The control target device and the control device according to the present invention utilize the data frame structure of the Zigbee standard as described below to enable the command of the control target device and report the status of the control target device.

The frame structure used in the present invention adopts a super-frame structure defined by the Zigbee standard, but uses a time slot of a GTS (Guaranteed Time Slot) type that uses a predetermined time slot to minimize power consumption and minimize power consumption. Apply super-frame. The super-frame is transmitted from the controller and consists of 16 time slots, including beacon frames.

Frames exchanged (GTS type) in a designated time slot during a super-frame are called information frames. The types of information frames exchanged between a control device and a control target device include beacon frames, data frames, acknowledgment frames, and the like. There are Command frames, and they are identical to the frame types specified in the ZigBee standard and their structure follows the ZigBee standard.

In this state, the control unit 210 (220) of the control device 20A (20B) transmits a beacon frame message (Beacon) to the control unit of the corresponding control target device, followed by an ID set command frame message (ID Set Command) Is transmitted to the control unit of the control target device.

The control unit of the control target device that receives the beacon frame message (Beacon) and the ID set command frame message (ID Set Command) through the RF transmitter / receiver 112 (see FIG. 10) is for confirming reception of these messages. The acknowledgment frame message (Acknowledge) is transmitted to the corresponding control device 20A (20B).

The control unit 210 or 220 that receives the acknowledgment frame message (Acknowledge) through the control unit 20A or 20B through the RF transmitters 211 and 221 determines the number of the control target device and controls the unit ( 20A) 20B generates a network address (see FIG. 16) containing 4 bytes of address extension 4 bytes together with 4 bytes of the control target device ID having the format of FIG. 15 including its own S / N.

Thereafter, the control unit 210 or 220 of the control device 20A or 20B divides the generated 8-byte network address by 2 bytes, and uses each of the divided 2 bytes using the data frame shown in FIG. A data frame message [ID (0) to ID (3)] is generated, and the frame message [ID (0) to ID (3)] is generated through the RF transceiver 211 and 221 four times. Send to the control target device. In this case, the sender and receiver addresses of the data frame message are ignored.

Subsequently, the control unit 110 (see FIG. 10) of the control unit of the corresponding control target device receives a data frame message ID (0) to ID (3) every time through the RF transmitter / receiver 112. An acknowledgment frame message for confirmation is transmitted through the RF transmitter / receiver 112.

In this way, when the transmission frame confirmation frame message for the fourth data frame message [ID (3)] is received, the control unit 210 or 220 of the control device 20A or 20B receives the ID (network Recognizing that the address is normally transmitted, the corresponding ID (network address) is stored in the built-in EEPROM of the controller 210 or 220 in correspondence with a specific key designated by the user. On the other hand, the control unit 110 (see Fig. 10) of the control unit of the control target device sends an acknowledgment frame message after receiving the fourth data frame message [ID (3)] and then receives its ID (network address) normally. Recognition of the ID, and stores the ID (network address) in the built-in EEPROM of the controller 110.

Through this process, the network address of the control target device is set and used as the network address of the control target device when exchanging information by communication with the control device.

Next, a procedure for ID exchange of the control target device between the control devices will be described with reference to FIG. In this case, only the ID of the control target device (exactly the network address) is transmitted from the control device 1 (for example, the mobile control device 20A) to the control device 2 (for example, the mobile control device 20B). Although it will be described, it will be readily understood that ID transmission in the reverse direction can be made in the same manner.

First, when the user operates the key input unit 213 (see FIG. 11) of the control device 20A and selects the ID exchange mode from the menu screen displayed on the display 212, the control unit 210 of the control device 20A Enters ID exchange mode. On the other hand, when the user also manipulates the key input unit 223 (see FIG. 12) of the control device 20B and selects the ID setting mode from the menu screen displayed on the display 222, the control unit 220 of the control device 20B also has Enter ID setting mode.

In this state, the user operates the key (button) corresponding to the transmission in the key input unit 213 (see FIG. 11) of the control device 20A to identify the ID of at least one control target device managed by the control device 20A. To the control device 20B.

Accordingly, the control unit 210 of the control device 20A sequentially reads the IDs of all the control target devices that are managed by the key input unit 213 according to the input and stored in the built-in EEPROM, respectively, as follows. The read key number and ID are transmitted to the control device 20B, respectively.

That is, the control unit 210 of the control device 20A first generates a beacon frame message (Beacon) as shown in FIG. 4 and outputs it through the RF transmitter / receiver 211. At this time, the destination address DA is an address of the control device 20B and the source address DS is an address of the control device 20A.

Then, the control unit 210 of the control device 20A first inserts the key number for the first control target device into the 2-byte data field using the data frame message as shown in FIG. A message (key number) is generated and output through the RF transmitter / receiver 211. Also at this time, the destination address DA is an address of the control device 20B and the source address DS is an address of the control device 20A.

Subsequently, the control unit 220 of the control device 20B receiving the data frame message for the key number generates and sends an acknowledgment frame message, and the control unit of the control device 20A receiving the acknowledgment frame message (Acknowledge). 210 separates the 8-byte ID (network address) for the first control target device by 2 bytes, and uses the data frame message as shown in FIG. 5 to separate the ID (network) into the 2-byte data field. The first two bytes of the address) are inserted to generate a data frame message [ID (0)] for the first two bytes of the ID, and output through the RF transmitter / receiver 211. Also at this time, the destination address DA is an address of the control device 20B and the source address DS is an address of the control device 20A.

Thereafter, the control unit 210 of the control device 20A that receives the acknowledgment frame message (Acknowledge) from the control device 20B uses the data frame message in the same manner for the second to fourth two bytes for the first control target device. Data frame message [ID (1),... , ID (3)] and outputs it through the RF transmitter / receiver 211.

In this way, the control unit 220 of the control device 20B, which has received both the 2-byte key number and the 8-byte ID (network address) for the first control target device from the control device 20A, receives in its own built-in EEPROM. Stores one key number and ID.

When all the IDs are transmitted from the control device 20A to the control target device managed by the above-described method, the control unit 210 of the control device 20A ends the transmission and enters the standby mode. . On the other hand, the controller 220 of the control device 20B controls to enter the standby mode if there is no data frame message received for a specified time.
