Detailed Description
The embodiments are described with reference to the drawings. In the drawings, the same or corresponding portions are denoted by the same reference numerals. Repeated description of this portion is appropriately simplified or omitted.
Embodiment 1.
Fig. 1 is a configuration diagram of a communication system in embodiment 1.
In fig. 1, a plurality of communication terminal apparatuses 1 are respectively installed in a building to be monitored. The center apparatus 2 is provided in a management center that manages a building to be monitored. The communication network 3 is connected to a plurality of communication terminal apparatuses 1 and a center apparatus 2.
The plurality of communication terminal apparatuses 1 monitor abnormality of equipment of the building, respectively. When detecting an abnormality of the device or the like, each of the plurality of communication terminals notifies the abnormality via the communication network 3.
In the management center, when the center apparatus 2 receives notification of abnormality or the like of the equipment, an operator dispatches maintenance personnel of the equipment to the building. When the program needs to be updated for the plurality of communication terminal apparatuses 1, the operator operates the center apparatus 2 so that data of the program for update is transmitted as target data to the communication terminal apparatus 1 to be subjected.
For example, the center device 2 includes a storage unit 2a, a communication control unit 2b, a traffic calculation unit 2c, an input/output control unit 2d, and a traffic monitoring unit 2e.
The storage section 2a is provided to be capable of storing data.
The communication control unit 2b is provided so as to be capable of communicating with a plurality of communication terminal apparatuses 1. For example, the communication control unit 2b stores the abnormal data in the storage unit 2a each time the abnormal data is received from the communication terminal apparatus 1.
The traffic volume calculating unit 2c calculates the traffic volume of the abnormal data, based on the abnormal data, by specifying the communication terminal device 1. The traffic calculation unit 2c associates the identification data of the communication terminal device 1 with the traffic data of the abnormal data and stores the data as the calculation result in the storage unit 2a.
The input/output control unit 2d monitors the storage unit 2a. When the abnormality data is stored in the storage unit 2a, the input/output control unit 2d notifies the operator of an abnormality corresponding to the abnormality data by performing display control, audio control, or the like corresponding to the content of the abnormality data.
The input/output control unit 2d stores data of a "traffic threshold" indicating a traffic volume of the communication network 3 that can be used for a "preset period" without additional cost in the storage unit 2a by an operation of an operator. When the program needs to be updated for the plurality of communication terminal apparatuses 1, the input/output control unit 2d sets the data of the program for update as the target data by the operation of the operator. The input/output control unit 2d associates the target data with data indicating the size of the target data and stores the data in the storage unit 2a.
The traffic monitoring unit 2e obtains various data from the storage unit 2a. The traffic monitoring unit 2e determines whether or not the transmission of the target data to the plurality of communication terminal apparatuses 1 is necessary at a predetermined timing. When it is necessary to transmit target data to a plurality of communication apparatuses, the traffic monitoring unit 2e determines past reception amounts in the determination period for the plurality of communication terminal apparatuses 1, respectively, based on the data stored in the storage unit 2a. The traffic monitoring unit 2e selects the communication terminal apparatus 1 from the plurality of communication terminal apparatuses 1 in order of increasing past reception amounts in the determination period. The traffic monitoring unit 2e causes the communication control unit 2b to transmit the target data to the selected communication terminal device 1.
Next, management of transmission of object data will be described with reference to fig. 2.
Fig. 2 is a database stored in the center device of the communication system in embodiment 1.
As shown in fig. 2, the storage unit 2a stores data such as "communication terminal apparatus", "traffic used for notification of abnormality", "use frequency order", and "transmission completion".
The "communication terminal apparatus" is identification data of the communication terminal apparatus 1.
The "traffic volume used for the abnormality notification" is data indicating the volume of the abnormal data transmitted by the communication terminal apparatus 1. "4 months" is data indicating the amount of abnormal data transmitted in 4 months. "5 months" is data indicating the amount of abnormal data transmitted in 5 months. "average" is data representing an average of "4 months" and "5 months".
