Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device that automatically records intermittent transportation work using an automobile or the like.

In general, in the construction work of Rockfill dams, etc., a method is adopted in which construction is carried out by using a large dump truck or the like to collect various rough stones from a pile of rough stones.

It goes without saying that during this work, it is necessary to know what kind of rough stones and how many tons were transported to the dam from the standpoint of quality, quality, cost calculation, etc.

However, accurately grasping the above information is technically difficult and a laborious task.

In other words, because the transportation by dump trucks is contracted out to subcontractors, the types of vehicles are not fixed, and the same vehicles make multiple round trips a day. I stopped the car and read the company name,
The method used is to check the vehicle number, model, type of cargo, weight measurement, etc. each time the vehicle passes.

However, as the number of gates increases, this method inevitably becomes more complicated to check, is inefficient, and is not easy to aggregate data.

In addition, there is an artificial checking operation that requires stopping the vehicle and checking each time.
This method has the drawback of requiring a large amount of effort and time when checking a large number of vehicles or collecting information, which is extremely inconvenient when centrally managing transportation operations, and a solution to this problem has long been desired. However, there is still no accurate and easy method.

In view of the above points, the present invention has been made to solve such problems and eliminate such drawbacks.The purpose of the present invention is to accurately and centrally manage intermittent transportation work using automobiles, etc. An object of the present invention is to provide an automatic transportation work recording device that can perform quickly, save labor, and automatically perform concentrated work.

In order to achieve such an objective, the present invention provides a shipping, receiving, and

This weight scale calculator 8 constitutes a weight detection means that detects the difference between the weight of the dump truck 2 and the empty weight of the dump truck 2 based on the weight information from the weight scale sensor 7, and detects an information signal corresponding to the net loaded weight. are doing.

A computer function that decodes various information such as vehicle number, vehicle type, empty vehicle weight, and number of axles according to a predetermined procedure from the light reception signal captured by the light receiving unit 6, a clock device necessary for time management, and a weighing scale. A function that sends an empty vehicle weight signal necessary for calculating the net loaded weight from the loaded weight of the vehicle measured by the calculator 8 to the weighing scale calculator 8, and net loaded weight information from the weighing scale calculator 8 and the above-mentioned information. The function is to organize and integrate the various information decoded by the computer that decodes the information and type it out on a printing machine along with the time information from the clock device, and at the same time as this type-out, a verification completion signal is sent to a separate display board to be described later. This sub-control unit has a function of transmitting the integrated signals to a computer, which will be described later.

10 is a printing tape typed out from the printing machine of the sub-control unit 9; 11 is a display board that informs the driver of the dump truck 2 that the verification has been completed by the output of the sub-control unit 9; and 12 is a display board that displays information from the sub-control unit 9. This is a transmission circuit for transmitting data to the computer 13 in the management room.

Next, the operation of the embodiment shown in this figure will be explained.

First, when the site supervisor sets, for example, rough stone A, vehicle number 25, and empty weight B using the setting switch 4 of the dump truck 2 and locks it, the type display section 3 provided on the front of the dump truck 2
The indicator light turns on R1.

At the same time, the light emitting unit 5 stores the set code, for example, vehicle number 25, raw stone A, empty vehicle weight B,
Light is emitted according to a predetermined order.

Also, since there are both two-axle and three-axle types of vehicles, it is absolutely necessary to determine whether the vehicle has two axles or three axles when calculating the weight.

Therefore, for example, the relationship between the vehicle number and the number of axles is set in advance such that vehicle numbers 20 to 30 are two-axle vehicles and vehicle numbers 31 to 40 are three-axle vehicles.

Next, the dump truck 2 loads the designated rough stones at a predetermined location, departs toward a predetermined destination, and passes in front of the light receiving section 6.

At this time, the light emitted from the light emitting section 5 is received by the light receiving section 6, photoelectrically converted, and the electrical signal is sent to the sub-control section 9.

As mentioned above, the sub-control unit 9 has a built-in clock device, a calculator, etc., and decodes the input from the light receiving unit 6 to determine the vehicle number 2.
5. Output information such as empty vehicle weight B, loaded raw stones A, and number of axles 2.

At the same time, the weight scale calculator 8 displays the empty vehicle weight B and the number of axles 2.
Provide information that is.

That is, since the storage unit of the computer of the sub-control unit 9 has previously stored that vehicle numbers 20 to 30 have two axles, it is determined that vehicle number 25 has two axles and outputs it.

Then, the sub-control unit 9 instructs the weighing scale calculator 8 that the empty vehicle weight B and the number of axles are "2", and the weighing scale calculator 8 instructs the weighing scale calculator 8 to indicate that the weighing scale sensor T is connected to the first axle. and the weight detection outputs of the second axle are added, and the empty vehicle weight is further subtracted to output the net loaded weight, which is input to the sub-control unit 9.

When the dump truck 2 advances and reaches the top of the weight scale sensor 7 buried at a position close to the light receiving part 6, the weight scale calculator 8 determines that the first axle of the dump truck 2 is C ton and the second axle is D ton. The weight of the ton is detected, and it is totaled and calculated as C+D=E.
Calculate as ton.

Furthermore, the difference between the empty vehicle weight B tons provided in advance is detected, and E
- A display corresponding to the loaded weight of B=F ton is made.

At the same time, an information signal corresponding to this net loaded weight is sent to the sub-control section 9 as a final output.

The sub-control unit 9 instructs the printing machine to print based on the time from a clock device prepared in advance and various information such as the vehicle number, type, weight, etc., and thereby the information is printed on the printing tape 10. appears.

At the same time, a test completion signal is sent to the display board 11.

As a result, the indicator light on the display board 11 lights up, indicating OK, the vehicle number, the loaded weight, etc., and notifying the driver of the dump truck 2.

In parallel, information similar to the above information is sent to the transmission line 1.
2 to the electronic computer 13 in the control room, where various information is aggregated and statistical work is performed.

In this way, for example, how many times did the vehicle with vehicle number 25 transport rough stones A, etc. during the operating hours of one day, how many tons did it transport in total, or how many tons of what did the vehicle transport in total? etc. are obvious.

Although the present invention has been explained above using an example of applying the present invention to construction work, the present invention is not limited to this, and can be applied to works in which objects are transported in self-propelled or non-self-propelled containers. Needless to say, this method can be easily implemented in the manufacturing process.

As is clear from the above description, according to the present invention, the passing time, vehicle number, type of vehicle, type of loaded object, loaded weight, etc. are stored and stored without stopping the transportation operation. information can be typed out,
In addition, it is possible to easily perform tasks such as compiling statistics on various types of information, and it also has the advantage of being able to record more efficiently and accurately than conventional methods, making it possible to manage various transportation operations accurately and quickly. Moreover, it saves labor and automatically performs centralized management such as aggregation work, so the practical effects are extremely high.

Furthermore, the present invention is extremely effective in that it eliminates the need to rely on manual operations as in the past, and thus can solve all the inconveniences caused by this.
