In addition, similar numbers in the figures are used to represent similar components, where:

[0044] Figure 1 is a schematic diagram of the main step flow of the method for local deployment of the industrial equipment monitoring software according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0045] Some embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0046] In the description of the present invention, "module" and "processor" may include hardware, software, or a combination of both. A module may include a hardware circuit, various suitable sensors, communication ports, memory, and may also include a software part, such as program code, or a combination of software and hardware. A processor may be a central processing unit, a microprocessor, an image processor, a digital signal processor, or any other suitable processor. The processor has data and / or signal processing functions. The processor can be implemented in software, in hardware, or in a combination of both. A non-transitory computer-readable storage medium includes any suitable medium for storing program code, such as a magnetic disk, a hard disk, an optical disk, a flash memory, a read-only memory, a random access memory, and so on. The term "A and / or B" represents all possible combinations of A and B, such as only A, only B, or A and B. The term "at least one A or B" or "at least one of A and B" has a meaning similar to "A and / or B" and may include only A, only B, or A and B. The singular terms "a" and "this" may also include the plural form.

[0047] Refer to the attached Figure 1 , Figure 1It is a schematic diagram of the main step flow of the method for localizing the deployment of industrial equipment monitoring software according to an embodiment of the present invention. As Figure 1 shown, the method for localizing the deployment of industrial equipment monitoring software in the embodiment of the present invention mainly includes the following steps S101 - step S105.

[0048] Step S101: Install the industrial equipment monitoring software according to the operating system. Among them, the installation content includes the installation of a Web application server;

[0049] In one implementation, the operating system includes the Windows system. When installing the software in the Windows system, it specifically includes:

[0050] Install the MySQL database. Since the default storage location of MySQL is the C drive, in the present invention, the data storage files installed by default in mysql are moved from the C drive to other drives. The purpose is to prevent the C drive space from being occupied in the future if the industrial data volume is too large, affecting the smoothness of the operating environment and the use of other software; it also includes a series of configurations for the database, including but not limited to the installation and configuration of Navicat, Redis, and jdk;

[0051] Install the Web application server, that is, the Tomcat server, which is mainly used for project deployment, to establish connections and communicate data between the industrial monitoring-related devices involved in the monitoring, configure the main functions of the project, and establish a dependency relationship with the database.

[0052] In one implementation, the operating system includes the Linux system. When installing and configuring the software in the Linux system, it specifically includes:

[0053] Install the remote control tool and the JDK development environment; the remote control tool is, for example, xshell. Xshell can be used to access the servers under different remote systems in the Windows interface, so as to better achieve the purpose of remotely controlling the terminal. Therefore, if the server is a Linux system and the terminal is a Windows operating environment, the remote control tool can be remotely compatible; the JDK development environment provides the operating environment;

[0054] Install the MySQL database and configure the data storage path to the specified storage space, the same as the above Windows system; it also includes but not limited to the installation of Redis;

[0055] Install the Web application server, that is, the Tomcat server, with the same function as the above Windows system.

[0056] Step S102: Obtain the project files. Among them, the project files include the front-end project files and the back-end project files;

[0057] In one embodiment, the background service project is a backend project named JYXServer, which mainly has two functions. One is to interact with the web project and provide various business interfaces based on the HTTP protocol to the web side; the other is to integrate various acquisition driver modules, mainly to interact with various collectors and various gateways, such as LoRa gateways, ZigBee gateways, Bluetooth gateways, MQTT services, Modbus services, etc., to provide functions such as data acquisition, data analysis, and data storage. When deploying, this project can be packaged into a JYXServer.war package through a development tool.

[0058] In one embodiment, the front-end project is a project architecture established with the name of web. The packaged deployment file is designed to be placed in the web folder under the Tomcat server. This front-end project interacts with the background project through the HTTP protocol, sends requests such as GET or POST to the background, and accesses various business interfaces.

[0059] Step S103: Configure the backend project files to the corresponding directory in the Web application server to complete the deployment of the backend project. Among them, the Web application server is configured to automatically generate the corresponding backend project folder;

[0060] Place the backend project files to be updated in the corresponding directory in the Web application server to complete the upgrade of the backend project. Among them, the Web application server is configured to automatically regenerate the corresponding backend project folder;

[0061] In one embodiment, the backend localization project mainly uses the Tomcat server. The webapps directory of this server is the location for storing Web applications. When deploying a Web application to Tomcat, usually the war / jar file of this application is placed in this directory, and Tomcat will automatically decompress and deploy it. Therefore, when deploying the backend project, place the JYXServer.war in the webapp directory under tomcat, and tomcat will automatically generate the corresponding JYXServer folder. If it is not generated, please restart the tomcat service; the JYXServer folder automatically decompressed by tomcat can be seen under the webapps folder. In the present invention, the Tomcat server is open source and free, can be freely used in any environment; it is lightweight, with a core of only a few hundred K and a very fast startup speed; it is easy to install and configure; it supports multiple operating systems; it has higher security, high reliability and stability.

