Embodiment
Below in conjunction with attached drawing, embodiments of the present invention is further illustrated.
As shown in Figure 1, the method and device for making Train number recognition label change sending mode at work in the present invention is real
Apply in example, the method for its Train number recognition label conversion sending mode is as follows：
Step S11 receives activation signal, obtains present mode value of statistical indicant：In this step, train is by being provided with read-write
The region of device, reader send activation signal, and the Train number recognition electronic tag on rail vehicle receives activation signal
It is activated, start-up operation is powered on by resting state.When electronic tag is started to work, specified memory is read first
Take, obtain the mode flags in designated memory, obtain mode flags value.
Step S12 sends data in the first setting time according to the corresponding sending mode of present mode value of statistical indicant：At this
In step, the electronic tag for obtaining mode flags value enters corresponding sending mode according to the mode flags value, in the first setting
By the data that sending mode transmission is set to above-mentioned reader in time.That is, electronic tag will be to being stored in the mark
Mode flags position in label is judged, and enters different sending modes according to judging result, sends different data.
If the mode flags value obtained is " A "（First mode value of statistical indicant, can be by the binary system of a bit or multiple bit
Data represent）, then the label enter the first sending mode and send the data that are previously set.In this case, the electronics mark
Label can only send the generation label card number being previously set（That is the data of first generation car number identification system requirement）.In this implementation
In example, above-mentioned generation label card number includes the use of the 128bits data FSK coded formats on lorry and Locomotive RFID
The goods of 10kbps data transmission rates, locomotive card number data；Further include using the 128bits data on two-way locomotive and on car
The two-shipper car of FM0 coded format 40kbps data transmission rates, car card number data, and the relevant data of other rain models.
Certainly, above-mentioned generation label card number is written and stored in advance in above-mentioned electronic tag.In addition, in this step,
The electronic tag sends above-mentioned generation label card number in the form of frames.Specifically, the electronic tag is by above-mentioned generation mark
Label card number data are put into a data frame, then the data sending is gone out.In the present embodiment, in said one data frame only
Place a generation label card number.Meanwhile this frame including generation label card number that the electronic tag is sent is
Have a certain number of, frame very little may cause reader reception bad；And too many frame be likely to cause it is temporal
Delay.So in this step, the number that first setting time sends it data is set to be any limitation as.The electronics mark
Label continuously transmit N number of data frame for including generation label card number in the first setting time.What N was certainly previously set
One fixed value, its value can be chosen after being considered according to actual conditions, for example, can be chosen between 1-20.
If mode flags value is " B "（Second mode value of statistical indicant, can be by the binary data table of a bit or multiple bit
Show, its numerical value is different from above-mentioned first mode value of statistical indicant）, then electronic tag enter the second sending mode, send it is being previously set,
The data of increase setting data on the basis of above-mentioned first sending mode sends data（This pattern is typically second generation license number
The pattern that the car number identification system of identifying system or other upgrade versions uses）.In this case, label can only be sent sets in advance
Two fixed generation label card numbers.In the present embodiment, above-mentioned two generations label card number is except including the above-mentioned electronic tag
Train card number data outside, other specify informations, such as car inspection and repair information etc. can also be included.Certainly, above-mentioned two generations mark
Signing card number data is written and stored in advance in above-mentioned electronic tag.In this step, the wireless electronic tag is with frame
Form sends above-mentioned two generations label card number, and specifically, which is put into one by above-mentioned two generations label card number
In a data frame, then the data sending gone out.In the present embodiment, a two generation labels are only placed in said one data frame
Card number data.This frame including two generation label card numbers that the electronic tag is sent is that have a certain number of, frame very little
Reader reception may be caused bad；And too many frame is likely to cause temporal delay.So in this step,
The wireless electronic tag continuously transmits the M data frames for including two generation label card numbers.Certainly be previously set one of M
Fixed value, its value can be chosen after being considered according to actual conditions, for example, can be chosen between 1-20.Equally
Ground, data sending in this case are also limited in the first setting time.
In the present embodiment, one of them only occurs on the same time in above-mentioned two situations；Meanwhile for label and
Speech, the first situation（The pattern or the first sending mode that i.e. first generation car number identification system uses）It is default setting.
