Embodiment 1

[0043] This embodiment applies to Figure 4 The master-slave topology structure, the slave node is connected to the master node through the bus, the typical hardware structure of the master-slave topology can be found in Figure 5 , Figure 5 is the system architecture currently used in the subway, the main node ( Figure 5The above unit (corresponding to the main control unit) will use a powerful processor to be responsible for the main control logic, system external communication, diagnosis and data, etc. From the node ( Figure 5 The lower unit in the middle) uses DSP to be responsible for specific driving and calculation functions, such as inverter unit, four-quadrant unit and adhesion control unit, etc., and the number of each unit can be multiple.

[0044] see image 3 , the end-to-end adaptive synchronization method of this embodiment includes the following steps:

[0045] 1. Startup steps:

[0046] After the master node is powered on, it enters the BOOT state, an...

Embodiment 2

[0057] This embodiment also provides a plug-and-play traction control device based on Embodiment 1, including: see Figure 4 , the master node and more than one slave node connected to the master node through an end-to-end adaptive synchronization bus. The master node is used to implement the master control logic in the device, as well as the external communication, diagnosis and data transmission of the device; operation.

[0058] When implemented, the device also includes a state machine, see Figure 9 , the state machine is used to: after the master node is powered on, mark the master node to enter the BOOT state, and mark the master node to enter the INIT state after the self-test of the master node is normal; after the slave node is powered on, mark the slave node to enter the BOOT state, and After receiving the control command to enter the INIT state from the master node, the slave node is identified to enter the INIT state. After both the master node and the slave nod...

Embodiment 3

[0060] The present invention also provides a computer system, including a memory, a processor, and a computer program stored in the memory and operable on the processor. When the processor executes the computer program, the steps of the method in Embodiment 1 are realized.

[0061] In summary, the present invention provides a set of state machine management, process communication management, and communication management mechanisms based on high-speed real-time communication links, so as to realize the self-adaptive function of application software to hardware devices, and realize the plug-and-play of traction control devices. Ready-to-use and self-adaptive identification of each node and effective fusion of data between multiple nodes, which is conducive to the flexible tailoring and configuration of the module of the device.

Abstract

The invention discloses an end-to-end adaptive synchronization method and a plug-and-play traction control device. The method comprises a starting step of powering on a master node, then entering a BOOT state, and then entering an INIT state after the self-inspection is normal; in the INIT state, polling the states of all slave nodes, and sending a control command for entering the INIT state to the ready slave nodes; after the slave nodes are powered on, enabling the slave nodes to enter the BOOT state, notifying the master node that a local machine is ready after the self-inspection is normal, and entering the INIT state after receiving the control command for entering the INIT state from the master node. According to the invention, the adaptive identification of each slave node can be realized, and the flexible clipping configuration can be realized.

Description

technical field [0001] The invention relates to the technical field of synchronous buses, in particular to an end-to-end self-adaptive synchronization method and a plug-and-play traction control device. Background technique [0002] The traction control device is used to control the traction system. Its functions include: rectification control, inverter control, adhesion control, DCDC, system logic control and external communication. Its functional structure is roughly divided into two types: (1) each control function The signal acquisition, pulse output and calculation functions of the system are all concentrated in one place, following the local acquisition, local calculation and local output, the functional model is as follows figure 1 as shown, figure 1 In , each box represents a node, which is an independent functional unit, and each functional unit corresponds to an independent hardware unit. The logic master is mainly responsible for some logical actions of the whol...
