Wherein, each terminal device may be, for example, a desktop computer, a notebook computer, a tablet computer, a mobile device, or a personal digital device. In some embodiments, the blockchain network 250 may be a network architecture consisting of a cluster of servers on the network utilizing blockchain technology.

In some embodiments, server 240 may be a server, a server cluster, or a cloud server. In some embodiments, the server 240 includes a processing circuit 242 and a storage module 244 . The storage module 244 is used for storing various data involved in the operation of the working timing method, such as working hours, comparison images, working images, and message summaries corresponding to working hours and working images. The processing circuit 242 is used for executing the steps involved in the server 240 when the work timing method is executed.

In some embodiments, the work timing system 100, the wireless sensor 210, the worker terminal 220, and the employer terminal 230 are in the same local area network, and the server 240 and the blockchain network 250 are not in this local area network , that is, the work timing system 100 is in the Internet, but the embodiment of the present invention is not limited to this. In some embodiments, the employer terminal 230 may also be on the Internet relative to the work timing system 100 . In another embodiment, the work timing system 100 , the wireless sensor 210 , the worker terminal 220 , the employer terminal 230 , the server 240 and the blockchain network 250 may also be in the same local area network.

The processor 120 is coupled to the communication module 110 . The processor 120 is used for controlling the operation of the communication module 110 and processing data and signals. In some embodiments, the processor 120 may be an arithmetic circuit such as a central processing unit, a microprocessor, an application-specific integrated circuit (ASIC, Application-specific Integrated Circuit), or a system on a chip (SOC, System on a Chip).

Please refer to Figure 1 and Figure 2 at the same time. First, the processor 120 detects the sensing signal from the wireless sensor 210 via the communication module 110 (step S200). The sensing signal is generated by the wireless sensor 210 sensing the identification card of the worker. The identification card can be an active or passive device with a chip and an induction coil matching the local end short-range communication function of the wireless sensor 210 .

Here, the processor 120 generates a timing command (step S202 ) or an end command (step S302 ) according to the sensing signal.

After step S202, the working hours corresponding to the worker's identification card are accumulated according to the timing instruction (step S204). In some embodiments, the work timing system 100 also includes a counter 130A. Here, the processor 120 is further coupled to the counter 130A and controls the operation of the counter 130A. In an embodiment of step S204, the processor 120 generates a timing command and starts the counter 130A with the timing command, so that the counter 130A responds to the timing command to count up according to its own clock signal, thereby accumulating the working hours. For example, the counter 130A accumulates the working hours in a manner of incrementing every one hour, but the embodiment of the present invention is not limited to this. In some embodiments, the work timing system 100 further includes a storage device 150 . Here, the processor 120 is also coupled to the storage device 150 and controls access to the storage device 150 . The processor 120 may store the working hours accumulated by the counter 130A or the counts of the accumulated corresponding working hours in the storage device 150 . In some embodiments, the counter 130A may be implemented by a circuit composed of a plurality of flip-flops or by a chip with a counting function. In some examples, counter 130A may be, for example, but not limited to, an asynchronous counter, a synchronous counter, a decimal counter, a ring counter, a Jensen counter, and the like. In some examples, the storage device 150 may be a non-volatile storage medium such as flash memory, ROM, hard disk or solid state disk. In some examples, the storage device 150 may be a non-volatile storage medium such as flash memory, ROM, hard disk or solid state disk.

After step S204, the processor 120 receives at least one working image sent by the worker terminal 220 via the communication module 110 (step S206). For example, the processor 120 sends out the image capture signal and transmits it to the worker terminal 220 through the communication module 110 . The worker terminal 220 captures the image of its own screen in response to the image capture signal, and transmits the image of the screen as a working image to the processor 120 through the communication module 110; The user terminal 220 drives its own front lens to capture an image in response to the image capture signal, and sends the captured image back to the processor 120 via the communication module 110 as a working image.

In some embodiments, the processor 120 may periodically receive at least one working image from the worker terminal 220 via the communication module 110 . For example, the processor 120 receives at least one working image from the worker terminal 220 through the communication module 110 every five seconds or ten seconds, or the processor 120 sends an image capture signal through the communication module 110 every five seconds or ten seconds. to the worker terminal 220. The processor 120 may also aperiodically receive at least one working image from the worker terminal 220 via the communication module 110 or send an image capture signal to the worker terminal 220 via the communication module 110 .

