Embodiment one
Referring to Fig. 1, propose the firmware upgrade method of the Zigbee equipment of first embodiment of the invention, methods described include with
Lower step：
S11, gateway are grouped to the Zigbee equipment of access, and every group of Zigbee equipment has the firmware of same type.
When S12, gateway receive update notice, it is determined that the target group upgraded is needed, and to all in target group
The firmware of Zigbee equipment carries out batch upgrade.
In step S11, the Zigbee equipment with identical firmware is divided into one group by gateway (or Zigbee gateways), specifically
During implementation, the facility information of the Zigbee equipment of access can be read, Zigbee equipment is grouped according to facility information, institute
Stating facility information includes device type, scheme type, firmware type, firmware version etc..Wherein, scheme type refers to Zigbee
Chip solution, the description during upgrading that need to be used, such as TI schemes, NXP schemes, EMBER schemes etc., the firmware of different schemes
Can not be compatible, i.e., the different firmware of different scheme correspondences.
Alternatively, gateway reads the exclusive identification code of the firmware of Zigbee equipment, according to only when Zigbee equipment is added
One identification code identifies the firmware type of Zigbee equipment, and after Zigbee equipment adds gateway, gateway is just identical firmware class
The Zigbee equipment of type assigns to same group.
Alternatively, gateway reads the exclusive identification code and version of the firmware of Zigbee equipment when Zigbee equipment is added
Number, the firmware type and firmware version of Zigbee equipment are identified respectively according to exclusive identification code and version number, when Zigbee is set
Standby to add after gateway, the Zigbee equipment of identical firmware type and firmware version is just assigned to same group by gateway.
Alternatively, gateway reads the device type (such as model) and scheme of Zigbee equipment when Zigbee equipment is added
Type, after Zigbee equipment adds gateway, gateway is just assigned to the Zigbee equipment of identical device type and scheme type together
One group, the Zigbee equipment with identical device type and scheme type has identical firmware type.
Alternatively, gateway reads device type, scheme type and the firmware of Zigbee equipment when Zigbee equipment is added
Version, after Zigbee equipment adds gateway, gateway just sets the Zigbee of identical device type, scheme type and firmware version
Back-up is to same group.
As shown in Fig. 2 be the example of firmware upgrade system one of Zigbee equipment, the system include a server, one
Gateway and multiple Zigbee equipment.Zigbee equipment includes 9 lamps and 8 curtain controllers (abbreviation curtain in Fig. 2), and gateway will
9 lamps (lamp 1- lamps 9) with identical firmware type assign to a group A, by 8 curtain controllers with identical firmware type
(curtain 1- curtain 8) assigns to a group B.
It will be understood by those skilled in the art that in addition to the above-mentioned mode enumerated, other manner pair can also be used
Zigbee equipment is grouped, as long as ensureing that every group of Zigbee equipment has a firmware of same type, the present invention to this not
Enumerate and repeat again.
In step S12, when gateway receives the update notice of the Zigbee equipment of server transmission, first according to solid
Facility information and/or firmware information in part upgrade notification determine the target group of corresponding Zigbee equipment, obtain new firmware
Version number, judges whether the version of new firmware is newer than the version of the existing firmware of the Zigbee equipment in target group, if it is,
Server is notified to upgrade, the upgrading data that the reception server is sent, and all Zigbee equipment transmission into target group
Upgrading data, to carry out batch upgrade to the firmware of all Zigbee equipment.
Alternatively, as shown in figure 3, the idiographic flow that gateway sends upgrading data comprises the following steps：
S121, gateway judge whether the quantity of the Zigbee equipment in target group is more than threshold value.When the number of Zigbee equipment
When amount is not more than threshold value, into step S122；When the quantity of Zigbee equipment is more than threshold value, into step S123.
The threshold value can be set as 1, i.e.,：When only one of which Zigbee equipment, transmitted using mode of unicast；When more than
During one Zigbee equipment, then using multicast transmission.
Practice find, when there is two Zigbee equipment, unicast transmission actually than multicast transmission speed faster, therefore,
In an alternative embodiment, 2 are set the threshold to, i.e.,：When only one of which or two Zigbee equipment, passed using mode of unicast
It is defeated；When more than two Zigbee equipment, then using multicast transmission.
Certainly, the threshold value can also be set as other values according to actual needs, and this is not limited by the present invention.
The Zigbee equipment transmission upgrading data of S122, gateway using mode of unicast into target group.
In this step S22, when the quantity of Zigbee equipment in target group is not more than threshold value, gateway then uses mode of unicast
Transmission upgrading data.Unicast transmission is man-to-man transmission means, is transmission means commonly used in the prior art, does not go to live in the household of one's in-laws on getting married herein
State.
