Known via above-mentioned technical scheme, compared with prior art, the present invention openly provides a kind of changing method, mobile unit and switched system of mobile unit car controlling power.The current mobile unit that has car controlling power is to treating that car controlling mobile unit sends car controlling enable signal.Treat that car controlling mobile unit receives car controlling enable signal, and judge whether self possesses car controlling condition, and will show that the car controlling status signal that possesses car controlling condition is sent to the current mobile unit that has car controlling power.When car controlling status signal represents when car controlling mobile unit possesses car controlling condition, the current mobile unit that has car controlling power is to treating that car controlling mobile unit sends car controlling power switching signal, switches to car controlling power to treat car controlling mobile unit; When car controlling status signal represents when car controlling mobile unit does not possess car controlling condition, the current mobile unit that has car controlling power does not carry out car controlling power and switches, and the current mobile unit that has car controlling power continues car controlling.With respect to existing car controlling power switching mode, in the present invention, only have when having the mobile unit of car controlling power and determine just can carry out the switching of car controlling power when car controlling mobile unit possesses car controlling condition, thereby guarantee that when different mobile unit car controllings power is switched train is all subject to the control of mobile unit, prevent from, because the reasons such as signal transmission errors cause train not generation of controlled situation when mobile unit car controlling power is switched, having improved the safety of train operation when mobile unit car controlling power is switched.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments of the invention, for those of ordinary skills, do not paying under the prerequisite of creative work, other accompanying drawing can also be provided according to the accompanying drawing providing.
Fig. 1 shows the schematic flow sheet of the changing method of a kind of mobile unit car controlling power of the present invention;
Fig. 2 shows the structural representation of an embodiment of a kind of mobile unit car controlling power of the present invention switched system.
The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
In order to express easily, in following examples, the current used for vehicle-carrying equipment mobile unit A that has car controlling power represents, treats that car controlling used for vehicle-carrying equipment mobile unit B represents.
Referring to Fig. 1, show the schematic flow sheet of the changing method of a kind of mobile unit car controlling power of the present invention.
As shown in Figure 1, the method comprises:
101: mobile unit A sends car controlling enable signal to mobile unit B.
102: mobile unit B receives car controlling enable signal, and output shows whether mobile unit B possesses the car controlling status signal of car controlling condition.
After mobile unit B receives the car controlling enable signal of mobile unit A transmission, mobile unit B detects the car controlling condition of self, and testing result is sent to mobile unit A.
It should be noted that, when testing result shows that mobile unit B possesses car controlling condition, mobile unit B sends and is used to indicate the car controlling status signal that mobile unit B possesses car controlling condition to mobile unit A;
When testing result shows that mobile unit B does not possess car controlling condition, mobile unit B sends and is used to indicate the car controlling status signal that mobile unit B does not possess car controlling condition to mobile unit A.Optionally, this car controlling status signal can adopt low and high level.When mobile unit B possesses car controlling condition, mobile unit B is to mobile unit A output high level signal, and when mobile unit B does not possess car controlling condition, mobile unit B is to mobile unit A output low level signal.
103: when mobile unit A receives mobile unit B and possesses the car controlling status signal of car controlling condition, to mobile unit B, send car controlling power switching signal, car controlling power is switched to mobile unit B.
104: when mobile unit A receives mobile unit B and do not possess the car controlling status signal of car controlling condition, mobile unit A continues car controlling.
It should be noted that, when mobile unit A not to mobile unit B send car controlling enable signal but receive from mobile unit B output possess the car controlling status signal of car controlling condition time, mobile unit A judges that this situation is abnormal, no longer car controlling power is switched to mobile unit B.
As can be seen here, in the present invention, only have when having the mobile unit of car controlling power and determine just can carry out the switching of car controlling power when car controlling mobile unit possesses car controlling condition, thereby guarantee that when different mobile unit car controllings power is switched train is all subject to the control of mobile unit, prevent from, because the reasons such as signal transmission errors cause train not generation of controlled situation when mobile unit car controlling power is switched, having improved the safety of train operation when mobile unit car controlling power is switched.
It should be noted that, the invention also discloses a kind of mobile unit.When this mobile unit is during as current car controlling mobile unit, be mainly used in to treating that car controlling mobile unit sends car controlling enable signal, response treats to treat whether car controlling mobile unit possesses the car controlling status signal of car controlling condition described in being used to indicate of car controlling mobile unit feedback, control carry out car controlling power switching whether.
When this mobile unit is when until car controlling mobile unit, when car controlling power is switched, this mobile unit, for responding the car controlling enable signal of the mobile unit transmission that has car controlling power, treats whether car controlling mobile unit possess the car controlling status signal of car controlling condition described in being used to indicate to the described mobile unit output that has car controlling power.
This mobile unit comprises: train control on board equipment, train operation monitoring and recording device, orbital motion safety control, subject highlighting locomotive control device and/or other can be controlled the car-mounted device of train operation.
Referring to Fig. 2, show the structural representation of an embodiment of a kind of mobile unit car controlling power of the present invention switched system.
This system mainly comprises: currently have the mobile unit A of car controlling power and treat car controlling mobile unit B.
Mobile unit A is in car controlling state, due to driver manually or line condition change triggers carry out car controlling power while switching, mobile unit A output car controlling enable signal is to mobile unit B.Mobile unit B receives car controlling enable signal, according to self whether possessing car controlling condition, to mobile unit A, sends car controlling status signal.Mobile unit A receives the car controlling status signal that mobile unit B sends, if car controlling status signal represents mobile unit B, possesses car controlling condition, and mobile unit A is switched to mobile unit B by car controlling power, and mobile unit B controls train; If car controlling status signal represents mobile unit B and does not possess car controlling condition, mobile unit A continuation car controlling.
Between mobile unit signalling methods comprise any one in digital signal level, MVB bus, Profibus bus, CAN bus, FlexRay bus, serial ports and/or ethernet.。
