Fig. 2 is a schematic flow chart of a train anti-skid method provided in an embodiment of the present application, where an execution subject of the method may be the ground host 101 in fig. 1, as shown in fig. 2, the method may include:

step S201, when an arrival request sent by vehicle-mounted equipment of the locomotive is received, obtaining a station track identifier in the arrival request, wherein the station track identifier is used for indicating a station track where the locomotive is to stop.

The wireless shunting locomotive signal and monitoring system is important driving safety equipment for ensuring the safety of station shunting operation. The system generally comprises a ground part and a vehicle-mounted part, wherein in the embodiment of the application, the ground part is a ground host computer, and the vehicle-mounted part is vehicle-mounted equipment.

In order to distinguish each station track, a unique number can be assigned to each station track, and the number is the track identification of the station track. According to the track identification, one track can be uniquely determined, and information such as the position of the track is obtained.

Specifically, when the locomotive needs to stop at an arrival station, an arrival request can be sent to the ground host computer through the vehicle-mounted equipment on the locomotive, and the arrival request comprises a station track identifier of a station track where the locomotive is to stop. After receiving the station entering request, the ground host acquires the station track identifier in the request, acquires the station track where the locomotive is to stop according to the station track identifier, and determines the information of the station track in the subsequent steps so as to determine whether to allow the locomotive to enter the station.

And step S202, sending a skate position query request to a skate OPC server through an OPC security gateway, wherein the skate position query request comprises the station track identifier, so that the skate OPC server responds to the skate position query request to acquire the position information of each skate on the station track corresponding to the station track identifier, and the position information of each skate is reported to the skate OPC server through the skate wireless gateway of each skate.

The traditional ground station (dispatching station) system and the iron shoe server system belong to systems with different control levels, and the communication safety between industrial control subsystems with different control levels needs to be ensured. In the prior art, for the above safety consideration, only a ground station (dispatch station) system is allowed to send a simple request instruction to a skate server system, and the skate server system feeds back the position information of all the skates in the station yard to the ground station (dispatch station) in response to the simple request instruction. That is, the two systems in the prior art do not allow finer information interaction.

In order to solve the defects, a security gateway (firewall) and the like are arranged in the data transmission process between two systems. In other words, the OPC security gateway is added between the ground host and the skate server, the skate server is adapted to be the skate OPC server, and the interaction between the ground host and the skate OPC server is completed through the OPC security gateway.

The opc (ole for Process control) technology is used to establish an interface standard for communication between applications of the industrial control system, and to establish a uniform data access specification between the industrial control device and the control software. The standard data access mechanism is provided for the field of industrial control, hardware and application software are effectively separated, the standard data access mechanism is a set of software data exchange standard interface and procedure which are irrelevant to manufacturers, the problem of data exchange between a process control system and a data source of the process control system is mainly solved, and transparent data access can be provided among various applications. The skate OPC server is used for receiving and storing data collected by various sensors in the skate and reported by the skate wireless gateway, and can perform some preprocessing on the received data.

Specifically, after receiving an entry request sent by a vehicle-mounted device of the locomotive, the ground station sends an iron shoe position query request to an iron shoe OPC server through an OPC security gateway, wherein the iron shoe position query request comprises the track identifier, and the purpose of sending the request is to acquire the position information of the iron shoe in the track corresponding to the track identifier quickly. Specifically, after receiving the skate position query request, the skate OPC server may obtain position information of each skate in the track corresponding to the track identifier from each skate wireless gateway. And after receiving the position information, the skate OPC server packages the position information into UDP data packets and sends the UDP data packets to the ground host. The packing into UDP packets facilitates the physical isolation of the network.

And step S203, receiving the position information of each skate fed back by the skate OPC server through the OPC security gateway, and sending a corresponding control instruction to the vehicle-mounted device based on the position information of each skate and the station track identifier.

Specifically, after receiving the position information of each skate fed back by the skate OPC server, that is, receiving the UDP data packet sent by the skate OPC server, the ground host analyzes the UDP data packet to obtain the current position information of each skate. And further determining whether the track corresponding to the track identification is provided with the iron shoe or not according to the position information of the iron shoe. And further determining whether the track where the locomotive is to stop is provided with the iron shoes. And finally, the ground host generates a control instruction for the locomotive according to whether the track where the locomotive is to stop is provided with the iron shoes and the specific positions of the iron shoes on the track, and sends the control instruction to the vehicle-mounted equipment, so that the safe entry of the locomotive is ensured, and the 'shoe pressing' accident is avoided.

And S204, after receiving the parking in-place information sent by the vehicle-mounted equipment, sending a skate state query request to a skate OPC server at intervals of a preset time period through an OPC security gateway, wherein the skate state query request comprises position information of the head and the tail of the locomotive, so that the skate OPC server responds to the skate state query request to acquire state information of each skate between the head and the tail of the locomotive, and the state information of each skate is reported to the skate OPC server by a skate wireless gateway of each skate.

