[0067] It should be understood that the specific embodiments described herein are merely intended to explain the technical solutions of the present application, and are not intended to limit the present application.

[0068] In order to better understand the technical solutions of the present application, the following will be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0069] The main solution of the embodiment of the present application is: the electrostatic protection circuit includes: a metal sheet connecting plug, an electrostatic discharge circuit, an electrostatic sampling circuit and a microcontroller; the metal sheet connecting plug is respectively connected with the metal sheet, the electrostatic discharge circuit and the electrostatic sampling circuit; the electrostatic sampling circuit includes a voltage dividing circuit and a conditioning circuit U10, the voltage dividing circuit is respectively connected with the metal sheet connecting plug and the conditioning circuit; the microcontroller is respectively connected with the electrostatic sampling circuit and the electrostatic discharge circuit in communication, for analog-digital conversion of the output voltage of the conditioning circuit to obtain the electrostatic voltage, and for controlling the electrostatic discharge circuit to be turned on or turned off.

[0070] Electrostatic is harmful to human health, and can also cause harm to the electronic circuit of the electronic product in production testing. In order to prevent the harm caused by human body static electricity, it is often necessary to measure the static electricity of the operator and release the static electricity during the production testing process. In the related art, the static electricity measuring device includes a contact type measuring device and a non-contact type measuring device. The contact type measuring device measures the voltage of the human body to the ground through a probe. The measurement principle is to measure the capacitance of the human body to the ground through an RC circuit, and to calculate the charge quantity and the static electricity. The non-contact type measuring device can realize high-resolution electrostatic imaging through FEG-OFET technology, and detect the static charge distribution through an induced electric field.

[0071] Among them, the RC loop sampling method of the contact type measuring device needs a certain charging / discharging time (usually tens to hundreds of milliseconds) to complete a sampling, and the impact current in the contact moment may introduce errors; the circuit and algorithm of the non-contact type measuring device are complex, and have very high hardware requirements for switches, ADCs, timing control and microprocessors, and complex algorithms need to be written to process the sampling data, to calculate the time constant or to perform integral operation.

[0072] The electrostatic discharge device includes a grounded electrostatic discharge device and a non-grounded electrostatic discharge device. The grounded electrostatic discharge device controls the human body static electricity to be discharged to the ground at a constant speed by touching the surface of a metal ball, through the built-in passive circuit system control; the non-grounded electrostatic discharge device captures and neutralizes the electric charge through the conductive ion network of Electragel ion gel, without grounding, or forms a conductive path by plating a copper layer on the surface of the metal fiber, and efficiently dissipates the electric charge.

[0073] However, the electrostatic measurement device and the electrostatic discharge device in the related art are often separate, that is, the electrostatic measurement and the electrostatic discharge are independently performed, and the operator cannot ensure whether the corresponding equipment meets the operation requirements after the electrostatic discharge, causing the charged operation of the corresponding equipment when the electrostatic discharge is insufficient to cause damage to the equipment.

[0074] Therefore, how to improve the accuracy and reliability of the electrostatic discharge is a problem to be solved at present.

[0075] The application provides a solution, which connects the metal sheet to the electrostatic discharge circuit and the electrostatic sampling circuit through the metal sheet connection plug, converts the electric signal of the electrostatic sampling circuit into an analog signal through the microcontroller, and obtains the electrostatic voltage, so that the operator can obtain the electrostatic voltage of the operator in real time through the electrostatic discharge circuit, accurately judge whether the electrostatic discharge of the current operator is in place, and reduce the situation of charged operation of the corresponding equipment when the electrostatic discharge is insufficient, thereby improving the accuracy and reliability of the electrostatic discharge.

[0076] Based on this, the application embodiment provides an electrostatic protection circuit, which refers to Figure 1 , Figure 1 is a circuit schematic diagram of an embodiment of the electrostatic protection circuit of the application.

[0077] In this embodiment, the electrostatic protection circuit includes a metal sheet connection plug CN2, an electrostatic discharge circuit, an electrostatic sampling circuit, and a microcontroller. The metal sheet connection plug is electrically connected to the metal sheet, the electrostatic discharge circuit, and the electrostatic sampling circuit.

