Detailed Description
The train monitoring system is suitable for one or more of a plurality of monitoring aspects such as safety monitoring, driving control and passenger supervision to the train, when the realization is monitored the train, the train monitoring system of this application can the reduction of the biggest restriction realize the complexity of train control, reduce resource consumption.
For example, referring to fig. 1, a schematic diagram of a component architecture of a train monitoring system of the present application is shown.
As can be seen from fig. 1, the train monitoring system may include:
at least one intelligent general control device 101 arranged on the train;
an information acquisition conversion device 102 is arranged in each carriage of the train;
and a plurality of first-type vehicle-mounted devices 103 provided in each car of the train.
The information acquisition and conversion device 102 is connected to a plurality of first-type vehicle-mounted devices 103 in a compartment where the information acquisition and conversion device 102 is located.
It should be noted that the train mentioned in the present application may be any type of train such as a high-speed rail, a subway, and the like.
The intelligent master control device can be arranged in any carriage of the train.
As an alternative, an intelligent master control device may be respectively disposed in the carriages at the two ends of the train (commonly referred to as the carriages at the train head). For example, a train typically includes a trailer car and a railcar car, where the trailer car refers to the car in which the locomotive providing the tractive power is located in the train. Accordingly, a railcar is a car that is operated by traction power provided by a trailer car, and a railcar is generally a car in the middle of a train, which is a car in which passengers are located and is also a passenger compartment. Of course, there are situations where the trailer car is in the middle of the train. As shown in fig. 1, it is exemplified that trailer cars are disposed at both ends of a train, in which case, an intelligent general control device may be disposed in each trailer car.
It can be understood that if the cars at the two ends of the train are other types of cars, the intelligent general control devices can be arranged in the cars at the two ends. Certainly, in practical application, also can set up the device is always controlled to intelligence in other carriages as required, like no matter which position of trailer carriage in the train, all set up the device is always controlled to intelligence in trailer carriage etc. this application does not add the restriction to this.
The first type of vehicle-mounted equipment is vehicle-mounted equipment without a network interface, that is, vehicle-mounted equipment which needs to be connected with a master control device through an information processing device in the existing train monitoring system. The number and the types of the first type of vehicle-mounted equipment in different compartments may be different. For example, the first type of vehicle-mounted equipment arranged in the trailer compartment can contain a dynamic map display screen for displaying a map, a broadcast console for realizing information broadcast control in a train and the like, but the first type of vehicle-mounted equipment may not be arranged in the common motor car compartment.
Because the first type of vehicle-mounted equipment can not be directly in communication connection with the intelligent master control device in the train through the network, an information acquisition and conversion device capable of connecting the first type of vehicle-mounted wireless equipment with the intelligent master control device is required to be arranged in each carriage. That is, an information acquisition and conversion device and a plurality of first-type vehicle-mounted devices are arranged in a motor car compartment, a trailer compartment or other types of compartments.
However, unlike the existing train monitoring system, in the present application, only one information collecting and converting device 102 needs to be arranged in each car, and a plurality of first-type vehicle-mounted devices in the same car are all connected to the information collecting and converting device 102 in the car, as shown in fig. 1.
The inventor of the application discovers that a plurality of information processing devices are arranged in each car in the prior art through research on the prior train monitoring system, because protocols supported by first-class vehicle-mounted equipment in different vehicle-mounted subsystems have large differences, and the different vehicle-mounted subsystems are independently networked.
In order to realize that only one universal information processing device needs to be arranged in each carriage, only one information acquisition and conversion device 102 is arranged in each carriage, and the information acquisition and conversion device can support conversion among different protocols, so that the information acquisition and conversion device can be compatible with first-class vehicle-mounted equipment of different protocols in the carriages.
Meanwhile, in this embodiment, a train local area network 104 is deployed on the train, the information acquisition and conversion device in each carriage is connected to the train local area network, and the intelligent general control device is also connected to the train local area network.
Correspondingly, the information acquisition conversion device 102 in each carriage can be in communication connection with the intelligent general control device 101 through a train local area network 104 deployed on the train. On this basis, the information acquisition conversion device 102 can realize data transmission and protocol conversion between the plurality of first-class vehicle-mounted devices 101 connected with the information acquisition conversion device 102 and the intelligent general control device. In the process of realizing data transmission, the information acquisition device can also perform format conversion and the like on data transmitted between the first type of vehicle-mounted equipment and the intelligent master control device.
