Firstly, in the intelligent and internet-of-things construction of the rail transit subway station, the design of each physical terminal of the station needs to be linked, information communicated and behavior processed. Typical physical terminal equipment of subway stations is: rolling door, water valve, energy-saving equipment, escalator, NCC equipment, camera and environmental sensor. The number of the terminal physical devices in the subway station is more, the station is more, and the cost for constructing the real all-terminal devices of the all-network all-station hall of a certain subway operator is high. The interaction of the services of different types of terminal devices in the different order of magnitude rail traffic scenarios is quite complex.
In order to reduce or even avoid factors such as artificial operation failure in rail traffic accidents in a rail traffic scene, certain operation training is needed before subway dispatchers go on duty to simulate various accidents and provide the dispatcher with processing capability, so that the capability of processing the accidents is improved, and the occurrence of the rail traffic accidents is reduced to a certain extent. At present, in order to simulate the scenes of various accidents, very complex running scripts are required to be written, and a large amount of data close to reality is prepared. This makes the simulation process very labor and material intensive, and the number of scripts that can be provided is very limited.
Fig. 1 is a schematic diagram of an implementation environment of a terminal device simulation in an on-track scenario according to an exemplary embodiment of the present application. As shown in fig. 1, a terminal device is constructed on a simulation platform 110, a product name of the terminal device is added, a corresponding protocol type is selected, an attribute and a data type of the terminal device are filled in according to an object model of the terminal device, then the terminal device model is packaged into a corresponding terminal device model, the terminal device model is marked, the marked terminal device is obtained, a corresponding service link is generated according to service information of the terminal device, and then the service link is sent to an internet of things platform 120, so that the operation condition of the terminal device in an rail transit scene is simulated based on the internet of things platform, and the simulation of a certain rail transit scene is realized.
The simulation platform 110 shown in fig. 1 may be any terminal device supporting programming, such as a smart phone, a tablet computer, a notebook computer, or a wearable device, but is not limited thereto. The internet of things platform 120 shown in fig. 1 may be a simulation platform constructed based on an industrial internet of things standard protocol (HTTP/Modbus/TCP/MQTT), so as to simulate different types of terminals in the scale number level of the hall, realize the internet of things communication between the simulation terminals and the service system, complete the equipment state simulation, the function simulation, the event simulation and the behavior simulation, and satisfy the service system debugging and verification. The simulation platform 110 may communicate with the internet of things platform 120 through a wireless network such as 3G (third generation mobile information technology), 4G (fourth generation mobile information technology), 5G (fifth generation mobile information technology), and the like, which is not limited herein.
The problems noted above have general applicability in general rail traffic scenarios, and it can be seen that the amount of data involved is enormous and costly to perform analogue tests for interactions and communications between the various physical terminals in different rail traffic scenarios. In order to solve these problems, embodiments of the present application respectively propose a terminal device simulation method in a track crossing scene, a terminal device simulation apparatus in a track crossing scene, an electronic device, a computer-readable storage medium, and a computer program product, and these embodiments will be described in detail below.
Referring to fig. 2, fig. 2 is a flowchart illustrating a terminal device simulation method in a track crossing scenario according to an exemplary embodiment of the present application. The method may be applied to the implementation environment shown in fig. 1 and executed by the simulation platform 110 in the implementation environment, and it should be understood that the method may also be applied to other exemplary implementation environments and executed by devices in other implementation environments, and the implementation environment to which the method is applied is not limited by the embodiment.
As shown in fig. 2, in an exemplary embodiment, the terminal device simulation method in the track traffic scenario at least includes steps S210 to S240, which are described in detail as follows:
step S210, a configuration file for simulating the terminal equipment model is obtained, and the terminal equipment model is generated based on the configuration file.
Specifically, typical physical terminal devices at a common subway station are: rolling door, water valve, energy-saving equipment, escalator, NCC equipment, camera and environmental sensor. In this embodiment, script files of each physical terminal device may be configured on the simulation platform, for example: script files of equipment such as a roller shutter door, a water valve, an escalator and the like in a map station, and a terminal equipment model is generated based on the configured script files.
