Description

Technical Field

[0001] This utility model relates to the field of prison tool management technology, and in particular to a vehicle-mounted tool management terminal. Background Technology

[0002] Tools are utensils used in production and maintenance. Under normal circumstances where tool management is not required, tools are often scattered and stored in toolboxes after use, requiring a search for them the next time, causing significant inconvenience. However, in areas requiring strict tool management, such as prisons, drug rehabilitation centers, and detention centers where offenders undergo labor reform, the use of tools needs rigorous control. Currently, tools are managed by police officers who count and distribute them to offenders when needed, recording relevant information. After use, tools are collected, counted, and recorded again. This management method is extremely inefficient. Furthermore, while the work area is monitored by police officers and surveillance cameras, the tools remain uncontrolled in the hands of offenders, posing a risk of them using them for illegal activities, and the tools may escape control.

The use of directional terms is for better and clearer explanation and understanding of this utility model, and is not intended to indicate or imply any necessary orientation of this utility model; therefore, they should not be construed as limitations on this utility model.

[0019] Examples of embodiments of this utility model Figures 1 to 2As shown, a vehicle-mounted tool management terminal includes a frame 1 with wheels at the bottom. The frame 1 is an open-fronted frame consisting of a base plate, two side plates, a back plate, and a top plate. The frame 1 is made of metal. The wheels are installed at the four corners of the bottom surface of the base plate. The wheels are swivel casters, at least one of which is a swivel caster with a braking function. A handle is also provided on the frame 1 to facilitate the movement of the management terminal. When the frame 1 has multiple drawers, it also includes a frame partition between adjacent drawers. The back plate of the frame 1 has a mesh structure, and the mesh openings form the heat dissipation holes of the frame. One or more first drawers 2 are provided on the frame 1. The first drawer 2 is mounted on the frame 1 via a slide rail (not shown in the figure). The installation of the slide rail between them is existing technology and will not be described in detail here. The first drawer 2 consists of a drawer front panel, two drawer side panels, a drawer bottom panel, and a drawer back panel, which are also made of metal. A handle is also provided on the drawer front panel for pulling the drawer. At the same time, the frame 1 is also provided with a storage cabinet 13 or a second drawer. The storage cabinet 13 or the second drawer is provided with a second electronic lock (not shown in the figure) that is electrically connected to the main control box 8. The storage cabinet 13 or the second drawer is used to store some non-tool auxiliary supplies needed in the prison work area, or it can also be used to install the management terminal. The power module 10 used at the end; for example, a storage cabinet 13 is set at the lower part of the frame 1, and then two first drawers 2 are set on top of the storage cabinet 13 in sequence; each first drawer 2 is equipped with an RFID reader 3 with multiple antennas and multiple retractable steel wire ropes 4. That is to say, each first drawer 2 is equipped with an RFID reader 3. The antenna of the RFID reader 3 is an ultra-high frequency RFID antenna and adopts a multi-layer structure. At this time, the RFID antenna is laid on the inner bottom surface of the first drawer 2. The size of the RFID antenna is matched with the inner bottom surface of the first drawer 2 or covers 4 / 5 of the inner bottom surface of the first drawer 2. In this way, After placing the tool 5 into the first drawer 2, the information of the tool 5 can be read and written more accurately. The steel wire rope 4 is set on the back panel of the first drawer 2 and is spaced along the left and right directions. Each steel wire rope 4 is retractable. The number of steel wire ropes 4 is set according to the size of the first drawer 2 and the number of tools 5 to be placed. The length of the steel wire rope 4 can be set according to the distance between adjacent work positions of labor reform personnel in the prison. For example, if the distance between two adjacent work positions is 1m, then the length of the tool 5 and steel wire rope 4 pulled out from the first drawer 2 will be less than 1m. This prevents labor reform personnel from using tools to attack personnel at adjacent work positions.Each first drawer 2 has multiple panel notches 20 arranged at intervals on the top of its drawer panel, corresponding to the steel wire ropes 4 inside the first drawer 2 and allowing the steel wire ropes 4 to pass through. The panel notches 20 are located at the top of the drawer panel of the first drawer 2, spaced apart in the left-right direction. The number of panel notches 20 corresponds to the number of steel wire ropes 4 inside the first drawer 2. The panel notches 20 are U-shaped, facilitating processing and the insertion of the steel wire ropes 4. In use, the steel wire rope 4 is first pulled out of the first drawer 2 and then inserted into the panel notch 20. Each steel wire rope 4 is fixedly connected to a tool 5, ensuring that the tool 5 can only be used within a limited area and cannot escape the control of the management terminal. When the steel wire rope 4 is retracted, the