Description

The present invention relates to a detection device that is installed on a movable part, such as a boom, arm, or bucket, of a work machine.

One example of this type of detection device is known from the past, for example, the device described in Patent Document 1 below. The detection device described in Patent Document 1 is primarily composed of a sensor unit (inertial sensor) consisting of an angular velocity sensor and an acceleration sensor, and a rectangular board on which this sensor unit is mounted. The board is housed in a container (case member) with its four corners supported by cylindrical cushioning materials.

JP 2011-85441 A

However, in the case of the detection device described in Patent Document 1 mentioned above, the four corners of the board are supported by cushioning material, and the center of the board is not supported by cushioning material. As a result, it is possible that the center of the board may bend or resonate due to impacts, vibrations, etc. when the work machine is performing excavation work. The vibrations caused by such bending or resonance may then be transmitted to the sensor unit mounted on the board, potentially reducing the detection accuracy of the sensor unit.

The present invention was made in consideration of the above situation, and aims to provide a detection device that does not risk a decrease in the detection accuracy of the sensor unit.

The present invention is also characterized in that it is configured to include a power supply means for supplying power to the board and a cover member for covering the opening of the space, and the power supply means is positioned in the second space which is an area surrounded by the partition member, the case member and the cover member .

The present invention is also characterized in that the power supply means comprises a battery that serves as a power source for supplying the power, and a battery case that houses the battery.

The present invention is also characterized in that the substrate and the power supply means are arranged so as to overlap in the space.

The present invention is also characterized in that the partition member is provided in the space so as to be interposed between the substrate and the power supply means, and the substrate and the power supply means are held in place by the partition member.

Below, we will explain one embodiment in which the detection device of the present invention is applied to a work assistance system using Figures 1 to 9.

Figure 1 shows a work support system 1 according to an embodiment of the present invention, and Figure 2 is a block diagram of the work support system 1.

The work assistance system 1 uses machine guidance functions to assist the operator of a hydraulic excavator 2, a construction machine (mobile body). The hydraulic excavator 2 has a main body 3 that moves autonomously on caterpillar tracks, and movable parts such as a boom 4, arm 5, and bucket 6, which are sequentially mounted on the main body 3. The work assistance system 1 is not limited to hydraulic excavators 2, and can be widely applied to a variety of work machines used in civil engineering, construction, and agricultural work, such as construction machines used for ground improvement work. In the following description, the boom 4, arm 5, and bucket 6 may be referred to as movable parts.

As shown in FIG. 2, the work assistance system 1 is mainly composed of detection devices 11a, 11b, and 11c, a main unit 12, a mobile information terminal device 13, and a notification unit 14. Here, detection devices 11a, 11b, and 11c are provided on the boom 4, arm 5, and bucket 6, respectively, of the hydraulic excavator 2, and acquire information relating to the movement of the movable parts (e.g., attitude information of the movable parts) using a sensor unit described below, and send (output) the information relating to the movement of the movable parts to the main unit 12 via data communication using a wireless communication unit described below. Here, attitude information is information that can detect the attitude of each movable part, and in this embodiment, three-dimensional acceleration information and angular velocity information are applied.

Next, detection devices 11a, 11b, and 11c will be described. In this embodiment, detection devices 11a, 11b, and 11c have the same configuration, so the following description will focus on the configuration of detection device 11a, and descriptions of detection devices 11b and 11c will be omitted.

The detection device 11a is mounted on the boom 4 and, as shown in Figures 3 and 4, comprises a circuit board 20, a power supply means 30, a holding member 40, a case member 50, a cover member 60, a magnetic member 70, an attachment member 80, an airtight member 90, and a filling member 100.

The substrate 20 is a wiring board with a predetermined wiring pattern applied, and is disposed in the space H inside the case member 50. In this case, the sensor unit 21, control unit 22, and circuit components such as resistors and capacitors (not shown) are mounted (disposed) on one surface P1 of the substrate 20 facing the bottom side of the case member 50 (described below), and the wireless communication unit 23 connected to the control unit 22 is mounted on the other surface P2 of the substrate 20 opposite the one surface P1.

