In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0070] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0071] The present invention discloses an electrostatic risk monitoring method and device based on an electrostatic wristband system, which obtains status information of multiple wristbands in the electrostatic wristband system through the communication path corresponding to the wristband, determines the risk status of any wristband according to the status information of the wristband, and can obtain the risk information of the electrostatic wristband system, thereby improving the accuracy and efficiency of determining the risk information of the electrostatic wristband system. The following are detailed descriptions.

[0072] Embodiment 1

[0073] See also Figure 1 , Figure 1 : is a flow chart of a static risk monitoring method based on an static bracelet system disclosed in an embodiment of the present invention. Figure 1 The described electrostatic risk monitoring method based on the electrostatic wristband system can be applied to the electrostatic risk monitoring system, and can also be applied to the electrostatic wristband monitoring system, which is not limited in the embodiments of the present invention. Figure 1 As shown, the electrostatic risk monitoring method based on the electrostatic wristband system may include the following operations:

[0074] 101. Send a status acquisition request to at least one anti-static wristband according to the communication path information.

[0075] In an embodiment of the present invention, the electrostatic wristband system includes a plurality of electrostatic wristbands, and each electrostatic wristband is configured to have corresponding communication path information.

[0076] In an embodiment of the present invention, optionally, the risk status information of the electrostatic wristband can be transmitted by time division multiplexing, that is, different signals are transmitted in different time periods of the same physical connection. Optionally, a lora communication module can be set on the electrostatic wristband, which enables the wristband device to upload its own status to the management device, and use time division multiplexing to allow the host computer (including the data convergence layer (hereinafter referred to as the convergence layer), PC end) to receive the information of the lower computer: all received data are uniformly collected and processed at the convergence layer, and the serial number of the corresponding slave machine is generated according to the module address and channel. After processing, the data of multiple slave machines are periodically combined and forwarded to the PC end (also known as the computer end, a type of host computer) for reception, so that a single device can manage hundreds of wristband slave machines. For example, assuming that a single aggregation layer host can receive the status of 20 slaves in one channel within 5 seconds, that is, the data aggregation host sends a command and broadcasts it to all devices. It takes 5 seconds for 20 devices to feedback, 10 seconds to receive 40 devices, and so on; at the same time, each aggregation layer host receives data using different channels at the same time. When the number of channels is 100 (from 410 to 510MH), 100 hosts can manage up to 2,000 wristband devices at the same time within 5 seconds, which is convenient and effective to achieve simultaneous management of multiple electrostatic wristbands.

[0077] 102. Obtain signal feedback sent by any anti-static wristband in response to a status acquisition request, and determine risk status information corresponding to the anti-static wristband according to the signal feedback.

[0078] In the embodiment of the present invention, the risk status information of the static electricity wristband may include at least one of a normal state, a shutdown state, an alarm state, and an off-duty state. The alarm state is a state in which the wearer of the wristband is detected to have taken off the wristband without leaving the job.

[0079] Optionally, a wristband status detection circuit is used to detect whether the user is wearing a wristband, and then the MCU control module identifies the voltage change in the detection circuit and outputs the status of the electrostatic wristband.

[0080] Optionally, the bracelet status detection circuit structure can be as follows Figure 2As shown, the LM324 component has four op amps. When the user wears the bracelet, the whole body is equivalent to a resistor connected to the circuit. When the arm leaves the bracelet, due to the change in resistance, the detection circuit generates an oscillation signal through the capacitor of the LM324 first-level op amp. The second-level op amp acts as a comparator. The reverse input terminal fixes the voltage at half the input voltage through R8 and R9. The output terminal also outputs oscillation due to the oscillation output of the first-level op amp, so the green light cannot light up due to the input oscillation signal. The third-level op amp of LM324 reverses the oscillation signal output by the second-level op amp and inputs it into the fourth-level op amp. The fourth-level op amp signal follows to make the red light flash and the buzzer sound an alarm. When the off-duty switch is turned on, the output voltage of the second-level op amp switches to a high voltage. At this time, the green light lights up due to the high input voltage and the red light stops flashing due to the low input voltage. The range of oscillation can be adjusted by adjusting the sliding resistor. It can be seen that the bracelet detection circuit can detect whether the user is wearing a bracelet. When the bracelet is not worn, an alarm will be sounded and the red light will flash. When the off-duty switch is turned on (that is, when the user is off-duty), the red light will stop flashing and the green light will turn on to lift the alarm.

