[0032] In the manufacturing industry, a large number of sensors are needed to detect the working status of some manufacturing processes. For example, in the coating industry, up to 500 pressure gauges are required just to handle the electrophoresis process. Currently, the data reading method for sensors such as pressure gauges is usually done by manual visual reading, which is then recorded and filed.

[0033] Since pressure gauges and other sensors are widely distributed, manual inspection takes a long time and is prone to missed or incorrect readings.

[0034] In order to solve the above problems, the present application provides a sensor data acquisition system, and the specific embodiments and implementation methods are as follows:

[0035] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the sensor data acquisition system of the present application.

[0036] In this embodiment, the image acquisition device is arranged relative to the sensor so that the data dial of the sensor is located within the acquisition field of view of the image acquisition device. The image recognition device is connected to the image acquisition device and is used to receive the dial image acquired by the image acquisition device for the data dial, and recognize the dial image to obtain the sensor monitoring data. The data processing device is connected to the image recognition device and is used to receive the sensor monitoring data and perform data processing on the sensor monitoring data.

[0037] The sensor in this embodiment is a device that can sense, measure or detect the physical quantity of each device in the manufacturing or transportation industry and convert it into readable data. The coating industry is used as an example for specific description below. In this case, the sensor can be, for example, a pressure gauge used in the electrophoresis process to monitor the pressure data of the equipment, and the pressure gauge includes a data dial that displays the detection data.

[0038] An image acquisition device refers to a device that can capture visual information of the surrounding environment or a specific object and convert it into a digital image. The image acquisition device in this embodiment has the function of taking pictures and transmitting data remotely, and can be used to take the dial image of the data dial of the pressure gauge and transmit the taken dial image to the image recognition device.

[0039] An image recognition device is a device that extracts required information from an input image or video by analyzing and processing it. In this embodiment, the image recognition device is mainly used to recognize the dial image from the image acquisition device to obtain sensor monitoring data. Specifically, in this embodiment, it can be used to recognize the dial image of the pressure gauge obtained by the image acquisition device to obtain the pressure data detected by the pressure gauge.

[0040] Data processing equipment is a hardware or software system used to receive, process, analyze and store data in order to obtain useful information or perform specific operations from it. These devices can include computers, servers, dedicated data processing units, software programs, etc., which can process large amounts of data in an efficient manner to support various applications and business needs.

[0041] In this embodiment, the data processing device is mainly used to receive the sensor detection data from the image recognition device and analyze and process the data. Specifically, the pressure data recognized by the image recognition device is received and the data is processed and analyzed. For example, corresponding measures can be taken, such as adjusting process parameters or issuing alarms to ensure the stability of the production process and product quality. At the same time, the processed data will also be stored for subsequent report generation, trend analysis and other applications. It can be understood that the data processing device in this embodiment can be implemented based on the existing technology, so it will not be repeated here.

[0042] To facilitate understanding of this embodiment, in one example, an image acquisition device is placed near the location of the data dial of the sensor, and the data dial is ensured to be within the acquisition field of view of the image acquisition device, so as to ensure that the image acquisition device can accurately obtain a complete image of the data dial. Subsequently, by connecting an image recognition device to the image acquisition device, the image acquisition device can receive the dial image of the data dial and recognize it, thereby obtaining sensor monitoring data. The sensor monitoring data is then transmitted to a data processing device connected to the image recognition device for further analysis and application of the sensor monitoring data, thereby achieving effective control and optimization of the monitoring process.

[0043] It can be understood that this embodiment ensures the accuracy and reliability of the sensor monitoring data through the relative setting of the precise sensor data dial and the image acquisition device. The use of image recognition equipment realizes the intelligent collection and recognition of the sensor data dial. Compared with the manual meter reading method, the efficiency and accuracy of data acquisition are improved, and the omission or error of reading is avoided to a certain extent. In addition, the use of data processing equipment further optimizes the collation and analysis process of monitoring data, providing a reliable basis for subsequent decision-making.

[0044] Combination Figure 1 As shown, this embodiment continues to provide a sensor data acquisition system, referring to Figure 2 , Figure 2 This is a schematic diagram of the structure of the second embodiment of the sensor data acquisition system of the present application.

[0045] In this embodiment, the image acquisition device includes a shooting unit and a fill light unit. The shooting unit is responsible for shooting the data dial of the sensor, and the fill light unit fills the light for the shooting unit to ensure the clarity of the image of the dial of the sensor shot by the shooting unit.