After step S206, the processor 120 identifies each working image received from the worker terminal 220 to generate a corresponding identification result (step S208). For example, the processor 120 obtains, through the communication module 110 , a plurality of comparison images (for example, corresponding to the face images set on the identification card or the storage device 150 ) stored in the storage module 244 (or the storage device 150 ) in the server 240 . The image corresponding to the work content of the project), and perform face recognition (or work content image recognition) on each work image according to the control image to generate a recognition result. For example, the processor 120 compares the matching degree between the feature points of the comparison image stored in the storage module 244 (or the storage device 150 ) and the feature points of the working image, and when the matching degree is greater than a certain ratio (for example, greater than 95%) , it means that the identification result is that the control image corresponds to the working image; on the contrary, if the matching degree is less than a certain ratio, it means that the identification result is that the control image does not correspond to the working image. In some embodiments, the work content may be project-related information. In some examples, the work content is, for example, regulations, letters of evidence, reports, etc. that workers need to use when handling projects.

In some embodiments, the comparison image includes a work image previously recognized by the processor 120 , an image corresponding to the face set on the identification card, an image corresponding to the work content of the project, or a combination thereof. For example, after the processor 120 recognizes the working image, the processor 120 stores the identified working image as a comparison image in the storage module 244 in the server 240 (or in the storage device 150 via the communication module 110 ). ) for receiving the working image from the worker terminal 220 next time (step S206 ) and identifying the newly received working image (step S208 ). Here, the image corresponding to the face set on the identification card, the image corresponding to the work content of the project, and the previously identified work image are used for identification, so as to improve the accuracy of face identification.

After step S208, the processor 120 determines whether the identification result satisfies the pause condition or the resume condition (step S210). If at least one identification result satisfies the suspension condition, the processor 120 suspends accumulating the working hours (step S212 ); if any identification result satisfies the continuing condition, the processor 120 continues accumulating the working hours (step S214 ). The pause condition includes that the working image currently recognized by the processor 120 does not correspond to the control image, that is, the recognition result of the working image currently recognized by the processor 120 is that the working image does not correspond to the control image. The continuing condition includes that the working image currently recognized by the processor 120 corresponds to the control image, that is, the recognition result of the working image currently recognized by the processor 120 is that the working image corresponds to the control image. For example, when at least one identification result satisfies the suspend condition, the processor 120 sends a suspend command to the counter 130A, so that the counter 130A suspends the accumulated working hours. On the contrary, when any identification result satisfies the continuation condition, the processor 120 sends a continuation command to the counter 130A, so that the counter 130A continues to accumulate the working hours. In some embodiments, when the accumulated working hours are suspended, the processor 120 still periodically receives and recognizes working images from the worker terminal 220 . and identify any When the result satisfies the continuation condition, the processor 120 starts the counter 130A again, so that the counter 130A continues to accumulate the working hours. In an example, the resume command and the pause command may be a high-level signal and a low-level signal, respectively.

In some embodiments, when the processor 120 suspends the accumulated working hours, the processor 120 can generate a pause timing notification and transmit it to the worker terminal 220 via the communication module 110 , and then display the pause on the user interface of the worker terminal 220 Timing notifications to let workers know that work hours are currently on hold when they see a pause timing notification. In some embodiments, the user interface of the worker terminal 220 may be a display interface such as a display screen, a touch screen, or the like. The timeout notification may be presented in a visually identifiable manner (such as displaying in another color on the user interface or flashing a window, etc.), but the embodiment of the present invention is not limited thereto. By obtaining and identifying the work image at any time, the working status of the worker can be known (that is, through the fact that the working image does not correspond to the control image, it can be known that the worker may be dealing with affairs that are not related to the work content or that the worker is not using the work. user terminal 220 (for example, using the worker terminal 220 without sitting in front of the worker terminal 220 )) to suspend or continue accumulating working hours in a timely manner, so as to accurately accumulate working hours and improve the accuracy of work timing and the efficiency of work. efficiency.

In some embodiments, referring to FIG. 1 and FIG. 3 , if the recognition results of the working images satisfy the pause condition, the processor 120 may first determine whether the recognition results of two consecutive work images satisfy the pause condition (step S211 ). If no two consecutive identification results satisfy the pause condition, the processor 120 does not act (eg, keeps the counter 130A continuously counting) and continues to periodically receive new working images through the communication module 110 (step S206 ); The recognition result of each working image satisfies the suspension condition, and the processor 120 causes the counter 130A to suspend the accumulation of working hours (step S212 ). Accumulated work is suspended only after it is judged twice in a row that the suspension conditions are met. Working hours can improve the flexibility and accuracy of work timing. For example, workers go to the toilet to meet their physiological needs.

