Description

  The present invention relates to a communication control processing apparatus and program that can stop the retransmission of an announcement from a device that has received the announcement in a system that announces a status change of the device by broadcast communication.

  Conventionally, in a system connected by a network, the controller cannot be specified (the other party cannot be specified depending on how it is used, or the generality is lost by specifying it). The state was informed. For example, the detection status of human bodies (sometimes including fine movement) has been changed so that human body detection sensors for general-purpose use can use devices that require information without specifying a controller. It was configured to broadcast simultaneously in stages.

  As a specific example, in the standard of ECHONET (R) (see http://www.echonet.gr.jp/), which is one of the target networks, "Sensor class" is defined (refer to non-patent literature), and the human body detection status is defined as "announcement at the time of status change (notification)" (simultaneous broadcast message transmission when the status changes) is mandatory. ing.

  In such a standard, versatility may be emphasized, and the number of transmissions and the transmission period of “announcement notification (notification)” are not particularly specified. For this reason, when the system is assembled, the number of times of simultaneous transmission is held in advance, and “state change announcement (notification)” is performed based on the information.

  FIGS. 11 to 15 show the configuration of a communication control processing apparatus when performing a system to which the present invention is applied and a conventional general “announcement (notification) at state change”. FIG. 11 shows a configuration example of a communication system to which the present invention is applied, and FIG. 12 shows a configuration example of a communication control processing device (device and controller) related to a conventional “state change announcement (notification)”. FIG. 13 shows a configuration example of a state change information notification control processing unit related to a conventional “state change announcement”, and FIG. 14 shows a part of a telegram configuration when a state change to which the present invention is applied is notified. FIG. 15 shows an example of the configuration when a “state change announcement (notification)” is performed. The system to which the present invention is applied and the prior art will be described with reference to FIGS.

  In the network 110 to which the present invention is applied, when the device B 112 is a human sensor, when the device B 112 detects a person's movement (151 in FIG. 15), the human body detection of the device state management unit 121 (FIG. 12) 121 The device control processing unit 122 that detects this changes the state change information notification control processing unit 120 to notify the change in the human body detection state. The state change information notification control processing unit 120 that knows the change in the human body detection state generates a message for “announcement notification (notification)”, and sends it to the network 110 via the communication control processing unit 123 and the transmission / reception circuit unit 124. The broadcast is transmitted (152).

  As a message for “state change announcement (notification)”, for example, in the case of ECHONET®, as shown in FIG. 14, an ESV code part 141 for designating a request response notification, a request response notification target (information The EPC unit 142 that designates (type) and the EDT data unit 143 that indicates specific contents are included as constituent elements.

  In the example at the time of human body detection, the ESV unit 141 is 0x73 indicating notification, the EPC unit is 0xB1 (142b) indicating the human body detection state, and the EDT unit is 0x41 (143b) indicating the presence of human body detection. When some abnormality of the sensor other than human body detection is detected, for example, the EPC portion is 0x88 (142a), and if the EDT portion is abnormal, 0x41 (143a).

  The device information analysis processing unit 127 of the device A111 receives the state change notification message 152 via the transmission / reception circuit unit 125 and the communication control processing unit 126, and detects a state change (human body detection) in the device B112 (153). The system control processing unit 128 that has received the notification of human body detection from the device information analysis processing unit 127 performs notification of human body detection, for example, by interrupting the screen control of the controller.

  The series of “state change announcements” is based on the information in the notification count information holding unit 130 held in advance (may be set by communication or the like) in the state change information notification control processing unit 120 of the device B112. The same information is performed a plurality of times (154, 155).

  In general, multiple transmissions are generally notifications that do not require a response, and depending on the status of the network, it is not possible to confirm whether the information has reached the required target. is there. At this time, the device A111 such as the controller receives the notification of the state change many times (153, 155), and the operation of the controller is interrupted (interrupt) many times. It led to dissatisfaction.

