Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated.
As shown in Figure 1, the wireless electronic tag when train driving of the present invention and on it carries out in the embodiment of the method for data interaction, and the method comprises the steps:
Step S11 label enters the first transmission state and sends N number of Frame comprising the first specific data continuously: in this step, above-mentionedly be arranged on wireless electronic tag on rail vehicle due to rail vehicle and enter into the radio-frequency field scope of read write line, sense the electromagnetic wave that above-mentioned read write line sends, and then be waken up by dormant state, electrification reset is started working.When above-mentioned wireless electronic tag powers on and starts working, this wireless electronic tag always enters the first transmission state, and under the first transmission state, wireless electronic tag can only send the first specific data of setting in advance.First specific data is normally stored in the train card number data in this wireless electronic tag.In the present embodiment, above-mentioned first specific data, except the train card number data comprising this wireless electronic tag above-mentioned, can also comprise other appointed information, such as car inspection and repair information etc.Certainly, write in advance during above-mentioned first specific data and be stored in above-mentioned wireless electronic tag.In this step, this wireless electronic tag sends above-mentioned first specific data in the form of frames, and specifically, above-mentioned first specific data is put in a Frame by this wireless electronic tag, then these data is sent.In the present embodiment, only first specific data is placed in an above-mentioned Frame.This frame comprising the first specific data that this wireless electronic tag sends has some, and frame very little may cause read write line reception bad; And too many frame likely causes temporal delay.So in this step, this wireless electronic tag sends N number of Frame including the first specific data continuously.The N fixed value that yes sets in advance, its value can be chosen after considering according to actual conditions, such as, can choose between 3-10.Wireless electronic tag enters next step after completing transmission N frame first specific data.
Step S12 label enters first and intercepts state, maintains the first setting-up time T1: wireless electronic tag is because send N frame first specific data in this step, so send State Transferring by first to intercept state to first.That is, this wireless electronic tag is being intercepted under state, stop sending the first above-mentioned specific data (in the present embodiment, in fact in above-mentioned first setting-up time T1, this wireless electronic tag can not send any data), and proceed to first and intercept state and start to receive the instruction sending to this wireless electronic tag, these instructions send out by being arranged on ground read write line (or ground receiving equipment) usually.In this step, the first duration of intercepting state has certain requirements, if the duration is too short, possibly cannot receive the instruction that read write line sends; If the time is oversize, then can cause temporal delay.First setting-up time T1 can be a fixed value of setting in advance, and its value can be chosen after considering according to actual conditions, such as, can choose between 500us-2500us.In addition, in the present embodiment, the length of the first setting-up time T1 also can according to its (wireless electronic tag) enter first intercept state before state or to enter the number of times of the state of intercepting identical or not identical; That is, according to enter first intercept state before the difference of state, above-mentioned first setting-up time T1 can select setting, different numerical value in advance.This makes this wireless electronic tag can adjust according to different situations in the time that first intercepts state, demand during more realistic use.
Whether step S13 receives the first conversion instruction or the second conversion instruction: in this step, judges whether receive the first conversion instruction or the second conversion instruction in above-mentioned first setting-up time T1, if do not had, performs step S14; If had, perform step S15; In this step, this wireless electronic tag judges that whether intercept state first receives the first status switching instruction or the second status switching instruction, if do not receive the first status switching instruction or the second status switching instruction, then returns step 102; If receive the first status switching instruction or the second status switching instruction, perform step 105.First status switching instruction is the same with other instructions with the second status command in the present embodiment has unique operational code, but its operand can change, so the instruction received, once resolved, just can judge this instruction whether the first status switching instruction or the second status command.It is worth mentioning that, in Train motion process, being switched by the state of wireless electronic tag thereon adopt a kind of reliable and stable mode to carry out, so the first status switching instruction or the second status switching instruction to be not suitable for director data more, instruction is consuming time long, the instruction that instruction code check is too high, within first status switching instruction or the second status switching instruction should adopt 50 Bit datas, consuming time about between 300us to 2ms, between code check 40kbps to 160kbps and with the instruction of check bit, such status switching instruction can ensure that wireless electronic tag is reliable and stable and carry out state switching fast.
