Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 4 is a circuit diagram of an embodiment of a section controller of an electronic sign control apparatus of the present invention, FIG. 5 is a flowchart illustrating an operation process of the section controller of FIG. 4, and FIG. 6 is assigned to sections of the electronic sign control apparatus of FIG. It is a data map visually showing the change of address.

A data frame including channel information, section address information, section image information, and address setting information is generated from the main controller 300 of FIG. 1, and the generated data frame is transmitted to the corresponding channel according to the channel information. Each channel has a large number of sections connected from the top section to the bottom section to transmit data frames.

A section controller 600 is installed in each section, and the section controller 600 has an input interface unit 601 that receives a data frame from an adjacent section controller and an output interface for transmitting data to another adjacent section controller. Control unit 603, an LED drive unit 604 for driving the LED, an address setting module 610 for allocating addresses of each section, an operating system (OS), and a program for controlling the control object. Section 602.

The address setting module 610 may be composed of a series of programs implemented in the controller 602, and may be configured by firmware operating in association with the controller 602, and such modifications are subject to design considerations. .

As shown in FIG. 5, the controller 602 transmits a data frame including section address information, section image information, and address setting information to a channel.

The address setting information includes initialization information for resetting a predetermined address in the section controller 600 and set information for inputting a real address after a reset.

The controller 602 of the section controller 600 drives the address setting module 610 when address setting information is included in the data frame. The address setting module 610 determines whether the address setting information is initialization information or set information (S1) and (S2).

If the address setting information is initialization information, the address setting module 610 initializes the addresses of the section controllers 600 to 0 (S3).

The main controller 300 outputs address set information to the channel after the initialization is completed. At this time, the value 1 of the address set information generated from the main controller 300 is inputted first in the uppermost section to be connected first. The section controller of the uppermost section recognizes that it is the uppermost section by inputting the address set information 1 and stores it in the address storage unit.

The address setting module 610 of the uppermost section controller 600 generates a new address 2, which is increased by 1 to its own address 1, and transmits the new address 2 to the section controller of the lower section.

As such, the address set information consists of address set information of 1 that specifies the top section that specifies the section that is initially connected to the main controller and address set information that specifies the lower sections that are sequentially linked to the top sections.

If the input address set information is 1, the section controller 600 recognizes that it is the highest section, assigns its own address to 1, generates a new address 2 with an increment of 1 to the assigned address 1, and sends it to the lower section controller. Transmit (S4), (S5). Since the lower section controller 600 inputs the address set information of 2, the lower section controller 600 allocates the 2 as its own address, and transmits a new address 3 having an increment of 1 to the next section controller (S6). Repeating the above process, the addresses of the subsequent section controllers are allocated continuously, and the lowest section controller recognizes that there is no subsequent section controller, and terminates the transmission of the newly generated address set information.

As shown in Fig. 6, one channel connected to the main controller is connected to the lowest section controller (section controller n) continuously from the highest section controller (section controller 1).

When initialization information is input from the main controller 300, the address of each section controller is set to zero. In addition, when address set information = 1 is input, section controller 1 converts and stores an initial address value to 1, generates address set information = 2, and transmits it to section controller 2, and section controller 2 sends address set information = 2 It receives the input and stores it as a new address, generates new address set information = 3, and sends it to the next section controller 3. Repeat this process to assign addressers to the lowest section controller.

When the address allocation process is completed, the main controller 300 transmits a data frame having address information and image information to each section, and the section controllers detect a data frame matching the assigned address and display the image on the LED. To be displayed.

4 to 6 are configured to set the lowest address in the top section and to increment the address of sections consecutive in the top section by one. However, the main controller may be configured to set the highest number of addresses in the top section and to decrement the addresses of sections consecutive to the top section by one.

In addition, the address setting information may not only be input in the uppermost section, but may also be input in the lowermost section and sequentially pass through the sections to reach the uppermost section. In this process, the lowest address may be assigned to the lowermost section. You can assign an address that increments by 1 to subsequent sections, or assign the highest address to the lowest section, and then assign an address that increments by 1 to subsequent sections.

There may be a number of address allocation methods modified from the above methods, but such modifications can be naturally modified by those skilled in the art, and the protection scope of the present invention is defined by the following claims.

According to the present invention having the above objects and configurations, since the address can be assigned to each section in software without using a dip switch, the electronic board can be manufactured at low cost, and the installation can be performed quickly.

In addition, since the mechanical dip switch is not used, failure factors due to aging of the dip switch can be eliminated.
