Description

  The present invention relates to an identification information reading device that reads information of each identification mark in a large number of solar cell modules arranged in a matrix.

  2. Description of the Related Art Conventionally, a photovoltaic power generation system includes a solar cell array having a panel shape that is installed in a tilted state on the ground or a roof, and the solar cell array is orthogonal to the first direction extending horizontally and the first direction. In addition, a large number of solar cell modules are regularly arranged in a matrix in the second direction extending in an inclined manner. Each solar cell module needs to be managed by associating identification information such as its model name and manufacturing number with the installation position, and the operation of associating the identification information of each solar cell module with the installation position In general, after the solar cell array is installed, information of an identification mark such as a barcode provided on the panel surface of each solar cell module in the solar cell array is read.

  For example, in Patent Document 1, an identification information reader is used to efficiently read information of identification marks provided on the panel surfaces of all the solar cell modules in the solar cell array. The identification information reading device is provided with a rod-shaped mounting frame extending linearly in the second direction and both ends of the mounting frame, and is slidably fitted to the upper edge and the lower edge of the solar cell array, respectively. And a pair of sliders for guiding the movement of the mounting frame in the first direction. A plurality of information readers capable of reading information on the identification marks of the respective solar cell modules are attached to the attachment frame at predetermined intervals in the second direction, and an operator attaches the attachment frame to the first direction. As a result, the information reader reads the information of each identification mark as the reading section of each information reader passes the identification mark of each solar cell module.

JP-A-2006-91136

  By the way, in the case of the identification information reading device disclosed in Patent Document 1, it is necessary for the operator to manually move the mounting frame in the first direction, and there is a problem that the identification information reading operation is complicated.

  In order to cope with this, in an apparatus such as Patent Document 1, information on the identification mark of each solar cell module is obtained while moving the mounting frame in the first direction by automatically moving the apparatus in the first direction. It can be considered to read.

  However, when the device automatically travels, for example, when there is no solar cell module that the device travels next to the front of the traveling device, such as the end of the solar cell array, the traveling device currently travels. It is necessary to take measures not to fall from the end of the solar cell module inside.

  On the other hand, for example, it is conceivable to attach to the apparatus a detection unit that detects whether or not there is a solar cell module in which the apparatus travels next in front of the traveling apparatus.

  However, when there is a solar cell module that travels next in front of the traveling device, when the detection unit detects a gap between the solar cell module that is currently traveling and the solar cell module that travels next, It is necessary that the control unit of the apparatus does not erroneously determine that there is no solar cell module to travel next and stop the apparatus unnecessarily.

  The present invention has been made in view of such a point, and an object of the present invention is to prevent the apparatus from being dropped from the solar cell module and useless in an identification information reading apparatus capable of reading identification information by automatic traveling. An object of the present invention is to provide an identification information reader capable of preventing both stoppage of travel.

  In order to achieve the above object, the present invention is characterized in that it can be determined by using two detection means whether or not a solar cell module to travel next is in front of the apparatus.

  Specifically, on the panel surface in each of the solar cell modules of the module group in which a large number of solar cell modules are arranged in a regular matrix form in a first direction and a second direction orthogonal to the first direction. The following solution was taken for the identification information reader that reads the information of the provided identification mark.

  That is, in the first invention, it has a traveling means placed on the module group, and is attached to the apparatus main body, the apparatus main body movable along the first direction by the traveling operation by the traveling means, When the apparatus main body moves in the first direction, the reading section passes through the surface of the identification mark of each solar cell module, and is attached to the apparatus main body. The detection position for detecting the presence or absence of the solar cell module is a first detection means provided on the front side in the running direction from the center of gravity position of the device main body, and the detection is attached to the device main body and detects the presence or absence of the solar cell module. The position of the apparatus main body is set on the front side in the traveling direction so that the position is more than the size of the gap between the solar cell modules and the distance from the detection position of the first detection means. And a control means provided in the apparatus main body and connected to the travel means, the first detection means, and the second detection means, respectively. When both the second detection means cannot detect the solar cell module, the second detection means is configured to output a travel stop signal to the travel means.

