[0057] In order to make the objectives, technical solutions and advantages of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0058] During the production process of filter rods, the quality of filter rods directly affects the overall performance of cigarettes and the user experience. Traditional filter rod detection devices usually adopt an independent structure or a local area network communication mode, and this method has the following limitations:

[0059] Insufficient real-time performance: The data transmission delay between the detection device and the monitoring system is relatively large, making it difficult to meet the real-time quality monitoring requirements in a complex production environment.

[0060] Lag in fault response: The existing system has a slow response speed to equipment abnormalities, which may affect production efficiency, pose quality risks, and even cause greater economic losses.

[0061] In recent years, the Internet of Things technology has developed rapidly. In particular, the MQTT protocol (Message Queuing Telemetry Transport) has been widely used in the industrial Internet of Things scenarios due to its lightweight, efficient, and low-bandwidth environment support characteristics. The MQTT protocol realizes efficient data transmission and collaborative work among devices through the publish / subscribe mechanism. However, most of the existing solutions based on the MQTT protocol are highly general and lack specialized optimization for the monitoring requirements of filter rod detection devices in the filter rod industry. For example, there are still deficiencies in supporting high-frequency data acquisition, real-time anomaly alerts, and multi-device collaborative management.

[0062] Therefore, developing a monitoring system for cigarette filter rod detection devices based on the MQTT protocol can not only significantly improve the real-time performance and reliability of data transmission but also meet the requirements of multi-device efficient collaboration and centralized management, providing intelligent and digital support for the filter rod production process.

[0063] The filter rod detection method based on the MQTT protocol provided in the embodiments of this application can be applied to an application environment as Figure 1 shown. Among them, the filter rod detection device 102 communicates with the web server 106 through the relay server MQTT server 104. The data storage system can store the data that the server 106 needs to process. The data storage system can be integrated on the web server 106, or placed in the cloud or other network servers.

[0064] The filter rod detection device 102 performs detection on the target cigarette filter rod to obtain corresponding detection data, generates an XML data string based on the detection data and the operating information of the filter rod detection device 102, and then encapsulates a JSON data packet according to the XML data string and the device identifier of the filter rod detection device 102. The topic format of the JSON data packet is platformTopic (platform topic) and MAC address. Here, the MAC address is the device address of the filter rod detection device 102. The filter rod detection device 102 uploads the JSON data packet to the MATT server 104 through the MQTT protocol. The MATT server 104 forwards the JSON data packet to the web server 106. After receiving it, the web server 106 processes the JSON data packet to obtain the detection data of the target cigarette filter rod, the status information, and the alarm information of the filter rod detection device 102. Among them, the server 104 can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0065] In an exemplary embodiment, as Figure 2 shown, a filter rod detection method based on the MQTT protocol is provided. This method is applied toFigure 1 Taking the web server 106 in as an example, the following steps S201 and S202 are included. Among them:

[0066] Step S201: Receive the JSON data packet forwarded by the MQTT server. The MQTT server is used to receive the JSON data packets uploaded by each filter rod detection device through the MQTT protocol. The JSON data packet is encapsulated based on the XML data string and the identification information of the filter rod detection device. The XML data string is generated according to the operation information of the filter rod detection device and the detection data of the target cigarette filter rod detected by the filter rod detection device. The topic format of the JSON data packet is platformTopic and the MAC address, and the MAC address is the device address of the filter rod detection device.

[0067] Among them, the MQTT server can be understood as a data transmission transfer station. The data transmitted into the MQTT server can only be through the MQTT protocol. The MQTT protocol can be understood as a lightweight message transmission protocol based on the publish-subscribe mode. The JSON data packet can be understood as a lightweight data exchange format. The XML data string can be understood as a data document composed of elements, attributes, text, etc., with strict format requirements. The operation information can be understood as the status information, timestamp, etc. of the filter rod detection device.

