When the gateway equipment only supports a single channel for communication, an upgrade data packet is broadcast to a target terminal through a second channel in a half-duplex mode, and reported information of a plurality of target terminals communicated with the gateway equipment is monitored through a first channel, wherein the first channel and the second channel are both the single channel;
specifically, when the gateway device only supports a single channel for communication, the gateway device can only receive data reported by the terminal through the channel or broadcast a data packet carrying upgrade data to the terminal, in the prior art, the single-channel gateway device cannot receive data reported by the current terminal or other terminals when broadcasting the upgrade data to the terminal, but because a fire alarm requires that a message of a terminal node can be reported to a server within 10 seconds, the existing wireless-based fire alarm system cannot well meet the requirement of timely reporting of the fire alarm;
based on this, the embodiment of the present application provides that when the gateway device broadcasts the data packet carrying the upgrade data to the target terminal through the second channel, the gateway device monitors the report information of the multiple target terminals in communication with the gateway device through the first channel in turn, or simultaneously monitors the report information of the multiple target terminals in communication with the gateway device through the first channel, specifically, but not limited to, presetting a timing conversion time, when the time for the gateway device to broadcast the data packet to the target terminal exceeds the timing conversion time, the gateway device converts the current channel into the first channel to monitor the report information of the multiple target terminals in communication with the gateway device, and after a period of receiving time continues, broadcasts the upgrade data packet using the channel as the second channel, and the above processes are repeated until the gateway device broadcasts the upgrade data to the target terminal, and closes the second channel, the specific flow chart is shown in fig. 2.
2) Full duplex mode
When the gateway equipment supports multi-channel communication, a data packet carrying upgrading data is broadcasted to a target terminal through a second channel in a full-duplex mode, and reported information of a plurality of target terminals communicating with the gateway equipment is monitored through a first channel;
specifically, when the gateway device supports multi-channel communication, the gateway device may select one of the channels as a first channel, and select another channel except the first channel as a second channel, so that when the upgrade data packet is broadcast to the target terminal through the second channel, the gateway device monitors the report information of the plurality of target terminals communicating with the gateway device through the first channel, where a specific flowchart is shown in fig. 3.
Optionally, for a data packet carrying upgrade data, a format of the communication data includes at least one of:
1) an upgrade identifier for indicating the target terminal to start upgrading, where optionally, the upgrade identifier may be represented by a specific numerical value, specifically, the upgrade identifier may be set to 1 to indicate that the terminal starts upgrading, and the size of the upgrade identifier in this embodiment of the present application is 1 byte;
2) the upgrade data subpackage serial number is used for indicating the upgrade data state, optionally, the terminal can check the current upgrade data state at any time according to the upgrade data subpackage serial number, in the embodiment of the application, the size of the upgrade data subpackage serial number is 2 bytes;
3) the upgrade data content is used for indicating the upgrade of the target terminal, optionally, the terminal performs specific upgrade operation according to the upgrade data content, in this embodiment, the size of the upgrade data content is 48 bytes;
4) a CRC16 check value, optionally, a CRC16 check value, used to indicate the target terminal to determine whether the data packet is correct, where the CRC16 check value is used to enable the terminal to quickly determine whether the current upgrade data packet is correct, if the current upgrade data packet is correct, the upgrade packet is stored in a specified address location, an upgrade flag is set to 1, and if the upgrade packet is determined to be incorrect, the upgrade packet is discarded, and the upgrade flag is set to 0.
Optionally, when it is determined that the upgrade data is completely broadcast, broadcasting an upgrade end command to the target terminal through a second channel, so that the first target terminal converts the current channel from the second channel to the first channel; as an optional implementation manner, when the upgrade is abnormal, an upgrade end command may also be broadcast to the target terminal through the second channel, so that the first target terminal switches the current channel from the second channel to the first channel, where the upgrade abnormal condition includes but is limited to an abnormal behavior of the gateway device, or an abnormal behavior of the terminal such as power failure.
Optionally, the communication data in the upgrade end command includes an upgrade identifier for instructing the target terminal to end the upgrade, and specifically, the upgrade identifier may be identified by a specific numerical value, for example, setting the upgrade identifier to 0 to indicate the upgrade end command.
And by adopting a broadcast upgrading mode, the upgrading efficiency can be greatly improved. Taking a gateway device connected with 32 terminals as an example, compared with the original traditional point-to-point scheme, under the condition that upgrade failure is not considered, a point-to-point upgrade scheme is adopted, the upgrade time of the gateway device for completing one terminal is assumed to be 5min, the upgrade of all terminals is completed, and the total time required is 5min x 32-160 min. And the embodiment of the application adopts the broadcast mode for upgrading, and because all the terminals receive the upgrading packet data at the same time, the time for completing upgrading is only 5min, and the upgrading efficiency is greatly improved.
Optionally, after the broadcast upgrade is completed, the gateway device sends a message for confirming the upgrade state to at least one target terminal in turn, and receives an upgrade data table reported by at least one target terminal with upgrade failure, wherein the upgrade data table carries an identifier indicating whether each upgrade data sub-package is successfully received by the target terminal;
the gateway equipment determines at least one target terminal which fails in upgrading according to the upgrading data table;
and the gateway equipment transmits an upgrade data sub-packet carrying the unreceived upgrade data to the at least one target terminal failed in the upgrade through a second channel by adopting a half-duplex or full-duplex mode, and receives the data reported by the at least one target terminal failed in the upgrade through a first channel.
Specifically, the upgrade table introduced by the terminal has 175 bytes in total, each byte has 8 bits, each bit represents the state of 1 upgrade package, and can represent the upgrade state of 1400 upgrade packages at most, if the terminal receives the upgrade data package successfully, 1 is set at the corresponding position, otherwise, 0 is set. (an upgrade file of 67K size can be supported, calculated as 48 bytes per upgrade package).
In the prior art, after the upgrade fails, when a failed terminal communicates with the gateway device again, the terminal communication node communicates with the gateway device at random to acquire information of a failed upgrade package, and by adopting the method, the failure of acquiring the upgrade package may occur under the condition that a plurality of terminal communication nodes communicate simultaneously, which is low in efficiency, but the method of the embodiment of the application is summarized.
