Description

The present invention relates to a sensing data collection method and a sensing data collection system, and more particularly to a sensing data collection method and a sensing data collection system that communicate with a fixed gateway device or a mobile gateway device.

With the rapid development of science and technology, various household and personal sensors have also become integrated with the Internet of Things (IoT) and smart home appliances. These sensors have a network connection function and transmit sensor sensing data to a host terminal via the network for analysis. Those skilled in the art can grasp information on various physical quantities of a specific building or a specific area based on the analysis results.

Although sensors have the ability to connect to the Internet, most current sensors still need to rely on transfer devices to transmit information on various physical quantities to a host terminal. The transfer device may be an access point, a gateway device, or the like. However, an access point or gateway device is not necessarily within the communication range of the sensor. If there is no access point or gateway device within the communication range of the sensor, current sensors cannot automatically transmit information on various physical quantities to the host terminal. Therefore, the host terminal cannot automatically complete data collection.

Therefore, developing automated sensing data collection methods that are highly convenient and reliable is an important design challenge.

FIG. 1 is a configuration diagram of an embodiment of a sensing data collection system 100 of the present invention. The sensing data collection system 100 includes sensors 10a, 11a, 12a, at least one gateway device 10b, 11b, 14, and a server 15. A sensor senses a physical quantity. The sensor may be any type of sensor. For example, in FIG. 1, the sensor 10a may be a gas meter within the building 10. The sensor 11a may be an electricity meter within the building 11. Sensor 12a may be a thermometer within building 12. At least one Gateway device is connected to and communicates with the sensor. For example, in FIG. 1, a sensor 10a in a building 10 can communicate with a gateway device 10b. The sensor 11a inside the building 11 can communicate with the gateway device 11b. The sensor 12a inside the building 12 can communicate with the gateway device 14 carried by the person 13. In the sensing data collection system 100, the gateway device may be a fixed gateway device or a mobile gateway device. For example, the gateway device 10b in the building 10 and the gateway device 11b in the building 11 are fixed gateway devices. It is a gateway device. The gateway device 14 carried by the person 13 is a mobile gateway device. Additionally, the mobile gateway device may be a wearable gateway device or a vehicle-mounted gateway device. All reasonable technical modifications to the invention are intended to fall within the scope of its disclosure. The server 15 is connected to at least one gateway device. For example, in FIG. 1, the server 15 is connected to the gateway device 10a, the gateway device 11a, and the gateway device 14. The present invention does not limit the connection method and communication protocol between the sensor and the gateway device. The present invention also does not limit the connection method and communication protocol between the gateway device and the server. In the sensing data collection system 100, after the sensor detects at least one gateway device within communication range, the sensor selectively collects the collected data sensed by the sensor based on the mobility of the at least one gateway device. The information may be transmitted to the first gateway device or the second gateway device among the two gateway devices. Here, the first gateway device is defined as a fixed gateway device (for example, the gateway device 10b in the building 10 and the gateway device 11b in the building 11). The second gateway device is defined as a mobile gateway device (for example, a gateway device 14 carried by a person 13). The first gateway device or the second gateway device may transmit the collected data to the server 15 after receiving the collected data sensed by the sensor. For the sake of brevity, the first gateway device will hereinafter be referred to as the first gateway device 11a. The second gateway device will hereinafter be referred to as a second gateway device 14. In addition, in the sensing data collection system 100, if the sensor cannot detect a fixed gateway device within the communication range, the sensor may transmit the collected data to the mobile gateway device. For example, the sensor 12a can communicate with a gateway device within its communication range using LoRa (Long Range) wireless communication technology. If sensor 12a does not discover a fixed gateway device within communication range, sensor 12a transmits the collected data to a mobile gateway device (eg, second gateway device 14) within communication range. The sensing data collection system 100 implements an automated, highly convenient and reliable sensing data collection method, the details of which are as follows.

FIG. 2 is a flowchart of the communication mode between the sensor 11a and the first gateway device 11b in the sensing data collection system 100. The flowchart of the communication mode between the sensor 11a and the first gateway device 11b includes steps S201 to S204. It is assumed that all reasonable technical changes from step S201 to step S204 fall within the scope of the disclosure of the present invention. Steps S201 to S204 are as follows.

ステップＳ２０１において、センサ１１ａはセンシングデータの収集を開始する。例えば、各種物理量の収集を開始する。ステップＳ２０２において、センサ１１ａは、その通信範囲内に第１ゲートウェイ装置１１ｂ（固定式ゲートウェイ装置）が存在するか否かを検出してもよい。ステップＳ２０３において、センサ１１ａの通信範囲内に第１ゲートウェイ装置１１ｂが検出された場合、センサ１１ａは収集データを第１ゲートウェイ装置１１ｂに伝送してもよい。一方、ステップＳ２０４において、センサ１１ａの通信範囲内に第１ゲートウェイ装置１１ｂが検出されなかった場合、センサ１１ａは収集データをキュ形式でキャッシング（Ｃａｃｈｉｎｇ）してもよい。例えば、センサ１１ａは内蔵メモリを有し、収集データを先入先出（Ｆｉｒｓｔ Ｉｎ Ｆｉｒｓｔ Ｏｕｔ，ＦＩＦＯ）の方式で、キュ形式でそのメモリにキャッシングしてもよい。

In step S201, the sensor 11a starts collecting sensing data. For example, start collecting various physical quantities. In step S202, the sensor 11a may detect whether the first gateway device 11b (fixed gateway device) is present within its communication range. In step S203, if the first gateway device 11b is detected within the communication range of the sensor 11a, the sensor 11a may transmit the collected data to the first gateway device 11b. On the other hand, in step S204, if the first gateway device 11b is not detected within the communication range of the sensor 11a, the sensor 11a may cache the collected data in a queue format. For example, the sensor 11a may have a built-in memory, and the collected data may be cached therein in a queue format on a first-in-first-out (FIFO) basis.