[0078] The electrostatic sampling circuit includes a voltage dividing circuit and a conditioning circuit U10, and the voltage dividing circuit is electrically connected to the metal sheet connection plug and the conditioning circuit.

[0079] The microcontroller is in communication connection with the electrostatic sampling circuit and the electrostatic discharge circuit, is used for converting the output voltage of the conditioning circuit into an analog signal to obtain the electrostatic voltage, and controls the electrostatic discharge circuit to be turned on or turned off.

[0080] In a feasible implementation manner, as Figure 1As shown, the voltage dividing circuit includes a first voltage dividing resistor R27 and a second voltage dividing resistor R39, the resistance value of the first voltage dividing resistor R27 is greater than the resistance value of the second voltage dividing resistor R39; the output end of the metal sheet connecting plug is electrically connected with the first voltage dividing resistor R27, the connecting point between the first voltage dividing resistor R27 and the second voltage dividing resistor R39 is electrically connected with the conditioning circuit U10, and the second voltage dividing resistor R39 is grounded.

[0081] In the embodiment of the present application, the voltage dividing circuit of "metal sheet connecting plug CN2-first voltage dividing resistor R27-second voltage dividing resistor R39-ground" can be formed, the first voltage dividing resistor R27 is a large resistor, for example, the resistance value of the first voltage dividing resistor R27 is 999MΩ, 500MΩ, etc., and the resistance value of the second voltage dividing resistor R39 is 200kΩ, 100kΩ, 50kΩ, so as to divide the human body static voltage through the first voltage dividing resistor R27, so that the voltage of the second voltage dividing resistor R39 is small, that is, the voltage of the second voltage dividing resistor R39 can be converted from digital to analog through the analog-to-digital conversion module of the microcontroller.

[0082] The connecting point between the first voltage dividing resistor R27 and the second voltage dividing resistor R39 is electrically connected with the conditioning circuit U10, so as to input the voltage division of the second voltage dividing resistor R39 to the conditioning circuit U10, and the voltage division of the second voltage dividing resistor R39 is conditioned through the conditioning circuit U10, for example, impedance conversion and voltage lifting, and then the output voltage of the conditioning circuit is input to the ADC module of the microprocessor for analog-to-digital conversion to obtain the static voltage, that is, the current static voltage of the operator can be obtained, and the measurement of the human body static voltage is realized.

[0083] Further, in a possible implementation manner, as shown in Figure 1 As shown, the static electricity discharge circuit includes a MOS tube Q1 and a triode Q2.

[0084] The drain D of the MOS tube Q1 is electrically connected with the output end of the metal sheet connecting plug through a current limiting resistor R24, the source S of the MOS tube Q1 is grounded, and the gate G of the MOS tube Q1 is grounded through a discharge resistor R36.

[0085] The collector C of the triode Q2 is electrically connected with the gate G of the MOS tube Q1 through a second current limiting resistor R30, and the collector C is electrically connected with the power supply through a first conversion resistor R25; the base B of the triode Q2 is electrically connected with the microprocessor through a third current limiting resistor R33, and the emitter E of the triode Q2 is grounded.

[0086] In the embodiment, the MOS tube Q1 is a high-voltage MOS switch, the metal sheet connection plug output end is electrically connected to the drain D of the MOS tube Q1 through the current limiting resistor R24, the gate G of the MOS tube Q1 is grounded through the discharge resistor R36, and the source S of the MOS tube Q1 is directly grounded. When the MOS tube Q1 is turned on, a discharge path is formed from the metal sheet connection plug output end, the drain D of the MOS tube Q1, the source S of the MOS tube Q1, the discharge resistor R36, and the ground. At this time, if the tester touches the metal sheet, the human body static electricity can be discharged.

