Abstract

A relay device (30) receives downstream messages to be sent to a smart meter, stores the received downstream messages, selects, on the basis of the levels of priority of the downstream messages, a high-priority downstream message to be sent to the smart meter with priority among the stored downstream messages, and sends the high-priority downstream message to the smart meter. A message transmission unit (21) sends a downstream message for which a level of priority has been specified, to the relay device (30). A priority level adjustment section (242) specifies an extraction condition used to extract a downstream message for which the level of priority is to be adjusted. The priority level adjustment section (242) also extracts a downstream message that satisfies the extraction condition, and generates a priority level adjustment message that instructs the relay device (30) to select a high-priority downstream message with a level of priority different from the level of priority already set for the extracted downstream message being given to the extracted downstream message. The message transmission unit (21) sends the priority level adjustment message to the relay device (30).

In addition, progress information management department 243 received in the file of number, priority adjustment index write " 0 " (zero) in transmission number, reception number, last time.

Progress information management department 243 is being transferred out whenever sending message and being sent by the message sending part 21 from message transceiver 20, makes corresponding transmission entrust the transmission number of the record of ID to increase progressively.

In addition, progress information management department 243 is being transferred out when the reception of message transceiver 20 entrusts receiving unit 22 to accept receipt message, makes corresponding transmission entrust the reception number of the record of ID to increase progressively, residue receipt message number is successively decreased.

In addition, progress information management department 243 according to certain certain intervals every, such as every 1 minute, accepting timing signal from timer portion 25, is that two-way transmission is entrusted for communication direction, calculate current inbound pacing, upgrade the file of the inbound pacing of precedence information form.

Now, the data copy of the file of reception number, before the file upgrading inbound pacing, was received the file of number by progress information management department 243 to last time.

Inbound pacing is by receiving number and the difference that received number last time is obtained divided by the interval of timing signal.

Priority adjustment part 242 uses the data of precedence information form, entrust for each transmission, judge that priority is the need of adjustment, if priority needs adjustment, then make priority adjustment message, the priority produced adjustment message is forwarded to message sending part 21.

Message sending part 21 sends priority adjustment message to specified relay 30.

Figure 14 is the process flow diagram of the example that the priority adjustment work implemented by priority adjustment part 242 is shown.

About the priority adjustment index of precedence information form, be assumed to be and entrust ID to become " 0 " (zero) for all transmissions.

Priority adjustment part 242 is transferred out by the regular timing signal coming self-timer portion 25.

The record (S11) of the initial transmission trust ID of precedence information form is read in priority adjustment part 242 first.

Now, in the file that the take over period carves when countless certificate (in S12 "No"), be judged as that priority does not need adjustment in limited time, the ensuing record (S11) sending trust ID is read in priority adjustment part 242.

Even if when having data in limited time in the file that the take over period carves (in S12 "Yes"), when priority adjustment index has become "+1 " (in S13 "+1 "), be judged as judging that priority is the need of adjustment, the ensuing record (S11) sending trust ID is read in priority adjustment part 242.

When priority adjustment index is " 0 " (in S13 " 0 "), priority adjustment part 242 execution priority, the need of adjustment check processing (S14), judges whether to carry out priority adjustment.

When being judged as that priority needs adjustment (in S15 "Yes"), priority adjustment part 242 is entrusted in the file of the priority adjustment index of ID in this transmission of precedence information form and is written as "+1 " (S16), makes priority adjustment message (S17) according to the transmission form of message of Figure 13.

Priority adjustment message is made for each relay 30.

Namely, in S11, record the transmission trust be read into comprise the multiple transmission message mailing to multiple intelligent instrument 40, when carrying out relaying by multiple relay 30 to the message communicating with these multiple intelligent instruments 40, priority adjustment part 242 generates priority adjustment message for each relay 30.

Entrust ID to the transmission in the leader portion of priority adjustment message, ID is entrusted in the transmission being placed in the record read in from precedence information form in S11.

In addition, to sending destination ID, put into relay ID, to News Category, put into and represent it is the class code that priority adjusts message.

