Description

Technical Field

[0001] This invention relates to the technical field of monitoring the working status of instruments and equipment, and more specifically, to a method and system for monitoring the working status of equipment. Background Technology

[0002] In various experimental settings, monitoring the operational status of instruments and equipment is a key aspect of management. Effective status monitoring helps managers understand the actual usage of equipment, calculate equipment utilization efficiency, optimize resource allocation, and provide data support for management decisions.

[0003] Traditional equipment condition monitoring methods typically rely on physical sensors to determine whether the equipment is operating by collecting signals such as voltage, current, vibration, and temperature. However, such methods have the following drawbacks: Modifying or adding sensors to existing equipment is costly and time-consuming. For various experimental sites, adding sensors to every piece of equipment is not economically viable, and subsequent upgrades require further modifications, making it unsustainable. Sensors themselves require maintenance; as the number of devices increases, sensor failures become more frequent, posing challenges to the long-term stability of equipment status monitoring. Mass deployment is difficult, especially with older equipment exhibiting poor compatibility. For older equipment, due to aging, lack of maintenance, and low usage frequency, sensor retrofitting and deployment are extremely challenging. Summary of the Invention

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] To address the shortcomings of existing methods for monitoring instruments and equipment in experimental settings, this invention provides a low-cost, easily deployable, and non-invasive method for monitoring equipment operational status. This method achieves convenient monitoring and recording of equipment operational status through software, requiring no additional hardware sensors or physical modifications to the equipment. Specifically, this equipment operational status monitoring method is based on a LIMS (Laboratory Information Management System).

[0019] In a preferred embodiment, such as Figure 1 As shown, the method for monitoring the working status of this device includes the following steps: Step S10: Scan the device's coded label using the mobile terminal 100.

[0020] Optionally, in this embodiment of the invention, the mobile terminal 100 is a LIMS mobile terminal 100. By scanning an coded label affixed to the device using the mobile terminal 100, the device's identifier can be collected. The coded label is a QR code.

[0021] Step S20: The mobile terminal 100 parses the encoded tag to obtain the device identifier.

[0022] Optionally, in this embodiment of the invention, the identifier is generated by combining a GUID, a registration timestamp, and a random number. A GUID (Global Unique Identifier) ​​indicates global uniqueness. By using a combination of a GUID, a registration timestamp, and a random number to generate the device identifier, its global uniqueness can be ensured.

[0023] Step S30: Mobile terminal 100 sends the identifier to server 200.

[0024] Step S40: Server 200 identifies the device based on the identifier and returns the current status of the device and the executable operations to mobile terminal 100.

[0025] Optionally, in this embodiment of the invention, the server 200 is a server 200 deployed on a LIMS platform. The server 200 can identify the device through an identifier, obtain the device's current status and executable operations, and return the device's current status and executable operations to the mobile terminal 100 to inform the operator.

[0026] Step S50: The mobile terminal 100 outputs and displays the current status of the device and the operations that can be performed.

[0027] Step S60: Send a status operation or query request through the mobile terminal 100.

[0028] Optionally, in this embodiment of the invention, the status operation includes any one of the following: power-on operation, power-off operation, fault reporting operation, or maintenance reporting operation.

[0029] Step S70: Server 200 changes the working status of the device according to the status operation; or Server 200 generates a usage report and statistical charts of the device according to the query request.

[0030] Optionally, in this embodiment of the invention, the device's operating state includes multiple operating states; these multiple operating states include: idle state, occupied state, fault state, and maintenance state; among these multiple operating states, there are constraint transition conditions between each state. The constraint transition conditions include: a state update mechanism and a conflict resolution mechanism; the state update mechanism records the change timestamp each time a state is updated; the conflict resolution mechanism uses the latest timestamp acquisition strategy as the basic method for conflict resolution and combines it with a user permission merging strategy. Figure 2 The constraints for the transition of the device's operating state are shown.

[0031] This invention ensures the atomicity and consistency of state changes by setting constraint transformation conditions. The state update mechanism and conflict resolution mechanism can be implemented through transactional data management and version control mechanisms. By employing a state update mechanism, a change timestamp is recorded with each state update. When the system receives a state update request, it is executed uniformly on the server. This mechanism prevents the concurrency problem of old data overwriting new data, ensuring that the data is always up-to-date. Simultaneously, the system uses a latest timestamp winning strategy as the basic conflict resolution scheme, combined with a user permission merging strategy, to ensure that the intent of the state change is correctly understood and executed. Furthermore, this invention also sets up an asynchronous state synchronization mechanism. This mechanism utilizes asynchronous replication to synchronize device states across different nodes, which can be implemented through transaction logs and operation pipeline technology, ensuring eventual consistency across all nodes.

