LED module device with intelligent station number and method of setting station number using the same

The present invention relates to an LED module device having an intelligent station number and a station number setting method, and more particularly, an LED module device and station number setting that can efficiently perform work and operation related to LED signage by applying intelligent station number setting technology to an LED module it's about how

An LED module with a parallel communication structure must have a station number in order to receive the LED control signal of the LED module itself. That is, it is a method in which the LED control signal corresponding to its station number is extracted from the received LED control signals, and the LED is driven by the extracted signal.

In general, after production and assembly of LED signage, each station number for horizontally connected LED modules is set to On(1)/Off (0 ) to set the station number.

And, when the replacement of the LED module is requested during maintenance, set the same station number as the faulty LED module-station number, and check that each LED module is displayed normally on the front of the LED signboard to check whether it is displayed normally.

In order to prevent errors due to such a complicated operation procedure, it is necessary to simplify the process by applying an intelligent station number setting technology that automatically sets the station number to eliminate errors in prior work.

Conventional LED sign-related work sequence is 'LED sign assembly → Horizontally connected LED module-station number selection → Check the display contents of the LED sign board → If there is an error in the display content (LED module damage or abnormal state) → the corresponding LED module- Station number confirmation → LED module replacement → LED module-station number reset'.

Therefore, the operator must know the concept of BCD (binary decimal number) to reset the station number, and it is essential to reset the station number by combining On(1)/Off(0) with the DIP switch built into the LED module. .

This LED signboard-related work has a problem in that it consumes an excessively large amount of work time in installation and maintenance, and increases the work difficulty.

In addition, each LED module (11, 12, 13) may be configured to include a station number mode unit 120 connected to the intelligent station number control unit (100). The station number mode unit 120 is implemented in the form of a button or a switch, and an automatic mode or a manual mode may be selected according to the operation of the button. For example, the button is operated through an action of the user (operator) pressing the station number mode unit 120 in the form of a button, so that an automatic mode or a manual mode can be selected.

As a specific example, when the user presses the station number mode unit 120 in the form of a button in the manual mode state, the automatic mode may be selected, which can be viewed as a change of 'manual mode → automatic mode'. The intelligent station number control unit 100 connected to the station number mode unit 120 may determine whether the station number mode is an automatic mode or a manual mode based on the state of the station number mode unit 120 .

Referring to FIG. 2, for example, the main communication control unit 101 of the second LED module 12, which is any one of the plurality of LED modules, and the secondary communication unit of the first LED module 11 and polling It is a structure connected by serial communication of the second LED module 12, and the main communication control unit 101 of the second LED module 12 transmits the station number-synchronization command packet at a predefined period and waits for a response. The communication control unit 102 receives the packet in real time, analyzes the received packet, and if it is a station number-synchronization command, the LED module of the first LED module 11-station number including the station number-synchronization response command packet is created and transmitted. can

And, when the station number-synchronization response command packet is received from the secondary communication control unit 102 of the first LED module 11 in a state where the main communication control unit 101 of the second LED module 12 is waiting for a response, the received Analyze the station number-synchronization response command packet to extract the receiving station number, and if the receiving station number is the initialization value (0xFF), the initialization value (0xFF) is set as the auto-station number; otherwise, the value obtained by adding 1 to the receiving station number is automatically- It can be set by station number. That is, it is possible to set the auto-station number of the second LED module 12 .

And if the main communication control unit 101 of the second LED module 12 does not receive the station number-synchronization response command packet from the secondary communication control unit 102 of the first LED module 11 for a predefined response waiting time, It is determined that communication between the LED modules is faulty or not connected, so that the auto-station number, that is, the LED module-station number of the second LED module 12, can be set to 0x00.

The LED module device having an intelligent station number according to an embodiment of the present invention includes a manual station number management unit 103 in the intelligent station number control unit 100 of at least one LED module among a plurality of LED modules 11, 12, 13. can be configured.

The manual station number management unit 103 can read the value of the manual station number setting switch 150 and apply it as a manual-station number.

In the present invention, the manual station number setting switch 150 may be configured as a DIP switch, and the DIP (dual in-line package) switch is a series of ON-OFF switches, which serves to connect the circuits at both ends and allows the user without changing the hardware. It allows a (operator) to arbitrarily select a function on the circuit board, and unlike a tact switch that maintains a state only when pressed, it may be in the form of a toggle switch that maintains a state when selected.