For example, in the communication terminal apparatus 1 of "No1", the "4 months" is "10". "5 months" is "40". The "average" is "25". For example, in the communication terminal apparatus 1 of "No2", the "4 months" is "10". "5 months" is "20". The "average" is "15". For example, in the communication terminal apparatus 1 of "No3", the "4 months" is "20". "5 months" is "20". The "average" is "20". For example, in the communication terminal apparatus 1 of "No4", the "4 months" is "20". "5 months" is "10". The "average" is "15".
For example, in the communication terminal apparatus 1 of "No5", the "4 months" is "30". "5 months" is "30". The "average" is "30". For example, in the communication terminal apparatus 1 of "No6", the "4 months" is "30". "5 months" is "50". The "average" is "40". For example, in the communication terminal apparatus 1 of "No7", the "4 months" is "40". "5 months" is "20". The "average" is "30". For example, in the communication terminal apparatus 1 of "No8", the "4 months" is "40". "5 months" is "10". The "average" is "25".
The "use frequency order" is data indicating priority order given in order from large to small as "average" of use frequency.
For example, in the communication terminal apparatus 1 of "No1", the "frequency of use order" is "3". For example, in the communication terminal apparatus 1 of "No2", the "frequency of use order" is "5". For example, in the communication terminal apparatus 1 of "No3", the "frequency of use order" is "4". For example, in the communication terminal apparatus 1 of "No4", the "frequency of use order" is "5".
For example, in the communication terminal apparatus 1 of "No5", the "frequency of use order" is "2". For example, in the communication terminal apparatus 1 of "No6", the "frequency of use order" is "1". For example, in the communication terminal apparatus 1 of "No7", the "frequency of use order" is "2". For example, in the communication terminal apparatus 1 of "No8", the "frequency of use order" is "3".
The "transmission completed" is identification data indicating whether or not the transmission of the object data to the communication terminal apparatus 1 has been completed.
For example, in the communication terminal apparatus 1 of "No1", the "transmission completion" is "completion". For example, in the communication terminal apparatus 1 of "No2", the "transmission completed" is empty. For example, in the communication terminal apparatus 1 of "No3", the "transmission completion" is "completion". For example, in the communication terminal apparatus 1 of "No4", the "transmission completed" is empty.
For example, in the communication terminal apparatus 1 of "No5", the "transmission completion" is "completion". For example, in the communication terminal apparatus 1 of "No6", the "transmission completion" is "completion". For example, in the communication terminal apparatus 1 of "No7", the "transmission completion" is "completion". For example, in the communication terminal apparatus 1 of "No8", the "transmission completion" is "completion".
The "predetermined period" is "1 month" with respect to the traffic volume of the communication network 3 that can be used without additional cost. The "traffic threshold" is "1000". The size of the object data is "150".
The traffic monitoring unit 2e calculates "1000"/"150". "1000"/"150" is greater than 6 and less than 7. In this case, the traffic monitoring unit 2e sets the number of communication terminal apparatuses 1 capable of transmitting the target data to 6.
The traffic monitoring unit 2e selects 6 communication terminal apparatuses 1 in the order of decreasing "frequency of use". Specifically, the traffic monitoring unit 2e selects 6 communication terminal apparatuses 1 in the order of "No6", "No5", "No7", "No1", "No8", and "No 3".
The traffic monitoring unit 2e causes the communication control unit 2b to transmit the target data to the communication terminal apparatuses 1 of "No6", "No5", "No7", "No1", "No8", "No 3".
The traffic monitoring unit 2e causes the storage unit 2a to store "completed" in "transmission completed" of the communication terminal apparatuses 1 of "No6", "No5", "No7", "No1", "No8", "No 3".
At the timing of the next month, the traffic monitoring unit 2e selects the communication terminal apparatuses 1 from among the communication terminal apparatuses 1 for which "transmission is completed" in order of "frequency of use" from the order of decreasing to increasing. Specifically, the traffic monitoring unit 2e selects the communication terminal apparatuses 1 of "No2" and "No 4".
The traffic monitoring unit 2e causes the communication control unit 2b to transmit the target data to the communication terminal apparatuses 1 of "No2" and "No 4".
