Communication terminals called concentrators that collectively transmit data of a smart meter and a plurality of smart meters are arranged so as to cover all households in an area under the jurisdiction of an electric power company. Specifically, the number of communication terminals is 10,000 or more.

At present, time synchronization is performed by a clock server on the center side, and as a specific example, data is transmitted from all communication terminals simultaneously at the timing of 0 minutes and 30 minutes per hour. As a result, a large amount of data is transmitted in a short time, and congestion occurs in the WAN line at the center entrance and the data reception buffer on the server, which imposes pressure on the network bandwidth and the processing performance of the data integration server.

  Patent Document 1 discloses a communication system that includes a center server and a communication terminal device, and stores a table that defines correspondence between identification information of the communication terminal device and a time zone for receiving data from the communication terminal device. Yes. In this communication system, the key for distributing the time zone for receiving data is notified from the center server to the communication terminal device using the above table to avoid data congestion.

*** Explanation of operation ***
The communication method 510 of the communication terminal apparatus 100 and the communication process S100 of the communication program 520 according to the present embodiment will be described using FIG.
As illustrated in FIG. 3, the communication process S100 includes a number information calculation process S10, a delay time calculation process S20, and a data transmission process S30.

<Number information calculation processing S10>
In the number information calculation process S <b> 10, the number information calculation unit 110 calculates the number information 111 based on the terminal specific value 141.

In step S <b> 101, the number information calculation unit 110 reads the terminal specific value 141 and the terminal specific reference value 142 from the storage unit 140.
Here, the terminal unique value 141 is a value for identifying the own apparatus from the plurality of communication terminal apparatuses 10. Specifically, the terminal unique value is a value that is sequentially assigned to each of the plurality of communication terminal apparatuses 10. For example, when the communication system 500 includes 10,000 communication terminal apparatuses, each of the plurality of communication terminal apparatuses 10 is assigned a terminal eigenvalue from 1 to 10,000 in order. Alternatively, a terminal-specific reference value 142 may be set in advance, and a value that is sequentially given from the terminal-specific reference value 142 may be used. For example, when the terminal specific reference value 142 is 30000, terminal specific values from 30001 to 40000 are assigned in order.
In other words, the terminal specific value 141 is a value related to the number of produced communication terminal devices 10. The terminal unique value 141 may not be a value that is sequentially assigned as long as it can indicate a value related to the number of produced communication terminal devices 10.

In step S <b> 102, the number information calculation unit 110 calculates the number information 111 using the terminal specific value 141 and the terminal specific reference value 142. The number information 111 is used as a dispersion coefficient of the communication terminal device 100 in the plurality of communication terminal devices 10.
Specifically, the number information calculation unit 110 calculates the number information 111 by taking a logarithm with base 10 for the difference between the terminal specific value 141 and the terminal specific reference value 142. That is, the number information = INT (LOG ((terminal specific value−terminal specific reference value), 10).
The number information 111 represents the number of the plurality of communication terminal devices 10. Specifically, the number information 111 is a value representing the number of existing operating terminals represented by the terminal specific value 141 at the digit level. The digit level is synonymous with the fact that it is expressed by a multiplier level.
For example, a case will be described in which the terminal unique value 141 of the communication terminal apparatus 100 that is the own apparatus is 38500 and the terminal unique reference value 142 is 30000. At this time, the number information 111 is obtained by INT (LOG ((38500-30000), 10), and the number information 111 is 4. The fact that the terminal specific value 141 is 38500 means that the communication system 500 has at least 8500 units. This means that the communication terminal device is operating, and the communication terminal device 100 is distributed to the 4-digit level in the plurality of communication terminal devices 10. Further, when the terminal unique value 141 of the communication terminal device 100 is 30050, the number of units The information 111 is obtained by INT (LOG ((30050-30000), 10), and the number information 111 is 2. The terminal specific value 141 is 30050, which means that the communication system 500 has at least 50 communication terminal apparatuses. The communication terminal device 100 is distributed to the two-digit level in the plurality of communication terminal devices 10 Meant to be.
Thus, the number information 111 is used as a dispersion coefficient of the communication terminal device 100 in the plurality of communication terminal devices 10.
The number information calculation unit 110 stores the calculated number information 111 in the storage unit 140.

<Delay time calculation process S20>
In the delay time calculation process S <b> 20, the delay time calculation unit 120 calculates the delay time 121 from the set time 146 common to the plurality of communication terminal apparatuses 10 based on the terminal unique value 141 and the number information 111. Hereinafter, the delay time 121 may be referred to as t.

