Description

The present invention relates to a compaction machine and particularly relates to a technique for controlling the number of compactions.

The compaction work is generally performed by using a tire roller or a vibrating roller (compacting machine) for compacting work (compacting work).
In this rolling work, the number of times of rolling is determined by a test work or the like performed in advance, so that the worker needs to perform the work while memorizing the position and the number of times of rolling.

Therefore, regarding the rolling compaction position, the construction range is divided so as to form a lane in one direction, and after repeating the rolling compaction work a predetermined number of times for each lane, the work is moved to the adjacent lane. By repeating the work, it is common to suppress overlapping rolling work and leakage of rolling work.

However, as for the number of rolling compactions (the number of rolling compactions), the operator must memorize the number of rolling compactions for each lane. There was a risk that an error would occur with the number of pressures.

Therefore, it is conceivable that the operator counts the number of rolling compactions using a counter.
Further, a technique has been developed in which the rolling position and the number of rolling compactions are recorded using GPS and displayed on a map to manage the number of rolling compactions (Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-282448

However, when the counter is used as described above, it is necessary for the operator to operate the counter every time the rolling compaction work is completed, so that there is a risk of forgetting to operate the counter.
Further, as in the technique disclosed in Patent Document 1, the compaction machine that manages the number of compactions using GPS has a problem that the price of the compaction machine as a whole is high because the GPS device is expensive. be.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a rolling compaction machine capable of controlling the number of rolling compactions with an inexpensive configuration.

In order to achieve the above object, the compaction machine of the present invention includes a machine body, wheels attached to the machine body, a recording unit for recording the number of times of rolling compaction work per lane, and the above. a notification unit for broadcasting knowledge the number of rolling pressure circuit recorded in the recording unit, and the forward-reverse operation detection unit for detecting a reverse operation before the previous SL airframe, the compaction machines with, the number of rolling pressure circuit to 0 The rolling compaction start button to be set, the wheel speed sensor that detects the rotational speed information of the wheel, the turn- back determination unit that determines whether or not the traveling direction of the aircraft in the front-rear direction has been switched, and the number of rolling compactions are managed. A rolling compaction frequency management unit, a construction requirement determination unit for determining whether or not the rolling compaction work meets predetermined construction requirements, and a rolling compaction for calculating the rolling compaction distance at which the rolling compaction work is performed. It has a distance calculation unit, the compaction distance calculation unit calculates the compaction distance based on the rotation speed information of the wheel input from the wheel speed sensor, and the turn-back determination unit is the front and rear. Susumu when it is detected that the traveling direction in the longitudinal direction of the machine body has been toggle by the operation detection unit determines that the traveling direction in the longitudinal direction of the machine body is switched, the rolling pressure circuit number management unit, the folded When it is determined by the determination unit that the traveling direction of the aircraft has been switched and the number of rolling compactions is 0, the rolling compaction distance calculated by the rolling compaction distance calculation unit is recorded as the length of the lane. When it is determined by the folding determination unit that the traveling direction of the machine has been switched , and when the construction requirement determination unit determines that the compaction work satisfies the construction requirement , the above-mentioned 1 is added to the number of rolling compactions recorded in the recording unit, and the construction requirement determination unit determines the length of the lane in which the rolling compaction distance calculated by the compaction distance calculation unit is recorded in the recording unit. when greater than a predetermined rate, it determined that comprises a construction requirements.

As a result, the forward-reverse operation when it is determined that the traveling direction is switched in the longitudinal direction of the aircraft when it detects the forward and reverse operation of the detection unit to drunk aircraft bodies, fuselage once the rolling compaction industry per lane By adding 1 to the number of rolling compactions up to that point, it is possible to automatically count the number of rolling compactions without having to count the number of rolling compactions by the operator. ..
In addition, the construction requirement determination unit determines whether or not the compaction work meets the construction requirement, and counts the number of rolling compactions only when it is determined that the construction requirement is satisfied, thereby satisfying the construction requirement. It is possible to improve the construction accuracy by counting only the rolling compaction work to be performed.
Further, when the rolling distance calculated by the rolling distance calculation unit is larger than a predetermined ratio of the length of the lane required for the rolling work, the construction requirement determination unit determines that the construction requirement is satisfied. Therefore, it is possible to exclude from the count of the number of rolling compactions the rolling compaction work that does not meet the construction requirements such that the number of rolling compactions is insufficient for a specific position.
In addition, by calculating the length of the lane for the lane to be compacted by the compaction distance calculation unit when the compaction work is first performed, for example, it is necessary to separately measure the construction distance, or by manual input by the operator.