By way of example, the physical terminal device in the rail traffic scene is configured on a simulation platform, for example: and inputting the name of the required simulated terminal equipment, the protocol type supported by the equipment, the IP address of the terminal equipment and the attribute of the Internet of things model of the equipment, wherein the attribute of the Internet of things comprises the attribute of the equipment, the characteristics on the Internet of things level and the like, and generating a corresponding terminal equipment model according to the configuration file.
Step S220, configuring a plurality of state parameters in the terminal device model to generate corresponding terminal devices based on the plurality of state parameters.
Specifically, since the roles of different kinds of terminal devices are different, the properties to be detected by the model of the terminal device are also different, for example, an escalator, and operation data, fault properties and the like of the escalator need to be monitored. Therefore, in this embodiment, after the terminal device is generated, some attributes on the terminal device model need to be marked according to the attributes of the terminal device, so that when the simulation operation is performed under the platform of the internet of things, the data of the marked attributes can be monitored in real time, so as to obtain the operation condition of the terminal device in the current rail traffic state in real time.
Further, in some possible embodiments, the most intuitive information such as the IP, the communication port, the online status, etc. of the packaged terminal device may be displayed on the analog platform, and the online and offline operations and the command editing operations may also be performed on each device.
Step S230, a session interface between the terminal equipment and the platform of the Internet of things is obtained, so that a session link of the terminal equipment is generated according to the session interface.
Specifically, session information between the terminal equipment and the internet of things platform is obtained, wherein the session information comprises a session port of the terminal equipment, and session linking is realized according to a standard internet of things communication protocol so as to realize communication between the terminal equipment and the internet of things platform.
The construction process of the session link further comprises the following steps: session creation, connection management, data interaction, and maintenance of terminal status.
Further, in some implementable embodiments, one session port may be acquired from the internet of things platform to establish a session link of the terminal device with the internet of things platform based on the session port.
Specifically, the service information is also referred to as data interaction information of the terminal device, that is, data interaction information between a plurality of terminal devices in a subway station in different scenes, where the scenes of data interaction include: data interactions between devices, functional interactions between devices, tool interactions between devices, and the like.
Further, after obtaining the service information of the terminal device, establishing a service link applicable to the internet of things platform according to the service information of the terminal device, where the method includes: according to the standard internet of things communication protocol, communication between the simulation equipment and the internet of things platform is achieved, namely a session port between the simulation platform and the internet of things platform is selected, a session link of the terminal equipment is generated based on the session port, and the session link is used for sending data of the terminal equipment to the internet of things platform and receiving data returned by the internet of things platform.
Step S240, the session link is sent to the Internet of things platform, so that the running condition of the terminal equipment in the track traffic scene is simulated based on the Internet of things platform.
Specifically, the service link of the marked terminal equipment is sent to the internet of things platform, and the marked terminal equipment is decoded according to the attribute of the terminal equipment to obtain a corresponding Modbus instruction. The operation condition of the terminal equipment in the rail traffic scene is simulated by the Internet of things platform under the Modbus instruction.
It should be noted that the Modbus protocol is a general language applied to the electronic controller. Through this protocol, the controllers can communicate with each other, with the controllers via a network (e.g., ethernet) and other devices. It has become a common industry standard. With the control device, control devices produced by different manufacturers can be connected into an industrial network to perform centralized monitoring. This protocol defines a message structure that a controller can recognize for use, regardless of the network over which they communicate. It describes the process of one controller requesting access to other devices, how to respond to requests from other devices, and how to detect errors and record. It formulates a common format for message domain schemas and content. When communicating over a Modbus network, this protocol determines what actions each controller needs to know their device address, identify messages sent by address, and determine what actions to take. If a response is required, the controller will generate feedback information and issue using the Modbus protocol. On other networks, messages containing the Modbus protocol are converted into a frame or packet structure for use on the network. This translation also extends the methods of resolving node addresses, routing paths, and error detection according to the particular network.
Furthermore, in some implementable embodiments, the end device that created the success is stored in a designated database to facilitate the next call and operation.
