Technical Field

At the present stage, the AFC system generally consists of four hierarchical architectures, namely, a device level (such as a gate, an automatic ticket vending machine, and a manual ticket vending machine), a station level, a line level, and a road network level, and when data of a station terminal is collected, the AFC system generally needs to report the data of the station terminal step by step. However, the gradual reporting method takes a long time (for example, ten minutes), which results in poor real-time performance of monitoring the station terminal. In addition, each station terminal can only collect data in the AFC system according to a fixed collection mode, for example, the running state data of the station terminal is only reported to the line center computer system and is stopped, and is not reported to the multi-line center computer system, so that the multi-line center computer system cannot know the running state of each station terminal, and thus, the existing AFC system has poor flexibility in monitoring the station terminal.

In summary, a solution for centralized supervision of each station terminal in the AFC system is needed to improve flexibility and real-time performance of supervision of the station terminal.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Fig. 1 is a schematic diagram of a system architecture of a conventional urban rail transit system, which may be an Automatic Fare Collection (AFC) system. As shown in fig. 1, the AFC system includes a multi-line center computer system 110, a line center computer system 120, a station center computer system 130, and a station terminal 140 arranged hierarchically. The multi-line center computer system 110 is connected to the line center computer system 120, the line center computer system 120 is connected to the station center computer system 130, and the station computer system 130 is connected to the station terminal 140, for example, the multi-line center computer system may be connected by a wired manner, or may be connected by a wireless manner, which is not limited specifically.

In the embodiment of the invention, the station terminal can be any AFC operation terminal, such as an automatic ticket vending machine, an automatic ticket checking machine (gate machine), a box office ticket selling (supplementing) machine, an automatic value adding (inquiring) machine and the like, and is used for providing various ticket selling and checking services for passengers. The station terminal may be installed in an exhibition hall layer of each station of the urban rail transit system and connected to the station center computer system 130 through a station network. Station terminals in the AFC system can simultaneously support two working modes, namely networking and offline, and each station terminal comprises a main control unit, an input/output device, a Radio Frequency Identification (RFID) read-write component and the like.

Taking a station terminal as an automatic ticket checker as an example, ticket card reading and writing equipment is arranged in the station terminal, and when a passenger swipes a card on the station terminal to enter or swipes the card to exit, the ticket card reading and writing equipment can read data in the passenger ticket card; if the data in the passenger ticket card meets the requirement of the passenger for swiping the card at this time, the station terminal can allow the passenger to enter or exit; correspondingly, the ticket card reading and writing equipment can write data into the passenger ticket card according to the card swiping condition of the passenger. Further, the station terminal may generate card swiping information of the passenger according to data changes in the passenger ticket card, and report the card swiping information of the passenger to the station center computer system 130, the station center computer system 130 is configured to report the card swiping information of the passenger to the line center computer system 120, and the line center computer system 120 is configured to report the card swiping information of the passenger to the multi-line center computer system 110.

It can be known that the existing urban rail transit system mainly collects data of each station terminal based on the AFC system, the data collection needs to be packed step by step through the four-stage architecture and finally reported to the multi-line central computer system 110, and the step by step packing process generally has a delay of 5-15 minutes, so that the timeliness of data collection is poor. Moreover, the AFC system is fixed in the data collection mode of each station terminal, and the data collected by each station terminal is consistent and the collection process is also consistent, for example, the transaction data of each station terminal can be reported to the multi-line center computer system 110 step by step, and the operation data is only reported to the line center computer system 120 and is finished, and is not reported to the multi-line center computer system 110 any more, so that the multi-line center computer system 110 cannot know the fault condition and the operation state of each station terminal in time, and cannot perform centralized management on each station terminal. Therefore, the existing urban rail transit system also has the problem of inflexible data acquisition.