[0087] The collector C of the triode Q2 is electrically connected to the gate G of the MOS tube Q1 through the second current limiting resistor R30, and the collector C is electrically connected to the power supply through the first conversion resistor R25. The base B of the triode Q2 is electrically connected to the microprocessor through the third current limiting resistor R33, that is, the base B is electrically connected to the IO interface of the microcontroller. The triode Q2 is controlled by the IO interface of the microcontroller to perform level conversion, thereby controlling the turn-on and turn-off of the MOS tube Q1, and realizing the effect of controlling the turn-on and turn-off of the MOS tube Q1 through the triode Q2.

[0088] It should be noted that the MOS tube Q1 can be replaced by a high-voltage relay.

[0089] Further, in a feasible implementation manner, as shown in Figure 1 The static electricity discharge circuit further includes a diode U11, one end of the diode U11 is electrically connected to the source S of the MOS tube Q1, and the other end is electrically connected to the drain D of the MOS tube Q1. The base of the triode Q2 is grounded through the second conversion resistor R37.

[0090] In the embodiment, the diode U11 is arranged between the source S and the drain D of the MOS tube Q1 to protect the MOS tube Q1 from high voltage through the diode U11, thereby improving the reliability of the MOS tube Q1.

[0091] It should be noted that the voltage dividing circuit further includes a diode D2, one end of the diode D2 is electrically connected to the connection point between the first voltage dividing resistor R27 and the second voltage dividing resistor R39, and the other end is grounded. The diode D2 is arranged at both ends of the second voltage dividing resistor R39 to protect the second voltage dividing resistor R39 from high voltage through the diode U11, thereby improving the reliability of the second voltage dividing resistor R39.

[0092] In a feasible implementation manner, the microcontroller controls the static electricity discharge circuit to be turned on or turned off based on the static electricity voltage, or when a turn-on instruction or a turn-off instruction is received, the microcontroller controls the static electricity discharge circuit to be turned on or turned off.

[0093] In the embodiment of the present application, when the microcontroller detects the static voltage, if the static voltage is greater than the preset voltage of the operating device, the microcontroller can control the static discharge circuit to be turned on, or if the static voltage is less than or equal to the preset voltage of the operating device, the microcontroller can control the static discharge circuit to be turned off, so that the operator can automatically discharge the static voltage when measuring the human body static voltage. The preset voltage can be reasonably set according to the safety static voltage corresponding to the operating device, and the preset voltage is less than the safety static voltage, for example, the preset voltage = 0.5 * safety static voltage.

[0094] In the embodiment, a static discharge trigger button or the like can be provided to trigger the static discharge instruction, or the corresponding static discharge instruction can be triggered by a metal sheet. The static discharge instruction can include a turn-on instruction or a turn-off instruction. When the turn-on instruction or the turn-off instruction is received, the microcontroller controls the static discharge circuit to be turned on or turned off. For example, when the operator is measuring the human body static voltage, the microcontroller can light up the corresponding indicator lamp based on the current static voltage or the voltage range current to which the current static voltage belongs. The operator can trigger the turn-on instruction or the turn-off instruction according to the indicator lamp. When the static voltage is greater than the preset voltage of the operating device, a red indicator lamp can be lit up, that is, the circuit between the red indicator lamp and the power supply is turned on. When the static voltage is less than or equal to the preset voltage of the operating device, a green indicator lamp can be lit up, that is, the circuit between the green indicator lamp and the power supply is turned on.

[0095] In a feasible implementation, the microcontroller lights up the corresponding indicator lamp based on the current static voltage.

[0096] When the current static voltage is less than the preset voltage of the operating device corresponding to the static protection circuit, the microcontroller outputs a prompt information of completed static discharge.

[0097] In the embodiment of the present application, the static protection circuit is also provided with at least one indicator lamp. When the current static voltage of the operator is detected, the microcontroller lights up the corresponding indicator lamp based on the current static voltage or the voltage range current to which the current static voltage belongs. For example, when the static voltage is greater than the preset voltage of the operating device, a red indicator lamp can be lit up, that is, the circuit between the red indicator lamp and the power supply is turned on. When the static voltage is less than or equal to the preset voltage of the operating device, a green indicator lamp can be lit up, that is, the circuit between the green indicator lamp and the power supply is turned on.

