[0018] Figure 3 A cloud system structure diagram according to an embodiment of the present invention is shown. Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] The following is for reference. Figure 1-3 Understanding the embodiments of the first aspect of this utility model.
[0021] First Embodiment: The device in this embodiment uses radio frequency identification (RFID) to identify employee or object information, and then uploads it to the DHR system to achieve secure and fast enterprise information management. Specifically, this embodiment discloses a terminal device for a DHR system based on RFID, see reference... Figure 1 The understanding includes: an electronic tag, wherein the electronic tag is provided with an antenna and a first inductor, the antenna and the first inductor being connected to form a first induction loop; wherein the first induction loop is also provided with a first capacitor; a reader / writer, wherein the reader / writer is signal-connected to the antenna, wherein the reader / writer is provided with a second inductor and externally connected to a power supply, the second inductor and the power supply forming a second induction loop, the first induction loop and the second induction loop mutually induct when they are close to each other, and the first capacitor is used to charge when the first induction loop and the second induction loop mutually induct; a terminal, wherein the terminal is signal-connected to the reader / writer, wherein the output terminal of the reader / writer is signal-connected to the input terminal of the terminal; the terminal is also provided with a first communication module; and a display device, wherein the display device is signal-connected to the first communication module.
[0022] When an employee or object wearing an electronic tag passes by the reader, the reader exchanges signals with the antenna on the electronic tag via its own antenna. This signal exchange relies on the mutual inductance between the first and second sensing circuits. When the two sensing circuits approach each other, the first capacitor charges under the mutual inductance, thereby activating the electronic tag. After activation, the electronic tag sends the stored employee or object information to the reader. Upon receiving the information, the reader transmits it to the terminal via a signal connection. The terminal processes this information and sends the processing results to the display device via the first communication module. The display device then displays this information, thereby enabling rapid identification and information management of employees or objects, ensuring the security and efficiency of enterprise information management.
[0023] Second embodiment: Based on the foregoing embodiments, in this example, the reader / writer further includes a radio frequency receiver, an analog-to-digital converter module, a processing unit, and a clock circuit; the radio frequency receiver is signal-connected to the antenna, and the radio frequency receiver is used to receive the modulation signal transmitted by the antenna; the analog-to-digital converter module is signal-connected to the radio frequency receiver, and the analog-to-digital converter module is used to convert the modulation signal into a digital signal; the processing unit is signal-connected to the analog-to-digital converter module, and the processing unit has built-in programs and algorithms, and the processing unit is used to decode the digital signal.
[0024] For example, the device is used for employee information management. When an employee wearing an electronic tag enters the signal range of the reader, the tag, which contains an antenna and a first inductor, forms a first sensing loop capable of triggering mutual inductance upon approaching the reader. The reader interacts with the tag's first sensing loop through its own antenna and a second sensing loop, causing a first capacitor to charge and thus activating the tag. Once activated, the tag begins transmitting a modulated signal through its antenna, containing the employee's identification information.
[0025] The reader / writer is responsible for receiving modulated signals from the electronic tags. Once these signals are received, the radio frequency receiver transmits them to the analog-to-digital converter (ADC). The ADC converts the received analog signals into digital signals for further processing. After the digital signal conversion is complete, the digital data is sent to the processing unit inside the reader / writer.
[0026] The processing unit has a built-in program and algorithm for parsing and decoding the digital signals received from the analog-to-digital converter module, thereby extracting employee information. The decoded information is then transmitted to the terminal.
[0027] The terminal sends the processed data to a connected display device via its first communication module. The display device then shows this employee information, such as the employee's name, position, and department, enabling managers to monitor and manage employee activities and status in real time.
[0028] In some specific examples, the electronic tag is used to store the modulated signal; the reader / writer is used to receive the modulated signal and output an input sequence to the terminal. The input sequence is a set of binary codes containing data information. For example, in this example, the input sequence contains detailed employee information received from the electronic tag, storing the employee's personal identification number, name, position, and department information in binary code. This input sequence is first processed by the processing unit according to a preset program and algorithm to verify and format the data, ensuring it meets the requirements of the enterprise information system. The processed data sequence is sent by the terminal's communication module to a connected display device in a standardized data format. Simultaneously, this information can also be forwarded to the enterprise's main database or other relevant management systems for further analysis and recording. On the display device, this data is presented in an easy-to-read format, allowing managers to see clear employee information cards, including photos, names, departments, and positions, as well as other information customized according to the enterprise's needs.
[0029] Furthermore, the input sequence is not limited to display. It can also trigger a series of automated workflows, such as employee access records, time management, and security verification. For example, when an employee enters a specific secure area, the system can automatically check their security permissions to ensure that only employees with the appropriate permissions can enter these areas. This functionality greatly improves the efficiency and accuracy of enterprise security management.
[0030] The same device is used to record departure times when employees finish their workday and leave the company, thus automatically calculating working hours and simplifying time management and payroll calculation processes. Furthermore, this automatic recording of information helps the human resources department track employee attendance, manage leave, and handle attendance anomalies.
[0031] Third embodiment: Based on the foregoing embodiments, continue to refer to Figure 1 The terminal includes: a processing module, which is signal-connected to the reader / writer and also signal-connected to the first communication module; and a storage module, which is signal-connected to the processing module.
