Fig. 1 is a schematic view of an alternative image forming apparatus provided by the present invention. The start control method provided by the invention can be applied to the image forming apparatus shown in fig. 1, and the image forming apparatus shown in fig. 1 comprises a main control board card and a daughter board card. Wherein master control integrated circuit board is data control board, and the daughter board card includes: a scan control panel, a user interface UI control panel, an engine control panel, and a fax control panel.
It should be noted that: the number and types of daughter boards in fig. 1 are only an illustration, and daughter boards in the image forming apparatus may be any one or a combination of a plurality of daughter boards shown in fig. 1, and the present invention is not limited to the number and types of daughter boards shown in fig. 1.
In fig. 1, the data control board may transmit an instruction to each daughter card through the command interface, and respectively transmit image information with the scan control board and the engine control board through the image interface, and a method of data transmission between the data control board and each daughter card is similar to that of the prior art, and is not described herein again.
The following describes the start control method provided by the present invention in detail with reference to specific embodiments. These several specific embodiments may be combined with each other below, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart illustrating a first embodiment of a start control method according to the present invention. As shown in fig. 2, the start control method provided by the present invention includes:
s201, after the image forming device is powered on, the main control board card authenticates each sub-board card in the image forming device.
Wherein, the image forming apparatus is powered on by: the power switch of the image forming apparatus is turned on and the image forming apparatus is supplied with electric power.
Wherein, the sub-board card inside the image forming device includes: at least one of a scan control panel, a user interface UI control panel, an engine control panel, and a fax control panel. That is, the daughter board card inside the image forming apparatus may only have any one daughter board card or may include two or more daughter board cards according to the function or design requirement of the image forming apparatus itself.
Such as: the daughter card inside the image forming apparatus may include any one of the above control boards, for example, the daughter card inside the image forming apparatus includes only the scan control board; the daughter card inside the image forming apparatus includes only a user interface UI control panel; the daughter card inside the image forming apparatus includes only an engine control board; the daughter card inside the image forming apparatus includes only a facsimile control board.
The daughter card inside the image forming apparatus may include a combination of two or more of the above-described control boards, for example, the daughter card inside the image forming apparatus includes: a scan control panel, a User Interface (UI) control panel, an engine control panel and a fax control panel; the daughter card inside the image forming apparatus includes: a scan control panel, a user interface UI control panel and a fax control panel; the daughter card inside the image forming apparatus includes: a scan control panel and a user interface UI control panel.
Taking the example that the daughter card inside the image forming apparatus only includes the scan control board, after the image forming apparatus is powered on, the motherboard card authenticates the scan control board, and determines whether to execute the step S202 according to the authentication result. The authentication process of only one daughter card inside the image forming apparatus is similar to the above process, and the description of the present invention is omitted.
A daughter card inside an image forming apparatus includes: for example, the scan control board, the user interface UI control board, and the fax control board, after the main board card is powered on, the main board card sequentially authenticates the three daughter board cards in a certain order, and determines whether to execute the step S202 according to the authentication result of each daughter board card. The daughter card inside the image forming apparatus includes more than two authentication processes similar to the above processes, and the present invention is not described herein again.
In addition, it should be noted that: in the case where the image forming apparatus includes a plurality of daughter boards, each daughter board is not strictly required to be an independent circuit board, and may be set such that: the starting control method needs to be executed for the daughter card corresponding to each functional module as long as the control strategy for planning the daughter cards according to different functions is available, and verification can be executed once. For example, if an individual circuit board is provided with a daughter board card corresponding to the scanning control function module and a daughter board card corresponding to the user interface UI control function module, the main control board card may respectively verify the individual circuit board according to the scanning function module and the user interface UI control function module; it is also possible to perform the verification only once for this single circuit board; specifically, it is possible to confirm according to actual application, for example, when modules that may involve security problems on this separate circuit board are shared, for example, the scan control function and the UI control function share one memory, security authentication may be performed only once, and if even though one circuit board is shared on hardware, the involved security control modules are completely independent, separate authentication is required.
Optionally, before authenticating each daughter card, the main control board card may first detect whether each daughter card exists, and in the presence, perform an authentication process on the corresponding daughter card.
Specifically, after the image forming apparatus is powered on, the main control board starts to perform a detection process, assuming that the current detection is a scan control board, if the data control board detects that the scan control board exists, performing an authentication process on the scan control board, and after the authentication process is completed, starting to detect the next daughter board; if the data control board detects that the scanning control board does not exist, directly reporting errors, or after the detection and authentication processes of other daughter boards are finished, uniformly reporting errors with other daughter boards with abnormity.