The traffic monitoring unit 2e causes the storage unit 2a to store "completed" in "completed transmission" of the communication terminal apparatus 1 of "No2" or "No 4".
Next, the operation of the center device 2 will be described with reference to fig. 3 and 4.
Fig. 3 and 4 are flowcharts for explaining the operation of the center device of the communication system in embodiment 1.
In step S1, the center apparatus 2 determines whether or not it is necessary to transmit target data to a plurality of communication apparatuses.
When there is no need to transmit the target data to the plurality of communication apparatuses in step S1, the center apparatus 2 ends the operation.
When it is necessary to transmit the target data to the plurality of communication apparatuses in step S1, the center apparatus 2 performs the operation of step S2. In step S2, the center device 2 calculates the frequency of use of each of the plurality of communication terminal devices 1 from the "traffic volume used for the abnormality notification" of each of the plurality of communication terminal devices 1.
After that, the center apparatus 2 performs the operation of step S3. In step S3, the center device 2 calculates the number of communication terminals capable of transmitting the target data without additional cost in a predetermined period based on the "traffic threshold" and the size of the target data. After that, the center apparatus 2 performs the operation of step S4. In step S4, the center device 2 determines whether or not the processing for all the communication terminal devices 1 is completed.
If the processing for any communication terminal apparatus 1 is not completed in step S4, the center apparatus 2 performs the operation of step S5. In step S5, the center device 2 determines whether or not the transmission of the target data to the communication terminal device 1 having the highest frequency of use among the communication terminal devices 1 whose processing has not been completed.
If the transmission of the target data to the communication terminal apparatus 1 is not completed in step S5, the center apparatus 2 performs the operation of step S6. In step S6, the center apparatus 2 selects the communication terminal apparatus 1 as the "transmission destination communication terminal apparatus".
After that, the center apparatus 2 performs the operation of step S7. In step S7, the center device 2 reduces the number of communication terminal devices 1 capable of transmitting the target data by 1. After that, the center apparatus 2 performs the operation of step S8. In step S8, the center device 2 determines whether or not the number of communication terminal devices 1 capable of transmitting the target data is 0.
When the communication terminal device 1 has transmitted the target data in step S5 or when the number of communication terminal devices 1 capable of transmitting the target data in step S8 is not 0, the center device 2 performs the operation in step S9. In step S9, the center apparatus 2 selects the communication terminal apparatus 1 having the second highest frequency of use among the communication terminal apparatuses 1 whose processing has not been completed.
When the number of communication terminal apparatuses 1 capable of transmitting the target data is 0 in step S8, the center apparatus 2 performs the operation of step S10. In step S10, the center apparatus 2 transmits the target data to the communication terminal apparatus 1 selected as the "transmission destination communication terminal apparatus". After that, the center apparatus 2 performs the operation of step S11. In step S11, the center device 2 stores the identification data of the communication terminal device 1 that transmitted the object data. After that, the center apparatus 2 ends the operation.
When the processing for all the communication terminal apparatuses 1 ends in step S4, the center apparatus 2 performs the operation of step S12. In step S12, the center apparatus 2 determines whether or not the communication terminal apparatus 1 selected as the "transmission destination communication terminal apparatus" exists.
If the communication terminal device 1 selected as the "transmission destination communication terminal device" does not exist in step S12, the center device 2 ends the operation.
When the communication terminal device 1 selected as the "transmission destination communication terminal device" exists in step S12, the center device 2 ends the operation after performing the operations of step S10 and step S11.
According to embodiment 1 described above, the center device 2 selects the communication terminal device 1 from the plurality of communication terminal devices 1 in order of increasing past reception amounts in the determination period, and transmits the target data. Therefore, efficient communication control can be performed for the plurality of communication terminal apparatuses 1.
The center device 2 selects the communication terminal device 1 so that the traffic amount when the target data is transmitted does not exceed a predetermined amount. Therefore, even when there is a restriction in the traffic, it is possible to perform efficient communication control for the plurality of communication terminal apparatuses 1.
