Hereinafter, a detailed configuration of the platform server 300 according to the first embodiment of the present invention will be described with reference to FIG. 2.

Platform server 300 according to the present invention, the data receiving unit 310 for receiving the sensed data collected according to the operation of the application operating in the information collection environment from the at least one information collection terminal 100 and the received detection It is determined that there is an overload time point at which a data transmission unit 320 for transmitting data to at least one collection server 500 designated as a reception destination and an overload reception of detection data received from at least one information collection terminal 100 occur. Information for providing transmission control information for adjusting at least one of a transmission period for transmitting the sensed data and a transmission time point within the transmission period to the at least one information collecting terminal 100 according to a predefined transmission control policy. The collection terminal control unit 330 is included.

The data receiver 310 receives, from at least one information acquisition terminal 100, the sensed data sensed at a remote location according to the driving of an application operating in the information collection environment.

More specifically, the data receiver 310 detects the sensed data sensed at a remote location according to the operation of an application operating in an information gathering environment such as low / high speed data communication, remote meter reading, weather information, location tracking, and remote control. It receives from the information collecting terminal 100.

Here, the reception of the sensed data is carried out using an Async method and a Short Message Service (SMS) method using Code Division Multiple Access (CDMA), a Short Message Service (SMS) method using Wideband CDMA (WCDMA), and an Unstructured USSD. Supplementary Service Data) or various supported communication methods such as Wi-Fi, Wibro, and Wired.

The data transfer unit 320 transmits the received sensing data to one or more collection servers 500 designated as destinations. More specifically, the data transmitter 320 transmits the sensed data received from the information collecting terminal 100 to one or more collecting servers 500 designated as destinations based on previously stored destination information.

In this case, the data transmission unit 320 buffers / stores the sensed data and provides the collected data to the collection server 500 according to a request from at least one collection server 500 designated as a destination, or without a separate buffering / storing process. The authenticated detection data may be provided to one or more collection servers 500 designated as destinations in real time.

If it is determined that there is an overload time point at which the reception overload of the sensing data received from the at least one information collection terminal 100 occurs, the information collection terminal control unit 330 corresponds to at least one corresponding to the predefined transmission control policy. It provides the transmission control information to adjust at least one of the transmission period and the transmission time point within the transmission period for transmitting the sensed data to the information collection terminal (100).

In more detail, the information collecting terminal control unit 330 may receive excessive load due to the sensing data received from the at least one information collecting terminal 100 based on the preset sensing data transmission period information for each information collecting service. It is determined whether there is an overload point occurring.

That is, the platform server 300, in particular, the information collection terminal controller 330 recognizes / stores the preset sensing data transmission period information for each information collection service. For example, the detection data transmission cycle information for each information collection service may include a data transmission cycle of 1 minute in response to the weather information providing information collection service, and a data transmission cycle of 10 minutes in response to the meter reading information providing information collection service. Can be.

In addition, the information collecting terminal controller 330 recognizes the information collecting terminal identification information and the information collecting service identification information in the sensed data from the at least one information collecting terminal 100 received through the data receiving unit 310. From the information collecting terminal, it is possible to determine what information collection service is received.

Accordingly, the information collecting terminal controller 330 recognizes how many information collecting terminals 100 sensed data according to information collecting service is received, and based on the detected data transmission period information for each information collecting service, the information collecting service. Since the transmission period corresponding to the transmission period can be recognized, it is possible to determine whether there is an overload time point at which the reception overload occurs based on the sensed data received based on these data. In this case, the load reference, which is a criterion for determining that a reception overload occurs, may be a preset value that is automatically calculated by the platform server 300 operator or by an algorithm for calculating the load reference.

Accordingly, if it is determined that there is an overload time point at which the reception overload of the sensed data to be received occurs, the information collection terminal control unit 330 detects the at least one information collection terminal 100 according to the transmission control policy. Transmission control information for adjusting at least one of a transmission period for transmitting data and a transmission time point in the transmission period may be provided.

Here, the transmission control policy is a transmission time point in the transmission cycle to each information collection terminal belonging to the information collection terminal group when the overload time point exists due to the sensing data received from the information collection terminal group corresponding to a predetermined information collection service. A plurality of pieces of information gathering when the overload point exists due to a transmission time control scheme for providing the transmission control information and sensed data received from a plurality of groups of information gathering terminals corresponding to a plurality of information gathering services. The terminal may include at least one of the transmission period control method for providing the transmission control information to adjust the transmission period to at least one information collection terminal group of the group.