[0032] Optionally, in this embodiment of the invention, the server 200 changes the working state of the device according to the status operation, including: if the status operation is a power-on operation, the server 200 records the power-on date, power-on time, power-on operator, detection items, and analysis batch, and updates the device's working state to an occupied state. If the status operation is a power-off operation, the server 200 automatically verifies whether the power-off operator is the same as the power-on operator. If so, the server updates the device's working state to an idle state and records the power-off date and time; if not, the verification fails and a prompt message is output. By performing operator authentication during the power-off operation, it can be ensured that only the current device user can perform the power-off operation, avoiding accidental power-off operations. If the status operation is a fault reporting operation, the mobile terminal 100 sends fault information to the server 200. The server 200 updates the device's working state to a fault state according to the fault information and outputs a fault notification message. After the fault is resolved, the server updates the device's working state to an idle state according to the update operation of the device administrator. If the status operation is a maintenance reporting operation, the maintenance information is sent to the server 200 through the mobile terminal 100. The server 200 updates the working status of the device to the maintenance status and outputs a notification message. After the maintenance is completed, the working status of the device is updated to the idle status according to the update operation of the device administrator.

[0033] In this embodiment of the invention, the usage reports and statistical charts can be reports generated according to multiple dimensions such as date and time, equipment, and operator. These usage reports and statistical charts include, but are not limited to, equipment usage reports, equipment utilization rate reports, and equipment failure statistics reports.

[0034] Furthermore, in this embodiment of the invention, before scanning the device's coded label via the mobile terminal 100, the following steps are performed: obtaining basic device information; pre-storing the basic information in the server 200; generating an identifier based on the basic information and printing the coded label; and affixing the coded label to the device. The basic device information includes, but is not limited to, device name, specifications, serial number, storage location, device type, and device status.

[0035] refer to Figure 3 , Figure 3 A logic block diagram of the equipment operating status monitoring system provided by the present invention is shown.

[0036] Specifically, such as Figure 3 As shown, the device operating status monitoring system includes a mobile terminal 100 and a server 200. The mobile terminal 100 includes a status acquisition module 101. The server 200 includes a device management module 201, a status processing module 202, and a data analysis module 203. Specifically, the status acquisition module 101 identifies the device's coded tag and sends status operation or query requests to the server 200; the device management module 201 maintains the device's basic information and generates the device's identifier and coded tag; the status processing module 202 verifies operation permissions, changes the device's operating status, and records operation logs; and the data analysis module 203 statistically analyzes the device's usage and generates usage reports and statistical charts.

[0037] Specifically, the specific coordination and operation process between the various units in the equipment operating status monitoring system can be referred to the equipment operating status monitoring method described above, and will not be repeated here.

[0038] Specifically, such as Figure 4As shown, firstly, log in to the LIMS platform and enter the equipment management module 201 to perform equipment registration (i.e., enter the basic information of the equipment). Specifically, the asset owner selects the instruments and equipment under their name and maintains them in the corresponding company organization. For laboratory equipment, select the corresponding laboratory; for non-laboratory equipment, select the public organization. During equipment registration, simultaneously maintain the basic information of the equipment in the LIMS system, including but not limited to: equipment name, specifications, serial number, storage location, equipment type, and equipment status. Secondly, print the equipment code label. After the asset owner maintains the instruments and equipment under their name, the LIMS system automatically generates a unique identifier for the equipment code. Print the equipment code label and affix it to a prominent location on the equipment. Next, the mobile terminal 100 performs a scanning operation. When using the equipment, the user opens the LIMS mobile terminal 100, scans the equipment's code label, clicks the power-on button, fills in the operation reason, and the LIMS server 200 automatically changes the equipment's working status to "occupied" in the background and records the equipment's power-on time, the operator, and the operation reason. When a device is shut down, the user scans the device's identification tag using the LIMS mobile terminal 100 and clicks the shutdown button. The LIMS server 200 automatically changes the device's operating status to "idle" in the background and records the shutdown time, operator, and reason for the operation. Based on the shutdown and startup times, the server 200 automatically calculates the device's operating time. When a device malfunctions, the user scans the device's identification tag using the LIMS mobile terminal 100, clicks the fault report button, and fills in the fault reason. The LIMS server 200 automatically changes the device's operating status to "malfunction" in the background and records the fault time, operator, and reason for the operation. During device maintenance, the device administrator sets the device status to "maintenance" in the LIMS device management module 201, fills in the maintenance reason, and the server 200 automatically changes the device's operating status to "maintenance" in the background and records the maintenance time, operator, and reason for the operation. Finally, the system automatically generates device usage reports, device utilization rate reports, and device fault statistics reports, providing a basis for device scheduling and maintenance planning, and optimizing resource allocation.

