Description

Intelligent attendance system and method based on block chain

Technical Field

The invention relates to the field of company attendance management service, in particular to an intelligent attendance system and method based on a block chain.

Background

In enterprise management, attendance is an indispensable link, and an attendance mode is formed by the initial manual roll call, the hand check-in, the current intelligent modes of card swiping input, fingerprint recording, face recognition, RFID induction, mobile phone application (such as nailing) positioning attendance and the like, and the current newer technical means is RFID induction attendance, so that nailing application is more convenient and wider.

The intelligent attendance system based on RFID is realized by enabling staff/working vehicles to respectively hold one induction chip, and realizing judgment of the passing direction of the card holder/vehicle in multiple directions by arranging a plurality of card readers at multiple positions, so that whether staff is on duty or away is identified, and finally, the attendance work of enterprises on teaching staff is completed.

The nail is a relatively universal enterprise management software and comprises an attendance function. The attendance range is set by an administrator, whether staff enters a work place or not is detected by means of the GPS positioning function of the mobile phone, and card punching can be clicked in the attendance range. In order to take care of the condition that the card is forgotten to be punched, the opportunity that the card is applied for a plurality of times per month can be set, the card can be applied for the card to be punched in a week when the card is missed, and the card is approved by a supervisor. Only the mobile terminal has the function of punching a card and checking work attendance, and the computer terminal cannot punch a card, so that the cheating action of punching a card by a computer of a remote operation unit can be stopped, but staff can still log in a nail by using another unusual mobile phone, the mobile phone is remained in the work unit's work attendance range, and other staff are required to punch the card instead of the point so as to achieve the aim of checking work attendance without going to work.

Fingerprint identification and face recognition are currently the most common attendance checking means, and the method can achieve high accuracy based on the uniqueness of the fingerprints and facial features of people. By means of modern high-performance computer processing, the application of face recognition can ensure high accuracy and realize high efficiency and rapidness, and has a good effect in a teaching class roll call scene.

These attendance techniques described above, while achieving strict and accurate management, still suffer from the following problems: 1. and the mechanical management is limited to time on-duty and off-duty, and cannot be remedied in a mode of early off-duty in the morning or late off-duty in the evening. 2. In the fixed mode, the card punching is specially returned to the original working point for the situation of temporary training to the headquarters of the company or other branches. 3. The flexibility is not enough, and staff going out to run business can not punch cards. 4. The fake loopholes exist, signatures or proxy signatures exist, the card swiping can be performed instead of swiping, and part of low-level face recognition can also be performed by using a photo.

Disclosure of Invention

Further, the server determines the attendance condition of the staff by:

if staff exceeding the preset value in the same department realizes attendance interaction, directly judging the whole staff of the whole department, generating marking data, and marking that all the staff of the department arrive on duty;

if the attendance checking interaction is realized among the staff of which the number does not exceed the preset value in the same department, judging that the staff is out of duty; and acquiring staff not realizing attendance checking and mutual authentication, and sending information not participating in the mutual authentication to an intelligent terminal of the staff.

Further, when the staff receives the information of not participating in the mutual evidence, the staff can choose to initiate voting and send voting feedback information to the server;

after receiving the voting feedback information, the server sends the voting information to the intelligent terminals of other staff realizing the attendance interaction of the same department as the staff, and judges whether the staff not realizing the attendance interaction arrives at the post or not according to the voting result.

Further, the server determines the attendance condition of the staff by:

presetting a parameter state value of whether the workload is oversaturated, if so, carrying out an oversaturated classified attendance mode, introducing a customer service state parameter of an external system (such as a queuing and calling system) to assist attendance, continuously changing the head queuing state of a customer service queue according to a preset rule (such as continuously going forward), presetting an attendance full member on duty, pushing a complaint link to staff on duty, and if staff not on duty exist, feeding back complaint conditions, and if no feedback exists in a preset time threshold, confirming that the full member is on duty.

Further, the acquired interaction information is file interaction information;

when the intelligent terminal detects the files sent by the intelligent terminals of other staff or the intelligent terminal sends the files to the intelligent terminals of other staff, the current time stamp and related intelligent terminal information are acquired, an information block is generated, and the attendance block chain is updated according to the information block.

Further, an access login port is formed in the server, and an administrator can access a website of the server in a network encryption mode to obtain blockchain data so as to trace the card punching condition of staff.