[0068] Optionally, when the filter rod detection device 102 detects the target cigarette filter rod, it collects the detection data once for each detected sample. The collected detection data includes but is not limited to parameters such as filter rod length, diameter, and draw resistance. An XML data string is generated according to the collected detection data and the operation information of the filter rod detection device 102. Then, a JSON data packet with the topic format of platformTopic and the MAC address is encapsulated based on the XML data string and the device identification of the filter rod detection device, and the JSON data packet is reported to the MQTT server 104 through the MQTT protocol. The MQTT server 104 forwards the JSON data packet to the web server.

[0069] Based on the above implementation, by introducing the MQTT server as a transfer station for relevant detection data packets, it is ensured that the detection data detected by the filter rod detection device can be transmitted to the web server completely and effectively. And using the MQTT protocol to achieve data transmission also ensures the high efficiency of data transmission, thereby ensuring the timeliness of the data received by the web server.

[0070] Step S202: Process the JSON data packet to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information.

[0071] Among them, data processing can be understood as steps such as data packet parsing, data classification, and comprehensive analysis of the classified data. Status information can be understood as the device status information of the filter rod detection device, including device online, device offline, and maintenance status, etc. Alarm information can be understood as alarm information for the device and / or alarm information for the data.

[0072] Exemplarily, the web server 106 uses a pre-set parsing library to parse the JSON data packet to obtain the parsed data, and then classifies the parsed data according to a predefined format or field name to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information, and returns the detection data, status information, and alarm information to the user terminal. The user terminal displays the detection data, status information, and alarm information through a visual interface.

[0073] According to the above embodiments, through the data processing and data analysis of the web server, the detection results for the filter rod detection device can be quickly obtained, including the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information, and are returned to the user terminal for display through a visual interface, ensuring the timeliness of detection, enabling timely response to equipment abnormalities, and thus ensuring production quality and efficiency.

[0074] In the above filter rod detection method based on the MQTT protocol, the filter rod detection device detects the target cigarette filter rod, generates an XML data string based on the detection data obtained from its own operation and detection, encapsulates the XML data string and the device identification information into a JSON data packet with the topic format of platformTopic and the MAC address, and uploads it to the MQTT server based on the MQTT protocol. The MQTT server forwards the JSON data packet to the web server, and the web server processes the JSON data packet (JavaScript Object Notation) to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information. By introducing the MQTT server as a relay server for realizing the detection of the target cigarette filter rod and using the MQTT protocol to realize data transmission between multiple terminals, the real-time nature of data transmission is achieved, and thus the timeliness of filter rod detection is ensured.

[0075] In one embodiment, data processing is performed on the JSON data packet to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information, including: parsing the JSON data packet based on a pre-set parsing library to obtain the parsed data; classifying the parsed data according to a predefined format or field name to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information and storing them.

[0076] Optionally, the web server 106 parses the JSON data packet based on a pre-set parsing library to obtain the parsed data, and then classifies the parsed data according to a predefined format or field name to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information and stores them in the database. For example, classifying the data according to the field names: Detection data: the values in the "data" field, such as "weight", "circumference", "length". Status information: the values in the "status" field, such as "normal" or "error". Alarm information: the values in the "alert" field, such as "code" and "message".

[0077] According to the above embodiment, the web server parses the JSON data packet by using a pre-set parsing library, and classifies the parsed data by using a predefined format and field name to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information. Performing the above data processing on the JSON data packet and storing it in the database ensures the reduction of the original data and speeds up the detection progress, ensuring the reliability and real-time nature of the detection results, and storing them in the database for historical data query and analysis.

[0078] In one of the embodiments, the method further includes: generating a data table based on the numerical data and categorical data in the detection data, and generating a data chart based on the numerical data, categorical data, and ordinal data in the detection data, and returning them to the user terminal; the user terminal is used to display the data table and the data chart through a visualization interface.

[0079] Among them, the numerical data can be understood as data composed of clear Arabic numerals, such as length, weight, mixing ratio, etc., which can be subjected to mathematical operations and analysis. The categorical data can be understood as data used to describe the categories and attributes of things, such as the category of cigarette filter rods, regional classification attribute data, etc. The ordinal data can be understood as data with an inherent order, such as grade, ranking, etc.

