产品必须符合标准X、防护等级Y甚至2MOPP,因为电源已被决定用在最近推出的呼吸机上。最重要的是,开发人员还需要考虑MTBF值。想象一下患者连上了呼吸机,而电源突然出现故障…… 这当然要不惜一切代价来避免!因此,开发人员需要知道电源在没有维护的情况下可以安全工作多长时间。这篇关于RECOM的RACM1200-V的文章可以回答其中一些问题。
RECOM认为最安全的选择是唯一的选择,在设计RACM1200-V时就牢记了这一点,电源也必须通过所有必要的认证。
3BHB003230R0101模块,5SHX1445H0001配置手册RACM1200-V树立了对紧凑定义的新标准,涵盖极宽的功率范围,无风扇冷却也能可靠地工作。特殊的基板确保有效散热并提供高达1000W的连续输出功率。RACM1200-V带有两个额外的输出因此不像一些应用需要额外电源,并提供12V可调系统风扇输出和5V/1A待机输出。
由于电源电压和输出电压之间有4kVAC隔离电压,因此RACM1200-V几乎可用在需要电源的所有地方,例如充电器、LED照明系统、激光设备、分析仪器、高频器件、机器人、医疗床椅,以及与患者直接接触的医疗设备。RECOM可为设计人员提供符合规格需求的电源。
虽然RACM1200-V通过IEC 60601-1认证,但不能保证要安装它的设备也符合标准。然而使用认证电源是满足标准的前提之一,除了确实能够降低开发成本还可以加快最终产品的认证过程。
RACM1200-V提供符合2MOPP认证的(MOPP=患者保护措施)绝缘和最小漏电流,这意味着它符合医疗设备的患者安全标准。
信号输出和5V输出与电源电压之间的隔离为1.5kVAC。
RACM1200-V系列具有集成EMC滤波器,可以轻松满足EN 55032:2015 Class B对辐射干扰和线路干扰的要求。新型RECOM电源符合所有工业应用、IT产品和医疗设备相关的国际安全标准。
RACM1200-V的输入电压范围为85 VAC至264 VAC,允许高达1000W的连续输出。采用40mm高的金属外壳,封装面积仅102mm x 229mm,可接触冷却。输出功率可达1200W并维持10秒。若要1200W连续输出,电源必须配备风扇同时确保有2.5m/s的空气流动。这就是为什么RACM1200-V也配备了控制辅助输出以进行温度管理。输出功率:40°C环境温度和230V输入电压的输出功率为1000W;使用风扇或短峰值负载可达1200W。
special hardware multiplier and special instructions, DSP can quickly realize various digital signal processing and meet various high real-time requirements. With the increasing complexity of modern embedded system, operating system has become an indispensable part of embedded system. Free embedded operating systems, such as Linux, have developed rapidly with their continuous improvement. Linux is a free, powerful, reliable, scalable and extensible operating system. Linux implements many theories of modern operating system, and supports complete hardware drivers, network communication protocols and multi processor architecture. The disclosure of its source code is more conducive to the embedded application of the operating system.Based on the above analysis, the author developed a dual core embedded system based on arm and DSP chip. The system makes full use of the respective characteristics of arm and DSP. It can be developed jointly by arm and DSP chips or independently by arm or DSP. Linux is selected as the operating system to give full play to the efficiency of the system.
1. Overall design of the system
Due to the strong control performance of ARM chip, arm is mainly used for control and a small amount of data processing in embedded systems. In this way, on the one hand, the CPU is required to have low power consumption and enough clock frequency to run the operating system to meet the portable requirements; On the other hand, it is also required to have enough interfaces to facilitate the expansion of performance. Based on the above considerations, hy7202 is selected as the CPU in the development platform.
As a part of data operation, DSP can give full play to its unique advantages in digital signal processing.
