Referring to Fig.1, a kind of structural block diagram of RFID attendance checking system embodiment of the invention is shown, can specifically include:

RFID reader, RFID transponder (that is, electronic tag) and computer system.

Wherein, RFID reader has antenna, can emit the radio wave energy of specific frequency.

The working principle of RFID attendance checking system is the radio wave energy that RFID reader emits a specific frequency by antenna Amount, is received by RFID transponder, so that RFID transponder is triggered, its internal data is launched in activation, then, RFID Reader passes through the data of antenna received in sequence RFID transponder, and the application program for being transmitted to computer system (can be this Invent the RFID Work attendance device of following embodiments) do corresponding processing.

Wherein, a RFID reader can be mating with multiple RFID transponders (n RFID transponder as shown in Figure 1) It uses.

In embodiments of the present invention, RFID reader may be mounted at an electronic equipment and (set referred to herein as low frequency triggering It is standby) on, which may be mounted at predeterminable area (such as the doorway region, such as classroom doorway in the classroom for attending class Ground, metope, on door etc.), wherein the predeterminable area is the student region necessary when entering classroom, also, the RFID The reader mark in the above-mentioned classroom of mark of uniqueness, i.e. device id are carried in reader.

And RFID transponder has been equipped in each student of school sessions, wherein the corresponding product of RFID transponder It can be the electronic product that Intelligent bracelet and/or electronic identity card for students etc. are convenient for user to carry.The RFID transponder of one student It has been pre-configured with the information such as the transponder india D, such as student number, identification card number for the unique identification pupilage.

In addition, Fig. 1 illustrates only the RFID reader in a classroom, still, in practical applications, each examined for course Diligent classroom can install the RFID reader of an embodiment of the present invention, and which is not described herein again.

In embodiments of the present invention, it after the low frequency for being mounted on classroom triggers device power-up starting, can send always First default frequency band signals (such as low frequency signal, such as 125k signal), the range of signals of the first default frequency band signals with It is positioned as within the scope of the pre-set radius in the center of circle where low frequency triggering equipment.

When student's bracelet is by within the scope of the pre-set radius, the 125k signal of low frequency triggering equipment can receive, from And the activation that is triggered, then bracelet sends bracelet ID (i.e. transponder india D) and the time t being activated and triggers equipment to low frequency；

Then, low frequency triggers equipment for bracelet ID (i.e. transponder india D) and time t and device id (i.e. Reader ID) Application program-i.e. the Work attendance device of the embodiment of the present invention being sent in computer system, application program determine after time t In the continuous period, the corresponding student of bracelet ID is the student to attend class in the classroom where the device id, is arranged the student's Which kind of checking-in state is checking-in state (be specifically arranged to and then need to be to belong to time break of attendance course before class according to time t The current checking-in state and subsequent low frequency of section or attendance course school session period and the student trigger equipment The no high-frequency signal for receiving bracelet determines, is detailed in the description of subsequent processes embodiment), notice low frequency triggering equipment is set Standby ID is sent to bracelet；

Wherein, the purpose that bracelet ID and activationary time t tremendously low frequency triggering equipment are sent after bracelet is activated is by applying Program determines whether the corresponding student of the bracelet is student that this classroom needs attendance.

Then, low frequency triggers equipment and device id is sent to bracelet, and bracelet can be periodical after receiving the device id Transmission second preset frequency band signals (such as high-frequency signal, such as 2.4G signal) to activating the low frequency of the bracelet to trigger equipment, Wherein, which carries bracelet ID and the device id received from low frequency triggering equipment；

Wherein, the purpose that the device id of oneself is sent to bracelet is that bracelet can be by the equipment by low frequency triggering equipment ID is carried in the high-frequency signal of transmission, so that low frequency triggering equipment can be sent according to the high-frequency signal judgement received Whether the bracelet of the high-frequency signal is the bracelet activated by oneself.

Then, after low frequency triggers the 2.4G signal that equipment receives bracelet, application program is reported to, by application program to this The checking-in state of the corresponding student of bracelet is configured.

Wherein, the frequency range of the default frequency band signals of first to illustrate here is lower than the second default frequency band signals, but at other In embodiment, it is also possible to the first default frequency band signals higher than the second default frequency band signals, the present invention does not limit this.

In embodiments of the present invention, after student enters classroom, the RFID Intelligent bracelet/electronic identity card for students worn can be with Bracelet ID is sent by the triggering equipment triggering of classroom doorway low frequency, and to low frequency triggering equipment, low frequency triggers equipment will by gateway Bracelet ID is transmitted to the Work attendance device of the embodiment of the present invention；Wherein, RFID Intelligent bracelet/electronic identity card for students triggers equipment by low frequency After triggering, can at preset timed intervals the period (such as 2 minutes) periodically send high-frequency signal to activate it low frequency trigger equipment；If Low frequency triggering equipment receives RFID Intelligent bracelet/electronic identity card for students high-frequency signal, then Work attendance device of the invention can be true The fixed student is in classroom, if bracelet passes through above-mentioned low frequency region, bracelet receives low frequency signal (wherein, when bracelet low frequency It is not receive low frequency signal when region except the range of signal of signal) then think that student enters and leaves doorway, then the present invention Embodiment is by combining the reception condition of high-frequency signal and low frequency signal that can accurately judge the attendance situation of student.