FIG. 4 is a diagram showing a method for calculating the delay time t according to the present embodiment.
As shown in FIG. 4, the delay time calculation unit 120 divides the terminal eigenvalue 141 by a division value 143 that represents the number of divisions of the maximum delay time tm that is the maximum value of the delay time t, and a remainder obtained by dividing d is calculated. The delay time calculation unit 120 acquires the first delay time t1 based on the calculated remainder d. In addition, the delay time calculation unit 120 acquires the second delay time t <b> 2 based on the number information 111. Then, the delay time calculation unit 120 calculates a value obtained by adding the first delay time t1 and the second delay time t2 as the delay time t.

Here, the set time 146 is a data transmission reference time serving as a reference for determining the data transmission time T for transmitting the transmission data 199 in the communication terminal apparatus 100 that is each of the plurality of communication terminal apparatuses 10. Hereinafter, the set time 146 may be referred to as T0. The set time T0 is a time common to the plurality of communication terminal devices 10. Specifically, the set time T0 is set to 0 minutes per hour or 30 minutes per hour. In the present embodiment, it is assumed that the set time T0 is 0 minutes per hour and 30 minutes per hour.
The delay time t is a delay time from the set time T0 that is set in common to the plurality of communication terminal apparatuses 10.
The division value 143 represents the number by which the delay maximum time tm, which is the maximum value of the delay time t, is divided. For example, when the set time T0 is 0 minutes per hour and 30 minutes per hour, the maximum delay time tm that is the maximum value of the delay time t is 30 minutes that is the interval between the two set times. The division value 143 is a number for dividing this 30 minutes. The division value 143 is represented by a natural number. This division value 143 is calculated in advance by the system designer from the number of the plurality of communication terminal apparatuses 10 included in the communication system 500 and the interval between the set times 146 (that is, the data transmission reference time). Note that the division value 143 is also referred to as a delay coefficient.

In step S <b> 103, the delay time calculation unit 120 reads the first delay information 144 and the second delay information 145 from the storage unit 140.
FIG. 5 is a diagram showing an example of the first delay information 144 according to the present embodiment. FIG. 6 is a diagram illustrating an example of the second delay information 145 according to the present embodiment.
The first delay information 144 is a table in which each value from 1 to the division value 143 is associated with a candidate for the first delay time t1.

Specifically, when the division value 143 is 10, in the first delay information 144, each value from 1 to 10 is associated with a candidate for the first delay time t1. In the present embodiment, the remainder d obtained by dividing the terminal unique value 141 by the division value 143 is associated with the candidate for the first delay time t1.
The first delay time t1 is a time from when the maximum delay time tm is divided into respective time zones by the division value 143 and from when the set time T0 starts to each time zone. In the following, each time zone is defined as a divided time zone R.
As shown in FIG. 4, when the maximum delay time tm is 30 minutes (1800 sec) and the division value 143 is 10, each division time zone R obtained by dividing the maximum delay time tm by the division value 143 is 180 sec. Therefore, 0 when the remainder d is 0, 180 when the remainder d is 1, 360 when the remainder d is 2, 540 when the remainder d is 3,..., 1620 when the remainder d is 9 It becomes. The candidates for the first delay time t1 are 0 or more and smaller than the value obtained by multiplying the maximum delay time tm by the division value 143 and the division value 143. In the specific example, the candidate for the first delay time t1 is 0 or more and smaller than the value (1800 sec) obtained by multiplying the value (180 sec) obtained by dividing 1800 sec, which is the maximum delay time tm, by 10 that is the division value 143 (180 sec). Become.

The second delay information 145 is a table in which each range of a plurality of ranges that the number information 111 can take is associated with a candidate for the second delay time t2. Here, the plurality of ranges that the number information 111 can take are 1 digit, 2 digits, 3 digits,..., 9 digits, as shown in FIG. The number information 111 is based on the terminal specific value 141, or the terminal specific value 141 and the terminal specific reference value 142, such that 1 digit is in the range of 1 to 9, 2 digits is in the range of 10 to 99, and 3 digits is in the range of 100 to 999. The range in which the identifier of the communication terminal device 100 to be obtained is included is shown.
In the second delay information 145, each of a plurality of ranges that the number information 111 can take is associated with the time in each divided time zone R obtained by dividing the maximum delay time tm by the divided value 143. For example, as shown in FIG. 6, when each divided time zone R obtained by dividing the maximum delay time tm by the divided value 143 is 180 seconds, 90 seconds for one digit, 45 seconds for two digits, and 22 for three digits. .5 sec. Therefore, the candidate for the second delay time t2 is 0 or more and smaller than the value obtained by dividing the maximum delay time tm by the division value 143. Specifically, the candidate for the second delay time t2 is equal to or greater than 0 and smaller than 180 sec, which is obtained by dividing 1800 sec of the maximum delay time tm by 10 that is the division value 143.

