[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] Different types of terminal devices and business systems are developed based on different technical architectures, programming languages, database systems, etc., resulting in different communication protocols and data formats between them. Therefore, when a new terminal device connects to a business system, the business system needs to perform system integration for that terminal device to ensure compatibility with its communication protocols and data formats.

[0050] Based on this, this application proposes the following technical solution, as detailed below:

[0051] In one embodiment, such as Figure 1 As shown, Figure 1 This is a flowchart illustrating a data communication method provided in an embodiment of this application. This application provides a data communication method applied to middleware software installed in a business system, specifically including the following:

[0052] S110: Receives transmission signals sent by terminal equipment or business systems and determines the transmission content carried by the transmission signals.

[0053] In this embodiment, users can use middleware software to connect terminal devices and business systems, responsible for receiving data and commands sent by various terminal devices and business systems, and then forwarding the data. Upon receiving a transmission signal from a terminal device or business system, the middleware software can first determine the content carried by the transmission signal and then perform corresponding processing operations. This isolates the underlying details of the communication protocols used by various types of data, improving the compatibility of the business system.

[0054] It is understood that the business system in this application can connect to different types of terminal devices, thereby enabling data communication between these devices. In one application scenario, the terminal devices include, but are not limited to, attendance devices, access control devices, and payment devices. Furthermore, each type of terminal device can be categorized into multiple interaction types, such as facial recognition, card swiping recognition, and fingerprint recognition.

[0055] It should be noted that, due to the bottom design of various terminal devices, the implementation functions are different, the communication interfaces adopted are different, each interface has its specific communication protocol and specification. Based on this, the application can adopt middleware software to realize the data communication between each terminal device and the business system, avoid the direct connection of the business system and each communication interface, and the middleware software can provide a unified API interface to encapsulate the bottom details of the communication with the terminal device, including various communication protocols and interfaces, so that the business system does not need to care about the specific communication protocol used by the terminal device, and does not need to deeply understand the complexity and specificity of the terminal device, thereby reducing the communication compatibility pressure of the business system.

[0056] Specifically, after receiving the transmission signal sent by the terminal device or the business system, the middleware software can analyze the transmission signal to obtain the transmission content carried by the transmission signal. The transmission content here can be related data reported by the terminal device to the business system, or related commands issued by the business system to the related device, which is not limited here. When the terminal device and the business system need to interact with data, the related data or commands need to be converted into a data format that the other party can receive through the middleware software, and then sent to the corresponding device or system, so as to avoid the incompatibility of the communication protocol.

[0057] Further, when the terminal device is connected to the business system for the first time through the middleware software, the middleware software can receive the device code, device type, supported communication protocol and other related device data provided by the terminal device, and then the middleware system can verify the device data and add it to the device management list after verification to communicate between the terminal device and the business system. In addition, the middleware software can also monitor the connection state of the connected terminal device. In detail, the terminal device will send a heartbeat data every 5 seconds, and the middleware software will monitor the heartbeat data of each terminal device through threads. If the time length of the monitoring heartbeat data exceeds the preset time length, the middleware software will update the connection state of the corresponding terminal device to offline.

[0058] S120: When the transmission content is the device initial data sent by the terminal device in real time, the device initial data is format-converted to obtain device state data, and the device state data is stored in the upload data queue.

[0059] In this embodiment, after the transmission content obtained by step S110 is analyzed, if the transmission content is the device initial data sent by the terminal device in real time, the middleware software can format-convert the device initial data to obtain device state data, and then the device state data can be stored in the upload data queue, so as to quickly respond when the business system needs to obtain the device state data of the terminal device.

[0060] The uploading data queue refers to a mechanism for temporarily storing to-be-sent data, so as to realize asynchronous processing of the device initial data, improve the corresponding capability and throughput of the terminal device, and further serve as a buffer to allow data to accumulate for a period of time without loss when the data generation speed exceeds the processing or sending speed, thereby improving the smoothness and stability of data communication.

[0061] Specifically, after receiving the device initial data sent by the terminal device in real time, the middleware software can analyze the device initial data to obtain the state result of the terminal device at the current time, and then convert the data format of the analyzed state result into a data format that can be received by the business system, so that the business system can quickly respond when it needs to obtain the device state data of the terminal device.

[0062] For example, the device initial data sent by the terminal device is binary data, and at this time, the middleware software can analyze the actual state represented by the binary data and then convert it into a text format that can be received and understood by the business system.

[0063] S130: When the transmission content is a data request sent by the business system, the device state data corresponding to the data request is obtained from the uploading data queue and returned to the business system as target data.