[0032] The processing module first receives the input sequence. Based on the information in the sequence, it generates read commands for the storage module. These commands are highly specific, instructing the storage module to retrieve data records matching the input sequence. Upon receiving the commands, the storage module searches its database to find data matching the provided employee information. Once this data is found, the storage module sends it back to the processing module as an output sequence. Upon receiving the output sequence from the storage module, the processing module performs final data processing. This includes data verification, formatting, and preparation for display. The processing module ensures that all received data is up-to-date and meets the company's requirements. Afterward, the processing module sends this prepared data to the first communication module, which is responsible for transmitting the data to the display device. On the display device, the output sequence is transformed into detailed employee information cards. These information cards include not only basic personal information such as name and job title, but may also include more specific data such as recent performance reviews, security permission levels, and last login time.
[0033] Fourth embodiment: Based on the foregoing embodiments, continue to refer to... Figure 1 This embodiment also includes a cloud system. In this example, the cloud system is signal-connected to the terminal and to the reader / writer. In this example, the cloud system performs real-time data overwriting on the storage module.
[0034] Specifically, the reader / writer is also connected to the cloud system via a third communication module. The reader / writer sends the input sequence read each time to the cloud system through the third communication module, and the cloud system records it. The storage module is also connected to the cloud system via a second communication module. Through the second communication module, the cloud system updates the storage module in real time.
[0035] Fifth Embodiment: Based on the foregoing embodiments, in a specific example, further reference can be made to... Figure 3 To understand this, the processing module includes: an I / O interface for receiving the input sequence and converting the input sequence into a first digital signal; a CPU, which is electrically connected to the I / O interface, and the CPU is also electrically connected to RAM and ROM; wherein, the CPU is used to: read a first command stored in the ROM according to the first digital signal, and read an output sequence from the storage module according to the first command; the RAM is used to: convert the output sequence into a second digital signal, and send the second digital signal back to the CPU.
[0036] In this example, refer to Figure 1-2 Understanding the structure shown, when an employee or object wearing an electronic tag passes through the reader, the first inductive loop formed by the antenna on the tag and the first inductor is activated, triggering mutual inductance with the second inductive loop in the reader. This action causes the first capacitor to charge, thereby activating the electronic tag and causing it to begin transmitting a modulated signal through its antenna. This modulated signal contains the employee's identification information, such as their personal identification number and name.
[0037] After receiving these modulated signals, the reader captures them via an RF receiver and transmits them to the analog-to-digital converter (ADC). In the ADC, the modulated signals are converted into digital signals and then sent to the processing module. In the processing module, specifically at the I / O interface described in this embodiment, these digital signals are received and converted into a first digital signal.
[0038] This first digital signal is then sent to the CPU, the core of the processing module, responsible for handling all computational and data processing tasks. The CPU first reads a preset first command from its connected ROM. These commands define how to read the corresponding data from the storage module based on the received first digital signal. This data is considered the output sequence, including detailed employee information and possible historical records.
[0039] Once the CPU retrieves the required output sequence from the storage module, this data is sent to RAM. In RAM, the output sequence is converted into a second digital signal. This conversion process includes not only simple data format conversion but may also involve data caching to speed up subsequent data access.
[0040] Finally, the second digital signal is sent back to the CPU. The CPU determines how to further process these signals based on the system configuration and current operational requirements. The processed data is then sent via the CPU to the first communication module, which is responsible for transmitting the data to the display device. On the display device, the data is presented to managers in an easy-to-understand and operable format, allowing them to monitor and manage employee activities and status in real time.
[0041] Sixth Embodiment: Based on any of the foregoing embodiments, the cloud system is a cloud system based on the Dynamic Heterogeneous Redundancy (DHR) model, refer to... Figure 3 It is understood that the cloud system functional units include functional components such as a distributor, a multi-mode adjudication module, a negative feedback controller, user interaction, and a heterogeneous execution pool. The heterogeneous execution pool supports heterogeneity at multiple levels, including hardware instruction sets, operating systems, and applications.
[0042] Specifically, cloud systems include:
[0043] An input proxy module is responsible for receiving input data from external sources (such as signals emitted by employees or devices via electronic tags). This module distributes the received data stream to subsequent processing flows. It sends the data to different heterogeneous execution pools based on the data type or processing priority.
[0044] A heterogeneous execution pool comprises several heterogeneous execution units, each running on a different hardware instruction set, operating system, or application layer. The cloud system can select the most suitable execution unit for data processing based on task requirements, thereby optimizing processing efficiency and system resource utilization. The existence of the heterogeneous execution pool allows the system to handle a wide variety of tasks, from simple data queries to complex data analysis and processing.
[0045] After the heterogeneous executor pool has completed its processing, the results are sent to the multi-mode adjudication module. This module evaluates the outputs of each heterogeneous executor and performs a redundancy check. By comparing the outputs of multiple executors, the final correct result is determined, ensuring the accuracy and reliability of the system's output.
[0046] A negative feedback controller adjusts system behavior based on voting results. If the multi-mode decision-making module detects frequent deviations in the results of certain executors, the negative feedback controller will adjust the task allocation of these executors or perform necessary adjustments and optimizations. Furthermore, this unit is also responsible for dynamically adjusting resource allocation and optimizing system performance based on real-time performance feedback.
[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
