[0028] This embodiment provides an effective prestressed wireless detection device based on the reverse pulling method, such as Figure 1 As shown, it includes a force-bearing body 5, the upper part of the force-bearing body 5 is provided with a protective component, the force-bearing body 5 is embedded with a displacement sensor 5-4 for collecting the displacement generated by the measured clip, the lower part of the force-bearing body 5 is connected to a force sensor cabin 6, the force sensor cabin 6 is provided with a force sensor 6-2 for collecting the pressure borne by the device, the bottom of the force sensor cabin 6 is connected to a flange base 7, the flange base 7 is provided with a data acquisition and processing center 8, and the displacement sensor 5-4 and the force sensor 6-2 both establish communication with the data acquisition and processing center 8.

[0029] As an implementation method, the force-bearing body 5 is made of bearing steel. During operation, the detection device will withstand the extrusion force generated by the jack pulling, which places strict requirements on the material of the device. Therefore, the force-bearing body 5 and other embedded components need to comprehensively consider the load-bearing capacity of the force-bearing body. By adopting bearing steel material, the two ends of the force-bearing body 5 are sufficient to withstand 300KN pressure.

[0030] As an implementation, please refer to Figure 2 The force-bearing body 5 includes a displacement extension rod 5-2, which is connected to the probe of the displacement sensor 5-4 and is used to extend the probe of the displacement sensor 5-4. It is closely attached to the dustproof component to balance the measuring point. Limit baffles 5-3 are provided at both ends of the displacement sensor 5-4 to limit the displacement distance of the displacement extension rod 5-2 and reduce the probability of damage to the displacement sensor 5-4 during large friction impact. A buffer spring 5-6 is provided at one end of the displacement sensor 5-4 away from the displacement extension rod 5-2 to buffer the impact transmitted to the probe of the displacement sensor 5-4 when the measuring clip is unanchored and displaced, so as to protect the displacement sensor 5-4.

The displacement extension rod 5-2 is set close to the dust cover 1 to prevent dust from entering the sensor body.

The rod-shaped RF antenna 8-3 is fixedly connected to the flange base 7 through the RF antenna support 8-2.

[0036] As an implementation method, the data acquisition and processing center 8 wirelessly communicates with the remote receiving device via a 433 MHz radio frequency communication band and a Modbus-like communication protocol.

[0037] The present invention provides an effective prestress wireless detection device based on the back-pull method. By collecting real-time data of the force-bearing body for analysis, and using high-precision sensors, it can accurately collect prestress data within a wide range of temperature and pressure. It is suitable for instant or on-demand detection scenarios, so that prestress detection can be performed efficiently and accurately. The data acquisition and processing center performs instant analysis and processing on the collected data, and uses advanced algorithms to ensure the accuracy and reliability of the data. The data is wirelessly transmitted through the 433MHz radio frequency communication band and Modbus-like communication protocols, which further improves the stability and anti-interference ability of data transmission.
