Description

The present invention relates to a spraying work method for a liquid spraying vehicle.

(Prior Art) Generally, a liquid spraying vehicle for spraying water, a chemical solution, a chemical agent or the like onto a road surface is widely known. As such a liquid spraying vehicle, for example, there is a liquid spraying vehicle that sprays an antifreezing chemical liquid.However, spraying by the spraying vehicle is performed only on a specific place such as a bridge or the like where it is easy to freeze. ing.

(Problems to be solved by the invention) However, conventionally, in such a spraying vehicle, while the spraying location, spraying time, etc. are recorded in the work diary, the actual traveling state is searched by the tachograph. There is a problem in that it is not possible to grasp the details, although the outline can be grasped.

Further, Japanese Patent Laid-Open No. 59-96339 discloses a construction machine such as a power shovel that performs a single operation by sequentially performing a plurality of operations by a plurality of actuators, and various operations such as excavation work and slope finishing. Each operation of each operation lever for operating the above plurality of actuators is recorded in advance as one operation pattern, and when this operation pattern and a series of procedures by each operation lever match, which operation is performed? It is disclosed that the work is recognized and the work is recorded as being performed.

However, a construction machine such as a power shovel performs one operation by sequentially performing a plurality of operations by a plurality of actuators as described above. At
The work can be achieved as a result of operating the operation levers at any time, and the operation amount of each actuator (the operation amount of the operation lever) varies depending on the situation even in the same work. Therefore, even if a procedure for using each operation lever in one work is instructed to such a thing, when an operator who has no working experience operates it, all that is required is to know the operation lever to be operated next. There is a problem in that it is difficult to know how to operate the lever, and it is very time-consuming and inefficient to operate the operation lever according to each instruction.

And the present invention can perform the spraying work easily and accurately,
Moreover, it is an object of the present invention to provide a liquid spraying vehicle capable of easily managing and storing work records of spraying work.

(Means for Solving Problems) A spraying method for a liquid spraying vehicle according to the present invention is a vehicle that travels along a preset route, and a spraying start position and a spraying end position of a drug or the like are set during the running. The data is recorded as spraying instruction data in the memory of the spraying control unit based on the travel distance corrected as necessary, and the recorded spraying instruction data is transferred to the data recorder and recorded. The spraying instruction data recorded in the memory is transferred to the memory of the spraying control unit and read, and the spraying control unit corrects the spraying instruction data as necessary based on the spraying instruction data and displays it on the operation panel according to the traveling distance during the spraying work. The work instruction is issued, and the operator operates the operation lever according to the work instruction to perform the spraying work, and the spraying operation status is recorded in the memory of the spraying control unit as a work record. It is transferred to a data recorder and recorded.

It is supposed to be sprayed more.

FIG. 3 shows the operation panel 30, and FIG. 4 shows the block configuration of the application control section for performing application control. The application control section 50 controls the application operation based on the operation of the operation panel 30.

In the operation panel 30, reference numeral 32 is a time display section, and correction switches 32a and 32b are arranged on the lower side. Reference numeral 33 is a date display portion, and a set switch 33a is arranged on the lower side. Reference numeral 34 is a distance display unit, and a set switch 34a is arranged on the lower side. Reference numeral 35 is a selection switch for selectively selecting the teaching state and the actual traveling state.

36 and 37 are an A mode switch and a B mode switch, respectively. It should be noted that the A mode is for spraying on bridges, and the B mode is for spraying in so-called culverts (overpass areas, etc.).

Reference numerals 38 and 39 denote transfer lamps and transfer switches for indicating input / output of data to the data recorder 40, that is, a transfer state, and 41 denotes a connector for the data recorder 40. 42 is a spraying lamp that lights up when spraying is required.

On the other hand, the spray control unit 50 includes the interfaces 51 and 52 and the CPU5.
3. It consists of memory 54.

The CPU 53 has a distance signal from the tachometer 44 linked to the wheels 45, a correction signal from the correction switches 32a and 32b provided on the operation panel 30, and the set switch 3
The set signals from 3a and 34a, the mode signal from the A mode switch 36, and the mode signal from the B mode switch 37 are input via the input / output interface 51.

Then, the CPU 53 records the spraying work data in the memory 54 by teaching described later, instructs the actual spraying work based on the spraying work data, and records the data of the spraying work actually performed in the memory 54. To do.

The memory 54 is configured to be able to write and read data with the data recorder 40.

Next, a spraying work method according to the present invention, which is performed by the liquid spraying vehicle configured as described above, will be described.

First, the teaching operation for obtaining work instruction data will be described with reference to FIG.

First, in step S1, the engine of the liquid spraying vehicle 1 is operated to start traveling, and when the vehicle reaches a start point of a preset route, the distance display unit 34 is corrected to 0 km, and the set switch 34a below it is corrected. To operate.

Then, when traveling is continued and the spray start position is reached, A
After the mode switch 36 or the B mode switch 37 is operated, when the spraying end position is reached, the A mode switch 36 or the B mode switch 37 is operated again. As a result, the A mode switch 36 or the B mode switch is stored in the memory 54.
The operation signal from 37 is recorded together with the distance by the distance signal from the tachometer 44 (steps S2 to S5).

