It is needless to say that technical contents or technical features which are contrary to the object of the present invention or clearly contradicted by the object of the present invention should be excluded.
As shown in fig. 1, an embodiment of the present invention discloses an automatic upgrading method for an electronic tag, which is applied to an automatic upgrading system for an electronic tag (hereinafter referred to as an automatic upgrading system), where the automatic upgrading system includes an upper computer terminal (hereinafter referred to as an upper computer) and a plurality of electronic tags; the automatic upgrading method comprises the following steps of S10-S40:
and S10, the upper computer terminal sends the upgrade preparation broadcast.
In the embodiment of the invention, the upper computer sends the update preparation broadcast to inform all lower computers (namely electronic tags) to carry out automatic grouping. It should be noted that, according to the scheme of the present invention, the broadcast does not need to cover all the electronic tags to be upgraded, but only needs to cover as much as possible, so that the upper computer terminal is in communication connection with part or all of the electronic tags. The electronic tag which does not receive the broadcast of the upper computer can receive the broadcast data of the electronic tag in the subsequent grouping process to know that the upgrade is prepared and the grouping before the upgrade is finished.
S20, when the electronic tag receives the upgrade preparation broadcast, starting an automatic team forming mode to enable the electronic tag and other electronic tags related to the electronic tag to form a tag group; wherein the label group comprises a group leader label and a plurality of group member labels; when the group member label is used as the child device, the parent device corresponding to the child device is one electronic label in the label group, and the group leader label is the parent device at the highest level in the label group.
In the embodiment of the present invention, the upgrade preparation broadcast received by the electronic tag may be sent by the upper computer, or may be sent by other electronic tags in communication connection with the upper computer. When the upper computer is only in communication connection with part of the electronic tags, the part of the electronic tags can be used as a repeater, and the upper computer is in indirect communication connection with other electronic tags which are not in communication connection with the upper computer. The electronic tags to be upgraded can be automatically divided into a plurality of tag groups.
And S30, the upper computer terminal sends the upgrade data broadcast.
And after the automatic grouping of the electronic tags to be upgraded is finished, the upper computer sends an upgrading data packet. The upgrade data may be segmented, each segment comprising at least: total number of segments, length of data of segments, and check value of data of segments.
And S40, after receiving the upgrade data broadcast, the electronic tag performs data transmission complementation with the corresponding parent device or child device in the tag group according to part or all of the upgrade data received by the electronic tag, so as to complete the packet upgrade.
After the upper computer sends all the upgrading data and finishes the upgrading data broadcasting, each electronic tag can only completely receive one part of the upgrading data possibly, grouping upgrading is carried out at the moment, data intercommunication is carried out in each tag group on the premise that the tag groups are not interfered mutually, and data sharing in the groups is guaranteed, so that whether data intercommunication exists or not is carried out in each tag group, the success rate of batch upgrading is improved, parallel upgrading is realized, the upgrading time can be effectively shortened, and the efficiency of batch upgrading is improved.
When the group upgrading is started, all the electronic tags with data missing can display upgrading failure marks, namely, an alarm signal for representing upgrading failure is sent out, for example, an led light or a buzzer indicates that the upgrading is not completed by oneself until all the data are received.
And after the packet upgrading is completed, if the electronic tag still detects that the electronic tag does not receive all upgrading data, the electronic tag can also send out an alarm signal for representing upgrading failure. For example, an electronic tag with missing data may indicate failure of upgrading itself through led light or a buzzer.
Therefore, an operator can collect the electronic tags which fail to be upgraded according to the upgrade failure alarm prompt and then integrate the electronic tags together to perform supplementary upgrade. Compared with the traditional method of collecting all electronic tags to one place for upgrading, the method only carries out traditional processing on the electronic tags with partial upgrading failure after the automatic upgrading is finished, does not need to arrange an additional upper computer, does not need to collect all the electronic tags, and can save equipment and labor cost.
For example, suppose that 200 electronic tags in a warehouse are upgraded, an upper computer is placed in the center of the warehouse, and a command for preparing the upgrade is sent for broadcasting. After receiving the command, the electronic tags to be upgraded are automatically grouped, and after 2 seconds, the electronic tags are divided into 3 tag groups according to the similarity in spatial relationship (namely the radiation range of the broadcast signals). And after grouping is finished, the upper computer broadcasts the upgrading data. The upper computer only needs to broadcast once, and each label subgroup has or not to communicate in the subgroup to the received upgrade data, and the upgrade data is transmitted layer by layer. After 5 minutes or 5 repeated cycles of layer-by-layer delivery, all automatic packet upgrades are finished. And finally, collecting sporadic electronic tags still flashing the LED light in a warehouse by operating personnel, and uniformly upgrading the electronic tags.
