Embodiment Construction

[0056] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] Attached with reference figure 1 , with figure 1 A motion control system 100 is shown. In this embodiment, the motion control system 100 is a robot control system. A plurality of motors 107 constitute the moving parts of the joints of the robot to drive the robot to run.

[0058] As an illustration, the motion control system 100 may also be a motor control system, a lead screw control system, a solenoid valve control system, and the like.

[0059] This embodiment takes the robot control system as an example for illustration. Each joint of the robot needs to be driven by a motor 107. The motor 107 is connected with a reducer, and the calculator drives the joints to rotate through the rotation of the output shaft. A robot ge...

Abstract

An address allocation method of a CAN communication network is used for the CAN communication network including main nodes and slave nodes and comprises the steps that S1, device parameters corresponding to the slave nodes and Hash values corresponding to the device parameters are stored on the slave nodes; S2, the main nodes send first device parameter query commands to all the slave nodes through broadcasting; S3, the slave nodes send the corresponding Hash values to the main nodes according to the first device parameter query commands; S4, the main nodes allocate CAN addresses to the received Hash values and send the CAN addresses to the corresponding slave nodes. The CAN addresses can be conveniently and quickly allocated for multiple slave nodes by adopting the address allocation method.

Description

technical field [0001] The present invention relates to the address allocation technology of CAN communication network, in particular to an address allocation method of CAN communication network, a motion control system including CAN communication network, a gateway and a computer-readable medium storing computer programs . Background technique [0002] In the field of motion control, in order to achieve synchronous control of multiple motion control components, the motion control system can use the CAN bus to form a CAN communication network. The CAN communication network can integrate up to hundreds of motion control components into the same motion control system. . [0003] In a motion control system, it can include a CAN communication network master node and several slave nodes, and the communication between the master node and the slave nodes can be established through the CAN data line. The master node is the master controller in the CAN communication network. Each s...
