The design of remote monitoring system software for construction machinery. The operating system is the core software of the entire monitoring system for construction machinery. This design mainly selects open-source and tunable Linux as the embedded operating system. The entire monitoring system realizes the interaction between the on-board terminal control system of construction machinery and the monitoring center through the GPRS wireless communication network program. The on-board terminal control system of construction machinery is mainly responsible for the collection and processing of various mechanical working state parameters on the construction site, and the monitoring center through control The instruction realizes the control and adjustment of the field equipment.

On-board terminal control system programming The main program of the on-board terminal control system in this design is mainly composed of four modules: system initialization subroutine, data acquisition subroutine, construction machinery operating status control subroutine and serial communication subroutine. The system initialization program is mainly responsible for clearing the data register, setting the control register, and setting the parameters of the serial port and GPRS communication module at the same time; the data acquisition module completes the A/D conversion and filtering processing of the on-site working condition parameters such as speed, temperature, and flow; construction machinery The job status control subroutine analyzes the collected working condition parameters to control the equipment to switch between heating, cooling, acceleration, deceleration and other states; the serial communication subroutine mainly completes the Socket connection between the data transmission module and the monitoring center, providing reliable, Stable data transmission.
