Description

Technical Field

[0001] The present invention relates to the technical field of electric control cabinets, and in particular to a tablet computer control cabinet. Background Art

[0002] A control cabinet is a cabinet used to store electronic equipment. While its structure can be achieved using existing technologies, different cabinets may employ different control methods due to their varying functions. Some manufacturing companies often use tablet computers for production control. This involves pre-installing production management software on the tablet, entering relevant production parameters, and controlling the smart devices on the production line. To ensure traceability, the production parameters entered by employees need to be uploaded to a cloud platform or business management platform for storage, allowing backend management systems to access the data.

[0003] Furthermore, to ensure confidentiality, the business data generated by the tablet's production management software, known as business data, cannot be directly sent to the cloud platform or business management platform over a wireless network. Instead, it must be uploaded via a wired network. To upload this data to the business management platform, a control cabinet is required to house the tablet and connect it to a data cable for wired data transmission.

[0004] Placing a tablet in a control cabinet requires not only data transmission but also charging. Therefore, existing control cabinets often use a single data cable for both charging and data transmission. However, for confidentiality and security reasons, the cabinet's electronic lock must be managed. Existing control cabinets are controlled via a cloud platform, specifically the electronic lock within the cabinet. This means that both the cabinet's control data and business data are transmitted over the same data cable, compromising confidentiality. Summary of the Invention

[0005] The purpose of the present invention is to provide a tablet computer control cabinet that can solve the following technical problems:

[0006] (1) The control signals of the control cabinet and the business data uploaded by the tablet are uploaded to the cloud platform or business management platform through the same data cable. The signals between the business data and the control signals of the control cabinet are isolated by software, and the confidentiality level is low. The cabinet of the control cabinet cannot be locally controlled.

[0007] (2) The door opening strategy of the control cabinet is random and does not take into account the user's height, resulting in a poor user experience. At the same time, the frequency of tablet computer use is controlled and the use of tablet computers cannot be balanced.

[0051] Figure 2 This is a block diagram of a cabinet control system according to one embodiment of the present invention;

[0052] Figure 3 This is a data flow diagram for the business management platform and the control platform in one embodiment of the present invention.

[0054] The present invention provides a tablet computer control cabinet, comprising a main cabinet 1 and a cabinet control system. The main cabinet provides a storage space for tablet computers. The main cabinet can be assembled using conventional methods using panels, etc. The electronic devices or smart devices installed in the main cabinet are primarily controlled by the cabinet control system.

[0055] The main cabinet is equipped with several storage cabinets 2, each equipped with an electronic lock. The electronic locks communicate with the cabinet controller, which controls their opening. Each cabinet can accommodate a tablet computer and comes with a data cable. Most of the main cabinet space is dedicated to storage cabinets, allowing for the installation of more cabinets. The remaining space is used for electronic equipment, communication equipment, and auxiliary wiring structures.

[0056] The storage cabinet contains a tablet computer data cable, which is connected to an adapter. The adapter is connected to a charging data cable and a network data cable. The tablet computer data cable itself can directly connect to the tablet computer. Existing data cables already perform both data transmission and charging functions, so the tablet computer data cable of the present invention can also perform both charging and data transmission functions.

[0057] Business data is pre-stored in the tablet computer. The business data is generated by the relevant software system when the user uses the tablet computer. After the tablet computer is connected to the network, the corresponding software system can upload the business data to the business management platform. The business data can be uploaded manually by the user operating the tablet computer or automatically by the corresponding software system. The software system and its functions on the tablet computer are existing technologies and do not belong to the invention of this invention.

[0058] The tablet computer data cable is used to connect to the tablet computer, charging it and obtaining its device information and business data. The charging data cable is used to deliver power and upload the tablet computer's device information and the adapter's MAC address to the management and control platform via the communication unit. Device information includes the device's IP address, remaining battery life, and usage time. The network data cable is used to upload business data stored on the tablet computer to the business management platform via the communication unit. The management and control platform and the business management platform are independent platforms. The management and control platform is primarily used for cabinet control and data aggregation, enabling remote control and data storage.

[0059] As can be seen from the background technology, the data that the tablet computer of the present invention needs to output is divided into two categories. One category is business data, which needs to be transmitted to the business management platform via a wired network, thereby facilitating the administrator of the business management platform to view and use relevant business data. The other category is the tablet computer's device information, including the device IP address, remaining battery power, and usage time. This data does not need to be uploaded to the business management platform, but it needs to be transmitted to the cabinet controller so that the cabinet control system can understand the relevant information and implement intelligent control of the cabinet.

