Step S50: railroad track monitoring sensing access and multiplexing device 1 sends edition data request message to railroad track monitoring sensing network controller 1, carries the firmware version identifier that application loads in edition data request message.
Step S51: railroad track monitoring sensing network controller 1 sends edition data response message to railroad track monitoring sensing access and multiplexing device 1, carry length word joint number and the start-up loading mark of firmware version file to be loaded in message, represent version transmission start.
Step S52: railroad track monitoring sensing network controller 1 sends edition data request message to railroad track monitoring sensing access and multiplexing device 1, carries version information block in message.Because a firmware version file far more than a carry-on data length of edition data request message, therefore can cannot transmit all versions file content by an edition data request message usually.Firmware version file needs to be divided into multiple version information block, carries one of them version information block in each edition data request message.
Step S53: railroad track monitoring sensing access and multiplexing device 1 sends edition data response message to railroad track monitoring sensing network controller 1, object code in message is set to 0, represents the version information block successfully received in previous release data request information.
Step S54: repeat step S52 and step S53, until all data of described version file all download in railroad track monitoring sensing access and multiplexing device 1.
Step S55: railroad track monitoring sensing network controller 1 sends edition data request message to railroad track monitoring sensing access and multiplexing device 1, carry version in message and send end mark, represent that all version information blocks of described firmware version file have all sent railroad track monitoring sensing access and multiplexing device 1 to.
Step S56: railroad track monitoring sensing access and multiplexing device 1 sends edition data response message to railroad track monitoring sensing network controller 1, and the object code in message is set to 0, represents that version transport process is successfully completed.
Below, be described a seventh aspect of the present invention, wherein, Fig. 1 and associated description thereof are incorporated herein by reference.
Edition data request message is used to upgrade the firmware version on railroad track monitoring sensing access and multiplexing device.The information carried in edition data request message comprises two territories: edition data, version identifier.Wherein:
Edition data territory comprises edition data information and edition data block, and it comprises two parts: operation code territory and codomain.Operation code domain representation transmission command code, operation code territory is that 1 expression edition data is comprised in this message; Operation code territory is that last edition data block of 2 expressions is comprised in this message; Operation code territory is that 5 expressions a mistake occur, version bust this.Codomain is made up of 1024 bytes at most, and edition data block content is comprised in codomain.When the value in operation code territory is 5, codomain is empty.
For representing, version identifier requires that the firmware version that sensing access and multiplexing device runs monitored by railroad track.
Edition data request message transmits between railroad track monitoring sensing access and multiplexing device and railroad track monitoring sensing network controller, monitors sensing access and multiplexing device for transmitting a new firmware version to railroad track.After railroad track monitoring sensing access and multiplexing device or railroad track monitoring sensing network controller receive an edition data request message, its meeting edition data response message is replied.
Below, be described a eighth aspect of the present invention, wherein, Fig. 1 and associated description thereof are incorporated herein by reference.
Edition data response message is for confirming the edition data request message received, and the information carried in edition data response message comprises: object code, version information, start-up loading information.Wherein:
Object code represents that whether the previous edition data request message received is effective.Wherein: 0 represents successfully; 14 represent that firmware version error in data (reason is verify unsuccessfully), 15 represents that firmware version error in data (reason is invalid data length), 16 represents that firmware version error in data (reason is other mistakes), 17 represents firmware version error in data (reason is that software version exists).
Version information comprises version file length and edition data block, and it comprises two subdomains: file size, version information block, and file size subdomain represents the length word joint number of the version file loaded, and version information block subdomain comprises the block of information of release content.
Start-up loading information is used for notifying that railroad track monitoring sensing access and multiplexing device starts a firmware version document transmission process by railroad track monitoring sensing network controller.
Below, be described a ninth aspect of the present invention, wherein, Fig. 1 and associated description thereof are incorporated herein by reference.
Railroad track monitoring sensing access and multiplexing device reset request message is used to notify that a railroad track monitoring sensing access and multiplexing device performs and restarts operation, and the information carried in message comprises: version identifier.Version identifier is sent to railroad track to monitor sensing access and multiplexing device by railroad track monitoring sensing network controller and points out to require that railroad track monitoring sensing access and multiplexing device restarts the firmware version of rear operation.
Below, be described a tenth aspect of the present invention, wherein, Fig. 1 and associated description thereof are incorporated herein by reference.
Railroad track monitoring sensing access and multiplexing device reset response message is the confirmation to railroad track monitoring sensing access and multiplexing device reset request message.Once railroad track monitoring sensing access and multiplexing device receives railroad track monitoring sensing access and multiplexing device reset request message, it at once forwarding railway railway monitoring sensing access and multiplexing device reset response message confirm.The information carried in railroad track monitoring sensing access and multiplexing device reset response message comprises: object code.Object code represents the result that reset request performs, and wherein: 0 represents successfully, 10 expressions are restarted unsuccessfully (can not restart), and 11 expressions are restarted unsuccessfully (firmware write error).
When after the railroad track monitoring sensing access and multiplexing device reset request message that railroad track monitoring sensing access and multiplexing device 1 receives from railroad track monitoring sensing network controller 1, it is replied with a railroad track monitoring sensing access and multiplexing device reset response message, then restarts.If railroad track monitoring sensing access and multiplexing device 1 can not write its nonvolatile storage, guarantee that it runs the firmware version pointed out in version identifier, it can identify unsuccessfully (as: object code=11) by the object code that railroad track is monitored in sensing access and multiplexing device reset response message, but must restart.
If railroad track monitoring sensing access and multiplexing device 1 can not be restarted, its forwarding railway railway monitoring sensing access and multiplexing device reset response message to railroad track monitoring sensing network controller 1, and comprises the object code (as: object code=10) pointing out failure cause.After receiving this message, railroad track monitoring sensing network controller 1 will no longer for railroad track monitoring sensing access and multiplexing device 1 provides network insertion and controls service.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improves, all should be included within protection scope of the present invention.
