Example 1
Fig. 1a is a flowchart of a method for detecting a signal device of a train control system according to an embodiment of the present application, where the method may be performed by a signal device detection apparatus of the train control system, and the signal device detection apparatus of the train control system may be implemented in hardware and/or software, and the signal device detection apparatus of the train control system may be configured in an electronic device. As shown in fig. 1a, the method comprises:
s110, receiving a current state data packet sent by the signal equipment, and determining the current receiving time of the current state data packet.
The signal equipment is equipment for providing running information for the vehicles, and can command the running of the vehicles through the signal equipment and ensure the running safety of the vehicles. The number of signal devices is at least one. In the application, the vehicle can be a rail train, and the signal equipment is rail traffic signal equipment. Optionally, the signaling device comprises at least one of: TSRS equipment, RBC equipment, and TIS equipment. Among them, the TSRS device (Temporary Speed Restriction Server, temporary speed limit service) provides necessary speed limit management control capability for safe operation of the train. RBC device (Radio Block Center, wireless block center) is a computer and its mating equipment for traffic engineering field. The TIS device (Train Control Center And Interlocking Integrated System, train control integrated device) can realize station interlocking and section blocking integrated control.
The current state data packet refers to a state data packet sent by the signal device received by the signal device detection system at the current moment. The status data packet is a data packet formed after the signal device packages the data representing the status information. The current status data packet corresponds to the signaling device. The receiving time is the time when the signal equipment detecting system receives the state data packet, and correspondingly, the current receiving time refers to the time when the signal equipment detecting system receives the current state data packet.
According to the application, the detection of the running state information of the signal equipment can be realized by receiving the current state data packet sent by the signal equipment through the signal equipment detection system, and the on-site staff is timely reminded to process when the signal equipment fails. When the signal equipment detection system receives the current state data packet, the current receiving time of the current state data packet is determined. It will be appreciated that the number of current status data packets is at least one, i.e. the current status data packets transmitted by at least one signaling device may be received simultaneously by the signaling device detection system. The signaling device may continuously transmit the status data packets according to a preset period.
Optionally, the signal device may send the status data packet through a UDP network transport protocol (User Datagram Protocol, user data packet protocol), which reduces the transmission overhead of sending the status data packet, and is applicable to the case of periodically sending the status data packet.
It can be appreciated that, according to a plurality of railway signal devices deployed by a railway, the signal device detection system automatically acquires status data packets of the TIS device, the TSRS device, and the RBC device and monitors the operation status of each signal device. Before automatically acquiring the status data packet of the signal device, the basic information of each signal device needs to be configured. Specifically, the basic information of the signal device includes at least a device number, a device type, a device network address, a device transmission data port, and the like. The signal device detection system may add the basic information of the signal device to the database to enable configuration of the basic information of the signal device. Multiple signal device basic information of multiple different types, such as 6 TIS devices, 1 TSRS device and 2 RBC devices, can be added to the database. Taking a signal device as an example, basic information of a TIS signal device in a station includes: the device ID is configured as "109349377", the device type is "TIS", the device IP is "192.150.83.28", the port number is "18013", and the like. Since each signal device has uniqueness, after the basic information of the signal device is configured, the signal device detection system cannot be confused among a plurality of signal devices monitored by the signal device detection system, and the monitoring of the operation condition of the signal devices is completely independent.
After the basic information configuration of each signal device is completed, the signal device detection system periodically receives the status data packet sent by each signal device by setting the network address and the port where each signal device is located. Specifically, for each signal device, a status data packet of the signal device can be received, which indicates that the connection with the signal device is successful, and the signal device is running; the status data packet of the signal device cannot be received, which indicates that the connection with the signal device fails and the signal device operates abnormally.
S120, analyzing the current state data packet of the signal equipment to acquire the current state information and the current data packet information of the current state data packet.
The status information is data generated when the signal device is operated. Correspondingly, the current state information refers to data generated when the signal equipment at the current moment runs, and can represent the running state of the signal equipment at the current moment.
Optionally, the current state information includes at least one of: device alarm information and device data information. The device alarm information refers to alarm information generated when signal devices fail, and exemplary device alarm information can be classified into 1-level alarm information, 2-level alarm information, 3-level alarm information, and the like. Specifically, the level of the device alarm information may be divided according to a preset rule. The device data information is used for representing data of the signal device for controlling the running behavior of the vehicle. It is also understood that specific driving requirements are provided for the vehicle by means of the device data information. Wherein the device data information includes at least one of: TSRS speed limit data, RBC vehicle data, and TIS line data. The TSRS speed limit data is used for representing the speed limit requirement on the train running speed, and the TSRS speed limit data is exemplified as the highest speed per hour of 30km/h. RBC vehicle data refers to information characterizing train conditions. TIS route data refers to information characterizing the route traveled by the vehicle.
The data packet information is data generated in the process of packaging the status data packet by the signal equipment. The current data packet information refers to data generated in the process of packaging the current state data packet by the signal equipment at the current moment, and is used for representing the information of the current state data packet.
Optionally, the current packet information includes at least one of: device type, device number, packing time, packet number, etc. Wherein the device type refers to the type of the signal device. By way of example, the device type may be a signal and transponder, etc. The device number is used to distinguish between different signal devices, which have unique device numbers. It will be appreciated that the device numbers of any two signal devices may be different, and the device types of any two signal devices may be the same or different. The TSRS1 device and the TSRS1 device are both TSRS devices, the TSRS1 device has a device number of equal to:. 50. The packing time refers to the time when the signaling device packs the current state data packet. The packet sequence number refers to the sequence number of the current state data packet sent by the signaling device.
