Embodiment 1

[0020] figure 1 The flow of the communication fault handling method provided by Embodiment 1 of the present invention Figure 1 , the method is applicable to the field of communication where information is exchanged between the master communication device and the slave communication device. In this embodiment, the train control system of an electric locomotive is taken as an example to specifically describe the communication fault handling method.

[0021] The electric locomotive train control system includes OCU and TCU and other equipment. Among them, the OCU is set on the master locomotive and the slave locomotive, and the TCU is set at the tail of the train. Real-time information interaction is required between the OCU of the master locomotive and the TCU at the tail of the train. , the OCU of the master locomotive and the OCU of the slave locomotive also need real-time information interaction. The OCU of the master locomotive, as the main communication device, can send da...

Embodiment 2

[0050] On the basis of the above-mentioned embodiments, those skilled in the art can understand that the communication connection between the slave communication device and the master communication device to monitor the failure of the communication component can also be performed in the following manner:

[0051] The slave communication device sends a work status message to the third communication component in the master communication device through one of the communication components (for example, the first communication component), and then waits for the master communication device to return a work status decision message, and starts a timer to start counting. If no working status decision message is received within the set time, it is determined that the receiving timeout. The communication parameters of the second communication component are replaced with the communication parameters of the first communication component, so that the second communication component establishe...

Embodiment 3

[0054] Figure 4 It is a schematic structural diagram of a communication fault processing device provided in Embodiment 3 of the present invention. The communication fault processing device may include: a message sending control module 1, a message receiving judging module 2 and a communication parameter exchanging module 3.

[0055] Wherein, the message sending control module 1 is used to control the first communication component belonging to the slave communication device to send a working status message to the third communication component belonging to the master communication device, and the second communication component belonging to the slave communication device to send a working status message to A fourth communication component belonging to the master communication device sends the working status message, the first communication component and the third communication component have the same first communication parameters, and the second communication component and the ...

Abstract

The invention provides a method and device for processing a communication failure. The method includes the steps of controlling a first communication assembly and a second communication assembly which belong to an auxiliary communication device to transmit same working state information to a third communication assembly and a fourth communication assembly which belong to a main communication device respectively, wherein the first communication assembly and the third communication assembly have same first communication parameters, the second communication assembly and the fourth communication assembly have same second communication parameters, and the first communication parameters are different from the second communication parameters; judging whether working state decision-making information returned by the main communication device is received or not within a set time; interchanging the communication parameters of the first communication assembly and the second communication assembly if the working state decision-making information is not received. According to the method and device for processing the communication failure, the problem that a communication mode of an existing electric locomotive train control system is poor in reliability can be solved, and the communication quality of the electric locomotive train control system is improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a communication fault processing method and equipment. Background technique [0002] An electric locomotive dedicated to carrying goods, which has many vehicles and a large load, requires multiple traction locomotives to provide traction power. The electric locomotive usually includes a master locomotive, multiple slave locomotives and several unpowered carriages. The locomotive is equipped with a driver's operating platform, which can be used by the driver to operate the electric locomotive. The master locomotive and the slave locomotive are equipped with an operation communication unit (Operation Communication Unit, OCU for short), and the tail compartment of the vehicle (referred to as the train tail) is equipped with a tail communication unit (Tail Communication Unit, referred to as TCU). The OCU and the TCU are composed of The main communication components of the heavy vehicle t...
