensure that the signal device does not power off or break down.
Monitoring function
UPS should have its own monitoring function, the system status and alarm information through digital communication to the power monitoring system, in order to monitor the working status of UPS in real time.
Distributed autonomous parallel technology
With reliable distributed autonomous parallel technology, multi-machine parallel and later expansion can be achieved to improve the flexibility and scalability of the system.
Reasonable system structure layout
The system structure layout should be reasonable and easy to master, operate, and maintain to reduce maintenance difficulties and improve maintenance efficiency.
Improved power supply reliability
When the active power supply is faulty or interrupted, the UPS can quickly switch to the standby power supply to ensure continuous power supply for key devices and prevent device shutdown and data loss caused by power faults.
Ensure equipment stability
The UPS has the functions of voltage and frequency stabilization, which can effectively eliminate the interference of voltage fluctuation and frequency drift in the power supply, ensure the stable operation of key equipment, and extend the service life of the equipment.
Response to emergencies
The UPS power supply can provide backup power for the emergency braking system to ensure that the train can stop quickly in an emergency to ensure the safety of passengers and vehicles.
Optimized configuration scheme
According to the fault situation in actual operation, the corresponding configuration optimization scheme is proposed to ensure the sustainable power supply for the signal system and provide guarantee for the stable operation of various devices.
CONCLUSION
Uninterruptible power supplies (UPS) play a vital role in traffic signal systems, ensuring the stable operation of signals and other critical equipment. UPS supports traffic safety and management by providing uninterrupted power supply, ensuring system reliability, and improving the ability to respond to a variety of unexpected situations.