Further, a performance calculation module is arranged on the server and is used for obtaining interaction and communication times of staff according to the interaction information and calculating performance and salary of the staff according to the interaction and communication times.

The invention adopts another technical scheme that:

an intelligent attendance checking method based on a block chain comprises the following steps:

logging in information of an intelligent terminal capable of attendance interaction in advance;

when the intelligent terminal of the staff detects the interaction information, generating an attendance block chain according to the interaction information; the interaction information comprises file mutual transmission information and/or local area network information;

and storing the attendance block chain, and acquiring attendance conditions of all staff according to the attendance block chain.

Further, the interaction information is local area network information;

The beneficial effects of the invention are as follows: the invention records the interaction information among staff through the blockchain, judges the attendance situation according to the interaction information, provides a more flexible attendance mode, and avoids the existing inflexible attendance modes (such as nailing, fingerprint punching, face punching, RFID punching and the like) needing fixed positions.

As shown in fig. 1, this embodiment provides an intelligent attendance system based on a blockchain, including:

In this embodiment, a server is used as a central processing server, and attendance recorders are set in departments requiring attendance. And a system developed by the back end is deployed in the server to realize unified attendance data processing, and the front end provides various interfaces to be connected with the department recorder. The development application app is installed in a mobile phone (namely an intelligent terminal) of a user client, the app automatically runs in the background of the mobile phone, automatically establishes a local area network with a nearby user, realizes information docking, and is connected with a department recorder. When staff go to work, mutual induction is realized between mobile phone apps, on-duty mutual authentication is realized, when the staff reach 80% of the time at the stop point of going to work, mark data of the whole staff on duty is generated and uploaded to a server, and all the staff marked as departments arrive at the duty; if the number of the personnel who do not participate in the mutual authentication is not 80%, automatically generating a mark of lack of work, and sending a message to the mobile phone of the personnel who do not participate in the mutual authentication, namely that the attendance of the personnel is failed.

As an alternative embodiment, when the attendance of staff in the department fails, the staff who fails to complete the attendance can initiate a post vote to let the colleague select whether the staff arrives at the post, if the vote reaches a certain proportion preset value, the attendance is completed, if the vote does not reach the preset value but exceeds a certain time threshold value without overruling the vote, the attendance is completed, anonymous reporting can be performed in the department to start a checking mechanism, preset sanctions are performed on the staff who are not in charge or integrity sanctions are performed on the anonymous reporter, the credibility of the votes of the follow-up staff is reduced, and the like. Specifically, the person can initiate voting to the mobile phone of the person participating in mutual authentication, the mutual authentication personnel vote is used for determining whether the initiator successfully checks the attendance, if so, the initiator is added into a mutual authentication personnel queue, but the mutual authentication personnel queue does not have voting authority, the person can pass until the mutual authentication personnel queue reaches 80%, and if the person still does not pass, a list of absences personnel is generated and uploaded to a server. The attendance rules for the work-in are similar to this. The absenteeism personnel can also directly initiate the post approval to the supervisor, and the supervisor decides whether the supervisor completes the task on the same day so as to complete the attendance.

The most important difference between the system of the embodiment and the traditional attendance is that: when two staff mobile devices are close, a local area network (such as a local wireless wifi network or a Bluetooth network) is automatically established, and the staff confirmation of each other is completed. The beneficial effects of the system of this embodiment are: the complicated operation of staff is reduced through the investment of more intelligent equipment, and the working efficiency of a company is improved. The forced attendance check caused by dead plates is overcome, and staff can flexibly process work matters. The voting system is operated based on the harmonious relation among staff, so that friendly emotion communication among staff is promoted, and a good working environment is created.

As an alternative embodiment, the posts are subdivided into different types, which can also reduce the work load and pressure of the work attendance of the posts that are busy and in shortage. If only one person exists in one post, for example, the situation is that staff in the same department does not interact, and then the user directly initiates a response; for example, if there is only one person at the post of blood drawing, monitoring the change of the waiting queue of the patient at the gate of the blood drawing chamber as an interactive response, if the waiting queue does not move forward after exceeding the preset time (such as five minutes) in the working time, the post is out of duty, and if the queue moves forward all the time, the waiting queue does not need to be managed whether the waiting queue is out of duty or not; because the queue moves, it is stated that the employee is not out of duty, or someone is overriding the employee's job, it is also equivalent to the employee going to post if the overriding person does not initiate a complaint or report. And the information part is such that multiple people and few people can be alive, or the work load is a department with more sudden time, the interaction attendance mode can be adopted, and the mutual cohesive force and the work saturation degree of the departments can be better estimated.

