The invention discloses embedded equipment and an on-line updating system and a method of a firmware in embedded equipment. The embedded equipment comprises a storage module, a downloading module and a guidance loading module, wherein, the storage module comprises a current operating firmware storage area and a firmware mapping file storage area; the downloading module is used for downloading the firmware mapping file of which the downloading edition is superior to that of the current operating firmware, and storing the firmware mapping file into the firmware mapping file storage area; and the guidance loading module is used for loading and calling the firmware mapping file. The embedded equipment and the on-line updating system and the method of the firmware in the embedded equipment of the invention are characterized in that by adopting the method, the firmware mapping file is downloaded from a server via a network and stored into the corresponding storage area; and after the system is restarted, the firmware mapping file is guided to load. Compared with the prior art, the invention simplifies the firmware updating steps, improves updating speed and success rate, lowers updating cost and prolongs the service life of the embedded equipment.

The invention discloses a method for upgrading a video camera. The method upgrades the video camera by using a transmission upgrade packet of a reverse blanking zone, prevents disassembly, and achieves simple operation and low upgrade cost. After receiving a upgrading instruction sent from a rear end and switches a normal operating mode to a upgrading mode but before transmitting a response signal to the rear end, a front-end video camera sets an initial valid data zone and an initial reverse blanking zone in the normal operating mode as reverse blanking zones, namely increases the number of rows of the reverse blanking zone. Thus, when receiving the upgrading packet sent from the rear end via the reset reverse blanking zone, the front-end video camera may increase the transmission capability and speed of the reverse blanking zone so as to increase the upgrading speed of the video camera. Additionally, after upgrading is completed, the front-end video camera restores the initial valid data zone and the initial reverse blanking zone in order not to influence the normal operation of the front-end video camera after the upgrading.

The invention provides a differential file generation method and an upgrade method and system based on a differential file, and belongs to the technical field of terminal upgrade. The differential file generation method comprises the steps that an index is established for an old upgrade file and used for searching for a reusable data segment; a new upgrade file and the old upgrade file are analyzed, and a perfectly-matched area of the new and old upgrade files is obtained; with the perfectly-matched area as an interval and a set difference as a standard, areas with a certain proportion of similar content are expanded leftwards and rightwards respectively and are merged and recorded with the perfectly-matched area into a DIFF area, and other parts are recorded into an EXTRA area; the difference file is generated, wherein the difference file comprises a file description header and three compressed data segments. The invention further provides the upgrade method and system based on the differential file. The differential file generation method and the upgrade method and system based on the differential file have the advantages that by adopting a high-compression differential algorithmand just downloading a difference part, firmware upgrade can be completed, the upgrade flow consumption is reduced, and the upgrade speed is greatly increased.

The invention discloses a differential package manufacturing method and device. The differential package manufacturing method comprises the following steps: determining target files in a new version file package and source files in an old version file package; respectively determining unique identifiers of the target files and the source files before decompression; decompressing the target files and the source files with different unique identifiers; determining whether the decompressed target files and the decompressed source files are the same; and if so, eliminating the target files the same as the source files, and manufacturing the target files different from the source files into a differential package. By adopting the differential package manufacturing method and device disclosed by the invention, files requiring no processing can be eliminated, thereby reducing the size of an upgrading package and accelerating the upgrading speed.

The invention relates to a method for upgrading a firmware of an advertising machine terminal through a USB (Universal Serial Bus) interface. The method comprises the following steps: (S01) connecting a USB flash disk to a PC (Personal Computer), uploading a firmware program to be upgraded to the USB flash disk through upper computer application software, and setting display parameters and an upgrading mark of the advertising machine terminal under the support of the upper computer application software; (S02) after the advertising machine terminal is electrified and started, judging the upgrading mark and upgrading the firmware program to be upgraded; and (S03) after the firmware program is successfully upgraded, automatically reloading a new firmware program by the system of the advertising machine terminal. The method is suitable for upgrading the firmware of big and small advertising machines in various places only by using one USB flash disk; moreover, the firmware can be divided into a plurality of sub areas and the sub areas can be correspondingly upgraded according to specific revised parts without upgrading the whole firmware program again every time; therefore, the upgrading speed is increased, and the error probability is reduced.

The invention discloses a method for remote differential upgrading of electric energy meter embedding type software. The method comprises the following steps of enabling a client to compare with the latest software version information and the software version information obtained from an electric energy meter, so as to obtain differential data information; enabling the client to send a generated toggling and upgrading command to the electric energy meter; enabling the electric energy meter to send toggling operation result information generated by executing of the toggling and upgrading command to the client; if the toggling is successful, enabling the client to traverse and calculate a first CRC (cyclic redundancy check) sum of an application code of the latest software version information; enabling the client to send the differential data information to the electric energy meter, and after the sending is completed, sending an upgrading completing command to the electric energy meter; enabling the electric energy meter to perform upgrading processing according to the differential data information and the updating completing command. The invention also discloses a system for the remote differential upgrading. The method has the advantage that the program upgrading of the electric energy meter is completed by the client, and the electric energy meter is upgraded according to the differential data information, so the manual cost is reduced, and the technical effect that the upgrading speed is improved is achieved.

The embodiment of the invention provides a vehicle upgrading method and device, and the method is based on a preset vehicle upgrading architecture, the preset vehicle upgrading architecture comprisesan upper computer for online upgrading, a central gateway, and a plurality of communication channels, and the plurality of communication channels are respectively connected with the upper computer through the central gateway. The method comprises the steps of enabling the upper computer to obtain a to-be-upgraded ECU list for a to-be-upgraded vehicle, wherein the to-be-upgraded ECU list comprisesa plurality of to-be-upgraded ECUs; determining a communication channel corresponding to each ECU to be upgraded according to the list of the ECUs to be upgraded; and upgrading the ECUs to be upgradedin parallel through the corresponding communication channels. The upgrading strategy of the multi-channel ECU parallel software is completed based on the multiple communication channels, the whole vehicle software upgrading speed is increased, the software upgrading success rate is increased and the vehicle power consumption is reduced by shortening the vehicle software upgrading time, and the unnecessary upgrading waiting time is shortened.