tool 5 is stored in the first drawer 2. The inner bottom surface of the first drawer 2 is provided with a protective pad 12 to prevent the tool 5 from damaging the antenna of the RFID reader 3 inside the first drawer 2 when it is being removed or placed. Each tool 5 is embedded with a metal RFID tag (not shown in the figure). Any existing embedding method can be used to embed the metal RFID tag into the tool 5. The metal RFID tag effectively prevents signal interference. Each metal RFID tag on the tool 5 is a unique identification tag corresponding to that tool 5. Embedding the metal RFID tag in the tool 5 also prevents labor reform personnel in detention centers from damaging the RFID tag to hide the tool 5 for illegal activities. Each first drawer 2 is also equipped with a first electronic lock 6, one first electronic lock 6 corresponds to one first drawer 2, and the first electronic lock 6 controls the opening or closing of the first drawer 2. The frame 1 is also equipped with multiple different identification mechanisms 7 for sequentially identifying the identities of management personnel and users, a main control box 8, and a supply... The power supply module 10 and alarm mechanism 9 are equipped with different identification mechanisms 7, which correspond to the identification of management personnel (police officers) or labor reform personnel in the prison. The identification mechanism 7 includes a card reader 70 or password input mechanism for identifying the management personnel, a fingerprint recognition mechanism and / or a face recognition mechanism 71 for identifying management personnel and labor reform personnel. The card reader 70 is a card reader, the password input mechanism is a password input keyboard, the fingerprint recognition mechanism is a fingerprint reader, and the face recognition mechanism 71 uses a face recognition camera to identify facial features. The face recognition camera is a binocular camera, which is pivotally connected to the frame 1 to adjust the angle of the camera. The pivotal structure is that the binocular camera is mounted on a damping shaft, which is mounted on the frame 1.In use, the identification mechanism 7 is activated sequentially. First, the administrator uses the card authorized by the prison to read the card information on the card reader or enters the authorized password on the password input mechanism. The identification of the administrator serves as the key to start the management terminal. After successful authentication, the management terminal is turned on. The administrator then undergoes secondary authentication through the fingerprint or facial recognition mechanism 7 before operating the management terminal. After that, the identification of the labor reform personnel is verified. The main control box 8 includes a main control chip that processes various information and controls the operation of various components, and a storage module that stores various data. The power module 10 is a rechargeable battery installed on the frame 1. The device also features various electrical connection interfaces, such as a USB port, a socket for connecting a 12V emergency external power supply, and a socket for connecting a standard 220V power supply. The alarm mechanism 9 is an audible and visual alarm device mounted on the frame 1. The sound is emitted by a speaker mounted on the frame 1, and the light comes from LEDs on the frame 1 that emit different colors of light. The alarm mechanism 9 is located on the top surface of the top plate of the frame 1. The main control box 8 is electrically connected to the RFID reader 3, the first electronic lock 2, the identification mechanism 7, and the alarm mechanism 9. The RFID reader 3 reads the information from the metal RFID tags on the tools 5 placed in the first drawer 2 and transmits it to the main control box. 8. The main control box 8 determines the status of each tool 5 as being in use or unused based on the received information. The main control box 8 controls the operation of the management terminal based on the identity information identified by the identity recognition mechanism 7. When the main control box 8 receives the first identity authentication information of the management personnel, it compares it with preset information to determine if the person is a prison management personnel. If not, it locks the management terminal and activates the alarm mechanism 9. If so, it starts the operation of the management terminal and performs a second authentication for the management personnel. If the second authentication fails, it activates the alarm mechanism 9. If the second authentication succeeds, the management personnel can control the management terminal. Then, the management terminal can be used for labor reform... The labor reform personnel undergo identity verification. Upon successful verification, the main control box 8 unlocks the first electronic lock 6 on the first drawer 2 containing the tools 5 needed by the labor reform personnel. The labor reform personnel pulls open the first drawer 2 and removes the tools 5. After removing the tools 5, the steel wire rope 4 connecting the tools 5 is inserted into the notch 20 on the panel of the first drawer 2, and the first drawer 2 is closed. The first electronic lock 6 is then locked. The main control box 8 records and saves the labor reform personnel's information and simultaneously times the removal of the tools 5. If the usage time exceeds the specified limit and the main control box 8 does not receive information about the tools 5 from the RFID reader 3, the alarm mechanism 9 is activated.

