DETAILED DESCRIPTION OF THE INVENTION The movement trajectory monitoring and recording device for construction machinery according to the present invention will be explained in accordance with the following items.

A. Industrial field of application B8 Summary of the invention C1 Background art and its problems 0 Means for solving the problems E. Examples [Figures 1 and 2] F0 Effects of the invention (A. Industrial application) FIELD OF THE INVENTION The present invention relates to a novel movement trajectory monitoring and recording device for construction machinery. For more information, see Automatically record the trajectory of construction machinery,
It is an object of the present invention to provide a new construction machine movement trajectory monitoring and recording device that can accurately grasp the operation status of the construction machine by analyzing the records.

(B. Summary of the Invention) The movement trajectory monitoring and recording device for a construction machine according to the present invention includes various sensors that detect movements of various parts of the construction machine and a data recording section that records data detected by the various sensors on a recording medium. In addition, by analyzing various data recorded on the recording medium using a data analysis device, it is possible to accurately grasp the operation status of the construction machine.

(C. Background technology and its problems) In dam construction, road construction, ground preparation work, etc., recording the movement trajectory of construction machines, such as compaction machines such as vibrating rollers, can greatly improve the reliability of the construction work. In addition to being an essential factor for ensuring safety, it also has important significance as an indicator for instructions to workers.

However, at present, there is nothing that automatically records the operation status of construction machines, and the only way to understand the operation status of construction machines is through reports from workers or records from managers who have actually visually inspected the machines.

(D. Means for Solving the Problems) The movement trajectory monitoring and recording device of the construction machine of the present invention records various sensors that detect the movement of each part of the construction machine and the data detected from the various sensors on a recording medium. A data recording section is provided in a construction machine, and various data recorded on the recording medium is analyzed by a data analysis device.

Therefore, according to the construction machine movement trajectory monitoring and recording device of the present invention, the operating status of the construction machine can be accurately grasped.

(E. Embodiment) [FIGS. 1 and 2] A description will be given of an embodiment in which the moving trajectory monitoring and recording device for a construction machine according to the present invention is applied to a vibrating roller machine.

In the figure, reference numeral 1 denotes a single-axis, restrained type vibrating roller machine, which includes a driving vehicle 4 equipped with a driver's seat 2 and driving wheels 3.3, and the driving vehicle I! 4 and a roller section 6 equipped with a vibrating roller 5 for compacting the ground, etc.

Further, the drive side vehicle 4 and the roller section 6 are connected at the rear of the drive side vehicle 4, and the connection angle of the connection section 7 can be changed by steering a handle 8 disposed in the driver's seat 2. It has become.

Reference numeral 9 denotes an operating angle sensor disposed at the connecting portion 7 between the drive side vehicle 4 and the roller section 6, which uses a resistive sensor such as a potentiometer to convert the operating angle into electrical resistance, thereby controlling the steering wheel operation. This is to detect the steering angle.

Reference numeral 10 denotes an azimuth angle sensor installed in the driving vehicle 4, which uses an electric azimuth compass to detect the vibration roller machine 1.
This is to detect the direction of movement of the vehicle.

Reference numeral 11 denotes a distance measurement sensor installed in the roller section 6, which measures the number of revolutions of the vibrating roller 5 of the roller section 6 and detects the amount of movement of the vibrating roller 5.

12 is a vibration sensor installed in the driving vehicle 4,
This is an 0N10FF sensor that detects the operation of the vibrating roller 5.

13 is each of the above-mentioned sensors (operation angle sensor 9, azimuth sensor 1
0, movement distance sensor 11, and vibration sensor 12).
It is equipped with memory such as IC memory.

Reference numeral 14 denotes a writing device, such as a floppy disk recorder, for writing the data stored in the data recording section 13 onto a recording medium 15, such as a floppy disk.

Reference numeral 16 denotes a data analysis device for analyzing the operational status of the vibrating roller machine 1, and includes a calculation unit 17 consisting of a central processing unit CPU, a read-only memory ROM, a random access memory RAM, etc., and an input/output board for each calculation unit. 18, a printer 19, a CR7 display section 2o, and a reading device 21 for reading data written on the recording medium 15, such as a floppy disk reader;
It consists of

Therefore, the operating state of the vibrating roller machine 1 can be grasped as follows.

That is, each of the above-mentioned sensors (operation angle sensor 9, azimuth angle sensor 1
The movement of each part of the vibrating roller machine 1 (handle 8, vehicle body, vibrating roller 5) detected by the moving distance sensor 11 and vibration sensor 12) is grasped as an electrical signal, and each electrical signal is recorded as data. A writing device 14 writes the recorded data onto a recording medium 15 such as a floppy disk, a memory bag, a magnetic tape, etc.

Then, data written on the recording medium 15 recording the movements of each part of the vibrating roller machine 1 is transferred to a data analysis device 16.
The data read by the reading device 21 is temporarily stored in the random access memory RAM, and the data is analyzed by the central processing unit CPU according to a predetermined program written in the read-only memory ROM. When the data is analyzed, the movement of each part of the vibrating roller machine 1 is displayed on the CR7 display section 20, and is also printed out by the printer 19 to obtain a hard copy.

(F. Effects of the Invention) As is clear from the above description, the motion trajectory monitoring and recording device of the construction machine of the present invention includes various sensors that detect the movement of each part in the operating state of the construction machine, and the various sensors. The construction machine is equipped with a data recording unit that records the movement of each part detected by the system as an electrical signal on a recording medium, and a data analysis device that analyzes various data recorded on the recording medium. do.

Therefore, according to the construction machine trajectory monitoring and recording device of the present invention, the movement trajectory of the construction machine can be automatically recorded and each recorded data can be analyzed, and the operation status of the construction machine can be determined very easily. can be grasped.