In addition, to transmission message size, put into the size of priority adjustment message, to priority, put into " height ".

To the transmission message of data portion, put into priority adjustment index value ("+1 ").

Like this, priority adjustment part 242 makes priority adjustment message for all relays 30, and the priority produced adjustment message is forwarded to message sending part 21 (S18).

ID is entrusted for all transmissions of precedence information form in priority adjustment part 242, performs above step (S19).

Priority is adjusted message and is sent to relay 30 by message sending part 21.

Figure 15 is the process flow diagram of priority the need of an example of adjustment check processing of the S14 that Figure 14 is shown.

In fig .15, show when sending number and exceeding with the difference receiving number the certain level value predetermined, the example of the priority of the message that the transmission improving the object of the judgement as S14 is entrusted.

Figure 15 priority the need of adjustment check processing in, first, the transmission and reception number discrepancy threshold (S1411) of this application ID, from the application table shown in Fig. 7, is read in priority adjustment part 242.

Next, priority adjustment part 242 calculates the difference (S1412) of the reception number of the transmission number to the downstream message of relay 30 and the upstream message from relay 30, when its value has exceeded transmission and reception number discrepancy threshold (in S1413 "Yes"), the judgement (S1414) that priority of making adjustment is such.

On the other hand, when the value calculated does not exceed transmission and reception number discrepancy threshold (in S1413 "No"), make and do not adjust the such judgement of priority (S1415).

Like this, the priority of Figure 15 is applied in the multiple downstream message of transmission and then the two-way message communicating responding multiple upstream message the need of adjustment check processing.

In other words, the priority of Figure 15 is applied to complex response request downstream message the need of adjustment check processing and sends trust.

Figure 16 is the process flow diagram of priority the need of another example of adjustment check processing of the S14 that Figure 14 is shown.

In figure 16, show and when required message sink speed, improve the example of the priority of the message of the transmission trust of the object of the judgement as S14 lower than the pre-treatment residue receipt message number in order to prescribe a time limit quarter in the take over period in message sink speed.

Figure 16 priority the need of adjustment check processing in, first, prescribing a time limit according to the take over period and carve with the difference of current time and remain receipt message number in priority adjustment part 242, calculates and receive and required message sink speed (S1421) to complete before take over period in limited time quarter.

Next, the inbound pacing of inbound pacing and the precedence information form calculated is compared in priority adjustment part 242, when the inbound pacing calculated is larger (in S1422 "Yes"), the judgement (S1423) that priority of making adjustment is such.

On the other hand, when the inbound pacing calculated is little (in S1422 "No"), makes and do not adjust the such judgement of priority (S1424).

Like this, Figure 16 priority the need of adjustment check processing in, entrust for each transmission, measure the inbound pacing of upstream message, when the reception according to the inbound pacing upstream message measured continues, judge whether the reception of all upstream messages can complete before finishing receiving the time limit.

Then, using all upstream messages be received in finish receiving the time limit before the transmission that do not complete entrust object as priority adjustment.

The priority of Figure 16 the need of adjustment check processing, is applicable to complex response request downstream message and sends trust also in the same manner as the situation of Figure 15.

Figure 17 is the process flow diagram of priority the need of another example of adjustment check processing of the S14 that Figure 14 is shown.

In fig. 17, when tailing off the excess time shown when carving in limited time to the take over period, the example of the priority of the message that the transmission improving the object of the judgement as S14 is entrusted.

In the priority of Figure 17 the need of in adjustment check processing, first, the difference with current time is carved in limited time according to the take over period in priority adjustment part 242, calculates and receives excess time (S1431).

Next, priority adjustment part 242 is according to sending the difference of entrusting moment and take over period to carve in limited time, calculate total time of reception (S1432), when receive excess time fewer than the certain proportion (such as 10%) in transmission and reception moment (in S1433 "Yes"), the judgement (S1434) that priority of making adjustment is such.

On the other hand, when receive excess time few unlike the certain proportion (such as 10%) in transmission and reception moment (in S1433 "No"), make and do not adjust the such judgement of priority (S1435).