The sensor unit 21 can be, for example, a six-axis IMU (Inertial Measurement Unit) sensor that combines a three-dimensional acceleration sensor and an angular velocity sensor, and detects three-dimensional acceleration and angular velocity. The sensor unit 21 is not limited to the IMU sensor described above; a wide variety of configurations that can detect the attitude of the moving part can be used, such as an acceleration sensor, angular velocity sensor, or geomagnetic sensor. The measurement results from the sensor unit 21 are then processed by the control unit 22, which has a built-in arithmetic processing circuit, making it possible to obtain attitude information for the corresponding moving part.

The wireless communication unit 23 can be, for example, an antenna circuit pattern formed on the other surface P2 of the substrate 20, and can transmit the attitude information of the movable part processed by the control unit 22 to the main device 12 via wireless data communication. Note that the wireless communication unit 23 can also be a communication unit with an antenna instead of the above-mentioned antenna circuit pattern.

The power supply means 30 consists of a battery 31, which serves as a power source for supplying power to the circuit board 20, and a battery case 32 that houses the battery 31. The battery 31 consists of three dry cell batteries 31a to 31c arranged in parallel. The circuit board 20 operates on the power supplied from the battery 31, and the attitude information of the movable part processed by the control unit 22 is sent to the main device 12 via the wireless communication unit 23.

The battery case 32 is formed, for example, from a resin material and includes a base 32a that is parallel to the circuit board 20, a peripheral wall 32b that stands upright from the periphery of the base 32a, and partition walls 32c that separate the dry batteries 31a and 31b, and the dry batteries 31b and 31c. Focusing on the positional relationship between the circuit board 20 and the power supply means 30, the circuit board 20 and the power supply means 30 are arranged so that they overlap in space H inside the case member 50.

The holding member 40 is a generally flat resin case (inner case) that holds the board 20 and power supply means 30, and is provided in the space H inside the case member 50 so as to be interposed between the board 20 and the power supply means 30. The holding member 40 has a flat portion 41 that is provided parallel to the board 20, four protrusions 42 that protrude toward the board 20, and three positioning portions 43 (see Figure 5) for positioning and fixing the outer periphery 24 of the board 20.

The flat plate portion 41 of the holding member 40 is provided with a hole 41a for injecting the filling member 100 into a first space portion (described below), which is part of the space portion H (see Figure 5). The hole 41a is formed in approximately the center of the flat plate portion 41.

Furthermore, the flat plate portion 41 is joined to the battery case 32 with double-sided tape 44. This allows the flat plate portion 41 (holding member 40) to hold the battery case 32 (power supply means 30). Furthermore, since the battery case 32 (power supply means 30) is located directly above the flat plate portion 41 (on the cover member 60 side), if the battery 31 stops functioning (runs out of power), the battery 31 stored in the battery case 32 can be easily replaced by removing the cover member 60 from the case member 50. The area located directly above the flat plate portion 41 is configured as a second space portion, which is part of space portion H and will be described later.

Although detailed illustrations are omitted here, the protrusion 42 is provided with a threaded portion into which the screw S screws, and the substrate 20 is provided with a screw hole through which the screw S passes; the substrate 20 is fixed to the holding member 40 by fastening the screw S using the screw hole and the threaded portion. In other words, this means that the substrate 20 is held by the protrusion 42 (holding member 40).

The positioning portions 43 are, for example, positioning ribs for positioning and fixing the outer periphery 24 at three locations on the substrate 20. For example, in FIG. 5, two are provided along the longitudinal direction of the substrate 20, and one is provided along a direction approximately perpendicular to the longitudinal direction. The positioning portions 43 are provided to prevent the substrate 20 from shifting position when the substrate 20 and holding member 40 are fastened together using the screws S described above. In this example, the battery case 32 is joined to the flat plate portion 41, and the substrate 20 is fastened to the protruding portion 42 with the screws S, thereby holding the substrate 20 and power supply means 30 on the front and back of the holding member 40.