In other words, the transmission control policy, when there is an overload time due to the detection data received from the information collection terminal group corresponding to a predetermined information collection service (for example, weather information providing information collection service), the information collection terminal group, that is, the weather Information Provision A transmission point control method that provides transmission control information for adjusting the transmission point within a corresponding transmission period (eg, 1 minute) may be adopted for each information collection terminal that provides sensing data according to the information collection service.

In addition, the transmission control policy includes a plurality of information collection terminals corresponding to a plurality of information collection services, for example, a first information collection terminal group for providing sensing data according to a weather information providing information collection service, and meter reading information providing information collection. When there is an overload point due to the sensing data received from the second information collecting terminal group providing the sensing data according to the service, the first and second information collecting terminals correspond to at least one information collecting terminal group among the plurality of first and second information collecting terminals. A transmission period control method for providing transmission control information for adjusting the transmission period may be adopted.

Thus, the case of using the transmission time control method of the transmission control policy, the information collection terminal control unit 330 is received from the information collection terminal group corresponding to the information collection service (eg, weather information providing information collection service). If it is determined that there is an overload time at which reception overload occurs based on the sensed data, the information collection terminal according to the transmission time control method of the transmission control policy, that is, each information collection providing the detection data according to the weather information providing information collection service. The terminal 100 may provide transmission control information for adjusting a transmission time point in a corresponding transmission period (eg, 1 minute).

At this time, the information collection terminal control unit 330, the transmission control to adjust the transmission time in the corresponding transmission period (for example 1 minute) to each information collection terminal 100 for providing the detection data according to the weather information providing information collection service In providing the information, at least one transmission time (eg, first transmission time 00 seconds, second transmission time 05 seconds, third transmission time 10 seconds, etc.) within a transmission period (eg, 1 minute) according to a transmission time control method. ) Is randomly generated, and randomly selects one transmission time point among the generated transmission time points corresponding to each information collecting terminal 100 according to the transmission time control method, and instructs to adjust the transmission time accordingly. Transmission control information can be provided.

Meanwhile, referring to the case in which the transmission period control method of the transmission control policy is used, the information collecting terminal controller 330 may be configured to provide first information for providing sensing data according to a plurality of information collecting services, for example, weather information providing information collecting service. According to the transmission cycle control method of the transmission control policy, if it is determined that there is an overload point by the detection data received from the second information collection terminal group providing the detection data according to the collection terminal and the meter reading information providing service. The first information collecting terminal group and the second information collecting terminal group may provide transmission control information for adjusting the transmission period to at least one information collecting terminal group.

That is, the information collecting terminal controller 330 provides weather information to the information collecting terminals 100 belonging to the first information collecting terminal group that provides the sensing data according to the weather information providing information collecting service, according to the transmission cycle control scheme. Providing transmission control information (e.g., adjusting the transmission period 1 minute and 30 seconds) to change the transmission period by adjusting the corresponding transmission period (for example, 1 minute) according to the information collection service, and detecting according to the information collection service providing meter reading information Transmission control information for changing the transmission period by adjusting the transmission period (for example, 10 minutes) according to the meter reading information providing information collection service to the information collection terminals 100 belonging to the second information collection terminal group that provides data ( Example: Adjust to 11 minutes of transmission period).

In this case, when the information collecting terminal control unit 330 provides the transmission control information to adjust the transmission period corresponding to the specific information collection service according to the transmission period control method, the information collection service information of the sensed data for each information collection service described above. It may be desirable to store / manage the transmission data by adjusting the transmission period by providing transmission control information, such as the adjusted transmission period, in the sensed data transmission period information of the corresponding information collection service.

On the other hand, the information collection terminal control unit 330, after providing the transmission control information to adjust at least one of the transmission period and the transmission time in the transmission period to the at least one information collection terminal 100 based on the transmission control policy When it reaches the preset control period, it is determined whether there is an overload time at which a reception overload occurs based on the sensed data received from the information collecting terminal 100 in the present state as described above. Based on the transmission control policy, we will repeat the process of providing transmission control information.

Thereafter, the data transmission unit 120 adjusts the detection data collected by the detection data collection unit 110 to the platform server 300 every transmission period (for example, 1 minute), rather than 00 seconds per minute. Will be sent at the time of transmission.

In addition, the information collection terminal 100 provides the meter reading information providing information collection service, providing sensing data to the platform server 300 according to the transmission period of 10 minutes, the transmission period from the platform server 300 11 minutes When the transmission control information commanding the adjustment is received, the data transmission unit 120 adjusts the transmission period from 10 minutes to 11 minutes according to the transmission control information.
