Description
技术领域
本发明涉及一种用于提供电流的设备,其具有多个电流源组件。
背景技术
电流源通常作为独立设备运行。它们一般具有简单的报警接点。由此可以示出当前电流源的状态是没有干扰的还是有干扰的。
典型地,电流源将输入侧的例如为230V或400V交变电压的高电压电平转换为例如为24V直流电压的低电压电平。由此可以用合适的电压来运行如传感器、电控制器、阀和泵的耗电器,而不必为每个耗电器配备单独的电流源。这样的电流源例如广泛地应用于制造技术和自动化技术中。
在DE 10355613.3中描述了一种用于电流源的诊断单元和一种具有诊断单元的电流源。诊断单元监控电流源输出侧的至少一个被监控参数与比较值之间是否存在不允许的偏差。在与比较值之间有不允许的偏差的情况下,诊断单元在一个时间窗内采集不允许偏差的时间范围内电流源输入侧的测量值。然后诊断单元将所属的测量值存储在存储器中。由此可以没有疑问地记载由电网侧干扰引起的被监控参数的偏差,如低于输出电压。以这种方式电流源的运营者可以指出不是电流源,而是在上层的电网未满足运行该电流源的特殊要求。对于输入和输出侧电网故障以及电流源侧的设备故障可以很小的开销毫无问题并及时地进行采集、查询和分析。在一种实施方式中,诊断单元具有用于读取存储器的通信接口。通过该接口可以从存储器中读取测量值并例如在连接的个人计算机上用适当的软件进行分析。通过诊断单元的通信接口还可以进行遥控。在此可以向连接的个人计算机传输在线测量值并对其进行分析。此外还可以将用于被监控参数的新固件或新值加载到诊断单元的控制单元中。
发明内容
本发明要解决的技术问题是,改进公知电流源的工作方式。
本发明的技术问题通过具有权利要求1特征的电流源来解决。本发明的优选实施方式和扩展由从属权利要求给出。
本发明的优点尤其在于,通过电流源所有组件的可通信性可以对电流源的所有内部参数进行分析、记录、调节和控制。由此可以实现电流源管理,其中考虑电流源的所有内部参数。
如果电流源组件通过集线器与公共分析和控制单元连接,则可以有利的方式以与电流源组件和集线器之间的连接不同的方式实现集线器与分析和控制单元之间的通信连接。例如电流源组件和集线器之间的连接可以是采用电缆实现的总线,而集线器与分析和控制单元则可以通过无线通信信道连接,如无线传输段。
优选分析和控制单元具有存储器,用于持久存储或记录涉及电流源组件的状态消息。所存储的值用于过后对电流源设备进行准确的分析,如在运行故障情况下的分析。
根据本发明的另一实施方式,各电流源组件分别具有存储器。这些可以环形存储器形式实现的存储器用于在特定的时间窗期间存储涉及各电流源组件的参数,并在分析和控制单元调用时提供这些参数。
附图说明
以下借助附图举例说明本发明的其他具有优点的特性。图中示出:
图1示出用于提供电流的设备的第一实施方式的框图;
图2示出用于提供电流的设备的第二实施方式的框图。
具体实施方式
图1示出用于提供电流的设备的第一实施方式的框图。所示设备具有包含多个电流源组件2、3、4、5、6的电流源1。这些电流源组件是基本装置2、缓冲器模块3、无间断电流源模块4、冗余模块5和诊断模块6。基本装置2连接到交流电网,并在输出端提供经调节的24V直流供电电压。缓冲器模块3用于桥接短时电网中断。无间断电流源模块4用于桥接长时间电网中断。冗余模块5例如在基本装置2发生故障时或者也可以在电流源高负载的情况下被启动。诊断模块6用于在输出侧监控电流源1的被监控参数是否与比较值之间存在不允许的偏差。
基本装置2具有存储器2a。缓冲器模块3具有存储器3a。存储器4a属于无间断电流源模块4。冗余模块5具有存储器5a。诊断模块6包括存储器6a。存储器2a、3a、4a、5a和6a分别实现为环形存储器并在预定时间窗期间存储描述各组件状态的数据。
然后在预定时间间隔过后或在通过外部分析和控制单元7调用时,这些数据被循环地输出给各组件的接口S并提供给总线10。
该总线可以是以太网、Profibus、IEC总线或CAN总线。替代地,接口S还可以是至因特网的接口、GSM接口、UMTS接口、USB接口、无线接口或红外线接口。