It should be noted that in all embodiments of the invention, RFID reader, which is interrupted, receives the transmission of RFID transponder High-frequency signal the case where can be divided into following two:

One: RFID transponder of situation is captured by other RFID readers, i.e., RFID transponder is by the RFID of other classes Reader activation trigger, so that the high-frequency signal that the RFID transponder is sent after being activated will not be again to original class RFID reader receives, and causes RFID reader to be interrupted and receives the high-frequency signal that RFID transponder is sent.

Two: RFID transponder of situation (i.e. linear distance) at a distance from the RFID reader for activating it is more than pre-determined distance (such as can be any one value between 10m~20m, including boundary value).

Preferably, which is greater than or equal to any position and the low frequency of classroom doorway region configuration in classroom and touches Send out the farthest linear distance between the position of equipment.

Therefore, when the low frequency triggering equipment that student's carrying bracelet passes through classroom doorway can be to the classroom after being activated Low frequency triggers equipment and sends high-frequency signal；After the student, which carries bracelet, goes out classroom, the low frequency in bracelet and the classroom triggers equipment Distance be more than pre-determined distance, and/or, when student is by the low frequency triggering equipment on other classroom doorways and the case where be activated Under, the low frequency triggering equipment in originally classroom can interrupt reception to the high-frequency signal of the bracelet.

Wherein, it should be noted that the scheme of the embodiment of the present invention is ignored after student goes out classroom, stands always in the classroom The case where doorway region.Under normal circumstances, student goes out behind classroom or leaves classroom and goes to other places, i.e., situation one or enters it His classroom, i.e. situation two.

Embodiment two

In conjunction with the embodiments one, referring to Fig. 2, show a kind of student attendance embodiment of the method based on RFID of the invention Flow chart of steps.

Before introducing flow chart shown in Fig. 2, the base that the Work attendance method of the embodiment of the present invention is related to is introduced first This concept and tables of data etc..

The Work attendance method of the embodiment of the present invention is when carrying out attendance to a class (i.e. target course), for the target course Define the period for attendance, that is, the second default attendance period, wherein the second default attendance period was understood that For course period (hereafter with course attendance period to illustrate), i.e. school session.

Optionally, which can also have the first default attendance period for attendance, this first default is examined The diligent period can be understood as period break (hereafter with attendance period break to illustrate), i.e., during break.

Specifically, when the end time point of such as first class is the break of t1, first class and the second class Between section be [t1, t2], the class period of the second class section be [t2, t3].Target course is the second class, then the of target course One default attendance period was [t4, t2], wherein t4 ∈ [t1, t2)；The default attendance period of the second of target course be [t2, T3], wherein at the beginning of the end time point t2 of the first default attendance period was the described second default attendance period Between point t2.

In other embodiments, when attendance rule is in upper the second predetermined time period t5 after class all not counting late (example In 5 minutes such as to attend class after starting, i.e. t5=5min), it is more than that second predetermined time period is then calculated and to be late, then target course First default attendance period can be [t4, t2+t5], and the second default attendance period was [t2+t5, t3].

In one example, the method for the embodiment of the present invention can be pre-configured with three tables of data to each attendance personnel, Respectively position record sheet, active record sheet, attendance record table.

Wherein, position record sheet, for recording the mark in the classroom that student attends class, such as 201 (assuming that one class of junior two).When When determining that low frequency triggering equipment receives high-frequency signal, using the ID in the classroom having in low frequency triggering equipment, to the position of the student Record sheet is set to be configured.

Active record sheet switches the time point of checking-in state for recording student.

Such as, however, it is determined that low frequency triggering equipment receives high-frequency signal, then the time for receiving high-frequency signal is arranged, when subsequent Between change, be state switching time point.

Attendance record table, for recording the current checking-in state of student, each student is in the corresponding course of position record sheet On checking-in state variation after, the method for the embodiment of the present invention can all switch to the checking-in state recorded in the table current Checking-in state, wherein the checking-in state recorded in the table may include following one: state of turning out for work, state of leaving early, late shape State, state absent from duty etc..

Before carrying out student attendance to target course, the method for the embodiment of the present invention can initialize the target course pair The above-mentioned of all attendance personnel (all students of the i.e. upper target course) answered is three tables of data, and the numerical value in table is complete Portion is assigned to empty (null)；

Above three table changes with the variation of the checking-in state of student.

Step 101, before being put at the beginning of the second default attendance period of target course, however, it is determined that RFID is read Device receives the second default frequency band signals of target RFID transponder, then by the corresponding target student of the target RFID transponder Checking-in state switch to the state of turning out for work；

Wherein, target RFID transponder can be any one RFID transponder shown in FIG. 1.The present embodiment and after All illustrate by taking student's bracelet as an example in continuous embodiment.