As an alternative implementation, as shown in fig. 2, in step S20, the electronic tag initiating an automatic team formation mode to make the electronic tag form a tag team with other electronic tags associated with the electronic tag may include the following steps S21 to S25:
and S21, the electronic tag adjusts the self transmitting power to the lowest gear so as to start the automatic formation mode.
And S22, in the automatic team forming mode, the electronic tag determines the corresponding broadcast time slot according to the own equipment number.
Each electronic tag determines a broadcast time slot according to the own equipment number, so that the simultaneous broadcast and mutual interference of all tags are avoided. The device number and the broadcast slot may be positively or negatively correlated. If a positive correlation is used, one possible method is to select the number according to the first digit of the number, for example, tag No. 1 starts broadcasting 10ms after the start of grouping (i.e., the automatic grouping mode is started), tag No. 2 starts broadcasting 20ms after the start of grouping, tag No. 3, tag No. 13 both start broadcasting 30ms after the start of grouping, and so on.
The broadcast information is divided into two types, one is to-be-grouped information, the content at least comprises the device number of the content and information representing that the parent device is not found, the other is grouped information, and the content at least comprises the device number of the content and the device number of the parent device. Throughout the grouping process, the electronic tags listen for broadcasts from other electronic tags.
S23, the electronic tag determines whether the broadcast information of at least one previous electronic tag is received before the broadcast time slot arrives. Wherein, the prior electronic tag is any electronic tag with a broadcasting time slot prior to the electronic tag. If yes, go to step S24; otherwise, step S25 is executed.
The broadcast information comprises information to be grouped or grouped. That is, the previous electronic tag may or may not have found the parent device.
S24, the electronic tag determines an associated electronic tag from at least one previous electronic tag, the associated electronic tag is used as a father device of the electronic tag, and the grouped information is broadcasted when the broadcasting time slot arrives, so that the electronic tag and other electronic tags associated with the electronic tag form a tag group.
If the electronic tag receives the broadcast information of a previous electronic tag before the broadcast time slot arrives, the parent-child relationship between the electronic tag and the electronic tag needs to be determined, and then the number of the parent device or the number of the child device of the electronic tag needs to be recorded. Only one previous electronic tag may be determined as the associated electronic tag to be the parent device of the electronic tag.
If the electronic tag receives the broadcast information of a plurality of previous electronic tags before the broadcast time slot arrives, it is necessary to determine an associated electronic tag as a parent device of the electronic tag. It should be noted that any one of the plurality of previous electronic tags may be used as a parent device of the electronic tag.
In other possible embodiments, the better prior electronic tag can be selected as the associated electronic tag randomly or by setting different selection conditions. In the present embodiment, it is preferable that the broadcast time slot of each previous electronic tag is determined according to the broadcast information, and then the electronic tag with the first broadcast time slot is determined as the associated electronic tag. In this embodiment, since the device number and the broadcast time slot adopt a positive correlation relationship, the device number of each previous electronic tag may also be obtained according to the broadcast information, and then the electronic tag with the smallest device number is determined as the associated electronic tag.
After the associated electronic tag is determined to be used as the parent device of the electronic tag, the grouped information can be directly broadcast when the broadcast time slot arrives, the content at least comprises the device number of the associated electronic tag and the device number of the parent device, and the representation shows that the parent device and the device number of the parent device are found. And after the grouped information is broadcasted, the broadcasting is not carried out any more, and only the broadcasting from other electronic tags is monitored.
And S25, the electronic tag broadcasts the information to be grouped when the broadcast time slot arrives, so that the electronic tag and other electronic tags related to the electronic tag form a tag group.
If the electronic tag does not receive the broadcast information of at least one prior electronic tag before the broadcast time slot arrives, the electronic tag is the electronic tag with the minimum equipment number or the electronic tag with the longer distance from the prior electronic tag, therefore, the information to be grouped is broadcast first, the content at least comprises the equipment number of the electronic tag and the information representing that the parent equipment is not found, and the broadcast from other electronic tags is monitored.