[0098] Meanwhile, when the current static voltage is less than the preset voltage of the operating device corresponding to the static protection circuit, the microcontroller outputs a prompt information of completed static discharge to prompt the operator that the current static discharge has been completed.

[0099] It should be noted that in other implementations, a buzzer can also be arranged in the electrostatic protection circuit, and the microcontroller can control the buzzer to output different voice information based on different electrostatic voltages, for example, when the electrostatic voltage is greater than a preset voltage of the operating device, the buzzer is controlled to output voice information with a large volume, or to output voice information for electrostatic discharge, and when the electrostatic voltage is less than or equal to the preset voltage, the buzzer is controlled to output voice information with a small volume, or to output voice information that the electrostatic discharge has been completed.

[0100] In a possible implementation, the metal sheet is provided with a fingerprint detection module, which is in communication connection with a host computer corresponding to the electrostatic protection circuit.

[0101] In addition, the electrostatic protection circuit further comprises an iris recognition module and / or a face recognition module, which are in communication connection with the host computer.

[0102] In the embodiments of the present application, the fingerprint information of the operator can be detected by the fingerprint detection module, the iris information of the operator can be detected by the iris recognition module, and the face recognition information of the operator can be detected by the face recognition module, so as to identify the identity of the operator through the fingerprint information, the iris information and / or the face recognition information, to determine the identity information of the operator, and to improve the operation accuracy and safety of the operating device.

[0103] In the embodiments of the present application, the metal sheet is connected to the electrostatic discharge circuit and the electrostatic sampling circuit through the metal sheet connection plug, and the microcontroller is used to perform analog-to-digital conversion on the electrical signal of the electrostatic sampling circuit to obtain the electrostatic voltage, so that when the operator discharges electrostatic through the electrostatic discharge circuit, the microcontroller can obtain the electrostatic voltage of the operator in real time, to accurately determine whether the electrostatic discharge of the current operator is in place, to reduce the situation of operating the device while being electrified due to insufficient electrostatic discharge, and to improve the accuracy and reliability of electrostatic discharge.

[0104] Compared with the measurement of electrostatic voltage by using an RC circuit, the error caused by the impact current of the RC circuit can be avoided, and the real-time measurement of electrostatic voltage can be performed, thereby improving the detection efficiency of electrostatic voltage. Compared with the non-contact measurement device, the circuit structure of the voltage dividing circuit is simple and the detection process is simple, thereby improving the detection efficiency of electrostatic voltage.

[0105] Based on this, the embodiments of the present application provide a method for operating personnel, which is described with reference to Figure 2 , Figure 2 The flowchart of an embodiment of the electrostatic protection method of the present application is shown.

[0106] In the embodiment, the electrostatic protection method comprises steps S110-S130:

[0107] In step S110, the biometric information of the operator is acquired from the biometric module of the electrostatic protection circuit, wherein the biometric module comprises a fingerprint detection module, an iris recognition module and / or a face recognition module.

[0108] In step S120, the biometric information is matched with the preset biometric information in the white list, and whether the operator has the operation permission of the operation device corresponding to the electrostatic protection circuit is determined based on the matching result.

[0109] In step S130, if the operator has the operation permission and the current electrostatic voltage of the operator is less than the preset safety voltage, the operation authorization of the operation device is performed on the operator, and the prompt information of the authorization is output.

[0110] In the embodiment, the electrostatic protection circuit is provided with a biometric module, which comprises a fingerprint detection module, an iris recognition module and / or a face recognition module. Thus, when the operator releases electrostatic by using the electrostatic protection circuit, the fingerprint information, iris information or face recognition information of the operator can be acquired by the fingerprint detection module, the iris recognition module and / or the face recognition module. Specifically, the fingerprint information, iris information or face recognition information of the operator can be acquired by the electrostatic protection circuit or the host computer corresponding to the electrostatic protection circuit. In the embodiment, the host computer is used to acquire the biometric information.