In addition, the holding member 40 here not only holds the substrate 20 and power supply means 30, but also functions as a partition member that separates (divides) the space H into two spatial regions, the first space and the second space. This means that the holding member 40 corresponds to the partition member described in the claims below.

The case member 50 is formed, for example, from a resin material, and houses the circuit board 20, power supply means 30, holding member 40, and a portion of the main body of the cover member 60 (described below) in its internal space H. The case member 50 has a bottom 51 serving as a first wall portion facing the circuit board 20, a roughly frame-shaped side portion 52 serving as a second wall portion surrounding the circuit board 20, power supply means 30, and holding member 40, and an opening 53 provided to correspond to the bottom 51.

The side portion 52 has a thick side portion 52a that is roughly frame-shaped, with the portion located on the open portion 53 side being thicker than the other portions. The thick side portion 52a (side portion 52) has a recessed portion 52b consisting of a frame-shaped groove provided in a position corresponding to the mounting portion of the cover member 60, which will be described later. Furthermore, support portions 52c are raised on the inside of the side portion 52 to support the rear side peripheral portion of the flat plate portion 41 facing the bottom portion 51. Four support portions 52c are provided here to support the four corners of the rear side peripheral portion, and are fixed to the flat plate portion 41 using appropriate fixing means such as screws.

In addition, in this example, the above-mentioned holding member 40 is provided in an approximately central region of space H, which is an area surrounded by the bottom 51 and side 52, so as to be approximately parallel to the bottom 51, thereby dividing space H into a first space H1 and a second space H2. The first space H1 is configured as an area surrounded by the holding member 40, bottom 51, and side 52 (i.e., the holding member 40 and case member 50). On the other hand, the second space H2 is configured as an area surrounded by the holding member 40, side 52, and cover member 60 (i.e., the holding member 40, case member 50, and cover member 60), and the power supply means 30 is positioned in this second space H2.

In this case, as shown in Figure 4, the substrate 20 on which the sensor unit 21 is mounted is positioned in the first space H1, which is the area surrounded by the holding member 40, the bottom 51, and the side 52. Furthermore, the hole 41a provided in the flat plate 41 of the holding member 40 is used to fill (inject) the filler 100 into the first space H1. Although not shown in detail, when injecting the filler 100 into the first space H1, a case member 50 is prepared in which only the holding member 40, which securely holds the substrate 20, is installed in the space H, and the power supply means 30 and cover member 60 are not installed in the space H. Then, the filler 100 is injected into the first space H1 through the hole 41a provided in the flat plate 41 so as to cover the substrate 20.

Note that 54 denotes six roughly semicircular first bulges that bulge outward from the thick side portion 52a (see Figure 6). These first bulges 54 have holes 54a for passing bolts T, shown by dotted lines in Figure 7, and are provided at the four corners, the center of the upper end, and the center of the lower end of the case member 50, which has space H in Figure 6.

The cover member 60 is formed, for example, from a resin material and is disposed on the thick side portion 52a (side portion 52) so as to close (cover) the open portion 53 of the space H. As shown in Figures 3 to 7, the cover member 60 comprises a main body portion 61 that constitutes its main portion, a mounting portion 62 that is formed around the main body portion 61 and is placed on the thick side portion 52a (side portion 52), a pair of protruding portions 63 that protrude left and right from the mounting portion 62 so as not to overlap with the case member 50, and six approximately semicircular ring-shaped second protruding portions 64 that protrude outward from the mounting portion 62 to correspond to the first protruding portions 54.