Specifically, after receiving the current state data packet, the signal equipment detection system analyzes the current state data packet to obtain an analysis result. And acquiring the current state information and the current data packet information included in the current state data packet from the analysis result.
S130, determining the running state and the abnormality reason of the signal equipment according to the current state information, the current data packet information and the current receiving time.
The operating state of the signal device is used to characterize whether the signal device is operating properly. The operating state of the signaling device may include normal operation and abnormal operation. The reason for the abnormality is used to characterize the reason for the abnormal operation of the signal device. The number of causes of the abnormality is at least one. Each abnormality cause corresponds to a judgment condition set in advance. The field staff can repair the signal equipment in time according to the abnormal operation reasons.
Specifically, comparing the current state information, the current data packet information or the current receiving time with preset judging conditions of abnormal reasons, and determining that the running state of the signal equipment is abnormal running and determining the abnormal reason when the judging conditions of any abnormal reason are met.
For example, the abnormal cause is memory overflow, a packet stacking accident occurs, and the corresponding judgment condition is that the difference between the packing time and the current receiving time in the current packet information is greater than a threshold value. And under the condition that the difference between the packing time and the current receiving time in the current data packet information is larger than a threshold value, determining the running state of the signal equipment as abnormal running, determining the abnormal reason as memory overflow, and generating a data packet stacking accident. And under the condition that the difference between the packing time in the current data packet information and the current receiving time is smaller than or equal to a threshold value, determining the running state of the signal equipment to be normal running.
In another example, the abnormality is a device failure, and the corresponding judgment condition is that the current state information has device alarm information therein. And under the condition that the current state information contains equipment alarm information, determining that the running state of the signal equipment is abnormal running, and determining that the cause of the abnormality is equipment fault. And under the condition that the current state information does not contain equipment alarm information, determining the running state of the signal equipment to be normal running.
According to the technical scheme, the current receiving time of the current state data packet is determined by receiving the current state data packet sent by the signal equipment, the current state information and the current data packet information in the current state data packet are acquired by analyzing the current state data packet of the signal equipment, the running state of the signal equipment is determined according to the current state information, the current data packet information and the current receiving time, and when the running state of the signal equipment is abnormal, the abnormal reason is determined, so that the automatic detection of the signal equipment is realized, meanwhile, the abnormal reason of the signal equipment can be determined through the current state data packet, the intellectualization and convenience of the detection of the signal equipment of a train control system are improved, the detection efficiency of the signal equipment is improved, and the manual workload is reduced.
In one embodiment, the parsing the current state data packet of the signal device to obtain current state information and current data packet information of the current state data packet includes: decoding and checking the current state data packet of the signal equipment; under the condition of successful verification, analyzing the packet header of the current state data packet to acquire the current data packet information; and analyzing the information packet content in the current data packet information to obtain the current state information.
When the signal equipment packs the current state data packet, the signal equipment can encrypt the current state data packet, and before the signal equipment detection system analyzes the current state data packet, the signal equipment detection system needs to decode and check the current state data packet first. The successful verification indicates that the data packet received by the signal equipment detection system is the current state data packet. An unsuccessful verification indicates that the data packet received by the signal device detection system is not a current state data packet or that the current state data packet is in error. The current state data packet at least comprises a packet head part and a packet tail part. In the application, the current state data packet can be encrypted through CRC (Cyclic redundancy check ), wherein the packet tail is a CRC code used for decoding and checking the current state data packet.
And under the condition of successful verification, analyzing the packet header of the current data packet, wherein the obtained analysis result is the current data packet information. The current packet information includes at least one packet content. And further analyzing the information package to obtain an analysis result of the content of the information package, namely the current state information.
Fig. 1b is a schematic diagram of a data packet and an information packet according to a first embodiment of the present invention. Fig. 1b shows a UDP 16-ary byte code packet, which is transmitted and received according to a packet coding rule agreed between the signal device detection system and the signal device. The signal device performs data transmission according to the data packet rule shown in fig. 1b, and the signal device detection system performs data reception according to the data packet coding rule shown in fig. 1 b. And after the signal equipment detection system receives the data packet, checking the data packet according to a CRC check rule. Under the condition of successful verification, the packet header of the current data packet is analyzed to obtain the current data packet information, namely the equipment type, the equipment number, the time (packing time), the packet serial number, the total number of the information packets, the position of the information packets in the group, the information content length, the information content and the like. The analysis result of the information package content, namely the version number, the content length, the information type, the translation plaintext and the like, is obtained by further analyzing the information content (the information package content) in the current data package information. It can be understood that the plaintext translation needs to be explained according to code bits agreed by a protocol, which is a byte code bit table agreed by the signal device detection system and the signal device. Exemplary: byte 1 is a device type, where 1 represents a TIS device, 2 represents a TSRS device, and 3 represents a RBC device. Byte 2 is the device number, etc. Meanwhile, the content of the data packet has different meanings according to the protocol specification, and the method is exemplified: the RBC device 2409 protocol specification data packet contains effective contents such as train running information, train number (e.g. 0x 18273612), train running direction (e.g. forward direction), train length (e.g. 400 m), train speed (e.g. 72 km/h) and the like; the RBC device 2010 protocol specification data packet contains the active contents of device alert information, alert device (e.g., RBC device), alert sub-device (e.g., RBC host device), alert description (e.g., connection with adjacent TSRS interrupt), alert class (class 1), etc.
The decoding and verification are carried out on the current state data packet of the signal equipment, under the condition that the verification is successful, the packet head of the current state data packet is analyzed, the current data packet information is obtained, the current state data packet can be ensured not to be invaded, and the safety of the current state data packet is improved.
