In the embodiment of the disclosure, after unpacking an over-the-air OTA data packet to be upgraded, the gateway equipment can broadcast the over-the-air OTA data packet to a multi-node equipment network, so that each node equipment can be upgraded according to the OTA unpacking information obtained by monitoring, and thus, the node equipment of the same type can be upgraded at the same time, the OTA upgrading speed of the multi-node equipment is improved, and the probability of network congestion is reduced. And when the data packet is broadcast, the verification can be performed in a mode of monitoring broadcast response one by one, or in a mode of sending sequence verification information, so that the reliability of OTA upgrading is further improved.
Fig. 2 is a flow chart of an over-the-air method for a multi-node device network according to an embodiment of the present disclosure. As shown in fig. 2, the process of over-the-air downloading in a multi-node device network may include:
step 201: unpacking the acquired over-the-air OTA data packet to be upgraded to obtain unpacking information of each OTA, wherein the unpacking information of the OTA comprises the following steps: the method comprises unpacking OTA data, corresponding sequence identification information and unpacking offset address information.
The gateway device can obtain the upgrade package corresponding to each node device from the cloud device and download the upgrade package to the local. For node devices in the same type, for example: the intelligent lamp in the room, or the intelligent switch, or the security probe, etc., can determine an upgrade package corresponding to a node device of the same type as an over-the-air OTA data package to be upgraded each time, and then unpack the acquired over-the-air OTA data package to be upgraded to obtain unpacking information of each OTA, wherein the unpacking information of the OTA comprises: the method comprises unpacking OTA data, corresponding sequence identification information and unpacking offset address information.
Step 202: broadcasting each OTA unpacking information to a multi-node equipment network, so that each node equipment upgrades according to the OTA unpacking information obtained by monitoring.
In some embodiments, each OTA unpacking information may be broadcast to the multi-node device network in turn, and each time an OTA unpacking information is broadcast, a broadcast response of each node device in the updated whitelist in the network needs to be monitored, and according to the broadcast response, the next OTA unpacking information is broadcast continuously. The gateway device broadcasts the OTA unpacking information with the serial number identification information of n, can wait for the broadcast response of each node device in the upgrade white list in the network, can continue broadcasting the OTA unpacking information with the serial number identification information of n+1 after receiving the broadcast response of each node device in the upgrade white list, and if the broadcast response of one node device in the upgrade white list is not received, needs to send the first OTA unpacking information with the serial number identification information of n to the node device, and continues monitoring. Of course, if the broadcast response of the node device is still not received after the first OTA unpacking information with the sequence number identification information of "n" is sent multiple times, the node device needs to be removed from the upgrade white list, and the OTA unpacking information with the sequence number identification information of "n+1" is continuously broadcast.
Thus, broadcasting each OTA unpacking information into the multi-node device network includes: broadcasting the first OTA unpacking information to a multi-node equipment network; broadcasting second OTA unpacking information to a multi-node device network under the condition that broadcasting response of each node device in the upgrade white list is monitored; and determining that the second OTA unpacking information is arranged behind the first OTA unpacking information according to the sequence identification information. When the OTA unpacking information is broadcast for the first time, the node equipment information in the upgrade white list is matched with the node equipment information corresponding to the OTA data packet to be upgraded.
In some embodiments, under the condition that a broadcast response of a current node device in an upgrade white list is not monitored, adding 1 to a first broadcast frequency corresponding to first OTA unpacking information to obtain an updated first broadcast frequency; and under the condition that the updated first broadcasting times are smaller than the set times, sending the first OTA unpacking information to the current node equipment.
And if the updated first broadcast times are greater than the set times, it may indicate that the current node device is identified by OTA upgrade, and in some embodiments, the current node device is removed from the upgrade white list, and the second OTA unpacking information is broadcast to the multi-node device network. Thus, the OTA unpacking information required by other node equipment is continuously broadcast, and the other node equipment is continuously updated by OTA.
After each node device monitors the obtained OTA unpacking information, the network of the multi-node device can carry out corresponding OTA upgrading.
As shown in fig. 1, the multi-node device network further includes: the cloud device, here, is an IOT platform, further includes a user terminal, so in some embodiments, the gateway device broadcasts each OTA unpacking information to the multi-node device network, and simultaneously sends synchronization progress information to the user terminal application APP through the cloud device, where the synchronization progress information is determined according to the number of OTA unpacking information broadcast to the multi-node device network.
In some embodiments, each OTA unpacking information may be broadcast to the multi-node device network in a sequential or non-sequential manner, and after the OTA unpacking information is determined to be broadcast, sequence verification information may be broadcast, so that the node device performs whole package verification on the received OTA unpacking information according to the sequence verification information, and performs corresponding OTA upgrade after verification is successful.
Thus, broadcasting each OTA unpacking information into the multi-node device network includes: according to the sequence identification information, broadcasting each OTA unpacking information to a multi-node equipment network in sequence; and broadcasting an upgrade ending instruction carrying sequence checking information to the multi-node equipment network under the condition that the broadcasting of the OTA unpacking information is confirmed, wherein the sequence checking information is generated according to each sequence identification information.
After the node equipment monitors the obtained OTA unpacking information, and monitors and obtains an upgrading ending instruction, OTA upgrading can be carried out. In some embodiments, since the upgrade end instruction carries the sequence verification information, verification can be performed according to the sequence verification information and the sequence identification information corresponding to each OTA unpacking information, and after verification is successful, the unpacked OTA data in each OTA unpacking information can be combined and upgraded. And if the verification fails, each OTA unpacking message may be discarded.
Step 203: and receiving the upgrade feedback information reported by each node device.
The node equipment combines the unpacked OTA data in each OTA unpacking information according to the sequence identification information corresponding to each OTA unpacking information, then carries out OTA upgrading, generates upgrading success information after the upgrading is completed, and sends the upgrading success information to the gateway equipment, wherein version information can be carried in the upgrading success information. If the verification fails or the upgrade is not completed, upgrade failure information can be generated and sent to the gateway device, so that the gateway device can receive upgrade feedback information reported by each node device.
In some embodiments, the gateway receiving upgrade feedback information reported by each node device includes: the gateway equipment receives upgrading success information reported by the current node equipment, wherein the upgrading success information is generated by the current node after merging and upgrading the unpacked OTA data in each OTA unpacking information according to the sequence verification information and the sequence identification information in each obtained OTA unpacking information; the gateway equipment receives upgrade failure information reported by the current node equipment, wherein the upgrade failure information is generated by the current node according to sequence verification information and sequence identification information in each acquired OTA unpacking information in a monitoring mode, and after verification failure is determined, each OTA unpacking information is discarded.
Of course, in some embodiments, the gateway device may report version information carried in the upgrade feedback information reported by each node device to the user terminal application APP through the cloud device. Thus, the user can clearly know the OTA upgrading condition of the node equipment.
Therefore, in the embodiment of the disclosure, in the multi-node device network, the gateway device can unpack the over-the-air OTA data packet to be upgraded and broadcast the unpacked OTA data packet to the multi-node device network, so that each node device can upgrade according to the OTA unpacked information obtained by monitoring, and thus, the node devices of the same type can be upgraded at the same time, the OTA upgrading speed of the multi-node device is improved, the probability of network congestion is also reduced, and the broadcast OTA unpacked information can be checked in various modes, so that the reliability of OTA upgrading is further improved.