Specifically, the execution opportunity of the step 101 can be any one time point before school session starts, or It is a period (such as above-mentioned first default attendance period).Therefore, if target course the course attendance period At the beginning of in some time point or the first default attendance period before point (such as above-mentioned t2), the embodiment of the present invention Method determines that low frequency triggering equipment (i.e. RFID reader) of the target course receives the high-frequency signal from student's bracelet, then Checking-in state in the attendance record table of the corresponding target student of student's bracelet can be switched to the state of turning out for work.

Wherein, the application program of the embodiment of the present invention is determining whether RFID reader receives the high frequency of RFID transponder When signal, determining mode can be any one in the method for known technology or the following exploitation.

It in one example, can be by receiving (such as the device id of information entrained by high-frequency signal from RFID reader Determine whether the RFID reader receives the high-frequency signal of RFID transponder with bracelet ID).

Step 102, before being put at the beginning of the second default attendance period of target course, however, it is determined that RFID is read Device does not receive the second default frequency band signals of target RFID transponder, then by the corresponding target of the target RFID transponder Raw checking-in state switches to state absent from duty；

It is similar with the detailed description of step 101, when the application program of the embodiment of the present invention was determined in the course attendance period At the beginning of put before, then can be with when the low frequency of target course triggering equipment does not receive the high-frequency signal of student's bracelet The checking-in state of the corresponding target student of student's bracelet is switched to state absent from duty.

It should be noted that step 101 and step 102 execute sequence there is no specific, in the second default attendance time Before being put at the beginning of section, if a student of target course constantly passes in and out the classroom of the target course, above-mentioned step Rapid 101 and step 102 can be alternately performed, thus complete at the beginning of the course attendance period put before to student attendance Turn out for work between state and state absent from duty and constantly switches record.Wherein, in initial switching, empty shape of turning out for work will can be in State switches to the state of turning out for work or state absent from duty, and subsequent switching is constantly switched between the state of turning out for work and state absent from duty.

By means of step 101 and step 102, the method for the embodiment of the present invention can before course attendance starts, for Low frequency triggering equipment receives the high-frequency signal of which student's bracelet, and does not receive the high-frequency signal of which student's bracelet, The checking-in state of corresponding student is switched into the state of turning out for work or state absent from duty.

Step 101 and step 102 main function are that before course attendance starts, that is, system time reaches course attendance Before putting at the beginning of in period, (state of turning out for work, or state absent from duty) is initialized to the checking-in state of student, from And convenient for step 103 and step 104 determine student target checking-in state (such as state of turning out for work, state absent from duty, late state, It leaves early state etc.).

Although the execution opportunity of step 101 and step 102 may include any one before starting the course attendance period A time point or any one period, but the execution content of step 101 and step 102 with specifically using which execute when Machine is simultaneously unrelated, therefore, in order to avoid the duplicate contents of embodiment repeat, in subsequent processes embodiment, all with step 101 and step Rapid 102 execution opportunity is to carry out content related with step 101, step 102 for the above-mentioned first default attendance period Illustrate, the execution method of step 101 and step 102 and execution opportunity are above-mentioned first pre- under other unlisted execution opportunitys If the execution method of attendance period is similar, therefore no longer repeats one by one, refer to mutually.

Step 103, within the described second default attendance period of the target course, however, it is determined that the target RFID is answered The first default frequency band signals that device receives the RFID reader are answered, then is preset and is examined described second according to the target student The first checking-in state switched to for the last time before point at the beginning of the diligent period, by the checking-in state of the target student Switch to the second checking-in state；

Before the attendance of attending class of target course starts, i.e., (example before being put at the beginning of the second default attendance period Within any one time point, any one period-for example above-mentioned default first attendance period), if the present invention is implemented The application program of example determines that the target RFID transponder in step 101 and/or step 102, i.e. student's bracelet have received the mesh The low frequency signal for marking the low frequency triggering equipment of course, then illustrate that target student has passed through doorway region, it may be possible to it enters the classroom, May be classroom out, therefore, it is necessary to before combining target student to put at the beginning of the second default attendance period (such as In the default first attendance period) checking-in state (i.e. the first checking-in state) that is eventually switched to may be to turn out for work, be also likely to be Absence from duty, to determine this second checking-in state that will switch to of target student.

By at the beginning of the second default attendance period point start before the default first attendance period for into Row explanation, if in period break, the checking-in state of target student is eventually switched to the state of turning out for work, then illustrating that the student exists The case where classroom, then step 103 receives low frequency signal, has gone out classroom for the student again, and therefore, which is early Move back state, that is, the checking-in state of target student is switched into the state of leaving early from the state of turning out for work；

For another example, in period break, the checking-in state of target student is eventually switched to state absent from duty, then illustrating the student It does not all enter the classroom before course starts, then step 103 the case where receiving low frequency signal, enters classroom for the student, therefore, Second checking-in state is late state, that is, the checking-in state of target student is switched to late state from state absent from duty；

In addition, it is necessary to explanation, due in the course attendance period, student may be because a variety of causes (such as upper lavatory Institute makes a phone call, teacher is helped to take data etc.) classroom is repeatedly entered and left, to repeatedly determine that student's bracelet of the same student is received To the low frequency signal of low frequency triggering equipment, so, within the course attendance period, whenever the bracelet for determining primary target student Receive the target course low frequency triggering equipment low frequency signal, will the checking-in state to target student once cut It changes, therefore, which can constantly change.

