On the other hand, according to an embodiment of the present invention, the fixed rack 100 may be provided with a monitor 101 (for example, a touch screen monitor) that can control the movement for each moving rack. In addition, each of the movable racks 110 may be provided with an operation unit 111 that can move or stop the position of the rack or release the error mode. Detailed description thereof will be described later with reference to FIGS. 6 and 7.

Therefore, according to the embodiment of the present invention, the fixed rack 100 or the mobile rack 110 can exchange information through real time communication with all the other racks except themselves, and control other racks in real time.

2 is a view showing CAN communication between a fixed rack and a plurality of mobile racks to which the present invention is applied. Referring to FIG. 2, in the fixed rack 100, the mobile rack 110 requests and receives internal variable information of the corresponding mobile rack 110 through the CAN communication bus 120. Meanwhile, although FIG. 2 illustrates that the fixed rack 100 requests and receives internal variables from the plurality of mobile racks 110, it is also possible to communicate with one mobile rack 110.

Accordingly, if the fixed rack 100 communicates with the plurality of mobile racks 110 to request and receive internal variables from each mobile rack 110, the fixed rack 100 transmits the packets to each mobile rack. Preferably, the unique information for identifying 110 is further included.

As such, by performing N: N communication between the fixed rack 100 and the plurality of mobile racks 110 by the CAN communication protocol, information generated in each rack is simultaneously transmitted in real time to the remaining entire racks. Accordingly, it is also possible to simultaneously control the rest of the other racks in the fixed rack 100 or one mobile rack 110, it is possible to be processed in real time at the same time the entire rack is organically interlocked.

Hereinafter, detailed configurations of the moving rack and the fixed rack according to the embodiment of the present invention will be described in detail with reference to FIGS. 3 and 4.

3 is a block diagram showing a detailed configuration of a moving rack according to an embodiment of the present invention. Referring to FIG. 3, the mobile rack 110 according to the embodiment of the present invention includes a touch panel 310, an MCU 311, a digital input unit 312, a motor driver 313, a CAN driver 314, and a digital output.

As illustrated, each mobile rack 110 performs CAN communication with the fixed rack 100 or other mobile racks 110 through the CAN driver 314. Data transmitted to the other racks through the CAN driver 314 may be state information of the corresponding mobile rack 110, or may be a control signal for controlling other racks.

That is, when a control signal for another mobile rack 110 is transmitted to the other mobile racks 110 through the CAN driver 314, the control signal through the CAN driver 314 in the corresponding mobile rack 110. The motor 330 is driven by generating a current capable of driving the motor by driving the motor driver 313 under the control of the MCU 311. As the motor 330 is driven, the moving rack 110 moves in the set direction. In this case, the control signal provided from the motor driver 313 to the motor 330 is a pulse width modulation (PWM) signal, which enables fine adjustment of the speed of the motor 330.

On the other hand, the movable rack 110 is movable and can perform operations such as rack movement and stop, error cancellation, etc. using a touch panel (shown in FIGS. 1 and 6) mounted in the center of the rack. At this time, the movement of the rack is linked with the other rack through the CAN communication according to the embodiment of the present invention as described above, the operation control signal of the fixed rack 100 is also transmitted through the CAN communication.

A plurality of moving racks may be installed (for example, up to 31 units), the moving speed may be moved at, for example, 4 to 5 cm / s, and the speed may be adapted to be changed according to user requirements as described above. The rack mover also has an operator panel that allows the user to move directly to the rack position for the move operation. The user can move and stop the rack to the left or right by using the left / right moving buttons attached to the mobile rack 110, and reset the error state when the situation is released after an emergency. can.

If the moving rack (110) is moving, it stops moving and displays an error when detecting the upper left / lower sensors (321, 322), the upper right / lower sensors (323, 324) or the entry sensor (325). In addition, when the moving rack (110) is stopped, an error is displayed when the upper left / lower sensors (321, 322) and the upper right / lower sensors (323, 324) are detected. When the moving rack 110 is in a stopped state, an error is detected when the entry sensor 325 is detected, and the fluorescent lamp 340 is turned on by the fluorescent lamp controller 350. When the rack is started while the fluorescent lamp 340 is turned on, the fluorescent lamp 340 may be turned off.

4 is a block diagram showing a detailed configuration of a fixed rack according to an embodiment of the present invention. 4, the fixed rack 100 according to an embodiment of the present invention is a touch screen 410, LCD 420, backlight 421, LCD control unit 422, digital input unit 431, MCU (432) ), The touch controller 433, the CAN driver 434, the digital output unit 435, the detection sensors 441, 442, 443, and 444, the entrance sensor 445, the mobile rack power control unit 450, and the like. Can be configured.

As shown, the fixed rack 100 performs CAN communication through the mobile racks 110 and the CAN driver 434. Data transmitted to other racks (ie, mobile racks) through the CAN driver 434 may be state information of the corresponding fixed rack 100 or may be a control signal for controlling other mobile racks.

That is, when a control signal for the mobile rack 110 is transmitted to each of the mobile racks 110 through the CAN driver 434, the mobile rack 110 transmits the control signal through the CAN driver 314. The motor 330 is driven by generating a current capable of driving the motor by receiving and driving the motor driver 313 under the control of the MCU 311. As the motor 330 is driven, the moving rack 110 moves in the set direction as described above.

Meanwhile, the fixed rack 100 is a fixed rack which is not movable, and manages and controls the operation of the entire mobile rack 110 through CAN communication as described above. Installation position of the fixed rack 100 is preferably installed at the far right end or leftmost end of the rack row.

