Abstract
The invention relates to the technical field of distribution transformer detection, in particular to a method for downloading and updating programs of a distribution transformer monitoring terminal, which includes steps of downloading a program package, decompressing the program package to an assigned address, restarting for updating and the like. The method only uses intrinsic functions of a terminal chip without increasing terminal complexity and cost.
Description
Technical field
The present invention relates to the power transformer detecting technical field, relate in particular to a kind of program down loading updating method of distribution transformer monitoring terminal.
Background technology
In electrical power distribution system, substation transformer is a power equipment of voltage directly being distributed to low-voltage customer, and its service data is the important component part of whole power distribution network basic data, and whether good whether these data normally be power distribution network operation important reflection.And distribution transformer monitoring terminal is used for monitoring in real time the operating various parameters of substation transformer exactly; Data according to gathering are carried out statistical study; Find the abnormal conditions of substation transformer emerged in operation in time and control timely or solves, can realize that stable, the optimization of electrical network moves.Distribution transformer monitoring terminal when defective appears in the installed device program, when perhaps the user has proposed new demand, need carry out remote update to terminal program as the built-in terminal product simultaneously, to guarantee the correctness of terminal operating.
The method for updating program of prior art distribution transformer monitoring terminal mainly contains two kinds: 1, adopt embedded real-time operating system; This method has mainly increased the requirement to memory capacity; So need to change the bigger hardware of memory capacity, increased hardware cost; 2, adopt the method that increases the outer control programming system, this method has not only reduced the reliability at terminal itself, and has increased the complexity and the cost at terminal.So these two kinds of methods are not the best approaches.
Summary of the invention
Technical matters to be solved by this invention is: provide a kind of to utilize the function of terminal chip itself and do not increase the program down loading updating method of the distribution transformer monitoring terminal of terminal complexity and cost.
The technical scheme that the present invention adopts is: a kind of program down loading updating method of distribution transformer monitoring terminal, and it is characterized in that: it may further comprise the steps:
Whether inspection existed the program updates sign when (1) terminal program started, if do not exist updating mark then to get into next step, if exist updating mark then to jump to step (6);
(2) if normal working procedure when receiving the condensing routine bag that main website sends over, gets into next step, does not then continue normal working procedure if receive;
(3) receive the condensing routine bag, and the condensing routine bag is stored in the external memory storage of correspondence position on the terminal chip, get into next step then;
(4) whether inspection condensing routine bag receives fully, fully then gets into next step if receive, and does not fully then jump to step (3) if receive;
(5) add the program updates sign, preserve data, jump to step (11) then
(6) call refresh routine, get into next step then;
(7) from the external memory storage of terminal chip, take out the condensing routine bag,, get into next step then then to its decompress(ion);
(8) application program in the internal storage of terminal chip is wiped, will separate the program copy that presses then in the internal storage of terminal chip, get into next step again;
(9) whether detection condensing routine bag is all got and is over, if getting to be over then gets into next step, does not then jump to step (7) if got;
(10) clear program updating mark gets into next step then;
(11) restart, promptly jump to step (1).
As preferably, described terminal chip model is LPC2378.
The program down loading updating method of a kind of distribution transformer monitoring terminal of the present invention compared with prior art has following significant advantage and beneficial effect:
This method makes full use of the function of terminal inner chip itself, does not increase the complicacy of peripheral components and system, has practiced thrift cost, and can well accomplish the down loading updating task of program.
Description of drawings
Accompanying drawing is the process flow diagram of the program down loading updating method of distribution transformer monitoring terminal of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done to further describe, but the present invention is not limited only to following embodiment.
Shown in accompanying drawing, a kind of program down loading updating method of distribution transformer monitoring terminal, it is characterized in that: it may further comprise the steps:
Whether inspection existed the program updates sign when (1) terminal program started, if do not exist updating mark then to get into next step, if exist updating mark then to jump to step (6);
(2) if normal working procedure when receiving the condensing routine bag that main website sends over, gets into next step, does not then continue normal working procedure if receive;
(3) receive the condensing routine bag, and the condensing routine bag is stored in the external memory storage of correspondence position on the terminal chip, get into next step then;
(4) whether inspection condensing routine bag receives fully, fully then gets into next step if receive, and does not fully then jump to step (3) if receive;
(5) add the program updates sign, preserve data, jump to step (11) then
(6) call refresh routine, get into next step then;
(7) from the external memory storage of terminal chip, take out the condensing routine bag,, get into next step then then to its decompress(ion);
(8) application program in the internal storage of terminal chip is wiped, will separate the program copy that presses then in the internal storage of terminal chip, get into next step again;
(9) whether detection condensing routine bag is all got and is over, if getting to be over then gets into next step, does not then jump to step (7) if got;
(10) clear program updating mark gets into next step then;
(11) restart, promptly jump to step (1).
Described terminal chip model is LPC2378.
The practical implementation step of the program down loading updating method of distribution transformer monitoring terminal of the present invention: at first be to start terminal program, detection is enough to have the program updates sign, if there is not the program updates sign, and then normal working procedure.When normal working procedure, receiving the condensing routine bag that main website sends over; The condensing routine bag can be accepted in the terminal; Be stored in it in the external memory storage of correspondence position on the terminal chip then, and then check whether the condensing routine bag has received fully, accept and store if do not receive fully then continue; If received complete then add the program updates sign, preserve data and restart.Just start terminal program after restarting, begin inspection again and whether have the program updates sign, because added the program updates sign just now; So there is the program updates sign, call refresh routine then, take out the condensing routine bag in the external memory storage from terminal chip; These condensing routine bags of decompress(ion) are then removed the program that is applied in the internal storage in the terminal chip afterwards earlier, then will separate in the program copy that the presses internal storage in the terminal chip; Whether detect the condensing routine bag has more got and has been over; If do not got, continuation taking-up condensing routine bag decompress(ion) then duplicates, and is over if get; Then the clear program updating mark restarts then.Still can detect after restarting specifically and whether have the program updates sign; Because wiped the program updates sign just now; Do not have the program updates sign specifically; Program just can normally have been moved, if main website does not send the condensing routine bag that upgrades usefulness, then the program at terminal will normally be moved always.
