Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to an experimental instrument Internet of Things data acquisition system. Background Art

[0002] Existing laboratory instrument monitoring and management platforms usually use the instrument's operating switch data as the main basis to determine whether the instrument is running, the operating time, and the user, etc. These data are usually recorded by sensors or the instrument itself and sent to the management platform for processing and analysis.

[0003] However, the singleness of this data leads to a limited understanding of the operation of the experimental instrument. It is impossible to fully obtain the operation data and other effective information of the experimental instrument, such as temperature, humidity, pressure, current, voltage and other parameters, only through the operation switch data; these data are very important for evaluating the operation status, performance and fault detection of the instrument. In addition, the existing experimental instrument monitoring and management platform also has certain limitations in data analysis capabilities. Due to relying only on the operation switch data, the platform can often only provide simple statistical information, such as total operation time, average usage time, etc. For more complex data analysis and trend prediction and other advanced functions, the existing technology is insufficient and cannot fully obtain the operation data and other effective data of the experimental instrument, resulting in low instrument management efficiency and poor data analysis capabilities. In summary, although the existing experimental instrument monitoring and management platform plays a certain role in instrument management, its data singleness and data analysis capabilities have led to low instrument management efficiency and weak data analysis capabilities.

[0004] Therefore, it is necessary to design a new system to obtain more comprehensive and accurate experimental instrument operation data, while improving instrument management efficiency and data management and analysis timeliness. Utility Model Content

[0031] In this embodiment, the device end is used to generate experimental data; the data acquisition end is responsible for collecting experimental data; the gateway acts as a bridge for data transmission and management; the Internet of Things platform 50 receives and stores the experimental data transmitted from the data acquisition end through the gateway, and performs further analysis and processing; through the collaboration of the data acquisition end and the gateway, real-time monitoring and collection of experimental data can be achieved to ensure the timeliness and accuracy of the data; the gateway can encrypt the experimental data to ensure the security of the data during transmission; the Internet of Things platform 50 can realize remote storage and management of experimental data, making it convenient for users to view and analyze data at any time; the Internet of Things platform 50 provides data analysis functions, which can help users better understand experimental data, discover potential rules and optimize experimental processes.

[0032] In addition, the edge gateway 40 is an important component used to connect the experimental data collector 30. It is responsible for receiving the device-side experimental data collected by the camera 31, converting the video stream into a data stream, and then transmitting the data to other systems or devices. The role of the edge gateway 40 is to process and transmit experimental data to ensure the real-time and accuracy of the data; the universal gateway 41 is another key component used to connect the current detector 32 and the environmental information acquisition device 33. It is responsible for receiving and processing data from these devices and transmitting it to other systems or devices. The role of the universal gateway 41 is to integrate various types of data and provide a unified data interface. The two gateways play an indispensable role in the system. The flexible use of the two gateways also highlights the comprehensiveness and versatility of the system.

[0033] In one embodiment, see Figure 1 and Figure 2 The above-mentioned device end includes an experimental instrument 20; the experimental instrument 20 includes a display screen 21, and the experimental data collector 30 is connected to the edge gateway 40.

[0034] In one embodiment, the above-mentioned experimental data collector 30 also includes a processing chip, a serial port device and an analysis module.

[0036] The system of this embodiment is formed by upgrading the instrument management platform based on the Internet of Things. An edge gateway 40 and an experimental data collector 30 are added to transmit the experimental data of each instrument to the Internet of Things platform 50 through the edge gateway 40. The edge gateway 40 has the functions of storing data, analyzing data and transmitting data.

[0037] In this embodiment, if Figure 2 As shown, the camera 31 is facing the upper side opposite to the display screen 21 so as to capture the interface displayed on each display screen 21 . Specifically, one camera 31 can capture multiple display screens 21 .

In this case, the camera 31 can be installed above the side directly opposite the display screen 21, or in the direction directly opposite the display screen 21, and tilted at a certain angle to facilitate capturing the interface displayed by the entire display screen 21.

[0039] The camera 31 is used to obtain the real-time operating data on the display screen 21 of each experimental instrument 20, and the experimental data collector 30 converts the video information into transmittable data, which is then transmitted to the edge gateway 40 for processing. This process belongs to the existing technology and will not be repeated here; each experimental data collector 30 caches and analyzes the collected experimental data according to the equipment number, thereby realizing comprehensive monitoring and data collection of the experimental process.

[0040] After receiving the experimental data, the edge gateway 40 will encrypt and compress the data and then transmit it to the Internet of Things platform 50. Such a processing flow can ensure the security of the experimental data and improve the effect of data transmission. In addition, the edge gateway 40 can also control the access of the outside world to the physical interface of the edge gateway 40 by setting a password lock, biometric device and other physical barrier devices.

[0041] These security measures help prevent unauthorized visitors from obtaining experimental data or interfering with the edge gateway 40, thereby ensuring the integrity and confidentiality of the data. At the same time, encryption and compression processing also help improve the efficiency and stability of data transmission, providing more reliable data input for the IoT platform 50.

[0042] In one embodiment, an analog-to-digital converter is connected between the experimental instrument 20 and the experimental data collector 30 .

[0043] In one embodiment, a digital signal processor is connected between the experimental data collector 30 and the edge gateway 40 .