In addition, as shown in FIG. 7, the fixed rack 100 is equipped with a 5.7 ”touch screen mono LCD (MONO LCD) and provides an intuitive user operation based on a GUI (GRAPHIC USER INTERFACE). It is possible to make it easy for the user to use, and can provide clear information to the user in case of various emergencies. In addition, the operations of the upper left / lower sensors 441 and 442, the upper right / lower sensors 443 and 444, and the entry sensor 445 may perform the same operations as those of the above-described sensors of the mobile rack 110.

On the other hand, according to an embodiment of the present invention, each mobile rack 110 is supplied with power from the fixed rack 100, the driving power supplied to the drive motor 330 for moving each mobile rack 110 is described above. As described above, it is possible to finely adjust the speed of the drive motor by adjusting the intensity of the voltage as a PWM signal. Accordingly, the movement speed of each moving rack 110 can be adjusted.

5 is a flowchart illustrating an integrated control procedure of a mobile rack through data sharing according to an embodiment of the present invention. Referring to FIG. 5, when power is first supplied to a fixed rack (S501), power is supplied to each mobile rack through a solid static relay (SSR). The SSR is a semiconductor device without opening or closing a circuit by a contact. A relay that opens and closes a circuit by a photo coupler. In more detail, when the input switch is turned on, the light emitting diode in the photo coupler emits light, and the photo transistor is turned on upon receiving the light. Therefore, when the AC power supply voltage is substantially '0V' by the zero crossing circuit, the triac TRIAC of the output circuit is turned on and current flows in each of the mobile racks 110. Next, when the input switch is turned on, the output circuit is turned on when the load current is almost '0A' according to the operation characteristic of the TRIAC. By implementing the power supply between the fixed rack 100 and the mobile rack 110 through the SSR, the input and output are electrically insulated so that they are not affected by the outside. In addition, since no coil is used, noise is generated less. In addition, since the semiconductor device is used, there is an advantage that it operates at a small power.

As such, when power is supplied to each mobile rack from the fixed rack, and a moving command for the i-th moving rack is input (S503), the moving command is fixed to the fixed rack and all other moving racks according to an embodiment of the present invention. It transmits by CAN communication (S504).

Then, the positions of the racks are confirmed through communication between the racks, and the distance between the racks is confirmed by the proximity sensor (S505). Next, when the positions of the racks are identified and the distance between the racks is determined, a rack to be moved at the same time is determined (S506). At this time, the detection sensor between each rack is checked in real time (S507), and if there is no object between the racks as a result of the detection (S508), all the moving racks decided to move in the movement (S509) at the same time. At this time, the distance between the racks in real time through the proximity sensor installed between each rack (S510), if there is a rack sensed by at least one proximity sensor (that is, when the distance between the racks is less than the set distance). In operation S512, the mobile rack associated with the sensed rack is stopped.

According to the above procedure, when the movement of all the moving racks is completed (S513), the movement for the moving rack is terminated (S514).

As such, the fixed rack and the entire mobile rack communicate with each other by N: N in real time by the CAN protocol, thereby enabling real-time movement control of the entire mobile rack. Therefore, the movement of the moving rack can be efficiently controlled, and the movement speed becomes significantly faster according to the simultaneous movement.

Referring to FIG. 6, the front part of the moving rack 110 is provided with an operation unit 600, a left moving button 610 for moving the moving rack 110 to the left, and a right for moving to the right. It may include a move button 640. In addition, it may further include a stop button 630 for stopping the movement of the moving rack, and may further include an error reset button 620 for switching from the error state to the normal mode. At this time, even if the error reset button 620 is pressed in an error state, the object is not immediately switched to the normal mode, but when an object is not present between all racks as a result of the detection of the entire sensing sensor, the error state is reset to the normal mode. do.

7 is a view showing a monitor provided in the fixed rack according to an embodiment of the present invention. Referring to FIG. 7, unlike the movable rack 110, the fixed rack 100 may install a monitor 700 having a touch screen in the front portion. For example, as shown, the moving rack and the fixed rack can be visually displayed, and the position of each rack can be displayed. Therefore, it is possible to select, move and control the rack by a touch screen method.

Referring to FIG. 8, for example, the first mobile rack 110a next to the fixed rack 100 on the right side is moved to the left to enter the fixed rack 100 and the first mobile rack 110a. In this case, fast movement control is possible by simultaneously moving the entire mobile racks 110 by CAN communication according to an embodiment of the present invention.

That is, when a moving command for the first moving rack 110a is input through the monitor 101 or the operation unit 111 provided in the fixed rack 100 or the first moving rack 110a, the input moving command Is transmitted in real time to all remaining racks simultaneously.

At this time, each of the racks to check the distance between the racks by the proximity sensor, and check their position to share the information with the remaining racks in real time by the CAN protocol. Thereafter, even when the mobile rack 110 moves, its location information and proximity information are simultaneously shared with the remaining racks in real time.

When the entire sharing of information is completed by N: N communication as described above, not only the first mobile rack 110a but also the second mobile rack 110b and the third mobile rack adjacent to the first mobile rack 110a. 110c, ..., etc. move simultaneously.

In this case, as described above, the proximity distances are checked in real time by proximity sensors provided between the racks, and when the distances between the racks are close to the set distance or less, the movement of the corresponding rack is stopped.

In this way, the movement command for one mobile rack is shared by all the other racks, and all the mobile racks are moved at the same time, so that the fast moving rack can be moved.