The priority of Figure 17 the need of adjustment check processing, is applicable to complex response request downstream message and sends trust also in the same manner as the situation of Figure 15 and Figure 16.

Next, carry out describing to the work of following situation: when being judged as that priority adjustment is carried out to 1 transmission trust 1 in priority adjustment part 242, the mode having had to improve priority carried out priority adjustment other send trust 2 and to carve be, when carving the late moment in limited time than the take over period sending trust 1, carry out priority adjustment for sending trust 2 in the mode reducing priority the take over period sending trust 2 in limited time.

When being judged as that priority adjustment is carried out for 1 transmission trust 1 in priority adjustment part 242, execution priority reduces process.

Figure 18 is the process flow diagram that priority reduces process.

Reduce in process in priority, first, the record (S21) of the initial transmission trust ID of precedence information form is read in priority adjustment part 242.

Now, in the file that the take over period carves in limited time when countless certificate (in S22 "No"), priority adjustment part 242 is judged as that priority does not need adjustment, reads in the ensuing record sending trust ID.

When having data in the file that the take over period carves in limited time (in S22 "Yes"), when priority adjustment index becomes "+1 " (in S23 "+1 "), the candidate becoming and send trust 2 is entrusted in this transmission.

The take over period that take over period quarter and the transmission trust 2 in limited time sending trust 1 is compared in priority adjustment part 242 carves (S24) in limited time, carving in limited time in the take over period sending trust 2 is when carving the late moment in limited time than the take over period sending trust 1, for transmission trust 2, be judged as priority adjustment (in S25 "Yes") needing priority to reduce.

Reduce in process in priority, the transmission of precedence information form entrusts the file of the priority adjustment index of 2 to be modified to " 0 " (S26) by priority adjustment part 242, makes priority adjustment message (S27) according to the transmission form of message of Figure 13.

Now, ID is entrusted to the transmission in leader portion, put into the transmission sending trust 2 and entrust ID.

To the transmission message of data portion, put into priority adjustment index value (" 0 ").

Like this, priority adjustment part 242 makes priority adjustment message to all relays 30, and the priority produced adjustment message is forwarded to message sending part 21 (S28).

ID is entrusted in all transmissions for precedence information form, performs above step (S29).

In addition, the priority adjustment message made in S27 makes invalid to the priority adjustment message (describing the priority adjustment message of "+1 " in data portion) of relay 30 transmission order for sending trust 2, is equivalent to the example of invalid command.

Next, the structure of relay 30 and the work of priority adjustment are described.

Fig. 3 is the system construction drawing of the structure example that relay 30 is shown.

In figure 3, downstream message acceptance division 37 receives the message from message transceiver 20.

Downstream message acceptance division 37, except mailing to the downstream message of intelligent instrument 40, also receives priority adjustment message (directive command), also plays function as directive command acceptance division.

The priority of priority acccess control handling part 35 control message relaying.

Priority acccess control handling part 35 is made up of the priority change portion 352 of the down queue 351 of each priority and upstream queue 353 and the process of carrying out priority change.

Down queue 351, the upstream queue 353 of priority acccess control handling part 35 are made up of the multiple queues for each priority, but also can be realized by 1 queue.

In addition, also down queue 351 and upstream queue 353 can be realized by 1 queue.

Down queue 351 is equivalent to the example of downstream message storage part.

In addition, upstream queue 353 is equivalent to the example of upstream message storage part.

And then priority change portion 352, together with downstream message sending part 31, is equivalent to the example of preferential downstream message selection portion.

In addition, priority change portion 352, together with upstream message sending part 38, is equivalent to the example of preferential upstream message selection portion.

Downstream message is sent to intelligent instrument 40 by downstream message sending part 31.

Downstream message sending part 31 selects the downstream message put aside in the down queue 351 that priority is the highest, and selected downstream message is preferentially sent to intelligent instrument 40.

Therefore, downstream message sending part 31 is equivalent to the example of preferential downstream message selection portion.

