Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic notification method or apparatus for connecting a plurality of terminals, and more particularly to an automatic notification method or apparatus for reducing the number of times of retransmission of notification data.

[0002]

2. Description of the Related Art For example, in a gas leak alarm system shown in FIG. 10 for monitoring a gas meter with a microcomputer (hereinafter referred to simply as a gas meter), an automatic notification device (hereinafter referred to as a transmission controller) is attached to each home and the transmission controller 3 is attached to the home. The telephone and the gas meter 1 are connected to each other, and gas leak detectors are connected to the gas meter 1, respectively, and the transmission controller 3 communicates with the designated report destination A (hereinafter referred to as center A) or center B via the telephone line switch 5. To do.

Further, the transmission controller 3 has a terminal calling function, and at a preset date and time, occupies a telephone line and sends meter reading data of a gas meter connected at a predetermined timing, and the center side If it cannot be received, it is sent again after a predetermined time. This retransmission is 11 times at maximum.

The retransmission timing will be described below with reference to the drawings. 11 and 12 are timing charts for explaining a conventional data transmission sequence.
FIG. 11 shows a system in which the data of the gas meter 1 is sent to the center A and then sent to the center B, and FIG.
And a method of simultaneously sending the data of the gas meter 1 to the center B will be described.

For example, the transmission controller 3 reads the meter-reading data of the gas meter 1 when the notification date designated in advance is reached, and writes the telephone number of the notification destination, the controller number, the gas meter number, etc. together with the meter-reading data in a predetermined message format. Then, it is sent out as shown in FIG. The data of this message is designated as A1 in FIG.

[0006] For example, when the center A, which is the report destination, transmits the data A1 (A is the report center number, 1 is the gas meter number) and is not received due to any reason, the controller waits for a predetermined time. , Data A1 is retransmitted (hereinafter referred to as a retry). When this retry is not received again, the controller re-enters the second data A1.
To retry.

As described above, when the center side does not receive the data even after resending, the data A is retried up to 11 times as shown in FIG. 11A, and then the center B is retried. Similarly, the telephone number of the center B, the controller number, the gas meter number, etc. are written together with the meter reading data in a predetermined telegram format, and sent to the center B as notification data. The data of this message is also shown in Fig. 1.
In 1 (a), B1 (B is the report center number,
1 is the gas meter number).

Next, for example, if the center B, which is the report destination, fails to receive the data B1 when it sends the data B1, the controller retries the data B1 after a predetermined time, and the data B1 is again unreceived. If so, the controller retries the second data B1 again.

As described above, when the center side does not receive the data even if it is retransmitted to the center B, the retry is similarly performed, and the retry is performed up to 11 times.

Further, as shown in FIG. 11B, for example, if the center A can receive the data in the third retry (retransmission) when the data A1 is transmitted, then the data B1 is transmitted to the center B. Send in the same way, Center B
If it is not received by the side, retry in the same way,
I was trying up to 11 times.

In addition, data A for both centers
1 and data B1 are transmitted simultaneously, the method shown in FIG.
As shown in (a) of 2, when the data A1 and the data B1 are transmitted at the time of one transmission and, for example, both centers are not received due to some reason, the transmission controller 3 waits for a predetermined time, When the data A1 and the data B1 are paired and retried, and the reception is not received again, the controller restarts again.
The data A1 and the data B1 for the second time are retried.

In this way, even if the data is retransmitted to the center A and the center B, if it is not received by the center side,
Similarly, a set of data A1 and data B1 was retried and retried up to 11 times.

Further, as shown in FIG. 12B, for example, if the center A is able to receive the data in the third retry (retransmission) when the data A1 and the data B1 are transmitted as a set, the next time, When the data B1 is similarly transmitted to the center B, and the data is not received on the side of the center B, the same retry is performed, and the data B1 is retried from the first time until the transmission is 11 times. .

[0014]

However, in recent years, there is a tendency that a plurality of gas meters are attached to the transmission controller as shown in FIG.
For example, if multiple gas meters are attached to a transmission controller that sends data to one center and then sends data to the other center, the maximum number of retries is 11.
As shown in (a) of FIG. 13, for example, assuming that the center A can receive at the third retry, the data A2 of the next gas meter 2 is sent out, and from this time, something is done. When the center A does not receive the data due to the above reason, the data A2 is sent from the first time, so that the retry is performed up to 11 times (12 times including the first time) again.