[0111] It should be noted that the preset biometric information corresponding to the white list of the operator can be pre-stored in the host computer. The preset biometric information can correspond to the biometric module. The white list can be pre-set according to the operation device. The operator in the white list is the user who has the operation permission of the operation device.

[0112] After the biometric information is acquired, the biometric information is matched with the preset biometric information in the white list to determine whether the biometric information exists in the preset biometric information. If the biometric information exists in the preset biometric information, it is determined that the matching result is a matching success, otherwise, the matching result is a matching failure.

[0113] It can be understood that the matching of the biometric information can be the matching of the fingerprint information and the preset fingerprint information, the matching of the iris information and the preset iris information, the matching of the face recognition information and the preset face recognition information, or can include at least two of the above matching.

[0114] After the matching result is obtained, it is determined whether the operator has the operation permission of the operation device corresponding to the electrostatic protection circuit based on the matching result. If the matching result is a matching success, it is determined that the operator has the operation permission of the corresponding operation device. At this time, the current electrostatic voltage of the operator is obtained. When the current electrostatic voltage is less than or equal to the preset safety voltage, that is, when the electrostatic discharge of the operator is completed, the operation authorization of the operation device is performed on the operator, and the authorized prompt information is output. By performing the operation authorization according to the biological recognition information after the electrostatic discharge is completed, the operator can operate the operation device only after the electrostatic discharge is completed, and the safety of the operation device is further improved.

[0115] In a feasible implementation, after step S130, the electrostatic protection method can further include steps S140-S160.

[0116] In step S140, the authorized duration corresponding to the operator is accumulated.

[0117] In step S150, when the authorized duration reaches a preset duration, it is determined whether there is a static discharge operation corresponding to the operator within the preset duration.

[0118] In step S160, if there is no static discharge operation corresponding to the operator within the preset duration, the operation authorization of the corresponding device is closed, and the static discharge prompt information is output.

[0119] In the embodiment of the application, when the operation authorization of the operation device is performed on the operator, the authorized duration corresponding to the operator is accumulated, so as to accumulate the duration after each electrostatic discharge of each operator in real time. At the same time, it is determined whether the authorized duration reaches a preset duration. The preset duration can be reasonably set, for example, the preset duration is 1 minute. If the operator does not perform electrostatic discharge again within the preset duration, the electrostatic voltage of the operator before the operation can be greater than the preset safety voltage.

[0120] When the authorized duration reaches the preset duration, it is determined whether there is a static discharge operation corresponding to the operator within the preset duration. It should be noted that when the user performs electrostatic discharge again, the corresponding static discharge operation can be detected. At this time, the authorized duration corresponding to the operator is cleared.

[0121] If there is no discharge operation corresponding to the operator within the preset time, that is, the operator does not perform static discharge again after the last static discharge reaches the preset time, and the current static voltage of the operator is greater than the preset safety voltage, the operation authorization of the corresponding equipment is closed at this time, and a static discharge prompt information is output to prompt the operator to perform static discharge again. At the same time, the authorization is closed to prevent the operator from performing live operation on the operation equipment, and the safety of the operation equipment is further improved.

[0122] In a feasible implementation, the static protection method can further include steps S210-S230:

[0123] In step S210, the first body mass index and the first static voltage of each operator corresponding to the biological recognition information are acquired.

[0124] In step S220, the first average static voltage corresponding to each first body mass index is determined based on the first static voltage and the first body mass index.

[0125] In step S230, the first broken line graph is generated based on the first body mass index and the first average static voltage.

[0126] In the embodiment of the application, when each operator performs static discharge, the height information and the weight information of the operator are acquired at the same time as the biological recognition information, and the first body mass index of the operator is calculated based on the height information and the weight information, that is, the first body mass index = weight information (kg) / height information (m) 2. At the same time, the first static voltage of the operator is acquired, which can be the maximum static voltage collected by the static sampling circuit of the static protection circuit, so as to obtain the first body mass index and the first static voltage of the operator with different body characteristics.