It can be understood that the intelligent master control device can realize the control of all the vehicle-mounted devices in the train, the scheduling and supervision of the train operation, and can also store the data reported by the vehicle-mounted devices, and the like.
For the first type of vehicle-mounted equipment, the intelligent master control device can issue a control command or issue data to the first type of vehicle-mounted equipment, for example, the first type of vehicle-mounted equipment is a display, and can control the working state of the display, and transmit data content to be displayed to the display. The intelligent master control device can transmit data contents such as the control command to the information acquisition and conversion device connected with the first type of vehicle-mounted equipment, and correspondingly, the information conversion device can perform protocol conversion on the data such as the control command and transmit the converted data to the first type of vehicle-mounted equipment according to a protocol supported by the first type of vehicle-mounted equipment.
Similarly, the first type of vehicle-mounted equipment has the reported data which needs to be reported, such as the collected data or the detected equipment fault information, and the like, and the first type of vehicle-mounted equipment transmits the reported data to the information collection and conversion device connected with the first type of vehicle-mounted equipment, and transmits the data to the intelligent master control device after protocol conversion is carried out on the data by the information collection and conversion device.
It should be noted that, under the condition that the intelligent master control devices are arranged in the carriages at the two ends of the train, if the intelligent master control devices are arranged in each of the trailer carriages at the two ends in fig. 1, the information acquisition and conversion device in each of the carriages can communicate with each of the intelligent master control devices and transmit related data.
It can be understood that, the types of the first type of vehicle-mounted devices in the train are more, and the data transmitted by the intelligent master control device and the different first type of vehicle-mounted devices are different, but the protocol conversion can be performed by the information acquisition conversion device and the data transmission can be completed as long as the data transmission exists between the intelligent master control device and the first vehicle-mounted devices, and the application is not limited to the specific content of the specifically transmitted data.
Certainly, the information collecting and converting device may also store some data reported by the first type of vehicle-mounted device, and provide corresponding data to the intelligent main control device when the intelligent main control device accesses the information collecting and converting device.
Meanwhile, similar to the existing information processing device in the train carriage, the information acquisition and conversion device can also perform some simple controls on the first type of vehicle-mounted equipment in the carriage, for example, the first type of vehicle-mounted equipment is controlled according to the command of the intelligent master control device, or the first type of vehicle-mounted equipment is controlled according to actual needs, such as display or data playing.
In the embodiment of the application, the train local area network may be any local area network, as long as the communication between the information acquisition and conversion device and the intelligent master control device in each carriage is realized. For example, the train lan may be an ethernet. The train lan may include a plurality of switches.
Optionally, in order to ensure the safety of data transmission in the train and avoid a failure of a port of a device connected to the train lan or a link where the device is located, which may cause other devices connected to the device to be unable to implement data transmission, the train lan of the present application may be an ethernet ring network established in a link aggregation manner.
On the basis, because the information acquisition conversion devices in all the carriages are connected to the train local area network, the information acquisition conversion devices in different carriages form a ring network, and thus, even if the information acquisition conversion devices break down, the information acquisition conversion devices cannot process data transmitted by first-class vehicle-mounted equipment, the information acquisition conversion devices still have a bypass function, namely the information acquisition conversion devices can realize that the first-class vehicle-mounted equipment connected with the information acquisition conversion devices is connected with the information acquisition conversion devices in other carriages in the train local area network, so that the first-class vehicle-mounted equipment connected with the information acquisition conversion devices can realize data communication with the intelligent master control device through the information acquisition conversion devices in other carriages.
In this embodiment, the train lan has an ability to automatically assign dynamic addresses to devices or apparatuses accessed into the train lan, and the train lan is used to implement fusion and communication between the intelligent master control apparatus on the train, the information acquisition and conversion apparatuses in each carriage, and the first type of vehicle-mounted apparatuses connected to each information acquisition apparatus, and can provide a sub-network separately constructed and deployed for each vehicle-mounted subsystem in the existing train monitoring system. And because the train local area network adopts a link aggregation mode to carry out gigabit Ethernet networking, when a certain port or line in one link in the train local area network has a fault, the transmission can be continued through the other link, and redundant bus connection can be provided by using link aggregation, so that the data bandwidth is increased.