Further, when a plurality of gas meters are attached to the transmission controller of the system of simultaneously reporting to the center A and the center B, data A1 and data B1 or data A
Even if two sets of data 2 and data B2 are transmitted at the same time, the maximum number of retries is 11, so that as shown in (b) of FIG. Is not received, data B1
Is 12 times counting from the first time (11 retransmissions) while not receiving
When the data A2 and the data B2 are transmitted at the same time in one set, for example, when both centers are not received for some reason, the maximum number of retries is set to 11 times. As shown in (b) of, the transmission will be performed 12 times (retransmission 11 times) from the first time.

That is, when a plurality of gas meters are attached to the transmission controller which has a maximum of 11 retries,
When the data of the first gas meter is sent, the data of the second gas meter is sent to the same address even though the data was not received even if the retry was performed up to 11 times while the address was not received. However, there is a problem in that the power of the battery is wastefully consumed because the same sequence is transmitted.

When the transmission controller transmits data, the terminal calling circuit electrically connected to the telephone line occupies the telephone line, and therefore the user cannot make a call. It will be.

For this reason, when the conventional transmission sequence is adopted in a transmission system in which a plurality of gas meters are attached and the number of report destinations is also plural, it is not possible to retry a maximum of 11 times while the report destination is not receiving. Despite being received, the data of the second gas meter is sent to the same report destination in the same sequence, so that the user may not be able to make a call for a very long time. was there.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain an automatic notification device capable of reducing the total number of retries even if a plurality of gas meters are attached and the number of notification destinations is plural. .

[0020]

According to the automatic notification method for connecting a plurality of terminals according to the present invention, when a plurality of terminals are connected and a cause of a notification to a notification destination connected to a telephone line occurs, the terminals are notified. An automatic notification method of sequentially transmitting notification data via a telephone line, and when the notification destination cannot receive the notification data, a step of resending the notification data,
When the notification data is retransmitted, the step of counting the number of times by adding it to the number of times the previous notification data was retransmitted to the notification destination, and when the count value reaches a predetermined value, the notification data of the same notification destination And a step of stopping the transmission.

Further, the automatic alerting apparatus according to the present invention, which is connected to a plurality of terminals, has a plurality of terminals connected to each other and causes a call to a callee connected to a telephone line, as shown in FIG. An automatic reporting method connected to a telephone line, comprising: a reporting data creating means 10 for producing reporting data of a terminal; and a reporting data transmitting means 12 for transmitting reporting data via a telephone line. When the destination cannot receive the report data, the report data is read from the report data creating unit 10 and the report data retransmitting determination unit 13 that retransmits the report data from the report data transmitting unit 10 is counted together with the retransmitting of the report data. When the number of retransmissions of the previous notification data to the report destination is read and the count value is added to the number of retransmissions, the number of retransmissions measurement means 14, and when the added count value reaches a predetermined value, Transmission stop determining means stops the transmission of the notification data to the same report destination from the transmission unit 12 1
5 and 5.

Further, the automatic notification method or the apparatus thereof, when transmitting the notification data, transmits the notification data for one notification destination or the notification data for a plurality of notification destinations at the time of transmission.

Furthermore, the automatic notification method or its apparatus deletes the notification data when the communication data corresponding to the terminal is received by the specified notification destination.

[0024]

In the automatic notification method for connecting a plurality of terminals of the present invention, when the notification data of a plurality of connected terminals is transmitted when a notification factor occurs and the notification destination cannot be received, the notification data is received. Is retransmitted, and it is determined whether or not the number of times the number of retransmissions of the previous notification data to the notification destination is added is a predetermined value. When it is determined that the value is the predetermined value, the transmission of the notification data to the notification destination is stopped.

In addition, in the automatic reporting apparatus to which a plurality of terminals are connected according to the present invention, when a reporting factor occurs, the reporting data creating means creates reporting data of a plurality of connected terminals, and the reporting data transmitting means. Thus, this notification data is transmitted in sequence.

When the notification destination cannot be received, the notification data resend determination means retransmits the notification data from the notification data transmission means, and the resend count measurement means
When the number of retransmissions to the notification destination is added to the number of retransmissions of the previous notification data and reaches a predetermined value, the transmission stop means
Transmission of report data to the report destination is stopped.