[0081] Among them, the MCU (Microcontroller Unit, referred to as MCU, also known as a single-chip microcomputer or single-chip microcomputer) control module can obtain the output of the secondary op amp and the four-stage op amp in real time, so as to synchronously obtain the signal obtained by the detection circuit. Specifically, when the secondary op amp is the first high voltage and the four-stage op amp is the low voltage, that is, when the green light of the detection circuit is on and the red light is off, the MCU outputs the state of the anti-static wristband as the normal state; when the secondary op amp and the four-stage op amp do not detect a signal, the MCU outputs the state of the anti-static wristband as the shutdown state; when the secondary op amp is an oscillating signal and the four-stage op amp is an oscillating signal (opposite to the oscillating signal of the secondary op amp), that is, when the red light of the detection circuit flashes and the green light is off, the MCU outputs the state of the anti-static wristband as the alarm state; when the secondary op amp is the second high voltage (different from the voltage value of the first high voltage in the normal state) and the four-stage op amp is the low voltage, the MCU outputs the state of the anti-static wristband as the off-duty state.

[0082] It can be seen that the embodiment of the present invention obtains the status information of multiple wristbands in the electrostatic wristband system through the communication path corresponding to the wristband, determines the risk status of any wristband according to the status information of the wristband, and can obtain the risk information of the electrostatic wristband system, thereby improving the accuracy and efficiency of determining the risk information of the electrostatic wristband system.

[0083] Optionally, the anti-static wristband alarm device can be composed of three circuit modules, namely, an anti-static wristband module, a detection circuit module (also called a wristband status detection circuit), and an alarm communication circuit module.

[0084] Among them, the alarm communication circuit can be composed of a voltage stabilizing module, an MCU control module, and a lora communication chip. When the MCU detects the signal of the previous bracelet circuit, it sends the data corresponding to the slave to the host through the relevant protocol. The MCU can store the configured channel address information in its own EPPROM. The voltage stabilizing circuit is powered to ensure operation.

[0085] Optionally, the data collection and forwarding equipment of the convergence layer can be composed of a power supply voltage regulator module, a communication module, and an MCU module. The function of the convergence layer host is mainly to send a broadcast query signal to the slave at a fixed time, receive the status of the slave within a specified time, and define it as a shutdown state if no reply is received from the slave. After receiving the status, the serial number is uniformly arranged according to the channel and address of the slave, and the information is packaged and forwarded to the PC through the serial port.

[0086] Optionally, the software part of the data collection and forwarding device at the aggregation layer is controlled by the FreeRTOS real-time operating system and is divided into three threads to perform task operations. The task of thread one is mainly to broadcast and collect the status of the bracelet slave device through the lora communication module. The task of thread two is mainly to forward data to the host computer through the 203 serial port. The task of thread three is mainly to process the commands received from the PC through the lora communication module or the 203 serial port, and to modify its own status through the command or forward it to the slave end for processing.

[0087] In an optional embodiment, the method further comprises:

[0088] Determine whether any electrostatic wristband meets the conditions for modifying wristband configuration;

[0089] When it is determined that the electrostatic wristband meets the wristband configuration modification condition, a modification instruction corresponding to the wristband configuration modification condition is sent to the electrostatic wristband, so that the electrostatic wristband modifies the configuration information of the electrostatic wristband according to the modification instruction.

[0090] In this optional embodiment, the configuration information includes communication path information and / or a time interval for sending feedback signals in time-sharing, wherein the communication path information includes a communication address and channel of the bracelet.

[0091] Optionally, the status of the handband slave can be modified through the host computer (including the aggregation layer host and PC). Figure 3 As shown, its functions include: querying the master-slave channel address, modifying the master-slave system, modifying the master-slave address, modifying the time interval of the slave time-sharing transmission, etc.; it can be modified with one key after entering the required configuration, and after the modification, the parameters can be saved on the modified device through EEPROM or FLASH, which is convenient for unified management.