[0046] Of course, in some of the embodiments, the image acquisition device further includes a power supply unit, which is connected to both the shooting unit and the fill light unit and is used to supply power to the shooting unit and the fill light unit.

[0047] Among them, the power supply unit adopts lithium battery.

[0048] Specifically, lithium batteries can be used to power the shooting unit and the fill light unit. Lithium batteries have a relatively high energy density, which means that they can provide a relatively long power duration, so that the device can work for a long time on a single charge. This embodiment preferably uses a 14505 lithium battery. After testing, the image acquisition device can achieve about 2,000 shooting operations using this lithium battery. If the shooting operation is performed at a shooting cycle of once a day, the image acquisition device can work for 5 years.

[0049] In addition, the image acquisition device may further include a switch and a timer, wherein the switch is disposed between the power supply unit and the shooting unit or the fill light unit, and the timer is used to control the switch to be turned on according to a preset shooting cycle. In one example, the switch is a magnetic switch.

[0050] The fast-response magnetic switch and reliable timer operation improve the efficiency and consistency of image acquisition, which can meet the business needs in the actual production and manufacturing process.

[0051] In general, the image acquisition device of this embodiment may include key components such as a power supply unit, a shooting unit, a fill light unit, a magnetic switch and a timer, thereby realizing an automated and timed image acquisition process. The fill light unit provides suitable lighting conditions for the shooting unit, ensuring that the shooting unit can obtain clear image data of the sensor data dial. At the same time, a lithium battery is used as a power supply unit to power the shooting unit and the fill light unit, ensuring a stable power supply. The timer and switch components realize the function of the shooting unit to regularly shoot the sensor data dial. Specifically, the timer controls the switch to be turned on according to a preset shooting cycle. At this time, the fill light unit fills the light for the shooting unit, and the shooting unit shoots and obtains the image data of the data dial.

[0052] Combination Figure 1 As shown, this embodiment continues to provide a sensor data acquisition system, referring to Figure 3 , Figure 3 This is a schematic diagram of the structure of the third embodiment of the sensor data acquisition system of the present application.

[0053] In this embodiment, the load balancer is connected to the image acquisition device, and is used to receive and forward the dial image acquired by the image acquisition device. The web server is connected to the load balancer, and is used to receive and forward the dial image acquired from the data dial, and the data receiving service unit is connected to the web server, and is used to receive and store the dial image from the web server.

[0054] Among them, the image recognition device is connected to the data receiving service unit, used to obtain the dial image from the data receiving service unit and upload the recognized sensor monitoring data to the data receiving service unit; the data processing device is connected to the data receiving service unit, used to obtain the sensor monitoring data from the data receiving service unit.

[0055] This embodiment provides an overall network architecture for an image acquisition device to transmit a dial image. In this embodiment, the dial image is transmitted to an image recognition device via a wireless network. Specifically, the image acquisition device can convert and package the image data into an HTTP request, and send the request to a load balancer. The load balancer can evenly distribute HTTP requests from multiple image acquisition devices to multiple web servers to ensure that each web server obtains a relatively uniform load and prevent a certain web server from being overloaded, thereby improving overall performance and stability. The web server is used to forward the HTTP request from the load balancer to a data receiving service unit. The data receiving service unit receives and parses the HTTP request, obtains and stores the dial image. Subsequently, the image recognition device can obtain the dial image from the data receiving service unit for identification, and upload the identified sensor monitoring data to the data receiving server, so that the data processing device obtains and processes the sensor monitoring data from the data receiving server.

[0056] Further, see Figure 4 , this embodiment continues to provide a specific network architecture diagram of a sensor data acquisition system.

[0057] like Figure 4 As shown, the dial image collected by the image acquisition device is transmitted to the Nginx server cluster through SLB (Server Load Balance) in the Internet environment in the form of HTTP request, and then the Nginx server cluster forwards the HTTP request to the HTTP to HTTPS proxy server cluster, and the proxy server cluster converts HTTP to HTTPS. Then, the HTTP to HTTPS proxy server cluster forwards the HTTPS request to the ingress cluster through ELB (Elastic Load Balancer) in the VPC (Virtual Private Cloud) network environment, and the ingress cluster forwards the HTTPS request to the database receiving service unit in the local area network environment, wherein the receiving service unit includes an image receiving server for receiving and converting HTTPS requests, a file storage OBS (Object Storage Service) for storing dial images, and a MySQL database cluster for storing data information.