As a result, when the speed of the aircraft calculated by the aircraft speed calculation unit based on the rotation speed information of the wheels input from the wheel speed sensor is equal to or less than the speed limit, the construction requirement determination unit determines that the construction requirements are satisfied. By doing so, the rolling work that does not meet the construction requirements, such as when the rolling work is performed at a speed faster than the speed determined based on the test construction performed in advance of the road construction, is excluded from the counting of the number of rolling times. Is possible.

It is preferable to determine whether or not the lane has been changed.

As a result, whether or not the aircraft has changed from the lane where the rolling work is performed to the adjacent lane is determined by the correlation between the steering angle detected by the steering operation angle detection unit and the speed of the aircraft calculated by the aircraft speed calculation unit. By making a determination, it is possible to improve the accuracy of determining whether or not the aircraft has changed from the lane where the rolling compaction work is performed to the adjacent lane.

According to the compaction machine of the present invention, when it is determined that the traveling direction of the aircraft in the front-rear direction is switched when the operator detects the forward / backward operation of the aircraft by the existing forward / backward operation detection unit, the aircraft is set to 1. By determining that the rolling work per lane has been performed once and adding 1 to the number of rolling compactions up to that point, the existing forward / backward operation detection can be performed without the operator counting the number of rolling compactions. The number of rolling compactions can be automatically counted using the unit.

With reference to FIG. 1, a side view of the airframe 1 according to the present invention is shown.
The machine body 1 is a tire roller provided with wheels 3 and an operation unit 5. This machine body 1 can be compacted in asphalt pavement work by performing compaction work described later. The wheels 3 are rubber tires, and can be rotated by a drive device (not shown) to drive the aircraft 1 and decelerate to decelerate the aircraft 1.

Referring to FIG. 2, a perspective view of the operation unit 5 as viewed from the rear of the machine body is shown. The operation unit 5 includes a forward / backward lever (forward / backward operation detection unit) 11, a steering 13, a speedometer 15, a spray switch 17, a parking switch 19, a counter (notification unit) 21, a compaction start button 23, and a compaction count setting button. It includes a (rolling number input unit) 25 and a speaker (notification unit) 27. The operation unit 5 is a device for an operator to perform various operations such as traveling, steering, braking, and watering of the machine body 1.

The forward / backward lever 11 is a lever that controls an HST (Hydraulic Static Transmission) (not shown) by being operated by an operator, and switches the traveling direction of the machine body 1 in the front-rear direction by changing the rotation direction of the wheels 3. The forward / backward lever 11 can be switched to three positions: a forward position F, a neutral position N, and a reverse position R.

When the operator depresses the accelerator pedal 31, which will be described later, when the forward / backward lever 11 is in the forward position F, the HST is controlled so that the aircraft 1 can move forward. Further, when the operator depresses the accelerator pedal 31 when the forward / backward lever 11 is in the reverse position R, the HST is controlled so that the aircraft 1 can move in the backward direction. On the other hand, when the forward / backward lever 11 is in the neutral position N, the HST is controlled so that the aircraft 1 does not accelerate even if the operator depresses the accelerator pedal 31.

The steering 13 is a steering device that is operated by an operator to rotate the wheels 3 on the front side of the machine body about the vertical direction of the machine body and adjust the traveling direction of the machine body 1 in the left-right direction. The steering 13 is provided with a steering angle sensor (steering operation angle detecting unit) 13a for detecting the steering angle.

The speedometer 15 is a meter that displays the speed of the machine body 1 calculated from the rotation speed of the wheels 3 detected by, for example, the wheel speed sensor 3a provided in the vicinity of the wheels 3. The speedometer 15 also displays, for example, the rotation speed of an engine (not shown).

The spray switch 17 is a switch capable of controlling a watering unit (not shown) by operating the spray switch 7 to intermittently or continuously spray a liquid agent or water from the spray nozzle 7 to the wheel 3.
The parking switch 19 is a switch for operating an electric parking brake switch (not shown), and by turning it on, the rotation of the wheels 3 can be locked and the aircraft 1 can be parked.

The counter 21 is a digital meter that displays the number of rolling compactions C calculated by the rolling compaction number management control described later and notifies the operator of the number of rolling compactions. Below the counter 21, a rolling compaction start button 23 and a rolling compaction number setting button 25 are arranged. The rolling compaction start button 23 is a button that is first pressed when starting the rolling compaction construction described later.

The rolling compaction number setting button 25 is a button that can be arbitrarily pressed by the operator, and it is possible to input the number of scheduled rolling compaction operations per lane (registration number C described later). .. The rolling number setting button 25 may be used as a rolling number correction button capable of arbitrarily changing the rolling number C displayed on the counter 21 after pressing the rolling start button 23.
The speaker 27 is a speaker capable of giving a notification or warning by a sound such as a voice or a buzzer sound.

