So the liquid filling machine market is development potential. At present, various filling machine production factory production of filler in bottle type filling capacity, efficiency, suitable scope and degree of automation, etc, each have advantages and disadvantages. To a great extent它已經(jīng)發(fā)展成液體食品行業(yè)，并對(duì)世界和大市場(chǎng)占有率有很大的影響[ 1 ]。 the minimum filling capacity is 240 ml, suitable for glass bottles, PET, cans, etc. the control form includes automatic control and manual control [2].The machine drive system uses frequency conversion motor, Can according to the production of canned reasonable to adjust motor rotation speed. Hydraulic cylinder is equipped with liquid level automatic controller, if in the process, there have unfilled bottle phenomenon, the machine can immediately automatically stop filling.This design is based on the research of filling machine of Programmable Logic Controller (PLC) control system, integrated Programmable Logic Controller (PLC), frequency converter control and the application of puter technology, more paragraphs of the frequency converter speed control by PLC, make the speed of the motor as feedback signal detected changes, so as to achieve control of the filling machine filling speed, make the filling machine programming convenient, and improve the efficiency of industrial production.At the same time make filling machine maintenance convenient, saving the time of adjustment program, increase the flexible of filling machine, stable and reliable running at the same time. Filling machine for filling material is from belongs to the category of machinery, packaging machinery, is an important part of the filling production line.China packaging machinery has developed into the world of liquid food industry has a significant impact and maximum market share of industry. Therefore, the development of liquid filling machine has potential market. Filling machineproduction of various filling machine manufacturers present in filling capacity, efficiency, appropriate bottle type range and degree of automation has its advantages and disadvantages, greatly restricts the product quality and production efficiency. Filling machine is a kind of packaging machinery, widely used in food, chemical, pharmaceutical and other industries.Using filling machine can not only improve labour productivity, reduce the loss of product to ensure the quality of packaging, and can reduce the production environment is loaded with crosscontamination of materials. Thus, modern packaging industry is generally mechanized filling machine.II. SYSTEM COMPOSITIONA. The Structure of the Control SystemUsing PLC as the control system of the main control device, sensor as the detecting device, frequency converter as the motor speed control device and a connected to a puter through a munication protocol or connected with HT7A00T manmachine humanputer interface. The control system structureTo monitor the production line and record data processing products, the filler control system consists of a main Programmable Logic Controller (PLC) and 3 auxiliary expand Programmable Logic Controller (PLC),main PLC is LM3106A,filling machine ,checkout switch, panel buttons, inverter motor control and electromagnetic valve. By Programmable Logic Controller (PLC) according to the detection of sensor signal by editing program to plete a series of actions such as filling .B. The Control System AlgorithmMotor speed signal of this system is turned into electrical signal by the transmitter and loaded into the controller. On the basis of the signal, Programmable Logic Controller (PLC) automatic shows a data. After paring the two speeds, based on the deviation of the control signal it have been taken to frequency conversion governor, In order to adjust speed of the motor, it have to eliminate the speed deviation with the actual data.By modifying the deviation caused by the mechanical disturbance, production line of the motor speed constant, at the same time to ensure the production line efficiency. This system is a closedloop control system based on motor speed.This system uses the Proporti
