Abstract

The present invention relates to the distributed processing of the connection of the lighting device consisting of a series connection, in particular to one or more lighting devices configured in a series connection and capable of automatic addressing and a controller for transmitting control signals and data to the device. In the lighting system that is configured, the start address of the automatic addressing command is provided by installing a serial / parallel distribution device that separates the lighting device composed of the serial connection into a plurality of small group serial connections and controls each separate serial connection to produce the same result. By assigning the sum of the number of lighting devices of the small groups connected to the serial / parallel distribution unit to the next-generation serial / parallel distribution unit as the starting address value, automatic addressing can be made in sequence as if the entire lighting devices were connected in series.

When the existing lighting system shown in FIG. 1 is distributedly connected as shown in FIG. 3, each lighting device should be given a unique address as shown in FIG. 1 for the automatic addressing command. The configuration of the serial-parallel distribution device (400; 400-1 ~ 400-M) of the present invention for having this function is

The serial and parallel distribution device 400,

A receiving unit 401 for receiving commands and data from the controller 100 or the front end;

Analyzes the command and data received by the receiving unit 401, and controls the command and data to be delivered to the lighting devices of the lighting device subgroup connected to the corresponding serial / parallel distribution device and the serial / parallel distribution device of the next stage.

It is characterized by making the same as the addressing result when configured with one serial connection.

5 is a flowchart illustrating a method of controlling parallel / parallel distribution of a lighting apparatus according to the present invention.

As shown in the drawing, a plurality of lighting devices are serially connected in small groups, a serial / parallel distribution device is installed in each small group, and a serial / parallel distribution device of each small group is connected in series to transmit commands and data. In the control method of the serial-parallel distribution device, the serial-parallel distribution device,

First step (S10) for determining whether the automatic addressing command is received by receiving the command and data, and if the automatic addressing command is not received, the first and second output unit 404, 405 received through A second step (S20) of outputting the command and the data as it is; When the automatic addressing command is received in the first step (S20), the third step of outputting the automatic addressing command to the lighting device of the lighting device small group connected to the serial-parallel distribution device through the first output unit 404 ( S30); Simultaneously with the third step, the start address of the automatic addressing command is changed according to the number of lighting devices of the lighting device small group connected to the corresponding serial / parallel distribution device, and then the serial / parallel distribution device of the next stage through the second output unit 405. The fourth step S40 of outputting is performed.

When a plurality of lighting devices are connected in series to one controller, and each of the lighting devices has an automatic addressing function, the command and data transmitted from the controller 100 are transmitted through a separate receiver or directly to the lighting device. When the automatic addressing command is received, the address is sequentially increased from the starting address value specified in the command, and each lighting device is assigned an address. When the specified starting address is '1', each lighting device is addressed in order from 1 to N.

In FIG. 3, the command and the data transmitted from the controller 100 are received by the first serial distribution device 1 400-1. The serial / parallel distribution device 1 (400-1) analyzes the received commands and data, and the commands and data other than the automatic addressing command remain intact with the subordinate lighting device (lighting device 1-lighting device 4) and the next serial distribution device 2 ( 400-2). That is, when the automatic addressing command is received, the subordinate lighting device transfers the command as it is and before the automatic serial addressing device 2 400-2, the subordinate lighting device address number input unit 403. Get the value from and increase the specified start address and pass it to the next serial-parallel distribution unit 2 (400-2).

In FIG. 3, when an auto-addressing command in which the start address is set to '1' is received in the serial / parallel distribution device 1 (400-1), the lighting device subordinated through the first output unit 404 (lighting device 1 to lighting device 4). Command) As a result, the subordinate lighting device (lighting device 1-lighting device 4) is automatically addressed from # 1 to # 4. However, as in FIG. 1, the command is not transmitted from # 4 to # 5. The first serial distribution device 1 (400-1) receives a value through the subordinate lighting device address number input unit 403, increases the starting address, and then the second serial distribution device 2 through the second output unit 405. To 400-2. In this case, a new starting address of '5' is specified in addition to the received address '1' received from the input unit 403 of the number of lighting device addresses dependent on the serial / parallel distribution unit 1 (400-1). The addressing command is transmitted to the serial / parallel distribution unit 2 (400-2).

Since the starting address included in the auto-addressing command received from the second serial distribution device 2 (400-2) is '5', the address of the subordinate lighting devices (lighting devices 5-lighting devices 8) is # 5-# 8. The next serial-parallel distribution unit 3 (400-3) is assigned an automatic addressing command having a start address of '9'. If this operation is repeated, as a result, all the lighting devices are assigned the address shown in FIG.

Therefore, using the present invention, the controller 100 can control the same as in the lighting system in which all the lighting devices are connected in series. The lighting devices are connected in series with a plurality of lighting devices in small groups, the small groups are separated, and each lighting device small group is provided with one serial / parallel distribution device, and the serial / parallel distribution devices receive received commands and data. Outputs to the subordinate lighting device subgroup and the next serial / parallel distribution device, but if it is an automatic addressing command, it outputs to the subordinate lighting device subgroup as it is, and the start address of the automatic addressing command is output to the subordinate lighting device. By increasing the number of devices to be delivered, sequential auto-addressing can be achieved as if the lighting devices were all connected in series.