[0092] Optionally, the aggregation layer host can simultaneously receive commands from the PC, modify its own channel, address, reply delay, etc. according to the commands, and can also modify the bracelet slave through commands, making it convenient for the management end to manage the slaves at the lowest level. Optionally, the host computer can be written in QT, which can be quickly transplanted to different systems to facilitate different system operations.

[0093] It can be seen that this optional embodiment can send the modification information to the wristband when it is determined that the electrostatic wristband needs to modify the configuration information so that the wristband itself modifies the configuration information, which is helpful for adjusting the configuration of the wristband according to the actual application environment and improving the adaptability of the wristband to the use environment.

[0094] In yet another optional embodiment, determining whether any electrostatic wristband meets the wristband configuration modification condition includes:

[0095] Determine the signal strength of the communication connection with the electrostatic wristband according to the signal feedback sent by the electrostatic wristband in response to the status acquisition request, and when the signal strength of the electrostatic wristband is lower than a preset strength, determine that the electrostatic wristband meets the wristband configuration modification condition; or

[0096] When a wristband configuration modification request for the electrostatic wristband is received from a maintenance personnel of the electrostatic wristband system, it is determined that the electrostatic wristband meets a wristband configuration modification condition.

[0097] It can be seen that this optional embodiment can determine whether the bracelet meets the configuration modification conditions according to the communication signal strength of the electrostatic bracelet and the request of the maintenance personnel, which helps to improve the accuracy and efficiency of determining whether the modification conditions are met.

[0098] In another optional embodiment, when it is determined that the electrostatic wristband meets the wristband configuration modification condition, a modification instruction corresponding to the wristband configuration modification condition is sent to the electrostatic wristband, so that the electrostatic wristband modifies the configuration information of the electrostatic wristband according to the modification instruction, including:

[0099] When the signal strength of the electrostatic wristband is lower than the preset strength, a modification instruction for modifying the wristband channel setting is sent to the electrostatic wristband, so that the electrostatic wristband modifies the channel setting of the electrostatic wristband according to the modification instruction.

[0100] It can be seen that this optional embodiment can send a channel modification instruction to the wristband when the communication signal of the wristband is low, which helps the wristband to modify the channel setting to improve the communication signal strength.

[0108] In the embodiment of the present invention, each anti-static wristband is configured to have corresponding workstation information, wherein the workstation information may include at least one of workstation location information, workstation number information, and current employee information of the workstation.

[0109] It can be seen that the embodiment of the present invention obtains the status information of multiple wristbands in the anti-static wristband system through the communication path corresponding to the wristband, determines the risk status of any wristband according to the status information of the wristband, and can obtain the risk information of the anti-static wristband system, thereby improving the accuracy and efficiency of determining the risk information of the anti-static wristband system; it can screen out wristbands in abnormal states, and determine the workstation information corresponding to the abnormal wristbands, which is helpful for locating the abnormal wristbands and / or corresponding employees according to the workstation information, and helps to solve the electrostatic risk in a timely manner and improve the efficiency of electrostatic risk supervision.

[0112] When it is detected that the static electricity monitoring personnel are wearing smart monitoring glasses, the smart monitoring glasses are controlled to project the workstation location maps and employee portraits corresponding to all abnormal static electricity wristbands onto the retina of the static electricity monitoring personnel through harmless lasers.

[0113] It can be seen that this optional embodiment informs the electrostatic monitoring personnel of the workstation location map of the abnormal wristband and the corresponding employee portrait by projecting laser through monitoring glasses, which helps to improve the efficiency and accuracy of monitoring information transmission.

[0118] In this optional embodiment, optionally, each electrostatic bracelet is provided with a light projection device.

[0119] It can be seen that when this optional embodiment determines that there is information that needs to remind employees, the prompt information will be projected to a designated area through a light projection device, which helps employees obtain prompt information through the projected content of the area, improves the efficiency of employees obtaining prompts in a timely manner, and improves the convenience of employees obtaining prompt information.

[0120] In yet another optional embodiment, determining whether there is prompt information that needs to be prompted to the target employee includes:

[0124] Based on the full-body image of the target employee, a torso area image of the target employee is segmented from the full-body image of the target employee, and based on the torso area image of the target employee, it is determined whether the target employee is wearing anti-static protective clothing. When it is determined that the target employee is not wearing anti-static protective clothing, it is determined that there is prompt information that needs to prompt the target employee; when it is determined that the target employee is wearing anti-static protective clothing, it is determined based on the torso area image of the target employee whether the zipper of the anti-static protective clothing of the target employee is located at a preset position. When it is determined that the zipper of the anti-static protective clothing of the target employee is not located at the preset position, it is determined that there is prompt information that needs to prompt the target employee.

