[0011] Optionally, the specific process by which the calculation processing module determines abnormal situations is as follows: If the current data in the device status information is abnormal, it is determined to be a first-type abnormality, and a first alarm message and a corresponding first abnormality record document are generated. If the current data is normal but the voltage data is abnormal, it is determined to be a second type of abnormality, and a second alarm message and a corresponding second abnormality record document are generated. If both current and voltage data are normal, the test data information is determined based on the operating parameters set by the environmental testing equipment: If the temperature data exceeds the preset value, it is judged as a third type of anomaly, and a third alarm message and a corresponding third anomaly record document are generated.

Detailed Implementation

[0020] To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention 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 merely illustrative of the invention and are not intended to limit the invention.

It should be understood that such data can be used interchangeably where appropriate. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0022] Reference Figure 1 and Figure 3 This invention employs an Internet of Things-based data acquisition and control device to achieve remote management of multi-environment test equipment.

[0023] like Figure 1 As shown, this application discloses a data acquisition and control device, comprising: The data access module 100 is an access interface for industrial equipment or intelligent devices, used to connect to one or more environmental testing devices and receive equipment status information and test data information from the environmental testing devices; the equipment status information includes current and voltage; the test data information includes temperature changes over time and humidity changes over time. The data conversion and storage module 200 is used to perform protocol parsing and conversion on the received data, and to store the data and control management program. The computing and processing module 300 is used to process the stored data, generate corresponding charts, and upload them to the cloud (cloud server). It also combines the stored control and management program to retrieve the received data and issue corresponding control commands to realize a multi-experimental equipment management method.

[0024] Using the above scheme, the data acquisition and control equipment connects to the environmental testing equipment via the data access module 100, receiving equipment status information and test data. The data acquisition and control equipment uses the data conversion and storage module 200 to perform protocol parsing, conversion, and storage of the relevant data from the environmental testing equipment. The purpose is to convert the equipment's relevant data into a unified format for easy compression, storage, and processing. The converted data is sent to the calculation and processing module 300 of the data acquisition and control equipment. The calculation and processing module 300, combined with the stored management and control programs and judgment rules, analyzes and judges the equipment status information (current, voltage) and test data information (temperature, humidity) of the environmental testing equipment. Based on data anomalies, it issues corresponding alarm information to prompt personnel to handle the abnormalities, and simultaneously generates corresponding anomaly documents for subsequent traceability and maintenance.

[0025] By connecting the data access module of the data acquisition and control equipment with the environmental testing equipment in the laboratory, the relevant data information of the environmental testing equipment can be directly exported. After data parsing and transfer processing, the processed data is uploaded to the cloud, which makes it convenient for test personnel to remotely understand and manage the test process and test results. This replaces the traditional manual recording and manual on-duty, ensuring the objectivity and reliability of the data results.

[0026] Specifically, such as Figure 2 As shown, based on the equipment status information of the environmental testing equipment, determining whether the equipment has any abnormalities specifically includes the following steps: If the current data of the environmental testing equipment is abnormal, the environmental testing equipment is judged to be a Class I abnormality. If the current data of the environmental testing equipment is not abnormal, then determine whether the voltage data of the environmental testing equipment is abnormal; If the voltage data of the environmental testing equipment is abnormal, the environmental testing equipment is judged to be a type II abnormality. If there is no voltage abnormality in the environmental testing equipment, then it is determined that there is no abnormality in the environmental testing equipment.

[0027] The above technical solution determines whether there is an abnormality in the environmental testing equipment based on the equipment's status information. If an abnormality is found, the system combines the automatically generated abnormality records to query the type of abnormality, facilitating subsequent maintenance and traceability of equipment abnormalities, and improving the reliability of equipment operation and management.

[0028] Based on the test data from the environmental testing equipment, determining whether the equipment has any functional abnormalities includes the following steps: If the equipment status information is normal, then based on the operating status parameters set for the environmental testing equipment, determine whether the operating environmental testing equipment has any operating status parameters that do not conform to the preset standard parameters: If the temperature data of the environmental testing equipment exceeds the preset value, there is a temperature anomaly, and the environmental testing equipment is judged to be a third type of anomaly. If the environmental testing equipment does not exhibit temperature anomalies, then determine whether the humidity data of the environmental testing equipment exhibits humidity anomalies. If the humidity information of the environmental testing equipment exceeds the preset value, the environmental testing equipment is judged to be a Class IV anomaly. If the environmental testing equipment does not exhibit abnormal humidity, then it is determined that the environmental testing equipment does not have any functional abnormalities.

[0029] By employing the aforementioned judgment logic scheme, test data information is obtained based on equipment information to determine whether the test data during the operation of the environmental testing equipment exceeds a set threshold. If so, it is determined that the production equipment has a functional abnormality, facilitating subsequent tracing of test results and equipment failures.

[0030] Based on the above-mentioned abnormal situations, corresponding alarm information and related log documents are generated to prompt staff to handle the relevant abnormal situations. The specific steps include the following: When the abnormal situation is the first type of abnormality, a relevant record document is generated and a first alarm message is sent. When the abnormal situation is the second type of abnormality, a relevant record document is generated and a second alarm message is sent; When the abnormal situation is the third type of abnormality, a relevant record document is generated and a third alarm message is sent; When the abnormal situation is the fourth type of abnormality, a relevant record document is generated and a fourth alarm message is sent.