Step S13, which enters, intercepts state, and external command is received in the second setting time：In this step, above-mentioned electronics
Label has sent data in the first setting time, and into state is intercepted, it is the second setting time that this, which intercepts state maintenance time, uses
It is the instruction that external reader is sent in general in receiving external command.That is, the electronic tag is intercepting state
Under, stop sending any data, start to receive the instruction for being sent to the electronic tag.These usual instructions are by installed in ground
On reader（Or ground receiving equipment）Send out.In this step, the duration for intercepting state is to have to
Ask, if the duration is too short, possibly can not receive the instruction of reader transmission；If the time is too long, it will cause when
Between on delay.Its time T is a variable value, its value can be chosen after being considered according to actual conditions, for example,
It can be chosen according to different instruction length, under normal conditions time T values between 500us-10ms.In addition, in this reality
Apply in example, the length of time T can also choose a fixed value according to special circumstances.It may be arranged as in setting time knot
Beam is intercepted, as soon as but if receiving instruction within the time, then it can not wait and reach the setting time and terminate to intercept state.
In short, it can be adjusted according to actual conditions, to ensure to receive instruction and cause the too long of time to prolong
Late.
Step S14 receive instruction it is no, if not, return to step S11；If so, perform next step.In this step, to being
It is no to receive instruction and judged, typically carried out in the case where above-mentioned second setting time reaches or have been received by instruction
's.
Step S15 whether mode switch instruction, if so, jump to step S17, otherwise, perform next step.In this step
In rapid, since mode switch instruction is included according to certain tactic command code and operand, and its command code is unique.
Therefore, as long as the received instruction of docking is parsed, if obtained command code is the behaviour for the mode switch instruction being previously set
Make code, it is possible to which it is mode switch instruction to judge the instruction.Meanwhile in the present embodiment, the operand of mode switch instruction is
Send the current pattern for receiving data of the reader of the instruction（For example, the license number after first generation car number identification system or upgrading
Identifying system）.
Step S16 execute instructions：In this step, since the instruction received is in addition to above-mentioned mode switch instruction
Other instructions, so, electronic tag performs the instruction, for example, by writing data to above-mentioned nothing according to the content obtained after parsing
Line label is configured or the instruction of parameter setting etc..After having performed this step, return to step S11.
Step S17 takes out the operand of analog-to-digital conversion instruction, and designated memory is stored in as present mode value of statistical indicant：
In this step, the operand in above-mentioned mode switch instruction is obtained, and be written into electronic tag and substitute in designated memory
Current mode flags value.After having performed this step, return to step S11.That is, after having performed this step, the electronics mark
The present mode value of statistical indicant of label has been changed, meanwhile, return to step S11, be ready for sending the value of statistical indicant changed by this be directed toward or
Corresponding data.The mode of these data sendings can also change.For generally, electronic tag receives pattern upgrading and refers to
After order, electronic tag will change memory in mode flags value, when in memory mode flags value change after, electronic tag
Completion pattern updating operation, i.e., into two generation label read-only status.In the present embodiment, it can set to work as and be stored in electronic tag
In mode flags position after " B " is made into from " A ", the electronic tag in next electrification reset, keep mode flags value set
" B " is set to, which will not enter back into generation label read-only status and return to generation label card number, and be directly entered two
Two generation label card numbers are returned to for label read-only status, such case is adapted to reader upgrading and completes and need only to mark
Label upgrading.The mode flags value of label is still default " A " when can also be set to power on next time, and such case adapts to
Not yet completed in reader upgrading, i.e., there may be a generation and two generation Train number recognitions feelings mixed in together for the reader in roadside
Condition.Therefore, under normal circumstances, all it is that the mode flags position of electronic tag is changed to " B " into row mode updating operation by " A "；When
So, also can be according to practical situations, it is allowed to which the mode flags position of label is arranged to " A " by " B ".
In the present embodiment, above-mentioned mode switch instruction is provided in what the reader on railway side was sent.Fig. 2 is shown
Reader sends the step of pattern dress changes instruction, including：
Step S21 receives the data that electronic tag is sent：In this step, which enters working status, opens and reads
Device power amplifier is write, sends radiofrequency field, starts to receive data.The reader receives the number sent into the electronic tag of its sphere of action
According to.The data that reader receives that wireless electronic tag is sent in the present embodiment can be generation label card number, can also
It is two generation label card numbers.
Step S22 is still to receive data no：In this step, above-mentioned reader judges whether it still receives number
According to, if so, represent that data are also being sent, return to step S21；If it is not, then represent that above-mentioned electronic tag has sent number
According into state of intercepting, therefore performing step S23.
If reader is not received by the data of electronic tag transmission, at this moment the electronic tag has three kinds of situations, the
A kind of situation is that state is intercepted in wireless electronic tag entrance, at this moment reader sending mode upgrade command, the wireless electron mark
The mode flags position that label will change in memory；The second situation is that the wireless electronic tag is still within the read-only shape of generation label
State, reader receive error, and reader sending mode upgrade command, the electronic tag will be ignored at this time；The third situation is
Label（The rail vehicle of the label is really installed）Reader radio frequency place is left, reader sending mode upgrading at this time refers to
Order, the electronic tag will be unable to receive pattern upgrade command.