All Zigbee equipment transmission upgrading data of S123, gateway using multicast mode into target group.
In this step S123, when the quantity of Zigbee equipment in target group is more than threshold value, gateway is then into target group
All Zigbee equipment send an instruction for starting to start multicast upgrading, and using multicast transmission upgrading data.It is preferred that
Ground, gateway is in transmission upgrading data, and the data that will upgrade are divided into N (N is the integer more than the 0) sequence number of individual carrying from small to large
The packet of (1-N), and sent by multicast mode；When Zigbee equipment receives each packet, verify first with
Ensure that the packet received is correct, after verification passes through, upgrading data are written to corresponding firmware upgrade Flash regions
(can be without doing any reply to gateway), records the sequence number of currently processed packet after operating successfully.
Multicast transmission is one-to-many transmission means, is referred to information while one group of destination address is passed to, in sender
Realize that point-to-point configuration is connected between each recipient.It is most efficient using strategy, because message is in every network
It need to only be transmitted once on link, and only in link bifurcated, message can be just replicated, so as to improve data transmission effect
Rate, reduces backbone network and the possibility of congestion occurs.
Alternatively, related Zigbee equipment is received after multicast upgrading instruction, and the quick tupe that can open multicast is passed
Defeated upgrading data, quick tupe is that Zigbee equipment all in target group continuously can receive forwarding group in the short time
Broadcast the broadcast mode of bag (i.e. the packet of multicast transmission).Under quick tupe, the multicast packets cached when Zigbee equipment
Quantity when reaching threshold value, then abandon the multicast packets cached earliest, be that next new multicast packets vacate spatial cache, so that one
Aspect prevents new multicast packets reception failure from causing to receive data imperfect, on the other hand can improve transmission speed.
Further, after upgrading data end of transmission, gateway judges whether not receive complete upgrading data
Zigbee equipment；When exist do not receive complete upgrading data Zigbee equipment when, gateway again use mode of unicast to
The Zigbee equipment transmits the upgrading data of its missing.So as to ensure that all Zigbee equipment in target group can successfully rise
Level, improves the reliability of system.
When it is implemented, all into target group after gateway is sent completely upgrading data, then by multicast
Zigbee equipment sends the order of a upgrading data end of transmission, and this order carries maximum sequence number N and according to target
The largest random delay T of the quantity generation of Zigbee equipment in group.Zigbee equipment is received after order, judges whether to have received
1-N packet, the notice of a packet completely is replied if having received by mode of unicast to gateway, it is preferable that
A random delay T (T can be when notifying by replying>0), to prevent from having substantial amounts of Zigbee device replieds in same time target
The notice and cause network congestion so that data send failure.Gateway is received after the notice of packet completely, by unicast side
Formula sends a confirmation to corresponding Zigbee equipment, and Zigbee equipment receives formal progress firmware liter after confirmation
Level.
When gateway does not receive the notice of the packet of a certain Zigbee device replieds in target group completely, this is decided that
Zigbee equipment does not receive complete upgrading data, and gateway does not then seriatim receive ascending series by mode of unicast to these
According to Zigbee environment inquiries lose data packet sequence row number.Zigbee equipment compares the sequence recorded during processing data bag
Number, the sequence number of missing is then returned to gateway.Gateway is received after the sequence number of missing, just the corresponding data of the sequence number
Bag is sent to corresponding Zigbee equipment by mode of unicast, until the corresponding packet of the sequence number of all missings has been sent
Finish.Finally, until gateway confirms that all Zigbee equipment all receive complete upgrading data in target group, and successfully upgrade.
What is used because Zigbee multicast mode is actual is exactly to broadcast, so generally Zigbee equipment seldom goes out
The situation of packet loss is now received, even if it is also a few devices to occur, therefore, in other embodiments, the step can also be omitted.
Further, gateway can simultaneously be consolidated using difference upgrade method to all Zigbee equipment in target group
Part is upgraded.For whole bag upgrading, the upgrading data of difference upgrading only include difference portion of the new firmware relative to old firmware
Point data, therefore compared to new firmware whole data for, the data volume of transmission is smaller, can improve upgrading efficiency.
When it is implemented, while gateway notifies that server can upgrade, also being sent to server in target group
The device type and firmware version or firmware type and firmware version of Zigbee equipment.Server is according to device type and firmware
Version or firmware type and firmware version find corresponding firmware, then according to Memory Mapping File (.map) with function code
Section (code) and data segment (data) compare the similarities and differences of the data of new and old two versions of the firmware for unit, and correspondence is generated afterwards
Difference in version file (hereinafter referred to as difference describes file) is described, difference describes file and is properly termed as difference bag again.