In order to solve the above problem, in a possible solution, the original architecture of the AFC system may be adjusted, for example, each station terminal is directly connected to the multi-line center computer system 110, and the multi-line center computer system 110 performs centralized management on each station terminal; or the cloud platform is arranged and is directly connected with each station terminal, and the cloud platform completes the function of AFC software. However, the above methods directly adjust the original architecture of the AFC system, the adjusted architecture not only needs to complete the AFC software function, but also supervises each station terminal based on the AFC software, the supervision function still depends on the AFC software, and if the AFC software has a problem, the supervision function is also unavailable accordingly. Moreover, the supervision function occupies more system resources, thereby affecting the operation capability of the AFC software. In addition, the cloud platform can operate only by depending on a network, so that the cloud platform is used for replacing an original AFC system, the station terminal can only support a networking working mode and cannot support an offline working mode, and the original transaction capability of the station terminal is influenced.

Based on this, the embodiment of the present invention provides a data processing method for a bypass urban rail transit system, so as to perform centralized supervision on each station terminal in an AFC system on the basis of not affecting the original function of the AFC system, thereby improving the flexibility and the real-time performance of supervising the station terminals.

Fig. 2 is a schematic structural diagram of a bypass urban rail transit system according to an embodiment of the present invention, and as shown in fig. 2, the bypass urban rail transit system further includes a central management device 150 in addition to the four-level structure of the AFC system. The central management device 150 may be connected to each station terminal 140 in the AFC system in a bypass manner, for example, by a wired connection, or may be connected by a wireless connection, which is not limited.

It should be noted that, the bypass connection according to the embodiment of the present invention refers to: AFC software and supervision software are deployed on each station terminal at the same time, the AFC software participates in the AFC function of the AFC system and is responsible for completing various transactions, and the supervision software participates in the centralized supervision function of the central management device 150 and is responsible for data acquisition and data reporting of the station terminal. In other words, the AFC software in the station terminal forms a main road with the station center computer system 130, the line center computer system 120, and the multi-line center computer system 110, the supervision software in the station terminal forms a bypass with the center management device 150, the main road is responsible for the original functions of the AFC system, the bypass is responsible for the data acquisition and supervision functions of the station terminal, and the bypass can also supervise the operation condition of the AFC software of the station terminal on the main road, but does not affect the operation of the main road.

Based on the bypass urban rail transit system illustrated in fig. 2, fig. 3 is an interaction flow diagram corresponding to a data processing method provided in the embodiment of the present invention, where the method includes:

step 301, the station terminal acquires data of the station terminal according to the acquisition task corresponding to the station terminal.

Here, the station terminal may be any station terminal in the AFC system.

In the embodiment of the present invention, the acquisition tasks corresponding to each station terminal may be configured directly by the operation and maintenance staff at the station terminal side, may also be distributed to each station terminal after being configured at the central management device side in advance by the operation and maintenance staff, and may also be acquired by each station terminal from a third-party device, which is not limited specifically.

In a possible implementation manner, the acquisition tasks corresponding to the station terminals may be configured on the side of the central management device, and the method specifically includes the following steps:

in step 3011, the central management apparatus provides an acquisition plan configuration interface to the user.

Step 3012, after detecting that the user inputs the collection plan configuration information on the collection plan configuration interface, the central management device obtains and analyzes the collection plan configuration information to obtain each collection plan.

Here, any acquisition plan may include an acquisition scope, an acquisition time, and an acquisition item, or may further include other information such as an acquisition plan name, an acquisition plan alias, an acquisition script parameter, a device type group, an operating system group, and the like, without limitation.

In the embodiment of the invention, the acquisition range can be defined by one or more items of the type of the operating system, the type of the station terminal, the attribution area and the identifier of the station terminal. The embodiment of the invention supports the user to freely combine the following types at the side of the central management equipment to obtain any acquisition range:

the type one is as follows: the general type is suitable for carrying out data acquisition on all station terminals in an AFC system;

type two: the type of the operating system is suitable for data acquisition of the station terminal with the operating system of the corresponding type, for example, if the type of the operating system is set to be a cutting version Linux operating system, data acquisition is performed on the station terminal with the cutting version Linux operating system deployed in all the station terminals of the AFC system;

type three: the type of the station terminal is suitable for data acquisition of the station terminal of the type, for example, if the type of the station terminal is set as a box office ticket machine, data acquisition is carried out on all box office ticket machines of the AFC system, and data acquisition is not carried out on an automatic ticket machine, an automatic ticket checker (gate), a box office ticket supplementing machine and an automatic value adding (inquiring) machine;

type four: the attribution area of the station terminal is suitable for data acquisition of all the station terminals included in the area, for example, if the attribution area is set as a station A, data acquisition of all the station terminals deployed in the station A is performed, or if the attribution area is set as a 16-number line, data acquisition of the station terminals deployed in each station through which the 16-number line passes is performed;

type five: the identification of the station terminal is suitable for data acquisition of the station terminal with the identification.