Wherein, it is described whether the target RFID transponder receives is being determined for the application program of the embodiment of the present invention When the low frequency signal of RFID reader, determining mode can be any one in the method for known technology or the following exploitation.

In one example, application program can by from RFID reader receive bracelet ID, receive low frequency signal when Between (wherein, bracelet ID, receive low frequency signal time be to be sent to after being activated by RFID reader by target RFID transponder The RFID reader) determine whether target RFID transponder receives the low frequency signal of the RFID reader.

Step 104, the switching road according to the checking-in state of the target student within the described second default attendance period Diameter determines the target checking-in state of the target student；

Wherein, within the course attendance period, the checking-in state of target student can constantly be sent out according to disengaging classroom door Changing therefore can be according to the toggle path of checking-in state of the target student within the course attendance period, to determine this The final checking-in state of target student, i.e. target checking-in state.

Wherein, which, which can be, turn out for work-leave early-turns out for work, alternatively ,-be late-leaving early-absent from duty is late.

Embodiment can be divided into for the scene for the high-frequency signal that the low frequency triggering equipment of above-mentioned steps 101 receives bracelet Three and two kinds of scenes of example IV.

Embodiment three

On the basis of example 2, it when executing step 101, can be accomplished by the following way:

The scene of embodiment three are as follows: student first class after class, the second class attendance start before do not go out classroom, i.e., Without low frequency region, student's bracelet does not receive low frequency signal, which directly waits upper second class (i.e. target course), Under so such scene, after being entered the classroom due to the student in upper first class, bracelet has received low frequency signal, institute With, the second class before class, such as in period break, the bracelet of the student can also periodically send high-frequency signal, Hence, it can be determined that low frequency triggering equipment can receive the high-frequency signal, still, which can't receive low frequency signal And it is triggered again.So can be according to the bracelet ID carried in high-frequency signal, to determine that the bracelet belongs to upper target course Which student's, i.e. target student.And the checking-in state of target student is switched into the state of turning out for work, it here can be from the mesh The initial checking-in state (i.e. null) of mark course switches to the state of turning out for work.

Where it is determined whether receiving high-frequency signal, the method for determination of low frequency signal is referred to the specific of Fig. 2 embodiment Description, which is not described herein again.

In this way, in embodiments of the present invention, when target course and a upper class are in the same classroom, and student is upper complete After a upper class, not out classroom when, the method for the embodiment of the present invention still can be according to the course attendance period of target course At the beginning of receive only high-frequency signal before point, and the case where do not receive low frequency signal, and by the checking-in state of student It accurately is switched to the state of turning out for work, without being switched it to because low frequency signal is not received to state absent from duty, improves and examines Diligent accuracy.

Example IV

On the basis of example 2, it when executing step 101, can also be realized by following S21 and S22:

S21, before being put at the beginning of the second default attendance period of target course, however, it is determined that target RFID response Device receives the first default frequency band signals of RFID reader and determines that the RFID reader receives the target RFID and answers Answer the second default frequency band signals of device, then in the multiple students for determining the target course according to the described second default frequency band signals Target student corresponding with the target RFID transponder；

The checking-in state of the target student is switched to the state of turning out for work by S22.

The scene of example IV are as follows: student enters in the classroom of target course outside classroom by low frequency region, thus really Determine low frequency signal and the case where high-frequency signal all receives, and then the checking-in state of the corresponding target student of bracelet is switched to and is turned out for work State can be here from initial checking-in state (null) and switch to the state of turning out for work.

Specifically, student's bracelet is firstly received the low frequency signal of the low frequency triggering equipment of low frequency region and is triggered sharp Living, then, as described in Fig. 1 embodiment, which can be by bracelet ID or further comprise the time t for receiving low frequency signal Low frequency triggering equipment is sent jointly to, the application program of the embodiment of the present invention can trigger the received bracelet of equipment according to low frequency ID and time t determines that bracelet receives low frequency signal；

In addition, since bracelet is in classroom, bracelet can also periodically send high-frequency signal and (carry bracelet ID), hence, it can be determined that low frequency triggering equipment receives the high-frequency signal, so, it can be according to the hand carried in high-frequency signal Ring ID, to determine the bracelet belongs to which student of upper target course, i.e. target student.And by the attendance shape of target student State switches to the state of turning out for work, and here can be to switch to the state of turning out for work from the initial checking-in state (i.e. null) of the target course.

In this way, in embodiments of the present invention, when student attendance scene is the classroom that student enters target course outside classroom When interior scene, the method for the embodiment of the present invention can be by determining that bracelet receives low frequency signal and low frequency triggers equipment and receives The case where to high-frequency signal, and the checking-in state of student is accurately switched to the state of turning out for work, improve attendance accuracy.

