Abstract

The invention discloses an impact and vibration composite type sensing system for a road roller. The system comprises a photographing system, a distance measurement system, a running state monitoring and sensing system, a rolling compaction quality monitoring and sensing system, a controller, an execution system and a display, wherein the photographing system is capable of panoramically monitoring the pavement conditions in areas at the periphery of the road roller, the distance measurement system is used for measuring the distance between the road roller body and the pavement barrier in the peripheral area, the running state monitoring and sensing system respectively detects the steering, water temperature, hydraulic oil temperature and running speed of the road roller, the rolling compaction quality monitoring and sensing system is used for detecting the road compactness, the controller performs data operation, comparison, analysis and judgment and transmits an execution instruction, the execution system is controlled to execute corresponding actions by the controller, the photographing system is connected to the controller through an image processing unit; the distance measurement system, the running state monitoring and sensing system and the rolling compaction quality monitoring and sensing system are connected to the controller through a signal processor; the execution system and the display are also respectively connected to the controller. According to the system, the system conditions of the road roller can be monitored in real time.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a sensor system for an impact-vibration composite road roller. Background technique [0002] At present, road rollers are mainly used for compacting the base and road surface of highways, docks, airports and dams. During construction, it is often necessary to carry out road construction in both forward and backward directions, and the speed is relatively fast. When the road roller is in backward construction, the driver usually has to carry out construction operations in the cab and also take into account whether there are obstacles behind the road roller, which increases the difficulty of driving, and often causes construction safety accidents due to negligence in operation or occlusion of the viewing angle. To address this problem at home and abroad, the common methods are as follows: [0003] 1. Change the cab seat mode, adopt left and right sliding chairs or swivel seats, ...

AI Technical Summary

Problems solved by technology

[0003] 1. Change the seat mode of the cab, using left and right sliding chairs or rotating seats, so that the driver can operate sideways at a certain angle, but this method still has high driving difficulty and low safety

[0004] 2. The reverse alarm is used. When the driving handle is put into the reverse gear, the reverse alarm buzzer is driven to alarm, and the buzzer sound reminds the surrounding personnel to pay attention to safety, but the driver still cannot see the construction area behind the roller.

When there are obstacles in the area behind the construction, effective measures cannot be taken in time to avoid safety accidents

[0005] In addition, during the use of existing road rollers, external debugging equipment is often used to set the system parameters in the controller, and various analog instruments are used to monitor various equipment, such as using various analog instruments to monitor Water temperature, oil pressure, hydraulic oil temperature, engine speed and other equipment monitor the working status of the roller, which is not conducive to the specific operation and judgment of the operator, nor can it monitor the system status of the roller in real time

And when the external environment changes, it is impossible to change the system parameters in time to modify the working state of the machine