After starting the timing (eg after step S204, step S212 and step S214), the processor 120 continues to detect and determine whether the communication module 110 receives the sensing signal from the wireless sensor 210 again (step S205). If the processor 120 detects the sensing signal again, it generates an end command according to the sensing signal (step S302). If the processor 120 does not detect the sensing signal again, the processor 120 continues to receive a new working image from the worker terminal 220 via the communication module 110 (step S206 ) and continues to execute subsequent steps.

After step S302, the accumulation of operating hours is stopped according to the end instruction (step S304). For example, the processor 120 generates and sends an end command to the counter 130A, so that the counter 130A stops accumulating the working hours in response to the end command, that is, stops counting times. Wherein, the end command can be a disable signal. When stopping accumulating the working hours (step S304 ), the processor 120 associates the working hours with at least one working image (step S306 ). In some embodiments, after stopping the accumulation of working hours (step S304 ), the processor 120 may further display the working hours and their associated working images on the corresponding worker terminal 220 or the employer terminal 230 through the communication module 110 The user interface of the , so that the worker can know the working hours and the corresponding working image through the user interface of the worker terminal 220 or the employer through the user interface of the employer terminal 230 . In some embodiments, the user interface of the employer terminal 230 may be a display screen, a touch screen, or the like.

In some embodiments, after storing the accumulated working hours, the processor 120 may reset the counter 130A to zero to clear the count value for the accumulated working hours.

In some embodiments, the processor 120 receives the sensing according to the communication module 110 The number of signals, and a timing command is generated when the sensing signal is detected for the first time (step S202 ). After the processor 120 starts accumulating the working hours (step S204 ), it further determines whether the induction signal is detected again (step S205 ). For example, the processor 120 periodically detects whether there is a sensing signal again (eg, detects and determines whether there is a sensing signal every five seconds or ten seconds) or detects whether there is a sensing signal again aperiodically. If the processor 120 determines that the sensing signal is detected again (that is, the sensing signal generated by the sensing identification card from the wireless sensor 210 is received through the communication module 110 for the second time), the processor 120 generates an end command (step S302 ). ).

In some embodiments, referring to FIG. 4 , after the processor 120 detects the induction signal (step S200 ), the processor 120 obtains an identifier corresponding to the identification certificate according to the induction signal (step S400 ). The identifier may be a serial number, a worker's job number, a factory serial number of the identification certificate, a Media Access Control (MAC) address, and the like. In some embodiments, after obtaining the identifier corresponding to the identifier, the processor 120 stores the identifier in the storage module 244 of the server 240 or the local storage device 150 .

In some embodiments, referring to FIG. 4 , after step S400 , the number of times the sensing signal is received is accumulated according to the sensing signal (step S402 ). In some embodiments, the work timing system 100 also includes a counter 130B. The processor 120 is also coupled to the counter 130B and used to control the operation of the counter 130B. For example, after step S400, the processor 120 sends an actuation signal to the counter 130B, so that the counter 130B is actuated according to the actuation signal and accumulates the number of times the communication module 110 receives the sensing signal. In an exemplary embodiment, each time the processor 120 detects a sensing signal, the counter 130B accumulates the number of times through the actuation signal.