Specifically, after the locomotive enters a station and stops in place, the locomotive is in a static state, iron shoes are arranged at the head and the tail of the locomotive for anti-slipping, and the state of the iron shoes needs to be monitored later. After receiving the in-place parking information sent by the vehicle-mounted equipment, the ground host determines that the monitoring of the state of the skate needs to be started. Specifically, the ground host sends a skate status query request to a skate OPC server at intervals of a preset time period through an OPC security gateway, and the purpose of sending the request is to acquire status information of each skate between the locomotive head and the locomotive tail (i.e., status information of each skate for preventing the locomotive from slipping). Specifically, the skate OPC server may obtain the status information of each skate from the skate wireless gateway of each skate between the locomotive head and the locomotive tail after receiving the skate status query request. After receiving the state information, the skate OPC server packages the state information into UDP data packets (for network physical isolation) and sends the UDP data packets to the ground host.

And step S205, receiving the state information of each skate fed back by the skate OPC server through the OPC security gateway, and performing anti-skid control on the train based on the state information of each skate.

Specifically, after receiving the state information of each skate fed back by the skate OPC server, namely receiving a UDP (user Datagram protocol) data packet sent by the skate OPC server, the ground host analyzes the UDP data packet to obtain the current state information of each skate, judges whether the skate is normal or not according to the state information of each skate, and further controls the anti-sliding of the train.

It should be noted that, in the locomotive station entering control process, it is only necessary to determine whether the track where the locomotive is to stop is provided with the skate or determine the position of the skate on the track where the locomotive is to stop, and then the ground host only needs to acquire the carried position information and does not need the state information of the skate in the control process, so that only the position information of the skate is acquired. In the locomotive anti-slip monitoring process, only the state information of the anti-slip iron shoes arranged aiming at the locomotive is required to be obtained, and the position information is not required, so that only the state information of the iron shoes is obtained. Obviously, according to the scheme, the information of the iron shoes transmitted between the ground host and the iron shoe OPC server is distinguished according to the requirements of different scenes, namely only the position information of the iron shoes is transmitted in the station entering control process, only the state information of the iron shoes is transmitted in the anti-slip monitoring process, and compared with the prior art that the position information and the state information of the iron shoes are not distinguished in each transmission process and all scenes are transmitted simultaneously, the scheme not only saves network resources, but also ensures the real-time property of transmission.

The utility model provides a scheme, at the locomotive control process of coming to the station, through the position information who acquires each skate confirm whether be provided with the skate on the station track that the locomotive will stop, and then whether confirm the locomotive and go to the station and whether will carry out the skate and demolish work, at the locomotive stop the swift current monitoring stage of preventing behind target in place, the state information through acquireing each skate carries out the train and prevents the swift current control, this scheme is compared in prior art and mainly has the following several beneficial effects in the aspect: on the one hand, in the scheme, the ground host can communicate with the iron shoes through the iron shoe wireless gateway in the implementation process, and then the ground host can issue instructions to the iron shoes in time and receive data collected by the iron shoes, so that the communication is simple and the real-time performance is strong. On the other hand, the scheme distinguishes the transmission information of the iron shoes in two different scenes of a locomotive station entering control process and a locomotive anti-slip monitoring stage, namely only the position information of the iron shoes is obtained but not the state information in the station entering control process, and only the state information of the iron shoes is obtained but not the position information in the anti-slip monitoring stage, so that not only is network resources saved, but also the real-time property of transmission is ensured. On the other hand, in the scheme, an OPC security gateway is added between the ground host and the skate OPC server, so that the communication security between the industrial control subsystems of two different management and control levels of a traditional ground station (dispatching station) system and the skate OPC server system is ensured.

and if the position information of each skate indicates that no skate is arranged on the track corresponding to the track mark, sending a station entering instruction to the vehicle-mounted equipment.

Specifically, the ground host computer may determine whether the locomotive can stop on a track to which the locomotive is to stop after receiving the position information of the skate on the track. If it is determined that no skate is located on the track at which the locomotive is to be parked (i.e., the track corresponding to the track identification), then it is assumed that the locomotive may enter the track parking without the risk of "pressing shoes". Therefore, the ground host generates a corresponding control instruction for indicating the locomotive to enter the station, and sends the control instruction to the vehicle-mounted equipment of the locomotive, and the vehicle-mounted equipment executes the control instruction and then the train enters the station and stops. If it is determined that the track where the locomotive is to stop is provided with the iron shoes, the locomotive enters the station and stops possibly with the risk of pressing the shoes, at the moment, the ground host can transmit an iron shoe removing instruction to a station locomotive inspector, the station inspector removes the iron shoes on the track according to the iron shoe removing instruction and then feeds back that the iron shoes of the ground host are removed, the ground host generates a corresponding control instruction for indicating the locomotive to enter the station and sends the control instruction to the vehicle-mounted equipment of the locomotive, and the vehicle-mounted equipment executes the control instruction and then the train enters the station and stops.

