[0038] In the first embodiment, the application is a temperature and humidity detection application. The monitoring node 10 includes a temperature sensor for sensing the temperature of the measured air and a humidity sensitive capacitor for sensing the humidity of the measured air. For the humidity-sensitive capacitor, it is used to convert the relative humidity in the measured air into a capacitance value, and convert the capacitance value into a frequency signal through a subsequent connected oscillating circuit, through, for example, a single-chip microcomputer or a digital signal processing chip DSP After digital signal processing, the frequency signal is converted into a humidity value that can be displayed on a display device.

[0039] In practical applications, generally, when the gateway node 12 receives the request data reading instruction sent by the service platform 14, the gateway node 12 obtains the temperature data of the temperature sensor at the connected monit...

[0041] In the second embodiment, the application is an electrical equipment management and control application. The monitoring node 10 includes a voltage sensor and a current sensor respectively used to detect the voltage and current of the electrical equipment. By using the voltage sensor and the current sensor, the voltage, current, power, electricity, power factor, and active power of the electrical equipment can be detected. Power parameters such as power. In addition, the application for managing and controlling the electrical equipment further includes an intelligent switch for controlling the electrical equipment.

[0042] In practical applications, when the gateway node 12 receives the request data reading instruction issued by the service platform 14, the gateway node 12 obtains the voltage data sensed by the voltage sensor at the connected monitoring point and the obtained voltage data by broadcasting. The current data sensed by the current sensor is obtained, the o...

[0044] In the third embodiment, the application is an air conditioner remote control application. The monitoring node 10 includes an infrared carrier receiver and an infrared generator. The infrared carrier receiver is fully compatible with encoding formats such as NEC, PHILIPS, TOSHIBA, and PANASONIC, and can decode and learn various types of air conditioner remote controls on the market.

[0045] In practical applications, when the gateway node 12 receives a remote wireless learning instruction sent by the service platform 14, the infrared carrier receiver is started to perform carrier analysis and decoding. If the analysis is successful, it means that the remote control learning is completed; if the analysis fails, the gateway node 12 returns the EERO information to the service platform 14 as a reference for the service platform 14 to perform the next action. In the case of completing the remote control learning, when the gateway node 12 receives the execution control comm...
