Description

  The present invention relates to an image processing apparatus, an image forming apparatus, an abnormality management processing method, and an abnormality management processing program, and more particularly to an image processing apparatus, an image forming apparatus, and an abnormality management that appropriately perform abnormality management such as failure of a plurality of modules. The present invention relates to a processing method and an abnormality management processing program.

  Various image processing apparatuses such as a copying apparatus, a facsimile apparatus, a printer apparatus, a composite apparatus, and a scanner apparatus tend to be highly functional and diversified. In particular, the functions are a copy function, a facsimile function, a printer function, and a scanner function. In a multi-function device having a plurality of functions such as a plurality of units (modules) each equipped with a controller including a CPU (Central Processing Unit) in one multi-function device, it is necessary to control various functions. We are getting ready.

  In such an image processing apparatus equipped with a plurality of modules, each unit is connected by an interface such as USB (Universal Serial Bus), and an abnormality occurs in some modules before this interface is established. Then, it is impossible to know what abnormality has occurred in which module.

  For example, if the operation unit and the main controller are connected via USB, the operation unit is a USB device, and the main controller is a USB host, the operation unit will not establish communication if an abnormality that does not start the main controller occurs. Only the fact can be grasped, and error information that communication is not established can only be displayed on the display of the operation unit. As a result, the cause of the system not starting, that is, the error content cannot be displayed.

  Conventionally, a synchronous serial bus having a data signal line and a synchronization signal line, a shift clock is sent to the synchronization signal line, and an address for specifying a slave on the data signal line and master side data are sent to the shift clock. And a plurality of slaves connected to the synchronous serial bus, each of which shifts the slave side data in response to an address and master side data identifying itself from the master. Synchronously with the clock, serially send to each slave signal line connected to each of the slaves, slave side data signal lines connected to the master, and address data sent by the master to the synchronous serial bus Read and generate a signal specifying the slave specified by the address data Slave-side data selection for sending slave-side data sent serially in synchronization with the shift clock of the slave signal line connected to the slave specified by the master-side data monitoring means and the specified signal to the slave-side data signal line A serial data communication device including a slave data control device including means has been proposed (see Patent Document 1).

  In other words, this conventional technique receives a reply from the slave side data signal line from all of the slaves in response to transmission from the master, so that the master does not switch the signal line for reading the master reply. The number of master side signal lines (number of input ports) is reduced to reduce the load of reply reading and to increase the processing speed of data transmission / reception with respect to all of the plurality of slaves.

  However, in the prior art described in the above publication, all of the plurality of slaves are only returned from the slave side data signal line in response to transmission from the master. Of these, when an abnormality occurred in a part, it was necessary to improve in order to make it clear from the outside what kind of abnormality occurred in which module. For example, in the above prior art, when the main controller is a master and the controller such as a plotter unit or an operation unit which is another module is a slave, an error occurs before communication between the main controller and the operation unit is established. When this occurs, the controller of the operation unit can only display error information that communication is not established on the display unit of the operation unit on the display of the operation unit. The problem of not being able to display cannot be solved.

  Accordingly, an object of the present invention is to provide notification of abnormality information in a plurality of existing modules inexpensively and accurately.

  In order to achieve the above object, the image processing apparatus according to claim 1 communicates between a plurality of modules each realizing a predetermined function and another module necessary for realizing each function among the modules. And a communication means that is mounted in each of the modules and that acquires abnormality information in each module and communicates with each other.

  According to the present invention, abnormality information in a plurality of modules can be notified inexpensively and accurately.

And I2C3a displays the error information received from I2C2a of the main controller 2 on the display for notification.

  The engine unit 4 is a scanner unit that reads an image of a document by performing main scanning and sub-scanning on the document, a printing unit that forms an image on a sheet by a predetermined image forming process (for example, an electrophotographic process) based on image data, and the like. The image data of the document read by the scanner unit is sent to the main controller 2 via the PCIe bus 6 or received from the main controller 2 via the PCIe bus 6. The printing unit records and outputs an image on a sheet based on the image data.

  The power saving unit 5 monitors the operation of the main controller 2 via the PCI bus 7, and when the standby state has passed a predetermined waiting time, the power saving mode stops or reduces the supply of power to the main units. And detecting various return factors, for example, detection of a document set on the scanner unit of the engine unit 4, opening operation of the main body housing of the multifunction device 1, key operation of the operation unit 3, etc. A return process from the power saving mode to the standby mode in which the normal operation is possible is performed.

  The I2C2a of the main controller 2, the I2C3a of the operation unit 3, the I2C4a of the engine unit 4, and the I2C5a of the power saving unit 5 are respectively connected to the I2C bus 9, as shown in FIG. It is connected to the pull-up power supply voltage Vdd via a pull-up resistor R (usually about 1 KΩ). Each I2C2a, 3a, 4a, 5a uses the same device, but as a built-in program, the I2C2a of the main controller 2 and the I2C3a of the operation unit 3 can operate as a master and a slave. Are stored, and only the program that can operate as a slave is stored in the I2C4a of the engine unit 4 and the I2C5a of the power saving unit 5. That is, in the composite apparatus 1, the I2C2a of the main controller 2 and the I2C3a of the operation unit 3 are selectively selected from the I2C2a of the main controller 2, the I2C3a of the operation unit 3, the I2C4a of the engine unit 4, and the I2C5a of the power saving unit 5. A multi-master I2C system that can be a master has been constructed.

