  Hereinafter, an embodiment of a power saving system and a power saving program according to the present invention will be described in detail with reference to the accompanying drawings.

  In the following embodiments, a printer is shown as an example of an information processing apparatus. However, the present invention is not limited to a printer, and any network node having a power saving function may be used.

  FIG. 1 is a network configuration diagram and a device configuration diagram configured by applying a power saving system and a power saving program according to the present invention.

  In FIG. 1, a printer 100 having a plurality of communication interface controllers, and a host PC (10, 20), which is an information processing requesting device that makes a processing request to the printer 100, is a LAN (Local Area Network) cable, a dedicated line, 1 shows a configuration for saving power consumption of a communication interface controller included in the printer 100. FIG.

  The communication interface controller is also called a communication control device, and is an interface that controls communication between network nodes.

  In the following description, an example in which Ethernet (registered trademark) communication is performed using a LAN cable such as a UTP (Unshielded Twist Pair) cable or a fiber cable is shown, and the printer 100 or the host PC (10, 20) described above is shown. In addition to the above, although not shown, the network configuration includes various communication processing servers such as a DNS (Domain Name Service) server and a DHCP (Dynamic Host Configuration Protocol) server.

  First, the host PC 10 and the host PC 20 are information processing requesting devices that make processing requests to the printer 100, and driver software (hereinafter “driver”) corresponding to the printer 100 is installed. In the host PC (10, 20), application data is created using various applications such as document creation software and spreadsheet software, and print data is generated by an installed driver.

  Further, each host PC (10, 20) is equipped with a port monitor, and the port monitor manages communication of data transmitted over the network. In this port monitor, UDP (User Datagram Protocol) is used as the protocol of the transport layer, which is the fourth layer of the OSI basic reference model, and print data in a communication format to be transferred to the printer 100 is created.

  Further, the created print data in the communication format is divided into transfer units such as an MTU (Maximum Transfer Unit) that transmits over the communication line 30. Communication quality is guaranteed by assigning a sequence number, which is a data-specific number indicating the order, to the data portion of the divided print data.

  Next, the printer 100 includes a communication interface controller A (110), a communication interface controller B (120), a communication general-purpose memory 130, and an image forming unit 140, which are received from the host PC via any communication interface controller. Print data is printed.

  The image forming unit 140 performs image processing on the print data received via the communication interface controller, and prints out the print data subjected to the image processing. Further, the image forming unit 140 is equipped with a power saving function that is in a power saving state in which power consumption is reduced when printing output is not performed for a certain period of time. A (110) and communication interface controller B (120) are notified of this.

  The communication interface controller (110, 120) is a communication controller that relays print data received from the host PC (10, 20) to the image forming unit 140, and between the communication interface controllers of each other when the printer 100 is turned on. Exchange media identification numbers such as MAC addresses. By exchanging the medium identification number, each communication interface controller can identify the other communication interface controller.

  Similar to the image forming unit 140, these communication interface controllers (110, 120) are equipped with a power saving function, and operate by receiving a power saving state from the image forming unit 140. At this time, not all the communication interface controllers are put into the power saving state by the power saving function, but at least one communication interface controller continues the activated state.

  The communication interface controller that shifts to the power saving state by the power saving function notifies the communication interface controller in the normally activated state that it is in the power saving state, and allows the data addressed to itself to be processed by the communication interface controller in the always activated state. .

  In this communication interface controller (110, 120), processing is performed as follows for each layer indicated by the OSI basic reference model.

  First, in the PHY / MAC layer (111) constituting the first layer and the second layer of the OSI basic reference model, data transfer is performed by performing timing control, flow control, and the like in order to perform normal data transfer. Next, in the IP layer (112) constituting the third layer, mutual data communication such as route selection and relay processing is performed using the data transfer function provided by the lower layer.

  Further, the UDP layer (113) is configured as the fourth layer, and supports normal data communication in data communication. In the processing in the UDP layer (113), it is possible to assemble print data for image processing from each received communication data by referring to the sequence number included in the UDP data portion of the received communication data.

