Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure. While the invention will be described in connection with the preferred embodiments, there is no intent to limit its features to those embodiments. On the contrary, the invention is described in connection with the embodiments for the purpose of covering alternatives or modifications that may be extended based on the claims of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The invention may be practiced without these particulars. Moreover, some of the specific details have been left out of the description in order to avoid obscuring or obscuring the focus of the present invention.
As described above, the existing train high-voltage electrical monitoring technology does not have the function of displaying the real-time state of the bus disconnector to the train driver in time, and is not favorable for the train driver to make a reasonable judgment and execute a correct operation by combining the real-time state of the bus disconnector.
In order to make up for the above defects in the prior art, the invention provides a prompting method of the state of a bus isolating switch, a prompting device of the state of the bus isolating switch and a computer readable storage medium, which are used for monitoring the working state and the switching state of the bus isolating switch in real time and prompting the state of the bus isolating switch to train drivers and related workers by means of pop-up window control at the first time, thereby ensuring the driving safety of a train.
In some non-limiting embodiments, the method for prompting the state of the bus disconnecting switch can be implemented by a device for prompting the state of the bus disconnecting switch. Specifically, the bus bar disconnecting switch state prompting device can comprise a memory and a processor. The memory may include a computer-readable storage medium having stored thereon computer instructions. The processor is connected with the memory and is configured to execute the computer instructions stored in the memory so as to implement a prompting method for the state of the bus disconnecting switch.
The following will implement some embodiments of the bus disconnecting switch state prompting method in combination with some bus disconnecting switch state prompting devices. It will be appreciated by persons skilled in the art that these embodiments are merely provided as non-limiting examples of the invention, and are intended to clearly illustrate the broad concepts of the invention and to provide some convenient embodiments for the public, and not to limit the scope of the invention.
Referring to fig. 1, fig. 1 is a flow chart illustrating a method for prompting a state of a bus disconnector according to some embodiments of the present invention.
As shown in fig. 1, the method for prompting the state of the bus disconnector provided by the invention may include the steps of: and monitoring an overcurrent fault signal and a switch state signal of the bus isolating switch by utilizing a terminal device arranged in a train marshalling.
In some non-limiting embodiments, the method for prompting the state of the bus disconnecting switch can be implemented based on a network control system of a CRH2 type series motor train unit. A network control system (hereinafter referred to as MON system) of CRH2 type series motor train units is a distributed control system, and generally adopts a combination of centralized acquisition, train-level control and vehicle-level control. The train-level bus generally adopts an optical fiber ring network, adopts an ANSI/ATA-878.1(ARCNET) protocol, and is provided with an HDLC bus for controlling the backup transmission of instructions.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating an architecture for detecting a bus bar disconnector status based on a MON system according to some embodiments of the present invention.
As shown in fig. 2, in the above embodiment, the bus bar disconnecting switch may be provided at the fourth consist of the eight-consist train. In some preferred embodiments, the processor of the bus bar disconnector status indication device may control a fourth car terminal device 10, also arranged in the fourth consist of the train, to monitor the bus bar disconnector for an overcurrent fault signal and a switch status signal. By monitoring the state of the bus disconnecting switch by using the fourth vehicle terminal device 10 arranged in the same grouping, the length of a signal detection line can be effectively shortened, the energy loss is reduced, the electromagnetic crosstalk is avoided, and the acquisition instantaneity of overcurrent fault signals and switch state signals is improved.
In some embodiments, the fourth vehicle terminal device 10 may include a hard-wired IO interface 11, a control instruction receiving module 12, an optical signal transmission module 13, and a terminal processor (CPU3) module 14. Specifically, the hard-line IO interface 11 may be optically coupled to a bus isolation switch through a hard line M756 to collect an overcurrent hard-line signal. This hard wire IO interface 11 can also be through hard wire M757 opto-coupler connection bus isolator to gather switch hard wire signal.
Referring further to fig. 3, fig. 3 is a schematic diagram illustrating a principle of hard-line monitoring of the status of a bus disconnector according to some embodiments of the present invention.
As shown in fig. 3, one end of each of the hard wires M756 and M757 is connected to the bus bar isolator, and the other end thereof is connected to the corresponding channel of the hard wire IO interface 11 through an optical coupler, and is adapted to output a 24V optical coupler signal to the corresponding channel of the hard wire IO interface 11 when the optical coupler is turned on. In some embodiments, the hard-wired IO interface 11 will only receive a signal input when the difference between the positive and negative terminals of the optocoupler reaches 4V or more.