The SCL terminal and the SDA terminal are provided. The communication protocol of I2C is generally shown as in FIG. In the I2C communication protocol, the serial clock (SCL) is a signal line for synchronization, and is usually one direction from master to slave. In the I2C communication protocol, the communication is performed by changing the serial data (SDA) while the SCL is Low, and holding the SCL at High. Further, in the I2C communication protocol, serial data (SDA) is a signal line used for data transfer in synchronization with SCL and may be transmitted from either a master or a slave. In the I2C communication protocol, an ACK (ACKnowledgement) command is also transmitted through the SDA, and the transfer direction changes at any time during communication depending on the R / W before the ACK command. In the I2C communication protocol, data starts from a start condition S, changes in data are performed when SCL is Low, actual data transmission / reception continues, and ends in a stop condition.

  In addition, the multifunction device 1 has an address “001” for the I2C2a of the main controller 2, an address “002” for the I2C3a of the operation unit 3, and an address “003” for the I2C4a of the engine unit 4. However, the address “004” is assigned to the I2C 5 a of the power saving unit 5.

That is, the frame is composed of [communication source address] [command] [data length] [data depending on the command]. As the command, [Ready inquiry] is [0x01] and [Ready notification] is [0x02]. ], [Error notification] is [0x03], and [Normal operation transition notification] is [0x04]. When the data length is [0], the [data length] is [0], and there is no subsequent [command-dependent data].

  Then, as the abnormality management processing program of the present invention, the multifunction device 1 has both the master and slave programs mounted on the I2C2a of the main controller 2 and the I2C3a of the operation unit 3, and the I2C4a of the engine unit 4 which is another unit.

That is, the composite apparatus 1 includes a ROM, an EEPROM (Electrically Erasable and Programmable Read Only Memory), an EPROM, a flash memory, a flexible disk, a CD-ROM (Compact Disc Read Only Memory), a CD-RW (Compact Disc Rewritable), a DVD ( An abnormality management processing program for executing the abnormality management processing method of the present invention recorded on a computer-readable recording medium such as a digital versatile disk (SD), a secure digital (SD) card, or a magneto-optical disc (MO) is read. Both the master and slave programs are installed in the I2C2a of the main controller 2 and the I2C3a of the operation unit 3, and the programs as slaves are installed in the I2C4a of the engine unit 4 and the I2C5a of the power saving unit 5 which are other units. In response to the error information of each unit 2 to 5, It is constructed as an image processing apparatus that executes the abnormality management processing method of the present invention by executing the master serial communication by I2C2a of the main controller 2, I2C3a of the operation unit 3, I2C4a of the engine unit 4, and I2C5a of the power saving unit 5. ing. This abnormality management processing program is a computer-executable program written in a legacy programming language such as assembler, C, C ++, C #, Java (registered trademark) or an object-oriented programming language, and is stored in the recording medium. And can be distributed.

  Next, the operation of this embodiment will be described. The composite device 1 according to the present embodiment notifies the abnormality information in the main controller 2, the operation unit 3, the engine unit 4, and the power saving unit 5, which are a plurality of modules, at low cost and accurately.

  That is, when the power source is turned on or when the power supply is turned on and returned from the power saving mode, the I2C 3a of the operation unit 3 is the master, the main controller 2, which is another module, the engine unit 4 and the I2C 2a of the power saving unit 5, 4a and 5a become slaves, and I2C3a of the operation unit 3 as a master is abnormal based on a response from the other I2C2a, 4a, and 5a to a Ready inquiry by a polling operation with the other I2C2a, 4a, and 5a. Determination is performed, and the determination result is displayed on the display of the operation unit 3.

  As shown in FIG. 3, the I2C 3 a of the operation unit 3 becomes the master by sending “L” SDA to the serial data line 9 b of the I2C signal line 9 before the I2C 2 a of the main controller 2. By using I2C2a, 4a, 5a as slaves and confirming responses from the other I2C2a, 4a, 5a, the main controller 2, engine unit 4 and power saving unit provided with the other I2C2a, 4a, 5a Detect and manage the presence or absence of 5 abnormalities.

  When the I2C 3a of the operation unit 3 becomes a master, as shown in FIG. 5, I2C 2a, 4a of the main controller 2, the engine unit 4 and the power saving unit 5 which are modules to be subjected to error management of the composite apparatus 1. 5a and a target module list set as a predetermined timeout time is initialized (step S101). This target module list is set in advance in the I2C3a register or the like.

  Next, the I2C3a updates the timeout time of the target module list (step S102), completes the abnormality management processing for all the target modules, and checks whether there are no target modules as abnormality management targets (step S103). ).

