Embodiments of the present application will be described below with reference to the accompanying drawings.
The following explains an application scenario of the embodiment of the present application:
fig. 1 is an application scenario diagram of a timing method for attendance devices according to an embodiment of the present application, as shown in fig. 1, for a large-scale enterprise or organization, multiple attendance devices 110 are generally required to check attendance of an employee, and 4 devices are taken as an example in fig. 1, and the employee can check attendance by means of fingerprints, human faces, employee cards, and the like. The accuracy of the local time of the attendance device 110 is determined by the accuracy of the operating frequency of the crystal oscillator of the attendance device 110, and due to the influences of temperature, product quality and the like, the time characteristics of different crystal oscillators are inconsistent, and the time of the attendance devices 110 is not synchronized, so that the time calibration of the attendance devices 110 is required to make the local time of the attendance devices 110 consistent.
In the prior art, two common timing methods are adopted, the first method is to perform timing on each attendance device 110 manually and regularly by a worker, and the timeliness and the accuracy are poor. The second method is performed through a standard time corrector 120 of the internet, each attendance device 110 needs to be accessed to the internet, local time calibration is performed based on the time of the standard time corrector, and the attendance device is accessed to the internet, so that the risk of data leakage of the attendance device 110 exists, and the security is poor.
In order to improve the timing safety of the attendance device 110, an embodiment of the present application provides a timing method of the attendance device, and the main concept thereof is as follows: the method comprises the steps that time calibration and synchronization of each attendance device in the local area network are achieved based on active communication among a plurality of attendance devices through the local area network, specifically, one attendance device serves as a timing initiator, time calibration requests are initiated to the rest attendance devices, accordingly, calibration time is determined based on local time and deviation values of each attendance device, and calibration and synchronization of the local time of each attendance device are achieved through the calibration time.
Fig. 2 is a flowchart of a timing method of an attendance device according to an embodiment of the present application. The time calibration method for the attendance device can be executed by any attendance device in a local area network, such as a first attendance device, as shown in fig. 2, and the time calibration method for the attendance device provided by this embodiment includes the following steps:
step S201, sending the time calibration request to each second attendance device through the local area network.
The attendance device is used for carrying out employee attendance, and in some embodiments, the attendance device also becomes an attendance device.
Specifically, according to a fixed period, any one of the multiple attendance devices is used as a first attendance device, and a time calibration request is actively sent to the other attendance devices, namely, the second attendance devices, through the local area network.
Specifically, one attendance device may be randomly selected as the first attendance device, i.e., as the sender of the time alignment request.
Specifically, each attendance device may periodically initiate a time calibration request, and send the time calibration request to each second attendance device through the local area network. The second attendance device takes the first attendance device which initiates the time calibration request as the first attendance device.
During one time or one round of time calibration, only one attendance device in a plurality of attendance devices in the same local area network is used as a first attendance device to initiate time calibration requests to the rest attendance devices.
Step S202, obtaining response data sent by each second attendance device, where the response data of the second attendance device includes a current local time and a current deviation value of the second attendance device.
The current local time is the current time or the local time corresponding to the current period. The current deviation value is used to describe the degree of deviation of the local time from the calibration time at the last time calibration, i.e. the degree of deviation of the last local time from the last calibration time.
In some embodiments, the current degree of deviation is a ratio of a last calibration time to a last local time.
In some embodiments, the current degree of deviation is the difference between the last calibration time and the last local time.
Specifically, when each second attendance device receives a time calibration request, the current local time of the second attendance device is acquired based on the time calibration request, the stored latest deviation value, that is, the current deviation value is used, response data or a response message is generated based on the current local time and the current deviation value, and the response data corresponding to the current time calibration request is sent to the first attendance device.
Step S203, determining the current calibration time according to the current local time and the current deviation value of each attendance device.
Wherein, each equipment of attendance includes first equipment of attendance and each second equipment of attendance.
Specifically, the first attendance device may analyze response data sent by each second attendance device, so as to obtain a current local time and a current deviation value of each second attendance device. Before, simultaneously with or after the first attendance device sends the time calibration request to each second attendance device via the local area network, the first attendance device is further configured to read the current local time of the first attendance device and the current deviation value.
Specifically, the current local time of each attendance device may be screened according to the current deviation value of each attendance device, for example, the current local time of each attendance device whose current deviation value exceeds the preset range is deleted, and the current calibration time is determined based on the average value of the remaining current local times of each attendance device.
Optionally, determining the current calibration time according to the current local time of each attendance device and the current deviation value, including:
determining the current weight coefficient of each attendance device according to the current deviation value of each attendance device; and determining the current calibration time according to the current weight coefficient of each attendance device and the current local time of each attendance device.
In some embodiments, the greater the absolute value of the difference between the current departure value of the attendance device and 1, the smaller the current weighting factor of the attendance device.
In some embodiments, the weighting system may bias the values into a negative correlation relationship.
In some embodiments, the current weighting factor for the attendance devices may be determined from the distribution of the current offset values for each attendance device.
Specifically, the current calibration time may be determined according to a product of a current weighting factor of each attendance device and the current local time.