Upstream message acceptance division 32 receives the upstream message from intelligent instrument 40.

Upstream message is sent to message transceiver 20 by upstream message sending part 38.

Upstream message sending part 38 selects the upstream message put aside in the upstream queue 353 that priority is the highest, and selected upstream message is preferentially sent to message transceiver 20.

Therefore, upstream message sending part 38 is equivalent to the example of preferential upstream message selection portion.

Priority change data store 36 is stored in the priority change information form (Fig. 6) of reference when priority acccess control handling part 35 carries out the judgement of priority change.

Information on load generating unit 33 generates the information on load of relay 30.

34 pairs, timer portion information on load generating unit 33 provides the timing signal of the generation of information on load.

The details in information on load generating unit 33 and timer portion 34 is described in embodiment 2.

The downstream message that receives from message transceiver 20 according to priority described in leader portion, is inserted the most end of down queue 351 by downstream message acceptance division 37.

In addition, priority, when receiving priority adjustment message, is adjusted message and outputs to priority change portion 352 by downstream message acceptance division 37.

Downstream message sending part 31 takes out downstream message from the beginning of the highest queue of the priority down queue 351.

When the queue that priority is the highest is empty, downstream message sending part 31 takes out downstream message from the beginning of the secondary high queue of priority.

Next, downstream message sending part 31, to the intelligent instrument 40 shown in the sending destination ID in downstream message, sends the downstream message taken out.

The upstream message that receives from intelligent instrument 40 according to priority set in leader portion, is inserted the most end of upstream queue 353 by upstream message acceptance division 32.

Upstream message sending part 38 takes out upstream message from the beginning of the highest queue of the priority upstream queue 353.

When the queue that priority is the highest is empty, take out upstream message from the beginning of the secondary high queue of priority.

Next, taken out upstream message is sent to message transceiver 20 by upstream message sending part 38.

In addition, when identical timing exists multiple upstream message of the transmission trust ID shared, upstream message sending part 38 is concentrated multiple upstream message and sends multiple upstream message with the form that the message sink shown in Figure 12 is entrusted.

Downstream message acceptance division 37 is described above, when receiving priority adjustment message from message transceiver 20, priority is adjusted message and outputs to priority change portion 352, recall priority change portion 352.

When there is not transmission trust ID set in the leader portion of priority adjustment message in the priority change information form (Fig. 6) of priority change data store 36, priority change portion 352 is according to the information in leader portion, and the project of ID is entrusted in new this transmission additional.

Next, priority change portion 352, with reference to the priority adjustment index value ("+1 " or " 0 ") of the data portion of priority adjustment message, when different from the value of preserving in priority change data store 36, is upgraded.

Figure 25 and Figure 27 is the figure of the example that priority change information form is shown.

The meaning of each table entries of priority change information form is identical with the precedence information form (Fig. 4) of message transceiver 20.

Figure 24 and Figure 26 illustrates that priority change portion 352 changes the figure of the situation before and after priority.

In Figure 24 and Figure 26, illustrate that priority is the example of this three phases high, medium and low.

Figure 24 illustrates the situation in the down queue 351 of the relay 30 under certain time point, and Figure 25 illustrates the situation of the priority change information form under the time point of Figure 24.

Such as, in the queue (height) of priority=high, put into the downstream message sending and entrust ID=0002.

In addition, successively queue (in) in put into send entrust ID=0003 downstream message, queue (low) put into send entrust ID be 0004,0001,0004 downstream message.

In addition, in priority change information form, store the data that Figure 25 is such.

Now, consider that downstream message acceptance division 37 receives to send and entrust ID=0001 and the situation of the priority of priority adjustment index=+ 1 adjustment message (symbol 701 of Figure 26).

Owing to entrusting the priority adjustment index file of ID=0001 to put into " 0 " (Figure 25) to the transmission of priority change information form, so priority adjustment index changes.

By receiving priority adjustment message, priority change information form is updated as shown in figure 27.