In the embodiment, the method and the device for generating the terminal equipment model based on the configuration file for simulating the terminal equipment on the simulation platform, and marking the terminal equipment based on the attribute of the terminal equipment to obtain the marked terminal equipment, so that the marked attribute is monitored in the running process, and the running load of the platform of the Internet of things is reduced. And then, establishing a corresponding service link according to the service information of the terminal equipment, so that the running condition of the terminal equipment can be simulated on the Internet of things platform according to the service connection, the design and connection of the terminal equipment in the rail traffic scene are simplified, and the simulation cost is reduced.
Further, based on the foregoing embodiment, in one exemplary embodiment provided by the present application, the configuration file includes an internet of things attribute of the terminal device; the specific implementation process of configuring a plurality of state parameters in the terminal device model to generate the corresponding terminal device may further include the following steps, which are described in detail below:
based on the internet of things attribute of the terminal device, configuring a plurality of state parameters in the terminal device model to generate corresponding terminal devices based on the plurality of state parameters.
Specifically, the terminal equipment model is marked based on the internet of things attribute of the terminal equipment model, then the marked terminal equipment model is obtained,
referring to fig. 3, in fig. 3, if the terminal device simulated on the simulation platform is a rolling door, the device model of the rolling door is marked, as shown in fig. 3, a product "rolling door" is selected, the device number is "JLM-0200", the IP is "10.10.7.31", the port is "9050", and then the state of the rolling door is assigned, that is, the marking process is performed, based on the internet of things characteristic of the rolling door, for example, the state-1"0", the action state-1"0", the fault state-1"0", the state-2"0", the action state-2"0", the fault state-2"0", whether there is a person-1"0", and whether there is a person-2"0", that is, the marking process of the terminal device is completed through the assignment.
In addition, the terminal equipment model under the attribute of the internet of things needs to follow the attribute of the internet of things of the terminal equipment, namely the attribute of the internet of things of the terminal equipment cannot be exceeded.
In this embodiment, the marking process is performed on the terminal device point according to the attribute of the internet of things of the terminal device, where the marking process aims at assigning a value to the terminal device model to establish a state model of the terminal device, so as to obtain the state of the terminal device in the track crossing scene.
Further, based on the above embodiment, referring to fig. 4, in one exemplary embodiment provided by the present application, the specific implementation process of acquiring the service information of the terminal device to establish the service link of the marked terminal device based on the service information may further include the following steps S410 to S420, which are described in detail below:
step S410, obtaining the behavior simulation parameters of the terminal equipment stored in the specified database.
Step S420, a behavior state of the terminal equipment is built based on the behavior simulation parameters.
In some possible embodiments, a database storing a plurality of terminal device models in the rail traffic scene is built in advance, and a behavior simulation model of the plurality of terminal devices is stored in the model database. And obtaining behavior simulation data of the terminal equipment from the appointed database according to the identification information such as the equipment number of the terminal equipment, thereby obtaining the behavior state of the terminal equipment according to the behavior simulation model of the terminal equipment, for example: the terminal device is a rolling door, and the corresponding behavior state can be obtained according to the behavior simulation model of the terminal device, wherein the behavior state is as follows: state-1"0", action state-1"0", fault state-1"0", state-2"0", action state-2"0", fault state-2"0".

Referring to fig. 5, fig. 5 is a schematic flow chart of terminal equipment configuration in an exemplary rail traffic scenario according to the present application. Acquiring a configuration file of the terminal equipment to be simulated from a database of a preset track crossing scene on a simulation platform of the terminal equipment, inquiring attribute values (string) and attribute types (int, float and the like) of the equipment according to the configuration file, and then packaging the terminal equipment by the data types of the terminal equipment to obtain the packaged terminal equipment. And then, a session interface between the current terminal equipment and the Internet of things platform is obtained, the terminal equipment is processed through the session to obtain a corresponding session link, wherein the session link can be in a HttpMessage, mqttMessag format, and the packaged terminal equipment is sent to the Internet of things platform through the session link so as to simulate the running condition of the terminal equipment in an on-track traffic scene on the Internet of things platform.
Further, based on the above embodiment, referring to fig. 6, in one exemplary embodiment of the present application, a specific implementation process of the terminal simulation method in the track traffic scenario may further include the following steps S610 to S630, which are described in detail below:
step S610, monitor the change strategy of the terminal device.
