Abstract
According to the traditional bridge cable measurement system, the accuracy of the bridge cable measurement is low, and the measurement time is long. Based on the automatic control technology of the climbing robot, a new bridge cable measurement system is designed. We design system hardware through CIS drive circuit, main controller, and communication module; design system software on the basis of hardware design; obtain the motion control equation of orthogonal joint cable climbing robot through DH transformation; and apply this equation to the bridge cable measurement system. The bridge cable measurement model is constructed, and the bridge cable measurement system design is completed through the system hardware design and software design. The simulation results show that the designed system has higher accuracy in measuring bridge cables and shorter measuring time.
Highlights
As a new type of bridges, cable-stayed bridges are being used more and more in actual production. ey have beautiful appearance, relatively low cost, and good seismic resistance
As the main load-bearing structure of cable-stayed bridges and suspension bridges, the effective metal bearing area of the cable is directly related to the safety and service life of the bridge, so it is necessary to Wireless Communications and Mobile Computing measure the bridge cable
In order to solve the defects of low measurement accuracy and long time of traditional bridge cable measurement system, an automatic control technology of cable climbing robot based on bridge cable measurement system is designed, and the effectiveness of the system is verified by simulation experiments. is method can be applied to the regular measurement of bridge cables. rough the rapid and accurate detection of bridge cables, the risk factors can be found in time to maintain the safety of the bridge
Summary
As a new type of bridges, cable-stayed bridges are being used more and more in actual production. ey have beautiful appearance, relatively low cost, and good seismic resistance. Yi et al designed an ultrasonic testing system for axial force of cable clamp screw of suspension bridge [7]. In order to solve the defects of low measurement accuracy and long time of traditional bridge cable measurement system, an automatic control technology of cable climbing robot based on bridge cable measurement system is designed, and the effectiveness of the system is verified by simulation experiments. 2. Design of Bridge Cable Measurement System Based on Automatic Control Technology of Cable Climbing Robot. E hardware design part of the bridge cable measurement system includes the CIS drive circuit, the main controller, and the communication module. E function of the main controller is as follows: the wireless serial port communicates with the host computer, connects to the CAN bus, and processes the large amount of data fed back. The data link layer is a commonly used duplex 8N1 (8 data bits, no parity, 1 stop bit) serial frame with a baud rate of 9600, and the main controller interrupts the receiving wireless