Further, when the notification data is transmitted, since the notification data for one notification destination or the notification data for a plurality of notification destinations is transmitted at the time of transmission, there may be one or more notification destinations. , Will be communicated.

Further, when the communication data corresponding to the terminal is received by the designated notification destination, the notification data is deleted, so that the number of notification data in one transmission is reduced.

[0029]

EXAMPLE This example will be described as an example of use in a gas meter. FIG. 2 is a schematic configuration diagram of an embodiment of the automatic notification device of the present invention. FIG. 3 is a schematic configuration diagram of a gas leak detection system using the automatic notification device, in which the designated notification destinations A, B, C and the backup notification destinations a, b, c are the transmission controller of the present embodiment and the switch 5. Connected through.

In the figure, reference numeral 20 designates telephone lines L1 and L2.
Is a rectifier circuit that is connected to and rectifies the signal from this line. A selector switch 21 is provided between the rectifier circuit 20, the terminal calling circuit 22, and the no ringing communication circuit 25, and connects the rectifier circuit 20 to any of them by being switched. When the telephone line is not used, the terminal calling circuit 22 sends the set notification data in a predetermined electronic message format.

Reference numeral 23 is connected to the terminal calling circuit 22 or the no ringing communication circuit 25 through a coil in a transformer-coupled manner, and a transmission controller identification signal (hereinafter referred to as NRS).
It is a modem that detects a signal and transmits / receives data according to the line type. The no-ringing communication circuit 25 is put into operation in accordance with the detection of NRS, raises the impedance, and receives the ringing.

Reference numeral 26 is an off-hook detection circuit which judges whether or not the telephone receiver is placed and outputs an off-hook signal while the telephone receiver is picked up and outputs an on-hook signal when the telephone receiver is placed.

27 is connected in parallel to the telephone line,
This is a 16 Hz pole reversal detection circuit that detects the extreme voltage of the telephone line or a 16 Hz signal and notifies the computer.

Reference numeral 28 is a computer unit (hereinafter referred to as MPU). When the notification factor of the connected gas meter 1 and gas meter 2 occurs, the MPU 28 sends a notification indicating whether to send the notification data of at least the notification destination corresponding to the notification factor and the data of the number of the gas meter 1 or 2. When the notification destination cannot receive the notification data, the notification data creating means for setting the bit in the notification table set in advance is read by the bit in the notification table and set in the terminal calling circuit 22. A notification data re-transmission determining means for re-transmitting, a re-transmission number measuring means for activating and counting the number of re-transmissions of the previous notification data in the re-transmission counter with the re-transmission of the notification data,
When the count value reaches 11, the program includes a transmission stop determination means for stopping the transmission of the notification data to the notification destination.

The operation of the automatic notification device configured as described above will be described below. FIG. 4 is a flow chart for explaining the operation of the embodiment.

The MPU 28 determines whether or not a report factor has occurred (S401). For example, the notification factor is generated when the preset meter reading date and time is reached. Then, either the gas meter 1 or the gas meter 2 is selected (S403), and the report destination is selected (S405). In this example, the gas meter 2 is selected after the gas meter 1 is selected.

Next, the notification bit is set (S40).
7). The setting of the notification bit is to set a bit (also called a flag) in the notification table including the notification destination and the gas meter number as shown in Table 1.

[0038]

[Table 1] According to Table 1, the data of the gas meter 1 and the gas meter 2 are transmitted to the report destinations A to C.

Next, the notification table is read, and a telegram containing the telephone number of one report destination, the gas meter number, the report factor, etc. is created and the report is made (S409). This notification process determines whether the telephone is in use or an incoming call is being made, and the line waits for a while, but the line usage right has priority and the line is occupied by the terminal calling circuit. You will not be able to use your telephone while you are inside.

Next, it is judged whether or not the notification has been normally made (S411). If the notification is not normally made, the counter value of the retry count counter is read and the retry count is 1
It is determined whether or not it is once (S413).

The judgment as to whether or not the call has been normally made is that the call has been made to the callee, and the non-reception is that the call has not been received or the call has been cut off halfway.