[0125] It can be seen that this optional embodiment determines whether there is prompt information that needs to be prompted to the target employee by judging whether the employee is wearing protective equipment through facial images, judging whether the employee is wearing protective gloves through hand images, or judging whether the employee is wearing anti-static protective clothing through torso images, which helps to improve the accuracy and efficiency of determining whether there is prompt information that needs to be prompted to the target employee.

[0128] In this optional embodiment, the reference direction of the image is longitudinal (the longitudinal arrangement direction of the pixels in the image) or transverse (the transverse arrangement direction of the pixels in the image). In this optional embodiment, the ratio of the human head to the body is the ratio of the length of the human head to the length of the human body when the human body is standing.

[0129] It can be seen that this optional embodiment segments the image including the face from the full-body image by proportion, which helps to improve the accuracy and efficiency of segmenting the facial image.

[0138] It can be seen that this optional embodiment warns of static electricity risks by obtaining the number of times employees swing their arms, and reminds employees to release static electricity when the number of times is too high, which helps to reduce the static electricity risk of the anti-static wristband system.

[0146] Embodiment 3

[0147] See also Figure 3 , Figure 3 : is a schematic diagram of the structure of an electrostatic risk monitoring device based on an electrostatic wristband system disclosed in an embodiment of the present invention. Figure 3 The described electrostatic risk monitoring device based on the electrostatic wristband system can be applied to the electrostatic risk monitoring system, and can also be applied to the electrostatic wristband monitoring system, which is not limited in the embodiments of the present invention. Figure 3 As shown, the electrostatic wristband system includes a plurality of electrostatic wristbands, each of which is configured to have corresponding communication path information; the electrostatic risk monitoring device based on the electrostatic wristband system may include:

[0148] The sending module 301 is used to send a status acquisition request to at least one electrostatic wristband according to the communication path information;

[0149] An acquisition module 302 is used to acquire a signal feedback sent by any electrostatic wristband in response to a status acquisition request;

[0150] The determination module 303 is used to determine the risk status information corresponding to the anti-static wristband according to the signal feedback.

[0151] In an embodiment of the present invention, optionally, the risk status information of the electrostatic wristband can be transmitted by time division multiplexing, that is, different signals are transmitted in different time periods of the same physical connection. Optionally, a lora communication module can be set on the electrostatic wristband, which enables the wristband device to upload its own status to the management device, and use time division multiplexing to allow the host computer (including the data convergence layer (hereinafter referred to as the convergence layer), PC end) to receive the information of the lower computer: all received data are uniformly collected and processed at the convergence layer, and the serial number of the corresponding slave machine is generated according to the module address and channel. After processing, the data of multiple slave machines are periodically combined and forwarded to the PC end (also known as the computer end, a type of host computer) for reception, so that a single device can manage hundreds of wristband slave machines. For example, assuming that a single aggregation layer host can receive the status of 20 slaves in one channel within 5 seconds, that is, the data aggregation host sends a command and broadcasts it to all devices. It takes 5 seconds for 20 devices to feedback, 10 seconds to receive 40 devices, and so on; at the same time, each aggregation layer host receives data using different channels at the same time. When the number of channels is 100 (from 410 to 510MH), 100 hosts can manage up to 2,000 wristband devices at the same time within 5 seconds, which is convenient and effective to achieve simultaneous management of multiple electrostatic wristbands.

[0152] In an embodiment of the present invention, the risk status information of the anti-static wristband includes at least one of a normal state, a shutdown state, an alarm state and an off-duty state, and / or the risk status information of the anti-static wristband is transmitted in a time division multiplexing manner.

[0153] Optionally, a wristband status detection circuit is used to detect whether the user is wearing a wristband, and then the MCU control module identifies the voltage change in the detection circuit and outputs the status of the electrostatic wristband.

