In one MVB network element, two central control devices 20 may be provided, one of which is the master central control device and the other of which is the slave central control device, for redundancy control.
The task control signal is usually sent by the main central control device, the same redundant task control signal is sent from the central control device at the same time, but the control of the main central control device can be influenced by the central control device, namely, signals such as blocking or turning off can be generated under the condition that the main feedback and the auxiliary feedback are inconsistent; the two central control devices respectively work independently, and when the main central control device has a problem or is turned off, the central control device can independently complete the control task. On one hand, the implementation mode of the double central control equipment can restore the actual operation condition of the existing central control equipment of the train network to the maximum extent; on the other hand, because the work of each unit is generally controlled by using double central control devices in the existing actual train, when the main central control device has a fault, the master central control device is switched to be continuously controlled by the slave central control device, so that the train low-voltage electrical simulation system with the double central control devices can simulate the actual running state of the train when the master central control device and the slave central control device are switched.
Of course, depending on the needs of the simulation (for example, in the case of simple device model simulation), in one MVB network unit, only one simulation device 10 and one central control device 20 may be provided.
The scope of protection of the present invention is not limited to the specific embodiments disclosed in the above-mentioned embodiments, but only by the combination of technical features of the present invention.