Whether step S14 label enters by the second transmission state the state of intercepting: in this step, judges that wireless electronic tag has the second transmission state to enter recited above first to intercept state, if so, jump to step S16 no; Otherwise, jump to step S11.It is worth mentioning that, perform when this step is and does not receive the first conversion instruction or the second conversion instruction in step s 13.
Whether the instruction that step S15 receives is the first conversion instruction: in this step, judges whether the instruction received in above-mentioned steps is the first conversion instruction, in this way, performs step S16; Otherwise, perform step S17.The method judged, as described in step S13, obtain its operational code by resolving instruction, thus judges whether it is the first conversion instruction.
Step S16 enters the second transmission state, and send the Frame that M comprises the second specific data continuously: in this step, wireless electronic tag sends M the second specific data in the form of frames, in the present embodiment, second specific data is not data that are fixing or setting, but the data (data namely pointed by the first status switching instruction operand) that the first status switching instruction received in step is above specified.Specifically, the data specified by above-mentioned first status switching instruction are put in a Frame by this wireless electronic tag, then these data are sent.In the present embodiment, the data specified by first status switching instruction are only placed in an above-mentioned Frame.In this step, the frame of the data specified by this first status switching instruction that this wireless electronic tag sends has some, and frame very little may cause read write line reception bad; And too many frame likely causes temporal delay.So in this step, this wireless electronic tag sends the Frame that M includes the second specific data continuously.The M fixed value that yes sets in advance, its value can be chosen after considering according to actual conditions, such as, can choose between 3-10.It is worth mentioning that, in this step, above-mentioned first specified quantity N can be identical with the value of the second specified quantity M, also can be different.
Step S17 enters interaction mode, receive and perform the instruction except the first conversion instruction: in this step, owing to learning that the instruction that this wireless electronic tag receives not is the first status switching instruction by resolving the instruction received, but other instructions, such as, by writing data and to be configured above-mentioned wireless identification tag or the instruction etc. of optimum configurations, certainly also comprise the second status switching instruction; In fact, if the instruction received is the first State Transferring instruction, this step would not be jumped to, so the instruction performed in this step is other instructions except the first conversion instruction.So this wireless electronic tag performs the operation of the command request that it receives, such as, the data of being carried write this wireless electronic tag assigned address etc.
Step S18 label enters second and intercepts state, hold time T2, judge whether to receive instruction: when wireless electronic tag is after executing the instruction that above-mentioned interaction mode receives, perform this step, namely enter second and intercept state, and second intercept in state at this and maintain the second setting-up time T2, then judge in this second setting-up time T2, whether this wireless electronic tag receives instruction (referring to any one instruction herein), if received, returns step S15; If do not receive instruction, then jump to step S11.
In the present embodiment, wireless electronic tag because operation except the first status switching instruction required by other instructions in execution of step S17, so be transformed into second by interaction mode to intercept state.That is, this wireless electronic tag, when second intercepts state, has executed the instruction that read write line sends, and proceeds to second and intercept state and start to receive the instruction sending to this wireless electronic tag.Second duration of intercepting state also had certain requirements, if the duration is too short, possibly cannot receive the instruction that read write line sends; If the time is oversize, then can cause temporal delay.Second setting-up time T2 is a fixed value of setting in advance, and its value can be chosen after considering according to actual conditions, such as, can choose between 1000us-5000us.It is worth mentioning that, in this step, the above-mentioned second setting-up time T2 time can be identical with the value of the first setting-up time T1, also can be different.Wireless electronic tag judges that whether intercept state second receives instruction, if do not receive instruction, then returns step S11; If receive instruction, jump to step S15.In the present embodiment, above-mentioned instruction not only includes the first status switching instruction, the second status switching instruction, also includes other right instructions simultaneously, further comprises false command.False command can be various forms of mistake, such as, and check errors, frame format mistake etc.
It is worth mentioning that, in the method for the present embodiment, no matter which kind of state wireless electronic tag is in, as long as exceed setting-up time do not receive external activation signal, this wireless electronic tag will enter dormant state, and this is the same with the dormancy of general wireless electronic tag.