FIG. 3 is a flowchart of the communication mode between the sensor 12a and the second gateway device 14 in the sensing data collection system 100. The flowchart of the communication mode between the sensor 12a and the second gateway device 14 includes steps S301 to S304. It is assumed that all reasonable technical changes from step S301 to step S304 fall within the scope of the disclosure of the present invention. Steps S301 to S304 are as follows.

ステップＳ３０１において、サーバ１５はセンサ１２ａへの設定情報を生成し、センサ１２ａを制御して第２ゲートウェイ装置１４の到達時間を予め設定させてもよい。例えば、センサ１２ａは、予め第２ゲートウェイ装置１４の到達時間を７：００ＡＭに設定して、センサ１２ａが到達時間（例えば７：００ＡＭ）になれば第２ゲートウェイ装置１４を検出する。ステップＳ３０２において、センサ１２ａはその通信範囲内の第２ゲートウェイ装置１４（移動式ゲートウェイ装置）の存在性を検出してもよい。ステップＳ３０３において、第２ゲートウェイ装置１４がセンサ１２ａの通信範囲内に存在する場合、センサ１２ａはキュ形式でキャッシングされた収集データを第２ゲートウェイ装置１２ａに伝送する。一方、ステップＳ３０４において、第２ゲートウェイ装置１４がセンサ１２ａの通信範囲内に存在しない場合、センサ１２ａは即時の収集データをキュ形式でキャッシングし続け（例えば、前記のＦＩＦＯ方式であるが、これに限定されない）、かつ、検出時間帯内（例えば、７：００ＡＭ～８：００ＡＭ）にセンサ１２ａの通信範囲内の第２ゲートウェイ装置１４の存在性を検出し続ける。前記の通り、ステップＳ３０１からステップＳ３０４に対し任意に合理的な技術変更を行うこと可能である。例えば、一実施例において、センサ１２ａが検出時間帯（例えば、７：００ＡＭ～８：００ＡＭ）内にも以前として第２ゲートウェイ装置１２ａを検出できなかった場合、エネルギー消費を節約するために、センサ１２ａの検出機能を遮断してもよい。

In step S301, the server 15 may generate setting information for the sensor 12a, and control the sensor 12a to preset the arrival time of the second gateway device 14. For example, the sensor 12a sets the arrival time of the second gateway device 14 to 7:00 AM in advance, and detects the second gateway device 14 when the arrival time of the sensor 12a reaches the arrival time (for example, 7:00 AM). In step S302, the sensor 12a may detect the presence of the second gateway device 14 (mobile gateway device) within its communication range. In step S303, if the second gateway device 14 exists within the communication range of the sensor 12a, the sensor 12a transmits the collected data cached in queue format to the second gateway device 12a. On the other hand, in step S304, if the second gateway device 14 does not exist within the communication range of the sensor 12a, the sensor 12a continues to cache the immediately collected data in a queue format (for example, in the FIFO format described above). (without limitation) and continues to detect the presence of the second gateway device 14 within the communication range of the sensor 12a during the detection time period (for example, 7:00 AM to 8:00 AM). As described above, it is possible to arbitrarily make reasonable technical changes to steps S301 to S304. For example, in one embodiment, if the sensor 12a was previously unable to detect the second gateway device 12a within the detection window (e.g., 7:00 AM to 8:00 AM), the sensor The detection function of 12a may be shut off.

Note that steps S301 to S304 may be regarded as subsequent steps of steps S201 to S204. In other words, in the sensing data collection system 100, the sensor preferentially detects whether a fixed gateway device exists within its communication range. If a fixed gateway device is present, the sensor transmits the collected data to the fixed gateway device. If a fixed gateway device is not present, the sensor attempts to detect a mobile gateway device and transmits the collected data to the mobile gateway device. Therefore, the sensing data collection system 100 can detect the node resources of fixed gateway devices and mobile gateway devices, and achieve the function of automated data collection and transmission to the server 15.

FIG. 4 is a flowchart in which the sensing data collection system 100 executes a sensing data collection method. The flow of the sensing data collection method includes steps S401 to S404. It is assumed that all reasonable technical changes from step S401 to step S404 fall within the scope of the disclosure of the present invention. Steps S401 to S404 are as follows.

ステップＳ４０１からステップＳ４０４の詳細は以上に述べた通りであり、ここで省略する。センシングデータ収集システム１００において、センサはその通信モードを切り換えることができるため、例えば、固定式ゲートウェイ装置または移動式ゲートウェイ装置と通信できるため、自動化の、かつ高い利便性のデータ収集機能を提供できる。

The details of steps S401 to S404 are as described above, and will be omitted here. In the sensing data collection system 100, the sensors can switch their communication modes, for example, to communicate with a fixed gateway device or a mobile gateway device, thereby providing an automated and highly convenient data collection function.

In summary, the present invention provides a sensing data collection system and a sensing data collection method. A sensor within the data collection system preferentially detects whether a fixed gateway device is present within its communication range. If a fixed gateway device is present, the sensor transmits the collected data to the fixed gateway device. If a fixed gateway device is not present, the sensor attempts to detect a mobile gateway device and transmits the collected data to the mobile gateway device. Therefore, the sensing data collection system of the present invention can detect node resources of fixed gateway devices and mobile gateway devices and achieve automated data collection functions.

The above are preferred embodiments of the invention, and all equivalent changes and modifications within the scope of the claims of the invention fall within the scope of the invention.