[0127] Then, the static voltage corresponding to each first body mass index is determined based on the first body mass index and the first static voltage, and the first average static voltage corresponding to each first body mass index is calculated based on the static voltage corresponding to each first body mass index, so as to obtain the average static voltage of each operator with the same body mass index.

[0128] After the first average static voltage is acquired, the first broken line graph is generated based on the first body mass index and the first average static voltage, as shown in Figure 3 .

[0129] In a feasible implementation, the static protection method can further include steps S310-S330:

[0130] In step S310, the total discharge time of each electrostatic protection circuit in different regions and the number of discharging personnel corresponding to each total discharge time are obtained respectively.

[0131] In step S320, the average discharge time corresponding to each region is determined based on the total discharge time and the number of discharging personnel.

[0132] In step S330, a second line chart is generated based on the average discharge time corresponding to each region.

[0133] In the embodiment, when each operator performs electrostatic discharge, the discharge time of the current electrostatic discharge can be counted, for example, by determining the discharge time of the current electrostatic discharge through the duration of the conduction of the MOS tube Q1 controlled by the microcontroller in the electrostatic protection circuit, and then accumulating the total discharge time and the number of discharging personnel of the electrostatic protection circuit.

[0134] When the electrostatic protection circuit is deployed in multiple regions, the total discharge time of each electrostatic protection circuit in different regions and the number of discharging personnel corresponding to each total discharge time are obtained respectively. Based on the total discharge time and the number of discharging personnel, the average discharge time corresponding to each region is determined. Specifically, for each region, the average discharge time = the sum of the total discharge time of all electrostatic protection circuits in the region / the sum of the number of discharging personnel of all electrostatic protection circuits in the region.

[0135] After obtaining the average discharge time, a second line chart is generated based on the average discharge time corresponding to each region, as shown in Figure 4 . Figure 4 The line chart of the average discharge time, since the average discharge time in different regions is different, therefore, for enterprises, it can deploy the electrostatic protection circuit corresponding to the operating equipment according to the second line chart, so as to deploy the operating equipment in the region with smaller average discharge time as much as possible, that is, the second line chart can provide a reference for investment site selection.

[0136] In a feasible implementation, the electrostatic protection method can further include steps S410-S430:

[0137] In step S410, the second body mass index and the electrostatic discharge time of each operator corresponding to each biometric information are obtained.

[0138] In step S420, the average electrostatic discharge time corresponding to each second body mass index is determined based on the second body mass index and the electrostatic discharge time.

[0139] In step S430, a third line chart is generated based on the average electrostatic discharge time corresponding to each second body mass index.

[0140] In this embodiment, when each operator performs electrostatic discharge, their height and weight information are acquired simultaneously with their biometric information. A second body mass index (BMI) is calculated based on this information. Also, the electrostatic discharge time is acquired, for example, by controlling the duration of conduction of the MOSFET Q1 in the electrostatic discharge protection circuit via a microcontroller. The biometric information may include biometric information from different operators in different regions.

[0141] Next, based on the second body mass index in the electrostatic discharge time, the electrostatic discharge time corresponding to each second body mass index is determined, and the average electrostatic discharge time corresponding to each second body mass index is calculated based on the electrostatic discharge time corresponding to each second body mass index.

[0142] After obtaining the average electrostatic discharge time, a third line graph is generated based on the average electrostatic discharge time corresponding to the second body mass index, as shown below. Figure 5 As shown.

[0143] In one feasible implementation, the electrostatic discharge protection method may further include steps S510-S530:

[0144] Step S510: Obtain the second electrostatic voltage and environmental humidity information of the operator corresponding to each biometric information;

[0145] Step S520: Based on the second electrostatic voltage and the ambient humidity information, determine the second average electrostatic voltage corresponding to each ambient humidity range;

[0146] Step S530: Based on the second average electrostatic voltage and the ambient humidity range, generate a fourth line graph.

[0147] In this embodiment of the application, when each operator performs electrostatic discharge, the second electrostatic voltage of the operator is acquired at the same time as the biometric information is acquired. The second electrostatic voltage can be the maximum electrostatic voltage collected by the electrostatic sampling circuit of the electrostatic protection circuit. At the same time, the current ambient humidity information can also be acquired through the humidity sensor, thereby obtaining multiple maximum electrostatic voltages corresponding to each ambient humidity information.