Priority change portion 352 input priority adjustment message (symbol 701 of Figure 26), take out the downstream message (symbol 702 of Figure 26) that ID=0001 is entrusted in the transmission of putting in queue (low), according to the instruction of priority adjustment index=+ 1, this downstream message is inserted priority higher leveled queue (in) most end.

Similarly, priority change portion 352 entrusts the upstream message (not shown) of ID=0001 to the transmission of putting in upstream queue 353, also insert the higher leveled queue of priority (in) most end.

Downstream message acceptance division 37 and upstream message acceptance division 32 are when receiving new message (symbol 703 of such as Figure 26), the priority adjustment index sending the record of entrusting ID=0001 is read from priority change information form, according to this instruction (+1), new message is inserted priority higher leveled queue (in) most end.

Then, downstream message sending part 31 takes out downstream message from the down queue 351 undertaken after the adjustment of the priority of downstream message by priority change portion 352.

Such as, in the down queue 351 shown in Figure 26, entrust the downstream message (symbol 704) of ID=0002 if take out to send, then in queue (height), there is not downstream message, so queue (in) in downstream message be removed.

Send and entrust the downstream message (symbol 702,703) of ID=0001 before carrying out the adjustment of priority by priority change portion 352, put aside in queue (low), so till being taken out by downstream message acceptance division 37, need long-time.

But, after adjusting priority by priority change portion 352 because send entrust the downstream message (symbol 702,703) of ID=0001 put aside in queue (in), so be removed at short notice.

Like this, priority change portion 352 extracts the downstream message that ID is entrusted in the transmission set shown in priority adjustment message from the downstream message stored down queue 351.

Then, priority change portion 352, when downstream message sending part 31 takes out downstream message from down queue 351, carries out the adjustment using the priority different from priority set in this downstream message such for the downstream message extracted.

Similarly, priority change portion 352, from the upstream message stored upstream queue 353, extracts the upstream message that ID is entrusted in the transmission set shown in priority adjustment message.

Then, priority change portion 352, when upstream message sending part 38 takes out upstream message from upstream queue 353, carries out the adjustment using the priority different from priority set in this upstream message such for the upstream message extracted.

In addition, in the present embodiment, priority change portion 352 does not change priority described in the message, and message is stored into the queue of the priority higher than original priority, but can rewrite the priority self of message yet.

As described above, in the present embodiment, according to the progress extent that the difference of the transmission and reception number of the two-way news in message transceiver 20, message sink speed, message sink represent excess time, message transceiver 20 uses priority adjustment index and indicates priority change to relay 30.

In addition, relay 30, according to priority adjustment index, changes the priority of the message retained in the queue of up, descending both sides.

Therefore, it is possible to misalign the device 30 that continues to apply excessive load ground, the priority of control message communication effectively.

In addition, the transmission that message transceiver 20 is entrusting the take over period specified more early to carve in limited time for the transmission relatively having carried out priority adjustment in the mode improving priority is entrusted, when carrying out priority adjustment in the mode improving priority, to reduce the mode of priority, carry out priority adjustment.

Therefore, it is possible to carry out the two priority classes of extremely careful message communicating.

Above, in the present embodiment, following intelligent instrument automatic look-up table system is described:

Comprise: intelligent instrument, relay, message transceiver, application service apparatus 10,

Intelligent instrument measures the use amount of electric power, coal gas, tap water etc.,

Between the application of more than 1 that application service apparatus 10 works and intelligent instrument,

Via the message transceiver be equipped with in centring system and the relay be equipped with between message transceiver and intelligent instrument, carry out the intelligent instrument automatic look-up table system of message communicating.

In addition, in the present embodiment, describe

The message sent data transmitting/receiving device that is applied on application service apparatus 10 sends to entrust and comprises the information that the take over period carves in limited time,

Data transmitting/receiving device possess keep application with intelligent instrument between message communicating progress information progress information management department and have according to the progress information of message communicating judge priority the need of adjustment the priority acccess control handling part to the priority adjustment part that relay indicates priority to adjust

In addition, in the present embodiment, describe

The priority change portion of the priority acccess control handling part that relay possesses

Change the priority to the process of the down direction message from data transmitting/receiving device to relay,

And then, when the object message of the priority adjustment instruction from message transceiver is two-way news, change the priority of the process to the up direction message from relay to data transmitting/receiving device.