  As described above, in the first delay information 144, the maximum delay time tm is divided equally by the division value 143, and the time from the set time T0 to the start of each divided time zone R is set. In the second delay information 145, the time for dispersing the communication terminal apparatus 100 in each divided time zone R is set using the number information 111 as a dispersion coefficient.

  In step S <b> 104, the delay time calculation unit 120 acquires a remainder d obtained by dividing the terminal specific value 141 by the division value 143. Based on the first delay information 144, the delay time calculation unit 120 acquires a candidate for the first delay time t1 corresponding to the remainder d as the first delay time t1. Specifically, when the terminal specific value 141 is 30103, the remainder d obtained by dividing 30103 by 10 which is the division value 143 is 3. The delay time calculation unit 120 refers to the first delay information 144 and determines 540 sec corresponding to the remainder 3 as the first delay time t1.

  In step S105, the delay time calculation unit 120 acquires the second delay time t2 corresponding to the number information 111 calculated in step S102 from the second delay information 145. Based on the second delay information 145, the delay time calculation unit 120 acquires a candidate for the second delay time t2 corresponding to the number information 111 as the second delay time t2. Specifically, when the terminal specific value 141 is 30103, the number information 111 is calculated as three digits in step S102. The delay time calculation unit 120 refers to the second delay information 145 and acquires 45 seconds corresponding to three digits as the second delay time t2.

  In step S106, the delay time calculation unit 120 calculates a result obtained by adding the first delay time t1 and the second delay time t2 as the delay time t.

  The above-described number information calculation process S10 and delay time calculation process S20 are executed immediately after the communication program 520 of the communication terminal apparatus 100 is started, and the delay time 121 is stored in the storage unit 140.

<Data transmission process S30>
In the data transmission process S30, the data transmission unit 130 transmits the transmission data 199 at a time obtained by adding the delay time t to the set time T0.
In step S107, the data transmission unit 130 determines whether or not the set time T0 is present. Specifically, the data transmission unit 130 determines whether it is 0 minutes per hour or 30 minutes per hour. If the data transmission unit 130 determines that it is not the set time T0, it repeats Step S107 until the set time T0 is reached. If the data transmission unit 130 determines that the set time T0 is reached, the process proceeds to step S108.
In step S108, the data transmission unit 130 waits for a delay time t from the set time T0.
In step S108, the data transmission unit 130 transmits the transmission data 199.

As a specific example, a case where the terminal specific value 141 is 30103, the division value 143 is 10, and the set time is 0 minutes per hour and 30 minutes per hour will be described with reference to FIG.
As described above, in this specific example, the remainder d is 3. Therefore, the first delay time t1 is 540 sec. The number information 111 is three digits, and the second delay time t2 is 45 seconds. Therefore, the delay time t is 585 sec.
When the data transmission unit 130 determines that the set time (here, 00:00) is reached, the data transmission time 199 is set at the time 09:45 585 sec after the set time (00:00) as the data transmission time T. Send.

*** Other configurations ***
In the present embodiment, in the second delay information 145, for example, in the case of the communication terminal apparatus 100 at the two-digit level, in the case of the communication terminal apparatus 100 at the three-digit level, 90 sec that is 1/2 of each divided time zone R. The second delay time t2 was set to ½ of the previous number of digits as the number of digits increased, such as 45 seconds, which is ¼ of the divided time zone R. Therefore, the communication terminal devices are distributed in the first half of each divided time zone R. However, the terminal eigenvalue of the same digit level is further divided into two, the first terminal eigenvalue is distributed in the first half time zone of each divided time zone R, and the second half terminal eigenvalue is in the second half time zone of each divided time zone R. It may be dispersed. By performing such processing, it is possible to more reliably distribute the transmission timing.

In the present embodiment, the function of communication terminal apparatus 100 is realized by software, but as a modification, the function of communication terminal apparatus 100 may be realized by hardware.

Specifically, the processing circuit 909 includes a single circuit, a composite circuit, a programmed processor, a parallel programmed processor, a logic IC, a GA (Gate Array), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field). -Programmable Gate Array).

  The function of the “unit” of the communication terminal apparatus 100 and the storage unit 140 may be realized by one processing circuit 909 or may include one or more processing circuits similar to the processing circuit 909 described above. The function of “unit” may be realized by being distributed between the processing circuit 909 and other processing circuits.

  As another modification, the function of the communication terminal device 100 may be realized by a combination of software and hardware. That is, some functions of the communication terminal device 100 may be realized by dedicated hardware, and the remaining functions may be realized by software.
