Embodiment 1
[0052] Such as figure 1 and figure 2 Shown, a kind of method that the node in wireless sensor network is carried out wireless upgrading, it comprises the following steps:
[0053] Step 1: Establish a serial port connection between coordinator node 2 and PC 1;
[0054] Step 2: establishing a wireless link connection between the coordinator node 2 and each node 3 to be upgraded in the at least one node 3 to be upgraded;
[0055] Step 3: Send the upgrade program from PC 1 to coordinator node 2 through the serial port;
[0056] Step 4: The coordinator node 2 sends the upgrade program to all nodes 3 to be upgraded through the wireless link;
[0057] Step 5: After confirming that all nodes 3 to be upgraded have successfully received the upgrade program, PC 1 sends a download program start command to coordinator node 2, and coordinator node 2 sends the download program start command to all waiting Upgrade node 3. After node 3 to be upgraded receives the command, write the upgrad...

The invention relates to a method for updating nodes of wireless sensor network in a wireless mode. The method includes the following steps: step 1. establishing serial connection between nodes of a coordinator and a personal computer (PC) end; step 2. establishing wireless link connection between the node of the coordinator and every node to be updated in at least one node to be updated; step 3. sending updating programs from the PC end to the node of the coordinator; step 4. sending the updating programs to all nodes to be updated by the node of the coordinantor; and step 5. after confirming that all nodes to be updated successfully receive the updating program, end sending a download program starting command to the node of the coordinator by the PC, sending the download program starting command to all the nodes to be updated by the node of the coordinator, and after the nodes to be updated receive the command, writing updating programs into a Flash of the nodes to the updated. The method for updating nodes of wireless sensor network in wireless mode has the advantages that as long as equipment to be updated is allocated with a wireless communication module and a writing program, the equipment to be updated can be updated conveniently through the method within tolerable time.
Description
technical field [0001] The invention relates to a method for upgrading programs in a wireless manner, in particular to a method for wirelessly upgrading nodes in a wireless sensor network. Background technique [0002] When developing applications for chips such as single-chip microcomputers (including embedded), generally use a universal programmer or a dedicated programmer to program and debug a single development device. This method is simpler, but also has shortcomings. First of all, a programmer must be used. It is necessary for developers to configure the programmer. Without a programmer, debugging cannot be performed. Once the development process is over and the product is put into practical use, it is expensive to configure a programmer just for programming, so it is no longer possible to change and upgrade the program in the chip through the programmer. Engineering personnel cannot perform program upgrades on site, and dismantling equipment may bring unpredictable...