Taking the hard wire M756 as an example, when the hard wire M756 is not turned on, the potential of the M756 wire is 24V, no voltage difference or current flows across the input end of the optical coupler, and the optical coupler is not turned on. On the contrary, when the M756 line is turned on, the potential of the M756 line drops to about 20V or lower, a potential difference of more than 4V is generated at two ends of the input end of the optocoupler, so that a current flows through the optocoupler and the optocoupler is turned on, and an M756 signal is generated to the control instruction receiving module 12 through the hardwired IO interface 11. The signal acquisition principle of the hard wire M757 is the same as that of the hard wire M756, and will not be described herein.
As shown in fig. 2, the control command accepting module 12 is electrically connected to the hardwired IO interface 11, and is adapted to convert a low voltage differential signal clock input (RXC) signal provided by the hardwired IO interface 11 into an interactive data packet (RM) and send the interactive data packet (RM) to the optical signal transmitting (MDM8) module 13. In some embodiments, if there is a signal input to hardwires M756 and M757, the RXC module 12 sends a signal "1" to the MDM8 module 13; conversely, if there is no signal input to hardwires M756 and M757, the RXC module 12 sends a signal "0" to the MDM8 module 13.
The optical signal transmission (MDM8) module 13 is communicatively connected to the train-level ring network bus of the MON system, and is adapted to provide a network signal conforming to the ARCNET protocol to the train-level ring network bus according to the RM packet provided by the RXC module 12. The processor of the bus disconnecting switch state prompting device can perform ring network data exchange with the MDM8 module 13 through a train-level ring network bus, and obtain ring network data to judge an overcurrent fault signal and a switch state signal. In some embodiments, the processor of the bus bar disconnector status prompting device may be served by the CPU3 module 24 of the central device 20. The CPU3 module 24 can utilize the MDM8 module 23 of the central device 20 to exchange ring network data with the MDM8 module 13 of the fourth vehicle terminal device 10, so as to determine the overcurrent fault signal and the switch status signal of the bus disconnector according to the received ring network data.
The terminal processor (CPU3) module 14 may be communicatively connected to the MDM8 module 13 of the present group, and is adapted to perform logic determination according to the RM packet data and ring network data acquired by the MDM8 module 13. In some embodiments, the terminal processor (CPU3) module 14 of the fourth in-vehicle terminal device 10 may determine the over-current fault signal and the switch status signal of the bus bar disconnector from the RM packet data provided by the MDM8 module 13. The CPU3 module 24 can utilize the MDM8 module 23 to perform ring network data exchange with the MDM8 module 13, and directly obtain the determination results of the overcurrent fault signal and the switch state signal from the CPU3 module 14.
It will be appreciated by those skilled in the art that the above-described scheme for monitoring the over-current fault signal and the switch state signal of the bus disconnector based on the MON system of the CRH2 type train is only a non-limiting example provided by the present invention, and is intended to clearly illustrate the main concept of the present invention and provide some specific schemes for facilitating the public implementation without limiting the scope of protection of the present invention. Optionally, in other embodiments, a person skilled in the art may also design a corresponding scheme based on the above concept of the present invention and based on a network control system of another train, so as to achieve the effect of monitoring an overcurrent fault signal and a switch state signal of the bus disconnector.
As shown in fig. 1, the method for prompting the state of the bus disconnecting switch provided by the present invention may further include the steps of: and responding to the overcurrent fault signal, and displaying an overcurrent fault window on a display of the cab at the main control end.
In some embodiments of the invention, in response to the start of the train network control system, the processor of the bus isolator state prompt device may operate therewith to monitor the bus isolator for an over-current fault signal and a switch state signal. In general, the bus disconnecting switch state prompting device can start to operate after 10s of starting of the train network control system.
In response to detecting that the M756 signal is "0" and lasts for more than 0.5s, the processor can judge that the bus disconnecting switch has an overcurrent fault, so that a fault prompt pops up on the displays of each train cab and the mechanic's cab, and the train drivers and other related staff are guided to process. In some embodiments, the fault notification described above may be implemented based on display pop-up control techniques of the MON system. Specifically, the processor can further pop up an overcurrent fault window on the existing display interface of the display to prompt the train driver that the bus disconnecting switch has overcurrent fault.
Referring to fig. 4A and 4B, fig. 4A is a schematic diagram illustrating an over-current fault window according to some embodiments of the present invention, and fig. 4B is a schematic diagram illustrating an over-current fault interface according to some embodiments of the present invention.
As shown in fig. 4A, in some embodiments, in response to detecting that the M756 signal is "0" and lasts for more than 0.5s, the processor may further pop up an over-current fault window on an existing display interface (e.g., a driving status interface) of the display. The overcurrent fault window can mark the position of the fault and explain the fault content, thereby prompting a train driver that the bus disconnecting switch of the fourth marshalling has the overcurrent fault. It is understood that the over-current fault window is a pop-up window which is displayed on the existing display interface in an overlapping manner. In some embodiments, in response to the M756 signal again being a "1", the processor may determine that the over-current fault signal is off, thereby automatically closing the over-current fault window to again display the contents of the driving status interface therebelow.
