系统工作原理

Working principle of the system

FMCS 系列变频同步控制系统是一种闭环控制系统，是基于变频控制技术 (VFDM) 与传感器技术来控制千斤顶升降及准确定位。控制过程无需考虑重物的中心分布，适用于对大型、重载结构进行整体顶升作业。

FMCS series variable frequency synchronization control system is a closed-loop control system, which is based on the variable frequency control technology (VFDM) and sensor technology to control the lifting and accurate positioning of the jack.The control process does not need to consider the center distribution of heavy objects, which is suitable for the overall lifting operation of large and heavy load structures.

VFDM 技术实现了真正意义上的连续流量调节，通过连续改变电机的转速来调节流量的大小。因此变频控制技术在平稳性和可靠性方面要高于同类型的其他系统。

VFDM technology realizes continuous flow regulation in real sense, which can adjust the flow rate by continuously changing the speed of the motor.Therefore, frequency conversion control technology is higher in stability and reliability than other systems of the same type.

每个控制点兼有压力和位移双重控制系统 ，可实现同步升降、同步顶推、重载称重、等比例升降、姿态调整等多种功能。基于PLC 控制的同步顶升系统减少了重量分布不均和不同顶升点间负载转移造成的折弯，扭曲和倾斜的危险。

Each control point has dual pressure and displacement control system, which can realize synchronous lifting, synchronous pushing, heavy load weighing, etc.The synchronous jacking system based on PLC reduces the risk of bending, twisting and slanting caused by uneven weight distribution and load transfer between different jacking points.

特点：

采用双泵系统，实现了高速置零，平稳顶升的功能。

The double pump system is adopted to achieve the function of high speed zero setting and smooth lifting.

完全计算机控制，顶升过程无需人工干涉，系统自动检测顶升状态并能根据顶升情况给出。

Complete computer control, lifting process without manual interference, the system automatically detects the lifting status and can be given according to the lifting situation;

同步控制精度可以达到 0.1mm，同步顶升和同步下降都完全可控。

The accuracy of synchronous control can reach 0.1mm, and synchronous jacking and synchronous descent are completely controllable.

每个控制点油路相对独立，系统压力可以单独调节互不干涉。

Each control point is relatively independent and the system pressure can be adjusted independently of each other.
