DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle mounted on a transport vehicle such as a dump truck and a loading machine such as a rotary snowplow, and how many times the dump truck carries out loading and unloading when carrying snow and earth and sand. The transport vehicle records the individual information on a magnetic card by a magnetic card recording device attached to each vehicle. In addition, the loading machine stores information such as the number of times of transportation by ID code (unique number attached for identification) of the entire transported vehicle that has been loaded into an external recording device such as a snowplow construction recording device disclosed in Japanese Patent No. 1873334. The present invention relates to a transport work execution recording device which records the transport work amount and the like so that the transport amount and the like can be easily grasped.

[0002]

2. Description of the Related Art Heretofore, this type is as follows. When transporting snow, earth and sand loaded on a dump truck using a rotary snowplow, shovel car, belt conveyor, etc., personnel are assigned to that location to carry in or unload the snow, earth and sand loaded on the dump truck. Each time a dump truck is used, the name of the trader, the car number, etc. are entered in a record book, the number of times the dump truck has performed the action has been grasped, and the transport amount is calculated by multiplying the number of times by the load amount. Further, as another embodiment, an electric signal from a sensor attached to a dump lever portion operated by an operator so as to be able to detect that the lever has been operated, and a dump signal, A tachograph attached to a truck (an instrument that automatically records the instantaneous running status of a car) combines a speedometer and a clock to make it possible to attach recording paper to a clock mechanism. It rotates in the same direction in synchronization with the movement of. A recording needle with a sapphire pen comes in contact with the recording paper, and the instantaneous instantaneous speed, traveling distance, traveling time, etc. according to the operation of the car are continuously recorded through a tachograph drive shaft. It is required to be installed by the Road Transport Vehicles Act (enforced from September 1, 1967), etc., and uses the equipped electromagnetic recording needle to grasp as follows.

When the operator of the dump truck operates the dump lever to lower the loaded snow, earth and sand, a signal of a sensor for detecting that the dump lever has been operated is transmitted.
When it is input to the electric coil that composes the electromagnetic recording needle through a device that converts it into an electric signal that is interrupted for a certain period of time, it becomes an electromagnet, and the movable iron piece with the recording needle becomes a blinking operation that performs suction return, and contacts the recording paper The recording needle is repeatedly moved up and down, so that a solid (square) recording is obtained on the recording paper. A timer is incorporated in the device for converting to an electric signal, and after a certain period of time, the operation is stopped and the recording of the filling is not performed, and the same operation is repeated again when the next sensor signal is input. On the recording paper, a record of the paint over time is obtained, and the number of paints is read to judge the number of times, and the carry amount is calculated by multiplying the load amount.

In recent years, with the development of electronic equipment, mechanical recording is not performed on tachograph recording paper.
A device for performing digital recording on a data recording medium such as a C card is attached to a dump truck to record an operation state,
The data recorded on a data recording medium such as a C card is analyzed and processed by a personal computer or the like, and the transport amount for one vehicle is calculated by multiplying the number of transport times by the load amount. And the total transported amount was determined.
The dump truck supplier charges the transportation requester (for example, the loading company) for the transportation cost based on the requested transport amount, and the transportation requester also confirms the requested transportation cost. He needed something that would remain accurate.

[0005]

According to the prior art, a place for carrying snow, earth and sand, etc.,
In addition, there is a problem that the number of persons to be recorded must be arranged at the loading place, and the number of times entered in the record book differs from the number of times reported by the dump truck supplier due to a recording error or the like. In addition, mechanical recording on the tachograph recording paper can be performed by operating the dump lever even when the tachograph is not loaded. There were models without a recording needle, and there was a problem with the difficulty of handling. In such a case, there has been a problem that it is not possible to accurately grasp / confirm the transport amount and bill / pay the transport cost. Further, in the case of a data recording medium such as an IC card, the number of times cannot be directly read by itself, and a secondary processing analysis process must be performed by a personal computer or the like. Otherwise, the entire transport amount cannot be obtained, so that labor is saved. However, when the number of units increases, there is a problem that the analysis process takes time.