Also, depending on the number of notifications of this state change, when the network transmission speed is slow, there is a high possibility of causing a situation in which unnecessary traffic increases and other information that is originally intended to be communicated cannot be communicated. . Also, if retransmission is not performed at all, once communication fails, the information does not reach a necessary device such as a controller, and the reliability of the system is lowered.
Echonet (R) Consortium issued, ECHONET (R) Standard Version 2.11, April 26, 2002, APPENDIX P.1-10, Part 2 P.5-7, Part 2 P.9-9

  As described above, in the conventional method and configuration, notification of the same information is repeatedly received on the controller side, and dissatisfaction such as user response on the controller side occurs, or the process is complicated to resolve the dissatisfaction. . Depending on the number of state change notifications, even if the controller receives the initial notification, unnecessary information is retransmitted many times, and unnecessary information is transmitted over the network. Depending on the situation, unnecessary traffic increases, and there is a possibility that a terminal that cannot transmit a necessary message may appear.

  On the other hand, if the number of notifications is set to one time, depending on the state of the network, it may not reach the controller and may not function as a system.

  An object of the present invention is to solve the above-described conventional problem, and to provide a communication control processing device that enables a notification of a state change or the like that is performed a plurality of times to be stopped from another device via communication. To do.

  In order to solve the above-described conventional problems, the communication control processing device and the program of the present invention stop the state change notification from another device when the device state change notification message is transmitted (retransmitted) by communication. Is received, a notification stop instruction information processing unit that performs processing to stop transmission (retransmission) of a state change notification message is analyzed.

  As a result, unnecessary notifications can be prevented on the notification transmission side, the processing load is reduced, and unnecessary increase in traffic on the network can be prevented.

  Further, the communication control processing device and the program according to the present invention are configured to analyze the content of a message for which communication stop has been specified, and after confirming the notification stop specification target, to perform processing to stop the notification of the currently specified notification It is what.

  As a result, even in a state where a plurality of state change information is being notified, the state change that requires notification is not stopped, and a plurality of state change information notifications can be realized without problems. is there.

  In addition, the communication control processing device and the program of the present invention analyze the contents of a message for which notification stop is specified, and after confirming the notification stop specification target and its stop notification information, stop the notification of the currently specified notification It is set as the structure which performs this process.

  In this way, if the status changes after the first notification and a notification of another status is received at the stage of receiving the notification stop notification message, the status change is notified without stopping the notification. It is something that can be done.

  In addition, the communication control processing device and program of the present invention analyzes the contents of a message for which notification stop has been specified, and the information of the device that has stopped notification is permitted to be notified to the other party (or to stop notification). In this case, the process of stopping the notification of the designated one that is currently being notified is performed only in the case of the other party).

  As a result, in a system in which a plurality of controllers are present, notification can be continued with respect to a partner that is desired to be explicitly received (notified of a state change) other than the controller that is generally present.

  In addition, the communication control processing device and program of the present invention, when receiving a status notification message from another device through communication, determines whether it is a status change notification of another device that needs to be processed, In some cases, it is configured to include another device state notification stop processing unit that returns a message instructing the device that has notified the state change to stop the notification.

  As a result, the notification receiving side does not receive the same notification over and over, and the processing load on the received message is reduced.

  In addition, the communication control processing device and program of the present invention, when receiving a status notification message from another device through communication, determines whether it is a status change notification of another device that needs to be processed, In some cases, a communication stop designation telegram in which information to be notified of stop designation is set is generated, and transmission processing is performed to the transmission source of the status notification telegram.

  As a result, when other devices have notification of multiple state change information, the notification can be stopped only in the already received state, so that it becomes impossible to receive notification of the necessary state change. It is possible to detect the state change without any trouble.

  In addition, the communication control processing device and program of the present invention, when receiving a status notification message from another device through communication, determines whether it is a status change notification of another device that needs to be processed, In some cases, a message is generated in which information on the communication stop request is entered as message data, and transmission processing is performed to the transmission source of the status notification message.

  Thus, when the notification source device is associated with the device that transmitted the notification stop, the associated device uses the notification from the notification source device without receiving an unnecessary notification. Coexistence with other devices will be avoided.

  In addition, the telegram for instructing to stop the notification of the state change processed by the communication control processing device and the program according to the present invention includes information to be notified.

  As a result, even when a plurality of state change notifications are generated in one device, it is possible to specify the stop of only one specific notification.

  In addition, the message designating the stop of the state change notification processed by the communication control processing device and the program of the present invention is configured to include notification stop target information and notification stop target information.

  As a result, even when the state changes in a short time with a single device, notification of a state that has not yet been transmitted is not erroneously stopped.

  In addition, the message designating the stop of the state change notification processed by the communication control processing device and the program of the present invention is configured to include information on the notification stop target and information on the notification stop request source.

  As a result, when there is a notification receiving device such as a controller using a plurality of notification information, it is possible to identify the device that must be notified and stop the notification.

  The communication control processing device and program according to the present invention can stop notification of a state change or the like due to simultaneous broadcasts that are performed a plurality of times via communication, which not only reduces unnecessary traffic but also on the transmission side. This also leads to a reduction in processing for the notification message of the receiving device.

  In the first aspect of the invention, when a message requesting to stop the status change notification is received from another device while transmitting (retransmitting) the status change notification message of the device by communication, the content is analyzed. By providing a notification stop instruction information processing unit that performs processing for stopping transmission (retransmission) of a state change notification message, unnecessary notification transmission can be prevented on the notification transmission side, and the processing load is reduced. The above traffic will be reduced.

  According to a second aspect of the present invention, the content of a message for which communication stop has been designated is analyzed, and after confirming the notification stop designation target, a process for stopping the notification of the designated target currently being notified is performed. Even when the state change information is being notified, the state change that needs to be notified is not stopped, and a plurality of state change information notifications can be processed in parallel.

  According to a third aspect of the present invention, the content of a message for which notification stop is specified is analyzed, and after the notification stop specification target and its stop notification information are confirmed, processing for stopping the notification of the specified target currently being notified is performed. If the status changes after the initial notification, and you are trying to notify another status when you receive the notification stop notification message, notify the status change without stopping the notification. Can do.

  According to a fourth aspect of the invention, the content of a message for which notification stop is designated is analyzed, and the information of the device that has stopped the notification is the destination that the user wants to notify (or the destination that is permitted to stop the notification). If the system is configured to stop the notification of the specified target that is currently being notified only when it is detected, it should be explicitly received in a system with multiple controllers other than the existing controller. Notification can be continued to the other party (who wants to be notified of a state change).

  In the fifth aspect of the present invention, when a status notification message is received from another device through communication, it is determined whether or not it is a status change notification of another device that needs to be processed. By providing a configuration that includes another device status notification stop processing unit that sends back a message instructing the device to stop notification, the notification receiving side will not receive the same notification over and over again. The processing load on received messages can be reduced.

  In the sixth aspect of the invention, when a status notification message is received from another device by communication, it is determined whether it is a status change notification of another device that needs to be processed. By generating a communication stop specification message with the information to be specified and sending it to the source of the status notification message, in a state where other devices have multiple status change information notifications, The notification can be stopped only in the received state, and the notification of other state changes from the same device cannot be received.

  In the seventh invention, when a status notification message is received from another device by communication, it is determined whether it is a status change notification of another device that needs to be processed. By generating a message containing the information of the requesting user as message data and performing transmission processing to the transmission source of the status notification message, the notification source device is associated with the device that sent the notification stop In this case, the associated device can coexist with other devices that use the notification from the notification source device without receiving an unnecessary notification.

  According to an eighth aspect of the present invention, even when a plurality of state change notifications are generated in one device, the message for instructing the stop of the state change notification includes the information to be notified. , You can specify only one specific notification stop.

  According to a ninth aspect of the present invention, a message specifying stop of notification of a state change includes a notification stop target information and a specific content of the notification stop target information. Even if the state changes, the notification of the state that has not yet been transmitted is not erroneously stopped.

  In a tenth aspect of the invention, a message specifying stop of notification of a state change includes a notification stop target information and a notification stop request source information. When there is a receiving device, the notification is not stopped when the notification has not yet arrived at the device that must be notified.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

FIG. 1 is a functional block diagram related to the present invention of a communication control processing device in a device that transmits a notification message according to the present invention, and FIG. 2 shows the present invention of a communication control processing device in a device that receives a notification message according to the present invention. FIG. 3 shows an example of a part of a message structure according to the present invention.

  In FIG. 1, the state change information notification control processing unit 120 includes a notification stop instruction information processing unit 10 in addition to the notification count information holding unit 130. In FIG. 2, the device A 111 has an other device state notification stop processing unit 20. In FIG. 3, in the case of a message specifying stop notification, for example, a code (30) of 0xFE is arranged in the information type specification 142, and notification stop instruction information 31 instructing notification stop is arranged in the data portion 143. Is done.