[0044] Since there are many types of experimental data and most of them are important, in order to ensure signal integrity and compatibility, an analog-to-digital converter, specifically an ADC converter, is configured between the experimental instrument 20 and the data collector to quickly convert analog signals into digital signals with high precision and convert and transmit analog signals with minimal error.

[0045] In addition, to ensure the accuracy and stability of data transmission, the experimental data collector 30 and the edge gateway 40 are preferably equipped with a digital signal processor, which is used to perform real-time filtering, compression and error correction on the digital signal to ensure the accuracy and stability of the data during data transmission.

[0046] In one embodiment, the edge gateway 40 further includes a data encryption module, which is used to encrypt the data stream transmitted by the experimental data collector.

[0047] The data encryption module is used to encrypt the data stream transmitted by the experimental data collector. This means that when the data is transmitted from the experimental data collector to the edge gateway, they will be encrypted to ensure that the data will not be stolen or tampered with by unauthorized access during transmission. The data encryption module can use various encryption algorithms, such as AES (Advanced Encryption Standard), RSA (asymmetric encryption algorithm), etc., to protect the confidentiality and integrity of the data.

[0048] By encrypting data, you can effectively protect the security of data and prevent sensitive information from being obtained by unauthorized visitors. Encrypting data helps comply with various privacy laws and regulations, especially when it comes to personally identifiable information or sensitive experimental data.

[0049] In one embodiment, the edge gateway 40 further includes a security identification module, and the security identification module includes a password lock or a biometric identification device.

[0050] The security identification module includes a password lock or a biometric device, which is used to authenticate and verify the access rights of the edge gateway. The password lock can use the traditional password input method, while the biometric device can authenticate the identity through biometric features such as fingerprint recognition and facial recognition.

[0051] Through the security identification module, only authorized users can access the edge gateway, effectively controlling access to critical systems.

[0052] Using the security identification module can prevent unauthorized individuals or malicious attackers from illegally accessing the system and improve the overall security of the system.

[0053] The data encryption module and security identification module add security protection measures to the edge gateway, ensuring the secure transmission of data and secure access to the system, thereby better meeting the needs of security and privacy protection.

[0054] In one embodiment, the above-mentioned environmental information collection device 33 includes at least one of a temperature and humidity sensor, a smoke sensor, an atmospheric pressure gauge, a vibration sensor and an infrared detector.

[0055] In this embodiment, the current detector 32 is connected to the universal gateway 41 to realize the collection and transmission of current data; the environmental information collection device 33 is also connected to the universal gateway 41 to collect environmental information and transmit it to the gateway.

[0056] In addition, the environmental information collection device 33 includes at least one of a temperature and humidity sensor, a smoke sensor, an atmospheric pressure gauge, a vibration sensor, and an infrared detector. These sensors can be used to monitor the temperature, humidity, smoke conditions, atmospheric pressure, vibration level, infrared radiation, and other information of the experimental environment.

[0057] In one embodiment, a digital signal processor is provided between the current detector 32 and the environment information acquisition device 33 and the universal gateway 41 .

[0058] In this embodiment, digital signal processors are provided between the current detector 32, the environmental information acquisition device 33 and the universal gateway 41. These digital signal processors can filter, compress and correct errors of the data collected by the sensors in real time to ensure the accuracy and stability of the data, and finally transmit the processed data to the gateway.

[0059] Through real-time processing by the digital signal processor, the accuracy and stability of data transmission are guaranteed, effectively reducing the error in the data transmission process. Integrating environmental information with experimental data helps to comprehensively monitor the experimental environment and improve the reliability and integrity of experimental data. As a data aggregation center, the universal gateway 41 can effectively manage and transmit various types of data, improving the overall operating efficiency and data management capabilities of the system.

[0060] In one embodiment, see Figure 1 The equipment end includes a laboratory 10; the data acquisition end and the experimental instrument 20 are both located in the laboratory 10. The laboratory 10 is provided with a plurality of experimental instruments, and the experimental data collector can collect display images of the display screens of the plurality of experimental instruments through a camera.

[0061] The data acquisition terminal is located in the laboratory 10, which is conducive to the centralized management and monitoring of data and convenient for experimenters to process and analyze data in a timely manner.

[0062] Since the experimental data collector can collect the display screens of multiple experimental instruments through the camera, it is possible to centrally manage and monitor multiple experimental instruments in the laboratory. This allows the experimenter to monitor and record the operation and data output of different experimental instruments at any time without having to go to each experimental instrument in person.

[0063] The system of this embodiment can store and analyze the switch current data, experimental data and environmental information data by simultaneously transmitting the switch current data, experimental data and environmental information data to the Internet of Things platform 50. The Internet of Things platform 50 can provide more accurate support for instrument allocation, duplicate checking and review, and performance evaluation of instrument users and expert reviewers.

[0064] Firewalls, intrusion detection systems (IDS) and intrusion prevention systems (IPS) are set between the edge gateway 40 and the IoT platform 50, and between the general gateway and the IoT platform 50 to ensure the security of data transmission. These security facilities help prevent potential network attacks and data leakage risks, and ensure the confidentiality and integrity of data.

[0065] In general, through a complete data transmission and security mechanism, experimental data and environmental information data can be effectively managed, and reliable support and guarantee can be provided for instrument use and evaluation. Such a system architecture can not only improve work efficiency, but also strengthen data security and protection measures, providing a more stable and reliable foundation for scientific research experiments and evaluation work.