Difference describes file Part I and describes the old firmware in Zigbee equipment and all identical datas in new firmware
Address field (each address field include initial address and end address) and the partial data it is corresponding in equipment firmware download area
Target initial address；Part II describe variance data (non-existent data in i.e. old firmware) and data check value with
And the partial data is in the target initial address of equipment firmware download area and end address.
Server notification gateway is upgraded using difference, i.e., describing file mode using difference upgrades, while difference is described
File is sent to gateway.Alternatively, server generation difference is described after file, first determines whether that difference describes file and original new edition
The size of firmware, normal condition difference, which describes file, can all be much smaller than original new edition firmware, and at this time just notification gateway use is poor
Difference is described file simultaneously and is sent to gateway by different description file mode upgrading, and when difference describes file more than original new firmware
When, then the whole data of original new firmware are sent to gateway by notification gateway using whole bag upgrading.
Gateway describes difference the data that file is divided into the sequence number (1-N) of N number of carrying from small to large as upgrading data
Bag is sent, and file is described for difference, and Zigbee equipment may carry out substantial amounts of data copy in processing data bag
Work, preferably, size of the gateway according to Zigbee equipment end processing data amounts, does in the middle of each two packet of transmission
One delay t (t>0), i.e., a packet is sent every the t times, to ensure that Zigbee equipment ends have time enough processing.
The preferably linear positive correlation of t and the processing data amount size that is delayed.
Zigbee equipment is received after each packet, the packet is verified to ensure the packet received first
Correctly, after verification passes through, then judge whether this packet is packet (difference upgrading) that difference describes file.If
It is that then corresponding data are copied to firmware upgrade by new and old firmware identical data division according to address descriptor according to address
The data received are then directly write corresponding firmware upgrade Flash regions by Flash regions, different data divisions；If
It is that original new firmware data (whole bag upgrading) then directly writes to correspondence firmware upgrade Flash regions.Recorded after operating successfully
The sequence number of currently processed packet.It is after Zigbee equipment receives all upgrading data, then formal to carry out firmware liter
Level.
In the embodiment of the present invention, gateway carries out the idiographic flow of batch upgrade with multicast mode to the firmware of Zigbee equipment
As shown in figure 4, comprising the following steps：
S21, gateway are grouped to the Zigbee equipment of addition.So that every group of Zigbee equipment has consolidating for same type
Part.
S22, gateway receive upgrade notification, it is determined that group A needs upgrading.
S23, gateway receive difference and describe file or new firmware.When carrying out difference upgrading, server sends poor to gateway
Different description file (or difference bag)；When carrying out whole bag upgrading, server directly sends new firmware to gateway.
S24, gateway send starting and upgrading order by multicast mode.The quantity of Zigbee equipment in group A is more than 2, net
Close judgement and meet multicast batch upgrade condition, therefore upgrading is sent by all Zigbee equipment of the multicast mode into group A and open
Dynamic order.
S25, Zigbee equipment enter the quick tupe of multicast (broadcast).Each Zigbee equipment receives starting and upgrading life
After order, the quick tupe of multicast (broadcast) is immediately entered.
S26, gateway send the packet for carrying 1-N sequence numbers by multicast mode successively.Upgrading data are divided into N by gateway
The packet of (N is the integer more than the 0) sequence number (1-N) of individual carrying from small to large, and sent out successively by multicast mode
Go.
S27, Zigbee equipment perform corresponding copy or write-in Flash operations to the packet that verification passes through, and record
Corresponding sequence number.
S28, gateway send the order of packet end of transmission by multicast mode.
The notice (or packet received notice) of packet completely is replied in node unicast that S29, packet are received.Number
The node (the Zigbee equipment that i.e. packet is received) received according to bag is preferably a random delay T (T when sending notice>
0)。
The node unicast that S30, gateway are received to packet confirms that order can upgrade.
The node that S31, packet are received formally enters firmware upgrade state.
Which packet the node that S32, gateway unicast inquiry packet are not received lacks.
When not receiving the notice of the packet of some Zigbee equipment in group A completely, judge that the Zigbee equipment does not have
Have and receive complete upgrading data, then inquire which packet is the Zigbee equipment lack by mode of unicast.
The node unicast that S32, packet are not received returns to the sequence number of the packet of missing.
S33, gateway send the corresponding packet of this sequence number by mode of unicast.
S34, gateway send the order of packet end of transmission by multicast mode.
When Zigbee equipment all packets of the missing of completion of all missing data bags, gateway is sent out by multicast mode
Send the order of packet end of transmission.
The notice of packet completely is replied in the node unicast that S35, packet are received.
S36, gateway unicast confirm that order can upgrade.
Repeat step S32-S36, until receiving the notice of the packet of all Zigbee device replieds in group A completely.