An accelerator pedal 31 and a brake pedal 33 are arranged below the operation unit 5. The accelerator pedal 31 is a pedal capable of accelerating the wheel 3 and accelerating the body 1 by the operator stepping on the pedal. The accelerator pedal 31 allows the operator to control the HST by adjusting the amount of treading pressure to adjust the speed of the aircraft 1 in the traveling direction. Further, the accelerator pedal 31 can decelerate the airframe 1 at a predetermined acceleration by the so-called hydraulic brake by the HST when the operator takes his / her foot off the accelerator pedal 31.

The brake pedal 33 is a pedal that brakes the wheel 3 by, for example, a friction braking device using a brake pad when the operator presses on the pedal. The brake pedal 33 allows the operator to adjust the degree of braking by the friction braking device to brake the wheel 3 by adjusting the amount of treading pressure. Further, the brake pedal 33 can decelerate the machine body 1 at an acceleration larger than a predetermined acceleration by adjusting the pedal pressure amount by the operator.

The ECU 40 is a control device for performing comprehensive control including engine operation control, and includes an input / output device, a storage device (ROM, RAM, non-volatile RAM, etc.), a central processing unit (CPU), and the like. It is configured.

With reference to FIG. 3, the connection configuration of the ECU 40 is shown in a block diagram.
A wheel speed sensor 3a, a forward / backward lever 11, a steering angle sensor 13a, a rolling start button 23, a rolling number setting button 25, a brake pedal 33, and an accelerator pedal 31 are electrically connected to the input side of the ECU 40. There is.

As a result, the wheel speed sensor 3a inputs the rotation speed information of the wheel 3, the forward / backward lever 11 inputs the forward / backward operation information by the operator, and the steering angle sensor 13a inputs the rotational speed information of the operator to the ECU 40. The steering operation information is input, the braking operation information by the operator is input from the brake pedal 33, and the acceleration operation information by the operator is input from the accelerator pedal 31.
Further, information regarding the rolling compaction construction, which will be described later, is input to the ECU 40 from the rolling compaction start button 23 and the rolling compaction number setting button 25.

On the other hand, the counter 21 and the speaker 27 are electrically connected to the output side of the ECU 40. As a result, the ECU 40 can display the number of rolling compactions on the counter 21 and emit a notification sound or a warning sound from the speaker 27 to the operator.

The ECU 40 has a rolling distance calculation unit 42 and a rolling speed calculation unit (airframe speed calculation unit, aircraft acceleration calculation unit) 44 as calculation units, and a turn-back determination unit 62, a construction requirement determination unit 64, and a lane change determination as determination units. The unit 66 and the warning determination unit 68 are provided with a recording unit 52 for recording calculation and determination results by each calculation unit and the determination unit.

The rolling distance calculation unit 42 is a calculation unit capable of calculating the mileage of the machine body 1 based on the rotation speed information of the wheels 3 input from the wheel speed sensor 3a.
The rolling speed calculation unit 44 is a calculation unit capable of calculating the speed of the machine body 1 based on the rotation speed information of the wheels 3 input from the wheel speed sensor 3a.

The turn-back determination unit 62 determines that the turn-back determination unit 62 has turned back on the lane where the rolling compaction work described later is performed when the forward / backward lever 11 is operated by the operator to switch the traveling direction of the machine body 1 in the front-rear direction. It is one of the determination units to be prepared.
The construction requirement determination unit 64 is one of the determination units provided in the ECU 40 that executes the determination and determination of steps S50 to S70, which will be described later.

The lane change determination unit 66 and the warning determination unit 68 are one of the determination units provided in the ECU 40 that execute the lane change determination and the warning determination described later.
Further, the ECU 40 is provided with a rolling compaction number management unit 60 that manages the number of rolling compactions based on the calculation by each calculation unit and the determination unit, the determination result, the information recorded in the recording unit 52, and the like.

With reference to FIG. 4, an explanatory diagram of the compaction work is shown. Further, referring to FIG. 5, a flowchart showing a routine for controlling the number of rolling compactions of the rolling compaction machine according to the present invention, which is executed by the rolling compaction number management unit 60 of the ECU 40, is shown in the flowchart. Further, with reference to FIG. 6, an explanatory diagram for explaining the determination procedure of the folding determination unit 62 is shown. Hereinafter, the rolling compaction frequency management control procedure will be described with reference to FIGS. 4 to 6.
Hereinafter, for convenience of explanation, the compaction work in the entire section (section F) to be constructed is referred to as rolling compaction work.