Embodiment five

On the basis of example IV, when executing S21, it can be accomplished by the following way:

For example, within attendance period break of target course, when the checking-in state to student switches over, in determination After bracelet receives the low frequency signal of low frequency triggering equipment, bracelet for example can also be obtained from low frequency triggering equipment and receive low frequency The time point t of signal illustrates to have passed through low frequency region, i.e. classroom doorway in time point t student, but having no knowledge about the student is It enters the classroom still classroom out.It therefore, can be in time point t to the time of course attendance period at the beginning of point (such as t2) In section [t, t2], gone to judge whether low frequency triggering equipment can receive the bracelet according to preset period of time by application program The high-frequency signal of transmission can determine if so, illustrating that student is entered into classroom outside classroom and need to correspond to the bracelet The checking-in state of student switch to the state of turning out for work.

After if student goes out classroom, there is no the case where classroom doorway is hovered, therefore, between student's bracelet and the classroom Distance can be more than pre-determined distance and/or bracelet can trigger device activation by the low frequency in other classrooms, therefore, original classroom Low frequency triggering equipment can interrupt reception to the high-frequency signal that the bracelet is sent, lead to, originally classroom interior in the period [t, t2] Low frequency triggering equipment cannot receive the high-frequency signal of the bracelet according to preset period of time.

In this way, in embodiments of the present invention, after determining that bracelet receives low frequency signal before course attendance starts, Can also since the time point that bracelet receives low frequency signal up to course attendance before, monitor the low frequency triggering equipment Whether high-frequency signal from the bracelet is periodically received, if so, the corresponding student of the bracelet can be determined in course It does not go out after what attendance started advance into classroom, therefore, the checking-in state of the corresponding target student of the bracelet is switched to again It turns out for work state, improves attendance accuracy.

Embodiment six

On the basis of example IV, when executing S21, it can also be accomplished by the following way:

For example, within attendance period break of target course, if the application program of the embodiment of the present invention determines bracelet The low frequency signal for receiving low frequency triggering equipment then illustrates the corresponding student of the bracelet in disengaging classroom, then the bracelet is swashed After work, its bracelet ID can be sent to low frequency triggering equipment, then, the method for the embodiment of the present invention can be touched from the low frequency Hair equipment obtains the device id of bracelet mark and low frequency triggering equipment.

Wherein, for any one class journey, which its student to attend class has record in background data base in advance, Therefore, the low frequency for classroom installation of attending class has been pre-configured with for the target course for a target course, in database Trigger the device id of equipment, and the bracelet ID with the associated all students that attend class of the device id, therefore, the embodiment of the present invention Application program can be according to the incidence relation of the device id of the preconfigured target course and bracelet ID, to judge that the bracelet is The no legal bracelet for the target course, i.e., by searching for the incidence relation, if the bracelet ID and device id that obtain are above-mentioned Exist in incidence relation, it is determined that the corresponding student of the bracelet is the legal student to attend class in the classroom.

Wherein, after determining bracelet corresponding student not legal student, the application program of the embodiment of the present invention can be notified The low frequency triggers equipment and its device id is sent to the legal bracelet, and then, it is concurrent that legal bracelet can generate high-frequency signal It send, wherein the high-frequency signal carries device id and the bracelet ID of oneself received from low frequency triggering equipment.

Wherein, which can only be sent to the high-frequency signal its low frequency triggering equipment of activation, so, if this The application program of inventive embodiments determines that low frequency triggering equipment has received the high-frequency signal of the legal bracelet, then can basis Which student is corresponding with bracelet ID in multiple students of the bracelet ID carried in high-frequency signal to determine the target course Target student.And then the checking-in state of target student is switched into the state of turning out for work.

In embodiments of the present invention, after bracelet triggers device activation by low frequency, bracelet ID can be sent into tremendously low frequency Equipment is triggered, so that whether the student that the method for the embodiment of the present invention can judge to hold bracelet according to bracelet ID is low frequency touching Send out the legal student of the corresponding attendance course of equipment；Device id is sent to the conjunction by control low frequency triggering equipment in a case of yes Method bracelet allows legal bracelet that bracelet ID and device id are generated high-frequency signal and be sent to and its low frequency triggering is activated to set It is standby, and by low frequency triggering device forwards to the application program of the embodiment of the present invention, in this way, the application program of the embodiment of the present invention is just The checking-in state of the corresponding user of the legal bracelet can be switched over.

Implementation can be divided into for the scene for the high-frequency signal that the low frequency triggering equipment of above-mentioned steps 102 does not receive bracelet 9 two kinds of scenes of example seven and embodiment.

Embodiment seven

On the basis of example 2, it when executing step 102, can be realized by following S31 and S32:

S31, before being put at the beginning of the second default attendance period of target course, however, it is determined that target RFID response Device receives the first default frequency band signals of RFID reader and determines that the RFID reader does not receive the target RFID The default frequency band signals of the second of transponder, it is determined that in multiple students of the target course with the target RFID transponder pair The target student answered；

The checking-in state of the target student is switched to state absent from duty by S32.