Further, if it is determined that the track where the locomotive is to stop is provided with the iron shoes, it may be further determined that the iron shoes are located at the specific position of the track, and according to a pre-stored stop length range of the locomotive on the track, if it is determined that the iron shoes on the track are located within the stop length range, it is determined that a "shoe press" risk exists, a field station locomotive inspector is required to remove the iron shoes, if it is determined that the iron shoes on the track are located outside the stop length range, it is determined that the "shoe press" does not exist, and the ground host may generate a control instruction to instruct the locomotive to stop at the entering station. The method can reduce manual participation as much as possible and further improve the efficiency of the inbound control process.

Specifically, in the skate monitoring process, if the state information of the skate does not contain alarm information, the condition that the skate anti-slipping state is in a normal state when the skate state is collected is indicated. If the skate state information contains alarm information, the skate anti-sliding state is in an abnormal state when the skate state is collected, at the moment, the ground host needs to transmit a skate detection instruction to a station locomotive inspector, the station locomotive inspector inspects the states of all the skates according to the instruction, and corresponding processing is carried out until the anti-sliding state is recovered to the normal state.

In an optional embodiment of the present application, the method may further comprise:

and if the state information of each iron shoe fed back by the iron shoe OPC server is received for the preset times and remains unchanged, sending an iron shoe sensor sleep instruction to the iron shoe OPC server, so that the iron shoe OPC server responds to the iron shoe sensor sleep instruction and sends a specified sensor closing instruction to each iron shoe through the iron shoe wireless gateway of each iron shoe.

Specifically, as can be seen from the foregoing description, if the received state information of the skate does not include the alarm information, it is determined that the anti-slip state carried at the receiving time is in the normal state. Then, when the state information of each skate received by the preset times continuously keeps unchanged, and no alarm information is contained in the state information, the skate is indicated to be in a stable normal state, wherein the specific numerical value of the preset times can be set according to experience and actual requirements. In order to reduce the power consumption of the iron shoe and prolong the service life of the iron shoe, part of sensors in the iron shoe can be turned off. Specifically, the ground host sends a skate sensor sleep command to the skate OPC server, indicating the type of sensor that needs to be turned off. It is understood that the type of sensor that needs to be shut down, indicated in the sensor sleep command, can be set as desired. After receiving the sensor dormancy instruction, the iron shoe OPC server sends an appointed sensor closing instruction to the iron shoe wireless gateway of each iron shoe on a station track where the locomotive stops, and after the iron shoe wireless gateway forwards the appointed sensor closing instruction to the corresponding iron shoe, the iron shoe closes the sensor of the corresponding type, so that the purpose of reducing the power consumption of the iron shoe is achieved.

Wherein, be provided with multiple sensor and loRa communication module on the skate, various data are gathered as the perception layer to multiple sensor on the skate for confirm the position and the state of skate, also be provided with loRa communication module on the skate wireless gateway that corresponds, realize the communication between skate and the corresponding skate wireless gateway through loRa communication module, including the transmission of various data. In addition, still be provided with data processing module on the skate wireless gateway, can handle the data that various sensors that the skate reported to the police are gathered, this processing procedure can confirm whether the data that each sensor of skate gathered is normal, if abnormal then add corresponding alarm information.

Further, when the train stops in place, in order to reduce the power consumption of the iron shoes, the power consumption of the sensors in the iron shoes can be turned off, and particularly, all the sensors except the attitude sensor can be turned off. In addition, when data collected by some closed sensors needs to be acquired, the ground host computer can send a sensor awakening instruction to the skate OPC server, and the skate OPC server responds to the instruction and sends a specified sensor opening instruction to each skate through the skate wireless gateway of each skate.

Further, the skate OPC server responds to the skate state query request, and acquires the state information of each skate between the locomotive head and the locomotive tail, wherein the state information comprises the following steps:

Specifically, the skate OPC server employs a high concurrency communication mode, which may be Netty. After receiving an inquiry request sent by a ground host, the EPC server generates a corresponding information acquisition instruction according to the request content, determines and determines information sources (the information sources are the iron shoes on a station track where a locomotive stops in the locomotive station entering control process, and the information sources are all working iron shoes in the anti-skid monitoring process), then respectively sends the information acquisition instruction to the iron shoe wireless gateways of the iron shoes corresponding to the information sources, and the iron shoe wireless gateways forward the information acquisition instruction to the corresponding iron shoes which report corresponding information according to the information acquisition instruction.

Fig. 3 is a block diagram of a train anti-skid device according to an embodiment of the present disclosure, and as shown in fig. 3, the device 300 may include: an inbound request receiving module 301, a skate position query request sending module 302, an inbound control module 303, a skate state query request sending module 304 and a train anti-skid control module 305, wherein:
