Abstract

PURPOSE:To easily confirm historical experiences and so on by mounting a non-contact type ID tug on a construction machine, and by storing the data on the point of failure, the content of repairing, and on auxiliary devices installed, and so on in a memory of the ID tug with a writer, and by reading the data with a reader. CONSTITUTION:An ID tug A is mounted on an operating chamber 2 and so on of a construction machine 1. The ID tug A is provided with a non-volatile memory 3, an encoder 4, and with a decoder 5, and also with an antenna (coil) 7 for power, and antennas 9, 10 for reading and writing, connected to a modulation/demodulation circuit 8, and the data can be written and read in a non-contact mode by a reader/writer B. The data of drafting, and the serial number of the construction machine are stored in the memory 3 of the ID tug a by the reader/writer B, and the point of failure or of breakage, the content of repairing when the failure or the breakage occurs, are constantly stored. The stored data is read when required, and is displayed on a display 13 or by a printer C, so as to know historical experiences and so on.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a management system for construction machinery.

[Conventional technology]

Construction machines often operate under harsh conditions and are therefore prone to breakdowns or damage, and are often equipped with various auxiliary equipment as options depending on the type of work being performed.

On the other hand, since construction machinery is expensive, some companies do not own their own construction machinery, but rather rent construction machinery for the job from a rental company.

[Problem to be solved by the invention]

When renting from a rental company as mentioned above,
Since it is not easy to know the past history of the construction machine, maintenance, etc. suitable for the construction machine cannot be performed, making management very troublesome.

Therefore, an object of the present invention is to provide a management system for construction machinery that can solve the above-mentioned problems.

[Means and effects for solving the problem] A non-contact type ID tag is attached to the construction machine, and data such as the location of failure, repair details, attached auxiliary equipment, etc. is recorded in the memory of this ID tag using a reader/writer. , the recorded data can be read out and displayed, making it easy to learn about the past history of the construction machine.

〔Example〕

As shown in FIG. 1, an ID tag A is attached to the operator's cab 2 or the like of the construction machine 1.

The ID tag A includes a nonvolatile memory (E2 memory) 3, an encoder 4, a decoder 5, and a power supply circuit 6.
The reader/writer B includes a power antenna (coil) 7 connected to a power antenna (coil) 7, a read antenna (coil) 9 connected to a modulation/demodulation circuit 8, and a write antenna (coil) 10.
It is a non-contact type that can be written and read without contact.

The reader/writer B includes a memory 11, a CPU 12, a display 13, a serial-parallel conversion circuit 14, an encoder 15, a decoder 16, a power supply circuit 17, and a power supply circuit 1.
8. 1 modulation/demodulation circuit, power antenna (coil)
20, a read antenna (coil) 21, a write antenna (coil) 22, and a power antenna 20 and an I
ID tag 2 by electromagnetic coupling of power antenna 7 of D tag 2
In addition to supplying power to the lead antenna 21.9
Data can be written and read between the reader/writer B and the ID tag A through mutual electromagnetic coupling and mutual electromagnetic coupling between the write antennas 22.10.

Further, the reader/writer B is equipped with a data communication port, and can print out necessary data by connecting it to a printer or personal computer C.

Then, the manufacturing date and model number of the construction machine are recorded in the memory 3 of the ID tag A by the reader/writer B at the manufacturing factory.

If this construction machine breaks down or is damaged,
A service person or repair person records the failure location, damage location, and repair details in the memory 3 of the ID tag A using the reader/writer B, and when an auxiliary device is installed as an option, the auxiliary device is stored in the memory 3 of the ID tag A. Record each time with reader/writer B.

Since the memory 3 is a non-volatile memory, the data recorded in the memory 3 will not be erased even if the power is turned off.

The data recorded in this way can be read out by the reader/writer B and displayed on the display 13 when necessary, and can also be printed out by the printer C. This makes it possible to easily know the past history of the construction machine when necessary, and to reduce maintenance costs. etc. will be easier to manage.

〔Effect of the invention〕

With reader/writer B, necessary data can be recorded, read, and
Since it can be displayed, the past history of the construction machine can be easily known, and maintenance suitable for the construction machine can be easily carried out, making management easier.

[Brief explanation of drawings]

FIG. 1 is a configuration explanatory diagram showing an embodiment of the present invention. A is an ID tag, B is a reader/writer, 3 is a memory, 13
is an indicator.

Claims (1)

[Claims] Contactless ID tag A with non-volatile memory 3
is attached to the construction machine, and reader/writer B records the manufacturing date and machine number in the memory 3 of this ID tag A, and the reader/writer B also records data such as failure/damage location, repair details, and auxiliary equipment installed. A management system for construction machinery, characterized in that data is recorded in the memory 3, and the data recorded in the memory 3 can be read and displayed by the reader/writer B.
