The present invention can be applied not only to management of work vehicles, but also to management of use of various work devices rented at a work site.

First Embodiment
FIG. 1 is a block diagram showing a configuration example of the operation detection communication module 3 (first communication device). The operation detection communication module 3 is provided, for example, on a work vehicle 10 used at a work site such as a construction site. The work vehicle 10 is, for example, a high-level work vehicle, a high-level truck, a dump truck, a crane truck, a special vehicle such as a forklift, and an ordinary vehicle such as a one-box vehicle. The operation detection communication module 3 is a communication device provided with various sensors.
In the use management system 1 of the present embodiment, the work detection communication module 3 is provided in the work vehicle 10, so that the use situation (use situation) of the work vehicle 10 can be grasped and managed.

  As shown in FIG. 1, the operation detection communication module 3 includes an operation sensor 30, an air pressure sensor 31, a tag reader 32, a collision sensor 33, a control unit 34, and a communication unit 35 (first communication unit). And a power supply unit 36. The operation sensor 30, the air pressure sensor 31, the tag reader 32, and the collision sensor 33 correspond to an acquisition unit.

  The operation sensor 30 is, for example, a clamp-type current sensor having a clamp 300. The operation sensor 30 clamps the positive (+) terminal of the power supply unit 110 of the work vehicle 10 by the clamp 300 to detect the value of the current flowing through the work vehicle 10. The operation sensor 30 outputs the detected current value to the control unit 34. The power supply unit 110 is, for example, a power supply battery of the work vehicle 10, and supplies power to a corresponding drive unit (not shown) of the work vehicle 10 when various operations are performed in the work vehicle 10.

  The pressure sensor 31 is a barometer that detects the pressure of the atmosphere. The atmospheric pressure sensor 31 is, for example, built in the operation detection communication module 3 and detects the pressure of the atmosphere at a place where the work vehicle 10 to which the operation detection communication module 3 is attached is disposed. The pressure sensor 31 outputs information indicating the detected pressure of the atmosphere to the control unit 34.

  The tag reader 32 reads usage information on the use of the work vehicle from the recording medium provided in the delivery item delivered when the work vehicle 10 is rented according to the normal procedure. Delivery items to be delivered when rented by a formal procedure include a trader plate, a driving key of a work vehicle, and the like. A tag is used as a recording medium.

  When impact sensor 33 receives an impact, it generates an output voltage corresponding to the degree of impact at that time. The collision sensor 33 is mounted on the body portion 11 of the work vehicle 10 such that the sensing direction thereof is the traveling direction of the work vehicle 10. The collision sensor 33 outputs, for example, a voltage value proportional to the detected shock. From the magnitude of the voltage value output from the collision sensor 33, the magnitude of the impact received at the location where the collision sensor 33 is provided can be determined.

  The control unit 34 is implemented, for example, by a processor such as a central processing unit (CPU) executing a program stored in a program memory. The control unit 34 determines various outputs from the operation sensor 30, the barometric pressure sensor 31, the tag reader 32, and the collision sensor 33, and performs various controls.

  The communication unit 35 mutually communicates with the operation detection communication module 3 of the other work vehicle 10 different from the work vehicle 10, the base floor relay module 4 and the management device 5 (second communication device) (FIG. 2) reference). The communication unit 35 transmits information to the management device 5 based on control of the control unit 34, for example. Further, the communication unit 35 relays the information transmitted from the other operation detection communication module 3 and the reference floor relay module 4 to the management device 5.

  The power supply unit 36 supplies power to each component of the operation detection communication module 3. In FIG. 1, the power supply unit 36 shows an example in the case of receiving supply of power from the power supply unit 110 of the work vehicle 10. However, the present invention is not limited to this. For example, the power supply unit 36 may be a storage battery built in the operation detection communication module 3 or a power supply cable for supplying power to the operation detection communication module 3 or the like. It may be.

  In the present embodiment, when such a work vehicle 10 is to be rented according to a formal procedure, a contractor plate, a driving key of the work vehicle, and the like are delivered to the rental user. A received item delivered when the work vehicle 10 is rented in these normal procedures is provided with a tag in which usage information on the use of the work vehicle is written.

Detection signals of the operation sensor 30, the barometric pressure sensor 31, the tag reader 32, and the collision sensor 33 are supplied to the control unit 34 of the operation detection communication module 3. The control unit 34 generates various types of information based on these detection signals. Then, the communication unit 35 of the operation detection communication module 3 transmits various information acquired from the operation sensor 30, the barometric pressure sensor 31, the tag reader 32, and the collision sensor 33 to the management device 5.

  That is, the operation sensor 30 acquires operation information indicating whether the work vehicle 10 is operating. Further, the barometric pressure sensor 31 acquires barometric pressure information at the place where the work vehicle 10 performs the work. Further, the tag reader 32 obtains usage information. Further, when there is a collision accident of the work vehicle 10, the collision sensor 33 acquires information on the degree of impact at that time. The communication unit 35 of the operation detection communication module 3 associates the operation information, the barometric pressure information, the use information, and the impact degree information when there is a collision with the identification information of the work vehicle 10, and manages the management device 5 every predetermined time. Send to

The reference floor relay module 4 acquires information (hereinafter, referred to as reference floor pressure information) indicating the pressure in the reference floor by the pressure sensor 40. The communication unit 42 of the reference floor relay module 4 transmits the acquired reference floor pressure information to the management device 5.

The control unit 51 of the management device 5 determines the operating state of each work vehicle 10 to which each operation detection communication module 3 is attached, based on the operation information received from the communication unit 35 of each operation detection communication module 3.

  In addition, the control unit 51 of the management device 5 calculates the air pressure of each floor corresponding to the height of each floor based on the height of each reference floor and the reference floor pressure information received from the communication unit 42 of the reference floor relay module 4 . Then, based on the barometric pressure information received from the communication unit 35 of the operation detection communication module 3, the control unit 51 of the management device 5 determines the work floor indicating where in the height direction the work vehicle 10 is disposed. . For example, by dividing the pressure difference of each of two reference floors by the difference of each height, the pressure of the floor located between the two reference floors can be derived. Based on the derived atmospheric pressure of each floor, it can be determined where the work floor of the work vehicle 10 to which the operation detection communication module 3 is attached is.

  In addition, the control unit 51 of the management device 5 determines the worker operating the respective work vehicles 10 based on the use information received from the communication unit 35 of the operation detection communication module 3. Further, the control unit 51 of the management device 5 determines the use status, such as whether or not unauthorized use has occurred, based on the use information received from the communication unit 35 of the operation detection communication module 3. Whether or not unauthorized use has been made can be determined by whether or not the use information has been read from the tag reader 32.

  Further, the control unit 51 of the management device 5 determines the occurrence of the collision based on the degree of impact information received from the communication unit 35 of the operation detection communication module 3. Whether or not there is a collision accident can be determined from the impact degree information sent from the operation detection communication module 3 to the management device 5.

  Further, the control unit 51 of the management device 5 generates a usage status management table by work floor indicating the status of the work vehicle 10 for each determined work floor. The use status management table by work floor is where each work vehicle 10 is located, and the operation state thereof is associated with the occurrence of an alert such as unauthorized use or a collision.