The scene of embodiment seven are as follows: first class is finished class, after break, upper second class (target course).Student Classroom to be walked out after class in first class, that is, passes through low frequency region, student's bracelet receives low frequency signal, but in target course The student (before putting at the beginning of the i.e. second default attendance period) that attends class before attendance does not return after leaving classroom The classroom, distance of the bracelet apart from the classroom are more than pre-determined distance, alternatively, bracelet is swashed by the low frequency triggering equipment in other classrooms It is living, it, therefore, can should then low frequency triggering equipment will not receive the high-frequency signal of bracelet transmission under such scene The checking-in state of the corresponding student of bracelet switches to state absent from duty.

Wherein, when determining that whom the student is specifically, it can use any one method of known technology or the following exploitation Target student corresponding with the target RFID transponder in multiple students to determine the target course.

In the present embodiment, student's bracelet receives the low frequency signal of the low frequency triggering equipment of low frequency region and is triggered sharp After work, as described in Fig. 1 embodiment, student's bracelet can by bracelet ID or further comprise receive low frequency signal time t mono- It rises and is sent to low frequency triggering equipment, the application program of the embodiment of the present invention can trigger equipment from low frequency and obtain bracelet ID (or further comprise time t), and obtain the device id of low frequency triggering equipment, then, according to bracelet ID and device id come Determine the corresponding student of the bracelet whether be the target course legal student, i.e. target student.Specifically it is referred to implement Example six.

In this way, in embodiments of the present invention, when target course and a upper class are in the same classroom, and student is upper complete After a upper class, when walking out classroom, the method for the embodiment of the present invention is according to only reception in attendance period break of target course To low frequency signal, and the case where do not receive high-frequency signal, and student is accurately switched in the checking-in state of target course State absent from duty improves attendance accuracy.

Embodiment eight

On the basis of embodiment seven, when executing S31, it can also be accomplished by the following way:

For example, within attendance period break of target course, when the checking-in state to student switches over, in determination After bracelet receives the low frequency signal of low frequency triggering equipment, bracelet for example can also be obtained from low frequency triggering equipment and receive low frequency The time point t of signal illustrates to have passed through low frequency region, i.e. classroom doorway in time point t student, but having no knowledge about the student is It enters the classroom still classroom out.It therefore, can be in the time of the end time point (such as t2) of time point t to attendance period break In section [t, t2], gone to judge whether low frequency triggering equipment can receive the bracelet according to preset period of time by application program The high-frequency signal of transmission has left classroom, can determine and need the bracelet if it is not, then illustrating that student is walked out out of classroom The checking-in state of corresponding student switches to state absent from duty.

Because after going out classroom if it is student, there is no the case where classroom doorway is hovered, therefore, student's bracelet with should The distance between classroom can be more than that pre-determined distance and/or bracelet can trigger device activation by the low frequency in other classrooms, therefore, former The low frequency triggering equipment for coming classroom can interrupt reception to the high-frequency signal that the bracelet is sent, and cause within the period [t, t2], former The low frequency triggering equipment for coming classroom cannot receive the high-frequency signal of the bracelet according to preset period of time.

In this way, in embodiments of the present invention, after determining that bracelet receives low frequency signal before course attendance starts, Can also since the time point that bracelet receives low frequency signal up to course attendance before, monitor the low frequency triggering equipment Whether high-frequency signal from the bracelet is periodically received, if it is not, can then determine the corresponding student of the bracelet in course Attendance does not return classroom after going out before starting from classroom, therefore, by the checking-in state of the corresponding target student of the bracelet State absent from duty is switched to, attendance accuracy is improved.

In addition, it is necessary to explanation, after target student walks out the classroom of the target course, if by other courses Classroom low frequency region, then the bracelet of target student can by the low frequency in other classrooms trigger device activation, then target The low frequency triggering equipment of course then will be unable to receive the high-frequency signal of target student's bracelet.Because bracelet is only supported to sharp Can its living low frequency triggering equipment sends high-frequency signal, send high-frequency signal as trigger equipment to the low frequency, then depend on The application program of the embodiment of the present invention determine the bracelet whether be the low frequency triggering equipment legal bracelet.

Embodiment nine

As described in above-described embodiment two, within the course attendance period, whenever the bracelet for determining primary target student connects Receive the target course low frequency triggering equipment low frequency signal, will the checking-in state to target student once cut It changes, and specifically switches to which checking-in state, then (the i.e. described target student is in the course attendance time with the first checking-in state The checking-in state switched to for the last time before point at the beginning of section) it is related, so, whenever determining primary target student's Bracelet receives the low frequency signal of the low frequency triggering equipment of the target course, and the second checking-in state can all change.