Step S204, calibrating the current local time of the first attendance device based on the current calibration time, and sending the current calibration time to each second attendance device so as to calibrate the current local time of each second attendance device based on the current calibration time.
Specifically, after the current calibration time is determined, the first attendance device sends the current calibration time to each second attendance device, so that each attendance device performs current local time calibration based on the current calibration time, and the time of each attendance device in the local area network is synchronized.
Specifically, each attendance device calibrates the current local time based on the current calibration time, so as to check attendance based on the calibrated local time.
The time correction method for the attendance device provided by the embodiment of the application is used for a plurality of attendance devices in the same local area network, the local area network is used, the first attendance device sends a time correction request to the rest of the attendance devices, the second attendance devices send time correction requests, further, based on the current local time and the current deviation value in response data sent by the second attendance devices, the current correction time is determined, and the current local time correction of the attendance devices in the local area network is realized based on the current correction time, so that the time synchronization and the correction of the attendance devices are realized, the attendance accuracy is improved, compared with the time correction mode based on the internet, the safety of employee data stored in the attendance devices is improved, and the data leakage is avoided.
Fig. 3 is a flowchart of a timing method for an attendance device according to another embodiment of the present application, where the timing method for an attendance device according to this embodiment is further detailed in step S203 on the basis of the embodiment shown in fig. 2, and a step of adding a deviation value update after step S203, as shown in fig. 3, the timing method for an attendance device according to this embodiment may include the following steps:
step S301, sending the time calibration request to each second attendance device through the local area network.
The second attendance device is the other attendance device except the first attendance device in the plurality of attendance devices in the local area network.
Step S302, acquiring response data sent by each second attendance device.
Wherein the response data of the second attendance device comprises a current local time of the second attendance device and a current deviation value.
Step S303, determining the number of times of repetition of the current local time of each attendance device according to the current local time of each attendance device.
The number of times of repetition of the current local time is used for describing the number of times that a certain current local time appears in the current local time of each attendance device.
Specifically, after the first attendance device obtains the current local time of each attendance device, the first attendance device may count the occurrence frequency of each current local time, so as to obtain the repetition frequency of the current local time of each attendance device.
In some embodiments, the first attendance device may further sort the current local time of each attendance device from early to late or from small to large based on the current local time, and determine the number of repetitions of the current local time of each attendance device based on a result of the sorting.
Specifically, if the difference value of the current local times of the two attendance devices is smaller than the preset time difference, the current local times of the two attendance devices are determined to be repeated.
Wherein, the preset time difference can be 0.1s, 0.3s, 0.5s or other smaller values.
Step S304, determining the current weight coefficient of each attendance device according to the current local time repetition times and the current deviation value of each attendance device.
In some embodiments, the weight factor is positively correlated with the number of repetitions.
Optionally, determining a current weight coefficient of each attendance device according to the current local time repetition number and the current deviation value of each attendance device, including:
determining the current weight coefficient of each attendance device according to the repetition times of the current local time of each attendance device, the current deviation value and a preset relational expression; wherein, the preset relational expression is as follows:

is a constant coefficient;
is composed of
At the first moment
Repetition of local time of individual attendance devicesThe number of times;
is composed of
At the first moment
An offset value of the local time of the respective attendance device.
In some embodiments, in order to improve the accuracy of the calibration time, after the current local time of each attendance device is obtained, the response data of each attendance device is sorted based on the current local time, the response data of each attendance device with the current local time ranking beyond a preset interval, that is, the current local time and the current deviation value, are deleted, and the current calibration time is determined based on the current local time and the current deviation value of each attendance device with the current local time ranking within the preset interval. In the above formula
It indicates the number of each attendance device ranked outside the preset interval at the current local time.
Wherein, the preset interval can be 10% to 90%. I.e. removing the response data of the attendance device for the highest ranked 10% and the lowest ranked 10% of the current local time.
Optionally, the method further includes: and saving the current local time of the first attendance device.
Furthermore, each attendance device can also save the current local time so as to facilitate the maintenance of the attendance device.
Specifically, after the current local time is obtained, the current local time needs to be stored to a preset position by each attendance device, the first attendance device or the second attendance device, so as to perform device maintenance and data maintenance based on each local time.
Step S305, determining a current calibration time according to the current weight coefficient of each attendance device and the current local time of each attendance device.
In particular, the current calibration time
The expression of (a) is:
wherein the content of the first and second substances,
is composed of
At the first moment
The local time of the respective attendance device.
Step S306, calibrating the current local time of the first attendance device based on the current calibration time, and sending the current calibration time to each second attendance device so as to calibrate the current local time of each second attendance device based on the current calibration time.
Step S307, determining a new deviation value according to the current calibration time and the current local time of the first attendance device, so as to update the current deviation value of the first attendance device.
Specifically, for the next time calibration, the current deviation value of each attendance device needs to be updated, and each attendance device recalculates the next deviation value based on the received or determined current calibration time and the current local time.
In some embodiments, the first
The expression for the next or new deviation value of the counter attendance device is:
when receiving a time alignment request sent by the next first attendance device, the attendance device generates response data for the time alignment request based on the next deviation value or the new current deviation value and the current local time for the next or next round of time alignment.
