[0098] The interface board communicates with the ultrasonic processing device 5 via RS485. Each interface board is connected to 10 ultrasonic probes 11. The total length from the ultrasonic probe 11 to the interface board or USGNet does not exceed 150m. The length of the network cable follows the conventional network cable length and relay rules. The network cable is an industrial-grade network cable.

[0099] A multi-point monitoring and control method for an ultrasonic detection device comprises the following steps:

[0100] SI1: Receive the bolt command signal to be measured;

[0101] SI2: emits ultrasonic waves to the bolt to be tested;

[0102] SI3: Receive ultrasonic echoes and generate measurement data;

[0103] SI4: Retrieve the pre-stored data of the bolt under test;

[0104] SI5: The measured data of ultrasonic echo is compared with the pre-stored data and the preload force is calculated;

[0105] SI6: Output preload force.

[0106] Before installing the bolts, stress detection is first performed on the bolts and used as pre-stored data. Since the installation of each machine requires a large number of bolts, the bolts that need to be tested are selected before monitoring. After obtaining the ultrasonic echo reflected by the bolt, the pre-stored data before the bolt is installed is retrieved, and the pre-tightening force is obtained after comparing the data. When measuring the pre-tightening force of each bolt, it is calculated based on the stress of each bolt itself, so that the measurement of the pre-tightening force of each bolt is more accurate, mismeasurement is prevented, and the monitoring effect of the bolt is improved. The pre-stored data in step SI4 is the stress data measured by ultrasound when each bolt is not tightened; each bolt is provided with a corresponding ultrasonic probe 11.

[0107] The present invention can remotely detect the preload force of each object 12 to be tested in real time, and can know the temperature during the test; each object 12 to be tested can be accurately located through the interface board group 4, and the ultrasonic processing device can be carried outdoors or used on-site. The ultrasonic non-destructive testing technology has a relatively strong penetration ability for most media, and the penetration ability can reach several meters in some metal materials, and does not cause any damage to the object 12 to be tested.

[0108] Ultrasonic testing of preload force can measure quickly and can also be used for system integration to achieve automated or semi-automated stress testing; the measurement depth is large, the near-surface stress detection depth is within 2mm, and the body stress detection depth is more than 10mm; there is no radiation, the operation is safe, and no protection is required; it can measure stress, detect defects inside the test piece, and can also be used for high-precision thickness measurement; it is applicable to a wide range of materials, and in theory can be applied to any non-sound-absorbing material.

[0109] In the present invention, the ultrasonic probe 11 can be connected to the bolt to be tested by welding or bonding. The bonding probe package Z2 has the advantages of easier installation, low processing difficulty, low production cost, and high detection accuracy without destroying the strength of the bolt itself. The two can be selected by users according to their own conditions.