The present invention has been made in view of such problems of the prior art, and has as its object to provide the following. The present invention takes advantage of the work property that the loading machine and the transport vehicle approach a short distance during loading, and the transport vehicle moves away from the loading vehicle when loading is completed. Weakness is determined by the communication condition of the radio waves, and the portable type is easy to carry, such as an IC card. It can perform digital recording with high reliability of data, perform magnetic recording and print recording on a magnetic card that can print data contents and check it visually, and can read the number of times visually, Secondary processing can also be performed, and furthermore, a snowplow construction recording device attached to a loading machine such as a rotary snowplow can record the operation status of the loaded vehicle and the overall operation. There is provided a carrying works construction recording apparatus makes it possible to grasp at once the amount.

[0007]

FIG. 1 shows a basic construction diagram of a transportation work execution recording apparatus according to the present invention for achieving the above object. On the transport vehicle side, as shown in the basic configuration diagram of FIG. 1, data communication is performed between the transport vehicle and the loading machine by wireless communication means A using weak radio waves that can reach only a very short distance. The loading / unloading / unloading information storage means C which recognizes the loading by the loading state detecting means B which determines loading based on the communication state, stores the date and time and records the time of loading / unloading, and the storage thereof. Magnetic card recording means D for recording the recorded information on the magnetic card E by the magnetic card recording device.

On the loading machine side, as shown in the basic configuration diagram of FIG. 1, the ID code of the transporting vehicle obtained by the wireless communication means A and the loading state detecting means B is recorded on a snowplow construction recording device attached to the loading vehicle. And a construction recording device ID code recording means F for recording the data as time-series data in the G internal storage element. In the above configuration, the transport vehicle and the loading machine exchange information with each other by means for performing operations related to each other. The entire information can be recorded on the magnetic card E
Is processed by a processing device such as a computer, whereby information such as the number of times of transportation can be known. In addition, since the number of times can be known also by printing recorded on the back surface of the magnetic card, the number of times of transportation can be immediately grasped without performing analysis processing by a processing device such as a computer. Although the snowplow construction recording device G originally records the operation status of the loading vehicle, it can also record the number of times the accompanying transportation vehicle has been transported, and by processing the data together with the operation data of the loading machine. Very good results are obtained in terms of management. When only one of the transporting vehicle and the loading machine is required to be recorded, unnecessary recording means can be set as an option, and additional recording can be performed later.

[0019]

Since the present invention is configured as described above, it has the following effects. The present invention uses a wireless communication means to determine a loading state between a transport vehicle and a loading machine, stores a loading completion signal from the loading machine, and then outputs a sensor signal for detecting that the dump lever has been operated. Therefore, the reliability of the data became very high because it recognized and recorded that it was unloaded for the first time. Further, since a magnetic card is used as the data recording medium, processing can be performed by two methods: computer analysis using magnetic recording, and visual counting using print recording.

When magnetic recording is used, processing machines (personal computers, printers, magnetic card readers / writers, peripheral devices, etc.) and processing software must be prepared, but computerization of business processing is progressing. By simply preparing processing software and peripheral devices (such as a magnetic card reader / writer), consistent slip processing can be performed. In the case of visual observation, there is no need to perform an analysis process, so that the cost of a processing machine and the time required for the analysis are unnecessary, and the number of times of transportation can be immediately grasped by printing on the back surface. In addition, the snowplow construction recording device attached to the loading machine also records the number of times of transportation for all vehicles, so it is possible to simultaneously process the loading status of the loading machine and grasp the amount of transportation at the same time. Above became very convenient.

Recording on the transport vehicle side and recording on the loading machine side can be performed, and processing can be performed in all three methods. There is a degree of freedom in processing selection, and other than the selected recording method, an option setting is added later as an option setting. Because it can be introduced, it is feasible and cost-effective. By using the present invention made in this way, it is possible to perform accurate recording without human error, prevent unauthorized recording, select a processing method, and develop the system in the future. Data management for each ID code can be easily performed, and business operations such as grasping and confirming the amount of transportation and billing / payment of transportation costs can be performed smoothly, and very convenient and good results can be obtained.