It can be seen that, in the train monitoring system of this embodiment, each train-mounted subsystem is not divided, each carriage is provided with an information acquisition and conversion device, and the information acquisition and conversion device in the carriage is connected to a plurality of first-type train-mounted devices arranged in the carriage, so that the information acquisition and conversion device can realize data transmission and protocol conversion between different first-type train-mounted devices in the carriage and the intelligent master control device arranged in the train, therefore, only one information acquisition and conversion device needs to be arranged in one carriage to realize data communication between the first-type train-mounted devices and the intelligent master control device, and different information processing devices need not to be arranged separately for the first-type train-mounted devices with different protocol types in the carriage, and because the information processing devices can directly communicate and interact with the intelligent master control device without arranging branch control devices in each carriage, therefore, resource consumption and train space occupation caused by repeated arrangement of the same type of equipment in each carriage can be reduced.
Meanwhile, because the train is provided with the train local area network, the information acquisition and conversion device in each carriage can realize data communication with the intelligent master control device through the train local area network, thereby avoiding the independent network arrangement aiming at different vehicle-mounted subsystems in each carriage and reducing the complexity and resource consumption of train monitoring.
It can be understood that the vehicle-mounted device disposed in the vehicle compartment may have one or more second type vehicle-mounted devices, typically a plurality of second type vehicle-mounted devices, besides the first type vehicle-mounted device which does not have a network interface (e.g., an ethernet interface) and needs to communicate with the intelligent general control device through the information acquisition and conversion device. The second type of vehicle-mounted equipment is equipment which has a network interface (such as an Ethernet interface) and can directly communicate with the intelligent master control device through a network without an information acquisition and conversion device.
For ease of understanding, reference may be made to fig. 2, which is a schematic diagram illustrating a structure of a train monitoring system according to another embodiment of the present disclosure.
As can be seen from fig. 2, in the train monitoring system, in addition to the aforementioned information acquisition and conversion device 102 and the first-type on-board device 103 connected to the information acquisition and conversion device, a plurality of second-type on-board devices 105 are provided in each car. For example, the second type of vehicle-mounted device 105 may be a network camera IPC, a brake control unit BCU, or the like vehicle-mounted device.
Wherein each second type vehicle-mounted device 105 is connected to the train local area network 104.
Correspondingly, each second-type vehicle-mounted device 105 can be in communication connection with the intelligent general control device 101 through the train local area network 104. It can be understood that, based on the communication connection between the second type of vehicle-mounted device and the intelligent master control device, the data transmission between the second type of vehicle-mounted device and the intelligent master control device 101 can be realized, for example, the second type of vehicle-mounted device reports the data acquired, generated or detected by the second type of vehicle-mounted device to the intelligent master control device; the intelligent master control device can also transmit control commands and some data needing to be displayed or output and the like to the second type of vehicle-mounted equipment through the train local area network.
For example, when the second type of vehicle-mounted device is a brake control unit, the brake control unit may report data related to train braking to the intelligent master control device, and may perform control related to braking according to a control command issued by the intelligent master control device.
Of course, the data interacted between different types of second-type vehicle-mounted equipment and the intelligent master control equipment also has a large difference.
It can be understood that in any embodiment of the above train monitoring system, one or more sensors that need to interact with the intelligent general control device through the information acquisition and conversion device may be further disposed in the train car, but cannot be directly connected to the information acquisition and conversion device due to the interface type display. In order to enable the sensors of different types to be connected with the information acquisition and conversion device, the sensors can be connected into the front processing unit and then connected with the information acquisition and conversion device through the front processing unit.
Still referring to fig. 2, it can be seen from fig. 2 that at least one preprocessing unit 106 connected with the information acquisition and conversion device is further disposed in each car of the train, and at least one sensor is connected to each preprocessing unit. As shown in fig. 2, a temperature sensor, a vibration sensor, and the like are connected to one pre-processing unit of the trailer compartment.
Wherein the types of sensors provided in different compartments may also differ. For example, the types and numbers of sensors contained within the trailer compartment and within the railcar compartment may vary.
The front-end processing unit is provided with a plurality of interfaces matched with the sensors of different types, so that the front-end processing unit can be compatible with the sensors of different interface types. For example, some sensors are type 01 interfaces, some sensors are ethernet interfaces, and the front-end processing unit can be provided with the two types of interfaces at the same time, so that the sensors can access the appropriate interfaces.
Correspondingly, the front-end processing unit can also be used for realizing the communication protocol conversion between the sensor connected with the front-end processing unit and the information acquisition and conversion device.
Specifically, the front-end processing unit can manage various sensors in a carriage so as to realize the switching of analog channels of measurement objects such as temperature measurement, vibration and the like; and the analog signals are transmitted in a bus or Ethernet mode.