In the present embodiment, the action of above-mentioned wireless electronic tag is not that it realizes separately, and its workflow cooperatively interacts with the read write line (i.e. ground arrangement for reading) or handhold read-write device that are arranged on railway limit and realizes.Fig. 2 shows read write line in the present embodiment and has coordinated the workflow diagram of data interaction with above-mentioned wireless electronic tag.As shown in Figure 2, its step is as follows:
Step S21 read write line is started working: in this step, and this read write line enters duty, opens read write line power amplifier, sends radio-frequency field, starts to receive data.
Step S22 wait-receiving mode data: in this step, this read write line receives the data of the wireless electronic tag transmission entering its reach.Read write line receives the data of wireless electronic tag transmission in the present embodiment can be the first specific data, also can be the data specified by the first status switching instruction.
Step S23 receives data and completes: in this step, this read write line completes the reception of frame data.Above-mentioned frame data in the present embodiment can be above-mentioned first specific datas, also can be the data specified by the first status switching instruction.
Step S24 judges data: in this step, read write line judges to the data received, judge that the data that receive are the first specific data or the data specified by the first status switching instruction, if what receive is the first specific data, then perform step S25; If what receive is data specified by the first status switching instruction, then return step S22.
Whether step S25 has data to return: in this step, and above-mentioned read write line judges whether it still receives data, if so, then returns step S22; If not, then perform step S26.In the present embodiment, if read write line still receives the data that this wireless electronic tag sends, read write line shows that this wireless electronic tag is still in the first transmission state, do not enter first and intercept state, so will return the data of this wireless electronic tag of step S22 continuation reception transmission; If read write line does not receive the data that this wireless electronic tag sends, at this moment this wireless electronic tag has three kinds of situations, the first situation is that this wireless electronic tag enters first and intercepts state, at this moment read write line sends the first status switching instruction, and this wireless electronic tag will enter the second transmission state and send data specified by the first status switching instruction; The second situation is that this wireless electronic tag is still in the first transmission state, and read write line receives makes mistakes, and now read write line sends the first status switching instruction, and this wireless electronic tag will be ignored; The third situation is that label leaves read write line radio frequency place, and now read write line sends the first status switching instruction, and this wireless electronic tag cannot receive the first status switching instruction.
Step S26 sends the first status switching instruction: in this step, and above-mentioned read write line judges that the countless certificate of above-mentioned wireless electronic tag returns, and therefore, this read write line sends the first status switching instruction to above-mentioned wireless electronic tag.After read write line sends the first status switching instruction, step S22 will be returned.In the present embodiment, after read write line sends the first status switching instruction, may be there are three kinds of situations in label: the first situation has carried out State Transferring after this wireless electronic tag receives the first status switching instruction to enter into the second transmission state and start to send the data specified by the first status switching instruction, and now read write line returns step S22 and can receive the data specified by the first status switching instruction that this wireless electronic tag sends; The second situation is that this wireless electronic tag does not correctly receive the first status switching instruction, and this wireless electronic tag is by continuation transmission first specific data, and now read write line returns the first specific data that step S22 can receive the transmission of this wireless electronic tag; The third situation is that wireless electronic tag leaves read write line radio frequency place, and at this moment read write line returns the first specific data that step S22 can receive the transmission of next wireless electronic tag.
Fig. 3 is the workflow diagram of hand-held read-write in the present embodiment, and it coordinates with the workflow of the wireless electronic tag shown in Fig. 1, jointly realizes the data wireless write-in functions of train electronic tag.As shown in Figure 3, its step is as follows:
Step S31 read write line is started working: in this step, and this read write line enters duty, opens read write line power amplifier, sends radio-frequency field, starts to receive data.
Step S32 wait-receiving mode data: in this step, this read write line receives the data of the wireless electronic tag transmission entering its reach.Read write line receives the data of wireless electronic tag transmission is in the present embodiment generally the first specific data.
Step S33 receives data and completes: in this step, this read write line completes the reception of frame data.Above-mentioned frame data in the present embodiment are generally above-mentioned first specific datas.
