The above features and advantages of the present invention will become more apparent from the following description of the embodiments of the invention. [Embodiment] The device for updating the firmware according to an embodiment of the invention is shown in Figure 1. The device (10) including the main device (10) includes the wireless network module 12G and the child. The single secret port 13〇, the child early M0, and the storage unit interface 150 are processed. Update #勒1(8) is through the pain of tenderness (netwG/sfg=, all electronic devices are updated (4) (f__M action). The following describes the components in the device 100 for updating the device. c_ 1 The processing unit 110 is, for example, a Micro Unit 'MCU' for controlling the operation of the device (10) for the entire update. The wireless network module 120 is connected to the main processing unit 11 for 9 201025134 -- ---------- 30127twf.doc/n Connect to a wireless network, where the wireless network module 12〇 includes the hardware, software components, or hardware and software components required to connect to the wireless network. The wireless network may be a WiFi wireless network or the like, and the bean range is not limited herein. The eight-child processing unit interface 13 is connected to the main processing unit 13A to facilitate firmware update of the electronic device. In the embodiment, the sub processing unit 140 is, for example, an integrated circuit chip (Inte ted Circuit Chip 'IC Chip), and after being inserted into the sub processing interface 130, the main processing unit 11 can be passed through the main processing unit 11 〇 to pass the wireless network mode 120 pairs of all electronic devices in the network segment are updated. Among them, the electronic device that needs firmware update is, for example, a digital photo frame (10), which does not limit the type of electronic device. As shown in Fig. 1, the storage unit interface 15 is also connected to the main processing unit no, and can be inserted into various storage units (not shown) such as a security digital (SD) card. After the storage unit is inserted into the storage unit interface 150 The sub-processing unit sorts the electronic devices in the network segment by the address of the network protocol (IP address) of the network segment recorded by the main processing unit and the data storage unit. In order to further explain the detailed operational flow of the device 100 for updating the service, another embodiment will be further described below. FIG. 2 is an update of the blade according to an embodiment of the present invention. Flowchart of the method of the body. Please refer to FIG. 1 and FIG. 2 at the same time. In this embodiment, the dummy 5 stores a storage list of the IP address of the network segment of the specific network segment 201025134 J4.TW 30127twf.doc /n The sub-processing unit 140, which has been inserted into the storage unit interface ls, is then inserted into the sub-processing unit 140 of the sub-processing unit to obtain the Bob and segment Ip addresses recorded by the storage unit through the main processing unit 110. When the unit 140 is ready to start the firmware update procedure, first, as shown in step 210, the sub-processing unit M transmits the update request message to each of the electronic devices in the network segment. Further, the sub-processing unit 140 The update request message will be broadcasted in the corresponding segment according to the network segment positive address obtained from the storage unit. * In order to avoid that the electronic device in the network segment does not receive the broadcast update request message due to the network mais, in an embodiment, the sub-processing unit 140 repeats the network according to a broadcast retransmission interval (for example, i seconds). The segment updates the request message n times, where 11 is a positive integer. For example, the sub-processing unit 140 repeats the broadcast update request message 3 times, and the time interval of each broadcast is! second. In this way, the possibility that the electronic device in the network segment misses the update request message can be reduced as much as possible. In this embodiment, after receiving the update request message transmitted by the sub-processing unit 140, each electronic device will return an update back to the device 1 to update the device 1 (10). Regardless of whether the sub-processing unit 140 repeatedly transmits the update request message to the electronic device, the electronic device will only return an update reply message 'and avoid occupying too much wireless network bandwidth.

In the update of the initial body (four) packet resend interval. In an embodiment, the sub-process, 70 140 will take the maximum of the above differences and use the product of the maximum value and the value of the value (e.g., 0.75) as the packet retransmission interval. In the embodiment, the sub-processing unit 14 can receive the update signal of the electronic device, and then learn the network signal strength value of the electronic device. The sub-processing unit 14G will randomly collect the number of packet resends to the electronic device according to the magnitude of the network signal strength value. For example, the value of the network number of the electric device indicates that the number of retransmissions may be lower because of the network=stable (four) message or the lower rate of information. On the other hand, in order to avoid the electronic farms with small values of the strength of the ugly signal, the message or information is missed due to various network conditions, the sub-processing list 12 201025134 ---------4.TW 30127twf.doc/n yuan 140 One such electronic device will be given. In this embodiment, the number of packet retransmissions is, for example, 2 2 retransmission times. However, this is only one of the eleven examples of the present invention, not between the five. Without limiting the present invention, after the packet is re-segmented with each electronic device, then as shown in step 240, the sub-process = 1 is divided into a plurality of packets according to their sizes, and according to ^ = to each electronic device. In this embodiment, the delivery of each packet to each electronic device 2G will sequentially select one of the packets in the order of 4, and in the interval of each interval - the interval of the packet retransmission interval The selected packet is transmitted to each electronic device 2 until the number of times the packet is sent has reached the packet re-delivery disk of the electronic device. * The receiver selects another packet again, and according to the packet resend room & The packet is repeatedly transmitted to each (four) sub-device. ❿ After the packet is also transmitted, the device that last updated in step 25 〇 I ’ ’ will wait for the update success message from each electronic device. The sub-processing unit (10) = the update operation of the electronic device that has transmitted the update success message every time the update success message is received. It is worthwhile to mention that in this implementation, each electronic device will only update the actual body after receiving the last -_ packet, and judge whether the update is successful using the received financial package (4) (four) update is only in the more In the case, the electronic device f returns the update success message. In addition, in order to prevent the electronic device from returning the update success message at the same time, the electronic device may wait for a delay time after the update is successful to transmit the update success message. The delay time may be determined according to the random number or may be different according to the value of the network signal strength detected by the electronic device. Through the update success message returned by each electronic device, the firmware update device 100 can determine which electronic devices in the network segment have successfully updated the firmware. Since the update success message returned by the electronic device is received only after the last packet is transmitted, it can be ensured that the process of updating the network is not interrupted, and then speeds up, and 3 is another according to the present invention. - An example of the updated '^ block diagram of the Lexus.