In particular, in some embodiments, the relevant administrator may change the properties of the terminal device on the simulation platform according to the actual scenario requirements. In an actual subway station, the people flow in different time periods is different, for example, 7:00-9:30 in the morning belongs to people flow peaks, and passengers at the roller shutter door are more than other time periods, and passengers on the escalator are more than other time periods, so that state parameters of the terminal equipment need to be changed.
The change policy for the terminal device may be manually modified by the relevant manager to modify the respective state parameters of the terminal device, and combined into the corresponding change policy for the terminal device. The corresponding system or the server can also automatically generate a change strategy corresponding to the terminal equipment according to the change of the time parameter.
In some exemplary embodiments, to further improve accuracy of the state of the terminal device obtained by simulation, a more comprehensive and strong opening needs to be considered in the simulation process of the behavior state of the terminal device, for example: the traffic, holidays, weather factors, etc. of different time periods can thus be used to simulate the state of the terminal device by means of machine learning.
Machine Learning (ML) is a multi-domain interdisciplinary, involving multiple disciplines such as probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory, etc. It is specially studied how a computer simulates or implements learning behavior of a human to acquire new knowledge or skills, and reorganizes existing knowledge structures to continuously improve own performance. Among them, machine learning is the core of artificial intelligence, which is the fundamental approach for making computers intelligent, and is applied throughout various fields of artificial intelligence. Machine learning and deep learning typically include techniques such as artificial neural networks, belief networks, reinforcement learning, transfer learning, induction learning, teaching learning, and the like.
Based on the strong learning capacity of machine learning, the machine learning process aiming at a large number of historical tracks can be used for realizing that the machine learning model estimates the states of the terminal equipment according to all-round characteristics such as the people flow, holidays, weather factors and the like of each terminal equipment in different time periods under the current rail traffic scene, so as to ensure that the estimated state parameters of the terminal equipment are more accurate and reliable. For example, the machine learning model may include a neural network-based supervisory model, such as a two-class machine learning model, which is trained by using a large number of historical trajectories, such that the machine learning model performs model parameter adjustment during the training process, such that the adjusted model parameters have a comprehensive predictive performance for the state of the terminal device.
Step S620, analyzing the change strategy to obtain the latest state parameters of the terminal equipment.
Specifically, the monitored change strategy of the terminal equipment is analyzed to obtain the latest state parameters of the terminal equipment. Taking a terminal device as a roller shutter door as an example, monitoring a change strategy aiming at the roller shutter door terminal device, and changing the state parameters of the roller shutter door by knowledge: state-1"0", action state-1"1", fault state-1"2", state-2"1", action state-2"0", fault state-2"1".
Step S630, generating a corresponding update package based on the latest state parameter, so as to update the terminal device based on the update package.
As described above, based on the change policy manually input by the related manager or automatically generated by the system, the latest state parameter of the terminal device may be determined by analyzing the change policy, and the latest state parameter of the terminal device in the change policy is encapsulated into a corresponding terminal device update package, so as to issue the update package of the terminal device to the corresponding simulation platform, so as to update the terminal device based on the update package, and obtain the terminal device corresponding to the change policy.
In some possible embodiments, considering that when the relevant manager manually inputs the state parameter in the change policy of the terminal device, the state parameter may be the same as the state parameter of the current terminal device, so that the latest state parameter of the terminal device in the update package may be the same as the current state parameter of the terminal device, when updating the terminal device based on the update package, it is generally the case that whether the latest state parameter in the update package is the same as the current state parameter of the terminal device is judged, and if the latest state parameter in the update package is the same as the current state parameter of the terminal device, updating of the state parameter is skipped.
In the embodiment, on one hand, the state parameters of the packaged terminal equipment are modified in a strategy changing mode, so that secondary processing of a terminal equipment model is realized, the process of re-firmware the terminal equipment after scene change is avoided, and the simulation cost is reduced; on the other hand, along with the change of the actual scene of the rail transit, the state parameters in the terminal equipment are updated, and the authenticity of the simulation process of the terminal equipment is further improved.
