Communication method for injection molding machine controller and auxiliary units

Abstract

The invention provides a communication method for injection molding machine controller and auxiliary units and belongs to the technical field of control of injection molding machines. The communication method includes the steps of firstly, setting device address and data address of each auxiliary unit and establishing communication connection between the injection molding machine controller and each auxiliary unit; secondly, establishing real-time data transmission connection between the injection molding machine controller and each auxiliary unit to allow the auxiliary units to send corresponding state information to the injection molding machine controller; and thirdly, by the injection molding machine controller, sending action commands according to the state information sent from the auxiliary units. The real-time transmission data includes the device address, the data address, function code, data byte and check code. The communication method has the advantages of high information transmission accuracy, low cost, multiple variety of transmitted information.

Description

technical field [0001] The invention belongs to the technical field of injection molding machine control, and relates to a communication method between an injection molding machine controller and an auxiliary machine. Background technique [0002] In the plastic industry, an injection molding machine is a plastic injection molding machine. The injection molding machine is equipped with auxiliary equipment to improve the molding efficiency of the product and reduce the rate of defective products, which can improve production efficiency and save energy. Therefore, it is necessary to improve the accuracy of the communication between the injection molding machine controller and the auxiliary machine. The existing communication relationship between the injection molding machine controller and the auxiliary machine is to use digital input and output to realize the transmission of relevant data. At the same time, the existing injection molding machine controller The communication m...

Therefore, it is necessary to improve the accuracy of the communication between the injection molding machine controller and the auxiliary machine. The existing communication relationship between the injection molding machine controller and the auxiliary machine is to use digital input and output to realize the transmission of relevant data. At the same time, the existing injection molding machine controller The communication method with the auxiliary machine has a single transmission method, and the communication method between the injection molding machine controller and the auxiliary machine can only transmit relevant Boolean quantities, and cannot transmit analog quantities such as the temperature information of the mold; at the same time, the existing injection molding machine controller and auxiliary machine The traditional communication method wastes hardware resources. When the user needs to transmit more data, the number of communication modules of the injection molding machine controller must be increased, and more communication lines need to be added, resulting in low hardware utilization and wasteful hardware resources