The data that step S23 is received meet no with current read-write device pattern, such as meet, and perform step S24；It is not inconsistent such as
Close, perform step S25, in this step, reader will dock received data and be judged, the data for judging to receive are one
For label card number or two generation label card numbers, while compared with this reader present mode, judge whether it meets.
For example, the pattern of current read-write device is two generation label card numbers, and electronic tag is the pattern of generation car number identification system, then
The received data of reader will require received data less than it, in this way, reader is by comparing the data volume of setting and connecing
Received data volume can be obtained by the data that receive whether the conclusion met with the pattern of current read-write device.
Step S24 sends the instruction of setting：In this step, since label mode is consistent with reader/writer mode, do not deposit
Upgrading or it is compatible the problem of, it is not necessary to send mode switch instruction.So reader searches whether what other needs were sent
Instruction, if any sending the instruction.
Step S25 rock mechanisms conversion instruction is simultaneously sent：In this step, it is necessary to which sending mode conversion instruction is to electronics mark
Label, make its upgrading or compatible reader, for this reason, it may be necessary to obtain the setting pattern of current read-write device（I.e. corresponding to electronic tag
First sending mode or the second sending mode）, formed and sent mould of the mode flags value as operand is set using current read-write device
Formula conversion instruction.
In the present embodiment, after reader sending mode conversion instruction, there may be three kinds of situations for label：The first feelings
Condition is that the electronic tag receives label after pattern upgrade command and rewrites mode flags value in memory block, and reader returns at this time
Step S21 can receive the first sending mode of electronic tag transmission（That is first generation car number identification system）Or second send
Pattern（Car number identification system i.e. after the second generation or upgrading）Corresponding data；The second situation is that the electronic tag is not correct
Pattern upgrade command is received, which will continue to send the data of its original sending mode, at this time reader
Return to step S21 can receive the data of electronic tag transmission；The third situation is that electronic tag leaves reader radio frequency
Place, at this moment reader return to step S21 can receive the data that next wireless electronic tag is sent.
Fig. 3 is shown in the present embodiment to the rail vehicle under electronic tag upgrade case and wireless electronic tag, read-write
The position view of device.Its course of work is as follows：A wireless electronic tag is set on each rail vehicle, rail vehicle is mutual
Connection, when radio frequency place of the train by reader, the wireless electronic tag that is loaded on rail vehicle is by order into studying in
Write the radio frequency place of device.In figure 3, if on TagA（Wireless electronic tag on a rail vehicle）In mould
When formula flag bit is " B ", when TagA enters the radio frequency place of reader, TagA will send two generation label card numbers, read-write
Device can receive two generation label card numbers of TagA transmissions, it is not necessary to sending mode upgrade command, but can be according to actual conditions
Send other instructions in addition to pattern upgrade command；When if on the mode flags position in TagA being " A ", when TagA enters
During the radio frequency place of reader, TagA will send generation label card number.When reader starts to be connected to the storage of TagA transmissions
After generation label card number in TagA, reader waits TagA to enter and intercepts state stopping transmission generation label card number
According to reader sending mode upgrade command at this time.After pattern upgrade command is sent, if there is data return, there are three kinds
Situation, the first situation are TagB（Wireless electronic tag on another rail vehicle）Have not been entered into penetrating for reader
Frequency place, TagA are successfully received pattern upgrade command, send two generation label datas in two generation label read-only status, connect at this time
Two generation label datas can be received by receiving data；The second situation is TagB（Wireless electron on another rail vehicle
Label）The radio frequency place of reader is had not been entered into, TagA has not been able to be successfully received pattern upgrade command, still in generation mark
Sign read-only status and send generation label data；The third situation be due to train running speed quickly, TagA has already been through reading
The radio frequency place of device is write, TagB is sent after entering the radio frequency place of reader according to the mode flags position situation being stored in TagB
Generation label card number or two generation label card numbers, TagB transmission data can be received by receiving data at this time, be ensured
Being properly received of railway card number data.If no data returns, there are two kinds of situations, the first situation is that TagA does not connect successfully
Receive pattern upgrade command, still in generation label read-only status, receive at this time data can with TagA from intercept state transition to
The generation label data sent after generation label read-only status；The second situation is the radiofrequency field that TagA has already been through reader
Area, ensure that the train card number data of TagA are correctly identified by reader.