It can be understood that, because the train monitoring system in the present application is configured to be integrated with each device on the train through the train lan, in order to ensure that the device or device accessing the train lan is an authorized legal device, the train monitoring system in the embodiment of the present application may further include: at least one authentication intelligent control device arranged in the train. Wherein, an authentication intelligent control device is arranged in each carriage provided with the intelligent master control device. For example, an intelligent authentication master control device can be arranged in the carriages (head carriages) at the two ends of the train.
For example, as shown in fig. 2, an authentication intelligent control device 107 is further provided in the trailer compartment.
The authentication intelligent control device 107 accesses the train lan 104.
The intelligent authentication control device 107 is used for verifying the legitimacy of devices and equipment in the train accessing the train local area network. For example, the authentication intelligent control device may be responsible for port control, data verification in network transmission, and the like.
It can be understood that if the train monitoring system only includes some on-board devices or equipment on the train, it is not beneficial to know the train operation status timely and effectively, and to store the relevant data collected on the train. Optionally, for more reasonable train monitoring, the train monitoring system of the present application may further include: and a ground control center.
In order to enable the ground control center to monitor the train more efficiently, the ground control terminal can be built in a cloud platform. Fig. 3 is a schematic diagram illustrating another structure of the train monitoring system according to the present invention.
As can be seen from fig. 3, the train monitoring system includes an intelligent general control device 101 disposed on the train; an information acquisition conversion device 102 is arranged in each carriage of the train; the train control system comprises a plurality of first-type vehicle-mounted devices 103 arranged in each compartment of a train, a train local area network 104 deployed on the train, and a ground control center built and operated on a cloud platform 108.
The cloud platform can comprise one or more cloud servers, and part or all of resources can be divided by the cloud platform to serve as resources required by the operation of the ground control center. The cloud platform can be a private cloud platform or a public cloud platform, the cloud platform can support load balancing, corresponding resources are reasonably allocated to application needing big data technical analysis to carry out assistance enhancement processing, the problem that the resources cannot be shared mutually in a traditional mode is solved, and the data processing efficiency of a ground control center is improved.
In order to realize the communication between the intelligent master control device and the ground control center, in this embodiment, the intelligent master control device further includes a communication board, for example, a wireless rf module and the like includes a communication board for realizing the wireless communication function. Correspondingly, the intelligent master control device can send the data of the set type to the ground control center through the communication board card train.
It can be understood that, in order to ensure the communication between the intelligent communication device and the ground control center, the intelligent master control device is also connected with an antenna, and the antenna is connected with a communication board card of the intelligent master control device. Correspondingly, the intelligent communication master control device can realize data interaction with the ground control center through the communication board card and the antenna.
It can be understood that, in the running process of the train, the intelligent master control device can obtain the data reported by all the devices and equipment on the train and control all the devices and equipment, and in order to enable the ground control center to know the running and safety conditions on the train in time, the intelligent master control device can send some obtained key data to the ground control center. If the data types required to be reported to the ground control center by the intelligent master control device can be preset, the intelligent master control center can report the data belonging to the data types to the ground control center.
It can be understood that the ground control center can also send data to the intelligent general control device, such as control instructions, prompt information to be played to passengers, or some information for reminding train drivers or crew members, etc. The intelligent master control device can receive data sent by the ground control center through the communication board card.
A ground control center is established based on a cloud platform, and information interaction between the ground control center and an intelligent master control device can enable each monitoring system to flexibly acquire related data, so that data interaction is more frequent and convenient, and real-time processing and data display delay are effectively reduced.
In order to conveniently and timely check the train related monitoring data obtained by the ground control center, the train monitoring system further comprises display equipment connected with the ground control center, such as a cloud desktop for displaying monitoring pictures and the like, and display equipment such as a mobile phone, a personal computer and the like.
It can be understood that a ground maintenance center and a data center for assisting a ground control center in train control or realizing train-related data storage can be further constructed on the cloud platform.
It can be understood that, because the device is always controlled to device and equipment in the whole car of train needs to be managed and control to intelligence, the data volume that needs to handle is great in the train operation process, consequently, in order to avoid disturbing the intelligent device of always controlling to train operation and safety control, simultaneously, can report the relevant data that produce in the train again for ground control center, can also include in the train monitored control system of this application: the authentication intelligent control device 107 is provided in the train, and in the present embodiment, a wireless access point 109 is further connected to the authentication intelligent control device.
Specifically, the intelligent master control device for authentication can be arranged in a carriage provided with the intelligent master control device, and the intelligent control device for authentication in the same carriage is connected with the intelligent master control device.