In some embodiments, referring to FIG. 4 , after step S402 , the processor 120 determines whether the number of times of the sensed signal accumulated in the storage device 150 is an odd number or an even number (step S402 ). S404). If the number of sensing signals is an odd number, the processor 120 generates a timing command (step S202 ), and accumulates the working hours according to the timing command (step S204 ), and then the processor 120 determines whether the sensing signal is detected again (step S205 ). If the processor 120 detects the induction signal again, the processor 120 obtains the identifier of the identification certificate corresponding to the new induction signal according to the new induction signal (step S400 ) (not shown), and determines whether the current identifier corresponds to to the previous identifier (step S406). If the current identifier corresponds to the previous identifier (for example, the identifier obtained from the sensing signal for the second time (the new identifier, that is, the latest identifier stored in the storage module 244 or the storage device 150 ) corresponds to The first time based on the identifier obtained from the sensing signal (the old identifier, that is, the identifier previously or previously stored in the storage module 244 or the storage device 150 )), according to the accumulated number of times the sensing signal is received ( Step S402 ), and the processor 120 again determines whether the number of times of the sensed signal accumulated in the storage device 150 is odd or even (step S404 ). If the number of times of the sensing signal is an even number, the processor 120 generates an end command (step S302). On the contrary, if the current identifier does not correspond to the previous identifier (for example, the identifier obtained according to the sensing signal for the second time does not correspond to the identifier obtained according to the sensing signal for the first time), the processor 120 generates an indication of The prompt of the sensing failure is sent to the worker terminal 220 via the communication module 110 , so that the prompt indicating the sensing failure is displayed on the user interface of the worker terminal 220 . Then, the processor 120 will continue to detect and determine whether the sensing signal is detected again (step S205 ) (not shown) or receive the next working image from the worker terminal 220 (step S206 ). In some embodiments, the prompt indicating the failure of the sensing may be a text window popped up on the user interface, or a prompt notification with different colors flashing, but the embodiment of the present invention is not limited thereto. In some embodiments, the counter 130B may be implemented by a circuit composed of a plurality of flip-flops or by a counter 130B function of the chip to achieve. The counter 130B may be, for example, but not limited to, an asynchronous counter, a synchronous counter, a decimal counter, a ring counter, a Jensen counter, and the like. In some embodiments, the counter 130A and the counter 130B may be integrated into a single counting unit.

In some embodiments, in addition to the counter 130A and the counter 130B, the work timing system 100 may also include a plurality of other counters, so that the processor 120 can make the counter 130A, the counter 130B and the other plurality of counters according to different identifiers in the The times or working hours corresponding to different identifiers are accumulated in the storage device 150 .

In some embodiments, after stopping the accumulation of working hours (step S304 ), the processor 120 causes the counter 130B to clear the count value for accumulating the times of the sensing signal.

In some embodiments, referring to FIG. 5 , after step S306, the processor 120 encrypts the working hours of the current work, all working images received during the accumulative working hours, or a combination thereof, and obtains the corresponding working hours accordingly. The encryption result (hereinafter referred to as the first encryption result) (step S308 ) is then stored in the storage module 244 of the server 240 or the local storage device 150 via the communication module 110 (step S310 ). For example, the processor 120 performs operations on the accumulated working hours and working images with a hash function (Hash) or a hash message authentication code (HMAC) algorithm to generate a corresponding message digest (ie, step S308 ). , and store the generated message digest in the storage module 244 or the storage device 150 in the server 240 via the communication module 110 (step S310 ). In some embodiments, before obtaining the first encryption result (step S308 ), the processor 120 copies the working hours and the working image to generate a backup file (ie, original data). In some embodiments, the processor 120 stores the backup files generated by copying the working hours and working images in the storage module 244 or the storage device 150 . In some embodiments, after the processor 120 obtains the first encryption result (step S308 ), the processor 120 may store the first encryption result in the storage module 244 (or the storage device 150 ) in priority compared with the backup file, and may store the backup file in the storage module 244 with a lag compared with the first encryption result (or storage device 150) (step S310).

In some embodiments, when the processor 120 receives the working image from the worker terminal 220 via the communication module 110 (step S206 ) or performs subsequent actions, the processor 120 can encrypt the received working image and obtain the first encryption The results are stored in the storage module 244 (or the storage device 150 ) in the server 240 .

In some embodiments, referring to FIG. 6 , after step S306 , the processor 120 can further encrypt the working hours of the current work, all working images received during the accumulative working hours, or a combination thereof, and obtain Corresponding another encryption result (hereinafter referred to as the second encryption result) (step S312 ), and then the second encryption result is stored in the blockchain network 250 via the communication module 110 (step S314 ). For example, the processor 120 encrypts the working hours, the at least one working image, or a combination thereof through a one-way hash function operation, and generates hash parameters corresponding to the working hours, the at least one working image, or a combination thereof (ie, step S312 ). , and then store the hash parameters in the blockchain network 250 via the communication module 110 (ie, step S314 ). In some examples, one-way hash functions such as, but not limited to, the MD5 algorithm, the SHA-1 algorithm, the SHA-256 algorithm, the SHA-384 algorithm, the SHA-512 algorithm, and the like.

