[0002] Hazardous chemicals (hereinafter referred to as "hazardous chemicals") refer to chemical substances with properties such as toxicity, corrosion, explosion, combustion and combustion-supporting properties. These substances may cause serious harm to the human body, facilities and the environment. Hazardous chemicals are widely used in laboratories of universities and scientific research institutions, but as the demand for hazardous chemicals in laboratories increases, safety hazards also increase. Therefore, the management of hazardous chemicals in laboratories has become the focus of safety control for governments, enterprises and universities.

[0003] In the field of hazardous chemicals management, traditional management methods mainly rely on manual operations, which are inefficient and prone to errors, and cannot meet the requirements of modern society for the safe management of hazardous chemicals. The introduction of RFID (radio frequency identification) technology provides a new solution for item tracking and inventory management. Although RFID readers have significant advantages in improving management efficiency and achieving automatic recording, they still face some challenges in practical applications.

[0026] In the management of hazardous chemicals, although RFID readers can identify the electronic tags on hazardous chemicals and open the corresponding cabinet doors, in actual situations, multiple types of hazardous chemicals are placed in the same storage area, which makes it difficult for users to quickly and accurately find the target hazardous chemicals when extracting the required hazardous chemicals. If you want to achieve fast and accurate extraction, the ideal way is to store the same type of hazardous chemicals separately, which undoubtedly brings inconvenience to the user and also limits the storage types and space utilization efficiency of hazardous chemicals. Therefore, the present invention aims to provide a hazardous chemical intelligent management terminal to improve the efficiency of hazardous chemicals. The following is a specific embodiment of the hazardous chemical intelligent management terminal in the present invention.

[0027] Please refer to the attached Figure 1 To Attachment Figure 4As shown, an embodiment of the present invention provides an intelligent management terminal for hazardous chemicals, including a cabinet 10, a cabinet door 20, a camera 50, an indicator light strip 60 and a server 120. A plurality of trays 101 are arranged inside the cabinet 10 to divide the cavity of the cabinet 10 into a plurality of storage cavities 102 for placing hazardous chemicals carrying label information; the cabinet door 20 is arranged one-to-one in correspondence with each storage cavity 102, and is locked to the user-facing side of the cabinet 10 by an electromagnetic lock 30, and the electromagnetic lock 30 is connected to an electromagnetic lock driving module 40; a camera 50 is installed on the top of each storage cavity 102 to collect label information and location information of hazardous chemicals; an indicator light strip 60 is arranged on each tray 101, and is connected to a light controller 70 to visually indicate the location of the target hazardous chemicals; the server 120 is connected to the camera 50 in communication to identify the label information of the target hazardous chemicals and mark the location information of the target hazardous chemicals; the server 120 is also connected to the electromagnetic lock driving module 40 and the light controller 70 in communication, and the server 120 sends an unlocking command to the electromagnetic lock driving module 40 according to the location information of the target hazardous chemicals to automatically open the corresponding cabinet door 20, and outputs a lighting command to the light controller 70 to automatically light up the indicator light strip 60 at the corresponding position.

[0028] It should be specifically explained that a plurality of trays 101 can be arranged at intervals along the height direction of the cabinet 10 to divide the cabinet 10 cavity into a plurality of storage cavities 102, and each storage cavity 102 can be used to store different types of hazardous chemicals. Among them, a plurality of trays 101 are arranged at equal intervals in the height direction of the cabinet 10 cavity. In a specific embodiment, three trays 101 are arranged in sequence from bottom to top inside the cabinet 10 cavity, and the lowest tray 101 is arranged at the bottom of the cabinet 10.

[0029] In this embodiment, a separate cabinet door 20, a camera 50 and an indicator light strip 60 are provided for each storage cavity 102, and the label information and location information of the hazardous chemicals placed in the storage cavity 102 are collected by using the camera 50. After the label information of the target hazardous chemicals is identified and the location information of the target hazardous chemicals is marked by using the server 120, an unlocking command is sent to the electromagnetic lock drive module 40 to automatically open the corresponding cabinet door 20. At the same time, the server 120 also sends a lighting command to the lighting controller 70 to automatically light up the indicator light strip 60 at the corresponding position of the target hazardous chemicals. In this way, when the user extracts the target hazardous chemicals, he can intuitively see the location of the target hazardous chemicals, so as to quickly and accurately find the required hazardous chemicals.

[0030] In some optional embodiments, the indicator light strip 60 includes a plurality of array-distributed lamp beads, and the light controller 70 independently controls the on / off state of each lamp bead. It should be further noted that the lamp beads may be, but are not limited to, white light lamp beads. Users may also select other types of lamp beads, such as colored LED lamp beads, according to their needs to achieve different visual effects.

[0031] In some optional embodiments, the server 120 includes a region identification module, which marks the location information of the target hazardous chemicals and identifies the lamp bead area corresponding to the location of the target hazardous chemicals, and the light controller 70 sends a lighting signal to the corresponding lamp bead area. It should be further explained that the region identification module stores a region mapping table, which associates the position in the storage cavity 102 with the corresponding lamp bead area. The region identification module identifies the label information and location information of the target hazardous chemicals through image processing technology, and finds the lamp bead area corresponding to the location information in the region mapping table through a search algorithm.

[0032] In some optional embodiments, the camera 50 is installed at the top center of each storage cavity 102, and the distance between the camera 50 and the corresponding tray 101 is in the range of 40cm-50cm. This can reduce the blind spot and enable it to better cover the entire storage cavity 102, thereby more accurately collecting the label information and location information of the hazardous chemicals in the storage cavity 102.

[0033] In some optional embodiments, the intelligent management terminal for hazardous chemicals also includes a fingerprint recognition module 80, which is communicatively connected to the server 120 for the user to log in for the first time through a fingerprint and to authorize a secondary login when the user accesses the target hazardous chemicals.