外部分析和控制单元7优选是个人计算机。其具有键盘7a、处理器7b、存储器7c和显示器7d。分析和控制单元7接收并分析通过总线10传输的电流源1的各电流源组件2、3、4、5、6的数据。因此分析和控制单元7总是了解电流源1的所有内部参数,并因此能够实施电流源管理。在此,分析和控制单元7发出命令信号或控制信号或控制程序,它们通过总线10传输给电流源1的各组件2、3、4、5或6并影响各组件的工作方式。此外,处理器7b负责将相应于电流源1内部参数的数据持久存储或记录在存储器7c的一个存储区域内,以便在需要时用于过后的分析。此外处理器7b还负责在作为电流源监视器的显示器7d上以字母数字的方式和/或以图形的方式显示为各装置的维护人员提供关于各电流源组件的状态的信息的图或表格。
由各电流源组件通过总线10向分析和控制单元7传输的状态消息例如是:
基本装置2向分析和控制单元7报告测得的输出电流和测得的输出电压、关于该基本装置的状态是受干扰的还是未受干扰的信息、关于是否存在短路情况的信息、关于是否存在过载情况的信息、关于该基本装置内部环境参数(如那里的主导温度和湿度)的信息,以及关于其它阈值和实际值的信息。
缓冲器模块3向分析和控制单元7报告当前充电状况、关于该缓冲器模块的状态是受干扰的还是未受干扰的信息、关于该缓冲器模块当前是活跃的、不活跃的或处于待机状态的信息,以及关于其它阈值和实际值的信息。
无间断电流源模块4向分析和控制单元7报告缓冲是受干扰的还是未受干扰的、该模块处于使用中还是待机运行,蓄电池的充电状况如何、蓄电池是否可更换、剩余的缓冲时间、涉及电池保护的信号(过度放电保护、断线、变换极性)以及缓冲时间的持续长度。
冗余模块5向分析和控制单元7报告电流源是受干扰的还是未受干扰的、是否存在短路情况、是否存在过载情况以及是否存在会使冗余运行不可能的过高的总电流。
诊断模块6也向分析和控制单元7提供涉及诊断模块6的当前运行状态和作用能力的消息信号。
分析和控制单元7通过总线6向各组件例如回送下列控制信号:
-调节基本装置2的输出电压的控制信号,
-调节基本装置2的电流边界值的控制信号,
-调节基本装置2的过载特性的控制信号,
-引起特征曲线转换的控制信号,
-涉及无间断电流源4的蓄电池充电的控制信号,
-涉及无间断电流源4在缓冲运行和充电运行之间转换的控制信号,
-涉及缓冲运行下的电流边界值的控制信号,
-涉及蓄电池测试参数的控制信号,等等。
图2示出用于提供电流的设备的第二实施方式的框图。图2所示设备与图1所示设备的不同之处仅在于,在电流源1的电流源组件2、3、4、5、6与分析和控制单元7之间设置了集线器8。该集线器8通过总线10与所述电流源组件2、3、4、5、6连接。集线器8还通过通信信道9与外部分析和控制单元7连接。
该第二实施方式的优点尤其在于电流源组件和集线器8之间的连接可与集线器8和分析和控制单元7之间的连接9不同地实现。例如电流源组件2、3、4、5、6和集线器8之间的连接可以是有线的总线导线,而集线器8与分析和控制单元7之间的通信信道9例如可以是无线传输段或因特网。这使得分析和控制单元7可以远离集线器8,并由此还可以远离电流源1。
因此按照本发明的用于提供电流的设备具有多个电流源组件,这些电流源组件分别具有一个通信接口。这些电流源组件通过这些通信接口直接或通过集线器与外部分析和控制单元连接。分析和控制单元在在线运行的意义下监控电流源的所有参数,并在识别出故障情况时例如改变电流源的运行方式。分析和控制单元例如控制冗余运行、紧急运行或负载分配。在在线运行中报告的电流源各组件的参数被记录在分析和控制单元的存储器中并在需要时用于过后对电流源的详细分析。根据本发明的电流源管理提高了整个电流源***的可用性和可靠性,并由此也提高了使用该电流源***的自动化***或制造***的可用性和可靠性。
与借助附图描述的实施方式不同地,还可以用编程设备、存储可编程控制器或遥控单元取代个人计算机来作为分析和控制单元7。
按照本发明的设备可以具有优点的方式使分析和控制单元7产生控制信号,根据该控制信号来转换电流源1的工作方式或改变对其的编程,例如从电流源运行方式转换到充电设备运行方式。这种转换可以纯由软件实现或采用设置在各电流源组件中的开关实现,这些开关的开关操作由分析和控制单元7控制。这样的开关在图1和2中用虚线示出,并标以附图标记2b。