[0064] In this embodiment, after analyzing the transmission content obtained by step S110, if the transmission content is a data request sent by the business system, the middleware software can obtain the device state data corresponding to the data request from the uploading data queue and return it to the business system as target data, thereby improving the efficiency of data communication.

[0065] It can be understood that when the middleware software is deployed in the business system, the middleware software can be connected to the business system through an ESB (Enterprise Service Bus) after publishing the API interface. The ESB refers to a standard integration method between loosely coupled services and applications, which provides the most basic connection hub in the network and can solve the integration problem between enterprise application systems. Therefore, the middleware software can realize seamless integration and efficient data exchange between the terminal device and the business system through the ESB.

[0066] Specifically, when the business system requests data from the middleware software through the API interface, the API interface can be forwarded through the ESB. Further, the path format of the API interface includes two types of GET and POST, wherein the GET request is used to query data, and the POST request is used to submit data. Through the API interface, the business system can realize data communication with the terminal device.

[0067] S140: When the transmission content is an operation command issued by the service system, the operation command is stored in the device command queue.

[0068] In this embodiment, after the transmission content obtained by step S110 is analyzed, if the transmission content is an operation command issued by the service system, the middleware software can store the operation command in the device command queue, so that the terminal device can quickly obtain the operation command of the service system and execute it.

[0069] The device command queue refers to a data structure for storing and managing commands to be sent to the terminal device, which can ensure that the commands are processed and executed in a specific order, such as first-in-first-out, priority, etc., to avoid command conflicts or ensure that the dependent relationship of the commands is correctly processed. In addition, when the terminal device cannot temporarily process more commands, the device command queue can act as a buffer to avoid data loss or system crash, achieve data flow control and load balancing.

[0070] For example, when the user needs to manage the relevant data in the terminal device, the service system can generate the corresponding operation command, such as adding, deleting, querying or modifying the personnel information of the registered personnel in the terminal device, and then the service system can send the operation command to the middleware software in the form of a transmission signal, so that the middleware software stores it in the device command queue.

[0071] S150: When the transmission content is a command request sent by the terminal device, the operation command corresponding to the command request is extracted from the device command queue and returned to the terminal device as a target command, and after the terminal device executes the target command and obtains the execution result, the execution result is sent to the service system.

[0072] In this embodiment, after the transmission content obtained by step S110 is analyzed, if the transmission content is a command request sent by the terminal device, the middleware software can extract the operation command corresponding to the command request from the device command queue and return it to the terminal device as a target command, and after the terminal device executes the target command and obtains the execution result, the execution result can be sent to the service system.

[0073] Specifically, after the terminal device is online and a communication connection is established with the middleware software, the terminal device can send a command request to the middleware software at a preset frequency to obtain operation commands issued by the business system in a timely manner, so as to realize synchronization of data communication. When the middleware software forwards the operation commands to the terminal device, the middleware software can convert the operation commands to a data format that can be received by the terminal device based on the device information of the terminal device stored in the device management queue, and then forwards the operation commands to the terminal device. Then, the terminal device can execute the obtained operation commands, such as adding, deleting, querying, or modifying the personnel information of the registered personnel in the personnel management list, and generates corresponding execution results after the execution of the operation commands is completed, and returns the execution results to the business system through the middleware software.

[0074] In the above embodiment, after receiving the transmission signal sent by the terminal device or the business system, the middleware software can determine the transmission content carried by the transmission signal, so that the transmission content can be uniformly converted in format, the compatibility of the business system is improved, and the data transmission between the terminal device and the business system is quickly realized. For example, when the device initial data sent by the terminal device in real time is received, the device initial data can be converted in format to obtain device state data, and the device state data is stored in the upload data queue, so that when the data request sent by the business system is received, the device state data corresponding to the data request can be obtained from the upload data queue and returned to the business system as target data; and when the operation command issued by the business system is received, the operation command is stored in the device command queue, so that when the command request sent by the terminal device is received, the operation command corresponding to the command request can be extracted from the device command queue and returned to the terminal device as a target command, and after the terminal device executes the target command to obtain the execution result, the execution result is sent to the business system. Through the middleware software, the application can provide a unified communication interface to isolate the underlying details of the communication protocol to support data communication of various types of terminal devices and improve the compatibility of the business system.

[0075] In one embodiment, the format conversion of the device initial data in step S120 to obtain the device state data can include:

[0076] S121: performing a preprocessing operation on the device initial data, and performing state analysis based on the preprocessed device initial data to obtain a device state of the terminal device and a state type of the device state.

[0077] S122: determining a data receiving format of the business system and a device code of the terminal device, and performing data coding on the device state, the state type, and the device code based on the data receiving format to generate the device state data.