[0034] In some optional embodiments, the intelligent management terminal for hazardous chemicals also includes a face recognition module 90, which is communicated with the server 120 for the user's first login and authorizes a second login when the user accesses the target hazardous chemicals. In some optional embodiments, the intelligent management terminal for hazardous chemicals further includes a scanning unit 100, which is communicatively connected to a server 120 and is used to scan label information on hazardous chemicals when the hazardous chemicals are put into storage or returned.

[0035] In some optional embodiments, a vent 103 is provided in each storage cavity 102. The vent 103 can effectively discharge the gas generated by the hazardous chemicals in the storage cavity 102, thereby ensuring safety and environmental cleanliness.

[0036] It should be further explained that, in some optional embodiments, a ventilation cavity is provided on the rear side of the cabinet 10 cavity and the plurality of storage cavities 102, one end of the ventilation cavity is connected to the storage cavity 102, and the other end is connected to the outside, thereby rationally utilizing the internal space of the cabinet 10. In one embodiment, a one-way exhaust fan is configured in the ventilation cavity. The operation of the one-way exhaust fan can quickly and effectively discharge the gas generated by the volatilization of hazardous chemicals in the storage cavity 102 to the outside of the intelligent management cabinet for hazardous chemicals. This design not only improves the ventilation effect in the cabinet 10, but also reduces the risk of accumulation of harmful gases, further enhancing the safety and reliability of the intelligent management cabinet for hazardous chemicals.

[0037] Furthermore, an installation cavity is provided on the left or right side of the cabinet 10 cavity and the multiple storage cavities 102, and the installation cavity is used to install the circuit board. This layout design effectively improves the structural compactness of the intelligent management terminal for hazardous chemicals and reduces the overall volume, thereby better adapting to the environmental requirements with limited space.

[0038] In some optional embodiments, a weight sensor is provided under the tray 101 to collect the weight information of the hazardous chemicals. Specifically, a gravity sensor 110 is installed at the central position under the tray 101, and the gravity sensor 110 is connected to the server 120 in communication. The gravity sensor 110 can measure the weight of the hazardous chemicals placed on the tray 101 in real time, so that the user can conveniently monitor the use of hazardous chemicals and grasp the inventory status in time.

[0039] In addition, please see the attached Figure 5 As shown, an embodiment of the present invention further provides a management method of a hazardous chemicals intelligent management terminal based on any one of the above embodiments, and the management method comprises the following steps: S101: Obtain user identity information, perform initial identification and authentication on the identity information, and issue access rights based on the identification and authentication results. Specifically, the user's identity information is obtained through the fingerprint recognition module 80 or the face recognition module 90. Then, the server 120 performs initial identification and authentication on the acquired identity information. After the authentication is completed, the server 120 issues access rights based on the identification and authentication results to ensure that only authorized users can access the operating system of the hazardous chemicals intelligent management device.

[0040] S102: When the user needs to take the target hazardous chemicals, the type information of the target hazardous chemicals is obtained and a take list is generated. Specifically, this process involves a database query to confirm the specific type and related attributes of the required hazardous chemicals.

[0041] S103: Perform secondary identification and authentication on the user's identity information, and issue access rights based on the secondary identification and authentication results; this process is intended to further ensure the authenticity of the user's identity and prevent unauthorized users from accessing the system. After the secondary authentication is completed, the server 120 will issue access rights again based on the authentication results.

[0042] S104: According to the access list, the camera 50 collects the label information and location information of the hazardous chemicals. After the server 120 identifies the label information of the target hazardous chemicals and the location information of the marked target hazardous chemicals in the access list, it sends an unlocking command to the electromagnetic lock drive module 40 to automatically open the corresponding cabinet door 20, and outputs a lighting command to the lighting controller 70 to automatically light up the indicator light strip 60 at the corresponding position, so that the user can intuitively see the location of the target hazardous chemicals, thereby quickly and accurately finding the required hazardous chemicals.

[0043] Please see attached Figure 6 As shown, in some optional embodiments, the management method of the hazardous chemicals intelligent management terminal further includes the following steps: S105: When the user takes out the target hazardous chemicals, outbound information is generated; the outbound information includes key information such as the name of the hazardous chemicals taken, the time of taking, the storage location and the identity of the user.

[0044] S106: Bind the outbound information with the user identity information, generate a retrieval record, and store the retrieval record in the hazardous chemicals database.

[0045] This embodiment adds steps S105 and S106, so that when users take out hazardous chemicals, the generation and binding of outbound information not only improves the transparency of management, but also enhances the monitoring and management capabilities of the use of hazardous chemicals.

[0046] Please see attached Figure 7 As shown, in some optional embodiments, the management method of the hazardous chemicals intelligent management terminal further includes the following steps: S107: When the user needs to return the target hazardous chemicals, the label information of the target hazardous chemicals is obtained through a scanner.

[0047] S108: Based on the label information of the target hazardous chemicals, the server 120 sends an unlocking command to the electromagnetic lock driving module 40 to automatically open the corresponding cabinet door 20. This step allows the user to conveniently put the returned hazardous chemicals back into the designated storage cavity 102.

[0048] S109: When the user returns the target hazardous chemicals, warehousing information is generated. The warehousing information includes the name, quantity, return time, user identity and storage location of the returned hazardous chemicals, ensuring that each warehousing operation has a basis.

[0049] S110: Bind the warehousing information with the user identity information, generate a return record, and store the return record in the hazardous chemicals database.

[0050] By adding steps S107 to S110, the management method of the intelligent management terminal for hazardous chemicals is further enhanced in the management of hazardous chemicals return. The method simplifies the user return process and improves management efficiency.