[0080] Exemplarily, the web server 106 generates a data table based on the numerical data and categorical data in the detection data, and generates a data chart based on the numerical data, categorical data, and sequential data in the detection data. There may or may not be a corresponding relationship between the data table and the data chart. The generated data table and data chart are returned to the user terminal, and the user terminal displays the data table and data chart through a visualization interface.

[0081] Based on the above embodiments, by generating a data table according to the numerical data and categorical data in the detection data, and generating a data chart based on the numerical data, categorical data, and sequential data in the detection data, and returning them to the user terminal for display through a visualization interface, data tables and data charts with more intuitive and clear expression ways are generated using the detection data, which helps users improve the acquisition speed of the detection data and facilitates the control of the production efficiency and quality of the product.

[0082] In an exemplary embodiment, the method further includes: returning the status information of the filter rod detection device to the user terminal; the user terminal is used to display the status information through a visualization interface; generating a pop-up prompt message or a visual prompt message based on the alarm information, and returning it to the user terminal; the user terminal is used to display the pop-up prompt message or the visual prompt message through the visualization interface.

[0083] Among them, the visual prompt message can be understood as the alarm information processed by highlighting, bolding, or using a conspicuous color such as red.

[0084] Optionally, the web server 106 returns the status information of the filter rod detection device to the user terminal, and the user terminal displays the status information through a visualization interface, including displaying the online, offline, and maintenance status of the filter rod detection device, and generating a pop-up prompt message or a visual prompt message based on the alarm information, and returning it to the user terminal, and the user terminal displays the pop-up prompt message or the visual prompt message through the visualization interface.

[0085] According to the foregoing embodiments, the web server generates a pop-up prompt message or a visual prompt message based on the alarm information, and returns the generated pop-up prompt message or visual prompt message and the status information of the filter rod detection device to the user terminal. The user terminal realizes the display of the status information, pop-up prompt message, or visual prompt message through the visualization interface. By displaying the status information of the filter rod detection device, users can monitor the online status of the device in real time, control the detection process, and avoid the ineffective increase in costs. Secondly, generating a pop-up prompt message or a visual prompt message based on the alarm information and returning it to the user terminal, and also displaying it through the visualization interface, improves the technical effect of realizing the alarm of the alarm information, thereby helping users respond quickly to the failure, and further improving the reliability and practicality of the filter rod detection process.

[0086] In one embodiment, the method further includes: determining whether the detection data is within a preset qualified range; generating a control instruction based on the determination result and sending it. The filter rod detection device receives the control instruction sent by the web server by subscribing to a topic including the device address of the filter rod detection device.

[0087] Exemplarily, the web server 106 performs a quality judgment on the detection data, determines whether the detection data is within a preset qualified range, generates a control instruction based on the determination result and broadcasts it. The filter rod detection device 102 receives the control instruction sent by the web server by subscribing to a topic including the device of the filter rod detection device 102.

[0088] Based on the above embodiments, by performing a quality judgment on the detection data, generating a control instruction based on the judgment result, and broadcasting the control instruction, the filter rod detection device needs to subscribe to a topic including its own device address in order to successfully receive the corresponding control instruction, thereby realizing the smooth control of the detection process, avoiding the wrong control of the control instruction, and achieving the technical effects of improving production efficiency and product quality.

[0089] In an exemplary embodiment, as Figure 3 shown, a filter rod detection method based on the MQTT protocol is provided. Taking the method applied to the filter rod detection device 102 in Figure 1 as an example, it includes the following steps S301 to S303. Wherein:

[0090] Step S301, obtaining the detection data of the detected target cigarette filter rod.

[0091] Step S302, generating an XML data string based on the operation information and detection data of the filter rod detection device, and encapsulating a JSON data packet with the theme format of platformTopic and the MAC address according to the XML data string and the identification information of the filter rod detection device; the MAC address is the device address of the filter rod detection device.