Next, when it is determined that the number of retries has not reached 11, the retry counter is incremented by 1 (S415). Next, it is determined whether or not the waiting time for the retry has ended, and when the waiting time has ended, the control moves to step 409 to retransmit the previous data. In this process, when data is not normally received by the report destination, the data is retransmitted until the count value of the retry counter reaches 11.

If it is determined in step S417 that the retry standby has not ended, it is determined whether or not a new notification factor has occurred. If a new notification factor has occurred, the same notification factor as above is taken. The report bit set in step S417 is set in the report table (S417), and control is performed in step S417.
Move to.

If it is determined in step S413 that the number of retries has reached 11, the first notification bit of the notification table previously created is cleared (S429).
For example, the bit in the column A of Table 1 is cleared.

Then, it is judged whether or not there is another notification bit (S431), and if there is, a control is performed in step S40.
In step 9, the notification data corresponding to the notification bit in the next column of the notification table is created and transmitted.

That is, when the report bit is set for each report destination set in the report table, the retry is performed 11 times including the first time.

Further, when it is determined in step S411 that the report has been normally completed, the report bit of the report destination is cleared (S423), and whether the report bit of the meter 2 to the same report destination (center) exists in the report table. If there is, the control is moved to step S409, the data of the gas meter 2 is transmitted to the same report destination, and the above determination is made.

If it is determined that there is no report bit for reporting the data of the gas meter 2 to the same report destination, it is determined whether there is a report bit in another column of the report table (S427). Controls step S4
09, the electronic message corresponding to the notification bit in the next column of the notification table is created and transmitted. If not, control is passed to step S401, and it is determined whether or not there is a notification factor.

Next, the sequence processing of the flowchart of FIG. 4 will be described using a timing chart. In FIG. 5, it is assumed that the data of the gas meter 1 and the gas meter 2 are sent to the center A, which is the notification destination.

FIG. 5 is a timing chart when data of two gas meters is transmitted to the center A.

As shown in the figure, for example, when the set meter reading date and time is reached and the notification bits of the gas meter 1 and the gas meter 2 are set in A of the notification table by the above processing, the data A1 is first transmitted. If this transmission is, for example, not received (not normally completed) and the retry is received at the third time, the data A2 is transmitted next. At this time, if the center A fails to receive data for some reason, and the reception continues thereafter, the data A2 is set to 1
When the data is simply retransmitted as shown in steps S409 to S417 of FIG. 4 without being retransmitted once, since the counting is continued after the retransmission of the previous data, it is added to the number of times the previous data A1 is transmitted. Therefore, the retry is completed 12 times after the data A1 is transmitted (including the retry).

Therefore, even if the data of the gas meter 1 and the gas meter 2 are sent to the same report destination, it is not retried 11 times when it is retransmitted, so that the power consumption of the battery is suppressed.

Next, description will be given of the case where the report destinations are A, B and C. FIG. 6 is a timing chart when there are three authorized callees and all are not received. In this example, the gas meter 2 is the same as the gas meter 1, and therefore its explanation is omitted.

As shown in the figure, data A1 and data B1 are sent to center A, center B and center B with the steadiness of the first regular notification (when the notification data is sent to a normal report destination is called regular notification). And data C1 are transmitted. This transmission is also based on the setting of the notification bit in the notification table.

When none of the report destinations receives the data, the counter value for retry is updated and the data A
1, data B1 and data C1 are retried, and if no reception is received before, retry is performed 5 times (6 times including the first time).
Up to 2 times), and after 2 hours, the data A again
1, data B1 and data C1 are transmitted first (see FIG. 6).
A). Also at this time, when none of the report destinations receives, the counter value for retry is updated and the data A
1. Even if the data B1 and the data C1 are retried, if the data is still not received, when the data is simply retransmitted as shown in steps S409 to S417 of FIG. 4, the retransmission of the previous data is continuously counted. Therefore, it is added to the number of times when the previous data A1, data B1 and data C1 were sent out. Therefore, two times after the new transmission of data A1, data B1 and data C1 (including retries), 12 times Ends the retry.

Therefore, the data is sent to the three addressees,
When it is retransmitted, it will not retry 11 times, so
This will reduce battery power consumption.

