2.2.2 RAE1 IOT AE System
RAE1 IOT AE is designed and developed/developing for burst AE signals such as
cracking signals. Table 2.1 is the specification and Fig. 2.4 is the system functional
block diagram.
New RL1/RAE1 IOT AE systems are in developing and can be the integrate
structure or separate structures as shown in Fig. 2.5 for various applications.
Figure 2.5 shows the integrate and separate RL1/RAE1: Above right: integrate of
sensor/battery/AE module/4G module; Above left: DC power and sensor are out of
metal cylinder with AE module and 4G module; Above center: 4G module out of
cylinder; Below left: DC power out of the cylinder; Below right: Different cylinders
holding different parts inside.
