| 摘要: |
| 传统的直流屏均采用对蓄电池组进行整体充电的方式，通过主充、浮充和均充三种方式对蓄电池组进行充电。长期运行在这种方式下，容易造成某些蓄电池的过早损坏。提出了一种新型直流屏的设计方案．在该方案中，为每个蓄电池设计配置一个单元控制模块，负责该蓄电池的充放电过程的监控。另外设置一个总控制模块负责整个直流的控制及显示工作。各个控制模块之间通过RS-485总线与Modbus协议组成一个总线型控制系统。新方案有效地保证了蓄电池的长寿命运行。 |

| Abstract: |
| The batteries of traditional DC cabinet are charged as a whole through three ways:main charge mode,float charge mode and even charge mode. Charging in this condition for long time,some batteries may damage earlier. A new design of DC cabinet is supposed,in which an exclusive control module is equipped for each battery to supervise and control its charge and discharge processes and a management module is designed to manage all these control modules and display the working conditions. All modules are connected together via RS-485 bus and Modbus protocol,which forms a field-bus type control system. The modified scheme helps to ensure the long time operation of storage battery. |