[0154] Optionally, the bracelet status detection circuit structure can be as follows Figure 2 As shown, the LM324 component has four op amps. When the user wears the bracelet, the whole body is equivalent to a resistor connected to the circuit. When the arm leaves the bracelet, due to the change in resistance, the detection circuit generates an oscillation signal through the capacitor of the LM324 first-level op amp. The second-level op amp acts as a comparator. The reverse input terminal fixes the voltage at half the input voltage through R8 and R9. The output terminal also outputs oscillation due to the oscillation output of the first-level op amp, so the green light cannot light up due to the input oscillation signal. The third-level op amp of LM324 reverses the oscillation signal output by the second-level op amp and inputs it into the fourth-level op amp. The fourth-level op amp signal follows to make the red light flash and the buzzer sound an alarm. When the off-duty switch is turned on, the output voltage of the second-level op amp switches to a high voltage. At this time, the green light lights up due to the high input voltage and the red light stops flashing due to the low input voltage. The range of oscillation can be adjusted by adjusting the sliding resistor. It can be seen that the bracelet detection circuit can detect whether the user is wearing a bracelet. When the bracelet is not worn, an alarm will be sounded and the red light will flash. When the off-duty switch is turned on (that is, when the user is off-duty), the red light will stop flashing and the green light will turn on to lift the alarm.

[0155] Among them, the MCU (Microcontroller Unit, referred to as MCU, also known as a single-chip microcomputer or single-chip microcomputer) control module can obtain the output of the secondary op amp and the four-stage op amp in real time, so as to synchronously obtain the signal obtained by the detection circuit. Specifically, when the secondary op amp is the first high voltage and the four-stage op amp is the low voltage, that is, when the green light of the detection circuit is on and the red light is off, the MCU outputs the state of the anti-static wristband as the normal state; when the secondary op amp and the four-stage op amp do not detect a signal, the MCU outputs the state of the anti-static wristband as the shutdown state; when the secondary op amp is an oscillating signal and the four-stage op amp is an oscillating signal (opposite to the oscillating signal of the secondary op amp), that is, when the red light of the detection circuit flashes and the green light is off, the MCU outputs the state of the anti-static wristband as the alarm state; when the secondary op amp is the second high voltage (different from the voltage value of the first high voltage in the normal state) and the four-stage op amp is the low voltage, the MCU outputs the state of the anti-static wristband as the off-duty state.

[0156] It can be seen that the embodiment of the present invention obtains the status information of multiple wristbands in the electrostatic wristband system through the communication path corresponding to the wristband, determines the risk status of any wristband according to the status information of the wristband, and can obtain the risk information of the electrostatic wristband system, thereby improving the accuracy and efficiency of determining the risk information of the electrostatic wristband system.

[0157] In an optional embodiment, if Figure 4 As shown, each anti-static wristband is configured to have corresponding workstation information; the device may also include:

[0158] The first judgment module 304 is used to judge whether the electrostatic wristband is in an abnormal state according to the risk state information of each electrostatic wristband, so as to screen out all abnormal electrostatic wristbands in an abnormal state from all the electrostatic wristbands;

[0159] The determination module 303 is further configured to determine the workstation information corresponding to all abnormal static electricity wristbands according to the communication path information corresponding to each abnormal static electricity wristband.

[0160] It can be seen that this optional embodiment can screen out wristbands in abnormal states and determine the workstation information corresponding to the abnormal wristbands, which helps to subsequently locate the abnormal wristbands and / or corresponding employees according to the workstation information, helps to promptly resolve electrostatic risks, and improves the efficiency of electrostatic risk supervision.

[0161] In yet another optional embodiment, Figure 4 As shown, the device may also include:

[0162] The second judgment module 305 is used to judge whether any electrostatic wristband meets the condition for modifying the wristband configuration; when it is judged that the electrostatic wristband meets the condition for modifying the wristband configuration, a modification instruction corresponding to the condition for modifying the wristband configuration is sent to the electrostatic wristband, so that the electrostatic wristband modifies the configuration information of the electrostatic wristband according to the modification instruction; the configuration information includes communication path information and / or a time interval for sending feedback signals in time sharing.

[0163] Optionally, the status of the handband slave can be modified through the host computer (including the aggregation layer host and PC). Figure 3 As shown, its functions include: querying the master-slave channel address, modifying the master-slave system, modifying the master-slave address, modifying the time interval of the slave time-sharing transmission, etc.; it can be modified with one key after entering the required configuration, and after the modification, the parameters can be saved on the modified device through EEPROM or FLASH, which is convenient for unified management.

