Problems solved by technology

In particular, since a relatively large structure such as an engine is arranged in a work vehicle, radio waves are shielded by such a structure, and the above-mentioned receiving range tends to be narrowed.
Therefore, there are cases where one sensor is not enough to properly obtain information from multiple IC chips

Embodiment Construction

[0045] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0046] [Explanation of the whole hydraulic excavator]

[0047] figure 1 It is a perspective view showing a hydraulic excavator 1 as an example of the work vehicle of the present invention.

[0048] In this embodiment, if figure 1 As shown, a hydraulic excavator 1 has a vehicle body 2 and a working machine 3 . The vehicle body 2 has a traveling device 4 and a revolving upper body 5 .

[0049] In addition, in the revolving upper body 5 , the side where the working machine 3 and the cab 5B are arranged is the front, and the side where the machine room 5A is arranged is the rear. When facing forward, the left side is the left side of the upper rotating body 5, and the right side is the right side of the upper rotating body 5 when facing forward. In addition, the hydraulic excavator 1 and the vehicle body 2 are based on the upper revolving body 5 , the travel device 4 side is...

Abstract

This identification information acquisition system provided in a working vehicle is equipped with a plurality of identifying devices (30A, 30B, 30C, 30D) and a plurality of communication devices (15) that communicate with the identifying devices (30A, 30B, 30C, 30D), the communication devices (15) include a first communication device (15A), and a second communication device (15B) movement of which is controlled by means of the first communication device (15A), and the first communication device (15A) is disposed at a working vehicle area having a temperature lower than that of a working vehicle area where the second communication device (15B) is disposed.

Description

technical field [0001] The present invention relates to an identification information acquisition system and a work vehicle provided with the identification information acquisition system. Background technique [0002] Conventionally, working vehicles such as construction machines (for example, hydraulic excavators and wheel loaders) and transport vehicles (for example, dump trucks) are known. The following technology is known: an IC chip as an identification element is mounted on replacement elements such as a filter mounted on such a work vehicle, and the information stored in the IC chip is acquired by a sensor to identify genuine products and counterfeit products (refer to Patent Document 1 ). [0003] In the replacement part identification device described in this patent document 1, an IC chip as an identification part is embedded in a genuine replacement part guaranteed by the manufacturer of the construction machine, and a reader (sensor) is arranged so as to be able...