Further, based on the above embodiment, referring to fig. 7, in one exemplary embodiment of the present application, the specific implementation process of generating the corresponding update package based on the latest state parameter may further include the following step S710 and step S720, which are described in detail below:
step S710, judging whether the latest state parameter meets the requirement of the terminal equipment Internet of things attribute.
As described above, the latest state parameter for the terminal device, which is used for performing the state simulation on the terminal device, can be obtained after analyzing the change policy of the terminal device. In general, it is required to determine whether the latest state parameter meets the attribute requirement of the internet of things of the terminal device. Taking the example that the terminal equipment is a rolling shutter door, if the latest state parameter of the fault state-2 is '2' obtained by analyzing the corresponding change strategy, and based on the internet of things attribute of the rolling shutter door, if the fault state-2 which does not exist in the internet of things model of the rolling shutter door is the state parameter of '2', the state parameter of the fault state-2 in the change strategy of the terminal equipment is determined to be invalid. Similarly, if the state parameter of the fault state-2 existing in the internet of things model of the roller shutter door is "2", the state parameter of the fault state-2 in the change policy of the terminal device is determined to be valid.
Step S720, if the latest state parameter meets the requirement of the terminal equipment internet of things attribute, generating an update package of the terminal equipment based on the latest state parameter and the data attribute type.
As described above, if the latest state parameter in the change policy of the terminal device meets the requirement of the attribute of the internet of things of the terminal device, an update package of the terminal device may be generated according to the latest state parameter in the change policy of the terminal device, so as to change the state parameter of the terminal device according to the update package, and obtain the terminal device after attribute change with a message that attribute change has been completed on the simulation platform.
In the embodiment, when the latest state parameter in the change strategy of the terminal equipment meets the attribute requirement of the Internet of things of the terminal equipment, the update package of the terminal equipment is generated based on the latest state parameter and the data attribute type of the terminal equipment, so that the condition that the state of the terminal equipment is modified to be not in accordance with the attribute of the Internet of things of the terminal equipment is avoided, and the reality of the terminal equipment simulation is effectively provided.
Referring to fig. 8, fig. 8 is a schematic flow chart of updating a terminal device in an exemplary application scenario of the present application. In the application scenario shown in fig. 8, the relevant administrator or the corresponding system uploads the corresponding terminal device change policy, where the terminal device change policy may be manually input by the relevant technician, or may be a terminal device change policy generated in real time through the relevant machine learning model. When the simulation platform monitors the terminal change strategy, starting an automatic update program of the terminal equipment, analyzing the monitored terminal change strategy to obtain an analyzed latest state value of the terminal equipment, then checking whether the latest state value of the terminal equipment meets the requirement of the internet of things attribute of the terminal equipment, if the latest state value meets the requirement of the internet of things attribute of the terminal equipment, updating the terminal equipment based on the latest state value, after the terminal equipment is updated, uploading the corresponding updated terminal equipment to a corresponding database for storage, and issuing a terminal equipment change event message on the simulation platform. And then continuing to monitor the change information reported by the manager side, and returning the attribute change result of the terminal equipment to the manager side.
In the embodiment, the terminal equipment is updated by monitoring the change strategy of the terminal equipment and changing the state data in the strategy, so that the control of the simulation data and the secondary operation of the terminal equipment are realized, and the simulation cost is saved.
Further, based on the above embodiment, in one exemplary embodiment provided by the present application, the configuration file includes a device name, a protocol type, a data attribute type, and a data attribute value of the device, and the specific implementation process of generating the terminal device model based on the configuration file may further include the following steps, which are described in detail below:
the configuration file is encapsulated based on the protocol type, the data attribute type, and the data attribute value to generate a terminal device model named device name.
In this embodiment, the configuration file of the terminal device model includes an attribute model attribute of the internet of things of the terminal device, where the attribute includes different data types int and float. And according to the different merging in the method, each attribute is assigned so as to generate a corresponding instruction applicable to the Internet of things platform according to the attribute assignment after the upper limit of the equipment.