In some preferred embodiments, the over-current fault window may further include a fault detail button and a page delete button. After reading the fault condition, the train driver can click the page delete button to close the over-current fault window, and can also click the fault detail button to further know how to handle the fault. In response to the train driver clicking the fault detail button, the processor may close the existing display interface to further display an over-current fault interface on the display of the master cab.
As shown in fig. 4B, the over-current fault interface may include fault content information and processing measure information. The fault content information can indicate the position of the fault and explain the fault content to prompt a train driver that the bus disconnecting switch of the fourth marshalling has an overcurrent fault. The processing measure information can gradually instruct drivers how to carry out fault processing according to the specific switch state of the bus isolating switch so as to ensure the driving safety of the train. In some embodiments, the over-current fault interface may also include a return button. The train driver can return to the previous display interface (i.e., the driving state interface) by clicking the return button.
Optionally, in some embodiments, in response to detecting that the M756 signal is "0" and lasts for more than 0.5s, the processor may further illuminate a main fault indicator light of the train and a unit indicator light of the bus disconnector overcurrent fault to prompt a train driver.
In some embodiments of the invention, the display of the cab may include a switchboard information interface. Train drivers can inquire the switch state of the bus isolating switch through the switchboard information interface.
Referring to fig. 5A and 5B, fig. 5A is a schematic diagram of a switchboard information interface when a bus disconnector provided according to some embodiments of the present invention is open, and fig. 5B is a schematic diagram of a switchboard information interface when a bus disconnector provided according to some embodiments of the present invention is closed.
As shown in fig. 5A and 5B, the switchboard information interface may include a plurality of car tags. Each compartment tag corresponds to a train consist, and may include status icons of a plurality of devices such as a bus disconnector of the train consist. The train driver can open the switchboard information interface to inquire the switch state of the bus disconnector. In response to the M757 signal changing from "1" to "0" (filtering for 0.5s), the processor may determine that the bus isolator is open, thereby displaying the status icon of the bus isolator as a white word with red background. Conversely, in response to the M757 signal changing from "0" to "1" (filtering for 0.5s), the processor may determine that the bus isolator is closed, thereby displaying the status icon of the bus isolator as a black word with green background.
As shown in fig. 1, the method for prompting the state of the bus disconnecting switch provided by the present invention may further include the steps of: and responding to a switch state signal indicating that the bus disconnecting switch is disconnected, displaying a bus disconnecting switch disconnection prompting window on a display of the cab at the main control end, and requiring a driver to confirm.
As described above, in response to the M757 signal changing from "1" to "0" (filtered 0.5s), the processor may determine that the bus disconnector is open. Different from the overcurrent fault window, the prompt information of the disconnection of the bus isolating switch must be known by a train driver and is personally confirmed by the train driver, so that the driving safety of the high-speed train can be fully guaranteed. Therefore, the processor of the bus disconnecting switch state prompting device can pop up a bus disconnecting switch disconnection prompting window on the existing display interface of the display of the master control end cab and ring a 5-second buzzer to prompt a train driver to check confirmation. In addition, even if the M757 signal is changed from '0' to '1' (filtering for 0.5s) again, namely the bus isolating switch is closed again, the processor does not automatically close the bus isolating switch opening prompting window, but the bus isolating switch opening prompting window is required to be closed after the train driver confirms the bus isolating switch in person.
In some embodiments of the present invention, the train may be a two-way train, and may include two locomotives. Each locomotive can be provided with a cab. The two drivers' cabs are respectively positioned at two ends of the train. The train driver can select a key for switching in the cab of any locomotive to activate the cab as the cab of the main control end, and the train is controlled to run in the corresponding direction in the activated cab of the main control end. Correspondingly, in response to the M757 signal being changed from "1" to "0" (filtering for 0.5s), the processor may first determine the master control-end cab of the train according to the activation signal of the cab, and then send an instruction to display the bus disconnector disconnection prompting window to the display of the master control-end cab.
In some preferred embodiments, the display of each cab of the train may include a primary screen and a secondary screen. In response to the M757 signal being changed from "1" to "0" (filtering for 0.5s), the processor may first acquire display interface data of the display main screen of the cab at the main control end to determine whether the display interface thereof belongs to a predefined exclusion interface. The exclusion interfaces include, but are not limited to, a link-de-link related interface, an initial selection interface, a driver menu interface, a trainee menu interface, and a record menu interface. Compared with prompt information of disconnection of the bus disconnecting switch, the exclusion interfaces are more important and urgent for driving judgment of train drivers. Therefore, the driving safety of the train can be further ensured by excluding the exclusion interfaces.
