本发明测控***引入***冗余背板和插座墙设计理念,设计单机插拔式安装结构的背板箱,互为备份的单机分别与背板箱的输出接口连接,单机的各种输入、输出接口信号在背板箱中完成同种信号的合并,实现设备级的冗余,从背板箱的插座墙统一对***的输入、输出接口,简化设备间连接形式,减小单机结构体积。从***级解决方案中单机互为热备份,在不断电情况下更换故障单机的热插拔设计难点。
背板箱中主要进行冗余电信号的合并设计,通过接口板、汇流条等将单机的各种输入、输出接口信号在背板箱中完成同性质信号的合并。由背板箱的插座墙统一配电测控子***对外的输入、输出接口。
a)背板箱结构设计
单机机箱由定位导向控制沿设备托盘推入背板箱,并与背板箱接口推入插合,更换时,可轻力分离拔出。
背板箱结构设计时,与机柜的承力支架、机柜设备的托盘、单机机箱、单机机箱推入的定位导向进行整体设计,保证单机机箱与背板箱间接口对接满足公差要求。
背板箱的输入接口为:带定为导向销、推入插合、轻插拔力分离的J95系列框架面板组合式矩形电连接器。
b)对各单机的设计要求
各单机对有***冗余要求的支路要设计有单机保护电路,防止故障单机将故障点引入和电流倒灌。
供配电单机将监测的工作电压、电流、供电状态等各种参数,通过1553B总线数据传输通道传输到测控设备,测控设备进行汇总和转换处理,再通过测控网络传输到测控计算机进行监测。单机出现故障时,可通过监测信息及时发现。
具体的实施方式主要包括供配电测控子***设计、热插拔冗余设计。具体步骤为:
1、热插拔冗余设计
两台相同的配电控制组合和一台配电控制组合背板箱组成一套产品,两台配电控制组合互为热备份。
配电控制组合背板箱内部没有阻容、半导体等电子元器件,它的主要功能是连接两台配电控制组合,背板箱内部两侧分别配有导向装置引导配电控制组合顺利***背板箱,通过撞接式的接插件连接两台配电控制组合,实现并联备份,单机故障情况下实现配电控制组合快速更换,提高供电可靠性和维修性。接插件采用自带定位销框架的J95系列面板组合式矩形电连接器,可以实现盲插和快速分离。
配电控制组合采用双机并联冗余的工作方式。由于对外输出均是直流信号,故采用了二极管互顶的方式实现并联。
2、故障隔离设计
1553B控制单元用于接收***的总线指令,并将其转化为继电器线包控制信号,继而实现各供电支路的供配电功能。配电控制组合控制单元组成框图如图1所示。
为了在节点发生故障时不影响总线上其它节点正常工作,配电控制组合采用变压器耦合方式连接到1553B总线上,故障隔离部分原理框图如图2所示。
3、实时监测设计
配电控制组合具有自我检测功能,采集各供电支路的供电信息以及本机参数,为了防止测量对各路供电的影响,各路电压及电流测量均采用隔离测量方式,将被测各路模拟量隔离采样送总线控制单元处理;配电控制组合作为RT,将总线控制单元处理的数字信号经总线上传至***BC,BC将所有采集到的信息进行转换,经以太网周期向后端发送并在后端监测界面上显示,实现各种检测功能。
当两台配电控制组合上传的通断数据不同,根据***发送的指令,即可判断是否有故障以及故障位置。
4、工作状态采集电路设计
配电控制组合要求上传当前工作状态,原理如图3。
图3中R3、R5阻值10kΩ,R4阻值为1kΩ,R1阻值为68Ω,R2阻值为680Ω,V3为3.3V稳压管,V2型号为BT4401,V4型号为1N4148,V1型号为2CZ103H,U1型号为V0618A-3。
图3中R2的左端接收软件电路传来的1553B总线信号,当1553B总线信号为高电平(为3.3V),光耦U1导通,R3的左边的电压约为27V,从而电流通过V3进入V2基极,此时V2导通,继电器K1动作闭合。同理,当R2左端为低电平,K1复位。
可选的,V4的阳极接收前端***的手动控制信号,当其为高电平,R5的左边的电压约为27V,因此与U1导通类似,V2导通,K1动作,当V4阳极没有接收到控制信号,K1复位。
下面复算三极管V2的发射极-集电极电流最大电流,看是否满足K1导通要求。当V2导通,其基极电压(也就是R4两端电压)被钳位至0.7V,因此流过V3的电流为(27V-3.3V)/10kΩ=2.37mA。输入到V2基极电流为2.37mA-0.7V/1kΩ=1.67mA。三极管V2的放大倍数为100至300,故V2的发射极-集电极电流最大可达167mA至501mA。
配电控制组合的主控芯片采用TI公司的TMS320F2812系列数字信号处理器。1553B协议芯片772所的B61580S3芯片,该协议芯片包含微处理器和1553B总线之间完备的接口,具有BC、RT、BM三种工作模式,提供了一个4K字的内部共享静态RAM和与处理器总线之间的缓冲接口,软件接口包括17个内部共享操作寄存器、8个测试寄存器以及64K字的共享存储器地址空间。
本发明虽然已以较佳实施例公开如上,但其并不是用来限定本发明,任何本领域技术人员在不脱离本发明的精神和范围内,都可以利用上述揭示的方法和技术内容对本发明技术方案做出可能的变动和修改,因此,凡是未脱离本发明技术方案的内容,依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化及修饰,均属于本发明技术方案的保护范围。
本发明说明书中未作详细描述的内容属本领域技术人员的公知技术。