Next, the case of sending data to the three spare centers a, b and c will be described. This spare center is provided in correspondence to the authorized callees, Center A, Center B, and Center C, and the fact that the authorized callees cannot receive the message due to some factors, This is important data, and is used when it is desired to be registered separately. Even when it is sent to this preliminary notification destination, the notification bit is set in the notification table of Table 1.

FIG. 7 is a timing chart when there are three legitimate call destinations and three spares and no reception is made. In this example, the gas meter 2 is the same as the gas meter 1, and therefore its explanation is omitted.

As shown in the figure, data A is sent to center A, center B and center B by the first regular notification.
1, data B1 and data C1 are transmitted. This transmission is also based on the setting of the notification bit in the notification table.

When none of the report destinations receives the data, the retry counter value is updated and the data A
1. Even if the data B1 and the data C1 are retried, if there is still no reception, the retries are performed up to 5 times (6 times including the first time) (a in FIG. 7), and there is a preliminary report destination. In this case, data a1, data a1 and data c1 are sent to center a, center b and center c in the first preliminary notification. This transmission is also based on the setting of the notification bit in the notification table.

When none of the preliminary notification destinations has received, even if the counter value for retry is updated and the data a1, the data b1 and the data c1 are retried, if they are still not received, The preliminary report destination is retried up to 5 times (6 times including the first time) (b in FIG. 7).

Next, after 2 hours, the data A is again legally formed.
1, the data B1 and the data C1 are first transmitted, and at this time, when none of the report destinations is received, the retry counter value is updated to update the data A1 and the data B1.
Even if the data C1 is retried and the reception is still unsuccessful (c in FIG. 7), when the data is simply retransmitted as shown in steps S409 to S417 of FIG.
Since the counting is continued after the retransmission of the previous data, the count is added to the number of times when the previous data A1, data B1 and data C1 were transmitted, so that the data A is newly added after 2 hours.
1, the retry is completed 12 times after the data B1 and the data C1 are transmitted (including the retry).

Similarly, with respect to the preliminary notification destination, after 2 hours, the data A1, the data B1 and the data C1 are properly transmitted again first, and at this time as well, when none of the notification destinations receives the data. Even if the retry counter value is updated and the data A1, the data B1, and the data C1 are retried, the retry is finished 12 times when no reception is made as before.

Therefore, data is sent to the six destinations,
When the data is retransmitted, each of them is not retried anew 11 times, so that the power consumption of the battery is suppressed.

Next, in the case of transmitting only to the regular report destination,
The case where the center A and the center B can receive the data by resending will be described.

FIG. 8 shows the case where two regular notifications are sent.
FIG. 7 is a timing chart when one is able to retransmit / receive.
As shown in the figure, data A1 and data B1 are sent to center A, center B and center B by the first regular notification.
And data C1 are transmitted.

When none of the report destinations has received, the retry counter value is updated and the data A1, data B1 and data C1 are retried at the first retransmission. At this time, for example, when the center A can receive,
Since the data A1 has been successfully received, it is assumed that the data A2 can also be received, and the data A2 is interrupted and transmitted, after which the data B1 and the data C1 are transmitted. That is, the data A1 and the data A2 were received in the first retransmission.

Next, second retransmission, third retransmission, third retransmission
If the data B1 and the data C1 are transmitted up to the fifth time and the center B can receive the data after the fifth retransmission, the data B2 is immediately transmitted.
To transmit the data C1 (a in FIG. 8). Then, for example, when the center C has not received the data as before, the data C1 is retried up to the 11th time, and thereafter, the data of the gas meter 1 and the gas meter 2 is transmitted to the center C by the following notification factor. It is not transmitted until it occurs (b in FIG. 8).

That is, the data of the gas meter 2 is continuously transmitted when the legitimate addressee is able to receive it, but even if the data is sent to the addressee who is unable to send despite retrying 11 times. Stop sending data because it is useless.

In the case where the preliminary notification destination can be received, the data of the gas meter 2 is continuously transmitted when the preliminary notification destination is received, but the transmission is impossible regardless of the retry of 11 times. The sending of data is stopped because it is wasteful to send to the report destination.

FIG. 9 is a timing chart when there are three legitimate call destinations and backups, and only the center C and the backup report destination c do not receive due to retransmission.

