Embodiment

[0042] First, quantify the application scenario of the input MVB network message data. The method is to quantify the application scenario of the message data into a two-tuple, one group is the number of message-capable devices on the bus, and the other group is each device in each round of event arbitration. Probability of sending message data in .

[0043] Then, distribute the specified number of message data frames to the message data frame sending queue of the device with message capability in the message data application scenario according to the specified probability model. In this embodiment, the probability model is a normal distribution model, and the number of messages is 100,000.

[0044] Finally, different event arbitration algorithms are used on the master device in the message data application scenario to simulate events for arbitration.

[0045] The method of using different event arbitration algorithms to simulate events for arbitration is as follows:

Abstract

The invention discloses a configurable event arbitration method and device of MVB message data. The arbitration method includes the steps of firstly, quantizing and inputting MVB network message data application scenarios; then sending message data frames in a designated number to a device message data frame transmitting queue with message capacity in the message data application scenarios according to a designated probabilistic model; finally, using different event arbitration algorithms to simulate the events on a main device in the message data application scenarios to carry out arbitration. Meanwhile, the invention discloses a configurable event arbitration device of MVB message data. The arbitration device comprises a quantizing application scenario module, a message data frame transmitting module and an event arbitration module.

Description

technical field [0001] The invention relates to the field of event arbitration, in particular to a configurable event arbitration method and device for testing MVB message data. Background technique [0002] The train control systems provided by major international locomotive suppliers to users all adopt the Train Communication Network (TCN) network conforming to the IEC61375 standard, such as SIBAS32 of Siemens and MITRAC of BOMBARDIER. TCN adopts a two-level topology structure, the train bus adopts WTB, and the vehicle bus adopts Multifunction Vehicle Bus (Multifunction Vehicle Bus, hereinafter referred to as MVB). There are three main types of data transmitted on the MVB bus: process data, message data, and monitoring data. Process data are those short and urgent data with definite and bounded transmission time. The control commands and running status information of train operation can be defined as process data. Process data is transmitted periodically; message data is ...