Whether step S34 has data to return: in this step, and above-mentioned read write line judges whether it still receives data, if so, then returns step S32; If not, then perform step S35.In the present embodiment, if read write line still receives the data that this wireless electronic tag sends, read write line shows that this wireless electronic tag is still in the first transmission state, do not enter first and intercept state, so will return the data of this wireless electronic tag of step S32 continuation reception transmission; If read write line does not receive the data that this wireless electronic tag sends, at this moment this wireless electronic tag has two kinds of situations, the first situation is that this wireless electronic tag enters first and intercepts state, at this moment read write line sends the second status switching instruction, and this wireless electronic tag performs other instructions except the first status switching instruction by entering interaction mode; The second situation is that this wireless electronic tag is still in the first transmission state, and read write line receives makes mistakes, and now read write line sends the second status switching instruction, and this wireless electronic tag will be ignored.
Step S35 sends the second status switching instruction: in this step, and above-mentioned read write line judges that the countless certificate of above-mentioned wireless electronic tag returns, and therefore, this read write line sends the second status switching instruction to above-mentioned wireless electronic tag.After read write line sends the second status switching instruction, step S36 will be performed.
Whether step S36 has data to return: in this step, and above-mentioned read write line judges whether it still receives data, if so, then returns step S32; If not, then perform step S37.In the present embodiment, if read write line still receives the data that this wireless electronic tag sends, read write line shows that this wireless electronic tag is still in the first transmission state, do not enter first and intercept state, so will return the data of this wireless electronic tag of step S32 continuation reception transmission; If read write line does not receive the data that this wireless electronic tag sends, show that this wireless electronic tag enters interaction mode and performs other instructions except the first status switching instruction.
Step S37 sends other instructions of non-first switching command: in this step, above-mentioned read write line can send other instructions of non-first status switching instruction, will enter step 308 and intercept the response condition of wireless electronic tag after read write line sends instruction.In the present embodiment, above-mentioned non-first status switching instruction can be the instructions such as reading and writing, locking, unblock, every bar instruction all has unique operational code, but its operand can change, so, the instruction received is once resolved, and wireless electronic tag just can respond according to instruction operands.
Step S38 intercepts wireless electronic tag response condition: in this step, and above-mentioned read write line intercepts the response condition of wireless electronic tag, returns step S37 and sends next instruction.In the present embodiment, by the circulation of step S37, step S38, the data that can realize writing or changing required for user are to this wireless electronic tag assigned address; Read the operations such as the data in wireless electronic tag storage unit.
Fig. 4 is the position view of rail vehicle and wireless electronic tag in embodiment, read write line.Its work process is as follows: each rail vehicle is arranged a wireless electronic tag, rail vehicle is interconnected, when train passes through the radio frequency place of ground arrangement for reading, the wireless electronic tag be loaded on rail vehicle will sequentially enter the radio frequency place of ground arrangement for reading.In the diagram, when TagA(is contained in the wireless electronic tag on a rail vehicle) when entering the radio frequency place of ground arrangement for reading, ground arrangement for reading starts to receive the first specific data be stored in TagA that TagA sends.After ground arrangement for reading successfully receives the first specific data being stored in TagA that TagA sends, ground arrangement for reading waits for that TagA enters first and intercepts state and stop transmission first specific data, and now ground arrangement for reading sends the first status switching instruction.After the first status switching instruction is sent, if there are data to return, there are three kinds of situations, the first situation is the wireless electronic tag that TagB(is contained on another rail vehicle) also do not enter the radio frequency place of ground arrangement for reading, TagA successfully receives the first status switching instruction, the second transmission state that is still in sends the data specified by the first status switching instruction, and the data that now reception data can receive specified by the first status switching instruction can comprise train card number data and user data etc.; The second situation is the wireless electronic tag that TagB(is contained on another rail vehicle) also do not enter the radio frequency place of ground arrangement for reading, TagA can successfully not receive the first status switching instruction, and the first transmission state that is still in sends the first specific data; The third situation is because train running speed is very fast, TagA have passed the radio frequency place of ground arrangement for reading, TagB starts after entering the radio frequency place of ground arrangement for reading to send its first specific data, now receive data and can receive the first specific data stored in TagB, ensure that the correct reception of train card number data.If countless certificate returns, there are two kinds of situations, the first situation is that TagA does not successfully receive the first status switching instruction, is still in first and intercepts state, now receive data can TagA intercept state transition to the first transmission state from first after the first specific data of sending; The second situation is the radio frequency place that Tag have passed ground arrangement for reading, ensure that the train card number data of TagA are correctly identified by ground arrangement for reading.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
