fig. 2 is a flowchart of a block chain based ATS distributed control method according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
In the related technology, for a centralized ATS system, in actual operation, all ATS service data in the whole line are concentrated in central ATS processing, so that the system processing pressure is high, meanwhile, the system safety is ensured to be too single only by relying on one-master-one-slave dual-computer hot-standby redundancy, once the central ATS cannot work, the whole line operation is influenced, the key service information can be tampered by modifying the central ATS system information, the safety is poor, and huge economic loss is easily caused.
In order to solve the above problem, an embodiment of a first aspect of the present invention provides an ATS distributed system based on a block chain, and the ATS distributed system can improve the safety and stability of a track entire signal system, and avoid causing economic loss.
A block chain based ATS distribution system according to an embodiment of the present invention is described below with reference to fig. 1.
As shown in fig. 1, the block chain-based ATS distribution system 10 includes a plurality of ATS, each of which is disposed at a station of a target line, the plurality of ATS form a block chain based on a preset consensus mechanism, and the plurality of ATS are all used as block chain nodes in the block chain.
The ATS at each block link point is used for receiving local service information sent by trains in the jurisdiction area and ground systems, sending the local service information to the ATS at other block link points in the block chain according to a preset intelligent contract, acquiring shared service information sent by the ATS at other block link points in the block chain, verifying the shared service information, and storing the shared service information when the ATS at the block link points exceeding the preset number passes the verification of the shared service information.
The local service information or the shared service information may include train position, train operation direction, train plan information, train communication mode, train operation mode, route open state, route automatic trigger attribute, route conflict information, current day plan information, actual departure information, jump stop information, train holding information, passenger clearing information, gating strategy, and the like.
The preset intelligent contract comprises the steps of outputting a digital signature after inputting the local service information and the private key, and outputting the accuracy of data after inputting the shared service information, the digital signature and the public key.
In the embodiment, as a block chain technology establishes a 'trust' network between machines by applying a set of consensus-based mathematical algorithm, so as to create a brand-new credit through a technical endorsement rather than a centralized credit mechanism, the embodiment of the invention deploys the ATS system by using a chain structure of a block chain, that is, the ATS distributed system 10 establishes a 'trust' network between ATS systems at various stations by applying a set of consensus-based mathematical algorithm, so as to ensure the correctness of data by using the characteristic technologies of a plurality of block chain nodes, instead of upgrading the original centralized ATS system into a decentralized and multi-node-protected ATS distributed system, thereby ensuring the safety of rail transit operation and improving the stability and safety of the whole signal system of a rail.
Specifically, an ATS is correspondingly set at each station of a target line, the ATS at each station is used as a node of a block chain, when each ATS receives local service information sent by a train and a ground system in a controlled area, the local service information is sent to a corresponding block chain link point, the corresponding block chain link point initiates a block chain data updating instruction in real time according to the change of the local service information, and broadcasts the local service information to other block chain nodes in the block chain according to a preset intelligent contract. Meanwhile, any block link point can acquire shared service information sent by ATSs (automatic transfer system) of other block link points, so that when any ATS stops working, the whole-line normal operation can still be ensured through the block link points, the safety and stability of the whole signal system of the track are improved, and the economic loss is avoided.
In addition, when any block chain node acquires the shared service information, the shared service information is verified, and when ATS at the block chain link points exceeding the preset number passes the verification of the shared service information, the shared service information is stored, so that the shared service information of the block chain nodes can be synchronized to the block chain link points of the whole line. Specifically, after the consensus mechanism of the block chain has limited that more than a preset number of block chain link points are judged by a preset intelligent contract, the whole block chain can verify that the shared service information is correct, any block chain node can directly adopt the shared service information, otherwise, the shared service information is abnormal node error data, the block chain node can automatically shield the abnormal node error data to prevent the problem of misjudgment of access opening or wrong calculation of the safety distance of the train caused by adopting wrong ground data or train data, and therefore, the service information in the block chain can be tampered only when the verification is accurate and the verification limiting conditions are met, the integrity, authenticity and safety of the data can be ensured, the hidden danger of intentionally controlling and modifying the train information can be avoided, the safety and stability of the whole signal system of the track are improved, and the possibility of information tampering is reduced.