[0060] Furthermore, because the tablet's placement isn't fixed, the cabinet control system can't determine which cabinet it's installed in based on the tablet's device information. To overcome this problem, the present invention incorporates an adapter that physically isolates the tablet's charging data cable from the network data cable required for uploading service data, isolating the two during signal transmission. The adapter also carries a built-in MAC address, which can be used to match the tablet to the cabinet. This means the correspondence between the adapter and the cabinet is fixed and unchanging. This technical solution offers the following advantages: once a tablet is stored in a cabinet, it can upload data through the adapter. Both the service management platform and the cabinet control system can determine the tablet's exact placement, i.e., the cabinet in which it was placed, allowing them to open the corresponding cabinet when needed. For example, when a tablet needs to be retrieved, the cabinet control system can determine which adapter it's connected to. Because the correspondence between the adapter and the cabinet is pre-set, the tablet can be quickly and accurately located using the adapter.

[0061] The cabinet of the present invention is primarily controlled by a cabinet control system, which includes a cabinet controller, an authentication and entry unit 4 connected to the cabinet controller, a heat dissipation unit, a fire control unit, and a communication unit. The authentication and entry unit is used to enter user authentication information and input user commands. The authentication and entry unit may include electronic devices capable of information entry and identity authentication, such as a keyboard, a camera, a touch screen, and a fingerprint entry device. Such electronic devices are already known in the art for authentication and entry units.

[0062] The heat dissipation unit dissipates heat within the control cabinet. It includes a fan 3, a motor, a motor controller, and a temperature sensor. The temperature sensor transmits temperature information to the cabinet controller, which controls the motor's operating status, and thus the fan's operating status. The fire control unit detects fires and includes a smoke sensor and an alarm. The smoke sensor transmits smoke signals to the cabinet controller, which controls the alarm's operating status. Both the heat dissipation unit and the fire control unit are designed to ensure the safe and stable electrical operation of the control cabinet and prevent accidents.

[0063] When the control cabinet of the present invention is in use, the cabinet controller receives information from the authentication input unit, determines the user's current request, and controls the locking state of the electronic lock according to the user's request after the verification is passed. Before using the control cabinet, ordinary users need to pre-enter the user's authentication information so that the user can obtain relevant permissions. The requests of ordinary users are mainly to store tablet computers and to take tablet computers. The management user can include the authority to open and close any storage cabinet, and can also modify the authority and authentication information of ordinary users. The users of the present invention mainly refer to ordinary users, that is, people who need to use the control cabinet to store and take tablet computers.

[0064] When a user enters information requesting to store a tablet, the number of tablets the user has stored (X) is collected, and X recommended charging cabinets are opened, with each tablet placed in a separate cabinet. When a user enters information requesting to remove a tablet, the number of tablets the user has removed (X) is collected, and X recommended removal cabinets are opened.

[0065] In one embodiment of the present invention, the user's authentication information includes user name, user number, user position, and fingerprint information and login password associated with the authentication information; this allows corresponding data to be generated in the management log of the controller system, so that the access status of each user can be known.

[0066] In one embodiment of the present invention, the communication unit is a switch, which can have multiple connectors and can realize signal transmission and conversion within the cabinet. The cabinet controller is a PLC microcontroller. A PLC microcontroller can be installed in the main cabinet and the auxiliary cabinet respectively. The PLC microcontroller in the auxiliary cabinet can transmit data to the cabinet controller of the main cabinet, and the cabinet controller of the auxiliary cabinet can control the electronic lock of the auxiliary cabinet. The main cabinet is provided with ventilation holes and wire ducts, and fans can be installed in the ventilation holes. The wire duct 5 facilitates wiring.

[0067] In one embodiment of the present invention, a main cabinet is equipped with 30 to 40 storage cabinets; a fire extinguisher device is mounted externally on the main cabinet. The control cabinet also includes multiple auxiliary cabinets, each of which contains multiple storage cabinets. Each auxiliary cabinet is equipped with a communication unit and a cabinet controller. The cabinet controller is connected to a heat dissipation unit, a fire control unit, and a communication unit. The communication unit of the auxiliary cabinet is connected to the communication unit of the main cabinet to upload data in the auxiliary cabinet to a control platform or business management platform.

[0068] In one embodiment of the present invention, when a storage cabinet is opened for storage, the presence of a tablet computer is detected when the electronic lock of the cabinet is closed again, and an alarm is issued if an abnormality is detected. When the storage cabinet is opened for retrieval, the presence of a tablet computer is detected when the electronic lock of the cabinet is closed again, and an alarm is issued if an abnormality is detected. This allows detection of whether the user has performed the corresponding operation and whether the tablet computer is stored or removed in a timely manner.

[0069] Storage cabinets in the prior art are opened randomly without considering external factors, such as the height of the user. Different users have different heights, which results in the height of the cabinet affecting the user's comfort when using the cabinet. When shorter people use taller cabinets, it is inconvenient to take things out, or they need to stand on a stool to take them out. In addition, tablet computers have a lifespan and are more susceptible to damage with frequent use. Storage cabinets in the prior art cannot recommend tablet computers in a balanced manner, and cannot ensure that the usage frequency of tablet computers is relatively close. It is easy for some tablet computers to be used more frequently and some tablet computers to be used less frequently, or the recommendations are not made based on the number of times the tablet computers are used.