In some possible embodiments, the configuration file of the terminal equipment model is further used for creating equipment, configuring equipment parameters and defining equipment models, for example, when creating a fire water valve, configuring parameters of the fire water valve, determining the equipment model of the fire water valve to obtain a fire water valve model, obtaining a fire water valve model which can be called at any time, and in addition, the configuration file of the terminal equipment comprises an IP value of the terminal equipment model, when the terminal equipment is packaged, the method comprises the following steps: the method comprises the steps of inputting a product name, selecting a protocol type, filling in an attribute according to an object model, increasing and decreasing attribute support, dividing the attribute into field names, describing, and data types, decoding different data types differently, and obtaining a corresponding terminal equipment model so as to facilitate subsequent calling or secondary editing.
In this embodiment, the data of different types of terminal devices are automatically constructed by encapsulating the configuration file of the terminal device to be simulated, and the communication and service interaction between the simulation device and the service system are directly performed.
Further, based on the above embodiment, as shown in fig. 9, in one exemplary embodiment provided by the present application, the specific implementation process of sending the session link to the platform of the internet of things to simulate the operation condition of the terminal device in the track traffic scene based on the platform of the internet of things may further include the following step S910 and step S920, which are described in detail below:
step S910, performing decoding processing on the data attribute value of the terminal device, so as to generate a corresponding Modbus instruction based on the decoded attribute value;
step S920, the operation condition of the terminal equipment in the rail traffic scene is simulated on the basis of the Modbus instruction by the Internet of things platform.
Specifically, the decoding process may be performed on the attribute value in the configuration file for generating the terminal device model, where the data types of the terminal devices are different, and the decoding modes adopted by the data types are different, so that the corresponding Modbus instruction is generated based on the attribute value of the terminal device, so that the device address of the terminal device and the function code (state parameter, etc.) of the terminal device are obtained through the knowledge of the Modbus instruction. For example: the function code in the query message tells the selected slave device what function to perform. The data segment contains any additional information that the slave device is to perform. For example, the function code 03 requires reading the holding registers from the device and returning their contents. The data segment must contain information to inform the slave: from which register to start reading and the number of registers to read. If a normal response is generated from the terminal device, the function code in the response message is the response of the function code in the inquiry message. The data segment includes data collected from the device: such as a register value or state. If an error occurs, the function code is modified to indicate that the response message is erroneous, and the data segment contains code describing the error information. The error detection field allows the master to confirm whether the message content is available. Therefore, the operation condition of the terminal equipment in the rail traffic scene is simulated on the Internet of things platform based on the Modbus instruction.
In the embodiment, the data attribute value of the terminal equipment is decoded to generate the corresponding instruction according to the attribute of the terminal equipment, so that the running condition of the terminal equipment in the rail traffic scene is simulated under the internet of things platform, the running condition of the terminal equipment can be simulated on the internet of things platform according to the service connection, the design and connection of each terminal equipment in the rail traffic scene are simplified, and the simulation cost is reduced.

The method comprises the steps of obtaining a configuration file of the terminal equipment to be simulated from a preset database of a track crossing scene on a simulation platform of the terminal equipment, inquiring attribute values (string), IP values, state names, attribute types (int, float and the like) of the equipment according to the configuration file, and then packaging the terminal equipment by the data types of the terminal equipment, so that an instance of the equipment terminal is obtained on the simulation platform. Furthermore, the behavior simulation of the terminal equipment can be performed on the simulation platform, and specifically, the state update, function call, time triggering and online and offline functions of the terminal equipment can be realized on the simulation platform by setting corresponding parameter values. Further, after the terminal equipment to be simulated is configured, a session interface between the current terminal equipment and the internet of things platform is selected, and the terminal equipment is processed through the session to obtain a corresponding session link, wherein the session link can be in a HttpMessage, mqttMessag format. In addition, connection creation of terminal equipment is realized, attribute values of the terminal equipment are compiled and decoded, and plug-ins required by the platform of the Internet of things are installed to realize data interaction and state maintenance functions of the terminal equipment. And then the packaged terminal equipment is sent to the Internet of things platform through the session link, so that the running condition of the terminal equipment in the track traffic scene is simulated on the Internet of things platform.