For example, as shown in fig. 1, an ATS distributed system 10 based on a block chain includes six ATS, the six stations form a train line, that is, a target line, the block link point ATS 1 at the station 1 adds a private key to local service information, obtains a digital signature through a preset intelligent contract, and further sends the local service information and the digital signature to the block link points ATS at other stations, the block link nodes ATS at other stations perform calculation verification on the digital signature, the local service information, and a public key through the preset intelligent contract, and if the verification is reliable, the local service information is stored, otherwise, if the verification is unreliable, corresponding measures such as alarm prompt are performed, and the local service data is not stored.
According to the block chain-based ATS distributed system 10 of the embodiment of the invention, the ATS is correspondingly arranged at each station on the target line, the block chain nodes corresponding to each ATS are combined into the block chain based on the preset consensus mechanism, the ATS at each block chain node receives the local service information and simultaneously acquires the shared service information of other block chain nodes, so that the whole line can still normally operate when any ATS stops working, the operation safety is ensured, the safety and stability of the whole signal system are improved, the economic loss is avoided, the shared service information is verified by the ATS at each block chain node, and the shared service information is stored only when the shared service information is verified by the ATS at the block chain nodes exceeding the preset number, so that the integrity, authenticity and safety of data can be ensured, and the problem that the service information is tampered can be avoided.
In some embodiments, the preset number is half of the number of the block chain nodes in the block chain, that is, the consensus mechanism of the block chain limits that more than half of the block chain nodes are required to verify that the shared service information is correct, and the whole block chain can determine that the shared service information is correct, so that under the conditions of more stations and more block chain link numbers in the whole system, an illegal user cannot grasp and tamper more than half of the block chain nodes in the block chain, thereby ensuring the integrity, authenticity and safety of data, preventing the illegal user from arbitrarily manipulating and modifying train information, improving the safety and stability of the whole signal system of the track, and reducing the possibility of information tampering.
In some embodiments, due to the commonality of the block chains, the ATS of each station maintains the service information of the all-wire ATS, and therefore, when it is determined that an ATS at any one block link point in the block chain has a fault, the ATS at the non-faulty block link point takes over the monitoring tasks of the trains and ground systems in the area under the jurisdiction of the ATS at the faulty block link point.
That is to say, on the premise that a ground system and a train in an area contained by a block chain do not have a fault, when a block chain node in the block chain cannot operate due to an emergency stop or an ATS crash of the train, the ground system and the local service information of the train in the area governed by the faulty block chain node can be transmitted to the ATS at the non-faulty block chain link point, the ATS at the non-faulty block chain link point replaces the operation of the ATS at the faulty block chain link point, and the train in the area governed by the ATS at the faulty block chain link point and the ground system communicate with each other, so as to process an access development signal in real time to control the train operation, thereby ensuring the normal operation of the whole line, therefore, the embodiment of the invention adds a layer of protection measures to the block chain distributed system based on the block chain by combining all the block chain nodes in the block chain together, and even if only one distributed ATS in the block chain operation system 10 based on the block chain has a distributed ATS, the whole operation system can still ensure the normal operation of the safety signal loss of the whole distributed system, and thus the safety loss of the whole distributed system can be avoided.
In some embodiments, determining that the ATS at any one of the tile link points in the tile chain is malfunctioning comprises at least one of: the ATS at any block chain link point cannot be successfully sent to ATS local service information at other block chain link points in the block chain; the ATS at any block chain link point cannot successfully analyze the received shared service information sent by the ATSs at other block chain link points in the block chain; the service information of the ATS analysis at any block link point is inconsistent with the result of the ATS analysis at other block link points in the block chain.
In some embodiments, the ATS at each block link point is further configured to generate an all-wire train network topology map of the target link according to the local traffic information and the shared traffic information, and display the all-wire train network topology map.
Specifically, ATSs arranged at each station on a target line jointly form a block chain, all route opening information, train information and turnout information in each station are independently recorded by an original centralized ATS system and are changed into common records of the ATSs at all block chain link points in the block chain, namely, all stations can acquire service information such as train information, route information, track section information, signal machine information and the like of the whole line, so that each station can independently and accurately judge the service information such as train running condition, track information, passenger flow information and the like of the whole line to generate a whole line train network topological diagram, and the effect of displaying all stations of the whole line information in real time is achieved.