In addition, in the present embodiment, describe

The progress information management department of the priority acccess control handling part that data transmitting/receiving device possesses

As the progress information of message communicating, keep coming each message of self-application send the transmission number of trust and receive number,

The priority adjustment part of the priority acccess control handling part that data transmitting/receiving device possesses

When sending number and having exceeded with the difference receiving number the certain level value predetermined, to improve the mode of the priority of the message that will send in this transmission is entrusted, to the adjustment of relay instruction priority.

In addition, in the present embodiment,

As the progress information of message communicating, keep coming each message of self-application to send message sink speed and the residue receipt message number of trust,

When message sink speed lower than in order to remain in the pre-treatment in limited time quarters take over period receipt message number and required message sink speed, to improve the mode of the priority of the message that will send in this transmission is entrusted, to the adjustment of relay instruction priority.

In addition, in the present embodiment,

As the progress information of message communicating, keep the transmission accepting message transmission trust to entrust and accept moment and the excess time carving to the take over period in limited time,

Excess time carving in limited time to the take over period is lower than under sending a certain proportion of situation of entrusting and accepting the time that moment to the take over period carves in limited time, to improve the mode of the priority of the message that will send in this transmission is entrusted, to the adjustment of relay instruction priority.

In addition, in the present embodiment, describe

The priority acccess control handling part that data transmitting/receiving device possesses

It is when carving the Zao moment in limited time than the take over period of other application above-mentioned that the message of carrying out priority adjustment in the mode wanting to improve priority sends that the take over period of entrusting carves in limited time,

Carry out priority adjustment instruction to reduce the priority of the message of other application transmission above-mentioned.

Embodiment 2.

In embodiment 1, message transceiver 20 when priority being adjusted message and is sent to multiple relay 30, to all relays 30 in identical timed sending priority adjustment message.

In the present embodiment, performance, the load condition of priority adjustment part 242 according to relay 30 are described, adjust the work of the order sending priority adjustment message to relay 30.

As shown in Figure 2, the structure example of the relay 30 of present embodiment as shown in Figure 3 for the structure example of the message transceiver 20 of present embodiment.

In addition, in the present embodiment, in message transceiver 20, priority adjustment part 242, for each relay 30, judges the processing load of the process for downstream message and upstream message.

Then, priority adjustment part 242 sends the mode of priority adjustment message with the relay 30 high from processing load, determines the sending order of the priority adjustment message in multiple relay 30.

In the present embodiment, priority adjustment part 242 also plays function as sending order determination section.

In addition, message sending part 21, according to the sending order determined by priority adjustment part 242, sends priority adjustment message to multiple relay 30.

Fig. 8 illustrates that priority adjustment part 242 adjusts precedence information form when sending the order of priority adjustment message to relay 30.

The priority adjustment form of Fig. 8 is in the precedence information form of Fig. 4, has added the form of the file of relay load level.

File beyond relay load level is identical with the precedence information form of Fig. 4.

Relay load level represents the load level of the relay sending priority adjustment message, and mean that value is larger, load level is higher.

Such as, when relay load level is " 3 ", represent the relay 30 being greater than " 3 " for load level, have sent priority adjustment message.

" 0 " (zero) represents that having have sent priority for all relays 30 adjusts message.

When the value of the relay load level of priority adjustment form is " 3 ", the load level for aftermentioned relay load form (Figure 10) is the relay 30 of " 3 ", sends priority adjustment message.

Next, the value of the relay load level of priority adjustment form is decremented to " 2 ", and the load level for relay load form (Figure 10) is that the relay 30 of " 2 " sends priority adjustment message.

Like this, the value of the relay load level of priority adjustment form is successively decreased, and sends priority adjustment message from the relay 30 that load level is high successively.

