This traditional ultrasonic testing instrument based on embedded system needs to develop the design of sensor, embedded hardware and embedded software at the same time, which has complex circuit design, difficult system debugging, high design cost, heavy workload, long development cycle and product failure. Problems such as poor compatibility of software and hardware.
