It should be noted that the 485 communication interface specifically refers to a remote weighing data acquisition method, and the RS-485 serial bus standard is widely adopted when the communication distance is required to be several tens of meters to thousands of meters. RS-485 adopts balanced transmission and differential reception, so that the capability of suppressing common mode interference is realized.

The CAN network between the driver 12 and the controller 11, the communication protocol specifically adopts the CANopen protocol, the controller 11 serves as a CANopen master station, and the driver 12 serves as a CANopen slave station. And the 485 network between the driver 12 and the heating mechanism 13, the communication protocol specifically adopts a Modbus (a serial communication protocol), the driver 12 is a Modbus master station, and the heating mechanism 13 is a Modbus slave station.
Through the relay of the driver 12, the heating mechanism 13 can realize the networking of the control system of the injection molding machine 10 through lower cost. And the whole control system of injection molding machine 10 only need connect 485 communication cables and CAN communication cable CAN to the connection of physical pencil has significantly reduced, and then CAN reduce installation, distribution and debugging man-hour in a large number, improves production efficiency, possesses nimble extended characteristic simultaneously, adapts to the constantly changing of control system demand.
The specific control implementation scheme is that internal parameters, control commands and state information (software version, temperature of the heating mechanism 13, voltage of the heating mechanism 13, current of the heating mechanism 13, fault information of the heating mechanism 13, output state of the heating mechanism 13, self-test state of the heating mechanism 13, and the like) required to be set by the heating mechanism 13 are added in a CANopen object dictionary of the driver 12, the driver 12 serves as a CANopen slave station to respond to a CAN message command of the controller 11, and the driver 12 serves as a Modbus master station to perform parameter setting on the heating mechanism 13 through the Modbus message setting when receiving the CAN message command, and CAN also periodically read the state information of the heating mechanism 13, and the controller 11 CAN perform information interaction with the heating mechanism 13 through a CANopen address (index, sub-index) through the relay of the driver 12.
It can be understood that the complete machine testing tool of the injection molding machine 10 can also access the address of the heating mechanism 13 in the driver 12 through the Modbus protocol, and indirectly acquire the information of the heating mechanism 13, so as to facilitate the complete machine debugging. And the control system of the injection molding machine 10 can be realized only by correspondingly upgrading the software of the driver 12 and the heating mechanism 13 and increasing the communication address when a new interaction requirement is subsequently required, and the physical connection line is not required to be changed.