As shown in the figure, data A is sent to center A, center B and center B by the first regular notification.
1, data B1 and data C1 are transmitted. When none of the report destinations receives the data, the counter value for retry is updated, and the data A1 and the data B are transmitted in the first retransmission.
1 and data C1 are retried. At this time, for example, when the center A can receive the data, it means that the data A1 has been received. Therefore, it is assumed that the data A2 can also be received, and the data A2 is interrupted and transmitted.
Is sent. That is, the data A1 and the data A2 were received in the first retransmission.

Next, the second retransmission, the third retransmission, the retransmission 4
If Center B and Center C cannot receive until the first time,
The data B1 and the data C1 are retransmitted even in the fifth retransmission (a in FIG. 9).

Then, when it is set in the notification table that the notification destination also notifies the preliminary notification destinations b and c, the data b1 is transmitted to the preliminary notification destination b,
Assuming that the data b1 can be received for the first time, the data b2 is immediately interrupt-transmitted, and then the data c1 is transmitted. That is, the gas meters 1 and 2 for the preliminary notification destination b
Data has been sent.

Next, since the preliminary report destination c1 could not be received, the data c1 is retransmitted until it can be received (b in FIG. 9).

Then, after 2 hours, the data C1 is transmitted again to the center C which is the regular notification destination, and if there is no reception, the data C1 is retried up to 11 times, and thereafter, the preliminary notification destination c is transmitted. Similarly, the data c1 is transmitted, and thereafter, the data of the gas meter 1 and the gas meter 2 are not transmitted to the center C and the preliminary notification destination c until the next notification factor occurs (c in FIG. 9).

That is, when the preliminary notification destination is received, the data of the gas meter 2 is continuously transmitted also when the preliminary notification destination is received, but the transmission is impossible regardless of retrying 11 times. The data transmission is stopped because it is wasteful to send it to the report destination.

In the above embodiment, the transmission controller connected with a plurality of gas meters has been described, but it may be used for a transmission controller connected with another terminal.

[0079]

As described above, according to the automatic reporting method for connecting a plurality of terminals of the present invention, when a reporting factor occurs, the reporting data of a plurality of connected terminals are transmitted in order. If the recipient cannot receive the notification data, the alert data is retransmitted, and when the number reaches the predetermined value by adding to the number of times the previous alert data was sent to the recipient, the alert data is sent to the recipient. By disabling it, when the report destination cannot be received due to some reason, retransmission of communication data of the terminal to that communication destination will be stopped after that, power consumption will be reduced, and As described above, when the same notification destination is set, the number of retransmissions is added to the number of retransmissions of the previous terminal, and the transmission is stopped at the maximum number of retransmissions of one retransmission sequence. Can be reduced Effect is obtained that the consumption of Luo power is further reduced.

Further, since the number of times of retransmission can be reduced, the occupied time of the line can be reduced, so that the annoyance of the user's telephone use can be reduced.

In addition, in the automatic reporting apparatus to which a plurality of terminals are connected according to the present invention, when a reporting factor occurs, the reporting data of the plurality of connected terminals is created by the reporting data creating means and the reporting data transmitting means is used. When the notification destination cannot be received when it is sent, the notification data resend determination means resends the notification data, and the resend count measurement means adds it to the resend count of the previous notification data to the notification destination, and the predetermined value When the notification destination becomes unable to receive due to some reason, the transmission stop means stops sending the notification data to the notification destination. Since the data retransmission is stopped after that, the power consumption is reduced and the number of retransmissions is added to the number of retransmissions of the previous terminal at the same report destination as in the past. Kunode, since the transmission stops at the maximum number of retransmissions of the retransmission count of 1 a retransmission sequence has the effect is obtained that the power consumption is further reduced in because it reduces the number of retransmissions. Further, since the number of times of retransmission can be reduced, the occupied time of the line can be reduced, and the effect that the user's trouble of using the telephone can be reduced is also obtained.

Further, when the notification data is transmitted, since the notification data for one notification destination or the notification data for a plurality of notification destinations is transmitted at the time of transmission, there may be one or more notification destinations. Since communication is possible and the number of times of retransmission is reduced at the time of retransmission, it is possible to reduce the power consumption and the line occupation time.

Further, when the communication data corresponding to the terminal is received by the designated report destination, deleting the report data reduces the number of report data at the time of transmission, thereby reducing power consumption and the line. This has the effect of reducing the occupation time.