[0092] Optionally, when the filter rod detection device 102 detects the target cigarette filter rod, it collects the detection data once for each detected sample. The collected detection data includes but is not limited to parameters such as the length, diameter, and draw resistance of the filter rod. The filter rod detection device 102 processes the operation information (device status information, timestamp, etc.) and detection data of the filter rod detection device 102 to form an XML format data string, and encapsulates a JSON data packet according to the XML data string and the device identification of the filter rod detection device. The theme format of the JSON data packet is platformTopic / MAC address, where the MAC address is the unique identification of the filter rod detection device.

[0093] Based on the above embodiments, the filter rod detection device encapsulates the collected data into a unified data format including device identification, timestamp, detection items and values, preparing data for subsequent data reporting. By means of data encapsulation, the independence of various types of data is ensured, and at the same time, compression and encapsulation also ensure the security and integrity of the data itself during the transmission process.

[0094] Step 303, upload the JSON data packet to the MQTT server through the MQTT protocol; the MQTT server is used to receive each JSON data packet and forward the JSON data packet to the web server whose subscribed topic includes platformTopic; the web server is used to process the JSON data packet to obtain the detection data of the target cigarette filter rod, the status information and alarm information of the filter rod detection device.

[0095] Exemplarily, the filter rod detection device 102 uploads the JSON data packet to the MQTT server 104 through the MQTT protocol. The MQTT server 104 receives each JSON data packet and forwards the JSON data packet to the web server 106 whose subscribed topic includes platformTopic. The web server 106 processes the JSON data packet to obtain the detection device of the target cigarette filter rod, the status information and alarm information of the filter rod detection device.

[0096] Based on the above embodiments, the JSON data packet is uploaded to the MQTT server through the MQTT protocol. The MQTT server forwards the JSON data packet to the web server, and the web server performs data processing to achieve detection. Through the MQTT protocol, low-latency and highly reliable data transmission is achieved, ensuring the real-time performance and stability of the monitoring system.

[0097] In one of the embodiments, as Figure 4 shown, a filter rod detection system based on the MQTT protocol is provided. The system includes a filter rod detection device, an MQTT server and a web server;

[0098] The filter rod detection device is used to obtain the detection data of the detected target cigarette filter rod; generate an XML data string based on the operation information and detection data of the filter rod detection device, and encapsulate a JSON data packet with the topic format of platformTopic or MAC address according to the XML data string and the identification information of the filter rod detection device; the MAC address is the device address of the filter rod detection device;

[0099] The filter rod detection device is also used to upload the JSON data packet to the MQTT server through the MQTT protocol;

[0100] An MQTT server, which is used to receive each JSON data packet and forward the JSON data packet to a web server whose subscribed topic includes platformTopic;

[0101] A web server, which is used to process the JSON data packet to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information.

[0102] Exemplarily, the filter rod detection device acquires the detection data of the detected target cigarette filter rod, generates an XML data string based on the operation information and detection data of the filter rod detection device, and encapsulates a JSON data packet with a topic format of platformTopic or MAC address according to the XML digital string and the identification information of the filter rod detection device, where the MAC address is the device identification of the current filter rod detection device, uploads the JSON data packet to the MQTT server through the MQTT protocol, the MQTT server receives each JSON data packet, and forwards the JSON data packet to a web server whose subscribed topic includes platformTopic, and the web server processes the JSON data packet to obtain the detection data of the target cigarette filter rod, the status information of the filter rod detection device, and the alarm information. Through the MQTT protocol, low-latency and high-reliability data transmission is achieved, ensuring the real-time performance and stability of the monitoring system, effectively monitoring the operation status of the filter rod detection device, promptly responding to device anomalies, and improving production efficiency and product quality.

[0103] In an exemplary embodiment, as Figure 5 shown, a specific implementation manner of a filter rod detection method based on the MQTT protocol is provided, where:
