Description
Technical field
The invention belongs to printing device control technology and equipment control field, be specifically related to a kind of method of printing device being carried out auto-update by the Internet.
Background technology
In the prior art, the program of equipment end operation generally all is stored in the read only memory ROM on the equipment, in the time of need upgrading to equipment, actually just the firmware that is stored in the read only memory ROM is upgraded.
ROM upgraded dual mode: a kind of is by specific programming program and specific fever writes hardware the ROM on the equipment plate card to be carried out the firmware programming, and this mode can only be upgraded by on-the-spot mode; Another kind is that the program with programming ROM also is stored among the ROM, and ROM programming program is in service at ROM in the time of upgrading, and ROM is upgraded.The second way has been saved special-purpose hardware such as ROM fever writes, integrated ROM fever writes on the device controller in other words, and this mode provides the possibility of firmware being carried out remote upgrade.
The ROM of existing equipment is made of the Flash flash memory.The advantage of Flash flash memory is can repeat to write, and can preserve data lastingly after the outage.Existing printing device also uses the Flash flash memory as read only memory ROM usually.The programming of Flash flash memory is to cause the specific tube human hair combing waste of Flash chip to give birth to specific high-low level sequence by programmable device or CPU, thereby order such as realizes wiping, writing.The Flash flash memory also has characteristics, be exactly that each operation can only be operated certain bulk zone, if revise the data of certain address, at first to wipe all data in the affiliated data block of these data, promptly value all becomes 1, new data monoblock could be write then, like this, if a certain blocks of data has occurred in the process that writes unusually, the monoblock data all can make a mistake so.
Upgrade data derives from the Internet Internet usually, sends to equipment by device drives then, and the existing firmware of equipment end wants can accept to drive the upgrade data of sending.
As previously mentioned, in the general read only memory ROM that also all is stored on the equipment of the program of printing device end operation at present, when printing device need be upgraded, reality was just upgraded to the firmware that is stored in the read only memory ROM.The read only memory ROM of the print control unit in printing device comprises three partial contents: 1) be positioned at the boot code area of zero-address, 2) zone that exists of the operating system of controller operation, 3) zone that exists of control program in the printing device controller.Except guidance code will not be upgraded, other two operating systems and control program can be upgraded, and bootcode upgrade is nonsensical, and guidance code is just inoperative because printing device is moved the back, does not influence the characteristic of printing device.It is the upgrading of printing device control program that upgrading is used maximum, because control program has determined the running status of printing device, and operating system nucleus is seldom upgraded.
Because the development of printing device is very rapid, printing device usually needs to upgrade, and promptly needs the firmware in the read only memory ROM is upgraded.But the method for at present printing device equipment being upgraded is not very desirable, and weak point is all arranged.Existing method has following several:
The problems that may exist some to hide when (1) equipment such as printing device dispatches from the factory, these problems of hiding can come out gradually in practice in the future, for the present common way of hardware device is product recall, perhaps provides the service technician of manufacturer to the user there modes such as printing device replacing control card to be upgraded by equipment.This method need consume lot of manpower and material resources, and the product of upgrading also needs long time, is especially sold to abroad when equipment, and expense and time loss increase especially.
(2) present, most of printing device often do not have wrong control to wait measure in upgrading, tend to cause the upgrading failure when sudden serious situation such as sudden power occurring, cause the full detail of equipment to lose simultaneously, collapse takes place and can't oneself restart in system as a result.Common way is the ROM programming again with printing device now, but, this needs technician's site disposal, and generally to carry out programming again to the ROM in the equipment by special programming instrument, so, can not guarantee fully success when printing device is upgraded and need technician's execute-in-place.
(3) the current software systems that have also can be upgraded by the Internet, carry out patch installing and upgrade but only limit to software, but not to equipment firmware by the Internet upgrading.
Summary of the invention
At the defective that exists in the prior art, the purpose of this invention is to provide a kind of method of printing device being carried out auto-update by the Internet, this method can make printing device can realize remote upgrade by the Internet, and can also upgrade again for unexpected upgrading failure, system crash can be do not caused, thereby cost can be raised the efficiency and save greatly.
For reaching above purpose, the technical solution used in the present invention is: a kind ofly by the Internet printing device is carried out the method for auto-update, may further comprise the steps:
(1) printing device directly or by computing machine and the Internet is connected;
(2) printing device is collected printing device manufacturer automatically by the Internet and is left up-to-date printing device controller information on the device server in, judges whether and upgrade;
(3) if printing device needs upgrading, then the binary file of downloading up-to-date equipment firmware from the vendor equipment server to local computer that printing device directly links to each other on or on the direct random access memory (RAM) to the printing device controller;
(4) printing device begins upgrading, and printing device starts escalation process automatically, will download to equipment firmware binary file after the local renewal by in the read only memory ROM of the programming program burn writing in the print control unit in the printing device controller;
(5) after in the ROM (read-only memory) of new firmware binaries file programming in the printing device controller, verify its check code, if correct, revise the new firmware program start address of pointed of boot code area;
(6) restart printing device, the printing device control program of operation just starts program after the new upgrading according to the pointer after upgrading, thereby finishes the upgrading of printing device.
Furthermore, have better effect, in the step (4), the printing device control program in the ROM (read-only memory) of print control unit is upgraded for making the present invention;
In the step (4), in the ROM (read-only memory) ingredient of printing device controller,, the block size backup zone suitable with the printing device control program is set in order to realize faultless upgrading;
In the step (4), the read only memory ROM in the printing device controller is made of Flash flash memory, PROM or PPROM, preferably is made of the Flash flash memory.Realize programming by the high-low level sequence that allows the ordinary procedure operation time simulate the specific pin of Flash flash memory to the read only memory ROM in the printing device controller.
Further, in the step (5), in order to handle extreme cases such as outage in whole upgrade process, may occur, the ROM (read-only memory) of printing device controller can be divided into boot code area, the zone that operating system exists, zone and standby four zones, clear area that the printing device control program exists, in upgrading, new data recycle Flash in three zones except guidance code, the in store effective pointer that is writing down that zone of while boot code area, when printing device begins to upgrade, the upgrading routine can be new upgrade data that the binary file programming of up-to-date equipment firmware is to that idle zone, after programming is finished, check verification and, if confirm the programming success, upgrade the pointer in the guidance code.
Further, for making the present invention have better effect, in the step (5), in order to prevent the programming mistake of Flash, can carry out verification and inspection to the content of programming, and during the pointer in upgrading final step modification guidance code, can not adopt the pointer double copies for mistake appears in the modification that guarantees pointer, and each pointer to be enclosed its update date.
Effect of the present invention is: adopt method of the present invention, can realize remote upgrade to printing device, can put the deficiency of finding the back on market in printing device upgrades to printing device under the situation minimum to customer impact, if and upgrade to fail and also can upgrade again, raise the efficiency and reduced the upgrade maintenance cost of printing device greatly.

Embodiment
The invention will be further described below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2 and shown in Figure 3, a kind ofly printing device is carried out the method for auto-update by the Internet, may further comprise the steps:
(1) printing device and the Internet connect, and connect to be divided into two kinds: a kind of is that printing device itself is exactly a network print apparatus, and promptly the controller of printing device itself has and being connected of network; Another kind is that printing device connects by computing machine and the Internet that connects with it, and upgrade data is sent to printing device by the Internet; What describe in the present embodiment is second kind of situation, and first kind of situation is similar, and the principle of the two is consistent;
(2) printing device is collected the up-to-date printing device controller information on the device server of printing device manufacturer automatically by the Internet, judges whether and upgrade.When the computing machine that is connected with the Internet receives the new upgrade notification of printing device manufacturer, at first inquire about the version information of printing device, need to judge whether auto-update then, auto-update is then downloaded the printing device upgrade data to local computer from the webserver of printing device manufacturer if desired, and computing machine sends to upgrade data the printing device upgrading routine that is attached thereto then;
The computing machine that connects printing device is connected by the server of internet with printing device equipment vendors, and both sides guarantee farthest to guarantee to receive the data of manufacturer no matter which kind of network environment is printing device be under by the http protocol communication like this.Owing to used the 80 the most general network ports, just can upgrade as long as realized the place that can carry out web access, how complicated no matter residing network environment has, no matter be present in which kind of fire wall inside.