[0078] In this embodiment, when the middleware software performs format conversion on the device initial data, the middleware software can first perform a preprocessing operation on the device initial data, and perform state analysis on the preprocessed device initial data to obtain the device state of the terminal device and the state type of the device state. Then, the data receiving format of the business system and the device code of the terminal device can be determined, and the device state, the state type, and the device code are encoded based on the data receiving format to generate device state data that can be received by the business system, thereby improving the data communication efficiency.

[0079] The preprocessing operation includes but is not limited to noise removal, data cleaning, feature extraction and dimension reduction, and data normalization. In detail, the noise removal refers to removing noise and interference in the device initial data to improve the quality and availability of the data; the data cleaning refers to removing outliers, supplementing missing values, and smoothing the data to improve the accuracy and integrity of the data; the feature extraction and dimension reduction refer to extracting effective information from the device initial data and converting the extracted effective information into a low-dimensional vectorized form to facilitate subsequent mathematical operations and analysis; and the data normalization refers to normalizing the device initial data to ensure that the weights of different features are the same, thereby avoiding data bias and error.

[0080] Specifically, when determining the data receiving format of the business system, the middleware software can first obtain the business requirements of the business system, such as the expected data type, data structure, field name, and format, and then select the data receiving format supported by the business system, such as JSON, XML, CSV, etc., based on these business requirements. These data receiving formats have wide compatibility and are easy to parse and generate. Then, the middleware software can query the device code corresponding to the terminal device from the device management list, and then encode the device state and state type obtained by analyzing the device initial data and the device code based on the selected data receiving format to generate device state data that can be received by the business system.

[0081] It can be understood that the device initial data reported by the terminal device to the business system includes at least one state type, such as a door magnetic state, a relay state, or an alarm state. Therefore, the middleware system can analyze the device state of each state type in the device initial data, such as no door magnet or door magnet for the door magnetic state, and closing and opening for the relay state.

[0082] For example, the device initial data uploaded by the terminal device is binary data. In the device initial data uploaded by a door access device, Sensor represents the device type of a door magnetic state, each door occupies two binary bits, AA represents 1-4 doors, BB represents 5-8 doors, 1 door occupies the 1st and 2nd bits of the first byte, and so on, 0b00 represents that the current door magnetic has no door magnetic, 0b01 represents that the current door has a door magnetic and is closed, and 0b10 represents that the current door has a door magnetic and is opened; Relay represents the device type of a relay state, each door occupies one binary bit, 0b0 represents that the relay is attracted, 0b1 represents that the relay is disconnected, the first bit is the 1st door relay state, and so on; Alarm represents the device type of an alarm state, each 1 door occupies one byte, and a maximum of 8 alarms can be expressed, DD is the 1st door alarm state, and so on, wherein the alarm type can include an unexpected door opening event, a tamper alarm, a coercion password alarm, a coercion fingerprint alarm, a door magnetic timeout alarm, and the like.

[0083] In one embodiment, the step S130 of obtaining the device state data corresponding to the data request from the uploaded data queue and returning the device state data as target data to the business system can include:

[0084] S131: decoding information of the data request to obtain a first decoding result, and determining the device code and the state type corresponding to the data request according to the first decoding result.

[0085] S132: searching the device code and the state type in the uploaded data queue, and returning the searched device state data as target data to the business system.

[0086] In the embodiment, after receiving the data request of the business system, the middleware software can decode information of the data request to obtain a first decoding result, and determine the device code and the state type corresponding to the data request according to the first decoding result, so as to search the device code and the state type in the uploaded data queue, and return the searched device state data as target data to the business system, so as to realize quick response to the data request.

[0087] For example, in order to ensure the accuracy of the device state of the access control device displayed in the business system, the business system can send a data request of the access control device to the API interface of the middleware software every 5 seconds. Since the device state data stored in the upload data queue carries the device code and state type of the corresponding terminal device, after receiving the data request of the business system, the middleware software can obtain the device code and state type of the data request by analysis, retrieve the device state data of the access control device corresponding to the device code from the upload data queue, and then filter the device state data of the state type, such as the door magnetic state, the relay state, and the alarm state, from the retrieved device state data, and finally return the filtered device state data as target data to the business system.

[0088] In one embodiment, the step S150 of extracting the operation command corresponding to the command request from the device command queue and returning the operation command as a target command to the terminal device in step S150 can include:

[0089] S151: decoding the command request to obtain a second decoding result, and determining the device code corresponding to the command request according to the second decoding result.

[0090] S152: extracting the operation command corresponding to the device code from the device command queue according to the preset extraction number, and returning the operation command as a target command to the terminal device.

