step S2: adding a backup storage file into the new self-research RTOS, wherein the storage space of the backup storage file is consistent with the storage space of the sub-executable file with the largest storage space;
step S3: the remote upper computer establishes connection with the POS equipment through a network;
step S4: the remote upper computer sends a down character string to inform the POS equipment of entering a downloading mode;
step S5: the POS equipment receives the down character string and returns a confirmation to inform the remote upper computer;
step S6: the remote upper computer transmits a new modx character string to the POS equipment to inform that an x-th sub-executable file in the plurality of sub-executable files needs to be updated;
step S7: the POS equipment receives the mod x character string and returns an acknowledgement to inform the remote upper computer;
step S8: the remote upper computer transmits a modx sub executable file to be updated to the POS equipment;
step S9: the POS equipment receives the mod x sub-executable file and returns an acknowledgement to inform the remote upper computer;
step S10: the POS equipment stores the received mod x sub-executable file in a backup storage file and checks the backup storage file;
step S11: after verification is completed, the POS equipment erases the content in the original x sub-executable file and replaces the content by the updated content of the backup storage file to form an updated x sub-executable file;
step S12: the POS equipment erases the content in the backup storage file and returns a confirmation to inform the remote upper computer that the updating is completed;
step S13: the remote upper computer is disconnected with the POS equipment.
Preferably, the storage space of a plurality of the sub-executable files is 50kb.
Preferably, the storage space of the backup storage file is 50kb.
Preferably, the number of the sub-executable files is set to 5.
Preferably, the remote upper computer establishes connection with the POS device in a wireless mode or a wired mode.
Compared with the prior art, the method for remotely and incrementally updating the self-grinding RTOS has the following advantages:
by cutting the self-grinding RTOS into a plurality of sub-executable files from one whole, only a modified sub-executable file is updated during remote updating, and other executable files are kept unchanged, so that the load capacity of one remote updating is only the size of a sub-executable file, which is beneficial to improving the remote updating efficiency, reducing the possibility of updating failure, and the updating can be completed by needing less remote communication data flow, thereby being beneficial to reducing the communication cost, and meanwhile, the spare storage space of the POS equipment to be updated also only needs the size space of a certain executable file, without providing the spare storage space consistent with the memory of the whole self-grinding RTOS, thereby being beneficial to reducing the requirement on the spare storage space of a large memory and reducing the cost on hardware.
[ description of the drawings ]
FIG. 1 is a flow chart showing a method for remote incremental updating of a self-polishing RTOS according to the present invention.
[ detailed description ] of the invention
The present invention will be described in further detail with reference to the accompanying drawings and examples of implementation in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to fig. 1, the present invention provides a method for remote incremental update of a self-lapping RTOS, comprising the steps of:
step S1: the original self-grinding RTOS of the POS equipment is divided into a plurality of sub-executable files by the whole executable files according to the function modules so as to form a new self-grinding RTOS.
Specifically, by cutting the larger self-grinding RTOS into a plurality of sub-executable files, one sub-executable file can be updated without updating all the sub-executable files during updating, which is beneficial to improving the updating speed and reducing the time and telecommunication cost for updating.
Preferably, in the present invention, the number of sub-executable files is set to 5 and the storage space is 50kb.
Step S2: and adding a backup storage file into the new self-research RTOS, wherein the storage space of the backup storage file is consistent with the storage space of the sub-executable file with the largest storage space.
The backup storage file is set, so that the remote upper computer can not update the sub-executable file directly, and the possibility that the updated function cannot be realized due to direct update to the sub-executable file when the update content in the remote upper computer is problematic is reduced.
The storage space of the backup storage file is consistent with the storage space of the sub executable file with the largest storage space, so that the situation that the updating is stopped or failed because the memory occupied by the updated content is larger than the storage space of the backup storage file does not occur in the updating process, the smooth progress of the updating progress is ensured, and the possibility of increasing the hardware cost because the storage space of the backup storage file is overlarge is avoided.
Preferably, the storage space of the backup storage file is 50kb.
Step S3: the remote upper computer establishes connection with the POS equipment through a network.
Preferably, the remote upper computer and the POS device are connected in a wireless mode or a wired mode, and the connection can be specifically set according to actual practice.
Step S4: the remote upper computer sends a down character string to inform the POS equipment of entering a downloading mode;
step S5: the POS equipment receives the down character string and returns a confirmation to inform the remote upper computer;
step S6: the remote host computer issues a new modx string to the POS device to inform that the x-th sub-executable file in the plurality of sub-executable files needs to be updated.
It will be appreciated that the xth sub-executable may be the first, last or any one of the sub-executables, particularly according to
Step S7: the POS equipment receives the modx character string and returns a confirmation to inform the remote upper computer;
step S8: the remote upper computer transmits a modx sub executable file to be updated to the POS equipment;
step S9: the POS equipment receives the modx sub executable file and returns an acknowledgement to inform the remote upper computer;
step S10: the POS device stores the received modx sub executable file in the backup storage file and performs verification.
Step S11: after verification is completed, the POS equipment erases the content in the original x sub-executable file and replaces the content by the updated content of the backup storage file to form an updated x sub-executable file;
step S12: the POS equipment erases the content in the backup storage file and returns a confirmation to inform the remote upper computer that the updating is completed;
step S13: the remote upper computer is disconnected with the POS equipment.
Compared with the prior art, the method for remotely and incrementally updating the self-grinding RTOS has the following advantages:
by cutting the self-grinding RTOS into a plurality of sub-executable files from one whole, only a modified sub-executable file is updated during remote updating, and other executable files are kept unchanged, so that the load capacity of one remote updating is only the size of a sub-executable file, which is beneficial to improving the remote updating efficiency, reducing the possibility of updating failure, and the updating can be completed by needing less remote communication data flow, thereby being beneficial to reducing the communication cost, and meanwhile, the spare storage space of the POS equipment to be updated also only needs the size space of a certain executable file, without providing the spare storage space consistent with the memory of the whole self-grinding RTOS, thereby being beneficial to reducing the requirement on the spare storage space of a large memory and reducing the cost on hardware.