Therefore, based on the all-line train network topological diagram which can be displayed in real time at each station, the passengers can conveniently check the real-time position information of all trains on the all line, the speed of the trains, the maximum safe distance, the minimum safe braking distance, the number of all passengers of the trains, the number of passengers in each carriage, the real-time occupation state and fault state of the track section, the pre-arrival time of the next station of the trains or the passenger flow information of the stations and other service information through the multimedia screen arranged at the station or the multimedia screen in the trains, so that the passengers can know the conditions of the all-line tracks and the trains in real time, the problem that the passengers are in confusion due to the temporary stop of sudden accidents is avoided, and the safety of the passengers is improved. Meanwhile, the passengers can also know the conditions of the next station arrival time of the train, the passenger flow information of the station and the like in real time through the displayed whole-line train network topological graph, so that the passengers can adjust the carriages taking the train by themselves, the condition that the passenger flow in the carriages is seriously unbalanced is avoided, and the riding comfort of the passengers is improved.
For example, each station on the target line records all-line train information, the multimedia screen in each station displays the number of passengers in each carriage in all the trains about to enter the station within five minutes, and based on the information, the passengers with the train in the station can automatically adjust the positions of queuing and getting on the train, so that the problem that the passengers are excessively concentrated in a certain carriage to influence the riding experience is avoided. And when the train runs and needs to temporarily stop due to the congestion of the head-line train, the running train can initiate the in-train broadcasting in advance and synchronously display the congestion reason and situation of the head-line train on a multimedia screen of the train, so that passengers can know the details of the abnormal situation of the train through audio and video to avoid the panic problem.
In some embodiments, since the whole line information is shared in the whole block chain, and the structure of the block chain ensures the trustiness of the information, the ATS at each block link point is further used for marking a failed block chain node in the whole line train network topology map and giving an alarm to prompt abnormal information of the failed block chain node when determining that the ATS at any one block link point fails, that is, the ATS at all block link points in the block chain can realize an abnormal automatic alarm to prompt related personnel to handle the failure condition in time, and meanwhile, the problem of misjudgment of the open route or wrong calculation of the train safety distance due to the adoption of wrong ground data or train data is prevented.
Specifically, the ATS at each block link point in the block chain realizes the capability of information self-verification, transmission and management and decentralization, that is, any one block chain node has the capability of processing all-line service information, and each block chain node also stores all-line service information. Therefore, when the service information is inconsistent, under the condition of no central control, a plurality of block chain nodes participate in decision making to achieve consensus, so that correct service information can be identified, and each block chain node in the block chain only adopts correct service information; and for the identified wrong service information, the source of the wrong service information can be traced back to position the ATS corresponding to the specific block chain link point, the abnormity of the block chain link point is identified in the network topological graph of the whole-line train, and the abnormity of the block chain node is prompted by an alarm, so that the abnormal node error data can be automatically shielded, the problem of misjudgment caused by the adoption of wrong ground data or train data is prevented, and the abnormity automatic alarm can be realized, so that related personnel can be prompted to timely handle the fault condition.
The block chain based ATS distributed system according to the embodiment of the present invention is described in detail below by taking a train service information early warning as an example, and the specific content is as follows.
Referring to fig. 1, it is assumed that the block link point ATS 1 at the station 1 reports local service information as follows: train a at station 1, train B at station 2, and train C at station 3. If the ATS network of the station 1 delays for 1 minute, the ATS blocks local service information within one minute, so that when the local service information and the digital signature are sent to block chain nodes ATS of other stations through a private key of the station 1 and a preset intelligent contract, the service information of other block chain nodes is told that the service information of the train A is still at the station 1, the train B is at the station 2 and the train C is at the station 3. However, the traffic data of the other blockchain nodes is up to date, and the records are that train a has left station 1, train B has left station 2, and train C has left station 3. Under the condition, when other block link nodes receive local service information and digital signatures of a station 1 at which a train a is located, a station 2 at which a train B is located, and a station 3 at which a train C is located, which are sent by a block link node at the station 1, the local service information sent by the block link node at the station 1 is analyzed through a preset intelligent contract and a public key, and the local service information is found to be inconsistent with service information stored by other block link nodes that the train a has left the station 1, the train B has left the station 2, and the train C has left the station 3, so that the service information in the above steps can obtain verification results of the ATS of other block link nodes based on a pre-stored common identification mechanism in the stations 1 to 6, and under the structure of one node of the block chain, the service information in the above steps can obtain the verification results of the ATS of other block link nodes through the preset intelligent contract, that the local service information sent by the block link node ATS 1 is judged to have errors, and the problem that the ATS 1 cannot reliably store the local service information of the block link node is considered, and the safety problem that the ATS 1 may exist.