[0039] The logic for determining the uniqueness of equipment operating status can be referenced. Figure 5 Specifically, such as Figure 5 As shown, mobile terminal 100 scans the QR code on the device to obtain the device's coded label and parses it to obtain the device's unique identifier. Server 200 matches the device's unique identifier with pre-stored device baseline information. If they do not match, a distributed lock is executed and an error message is returned; if they match, an update operation is performed based on the status operation sent by the user through mobile terminal 100, and the timestamp is updated to complete the persistent status update and the device's status change operation.

[0040] The following is an illustration using a specific example.

[0041] This invention was deployed in a laboratory environment. First, basic equipment information was entered into the equipment management module 201 of the LIMS platform. This basic information includes, but is not limited to: equipment name, specifications, serial number, asset number, responsible person, responsible department, storage location, equipment code, equipment type, and equipment status. The system generates a QR code label for each piece of equipment, which is then affixed to a prominent location on the equipment.

[0042] Before using the equipment, scan the device's QR code label using the LIMS mobile app. The system identifies the device based on the identifier and displays its current status and available operations. Clicking "Power On" records the power-on date, time, operator, detection items, analysis batch, and other information, and updates the status to "Occupied".

[0043] After use, scan the device's QR code label and click "Power Off." The system will automatically verify if the operator is the person who powered on the device. If so, the status will be changed to "Idle," and the power-off date and time will be recorded. If not, a message will appear saying "Please contact XX for operation," and the system verification will fail.

[0044] If the equipment malfunctions, you can submit the fault information through the "Fault Report" button. The system will then change the equipment status to "Fault" and notify the equipment administrator. After the fault is resolved, the equipment administrator must update the equipment status to "Idle".

[0045] If the equipment requires maintenance, you can submit maintenance information through the "Equipment Maintenance" button. The system will then change the equipment status to "Maintenance" and notify the equipment administrator. After maintenance is completed, the equipment administrator must update the equipment status to "Idle".

[0046] The system automatically generates equipment usage reports, equipment utilization rate reports, and equipment failure statistics reports, providing a basis for equipment scheduling and maintenance plans and optimizing resource allocation.

[0047] This invention enables electronic and contactless data collection of device status without requiring hardware modifications; it suffices only by establishing a device ledger and assigning and scanning codes. This low-cost, rapid deployment of core technologies addresses a key industry pain point.

[0048] This invention fully meets the needs of equipment operating status monitoring, allowing users to view real-time equipment operating status information at any time. Simply select the corresponding equipment to view its current operating status, historical operating status, work content, operator, and other information. It also supports generating reports on the equipment's usage over any time period, ensuring online monitoring of equipment.

[0049] This invention combines device operation with identity verification to ensure the authenticity and traceability of operation records; device operation is automatically linked to the operator, effectively preventing data tampering and ensuring the authenticity and traceability of every record. This enhances the effectiveness and persuasiveness of device management. It also possesses good scalability and can be adapted to various types of experimental equipment and management scenarios.

[0050] This invention supports applications across multiple scenarios, from small experimental tools to large experimental benches. Real-time monitoring of equipment operating status can be achieved simply by maintaining equipment information in the equipment ledger. It accurately records user and task information, facilitating refined management and accountability. Equipment usage reports include user, date, time, duration, reason for use, and related test analysis items, completely replacing manual record-keeping and significantly reducing error rates. It supports in-depth data analysis and decision support, such as comparative classification of equipment operation, equipment load for various projects, failure rates of different types of equipment, user information, equipment efficiency ratios for different projects, and equipment idle / shortage status, thereby improving the level of lean equipment management.

[0051] This invention is applicable to various occasions that require refined management of equipment operating status, and has high practical value and promising prospects for promotion.
