Abstract
The invention provides a software online upgrade method, which comprises the following steps that by mainly utilizing the principle of incremental upgrade, on the basis of establishing the communication between a host computer and a slave computer, the host computer searches the corresponding software data of the queried software version information at the host computer terminal by querying the software version information of an embedded system running in the slave computer, finds the changed part of the data by comparing the searched software data with pre-upgrade software data, and determines whether the changed range of the found changed part of data exceeds a preset changed range, otherwise, the host computer sends the found changed part of data to the slave computer, so that the slave computer performs the online upgrade operation according to the changed part of data in an incremental upgrade way, and thus the incremental upgrade function in online upgrade of the embedded system software is realized, and the upgrade efficiency can be effectively improved.
Description
Technical field
The present invention relates to a kind of on-line software updating method, particularly relate to a kind ofly in order to solve in the little situation of the pre-upgrade software of embedded system and existing software change, how by increment upgrading mode, improve the on-line software updating method of the problem of built-in system software online upgrading efficiency.
Background technology
In order to make the informations such as software in embedded system, data in last state, need in real time embedded system to be carried out to upgrade maintenance, and the built-in system software online upgrading method of using in the industry is at present by the full content of upgrade software being carried out to complete upgrading, all softwares of upgrading successively in embedded system from the beginning to the end namely, under this upgrading mode, escalation process is chronic, can not meet the demand of built-in system software real-time update.
And, after embedded system is used, because hardware is fixing, most software upgradings just solve a small amount of defect existing in current software, namely on existing basis of software, have a small amount of change, the content of its actual upgrade seldom, in this case, if still carry out the complete upgrading of whole softwares, escalation process is longer, efficiency is very low, affects client and uses.
Therefore,, based on above deficiency, be necessary to provide a kind of and can shorten in right amount by situation the on-line software updating method of escalation process, to improve the efficiency of online upgrading.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide and a kind ofly can shorten in right amount by situation the on-line software updating method of escalation process.
For achieving the above object and other relevant objects, the invention provides a kind of on-line software updating method, between its host computer and slave computer that is applied to intercom mutually, for realizing the online upgrading to the built-in system software of slave computer, wherein, described host computer is pre-stored have the software data of pre-upgrading, various software version information and with each software version information software data not of the same race one to one, it is characterized in that, described on-line software updating method at least comprises: (1) sets up communicating by letter between described host computer and described slave computer; (2), in described upper computer end, to described slave computer, send software version query statement; (3) in described slave computer end, respond the instruction that described host computer sends, and upload software version information that this slave computer uses to described host computer; (4), in described upper computer end, the software version information of uploading according to described slave computer is searched the whether pre-stored software data corresponding with this software version information that have in this host computer, if, proceed to step (5), if not, proceed to step (6); (5) in described upper computer end, the software data of searched software data and the pre-stored pre-upgrading of this host computer is compared, and look for the part that data have change, and the data that judgement is looked for have the scope that the part of change changes whether to exceed a default change category, if, proceed to step (6), if not, sending the data of being looked for has the part of change to described slave computer, has the part of change to carry out online upgrading operation in increment upgrading mode for slave computer according to these data; And (6) are in described upper computer end, send the software data of the pre-stored complete pre-upgrading of this host computer to described slave computer, for slave computer, according to this pre-software data of upgrading, in complete upgrading mode, carry out online upgrading operation.
Preferably, above-mentioned steps (1) further comprises: by RS232, RS485 or network, set up communicating by letter between described host computer and described slave computer.Wherein, described network can be for example wireless network or cable network.Described software version information comprises software version number, device number and device type.
In an embodiment of on-line software updating method of the present invention, described on-line software updating method is supported breakpoint transmission function.
In another embodiment of on-line software updating method of the present invention, described on-line software updating method is supported broadcast communication pattern.
As mentioned above, on-line software updating method of the present invention is mainly the principle of having utilized increment upgrading, at host computer and slave computer, set up on the basis of communicating by letter, make host computer by inquiring about the software version information of the embedded system of moving in slave computer, afterwards in the upper computer end search software data corresponding with inquired software version information, and searched software data and the software data of pre-upgrading are compared, look for data and have the part of change, and the data that judgement is looked for have the scope that the part of change changes whether to exceed a default change category, if not, send the data of being looked for and have the part of change to slave computer, for slave computer, according to these data, there is the part of change to carry out online upgrading operation in increment upgrading mode, can improve upgrading efficiency like this, realized the function of increment upgrading in built-in system software online upgrading, simultaneously, retained selectively again the possibility of complete upgrading, in host computer, do not search the software data corresponding with inquired software version information, or the software data of the software data searching and pre-upgrading compares under the situation that rear variation exceeds default change category, slave computer is carried out to complete upgrading, and then guaranteed the integrality of software upgrading.