  When the target module exists in step S103 (NO in step S103), the I2C 3a checks whether the remaining time of the time-out time in the target module list has expired (step S104) and has expired. If not (NO in step S104), it is checked whether all target modules have been processed (step S105).

  When the processing has not been completed for all target modules in step S105 (NO in step S105), the I2C3a performs the polling operation on the target modules with the I2C3a of the operation unit 3 serving as a master. A reception operation is performed as a master (step S106), and it is checked whether the reception is successful (step S107).

  If the reception is successful in step S107, the I2C 3a removes the successful target module from the target module list (step S108), performs a slave operation for 50 ms, and receives an error notification or the like from the target module (step S109). ). Even when reception fails in step S107, the I2C 3a performs a slave operation for 50 ms and receives an error notification or the like from the target module (step S109).

  That is, the I2C 3a of the operation unit 3 performs error processing when an error processing command is sent from another module in the master operation in the abnormality management processing at the time of startup, as shown in FIG. A command is received during slave operation and an ACK command is sent to the module. Then, the I2C2a, 4a, and 5a of the module in which the error has occurred retry the error transmission process until the ACK command is transmitted from the I2C3a of the operation unit 3, and the ACK command is transmitted from the I2C3a of the operation unit 3. Then, the error content is transmitted according to the I2C communication method.

  That is, the I2C 3a of the operation unit 3 operates as a master and performs abnormality management of the main controller 2, the engine unit 4, and the power saving unit 5 that are the other modules 2, 4, and 5. Therefore, error notifications from the I2Cs 2a, 4a, and 5a of the other modules 2, 4, and 5 can be received during the slave operation.

  When the slave operation for 50 ms is performed, the I2C3a returns to step S104, and performs the same processing as described above from checking whether the remaining time has expired as described above.

  When the processing is completed for all target modules in step S105 (YES in step S104), the I2C 3a returns to step S102 to update the time-out time of the target module list (step S102). The same processing as described above is performed from the check of whether it has been lost (steps S102 to S109).

  If there is a target module whose remaining time has expired in step S104, the I2C 3a treats the target module as a non-response and processes it as a time-out error. For example, the operation unit displays a message indicating that a time-out error has occurred. 3 is performed, and the abnormality management process is terminated (step S110).

  If there is no target module in step S103 (YES in step S103), it is determined that all abnormality management processing has been completed, and the slave controller is shifted to a slave operation in response to a request from the I2C2a of the main controller 2, and abnormality management processing is performed. Is finished (step S111).

  Then, the main controller 2 sends a [Normal Operation Transition Notification] command indicating that the I2C 2a shifts to the normal operation by the master operation, as shown in FIG. The data is transmitted to I2C3a, I2C4a of the engine unit 4, and I2C5a of the power saving unit 5. Specifically, when the main controller 2 is successfully activated normally, the I2C 2a operates as a master, transmits a normal operation transition notification, an error processing command to the modules 3 to 5, and the other modules 3 to 5 When this error processing command is received during the slave operation, an ACK command is transmitted to the main controller 2 to the I2C 2a. The main controller 2 retries sending an error processing command until an ACK command is sent.

  When the main controller 2 receives the ACK command, the I2C 2a of the main controller 2 transmits an error content, that is, notifies the normal operation transition, and notifies the I2C 2a of the main controller to perform the subsequent error notification. The I2C 2a of the main controller 2 issues this normal operation transition notification for all the other modules 3-5.

  Then, when the operation is shifted to the normal operation, as shown in FIG. 8, the master moves from I2C3a of the operation unit 3 to I2C2a of the main controller 2, and I2C2a performs the same abnormality management processing as the abnormality management processing shown in FIG. Execute.

  That is, when the I2C 2a of the main controller 2 enters normal operation, communication on the high-speed bus has already been established, and error notification may be performed using this high-speed communication bus. Depending on the error condition of the high-speed bus, it may be necessary to perform error notification via I2C.

  Therefore, in the composite apparatus 1 of this embodiment, as shown in FIG. 8, the error notification during the normal operation is received by the I2C 2a of the main controller 2 as the master, and the error notification is received during the slave operation of the master. That is, the main controller 2 performs an abnormality determination based on a response to the Ready inquiry by the polling operation, with the I2C 2a as a master, and displays the determination result on the display of the operation unit 3. At this time, during the slave operation of I2C2a of the main controller 2, the I2C3a to 5a of the module in which the error has occurred sends an error to the I2C2a of the main controller 2 by the master operation, and an ACK command is sent from the I2C2a of the main controller Retry until returns. When the ACK command returns from the I2C2a of the main controller 2, the I2C3a to 5a of the other modules 3 to 5 transmit error contents to the I2C2a.

  As described above, the composite apparatus 1 according to the present embodiment includes a plurality of modules 2 to 5 each realizing a predetermined function, and other modules 2 to 5 necessary for realizing each function among the modules 2 to 5. I2C (abnormal communication means) 2a, which are mounted on buses (communication means) 6 to 8 and modules 2 to 5 and communicate with each other by acquiring abnormality information in the modules 2 to 5, respectively. 5a.