According to FIG. 4, in the compaction work of the section F using the machine body 1, the section F is divided into a plurality of lanes such as the first lane, the second, ... Nth lane in advance, and the section F is tightened, for example, eight times per lane. Perform the hardening work. That is, in the compaction construction, the machine body 1 reciprocates four times per lane. Hereinafter, the compaction work in one outward trip or one return trip is referred to as rolling compaction work.

According to FIG. 5, this routine starts when the rolling compaction start button 23 is pressed (step S1). At this time, the value displayed on the counter 21 is set to 0, and the number of times of rolling pressure N, which will be described later, is also set to 0.

In step S10, the distance (rolling distance Ln) and, for example, the average speed at which the machine body 1 has performed the rolling work (hereinafter referred to as the current rolling work) at this time based on the mileage calculated by the rolling distance calculation unit 42. The measurement of (rolling speed Vn) is started and the process proceeds to step S20. The rolling speed Vn may be the maximum speed in the current rolling work.

In step S20, it is determined whether or not the folding back determination unit 62 has determined that the operator has switched the traveling direction of the machine body 1 in the front-rear direction.
According to FIG. 6, when the aircraft 1 advances on the current lane from one end side (position P1) of the lane (hereinafter referred to as the current lane) where the current rolling work is performed and the rolling work is performed, the other end of the current lane is performed. Reach the side (position P2). Upon reaching the position P2 in this way, the operator switches the traveling direction of the machine 1 to the rear in order to finish the current rolling work and perform the next rolling work in the current lane.

That is, the turn-back determination unit 62 determines that the operator has switched the traveling direction of the machine 1 in the front-rear direction when the forward / backward lever 11 is operated to switch the traveling direction of the machine 1. Further, even when the rolling compaction work is performed by moving backward on the current lane and the traveling direction of the aircraft 1 is switched forward, it is determined that the traveling direction of the aircraft 1 in the front-rear direction is switched in the same manner as described above.
Step S20 is repeatedly executed until it is determined that the determination result is true (Yes) and the operator has switched the traveling direction in the front-rear direction of the machine 1, and when the determination result is true (Yes), the process proceeds to step S30.

In step S30, it is determined whether or not the number of times the rolling compaction work in the current lane is completed (the number of existing rolling compactions N) recorded in the recording unit 52 is 0. When it is determined that the determination result in step S30 is true (Yes) and the number of times of rolling compaction N is 0, that is, it is determined that the current rolling compaction work is the first rolling compaction work in the current lane, the process proceeds to step S40, and in step S10. The measured value of the rolling compaction distance Ln at which the measurement is started is recorded in the recording unit 52 as the length of the current lane (set distance Lm), and the process proceeds to step S60.
On the other hand, if it is determined that the determination result in step S30 is false (No) and the number of times of rolling pressure N is 1 or more, the process proceeds to step S50. Hereinafter, steps S50 to S70 are construction requirements determined by the construction requirement determination unit 64, for example, determined based on a test construction performed in advance of road construction.

In step S50, whether or not the rolling compaction distance Ln exceeds the value obtained by multiplying the set distance Lm by, for example, 0.7 (predetermined ratio), that is, whether or not 70% of the rolling compaction work in the length of the current lane is completed. To determine. Note that the position P3 in FIGS. 4 and 6 is a position corresponding to the distance obtained by multiplying the set distance Lm by 0.7 from the position P1.

If it is determined that the determination result in step S50 is false (No) and the rolling distance Ln is equal to or less than the value obtained by multiplying the set distance Lm by 0.7 (positions P3 in FIGS. 4 and 6), the process proceeds to step S80 to be described later. The addition value A used in step S100 is set to 0. Further, when it is determined that the determination result in step S50 is true (Yes) and the rolling distance Ln exceeds the value obtained by multiplying the set distance Lm by 0.7, the process proceeds to step S60.

In step S60, it is determined whether or not the rolling compaction speed Vn for which the measurement was started in step S10 is equal to or less than the speed (speed limit Vlim) determined based on, for example, the test construction performed in advance of the road construction. The speed limit Vlim may be arbitrarily set by the operator.
If the determination result in step S60 is false (No) and it is determined that the rolling speed Vn exceeds the speed limit Vlim, the process proceeds to step S80 and the addition value A is set to 0. Further, when it is determined that the determination result in step S60 is true (Yes) and the rolling speed Vn is equal to or less than the speed limit Vlim, the process proceeds to step S70.