[0020] Further improvements, such as Figure 2As shown, the back panel of the first drawer 2 is provided with a receiving cavity 21. One way is to set the back panel of the drawer as a drawer back panel with the receiving cavity 21 inside. Another way is to set a drawer partition near the back panel of the first drawer 2. The drawer partition, the back panel of the drawer, and the rear of the drawer side panel form the receiving cavity. The wire rope 4 is set in the receiving cavity 21 through a spring rewinder 40. In this way, the wire rope 4 is hidden in the receiving cavity 21 to prevent the labor reform personnel from damaging it after opening the first drawer 2. The spring rewinder 40 can adopt any existing spring rewinder 40 structure. For example, the spring rewinder 40 includes a housing, a reel, and a torsion spring. The reel is rotatably set in the housing. The wire rope 4 is wound on the reel. One end of the torsion spring is fixed to the reel and the other end is fixed to the housing. The housing is provided with a through hole to guide the wire rope 4 in and out. A stop is set at one end of the wire rope 4 outside the through hole. A through hole is provided on the front wall of the cavity 21, through which one end of the wire rope 4 passes and connects to the tool 5. To prevent the tool 5 from being illegally taken, an electromagnetic brake is provided on the spring rewinder 40. The electromagnetic brake is a normally closed type. After the labor reform personnel are certified, the electromagnetic brake on the tool 5 that they can take is unlocked, and the wire rope 4 can be pulled out. The installation structure of the electromagnetic brake on the spring rewinder 40 is simply to install the electromagnetic brake on the rewinder 40. Installing the electromagnetic brake on the rewinder, i.e., the shaft, is existing technology and will not be described in detail here. At the same time, the electromagnetic brake is electrically connected to the main control box 8. When the labor reform personnel are allowed to take a certain tool 5, the main control box 8 unlocks the electromagnetic brake corresponding to that tool 5, so that the wire rope 4 can be pulled. Conversely, the electromagnetic brake is locked, and the wire rope 4 cannot be pulled.

[0021] Further improvements, such as Figure 1 and Figure 2 As shown, the main control box 8 is equipped with a display module 11, which is a touch screen on the main control box 8. Labor reform personnel can select the required tools 5 through the touch screen, and at the same time, the status of each tool in the management terminal can be displayed in real time through the touch screen, which is convenient for management personnel to control.

[0022] Further improvements include a wired and / or wireless communication module in the main control box 8. This module enables the real-time information from the management terminal to be transmitted to the prison's management platform, facilitating overall prison management. Other improvements include wireless communication modules such as Wi-Fi and Bluetooth.

[0023] Further improvements, such as Figure 2As shown, a magnetic proximity switch 14 electrically connected to the main control box 8 is installed on the frame 1. The main control box 8 is equipped with a relay that controls the power supply between the magnetic proximity switch 14 and the alarm mechanism 9. The magnetic proximity switch 14 is a normally closed type, and the relay is installed in the circuit between the magnetic proximity switch 14 and the alarm mechanism 9. In this way, a magnet compatible with the magnetic proximity switch 14 is installed at a fixed position in the detention center. When the management terminal is not in use, it is confined to a fixed position, and an alarm is triggered when it is moved illegally. After the management personnel are authenticated, the main control box 8 disconnects the electrical connection between the magnetic proximity switch 14 and the alarm mechanism 9 through the relay, so that the management terminal can be pushed from the fixed position to the workstation of the tool to be used.

[0024] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