In addition, below, for the purpose of simplifying the description, what the value of relay load level of priority adjustment form was set in " 1 " and " 0 " is some.

Therefore, the load threshold value of aftermentioned relay specification form (Fig. 9) is only 1.

When relay load level priority being adjusted form is set to such as " 0 ", " 1 ", " 2 ", " 3 ", the load threshold value of relay specification form (Fig. 9) becomes 3 stages (from " 0 " to the threshold value of " 1 ", from " 1 " to the threshold value of " 2 ", from " 2 " to the threshold value of " 3 ").

Information on load reservoir 23 possesses relay load form as shown in Figure 10.

Relay ID is the ID identifying relay 30 uniquely.

Relay model ID is the ID of the model identifying this relay 30 uniquely.

Reservation message number is the message count retained in the upstream queue 353 and down queue 351 of this relay 30, represents the load condition of relay 30.

Relay 30 sends reservation message number and as information on load message to message transceiver 20 termly.

The load condition of load level to relay 30 obtains by horizontal division.

The value of load level is higher, represents that the load of relay 30 is higher.

In load level history, when load level is updated, the load level before renewal is described.

Information on load reservoir 23 possesses relay specification form as shown in Figure 9.

Relay specification form, for all relays 30 used in intelligent instrument automatic look-up table system, for each model of this relay, keeps the information of specification.

Relay model ID is the ID of the model identifying relay 30 uniquely.

Relay model is the model number of giving relay 30.

Load threshold value be for each relay model each set by, the threshold value of reservation message number, when the reservation message number under certain time point has exceeded this threshold value, be judged as that the load of this relay 30 is high.

Process handling capacity for set by each relay model, the message handling ability of relay 30.

Receive and entrust receiving unit 22 when accepting information on load message from relay 30, the data of the reservation message number in message are written to the file of the reservation message number of the corresponding relay 30 of the relay load form of information on load reservoir 23.

In the present embodiment, as an example, priority adjustment part 242 is when sending priority adjustment message to relay 30, the load condition according to relay 30 sent according to two stages.

Therefore, the relay load level of precedence information form is described above, gets the some values in " 1 " and " 0 ", and in precedence information form, new production is for when sending the record of trust, is initialized as " 0 ".

Figure 19 is the process flow diagram that priority adjustment part 242 adjusts when sending the order of priority adjustment message to relay 30.

Priority adjustment part 242, first according to the value of reservation message number, upgrades the load level of relay load form (Figure 10) and the information (S31) of load level history.

Next, the record (S32) of the initial transmission trust ID of precedence information form is read in priority adjustment part 242.

Now, in the file that the take over period carves in limited time when countless certificate (in S33 "No"), priority adjustment part 242 is judged as that priority does not need adjustment, reads in the ensuing record (S32) sending trust ID.

In the file that the take over period carves in limited time, have data (in S33 "Yes") and priority adjustment index be " 0 " situation (in S34 " 0 ") under, priority adjustment part 242 execution priority, the need of adjustment check processing (S35), judges whether to carry out priority adjustment.

Priority is identical with the S14 of Figure 14 the need of adjustment check processing (S35), such as, carries out the process shown in Figure 15 ~ Figure 17.

When being judged as that priority needs adjustment (in S36 "Yes"), priority adjustment part 242 is entrusted in the file of the priority adjustment index of ID in this transmission of precedence information form and is written as "+1 ", and then in the file of relay load level, be written as " 1 " (S37).

Next, priority adjustment part 242 execution priority adjustment Message Processing (1), the relay 30 high to load sends priority adjustment message (S38).

On the other hand, in the file that the take over period carves in limited time, have data (in S33 "Yes") and priority adjustment index become "+1 " situation (in S34 "+1 ") under, priority adjustment part 242 is with reference to relay load level (S40).

When relay load level is " 0 " (in S40 " 0 "), be judged as having sent priority adjustment message to all relays 30, priority adjustment part 242 is read in the ensuing of precedence information form and is sent the record of entrusting ID.