  The operation and operation of the device and the electronic message configured as described above will be described with reference to FIGS. 1, 2, 3, 16, 11, and 12.

  FIG. 4 is a diagram showing an example of a sequence according to the present invention. 40 indicates the internal processing on the side that receives the notification message, arrow 41 indicates the transfer of the message from the device that received the notification message to the device that sent the notification message, and 42 indicates the side of the device that transmits the notification message Indicates internal processing.

  In the network 110 to which the present invention is applied, when the device B 112 detects a human movement (151), the state of the human body detection in the device state management unit 121 changes, and the device control processing unit (see FIG. 12) detects this. 122 notifies the state change information notification control processing unit 120 of a change in the human body detection state. The state change information notification control processing unit 120 that knows the change in the human body detection state generates a message for “announcement notification (notification)”, and sends it to the network 110 via the communication control processing unit 123 and the transmission / reception circuit unit 124. The broadcast is transmitted (152).

  The device information analysis processing unit 127 of the device A111 receives the electronic message 152 via the transmission / reception circuit unit 125 and the communication control processing unit 126, and detects a state change (human body detection) in the device B112 (153). At this time, the device information analysis processing unit 127 has received the notification message, and passes the notification content to the system control processing unit 128 and also to the other device state notification stop processing unit (FIG. 2) 20. The other device status notification stop processing unit performs notification stop transmission processing (40) of constructing and transmitting a message in which the notification stop instruction code 32 (for example, 0xFF) is included in the notification stop designation information 31, and notifies from the device A111. A stop designation message is transmitted (41).

  In the device B 112, a message is passed to the state change information notification processing unit 120 via the transmission / reception circuit unit 124 and the communication control processing unit 123. In the state change information notification control processing unit 120 that receives this message, the notification stop instruction information processing unit (FIG. 1) 10 analyzes the message, determines that the notification stop is specified, and notifies the human body detection state notification. Is stopped (42).

  It should be noted that it is within the provisions of the present invention regarding whether or not a notification of stoppage is received once a predetermined notification is stopped and then restarted after a certain period of time (for example, in a device that detects contents that are clearly understood to be abnormal). For example, when anomaly detection has been notified, after the anomaly detection notification is stopped by an instruction to stop, the transmission is started again when the anomaly has not been released after a certain period of time).

  As described above, according to the present embodiment, it is possible to stop the notification of a state change or the like from being continuously performed from the outside, and the notification transmission side can prevent unnecessary notifications and processing load. And an unnecessary increase in traffic on the network can be prevented. Further, the notification receiving side does not receive the same notification over and over, and the processing load on the received message is reduced.

FIG. 1 is a functional block diagram related to the present invention of a communication control processing device in a device that transmits a notification message according to the present invention, and FIG. 2 shows the present invention of a communication control processing device in a device that receives a notification message according to the present invention. FIG. 5 shows an example of a part of a message structure according to the present invention.

  In the case of a message specifying stop notification in FIG. 5, for example, a code (30) of 0xFE is arranged in the information type specification 142, and notification stop instruction information 31 instructing notification stop is arranged in the data portion 143. Further, the content of the notification stop instruction information becomes a code 50 that specifies the information type to be stopped.

In the device and the telegram configured as described above, FIG. 1, FIG. 2, FIG. 5, FIG.
The operation | movement and an effect | action are demonstrated using FIG.

  FIG. 6 is a diagram showing an example of a sequence related to the present invention. In FIG. 6, 60, 63, and 67 indicate internal processing on the side that transmits the notification message, arrows 61, 65, and 68 indicate delivery of the notification message, and arrow 66 indicates notification from the device that received the notification message. It shows delivery of a message to the device that sent the message, and 62 and 64 show internal processing on the device side that receives the notification message.

  For example, the device B112 is a device having a function of notifying a plurality of states such as a gas water heater. In the network 110 (FIG. 12) to which the present invention is applied, when the device B 112 detects the hot water supply start state (60), the hot water supply state of the device state management unit 121 changes, and the device control processing unit 122 that detects this changes the hot water supply state. Then, the state change information notification control processing unit 120 is notified of a change in hot water supply state (hot water supply start). The state change information notification control processing unit 120 that knows the change in the hot water supply state generates a telegram for “state change announcement (notification)” notifying that the hot water supply start state has been entered, and the communication control processing unit 123, the transmission / reception circuit A telegram is transmitted to the network 110 simultaneously via the unit 124 (61).