  According to a second invention, in the first invention, the detection position of the first detection means is the first direction when the distance between the front end position of the device main body and the gravity center position in the first direction is D. The distance D1 between the center of gravity position of the apparatus main body and the detection position of the first detection means is set so that D1 ≧ D / 2.

  According to a third aspect, in the first or second aspect, the apparatus main body includes a main body case that accommodates the control means and the first detection means, and the second detection means includes the second detection means. It is attached to the front-end part of the said main body case so that a detection position may become the position of the diagonally downward of the front side of the said main body case.

  According to a fourth invention, in the third invention, the second detection means is an ultrasonic sensor.

  According to a fifth invention, in any one of the first to fourth inventions, the travel means is configured to be able to change the travel direction of the first direction, and the first detection means is configured to change the travel direction of the apparatus main body. A pair is provided so as to be located on one side and the other side in one direction, respectively, and a pair of the second detection means is provided so as to be located on one side and the other side in the first direction in the apparatus main body. It is characterized by being.

  In the first invention, for example, when there is no solar cell module that travels in front of the traveling device as in the end portion of the solar cell array, the traveling device exceeds the end of the solar cell module. When doing so, first, the solar cell module disappears at the detection position of the second detection means, and then the solar cell module disappears also at the detection position of the first detection means, so that both the first and second detection means are solar cell modules. Will not be detected. Therefore, since the control means stops the travel of the device, the device can be prevented from falling from the end of the solar cell module. On the other hand, when there is a solar cell module that travels next in front of the traveling device, when the traveling device tries to exceed the end of the solar cell module, first, the solar cell is at the detection position of the second detection means. After the module disappears, when there is no solar cell module at the detection position of the first detection means, the solar cell module is at the detection position of the second detection means, and at least one of the first and second detection means is The solar cell module is detected. Therefore, since the control means continues the running of the apparatus, the apparatus is not stopped unnecessarily.

  In the second invention, when the control means stops traveling of the apparatus, the distance D1 from the detection position of the first detection means to the center of gravity position of the apparatus main body is from the detection position of the first detection means to the front end position of the apparatus main body. Longer than the distance L. Therefore, the downward force applied to the front portion of the device body is reduced, and when the device stops near the end of the solar cell module, it is reliably prevented from dropping from the end of the solar cell module. be able to.

  In the third aspect of the invention, since the front end portion of the main body case is located behind the detection position of the second detection means, the dimension in the first direction at the front portion of the main body case can be shortened, and the device main body is Can be compact in one direction.

  In the fourth invention, since the sensor part can detect reflection of a wide range of sound waves, even under a severe detection condition that the detection position of the second detection unit is obliquely below the second detection unit. The presence or absence of the solar cell module can be reliably detected.

  In the fifth invention, since the traveling direction in the first direction can be changed without changing the mounting state of the apparatus, the complicated work of changing the posture of the apparatus in order to change the traveling direction in the first direction. This eliminates the need for the operator to reduce the load on the operator. Further, even if the traveling direction in the first direction is changed without changing the mounting state of the device, the detection positions of the first and second detection means are located on the front side in the traveling direction of the device. It is possible to prevent dropping from the solar cell module and useless stopping during traveling.

  Further, a battery 10b is accommodated in the main body case 3, and both the traveling crawlers 4 are driven by electric energy from the battery 10b.

  As shown in FIGS. 1 to 3, the main body case 3 includes the two drive motors 46, the bar code readers 6, the laser sensor 7, the ultrasonic sensor 9, the speaker 10a, and the battery 10b. The control part 8 (control means) connected to is accommodated.

  When the laser sensor 7A and the ultrasonic sensor 9A cannot detect the module 13 or the laser sensor 7B and the ultrasonic sensor 9B cannot detect the module 13 At this time, the driving motor 46 is configured to output a travel stop signal.

  Further, the control unit 8 outputs an operation signal to the speaker 10a so that a warning sound is emitted to the worker when the remaining amount of the battery 10b is equal to or less than a predetermined value. .