  Then, in the application layer (114) in which the fifth and higher layers are gathered, for example, a print instruction based on print conditions is given to the image forming unit 140 by LPR (Line PRinter daemon protocol) that performs a print service.

  When a communication interface controller processed according to such an OSI basic reference model is in a power saving state, data destined for the communication interface controller is stored in the communication general-purpose memory 130.

  The communication general-purpose memory 130 is a storage device configured by a RAM (Random Access Memory) or the like, and communication data addressed to a communication interface controller that is in a power saving state by a power saving function is in a communication interface in another active state. It is a storage device that stores temporarily upon reception by the controller.

  When the storage capacity of the communication general purpose memory 130 reaches a predetermined amount, the communication interface controller that is always in the activated state detects this. The detected communication interface controller makes a start request to the communication interface controller that is the destination of the host PC in the power saving state, together with flow control that temporarily requests the transfer source host PC to temporarily stop data transfer.

  For example, when the communication interface controller A is always activated and the communication interface controller B is shifted to the power saving state by the power saving function, when the storage capacity of the communication general-purpose memory 130 reaches a certain amount, the communication interface controller A performs communication. An activation request is made to the interface controller B, and the communication interface controller B performs an activation process to enter an activation state.

  The communication interface controller B acquires communication data addressed to itself from the communication general-purpose memory 130 and performs processing according to the OSI basic reference model as described above.

  At this time, data is also received from the host PC in which data transfer is suspended by flow control.

  The communication interface controller that has received the communication data refers to the sequence number assigned to the data portion of the UDP data of the received communication data, and performs a synthesis process for assembling each communication data into one piece of information. When the data is successfully assembled by the combining process, a data reception completion notice is transmitted to the transmission source host PC.

  Then, the image processing is performed by transferring the information combined by the combining processing to the image forming unit 140.

  FIG. 2 is a sequence diagram showing process transitions in the configuration of FIG.

  The sequence shown in FIG. 2 shows a process transition performed between the printers with two communication interface controllers connected to the host PC. The communication interface controller indicates data communication using an internal bus, and the communication interface controller and the host PC indicate data communication via a communication line.

  The two communication interface controllers are indicated as communication interface controller A and communication interface controller B, respectively.

  When the printer is turned on, the communication interface controller A and the communication interface controller B exchange the MAC address, which is medium identification information, in order to confirm the mutual connection state (201).

  If the communication interface controller B is not used for a certain period of time after the exchange of the MAC address, a power saving process is performed (202), and the communication interface controller A that is always in operation detects that it has shifted to the power saving state ( 203).

  Thereafter, a print request is made by the host PC (204), and when communication data destined for the communication interface controller B in the power saving state is sent, medium identification information such as a MAC address is exchanged to enter the power saving state. The communication interface controller A, which has recognized it, receives the communication data (205) and stores it in the communication general-purpose memory (206).

  When storing in the communication general-purpose memory, if the storage capacity stored in the communication general-purpose memory exceeds a predetermined amount, the communication interface controller A detects this (207) and activates the communication interface controller B. A request is made (208).

  Upon receiving the activation request, the communication interface controller B shifts to an activated state by performing an activation process (209). In the activated state, the communication data addressed to the communication interface controller B stored in the communication general-purpose memory is acquired (210, 211).

  Further, in the host PC, when the communication general-purpose memory becomes a certain amount during the transfer of the communication data and the data transfer is temporarily stopped and the communication interface controller B is activated, the data transfer is resumed. At this time, since the communication data to be transferred is data destined for the communication interface controller B, it is directly received by the communication interface controller B (212).

  When all the data is received, the communication interface controller B performs a composition process for assembling data with reference to the sequence number assigned to the data part of the UDP protocol indicated by the received communication data (213).

  When the data is normally received, a data reception completion notification is transmitted to the host PC that is the transfer source (214), and the data assembled by the composition process is transferred to the image forming unit to perform the power saving process ( 215).

  Incidentally, when data reception is not normally performed due to packet duplication or loss, a data retransmission request command is transmitted to the port monitor of the host PC to retransmit the data.

  By this power saving process, the communication interface controller B is again in the power saving state.