One specific implementation of the data console detecting the presence of the scan console may be: the data control board sends a communication command to each daughter board card in sequence according to the communication mode (communication type, such as SPI, UART, IIC and the like) and the communication format (command format) of each daughter board card, and waits for the communication response of the daughter board card; if the daughter board card does not normally respond to the sent communication command within the preset time; judging that the daughter card is not installed or installed in place (namely, does not exist); if the communication command can be correctly responded within the preset time, the daughter card is considered to exist.
Optionally, each daughter board card stores corresponding daughter board card information, where the daughter board card information includes: the type of the daughter board card, the serial number of the daughter board card, the hardware version number of the daughter board card and the hardware version number of the daughter board card. The main control board card can authenticate the daughter board card according to the daughter board card information read from the daughter board card.
S202, if each daughter board card in the image forming device passes the authentication, the main control board card controls the image forming device to start: namely, if each daughter board card in the image forming device passes the authentication, the main control board card judges that the daughter board cards in the image forming device all meet the safety requirement, and subsequent operation processing can be executed; the "start-up" mentioned in this embodiment is a state in which each daughter card in the image forming apparatus can control the corresponding electromechanical actuator to enter a normal operating state.
Specifically, in S201, the main control board card authenticates the daughter boards, one of which is that all the daughter boards in the image forming apparatus are authenticated, and the other is that a daughter board in the image forming apparatus has an authentication failure; the main control board card controls the start of the image forming device only under the first authentication result, so that all the daughter boards are guaranteed to be the daughter boards meeting the safety requirements when a user uses the image forming device, and the leakage of user printing information is prevented.
According to the start control method provided by the embodiment, after the main control board card is powered on the image forming device, each daughter board card in the image forming device is authenticated, and the image forming device is controlled to start under the condition that all the daughter board cards in the image forming device pass the authentication, so that all the daughter board cards are the daughter board cards meeting the safety requirements, and the leakage of user printing information is prevented.
The following describes a process of authenticating the daughter card by the main control board card according to the daughter card information in the above embodiments with reference to a specific embodiment.
Fig. 3 is a flowchart illustrating a second embodiment of a start control method according to the present invention. As shown in fig. 3, in the start-up control method provided in this embodiment, S301 to S304 are processes of detecting and authenticating any daughter board card in the image forming apparatus, and for convenience of description, the current daughter board card is used to represent any daughter board card, where it is to be noted that when there are more than two daughter board cards in the image forming apparatus, all daughter board cards in the image forming apparatus can be detected and authenticated in the manner of S301 to S304. Specifically, the method comprises the following steps:
s301, after the image forming device is powered on, the main control board card detects whether the current daughter board card exists.
If yes, executing S302;
if not, directly reporting errors, or after the detection and authentication process of other daughter cards is finished, uniformly reporting errors with other daughter cards with abnormity.
And S302, the main control board card reads the daughter board card information from the current daughter board card.
And S303, the main control board card judges whether the current daughter board card is legal or not according to the daughter board card information.
The implementation manner of judging whether the current daughter board card is legal by the master control board card is as follows:
the main control board card compares the daughter board card serial number of the current daughter board card with the serial number stored in the illegal daughter board card information base, and if the daughter board card serial number of the current daughter board card does not exist in the illegal daughter board card information base, the current daughter board card is judged to be legal; and if the daughter board card serial number of the current daughter board card exists in the illegal daughter board card information base, judging that the current daughter board card is illegal.
The serial number stored in the illegal daughter card information base is the serial number of the daughter card which is not matched with the image forming device or has information leakage risk.
If the main control board judges that the current daughter board is legal, the step S304 is further executed.
If the main control board card judges that the current daughter board card is illegal, the authentication process of the current daughter board card is ended, and an error is directly reported or is uniformly reported with other daughter boards with abnormity after the detection and authentication processes of other daughter boards are finished.
And S304, the main control board card carries out digital verification on the current daughter board card according to the daughter board card information.
