the intelligent Internet of things ultrasonic probe comprises an intelligent Internet of things ultrasonic probe body, a standard test block and a base, wherein a is the front edge distance of the intelligent Internet of things ultrasonic probe body, X is the distance between the front edge of the intelligent Internet of things ultrasonic probe body and the standard test block, and L is the standard test block distance.

In this step, the controller obtains the consumable wear value by processing the consumable wear information of the consumable wear calculation module, obtains the measurement accuracy of the detection element by calculation, and can record the working duration of the detection element in real time, and after obtaining the information, stores the consumable wear value, the measurement accuracy, the working duration and the basic information in the memory on the miniature circuit board.

And S34, the communication module sends the consumable wear information, the measurement accuracy and the working time to the cloud server through the upper computer.

In the step, the memory sends the consumable wear information and the working time length information stored in the communication module to the cloud server through the upper computer. The cloud server is provided with a probe information management system, the probe information management system manages according to the basic information of each ultrasonic probe, and probe information is updated when an upper computer is replaced or the upper computer is started. The updated ultrasonic probe information may include the calculation parameter information and the working time of each ultrasonic probe, wherein the calculation parameter information may be an empirical constant in calculating the measurement accuracy, for example, the accuracy coefficient c of the straight probe in the above measurement accuracy calculation formula_{Straight bar}Precision coefficient of tilt probeStandard frequency f of ultrasonic probe of intelligent Internet of things₀Measuring the height h of the wave trough and the deviation D of the sound axis in the x and y directions_x，D_yThe front edge distance a of the intelligent Internet of things ultrasonic probe and the distance X between the front edge of the intelligent Internet of things ultrasonic probe and the standard test block are one or more.

Specifically, the cloud server performs summary analysis according to data (such as working hours, consumable wear values and measurement accuracy) uploaded by each intelligent internet of things ultrasonic probe, analyzes how the calculation parameters of the ultrasonic probe change according to the analysis results at intervals according to the uploaded data (such as the working hours, the consumable wear values and the measurement accuracy), and then updates the information of the corresponding ultrasonic probe according to the analysis results.

S36, a probe diagnosis module arranged on the upper computer analyzes the consumable wear value, the measurement accuracy and the working duration of each ultrasonic probe, and when the consumable wear value is larger than a wear threshold, or the measurement accuracy is smaller than an accuracy threshold, or the working duration exceeds the industry specified maximum duration, a probe replacement prompt is carried out.

In this step, probe diagnosis module obtains health management model to all ultrasonic probe's operating duration, consumptive material wearing and tearing information, measurement accuracy through the training, will await measuring ultrasonic probe's operating duration information, consumptive material wearing and tearing information, measurement accuracy input health management model obtains prediction life, works as when prediction life is less than the life threshold, it is right the suggestion is changed to the intelligence thing networking ultrasonic probe that awaits measuring.

From this, the method of suggestion is changed to ultrasonic transducer in the intelligence thing networking ultrasonic transducer system that this specification provided, through the work information of real-time detection detecting element, and send work information to probe information management system and carry out the analysis back, can predict intelligence thing networking ultrasonic transducer's life, thereby can be more accurate change the suggestion to intelligence thing networking ultrasonic transducer, avoid because the wasting of resources that the change caused when the ultrasonic transducer state is good, and the potential safety hazard that ultrasonic transducer excessive wear caused, and the cost is reduced, promote the ability to ultrasonic transducer prediction and maintenance. Meanwhile, in the intelligent ultrasonic probe system of the internet of things provided by the embodiment of the specification, each ultrasonic probe has a unique ID, the use state of the ultrasonic probe can be monitored in real time according to the ID, the information of the ultrasonic probe can be updated according to the historical data of the ultrasonic probe, and the accuracy and precision of measurement are further improved.