The intelligent station number control unit 100 can read the value of the manual station number setting switch 150 as described above and apply it to the manual-station number, and this operation can be performed after the LED module-station number is initialized.

In addition, the LED module device having an intelligent station number according to an embodiment of the present invention includes a first signal control terminal 211 and a second signal control including a serial part and a parallel part in each of a plurality of LED modules (11, 12, 13) A terminal 212 is provided, and the second signal control terminal 212 of any one of the plurality of LED modules may be connected to the first signal control terminal 211 of the adjacent LED module by a signal cable 220 .

And, the serial part of the first signal control terminal 211 of the LED module having an intelligent station number is connected to the secondary communication control unit 102, and the serial part of the second signal control terminal 212 can be connected to the main communication control unit 101. have. In addition, the parallel portion of the first signal control terminal 211 is directly connected to the parallel portion of the second signal control terminal 212, so that a plurality of LED modules 11, 12, 13 is connected to the signal control cable 220 by such a connection configuration. connected to enable efficient communication.

The LED module device having an intelligent station number according to an embodiment of the present invention may be configured by mixing with an existing LED module having the same signal structure of a parallel signal method as shown in FIG. 3 .

Referring to FIG. 3 , the fourth to sixth LED modules may be arranged in the order from right to left, and the second signal control terminal 212 of the fifth LED module 15 and the fourth LED module 14 are 3 The signal control terminal 213 is connected with an existing signal control cable 221 without a serial part, and the fourth LED module 14 is simply provided with an LED driving unit 200 and a manual station number setting switch 150 and an intelligent station number control unit. It is an existing LED module that does not include ( 100 ), and the fifth LED module ( 15 ) and the sixth LED module ( 16 ) are LED modules including the intelligent station number control unit ( 100 ).

In this way, when the LED module device having an intelligent station number according to an embodiment of the present invention is configured and connected in the form as shown in FIG. 3, the LED module of the fourth LED module 14 - the station number manual station number setting switch 150 When the value is 0x00, the main communication control unit 101 of the fifth LED module 15 sends the station number-synchronization command packet to the fourth LED module 14 at a predefined period, even if the fourth LED module 14 Since the intelligent station number control unit 100 is not provided, the main communication control unit 101 and the secondary communication control unit 102 cannot be provided either, and for this reason, the generation of the station number-synchronization response command packet is impossible. Accordingly, the main communication control unit 101 of the fifth LED module 15 may set the auto-station number to 0x00.

However, if the main communication control unit 101 of the fifth LED module 15 sets the auto-station number to 0x00, the auto-station number '0x00' can be applied as the LED module-station number when the station number mode is the automatic mode. In this case, since the station number of the fifth LED module 15 may overlap with the station number of the fourth LED module 14 , the operator (user) operates the manual station number setting switch 150 of the fifth LED module 15 . Thus, the LED module of the 4th LED module 14 - 1 plus 1 is the station number - manual-station number (ex. LED module of the fourth LED module 14 - When the station number is 4, the LED of the 5th LED module 15) It is preferable to set the module-station number to 5 and set the manual station number setting switch 150), and to set the station number mode unit 120 to manual mode.

Accordingly, the intelligent station number control unit 100 of the fifth LED module 15 monitors the station number mode unit 120 in real time to determine that it has been set to the manual mode, and to apply the LED module-station number to manual-station number. will be.

When the sub communication control unit 102 of the fifth LED module 15 receives the station number-synchronization command packet from the main communication control unit 101 of the sixth LED module 16, based on this, the LED module-station number including the station number - After generating the synchronization response command packet, the generated station number-synchronization response command packet is transmitted to the main communication control unit 101 of the sixth LED module 16 again.

Then, the main communication control unit 101 of the sixth LED module 16 receives the packet in real time, and if the received packet is a station number-synchronization response command packet, it analyzes the packet to extract the receiving station number, and the extracted receiving station number is If it is the initialization value (0xFF), the initialization value (0xFF) is set as the auto-station number, otherwise, the value obtained by adding 1 to the extracted receiving station number can be set as the auto-station number of the sixth LED module 16 itself.

If the receiving station number extracted by analyzing the station number-synchronization response command packet in the 6th LED module 16 is 'station number-1', the LED module-station number of the 6th LED module 16 is a value obtained by adding 1 to the extracted reception station number ' It can be station number-2'.