In step S70, it is determined whether or not there was sudden acceleration / deceleration during the current rolling compaction work. As this determination, for example, when the acceleration of the machine 1 is calculated based on the speed of the machine 1 calculated by the rolling speed calculation unit 44, and the maximum value of this acceleration during the current rolling work exceeds a predetermined acceleration, It is determined that there was sudden acceleration / deceleration (true (Yes) as a determination result). It may be determined that there was sudden deceleration (rapid acceleration / deceleration) when the brake pedal 33 was depressed during the current rolling operation, and the amount of change in the pressing amount of the accelerator pedal 31 was during the current rolling operation. It may be determined that there is sudden acceleration (rapid acceleration / deceleration) when a certain amount of change is exceeded.

If the determination result in step S70 is true (Yes) and it is determined that there has been sudden acceleration / deceleration during the current rolling compaction operation, the process proceeds to step S80 and the addition value A is set to 0. Further, when it is determined that the determination result in step S70 is false (No) and there is no sudden acceleration / deceleration during the current rolling compaction operation, the process proceeds to step S90 and the addition value A is set to 1.

After the addition value A is set to 0 or 1 in step S80 or step S90, in step S100, the value obtained by adding the addition value A to the existing rolling pressure number N is set as the recording number (addition number) X, and the process proceeds to step S110. The recording number X is recorded again in the recording unit 52 as the existing rolling number N, the process proceeds to step S120, the counter 21 displays the existing rolling number N, and the process returns to step S10 (return).

Therefore, in step S20 and step S30, it is determined that the current rolling compaction work is completed when the forward / backward switching operation is performed (step S20), and the number of rolling compaction work in the current lane is determined. It can be determined (step S30).

Here, if it is determined that the current rolling compaction work was the first rolling compaction work in the current lane (Yes in step S30), the rolling compaction speed Vn (measurement started when the rolling compaction start button 23 is pressed) ( When the speed limit Vlim is exceeded in steps S1 and S10 (No in step S60) or when there is a sudden acceleration / deceleration during the current rolling compression work (Yes in step S70), the current rolling compression work is performed correctly. It is determined that this is not the case, and the addition value A is set to 0 (step S80).

On the other hand, when the rolling speed Vn is equal to or less than the speed limit Vlim (Yes in step S60) and there is no rapid acceleration / deceleration during the current rolling work (No in step S70), the current rolling work was performed correctly. It is determined that the value is one, and the added value A is set to 1 (step S90).

As a result, in steps S100 to S120, if the current rolling work is not performed correctly, in other words, the rolling work does not satisfy the construction requirements, the current rolling work is included in the existing rolling number N. Since it should not be, 0 can be displayed on the counter 21 while the number of times of rolling pressure N is set to 0. Further, when the current rolling compaction work is performed correctly, in other words, if the rolling compaction work satisfies the construction requirements, the number of existing rolling compactions N can be set to 1 and displayed as 1 on the counter 21. ..

If it is determined that the current rolling work was the second and subsequent rolling work in the current lane (No in step S30), the rolling compaction started from the time when this routine was completed up to step S120 (return). When the distance Ln (step S10) is equal to or less than the value obtained by multiplying the set distance Lm by 0.7 (No in step S50), when the rolling speed Vn exceeds the limit speed Vlim (No in step S60), and the current rolling pressure. When there is a sudden acceleration / deceleration during the work (Yes in step S70), it is determined that the current rolling compression work has not been performed correctly, and the added value A is set to 0 (step S80).

Here, since the set distance Lm uses the rolling distance Ln measured in the first rolling operation and recorded in the recording unit 52 (step S40), the operator inputs the set distance Lm for each lane. You can save the trouble of doing it.
As a result, in steps S100 to S120, if the current rolling work is a rolling work that does not satisfy the construction requirements, the current rolling work should not be included in the existing rolling number N, and therefore the existing rolling number of times. The value of the number of already rolled times N can be displayed on the counter 21 without changing N. If the current rolling work is a rolling work that satisfies the construction requirements, 1 can be added to the existing rolling number N and the counter 21 can display a new value of the existing rolling number N. ..

Further, regarding the above construction requirements (steps S50 to S70), since the construction requirement determination unit 64 is provided, the current rolling compaction work satisfies the requirements determined based on the test construction performed in advance of the road construction. It can be determined whether or not the work was pressure work.

With reference to FIG. 7, a flowchart showing a routine for determining the lane change of the compaction machine according to the present invention, which is executed by the lane change determination unit 66 of the ECU 40, is shown. Further, referring to FIG. 8, as an example of the steering operation, a graph showing the correlation between the steering angle R and time and an explanatory diagram showing the state of the corresponding aircraft 1 are shown. Hereinafter, the lane change determination procedure will be described with reference to FIGS. 7 and 8.