[0148] Next, based on the second electrostatic voltage and the ambient humidity information, the second average electrostatic voltage corresponding to each ambient humidity range is determined. Specifically, the ambient humidity range mentioned in each ambient humidity information is determined, and based on the second electrostatic voltage corresponding to each ambient humidity information in each ambient humidity range, the second average electrostatic voltage corresponding to that ambient humidity range is calculated.

[0149] After obtaining the second average electrostatic voltage, a fourth line graph is generated based on the second average electrostatic voltage and the ambient humidity range, as shown below. Figure 6 As shown, through Figure 6 The relationship between the average electrostatic voltage and the ambient humidity range allows for dynamic adjustment of the ambient humidity of the operating equipment corresponding to the electrostatic protection circuit, as needed.

[0150] In one feasible implementation, the electrostatic discharge protection method may further include steps S610 to S630:

[0151] Step S610: Obtain the third electrostatic voltage and ambient temperature information of the operator corresponding to each biometric information;

[0152] Step S620: Based on the third electrostatic voltage and ambient temperature information, determine the third average electrostatic voltage corresponding to each ambient temperature range;

[0153] Step S630: Based on the third average electrostatic voltage and the ambient temperature range, generate a fifth line graph.

[0154] In this embodiment of the application, when each operator performs electrostatic discharge, while acquiring biometric information, the operator's third electrostatic voltage is also acquired. This third electrostatic voltage can be the maximum electrostatic voltage collected by the electrostatic sampling circuit of the electrostatic protection circuit. At the same time, the current ambient temperature information can also be acquired through a temperature sensor, thereby obtaining multiple maximum electrostatic voltages corresponding to each ambient temperature information.

[0155] Next, based on the third electrostatic voltage and ambient temperature information, the third average electrostatic voltage corresponding to each ambient temperature range is determined. Specifically, the ambient temperature range mentioned in each ambient temperature information is determined, and based on the third electrostatic voltage corresponding to each ambient temperature information in each ambient temperature range, the third average electrostatic voltage corresponding to that ambient temperature range is calculated.

[0156] After obtaining the third average electrostatic voltage, a fifth line graph is generated based on the third average electrostatic voltage and the ambient temperature range, as shown below. Figure 7 As shown, through Figure 7 The relationship between the average electrostatic voltage and the ambient temperature range allows for dynamic adjustment of the ambient temperature of the operating equipment corresponding to the electrostatic protection circuit, as needed.

[0157] It should be noted that for each operator, the static electricity release time and the equipment operation time (machine use time) of the operator can also be counted. Specifically, when the operator releases static electricity, the on time of the triode Q2 in the static electricity protection circuit (the control time of the microcontroller) is taken as the static electricity release time, and the machine use time of the corresponding operating equipment is obtained, which can be the operation time of the operator each time the equipment is operated, and a record table of the static electricity release time and the equipment operation time of the operator is generated, as shown in Table 1.

[0158] Table 1: Static electricity release time and equipment operation time record table

[0159]

[0160] When the operation authorization is problematic, the static electricity release time and the equipment operation time can also be used to determine whether the operator has violated the rules by not releasing static electricity. For example, if the static electricity release time and the equipment operation time in Table 1 differ by more than 1 minute, it is considered a violation.

[0161] Additionally, it should be noted that for multiple operators, the number of times each operator releases static electricity and the number of times each operator operates equipment within a period of time can also be counted, and a corresponding record table can be generated as an employee work efficiency statistical table, as shown in Table 2.

[0162] Table 2: Employee work efficiency statistical table

[0163]

[0164] Through Table 2, the number of times an operator releases static electricity and the number of times the operator operates equipment can be compared. If they are not equal, there is a violation. Table 2 can be used for excellent employee ranking, violation monitoring, employee work efficiency evaluation, and statistical data of operating equipment production, etc.