The main body 61 has a flat surface 61a facing the battery 31 and an exposed surface 61b located on the opposite side of the flat surface 61a. The flat surface 61a is arranged to abut against the battery 31, and the exposed surface 61b has two accommodation sections 61c with a generally concave cross section for accommodating the magnetic member 70. Threaded engagement section 61d is formed from accommodation section 61c toward the battery 31, and is used when screwing the cover member 60 and magnetic member 70 together.

In this embodiment, the flat surface 61a and the battery 31 abut against each other, but it is also possible to provide a gap between the flat surface 61a and the battery 31, and fill this gap with a cushioning material such as a sponge.

The mounting portion 62 has a generally frame-shaped protrusion 62a that fits into the recess 52b. The protrusion 63 has a positioning hole 63a that positions a positioning pin (described later) of the mounting member 80 (see Figure 8). The second bulge 64 has a hole 64a that corresponds to the hole 54a, as shown in Figure 7, and the cover member 60 is fastened to the case member 50 by fastening the bolt T to the holes 64a, 54a.

The magnetic member 70 is composed of a magnet 71 and a yoke 72 (which houses the magnet 71), both of which are made of a magnetic material. The magnet 71 is formed, for example, in a generally annular shape, and as shown in Figures 4 and 9, includes a first exposed portion 71a located on the mounting member 80 side, a corresponding portion 71b that is provided to correspond (face) to the first exposed portion 71a, and a side portion 71c that connects the first exposed portion 71a and the corresponding portion 71b. The first exposed portion 71a is configured as an annular exposed surface, the corresponding portion 71b is configured as an annular surface, and the side portion 71c is configured as a curved side surface. Furthermore, a generally inverted V-shaped hole 71d is formed in the center of the magnet 71, through which a fixing screw (described below) passes. The magnet 71 may have a shape other than an annular shape.

On the other hand, the yoke 72, made of an iron-based material, has a base 72a located on the corresponding portion 71b side and an enclosing portion 72b surrounding the side portion 71c, with a hole 72c formed in the center of the base 72a that communicates with the hole 71d. In this case, the first exposed portion 71a, which is configured as an annular exposed surface, is located approximately on the same plane as the exposed surface 61b of the main body 61, and the first exposed portion 71a and exposed surface 61b are one step lower than the second exposed portion 72d of the yoke 72, which is located on the tip side (mounting member 80 side) of the enclosing portion 72b. The second exposed portion 72d is configured as an annular exposed surface.

The magnetic member 70 configured in this manner is fixed to the cover member 60 with adhesive S1 and a fixing screw S2. That is, in this case, the base 72a (magnetic member 70) and the main body 61 (cover member 60) are joined together by adhesive S1 applied between the surface X1 of the base 72a and the opposing surface X2 of the housing portion 61c, and the magnetic member 70 and the main body 61 (cover member 60) are fixed together by fixing screws S2 that pass through holes 71d and 72c in sequence and screw into the threaded engagement portion 61d.

The mounting member 80 is a thin mounting plate made of a magnetic material that can be coupled (fixed) to the second exposed portion 72d of the yoke 72 by magnetic force. In other words, the mounting member 80 here is coupled to the magnetic member 70 by the second exposed portion 72d, and gaps G are formed between the mounting member 80 and the first exposed portion 71a, and between the mounting member 80 and the exposed surface 61b.

The mounting member 80, which is provided between the movable part (boom 4) and the cover member 60, has a pair of positioning pins 81 formed at the center of the left and right ends of the mounting member 80 in Figure 6, protruding toward the case member 50 (see Figures 4, 6, and 8). In this case, these pair of positioning pins 81 are positioned and fixed in a pair of positioning holes 63a in the protruding part 63, respectively, and are located on an imaginary line L in Figure 6 that divides the mounting member 80 (cover member 60) into two equal parts, above and below. In addition to the positioning pins 81 (positioning holes 63a), the magnetic member 70 (accommodating section 61c) is also located on this imaginary line L.