Furthermore, if the network of the block link point ATS 1 of the station 1 recovers to be normal after a period of time, the local service information of the block link point ATS 1 is resynchronized according to the service information of other block link nodes, and the subsequent local service information also recovers to be normal. Meanwhile, when other block chain nodes receive the local service information of the recovered block chain node ATS 1, and the service information of the other block chain nodes is determined to be consistent with the service information of the other block chain nodes through the digital signature, the preset intelligent contract and the public key, the previous alarm information is cancelled, and all the service information of the block chain node ATS 1 is synchronized.
In summary, in the block link based ATS distributed system provided in the embodiment of the present invention, corresponding block link nodes are set for ATS of all stations on a target line and combined into a block link, shared service information is generated according to local service information sent by the block link nodes and an intelligent contract pre-stored in the block link nodes and sent to each block link node, so as to verify and protect data, and an early warning can be sent according to the accuracy of the service information and corresponding measures can be taken, so that the safety and reliability of a track whole signal system are improved, and the limitation of a centralized ATS system is avoided.
An embodiment of a second aspect of the present invention provides an ATS distributed control method based on a block chain, where the ATS distributed control method is used in an ATS distributed system, the ATS distributed system includes multiple ATS, each ATS is set at a station of a target line, the multiple ATS form the block chain based on a preset consensus mechanism, and the multiple ATS are all used as block link points in the block chain, as shown in fig. 2, and the control method at least includes step S1 and step S2.
Step S1, the ATS at each block chain link receives local service information sent by the trains in the jurisdiction area and the ground system, and sends the local service information to the ATS at other block chain links in the block chain according to a preset intelligent contract.
And S2, the ATS at each block link point acquires the shared service information sent by the ATSs at other block link points in the block chain, verifies the shared service information, and stores the shared service information when the ATSs at the block link points exceeding the first preset number pass the verification of the shared service information.
According to the block chain-based ATS distributed control method provided by the embodiment of the invention, ATSs are correspondingly arranged at each station on a target line, block chain link points corresponding to each ATS are combined into a block chain based on a preset consensus mechanism, the ATS at each block chain link point receives local service information and simultaneously acquires shared service information of other block chain nodes, so that the whole line can still normally operate when any ATS stops working, the operation safety is ensured, the safety and stability of the whole signal system of a track are improved, the economic loss is avoided, the shared service information is verified by the ATS at each block chain link point, and the shared service information is stored only when the shared service information is verified by the ATSs at the block chain link points exceeding the preset number, so that the integrity, the authenticity and the safety of data can be ensured, and the problem that the service information is tampered can be avoided.
In some embodiments, because the common characteristics of the block chains are that the ATS of each station stores the service information of the all-line ATS, when it is determined that the ATS at any one block link point in the block chain has a fault, the ATS at the block link point that has not failed takes over the monitoring tasks of the train and the ground system in the area under the control of the ATS at the faulty block link point. Therefore, on the premise that a ground system and a Train in an area contained by a block chain are not in fault, even if a certain block chain node in the block chain is in fault, local service information of the ground system and the Train in the area governed by the fault block chain node can be transmitted to an ATS at a block chain link point without fault, and the ATS at the block chain link point without fault replaces the Operation of the ATS at the block chain link point with the Operation of the ATS at the fault block chain link point, so that other block chain link points can continue to make a corresponding Operation plan according to a Train number matched with a table number, so as to send an access processing instruction to the ground system and send an ATO (Automatic Train Operation) control instruction to the Train, further take over the Train and the ground system in the area governed by the fault block chain node, and display an access open signal and Train information in real time to ensure the normal Operation and display of the whole line, thereby, the embodiment of the invention can ensure that the safety loss of the whole distributed ATS is increased by combining all the block chain nodes in the block chain, and even if one distributed ATS is added to the distributed type of the distributed ATS, the whole ATS, the distributed protection system can be used for preventing the whole ATS, and increasing the whole ATS.
In some embodiments, the control method further comprises: and the ATS at each block link point generates a full-line train network topological graph of the target line according to the local service information and the shared service information, and displays the full-line train network topological graph.
Specifically, ATSs arranged at each station on a target line jointly form a block chain, all route opening information, train information and turnout information in each station are independently recorded by an original centralized ATS system and are changed into common records of the ATSs at all block chain link points in the block chain, namely, all stations can acquire service information such as train information, route information, track section information, signal machine information and the like of the whole line, so that each station can independently and accurately judge the service information such as train running condition, track information, passenger flow information and the like of the whole line to generate a whole line train network topological diagram, and the effect of displaying all stations of the whole line information in real time is achieved.