[0062] In one embodiment, the backend project file is updated: the backend project file to be updated is placed in the corresponding directory of the Web application server to complete the backend project upgrade. Specifically, when the backend is upgraded, the JYXServer.war to be updated is placed in the webapp directory under tomcat, directly overwriting the original JYXServer.war. Tomcat will automatically regenerate the corresponding JYXServer folder. If it is not regenerated, please restart the tomcat service; the JYXServer folder automatically decompressed by tomcat can be seen under the webapps folder (the modification date will become the latest date).

[0063] Step S104: Deploy the front-end project file separately in the Web application server;

[0064] In this embodiment, the front-end and backend projects are deployed separately. The front-end project file is deployed separately in the web folder to achieve decoupling of the front-end and backend.

[0065] In one embodiment, when the front-end project is upgraded, the front-end project file to be updated is copied to the originally separately deployed folder to replace the original corresponding front-end project, completing the front-end project upgrade. Specifically, the old web folder under the webapp directory is deleted and replaced with a new web folder. It should be noted that if only some front-end project files in the Web folder are updated, these updated front-end project files are directly copied to the web and overwrite the original files.

[0066] Step S105: In response to the user login instruction, enter the industrial equipment monitoring software interface, add industrial equipment and wait for the sensor to automatically wake up and upload the status value, and then add the corresponding sensor in the industrial equipment monitoring software to complete the deployment.

[0067] In one embodiment, the software is mainly in the form of a web page. After logging in successfully by entering the access address, account password through a browser, it is presented to the customer for use. After the server is successfully started, add industrial equipment and wait for the sensor to automatically wake up and upload the status value, and then enter the "sensor management" interface of the website to add a sensor by entering the "sensor number". (If it prompts that the addition fails, it may be that the sensor has not woken up and uploaded the status value).

[0068] In one embodiment, after the industrial equipment monitoring software is deployed, it can display the connected devices in real time, including: displaying the latest operating status of sensors, historical alarm data, national distribution locations, etc. on a large screen; statistical overview, the number of sensor alarms, details of the latest characteristic values, characteristic values, waveform historical trends; alarm records, historical alarm records of sensors, alarm handling status, handling results, handling details; waveform records, real-time display of devices, historical waveform records and waveform details of sensors; and the industrial equipment monitoring software can perform area management, add and view each monitored area. At the same time, it can perform sensor management, view the current sensor list, sensor configuration information, and add and bind sensors.

[0069] Based on the above steps S101 - S105, the industrial equipment monitoring software of the embodiment of the present invention is locally deployed, which can meet the requirements of industrial equipment data protection. The device data cannot be accessed from the external network and can only be accessed within the local area network. Moreover, through local deployment, the network transmission data rate is fast, meeting the timely needs of monitoring data in the Internet of Things industry. At the same time, when the present invention is deployed, by directly separating and configuring the installation of the front-end project file and the back-end project file, it can be directly updated in the Web application server to achieve front-end and back-end decoupling, separation of dynamic resources and static resources, improving performance and scalability. And industrial equipment can be directly added to the corresponding sensors at the front end. The deployment process is simple, the deployment efficiency is high, and the upgrade is convenient.

[0070] It should be noted that although the above steps are described in a specific order in the above embodiments, those skilled in the art can understand that in order to achieve the effects of the present invention, different steps do not necessarily have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders, and these changes are all within the protection scope of the present invention.

[0071] Furthermore, the present invention also provides an industrial equipment monitoring software deployment system, including:

[0072] A data acquisition module;

[0073] A local server with a database, and the data collected by the data acquisition module is processed and stored in the database;

[0074] A client that configures the local server and the data acquisition module by performing the above-mentioned industrial equipment monitoring software local deployment method.

[0075] In one embodiment, the data acquisition module transmits the basic data of the underlying device. The data acquisition module, the local server, and the client constitute the localized deployment network architecture of the present invention. This network architecture is an internal local area network architecture. The data of the internal local area network devices cannot be accessed by the external network and can only be accessed within the local area network, achieving data protection and maintaining network security. At the same time, with the help of the local area network, software programs can also be shared. The transmission rate of the local area network is fast, meeting the requirements of the industrial Internet of Things industry.

[0076] In one embodiment, the system further includes a gateway. The gateway and the local server establish a TCP connection through the acquisition driver. After the connection is successful, the acquisition driver can obtain the channel of the corresponding gateway. Secondly, the data acquisition module, such as a sensor, is automatically identified and bound to the gateway through the set transmission frequency band, reception frequency band, and AES key. After the binding is successful, the sensor will transmit the collected data through the corresponding gateway and upload it to the local server. The acquisition driver of the local server will perform verification after receiving the data. After the verification is successful, the data will be stored in the database. The sensor collects the device data and enters the local server. The user can access the "Industrial Equipment Monitoring Software" through the web address (the address and port number can be set according to the user's server).

[0077] In one embodiment, after the software local server is successfully deployed and installed, the customer can read the data in the MySQL database through the provided standard API interface; or directly read the data in the MySQL database.

[0078] Furthermore, the present invention also provides an industrial equipment monitoring software deployment device, including a memory, one or more processors, and one or more application programs. Among them, the one or more application programs are stored in the memory, and when the one or more application programs are configured to be called by the one or more processors, the one or more processors are caused to execute the method described in the above technical solutions of steps S101 - S105.