For example, if the acquisition range is defined by the type of the operating system "cut version Linux operating system" and the type of the home area "16 lines", the acquisition range corresponds to all station terminals of the cut version Linux operating system in all station terminals deployed on the 16 lines, and if the acquisition range is defined by the type of the operating system "cut version Linux operating system", the type of the home area "16 lines" and the type of the station terminal "automatic ticket gate", the acquisition range corresponds to all automatic ticket gates of the cut version Linux operating system in all station terminals deployed on the 16 lines.

As an example, the central management apparatus may further perform configuration management on each acquisition plan based on a database table to obtain an acquisition plan master table, so as to improve flexibility of acquisition plan management. The type of the database table may be an Oracle database table, an SQL database table, or a Mysql database table, and is not limited specifically.

Fig. 4 is a schematic diagram of an acquisition plan main table obtained based on Oracle database table configuration, as shown in fig. 4, the acquisition plan main table includes each acquisition plan, each acquisition plan occupies one row of the Oracle database table, and one or more items of an acquisition plan name, an acquisition plan alias (for defining an acquisition item), an acquisition period (i.e., acquisition time), an acquisition script parameter, an equipment type group, an operating system group, a line group, a site group, and an equipment group may be stored in a row corresponding to each acquisition plan. For example, referring to the third row of the collection plan master table, the collection plan corresponding to the third row is used to collect performance data of all station terminals with the cutting edition linux operating system, and referring to the fourth row of the collection plan master table, the collection plan corresponding to the fourth row is used to collect hard disk data of all station terminals on the line 15 and the line 14.

In one example, the central management device may further support the user to create a new acquisition plan, remove an existing acquisition plan, modify an existing acquisition plan, or query an existing acquisition plan, and after detecting that an acquisition plan is updated, the central management device may further automatically distribute the updated acquisition plan to each corresponding station terminal, so as to improve the accuracy of data acquisition. Taking the example of clearing the existing acquisition plan, when it is detected that the user triggers the modification instruction in the acquisition plan configuration interface, the central management device may display the acquisition plan master table to the user, so that the user may directly select the acquisition plan to be cleared on the acquisition plan master table to perform deletion operation, or may set the acquisition plan to be cleared to a failure state without limitation.

In the above example, the user sets each acquisition plan on the acquisition plan configuration page of the central management device, so that the acquisition plans and the services can be decoupled, the user is supported to configure different acquisition tasks for different station terminals according to respective service requirements, and the flexibility of data acquisition is improved; and each acquisition plan is configured through a configuration interface, so that the operation can be simplified, the cost and the event of manual operation and maintenance are reduced, and the data acquisition efficiency is improved.

And 3013, the central management device extracts the acquisition plans belonging to the same station terminal from the acquisition plans according to the acquisition ranges corresponding to the acquisition plans, and aggregates the acquisition plans belonging to the same station terminal to obtain the acquisition tasks corresponding to the station terminal.

In the embodiment of the present invention, because the alias of the collection plan is used to define the collection item, the central management device may further store a collection item itemization table, where the collection item itemization table is used to store the relevant configuration information of each collection item corresponding to any alias of the collection plan, and specifically may include a rule name, a rule alias, a processing service code, a monitoring item (i.e., a collection item), a rule expression, and the like of the collection item.

In a specific implementation, for any acquisition plan configured by the user, the central management device may first obtain an acquisition plan alias corresponding to the acquisition plan by querying the acquisition plan main table, then query the acquisition item itemizing table corresponding to the acquisition plan alias, and determine each acquisition item corresponding to the acquisition plan. For example, the acquisition plan corresponding to the fifth row of the acquisition plan main table in fig. 4 is used to acquire Solaris performance data, and the acquisition item sub-table corresponding to the Solaris performance data is shown in fig. 5, it can be known that the acquisition items corresponding to the Solaris performance data may include Solaris CPU occupancy, Solaris memory remaining space, Solaris memory total space, Solaris swap remaining space, and Solaris swap total space, and each acquisition item corresponds to its own rule, code, and acquisition method. Thus, the acquisition plan corresponding to the fifth row of the acquisition plan master table in fig. 4 is actually used for data acquisition of each acquisition item included in the Solaris performance data.

Further, the central management device may generate the collection task corresponding to each station terminal in a plurality of ways, such as:

in one example, for any station terminal, the central management device may determine each acquisition plan applicable to the station terminal according to an area to which the station terminal belongs, a route to which the station terminal belongs, and an operating system deployed on the station terminal, and then generate an acquisition task corresponding to the station terminal according to an acquisition item and acquisition time in each acquisition plan applicable to the station terminal.

Alternatively, the first and second electrodes may be,

in another example, the central management device may sequentially traverse each acquisition plan, and when traversing each acquisition plan, for any station terminal in the acquisition plan, if an acquisition task table corresponding to the station terminal already exists, add an acquisition item and acquisition time corresponding to the station terminal in the acquisition plan to the acquisition task table corresponding to the station terminal. And if the acquisition task table corresponding to the station terminal does not exist, establishing the acquisition task table corresponding to the station terminal, and adding the acquisition item and the acquisition time corresponding to the station terminal in the acquisition plan into the acquisition task table corresponding to the station terminal. Therefore, after traversing all the acquisition plans, the central management device can obtain the acquisition task list corresponding to each station terminal.

Correspondingly, before step 301, the station terminal may further obtain a collection task corresponding to the station terminal from the central management device by the following steps:

in step 3021, the station terminal transmits a registration request to the center management apparatus.

Step 3022, the central management apparatus performs validity verification on the registration request of the station terminal, and if the verification is successful, establishes communication connection with the station terminal.

Here, the communication connection is used to allow the station terminal to acquire an acquisition task corresponding to the station terminal. After the communication connection is established, the central management apparatus may further transmit a response message that the registration is successful to the station terminal.

Accordingly, if the authentication fails, the central management apparatus may refuse to establish a communication connection with the station terminal and transmit a response message of the registration failure to the station terminal.

And step 3023, the station terminal obtains a collection task corresponding to the station terminal from the central management device.

In specific implementation, if the station terminal receives the response message of successful registration, the station terminal may obtain the acquisition task corresponding to the station terminal from the central management device, and store the acquisition task corresponding to the station terminal in the local database. If the station terminal does not receive the response message or receives the response message of registration failure, the station terminal can periodically and repeatedly send the registration request to the central management device, and if the registration is not successful after the repeated sending of the set times, the station terminal gives up the registration and generates the alarm message.

In the embodiment of the present invention, the station terminal may obtain the collection task in a variety of ways, for example, after receiving the response message of successful registration, the station terminal may send a collection task obtaining request to the central management device, after the central management device verifies that the sender of the collection task obtaining request is the pre-registered station terminal, the collection task corresponding to the station terminal is sent to the station terminal, or after the central management device successfully establishes a communication connection with the station terminal, the collection task corresponding to the station terminal is actively sent to the station terminal, which is not limited specifically.

In order to ensure the consistency of the acquisition tasks between a configuration party (namely, a central management device) and an execution party (namely, a station terminal) and improve the accuracy of data acquisition, the station terminal can periodically acquire the corresponding acquisition tasks from the central management device, or the central management device can monitor a local database in real time, once the acquisition plan is detected to be updated by a user, an update instruction can be issued to the station terminal corresponding to the updated acquisition plan, and the updated acquisition tasks are carried in the update instruction, so that the station terminal can acquire the updated acquisition tasks in real time.

In the implementation mode, the central management device manages the acquisition plans in a unified way, and each station terminal acquires the corresponding acquisition task from the central management device, so that the acquisition plans can be configured on the side of the central management device in a centralized way without being configured in each station terminal separately, and the flexibility and the convenience of the configuration of the acquisition plans can be improved; and the station terminals are used as units to divide the acquisition tasks of the acquisition plan, so that the data acquisition process is more targeted, the requirements of actual acquisition scenes of different station terminals are met, and flexible supervision of each station terminal is realized.

In a possible implementation manner, the station terminal encapsulates the acquisition method corresponding to each acquisition item, and the acquisition method corresponding to each acquisition item is matched with the operating system of the station terminal, the operating system of the station terminal may be an embedded operating system or any type of cutting version operating system, and the cutting version operating system may be a cutting version of various commercial release version operating systems, such as a cutting version Unix system, a cutting version Linux system, a cutting version Windows system, and the like, without limitation. Therefore, after the station terminal acquires the corresponding acquisition task, for any acquisition item in the acquisition task, the target acquisition method can be determined according to the acquisition item and the operating system of the station terminal, and then the data corresponding to the acquisition item is acquired by using the target acquisition method during the acquisition time corresponding to the acquisition item.

The method for acquiring the encapsulation in the station terminal mainly comprises the following steps:

the acquisition method comprises the following steps: extracting the result content output by the self-contained command by combining the self-contained command and the regular expression of the operating system in the station terminal so as to monitor and collect data of the running state (such as the memory utilization rate of a CPU) of the station terminal;

the second acquisition method comprises the following steps: reading a designated file in a station terminal, and extracting contents corresponding to acquisition items from the designated file through a regular expression so as to perform data monitoring and data acquisition operations on partial transaction data;

the acquisition method comprises the following steps: monitoring a designated file in a station terminal, and acquiring the changed content once the content of the designated file is changed so as to perform data monitoring and data acquisition operation on the changed transaction data;

the acquisition method comprises the following steps: monitoring an appointed directory in a station terminal, and acquiring newly added file contents once newly added files under the appointed directory are found so as to perform data monitoring and data acquisition operations on newly added transaction data;

the acquisition method comprises the following steps: executing a configuration script of AFC software, and extracting specific content from the execution script through a regular expression so as to perform data monitoring and data acquisition operations on software information of an AFC system, parameter version information of the AFC system and software running state of the AFC system;

the acquisition method comprises the following steps: and executing a configuration script of monitoring software in the station terminal, and extracting specific content through a regular expression so as to perform data monitoring and data acquisition operation on the running state of the station terminal.

Based on the above content, in the embodiment of the invention, the station terminal can not only collect the operation state and the transaction data to the central management device, but also collect the software information, the parameter version information and the software operation state related to the AFC system, so that the central management device can collect more comprehensive data, improve the supervision effect, and timely acquire the operation condition of the AFC software and repair the fault; in addition, the central management device of the scheme is connected with the station terminal through the bypass, so that the station terminal can continue to report data even if AFC software fails, and the availability of the supervision function is good.

It should be noted that the acquisition method in the station terminal is developed based on the standard C language, and has the characteristics of small program code amount, high running speed and strong hardware interaction function. In addition, the embodiment of the invention also configures a Socket Tcp communication module, a zip processing module and an ftp file transmission module which are depended when the acquisition method is executed in the station terminal, and the modules have universality and are suitable for a cutting version operating system of each station terminal in an AFC system. In addition, the data collected in the station terminal are stored based on the tree-shaped custom storage structure of the pointer, so that resources required by data storage are reduced, and the efficiency of data reporting is improved.

In the embodiment of the invention, each station terminal is provided with the acquisition method matched with the local cutting version operating system, and the acquisition method is customized and developed for the station terminal of the AFC system, so that compared with the general monitoring system in the prior art, the problem that part of functions in the general monitoring system cannot be realized is solved, a large number of unnecessary system functions can be saved, the occupation amount of the acquisition method on resources in the station terminal is reduced, and the influence on the AFC software function in the station terminal is reduced; in addition, the acquisition methods corresponding to various acquisition items are packaged in the station terminal in advance, so that the station terminal can directly call the existing acquisition methods to execute acquisition operation, and the data acquisition efficiency can be improved.

Step 302, the station terminal reports the data of the station terminal to the central management device.

In a possible implementation manner, before reporting data, the station terminal may further encapsulate the data based on the type of the data to obtain a request message of a corresponding type, where the encapsulation manner mainly includes the following steps:

packaging mode 1: data are packaged in a key value pair mode, the key value pair mode is that the name of an acquisition item is the parameter value of the acquisition item, one or more key value pairs can be contained in a packaged request message, and the number of the key value pairs is related to the acquisition items corresponding to the station terminal;

packaging mode 2: converting the collected data into a binary format and reporting the binary format, wherein the binary format is suitable for reporting transaction data;

packaging mode 3: the JSON format is adopted to convert data, and the method is suitable for reporting data with fixed attributes, such as the software version and the parameter version of AFC software.

In the implementation mode, the data is encapsulated by using the encapsulation mode corresponding to the type of the data, so that the reported request message can better meet the requirement of the data type, and the efficiency of data analysis of the central management equipment is improved while the occupied space is saved.

In the embodiment of the invention, in order to reduce communication consumption, a Socket synchronous short connection mode can be adopted for communication between the station terminal and the central management device. During communication, messages are all initiated at the station terminal side and are responded by the central management device, and the messages are presented in pairs in a question-and-answer mode. Once the station terminal receives the response of the central management device, the station terminal can actively disconnect the communication connection with the central management device so as to reduce the resource occupation of the central management device.

In a specific implementation, the communication protocol of the station terminal and the central management device can be set based on a TCP/IP protocol. The communication message is a proprietary protocol message in a self-defined text format, and the message can be assembled according to the form of a message header, a message body (data acquisition content) + a check bit, for example, a request message sent by a station terminal is set according to the data field format of a fixed-length message header, a signature and a variable-length message body, and a response message sent by the central management device is set according to the data field format of the fixed-length message header and the variable-length message body.

For example, table 1 is a schematic diagram of a format of a request packet provided in the embodiment of the present invention:

TABLE 1

Table 2 is a schematic diagram of a format of a response packet provided in the embodiment of the present invention:

TABLE 2

And step 303, the central management device performs centralized management on the station terminals according to the data of the station terminals.

In a possible implementation manner, a message queue corresponding to each data type may be further provided in the central management device, and data in each message queue is processed in an asynchronous manner. For example, if the communication protocols between the station terminal and the central management device may include a registration protocol 100100, an acquisition plan protocol 100300, a data reporting protocol (including a full-volume status data protocol 100400 and a transaction data protocol 200100), a data updating protocol (including variable status data 100600) and a heartbeat protocol 100500, the central management device may correspondingly set a corresponding 100100 registration message queue, a 100300 acquisition plan message queue, a 100400 device full-volume status data message queue, an 100500 heartbeat data message queue, a 100600 variable status data message queue and a 200100 transaction data message queue according to the type of the communication protocol.

In specific implementation, the station terminal may encapsulate the request message according to the type of the data, and may also carry the type of the data (or a corresponding communication protocol) in the request message, where the type of the data may be one or more of registration request data, full state data, variable state data, transaction data, and heartbeat data. Correspondingly, after receiving the request message, the central management device may further add the data to the message queue corresponding to the type of the data according to the type of the data carried in the request message.

It should be noted that the type of each message queue in the central management device may be an MQ message queue, such as an ActiveMQ message queue, a RabbitMQ message queue, and the like, and is not particularly limited.

In the implementation mode, the station terminal carries the type of the data in the request message, so that the central management device can directly place the request message in the corresponding message queue according to the type of the data without performing the operation of analyzing the data to determine the type of the data, thereby improving the processing efficiency of the data; and, through set up a plurality of message queues processed in parallel at the side of central management apparatus, and use each message queue to store the data of a kind of data type, can further raise the efficiency of data processing.

In the embodiment of the invention, the station terminal can be divided into three modules in terms of software function: an Agent module, an AgentWatcher module and an AgentKill module. The Agent module is configured to implement the data acquisition and reporting operations described in the above embodiments of the present invention, such as acquiring and reporting the operating state data of each station terminal, the version and/or parameter version of AFC software, acquiring and reporting the data transmission and communication states of each level of architecture in the AFC system, and acquiring and reporting the transaction data of the station terminal. The AgentWatcher module is used for monitoring the running state of the agent module, and once the running abnormality of the agent module is found, the agent module can be restarted. The AgentKill module is used for stopping the related processes when the Agent module executes data acquisition and reporting operations, and ensuring the safe exit of the related processes by sending exit instructions to the related processes.