  The device information analysis processing unit 127 of the device A111 receives the electronic message 61 via the transmission / reception circuit unit 125 and the communication control processing unit 126, and detects a hot water supply state change (hot water supply start) in the device B112 (62). At this time, the device information analysis processing unit 127 has received the notification message, and passes the notification content to the system control processing unit 128 and also to the other device state notification stop processing unit (FIG. 2) 20. The other device status notification stop processing unit 20 composes and transmits a message in which the notification stop specification information 31 includes the notification stop target PC code 50 (for example, 0x88 when the PC indicating the hot water supply status is 0x88). A notification stop transmission process (184) is performed to transmit a notification stop designation message from the device A111 (65).

  In the device B 112, a message is passed to the state change information notification processing unit 120 via the transmission / reception circuit unit 124 and the communication control processing unit 123. In the state change information notification control processing unit 120 that has received this message, the notification stop instruction information processing unit (in FIG. 1) analyzes the message, determines that it is a notification stop designation of the hot water supply state, and determines the hot water supply state. Is stopped (67).

  If the device B112 detects the gas leakage state (63) and receives the gas leakage state notification 185 before receiving the hot water supply state notification stop (66), the notification stop designation message is sent. Since what has been designated by 186 is the hot water supply state, the notification of the gas leakage state is performed after that (68). Thereby, for example, as shown in FIG. 6, even if the notification 65 of the gas leakage state that has occurred later cannot be received due to the internal state of the device A111, the state change notification 68 is received again from the device B112. Therefore, it can be recognized that the state of the device B 112 has changed.

  As described above, in the embodiment of the present invention, it is possible to stop from the outside by designating a target state that notifications such as state changes are continuously performed. Even in a state where notification of change information is being performed, there is no possibility of stopping until notification of a state change that requires notification. In addition, on the receiving side of notifications, when other devices have notifications of multiple state change information, it is possible to stop notifications only for the states that have already been received, and it will not be possible to receive notifications of necessary state changes. Is something that disappears.

(Embodiment 3)
FIG. 1 is a functional block diagram related to the present invention of a communication control processing device in a device that transmits a notification message according to the present invention, and FIG. 2 shows the present invention of a communication control processing device in a device that receives a notification message according to the present invention. FIG. 7 shows an example of a part of a message structure according to the present invention.

  In the case of a message specifying stop notification in FIG. 7, for example, a code (30) of 0xFE is arranged in the information type specification 142, and notification stop instruction information 31 instructing notification stop is arranged in the data portion 143. In addition, the content of the notification stop instruction information includes a PC code 50 to be stopped for notification and stop target notification content information 51.

  The operation and operation of the device and the electronic message configured as described above will be described with reference to FIGS. 1, 2, 7, 8, 11, and 12.

  FIG. 8 is a diagram showing an example of a sequence related to the present invention. In FIG. 8, 81 and 84 indicate internal processing on the side that transmits the notification message, arrows 82, 86, and 88 indicate delivery of the notification message, and arrow 87 transmits the notification message from the device that has received the notification message. A message is transferred to the original device, and 83, 85, and 89 indicate internal processing on the device side that receives the notification message.

  For example, it is assumed that the device B112 has two or more states within the same target such as an open / close sensor, and the probability of occurrence of both is the same. In the network 110 (FIG. 12) to which the present invention is applied, when the device B 112 detects an open state of a door or the like (81), the open / close state of the device state management unit 121 changes, and the device control processing unit detects this 122 notifies the state change information notification control processing unit 120 of the change in the open / close state (open state). The state change information notification control processing unit 120 that knows the change in the open / closed state generates a telegram for “announcement change notification (notification)” to notify that the state has been opened, and the communication control processing unit 123, the transmission / reception circuit unit A message is transmitted by simultaneous broadcast to the network 110 via 124 (82).