If the display interface of the main display screen of the cab at the main control end does not belong to the exclusion interface, namely belongs to other common interfaces, the processor can further display a bus disconnecting switch disconnection prompting window in an overlapping manner on the existing interface (such as a driving state interface) of the main display screen. The bus isolator disconnection prompt window can be realized based on a display popup control technology of an MON system. On the contrary, if the display interface of the display main screen of the main control end cab belongs to the exclusion interface, the processor can judge that the display main screen cannot display the disconnection prompting window of the bus disconnecting switch at present, so that the disconnection prompting window of the bus disconnecting switch is further displayed on the existing interface of the display auxiliary screen of the main control end cab in an overlapped mode.
It will be appreciated by those skilled in the art that the above-described scheme for determining whether the main screen of the display is available based on the current display interface of the main screen of the display is only a non-limiting example provided by the present invention, and is intended to clearly illustrate the main concept of the present invention and provide some convenient and specific schemes for the public to implement, but not to limit the scope of the present invention. Optionally, in other embodiments, the processor may also display a bus disconnecting switch disconnection prompting window by using the secondary screen in the case that other primary screens are unavailable, such as a primary screen is disconnected, a primary screen failure, and the like.
Referring to fig. 6, fig. 6 is a schematic diagram illustrating a disconnection prompting window of a bus bar disconnecting switch according to some embodiments of the present invention.
As shown in fig. 6, in some embodiments, the bus bar disconnector disconnection prompting window may include operation prompting information and attention information. The operation prompt message can be used for guiding a driver how to operate after the bus disconnecting switch is disconnected. The train driver can know the current state of the bus disconnecting switch by reading the operation prompt information and learn how to perform the next operation under the current condition. By adopting the bus isolating switch disconnection prompting window to prompt the bus isolating switch state to the train driver and guiding the train driver to perform the next operation, the train driver can ensure the driving safety of the train no matter whether the train driver is trained by related faults or not.
As described above, even if the M757 signal changes from "0" to "1" (filtering for 0.5s) again, that is, the bus disconnector is closed again, the processor does not automatically close the bus disconnector opening prompt window, but the bus disconnector opening prompt window needs to be closed after the train driver confirms himself. In the embodiment shown in fig. 6, the bus bar disconnector opening prompt window may further comprise a confirmation button. The train driver can close the bus disconnecting switch disconnection prompting window by clicking the confirmation button.
Referring to fig. 7, fig. 7 is a schematic flow chart illustrating closing of a bus disconnecting switch disconnection prompting window according to some embodiments of the present invention.
As shown in fig. 7, in some embodiments, if the master control right of the cab of the train is switched (for example, the master control cab is switched from the first cab in the first consist to the second cab in the eighth consist), and the train driver does not confirm the prompt message of the disconnection of the bus isolation switch, the processor may remove the confirmation button of the disconnection prompt window of the bus isolation switch in the first cab, and display the disconnection prompt window of the bus isolation switch including the confirmation button on the display of the second cab. At this time, anyone including the train driver can not confirm the prompt information in the first cab, but only can go to the second cab by the train driver to click the confirmation button for confirmation, so as to ensure that the prompt information of the disconnection of the bus disconnecting switch is known by the train driver. And then, responding to the fact that the train driver clicks the confirmation button in the second cab, the processor can judge that the prompt information of disconnection of the bus disconnecting switch is known by the train driver, so that the disconnection prompt windows of the bus disconnecting switches of the first cab and the second cab are synchronously closed, and the content of the running state interface below the disconnection prompt windows is displayed.
In some embodiments, the bus disconnecting switch disconnection prompting window of the non-master-side cab can be manually closed. Specifically, in response to the first cab losing ownership, the processor may determine that the train driver is not present in the first cab. In response to the display of the first cab entering the service mode or the diagnostic mode, the processor may close the bus disconnector disconnection prompting window of the first cab to display the content of the service interface or the diagnostic interface. And then, if the display of the first cab is switched back to the common mode again, the disconnection prompting window of the bus isolating switch can not pop up any more.
In some embodiments, if the master control right of the cab of the train is further switched, that is, the cab at the master control end is switched back to the first cab in the first consist again from the second cab in the eighth consist, and the train driver still does not confirm the prompt message of the disconnection of the bus disconnecting switch, the processor may display the confirmation button again on the bus disconnecting switch disconnection prompt window of the first cab, and remove the confirmation button of the bus disconnecting switch disconnection prompt window of the second cab. At this time, anyone including the train driver can not confirm the prompt information in the second cab, but only can go to the first cab by the train driver to click the confirmation button for confirmation, so as to ensure that the prompt information of the disconnection of the bus disconnecting switch is known by the train driver.
