Intelligent starting and power-failure protection system of laser radar

Abstract

The invention, which relates to the technical field of a laser radar system, discloses an intelligent starting and power-failure protection system of a laser radar. A power supply unit consists of a generator unit and a commercial power supply unit; the generator unit and the commercial power supply unit are connected with a UPS unit; the UPS unit is connected with an ARM control unit connected with a parameter storage unit and a PC unit; and the ARM control unit is connected with an execution relay unit connected with a function module. The execution relay unit is used for completing functions of self-starting and power failure protection of the system. The ARM control unit carries out serial port communication to complete peripheral data collection; the working state of the laser modulein the function module is controlled by transferring a control command of the PC unit; the PC unit is responsible for running the acquisition software and analysis software and carries out communication with the ARM control unit through the serial port to complete data exchange and control deployment. Therefore, the start-up problem as well as the power continuity problem of the laser radar beforeand after data collection is solved.

Description

technical field [0001] The invention relates to the technical field of laser radar systems, in particular to a laser radar intelligent start-up and power-off protection system. Background technique [0002] The lidar system is divided into multiple functional modules, such as industrial computer, laser, purge device, photomultiplier tube and scanning head. On the one hand, when starting the lidar system, it is necessary to supply power to each module first. On the other hand, the system needs to meet certain conditions before and after data collection. At present, the lidar system has two startup modes: manual module-by-module startup or one-button multi-module startup at the same time. Manual module-by-module startup refers to manually powering each functional module one by one in a certain order; one-button multi-module startup at the same time is It means that the system energizes each module at the same time immediately after the main switch is turned on. Before data ...

AI Technical Summary

Problems solved by technology

[0003] Both the existing two laser radar start-up modes have certain shortcomings. Manually starting modules one by one requires manual completion of multiple start-up actions, and has a certain sequence, which is very inconvenient to operate, and is not conducive to the unattended design of the later laser radar system; Simultaneous start of multiple modules with one button Since the power supply is completed in an instant, the power supply needs to provide a large instantaneous power, which puts high demands on the power supply, thus increasing the cost

In addition, the large instantaneous power will generate radiation and space radiation, which will affect the stability of the weak current control system

[0004] If the power supply of the laser radar system is suddenly lost during data collection, the data collection will be terminated, resulting in discontinuous data collection and the system cannot timely feedback the emergency event to the operator; Call, at this time the lidar operating system not only has a startup problem, but also has a collection problem, and the operator must visit the site in person to carry out the next step of the collection work