In step S200, it is determined whether or not the steering angle (hereinafter referred to as steering angle R) calculated from the steering operation information by the operator input from the steering angle sensor 13a is equal to or greater than a predetermined angle. When the determination result in step S200 is false (No) and the steering angle R is less than a predetermined angle (state A in FIG. 8), this routine is terminated (returned), and the process proceeds to step S200 again. Further, when the determination result in step S200 is true (Yes) and the steering angle R is equal to or greater than a predetermined angle, the process proceeds to step S210.

That is, in step S200, it is determined whether or not the operator has operated the steering 13 for lane change, and when it is determined that the steering angle R is equal to or greater than a predetermined angle, steering for lane change is determined. It is determined that the operation has been performed, and the process proceeds to step S210.

In step S210, it is determined whether or not the elapsed time from the determination that the steering angle R is equal to or greater than the predetermined angle has elapsed a predetermined time. When it is determined that the determination result in step S210 is true (Yes) and the specified time has elapsed, the rolling compaction number management control is terminated. Further, if it is determined that the determination result in step S210 is false (No) and the specified time has not elapsed, the process proceeds to step S220.

In step S220, it is determined whether or not the steering angle R is 0 degrees. If it is determined that the determination result in step S220 is false (No) and the steering angle R is not 0 degrees, the process returns to step S210. Further, when it is determined that the determination result in step S220 is true (Yes) and the steering angle R is 0 degrees, the process proceeds to step S230.

That is, in step S210 and step S220, when the steering angle R becomes 0 degrees within the specified time (step S210), the process proceeds to step S230, and the steering angle R becomes 0 degrees within the specified time (step S210). If this is not the case, it is determined that the aircraft 1 is not changing lanes, but is, for example, trying to move to a distant place, and the rolling compaction number management control is terminated (states B and C in FIG. 8).

In step S230, it is determined whether or not the elapsed time from the determination that the steering angle R is 0 degree has elapsed, as in step S210. When it is determined that the determination result in step S230 is true (Yes) and the specified time has elapsed, the rolling compaction number management control is terminated. Further, if it is determined that the determination result in step S230 is false (No) and the specified time has not elapsed, the process proceeds to step S240.

In step S240, it is determined whether or not the steering angle R is in the direction opposite to the predetermined angle and is equal to or greater than the predetermined angle (opposite angle). Here, the opposite angle means, for example, an angle at which a predetermined angle is steered 15 degrees to the right of the airframe and then steered 15 degrees to the left of the airframe. If the determination result in step S240 is false (No) and the steering angle R is less than the opposite angle, the process returns to step S230. Further, when the determination result in step S240 is true (Yes) and the steering angle R is equal to or greater than the opposite angle, the process proceeds to step S250.

That is, in step S230 and step S240, when the steering angle R becomes an angle equal to or greater than the opposite angle within the specified time (step S230), the process proceeds to step S250, and the steering angle R becomes (step S230) within the specified time. When the angle does not exceed the opposite angle, it is determined that the aircraft 1 is not a lane change, and the rolling compaction number management control is terminated (state D in FIG. 8).

Since step S250 and step S260 are the same as steps S210 and S220, the description thereof is omitted here. If the steering angle R does not reach 0 degrees within the specified time (step S250), it is determined that the aircraft 1 is not changing lanes, but is, for example, trying to move to a distant place, and the number of rolling compactions is managed. The control is terminated (state E in FIG. 8).

Further, when it is determined that the determination result of step S260 is true (Yes) and the steering angle R is 0 degrees and the process proceeds to step S270, the number of times of rolling pressure N is set to 0 and the process proceeds to step S280, and the counter 21 Displays the number of times of rolling compaction N (0 times) and returns to step S200 (return).

By the way, in general, the airframe 1 is compacted a certain number of times (the number of registrations described later) for the current lane, and in other words, is compacted to the position P2 or the position P1 and then is moving forward or backward. Change the lane.

Here, returning to FIG. 5, if the lane change is replaced with the rolling compaction number management control flow executed by the rolling compaction number management unit 60, the lane change is performed while step S20 is repeated until the determination result in step S20 becomes true (Yes). Will be done. That is, when the lane change determination unit 66 determines that the machine 1 has changed the lane and sets the already rolled number N to 0, the already rolled number N is reset to 0 before shifting to step S30. ..

By resetting the existing rolling number N to 0 before shifting to step S30 in this way, the rolling number management control flow is the same as when the first rolling work is completed in the first lane. Will be advanced.
As a result, when the machine 1 changes lanes, the count of the number of compaction operations is reset regardless of the operator's operation, so when the operator changes lanes, the operator forgets to reset the count of the number of compaction operations. It is possible to prevent the count from being reset.

Referring to FIG. 9, a flowchart showing a routine for warning determination control procedure of the compaction machine according to the present invention, which is executed by the warning determination unit 68 of the ECU 40, is shown. Hereinafter, the warning determination control will be described with reference to FIG. 9.

