Nowadays, modern firing installations are subjected to severe demands. On one hand, the combustion of the fuels used must be optimized and any losses minimized and on the other, it is necessary to meet stringent environmental criteria. Furthermore, very high safety constraints are placed on such systems. As a result, the ratio between the volume of air and the amount of fuel used must be accurately adjusted -across the burner''''s entire output range.
当今，对于现代燃烧设备的要求越来越严格。一方面，燃料的燃烧必须优化且降耗；另一方面，必须符合严格的环保标准。此外，对于此类系统的安全性能要求越来越高。因此，必须通过燃烧器助燃空气与燃料精确的自动比例调节来实现上述要求，且比例调节为全量程的输出范围。
The mechanical systems employed up to now can no longer achieve this. Mechanical linkage via levers and rods suffer from too much play to allow the necessary precision. What would be more obvious than to replace mechanical links by modern, fail safe operating electronics?
机械系统至今无法实现上述要求。机械连杆及辅件控制精度较差。什么装置可以代替机械连杆，且可以屏蔽现代电气系统的安全隐患呢？
Here LAMTEC has the right solution: The VMS Compound Management System.
兰姆太克公司(LAMTEC)持有现成的解决方案：VMS复合燃烧管理系统。
The VMS Compound Management System is the logical development of the VR 2/VR 4 ratio regulators, success- fully introduced into the marketplace many years ago. With VMS you can accurately control up to 5 positioning elements as a combined system. And for each element you have free choice whether you wish to control it via three-state-step positioning outputs (DPS) or via 0/4 to 20 mA.
VMS复合燃烧管理系统是在VR2/VR4比例调节器的基础上发展而来的，已成功进入市场多年。通过VMS您可以精确地控制多达5个位置通道，且每个通道可自由选择输出类型，即可为三点开关式位置输出（DPS）或0/4~20mA输出。
However, VMS can do a lot more than just replacing the burner''''s mechanical mixing system. By using up to eight! curve sets, you can adjust complex special firing installations for the most varied operating modes.
然而VMS不仅仅可以替代燃烧器机械混合系统，她还能够实现更多的功能。通过多达八条曲线，可以使您能够调节复杂的专用的燃烧装置，从而实现各种各样的运行模式。
For example: 例如：
l Firing two fuel boilers with joint blower, also laid out for one-burner operation with oil and gas. 含有引风连接器的双燃料锅炉，也适用于燃油和燃气的双燃料燃烧器的控制。
l Simultaneous combustion of two or more fuels with stepped mixture ratios. 同时燃烧两种或更多种燃料的步进式混合比例控制。
l Single/group operation of several burners in one combustion chamber.同一个燃烧室内多个燃烧器的单个或多组燃烧器控制。
And all this with precision and reproducibility which no mechanical system can achieve.
所有上述精准及可重复性的功能不是一个机械系统能够完成的。
You can shift the position of the servo motors via two correction inputs, ie. to build up a control loop. This compensates all interference which influences the firing process.
您可以通过修正两个输入参数改变伺服电机的位置来建立新的循环控制。本功能将对影响燃烧过程的所有因素进行补偿。
Operation is simple. Fuel and air are manually started up and the parameters saved by the operator, point for point. During automatic operation, the stored points are implemented by the VMS with an accuracy of 0.1 degrees of angle -error-free!
操作简便。燃料和助燃风用手动启动，操作点的参数值逐点保存。在自动运行期间，VMS将按照存储点自动运行，精确度为0.1度（角度误差），出错率为零。
The display of operational and error messages is in plain text, including in the relevant national language. There is an integrated operating hour counter, which also totals the burner''''s operating hours for each fuel. All start-ups are also counted separately for each operating mode.
操作及错误信息的显示为文本模式，包含多国语言。具有运行时间计数器，亦可包含燃烧器的每一种燃料运行的累计时间。所有的启动次数及各操作模式的运行时间均被记录。
If required, the VMS also takes over the burner''''s output regulation.
如果需要，VMS也可接管燃烧器输出调节。
The VMS analog inputs can be configured to the most diverse physical input quantities via plug-in cards. The parameters of many software functions, such as e.g. a final ventilation period, can be set by the operating personnel on site.
VMS可通过外接插入式板卡扩展更多的模拟量输入点。其还提供很多软件功能的参数设定，如：后吹扫的时间等可由操作人员就地设定。
A software module O2-/CO control is integrated into the VMS. In combination with the O2/CO-measurement devices LT1/LT2 via the LAMTEC SYSTEM BUS every firing installation can be maintained constantly at the ideal operating point, independently of environmental conditions such as temperature and air pressure.
VMS集成了氧气/一氧化碳控制的软件模块。通过兰姆太克(LAMTEC)系统总线接入氧气/一氧化碳分析设备LT1/LT2，无论环境温度和空气压力如何变化，燃烧器均可持续稳定地运行于理想的工作点。
The VMS can be very effectively combined with existing control systems. It "speaks" almost all the languages of conventional field buses.
VMS通过各种常规通讯协议可以有效地溶入现有的控制系统。
The VMS is TÜV-tested and also meets the TRD 604 requirements for continuous operation.
VMS已通过TÜV认证，而且满足TRD 604对于连续运行设备的要求。
An additional PC interface significantly facilitates the operator''''s work with the VMS. The unit can be remote-controlled from a laptop, and the selected configuration plus the curve data can be saved. If it should ever be necessary, a replacement unit can thus be readied for operation within seconds: the back-up data are simply read in.
扩展的PC接口使得VMS的操作工作更加容易、简便。通过PC可进行远程控制监视、远程设定曲线、远程修改参数等所有功能。即使需要更换一台VMS，也只要很短时间便可投入运行，因为通过PC可直接把原系统的数据转移到新的设备中。
By using an industrial modem, the VMS can also be interrogated from your office. In the event of a fault you can find out the cause of the fault with using the remote software or even shut off the burner.
VMS也可直接通过调制解调器进行远程监测，当发生故障时，您可以利用远程监控软件诊断故障的原因，甚至关断燃烧机。