[0031] The above logic scheme determines the type of abnormality and obtains and sends corresponding alarm information based on different abnormalities, so that staff can take different measures to deal with the environmental testing equipment accordingly.

[0032] Furthermore, such as Figure 3 As shown, this application also provides a method for managing multiple experimental devices based on data acquisition and control equipment, including the following steps: Step S1: Obtain equipment information for one or more environmental testing devices.

[0033] Step S2: Obtain records of the equipment status information during the operation of the environmental testing equipment and generate relevant charts. The equipment status information includes usage information (equipment user), operating status, operating time, current, and voltage. Based on the equipment status information of the environmental testing equipment, determine whether there is any abnormality in the equipment. If there is an abnormality, proceed to step S3; otherwise, proceed to step S4.

[0034] Step S3: Generate alarm information and corresponding record documents, prompting staff to handle the abnormal situation, and then proceed to step S6.

[0035] Step S4: Obtain the recorded test data information during the operation of the environmental testing equipment and form relevant charts. The test data information includes the temperature change value and the humidity change value over time. Based on the test data information of the environmental testing equipment, determine whether there is any abnormality in the test process. If there is an abnormality, proceed to step S5 and then to step S6. Otherwise, proceed directly to step S6.

[0036] Step S5: Generate alarm information and corresponding record documents to prompt staff to handle the abnormal situation.

[0037] Step S6: Upload the relevant information of the above environmental testing equipment to the cloud.

[0038] Step S7: Access the cloud via a remote terminal (mobile phone or PC) to obtain information display and achieve remote monitoring.

[0039] The above technical solution simultaneously acquires equipment information, equipment status information, and test process data from multiple operating environmental testing devices. Specifically, the equipment status information and test process data are transmitted via the environmental test chamber's data interface to the data conversion and storage module of the data acquisition and control equipment using the MODBUS RTU protocol. The data acquisition and control equipment's computing and processing module processes the data, converts the data format, generates charts, and uploads the data to the cloud. Test personnel access the data on the cloud server through terminal devices, avoiding traditional manual monitoring and data transcription, thus ensuring the accuracy and objectivity of the test results.

[0040] Based on the obtained equipment status information and test data, and in conjunction with the test requirements, a comprehensive judgment is made to determine whether there are any abnormalities in the environmental testing equipment and its functions. If an abnormality is found, an alarm message is generated and a corresponding abnormality (alarm) record is produced, prompting staff to handle the abnormality and trace the abnormality. This achieves intelligent management of the equipment and improves the safety and reliability of the production equipment operation.

[0041] On the other hand, such as Figure 4 As shown, this application also discloses a multi-experimental equipment management system based on data acquisition and control equipment, including: The information acquisition module 400 is used to acquire equipment information, equipment status information, and test data information of one or more environmental testing devices. The information judgment module 500 is used to determine whether there are any abnormalities in the environmental testing equipment and its functions based on the equipment status information and test data information. The abnormality recording and alarm module 600 is used to automatically generate relevant information documents and issue alarm information to prompt staff to handle the abnormality when an abnormal situation occurs. The information display module 700 is used to allow test personnel to access information on the cloud server through a remote terminal after the data acquisition and control equipment uploads the collected and processed data to the cloud, so as to understand the test data information and abnormal conditions of one or more environmental test equipment and realize remote monitoring.

[0042] Through the above scheme, the information acquisition module 400 acquires equipment information, equipment status information, and test data information of the environmental testing equipment, and sends the data information to the information judgment module 500. The information judgment module 500 judges whether there are any abnormalities in the environmental testing equipment and its functions based on the received information, and sends the abnormalities to the abnormality recording and alarm module 600. The abnormality recording and alarm module 600 generates an abnormality information document based on the received abnormalities and issues an alarm to prompt staff to handle the abnormalities. The information display module 700 centrally displays the above process and related information, allowing users to understand the equipment's operating status and abnormalities from a PC or mobile device. This achieves remote monitoring of multiple environmental testing devices, realizing unattended operation, improving the management and usage efficiency of environmental testing equipment, and ensuring the objectivity and reliability of test information data.

[0043] The technical solution of the present invention has the following beneficial effects: 1) The automatic generation and display of experimental data information has replaced the traditional manual transcription, effectively ensuring the objectivity and validity of the experimental results; 2) Based on the relevant information of the environmental testing equipment, determine whether there are any abnormalities in the equipment operation. If there are any abnormalities, generate different alarm messages according to the specific abnormalities to remind staff to handle the production equipment. Combined with the abnormality record document, it is easy for production management personnel to trace the cause of the abnormality, thereby improving the safety and reliability of the production equipment. 3) The centralized display of test equipment information enables remote management of environmental test equipment, effectively improving the efficiency of environmental test equipment use.

[0044] The specific embodiments of the present invention have been described in detail above, but they are merely examples, and the present invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications and substitutions to the present invention are also within the scope of the present invention. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present invention should be covered within the scope of the present invention.