  FIG. 3 is a diagram illustrating an example of UDP data.

  FIG. 3 shows a data format in the case where UDP is used for the fourth layer of the OSI basic reference model, and includes a UDP header part 300 and a UDP data part 310.

  The UDP header section 300 is composed of a destination port number 301, a transmission source port number 302, a data length 303, and a checksum 304, and the UDP data section 310 is composed of a sequence number 311 and print data 312.

  A sequence number 311 is provided in the UDP data section 310, and this sequence number 311 is given when the data is divided by the host PC, and indicates the configuration order of the print data before the division.

  That is, the communication interface controller of the printer that has received the UDP data assembles the communication data based on this sequence number.

  FIG. 4 is a diagram showing a processing state of UDP data in the OSI basic reference model.

  FIG. 4 shows a configuration in which a processing request source host PC and a printer are connected, and a sequence number is assigned to the data portion of UDP data created by the UDP protocol in the port monitor of the host PC, and transferred to the printer via a communication line. Has been shown to do.

  In the printer that has received the UDP data, the communication data is processed for each layer, the UDP layer in the fourth layer is processed for the UDP header, and then the application layer indicating the fifth layer or higher is transferred from the data portion of the UDP data. The print data is assembled from each communication data with reference to the sequence number.

  That is, the print data can be assembled without changing the data transmitted on the Ethernet (registered trademark).

  In the first embodiment, the host PC (10, 20) and the printer 100 are connected via the communication line. However, in the second embodiment, the host PC (10, 20) and the printer 100 are connected to each other. 1 shows a wireless network that performs data communication by wireless communication.

  Since the second embodiment is similar to the processing and configuration shown in the first embodiment, different points will be mainly described.

  FIG. 5 is a network configuration diagram and a device configuration diagram configured by applying the power saving system and the power saving program according to the present invention.

  FIG. 5 includes a printer 100 having a plurality of wireless communication interface controllers (510, 520), a wireless host PC (50, 60), and a wireless access point (hereinafter referred to as “wireless AP”) (70, 71). A printing system is shown, and print data requested for printing from a wireless host PC (50, 60) is transferred to the printer 100 via a wireless AP (70, 71) having a bridge function for relaying wireless communication data. Is done.

  The wireless AP (70, 71) is provided with a buffer for temporarily storing data, and temporarily stores data relayed from the wireless host PC (50, 60) to the printer 100.

  As in the first embodiment, UDP is used as a communication protocol for data to be relayed, and a sequence number that is a data unique number is assigned to the data portion of UDP data.

  Detailed process transitions in the configuration shown in FIG. 5 are shown in FIGS.

  FIG. 6 is a sequence diagram showing process transitions in the configuration of FIG.

  The two wireless communication interface controllers installed in the printing apparatus are respectively referred to as a wireless communication interface controller C and a wireless communication interface controller D, and the wireless communication interface controller C is always activated.

  In the sequence shown in FIG. 6, the wireless communication interface controller C is in a state where a logical communication path is established with the wireless AP (70), and the wireless communication interface controller D is in a state where a logical communication path is established with the wireless AP (71). It is in.

  First, when the printer is turned on, the MAC address, which is medium identification information, is exchanged between the wireless communication interface controller C and the wireless communication interface controller D in order to confirm the mutual connection state (601).

  Further, the wireless communication setting information is also exchanged (602). The wireless communication setting information is setting information for each wireless communication interface to realize wireless communication. For example, the ESS-ID and the communication speed that enable the wireless communication interface to recognize the wireless AP (70, 71). Indicates the modulation method.

  When these pieces of information are exchanged between the mutual wireless communication interface controllers and the state where the communication interface controller B is not used continues for a certain period of time, the wireless communication interface controller D enters the power saving state by performing the power saving process of the printer. 603). The wireless communication interface controller C confirms the power saving state of the wireless communication interface controller D (604).

  In this state, the wireless host PC makes a processing request (605), and when data is transferred (606), a logical communication path is established between the wireless AP and the wireless communication interface controller. Details of the logical communication path establishment processing are shown in the sequence of FIG.

