Specifically, the signal receiving port 11 of the sensing end is simulated by a software program as a signal transmission interface of the same type as the signal transmission interface of the corresponding environmental sensor W. For example, if the signal transmission interface of the environment sensor W is an I2C transmission interface, then the signal transmission interface of the signal receiving port 11 of the sensing end can be simulated as an I2C transmission interface by software programming to correspond to the environment sense I2C signal transmission interface of the detector W.

For example, in this embodiment, the data editing unit 13 converts the environmental sense value N into an ASCII code, in which the representative data type is added in front of the byte representing the numerical part of the environmental sense value N The code of is used as the discriminating byte. For example, "P" stands for pressure, "T" stands for temperature, "A" stands for altitude, and a number representing the number of data is added at the front.

In step S2, the sensing end control element 1 returns the sensing value data D when receiving the sensing value data request command. At this time, the communication end control element 2 enters a mode to receive the sensing value data D status. After the communication terminal control element 2 judges that the sensing value data D has been completely received, it proceeds to step S3, and the communication terminal control element 2 repeats the operation content of the step S1 for the second sensor end control element 1. Next, proceeding to step S4, the communication end control element 2 repeats the operation content of the step S2 to the second sensing end control element 1. In steps S5 and S6, the communication terminal control element 2 repeats the operation contents of the step S1 and the step S2 for the third sensing end control element 1.

In this step S7, the communication end control element 2 integrates the received sensed value data D into the upload data U, and transmits it to the wireless communication element 3. In step S8, the wireless communication component 3 transmits the uploaded data U to the message queue telemetry transmission (MQTT) server 42. After the message queue telemetry transmission (MQTT) server 42 releases the uploaded data U, the process proceeds to step S9. In the step S9, the communication terminal control element 2 transmits a piece of the upload data U to the cloud database 41 via the wireless communication element 3 at a predetermined time interval T. The predetermined time interval T in this embodiment is 15 seconds.

The sensing-end control element 2 processes the sensing signal M through the sensing-end signal fetch unit 12 and the data editing unit 13 to obtain the sensed value data D, and transmits the sensed data using the common signal transmission protocol Value data D to the communication control element 2. The communication end control element 2 receives the sensed value data D from each of the sensing end control elements 2 and processes it into the upload data U, and then transmits the uploaded data U to the remote end through the wireless communication element 3 The server 4 is for the user to subscribe and browse. In view of this, the advantages of the present invention include: it is possible to efficiently integrate a variety of environmental sensors W, and enable the various environmental sensors to be connected to the Internet of Things through a consistent signal transmission pipeline.
