摘要:

［目的］為滿足城市軌道交通信號系統(tǒng)電源的可靠性、維修性和安全性要求，提高信號系統(tǒng)電源穩(wěn)定性，需要結(jié)合鋰電池管理，研究信號系統(tǒng)電源健康管理方案。［方法］介紹了信號系統(tǒng)電源健康管理方案的整體架構(gòu)。分別介紹了信號系統(tǒng)電源健康管理系統(tǒng)與鋰電池管理系統(tǒng)的架構(gòu)、功能及功能實現(xiàn)，闡述了二者的聯(lián)動內(nèi)容。［結(jié)果及結(jié)論］信號系統(tǒng)電源健康管理系統(tǒng)能實時監(jiān)測信號電源狀態(tài)，評估各部分健康度，并預(yù)測告警。信號設(shè)備功率提升使得對高效備用儲能的需求增加。鋰電池管理系統(tǒng)監(jiān)控電池的充放電電壓及電流，以及溫度，采取保護措施，并利用數(shù)學(xué)方法估算電池的剩余電量和剩余壽命。二者聯(lián)動能有效提高信號系統(tǒng)電源的整體穩(wěn)定性和安全性。

［Objective］ To meet the reliability, maintainability, and safety requirements of the power supply for urban rail transit signaling system, and to enhance the stability of the signaling system power supply, it is necessary to incorporate lithium battery management in studying SPHM (signaling system power supply health management) scheme. ［Method］ With an introduction to the overall architecture of SPHM scheme, the architecture, functions, and functionality implementation of SPHM and lithium battery management systems are described respectively, and the interaction between them is elaborated. ［Result & Conclusion］ The SPHM system can monitor the real-time signaling power supply status, evaluate the health of various components, and send predictive alarms. The increase of signaling system power will lead to an increased demand for efficient backup energy storage. The lithium battery management system monitors the charging and discharging of voltage, current and temperature of the battery, implements protective measures, and estimates the SOC (state of charge) and lifespan using mathematical methods. The interaction between the two systems can effectively enhance the overall stability and safety of the signaling system power supply.