If the electronic tag does not receive the broadcast information of other electronic tags within a first specified time (such as 100ms) after the information to be grouped is broadcast, and the duration of entering the automatic grouping mode does not reach a second specified time (such as 2000ms), indicating that the electronic tag does not find the parent equipment and does not time out, judging that the current transmission power is too small by the electronic tag, and increasing the transmission power of the electronic tag by one gear to restart the automatic grouping mode for broadcasting again; wherein the second specified duration is greater than the first specified duration. If the electronic tag does not receive the broadcast information of other electronic tags within a first specified time length after the information to be grouped is broadcast, and the duration of entering the automatic grouping mode reaches a second specified time length, that is, the parent device and the child device are not found, and the time is out, the electronic tag determines that the electronic tag is a group leader tag.
In addition, after the electronic tag broadcasts the information to be grouped, if any grouped information broadcasted by a subsequent electronic tag is received, and the grouped information of the subsequent electronic tag represents that the subsequent electronic tag is not a child device of the electronic tag, the electronic tag takes the subsequent electronic tag as a parent device of the electronic tag; the electronic tags broadcast the grouped information so that the electronic tags and other electronic tags related to the electronic tags form a tag group; wherein, the following electronic tag is any electronic tag with a broadcasting time slot later than the electronic tag. That is, if the electronic tag does not find the parent device, but a succeeding electronic tag broadcasted behind it has a found parent device, and the parent device of the succeeding electronic tag is not the electronic tag itself, the succeeding electronic tag can be made the parent device of the electronic tag.
In addition, after the electronic tag broadcasts the information to be grouped, if any grouped information broadcasted by a subsequent electronic tag is received, and the grouped information of the subsequent electronic tag represents that the subsequent electronic tag is a sub-device of the electronic tag, the electronic tag records the subsequent electronic tag into a sub-device list of the electronic tag. That is, the electronic tag does not find the parent device, and the electronic tag selects the later electronic tag broadcasted later as its parent device, and the electronic tag uses the later electronic tag as its child device.
Further, after the electronic tag records the subsequent electronic tag into its own child device list, if the duration of entering the automatic team formation mode reaches the second designated duration, that is, if the electronic tag still does not find a parent device (but may find several child devices), the electronic tag determines that it is the most superior parent device, that is, the team leader tag, and does not find the parent device any more.
An example is listed below to illustrate the above described electronic tag self-grouping process. As shown in fig. 3, for convenience of description, it is assumed that the broadcast of each device (i.e., the electronic tag) can be received only by the device closest to it. In this embodiment, the broadcast slot is positively correlated with the device number. The judgment criteria for specifically determining the parent-child device at least include A, B, C, D:
A. if neither device determines the parent device, numbering the child as the parent device;
B. if one of the two devices determines the parent device and one does not, it has been determined that the device of the parent device is the parent device of the other device;
C. if both devices have determined the parent device, then the parent-child relationship is no longer confirmed;
D. if a plurality of device alternatives exist, the device with the smallest number is selected as the parent device.
For example, the following 7 states are included in the electronic tag self-grouping process:
state 1: at the beginning of the grouping, i.e. upon entering the automatic grouping mode, all devices have no parent device. Starting from device 0, which is the first broadcast slot, device 0 broadcasts its own device number No. 0, and has no parent device.
State 2: both device 2 and device 3 have received the broadcast from device 0. At 10ms, device 1 broadcasts its own number 1, and has no parent. Device 3, device 8, and device 9 all received the broadcast from device 1. At 20ms, device 2 determines that device 0 is its parent device according to criteria a described above. And broadcast, its own number 2, parent device number 0. Device 0, device 3, and device 5 all receive the broadcast from device 2, and device 0 adds the number 2 to its own list of child devices after receiving the broadcast.
And a state 3: at 30ms, that is, when the broadcast slot of the device 3 arrives, the device 3 has already received the broadcasts of the device 0, the device 1, and the device 2 whose broadcast slot is prior in turn, and selects the device 0 with the smallest number (that is, the broadcast slot is prior) as the parent device according to the above criterion D. Thus, at 30ms, device 3 broadcasts its own number 3, the parent device being number 0. Device 0, device 1, device 2, and device 9 all received the broadcast from device 3. Device 0 adds number 3 to its own list of child devices after receiving the broadcast.
And 4, state 4: the device 5 has the device 2 as its parent device according to the above-mentioned standard a. The 50ms broadcasts its own number 5, and its parent device is number 2. Device 2, device 8, device 9 receive its broadcast. Device 2 adds number 5 to its own list of child devices after receiving the broadcast.