In step S300, it is determined whether or not the operator operates the rolling compaction number setting button 25 to register the rolling compaction number per lane. If it is determined that the determination result in step S300 is false (No) and the number of rolling compactions is not registered, this routine is terminated. Further, if it is determined that the determination result in step S300 is true (Yes) and the number of rolling compactions is registered, the process proceeds to step S310.

In step S310, it is determined whether or not the existing rolling number N is a value obtained by subtracting 1 from the registered rolling number (hereinafter referred to as registration number C). When it is determined that the determination result in step S300 is true (Yes) and the number of times of rolling compaction N is a value obtained by subtracting 1 from the number of registrations C, the process proceeds to step S320, for example, a warning mode A in which a buzzer sounds once. The notification mode) is sounded from the speaker 27 to end this routine. Further, if it is determined that the determination result in step S300 is false (No) and the existing rolling pressure number N is not a value obtained by subtracting 1 from the registration number C, the process proceeds to step S330.
This allows the operator to recognize that the lane should be changed after the current rolling compaction work is completed.

In step S330, it is determined whether or not the value of the existing rolling number N is equal to or greater than the value of the registration number C. If it is determined that the determination result in step S330 is true (Yes) and the value of the number of rolling compactions N is equal to or greater than the value of the number of registrations C, the process proceeds to step S340, for example, a warning mode B (notification) in which a buzzer sounds twice. Aspect) is sounded from the speaker 27 to end this routine. Further, if it is determined that the determination result in step S330 is false (No) and the value of the existing rolling number N is less than the value of the registration number C, the process proceeds to step S350.
This allows the worker to recognize that the lane should be changed promptly.

In step S350, the lane change determination unit 66 determines whether or not the aircraft 1 has changed lanes. When it is determined that the determination result in step S350 is true (Yes) and the aircraft 1 has changed lanes, the process proceeds to step S360, and a warning mode C (notification mode) for sounding a buzzer sound, for example, is sounded from the speaker 27. End the routine. If it is determined that the determination result in step S350 is false (No) and the aircraft 1 has not changed the lane, the routine ends without any warning (notification).

As a result, the operator can recognize that the number of rolling compaction operations in the original lane is insufficient and the operator should promptly return to the original lane. On the other hand, when No in step S350, the value of the number of rolling compactions N is less than the value of the number of registrations C (step S330), and the machine 1 has not changed the lane, in other words, the worker is in the current lane. No warning is given as it is the time when the compaction work is being continued.

Therefore, the warning determination control by the warning determination unit 68 can urge the operator to change the lane at an appropriate time.

As described above, in the rolling machine according to the present invention, the rolling compaction machine 1 is recorded in the recording unit 52 and the recording unit 52 for recording the number of times of rolling compaction N, which is the number of rolling operations per lane performed by the machine body 1. In the machine 1 equipped with a counter 21 that displays the number of times of rolling compaction N and notifies the operator of the number of times of rolling work, and a forward / backward lever 11 that detects the forward / backward operation of the machine 1 by the worker. It has a turn-back determination unit 62 for determining whether or not the traveling direction in the front-back direction of 1 has been switched, and a rolling compaction number management unit 60 for managing the existing rolling pressure number N, and the turning-back determination unit 62 advances forward and backward. When it is detected that the traveling direction of the machine 1 in the front-rear direction has been switched by the lever 11, it is determined that the traveling direction of the machine 1 in the front-rear direction has been switched, and the rolling compaction number management unit 60 determines from the turn-back determination unit 62 that the traveling direction of the machine 1 has been switched. When it is determined that the traveling direction of 1 has been switched, 1 is added to the number of times of rolling pressure N recorded in the recording unit 52.

Therefore, when it is determined that the traveling direction of the machine 1 in the front-rear direction is switched when the forward / backward operation of the machine 1 by the operator is detected by the forward / backward lever 11, the machine 1 performs the rolling work per lane by 1. Since it was determined that the product had been turned and the recording number X obtained by adding 1 to the existing rolling pressure number N was recorded in the recording unit 52 as the existing rolling pressure number N, the operator counted the existing rolling pressure number N. The number of times of rolling pressure N can be automatically counted without any operation.

Then, the construction requirement determination unit 64 for determining whether or not the compaction work by the machine body 1 satisfies the predetermined construction requirements is provided, and the compaction frequency management unit 60 is subjected to the compaction work by the construction requirement determination unit 64. Only when it is determined that the construction requirements are satisfied, 1 is added to the number of times of rolling pressure N recorded in the recording unit 52.
Therefore, the construction requirement determination unit 64 determines whether or not the rolling work meets the construction requirements, and counts the existing rolling number N only when it is determined that the rolling work meets the construction requirements. It is possible to improve the construction accuracy by counting only the rolling work that meets the construction requirements.