As an alternative embodiment, blockchain based, except for attendance reconciliation, and recording the time each person was reconciled every day. In the follow-up compensation calculation of embedding the blockchain, the last time of each day is recorded, and when the number proportion of a person passing through each other in the same department or different posts according to the preset rules reaches the preset value or the preset rules, the attendance of the department is automatically maintained by the blockchain through writing in the blockchain. Therefore, the attendance checking mechanism is not based on the site and the place like the traditional attendance checking, but assumes that all people are on the site, and any person is on the site; in addition, the attendance mode can monitor the dynamic position of each person and the interaction condition between each person, and can perform artificial intelligence analysis in the later period to obtain more information; for example, the frequency of interactions and communications between departments is high, and the likelihood of communications between departments and personnel is the basis for subsequent analysis of department performance and enterprise performance.

The performance attendance and compensation calculation mechanism is embedded in the blockchain, and the mechanism linkage such as intelligent contract is carried out to evaluate various positive coefficients of each person, wherein the coefficients can comprise but are not limited to: 1) Integrity degree: the number of times of real arrival and attendance, malicious spurious complaints, others and the like can influence the integrity. 2) Degree of contribution: such as the number of times the time of day was authenticated to be proportional to the previous time, the time difference between the time of day the last time the day was authenticated to be accurate and the time of the next shift that should be on duty the day, the number of times the work on top of the help post, etc. 3) Friendliness: such as the number of co-workers not complaining about the same post and working on top of them, the number of interactions with co-workers at different posts and with the two departments performing effectively, etc. And carrying out automatic maintenance and automatic updating on the system algorithm according to the coefficients.

As an alternative embodiment, the server provides access rights to the outside with the website site, the server has multiple interface rules connected with the department's recorder, receives the attendance record of the department's recorder, and the administrator can access the server website through network encryption to obtain the data.

As an alternative embodiment, the same post relationships between employees are pre-established and maintained by the manager of each department post. The manager has certain authority, and the managers of all the subareas have the capability of carrying out information communication, so that the maintenance and temporary change of the working positions of the working points of the subordinate personnel are realized.

As an optional embodiment, each employee does not need a fixed mode to check in, and when the employee works at home, the employee can transmit the completed work task to a supervisor or an upper supervisor or even an informed co-worker at the same position through a network to initiate an attendance request, and the supervisor or the upper supervisor completes work confirmation and attendance; or the manager checks the normal attendance list of the department preset time in advance, and automatically sends a reminder to the person who is checked in for reminding and confirming when the attendance time is up.

In summary, the attendance system of the embodiment also has the following advantages and beneficial effects:

(1) The attendance checking operation is convenient, the staff is not required to operate manually, and the attendance checking authentication is automatically realized.

(2) The system can realize inspiration management and form a mechanism of department self-management based on the block chain, and the internal attendance of the department can be traced, so that the post work of staff can be properly mobilized.

(3) Based on the blockchain, staff can schedule work more flexibly; and with rules, employees can reconcile conflicts between personal transactions and corporate work; the staff can form friendly and harmonious atmosphere. Based on the attendance checking system, the relationship among staff can be more consistent, the attendance checking mode can be embodied to have more personal taste and more temperature.

As shown in fig. 2, the embodiment further provides an intelligent attendance checking method based on a blockchain, which includes the following steps:

s1, logging in information of an intelligent terminal capable of attendance interaction in advance;

s2, when the intelligent terminal of the staff detects the interaction information, generating an attendance block chain according to the interaction information; the interaction information comprises file mutual transmission information and/or local area network information;

and S3, storing the attendance block chain, and acquiring attendance conditions of all staff according to the attendance block chain.

Further as an optional implementation manner, the interaction information is local area network information;

The intelligent attendance method based on the block chain has a corresponding relation with the intelligent attendance system based on the block chain, so that the intelligent attendance method based on the block chain has the same functions and beneficial effects as the intelligent attendance system based on the block chain.
