SEMA®

智能中间件来监视和控制您的设备
凌华科技嵌入式智能管理代理（SEMA）可以弥补一些嵌入式PC系统的安全漏洞。所有支持SEMA功能的凌华产品都配备了一个板卡管理控制器（BMC，Board Management Controller），可以搜集系统管理总线（SMBus）中芯片组的数据。

SEMA - 智能嵌入式管理代理

SEMA® 概述
SEMA功能的凌华产品都配备了一个板卡管理控制器（BMC，Board Management Controller）。这个板卡控制器搜集所有与芯片组和其他源相关的数据。通过系统管理总线驱动程序将这些数据提供给一个软件层并将数据呈现给本地用户。凌华科技提供一个即用型应用程序，通过友好的图形用户界面（GUI）显示数据，非常适用于监控和故障排除。

SEMA Architecture

SEMA®板卡控制功能的选择
SEMA®使操作员能够轻松地将系统控制功能集成到其嵌入式系统中，并实时识别低效率和故障，从而防止故障并最大限度地减少停机时间。并且它可以与工业物联网（IIoT）平台和解决方案以及相应的IIoT网关和代理软件进行简单的集成，从而实现对支持SEMA®的板卡和系统的远程监控和控制。

SEMA Web based interface

Functional Overview
Providing the interface from the hardware to the operating system is one of SEMA®'s most important functions. The BMC first collects all relevant information from the chipset and other sources. Using the I2C driver and the Extended EAPI the application layer fetches the data and presents it to the user. The application can be a local customer specific implementation or the SEMA® Dashboard which can access the Extended EAPI also remotely and which shows the data in user-friendly graphic interfaces, suitable for supervision and troubleshooting.

SEMA® Features
At the heart of SEMA® is the Board Management Controller (BMC) supporting SEMA® functions. The SEMA® Extended EAPI provides access to all functions then. A graphical user Interface allows to monitor and control one or multiple devices / computer modules. So SEMA® comprises:

SEMA® Board Management Controller HW and FW
SEMA® Extended EAPI Library
SEMA® Graphical User Interface (GUI)
SEMA® supports the following functions and information:
CPU Operation Modes
Memory Information
Network Information
ACPI Power Management
HDD S.M.A.R.T
Bios Updates
Heartbeat
Power Consumption
User Area Access
Alerts for Power and Temperature Consumption
I2C Bus Control
Temperatures(CPU and Board)
Board Information (Serial Number, Part Number, Firmware Version...)
1-Wire® Bus support
Logging of Power-Up Failures
Fan Control
GPIO Control

Forensic information is available after system or module failures includes minimum and maximum temperature of the CPU and system, as well as HDD S.M.A.R.T information - all of which can be used to analyze system or module failure.

SEMA® is available for Linux and Windows operating systems and for various HW platforms.