And state 5: device 8 takes device 1 as its parent device according to standard a described above. The 80ms broadcasts its own number 8, and its parent device is number 1. Device 1, device 5, device 9 receive its broadcast. Device 1 adds number 8 to its own list of child devices after receiving the broadcast.
And 6, state: the device 9 has the device 1 as its parent device according to the above-mentioned standard a. The 90ms broadcasts its own number 9, and its parent device is number 1. Device 1, device 3, device 5, device 8 receive its broadcast. Device 1 adds number 9 to its own list of child devices after receiving the broadcast.
And state 7: device 0, which did not find a parent, increased the transmit power by one, and continued broadcasting at 100 ms. But both devices 2, 3 that received the broadcast have already broadcast their own queued information and will no longer respond to the broadcast. Device 1 has received the already team information of device 3 broadcast father device, according to above-mentioned standard B, regard device No. 3 as its own father device, at 110ms, device 1 broadcasts its own serial number 1, its own father device is No. 3, device 8, device 9 have received the broadcast of device 1, add device No. 1 into its own child equipment list after device 3 receives the broadcast. So far, all devices in the area have found a parent device except device 0. When the defined 2000ms total time expires, device 0 still does not find a parent device, it marks itself as the group length of the packet.
As an alternative embodiment, the specific implementation manner in step S40 is as follows:
the packet upgrading process is divided into a first stage and a second stage, wherein the first stage is a process of requesting data from a parent device layer to a child device, and the second stage is a process of requesting data from the parent device layer to the child device layer.
In the first stage, starting from the parent device at the uppermost level in each tag group, each parent device checks each received segment data, and marks an unreceived data segment or a data segment failed in checking as a missing data segment. Then, broadcast first data request information is sent to its sub-devices, data segments missing by itself are reported to request data, and its sub-devices are designated to reply. And after broadcasting, entering a data receiving state and waiting for the child equipment to reply.
Further, in order to avoid the mutual interference caused by the simultaneous replies of the child devices, the parent device may specify the reply timing of the child device in the broadcast content, for example, the parent device has two child devices, and may allow the first child device to reply 1ms after receiving the broadcast and allow the second child device to reply 21ms after receiving the broadcast.
Therefore, after receiving the broadcast of the parent device, the child device needs to determine whether the first data request information carries opportunity information, and if the first data request information carries the opportunity information, the child device determines a reply opportunity corresponding to the child device. And checking the received complete data segment to see whether the requirement of the father equipment is met, if so, broadcasting first reply information at a reply opportunity, wherein the reply content comprises the segment number, the segment length, the data content and the data check value of the data.
After the first reply information is broadcasted by the child device, whether the child device exists or not is judged, if the child device exists, the child device is used as a parent device, and missing data is requested from the child device; if there is no sub-device, it indicates that the sub-device is the lowest level sub-device. That is, the first phase in which the parent device layer requests data from the child device ends, and the second phase in which the child device layer requests data from the parent device begins.
In the second stage, the second data request information is broadcasted from the child device of the lowest level without the child device to the parent device to request the missing data segment. And after receiving the broadcast request of the child device, the parent device replies to the child device, namely, broadcasts second reply information aiming at the second data request information. Then the father device judges whether the father device exists or not, if the father device exists, the father device is used as a child device, and second data request information is broadcasted to the father device of the father device; if no father device exists, the father device is the most superior father device, the built-in counter is controlled to count the cycle times and increase by one, whether the cycle times reach the specified times (such as 5 times) is judged, if not, the processes of the first stage and the second stage are repeatedly executed until the cycle times reach the specified times, and the packet upgrading is judged to be completed.
Therefore, in step S40, for each electronic tag, it is necessary to determine whether there is a corresponding parent device and a corresponding child device; to determine which level the tag itself belongs to. Wherein, the first and the second end of the pipe are connected with each other,
if the parent device exists, the electronic tag needs to broadcast first reply information aiming at the received first data request information broadcast by the parent device; then further judging whether the sub-equipment exists or not;
if the parent equipment exists and no child equipment exists, the electronic tag determines that the electronic tag is the child equipment at the lowest level in the tag group, judges that the first stage is finished after broadcasting the first reply information, starts the second stage and broadcasts second data request information to the parent equipment;
if the parent device and the child device exist, the electronic tag broadcasts first reply information to the parent device in the first stage, and then broadcasts first data request information to the child device; and when receiving the second data request information broadcasted by the child device in the second stage, broadcasting second reply information aiming at the second data request information, and then broadcasting the second data request information to the parent device.