[0091] In this embodiment, after receiving the command request of the business system, the middleware software can decode the command request to obtain a second decoding result, determine the device code corresponding to the command request according to the second decoding result, and then extract the operation command corresponding to the device code from the device command queue according to the preset extraction number, and return the operation command as a target command to the terminal device.

[0092] It can be understood that since the operation commands stored in the device command queue carry the device code of the terminal device to be executed, after receiving the command request of the business system, the middleware software can obtain the device code of the command request by analysis, and then retrieve the operation command corresponding to the device code from the device command queue, which represents the operation command to be executed by the terminal device corresponding to the device code. Finally, the middleware software can extract the operation command consistent with the preset extraction number from the retrieved operation command as a target command and send it to the terminal device, so that the terminal device performs the operation on the target command.

[0093] It should be noted that the business system can simultaneously issue multiple operation commands to the same terminal device. To avoid the situation that the terminal device cannot simultaneously process more operation commands, causing communication congestion, the middleware software can send operation commands to the terminal device according to the preset extraction number, so as to realize data flow limiting and load balancing.

[0094] In one embodiment, the step S152 of extracting the operation commands corresponding to the device code from the device command queue according to the preset extraction number can include:

[0095] S1521: retrieving multiple operation commands corresponding to the device code in the device command queue to obtain a retrieval result; wherein each operation command corresponds to a priority.

[0096] S1522: determining the number of operation commands in the retrieval result, and judging whether the number of operation commands is greater than the preset extraction number.

[0097] S1523: if yes, extracting the operation commands corresponding to the preset extraction number from the retrieval result in the order from high to low priority.

[0098] S1524: if no, extracting each operation command in the retrieval result.

[0099] In this embodiment, after the middleware software decodes the device code of the command request, it can retrieve multiple operation commands corresponding to the device code in the device command queue to obtain a retrieval result. Then, the middleware software can determine the number of operation commands in the retrieval result, and judge whether the number of operation commands is greater than the preset extraction number, and then can perform corresponding extraction operation according to the judgment result.

[0100] Specifically, each operation command stored in the device command queue is associated with a priority. When the number of operation commands is greater than the preset extraction number, it means that the number of operation commands to be executed by the terminal device exceeds the number of operation commands that can be simultaneously executed by the terminal device. Therefore, the middleware software needs to perform data flow limiting, that is, extracting the operation commands corresponding to the preset extraction number from the retrieval result in the order from high to low priority, and sending the extracted operation commands to the terminal device as operation commands; when the number of operation commands is not greater than the preset extraction number, it means that the terminal device can simultaneously process the operation commands to be executed in the retrieval result. Therefore, the middleware software can extract each operation command in the retrieval result, and send the extracted operation commands to the terminal device as operation commands.

[0101] For example, the operation commands stored in the device command queue to be executed by the access control device are divided into emergency commands and non-emergency commands, wherein the priority of the emergency commands is higher than the priority of the non-emergency commands. Therefore, when the access control device requests its corresponding operation command from the middleware software, the middleware software can preferentially extract the emergency command from the device command queue and send it to the terminal device.

[0102] In one embodiment, the sending of the execution result to the business system in step S150 can include:

[0103] S153: determining the data receiving format of the business system, and sending the execution result to the business system after format conversion according to the data receiving format.

[0104] In this embodiment, after receiving the execution result returned by the terminal device, the middleware software can select a data receiving format, such as JSON, XML, CSV, etc., from a plurality of data receiving formats supported by the business system according to the business requirements of the business system; then the middleware software can format convert the execution result according to the selected data receiving format, and send the format converted execution result to the business system using a corresponding communication protocol, such as HTTP, HTTPS, SOAP, RESTful, etc., thereby improving the communication efficiency between the terminal device and the business system.

[0105] In one embodiment, the method can further include:

[0106] S160: before returning the target command to the terminal device, determining the data object type of the terminal device and the data receiving format of the data object type.

[0107] S170: format converting the target command according to the data receiving format, and sending the converted target data to the terminal device.

[0108] In this embodiment, before returning the target command to the terminal device, the middleware software can first determine the data object type of the terminal device and the data receiving format of the data object type, then format convert the target command according to the data receiving format, and send the converted target data to the terminal device.

[0109] It can be understood that various data object types in the terminal device are collected in the middleware software, and only data identical to these data object types can be received by the corresponding terminal device. Further, different terminal devices of different device types have different understandings of data object types, and therefore the middleware software can format convert the target command into a data receiving format corresponding to the data object type, so as to eliminate the inconsistency of the terminal device in understanding data.

[0110] In order to better explain the text matching method of the present application, the following will be further described by taking Figure 2 as an example, as shown in Figure 2 , Figure 2 is an interaction diagram of a data communication process provided by an embodiment of the present application.