In particular, the rolling compaction distance calculation unit 42 for calculating the rolling compaction distance Ln is provided, and in the construction requirement determination unit 64, the rolling compaction distance Ln calculated by the rolling compaction distance calculation unit 42 is larger than a predetermined ratio of the length of the current lane. At this time, since it is determined that the construction requirements are satisfied, the rolling work that does not meet the construction requirements such that the existing rolling number N is insufficient for a specific position is excluded from the count of the existing rolling times N. be able to.

Further, since the rolling distance calculation unit 42 calculates the length of the lane when the rolling work is first performed on the current lane (step S10 and step S40), for example, it is necessary to separately measure the construction distance, or an operator. It is possible to save the trouble of inputting the construction distance by manually inputting.

Then, a rolling speed calculation unit 44 for calculating the rolling speed Vn is provided, and the construction requirement determination unit 64 is required to perform the construction when the rolling speed Vn calculated by the rolling speed calculation unit 44 is equal to or less than the speed limit Vmin. Since it is determined that the vehicle is equipped with the above, the compaction work that does not meet the construction requirements, such as when the compaction work is performed at a speed faster than the speed determined based on the test construction performed in advance of the road construction, has already been performed. It can be excluded from the count of the number of pressures N.

Then, a lane change determination unit 66 for determining whether or not the aircraft 1 has changed lanes from the current lane to an adjacent lane is provided, and the existing rolling pressure number N determination unit is a lane adjacent to the aircraft 1 by the lane change determination unit 66. When it is determined that the lane has been changed to, the number of times of rolling pressure N recorded in the recording unit 52 is set to 0.

Therefore, when the lane change determination unit 66 determines that the aircraft 1 has changed lanes to the adjacent lane, the existing rolling pressure number N recorded in the recording unit 52 by the existing rolling pressure number N determination unit is set to 0. It is possible to automatically reset the already rolled number of times N without the operator performing a counting operation of the already rolled number of times N.

Further, a steering angle sensor 13a for detecting the steering angle related to the steering operation of the aircraft 1 by the operator is provided, and the lane change determination unit 66 calculates the steering angle and the rolling speed calculated by the steering angle sensor 13a. Based on the correlation with the rolling speed Vn calculated by the unit 44, it is determined whether or not the machine 1 has changed lanes from the lane in which the rolling work is performed to the adjacent lane.

Therefore, it is determined whether or not the aircraft 1 has changed lanes from the current lane to the adjacent lane by the correlation between the steering angle calculated by the steering angle sensor 13a and the rolling speed Vn calculated by the rolling speed calculation unit 44. Therefore, it is possible to improve the accuracy of determining whether or not the aircraft 1 has changed lanes from the lane where the rolling compaction work is performed to the adjacent lane.

Further, the counter 21 includes a rolling compaction number setting button 25 for inputting the number of scheduled rolling compaction operations per lane, and the counter 21 has the existing rolling compaction number N recorded in the recording unit 52 as the rolling compaction number setting button 25. When the number of registrations C entered by is exceeded, the warning mode A, B, and C are used to warn the worker as a mode different from the notification mode when the number of already rolled times N is notified to the worker. , It is possible to improve the work efficiency by suppressing the rolling work more than necessary.

In particular, the counter 21 is when the number of times of rolling compaction N recorded in the recording unit 52 is less than the number of registrations C input by the number of rolling compaction number setting button 25, and the machine body 1 is adjacent by the lane change determination unit 66. When it is determined that the lane has been changed to the lane to be used, the worker is warned in the warning mode C, which is different from the warning modes A and B. Can be notified to the worker.

This concludes the description of the compaction machine according to the present invention, but the present invention is not limited to the above embodiment and can be changed without departing from the gist of the present invention.
For example, in the present embodiment, the machine body 1 has been described as a tire roller, but a macadam roller or a vibration roller for earthwork may be used, and a rolling machine may be used.

Further, in the present embodiment, the lane change determination is described by the correlation between the steering angle and the time, but the attitude of the aircraft 1 is determined using the speed of the aircraft 1 to determine whether or not the lane change has been performed. You may do so.

Further, in the present embodiment, as the warning modes A, B, and C, the buzzer sound is sounded once, twice, or five times, but it may be an announcement by voice or an announcement by light using a lamp or the like. ..
Further, in the present embodiment, it is determined in steps S50 to S70 whether or not the construction requirements are satisfied, but any one of the construction requirements may be included, and other construction requirements are included. May be good.
