2.3 Testing of RAE1 and RL1 IOT AE System
2.3.1 Testing Layout and Procedures
The water tap and water pipeline are used for generating water leakages. The sensors
are placed on the water tap to monitor the water leakages of the tap. The water
leakages are generated by operate the tap at the positions of close, open a little, open
large, corresponding to no leakage, small leakage and large leakages. Figure 2.6
shows the testing layout and the RAE1 and RL1.
2.3.2 The RL1 Testing Data
The setting of RL1 in this experiment: 16 bit sampling accuracy; 200 kHz sampling
rate; filter 20–100 khz; manual sampling once every 5 min; ls35 sensor, resonance
frequency 15–70 khz, central resonance frequency 35 kHz. The operation process of
faucet controlling water flow is shown in Table 2.3.
Access the server through the laptop, and the historical data is shown in Table
2.2. It can be clearly distinguished from the historical RMS data of the five stages.
Figure 2.7 shows that alarm data can be notified to users through WeChat official
account, e-mail, text message, etc.