As shown in Figure 7, the airtight member 90 can be a substantially frame-shaped (approximately rectangular cross-section) gasket placed in the space 91 formed between the protrusion 62a and the recess 52b. In this case, the airtight member 90 is embedded in the recess 52b while compressed by the protrusion 62a. By providing the airtight member 90 in this manner, the airtight state of the space H surrounded by the case member 50 and the cover member 60 is maintained satisfactorily, and foreign matter such as moisture and dust can be prevented from entering the space H.

The filling member 100 is made of a thermoplastic resin such as epoxy resin or urethane resin, and is filled into the first space H1. The filling member 100 airtightly fixes the board 20, on which the sensor unit 21 and the circuit components are mounted, so that the board 20 remains immobile. Furthermore, by filling the first space H1 with the filling member 100, even if foreign matter such as water or dust enters the inside of the case member 50 due to deterioration of the airtight member 90 over time, for example, the filling member 100 ensures insulation between the board 20 and the foreign matter, thereby preventing malfunction of the board 20.

The above components make up the detection device 11a. The flat surface 82 of the mounting member 80, located on the opposite side from the positioning pin 81, is joined to the outer surface 4a of the boom 4 facing the flat surface 82 using double-sided tape 110, thereby securing the detection device 11a to the boom 4 (see Figure 4).

The main unit 12 is provided on the main body 3 of the hydraulic excavator 2, and acquires attitude information from the detection devices 11a, 11b, and 11c and transmits it via wireless data communication. It also receives support information via wireless data communication and outputs it to the notification unit 14. For this reason, as shown in FIG. 2, the main unit 12 includes a detection unit 12a, a microcomputer 12b, and a communication unit 12c that transmits and receives various data between the detection devices 11a, 11b, and 11c and the portable information terminal device 13 via wireless data communication.

Detection unit 12a has the same configuration as detection devices 11a, 11b, and 11c, and acquires posture information about main body 3. Microcomputer 12b controls the operation of each component by executing a control program related to main body device 12 using a built-in arithmetic processing circuit. As a result, microcomputer 12b, in response to instructions from mobile information terminal device 13, processes the measurement results output from detection unit 12a to acquire posture information about main body 3, and also acquires posture information from detection devices 11a, 11b, and 11c.

The microcomputer 12b also transmits this posture information to the portable information terminal device 13 via wireless data communication. The microcomputer 12b also receives support information transmitted from the portable information terminal device 13 and outputs this support information to the notification unit 14. Note that support information here refers to support information that supports the operator's operation. Furthermore, if sufficient for practical use, the detection unit 12a may be omitted as necessary.

The mobile information terminal device 13 is a smartphone or tablet terminal that executes application software related to this work assistance system 1 to generate assistance information to assist the operator in their operations based on posture information obtained by the detectors 11a, 11b, and 11c via the main unit 12 and posture information acquired by the detector 12a. In this embodiment, this assistance information is assigned the difference from the construction target of the hydraulic excavator 2 (the amount of movement to the construction target), thereby enabling easy and reliable construction using the assistance information.

The mobile information terminal device 13 includes a microcomputer 13a, a communication unit 13b, and a display unit 13c. The mobile information terminal device 13 acquires posture information from the main device 12 through wireless data communication via the communication unit 13b, and outputs support information to the main device 12 to assist the operator in their operations. The mobile information terminal device 13 also acquires application software related to the work support system 1 from a server on the network.

The mobile information terminal device 13 executes application software acquired via the communication unit 13b on the microcomputer 13a and detects the attitude of the main body 3 from attitude information acquired in a reference attitude (for example, the attitude of the bucket 6 when placed on the ground at the start of construction). The mobile information terminal device 13 also calculates the change in attitude (amount of movement) of each moving part based on changes in each piece of attitude information from this reference attitude, and calculates the current position of the bucket 6.