  Next, when there is no module 13 to travel next in front of the traveling identification information reader 1, the traveling operation when the traveling identification information reader 1 attempts to cross the end of the module 13 will be described in detail. Will be described in detail.

  First, as shown in FIG. 5, when the identification information reader 1 is traveling at one speed in the first direction X1 at the speed V, the end of the solar cell array 11 (the end of the module 13) is attempted to be exceeded. Then, the module 13 disappears at the detection position Q1 of the ultrasonic sensor 9A, and the ultrasonic sensor 9A cannot detect the module 13. However, since the module 13 is present at the detection position P1 of the laser sensor 7A and the laser sensor 7A detects the module 13, the control unit 8 detects the module 13 using the laser sensor 7A. No travel stop signal is output to the drive motor 46.

  Next, as shown in FIG. 6, when the identification information reading apparatus 1 further travels from the state of FIG. 5 to one side in the first direction X1 at a speed V, not only the detection position Q1 of the ultrasonic sensor 9A but also the laser The module 13 is not present at the detection position P1 of the sensor 7A, and neither the laser sensor 7A nor the ultrasonic sensor 9A detects the module 13. Then, the control unit 8 determines that the device main body 2 may fall from the end of the solar cell array 11, and outputs a travel stop signal to the drive motor 46 to run the identification information reading device 1. Stop. As described above, in the identification information reading device 1 according to the embodiment of the present invention, the control unit 8 stops the traveling of the identification information reading device 1 at the end portion of the solar cell array 11. Does not fall.

  In the case where the identification information reader 1 approaches the end of the solar cell array 11 in a state where the identification information reading device 1 is traveling at the speed V in the other side of the first direction X1, the laser sensor 7A and the ultrasonic sensor 9A described above. Similarly, the identification information reader 1 is prevented from falling from the end of the solar cell array 11 using the laser sensor 7B and the ultrasonic sensor 9B.

  Next, when there is a module 13 that travels next in front of the traveling identification information reader 1, the traveling operation when the traveling identification information reader 1 attempts to cross the end of the module 13 is specifically described. Will be described in detail.

  First, as shown in FIG. 7, when the identification information reading device 1 is traveling at a speed V in one side in the first direction X1, the traveling identification information reading device 1 will exceed the end of the module 13. Then, the module 13 disappears at the detection position Q1 of the ultrasonic sensor 9A, and the ultrasonic sensor 9A cannot detect the module 13. However, since the module 13 is present at the detection position P1 of the laser sensor 7A and the laser sensor 7A detects the module 13, the control unit 8 detects the module 13 using the laser sensor 7A. No travel stop signal is output to the drive motor 46.

  Next, as shown in FIG. 8, when the identification information reading device 1 further travels from the state of FIG. 7 to the one side in the first direction X1 at the speed V, the module 13 disappears at the detection position P1 of the laser sensor 7A. There is a module 13 at the detection position Q1 of the ultrasonic sensor 9A, and the ultrasonic sensor 9A detects the module 13, while the laser sensor 7A does not detect the module 13. That is, since at least one module 13 of the laser sensor 7A and the ultrasonic sensor 9A is being detected, the control unit 8 reads the identification information without outputting a travel stop signal to the drive motor 46. The travel of the device 1 is continued. As described above, the identification information reading device 1 according to the embodiment of the present invention tries to exceed the end of the traveling module 13 when the next traveling module 13 is in front of the identification information reading device 1. When this happens, the control unit 8 keeps the identification information reading device 1 running, so it does not stop uselessly.

  When the identification information reader 1 travels at the speed V on the other side in the first direction X1, when the module 13 that travels next is ahead of the identification information reader 1, the control unit 8 Like the laser sensor 7A and the ultrasonic sensor 9A, the laser sensor 7B and the ultrasonic sensor 9B are used to prevent the traveling of the identification information reader 1 from being uselessly stopped.

  Note that the case where the module 13 that travels next in front of the traveling identification information reading device 1 is not only the case where the identification information reading device 1 travels on one solar cell array 11, for example, 2 The case where the two solar cell arrays 11 are arranged side by side and the identification information reader 1 travels across the two solar cell arrays 11 is also included.