[0164] Optionally, the aggregation layer host can simultaneously receive commands from the PC, modify its own channel, address, reply delay, etc. according to the commands, and can also modify the bracelet slave through commands, making it convenient for the management end to manage the slaves at the lowest level. Optionally, the host computer can be written in QT, which can be quickly transplanted to different systems to facilitate different system operations.

[0165] It can be seen that this optional embodiment can send the modification information to the wristband when it is determined that the electrostatic wristband needs to modify the configuration information so that the wristband itself modifies the configuration information, which is helpful for adjusting the configuration of the wristband according to the actual application environment and improving the adaptability of the wristband to the use environment.

[0166] In yet another optional embodiment, Figure 4 As shown, the device may also include:

[0167] The generating module 306 is used to generate a workstation location map corresponding to each abnormal static electricity wristband according to the workstation information corresponding to each abnormal static electricity wristband after the determining module 303 determines the workstation information corresponding to all abnormal static electricity wristbands according to the communication path information corresponding to each abnormal static electricity wristband;

[0168] And, the acquisition module 302 is further used to obtain the employee portrait corresponding to the abnormal static electricity wristband;

[0169] And, the device also includes:

[0170] The first control module 307 is used to control the smart monitoring glasses to project the workstation location map and employee portrait map corresponding to all abnormal static electricity bracelets onto the retina of the static electricity monitoring personnel through harmless laser when it is detected that the static electricity monitoring personnel are wearing smart monitoring glasses.

[0171] It can be seen that this optional embodiment informs the electrostatic monitoring personnel of the workstation location map of the abnormal wristband and the corresponding employee portrait by projecting laser through monitoring glasses, which helps to improve the efficiency and accuracy of monitoring information transmission.

[0172] In yet another optional embodiment, Figure 4 As shown, each electrostatic wristband is provided with a light projection device; wherein the first judgment module 304 is also used to judge whether there is prompt information that needs to be prompted to the target employee when the target employee wears the target electrostatic wristband; when it is judged that there is prompt information, determine the target display area corresponding to the prompt information;

[0173] And, the device also includes:

[0174] The second control module 308 is used to control the light projection device of the target electrostatic wristband to project the prompt information to the target display area, so that the target employee can obtain the prompt information through the projected picture in the target display area.

[0175] It can be seen that when this optional embodiment determines that there is information that needs to remind employees, the prompt information will be projected to a designated area through a light projection device, which helps employees obtain prompt information through the projected content of the area, improves the efficiency of employees obtaining prompts in a timely manner, and improves the convenience of employees obtaining prompt information.

[0176] In yet another optional embodiment, Figure 4 As shown, the first determination module 304 determines whether there is prompt information that needs to be prompted to the target employee in the following manner:

[0177] Obtain a full-body image of the target employee at his / her workstation;

[0178] According to the full-body image of the target employee, segmenting the face area image of the target employee from the full-body image of the target employee, determining whether the target employee wears face protection equipment according to the face area image of the target employee, and when it is determined that the target employee does not wear face protection equipment, determining that there is prompt information that needs to prompt the target employee; or,

[0180] Based on the full-body image of the target employee, a torso area image of the target employee is segmented from the full-body image of the target employee, and based on the torso area image of the target employee, it is determined whether the target employee is wearing anti-static protective clothing. When it is determined that the target employee is not wearing anti-static protective clothing, it is determined that there is prompt information that needs to prompt the target employee; when it is determined that the target employee is wearing anti-static protective clothing, it is determined based on the torso area image of the target employee whether the zipper of the anti-static protective clothing of the target employee is located at a preset position. When it is determined that the zipper of the anti-static protective clothing of the target employee is not located at the preset position, it is determined that there is prompt information that needs to prompt the target employee.

[0181] It can be seen that this optional embodiment determines whether there is prompt information that needs to be prompted to the target employee by judging whether the employee is wearing protective equipment through facial images, judging whether the employee is wearing protective gloves through hand images, or judging whether the employee is wearing anti-static protective clothing through torso images, which helps to improve the accuracy and efficiency of determining whether there is prompt information that needs to be prompted to the target employee.