When relay load level is " 1 ", priority adjustment part 242 is after being updated to " 0 " by relay load level (S41), execution priority adjustment Message Processing (2), sends priority adjustment message (S42) for the relay 30 not yet sending priority adjustment message.

All transmissions of the 242 pairs of precedence information forms in priority adjustment part entrust ID to perform above process (S39).

Figure 20 is the reservation message number according to relay 30, and priority adjustment part 242 adjusts process flow diagram when sending the order of priority adjustment message to relay 30, relay load form update process (S31).

The record (S3111) of the initial relay ID of relay load form (Figure 10) is read in priority adjustment part 242 first.

Next, the value of the load level file in read in record is written to the load level history file (S3112) of the respective record of relay load form by priority adjustment part 242.

Next, the value of the relay model ID file in read in record as key word, is read the load threshold value (S3113) of corresponding relay model by priority adjustment part 242 from relay specification form (Fig. 9).

Next, reservation message number and the load threshold value (S3114) of relay load form are compared in priority adjustment part 242, when reservation message number is greater than load threshold value (in S3115 "Yes"), in the load level file of the respective record of relay load form, write " 1 " (S3116).

On the other hand, when reservation message number is not more than load threshold value (in S3115 "No"), in the load level file of the respective record of relay load form, write " 0 " (zero) (S3117).

All relay ID of the 242 pairs of relay load forms in priority adjustment part perform above process (S3118).

The record (S3121) of the initial relay ID of relay load form (Figure 10) is read in priority adjustment part 242 first.

Next, the value of the load level file in read in record is written to the load level history file (S3122) of the respective record of relay load form by priority adjustment part 242.

Next, the value of the relay model ID file in read in record as key word, is read the process handling capacity (S3123) of corresponding relay model by priority adjustment part 242 from relay specification form.

Next, priority adjustment part 242, according to the reservation message number of relay load form and process handling capacity, calculates Message Processing required time (S3124).

When the threshold value of Message Processing required time ratio as the Message Processing required time predetermined calculated is larger, in the load level file of the respective record of relay load form, write " 1 ", when less, write " 0 " (zero) (S3125, S3126).

But, also the Message Processing required time predetermined can not be used, and use as other decision method inferior: for the relay 30 of the large half of the Message Processing required time in all relays 30, load level file is become " 1 ", the load level file of remaining relay 30 is become " 0 ".

Figure 22 is the process flow diagram of priority adjustment Message Processing (1) (S38) of Figure 19.

Priority adjustment Message Processing (1) adjusts in priority adjustment part 242 in the process of the order sending priority adjustment message to relay 30 and is performed.

In priority adjustment Message Processing (1), the record (S3801) of the initial relay ID of relay load form (Figure 10) is read in priority adjustment part 242 first.

When load level file is " 0 " (in S3802 " 0 "), priority adjustment part 242 is judged as not sending priority adjustment message to corresponding relay 30, reads in ensuing record.

When load level file is " 1 " (in S3802 " 1 "), priority adjustment part 242 makes priority adjustment message (S3803), and the priority produced adjustment message is forwarded to message sending part 21 (S3804).

All relay ID of the 242 pairs of relay load forms in priority adjustment part perform above process (S3805).

Figure 23 is the process flow diagram of priority adjustment Message Processing (2).

Priority adjustment Message Processing (2) adjusts in priority adjustment part 242 in the process of the order sending priority adjustment message to relay 30 and is performed.

In priority adjustment Message Processing (2), the record (S4201) of the initial relay ID of relay load form (Figure 10) is read in priority adjustment part 242 first.

When load level history file is " 1 " (in S4202 " 1 "), priority adjustment part 242 is judged as have sent priority adjustment message to corresponding relay 30, reads in ensuing record.

When load level history file is " 0 " (in S4202 " 0 "), make priority adjustment message (S4203), the priority produced adjustment message is forwarded to message sending part 21 (S4204).

All relay ID of the 242 pairs of relay load forms in priority adjustment part perform above process (S4205).

Next, the work of the information on load generating unit 33 of relay 30 is described.