The implementation mode of the main control board card for performing digital verification on the current daughter board card comprises the following steps:
the main control board card searches whether a digital signature value corresponding to the category of the current sub-board card exists in an authentication sub-board card information base or not according to the category of the current sub-board card;
if yes, verifying the current daughter card information according to the digital signature value;
the method for verifying the current daughter board card information according to the digital signature value can be realized by the following steps:
the main control board card carries out digital signature on the current sub-board card information by adopting a preset signature algorithm to obtain a current signature value, the current signature value is compared with a digital signature value retrieved from an authentication sub-board card information base, if the comparison is successful, the current sub-board card is indicated to be an original sub-board card, the verification of the current sub-board card is confirmed to be passed, and therefore the authentication of the current sub-board card is confirmed to be passed; if the comparison is not successful, the current daughter board card is not the original daughter board card, and at this time, the main control board card can control to output first prompt information, where the first prompt information is used to prompt a user to select a processing mode, the user can select to continue using the current daughter board card according to the first prompt information, or abandon the use of the current daughter board card, and the main control board card can determine whether the current daughter board card passes the authentication according to the processing mode selected by the user.
If the digital signature value corresponding to the type of the current daughter board card does not exist in the authentication daughter board card information base, the current daughter board card is indicated to be a new installed daughter board card, digital signature is carried out on daughter board card information of the current daughter board card to obtain a digital signature value, the digital signature value is stored in the authentication daughter board card information base, and the current daughter board card is regarded as passing authentication.
The following describes the processes of S301 to S304 by taking the authentication of the UI control board (current daughter board) by the data control board (main control board) in fig. 1 as an example:
the data control panel detects that the UI control panel exists the back, reads the daughter board card information of UI control panel, and this daughter board card information includes: the type of the UI control panel, the daughter board card serial number of the UI control panel, the daughter board card hardware version number of the UI control panel and the daughter board card hardware version number of the UI control panel. The data control panel compares the daughter board card serial number of the UI control panel with the serial number stored in the illegal daughter board card information base, if the daughter board card serial number of the UI control panel does not exist in the illegal daughter board card information base, the UI control panel is considered to be legal, the data control panel further conducts digital verification on the current daughter board card according to the daughter board card information, if the verification is successful, the UI control panel is considered to be in original configuration, and therefore the UI control panel is determined to pass the authentication.
S305, if each daughter board card in the image forming device passes the authentication, the main control board card controls the image forming device to start.
Specifically, all daughter cards in the image forming apparatus are authenticated through steps S301 to S304, and the image forming apparatus is controlled to be started up when all daughter cards are authenticated.
The start control method provided by this embodiment describes an implementation manner of authenticating the daughter board card according to the information of the daughter board card, and after the authentication process, all the daughter board cards in the image forming apparatus are legal and original cards, so that it is ensured that all the daughter board cards are daughter boards meeting the safety requirements, and leakage of user printing information is prevented.
In the above embodiment S304, when the comparison result indicates that the daughter card is not the original daughter card, the first prompt information is controlled to be output to prompt the user to select the processing mode, and the administrator can be prompted to perform corresponding authentication selection. Fig. 4 is a schematic flowchart of a third embodiment of a start-up control method provided in the present invention, where the start-up control method provided in this embodiment includes:
the following S401 to S407 are authentication processes taking the current daughter board card as an example, and it needs to be described that: all daughter cards within the image forming apparatus can be authenticated by this process.
S401, after the image forming device is powered on, the main control board card detects whether the current daughter board card exists.
If so, go to step S402.
S402, the main control board card reads the daughter board card information from the current daughter board card.
And S403, the main control board card judges whether the current daughter board card is legal or not according to the information of the daughter board card.
If yes, go to step S404.
S404, the main control board card searches whether a digital signature value corresponding to the category of the current daughter board card exists in the authentication daughter board card information base according to the category of the current daughter board card.
If so, S405 is executed.
S405, verifying the current daughter board card information according to the digital signature value.
If the verification is not successful, step S406-S407 is executed, or step S406' -S407' is executed, or step S406-S407 ' is executed first and then step S406' -S407' is executed, as shown in FIG. 4 by executing step S406-S407 first and then step S406' -S407 '.
S406, the main control board card controls and outputs first prompt information, and the first prompt information is used for prompting a user to select a processing mode.
And S407, the main control board card determines whether the current daughter board card passes the authentication according to the processing mode selected by the user.
Specifically, the first prompt information can be displayed to the user through the panel of the image forming device, voice broadcasting, light flashing and other modes, and after the user receives the first prompt information, the user can select to continue using the current daughter board card through the panel or select to abandon using the current daughter board card.