Therefore, on the basis of example 2, execute step 103 it is described according to the target student described second The first checking-in state switched to for the last time before point at the beginning of the default attendance period, by examining for the target student When diligent state switches to the second checking-in state step, it can be accomplished by the following way:

Mode 1, if the first checking-in state of the target student is state of turning out for work and current checking-in state is also shape of turning out for work The checking-in state of the target student is then switched to the state of leaving early from the state of turning out for work by state；

That is, target student finally switches within such as attendance period break after step 101 and/or step 102 Checking-in state (i.e. the first checking-in state) extremely is to turn out for work state, then within the course attendance period, when student's hand has been determined When ring receives low frequency signal, the current checking-in state of the corresponding target student of student's bracelet is state of turning out for work, then due to Student's bracelet has received low frequency signal, illustrate that student has passed through low frequency region, so student into or out classroom, and due to working as Preceding checking-in state is therefore state of turning out for work illustrates that student is that classroom has been walked out out of classroom, student's bracelet can just receive low frequency Signal.So in this process, be at school during student it is outgoing, so, can by the checking-in state of target student from Current checking-in state (state of turning out for work) switches to the state of leaving early (i.e. the second checking-in state).

Mode 2, if the first checking-in state of the target student is state of turning out for work, current checking-in state is state of leaving early, The checking-in state of the target student is then switched into the state of turning out for work from the state of leaving early；

Wherein, after step 101 and/or step 102, target student most egress within such as attendance period break The checking-in state (i.e. the first checking-in state) shifted to is state of turning out for work, i.e., before class the student comes into classroom, then in class In the Cheng Kaoqin period, if current checking-in state is state of leaving early, illustrate that target student's school session passes through low frequency range Classroom has been walked out in domain, causes to be the state of leaving early now.And this step determines that student's bracelet receives low frequency signal, then explanation exists School session, student have been returned to classroom after going out.It therefore, can be by the checking-in state of target student from current checking-in state (the i.e. described state of leaving early) switches to the state of turning out for work.

1~mode of mode 2 in summary, if the first checking-in state be turn out for work state, if it is determined that bracelet receive it is low Frequency signal can then switch to the state of leaving early；If then repeatedly determining, bracelet receives low frequency signal, can be in the state of turning out for work and morning Move back cyclic switching between state.

Mode 3, if the first checking-in state of the target student is state absent from duty and current checking-in state is also shape absent from duty The checking-in state of the target student is then switched to late state from the state absent from duty by state；

That is, target student finally switches within such as attendance period break after step 101 and/or step 102 Checking-in state (i.e. the first checking-in state) extremely is state absent from duty, i.e., before class the student does not enter the classroom, then examining in course In the diligent period, when being determined that student's bracelet receives low frequency signal, the corresponding target student's of student's bracelet is currently examined Diligent state is state absent from duty.So since student's bracelet has received low frequency signal, illustrate that student has passed through low frequency region, so Student into or out classroom, and since current checking-in state is state absent from duty, illustrate that student is that religion has been come into out of classroom Room, so that student's bracelet receives low frequency signal.So in this process, be at school during first time of student enter religion Room, so, the checking-in state of target student can be switched to late state (i.e. second from current checking-in state (state absent from duty) Checking-in state).

Mode 4, if the first checking-in state of the target student is state absent from duty and current checking-in state is late shape The checking-in state of the target student is then switched to the state of leaving early from the late state by state；

Wherein, after step 101 and/or step 102, target student most egress within such as attendance period break The checking-in state (i.e. the first checking-in state) shifted to is state absent from duty, i.e., before class the student does not enter the classroom, then in course In the attendance period, if current checking-in state is late state, illustrate that target student's school session has come classroom, and Determine that student's bracelet receives low frequency signal in this step 103, that is, the bracelet passes through low frequency region, and target student has walked out religion Room.Therefore the checking-in state of target student can be switched into the state of leaving early from current checking-in state (the i.e. described late state) (i.e. the second checking-in state).Because student does not return after going out from classroom during at school.

Mode 5, if the first checking-in state of the target student is state absent from duty and current checking-in state is shape of leaving early The checking-in state of the target student is then switched to late state from the state of leaving early by state.

Wherein, after step 101 and/or step 102, target student is at the beginning of the second default attendance period Between put before, such as in attendance period break, the checking-in state (i.e. the first checking-in state) finally switched to is state absent from duty, I.e. before class the student does not enter the classroom, then within the course attendance period, if current checking-in state is state of leaving early, Illustrate that target student's school session has come classroom, but it passes through low frequency region and has walked out classroom, causes to leave early now State.And in this step 103, determine that student's bracelet receives low frequency signal, and the current checking-in state of target student is to leave early State then illustrates that the student enters classroom again through low frequency region, it is possible to by the checking-in state of target student from current Checking-in state (the i.e. described state of leaving early) switches to late state.Because during at school, student returns after going out from classroom again ?.

3~mode of mode 5 in summary, if the first checking-in state is state absent from duty, if it is determined that bracelet receive it is low Frequency signal can then switch to late state；If then repeatedly determining, bracelet receives low frequency signal, can be in late state and morning Move back cyclic switching between state.

In embodiments of the present invention, within the course attendance period of target course, only determine that student's bracelet receives Low frequency signal, so that it may be switched to for the last time before being put at the beginning of the course attendance period according to the target student The first checking-in state, the checking-in state of the target student is flexibly switched into the second checking-in state, wherein the second attendance State may include following one: state of leaving early, late state, state of turning out for work, can accurate judgement student whether classroom, whether Leave early, whether be late etc., prevent the generation of student's abnormal conditions.