  The device information analysis processing unit 127 of the device A111 receives the telegram 82 via the transmission / reception circuit unit 125 and the communication control processing unit 126, and detects a hot water supply state change (hot water supply start) in the device B112 (83). At this time, the device information analysis processing unit 127 has received the notification message, and passes the notification content to the system control processing unit 128 and also to the other device state notification stop processing unit (FIG. 2) 20. In the other device status notification stop processing unit 20, the PC code indicating the open / closed state (for example, 0xE0 when the value is 0xE0) is entered in the notification stop target PC code 70 constituting the notification stop designation information 31, and the stop target In the notification content information 71, a notification stop transmission process (85) of composing and transmitting a message including a value indicating an open state is performed, and a notification stop designation message is transmitted from the device A111 (87).

  In the device B 112, a message is passed to the state change information notification processing unit 120 via the transmission / reception circuit unit 124 and the communication control processing unit 123. In the state change information notification control processing unit 120 that has received this message, the notification stop instruction information processing unit (FIG. 1) 10 analyzes the message and determines that the notification stop designation is in the open state. Is in the closed state (state change (closed) detection 104) and the state notification has already been transmitted (86), and the notification of the closed state is not stopped.

  Thus, for example, as shown in FIG. 8, even if the notification 85 of the open / closed state whose state has been changed later cannot be received due to the internal state of the device A111 or the like, the state change notification 88 is again received from the device B112. Therefore, it can be recognized that the state of the device B 112 has changed.

  As described above, in the embodiment of the present invention, it is possible to stop from the outside by designating a target state that notifications such as state changes are continuously performed, and on the notification transmission side, Even in a state where notification of state change information whose state changes in the meantime is performed, there is no possibility of stopping until notification of a state change of the state content that has not yet reached the other party.

  In addition, on the receiving side of notifications, when other devices have notifications of multiple state change information, it is possible to stop notifications only for the states that have already been received, and it will not be possible to receive notifications of necessary state changes. Is something that disappears.

  In the network 110 (FIG. 12) to which the present invention is applied, when the device B 112 detects a person's movement (101), the state of the human body detection in the device state management unit 121 changes, and the device control processing unit detects this 122 notifies the state change information notification control processing unit 120 of a change in the human body detection state. The state change information notification control processing unit 120 that knows the change in the human body detection state generates a message for “announcement notification (notification)”, and sends it to the network 110 via the communication control processing unit 123 and the transmission / reception circuit unit 124. The broadcast is transmitted (102).

  The device information analysis processing unit 127 of the device A111 receives the electronic message 102 via the transmission / reception circuit unit 125 and the communication control processing unit 126, and detects a state change (human body detection) in the device B112 (103). At this time, the device information analysis processing unit 127 has received the notification message, and passes the notification content to the system control processing unit 128 and also to the other device state notification stop processing unit (FIG. 2) 20. In the other device state notification stop processing unit, the PC code indicating the human body detection state (for example, 0x88 when the value is 0x88) is entered in the notification stop target PC code 90 constituting the notification stop designation information 31, and the notification stop. The original node information 91 is subjected to a notification stop transmission process (104) in which a message including information indicating the device A111 (for example, the address of the device A111) is entered and transmitted. A stop designation message is transmitted (105).

  In the device B 112, a message is passed to the state change information notification processing unit 120 via the transmission / reception circuit unit 124 and the communication control processing unit 123. In the state change information notification control processing unit 120 that has received this message, the notification stop instruction information processing unit (FIG. 1) 10 analyzes the message and determines that notification stop is specified. However, if it is necessary to confirm that the device A111 is received by the device C113, the state change notification is continuously transmitted without stopping the notification (106). In the above example, the node stop address is used as the notification stop source node information, but there may be information such as a manufacturer code that does not depend on the actual installation. The device C 113 can receive the state change notification message 106 and recognize the occurrence of the human body detection (107).

  As described above, in the embodiment of the present invention, in a system in which a plurality of controllers or the like operate upon receiving a status notification, the status transmission source can notify the other party that the status transmission source always wants to notify. The system configuration can be expanded (such as a controller is not limited to one).

  As described above, the communication control processing device and the program according to the present invention can increase the traffic due to unnecessary notifications and the state of the state at the notification source and the notification destination in the system in which the state change information is notified when the state of the device changes. This makes it possible to reduce inconveniences such as misalignment, and can be applied not only to notifications at the time of state changes but also to notifications of information using simultaneous broadcast communication.