  In the embodiment of the present invention, if the distance between the front end position of the apparatus main body 2 and the center of gravity C in the first direction X1 is D, the center of gravity C of the apparatus main body 2 in the first direction X1 and the laser sensor 7A. Since the distance D1 to the detection position P1 is set so that D1 ≧ D / 2, the detection position P1 of the laser sensor 7A exceeds the end of the solar cell array 11, and the control unit 8 drives the drive motor. When stopping 46, the distance D1 from the detection position P1 of the laser sensor 7A to the center of gravity C of the apparatus body 2 becomes longer than the distance L from the detection position P1 of the laser sensor 7A to the front end position of the apparatus body 2, The downward force applied to the front portion of the apparatus main body 2 is reduced, and when the identification information reading apparatus 1 stops near the end of the module 13, the momentum drops from the end of the module 13. It can be surely prevented.

  Furthermore, since the ultrasonic sensor 9A is attached to the front end portion of the main body case 3 so that the detection position Q1 of the ultrasonic sensor 9A is an obliquely lower position on the front side in the forward direction in the main body case 3, the front end of the main body case 3 The portion is located behind the detection position Q1 of the ultrasonic sensor 9A. Therefore, the dimension of the first direction X1 in the front portion of the main body case 3 can be shortened, and the apparatus main body 2 can be made compact in the first direction X1.

  In addition, in the embodiment of the present invention, since the ultrasonic sensor 9A is used as the means for detecting by the module 13 at the detection position Q1, the sensor portion can detect reflection of a wide range of sound waves, and the detection position Q1. Even under the severe detection condition that is at a position obliquely below the ultrasonic sensor 9A, the presence or absence of the module 13 can be reliably detected.

  Further, since the traveling crawler 4 can change the traveling direction of the first direction X1, the traveling direction in the first direction X1 can be changed without changing the placement state of the identification information reading device 1, and the first direction X1 can be changed. In order to change the traveling direction in the direction X1, it is not necessary to perform a complicated operation such as changing the posture of the identification information reading device 1, and the load on the operator can be reduced.

  The laser sensors 7A and 7B are located on one side and the other side in the first direction X1 in the apparatus main body 2, respectively, and the ultrasonic sensors 9A and 9B are on one side in the first direction X1 in the apparatus main body 2. And the other side, even if the traveling direction in the first direction X1 is changed without changing the mounting state of the identification information reading device 1, the laser sensor is moved forward in the traveling direction of the identification information reading device 1. The detection positions P1 and Q1 of 7A and the ultrasonic sensor 9A (or the detection positions P2 and Q2 of the laser sensor 7B and the ultrasonic sensor 9B) are positioned, and the fall from the module 13 of the identification information reader 1 It is possible to prevent a useless stop during traveling.

  In the embodiment of the present invention, the information of each module 13 is displayed by a barcode 15 as an identification mark, and the information of the barcode 15 is read by a barcode reader 6 as information reading means. For example, the information of each module 13 may be displayed by an IC tag as an identification mark, and the information of the IC tag may be read by an IC tag reader as information reading means.

  In the embodiment of the present invention, the pair of traveling crawlers 4 is used as a means for traveling the apparatus main body 2. However, the present invention is not limited thereto, and for example, a pair of pneumatic tires is used as the means for traveling the apparatus main body 2. May be.

  Furthermore, in the embodiment of the present invention, the laser sensor 7 and the ultrasonic sensor 9 are used as means for detecting whether or not the apparatus main body 2 has the module 13. However, the present invention is not limited to this. It may be used.

  In addition, in the embodiment of the present invention, when the remaining amount of the battery 10b becomes a predetermined value or less, a warning sound is emitted from the speaker 10a to the worker. A visual warning may be provided by a light.

  The identification information reading device 1 of the present invention is used in the solar cell array 11 that is horizontal in the first direction X1 and inclined in the second direction X2, but is not limited thereto, and is used in the second direction X2. The solar cell array 11 that is horizontal and inclined in the first direction can also be used.