[0058] In this network architecture, SLB acts as a load balancer and can intelligently distribute HTTP requests issued by various image acquisition devices to servers with lighter loads according to the load conditions of each server in the Nginx server cluster, thereby ensuring that the resources of all servers are fully utilized.

[0059] As a Web server and reverse proxy server, Nginx server can not only provide high-performance Web services, process and forward received HTTP requests, but also balance the request distribution between servers through load balancing algorithm, thereby improving the performance and reliability of the entire system. Specifically, the image acquisition device actually communicates with Nginx instead of directly communicating with the backend server, which realizes the isolation of the image acquisition device and the image receiving server and improves the security of the system. Nginx also supports HTTP caching, which can reduce the number of requests to the image receiving server and improve performance.

[0060] The HTTP to HTTPS server can convert the insecure HTTP requests sent from the image acquisition device into secure HTTPS requests, and protect the security of the data by encrypting the data transmission.

[0061] ELB provides functions similar to SLB. It is responsible for receiving HTTPS requests and distributing them to image receiving servers to achieve load balancing, avoid overloading of a server, and improve the performance and reliability of the entire system.

[0062] Ingress can control external traffic access to services in the cluster according to preset rules, ensuring that only authorized users and agents can access, while routing traffic to different image receiving services. Ingress can also be combined with the Nginx proxy server to provide a certain degree of network security, including preventing DOS attacks and limiting access to specific protocols and ports.

[0063] Among them, ELB and Ingress are deployed in the VPC environment. VPC provides a logically isolated network environment, which can further control the inflow and outflow of traffic through network security groups, network ACL (Access Control List) and other functions, providing an additional security layer.

[0064] The data receiving service unit includes an image receiving server, a file storage OBS, and a MySQL database cluster. The image receiving server is used to receive and parse incoming HTTPS requests, obtain and store dial images, and the dial images will be saved in the file storage OBS. The image recognition device can obtain and recognize the dial image from the file storage OBS, obtain the sensor monitoring data, and save the data to the MySQL database. The data processing device can obtain the sensor monitoring data from the MySQL database and perform analysis and processing to obtain the status data of the industrial equipment monitored by the sensor, and store the status data in the MySQL database. Among them, the MySQL database is divided into a master database and a slave database. The slave database is responsible for backing up the data stored in the master database to ensure data security and avoid data loss.

[0065] Further, see Figure 4 This embodiment also provides a data display service, which is used to visualize the status information generated by the data processing device through the data display device, so as to facilitate the operation and maintenance personnel to pay attention to the status of the industrial equipment monitored by the sensor in real time. Figure 5 As shown, Figure 5 The final display interface of analyzing the dial data of the pressure gauge of the coating process device using the sensor data acquisition system of the present application is shown. The left side of the interface shows the distribution locations of various devices of the coating process. Users can view the pressure gauge analysis data of the device by clicking on a specific location.

[0066] In this embodiment, the image recognition device, data processing device, data receiving service unit and data display service are all deployed in the company's internal LAN. The above VPC can be connected to the enterprise's LAN through VPN or direct connection, etc., to achieve hybrid cloud deployment, so that the enterprise's internal network and cloud resources can access each other. At the same time, the data display device can also be connected to the data display service through the ELB and Ingress deployed under the VPC to ensure the security of data transmission.

[0067] This embodiment provides a secure network architecture for the deployment of the sensor data acquisition system. Through components such as Nginx server, SLB, HTTP to HTTPS proxy server, VPC, ELB, Ingress, etc., secure data transmission and access from data acquisition to storage and display are achieved. The security of data transmission is guaranteed, the efficiency and accuracy of industrial equipment monitoring are effectively improved, and reliable technical support is provided for the production and operation of enterprises.

[0068] In combination with the above embodiments, the sensor data acquisition system of the present application realizes efficient industrial equipment monitoring and data processing. Through precise data dial acquisition and image recognition technology, the accuracy and continuity of data acquisition are improved, and the errors of manual reading are avoided. At the same time, with the optimization of cloud computing and network architecture, safe and stable data transmission and processing are realized, providing a reliable technical foundation for enterprise production operations, and effectively improving production efficiency, product quality and equipment monitoring accuracy.

[0069] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. All equivalent structural changes made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present application.