The microcomputer 13a accepts the setting of the construction target in advance, sequentially calculates the current position of the bucket 6 based on the posture information sequentially input from the main unit 12, and calculates the amount of movement to the construction target by calculating the deviation (difference value) from the construction target. The microcomputer 13a also outputs this calculated amount of movement to the construction target as support information from the communication unit 13b via the main unit 12 using the notification unit 14.

The microcomputer 13a also executes a process to sequentially display the calculation results of the movement amount up to the construction target on the display unit 13c, which is configured as a display medium such as a liquid crystal display panel. In this case, the notification unit 14 may also display the same content as that displayed on the display unit 13c.

The notification unit 14 notifies the operator in the driver's seat of the hydraulic excavator 2 of support information that is input from the main unit 12 to assist the operator in his or her operations. In this embodiment, the notification unit 14 displays, for example, the amount of movement to the construction target using a segment display using light-emitting diodes.

The notification unit 14 may be configured as an image display panel or the like. When using an image display panel or the like to provide notification, various methods can be applied, such as displaying a numerical value or a meter. Furthermore, instead of a segment display or a display on an image display panel, notification may be provided by voice or an alarm sound. The notification unit 14 may also be driven directly by the mobile information terminal device 13.

As described above, this embodiment comprises a case member 50 having a space H, a holding member 40 that divides the space H into a first space H1 and a second space H2, a sensor unit 21 that acquires information related to the movement of the boom 4 provided on the hydraulic excavator 2 and outputs the acquired information related to the movement, and a circuit board 20 on which this sensor unit 21 is disposed. The circuit board 20 is positioned in the first space H1, which is an area surrounded by the holding member 40 and the case member 50, and the first space H1 is filled with a filling member 100 so as to cover the circuit board 20.

As a result, the filling member 100 is filled into the first space H1 so as to cover the substrate 20, and the substrate 20 is placed in an airtight manner in the first space H1 so as to be immobile. This prevents the substrate 20 from bending, and vibrations caused by the bending due to impacts, vibrations, etc. are not transmitted to the sensor unit 21 mounted on the substrate 20 during excavation work with the hydraulic excavator 2, making it possible to provide a detection device that does not risk a decrease in the detection accuracy of the sensor unit 21.

In addition, in this embodiment, the power supply means 30 is positioned in the second space H2, so if the battery 31 stops functioning (runs out of power), the battery 31 stored in the battery case 32 can be easily replaced by removing the cover member 60 from the case member 50.

In addition, in this embodiment, the substrate 20 and the power supply means 30 are arranged so that they overlap in the space H, which prevents the side portion 52 of the case member 50 from becoming too large, making it possible to provide a compact detection device.

The present invention is not limited to the above-described embodiments and drawings. Changes (including the deletion of components) can be made to the embodiments and drawings as appropriate, provided that the gist of the present invention is not altered.

For example, in the embodiment described above, the sensor unit 21 was mounted on one surface P1 of the substrate 20. However, as a modified example of this embodiment, a covering member 25 such as a protective cap for covering the sensor unit 21 may be disposed (fixed) on one surface P1 of the substrate 20, as shown in Figures 10 and 11.

The covering member 25 includes, for example, a base portion 25a that is parallel to the substrate 20, and a peripheral wall 25b that is located between the periphery of the base portion 25a and the substrate 20. By providing the covering member 25 that covers the sensor portion 21 on the substrate 20 in this manner, the same effects as those of the previous embodiment can be achieved.

The covering member 25 may have any shape that covers the sensor unit 21. For example, although not shown in detail here, a covering member consisting of a base portion 25a, a peripheral wall 25b, and a flange portion extending around the peripheral wall 25b so as to abut against the substrate 20 can be used.

In addition, in the above-described embodiment, one hole 41a used to fill the first space H1 with the filling member 100 was provided in the flat plate portion 41. However, the number of holes 41a may be multiple.