(3) if printing device needs upgrading, then download up-to-date upgrade data from the vendor equipment server, the binary file of promptly up-to-date equipment firmware is to the RAM storer of printing device controller; Sent upgrade with the joining computing machine of printing device to printing device, printing device enters into the upgrading routine, accept to be buffered to the upgrade data on the computing machine then, upgrade data is a binary file, and these upgrade datas that come from printing device manufacturer will be printed equipment and receive on the RAM on the printing device controller;
(4) printing device starts the upgrading routine automatically, in the firmware binaries file programming the upgraded read only memory ROM in the printing device controller;
The ROM of the print control unit in printing device comprises three partial contents: 1) be positioned at the boot code area of zero-address, 2) zone that exists of the operating system of controller operation, 3) zone that exists of control program in the printing device controller.We are except guidance code will not be upgraded, other two operating systems and control program can be upgraded, bootcode upgrade is nonsensical, and guidance code is just inoperative because printing device is moved the back, does not influence the characteristic of printing device.It is the upgrading of printing device control program that upgrading is used maximum, because control program has determined the running status of printing device, and operating system nucleus is seldom upgraded.
The ROM of printing device controller is except several parts of appeal, in order to realize that faultless upgrading also needs the block size backup zone suitable with control program, can guarantee the minimum that influences that system received in the upgrading failure by suitable strategy like this, the ROM allocation of space as shown in Figure 4.
Read only memory ROM can be made of Flash flash memory, PROM or PPROM.In the present embodiment, the ROM in the printing device is made up of the Flash flash memory.To the programming of ROM, described in the background technology of front, dual mode is arranged, a kind of is by specific fever writes Flash to be programmed, programming is to cause the address date pin of Flash chip to present corresponding high-low level order by programmable device to finish to Flash.Another kind is that the program with programming ROM also is stored among the ROM, and ROM programming program is in service at ROM in the time of upgrading, directly ROM is upgraded.For Flash being programmed by specific fever writes, the Flash programming is if realize that auto-update just must save Flash programmable device hardware, but by allowing the ordinary procedure operation time simulate the high-low level sequence of the specific pin of Flash, so just realized the programming function of Flash in the present embodiment by the program on the equipment.The process of the programming of Flash generally is at first by wiping certain regional data, and then should the zone with Refresh Data to be written.
ROM programming function can break away from programmable device and realize, ROM programming program can be printed facility control program and call as the part of operating system nucleus.We also need to tackle in whole upgrade process if the processing during extreme cases such as outage.If fail in Flash programming process, then the data of the upgrade area among the Flash are invalid.So be divided into four bulks by us among the ROM, as shown in Figure 4.
In upgrading, three zones of Flash except guidance code are used in new datacycle, simultaneously the in store effective pointer that is writing down that zone of boot code area.
In the time of upgrading, the upgrading routine can be checked and verification after programming is finished new upgrade data programming to that idle zone, if confirm the programming success, upgraded the pointer in the guidance code.This moment, start back guidance code should be the program in the up-to-date zone again, as shown in Figure 5.
Because all being directed code copy, printing device control program and controller function system in RAM, moving.After powering up, guidance code is at first judged the pointer of valid function system and control program, then effective operating system and control program is copied to RAM, gives operating system operation power then.So this two blocks of data all is incoherent with the ROM address, realized guaranteeing to have finished preventing the upgrading of collapsing with less Flash space so recycle ROM.
Situation about the mistake appearance, the process of most critical is the programming of Flash, if mistake appears in programming, in the upgrading routine, can carry out verification and inspection to the content of programming after the upgrading, the content programming is correct if guarantee to upgrade, just begin the final step of upgrading: revise the pointer in the guidance code, we will guarantee that equally also mistake does not appear in the modification of pointer.Pointer adopts double copies, and each pointer will be enclosed its update date.When revising certain pointer, at first revise one of them, and then revise second backup.In the time of the system boot code reading pointer, whether the value that compare two is consistent, if inconsistent, then adopts that pointer early.Can guarantee like this to revise under the situation of pointer mistake, use original system.Effective operating system nucleus of pointed in the guidance code and printing device control program.When printing device powered up startup, guidance code will copy effective content among the RAM to according to the content of pointer, so jumps to RAM and moves effective program.
