1、 Product Introduction

The prestressed intelligent tensioning monitoring system is a control system developed based on dynamic control of the tensioning construction process quality during the production of prefabricated beams.

The intelligent tensioning technology for bridge prestressing is matched with remote monitoring technology, forming a remote monitoring and management system for bridge prestressing construction quality. It can achieve "real-time tracking, process control, dynamic acceptance, and timely remediation" of prestressing quality management. Using this system, a series of problems in the prestressing construction process of bridges are solved, reducing the influence of human factors during the construction process and effectively ensuring the achievement of construction technical indicators. 3G/4G mobile network is used to generate data to the server database, and through built-in algorithm analysis, warning analysis function management is provided for management personnel.

2、 Product Features

1 data acquisition

Using IoT technology to collect and upload key data (tensioning date, tensioning result, beam hole number, theoretical tensioning force, actual tensioning force, tensioning force error, theoretical elongation, actual elongation, elongation error, tensioning time, etc.) during prestressing operations to the monitoring system platform. By analyzing and comparing quality data and alerting for excessive data, dynamic monitoring of the quality of the operation process is achieved to ensure quality control of precast beam prestressing construction operations.

2 Early warning monitoring

The prestressed intelligent tensioning monitoring system achieves dynamic monitoring and warning of the quality of the operation process by analyzing and comparing quality data and issuing alerts for excessive data, ensuring the quality control of prefabricated beam prestressed construction operations.

3 practical application

In practical applications, the prestressed intelligent tensioning equipment consists of three main parts: the system host, the control host (oil pump), and the jack, with stress as the control indicator and elongation error as the calibration indicator.By using sensing technology to collect data on the working pressure of each tensioning device (jack) and the elongation and retraction of steel strands, the prestressed intelligent tensioning monitoring system embeds GIM into the tensioning device and displays the data on the prestressed intelligent tensioning system platform.