In this way, the operation of the A mode switch 36 or the B mode switch 37 is performed at a required place (each spraying place), and the route is traveled. In this case, the selection switch 35 is on the teaching side.

Further, an error occurs in the distance signal from the tachometer 44 due to a change in the running condition due to a tire idling due to a road surface freezing, so that it is necessary to correct the error in this distance. For example, in the case of an expressway, this modification uses a distance display post (usually set up every 100 m, hereinafter referred to simply as a distance post) that is installed on the side of the road. Specifically, the actual distance during work is calculated from the distance post, the distance is set in advance in the distance display unit 34, and the set switch 34a is set when the actual distance is passed.
By operating, the distance can be corrected to the regular distance (steps S6 and S7).

When the end of the route is reached in this way (step S
8) Travel and return to the garage, this time connect the data recorder 40 to the spray control unit 50 and press the transfer switch 39. In the spray controller 50, based on the operation signal from the transfer switch 39,
The work instruction data recorded in the memory 54 is transferred to the data recorder 40 via the CPU 53 (step S9). On this occasion,
The transfer lamp 38 of the operation panel 30 lights up, indicating that the transfer is in progress. When the transfer is completed, the transfer lamp 38 is turned off. After that, the connection of the data recorder 40 is released, the engine is stopped, and the teaching is completed.

Next, a case where the spraying work is performed based on the work instruction data obtained by the above-mentioned teaching will be described with reference to FIG.

First, the engine is started, the time display unit 32 and the date display unit 33 are adjusted, and the selection switch 35 is tilted to the actual traveling side (step S10).

Then, the tape on which the data is recorded by the teaching is set on the data recorder 40, and the data recorder 40
40 is connected to the spray controller 50. Then transfer switch 39
When is pressed, the work instruction data is recorded in the memory 54 of the spray control unit 50, and when the transfer lamp 38 is turned off upon completion of the transfer, the connection is released (step S11).

Then, the set switch 33a of the date display unit 33 is pushed. As a result, the date is recorded in the memory 54 (step S1
2).

Next, the vehicle is moved, and water is supplied into the liquid tank 5 toward the water supply station (step S13). At this time, the time when the vehicle starts moving and the time when the water is supplied are recorded in the memory 54 (step S14).

After that, set the distance display 34 to 0 km, head to the start point of the route where the teaching data was recorded, and press the set switch 34a when departing from this start point,
The vehicle is driven along the above route (step S15).

As the vehicle travels, the distance signal from the tachometer 44 is input to the CPU 53 of the spray control unit 50, and the CPU 53 compares the distance signal with the teaching data of the memory 54, and the distance based on this distance signal reaches the spray start position. Then, the spraying lamp 42 is turned on, and the operator operates the operation levers 17a and 17b to start the spraying operation by turning on the spraying lamp 42 (steps S16 to S18).

Then, when the distance signal from the tachometer 44 reaches the spraying end position according to the teaching data, the spraying lamp 42 is turned off, and by turning off the spraying lamp 42, the operator operates the operation levers 17a, 17b to end the spraying work. (Steps S19-S21). The time of this spraying work is recorded in the memory 54 (step S22).

As in the case of teaching, there is an error in the distance signal from the tachometer 44 depending on the driving situation.Therefore, if you want to correct the error of this distance, you can use the distance post standing on the side of the road in the middle of spraying. The calculated actual distance is set on the distance display unit 34, and the set switch 34a is pressed at the moment when the set position is passed, so that the corrected distance is recorded regardless of the signal from the tachometer 44 ( Steps S23, S24).

In this way, when the end point of the predetermined route is reached (step S25), the spraying work is completed and the vehicle is returned to the garage.
The work record is transferred to and recorded on the cassette tape using 40 (step S26).

The work record data recorded on the cassette tape can be analyzed using, for example, an office computer (step 27).

In the above embodiment, there are two types of mode modes, A mode and B mode, but it is needless to say that the mode can be provided if there are other working conditions.

Further, in the above embodiment, the teaching (preliminary plan) is performed by the preliminary traveling, but it may be conducted by the survey on the map or the like.

Furthermore, in the embodiment, an independent engine was used as the drive source of the spray pump, but the power of the vehicle engine was changed to PTO.
The variable discharge pump may be driven via the shaft, and the liquid dispersion pump may be driven by a hydraulic motor operated by the pressure oil.

(Effects of the Invention) As described above, according to the present invention, a vehicle travels along a preset route, and during this traveling, the spraying start position and spraying end position of a drug or the like are corrected as necessary. By recording as spraying instruction data in the memory of the spraying control unit based on the traveling distance, accurate spraying instruction data can be obtained regardless of the traveling situation. Since the spraying work is performed according to the traveled distance that has been corrected in accordance with the above, the spraying work can be performed accurately, and the operator only has to operate the operation lever according to the work instruction displayed on the operation panel. The spraying work can be easily performed according to the work instruction. Further, by transferring the work record to the data recorder and recording the work record, the work record can be easily managed and stored.