  The logical communication path establishment process is a process in which the wireless communication interface controller C establishes a logical communication path with the wireless AP (71) using the wireless communication setting information of the wireless communication interface controller D that has entered the power saving state.

  When the logical communication path establishment process as shown in FIG. 7 is performed, data transfer is received from the wireless AP (608), and the wireless communication interface controller C stores the data in the communication general-purpose memory (609). When the storage capacity stored in the communication general-purpose memory exceeds a predetermined amount during storage in the communication general-purpose memory, the communication interface controller C detects this (610) and activates the communication interface controller D. A request is made (611).

  Upon receiving the activation request, the communication interface controller D shifts to an activated state by performing an activation process (612). In the activated state, the data addressed to the communication interface controller D stored in the communication general purpose memory is acquired (613, 614).

  Further, in the host PC, the data transfer is resumed when the communication interface controller D is activated when the communication general purpose memory becomes a certain amount during the transfer of the communication data and the data transfer is temporarily stopped ( 606). At this time, since the data to be transferred is data destined for the communication interface controller D, the data is directly received by the communication interface controller D (615).

  When all data is received, the communication interface controller B performs a composition process for assembling data with reference to the sequence number assigned to the data part of the UDP protocol indicated by the received communication data (616).

  If the data is normally received, a data reception completion notification is transmitted to the wireless host PC that is the transfer source (617), and the data assembled by the synthesis process is transferred to the image forming unit to perform the power saving process. (618).

  Incidentally, when data reception is not normally performed due to packet duplication or loss, a data retransmission request command is transmitted to the port monitor of the host PC to retransmit the data.

  By this power saving process, the communication interface controller D is again in the power saving state.

  FIG. 7 is a sequence diagram showing a detailed process transition of the process for establishing the logical communication path shown in FIG.

  FIG. 7 shows a state in which the wireless communication interface controller D is in a power saving state and a logical communication path is established between the wireless communication interface controller D and the wireless AP 2, and the logical communication between the wireless communication interface controller C and the wireless AP 1 When the wireless AP 2 receives data from the wireless host PC, it is stored in the buffer (702).

  The wireless AP 2 periodically issues a beacon frame to the communication interface controllers of all the wireless communication nodes (703), and the wireless communication interface controller C detects the TIM information (Traffic Indication Message) included in the beacon frame. As a result, the wireless AP 2 recognizes that the data for the wireless communication interface controller D is stored (704). This TIM information is a message for instructing wireless communication.

  Then, the wireless communication interface controller C, which has recognized that data for the wireless communication interface controller D is stored in the wireless AP 2, establishes a logical communication path with the wireless AP 2 based on the previously exchanged MAC address and wireless communication setting information. (706).

  In a state where the logical communication path is established, the wireless communication interface controller C performs a temporary power saving state notification to the wireless AP 1 from which the logical communication path is originally established (707). The wireless AP 1 that has received the temporary power saving state notification recognizes that the wireless communication interface controller C has entered the wireless state (708).

  Then, the wireless communication interface controller C transmits a PS-Poll signal to the wireless AP 2 storing the data received from the wireless host PC, thereby enabling reception of the data.

  With the sequences shown in FIGS. 6 and 7, the power saving process of the communication interface controller can be performed even by wireless communication.

  The present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within the scope not changing the gist thereof.

  In the present invention, the program is executed from a recording medium (CD-ROM, DVD-ROM, etc.) that stores the program for causing the power saving system having a communication function to execute the above-described operation or to configure the above-described means. It is also possible to configure an information management system that executes the above-described processing by installing it on a computer and executing it. A computer constituting the power saving system is connected to a central processor unit (CPU), a read only memory (ROM), a random access memory (RAM), and a hard disk via a system bus. The CPU performs processing using the RAM as a work area according to a program stored in the ROM or the hard disk.

  The medium for supplying the program may be a communication medium (a medium for temporarily or fluidly holding the program such as a communication line or a communication system). For example, the program may be posted on an electronic bulletin board (BBS: Bulletin Board Service) of a communication network and distributed via a communication line.