[0070] In one embodiment of the present invention, the method for determining the recommended charging cabinet is:

[0071] (1) Detect whether there is a tablet computer in the storage cabinet. The tablet computer detection can be determined based on whether the tablet computer is connected to the data cable. When the tablet computer is connected to the data cable, it can be determined that a tablet computer is placed in the storage cabinet. Then, the storage cabinets without tablet computers are filtered out, and the information of the storage cabinets with empty status is obtained. The storage cabinet information includes the location number and height of the storage cabinet.

[0072] (2) A height detection device is provided on the main cabinet to obtain the height information H of the current user. The height detection device can be used for detection by means of video or image in the prior art. For example, the person in front of the main cabinet can be photographed and the height can be measured by the image obtained by the camera. This technology belongs to the prior art, such as "Method for measuring the height of a target person in a surveillance video screen" and CN202011247671.X "Height detection method and device based on image acquisition equipment".

[0073] After obtaining the height information of the human body through existing technology, the height D of the center of each storage cabinet that has been pre-entered is obtained. The height of each storage cabinet is fixed and this information can be entered after the storage cabinet is installed. The relevant information can be entered through the authentication entry unit. Finally, the height coefficient P of each empty storage cabinet is calculated:

[0074]

[0075] Where H is the height of the current user, and D is the horizontal height of each empty storage cabinet. The horizontal height refers to the height between the center of the storage cabinet and the ground.

[0076] For example, when users of different heights use the locker, the height coefficients calculated are as follows:

[0077] S(cm) L(cm) P 120 200 0.204 150 200 0.243 160 200 0.255 180 200 0.278 200 200 0.301 220 200 0.342

[0078] It can be seen from the above table that when the height L of the storage cabinet is fixed at 200 cm, the taller the user is, the more convenient it is for the user to use the storage cabinet, and the larger the value of the height coefficient is.

[0079] (3) Obtain the number of times each empty locker electronic lock is used per cabinet, Q, i.e., the number of times each locker electronic lock is opened; calculate the average number of times the empty locker electronic lock is used, W;

[0080] m is the total number of currently empty lockers.

[0081] (4) Based on the average number of times the electronic lock is used W, the total number of storage cabinets N, and the number of times the electronic lock of an empty storage cabinet is used Q, the usage coefficient K of each empty storage cabinet is obtained:

[0082]

[0083] (5) Calculate the recommended value T = P + K based on the height coefficient and the usage coefficient; sort the items based on the recommended value; detect the number of items X requested by the user, and determine the X lockers with the largest recommended values ​​as the recommended lockers for charging. Sort the recommended values ​​based on the recommended value formula. For example, if the user requests to open three lockers, that is, X = 3; then open the lockers with the top three recommended values.

[0084] In the optimized solution of the present invention, 30 to 40 storage cabinets are arranged on the main cabinet body, and 30 to 40 storage cabinets are arranged on the auxiliary cabinet body.

[0085] The recommended strategy for opening lockers during storage and charging uses the strategy described above. This strategy takes into account height and the frequency of use of electronic locks. This allows lockers with suitable heights and less frequently used electronic locks to be opened first, making the frequency of use of each locker more balanced and preventing individual locker failures due to multiple, concentrated uses.

[0086] In one embodiment of the present invention, the method for determining the recommended storage cabinet to be removed is:

[0087] (1) Detect whether there is a tablet computer in the storage cabinet and determine whether the remaining power of the tablet computer exceeds a threshold value, and determine the tablet computer to be used. If the remaining power is low, below the threshold value, it means that the tablet computer has insufficient power to work and cannot be put into use. After screening out the tablet computers that can be used, obtain the information of the storage cabinet of the tablet computer to be used, which includes the location number and height of the storage cabinet.

[0088] (2) Set up a height detection device on the main cabinet to obtain the current user's height information H; obtain the pre-entered height D of the center of each storage cabinet; calculate the height coefficient P2 of each empty storage cabinet:

[0089]

[0090] Where H is the current user's height data, and D is the horizontal height of each empty storage cabinet.

[0091] (3) Obtain the usage count Q2 of the tablet computer in each storage cabinet and calculate the average usage count W2 of the tablet computer;

[0092] n is the total number of cabinets currently storing tablet computers to be used.

[0093] (4) Based on the average number of tablet computer usage W2, the total number of storage cabinets N, and the number of times each tablet computer is used Q2, the usage coefficient K2 of each storage cabinet containing the tablet computer is obtained:

[0094]

[0095] (5) Calculate the recommended value T2 = P2 + K2 based on the height coefficient and the usage coefficient; sort according to the recommended value; detect the number X2 of unused tablet computers requested to be taken out by the user, and determine the storage cabinets with the X2 maximum recommended values ​​as the recommended storage cabinets to be taken out.

[0096] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of this patent.