In this way, the worker terminal 220 or the employer terminal 230 can compare the second encryption result (eg, hash parameter) in the blockchain network 250 with the first encryption result in the storage module 244 (or the storage device 150 ). Whether the encryption results (eg message digests) are the same or have a corresponding relationship is used to verify the working hours and at least one working image, and to confirm whether the working hours or at least one working image have been tampered with. If the second encryption result (for example: hash parameter) and When the first encryption results (eg, message digests) are the same or have a corresponding relationship, the verification is passed, that is, the working hours and at least one working image have not been tampered with. Therefore, the reliability of the data (working hours and working images) can be further improved.

In some embodiments, the steps of obtaining the second encryption result (step S312 ) and storing the second encryption result in the blockchain network 250 (step S314 ) may be the same as obtaining the first encryption result (step S308 ) and storing the first encryption result (step S308 ). The steps of storing the encryption result in the storage module 244 (or the storage device 150 ) (step S310 ) are concurrently performed.

It should be noted that although the steps are described in sequence, this sequence is not a limitation of the present invention, and those skilled in the related art should understand that the execution sequence of some steps can be performed simultaneously or reversed under reasonable circumstances. For example, steps S304 to S314 may be performed substantially simultaneously; steps S202 and S204 may be performed substantially simultaneously; and steps S206 and S208 may be performed substantially simultaneously.

In some embodiments, after receiving the working image, the processor 120 may store the second encrypted result after encrypting the working image in the blockchain network 250, that is, in step S206 or its subsequent steps, the processor 120 can store the second encryption result (eg, hash parameter) obtained by encrypting the working image in the blockchain network 250 via the communication module 110 .

In some embodiments, the processor 120 stores the plurality of projects in the storage module 244 (or the storage device 150 ) in the server 240 via the communication module 110 . In an example of step S306, the processor 120 can associate the working hours and the corresponding working images to one of these projects (step S306). For example, the processor 120 sends a classification command to the server 240 through the communication module 110, and the processing circuit 242 of the server 240 generates a plurality of project folders corresponding to different projects in the storage module 244 according to the classification command. Or, where The processor 120 creates a plurality of project folders corresponding to different projects in the storage device 150 . After stopping the accumulation of the working hours (step S304 ), the processor 120 stores the working hours and working images of the current work in the project folder of the corresponding project.

In some embodiments, the report notification can be a notification with multiple color flashes or a text message. Wherein, the text message can be, for example, the reward content carried by the employer terminal 230 in the reward signal. In some examples, the report content may be a problem point corresponding to working hours or working images.

In some embodiments, the work timing system 100 further includes a voice module 140 . The processor 120 is also coupled to the voice module 140 and used to control the operation of the voice module 140 . In some embodiments, the processor 120 may receive the naming voice via the voice module 140, and add or modify the name corresponding to the project according to the naming voice. For example, the processor 120 performs semantic analysis on the naming speech received by the speech module 140 to obtain the corresponding text content, and adds or modifies the name of the project folder of the project according to the text content, so that the The name corresponds to the text content. For example, the processor 120 adds or modifies the universal unique identifier of the project folder of the corresponding project according to the text content, so that the name of the project folder of the project corresponds to the text content.

In some examples, the audio transceiver device is, for example, but not limited to, a device with a microphone and/or sound, a smart speaker, and the like.

In some embodiments, the processor 120 selects a working image that does not correspond to the work content as an excluded image (also called a non-working image), and does not associate the working hours associated with the excluded image to its currently associated project, that is, shifts Excludes the relationship between the work hours associated with the excluded image and the currently associated project. For example, the worker views the working image of the storage module 244 (or the storage device 150 ) stored in the server 240 by operating the user interface of the worker terminal 220 , and operates the user interface of the worker terminal 220 . And select the work image that does not correspond to the work content. The worker terminal 220 generates a selection signal according to the selected work images, and sends the selection signal to the work timing system 100 . The processor 120 of the work timing system 100 reads the work image (ie, the work image that does not correspond to the work content) in the project folder of the storage module 244 (or the storage device 150 ) according to the selection signal, which is associated with the selection signal, and The working image associated with the selection signal is selected as the excluded image, and then the working hours associated with the excluded image are not stored in the currently stored project folder. For example, the processor 120 deletes the working hours associated with the excluded image from its currently stored project folder. In this way, it can be ensured that the number of working hours corresponding to each project is the time that the worker actually works.

In some embodiments, the processor 120 may be coupled to the communication module 110 , the counter 130A, the counter 130B, the voice module 140 and the storage device 150 via a bus.