Embodiment ten

On the basis of example 2, according to the target student at the beginning of the described second default attendance period Between the first checking-in state for switching to for the last time before point, the checking-in state of the target student is switched into the second attendance shape After state, can also include: according to the method for the embodiment of the present invention

I.e. during course attendance, after student switches a checking-in state, equipment can be triggered according to low frequency High-frequency signal whether is received to carry out secondary-confirmation to the checking-in state after switching in the first predetermined time period.

Within the course attendance period, after switching a checking-in state to target student, switching the attendance shape In the first predetermined time period after state, if the low frequency triggering equipment of the target course can receive target student's The high-frequency signal of bracelet then illustrates target student in classroom；On the contrary, illustrating that the bracelet of target student is low with the classroom The distance between frequency triggering equipment alreadys exceed pre-determined distance and/or the bracelet and triggers device activation by the low frequency in other classrooms, Therefore, secondary-confirmation and correction can be carried out to the checking-in state (i.e. the second checking-in state) after switching.

Embodiment 11

On the basis of embodiment nine, embodiment ten, execute it is described according to the RFID reader to the target First checking-in state and institute of the reception condition of the default frequency band signals of the second of RFID transponder and the target student State the second checking-in state, it is determined whether restore the checking-in state of the target student to nearest one from second checking-in state When the step of the checking-in state before secondary switching, it can be accomplished by the following way:

If the first checking-in state of the target student be turn out for work state, second checking-in state be leave early state and Determination is switching to the checking-in state of the target student in the first predetermined time period after the second checking-in state, described RFID reader receives the second default frequency band signals of the target RFID transponder, then by the attendance shape of the target student State switches to the state of turning out for work from the state of leaving early；

If the first checking-in state of the target student be turn out for work state, second checking-in state be turn out for work state and Determination is switching to the checking-in state of the target student in the first predetermined time period after the second checking-in state, described RFID reader does not receive the second default frequency band signals of the target RFID transponder, then by the attendance of the target student State switches to the state of leaving early from the state of turning out for work；

If the first checking-in state of the target student is state absent from duty, second checking-in state be late state and Determination is switching to the checking-in state of the target student in the first predetermined time period after the second checking-in state, described RFID reader does not receive the second default frequency band signals of the target RFID transponder, then by the attendance of the target student State switches to state absent from duty from the late state；

If the first checking-in state of the target student is state absent from duty, second checking-in state be state of leaving early and Determination is switching to the checking-in state of the target student in the first predetermined time period after the second checking-in state, described RFID reader receives the second default frequency band signals of the target RFID transponder, then by the attendance shape of the target student State switches to late state from the state of leaving early；

If the first checking-in state of the target student is state absent from duty, second checking-in state be late state and Determination is switching to the checking-in state of the target student in the first predetermined time period after the second checking-in state, described RFID reader does not receive the second default frequency band signals of the target RFID transponder, then by the attendance of the target student State switches to the state of leaving early from the late state.

1. not going out classroom, then student's state remains the state of turning out for work without low frequency region during after class；

2. passing in and out low frequency region repeatedly during after class but not going out classroom, then student's state keeps switching, eventually receives it It is modified to and turns out for work after high-frequency signal；

3. passing through low frequency region, i.e. classroom out after class, then student's state is switched to state absent from duty.

Example 2:

Lagged time point: 9:15am

1. if student's current state is that an absent from duty or upper class is left early.Low frequency region is passed through before current time 9:15am, It enters the classroom, then student's state becomes turning out for work；

2. if student's current state is that an absent from duty or upper class is left early.After current time 9:15am, under before the class pass through it is low Frequency domain is entered the classroom, then student's state becomes late；

3. after attendance, a upper class is left early, but the student of current time 9:15am attendance not yet, state is assigned: lacking It is diligent.

School session (after break attendance): 9:15am-9:55am

1. passing through low frequency in current slot 9:15am-9:55am if student's current state is normally to turn out for work/be late to turn out for work Region, i.e. classroom out, then student's state becomes leaving early；

2. low frequency range is passed through in current slot 9:15am-9:55am, that is, is entered the classroom if student's current state is absence from duty, Then student's state becomes late；

Wherein: if student passes in and out low frequency region repeatedly but leaves classroom, correcting student's state by two absolute rules.

If student is captured by other classroom furnitures and (triggers device activation by the low frequency in other classrooms) and location information It should not be inconsistent in region with student, then the attendance period is revised as absence from duty, course is revised as leaving early in the attendance period；

If student leaves after the certain distance of classroom (15m), periodical high-frequency signal (sending cycle 2min) can not be connect It receives, the backstage high-frequency signal renewal time and current time difference > 2min, then the checking-in state modification in attendance period break It is revised as leaving early for checking-in state absent from duty, in the course attendance period.

In summary, student checking-in state path that may be present:

It turn out for work-leave early-turns out for work；It is late-leaves early-is late；- be late-leaving early-absent from duty is late.
