摘要
针对机载蓄电池组的地面维护需求，基于蓄电池组维护基本原理，结合工控机PCI总线技术，以及数字电源、电子负载等数字设备的MODBuS、SCPI协议，提出一种机栽蓄电池地面维护方法并研制了地面维护系统．解决了传统维护相关技术中的功能单一和缺乏针对性的系统评价等问题。系统实现了机载蓄电池组的充电维护、放电维护和循环充放电维护（活化），保证了运行过程中的安全性，同时通过对电压、电流、容量、时间等过程参量的检测与分析，实现对蓄电池组安全状态的评估。实验结果表明，该系统维护电压范围为0-35V，维护电流范围为0～4A，远端蓄电池组电压最大引用误差小于0．1％．精度等级G达到0．1，实现了机载蓄电池组的地面维护需求。有效保证了机载蓄电池组的应急使用中的稳定可靠运行。
An airborne battery ground maintenance method was proposed and a ground maintenance system was developed in order to meet the airborne battery ground maintenance needs, which is based on the basic principles of battery maintenance, combined with PCI bus technology, and digital power supply, electronic load and other digital devices with MODBUS, SCPI protocol. The system could solve the traditional single fianction and lack of systematic reviews and other issues, and achieve the onboard battery charge maintenance, dischar~,~ng maintenance and charge- discharge cycle maintenance （activated）, to ensure the operation of the safety, while achieving the battery safety assessment through the voltage, current, capacity, and time of process parameters the detection and analysis. Experimental results showed that the system, maintains voltage range of 0-35V, maintaining current range of 0-4A, the maximum reference error less than 0.1% , accuracy class G of 0.1, met the airborne battery ground maintenancneeds, effectively ensuring the airborne battery stable and reliable operation in emergency use.
